Description

The present invention relates to a design user terminal, a design support system, a design support method, and a program.

In architectural design, the first step is to decide on the layout of the building, taking into consideration the site conditions and surrounding environment, and then design the interior and exterior, floor plan, decoration, etc. In this design, not only two-dimensional drawings but also three-dimensional drawings including perspective drawings are created by using a commonly used CAD (Computer-aided design). For buildings designed using this design, structural design is performed to set the foundation and frame, and set the specifications, shapes, and placement of columns, beams, walls, etc., so as to meet safety performance against snow accumulation, earthquakes, etc. This is done after the architectural design. In addition, in parallel with this structural design, or after the structural design, facility design is performed to set up air conditioning equipment for a comfortable indoor environment, sanitary equipment that connects to water and sewage systems, and electrical equipment for locating outlets and lighting. be exposed. The design of the building is completed after the design, structural design, and facility design are changed multiple times while each designer shares information with each other.

Regarding designed buildings, in addition to three-dimensional drawings of the building, drawings such as floor plans (including floor plans), elevation drawings (including framework drawings), and equipment plans for each floor (hereinafter referred to as these) Various drawings (referred to as structural drawings) are prepared and submitted as building certification application documents to a building certification application agency, and after the building certification application documents are checked by the building certification agency, the confirmation application is approved.

After the confirmation application is approved, the construction contractor will conduct a detailed design for the structural design up to the above confirmation application process, and create construction drawings etc. with the above structural drawings revised. Ru. In some cases, all designs from structural design to implementation design are performed by a single house manufacturer, etc. In this case, the structural design person and the construction contractor (detailed design person) Become a designer in the department in charge at a manufacturer, etc.

By the way, in the design of each stage of the building mentioned above, it is possible to share information about the building among designers, architects, construction supervisors, construction contractors, etc. using a BIM (Building Information Modeling) model. It is being done. Here, a BIM model is information about the shape in a virtual three-dimensional space, materials, dimensions, location, etc. of the building blocks (also called objects, including beams, columns, walls, etc.). It is a three-dimensional model that has information regarding (these are collectively referred to as "specification information"). Using this BIM model, you can create 3D drawings of the 3D model viewed from various angles, cut the 3D drawing in various ways, and create floor plans (including floor plans) viewed from various angles. You can create two-dimensional drawings such as elevation drawings (including frame drawings). In other words, each component constituting the three-dimensional model contains various specification information, and this specification information can be changed, modified, or added, and a history of changes, additions, etc. can be kept.

Here, an information management system using the above-mentioned BIM has been proposed. Specifically, it is an information management system that includes an information processing terminal used by a user and a server device that is communicably connected to the information processing terminal via a network. Here, the server device stores shape information and specification information of an object in association with the object, and stores work information in which an object is associated with a work item related thereto, and resource information in which a work item is associated with a resource item related thereto. a control unit that acquires the information requested by the user using the information processing terminal based on the shape information, specification information, work information, and resource information; and a communication section for transmitting data to an information processing terminal. The information processing terminal also has a display unit that displays a predetermined screen to the user using the information processing terminal based on information requested by the user using the information processing terminal received from the server device via the network. We are prepared.

Japanese Patent Application Publication No. 2013-164681

According to the information management system described in Patent Document 1, information regarding buildings can be managed appropriately and users can easily obtain necessary information. By the way, in design using a BIM model, the BIM model (BIM structural model) created in the structural design process up to the confirmation application is modified as appropriate in the detailed design process performed during the actual construction, and a new model is created. A BIM model (BIM construction model) has been designed. For example, in the case of reinforced concrete underground beams that connect multiple independent reinforced concrete foundations, various methods such as adjusting the level difference between the two independent foundations and adjusting the relationship with the slabs that are constructed integrally with these foundations can be used. Concrete pouring (additional pouring of concrete) is carried out for the purpose of responding to various level and dimensional adjustments. In addition, there are structural members that compose the BIM model from the structural design stage for additional members that include such raised parts, and these structural members include reinforced concrete foundations (independent foundations, etc.) and underground There are beams, steel columns, piles, etc.

