JP7582701B2 - Piping design device, design system, and installation support method - Google Patents

Description

The present invention relates to a design device, a design system, and an installation support method for piping and the like.

Devices are known that assist with structural calculations and designs of beams, piping, etc.

Specifically, when creating a through hole in a steel beam, the computer judges whether the through hole meets the applicable conditions such as the hole diameter or installation position. For example, the computer calculates the hole diameter of the through hole, the material of the beam, the web width-thickness ratio, the beam depth, the minimum pitch of adjacent holes, the distance from the beam end to the hole center, the distance from the high ring end to the gusset plate end, and the amount of eccentricity, and makes the judgment. In this way, a method of preventing unnecessary interruptions to construction work is known (for example, Patent Document 1, etc.).

JP 2007-164322 A

However, conventional methods do not take into account the case where multiple support members are installed. In other words, even if a support member needs to be installed when installing it according to a single rule, it may end up being an unnecessary support member when other support members are taken into consideration.

The present invention was made in consideration of the above problems, and aims to reduce the installation of unnecessary support members when installing multiple support members.

The design device etc. according to each embodiment of the present invention includes the following configuration:

A design device for supporting installation of a plurality of support members for supporting an object to be installed on a building,
a first support member data input means for inputting first support member data (e.g., an insert master, etc.) that defines a first rule for installing a first support member among the plurality of support members;
a second support member data input means for inputting second support member data (e.g., an earthquake-resistant support material master, etc.) that defines a second rule for installing a second support member that is installed to make the object earthquake-resistant among the plurality of support members;
An installation range input means for inputting an installation range in which the first support member and the second support member are installed (for example, an installation range RG input as shown in FIG. 26 );
a second support member installation means (e.g., step S16 in FIG. 25 ) that installs the second support member in the installation range based on the second rule;
The installation range includes a first support member installation means (for example, step S15 in FIG. 25) that installs the first support member based on the first rule and the position where the second support member is installed.

When installing multiple support members, if the installation of the other support members is not taken into consideration, the rules dictate that, for example, inserts are installed at intervals of "2.0 m". On the other hand, the rules dictate that, for example, earthquake-resistant support members are installed at intervals of "6.0 m". Note that the starting point for calculating the intervals is assumed to be the same. In such a case, the locations where the inserts and earthquake-resistant support members are installed overlap at least at the positions "6.0 m", "12.0 m", and "18.0 m".

On the other hand, when installing multiple support members, taking into account the installation of other support members, the installation of inserts can be omitted at positions such as "6.0 m", "12.0 m", "18.0 m", etc., i.e. positions where the insert and earthquake-resistant support member are calculated to be installed overlappingly. In other words, even if a support member is deemed necessary to install when installing based on a single rule, taking into account the other support members, an unnecessary support member may be generated. Therefore, when installing multiple support members, the installation of unnecessary support members can be reduced.

Further, the first support member installation means and the second support member installation means are
If there is an uninstallable portion (e.g., vertical pipe portion OB) where the first support member or the second support member cannot be installed, the first support member or the second support member is installed while avoiding the uninstallable portion (e.g., installed as shown in Figure 28).

The target object has parts where earthquake-resistant support members, etc. cannot be installed, such as the vertical pipe section. If earthquake-resistant support members are installed at intervals based on the rules, it may be that the earthquake-resistant support members will be installed in the vertical pipe section. In such a case, the earthquake-resistant support members are installed in the part that avoids the vertical pipe section, as shown in Figure 28. In this way, the design device recognizes the vertical pipe section, etc., and installs the earthquake-resistant support members while avoiding the vertical pipe section, etc.

Even if earthquake-resistant support members are to be installed in the vertical pipe section, it is difficult to install earthquake-resistant support members in the vertical pipe section OB during actual construction work. If earthquake-resistant support members are installed in such a section, it is often necessary to reinstall the earthquake-resistant support members manually, etc.

In addition, when the installation location of an earthquake-resistant support member is changed in this way, other earthquake-resistant support members may also need to be reinstalled. Therefore, if the earthquake-resistant support members are positioned to avoid the vertical pipe section, the burden of the work of reinstalling the earthquake-resistant support members can be reduced.

Further, the first support member installation means and the second support member installation means are
The first support member or the second support member is installed while avoiding the non-installation portion so that the interval between the first support member or the second support member becomes narrow (for example, installed as shown in FIG. 28).

If the spacing between the support members is increased, the spacing may not satisfy the specified rules. On the other hand, if the spacing between the support members is decreased, the spacing will often satisfy the specified rules. Therefore, when avoiding areas where installation is not possible, narrowing the spacing between the support members will result in an installation that satisfies the specified rules.

In addition, if the object is branched, the first support member installation means and the second support member installation means install a plurality of the first support members or the second support members for the branched object, compare the spacing between the first support members or the second support members, and display the wider spacing (for example, as shown in FIG. 29).

For example, if there is a branch as shown in Figure 29, the branch will result in multiple routes. For this reason, earthquake-resistant support members, etc. are installed for each route. Therefore, multiple intervals may occur, as shown in Figure 29. In such a case, the wider interval is the one that is displayed by the interval display. In many cases, the wider interval exceeds the specified rule and does not satisfy the rule. Therefore, if the interval display displays the one that is most likely to not satisfy the rule, the user can easily check whether the specified rule is being satisfied.

The distance between the first support member or the second support member installed within the installation range and the first support member or the second support member installed outside the installation range is displayed (for example, as shown in Figure 30 or Figure 40).

In this way, even if it is outside the installation range, if the spacing is calculated taking into account the support members that will be installed in advance, the work of the user to calculate the spacing between the "existing earthquake-resistant support members" and the newly installed support members can be reduced, reducing the workload.

In addition, when moving the starting point at which the installation of the first support member or the second support member begins to a new starting point, an auxiliary line is displayed to assist in the movement of the starting point (for example, as shown in FIG. 32).

For example, users often want to set a new starting point at a position that is aligned in the X-axis direction with earthquake-resistant support members installed on other pipes. Therefore, as shown in FIG. 32, if positions where the X-axis direction is aligned with other earthquake-resistant support members are shown with auxiliary lines, the user can easily understand the positions of candidate points. In this way, when moving the starting point, it is easier for the user to perform the operation if there is assistance such as the display of auxiliary lines.

In addition, when an operation is performed to move the starting point from which the installation of the first support member or the second support member is to be started to a new starting point, when the cursor used in the operation approaches a candidate point that is a candidate for the new starting point, the cursor is assisted in being aligned with the candidate point (for example, displayed as shown in FIG. 32).

In many cases, the user will move the starting point to a position that is aligned in the X-axis direction with earthquake-resistant support members installed on other pipes, i.e., to a position that is a candidate point in the example shown. However, when using a mouse or other device to specify the position of a candidate point, there are cases where an incorrect position is specified due to operational errors, etc.

Therefore, as described above, if there is assistance in aligning the cursor with the candidate point as the cursor approaches, the candidate point can be specified with high accuracy.

In addition, a design system for supporting the installation of a plurality of support members for supporting an object to be installed in a building includes:
a first support member data input means for inputting first support member data that defines a first rule for installing a first support member among the plurality of support members;
a second support member data input means for inputting second support member data defining a second rule for installing a second support member to make the object earthquake-proof among the plurality of support members;
an installation range input means for inputting an installation range in which the first support member and the second support member are installed;
a second support member installation means for installing the second support member in the installation range based on the second rule;
The installation range includes a first support member installation means for installing the first support member based on the first rule and the position where the second support member is installed (for example, a design system such as that shown in FIG. 1).

In addition, an installation support method performed by a design device that supports installation of a plurality of support members that support an object to be installed in a building includes the following steps:
a first support member data input step in which the design device inputs first support member data that defines a first rule for installing a first support member among the plurality of support members;
a second support member data input step in which the design device inputs second support member data that defines a second rule for installing a second support member, among the plurality of support members, that is to be installed to make the object earthquake-proof;
an installation range input step in which a design device inputs an installation range in which the first support member and the second support member are to be installed;
a second support member installation procedure in which the design device installs the second support member in the installation range based on the second rule;
The design device includes a first support member installation procedure for installing the first support member in the installation range based on the first rule and the position at which the second support member is installed (for example, a process such as that shown in Figure 25).

In addition, a program for causing a computer to execute an installation assistance method for assisting in the installation of a plurality of support members for supporting an object to be installed in a building includes:
a first support member data input step in which a computer inputs first support member data that defines a first rule for installing a first support member among the plurality of support members;
a second support member data input step in which the computer inputs second support member data that defines a second rule for installing a second support member, among the plurality of support members, that is to be installed to make the object earthquake-proof;
an installation range input step in which a computer inputs an installation range in which the first support member and the second support member are to be installed;
a second support member installation procedure in which the computer installs the second support member in the installation range based on the second rule;
The computer executes a first support member installation procedure in which the first support member is installed in the installation range based on the first rule and the position at which the second support member is installed (for example, a process such as that shown in Figure 25).

According to each embodiment of the present invention, when multiple support members are installed, it is possible to reduce the installation of unnecessary support members.

First Embodiment
<Overall configuration example>
1 is a conceptual diagram showing an example of the overall configuration of a design system and an example of the hardware configuration of a design device. For example, the design device according to this embodiment is used in a design system 10 as shown in the figure.

Specifically, the design system 10 includes, for example, a PC (Personal Computer, hereinafter referred to as "PC 11"), which is an example of a design device, goggles 12, and a pointer device 13.

As shown in the figure, the design system 10 is connected to a network NW such as the Internet. It is then connected to external devices M1, M2, M3, etc. via the network NW. When data or operations, etc. are input from the external devices M1, M2, M3, etc. connected in this manner, the design system 10 accepts the data or operations, etc. via the network NW. In other words, the design system 10 transmits and receives data to and from the external devices M1, M2, M3, etc. via the network NW.

<Example of hardware configuration of design equipment>
As shown in the figure, the PC 11 has a hardware configuration including a CPU (Central Processing Unit, hereinafter referred to as "CPU 11H1"), a storage device 11H2, an interface 11H3, and a communication device 11H4.

The CPU 11H1 is an example of a calculation device and a control device. That is, the CPU 11H1 cooperates with the storage device 11H2 based on a program to realize processing or control.

The storage device 11H2 is a main storage device such as a memory. The storage device 11H2 may also have an auxiliary storage device such as a hard disk or SSD (Solid State Drive). The storage device 11H2 stores programs, data, etc.

The interface 11H3 connects peripheral devices such as the goggles 12 and the pointer device 13, for example, by wire or wirelessly, and transmits and receives data with the peripheral devices. Specifically, the interface 11H3 is, for example, a connector and a processing IC (Integrated Circuit). The interface 11H3 may also be connected to peripheral devices via a network.

The interface 11H3 connects peripheral devices such as the goggles 12 and the pointer device 13. The goggles 12 and the pointer device 13 are examples of devices for using a virtual space. In other words, the goggles 12 and the pointer device 13 display the virtual space and then accept operations on the displayed virtual space.

The goggles 12 are an example of an output device that displays a virtual space. For example, the goggles 12 are a head mounted display (HMD).

The pointer device 13 is an example of an input device that inputs operations such as pointing at objects displayed in the virtual space or selecting menus.

<Data configuration example>
2 is a block diagram showing an example of the configuration of data realized by the design system 10. For example, by using the design system 10, data such as that shown in the figure can be handled.

First, various data are input to the design system 10 by an external device or an input device. Specifically, for example, design data D01, construction data D02, operation data D03, library data D04, price list data D05, specification data D06, equipment data D07, and attribute information data D08 are input. Note that other data may also be input to the design system 10.

As shown in the figure, the design data D01, construction data D02, and operation data D03 are data created for specific purposes, such as "design," "structure," "air conditioning," "sanitation," and "electricity." For example, the "design" data in the design data D01 is data showing blueprints and the like related to the design of a building.

Library data D04 is data that indicates, for example, the "shape" and "attributes" of a building or parts used to construct a building.

The price list data D05 is data that indicates the prices of parts and the like procured in construction. For example, the price list data D05 is data such as the following:

Figure 3 is a diagram showing an example of price list data. For example, as shown in the figure, the prices of each part are input corresponding to the part name, such as "Part 1," "Part 2," and "Part 3." Note that multiple prices may be input even for the same part, such as "Part 2" as shown in the figure. For example, the price may differ for the same part if the supplier is different or the purchasing conditions, such as bulk purchase, are different. For this reason, multiple prices may be input for one part, such as "Part 2" as shown in the figure, in the price list data D05.

