Description

The present invention relates to a design support device that supports the design of buildings, a design support method using such a design support device, and a design support program for realizing such a design support device.

CAD (Computer Aided Design) systems that use computers to assist in the design of buildings are becoming widespread. For example, Patent Document 1 discloses a method for designing a unit building in which a rough design is carried out to set the positions of structurally influential parts of the building (such as staircases, openings formed in horizontal planes such as atriums, etc.) that affect the structure of the building and the arrangement of building units according to the floor plan set by the customer's requests and plans, and then structural calculations are carried out from this arrangement data, and specific design designs for partitions, etc. are carried out only if a certain structural strength is satisfied.

For openings such as escape hatches that are installed on the horizontal surface of a building's balcony, etc., there are situations where prohibitions must be determined, such as the need to place a long horizontal member such as a beam of an appropriate type in an appropriate position on the same floor as the horizontal surface, depending on the type of horizontal surface.

Japanese Patent Application Publication No. 08-123837

However, the design method for a modular building disclosed in Patent Document 1 does not take into consideration determining prohibitions on long horizontal members placed near an opening in relation to the opening on the horizontal surface of the building.

The present invention was made in consideration of these circumstances, and its main objective is to provide a design support device that can determine whether a long horizontal member is appropriately positioned on the same floor as an opening on a horizontal surface of a building, based on its relationship with the opening.

The design support device is also characterized in that the horizontal surface of the building is the floor of a balcony, the opening is an escape hatch, and the long horizontal member is a beam.

In addition, in the design support device, the horizontal member arrangement direction identification means identifies the side of the escape hatch by acquiring the opening/closing direction of the escape hatch, and the pair of opposing sides acquired as lines by the line segment acquisition means is the side portion of the outer edge of the escape hatch.

The device is also characterized in that it includes a type acquisition means for acquiring the type of the balcony and the type of the beam detected at the position overlapping with the moved line segment, and when the acquired balcony type is a full flat balcony, the determination means determines whether the type of beam satisfies a condition that must be satisfied by both of the set of moved line segments and the beam detected at the position overlapping with the set of moved line segments, and whether the type of beam satisfies a condition that must be satisfied by at least one of the set of moved line segments, and performs prohibition processing.

Furthermore, the design support method disclosed in the present application is a design support method using a design support device that supports the design of placing a long horizontal member on the same floor as an opening opened on a horizontal plane of a building, and is characterized by executing the steps of: determining the direction in which to place the long horizontal member as seen from the opening; acquiring a line segment having the length of the opening in the longitudinal direction of the horizontal member in a plan view on the area occupied by the opening; determining a reference point within the area occupied by the opening in a plan view; moving the acquired line segment from the determined reference point to a position a predetermined distance away in the direction in which the horizontal member is to be placed; and determining whether the horizontal member is appropriately placed based on the placement status of the horizontal member at the position where it overlaps with the moved line segment.

Furthermore, the design support program disclosed in the present application is a design support program that causes a computer to assist in the design of placing a long horizontal member on the same floor as an opening opened on a horizontal plane of a building, and is characterized in that the computer executes the steps of: determining the direction in which to place the long horizontal member as seen from the opening; acquiring a line segment having the length of the opening in the longitudinal direction of the horizontal member in a plan view on the area occupied by the opening; determining a reference point within the area occupied by the opening in a plan view; moving the acquired line segment from the determined reference point to a position a predetermined distance away in the direction in which the horizontal member is to be placed; and determining whether the horizontal member is appropriately placed based on the placement status of the horizontal member at the position where it overlaps with the moved line segment.

The present invention determines whether a long horizontal member is appropriately positioned on the same floor as an opening on a horizontal surface of a building by moving a line segment obtained from the area that the opening occupies in a plan view a specified distance. This has the excellent effect of making it possible to determine prohibitions related to the placement of long horizontal members and to support the design of buildings.

