Description

The present invention relates to a design user terminal and a program.

In architectural design, the layout of the building (architecture) is decided while taking into consideration the site conditions and the surrounding environment, and the design of the interior and exterior, floor plan, decoration, etc. is carried out first. In this design, 2D drawings as well as 3D drawings including perspective drawings are created using the commonly used CAD (Computer-Aided Design). After the design, the structural design is carried out to set the columns and beams that make up the main structure of the building so that it meets safety requirements against snowfall, earthquakes, etc. After this structural design, production design is carried out to create a production model in which each component that will actually be used and produced in the factory is reflected in the model.

Recently, in the design of the above-mentioned buildings, BIM (Building Information Modeling) models are used to share information about buildings among designers and engineers. Here, a BIM model is a three-dimensional model that contains information about the shape in a virtual three-dimensional space of the components that make up a building (also called objects, including beams, columns, walls, etc.), as well as information about the materials, dimensions, placement positions, etc. (collectively referred to as "specification information"). Using this BIM model, it is possible to create three-dimensional drawings of the three-dimensional model viewed from various angles, as well as to cut the three-dimensional drawings in various ways and create two-dimensional drawings such as floor plans (including floor plans) and elevations (including framework drawings) viewed from various angles. In other words, each component that makes up a three-dimensional model contains various specification information, and this specification information can be changed, modified, or added to, and a history of changes, additions, etc. can also be kept.

Incidentally, among the buildings to be designed, buildings in which the construction of the framework, roof, exterior walls, etc. is standardized, and the production process of the components is systemized, are generally referred to as "system buildings." For example, factories, logistics warehouses, and retail stores such as drugstores and convenience stores are given as examples of system buildings.

Here, Patent Document 1 proposes an information management system using the above-mentioned BIM. Specifically, it is an information management system having an information processing terminal used by a user and a server device communicably connected to the information processing terminal via a network. This server device is equipped with a storage unit that stores shape information and specification information of an object in association with the object, stores work information that associates the object with a work item related to it, and resource information that associates the work item with a resource item related to it, a control unit that acquires information requested by a user using the information processing terminal based on the shape information, specification information, work information, and resource information, and a communication unit that transmits the acquired information requested by the user to the information processing terminal that is the request source. In addition, the information processing terminal is equipped with a display unit that displays a predetermined screen to the user using the information processing terminal based on the information requested by the user using the information processing terminal received from the server device via the network.

JP 2013-164681 A

According to the information management system described in Patent Document 1, information about buildings can be appropriately managed, and users can easily obtain the information they need. However, while the fit of each component is standardized in the above-mentioned system architecture, in the creation of a BIM design model for a conventional system architecture, the designer draws the BIM design model while manually inputting information about each component (object) into a design user terminal. This poses the problem that the creation of a BIM design model for a system architecture requires time and effort.

The present invention has been made in consideration of the above-mentioned problems, and aims to provide a design user terminal and program that can efficiently design BIM design models for system buildings in which the fitting of components is standardized.

In order to achieve the above object, one aspect of the design user terminal according to the present invention comprises:
A design user terminal for designing a BIM design model of a building included in a system building,
A storage unit that stores at least structure/use data related to a plurality of types of structures/uses, including the structural framework and use of the building, and exterior material data related to one or more exterior materials specific to each structure/use;
a selection request unit that requests the selection of one of the structures/purposes and one of the exterior materials, and when the one of the structures/purposes and the exterior materials is selected, starts a request screen that further requests the input of building information data related to building information, including plan dimensions and height dimensions of the building;
The present invention is characterized by having a drawing unit that draws the BIM design model based on the input building information data.

