As a technique related to a building design system, for example, the technique described in Patent Literature 1 is known.

Japanese Patent Laid-Open No. 2004-100000 includes a storage unit that stores information about a large number of structural members, and a modeling unit that arranges structural members selected based on information input by a designer at predetermined positions in a work space. A design system is disclosed. In addition, the modeling unit determines the possibility of joining between one structural member and another structural member, and when it is determined that joining is possible, the joining part is displayed in different colors on the three-dimensional image. do. In this way, with the technique described in Patent Document 1, the designer can arrange the structural members while confirming the fitting (possibility of joining) of the structural members.

However, in the technique described in Patent Document 1, although the modeling unit determines the possibility of joining between structural members, if it is determined that the joining is not possible, the designer himself cannot create a structure that can be joined at the joint. It is necessary to select the member again. In this case, the designer must determine (classify) the configuration of the joints of the structural members (joint mode, position of joint holes, quantity, etc.) and determine the structural members that can be joined at the joints. , which is disadvantageous in that the design work is complicated.

First, an overview of a design system 1 according to this embodiment will be described with reference to FIG.

The design system 1 is for designing a building, and particularly for designing a frame constructed by connecting structural members such as columns and beams. In particular, the design system 1 according to this embodiment can automatically design a configuration at a connection point P between a structural member and another member (such as another structural member).

The configuration of the design system 1 according to this embodiment will be described below.

The design system 1 mainly includes an input device 10 , a display device 20 and a control device 30 .

The input device 10 is for inputting various information to the control device 30 . The input device 10 is configured by a terminal that can be operated by a worker (designer). For example, a keyboard, a touch panel, or the like can be used as the input device 10 .

The display device 20 is for displaying various information (characters, drawings, etc.) received from the control device 30 . For example, a liquid crystal monitor, a touch panel, or the like can be used as the display device 20 .

The control device 30 performs various calculations, storage, and the like based on various information. The control device 30 is configured by a storage unit such as a RAM, a ROM, and an HDD, a CPU, and the like. For example, a personal computer or the like can be used as the control device 30 .

The control device 30 is functionally composed of an initial processing section 31 that mainly performs initial design processing, a virtual space arrangement section 32 that arranges structural members in the virtual space, and a method of connecting structural members arranged in the virtual space. connection method determination unit 33, strength determination unit 34 that determines the strength at the connection point P of the structural member, connection method determination unit 35 that determines the shape of the member based on the strength of the connection point P, and each designed member is provided with a model allocation unit 36 or the like that allocates the corresponding model. Detailed functions of the respective units (initial processing unit 31, etc.) will be described together with the operation of the design system 1. FIG.

The operation of the design system 1 (the design method using the design system 1) will be specifically described below.

In step S101 of FIG. 2, the initial processing unit 31 performs initial processing of design.

As an initial process, the initial processing unit 31 first acquires information on planning and designing that has been performed in advance. The planning and design information generated by the planning and design is input in advance to the control device 30 in a format such as CSV. The initial processing unit 31 stores the acquired plan design information in a storage unit (not shown) of the control device 30 . In planning and design, the product classification (product classification) of the building to be designed, the shape (cross-sectional shape, etc.) of the structural members that make up the frame, the type (large beam, small beam, canch, column, etc.), arrangement coordinates, etc. has been decided. Planning and design can be executed using various CAD software suitable for the planning and design. The initial processing unit 31 acquires various kinds of information such as product categories and cross-sections determined in planning and design.

Also, as an initial process, the initial processing unit 31 assigns (numbers) a different number (SEQ number (sequence number)) to each acquired structural member, and stores it in the storage unit. By assigning a different SEQ number to each structural member, it becomes possible to distinguish (identify) the structural member based on the SEQ number.

In step S102, the virtual space arrangement unit 32 arranges and assembles the structural members in the virtual space.