At the structural design stage, structural drawings may be created with a certain degree of concrete expansion in mind, but even in such cases, the specification information of the BIM structural model in the structural design process may include The dimensions and levels of structural members are clearly defined.

On the other hand, in the detailed design process, when a new concrete expansion is added, the person in charge of the implementation design completely replaces the specification information of structural members (objects) such as underground beams to which the concrete expansion is added, and The BIM model is recreated as an object with specification information. Therefore, for example, during the detailed design process, the level of the underground beam connected to the independent foundation may be changed from the level during the structural design process, causing problems such as the underground beam not being in the original position. be. Therefore, each time the person in charge of the detailed design replaces the specification information of an object with a raised surface in the detailed design, the person in charge of the detailed design must check whether there are differences in the levels or dimensions of the related structural members between the BIM construction model and the BIM structural model. It was necessary to check whether there were any problems, and even though a BIM model was used, there was a problem that the detailed design required time and effort.

The present invention has been made in view of the above-mentioned problems, and even when additional members are added to structural members in the detailed design process, it is possible to suppress checks by the person in charge of the detailed design. The purpose is to provide user terminals, design support systems, design support methods, and programs.

In order to achieve the above object, one aspect of the designed user terminal according to the present invention is as follows:

According to this aspect, specification information regarding structural members constituting a BIM model is stored in the storage unit, and the detection generation unit detects additional members added around the structural members. Specification information regarding the additional member is generated. Therefore, specification information regarding structural members can be shared, for example, from the structural design process to at least the subsequent implementation design process, and then additional members (specification information) can be linked to the structural members. . Therefore, even if additional members such as concrete expansion are added to a structural member in the detailed design process, the person in charge of the detailed design must share the same specification information at the stage of the structural design process regarding the target structural member. However, it becomes possible to specify only the specification information of the additional member. As a result, when an additional member is added in the detailed design process, it is possible to significantly suppress checks by the person in charge of the detailed design regarding whether or not the specification information of the structural member has been changed. This effect is also enjoyed by the person in charge of modifying the BIM model in each process after the detailed design process, including the construction process, completion process, and post-completion process (maintenance process).

Here, the design user terminal includes a structural design user terminal, a detailed design user terminal, etc., both of which are formed by a personal computer, but the addition of additional members and their detection are mainly performed at the detailed design user terminal.

The additional member is detected by specifying that the additional member is .

For structures connected by beams, where a concrete extension is often added to the foundation or underground beam, the specification information of structural members is shared from the structural design process to at least the subsequent implementation design process. be able to. Therefore, it is possible to significantly suppress checks by a person in charge of implementation design and the like as to whether or not there has been a change in the specification information of the structural member.

Here, in addition to the column main body formed of a steel section such as a square steel pipe or H-shaped steel, a steel frame column includes an anchor plate attached to the lower end of the column body, and an anchor that protrudes downward from the anchor plate. Bolts etc. may be included. Conventionally, the presence or absence of interference between anchor bolts buried in the foundation and beam reinforcements or foundation reinforcing bars anchored to the foundation from underground beams was checked, for example, during the construction process after the detailed design process. was. At the structural design stage, steel columns, which are structural members, include specification information for anchor bolts, etc., so that the specification information for the columns, including the anchor bolts, can be shared continuously from the structural design process. From this, it is possible to verify and confirm the presence or absence of interference between anchor bolts and various types of reinforcement.

According to this aspect, the structural design user terminal is given the modification authority to modify the specification information of structural members, and the detailed design user terminal is given the modification authority to modify the specification information of the additional members, so that the BIM structure This reduces the possibility that the specification information of structural members included in the model will be modified or changed without permission by a person in charge of implementation design who modifies the BIM model after structural design. This makes it possible for each person in charge of designing to share the specification information of the structural member from the structural design process to at least the subsequent implementation design process. Here, the form in which "modification authority" is granted includes, for example, a structural design person placing a lock (pin) on a structural member, so that a subsequent implementation design person, etc. may attempt to modify the structural member. This includes the form in which an alarm is issued when a situation occurs.