According to this aspect, the storage unit stores at least the structure/use data and the exterior material data specific to each structure/use, the selection request unit requests the selection of the structure/use and the exterior material, and further requests the input of building information data such as the floor dimensions of the building, and the drawing unit draws (or automatically arranges) the BIM design model based on the input building information data, thereby eliminating the need to manually input information about objects and enabling efficient design (creation) of the BIM design model. In particular, since the building that is the subject of design by the design user terminal of this aspect is a building included in a system building in which some or all of the fitting between components is standardized, information about the structure/use, which is a representative example of the fitting specific to standardized system buildings, and the exterior material specific to the structure/use is stored in advance in the storage unit and is modeled simply by being selected, this aspect is a terminal suitable for the BIM design model of a system building.

Here, in the "structure/use", the "structure" includes, for example, the structural frame type of steel frame construction, such as one-story or two-story, a structure using single beams, or a structure using truss beams, and the "use" includes logistics warehouses, retail stores such as drug stores and convenience stores, etc. Since the manufacturer and product number of the standard specification exterior material differs depending on the structure/use, a unique single or multiple exterior material data is set for each structure/use and stored in the memory unit. Therefore, when one structure/use is selected in response to the request displayed on the display unit, exterior materials unique to the selected structure/use are listed, and the user is further required to select one exterior material from the multiple exterior materials listed. Note that depending on the structure/use, there may be only one type of exterior material, in which case the presented exterior material will be selected.

The BIM design model drawn in the drawing section is created using a perimeter model that includes exterior columns located on the perimeter and exterior beams (eaves beams, girder beams) that connect adjacent exterior columns, and a roof model that is installed on top of the perimeter model.

The design user terminal in this embodiment includes a personal computer or tablet owned by the design engineer.

In another aspect of the design user terminal according to the present invention,
The roof of the building is a folded plate roof,
The selection request unit is characterized in that it further requests the selection of either a seam fastening type or a lap bolt fastening type among the folded plate roofs.

According to this aspect, for a folded-plate roof, which is a common type of roof for a system building, a choice between a snap fastening method and a bolt fastening method, which are typical examples of fastening methods for a folded-plate roof to a beam, is further required, and in addition to the structural frame and exterior materials, the method of fastening the folded-plate roof to the beam is specified, completing the arrangement of all objects that make up the BIM design model. Here, the snap fastening method refers to a method in which folded plates are folded together and fastened, and the bolt fastening method refers to a method in which the ends of folded plates are fastened together with bolts and nuts.

Moreover, one aspect of the program according to the present invention is
A program for causing a computer that designs a BIM design model of a building included in a system building to execute the following processes:
Store at least structure/use data relating to a plurality of types of structures/uses, including the structural framework and use of the building, and exterior material data relating to one or more exterior materials specific to each structure/use;
launching a request screen for requesting selection of one of the structures/purposes and one of the exterior materials, and when the one of the structures/purposes and the exterior materials is selected, further requesting input of building information data related to building information including plan dimensions and height dimensions of the building;
The method is characterized in that the BIM design model is drawn based on the input building information data.

According to this aspect, a program installed or downloaded to a personal computer or the like stores at least structure/use data and exterior material data specific to each structure/use, requests the selection of structure/use and exterior material, and further requests input of building information data such as the building's plan dimensions. Then, a BIM design model is drawn based on the input building information data, thereby eliminating the need to manually input information about objects and enabling efficient design of a BIM design model.

As can be understood from the above explanation, the design user terminal and program of the present invention can efficiently design BIM design models for system buildings in which the fitting of components is standardized.

[Design User Terminal According to the Embodiment]
An example of a design user terminal according to an embodiment will be described with reference to Fig. 1 to Fig. 7. Here, Fig. 1 is a diagram showing an example of a hardware configuration of a design user terminal according to an embodiment, Fig. 2 is a diagram showing an example of a functional configuration of the design user terminal, and Figs. 3 to 7 are diagrams showing examples of displays on a display screen of the design user terminal.

The design user terminal 10 is a user terminal used by the design engineer, and is a user terminal used by the design engineer to design and create a BIM design model, particularly for a building included in a system building.