The virtual space placement unit 32 places structural members in a three-dimensional virtual space using three-dimensional CAD software. In this embodiment, the coordinates in the virtual space are defined by a three-dimensional orthogonal coordinate system consisting of the X-axis, Y-axis and Z-axis. At this time, the virtual space arranging unit 32 arranges each structural member in the virtual space in the order of the SEQ number based on the various information (such as the arrangement coordinates of the structural member) acquired in step S101. FIG. 3 shows how each structural member (beam 2, column 3, etc.) is arranged in the virtual space.

Here, the coordinates of the structural member mean the coordinates at the core (module core) of the structural member. Therefore, when the structural members are arranged based on the coordinates, the structural members are arranged in a state where they interfere with each other at the portions where the structural members are connected (connection points P described later).

4 and 5 show how structural members (beams 2) are arranged according to coordinates and interfere with each other at connection points P. FIG. 4 and 5 show how the beams 2 are arranged along the structural plane (horizontal structural plane (XZ plane)). FIG. 4 shows an example in which ends of four beams 2 are connected to each other. Also, FIG. 5 shows an example in which an end portion of another beam 2 is connected to a longitudinal middle portion (middle portion) of one beam 2 . As shown in FIGS. 4 and 5, the structural members are arranged to overlap (interfere) with each other at the connection point P. As shown in FIGS.

The virtual space placement unit 32 also stores the type, SEQ number, cross-sectional dimension information, etc. of the structural member placed in the virtual space as attributes of the structural member. 4 and 5 also show attributes of each structural member (beam 2). For example, in FIG. 4, the attributes of the four beams 2 shown in FIG. Number: A021, Type: Large beam, Cross-sectional dimension information: H-200×100×4.5/9”, “SEQ number: B023, Type: Small beam, Cross-sectional dimension information: H-200×100×3. 2/4.5" and "SEQ number: C002, type: cantilever, cross-sectional dimension information: H-250×100×3.2/6".

Note that the control device 30 causes the display device 20 to display an image of a virtual space (such as the image shown in FIGS. 4 and 5) used in the three-dimensional CAD software. The operator can visually confirm the state of the design by the design system 1 by viewing the image on the display device 20 .

In step S103 of FIG. 2, the virtual space layout unit 32 generates connection points between structural members.

The virtual space placement unit 32 generates (forms) intersection points (connection points P) at portions where structural members interfere with each other (portions where structural members are connected) from the result of arranging structural members in the virtual space. Further, the virtual space layout unit 32 stores information about structural members connected from a plurality of directions to the generated connection point P as attributes of the connection point P concerned.

For example, in the example shown in FIGS. 4 and 5, information on structural members (beams 2) connected to each connection point P is obtained from four directions parallel to the X-axis and Z-axis along the structural plane (horizontal structural plane). , is stored as an attribute of each connection point P. Attributes of each connection point P are also displayed in FIGS. For example, FIG. 4 shows "direction 1: A021 large girders, direction 2: C002 cantilever, direction 3: A014 large girders, direction 4: B023 small girders" as attributes of the connection point P shown in FIG. . In this embodiment, as shown in FIG. 6, of the directions toward the connection point P along the structural plane, the directions parallel to the X axis are "direction 1" and "direction 3", and the direction parallel to the Z axis. are defined as "direction 2" and "direction 4", respectively.

In step S104 of FIG. 2, the connection method determination unit 33 makes a determination regarding the connection position (connection point P). More specifically, the connection method determining unit 33 classifies the type of the connection point P based on the information (attribute) regarding the connection point P. As shown in FIG. Here, the type of connection point P means the type of connection mode of a plurality of structural members connected at the connection point P (which parts of the structural members are connected to each other).

Specifically, the connection method determination unit 33 refers to the attribute of the connection point P, and combines the SEQ numbers of the structural members (identical or). That is, the connection method determination unit 33 determines whether the SEQ numbers of the structural members connected to the connection point P from "direction 1" and "direction 3" are the same, and whether the structure connected from "direction 2" and "direction 4" is the same. It is determined whether the SEQ numbers of the members are the same.