The following describes in detail an embodiment of the present invention. Note that the following embodiment is an example of the present invention and is not intended to limit the technical scope of the present invention.

<Application Examples>
The design support system disclosed in the present application is applied to a system such as a CAD (Computer Aided Design) system that supports the design of a building. The design support system disclosed in the present application is a system that can be applied to determine whether or not the design contents, such as the arrangement of members that constitute a building, fall under a predetermined prohibition, and in particular, determines the prohibition regarding a long horizontal member to be placed on the same floor as an opening opened on a horizontal plane of the building. A specific example of an opening opened on a horizontal plane of the building can be an escape hatch opened on the floor of a balcony, and a specific example of a long horizontal member can be a beam. A specific example of a prohibition can be an inappropriate situation such as a beam that should be placed near an escape hatch opened on the floor of a balcony on the same floor as the escape hatch is not placed in an appropriate position. In the following, a design support system using a design support device 1 described in the drawings will be described with reference to the drawings.

<System Configuration>
1 is an explanatory diagram showing an example of the configuration of a design support system disclosed in the present application. The design support system disclosed in the present application is a system including a design support device 1 capable of executing a system such as a CAD system for creating and displaying drawings such as floor plans for buildings such as houses. The design support device 1 is configured using a computer such as a desktop computer, a notebook computer, or a tablet computer equipped with a CAD design system. The design support device 1 is connected to a communication network NW such as the Internet, a wide area network (WAN), a local area network (LAN), or a dedicated communication network. The design support device 1 is used by a building designer as a CAD system for creating drawings.

The communication network NW is connected to a core device 2 that constitutes the core system of the CAD system. The core device 2 is configured using a computer such as a general-purpose computer used as a server computer. The core device 2 is connected to store or communicate with various databases such as a CAD information database DB1, a component information database DB2, and a check result database DB3.

The CAD information database DB1 is a database that stores CAD data showing the structure of each building. The component information database DB2 is a database that stores information about components used in buildings. The check result database DB3 is a database that stores the results of checks on the structure of buildings.

Various devices such as the design support device 1 can access the core device 2 via the communication network NW to read and write information stored in various databases.

<Hardware configuration of the device>
Next, an example of the configuration of each device used in the design support system will be described. Fig. 2 is a block diagram conceptually showing an example of the configuration of each device used in the design support system disclosed in the present application. The design support device 1 includes various components such as a control unit 10, a storage unit 11, an input unit 12, a display unit 13, and a communication unit 14.

The control unit 10 is a processor such as a CPU (Central Processing Unit) that includes various circuits such as an information processing circuit, a timer circuit, and a register circuit, and executes processes to control the entire device.

The storage unit 11 is a storage unit configured using non-volatile memories such as a hard disk, an SSD (Solid State Drive), a RAID (Redundant Arrays of Inexpensive Disks), and a flash memory, and volatile memories such as various RAMs (Random Access Memories). The storage unit 11 stores programs such as a basic program (OS: Operating System) and an application program that runs on the basic program. As application programs, various programs such as a CAD program 110 for implementing a CAD system and a design support program 111 for implementing the design support device 1 disclosed in the present application are stored. The design support program 111 is, for example, a checking program that is executed as a tool on the CAD program 110.

In addition, a part of the memory area of the memory unit 11 is used as various databases such as a CAD information database 112, a component information database 113, and a check result database 114. The contents stored in the various databases such as the CAD information database 112, the component information database 113, and the check result database 114 are local databases that are substantially similar to databases of the same name connected to the communication network NW or that are extracted from portions of such databases.

The CAD information database 112 is a database that stores various information, such as CAD data related to two-dimensional or three-dimensional design drawings of buildings, in association with a building ID that identifies the building. The CAD data includes component data expressed in a format such as a vector format that indicates geometric objects such as points, lines, and areas.