Specification data D06 and equipment data D07 are data that indicate the specifications of equipment and parts to be installed in a building.

The attribute information data D08 is data indicating, for example, various settings and related information (hereinafter referred to as "attribute information") for the BIM model. Specifically, as shown in the figure, the attribute information data D08 includes inputs such as "Properties (various settings)", "ID (Identification)", "Source file name", "Project information", "Block name", "Plan name", "Dimensions", "Installation date", "Installation conditions such as temperature", "Area information (area type and area name, etc.)", "Material information such as inclusions", "Type parameters", and "Work data".

For example, information such as specifications regarding buildings, equipment, parts, etc. is stored in the form of document data D10, skeleton data D11, table data D12, etc.

For example, the BIM model is composed of at least CAD data D13 and attribute information data D08. However, when using the BIM model, other data such as document data D10, skeleton data D11, or table data D12 may be referenced.

As shown in the figure, if there is price list data D05, for example, cost data D09 like the one below can be generated.

Figure 4 is a diagram showing an example of cost data. As shown in the figure, cost data D09 indicates data used, for example, for cost calculations and the like. Specifically, first, with price list data D05 and the like, the price of each part can be ascertained. Then, with a BIM model, the quantity of each part used in a building can be ascertained. Next, by calculating "price x quantity," the cost of each part, which is a breakdown of "material costs," can be ascertained.

When design data D01, etc. is input, the design drawings, etc. are stored, for example, as CAD data D13 as shown below.

Figure 5 is a diagram showing an example of CAD data. As shown in the figure, CAD data D13 is 3D data, etc. Note that CAD data D13 may also include 2D data. Furthermore, CAD data D13 may include multiple data depending on the level of detail or the purpose of use, such as "design drawing level" to "working drawing level," etc.

Then, for example, technical review data D14, construction plan data D15, and construction management data D16 may be generated based on the BIM model, etc. Below, an example in which data as shown in the figure is generated will be described.

When cost data D09 is available, for example, estimate processing PS01, cost management processing PS02, and budget management processing PS03 can be executed. When such processing can be executed, the design system 10 can create documents such as design documents FL1, invoices FL2, or estimates FL3. In other words, estimate processing PS01 can calculate amounts and the like to be written on invoices FL2 and estimates FL3, etc.

In addition, the cost management process PS02 can calculate amounts used in cost management, such as variable costs and fixed costs, making it possible to calculate amounts to be stated in documents such as the design document FL1.

The budget management process PS03 can calculate amounts and the like used to manage the budget. For example, expected costs used to create the budget or progress rates used to manage using the percentage of completion method are calculated. In this way, the budget management process PS03 can calculate amounts and the like to be written on the estimate FL3.

With technical study data D14, for example, processes such as heat and air current simulation PS04 and static pressure and head calculation PS05 can be executed. Furthermore, with technical study data D14, processes such as placement simulation PS06 of mounting frames, steel materials, hoists, anchors, etc. can be executed. Furthermore, with technical study data D14, sound simulation PS07 such as noise, sound deadening, and sound insulation can be executed. In addition, with technical study data D14, processes such as air volume and water volume distribution calculation and wind and water leakage volume calculation PS08 can be executed.

In other words, with the technical study data D14, the design system 10 can execute various simulations or scientific and technological calculations. Therefore, the design system 10 can execute simulations and output simulation results.

With the construction planning data D15, it is possible to create various plans, such as process planning PS09, safety planning PS10, artificial planning PS11, construction method planning PS12, delivery planning PS13, and trial operation planning PS14.

For example, construction plan data D15 is data such as the following:

Figure 6 is a diagram showing an example of construction plan data. As shown in the figure, the construction plan data D15 is data showing schedules, for example, in the form of a so-called Gantt chart. In other words, the construction plan data D15 is data showing a schedule of work, etc. to be performed to construct a building. Therefore, when data such as the construction plan data D15 is available, it is possible to execute processing such as the process plan planning PS09, which creates a process plan based on the schedule of each process shown in the construction plan data D15.

Similarly, plans for safety at each process, plans for people at each process, plans for construction methods, plans for bringing in equipment, etc., and plans for trial runs can be prepared by processes such as safety plan preparation PS10, manual plan preparation PS11, construction method plan preparation PS12, delivery plan preparation PS13, and trial run plan preparation PS14.

The construction management data D16 is data used for various management in the construction of a building. For example, at a construction site, progress, actual items, and costs are managed. Of these, the construction management data D16 is used, for example, to manage progress and actual items. Specifically, with the construction management data D16, processes such as progress management PS15, order and delivery management PS16, and inspection and record management PS17 can be executed. For example, management tables or records are created by processes such as progress management PS15, order and delivery management PS16, and inspection and record management PS17.

The change data D17 is data that is generated when an operation is performed in VR (Virtual Reality) that is displayed based on the CAD data D13, etc., to change the materials and equipment (including equipment, facilities, or parts thereof that are part of the building; hereinafter simply referred to as "materials and equipment") installed in the building.

Specifically, a building is designed, and the design details are input into CAD data D13, etc. Then, the layout of materials and equipment in the building is also input into the CAD data D13. With such CAD data D13, the completed state of the building can be virtually displayed, for example, on goggles 12, by VR display, etc. Thus, users UR, etc. can see the completed state of the building and the layout of materials and equipment in the building in a virtual space, even during the design stage. In this way, using VR display to show a forecast of the completed building, for example, can prevent discrepancies from occurring between the client of the building and the designer.

Furthermore, if the user UR finds that the placement of the equipment and materials differs from his/her intention, he/she looks at the VR display displayed in the VR display process PS19 and performs an operation to change the placement of the equipment and materials. For example, in the overall configuration shown in FIG. 1, the user UR uses the pointer device 13 in the virtual space displayed by the goggles 12 to specify the equipment and materials to be changed and performs an operation to change the placement. In this manner, the change operation reception process PS18 is performed.

In this way, when an operation to change the placement of materials and equipment is input by the change operation reception process PS18, change data D17 is generated that indicates the operation content, i.e., the materials and equipment whose placement is to be changed and the positions of the materials and equipment after the change. Then, the CAD data D13, etc. are changed based on the change data D17.

In addition, "table output" may be performed to display each piece of information in a table format or the like. Furthermore, "2D drawing output" may be performed to display blueprints and the like in 2D drawings by converting the CAD data D13 or the like. Furthermore, "information sharing with the site, etc." may be performed to transmit and receive each piece of information to and from a mobile terminal or the like. Furthermore, "input and output of production information" may be performed to transmit and receive each piece of information used in the construction of a building.

Calculation result data D18 shows the results of calculating the range within which a penetrating object can penetrate or avoid a beam.

The placement data D19 is data such as a plan view showing the installation positions of beams, etc. and the routes of penetrating objects, etc.

Beam data D20 indicates various setting values for the beam. Details of beam data D20 will be described later.

The penetrating object data D21 indicates various setting values for objects that will become penetrating objects. Details of the penetrating object data D21 will be described later.

As described above, it is assumed below that after a BIM model or the like has been constructed, the user UR checks the interior of the building with the goggles 12. This type of work may be performed at any time. During this work, the installation is assisted by instructing the installation location of materials and equipment (including instructions to change the location when it is set in advance).

<Overall processing example>
FIG. 7 is a flowchart showing an example of the overall process in the first embodiment.

<Example of beam data input> (Step S01)
In step S01, the design device inputs beam data.

<Example of penetrating object data input> (Step S02)
In step S02, the design device inputs the penetrating object data.

<Calculation example of first passable range> (Step S03)
In step S03, the design device calculates a first passable range.

The first passable range is the range within one beam where a diameter is sufficient for an object to penetrate the beam while meeting certain regulations. Specifically, the first passable range is calculated using the formula shown in "Reinforced Concrete Structure Bar Arrangement Standards (authored by the Construction Ministry Secretariat, Government Maintenance Department, published by the Construction Association in 1977)" etc.

For example, steps S01 to S03 are input and output using a GUI (Graphical User Interface) such as the one shown below.

<Example of input and calculation result of first passable range>
For example, "beam type", which is an example of beam data, is set on the input/output screen shown below. Since the input, calculation, and output differ depending on whether the "beam type" is steel (indicated as "S" in the "beam type" in the figure), whether the "beam type" is reinforced concrete (indicated as "RC" in the "beam type" in the figure), or whether the "beam type" is steel-framed reinforced concrete (indicated as "SRC" in the "beam type" in the figure), the input/output screens will be explained separately below.

Figure 8 is a diagram (part 1) showing an example of an input/output screen. The input/output screen shown is an example of an input/output screen when the "beam type" is steel frame. For example, when beam data and penetrating object data are input on the input/output screen as shown in the figure, the first passable range is calculated and the calculation result is output.

An operation to select "calculate the adaptation level" or "calculate only the effective range" is input to the calculation method input section IN11. Specifically, when "calculate the adaptation level" is selected, the range through which the penetrating object can pass is calculated based on the set values of the purpose, size, and fireproof coating, etc., input on the input/output screen shown in the figure. On the other hand, when "calculate only the effective range" is selected, the range through which the penetrating object can pass is calculated without considering the outer diameter, insulation thickness, and gaps, etc., of the penetrating object when input on the input/output screen shown in the figure. Therefore, in the case of "calculate only the effective range", the outer diameter, insulation thickness, and gaps, etc. of the penetrating object are not considered, so penetrating object data is not required. On the other hand, if penetrating object data is also used, the design device can also calculate values such as "required opening diameter" as shown in FIG. 8 or FIG. 9. With such values, the design device can also calculate whether the passing diameter can be secured. The "required opening diameter" and "passing diameter" will be described later.

Settings such as "pipe type," "application," and "nominal diameter" are input to the pipe type selection input section IN12. Specifically, the type of penetrating object is input to "pipe type." In the example shown, either "pipe" or "duct" is selected for "pipe type."

In "Use", the use of the target penetrating object is selected. For example, as shown in the figure, "Use" is entered as "Pipe" and the type of object that flows through the selected pipe.

The size of the pipe is entered in "nominal diameter." Therefore, "nominal diameter" is the setting value entered when "pipe type" is "pipe." Note that in this example, if "pipe type" is "duct," "size" will be the setting value instead of "nominal diameter."

Setting values such as "beam type" are input to the beam type selection input section IN13. As described above, in this example, when "beam type" is selected as "S", the input/output screen shown in the figure is displayed. On the other hand, when "beam type" is selected as "SRC" or "RC", the input/output screen switches to the input/output screen shown in FIG. 9.

The fireproof coating method input section IN14 receives set values such as the "top floor," "target floor," "coating," and "[t2] fireproof coating thickness (beam body)" of the target building.

In "Top Floor", the top floor of the target building is entered, i.e., how many floors the target building has.

In "Target floor", enter the floor on which the penetrating object will be installed.

In "Covering", the type of covering to be attached to the penetrating object is entered. Specifically, "Covering" is selected from products such as "Sprayed Rock Wool (registered trademark)", "Makibee (registered trademark)", "Suributasuke (registered trademark)" and "Pylon Barrier (trademark)".

In "[t2] Fireproof coating thickness (beam body)," the calculation result of the coating thickness that satisfies the fire resistance standard time is output based on the set values of "top floor," "target floor," and "coating." For example, if "coating" is set to "Makibee (registered trademark)" and the "fire resistance standard time is 1 hour," ""[t2] Fireproof coating thickness (beam body)" will be output as "20 millimeters." Similarly, if the "fire resistance standard time is 2 hours," ""[t2] Fireproof coating thickness (beam body)" will be output as "40 millimeters." Furthermore, if the "fire resistance standard time is 3 hours," ""[t2] Fireproof coating thickness (beam body)" will be output as "65 millimeters."

On the other hand, if "Covering" is set to something other than "Makibee (registered trademark)" and "Fire resistance reference time is 1 hour", then "[t2] Fire resistance coating thickness (beam body)" will be output as, for example, "25 millimeters". Similarly, if "Fire resistance reference time is 2 hours", then "[t2] Fire resistance coating thickness (beam body)" will be output as, for example, "45 millimeters". Furthermore, if "Fire resistance reference time is 3 hours", then "[t2] Fire resistance coating thickness (beam body)" will be output as, for example, "60 millimeters".