Further, one aspect of the design support method according to the present invention is

[Design support system according to embodiment]
First, with reference to FIG. 1, an example of a design support system according to an embodiment will be described. Here, FIG. 1 is a diagram showing an example of the overall configuration of a design support system according to an embodiment.

The design support system 40 is formed by connecting the design user terminal 10 and the shared server 20 via the network 30. The design user terminal 10 includes an architectural design user terminal 10A, a structural design user terminal 10B, an equipment design user terminal 10C, a detailed design user terminal 10D, etc., and also includes an estimation user terminal, a construction planning user terminal (all of which are not shown) may include a variety of user terminals, such as

The network 30 includes a public network such as the Internet, a wireless network such as a mobile phone network, a dedicated network such as a VPN (Virtual Private Network), a LAN (Local Area Network), and the like.

Here, the design user terminal 10 and the shared server 20 have a closed network in which information is shared only within a company such as a house builder, as well as an open network in which information can be shared with external organizations. It is a form that has.

Regardless of the form, access authority is required to access the shared server 20, and only user terminals that have been granted access authority can access the shared server 20, and various data stored on the shared server 20. can be shared. For example, the BIM model described below is stored in the shared server 20 at each design stage, and a design user terminal or an external organization that is given access authority accesses the shared server 20 and stores the BIM model in the shared server 20. Users can import BIM models currently available on their own terminals, or upload BIM models created on their own terminals to the shared server 20.

Here, in addition to data storage, the shared server 20 may be a cloud server that allows a plurality of users to share various application software. For example, the design user terminal 10 and an external agency terminal (not shown) may use common application software to send and receive BIM data, or when multiple BIM data are sent and received at different times, two arbitrary timings may be used. It may also be possible to compare BIM data of different types of BIM data with each other. Note that the "external agency terminal" may include, in addition to the confirmation application agency terminal, a material and equipment supply manufacturer terminal owned by a material and equipment supply manufacturer that collaborates in the stages of facility design, construction planning, etc.

The design user terminal 10A, the structural design user terminal 10B, the equipment design user terminal 10C, and the detailed design user terminal 10D are used by a design designer, a structural designer, a facility designer, and a detailed designer, respectively. It is a terminal, and is formed by a personal computer, tablet, etc.

BIM models include a BIM design model designed by a person in charge of architectural design on the design user terminal 10A during the planning stage of a building, a BIM structural model designed by a person in charge of structural design on the structural design user terminal 10B, and a BIM structural model designed by a person in charge of structural design on the structural design user terminal 10B. Includes BIM construction models designed by design personnel. At the planning stage, by looking at image data (BIM design model) of a three-dimensionally modeled building, it is possible to directly imagine the appearance, layout design, etc. of the building. In addition, at the facility design stage, we take into account the comfort of the living space by simulating heat flow (flow of wind, air, etc.) inside the building and considering the relationship between lighting placement and the light environment. It is possible to create a design based on Furthermore, at the structural design stage and construction planning stage, by checking 3D images, it is possible to check for interference with equipment, steel frames, piping, etc., and to clearly see details that are difficult to see in 2D drawings. can be grasped.

In the detailed design user terminal 10D that constitutes the design support system 40, for example, in the detailed design stage before the actual construction, the detailed design person performs various types of information that make up the BIM structural model for the BIM structural model that has already been applied for confirmation. If an object has additional members such as roofs for structural members such as foundations and underground beams, the specification information for the additional members can be created while maintaining (retaining) the specification information of the structural members at the structural design stage. , a BIM construction model is designed while linking additional members to the relevant structural member. The BIM construction model designed in this way is then sent to the shared server 20 and stored, and the BIM model is modified in each process during the subsequent construction process, completion process, and post-completion process (maintenance process). Applies to personnel. In addition, in the detailed design process, if the dimensions of additional members added to the structural members are large and weight etc. cannot be ignored, the person in charge of structural design imports the BIM construction model into the structural design user terminal 10B and converts it into a BIM construction model. Based on this, structural calculations are performed again to verify structural stability.