3 is an explanatory diagram conceptually illustrating an example of the contents stored in the component information database 113 used in the design support system disclosed in the present application. The component information database 113 is a database that stores information on various components used in a building indicated by CAD data, in association with a building ID. As information on components, various information such as type information indicating the type of component and placement information indicating the placement position of the component are stored in association with a component ID that identifies the component. The type information is information indicating the type of floor, beam, escape hatch, etc. The type information is appropriately set with specification information indicating the specification. For example, for a component whose type is a roof balcony, specification information indicating the specification of a full flat balcony, etc. is set. In addition, for example, for a component whose type is a beam, specification information indicating the type of beam, cross-sectional shape, cross-sectional size (cross-sectional height, width, web thickness, flange thickness), etc. is set. Specifically, beams are classified by symbols based on differences in the type of beam, cross-sectional shape, cross-sectional size, etc., and symbols such as "G1", "G2", and "B1" are set as specification information for the beam. In this code, the type of beam is classified by alphabet, such as "G" for a main beam, "B" for a minor beam, and "E" for a wind-resistant beam, and the thickness of the cross-section of the member in each type is classified by number, such as "1" or "2". In addition to these specifications, various information such as the manufacturer, grade, weight, and custom-made product can be stored as specification information. The specific type of member is specified by the type information and specification information. The placement information is information indicating the placement position and placement direction of the member, and information indicating the floor and coordinates indicating the placement position and the placement direction is stored. Note that the floor in this application includes the floor surface on which the opening is opened, the structures such as beams attached to the floor, and the ceiling surface of the floor below, and "the same floor as the opening" does not only refer to the horizontal surface on which the opening is opened, which has no geometric thickness.

FIG. 4 is an explanatory diagram conceptually illustrating an example of the contents stored in the check result database 114 used in the design support system disclosed in the present application. The check result database 114 is a database that stores data on check results for each item, such as a rule check code, error level, title, comment, hierarchy, and placement position, in association with a result ID. The rule check code is information that identifies a program, such as a check program for executing a rule applied to the check. The error level is information that indicates the degree of error that is output when the check result is an error. The title is information that indicates the content of the check. The comment is information that indicates a comment output as a check result. The hierarchy is information that indicates the hierarchy in which an object such as a component in which an error has occurred is placed. The placement position is information that indicates the placement position of an object such as a component in which an error has occurred, and is indicated by information such as the coordinate attribute, the number of coordinate points, and the coordinate value. The coordinate attribute is information that indicates a geometric shape defined by the coordinates of a point, a line segment, a broken line, a polygon, etc. The number of coordinate points is information that indicates the number of coordinates used to identify a geometric shape.

Returning to the block diagram of FIG. 2, the input unit 12 is a device such as a keyboard, a mouse, a touch panel, or a digitizer. The display unit 13 is a device such as a liquid crystal display. Note that the input unit 12 and the display unit 13 may be provided as a liquid crystal touch panel in which a thin-plate-shaped liquid crystal display and a touch panel are stacked, for example.

The communication unit 14 is a device such as a LAN adapter, an antenna, and a control circuit, and is connected to the communication network NW via wired or wireless communication, and communicates with various devices including various databases.

A computer having the various configurations exemplified above operates as a design support device 1 by reading various programs such as a CAD program 110 and a design support program 111 stored in the memory unit 11 under the control of the control unit 10 and executing various procedures contained in the read programs.

Regarding access to various databases, the control unit 10 and the communication unit 14 may be used as access means to access various databases provided in the core device 2 connected via the communication network NW, or the control unit 10 may be used as access means to access various local databases stored in the storage unit 11. In the following, examples of forms for accessing various local databases stored in the storage unit 11 will be described.

<Software Processing of the Apparatus>
Next, the processing of the design support device 1 used in the design support system will be described. Fig. 5 is a flow chart showing an example of a horizontal member placement check process of the design support device 1 used in the design support system disclosed in the present application. The horizontal member placement check process is a process for checking the suitability of the placement position and the suitability of the type of a long horizontal member that should be placed at a position a predetermined distance away from an opening on a horizontal surface of a building on the same floor.