Although not shown in the figure, other design user terminals include design user terminals used by structural designers, and design user terminals used by production designers who create BIM production models in which each component produced in a factory is reflected in the model. In addition, there are various other user terminals, such as cost estimation user terminals, construction planning user terminals, and actual construction user terminals (none of which are shown in the figure).

A design support system may be constructed in which such various design user terminals (user terminals) are connected to a shared server via a network, and BIM models (BIM design model, BIM structural model, BIM production model, etc.) created on each design user terminal are transmitted to and stored in the shared server each time, and user terminals that have been granted access rights can access the shared server. This design support system includes a form having a closed network in which information is shared only within a company such as a single house manufacturer, as well as a form having an open network that allows information sharing with external organizations (such as material and equipment suppliers owned by material and equipment suppliers who work together at the production design, facility design, construction planning, etc. stages). In addition to storing data, the shared server may also be a cloud server that allows multiple users to share various application software.

The design user terminal 10 according to the embodiment is a user terminal used by a design engineer as a design user terminal during the planning stage of a building included in a system building, and is used to design and create a BIM design model. During the planning stage, by viewing image data (BIM design model) of a three-dimensionally modeled building, the exterior and layout design of the building can be directly imagined.

Here, buildings included in system architecture include logistics warehouses, retail stores such as drugstores and convenience stores, etc.

As shown in FIG. 1, the design user terminal 10 is an information processing device such as a personal computer (PC), a workstation (WS), or a tablet, all of which are composed of a computer.

The computer constituting the design user terminal 10 includes a CPU (Central Processing Unit) 11, a main memory device 12, an auxiliary memory device 13, a communication IF (interface) 14, and an input/output IF 15, which are interconnected by a connection bus 16. The main memory device 12 and the auxiliary memory device 13 are computer-readable recording media. Note that each of the above components may be provided separately, or some of the components may not be provided.

The CPU 11 is also called an MPU (Microprocessor) or a processor, and may be a single processor or a multiprocessor. The CPU 11 is a central processing unit that performs overall control of the design user terminal 10, which is a computer. The CPU 11 provides functions that meet a specific purpose, for example, by expanding a program stored in the auxiliary storage device 13 in an executable manner in the working area of the main storage device 12, and controlling peripheral devices through the execution of the program.

The main memory device 12 stores computer programs executed by the CPU 11 and data processed by the CPU 11. The main memory device 12 includes, for example, a flash memory, a RAM (Random Access Memory), and a ROM (Read Only Memory). The auxiliary memory device 13 stores various programs and various data on a recording medium in a readable and writable manner, and is also called an external memory device. The auxiliary memory device 13 stores, for example, an OS (Operating System), various programs, various tables, and the like. The OS includes, for example, a communication interface program that transfers data with external devices connected via the communication IF 14. The external devices include, for example, information processing devices such as personal computers (PCs), workstations (WSs), servers, and mobile terminals connected to a network, as well as external memory devices.

The auxiliary storage device 13 is used, for example, as a storage area that supports the main storage device 12, and stores computer programs executed by the CPU 11, data processed by the CPU 11, etc. The auxiliary storage device 13 is a silicon disk including a non-volatile semiconductor memory (flash memory, EPROM (Erasable Programmable ROM)), a hard disk drive (HDD: Hard Disk Drive) device, a solid state drive device, etc. Examples of the auxiliary storage device 13 include drives for removable recording media such as CD drives, DVD drives, and BD drives. Examples of removable recording media include CDs, DVDs, BDs, USB (Universal Serial Bus) memories, and SD (Secure Digital) memory cards, etc.

The communication IF 14 is an interface with the network to which the design user terminal 10 and the like are connected. The communication IF 14 is connected to a shared server via the network, and downloads various application software used in designing the design, and receives as reference BIM design models created by other design engineers and stored on the shared server.

The input/output IF 15 is an interface that inputs and outputs data between devices connected to the design user terminal 10. Input devices such as a keyboard, a touch panel, a mouse, or other pointing device, and a microphone are connected to the input/output IF 15. The design user terminal 10 accepts operation instructions, etc. from an operator who operates the input device via the input/output IF 15.