Here, the structural design user terminal 10B is given modification authority to modify the specification information of structural members, and the detailed design user terminal 10D is given modification authority to modify the specification information of additional members. desirable. This eliminates the possibility that the specification information of structural members included in the BIM structural model will be modified or changed without permission by a person in charge of implementation design who modifies the BIM model after structural design.

In the following description, a method for designing a BIM model (BIM construction model) in the design user terminal 10 will be described, mainly keeping in mind the implementation design user terminal 10D as the design user terminal 10.

[Design user terminal according to embodiment]
Next, an example of the design user terminal according to the embodiment will be described with reference to FIGS. 2 to 8. Here, FIG. 2 is a diagram showing an example of the hardware configuration of a computer, and FIG. 3 is a diagram showing an example of the functional configuration of the design user terminal according to the embodiment.

As shown in FIG. 2, the design user terminal 10 is an information processing device such as a personal computer (PC) or a workstation (WS), and the shared server 20 is an information processing device consisting of a server. Both are configured by the computer shown in FIG.

A computer such as the design user terminal 10 includes a CPU (Central Processing Unit) 102, a main storage device 104, an auxiliary storage device 106, a communication IF (interface) 108, and an input/output IF 110 that are interconnected by a connection bus 112. ing. The main storage device 104 and the auxiliary storage device 106 are computer-readable recording media. Note that the above components may be provided individually, or some components may not be provided.

The CPU 102 is also called an MPU (Microprocessor) or a processor, and the CPU 102 may be a single processor or a multiprocessor. The CPU 102 is a central processing unit that controls the entire design user terminal 10 and the like made up of a computer. For example, the CPU 102 develops a program stored in the auxiliary storage device 106 in an executable manner in the work area of the main storage device 104, and controls peripheral devices through the execution of the program, thereby executing functions that meet a predetermined purpose. I will provide a.

The main storage device 104 stores computer programs executed by the CPU 102, data processed by the CPU 102, and the like. The main storage device 104 includes, for example, flash memory, RAM (Random Access Memory), and ROM (Read Only Memory). The auxiliary storage device 106 stores various programs and various data on a recording medium in a readable and writable manner, and is also called an external storage device. The auxiliary storage device 106 stores, for example, an OS (Operating System), various programs, various tables, and the like. The OS includes, for example, a communication interface program that exchanges data with an external device connected via the communication IF 108. External devices include, for example, information processing devices such as personal computers (PCs), workstations (WS), servers, and mobile terminals connected to a network, external storage devices, and the like.

The auxiliary storage device 106 is used, for example, as a storage area to supplement the main storage device 104, and stores computer programs executed by the CPU 102, data processed by the CPU 102, and the like. The auxiliary storage device 106 is a silicon disk including a nonvolatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD) device, a solid state drive device, or the like. Further, as the auxiliary storage device 106, a removable recording medium drive device such as a CD drive device, a DVD drive device, and a BD drive device is exemplified. Examples of removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memories, and SD (Secure Digital) memory cards.

The communication IF 108 is an interface with the network 30 to which the design user terminal 10 and the like are connected. The communication IF 108 transmits the BIM structural model designed by the structural design user and the BIM construction model designed by the implementation design user to the shared server 20 via the network 30.

The input/output IF 110 is an interface that inputs and outputs data with devices connected to the design user terminal 10 and the like. For example, a keyboard, a pointing device such as a touch panel or a mouse, an input device such as a microphone, etc. are connected to the input/output IF 110. The design user terminal 10 and the like receive operation instructions and the like from an operator who operates an input device via the input/output IF 110.

Further, the input/output IF 110 is connected to, for example, a display device such as a liquid crystal display (LCD) or an organic EL panel (electroluminescence), an output device such as a printer, or a speaker. The design user terminal 10 and the like output data and information processed by the CPU 102 and data and information stored in the main storage device 104 and the auxiliary storage device 106 via the input/output IF 110.