The control unit 10 of the design support device 1 executes various programs such as the CAD program 110 and the design support program 111 to perform the horizontal member placement check process. The control unit 10 of the design support device 1 executes the CAD process (step S1). The CAD process in step S1 indicates the design support process by the CAD system. The CAD process is performed by accessing the CAD information database 112, extracting CAD data such as CAD data stored in association with the building ID and CAD data that is a basic plan stored in advance, and adding and changing the contents as appropriate. During the CAD process, the design support device 1 executes the subsequent horizontal member placement check process by manual processing by the designer's operation or automatic processing triggered by the occurrence of an event such as the end of design.

The control unit 10 accesses the component information database 113 to refer to the stored contents such as type information, and from the component data included in the CAD data being processed, identifies as target openings those openings indicated by the component data whose type information is an escape hatch that are arranged on the same level as components whose type information indicates an area whose type information is a roof balcony (step S2). Step S2 is a process of decomposing the CAD data into geometric objects such as points, lines, areas, etc., and classifying the data into component units by referring to the component information database 113, and identifying components whose type information is stored as an escape hatch (areas occupied by the target openings) as targets for checking the appropriateness of placement. In addition, compartments such as balconies and rooms, and further compartments separated by horizontal members such as beams and lintels, are classified as components that indicate areas.

The control unit 10 accesses the component information database 113 and identifies the direction in which to place the long horizontal member as seen from the target opening by referring to the stored contents of the placement information of the target opening and the placement direction of the target opening (step S3). Next, the control unit 10 obtains a line segment that has the maximum length of the target opening in the longitudinal direction of the horizontal member in a plan view on the area occupied by the target opening (step S4).

Figure 6 is an explanatory diagram conceptually showing an example of the horizontal member placement check process of the design support device used in the design support system disclosed in the present application. Figure 6 conceptually shows the processes of steps S2 to S4. As illustrated in Figure 6, the design support device 1 identifies the target opening in step S2 and refers to the placement direction of the target opening in step S3. The up-down direction in Figure 6 is the placement direction of the escape hatch, which is the target opening H, and this corresponds to the opening and closing direction of the escape hatch. The opening and closing direction of the escape hatch means the front-to-rear direction when facing the escape hatch so that the flap of the escape hatch opens from the front to the back on the horizontal plane on which the escape hatch is provided. When providing an escape hatch on a roof balcony, it is necessary to place a beam in the side direction of the escape hatch, so the direction in which the horizontal member is placed as viewed from the target opening H is a direction perpendicular to the placement direction of the target opening H (the left-to-right direction in Figure 6). In other words, in step S3, the direction in which the long horizontal member is placed as viewed from the target opening H is specified by referring to the placement direction of the target opening H.

6, in step S4, the design support device 1 obtains two line segments L remaining from the four line segments (four sides) forming the substantially rectangular outer edge of the area occupied by the target opening H, excluding two line segments perpendicular to the arrangement direction of the target opening H. In other words, in the example of FIG. 6, the line segment L obtained in step S4 corresponds to a pair of opposite sides of the rectangular outer edge of the target opening H that are located in the direction in which the horizontal member is arranged. As illustrated in FIG. 6, the target opening H having a substantially rectangular shape is a concept that also includes a substantially square shape. In addition, the substantially rectangular shape indicates a shape that can be regarded as substantially a rectangle, and is a concept that also includes shapes such as a rounded rectangle that are not rectangular in the strict sense. Furthermore, the target opening H can be expanded to a circle, an ellipse, a square other than a rectangle, and a polygon other than a square. For example, if the target opening is circular, the line segment with the maximum length of the target opening in the longitudinal direction of the horizontal member to be placed is the diameter of the circle, so by obtaining the diameter of the circle in step S4, it is possible to expand it into a circular shape.