When the SEQ numbers of the structural members existing on the diagonal line across the connection point P are all different, the connection method determination unit 33 selects each of the plurality of structural members at the connection point P as shown in FIG. It can be determined that the ends are connected. Such connection of the ends of the structural members is referred to as "end-to-end connection".

On the other hand, when there is a structural member with the same SEQ number that exists on a diagonal line with the connection point P therebetween, the connection method determination unit 33 selects one It can be determined that a structural member is arranged. That is, in this case, as shown in FIG. 5, it can be determined that, at the connection point P, the middle portion (middle portion) of one structural member is connected to the end portion of another structural member. Such connection between the middle portion (intermediate portion) and the end portion of the structural member is referred to as "intermediate portion connection".

In this manner, the connection method determination unit 33 classifies the types of the connection points P and stores them as information about the connection points P in the storage unit.

In step S105 of FIG. 2, the connection method determination unit 33 determines the connection method of the structural member at the connection point P based on the type of the connection point P. As shown in FIG. Here, the connection method means a configuration for connecting structural members. The connection method in this embodiment particularly means a connection member for connecting structural members.

The connection method determining unit 33 checks the type of the connection point P by referring to a table T1 as illustrated in FIG. 7 stored in the storage unit. Table T1 shows connection methods (connection members) and the like according to product categories and types of connection points P. FIG. It should be noted that the relationship between product categories and connection methods, etc., as shown in Table T1, is model-approved (registered) in advance for each product.

The connection method determination unit 33 collates the product category of the building obtained in step S101 and the type of connection point P obtained in step S104 with the table T1. Accordingly, the connection method determination unit 33 determines the corresponding connection method (connection member) and offset value.

For example, if the product category is "M1" and the type of connection point P is "end-to-end connection", using Table T1, the connection method (connection member) is set to "joint box" and the offset value is set to "50 mm". can decide.

Here, the offset value is the amount of reduction in the longitudinal dimension of the structural member required according to the connection method. By reducing (retreating) the portion where the structural member interferes with another structural member (the end of the structural member) by the offset value, the interference with the other structural member can be eliminated. Furthermore, a connection member (joint box, etc.) is placed in the space obtained by reducing the structural member by the offset value.

In this manner, the connection method determination unit 33 determines the connection method and the like at the connection point P, and stores the information regarding the connection point P in the storage unit.

Also, the connection method determining unit 33 reduces (retracts) the end of each structural member by the determined offset value. The connection method determining unit 33 reflects the shape of the structural member in the structural member arranged in the virtual space. FIG. 8(a) shows, as an example, a state in which the ends of the beams 2 (see FIG. 4) connected between the ends are reduced (retracted).

Also, the connection method determination unit 33 arranges the determined connection method (connection member) in the virtual space. FIG. 8(b) shows, as an example, a state in which the joint box 5 is arranged at the connection point P of the beams 2 connected end-to-end.

In step S106 in FIG. 2, the strength determination unit 34 determines the strength (connection strength) required for the end portion of the structural member based on the type of the structural member. More specifically, the strength determination unit 34 determines the thickness required for the plate (end plate 4) provided at the end of the structural member.

The strength determination unit 34 refers to a table T2 stored in the storage unit and illustrated in FIG. 9 to determine connection strength. Table T2 shows the connection strength (thickness of the end plate 4) according to the type and location of the structural member.

The strength determination unit 34 displays the type of structural member, the part (whether or not the end of the structural member is the tip), the presence or absence of the connection of the brace (whether or not the brace of the hang balcony is connected), and the like. Match with T2. Based on this, the strength determination unit 34 determines the corresponding connection strength.