As shown in FIG. 3, the design user terminal 10 provides various functions of at least a communication section 120, an input/output section 122, a design section 124, a detection generation section 126, and a storage section 128 by executing a program by the CPU 102. . Note that at least a part of the above processing function may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), etc. Similarly, at least a part of the above processing function may be provided by an FPGA (Field-Programmable Gate). It may also be a dedicated LSI (large scale integration) such as an array), a numerical arithmetic processor, an image processing processor, or other digital circuits.

The communication unit 120 transmits the BIM construction model created at the design user terminal 10 to the shared server 20, receives the BIM structural model stored in the shared server 20, and stores it in the storage unit 128.

The input/output unit 122 accepts data transmitted and received by the communication unit 120 and outputs and displays the data on a display device such as a liquid crystal display included in the design user terminal 10, or displays a BIM construction model on a display device based on a command from the execution design user. Display the output in .

Autodesk Revit (registered trademark) (manufactured by Autodesk) or the like is installed in the storage unit 128 as BIM software, and when the software is activated in the design unit 124, a BIM structural model is displayed. In the detailed design, the practical design user adds additional members, such as inflatables, to various structural members constituting the BIM structural model, if any.

Here, the structural members include, for example, reinforced concrete foundations (independent foundations, etc.), underground beams, steel-framed columns, piles, and the like. On the other hand, the additional member includes, for example, a concrete slab. A structural design user may add inflating in advance to some of the structural members constituting the BIM structural model.

The storage unit 128 stores specification information of objects including structural members that constitute the BIM structural model. For example, if an underground beam is used as an example of a structural member, the storage section 128 stores information on the top level, height, and width of a plurality of underground beams along each street (X street, Y street). Specification information regarding etc. is stored.

During the actual construction, if there are raised concrete parts above or to the sides of various underground beams or foundations, the raised parts are added to each structural member that makes up the BIM structural model by the implementation design user. As a result, a BIM construction model will be designed.

With conventional application software for BIM model design, when a raised part is added to an arbitrary structural member (for example, an underground beam), the person in charge of the implementation design must obtain specification information regarding the target structural member. The specification information in the original BIM design model was completely replaced, and a BIM construction model was created as a new structural member, including the raised area. Therefore, due to the replacement of this structural member, the specification information of the structural member that was set at the structural design stage is often changed at the detailed design stage, and when this specification information is changed, the level of the structural member There were problems such as the changes being made. Therefore, the person in charge of the implementation design needed to carefully check in the BIM construction model whether the level of the structural member, etc. had shifted after replacing the specification information as a structural member that included additional members. .

On the other hand, in the design user terminal 10, when an additional member is added to a structural member, the original specification information of the structural member (the specification information of the structural member set at the structural design stage) is maintained. We decided to individually set the specification information for the added additional members and link them to the structural members.

Specifically, the design user terminal 10 is provided with a detection generation unit 126, and by operating the detection generation unit 126, additional members around the structural member are detected, and specification information of the detected additional members is stored. At the same time, the additional member is linked to the structural member to which it is attached. Here, FIG. 4 shows one display screen that is displayed on the screen of a personal computer when the application software for BIM model design is started.

After identifying the underground beam to which the expansion is added in the BIM construction model, the person in charge of the implementation design clicks the "Beam expansion" icon in the tool menu TM on the display screen shown in FIG. 4. By clicking this icon, the display screen shifts to the screen shown in FIG. 5. Here, FIG. 5 is a diagram showing a cross section perpendicular to the longitudinal direction of the underground beam selected by the person in charge of the implementation design together with a side surface of the independent foundation to which the underground beam is connected.

Above the independent foundation F, a raised part FU with a height of 250 mm is set, and in order to correspond to the addition of the raised part FU to the independent foundation F, in the detailed design process A raised part FUU is added above the , and an raised part FUS is added to the right side of the raised part FUU. However, by simply adding members, it is not clear at all whether the raised portions FUU and FUS are part of the underground beam FG, or whether they are members different from the underground beam FG. Therefore, by operating the detection generation unit 126, raised portions FUU and FUS different from the underground beam FG are detected around the underground beam FG, which is a structural member. More specifically, the raised portions FUU and FUS are detected as members different from the underground beam FG and linked to the underground beam FG.

