The logistics information database DB3 is a database in which information related to logistics such as inventory, accounting, and production planning is recorded.

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

<Device hardware configuration>
Next, the configuration of the design support device 1 used in the design support system will be explained. FIG. 2 is a block diagram conceptually showing a configuration example of the design support apparatus 1 described in the present application. The design support apparatus 1 includes various components such as a control section 10, a recording section 11, a storage section 12, an input section 13, a display section 14, and a communication section 15.

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

The recording unit 11 is a circuit configured using a hard disk, RAID (Redundant Arrays of Inexpensive Disks), nonvolatile memory such as flash memory, and volatile memory such as various RAMs (Random Access Memory), and stores various information. are recorded. The recording unit 11 records programs such as a basic program (OS: Operating System) and application programs (application programs) that operate on the basic program. As application programs, various programs such as a CAD program 110 for realizing a CAD system and a design support program 111 for realizing the design support apparatus 1 described in the present application are recorded.

Further, a part of the recording area of the recording unit 11 is used as various databases such as a CAD information database 112, a structure information database 113, and a logistics information database 114. The recorded contents of various databases such as the CAD information database 112, the structure information database 113, and the logistics information database 114 are local databases that are substantially the same as the databases with the same names connected to the communication network NW, or that are partially extracted from them. It is.

For example, similar to the structural information database DB2 connected to the communication network NW via the core device 2, the structural information database 113 contains standards, formulas, settings, etc. for performing structural calculations based on CAD data. Various data are recorded.

FIG. 3 is an explanatory diagram conceptually showing an example of recorded contents of the structure information database 113 included in the design support apparatus 1 described in the present application. FIG. 3 shows, as one of the setting items recorded in the structural information database 113, whether or not horizontal braces can be placed based on the length of the side for a beam section surrounded by horizontal structural members of a building. This shows an example of a table used for determination. In the table illustrated in Figure 3, the numerical values shown as the item names listed vertically and horizontally indicate the length of the side of the beam section in meters (m), and the "○" and "x" in each cell The symbol indicates whether horizontal braces can be placed. For example, it is possible to place horizontal braces on a beam section whose length and width are 0.75 m x 1.0 m, and for a beam section whose length and width are 0.5 m x 0.5 m, horizontal braces can be placed. Placement is not possible. In this application, a section surrounded by horizontal structural members of a building, for example, structural members such as beams hung substantially horizontally, is defined as a beam section, and the following explanation will be given.

FIG. 4 is an explanatory diagram conceptually showing an example of recorded contents of the structure information database 113 included in the design support apparatus 1 described in the present application. FIG. 4 exemplifies a table used to set the division length when dividing a beam section in the direction of the main reinforcement, as one of the setting items recorded in the structural information database 113. The lengths in the main reinforcement direction when dividing into sections α and β are shown in association with each other. Here, the term "main reinforcement direction" is used to generically refer to the direction in which the floor load is applied. For example, for a floor formed of a deck slab with reinforcing bars, it goes without saying that the direction of the main reinforcing bars is defined as the main reinforcing direction. In the case of floors using , the longitudinal direction of the slab is defined as the main reinforcing direction. In FIG. 4, the length of the section before division is recorded as data in the item "Original section length (m)", and the lengths of section α and section β after division are "section α (m)". and is recorded as data in the item “section β(m)”. For example, if the length of the beam section in the main reinforcement direction before division is 1.75 m, it is divided into a section α of 0.75 m and a section β of 1.0 m. Details of the process of dividing beam sections will be described later.

Returning to the block diagram of FIG. 2, the storage unit 12 is a circuit configured using volatile memory, and temporarily stores data generated when various programs are executed. Note that, for convenience, the recording section 11 and the storage section 12 are shown as different circuits, but they may be configured as one circuit, or they may complement each other in their functions.

