Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a CAD system for a unit building which supports a designing operation of a unit building using a computer.

[0002]

2. Description of the Related Art Conventionally, unit-type buildings constructed by combining a plurality of box-shaped building units manufactured in a factory at a building site have been used. As a building unit, a normal building unit having a normal floor height is known. As shown in FIG. 16, the normal building unit has four pillars 11 at the four corners.
It has a rectangular frame 14 whose upper and lower ends are connected by a ceiling beam 12 and a floor beam 13. The ceiling beam 12 includes a long side ceiling beam 12A and a short side ceiling beam 1A having different lengths.
2B are provided. As the floor beam 13, the ceiling beam 12
Similarly, a long side floor beam 13A and a short side floor beam 13B having different lengths are provided. To such a skeleton 14, work materials such as a ceiling surface material and a floor surface material (not shown), an outer wall material and a partition wall are attached.

According to such a unit-type building, when a building unit is manufactured at a factory, the work conventionally performed at the building site is almost entirely performed at the factory, and the work at the building site is significantly reduced. The advantage is that high quality buildings can be built in a short time. Therefore, the building as a product to be provided to the customer is made into a ready-made unit to be a unit-type building, thereby limiting the types of products to be designed and manufactured, and improving the efficiency of the design work and the manufacturing work. In this case, it may be difficult to sufficiently respond to various requests from customers.

[0004] Therefore, as in the case of a general custom-built building, unit-type buildings are designed one by one according to customer requirements, and in designing the design, the design work is performed so that the efficiency of the design work is sufficiently ensured. A CAD system to be supported is used (see Japanese Patent Application Laid-Open No. 8-137930). Such a C
In the AD system, in order to respond to various demands of customers, in designing the overall shape of the unit-type building, as shown in FIG. 17, in addition to the normal building unit 15 having the above-described normal floor height, the normal building unit 15 Special building units such as a tall building unit 16 having a higher floor height and trapezoidal building units 17 to 19 having an elevated trapezoidal shape can be used. Here, trapezoidal building unit 1
7 is a trapezoidal shape with one side chamfered, the trapezoidal building unit 18 is a trapezoidal shape with two opposing sides chamfered, and the trapezoidal building unit 19 is a trapezoidal shape with two adjacent sides chamfered. It has a trapezoidal shape. In this case, both a normal building unit and a special building unit are represented on the plan view of the unit building.

[0005]

However, the ordinary building unit and the special unit described above differ only in the elevation shape and have the same plane shape. Therefore, when designing the plan view of the unit type building, the operator is required. Since it is not possible to discriminate between the two, there is a risk of erroneous recognition or erroneous operation.In addition, it is necessary to design the plan with reference to other documents and drawings, such as a meeting with the customer. It took a lot of effort and time. In addition, when the name of a special building unit is displayed on the plan view in order to distinguish the special building unit from the normal building unit, it may be complicated with other characters or module lines, and the plan view may be difficult to see. .

By simply doing so, the selected building unit T1 is set as the special building unit D1 having the selected elevation shape (c) -2 of the trapezoidal building unit and is indicated by the symbol "DAI". Without complicating the characters and lines of
An operator can easily distinguish a special building unit from a normal building unit. Therefore, on top which can prevent false or incorrect operation of the operator, since there is no need to design a plan view other documents, with reference to the accompanying drawings, it is possible to easily design work.

(2) Since the folding positions and the descending directions of the ceiling surfaces of the special building units D1 to D4 having a trapezoidal elevation are generated on the plan view, for example, parts such as the partition walls 61 and 62 and the internal door 66 are formed. When designing the layout, the operator can easily form an image of the internal space in the special building units D1 to D4, so that the work efficiency of the design work can be improved.

Can be prevented, and the work efficiency of the design work can be improved.

(4) By selecting one of the unit module core wire G2 and the floor area core wire G4,
Since the dimension lines A1 and A2 for the selected one are generated, the dimension lines can be generated for the desired dimensions on the plan view, and the work efficiency of the floor area calculation work and the design work can be improved.

(5) By selecting only a part of the outer wall 63 and the partition walls 61 and 62 of the unit-type building designed on the plan view, the selected walls 61 to 6 can be selected when printing the plan view.
Since 3 is colored in a preset black color, it is not necessary to paint the wall after printing and identify the wall, thereby improving the design work efficiency.

It should be noted that the present invention is not limited to the above-described embodiment, but includes modifications and improvements as long as the object of the present invention can be achieved.

According to the CAD system for unit buildings of the present invention, the following effects can be obtained. According to the CAD system for a unit-type building according to claim 1, one of building units constituting the unit-type building is selected, and among the plurality of floor-height building units and trapezoidal building units, the elevation shape is selected. By simply selecting one of the above, the selected building unit is set as a special building unit having the selected elevation shape such as a tall building unit, a trapezoidal building unit, etc., and is indicated by a symbol. The operator can easily distinguish the special building unit from the normal building unit without complicating other characters and lines. Therefore, it is possible to prevent operator's misconception and erroneous operation,
Since there is no need to design a plan view with reference to other documents and drawings, design work can be easily performed.

The CAD for a unit building according to claim 2.
According to the system, since the bending position and the descending direction of the ceiling surface of the trapezoidal building unit were generated on the plan view,
For example, when designing the layout of parts such as partition walls and doors,
Since the operator can easily form an image of the internal space in the special building unit, the work efficiency of the design work can be improved.

A CAD for a unit building according to claim 3.
According to the system, when performing the work of designing the overall shape of the unit-type building, the work of designing the components in the building unit, and the work of calculating the floor area, the unit module core wire, the grid module core wire, and the floor area core are used. Since only a desired core wire among the lines can be displayed on the plan view, erroneous recognition of unnecessary lines on the plan view and erroneous operations such as mouse operation can be prevented, and work efficiency of design work can be improved. .

The CAD for a unit building according to claim 4.
According to the system, since the dimension line for the selected one is generated simply by selecting one of the unit module core line and the floor area core line, the dimension line for the desired dimension on the plan view is obtained. Can be generated, and the efficiency of floor area calculation work and design work can be improved.

The CAD for a unit building according to claim 5.
According to the system, only at least a part of the outer wall and the partition wall of the unit building designed on the plan view is selected, and at the time of printing the plan view, the selected wall is colored with a preset color. Therefore, it is not necessary to paint the wall after printing to identify the wall, and the design work efficiency can be improved.
