[0003] By the way, the conventional system is,
Because the purpose was to calculate the total, it was not possible to generate an accurate rebar arrangement drawing. That is, since the integration is based on the vertical and horizontal grids, the structural elements (slabs, walls, beams,
If the shape of the pillar) is out of the center of the street, has a shape other than rectangular, or projects beyond the center of the street and projects into the air, replace it with an appropriate shape or structure, I do. Therefore, the rebar arrangement drawing generated by such a system lacks accuracy. Since the rebar arrangement drawing performs the rebar arrangement work based on it, it must match the details of the actual structure. Lack of accuracy can lead to rebar collisions or irrational reinforcement at the actual construction site. It is difficult to adopt the rebar arrangement drawing generated by the conventional integration system in an actual site, and as a result, it is necessary to manually create the rebar arrangement drawing independently of the rebar integration.

Next, the details of each part in FIG. 2 will be further described with reference to FIGS.

FIG. 3 shows the flow of the processing of the bar arrangement design support system. In FIG. 3, first, general specifications are registered (S40). The general specification registration is for appropriately registering the reinforcing arrangement specifications for each of the Architectural Institute of Japan, the general construction company, and the government. It is preferable to prepare a plurality of sets of reinforcing bar specifications for each of the general construction companies and government agencies based on the common specification of reinforcing bars of the Architectural Institute of Japan. When designing concrete reinforcement, take out the most appropriate reinforcement specification,
Modifications will be made as necessary. In this embodiment, a template for general specification registration is generated based on the Architectural Institute of Japan common arrangement specification, and in each stage of the registration items,
The specifications of each general construction company are registered so that they can be selected as options.

The general specification registration includes common item registration common to constituent elements and general specification registration for each type of constituent element. The general specification registration for each component type includes basic general specification registration, column general specification registration, beam general specification registration, slab general specification registration, wall general specification registration, and underground external wall general specification registration. FIG. 4 shows a state of setting the joint position registration specification in the common specification registration. FIG. 5 shows how to set a joint point in the common specification registration.

Now, it is assumed that the general specification registration (S40) has already been completed. When designing bar arrangements,
The construction outline is registered (S41). This registration is used for identification of the construction and the like, and the registration of the construction name, the name of the design office, the arrangement specifications to be used, and the like are performed. After this, step S
At 42, the used material type of the reinforcing bar is registered. The materials used are ordinary deformed bars and threaded bars. Next, floor height registration is performed (S43). In this step, the number of floors on the top floor, the number of basement floors, and the height of each floor are registered. After that, span registration is performed (S44).

The span registration (S44) includes common span registration (first component placement span), detailed span registration (second component placement span), and diagonal grid registration. The common span registration is for registering a span common to all floors. FIG. 6 shows a state of common span registration, in which 1, 2, 3, 4, 5, and 6 spans are registered in the vertical direction, and A, B, C, D, and E spans are registered in the horizontal direction. I have. By this registration work, a common span is set along the vertical and horizontal lines common to all floors. This allows
The span registration work for each floor can be reduced.

FIG. 7 shows how the detailed span is registered. The detailed spans 5A, 5B and 5C are registered based on the core 5 as the starting point. By this registration work, the position designation of the component on each floor that does not match the common span can be set in detail.

FIG. 8 shows the registration of diagonal streets. In this figure, in addition to the common spans of 1 to 6 and A to E, detailed spans based on the common spans (with suffixes), diagonal lines connecting intersections (1, D) and intersections (6, A). The grid is registered. The intersections need not be the ones between the common spans, and may be the intersections between the common spans and the detail spans or the intersections between the detail spans. By registering the diagonal grid, it is possible to deal with components positioned along the diagonal direction.

Next, a section list is registered in step S45. The section list registration is for registering the section shape of each component. The section list registration includes registration for each type of component, such as independent foundation section list registration, column section list registration, beam section list registration, and the like. FIG. 9 shows a state of registration of the independent basic section list. Each registered section is assigned a unique section symbol.

Next, position registration is performed in step S46. The position registration is for registering the position of each component in the plane direction and the vertical direction. For this registration, the cross section symbols (F1, F2, etc.) registered in step S45 are used. By this position registration, the positions of all the constituent elements of the building structure are set.

FIG. 10 shows the position registration of the independent foundation, and FIG. 11 shows the position registration of the pillar.

Even when the normal reinforcing rule cannot be applied, by setting a dummy (empty) column or beam that does not originally exist, the normal reinforcing rule can be applied to such a structure as it is. I have to. In this case, no reinforcement is provided on the dummy pillars or beams, so a flag indicating that it is a dummy should be set at the time of position registration. Components are not reflected. This flag can be registered by selecting normal / dummy, for example, as shown in FIG. 12 in the case of pillar position registration (see arrow).

Next, the registration of components such as the opening of the wall,
The registration of the connection between the components is performed (S47, S49), and the plan view and the elevation view of the skeleton are printed out (S49, S49).
50).

Thereafter, in step S51, automatic bar arrangement is performed based on the selected general specification, section list, and component position. By this automatic arrangement, arrangement according to general specifications is performed. Then, in step S52, the arrangement of the reinforcing bars is corrected while checking the actual arrangement of the reinforcing bars on the monitor. This reinforcement arrangement manually sets more rational arrangements. In step S53, the degree of arrangement of the reinforcing bars is confirmed and adjusted.

With the above, the bar arrangement design is completed. After this, the rebar arrangement drawing and the fit-in drawing are printed out (S54, S
55). Further, the used rebar materials are totaled, and an integrated form is output (S57).

As described above, in this embodiment, the registration can be saved by the common span registration. In addition, by adopting the detailed span registration and the diagonal grid registration, it is possible to perform the reinforcement arrangement design based on the actual shape of the constituent element, and it is possible to generate not only the integration but also the arrangement arrangement drawing. . In addition, even in situations where normal bar arrangement rules cannot be applied, the introduction of dummy components makes it possible to apply bar arrangement rules uniformly, and as a result, exceptionally manual integration and drawing can be minimized. it can. Furthermore, by registering a plurality of sets of general specifications, the number of registration operations for each construction can be reduced.