The input unit 13 is a device such as a keyboard, mouse, touch panel, or digitizer. The display unit 14 is a device such as a liquid crystal display. Note that the input unit 13 and the display unit 14 may be provided as, for example, a liquid crystal touch panel in which a thin plate-like liquid crystal display and a touch panel are laminated.

The communication unit 15 is a device such as a LAN adapter, an antenna, and a control circuit, and is connected to the communication network NW through wired or wireless communication, and communicates with various devices including various databases.

The computer having the various configurations exemplified above reads various programs such as the CAD program 110 and the design support program 111 recorded in the recording unit 11 under the control of the control unit 10, and stores various information in the storage unit 12 as appropriate. By storing the information and executing various procedures, it operates as the design support device 1.

Regarding access to various databases, the control unit 10 and the communication unit 15 may be used as access means to access various databases connected via the communication network NW, and the control unit 10 may be used as an access means to access the various databases connected via the communication network NW. Various local databases recorded in the section 11 may be accessed. Hereinafter, modes of accessing various local databases recorded in the recording unit 11 will be explained as examples.

<Device software processing>
Next, processing of the design support device 1 used in the design support system will be explained. FIG. 5 is a flowchart illustrating an example of automatic beam placement processing of the design support apparatus 1 described in the present application. The automatic beam placement process is a process of automatically placing beams and reinforcing materials in accordance with changes in the positions of holes opened in the building during the design of the building using the CAD system. A hole opened in a building is a hole opened in a beam section, for example, for installing plumbing for water in units such as kitchens, toilets, bathrooms, washrooms, etc. vertically through the floor. It shows the holes such as through holes that are necessary when doing so. In other words, a change in the position of a hole that triggers automatic beam placement processing refers to a change in the position of a hole that is a trigger for automatic beam placement processing, when a unit such as a toilet is newly installed, the installation position is changed, or it is removed during the design of a building using a CAD system. This is a process of adding, changing, or deleting holes related to the unit. When changing the position of the hole, it is necessary to rearrange the beams and reinforcing materials in order to maintain the structural strength required for the building.

The control unit 10 included in the design support device 1 executes automatic beam placement processing by executing various programs such as a CAD program 110 and a design support program 111. The control unit 10 included in the design support device 1 executes CAD processing (S101). The CAD processing in step S101 indicates design support processing by a CAD system. In CAD processing, the CAD information database 112 is accessed, CAD data such as CAD data recorded in association with the client ID and CAD data that is a pre-recorded basic plan is extracted, and content is added and added as appropriate. This is done by making modifications.

FIG. 6 is an explanatory diagram showing an example of an image displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 6 shows an example of an image displayed during the CAD processing in step S101, in which a drawing of a building based on CAD data is displayed in the central drawing display area. In the drawing display area illustrated in FIG. 6, as a drawing of a building having a plurality of beam sections, a blueprint showing the arrangement of beam sections with respect to the floor of a specified floor is displayed. A building shown as a blueprint shows a plurality of beam sections, and each beam section shows the configuration of beams, braces serving as reinforcing materials, main reinforcement directions, and the like. Further, above the drawing display area, menu icons for executing various commands are displayed. On the left side of the drawing display area, there are shown areas such as an area where instructions being executed can be displayed, and an area where the hierarchy and type of the drawing displayed in the drawing display area can be displayed. A user who creates a drawing of a building using the design support device 1 operates the input unit 13 to select a target beam section, and selects a hole indicating the position of a hole to be opened in the selected beam section. Make an input to specify a change in position. Input to designate a change in hole position is performed as an operation such as designating a newly opened hole position, designating a changed hole position for an already opened hole, or erasing an already opened hole.

Returning to the flowchart of FIG. 5, the control unit 10 of the design support apparatus 1 receives an input from the input unit 13 specifying a change in the hole position within the selected beam section (S102). The control unit 10 reads the hole position in the specified beam section (S103), and further accesses the structural information database 113 to read the placement conditions of the beam and reinforcing material (S104).