Returning to the flowchart of FIG. 5, the control unit 10 accesses the component information database 113 and refers to the stored contents of the placement information of the target opening, or uses the stored contents of the placement information of the target opening referred to in step S3, etc., to determine a reference point within the area occupied by the target opening in a planar view (step S5). The reference point determined in step S5 is a point that serves as a reference point for the distance to be moved when the line segment acquired in step S4 is moved in step S6 described below.

FIG. 7 is an explanatory diagram conceptually showing an example of the horizontal member placement check process of the design support device used in the design support system disclosed in the present application. FIG. 7 conceptually shows the process of step S5. As illustrated in FIG. 7, the design support device 1 acquires the coordinates of the midpoint P0 of the diagonal of the target opening H of a substantially rectangular shape in step S5, and determines the midpoint P0 as the reference point. The midpoint P0 is derived as coordinates {(X1+X2)/2, (Y1+Y2)/2} by acquiring the coordinates P1 (X1, Y1) of the upper left vertex and the coordinates P2 (X2, Y2) of the lower right vertex of the diagonal as illustrated in FIG. 7. In order to place the horizontal members at equal distances on each side of the target opening H as shown in FIGS. 10 to 12, it is preferable to set the midpoint P0 of the diagonal of the substantially rectangular shape as the reference point. Step S5 (determination of the reference point) can be expanded even when the target opening has a shape other than a substantially rectangular shape by setting the reference point within the area occupied by the target opening. For example, if the target opening is polygonal, the center of gravity of the polygon is set as the reference point, and if the target opening is circular or elliptical, the center of the circle or ellipse is set as the reference point. This determines the reference point in the center of the area occupied by the target opening, making it possible to check whether the horizontal members are placed at an equal distance from the target opening.

Returning to the flowchart in FIG. 5, the control unit 10 moves the line segment acquired in step S4 to a position a predetermined distance away from the reference point determined in step S5 in the direction in which the horizontal member will be placed (step S6).

Figure 8 is an explanatory diagram conceptually illustrating an example of the horizontal member placement check process of the design support device used in the design support system disclosed in the present application. Figure 8 conceptually illustrates the process of step S6. As illustrated in Figure 8, line segment L, which is a pair of opposite sides of the rectangular outer edge of the target opening H obtained in step S4 that is located in the direction in which the horizontal members are placed, is translated from the reference point P0 determined in step S5 toward the direction in which the horizontal members are placed, identified in step S3. Figure 8 illustrates a state in which line segment L has been moved so that the distance (shortest distance) between line segment L and reference point P0 is 500 mm, which is a preset distance.

Returning to the flowchart of FIG. 5, the control unit 10 determines whether a horizontal member is placed at a position overlapping with the line segment moved in step S6 (step S7). Step S7 is a process for determining whether a long horizontal member to be placed near the target opening is placed in an appropriate position.

9 to 12 are explanatory diagrams conceptually illustrating an example of the horizontal member placement check process of the design support device used in the design support system disclosed in the present application. In FIG. 9 to FIG. 12, the rectangles marked with the symbols G1 and G9 represent beams as long horizontal members, and the symbols G1 and G9 are stored as beam specification information in the component information database 113 as described above. In FIG. 9, a beam is placed at the position overlapping with the line segment L on the right side, but no beam is placed at the position overlapping with the line segment L on the left side. In this way, if no beam is placed at the position overlapping with the line segment L, the result is NO in step S7 of the flowchart in FIG. 5. In FIG. 9, no beam is placed at the position overlapping with the line segment L on the left side, but since beams must be placed at all positions overlapping with the line segment L in the escape hatch (target opening H) provided on the roof balcony, if no beam is placed at even a part of the position overlapping with the line segment L, the result is NO in step S7. If beams are placed at all positions that overlap with line segment L, as shown in FIG. 10, the result in step S7 is YES.

