Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a CAD system for a building for designing a building such as a panel-type building provided with a load-bearing wall for supporting a building load by a computer.

[0002]

2. Description of the Related Art Conventionally, a panel-type building constructed by combining a plurality of panels manufactured in a factory at a construction site has been used. Buildings that make up panel-type buildings are floor panels,
It is built by combining various types of panels such as outer wall panels, inner wall panels, roof panels, etc., but the outer wall composed of outer wall panels and some inner walls composed of inner wall panels are load-bearing walls that support building loads. Is done.

[0003] In this panel-type building, products (panel-type buildings) to be provided to customers are already manufactured, whereby the types of products to be designed and manufactured are limited, and design and manufacturing operations are made more efficient. However, in this case, it is difficult to sufficiently respond to various requests from customers. Therefore, like a general custom-built building, when designing buildings one by one according to customer requirements, a CAD system that supports the design work is used so that the efficiency of the design work is sufficiently ensured. .

In the CAD system, a layout plan for designing a design plan such as a layout of a building and a design system for individual building components are separately provided. In the CAD for floor plan design, basically, while inputting each part such as a partition wall, a stair, an elevator, a door, a system kitchen, a bath, and a toilet arranged on each floor of the building on a plan view of the building. The floor plan is being designed.

[0005] In the CAD for designing components, the size, allocation, and the like of building components such as an outer wall panel, an inner wall panel, a floor panel, and a roof panel are set. For example, the work of setting a wall line such as a load-bearing wall line or a support wall line on a load-bearing wall, setting a roof beam supporting a roof panel, or setting an area and a laying direction of a floor panel is, This CAD
Done in Normally, after designing the floor plan of a building, wall lines of the outer wall panel and the inner wall panel are set.

[0006]

In the conventional CAD system, the layout plan of the building and the setting of the wall line of the outer wall panel and the inner wall panel are performed by separate CAD systems. Each of these CAD systems is provided with a setting (editing) screen, and a layout plan and a wall line setting are performed on different screens. In CAD for floor plan design, customers judge good or bad usability while looking at the plan view,
The plan view is often changed.

[0007] Therefore, in designing a building, it is necessary to operate the CAD for designing components after performing setting work using the CAD for floor plan. If there is a change in the floor plan of the building, it is necessary to operate the setting screen of the CAD for floor plan design, and then operate the setting screen of a different CAD to correct the wall line setting. Furthermore, if the wall layout cannot be set in the changed floor plan, the floor plan CAD must be operated again to change the floor plan. Therefore, conventionally, a plurality of CAD systems have to be operated in accordance with a change in the floor plan, and there is a problem that the design work becomes complicated.

[0008] An object of the present invention is to provide a CAD system for a building that can efficiently design a building even if the floor plan of the building is changed.

[0009]

SUMMARY OF THE INVENTION Accordingly, the present invention aims at achieving the above object by setting a wall line on a load-bearing wall and setting a plane (plan) of a building on the same screen. is there. Specifically, the CAD system 1 for a building according to the present invention will be described with reference to the drawings. The CAD system 1 for a building for designing a building provided with a load-bearing wall for supporting a building load is described below.
The AD system 1 is a plan view designing means 31 for arranging the parts on a plane of the building and designing a plan view of the building using part data relating to the parts arranged in the building.
And the wall lines P1, P on the load-bearing walls of the walls 41, 42 of the building.
And a wall line setting means 32 for setting 2 and setting the wall lines P1 and P2 of the wall line setting means 32 and the plan view of the building by the plan view design means 31 on the same screen 2. I do. In the above configuration, in the present invention, the wall line set by the wall line setting means 32 is a load-bearing wall line P1 indicating a wall supporting both vertical and horizontal loads of the building, and a vertical line of the building. Support wall line P2 indicating the wall supporting the load in the direction
And

According to the present invention having such a configuration, the plan view design means 31 sets the building plane (floor layout) based on the part data of the building, and then the wall line setting means 32 supports the building load. Set the wall lines P1 and P2 on the bearing wall. When the floor plan of the building is changed by the plan view design means 31,
The wall line is reset by the wall line setting means 32 based on the changed floor plan. In the present invention, the building plane and wall line P
Since the setting work of P1 and P2 can be performed on the same screen 2, the building can be designed more efficiently than the conventional example in which different screens are operated.

Here, in the present invention, the wall line setting means 3
2 may be configured to determine whether the load-bearing wall line P1 forms a prescribed load-bearing wall, and display the result of the determination.
When the result (NG) indicating that the prescribed bearing wall is not formed is displayed, the bearing wall line P1 or the plan view of the building is changed.
In this configuration, by displaying whether or not the load-bearing wall line P1 forms the prescribed load-bearing wall, it is possible to quickly respond in a later process, and the building can be designed more efficiently. .

Further, the CAD system for buildings of the present invention comprises:
A roof beam setting unit for setting a roof beam after the wall line setting unit determines that the load-bearing wall line forms a specified load-bearing wall; A configuration in which the plan view of the building of the diagram design means 31 is set on the same screen 2 is also possible. In this configuration, since the roof beam Q of the roof beam setting means 33 and the plan view of the building of the plan view design means 31 are displayed on the same screen 2, the roof beam Q is checked while checking the floor plan of the building and the position of the wall line. Can be set. Therefore, compared with the conventional example in which different screens are operated, the setting of the roof beams, and the design of the building can be performed more efficiently. In performing the setting operation by the roof beam setting means 33, an operator visually checks a screen to determine whether or not both ends of the roof beam Q are above the wall lines P1 and P2. Is not on the wall lines P1 and P2, the wall lines P1 and P2 for receiving the roof beam Q are added.

The CAD system for a building according to the present invention comprises:
After the roof beam Q is set by the roof beam setting means 33, a floor panel setting means 34 for setting the area and the laying direction of the floor panel R is provided. The floor panel R of the floor panel setting means 34 and the plan view design means 31 are provided. The same screen 2 with the floor plan of the building
Alternatively, the setting may be made by setting. In this configuration, since the floor panel R of the floor panel setting means 34 and the plan view of the building by the plan view design means 31 are displayed on the same screen 2, the floor panel R is checked while checking the floor plan of the building and the position of the wall line. Can be set. For this reason, the setting of the floor panel R and the design of the building can be performed more efficiently than in the conventional example in which different screens are operated. When operating the floor panel setting means 34, an operator looks at the screen 2 and determines whether or not the end of the floor panel R is above the wall lines P1 and P2. If the section is not above the wall lines P1 and P2, the lower floor wall lines P1 and P2 that receive the floor panel R are added.