Then, the control unit 10 of the design support device 1 performs the following operations based on various conditions such as the read hole position in the beam section, the interval in the direction perpendicular to the main reinforcement direction in the beam section, and the arrangement conditions of the beam and reinforcing material. The necessary placement positions of beams and reinforcing materials within the beam section are derived (S105). In step S105, based on the read beam section and the placement conditions of the beam and reinforcing material, it is determined whether or not to add a beam when a hole is opened in the beam section. For example, if the added hole is opened in a beam section whose size is larger than a size preset as an arrangement condition, it is determined that the beam needs to be added. Furthermore, when it is determined that a beam needs to be added, the placement position of the beam is derived. The arrangement positions of the beams are derived, for example, based on the arrangement conditions described in the table illustrated in FIG. 4. Once the placement position of the beam is derived, the placement position of the reinforcing material is derived so as to form a diagonal line within a section divided by the placed beam. Note that this example uses a horizontal brace as a reinforcing material, so the placement position of the reinforcing material is derived so that it forms a diagonal line within the section, but depending on the reinforcing material, the placement position may be determined based on other conditions. The placement position of the reinforcing material will be derived.

The control unit 10 that has derived the arrangement positions of the beam and the reinforcing material determines whether or not the beam and the reinforcing material can be arranged at the derived arrangement positions (S106). The determination in step S106 is made based on whether a prohibition condition recorded in the structure information database 113 is met. For example, whether or not the reinforcing material can be placed is determined by comparing it with prohibitive conditions listed in the table illustrated in FIG. 3 . For example, based on the table illustrated in FIG. 3, it is determined that horizontal braces can be placed in a beam section whose dimensions are 0.75 m x 1.0 m, and the horizontal braces are 0.5 m x 0. It is determined that placement of horizontal braces is not possible for a beam section that is 5 m.

If it is determined in step S106 that the beams and reinforcing materials can be placed at the derived placement positions (S106: YES), the control unit 10 deletes unnecessary beams and reinforcing materials (S107), and places the beams at the derived placement positions. is placed (S108), and the reinforcing material is placed at the derived placement position (S109). Deletion of unnecessary beams and reinforcing materials in step S107 is performed when already set beams and reinforcing materials are unnecessary or need to be moved to other placement positions due to changing or erasing hole positions. After performing the erasing process in step S107 as necessary, drawing is performed in steps S108 and S109 to arrange the beams and reinforcing materials at the derived placement positions. After executing the processing in steps S107 to S109, the control unit 10 returns to the CAD processing.

In step S106, if it is determined that the beam and the reinforcing material cannot be placed at the derived placement position (S106: NO), the control unit 10 generates an error message indicating that opening a hole at the specified hole position is not possible. A message is displayed on the display unit 14 (S110) to request re-designation of the hole position as appropriate, and the process returns to the CAD process.

The automatic beam placement process described using the flowchart in FIG. 5 will be described using an example of an image displayed on the display unit 14. 7 to 9 are explanatory diagrams showing examples of images displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 7 shows beam sections selected for specifying hole positions from the floor plan illustrated in FIG. 6. In the selected beam section horizontal braces are placed as reinforcement. Note that the double-headed arrow within the beam section indicates the direction of the main reinforcement. FIG. 8 shows a state in which the hole position has been designated from the state illustrated in FIG. A cross symbol is displayed in the circle indicating the hole position in the beam section. FIG. 9 shows a state in which the placement positions of beams and reinforcing materials are derived from the state illustrated in FIG. 8 based on the designation of hole positions, and the beams and reinforcing materials are placed at the derived placement positions. ing. As illustrated in FIGS. 7 to 9, by newly specifying a hole position within a beam section, the selected beam section is divided by adding a new beam, and reinforcing material is added to each divided section. is placed. A new beam is added in a direction perpendicular to the main reinforcement direction. Note that if a designation is made to delete the hole position from the state illustrated in FIG. 9, unnecessary beams and reinforcing materials are deleted, resulting in the state illustrated in FIG. 7.