Returning to the flowchart of FIG. 5, if it is determined that no horizontal member is placed at a position overlapping the line segment moved in step S6 (step S7: NO), the control unit 10 executes error processing (step S8). The error processing in step S8 is a process for storing data in the check result database 114 that no horizontal member is placed at a position overlapping the line segment moved in step S6 and that the check result is an error. In this error processing, a comment indicating that the check result is an error may be displayed on the display unit 13, or a comment specifying the type of horizontal member to be placed may be displayed on the display unit 13 after the type information of the horizontal surface in which the target opening is opened and specification information are referenced to identify the type of horizontal member to be placed, similar to the prohibition processing in steps S10 to S12 described below.

In an embodiment in which the target opening is an escape hatch provided on a roof balcony, if it is determined that a horizontal member is placed at a position overlapping with the line segment moved in step S6 (step S7: YES), the control unit 10 refers to the type information, etc. stored in the component information database 113 and determines whether the horizontal surface in which the target opening is opened is a full flat balcony (step S9).

For a full flat balcony, there are multiple conditions for the cross-sectional shape and size of the horizontal member to be placed near the target opening. Therefore, if it is determined in step S9 that it is a full flat balcony, the control unit 10 first executes a check process on the horizontal member detected in step S7 (step S10). In step S10, it is determined whether the conditions that must be met by both the line segment moved in step S6 and the horizontal member detected in the overlapping position are met. If the conditions are not met, the control unit 10 executes prohibition process 1 (step S11). Prohibition process 1 is a process in which the conditions in the check process executed in step S10 are not met and a comment indicating that the check result is an error is displayed on the display unit 13, and data related to the check result is stored in the check result database 114.

If the conditions in the check process executed in step S10 are met, the control unit 10 executes a further check process on the horizontal members detected in step S7 (step S12). In step S12, it is determined whether or not the conditions that must be met by at least one of the horizontal members detected at a position overlapping with the line segment moved in step S6 are met. If the conditions are not met, the control unit 10 executes prohibition process 2 (step S13). Prohibition process 2 is a process in which the conditions in the check process executed in step S12 are not met, a comment indicating that the check result is an error is displayed on the display unit 13, and data related to the check result is stored in the check result database 114.

If it is determined in step S9 that the balcony is not a full flat balcony, the control unit 10 executes a check process on the horizontal member detected in step S7 (step S14). In step S14, it is determined whether the conditions that must be met by both the line segment moved in step S6 and the horizontal member detected at the overlapping position are met. If the conditions are not met, the control unit 10 executes prohibition process 3 (step S15). Prohibition process 2 is a process in which the conditions in the check process executed in step S14 are not met, a comment indicating that the check result is an error is displayed on the display unit 13, and data related to the check result is stored in the check result database 114.

By displaying a comment on the display unit 13 in prohibition processing 1 to 3, the designer can recognize that the type of horizontal member placed is inappropriate.

As described above, the component information database 113 stores symbols classified based on the type of beam as a horizontal member, the shape of the cross section, etc., as beam specification information. The design support device 1 obtains the type of beam to be checked using this symbol and executes prohibition processing 1 to 3. In the examples of Figures 10 to 12, the symbols of the beams (beams that overlap with the line segment L) arranged on the left and right of the target opening H are both G1 in Figure 10, G9 and G1 in Figure 11, and G9 in Figure 12. Prohibition processing 1 (step S10), which is performed when the horizontal surface on which the target opening H is opened is a full flat balcony, checks whether the beams that overlap with the line segment L are both included in the group consisting of "G1, G3, G9", and if the symbol of any of the beams is not included in this group, a comment indicating that the check result is an error is displayed on the display unit 13, and data related to the check result is stored in the check result database 114. In the examples of Figures 10 to 12, both G1 and G9 are included in the above group, so prohibition process 2 in step 11 is then performed. Prohibition process 2 (step S11) is a process that checks whether at least one of the beams arranged on the left and right of the target opening H is G9, and if neither is G9, displays a comment indicating that the check result is an error on the display unit 13, and stores data related to the check result in the check result database 114. In the examples of Figures 10 to 12, prohibition process is performed in the case of Figure 10, where G9 is not arranged.