An example of the detection method is shown in FIGS. 6 and 7. Here, FIG. 6 is a diagram illustrating a method for detecting the side raised portion FUS in the detection generation unit 126, and FIG. 7 is a diagram for explaining a method for detecting the upper raised portion FUU in the detection generation unit 126. It is a diagram.

As shown in Figure 6, if the independent foundation F1 located at the point of X1 street and Y1 street and the independent foundation F2 located at the point of X2 street and Y1 street are connected by underground beam FG1, The detection generation unit 126 first creates a cross-sectional center line CL1 in the width direction of the underground beam FG1 based on the specification information of the underground beam FG1 stored in the storage unit 128. In the example shown in FIG. 6, the cross-sectional center line CL1 and the Y1 line match.

Next, the width of the underground beam FG1 is specified in the longitudinal direction along the cross-sectional center line CL1. Since the width: B of the underground beam FG1 has already been stored in the storage unit 128 as specification information, starting from the end on the independent foundation F1 side, first, move B/2 downward from the cross-sectional center line CL1. The line is scanned until it reaches the independent foundation F2. Through this scanning, it is detected that no raised portion exists below the cross-sectional center line CL1.

Next, starting from the end on the independent foundation F1 side, a line B/2 is scanned upward from the cross-sectional center line CL1 until it reaches the independent foundation F2. Through this scanning, two lines are detected: a line of B/2 above and a line of ΔB further above it.

The detection generation unit 126 detects the area between the B/2 line and the ΔB line as a raised part FUS on the side different from the underground beam FG1, and stores the specification information of the raised part FUS in the storage part 128. Store.

In this way, the detection generation unit 126 stores the specification information of the raised portion FUS added to the side of the underground beam FG1 while holding the specification information of the underground beam FG1.

Similarly, as shown in FIG. 7, a cross-sectional center line CL2 in the height direction of the underground beam FG1 is created based on the specification information of the underground beam FG1 stored in the storage unit 128.

Next, the height of the underground beam FG1 is specified in the longitudinal direction along the cross-sectional center line CL2. Since the height: H of the underground beam FG1 is already stored in the storage unit 128 as specification information, first, from the end on the independent foundation F1 side, from the cross-sectional center line CL2 downwardly H/ 2 line is scanned until it reaches the independent foundation F2. Note that a crushed stone layer J and a sacrificial concrete layer K are set below the underground beam FG1, but by this scanning, lines other than the crushed stone layer J and the sacrificial concrete layer K are found below from the cross-sectional center line CL2. Since it does not exist, it is detected that there is no puffed portion below.

Next, starting from the end on the independent foundation F1 side, a line of H/2 is scanned upward from the cross-sectional center line CL2 until it reaches the independent foundation F2. Through this scanning, two lines are detected: the H/2 line above and the ΔH line above it.

The detection generation unit 126 detects the area between the H/2 line and the ΔH line as the raised part FUU above the underground beam FG1, and stores the specification information of the raised part FUU in the storage part 128. do.

In this way, the detection generation unit 126 stores the specification information of the raised portion FUU added above the underground beam FG1 while retaining the specification information of the underground beam FG1, and as shown in FIG. The specification information of the raised portions FUU and FUS is stored, including the specification information of the raised portion FUS described above. That is, while the specification information of the underground beam FG1 is maintained, the information is stored with raised portions FUS and FUU of ΔB added to the sides and ΔH added above. In FIG. 7, piles P1 and P2 are shown below the independent foundations F1 and F2, respectively, and steel columns C1 and C2 are shown above the independent foundations F1 and F2, respectively.

In this manner, according to the design user terminal 10, the detection generation unit 126 detects additional members added around the structural member and generates specification information regarding the additional member. can be shared, for example, from the structural design process to at least the subsequent implementation design process, and then additional members (specification information thereof) can be linked to the structural members. Therefore, even if additional members such as concrete expansion are added to a structural member in the detailed design process, the person in charge of the detailed design must share the same specification information at the stage of the structural design process regarding the target structural member. However, it becomes possible to specify only the specification information of the additional member. As a result, when an additional member is added, it is possible to significantly suppress the need for a person in charge of implementation design to check whether or not the specification information of the structural member has been changed.