The input/output IF 15 is also connected to display devices such as a liquid crystal display (LCD) panel or an organic electroluminescence (EL) panel, and output devices such as a printer and a speaker. The design user terminal 10 outputs data and information processed by the CPU 11 and data and information stored in the main memory device 12 and the auxiliary memory device 13 via the input/output IF 15.

2, the design user terminal 10 provides various functions, such as at least an acquisition unit 21, a selection request unit 23, a drawing unit 25, a display unit 27, and a storage unit 29, by executing a program by a CPU 11. At least some of the above processing functions may be provided by a DSP (Digital Signal Processor), a GPU (Graphics Processing Unit), etc. Similarly, at least some of the above processing functions may be provided by a dedicated LSI (large scale integration) such as an FPGA (Field-Programmable Gate Array), a numerical calculation processor, an image processing processor, or other digital circuits, etc.

The acquisition unit 21 acquires input data from the design engineer and stores (stores) it in the memory unit 29, and also receives application software stored in the shared server and reference BIM design models created by other design engineers. Furthermore, the acquisition unit 21 transmits the BIM design models created by the design engineers to the shared server.

Autodesk Revit (registered trademark) (manufactured by Autodesk) is installed or downloaded into the memory unit 29 as BIM software, and is set to be launched when designing the building.

The memory unit 29 also stores structure and use data related to multiple types of structures and uses, including the building's structural framework and uses, exterior material data related to one or more exterior materials specific to each structure and use, and folded plate data related to, for example, one type of folded plate that forms a folded plate roof.

The display unit 27 displays, on a display screen such as an LCD display, a number of add-in tools used to create a BIM design model, as shown in FIG. 3. In designing the design of a building included in a system architecture, the user presses "System Wizard 31" in the add-in tools. This System Wizard 31 is a tool that automatically creates an exterior model (BIM design model) of a system architecture building.

When "System Wizard 31" is pressed, the selection request unit 23 is activated, and the first selection request screen as shown in FIG. 4 is displayed on the display screen 26. The first selection request screen has selection boxes for "Product 32," "Exterior material 33," and "Wall wall 34," and also has an input box for "Design conditions 35."

Product 32 refers to a product type that is set for each structure and use. For example, the structural frame type of a steel-framed structure includes a one-story building, a two-story building, a structure using single beams, a structure using truss beams, etc., as well as a logistics warehouse, a retail store, etc., as a use.

In Figure 4, "Frest," "Comfort," "Lead," and "Lead Free" are examples of product names developed and commercialized by Daiwa House Industry Co., Ltd.

The design engineer selects from the product 32 selection menu the product that is best suited to the structure and use of the system-built building to be designed.

Each product included in products 32 is set with a product-specific type of exterior material (standard exterior material manufacturer, product number, etc.). For example, in FIG. 4, when product: Lead-free single-material beam 150 is set, the selection menu for "Exterior material 33" presents three types of exterior materials specific to that product: ceramic siding, metal siding, and corrugated iron sheet.

For each exterior material included in exterior material 33, the user is further required to select whether or not to include a "wainscot 34." The designer selects, for example, ceramic siding from the selection menu for exterior material 33, and then selects "with wainscot" from the selection menu for wainscot 34.

After selecting whether or not to include the product 32, exterior materials 33, and waist walls 34, the user sets various conditions included in the design conditions 35. These design conditions include snowfall (general area, heavy snowfall area) and snowfall height, wind load (reference wind speed), regional coefficient for seismic force, building use and ground surface roughness classification, and whether or not to install solar panels.

By selecting or inputting information for each item requested in FIG. 4 and pressing "Next," the second selection request screen shown in FIG. 5 and FIG. 6 is displayed on the display screen 26.

The second selection request screen is a request screen that requests the input of building information data regarding the building, including the floor dimensions and height dimensions of the building.