10 to 12 are explanatory diagrams showing examples of images displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIGS. 10 to 12 show the relationship between the hole positions specified within the beam section and the arrangement positions of the beams and reinforcing materials derived as the hole positions are specified. FIG. 10 is an image of a beam section displayed on the display unit 14 included in the design support apparatus 1 described in the present application, and illustrates a beam section whose length in the main reinforcement direction is 1.75 m. Within the beam section illustrated in FIG. 10, based on the beam placement conditions such as the setting items illustrated in FIG. The location of the reinforcement is determined. Based on the settings illustrated in Figure 4, in the beam section illustrated in Figure 10, the position will be different depending on whether area A on the right side of the center is specified or area B on the left side of the center. Beams and reinforcements are placed.

FIG. 11 illustrates the beam and reinforcing material that are placed when the hole position is specified within the area A within the beam section. Based on the setting items illustrated in Fig. 4, if the length of the section before division in the main reinforcement direction is 1.75 m, the beams are placed at the positions where they are divided into 0.75 m and 1.0 m as section α and section β. is placed. Therefore, for the specified hole position in area A on the right, the length of the left section in the main reinforcement direction is 0.75 m, and the length of the right section in the main reinforcement direction is 1.0 m. The beams are arranged so that the longitudinal direction is perpendicular to the direction, and the beam section is divided into a left section α and a right section β by the arranged beams. In addition, horizontal braces are placed as reinforcing members at diagonal positions within the partitions on both sides.

FIG. 12 illustrates the beams and reinforcing materials that are placed when the hole position is specified within region B within the beam section. For specifying the hole position in area B on the left, based on the settings illustrated in Figure 4, the length in the main reinforcement direction of the left section is 1.0 m, and the length in the main reinforcement direction of the right section is 1.0 m. A beam is placed at a position of 0.75 m so that its longitudinal direction is perpendicular to the direction of the main reinforcement, and the placed beam divides the beam section into a left section β and a right section α. In addition, horizontal braces are placed as reinforcing members at diagonal positions within the partitions on both sides.

13 to 15 are explanatory diagrams showing examples of images displayed on the display unit 14 included in the design support apparatus 1 described in the present application. FIGS. 13 to 15 show the relationship between the hole positions specified within the beam section and the arrangement positions of the beams and reinforcing materials derived as the hole positions are specified. FIG. 13 shows an image of a beam section displayed on the display unit 14 included in the design support apparatus 1 described in the present application. Within the beam section illustrated in FIG. 13, based on the beam placement conditions preset in the structural information database 113, the placement position of the beam and furthermore the placement position of the reinforcing material are determined from the specified hole position. . Figures 13 to 15 show cases in which an area C up to 0.75 m from the left and right ends is specified in a beam section with a length of 2.0 m in the main reinforcement direction (horizontal direction in the figure), and a case where the main reinforcement near the center is specified. An example is shown in which beams and reinforcing materials are arranged at different positions depending on the case where a region D with a width in the direction of 0.5 m is specified.

FIG. 14 illustrates the beam and reinforcing material that are placed when the hole position is specified within the region C within the beam section. As illustrated in FIG. 14, when a hole position is specified in area C, a beam is placed in the center of the beam section with the longitudinal direction perpendicular to the main reinforcement direction, and the placed beam , the width of each section on both sides is 1.0 m. In addition, horizontal braces are placed as reinforcing members at diagonal positions within the partitions on both sides.

FIG. 15 illustrates the beam and reinforcing material that are placed when the hole position is specified within the region D within the beam section. As illustrated in Fig. 15, when the hole position is specified in area D, the hole position is set at a position 0.5 m from the left and right ends of the beam section, respectively, so that the direction perpendicular to the main reinforcement direction is the longitudinal direction. The beams are arranged, and the inside of the beam section is divided into three sections by the two arranged beams. In addition, horizontal braces are arranged as reinforcing members at diagonal positions within each of the divided sections.