Specifically, the strength determination unit 34 checks the information of the structural member to be determined in order from the top row to the bottom row of the table T2. That is, in table T2, the higher the row, the higher the priority. As a result of collation, if there is a corresponding line, the strength determination unit 34 determines that the connection strength (4 mm) described in the line is present. Further, when none of the lines corresponds, the strength determination unit 34 determines that the connection strength is 6 mm as described in the bottom line.

Thus, in the present embodiment (Table T2), the connection strength (thickness) is set to 4 mm only in predetermined cases, and the connection strength (thickness) is set to 6 mm in other cases. Thus, in the present embodiment, the maximum value (maximum strength: 6 mm) of the connection strength (thickness) is set as a standard value, and when the maximum value (maximum strength) is not required, the connection strength (thickness) is set to 4 mm. I am trying to

In addition, in this embodiment (Table T2), priority is set so that the connection strength (thickness) is set to 4 mm if possible. This allows selection of an appropriate connection strength rather than an excessive connection strength.

In this manner, the strength determination section 34 determines the connection strength of the end portion of each structural member and stores the determination result. In addition, the strength determination unit 34 reduces the end portion of the structural member by the thickness of the end plate 4 (4 mm or 6 mm in this embodiment) in order to secure the space for arranging the determined end plate 4. (retreat). The shape of the structural member is reflected in the structural member arranged in the virtual space.

In step S107 in FIG. 2, the connection method determination unit 35 determines the connection method at the end of the structural member based on the type of the structural member. More specifically, the connection method determination unit 35 determines the length of the end plate 4 used for connecting the structural members and the position of the bolts on the end plate 4 .

The connection method determination unit 35 determines the connection method by referring to the relationship between the type, cross section, etc. of the structural member stored in the storage unit and the corresponding connection method (bolt position, etc.). The connection method determination unit 35 determines the type of structural member, the cross section, whether the structural member is for floor assembly, whether the flat roof section on the middle floor is the target, and the type of connecting member to be connected. is determined, and a connection method is determined according to the type of the structural member.

Table T3 in FIG. 10 exemplifies a part of the result of connection method determination by the connection method determination unit 35 . The connection method determination unit 35 acquires the type and cross section of the structural member as input information, and outputs the shape of the end plate 4 (plate length, etc.) as return information.

Here, the connection method in this embodiment specifically means the length of the end plate 4 (plate length), the number of bolts provided on the end plate 4, and the positions of the bolts. . An example of the end plate 4 is shown in FIG. As shown in FIG. 11, the plate length is the length of the end plate 4 in the up-down direction (longitudinal direction (up-down direction in FIG. 11)). The end plate 4 is symmetrically provided with bolts. FIG. 11 illustrates a state in which bolt holes 4a through which bolts are inserted are formed in the end plate 4. As shown in FIG.

The position of the bolt (the position of the bolt hole 4a) is defined by the distance from the top edge of the end plate 4. As shown in FIG. For example, as shown in FIG. 11, when six bolts (bolt holes 4a) are provided in the end plate 4, depending on the distance from the upper end of the end plate 4 (bolt position 1, bolt position 2 and bolt position 3) , the position of the bolt is defined. It should be noted that if the end plate 4 is provided with four bolts, only the bolt positions 1 and 2 will be provided with bolts.

In this manner, the connection method determination unit 35 determines the connection method at the end of each structural member, and stores the result of the determination in the storage unit.

In step S108 of FIG. 2, the connection method determination unit 35 generates the shape of the end plate 4 according to the connection method determined in step S107. Specifically, the connection method determination unit 35 generates (forms) the bolt holes 4 a in the end plate 4 . Also, the connection method determination unit 35 arranges the generated end plate 4 in the virtual space using three-dimensional CAD software. FIG. 12 shows, as an example, how the end plate 4 is arranged at the end of the beam 2 . Further, FIG. 13 shows, as an example, a state in which the end plate 4 is arranged at the end of the beam 2 connected end to end.