The penetration dimension display section IN15 displays the "[K] outer diameter," "[A] insulation thickness," "[R] gap," "[t1] fireproof coating thickness (opening)," and "[H] required opening diameter," etc.

In "[K] Outer diameter", a value indicating the outer diameter of the penetrating object corresponding to, for example, the "nominal diameter" or "size" is output.

For "[A] Insulation thickness", a value is output based on the "purpose" and "nominal diameter" (or "size") input to the pipe type selection input section IN12. For example, the value is obtained from a database that serves as a pre-set insulation thickness master, implementation guidelines, etc.

For example, a preset value is displayed for "[R] Gap." Specifically, the initial value is set to "25 millimeters."

For "[t1] Fireproof coating thickness (opening)", a value is output based on the type of "coating" input to the fireproof coating method input unit IN14. In other words, a value corresponding to the type of "coating" is obtained from a pre-set database, etc., and displayed in "[t1] Fireproof coating thickness (opening)".

In the "[H] required opening diameter" field, a value calculated based on the "[K] outer diameter," "[A] insulation thickness," "[R] gap," and "[t1] fireproof coating thickness (opening)" is output. For example, the value output in the "[H] required opening diameter" field is calculated as "[K] + 2 x ([A] + [R] + [t1])." Below, we explain using an example where the hole diameter indicated in the "[H] required opening diameter" is the minimum required to allow a penetrating object to pass through.

The first passable range display section IN16 displays the calculation results of the first passable range. Specifically, in the illustrated example, "1/3" of "Beam depth [D]" (shown as "0.333" in decimal in the figure) is the "opening diameter standard," that is, the upper limit of the size of the hole that may be drilled in the beam according to the regulations to allow the penetrating object (including the above-mentioned coating and voids, etc.) to pass through.

In addition, in the illustrated example, the range set as the "[L1] edge clearance dimension" is set so that the penetrating object does not pass through. Therefore, in the illustrated example, the range set as the "[L1] edge clearance dimension" does not include the first passable range, and the first passable range is calculated so as to ensure the range set as the "[L1] edge clearance dimension." The "[L1] edge clearance dimension" is set, for example, to the "edge clearance standard."

The illustrated example is a case where the "[H] required opening diameter" satisfies the "opening diameter standard." Therefore, the first passable range display unit IN16 displays the "penetration range," which is an example of the first passable range.

In the illustrated example, the "penetration range" in which the upper "L1 edge clearance dimension" can be secured is displayed on the left side of the figure, i.e., the upper limit of the "penetration range." On the other hand, the "penetration range" in which the lower "L1 edge clearance dimension" can be secured is displayed on the right side of the figure, i.e., the lower limit of the "penetration range."

Figure 9 is a diagram (part 2) showing an example of an input/output screen. The input/output screen shown is an example of the screen that is displayed when "Beam type" is selected as "SRC" or "RC." Below, we will mainly explain the differences from the input/output screen shown in Figure 8, and omit redundant explanations.

In the pipe type selection input section IN12, settings such as "pipe type," "use," and "nominal diameter" are input, just as when "beam type" is selected as "S." The illustrated example shows an example where "duct" is selected as "pipe type."

In the beam type selection input section IN13, "SRC" or "RC" is input as "Beam type." The following will explain the case where "RC" is selected.

In the fireproof coating method input section IN14, "Covering" and "[t2] Fireproof coating thickness (beam body)" are grayed out to prevent input and output when "Beam type" is "SRC" or "RC."

In the "[H] required opening diameter" field, a value calculated based on the "[K] outer diameter," "[A] insulation thickness," and "[R] gap" is output. For example, the value output in the "[H] required opening diameter" field is calculated as "[K] + 2 x ([A] + [R])." Below, we explain an example in which a hole with the diameter indicated in the "[H] required opening diameter" is the minimum required to allow a penetrating object to pass through.

The first passable range display section IN16 displays the calculation results of the first passable range, etc. Specifically, just as when "Beam type" is selected as "S," in the illustrated example, "1/3" of "[D] Beam depth" is the "Aperture diameter standard," that is, the upper limit of the size of the hole that may be drilled in the beam according to the regulations to allow the penetrating object (including the above-mentioned coating and voids, etc.) to pass through.

As shown in Figures 8 and 9, the "adaptation level" is the range in which the "required opening diameter [H]" can be adapted to the position of the center of the penetrating object (which is the center of the required opening diameter) that can be ensured under the regulations. As shown in the figures, the "adaptation level" is determined, for example, by the upper and lower limits in the height direction (which is the direction of the beam height).

<Examples of piping and beams>
FIG. 10 is a diagram showing an example of beam arrangement and piping route. Hereinafter, an example of beam arrangement and piping as shown in the figure will be described. Specifically, in this example, a first beam B1 (sometimes referred to as "beam 1"), a second beam B2 (sometimes referred to as "beam 2"), a third beam B3 (sometimes referred to as "beam 3"), a fourth beam B4 (sometimes referred to as "beam 4"), and a fifth beam B5 (sometimes referred to as "beam 5") are arranged as shown in the figure. In order to specify such arrangement and route, position information (including height direction) and the like are input in the form of a design drawing or the like to the beam data and the penetrating object data.

In this example, for this beam arrangement, the piping PL passes through the route shown in the figure. Therefore, to follow the route shown in the figure, the piping PL needs to pass through or avoid the first beam B1, the second beam B2, the third beam B3, the fourth beam B4, and the fifth beam B5.

First, when steps S01 and S02 are performed, the arrangement, route of the penetrating object, characteristics of each beam and characteristics of each penetrating object, etc. are input for the beams and penetrating objects as shown in the figure. Therefore, for example, the first passable range of each is calculated by step S03, such as the "penetration range" in FIG. 8 or FIG. 9. Next, steps S04 and S05 are performed as follows.

<Example of calculating the second passable range based on a plurality of first passable ranges> (Step S04)
In step S04, the design device calculates a second passable range based on the multiple first passable ranges.

<Display example of second passable range> (Step S05)
In step S05, the design device displays the second passable range. An example of displaying the second passable range will be described below using the example shown in the figure. First, it is assumed that the beams and piping are as follows.

For example, in the case of pipes and beams as shown in Figure 10, the calculation results of step S04 are displayed in step S05 as follows:

<Example of passable range display>
11 is a diagram (part 1) showing a display example of a passable range. The illustrated first calculation result display screen CR1 is an example of a display screen that displays the second passable range based on the calculation result data.

The illustrated example is a case where two types of second passable ranges (hereinafter, the two illustrated second passable ranges are referred to as "first pattern PTN1" and "second pattern PTN2") are calculated based on the calculation results of the first passable range.

For example, on the first calculation result display screen CR1, the second passable range of the first pattern PTN1 is displayed as the second effective range EN22, etc. On the other hand, the second passable range of the second pattern PTN2 is displayed as the first effective range EN21, etc.

The first pattern PTN1 is a pattern in which the piping penetrates the first beam B1, the third beam B3, and the fifth beam B5. Such a result is displayed as "Beam Penetration Pattern" as "Beam 1," "Beam 3," and "Beam 5."

Furthermore, the first pattern PTN1 is a pattern in which the piping avoids the second beam B2 and the fourth beam B4. In the illustrated example, the piping passes under the second beam B2 and the fourth beam B4. Such a result is displayed as "under beam 2" and "under beam 4" in the "beam penetration pattern". Therefore, since the piping does not penetrate the second beam B2 and the fourth beam B4, the calculation result is that three of the five beams have a penetration aperture. Such a result is displayed as "3" in the "number of sleeves". Hereinafter, the number of sleeves indicates the number of penetrating holes.

In the illustrated example, the first beam B1 and the fifth beam B5 are the same beam (such as when the beam conditions indicated by the beam data, such as "beam type" and "pipe type", are all the same), so they are displayed together in a single display. Similarly, the illustrated example is an example in which the second beam B2 and the fourth beam B4 are displayed together in a single display.

In this example, the second passable range is calculated based on the first passable range of the first beam B1 and the fifth beam B5 (hereinafter referred to as the "eleventh passable range EN11"), the first passable range of the second beam B2 and the fourth beam B4 (hereinafter referred to as the "twelfth passable range EN12"), and the first passable range of the third beam B3 (hereinafter referred to as the "thirteenth passable range EN13"), which are calculated in advance.

Specifically, the second passable range is found by calculating the "AND" of the eleventh passable range EN11, the twelfth passable range EN12, and the thirteenth passable range EN13. In other words, from the calculation results of each first passable range, the range through which all beams can pass is extracted as the second passable range. This type of calculation is often cumbersome to perform manually when there are many beams. Therefore, if the design device can display such calculation results, the user can easily know the second passable range.

The illustrated example is also an example in which the second passable range is displayed numerically. The second passable range is displayed, for example, as numerical values such as an upper limit value and a lower limit value. The first pattern PTN1 is a range with a lower limit value of "3156" (an example of a so-called level display). On the other hand, the first pattern PTN1 is a range with an upper limit value of "3470". In this example, such upper and lower limits are displayed as "FL+3470" and "FL+3156" above the display showing the second effective range EN22.

In addition, the upper and lower limits are displayed in the "Effective Range" section as "3156-3470." In the illustrated example, the number in parentheses indicates the length of the second passable range (the value corresponds to the difference between the upper and lower limits).

Furthermore, in the illustrated example, a diameter (hereinafter referred to as the "passing diameter") that allows the penetrating object to pass while satisfying certain rules is calculated. Then, the design device extracts a second passable range from the second passable range in which the passing diameter can be secured.

First, in the example where the "beam type" is "S," the state in which the specified regulations are met is when "[K] outer diameter," "[A] insulation thickness," "[R] gap," and "[t1] fireproof coating thickness (opening)" are ensured. In other words, if the diameter of "[H] required opening diameter" is ensured, the penetrating object will be fitted with a coating or other covering and will be in a state in which the regulations of the Building Standards Act and other laws are met.

Therefore, the passage diameter is a diameter that can ensure the "required opening diameter [H]".

In this example, the design device determines whether the first effective range EN21 and the second effective range EN22 are ranges in which the passing diameter can be secured. In this example, the passing diameter is "300". First, the first effective range EN21 is "48", so the passing diameter cannot be secured. On the other hand, the second effective range EN22 is "314", so the passing diameter can be secured. The design device indicates such a determination result by, for example, the penetrating object mark OUT1. As shown in the figure, the penetrating object mark OUT1 is displayed in the second effective range EN22. On the other hand, the penetrating object mark OUT1 is not displayed in the first effective range EN21.

In this example, the result of the determination as to whether the passing diameter is within the range that can be secured is also displayed on the "Pipe Level (Core)".

The "piping level (core)" indicates the range in which the center of the penetrating object, i.e., the "core," can be obtained when passing through each second passable range (in this example, this number is also expressed as a level).

Specifically, since the first pattern PTN1 can be secured, the range in which the passing diameter can be secured to pass through the second passable range (an example shown with upper and lower limits) is displayed, such as "3235-3391." On the other hand, since the second pattern PTN2 cannot be secured, "Cannot be selected" is displayed.

In this way, when the second passable ranges in which the passing diameter can be secured are extracted, the user can know which of the second passable ranges is the range in which the passing diameter can be secured.

The illustrated example is an example in which an error display OUT2 is displayed to inform the user of the beams that do not meet the specified criteria and the details of the criteria that have not been met. In this example, the second beam B2 and the fourth beam B4 are beams that do not meet the criteria to allow the penetrating object to pass through.

Furthermore, as shown in the figure, the indications showing the second beam B2 and the fourth beam B4 are displayed in a different color from the beams that meet the other criteria. Also, this example is an example in which the criterion is whether the "required opening diameter" is "1/3" or more of the beam depth excluding the edge clearance.

With this display, the user can easily see which beams do not meet the specified criteria and what criteria have not been met.

In addition, the illustrated example displays the beam depth (indicated in the figure as "1200D", "485D" and "1100D") and maximum opening diameter (indicated in the figure as "Maximum opening diameter: 700", "Maximum opening diameter: 125" and "Maximum opening diameter: 600") at the top of each beam.

Based on the error display OUT2 as shown in the figure, if the second beam B2 and the fourth beam B4 are changed to beams that can ensure the passing diameter, for example, the following display will appear.

