It is done by making changes.

The control unit 10 reads the information indicating the outline of the building under design from the CAD data during the CAD processing (step S2). Step S2 is a process of reading an outline in the horizontal direction with respect to the floor of the building to be processed. The outline read in step S2 includes not only the outer wall which is the outer edge of the building but also the wall of the building facing the courtyard which is formed as an external space in the site. That is, the outline of the building is a wall that separates the inside of the building for each floor from the outside or the courtyard.

FIG. 4 is a schematic diagram conceptually showing an example of processing by the design support device 1 described in the present application.

Shown. Inside the building, the square shown in the upper right part indicates the courtyard of the building. The numerical value of "500" in FIG. 4 indicates the length in millimeters, and is a scale indicating the size of the building based on the predetermined length.

Returning to the flowchart of FIG. 3, the control unit 10 scans the inside of the building formed by the read outline in the first horizontal direction, and extracts the section inside the building sandwiched between the outlines ( Step S3).

FIG. 5 is a schematic diagram conceptually showing an example of processing by the design support device 1 described in the present application. FIG. 5 conceptually shows a state in which the design support device 1 scans in the first horizontal direction and extracts a section inside the building in step S3. In FIG. 5, the first horizontal direction is the X-axis direction (horizontal direction), and in step S3, the process of scanning the inside of the building in the X-axis direction is performed at intervals of 1/2 predetermined length. In the embodiment illustrated in the present application, since the predetermined length is set to 500 mm, the scanning interval is set to 250 mm, and in FIG. 5, the scanning lines at 250 mm intervals are shown by thick lines. The section sandwiched between the outlines indicates a line segment between opposing walls on one scanning line. Since the section extracted as a line segment is limited to the section inside the building, the section is not extracted from the courtyard.

Returning to the flowchart of FIG. 3, the control unit 10 scans the inside of the building formed by the read outline in the second horizontal direction orthogonal to the first horizontal direction, and the building sandwiched between the outlines. The internal section is extracted (step S4).

In FIG. 6, the second horizontal direction is the Y-axis direction (vertical direction) orthogonal to the X-axis direction, and in step S4, the process of scanning the inside of the building in the Y-axis direction is performed at intervals of 1/2 predetermined length. Do it with. In the embodiment illustrated in the present application, the scanning interval is set to 250 mm, and in FIG. 6, scanning lines at intervals of 250 mm are shown by thick lines. That is, step S4 is a process of performing the same process as step S3 in the Y-axis direction.

Returning to the flowchart of FIG. 3, the control unit 10 reads information indicating the type and arrangement position of the rigid frame columns arranged on the floor of the building to be processed and the length of the horizontal cross section in the longitudinal direction from the CAD data ( Step S5). In step S5, information such as the type of rigid frame pillar and the arrangement position is read from the CAD data. Further, in step S5, since the length of the horizontal cross section in the longitudinal direction is a predetermined length, it may be read from the standard of the member recorded in the structural information database 113.

FIG. 7 is a schematic diagram conceptually showing an example of processing by the design support device 1 described in the present application. FIG. 7 conceptually shows a state in which the ramen pillars read in step S5 are arranged on the outline of the building read in step S2. As described above, the rigid frame column exemplified as the embodiment of the present application is a WH section steel rigid frame column, and in FIG. 7, symbols imitating the cross section of the WH section steel rigid frame column shown as A, B, C, ..., G are used. , Shows the arrangement of rigid frame pillars. As described above, the predetermined length in the embodiment of the present application is set based on the length in the longitudinal direction of the horizontal cross section of the rigid frame column to be arranged, and is 500 mm.

Returning to the flowchart of FIG. 3, the control unit 10 detects the arrangement of the WH-shaped steel rigid frame columns corresponding to the prohibited items arranged at the arrangement positions that should not be arranged among the arranged WH-shaped steel rigid frame columns. (Step S6). The forbidden matter that is the condition to be detected in step S6 is the arrangement of the WH-shaped steel ramen columns that connect the opposing outlines in the longitudinal direction with respect to the section where the intervals between the opposing outlines of the building are predetermined lengths. That is, the length of the section extracted by scanning in steps S3 and S4 substantially matches the length in the longitudinal direction of the WH-shaped steel rigid frame column, which is a predetermined length, and the section is in the longitudinal direction along the scanning direction. When the WH-shaped steel ramen columns are arranged so as to be connected by, the arrangement of the ramen columns is detected as a prohibited matter. In other words, if the WH-shaped steel rigid frame columns are arranged so as to connect the opposing walls in the longitudinal direction and are blocked by the WH-shaped steel rigid frame columns, the prohibition applies. For example, in the schematic diagram illustrated in FIG. 7, among the WH-shaped steel rigid frame columns, the arrangement of the rigid frame columns shown by A, B, E and F corresponds to the prohibited matter detected in step S6.

Among the WH-shaped steel rigid frame columns detected as prohibited items in step S6, the control unit 10 is arranged so that the outline of the building extends in the direction extending from the tip position in the longitudinal direction.

For example, in the schematic diagram illustrated in FIG. 7, among the WH-shaped steel rigid frame columns detected as falling under the prohibited items in step S6, the arrangement of the WH-shaped steel rigid frame columns shown in B and F is prohibited. Exclude from the target of detection as.

The control unit 10 executes kinsoku processing for the arrangement of the WH-shaped steel rigid frame columns detected as falling under the prohibited items in steps S6 and S7 (step S8). The prohibition processing in step S8 includes a process of automatically deleting the WH-shaped steel rigid frame columns detected as prohibited items, a process of displaying an explanation indicating that the detected WH-shaped steel rigid frame columns are prohibited items, and a CAD process.