The screen shown in Figure 5 is for inputting values for the building's height, and the screen shown in Figure 6 is for inputting values related to the building's planar dimensions.

As shown in Figure 5, the required information in the height direction includes the following items: height from design ground level to floor level of the 1st floor ("100" in the figure), ceiling height below the water level of the 1st floor ("3600" in the figure), height from the below-water level ceiling surface of the 1st floor to the top of the underwater beam ("750" in the figure), height from design ground level to the top of the underwater beam ("4450" in the figure), roof slope ("3/100" in the figure), distance from above water to below water ("24000" in the figure), height from design ground level to the top of the above-water beam ("5170" in the figure), height from the top of the above-water beam to the top of the parapet ("960" in the figure), maximum height ("6130" in the figure), etc. Note that the units of each value are mm.

Enter design values for each item. Note that some items will have data entered automatically based on other input information.

The planar shape of the selected product is rectangular. The display screen 26 shown in FIG. 6 includes a roof information selection box 41 for selecting roof information and a plan dimension box 42 for setting plan dimensions.

In the roof information selection box 41, you can select the slope direction of the folded-plate roof and whether or not there is a eaves and its position. In the plan dimension box 42, a rectangular plan view of the building outline including the slope direction of the roof is displayed.

In the plan dimension box 42, the distance from above water to below water in Figure 5 ("24,000" in the figure) is automatically read and the length of one side of the rectangle in plan view (length in the gradient direction) is set, and the plan dimension is set by inputting the length in the direction perpendicular to this ("30,000" in the figure).

The exterior panel frame is formed by attaching exterior materials to a steel-framed exterior wall frame, and the exterior wall is formed by attaching multiple exterior panel frames to multiple exterior columns that are erected at intervals.

By entering the exterior wall panel width ("2000" in the figure), the number of exterior wall panels on each side of the rectangle in plan view is automatically displayed as the number of spans ("12", "15" in the figure). Note that, for example, the exterior wall panel width of 2000 mm in the illustrated example corresponds to the span length of the exterior column, so the number of exterior wall panels is the number of spans as it is.

In the roof information selection box 41, the user is prompted to select either the seam fastening type or the lap bolt fastening type for the folded-plate roof. In the illustrated example, "Hazel 166" (product name of Yodogawa Steel Works, Ltd.: Yodolof 166 seam fastening using seams), which is a seam fastening type, is selected.

By selecting and inputting the required items shown in Figure 6 and pressing "Create," the drawing unit 25 (see Figure 2) is activated and a BIM design model is drawn based on the selected and input information.

Figure 7 shows an oblique view of a BIM design model 50 for a retail store, as viewed from the front entrance, drawn by the drawing unit 25 and displayed on the display screen 26.

The BIM design model 50 has a set number of exterior wall panels 51 and spandrel walls 53, and a corrugated roof 55 with a set slope and slope direction.

On the display screen 26, a three-dimensional BIM design model 50 viewed from various directions can be displayed, and longitudinal and transverse cross-sectional views (two-dimensional BIM design model 50) cut at various positions can be displayed.

According to the illustrated design user terminal 10, structure/use data and exterior material data specific to each structure/use are stored in the memory unit 29, the selection request unit 23 requests the selection of structure/use and exterior material, and further requests the input of building information data such as the building's plan dimensions, and the drawing unit 25 draws a BIM design model 50 based on the input building information data, thereby eliminating the need to manually input information about objects and enabling efficient BIM design.

In particular, since the building to be designed is a system-built building in which some or all of the connections between components are standardized, information on the structure and use, which are representative examples of connections specific to standardized system-built buildings, and the exterior materials specific to that structure and use are stored in advance in the memory unit 29, and modeling is possible simply by selecting them, making this a suitable terminal for creating BIM design models for system-built buildings.

Note that the configurations described in the above embodiments may be combined with other components, 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 determined appropriately according to the application form.