Figure 12 is a diagram (part 2) showing an example of the display of the passable range. Compared to Figure 11, the second calculation result display screen CR2 differs in that the second beam B2 and the fourth beam B4 are changed. As a result of this change, in the calculation result display section OUT3, the passing diameter can be secured even in the second pattern PTN2, so that the penetrating object mark OUT21 and the penetrating object mark OUT22 are displayed in both the first pattern PTN1 and the second pattern PTN2.

In this way, for example, by changing from FIG. 11 to FIG. 12, i.e., by changing the second beam B2 and the fourth beam B4, the second passable range can ensure the passable diameter for both the first pattern PTN1 and the second pattern PTN2.

When the first pattern PTN1 is selected, the screen will change to show something like the one below.

Figure 13 is a diagram showing an example of displaying the upper and lower limit beams in the first pattern. The example shown is an example showing the calculation results of the first pattern PTN1 in a plan view from among the calculation results shown in Figure 12 for the beam combination and piping route shown in Figure 10.

As shown in the figure, the design device distinguishes and displays the upper limit beam (the beam indicated by the first pattern upper limit mark OUT25 in FIG. 12), the lower limit beam (the beam indicated by the first pattern lower limit mark OUT26 in FIG. 12), and other beams in the calculation results of the first pattern PTN1 shown in FIG. 12. In the example shown in the figure, the method of distinguishing and displaying the beams is by color coding.

In the illustrated example, the lower limit beam is the third beam B3. In this example, the lower limit beam is shown in the third color C3.

Furthermore, in the illustrated example, the upper limit beams are the second beam B2 and the fourth beam B4. In this example, the upper limit beams are shown in the second color C2.

In the illustrated example, the beams that are neither the upper limit nor the lower limit are the first beam B1 and the fifth beam B5. This example shows the beams that are neither the upper limit nor the lower limit in the first color C1.

As described above, the design device displays three types of beams, the upper limit beam, the lower limit beam, and other beams, distinguished by three colors. In this way, when the upper limit beam, the lower limit beam, and other beams are displayed distinguished by color or the like, the user can check on the plan view which beams are the upper limit beam, the lower limit beam, and other beams.

In addition, the illustrated example shows the locations where the pipe PL avoids the beams (hereinafter simply referred to as "avoidance locations UN") with hidden lines when the pipe PL avoids passing under the beams. Specifically, as shown in FIG. 12, in the calculation results for the first pattern PTN1, the pipe PL avoids passing under the second beam B2 and the fourth beam B4. Therefore, the illustrated example shows the intersections of the pipe PL and the second beam B2 and the intersections of the pipe PL and the fourth beam B4 as the avoidance locations UN. Such avoidance locations UN are displayed, for example, as shown in the figure, so that the line indicating the route is temporarily interrupted. With such a display, the user can easily know the locations where the pipe PL avoids passing under the beams.

When piping PL passes under beams, the piping PL may be exposed on the floor below. This may be undesirable from a design perspective. Therefore, users may want to know where the piping PL can avoid passing under the beams. If a display like the one shown in the figure can be displayed, users can easily check whether there are any problems from a design perspective.

For example, when the second pattern PTN2 is selected, the screen will change to show the following screen.

Figure 14 is a diagram showing an example of displaying upper and lower limit beams in the second pattern. The display shown in the figure distinguishes between the upper limit beam (the beam shown by the second pattern upper limit mark OUT23 in Figure 12), the lower limit beam (the beam shown by the second pattern lower limit mark OUT24 in Figure 12), and other beams in the calculation results of the second pattern PTN2 shown in Figure 12. Below, as in Figure 13, an example is shown in which the upper limit beam, the lower limit beam, and other beams are displayed in different colors (as in Figure 13, the lower limit beam is displayed in the third color C3. The upper limit beam is displayed in the second color C2. And the beams that are neither the upper limit nor the lower limit are displayed in the first color C1).

That is, compared to FIG. 13, the upper limit beam, the lower limit beam, and other beams are different from the first pattern PTN1. Therefore, compared to FIG. 13, the illustrated example has different beams indicated by the first color C1, the second color C2, and the third color C3.

Also, compared to Figure 13, the illustrated example differs in that there is no avoidance location UN. This corresponds to the fact that, as shown in Figure 12, the second pattern PTN2 is a calculation result in which there is no location where a penetrating object can pass through, avoiding the area under the beam.

In this way, when the display switches depending on the pattern, the user can easily know which beams are the upper limit, which beams are the lower limit, and which are not, for each pattern. Also, when the display switches depending on the pattern, the user can easily know whether or not there are any avoidance points UN for each pattern.

In addition, if you change the beam data or penetrating object data, the design device will perform recalculation as follows:

Figure 15 is a diagram showing an example of recalculation. First, in the figure, assume that the setting values are as shown in the figure above (the left screen of the two screens indicated as "Before change" in the figure). Note that the following example will be explained using an example in which the setting values etc. are entered on the input/output screen shown in Figure 8, i.e., the "Beam type" is "S". The screen showing the calculation results calculated using the "Before change" setting values is the 31st calculation result display screen CR31.

Next, change the setting value from the figure above to the figure below (the left drawing of the two screens labeled "After Change" in the figure). Below, we will explain an example of changing the type of "Covering" in the "Fire Resistant Covering Method" from "Covering A" shown in "Before Change" to "Covering B" shown in "After Change" as shown in the figure.

When changing from "Covering A" "before the change" to "Covering B" "after the change", the calculation is re-done as shown in the figure, and the value of "[t1] Fireproof Covering Thickness (Opening)" changes from "6" to "12".

Furthermore, when the "[t1] fireproof coating thickness (opening)" is changed, the "[H] required opening diameter" calculated based on the "[t1] fireproof coating thickness (opening)" is recalculated. As a result of this recalculation, in the example shown, the "[H] required opening diameter" is "158" "before the change," whereas the "[H] required opening diameter" is "170" "after the change." In other words, this is an example of a case where the change results in a larger passage diameter "after the change" than "before the change." The calculation results are also reflected in real time in the display on the right.

Specifically, first, the 31st calculation result display screen CR31 displays two second passable ranges, the 211th effective range EN211 and the 212th effective range EN212, as calculation results. Then, under the conditions shown in the above figure, the 211th effective range EN211 and the 212th effective range EN212 are both second passable ranges in which the passing diameter can be secured. Therefore, "before the change", a penetrating object mark is displayed in both the 211th effective range EN211 and the 212th effective range EN212. In addition, to show that the "piping level (core)" is also both a second passable range in which the passing diameter can be secured, the numerical values of the range through which the core can pass are displayed, such as "3235-3276" and "3660-3665".

On the other hand, even under the "after change" conditions, there are two second passable ranges, the 221st effective range EN221 and the 222nd effective range EN222. Therefore, the 32nd calculation result display screen CR32 displays the two second passable ranges, the 221st effective range EN221 and the 222nd effective range EN222, as calculation results. In this example, the passable diameter is larger "after change" than "before change". Therefore, it is assumed that the passable diameter cannot be secured in the 221st effective range EN221. On the other hand, it is assumed that the 222nd effective range EN222 is a second passable range in which a passable diameter can be secured, similar to the 212th effective range EN212 "before change".

Therefore, after the change, a penetrating object mark will be displayed in the 222nd effective range EN222. In addition, the "piping level (core)" will also show the range through which the core can pass, such as "3247-3270", to indicate that the 222nd effective range EN222 is the second passable range where the passing diameter can be secured.

On the other hand, the 221st effective range EN221 does not display the penetrating object mark because the passing diameter cannot be secured. Also, the "Pipe level (core)" is displayed as "Cannot be selected" to indicate that it is not the second passable range where the passing diameter can be secured.

In this way, when recalculation is performed, the user can easily try out various conditions. Also, as shown in the figure, depending on the setting value being changed, even if the passing diameter was secured before the change, it may be necessary to check whether the passing diameter can be secured after the change as well. In such cases, the design device updates the screen displaying the calculation results so as to reflect the changed setting value in real time. In this way, the user can easily check whether the passing diameter can be secured even after the change.

<Example of saving reference data>
The above-mentioned calculation results or recalculation results are stored as data, for example, as follows.

Figure 16 is a diagram showing an example of saving a calculated or recalculated pattern. Below, an example will be explained in which the beam and route calculations shown in Figure 10 have been performed. For example, when the "Save" button is pressed on a screen that displays the calculation results as in Figure 12, the calculation results are saved.

The illustrated example is an example in which the calculation results, the setting values and route that are the premise of the calculation, etc. are saved. Specifically, for example, as illustrated, the route to be saved is drawn by indicating it with the auxiliary line RF. Then, the calculation result data indicating the calculation results of the route that becomes the auxiliary line RF (for example, the results shown in Figures 12 and 13) etc. is saved in the attributes.

In this way, by saving calculation results, setting values, routes, etc. (hereinafter referred to as "reference data"), the user can later view the saved content for reference. In design, various setting values, etc. may be tried out. In such cases, the task of repeatedly inputting similar setting values occurs. On the other hand, if reference data is saved, the task of inputting setting values can be reduced by reading the reference data and reflecting it in the setting values. Also, in this way, the results of various trials can often be used as reference later. Therefore, being able to save reference data makes design, etc. easier for the user.

<Simulation example>
For example, the design device displays the change in the second passable range depending on the presence or absence of a beam by the following simulation.

Figure 17 is a diagram showing an example of a simulation result before the change. For example, assume that there are five beams, a first beam B1, a second beam B2, a third beam B3, a fourth beam B4, and a fifth beam B5, as shown in the figure (as shown, the first beam B1 and the fifth beam B5 are the same type of beam. Therefore, on the screen shown in the figure, the first beam B1 and the fifth beam B5 are displayed together as one), and the second passable range is calculated. Then, assume that the calculation result is as shown in the 41st calculation result display screen CR41.

Specifically, as shown in the figure, two second passable ranges, the 231st effective range EN231 and the 232nd effective range EN232, are calculated. Then, both the 231st effective range EN231 and the 232nd effective range EN232 are second passable ranges that are narrow and therefore cannot ensure a passing diameter. Therefore, in this example, the penetrating object mark is not displayed in either the 231st effective range EN231 or the 232nd effective range EN232.

Furthermore, the fact that neither the 231st effective range EN231 nor the 232nd effective range EN232 can secure a passing diameter is displayed as "Penetration not possible" at the "Pipe level (core)".

Therefore, the design device, for example, simulates the case where the fourth beam B4 is not present. For example, when an operation is performed to click on the image showing the fourth beam B4 (hereinafter referred to as the "fourth beam image TB") on the 41st calculation result display screen CR41, the design device performs calculations under conditions excluding the fourth beam B4. As a result, for example, the following is displayed.

Figure 18 is a diagram showing an example of the simulation results after the change. Compared to the case of Figure 17, the 42nd calculation result display screen CR42 differs in that the "Beam penetration pattern" is displayed as "Beam 1 - Beam 2 - Beam 3 - Beam 5". In other words, this calculation result is the calculation result when a calculation is performed using four beams, the first beam B1, the second beam B2, the third beam B3, and the fifth beam B5, excluding the fourth beam B4.

In this case, it would be the case that the fourth beam B4 is removed or the route is changed so that it does not pass through the fourth beam B4.

As shown in the figure, the calculation excludes the fourth beam B4, so the second passable range is calculated to be the 233rd effective range EN233. The 233rd effective range EN233 is wider than the 231st effective range EN231 and the 232nd effective range EN232. In other words, the 233rd effective range EN233 is the second passable range in which the passing diameter can be secured. Furthermore, since the 233rd effective range EN233 is the second passable range in which the passing diameter can be secured, the penetrating object mark OUT4 is displayed.

The fourth beam image TB is displayed in a different color, etc., than that shown in FIG. 17 to indicate that the fourth beam B4 has been excluded.

In this way, the user can see that by removing the fourth beam B4 or by taking a route that does not pass through the fourth beam B4, the second passable range can be achieved in which the passing diameter can be secured.

<Example of recalculation using saved routes, etc.>
First, it is assumed that beam data and penetrating object data indicating the conditions of the route and beams, etc., as shown below, and calculation result data indicating the calculation results calculated based on these data are stored.