In step S<b>109 in FIG. 2 , the connection method determination unit 35 generates the shape of the connection member (the member determined in step S<b>105 ) to be joined to the end plate 4 . Specifically, bolt holes are also generated (formed) in the connection member that is joined to the end plate 4 .

For example, when the end plate 4 is connected to a joint box (joint box 5 shown in FIG. 14), which is a connection member, the connection method determination unit 35 also creates the bolt holes 5a in the joint box 5 . At this time, the connection method determination unit 35 creates the bolt holes 5a at positions corresponding to the bolt holes 4a of the end plate 4 .

In step S110 in FIG. 2, the model allocation unit 36 selects a suitable candidate from among pre-registered candidates for the end plate 4 based on the connection method (shape of the end plate 4, etc.) at the end of each structural member. Allocate the type (model) of the end plate 4 to be used.

The model allocation unit 36 stores the types (models) of a plurality of end plates 4 used for the product, the shape of the end plate 4, and the like for each product category. The model allocation unit 36 refers to the connection method (the shape of the end plate 4, etc.) determined in step S107, and allocates the corresponding type (model) of the end plate 4 stored. .

Table T4 in FIG. 15 exemplifies a part of the result of allocation of the type (type) of the end plate 4 by the type allocation unit 36. As shown in FIG. The model allocation unit 36 acquires the shape of the end plate 4 (plate length, etc.) as input information, and outputs the type of the end plate 4 (plate type) as return information.

Here, the plate type in this embodiment is a number that identifies the type (model) of the end plate 4 . In this embodiment, the type (model) of the end plate 4 to be used is determined for each product category of the building to be designed. Therefore, the model allocation unit 36 determines which model of the end plate 4 the connection method (the shape of the end plate 4, etc.) determined in step S107 corresponds to.

In this way, by linking the end plate 4 to a predetermined model and grasping the number of the end plate 4 using the model, it is possible to improve the efficiency of parts management and manufacturing. .

If there is no corresponding type (model) of the end plate 4, the model allocation unit 36 determines that the end plate 4 should be ordered separately, and stores that effect in the storage unit.

In this way, the model allocation unit 36 allocates the model of each end plate 4 and stores the result in the storage unit.

In step S111 in FIG. 2, the model allocation unit 36 selects a corresponding one of pre-registered connection member candidates based on the type (model) of the end plate 4 of the structural member to be connected at the connection point P. Allocate the type (model) of the connection member.

The model allocation unit 36 refers to the storage unit that stores the types (models) of multiple connection members (joint boxes, etc.) used in the product and the shape of the connection members, etc., for each product category, and performs allocation. conduct. The model allocation unit 36 refers to the type (model) of the end plate 4 allocated in step S110, and allocates the corresponding one from among the stored types (models) of the connection members.

Table T5 in FIG. 16 exemplifies a part of the results of allocation of the types (models) of the connection members (joint boxes in the example of FIG. 16) by the model allocation unit 36. In FIG. The model allocation unit 36 acquires the type (model) of the end plate 4 as input information, and outputs the type (model) of the joint box to which the end plate 4 is connected as return information. More specifically, the type of end plate 4 that is connected to each of the six sides of the joint box draws the type (type) of suitable joint box.

If there is no corresponding joint box type (model), the model allocation unit 36 determines that the joint box should be ordered separately, and stores that fact in the storage unit.

Through the processes from step S101 to step S111 described above, the design system 1 can design a frame configured by connecting structural members. In particular, the design system 1 of the present embodiment designs the connection method and the like (fitting) at the connection point P based on the information on the connection point P between the structural members. can be suppressed.

In the above example, the connection between the beams 2 on the horizontal structural plane was explained as an example, but the design system 1 is not limited to this, and the connection between the structural members on the vertical (vertical) structural plane (for example, between the beams 2 and A similar design is possible for the connection with the pillar 3 and the connection between the pillars 3).