As described above, the design support device 1 described in the present application erases existing beams and reinforcing materials, changes hole positions, and moves beams and reinforcements to new positions by simply specifying changes in hole positions within a beam section. A series of operations such as rearranging materials can be performed automatically. The automatic beam placement process performed by such a design support device 1 is based on preset settings, prohibitions, etc., and therefore the beams are placed at positions that satisfy the structural design conditions.

In this way, automatic beam placement processing is executed.

In the automatic beam placement process described above, beams are automatically placed, but beams can also be placed by the user's operations. FIG. 16 is a flowchart illustrating an example of manual beam placement processing of the design support apparatus 1 described in the present application. The manual beam placement process is a process in which beams are placed by a user's operation during the design of a building using a CAD system.

The control unit 10 included in the design support device 1 executes manual beam placement processing by running various programs such as a CAD program 110 and a design support program 111. The control unit 10 included in the design support device 1 executes CAD processing (S201). A user who creates a drawing of a building using the design support device 1 operates the input unit 13 to select a target beam section, and inputs input to specify a beam to be additionally placed in the selected beam section. I do. Beam specification is performed as an operation of specifying a rectangular area that includes a newly added beam.

The control unit 10 receives an input from the input unit 13 of a command to add a beam within the selected beam section (S202), and receives an input specifying a rectangular area including the beam to be added (S203).

17 and 18 are explanatory diagrams showing examples of images displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 17 is an image of a beam section displayed on the display unit 14 included in the design support device 1 described in the present application, in which a beam section is selected from the blueprint and an instruction to add a beam is input in step S202. It shows. FIG. 18 shows a state in which a rectangular area is specified from the state shown in FIG. 17, and the specified rectangular area is indicated by diagonal lines. To specify the rectangular area, various methods are applied, such as specifying horizontal and vertical directions by dragging the mouse, which is the input section 13, specifying diagonal lines, and specifying coordinates by inputting from the keyboard, which is the input section 13. It is possible to do so. If the specified rectangular area is specified to pass two other beams, the beam is placed along the specified rectangular area at a position where it passes the other two beams. The placed beam circumscribes two sides of the rectangular area. If one of the two sides passing the beam forming the designated rectangular area overlaps another beam, the beam is placed only at a position circumscribing the non-overlapping side.

Returning to the flowchart of FIG. 16, the control unit 10 that has received the designation of the rectangular area determines whether the beam position based on the designated rectangular area is appropriate (S204).

If it is determined in step S204 that the beam position based on the specified rectangular area is appropriate (S204: YES), the control unit 10 moves the specified beam to a position circumscribing the side along the side of the rectangular area to which the specified beam is to be passed. A beam is placed at (S205).

FIG. 19 is an explanatory diagram showing an example of an image displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 19 is an image of a beam section displayed on the display unit 14 included in the design support apparatus 1 described in the present application, and shows a state in which the beams are arranged within the rectangular area specified in step S205. As shown in FIG. 19, when the beam position in the specified rectangular area is appropriate, a beam of a predetermined width is placed along the specified rectangular area at a position where it passes two other beams. The placed beams circumscribe two sides of the rectangular area. Note that it is also possible to specify the beam width and beam thickness (thickness of the iron material).

Returning to the flowchart of FIG. 16, if it is determined in step S204 that the beam position based on the specified rectangular area is not appropriate (S204: NO), the control unit 10 determines that the specified rectangular area is not appropriate. An error message indicating this is displayed on the display unit 14 (S206), a request is made to re-specify the beam position as appropriate, and the process returns to the CAD process.

FIG. 20 is an explanatory diagram showing an example of an image displayed on the display section 14 included in the design support apparatus 1 described in the present application. FIG. 20 is an image of a beam section displayed on the display unit 14 included in the design support apparatus 1 described in the present application, and shows an example of a rectangular area that is determined to be inappropriate. The rectangular area illustrated in FIG. 20 spans only one beam, and it is determined that it is inappropriate to add a beam at this position.

In this way, manual beam placement processing is executed.