Figure 19 is a diagram showing an example of a saved route. The example shown is an example in which the calculation results (assuming there is one pattern) calculated for the route indicated by the auxiliary line RF are saved. In addition, in the example shown, a reference value RF1 is displayed. Specifically, the reference value RF1 indicates the result of the "piping level (core)". In other words, the reference value RF1 indicates that the calculation results for the illustrated route include a second passable range in which the passing diameter can be ensured, within the range of "FL + 3660" to "FL + 3665". And, for the data saved in this way, the following calculation results are saved:

Figure 20 shows an example of saved calculation results, etc. As shown in the figure, in the pattern where "No" is "2", the "Pipe Level (Core)" is "3660 to 3665", and the pattern where "No" is "2" is the pattern indicated by reference value RF1.

When "latest display" is pressed on the screen shown in the figure, the design device performs recalculation. Specifically, the design device newly reads the latest data (hereinafter simply referred to as "latest data") such as design data, and reflects it in the setting values, etc. Next, the design device recalculates the first passable range and second passable range, etc., based on the new design values, etc.

Design data, etc. may differ between the time when the data was saved and the current time. Therefore, even for a saved route, the calculation results may change from the time when the data was saved due to design changes such as changes to the beam material or placement. Therefore, the design device reads the latest data, etc. and performs recalculation. In this way, the calculation results that reflect the design changes, etc. can be easily known.

For example, the design device compares the recalculation result between the previous calculation result (i.e., the calculation result at the time of saving) and the latest calculation result (i.e., the calculation result that reflects the setting values, etc. based on the latest data, etc.). If the comparison shows that the previous calculation result and the latest calculation result match, the design device displays a dialog message, etc. to the user that the calculation result has not changed since it was saved.

On the other hand, as a result of recalculation, the calculation result of the previous value may differ from the latest calculation result. For example, the design device displays the calculation result of the previous value and the latest calculation result as follows:

Figure 21 is a diagram showing an example of the display of the latest calculation results, etc. In other words, the latest calculation results are assumed to be the calculation results shown in the figure. Then, when the "Display previous value" button is pressed on the screen shown in the figure, the design device switches to a screen showing the calculation results of the previous value.

Figure 22 is a diagram showing an example of the display of the calculation results of the previous value, etc. In other words, it is assumed that the calculation results of the previous value are the calculation results as shown in the figure. Then, when the "latest display" button is pressed on the screen shown in the figure, the design device switches to a screen showing the latest calculation results.

In this example, the positions of "Beam 2" and "Beam 4" (Beam 2 and Beam 4 are assumed to be the same type of beam) have been changed. Specifically, in the previous calculation result, there is a second passable range in which a penetrating object can pass under "Beam 2" and "Beam 4". On the other hand, in the latest calculation result, there is no case in which a penetrating object can pass under "Beam 2" and "Beam 4", and the second passable range is a range that penetrates all of "Beam 2" and "Beam 4".

For example, if the user presses "Show previous value" and "Show latest value" in succession to switch the display screen, the user can easily find what has changed. In this way, the calculation result at the time of saving is compared with the latest calculation result, and the comparison result is displayed, allowing the user to easily see what has changed since the time of saving.

<Example of adding or overwriting>
First, assume that one pattern is saved as shown in Fig. 19. In this state, when the "Save" button is pressed on the screen displaying the calculation results in Fig. 21 or the like, the design device saves the calculation results of a new pattern.

In such a case, an operation to select "add" or "overwrite" is performed. For example, when the data is saved as shown in FIG. 19, if the calculation result of the pattern shown in FIG. 21 is saved as "add", it will be saved as follows:

Figure 23 shows an example of saving to add calculation results, etc. Compared to Figure 19, the example shown differs in that there are two saved patterns.

The reference value RF1 indicates that one pattern is stored, whereas the reference value RF2 indicates that two patterns are stored.

On the other hand, in the case of "overwrite," the data stored in FIG. 19 is overwritten, and the data is saved so that the calculation result has the pattern shown in FIG. 21.

<Functional configuration example>
24 is a functional block diagram showing an example of a functional configuration in the first embodiment. For example, the design system 10 has a functional configuration including a beam data input unit 10F1, a penetrating object data input unit 10F2, a calculation unit 10F3, a calculation result data generation unit 10F4, and a display unit 10F5.

The beam data input means 10F1 performs a beam data input procedure for inputting beam data D20 indicating setting values and the like for the beam. For example, the beam data input means 10F1 is realized by an interface 11H3, etc.

The penetrating object data input means 10F2 performs a penetrating object data input procedure for inputting penetrating object data D21 indicating settings and the like for the penetrating object. For example, the penetrating object data input means 10F2 is realized by an interface 11H3 and the like.

The calculation means 10F3 performs a calculation procedure to calculate the first passable range EN1 in which each beam can be penetrated or avoided based on the beam data D20 and the penetrating object data D21, etc. For example, the calculation means 10F3 is realized by the CPU 11H1, etc.

The calculation result data generating means 10F4 performs a calculation result data generating procedure to generate calculation result data D18 indicating a second passable range EN2 through which any of the multiple beams can pass, based on each of the first passable ranges EN1 calculated by the calculation means 10F3. For example, the calculation result data generating means 10F4 is realized by the CPU 11H1, etc.

The display means 10F5 performs a display procedure to display the second passable range EN2 based on the calculation result data D18. For example, the display means 10F5 is realized by the interface 11H3, etc.

When the beam data D20 and the penetrating object data D21 are input as described above, the first passable range EN1 can be calculated, for example, as shown in FIG. 8 or FIG. 9. The first passable range EN1 is then calculated for each beam.

Next, calculation result data D18 is generated based on the first passable range EN1 calculated for each beam. In this way, with the calculation result data D18, it is possible to display the second passable range EN2, for example, as shown in FIG. 12.

By displaying the second passable range EN2, the design device etc. can inform the user of the calculation results, such as the position where the penetrating object can pass based on regulations etc., or whether or not it is possible to pass the penetrating object when passing the penetrating object through multiple beams.

Second Embodiment
The second embodiment is realized, for example, by an apparatus having the same system configuration and hardware configuration as the first embodiment. The following description will focus on the differences from the first embodiment, and will omit descriptions that overlap with the first embodiment.

The second embodiment is a case where support materials are installed when designing the layout of pipes, ducts, etc. (hereinafter sometimes referred to as "objects").

The following describes an example in which an object is supported using two types of support material, a first support member and a second support member.

The first support member is, for example, a combination of an insert (sometimes called an "insert metal fitting") and a mounting metal fitting. Hereinafter, it is assumed that the insert is embedded in the structure of the building at the position where the first support member is to be installed, and then the mounting metal fitting is inserted into the insert. In the following explanation, the combination of the insert and the mounting metal fitting is simply referred to as an "insert".

The second support member is a so-called "earthquake-resistant support member" that is installed to make the object earthquake-resistant. Specific examples of earthquake-resistant support members will be described later.

The first support members are installed with spacing etc. determined according to a predetermined rule (hereinafter referred to as the "first rule").

On the other hand, the spacing etc. for installing the second support members is determined by rules (hereinafter referred to as the "second rules") that are different from the first rules.

Specific examples of the first and second rules will be described later.

<Overall processing example>
For example, the design device determines the positions at which the first support member and the second support member are to be installed by the following overall processing.

Figure 25 is a flowchart showing an example of the overall processing in the second embodiment.

<Example of input of object data> (Step S11)
In step S11, the design device inputs object data.

The object data is data that indicates, for example, the weight and size of the object. The input values that are input in advance into the object data are determined by the contents of the first rule and the second rule. In other words, the object data is data that enables calculation of the installation interval, etc. based on the first rule and the second rule.

Specifically, when using the rules of the "Guidelines for Earthquake-Resistant Design and Construction of Building Facilities, 2014 Edition," calculation of installation intervals requires input values such as the type of object (for example, piping, square ducts, round ducts, valves, metal ducts, electric pipes, bus ducts, electric wiring, or cable racks) and the weight of the object. Also, if the object is a water pipe, drain pipe, or brine pipe, the weight when full of water is the input value.

Therefore, when the first and second support members are installed based on the above rules, data such as an object master is input that indicates input values that can identify the type and weight of the object to be supported by the first and second support members.

<Example of input of first support member data> (Step S12)
In step S12, the design device inputs first support member data.

The first support member data is data such as an insert master that can identify the type of the first support member. Details of the insert master will be described later.

<Example of input of second support member data> (Step S13)
In step S13, the design device inputs second support member data.

The second support member data is data such as a seismic support member master that can identify the type of the second support member, etc. Details of the seismic support member master will be described later.

<Example of input of installation range> (Step S14)
In step S14, the design device inputs the installation range. An example of inputting the installation range will be described later.

<Example of installation of first support member based on first rule> (Step S15)
In step S15, the design device places the first support member based on the first rule. An example of determining the placement position of the first support member will be described later.

<Example of Installation of Second Support Member Based on Second Rule> (Step S16)
In step S16, the design device places the second support member based on the second rule. An example of determining the placement position of the second support member will be described later.

As described above, when multiple support members are installed, different rules are applied to each support member. Therefore, even if a support member needs to be installed according to a single rule, it may end up being unnecessary when other support members are taken into consideration.

For example, if there is a seismic support member, an insert may not be necessary. In other words, there are many cases where it is not necessary to install two support members in the same position. In such cases, since the seismic support member is installed, the installation of the insert is not necessary, and the insert can be omitted. Specifically, assume that the rule stipulates that inserts are installed at intervals of "2.0 m". On the other hand, assume that the rule stipulates that seismic support members are installed at intervals of "6.0 m". Note that the starting point for calculating the intervals is the same. In such a case, at least the positions of "6.0 m", "12.0 m", and "18.0 m" overlap as positions for installation. In such a case, the installation of the insert can be omitted. Therefore, the number of inserts to be installed can be reduced.

In steps S11 to S16, the following processing is performed, for example:

<Example of installation range input>
26 is a diagram showing an example of inputting the installation range. Below, an example will be described in which a pipe as shown in the figure is the target. Furthermore, in the following example, first, a first support member is installed in a portion of the entire pipe as shown in the figure that is specified by the installation range.

As shown in the figure, the installation range RG is input by, for example, specifying the target range with the cursor. Specifically, first, the position of the first point PT1 is specified. Then, the position of the second point PT2 is specified. In this way, the rectangular range with the first point PT1 and the second point PT2 as diagonals becomes the installation range RG. Then, if there is an object such as a pipe within the range specified in the installation range RG, it is recognized as a target for installing the support member.

As shown in the figure, the operation of inputting the installation range RG determines the point where the installation of the support members begins (hereinafter referred to as the "starting point") and the route along which the support members are to be installed. Specifically, the starting point is set, for example, as follows. Then, from the starting point, for example, the earthquake-resistant support members are installed as follows.

<Example of earthquake-resistant support member installation>
27 is a diagram showing an example of setting the starting point. For example, the starting point is set at the intersection of the side of the rectangle indicating the installation range RG and the piping. Therefore, in the illustrated example, two points, the first starting point PTS1 and the second starting point PTS2, are set as the starting points.

For example, if the first support member is placed with the first starting point PTS1 as the starting point, the display will be as shown in the figure.

In this example, the first support members are installed from the first starting point PTS1 to the piping PI at intervals determined by a predetermined rule (hereinafter, the interval is assumed to be "6.0 m"). For example, the interval from the first starting point PTS1 to the earthquake-resistant support member 2P1 is "6.0 m", as shown by the interval display DS1. In this way, the earthquake-resistant support members 2P1 are basically installed every "6.0 m". In this example, the earthquake-resistant support members are also installed at intervals of "6.0 m" between the earthquake-resistant support members 2P1 and 2P2, as shown by the interval display DS2. In this way, the earthquake-resistant support members are installed within the installation range RG.

In addition, in the case of a route that goes from within the installation range RG to outside the range and then returns to within the range (such as the right end part in the figure), only the piping PI that is within the range is included in the calculation.

In addition, if there are support members (hereinafter referred to as "installed support members") already installed in the installation range RG, for example, the design device will delete the installed support members and install new seismic support members.

<Example of installation avoiding areas where installation is not possible>
During installation, the piping PI has some parts, such as the vertical pipe parts, where earthquake-resistant support members etc. cannot be installed. In such cases, the design device installs earthquake-resistant support members by avoiding the vertical pipe parts etc., for example, as follows.