On the other hand, prohibition process 3 (step S12) is performed when the horizontal surface where the target opening H is opened is not a full flat balcony. It checks whether the beams arranged on the left and right sides of the target opening H are both included in the group consisting of "G1, G3, G7, G8, G10, B1, B3, E1, E2". If the symbol of any beam is not included in this group, a comment indicating that the check result is an error is displayed on the display unit 13, and data related to the check result is stored in the check result database 114. Here, the group consisting of "G1, G3, G7, G8, G10, B1, B3, E1, E2" is a group of beams that are pre-selected in which the cross-sectional height, width, and flange thickness of the beams satisfy predetermined numerical conditions. In the examples of Figures 10 to 12, since G9 is not included in the above group, prohibition process 3 is performed in the cases of Figures 11 and 12.

13 is an explanatory diagram showing an example of an image displayed on the display unit 13 of the design support device 1 used in the design support system disclosed in the present application. FIG. 13 illustrates an example of an image including information such as comments output as prohibition processing in steps S11, S13, and S15 shown in the flowchart of FIG. 5. The image illustrated in FIG. 13 shows a floor plan of a building that is the subject of the horizontal member placement check processing, and in FIG. 13, only the escape hatch as the target opening and the beam as a long horizontal member arranged in the side direction of the escape hatch on the same floor are illustrated, and other elements of the floor plan are omitted. In the image illustrated in FIG. 13, information that is the result of the check processing is displayed on the floor plan, and in this example, the floor, importance, comments, etc. related to the target of the check processing are displayed in a table format. For example, in the floors "2nd floor" and "3rd floor," a comment is displayed saying "Please place beams of B3 or more on both sides of the escape hatch in the roof balcony section," and the level of this comment is indicated as "important." This comment is the result of prohibition process 3 being executed, and "beams of B3 or greater" refers to the group consisting of "G1, G3, G7, G8, G10, B1, B3, E1, E2" in the examples of Figures 10 to 12 mentioned above. When prohibition process 1 is executed, for example, a comment stating "Please place beams of G9, G1, or G3 on both sides of the escape hatch in the full flat balcony area" is displayed, and when prohibition process 2 is executed, for example, a comment stating "One side of the beams next to the escape hatch in the full flat balcony area must be a G9 beam" is displayed.

In the example image shown in FIG. 13, among the lines used in the check process (lines moved in step S6), those that resulted in an error are displayed on the floor plan with dashed lines. By displaying the lines that resulted in an error on the floor plan, the designer can clearly recognize the locations where the horizontal members should be checked for their placement and type. The information displayed as the check results in FIG. 13 is stored in the check result database 114.

The horizontal material placement check process is executed in this manner.

As described above in detail, the design support device 1 etc. disclosed in the present application determines whether a long horizontal member is appropriately placed on the same floor as an opening in a horizontal plane of a building by moving a line segment obtained from the area that the opening occupies in a plan view a specified distance. This provides excellent effects such as being able to determine prohibitions related to the placement of long horizontal members and support the design of buildings.

The present invention is not limited to the embodiment described above, and can be implemented in various other forms. Therefore, such embodiments are merely illustrative in all respects and should not be interpreted as being restrictive. The scope of the present invention is indicated by the claims, and is not bound by the text of the specification. Furthermore, all modifications and changes that fall within the equivalent scope of the claims are within the scope of the present invention.

For example, in the above embodiment, the horizontal surface of the building is the floor of a balcony, the target opening is an escape hatch, and the long horizontal member is a beam. However, the present invention is not limited to this, and can be expanded to cover a variety of horizontal surfaces, openings, and horizontal members.

In addition, in the above embodiment, the design support device 1 is directly operated by the designer, but the present invention is not limited to this, and can be deployed in various forms, such as installing the design support device 1 as a web server computer on the communication network NW and providing web services from the design support device 1 to a terminal device operated by the designer.
