[Background]
Conventionally, in order to increase the industrialization rate and shorten the construction period at the construction site, a panel method for constructing a building by combining a plurality of wood panels has been used.
In prefabricated buildings built by the panel method, the horizontal surface of the floor, roof, etc. is composed of floor panels, roof panels, etc., and the wall surface which is the vertical surface is composed of wall panels, small wall panels, etc. ing. At this time, in order to efficiently distribute the load, generally, the upper and lower floor wall panels are arranged at the same position in plan view via the upper floor panel.
[0003]
When building a building using the panel method, a building plan that reflects the customer's needs is created, and a structural plan is created based on the plan of the building based on this plan. In the structural plan, structural checks such as setting of the load-bearing wall line and calculation of the cross-section of the members are performed on the floor plan of each floor. The plan view thus completed is also used as a drawing for the customer to confirm the design items.
Then, based on this plan view, a floor plan of each part such as a wall, a floor, a ceiling, a roof, etc. is created and the panel is assigned.
[0004]
In such a design work, a CAD system for creating a plan view is used in order to increase the work efficiency of the structure plan based on the plan view.
This CAD system supports the work of designing a plan view based on a plan. According to this CAD system, a structural check can be performed quickly and accurately, and it can be easily performed even when a structural failure occurs. The advantage that the design can be changed is obtained.
[0005]
[Problems to be solved by the invention]
By the way, when a load-bearing wall line is set in the plan view of each floor, the position of the load-bearing wall line may differ between the upper and lower floors depending on the building plan. In this case, in order to ensure the structural strength as the load-bearing wall line, it is necessary to provide a reinforcing member such as a descending wall panel (small wall panel) or a beam immediately below the load-bearing wall line on the upper floor.
However, if the necessary cross section of the reinforcing member is calculated by calculating the cross section described above, the lower end of the reinforcing member may protrude from the ceiling surface of the lower floor determined in the plan.
Whether or not the reinforcing member protrudes is a matter that can be confirmed for the first time by comparing the plan view, the cross-sectional calculation result, and the plan, and therefore the judgment (confirmation) time tends to be delayed. In other words, if the judgment time is late, if the design change is made to fit the protruding reinforcing member within the ceiling surface, the change will affect other design items, and the efficiency of the design work will be reduced. there were.
[0006]
An object of the present invention is to provide a CAD system for creating a plan view that can quickly find a member protruding from a ceiling surface determined by a plan, thereby realizing high design efficiency.