Figure 28 is a diagram (part 1) showing an installation example. For example, in the illustrated installation range RG, the piping PI has a vertical pipe section OB, i.e., a section where an earthquake-resistant support member cannot be installed.

Let us assume that if earthquake-resistant support members are installed at intervals of "6.0 m", earthquake-resistant support member 2P3 will be installed in the vertical pipe section OB. In such a case, earthquake-resistant support member 2P3 will be installed in a location that avoids the vertical pipe section OB, as shown in the figure. In this way, the design device recognizes the vertical pipe section OB, etc., and places earthquake-resistant support member 2P3 while avoiding the vertical pipe section OB, etc.

Even if the earthquake-resistant support member 2P3 is to be installed in the vertical pipe section OB, it is difficult to install the earthquake-resistant support member 2P3 in the vertical pipe section OB in actual construction work. If the earthquake-resistant support member 2P3 is installed in such a section, it is often necessary to reinstall the earthquake-resistant support member 2P3 manually, etc.

In addition, when the installation location of the seismic support member 2P3 is changed in this way, all subsequent seismic support members installed based on the seismic support member 2P3 may have to be reinstalled. Therefore, by positioning the seismic support member 2P3 to avoid the vertical pipe portion OB, the workload of reinstalling the seismic support member 2P3 can be reduced.

<Example of display at branch>
Furthermore, when the pipe PI has a branching portion, for example, the interval is calculated and displayed as follows.

Figure 29 shows an installation example (part 2). For example, we will explain a case where a branch BR is present in the pipe PI in the installation range RG shown in the figure.

In this example, the branch BR creates a distance DISS between the seismic support members 2P7 and 2P9, and a distance DISL between the seismic support members 2P8 and 2P9. The distance DISL is longer than the distance DISS. In such a case, the distance display V5 displays the value of the distance DISL, i.e., the wider distance.

When there is a branch BR, the branch BR results in multiple routes. For this reason, earthquake-resistant support members are installed for each route. Therefore, as shown in the figure, multiple intervals may occur. In such cases, the wider interval is the one that is displayed by the interval display. In many cases, the wider interval exceeds the specified rule and does not satisfy the rule. Therefore, as shown in the figure, by displaying the one that is most likely to not satisfy the rule, the user can easily check whether the specified rule is being satisfied.

<Example of moving the starting point>
The starting point can be specified by an operation. For example, the starting point can be moved as follows:

Figure 30 shows an example of moving the starting point. First, as shown in Figure 27, when the intersection of the side of the rectangle indicating the installation range RG and the piping PI is set as the starting point, the starting point is set to a part such as the third starting point PTS3.

On the other hand, for example, as shown in the figure, there are cases where earthquake-resistant support members, etc., are installed in advance, such as earthquake-resistant support member 2P10. In other words, there are cases where support members such as earthquake-resistant support member 2P10 are taken into consideration when installing the support members in the installation range RG.

In the illustrated example, when earthquake-resistant support members are installed at the third starting point PTS3, the earthquake-resistant support members will be installed at intervals narrower than those stipulated by the specified rules. Installation in this way may result in an unnecessary increase in the number of earthquake-resistant support members.

Therefore, let us assume that the part that satisfies the specified rules (in the figure, it is the part "6.0 m" to the right from earthquake-resistant support member 2P10. Hereinafter, this part will be referred to as the "new starting point PT3". In this way, by moving the starting point and setting new starting point PT3, a support member will be installed from new starting point PT3 to the installation range RG. Also, even though earthquake-resistant support member 2P10 is outside the installation range RG, it will be included in the calculation of the spacing. Specifically, it will be as follows.

Figure 31 is a diagram showing an example of a spacing display. As shown, the spacing display V6 displays the spacing DISF between the "existing earthquake-resistant support material" (a support material that is installed outside the installation range RG and that is installed in advance) and the support material to be installed at the starting point. In this way, if the spacing is calculated taking into account the support material that is installed in advance even if it is outside the installation range RG, the user can reduce the work of calculating the spacing between the "existing earthquake-resistant support material" and the support material to be newly installed, thereby reducing the workload.

<Example of assistance for moving the starting point>
When the starting point is moved to create a new starting point, the design device provides, for example, the following assistance to the operation of specifying the new starting point.

Figure 32 is a diagram showing an example of assistance for moving the starting point. For example, when the installation range RG is input, starting point PT4 is set at intersection point PTS4 as the initial value. This example is an example in which starting point PT4 is moved from the position of intersection point PTS4, and another position is set as the new starting point. For example, when starting point PT4 at intersection point PTS4 is clicked to specify it, starting point PT4 can then be moved by specifying the position that will become the new starting point.

For example, the design device first displays auxiliary lines L2, L3, L4, L5, etc. to assist in moving the starting point.

The auxiliary line L2 is a line segment that coincides with one side of the rectangle that indicates the installation range RG. The intersection of the auxiliary line L2 and the piping PI (indicated as candidate point CRP1 in the figure) becomes one of the candidate points for the new starting point. Below, we will explain an example in which the characteristic point is the intersection of the auxiliary line and the piping.

The auxiliary line L3 is a line segment whose position in the X direction coincides with that of the earthquake-resistant support member 2P11. The intersection of the auxiliary line L3 and the pipe PI (shown as candidate point CRP2 in the figure) becomes one of the candidate points for the new starting point.

The auxiliary line L4 is a line segment whose position in the X direction coincides with that of the earthquake-resistant support member 2P13. The intersection of the auxiliary line L4 and the pipe PI (shown as candidate point CRP3 in the figure) becomes one of the candidate points for the new starting point.

The auxiliary line L5 is a line segment whose position in the X direction coincides with that of the earthquake-resistant support member 2P12. The intersection of the auxiliary line L5 and the pipe PI (shown as candidate point CRP4 in the figure) becomes one of the candidate points for the new starting point.

When the cursor that moves the starting point approaches candidate point CRP1, candidate point CRP2, candidate point CRP3, or candidate point CRP4, the design device assists the cursor to match candidate point CRP1, candidate point CRP2, candidate point CRP3, or candidate point CRP4. Note that the degree of proximity required for assistance is set in advance.

As shown in the figure, for example, users often want to set the new starting point to a position that is aligned in the X-axis direction with earthquake-resistant support members installed on other piping. Therefore, as shown in the figure, by showing positions that are aligned in the X-axis direction with other earthquake-resistant support members using auxiliary lines, users can easily understand the positions of candidate points.

As mentioned above, the user often moves the starting point to a position that is aligned in the X-axis direction with earthquake-resistant support members installed on other pipes, i.e., to a position that is a candidate point in the illustrated example. On the other hand, when using a mouse or the like to specify the position of a candidate point, there are cases where an incorrect position is specified due to an operational error, etc.

Therefore, when the cursor approaches, assistance is provided to align the cursor with candidate point CRP1, candidate point CRP2, candidate point CRP3, or candidate point CRP4, allowing the candidate point to be specified with high accuracy.

If a new starting point is set and earthquake-resistant support members are installed, for example, it will look like this:

Figure 33 is a diagram (part 3) showing an installation example. For example, when compared to Figure 31, the location where the earthquake-resistant support members are installed is different. In this way, by changing the starting point, it is possible to change the location or quantity, etc., of the earthquake-resistant support members.

<Example of operations for selecting an object>
For example, assume that the target object is composed of three pipes as shown below.

Figure 34 is a diagram showing an example of an object composed of multiple pipes. For example, assume that the object is composed of a first pipe PI1, a second pipe PI2, and a third pipe PI3.

And, there may be cases where it is desired to install earthquake-resistant support members only on the first pipe PI1 out of these three pipes. In such a case, for example, when the first pipe PI1 is selected by clicking on the first pipe PI1, the earthquake-resistant support members are placed on the first pipe PI1, while the earthquake-resistant support members are not placed on the second pipe PI2 and the third pipe PI3. Note that the first pipe PI1, the second pipe PI2, and the third pipe PI3 are all within the installation range.

In this way, by being able to select the target objects, it is possible to install earthquake-resistant support members only on targeted pipes, etc., as shown in the figure.

The following will be described using an example in which the first pipe PI1 is the target object. The following example will be used as an example to explain the case in which the first pipe PI1 has an installed support member, for example.

Figure 35 shows an installation example (part 4). As shown in the figure, in this example, earthquake-resistant support members 2P14 and 2P15 have already been installed on the first piping PI1.

Next, a starting point PT5 is set for the position of earthquake-resistant support member 2P15. Then, when a setting is made to install an earthquake-resistant support member, earthquake-resistant support member 2P16 is installed at a position away from earthquake-resistant support member 2P15 at a distance determined by the rules (in the illustrated example, this is assumed to be "6.0 m"; for example, this is obtained from an earthquake-resistant support material master, etc.).

Therefore, the interval display V7 shows "6.0 m." In this way, earthquake-resistant support members, etc. are installed starting from the installed support members, etc.

<Example of interval change midway>
There are cases where the spacing is changed while the support members are being installed. For example, in the following cases:

Figure 36 shows an example where the spacing is changed midway. An example where the spacing is changed midway is at the joint between pipes PI11 and PI12.

Pipes PI11 and PI12 have different pipe sizes. In the illustrated example, pipe PI11 is larger than pipe PI12. When the sizes differ in this way, the spacing may differ based on rules. Specifically, in this example, spacing DIS1 is applied to the spacing between pipes PI11. As shown by spacing display V8, spacing DIS1 is set to "9.0 m."

On the other hand, the distance DIS2 is applied to the distance between the pipes PI12. The distance DIS2 is set to "6.0 m" as shown by the distance display V9. In other words, this is an example in which the distance DIS2 is stricter than the distance DIS1.

As shown in the figure, there is a joint where the pipes PI11 and PI12 switch. For the interval in this part, i.e., the interval DIS3, the stricter of the intervals DIS1 and DIS2 is adopted. Specifically, the interval DIS3 is set to "6.0 m", the same as the interval DIS2. Therefore, the interval display V10 showing the interval DIS3 is displayed as "6.0 m".

As such, depending on the rules used, there may be areas where the spacing overlaps. In such cases, the strictest of the multiple values is adopted. In areas where multiple values can be applied, applying the strictest value often does not pose a problem in terms of safety and rules. Therefore, in cases where multiple objects are mixed, adopting the narrower spacing and installing support members can reduce risks in terms of safety and rules.

For example, you can confirm the installation by performing the following operations:

Figure 37 is a diagram (part 5) showing an installation example. In the case of Figure 36, first, the starting point is assumed to be starting point PT6. Next, in order to determine the range and route for placement, an operation is performed to input the point at which the placement starting from the starting point PT ends (hereinafter referred to as the "end point"; in the illustrated example, this is end point PT7).

For example, the end point PT7 is specified by first clicking the position of the start point PT6, and then clicking the position of the end point PT7.

When this operation is performed, it is possible to determine that the area between the starting point PT6 and the end point PT7, i.e., the target range EA1, is the range in which earthquake-resistant support members are to be installed. If there are any support members already installed in the target range EA1, they will be deleted and new earthquake-resistant support members will be installed.

<Example of installation on multiple routes>
For example, in the case where the target area is the same as the target area EA1 shown in FIG. 37, the starting point PT6 is moved as follows to perform installation.

Figure 38 shows an installation example (part 6). Below, we will explain an example in which the starting point set at the starting point PT6 is moved to the new starting point PT8, as shown in the figure.

For example, suppose there is an obstacle in range EA2. In other words, range EA2 is an area where earthquake-resistant support members cannot be installed. Since earthquake-resistant support members cannot be installed in an area such as range EA2, the starting point may be moved to a new starting point PT8, i.e., a position immediately before range EA2, making range EA2 an area where the installation of earthquake-resistant support members is not required.

In this way, by setting a new starting point near an obstacle, etc., the area where earthquake-resistant support members cannot be installed can be made into an area where earthquake-resistant support members do not need to be installed.

In such a case, earthquake-resistant support members are installed starting from the new starting point PT8 and extending in both directions along route A1 and route A2. Specifically, this is determined as follows:

Figure 39 is a diagram (part 7) showing an installation example. Compared to Figure 37, even if the target object and target range are the same, the starting point is different, so the earthquake-resistant support members are installed in different positions. In this way, being able to install along multiple routes makes it easy to install earthquake-resistant support members while avoiding obstacles, etc.