In addition, in the above example, the manner of designing the connection method etc. at the connection point P between structural members was explained, but the design system 1 can also design equipment piping, hardware, etc. in parallel with the design. is.

Specifically, as an initial process, the design system 1 acquires information on facility piping and metal fittings determined by planning and designing performed in advance. Information about the equipment piping and hardware is input to the control device 30 in advance in a format such as CSV. The design system 1 stores the acquired information about the facility piping and the like in the storage unit of the control device 30 . In addition, the design system 1 can reflect the shape required for arranging the facility piping and the like in the structural member. For example, if a hole for inserting an equipment pipe is required in the beam 2, the hole is formed based on information (coordinates, etc.) related to the equipment pipe. Also, if bolt holes for attaching hardware (such as hardware for attaching external wall panels, etc.) to the beam 2 are required, the bolt holes are formed based on information (coordinates, etc.) on the hardware.

As described above, the design system 1 according to this embodiment is

That is, since the design system 1 classifies the connection points P according to the manner of connection, it becomes possible to easily determine the configuration of the connection points P according to the classification, which in turn improves the efficiency of the entire design work. can be planned. In addition, since the connection points P are classified automatically, human error can be suppressed.

Further, the connection point classification means (connection method determination unit 33)

Further, the connection point classification means (connection method determination unit 33)
The connection points P are classified based on whether or not the identification numbers given to the structural members arranged at opposite positions with the connection point P therebetween are the same.
By configuring in this way, the connection points P can be easily classified. In other words, the connection points P can be classified simply by confirming the identification number of each structural member without the need for complicated calculations or the like.

By configuring in this way, it is possible to improve the efficiency of the design work. That is, since the design system 1 classifies the connection points P according to the connection mode and determines the configuration of the connection points P according to the classification, the designer does not need to determine the configuration for each connection point. Therefore, the efficiency of the entire design work can be improved. In addition, since the configuration of the connection point P is determined automatically, human error can be suppressed.

Further, the connection method determination means (connection method determination unit 33)
The configuration of the connection point P is determined in consideration of the classification of the product to be designed (step S105).
By configuring in this way, it becomes possible to determine a more appropriate configuration. That is, when the configuration of the connection point P is determined in advance for each product, it is possible to determine the configuration according to the product.

Further, the connection method determination means (connection method determination unit 33)
A connecting member to be used for connecting the structural members is determined (step S105).
By configuring in this way, it is possible to more effectively improve the efficiency of the design work.

Further, the model allocation unit 36 according to the present embodiment is an embodiment of model allocation means.

Although the embodiment has been described above, the present invention is not limited to the above configuration, and various modifications are possible within the scope of the invention described in the claims.

For example, in the present embodiment, the design system 1 displays the state of design (three-dimensional image) on the display device 20, but the present invention is not limited to this, and the three-dimensional image is not necessarily It does not have to be displayed.

Further, in the present embodiment, the connection point P is classified based on the SEQ number of the structural member connected at the connection point P (step S104), but the present invention is not limited to this. The connection points P may be classified based on information about the structural member (arrangement coordinates, shape, etc.). For example, the connection method determination unit 33 refers to the arrangement coordinates of the structural members, extracts two structural members existing on a diagonal line across the connection point P, and determines whether the shapes, etc. of the structural members are the same. determine whether The connection method determination unit 33 estimates that the two structural members are actually one structural member when the shapes and the like of the two structural members are completely the same. On the other hand, when the shape and the like of the two structural members are not the same, the connection method determination unit 33 presumes that the two structural members are separate and independent structural members. The connection method determination unit 33 can classify the type of the connection point P (end-to-end connection or intermediate connection) based on this estimation result.

In this embodiment, the connection method at the connection point P is determined based on the product category and the type of the connection point P (step S105), but the present invention is not limited to this. It is also possible to determine the connection method based only on the type of point P.