Next, with reference to FIG. 8, a case will be described in which the anchor plate and anchor bolt provided on the column base are applied to the BIM model from the structural design stage when the structural member is a column of steel frame construction. Here, FIG. 8A is a perspective view of a column base showing an example of a column including an anchor bolt, and FIG. 8B is a mode in which the anchor bolt shown in FIG. 8A is visually recognized when it is buried in an independent foundation. It is a figure shown by.

An anchor plate AP is connected to the lower end of the main body of the column C by welding to a column C of a steel structure such as a square steel pipe, and a plurality of anchor bolts AB (four in the illustrated example) protrude downward from the anchor plate AP. Anchor plate AP is installed at the top of independent foundation F, and anchor bolt AB is buried inside independent foundation F, thereby fixing column C to independent foundation F supported by pile P. It will be planned. Therefore, there is a risk that the anchor bolt AB buried in the independent foundation F may interfere with the beam reinforcements fixed to the independent foundation F from the underground beam FG, the reinforcing bars of the independent foundation F (none of which are shown), etc. Therefore, it is necessary to verify the presence or absence of these interferences. In conventional design, this verification of the presence or absence of interference is performed, for example, at a stage such as the construction process after the detailed design process.

Therefore, in the structural design stage, by including the specification information of the anchor bolt AB in the specification information of the steel frame column C, which is a structural member, the specification information of the column C including this anchor bolt AB is continued from the structural design process. This makes it possible to verify and confirm the presence or absence of interference between anchor bolts AB and various reinforcements from the stage of the structural design process.

[Design support method according to embodiment]
Next, with reference to FIG. 9, an example of the design support method according to the embodiment will be described. Here, FIG. 9 is a flowchart of an example of the design support method according to the embodiment.

First, a person in charge of implementation design performs an addition process to the BIM structural model of the already designed building, in which additional members to be added around each structural member are added at the time of implementation. Here, each structural member constituting the BIM structural model of the building has its own unique specification information (step S200). Here, as already explained, structural members include foundations, underground beams, columns, piles, etc., and additional members include underground beams, concrete slabs added to the foundation, and the like.

Next, in each structural member to which an additional member has been added, additional members added around the structural member are detected based on the specification information of each structural member, and specification information regarding the detected additional member is generated. Execute the process. (Step S210).

As explained with reference to FIGS. 6 and 7, in this detection generation step, the cross-sectional center lines CL1 and CL2 of the structural member FG1 are created based on the specification information of the structural member FG1, and the cross-sectional center lines CL1 and CL2 are The width or height of the structural member is specified in the longitudinal direction along the structural member, and areas where the width or height increases compared to the specification information possessed by the structural member are identified as additional members FUS and FUU. By doing so, the additional members FUS and FUU are detected.

In the detection generation process, the additional members FUS and FUU added around the structural member FG1 are detected, and specification information regarding the additional members FUS and FUU is generated. Therefore, the specification information regarding the structural member FG1 is generated based on, for example, structural design. It can be shared from the process to at least the subsequent implementation design process, and then additional members (specification information thereof) can be linked to the structural member FG1. Therefore, in the detailed design process, even if additional members FUS and FUU such as concrete expansion are added to the structural member FG1, the person in charge of the detailed design will It becomes possible to specify only the specification information of the additional members FUU and FUS while sharing the specification information. As a result, when the additional members FUU and FUS are added, it is possible to significantly suppress checks by the person in charge of implementation regarding whether or not the specification information of the structural member FG1 has been changed.

It should be noted that other embodiments may be adopted in which other components are combined with the configurations listed in the above embodiments, and the present invention is not limited to the configurations shown here. In this regard, changes can be made without departing from the spirit of the present invention, and can be appropriately determined depending on the application form.