<Example of display taking into consideration supporting members outside the installation range>
40 is a diagram (part 8) showing an installation example. For example, in the installation range RG as shown in the figure, it is assumed that earthquake-resistant support member 2P20, earthquake-resistant support member 2P21, and earthquake-resistant support member 2P22 are installed. Meanwhile, it is assumed that already-installed support member 2P17, already-installed support member 2P18, and already-installed support member 2P19 have already been installed. It is also assumed that already-installed support member 2P17, already-installed support member 2P18, and already-installed support member 2P19 are installed outside the installation range RG.

As shown in the figure, earthquake-resistant support member 2P20, earthquake-resistant support member 2P21, and earthquake-resistant support member 2P22 are assumed to be earthquake-resistant support members installed on the leftmost side of installation range RG. Therefore, it is assumed that there are no earthquake-resistant support members within installation range RG to the left of earthquake-resistant support member 2P20, earthquake-resistant support member 2P21, and earthquake-resistant support member 2P22.

In such a case, the distance between the newly installed earthquake-resistant support member and the already installed support member is calculated, and the calculation result is displayed in the distance display. Specifically, the distance between the already installed support member 2P17 and earthquake-resistant support member 2P20 is displayed in the distance display V11. The distance between the already installed support member 2P18 and earthquake-resistant support member 2P21 is displayed in the distance display V12. Furthermore, the distance between the already installed support member 2P19 and earthquake-resistant support member 2P22 is displayed in the distance display V13.

In this example, intervals that are wider than the intervals defined by the rules are highlighted. Specifically, this is an example in which the interval display V11 is highlighted.

The spacing between the piping on which the installed support member 2P17 and the earthquake-resistant support member 2P20 are installed is set by the rules to "9.0 m." On the other hand, the spacing between the installed support member 2P17 and the earthquake-resistant support member 2P20 is "12.0 m," as shown by the spacing display V11. Therefore, the spacing between the installed support member 2P17 and the earthquake-resistant support member 2P20 is wider than the spacing set by the rules, and is therefore highlighted by the spacing display V11. Note that the spacing display V11 is an example of a display that highlights the numerical value indicating the displayed spacing by decorating it with a rectangle.

On the other hand, the spacing between the installed support member 2P18 and the seismic support member 2P21 in the piping is regulated by the rules as "6.0 m." Meanwhile, the spacing between the installed support member 2P18 and the seismic support member 2P21 is "4.6 m," as shown by the spacing display V12. Therefore, the spacing between the installed support member 2P18 and the seismic support member 2P21 is narrower than the spacing regulated by the rules, and so the rules are met. Therefore, the spacing display V12 is not highlighted, indicating that the rules are met.

In many cases, the rules must be met even if the position crosses the boundary of the installation range RG. On the other hand, since an installed support member has already been installed, there are cases in which the spacing cannot be narrowed by changing the position of the installed support member. Therefore, as shown in the figure, it is necessary to check whether the spacing between the newly installed earthquake-resistant support member and the installed support member satisfies the rules. Furthermore, by highlighting spacing that does not satisfy the rules as shown in the figure, the user can reduce the work of manually checking the spacing for earthquake-resistant support members installed near the boundary of the installation range RG, thereby reducing the workload.

<Example of earthquake-resistant support member settings>
The earthquake-resistant support members are set, for example, in the dialogue SET shown in Fig. 27. Specifically, for example, the following setting values are set in the dialogue SET.

The "top floor" is set to the top floor of the building on which the earthquake-resistant support members are installed. For example, the "top floor" is obtained from design data or floor information, etc. If it cannot be obtained from the data, the field is left blank and the user inputs a number.

The "target floor" is set to the floor of the building where the earthquake-resistant support member is to be installed. For example, the "target floor" is obtained from design data or floor information, etc. If it cannot be obtained from the data, the field is left blank and the user inputs a numerical value.

The "floor type" is set to one of "upper floor," "middle floor," or "basement/first floor." In a two- to six-story building, the "upper floor" corresponds to the top floor. In a seven- to nine-story building, the "upper floor" corresponds to the second floor from the top. In a ten- to twelve-story building, the "upper floor" corresponds to the third floor from the top. In a building with 13 or more floors, the "upper floor" corresponds to the fourth floor from the top. Meanwhile, a "middle floor" corresponds to a floor that does not correspond to an "upper floor" or a "basement/first floor."

The "earthquake resistance class" can be set to either "S," "A," or "B."

The "support method" specifies the method for supporting the object using earthquake-resistant support members.

When "Settings" is pressed, a screen will appear where you can view and set the input contents of various pre-entered masters.

<Examples of earthquake-resistant support components>
The earthquake-resistant support member is, for example, a support member having the following specifications.

First, an earthquake-resistant support member covers a length that is "1/2" the distance between the adjacent earthquake-resistant support members installed on either side of the position where it is installed, as follows:

Figure 41 is a diagram showing an example of the length covered by an earthquake-resistant support member. Hereinafter, the earthquake-resistant support member in question will be referred to as "earthquake-resistant support member 2P24." Therefore, the adjacent earthquake-resistant support members are "earthquake-resistant support member 2P23" (the one on the left in the figure) and "earthquake-resistant support member 2P25" (the one on the right in the figure). In addition, the length covered by earthquake-resistant support member 2P24 will be referred to as "coverage length DIS4."

The "1/2" of the distance DIS5 between earthquake-resistant support members 2P24 and 2P23 corresponds to half of the support length DIS4 (the left half in the figure).

The "1/2" of the distance DIS6 between earthquake-resistant support members 2P24 and 2P25 corresponds to half of the support length DIS4 (the right half in the figure).

Therefore, "1/2" of the interval DIS5 and "1/2" of the interval DIS6 are the corresponding length DIS4. The earthquake-resistant support member is a support member that reinforces the object installed at the corresponding length DIS4 so that it can withstand earthquakes, i.e., can withstand shaking caused by earthquakes, etc.

The specifications for earthquake-resistant support members are determined, for example, as follows:

Load capacity: 2.8 kN (kilonewtons)
Duct outer diameter: 500 mm (millimeters)
Slab height: 4000 mm
Duct bottom height: 2900 mm
Pipe weight: 5 kN
Bracket width (corresponding to "support dimension l" in the following diagram): 1000 mm
Bracket height (corresponding to "support dimension h" in the following diagram): 1500 mm
The "weight" is a value that can be calculated as follows: By searching the component weight master using the pipe type and diameter as keys, the weight in 1-meter units can be obtained. The "weight" is then calculated by multiplying the 1-meter unit by the length of the pipe.

The "support bracket width" is a value that is calculated as follows. First, the width is calculated based on the outer diameter and steel size of the pipe or duct to be installed. Next, the appropriate steel width is obtained from the seismic support component master using the "support weight" as a key, and the value is determined.

"Support bracket height" is a value calculated based on the height of the duct or pipe, the height of the slab, and the size of the steel.

"Steel size" is a value obtained from the seismic support component master using "support weight," "bracket width," and "bracket height" as keys.

"Anchor size" is a value obtained from the seismic support component master using the "bearing weight," "bracket width," and "bracket height" as keys.

The above values can be illustrated as follows:

Figure 42 shows an example of an earthquake-resistant support member. Figure 42 (A) shows a case where a square duct is supported as the object. On the other hand, Figure 42 (B) shows a case where a pipe is supported as the object.

The width of the upper part of the receiving bracket DIS7 is determined by the number of anchors.

<Example of earthquake-resistant support component master>
The seismic support member master is, for example, a table shown in "Appendix 2.1-6 Example of A-class seismic instruction member selection table for horizontal piping (No. 6)" in "Guidelines for seismic design and construction of building equipment, 2014 edition, published by the Building Center of Japan, edited by the editorial committee for the Guidelines for seismic design and construction of building equipment, 2014 edition, first edition published on September 25, 2014" (hereinafter simply referred to as "Guidelines for seismic design and construction of building equipment"). For example, in the case of such a seismic support member master, in the above example of "pipe weight: 5 kN", "bracket width: 1000 mm", and "bracket height: 1500 mm", the "steel size" is determined as "channel steel 75 x 40 x 5 x 7". In addition, the "anchor size" is determined as "M10".

<Examples of the first and second rules>
The first rule and the second rule are, for example, a table shown in "Guideline Table 6.2-1 Application of Seismic Support" in the "Guidelines for Earthquake-Resistant Design and Construction of Building Facilities."
For example, when using such rules, the interval is determined by the "installation location," the type of object (in the "Guidelines for Earthquake-Resistant Design and Construction of Building Equipment," this is either "piping,""duct,""electricalwiring," or "cable rack"), and the seismic class, etc.

The "installation location," type of object, and seismic resistance class are set, for example, in the dialogue SET.

In addition, depending on the seismic class, the specifications for seismic support members will differ, as shown in, for example, "Appendix 2.1-6 Example of A-class seismic instruction component selection table for horizontal piping (No. 6)" in the "Guidelines for seismic design and construction of building equipment" and "Appendix 2.2-6 Example of S-class _A- class seismic instruction component selection table for horizontal piping (No. 6)" in the "Guidelines for seismic design and construction of building equipment."

Specifically, by using "Appendix 2.1-6 Example of A-class seismic instruction component selection table for horizontal piping (No. 6)" in the "Guidelines for Earthquake-Resistant Design and Construction of Building Equipment" and "Appendix 2.2-6 Example of S-class _A- class seismic instruction component selection table for horizontal piping (No. 6)" in the "Guidelines for Earthquake-Resistant Design and Construction of Building Equipment", once "pipe weight P (kN)", "support material dimension l (mm)", "support material dimension h (mm)", etc. are determined for each earthquake resistance class, "component specification A material", "slab fixing" of "structure mounting anchor", and "beam fixing" of "structure mounting anchor", etc. can be determined.

As mentioned above, the specifications of earthquake-resistant support members are determined by the earthquake resistance class, etc.

<Example of insert master>
The insert master is, for example, a table shown in "Solution Table 6.2-1 (a) Example of standard support intervals for horizontal steel pipes and copper pipes" in "SHASE-S010-2013 Standard Specifications for Heating, Air-Conditioning and Sanitary Equipment Construction, Society of Heating, Air-Conditioning and Sanitary Engineers of Japan (public corporation)" and "Solution Table 6.2-1 (b) Example of standard support intervals for horizontal pipes" in "Ministry of Land, Infrastructure, Transport and Tourism, Minister's Secretariat, Government Maintenance Department, Standard Specifications for Public Building Construction (Mechanical Equipment Construction Edition), 2013 Edition."

With this kind of data, for example, once the "nominal diameter (A)" and whether it is a "steel pipe" or a "copper pipe" are determined based on "Table 6.2-1 (a) Example of standard support intervals for horizontal steel and copper pipes" in "SHASE-S010-2013 Standard Specifications for Heating, Air-Conditioning and Sanitary Equipment Construction" published by the Society of Heating, Air-Conditioning and Sanitary Engineers of Japan (public corporation), the "support interval" etc. can be determined.

Similarly, for example, once the "nominal diameter" and "classification" are determined based on "Example of standard support intervals for horizontal pipes" in the "Standard Specifications for Public Building Construction (Mechanical Equipment Construction Edition) 2013 Edition" of the Ministry of Land, Infrastructure, Transport and Tourism, Minister's Secretariat, Government Maintenance Department, the standard support interval is determined.

<Modification>
The design device may have the following configuration, for example.

<Modifications of input/output screens, etc.>
The method of calculating the first passable range is not limited to the above method, but may be determined based on predetermined rules or the like.

The setting values that can be entered on the input/output screen may differ depending on the options in the calculation method input section IN11. For example, in the case of "Calculate valid range only," the GUI may be such that the setting values for each item in "Pipe type selection," such as the outer diameter, insulation thickness, air gap, and required opening diameter, cannot be entered. In this way, when unnecessary setting values are automatically made unavailable for input, the user can reduce the work of inputting unnecessary setting values and lighten the workload.

The type of penetrating object may be other than those shown in the figure. That is, the penetrating object may be an object other than the "pipe" or "duct" shown in the above example. For example, the penetrating object may be a cable, etc.

Setting values for "top floor" and "target floor" may be obtained from design data, etc. In this way, when data is automatically obtained from design data, etc. and setting values are input for calculation, the user does less work to input setting values, reducing the workload.

In addition, data such as the time that a penetrating object can withstand a fire, etc. (hereinafter referred to as the "fire resistance reference time") may be obtained from design data, etc. For example, the fire resistance reference time is obtained from among "1 hour," "2 hours," "3 hours," etc.

The fire resistance standard time may be determined by rules, etc. Specifically, it is determined in "Article 8 of the Fire Service Act Enforcement Order" etc. More specifically, for "compartments of fire-resistant floors or walls without openings as stipulated in Article 8 of the Fire Service Act Enforcement Order," "Notice No. 53 (March 31, 1995) on the structure of Ordinance 8 compartments and shared compartments and the handling of piping, etc. penetrating said compartments" stipulates that "O. The piping and the penetration parts, as a whole, must have the performance to withstand heating during a normal fire for more than two hours as stipulated in Article 107, item 1 of the Building Standards Act Enforcement Order." In such a case, the fire resistance standard time is obtained as "2 hours." In this way, if the setting value stipulated in the rules, etc. can be automatically input or selected, the user does less work to input the setting value compared to looking up the rules, etc., and the workload can be reduced.

In addition, if the "Beam type" is other than "S", "Covering" and "Fireproof coating thickness (t2) (Beam body)" may be grayed out or otherwise prevented from being input or output. In this way, if unnecessary setting values are automatically prevented from being input, the user can reduce the work of inputting unnecessary setting values and lighten the workload.

The numerical values such as "[H] Required opening diameter" may be numerical values with further leeway.

It should be noted that values may be input into the penetrating object dimension display unit IN15, etc. In other words, the penetrating object dimension display unit IN15 may be a GUI or the like that allows the user to input any value. In such a case, related values may be recalculated based on the value input by the user. With such a configuration, it becomes easy for the user to input various setting values and conduct examinations. In other words, with such a configuration, the workload of the user recalculating various setting values can be reduced.

The first passable range display unit IN16, etc. may be displayed as a fraction, such as "1/3." That is, depending on the rules or the user, fractions may be easier to handle. Therefore, a GUI that displays fractions may be easier for the user to operate.

If the "required opening diameter [H]" exceeds "1/3" of the "beam depth [D]", an error message may be displayed. When such an error message is displayed, the user can know that there is a beam that cannot be opened to the "required opening diameter [H]".

Note that values such as "[L1] edge clearance dimension" may be common to different beam types. In this way, if common values can be used, the effort of repeatedly inputting the same setting value can be reduced. This reduces the workload of the user in inputting setting values, etc.

The input/output screen, i.e., the input of beam data, the input of penetrating object data, and the output of the calculation results of the first passable range, are not limited to the screen shown in the figure. In other words, the calculation of the beam data, the penetrating object data, and the first effective range may be performed by other methods.

For example, the size and material of pipes and other penetrating objects are stipulated by regulations such as the Building Standards Act for the purpose of strength and disaster prevention. Specifically, pipes and the like are stipulated in "Article 129-2-5 of the Enforcement Order of the Building Standards Act" and the like. More specifically, the outer diameter of water supply pipes, distribution pipes, and other pipes that penetrate fire compartments of semi-fireproof construction stipulated by the Minister of Construction based on the provisions of "Article 129-2-5, Paragraph 1, Item 7, (b) of the Enforcement Order of the Building Standards Act" is stipulated in "Ministry of Construction Notification No. 1422 of May 31, 2000". Therefore, items required to calculate dimensions that satisfy the above regulations are input into the input/output screen. On the other hand, the regulations do not have to be laws and regulations such as the Building Standards Act. For example, they may be company regulations that are stricter than the Building Standards Act. Therefore, depending on the regulations and calculation method to be applied, the setting values may be of types other than those shown in the figure. With this configuration, it is possible to calculate the passable range by applying regulations that are stricter than the Building Standards Act and the like.

The design device does not need to calculate the second passable range in which the passing diameter can be secured. The above example is an example in which the result of determining whether or not the passing diameter can be secured in each second passable range is displayed. In other words, whether or not the passing diameter can be secured is displayed with a penetrating object mark, and the calculation result of whether or not the passing diameter can be secured is displayed.

On the other hand, if "Calculate only effective range" is selected in the "Calculation method" on the input/output screen, the design device may perform a process that does not calculate the second passable range (in the illustrated example, this is the range indicated as "effective range", etc.), i.e., does not determine whether the passing diameter can be secured.

In design, etc., there are cases where the user wants to know the extent of the second passable range without specifically setting the settings for the penetrating object, i.e., each item of "pipe type selection", the outer diameter, insulation thickness, gap, and required opening diameter, etc. Therefore, the design device displays the second passable range without the required opening diameter, etc. In this case, the "piping level (core)" is displayed as "-". In this way, the user can know the second passable range without inputting the design value related to the penetrating object. In design, etc., there are cases where the user wants to know first whether there is a range in which the penetrating object can pass straight through (indicating a case in which the penetrating object does not need to be placed upward or downward to pass through in order to avoid beams). In such cases, the user can know the range in which the penetrating object can pass straight through by selecting "Calculate only the effective range" and calculating the second passable range.

<Modification of Display of Passable Range>
In the above example, the same beams are displayed together, but the same beams may be displayed separately. In some cases, such a display is easier to see. In addition, it may be possible to switch between displaying the same beams together or separately. With such a configuration, the second passable range, etc. can be displayed in an easy-to-see manner.

The calculation may take into account the gradient. That is, in the above example, a horizontal pipe was used, but the target does not have to be a horizontal pipe. In this way, when the gradient is taken into account, the range can be calculated with high accuracy even when a gradient is present.

On the display screen, the patterns may be sorted and displayed. For example, the "beam penetration pattern," "number of sleeves," "piping level (core)," and "effective range" in the above example are displayed in order of widest second passable range. Similarly, other items may be set as the key for sorting. In this way, when the second passable ranges are displayed in order of widest, the user can easily identify the second passable range that has the most room to pass the penetrating object.

In addition, the upper limit and lower limit may be displayed on the display screen. For example, on the screens of Figures 11 and 12, the design device indicates the upper limit and lower limit with circles. Specifically, the upper limit of the first pattern PTN1 is displayed by the first pattern upper limit mark OUT25. On the other hand, the lower limit of the first pattern PTN1 is displayed by the first pattern lower limit mark OUT26.

Similarly, the upper limit of the second pattern PTN2 is indicated by the second pattern upper limit mark OUT23. Meanwhile, the lower limit of the second pattern PTN2 is indicated by the second pattern lower limit mark OUT24.

In this way, when the upper and lower limit points are highlighted with marks or the like, the user can easily identify the upper and lower limit beams. Depending on the design, it may be possible to change the upper limit beam or the lower limit beam. Or, it may be possible to bypass the upper limit beam or the lower limit beam and create a different route. By making design changes in this way, the second passable range can be widened. Therefore, a configuration that displays in this way can make it easier for the user to make design changes.

It is desirable that the marks indicating the upper and lower limits are displayed, for example, in different colors. With this configuration, the design device can display the upper and lower limits on the screen in an easy-to-understand manner for the user.

In addition, it is desirable to be able to operate to enlarge or reduce the screen on a display screen such as that shown in FIG. 11 or FIG. 12. For example, when an operation to rotate the wheel of a mouse is performed while a display screen such as that shown in FIG. 11 or FIG. 12 is being displayed, the screen is enlarged or reduced according to the direction and amount of rotation of the wheel. Note that the operation to enlarge or reduce the screen is not limited to an operation using the wheel. In other words, the operation to enlarge or reduce the screen may be realized by other methods such as a GUI.

In this way, being able to zoom in or out on the screen allows the user to change the screen size to one that is easy to see.

The method of distinguishing and displaying beams is not limited to color coding. In other words, the method of distinguishing and displaying beams only needs to be such that the user can tell whether the beam is to be penetrated or avoided when looking at the screen. For example, one side may be filled with a specified color and highlighted by blinking or hatching. The method of distinguishing and displaying beams may also be set by the user. In other words, the user may be able to specify how the beams are to be distinguished and displayed in a way that is easy for the user to see. When the beams are distinguished and displayed in this way, the design device can distinguish and display them in a way that is easy for the user to distinguish.

The results of comparing the latest calculation result with the previous calculation result may be displayed with differences emphasized, for example. For example, if the beam data is different, the settings for the beams may be emphasized. In this way, when the differences are emphasized, the user can reduce the effort of searching for the differences.

The design device may also be able to check for interference with beams or penetrating objects. By being able to check for interference in this way, the user can check whether the design involves interference with beams or penetrating objects.

<Modification of the second embodiment>
The interval may be set to a value narrower than the interval specified by the rules, i.e., a stricter interval than the interval specified by the rules. In other words, stricter in-house rules may be used than the rules specified by laws, etc. In this way, if an interval stricter than the interval specified by the rules can be set, it may be possible to achieve a higher earthquake resistance than the earthquake resistance assumed by laws, etc.

The first and second support members may be installed at the same time, or one of them may be installed beforehand. By using one of the members that has already been installed, it is possible to calculate an installation position that makes effective use of the support material that has already been installed. Furthermore, by using a support material that has already been installed, it is possible to calculate an arrangement that minimizes changes to the arrangement of the support material that has already been installed. This makes it possible to reduce the amount of construction work that changes the arrangement of support materials that have already been installed.

The installation range is not limited to a rectangular range specified by diagonal points. For example, the installation range may be specified as a polygon. If the installation range can be specified as a polygon, it is possible to finely separate the range that is the installation range from the range that is not.

When installing support members, if installing them while avoiding areas where installation is not possible, it is desirable to install them so that the spacing between the support members is narrow. If the spacing between the support members is wider, the spacing may not satisfy the specified rules. On the other hand, if the spacing between the support members is narrower, the spacing will often satisfy the specified rules. Therefore, when avoiding areas where installation is not possible, narrowing the spacing between the support members will result in an installation that satisfies the specified rules.

Also, for example, as shown in FIG. 28, in a portion close to the boundary of the installation range, the interval display may indicate the distance to the boundary of the installation range (in the illustrated example, this is the portion indicated by boundary line L1). Specifically, in the illustrated example, earthquake-resistant support member 2P4, earthquake-resistant support member 2P5, and earthquake-resistant support member 2P6 are the targets. Also, it is assumed that there are no other support members ahead of earthquake-resistant support member 2P4, earthquake-resistant support member 2P5, and earthquake-resistant support member 2P6 (including outside the installation range RG).

In this case, the spacing display V1 indicates the distance from the earthquake-resistant support member 2P4 to the boundary line L1. Similarly, the spacing display V2 indicates the distance from the earthquake-resistant support member 2P5 to the boundary line L1. Furthermore, the spacing display V3 indicates the distance from the earthquake-resistant support member 2P6 to the boundary line L1. Such spacing displays can be used as a reference when considering whether or not it is better to install additional support members in order to satisfy the specified rules.

The interval display may also display a numerical value that includes the distance of the so-called rise or fall. For example, in the example of FIG. 29, if there is an obstacle, i.e., a section where it is difficult to install the piping PI in a straight line, the piping PI may be installed to avoid the obstacle.

Specifically, in the figure, the pipe PI may avoid obstacles not on the XY plane (left-right and up-down directions in the figure), but in the rising or falling direction (i.e., the Z-axis direction; in the figure, the depth direction). Such cases can be understood, for example, from design data, etc. Therefore, it is desirable for the interval display V4 to display an interval that includes the distance of the rising or falling. With such an interval display, even if there is a rising or falling edge, it is possible to reduce the work of manually recalculating the interval to take the rising or falling edge into account.

The candidate point is not limited to being at the same position in the X-axis direction as the earthquake-resistant support member installed on the other pipe. In other words, the design device may assist in matching the cursor to a position other than the intersection of the pipe and the auxiliary line drawn from the earthquake-resistant support member installed on the other pipe.

For example, the candidate points may be characteristic points such as the end points of a pipe, the center of a pipe (or a part of a pipe), a point where a pipe bends, an extension point of a pipe, or an intersection point of multiple extensions of pipes (a so-called "virtual intersection point"). If such points are also included as candidate points, the operation becomes easier.

The starting point (including a new starting point) may be able to be set outside the installation range. If there are obstacles, it is desirable to install the earthquake-resistant support members by avoiding the obstacles. For example, it may be good to set the starting point outside the installation range in order to avoid obstacles. Therefore, if the starting point can be set outside the installation range, it is possible to flexibly set up the earthquake-resistant support members by avoiding obstacles.
