Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a CAD system for creating a drawing of a unit-type building, which supports an operation of designing a drawing of the unit-type building using a computer. In detail, when building a unit type building by combining building units, it is possible to design a unit type building rich in variations without increasing the number of items in unit unit data on the unit unit of the building unit A possible CAD system.

[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 shown in FIG. 11, the building units constituting the unit-type building have four pillars 11 at the four corners.
And a frame 14 formed in a box shape (substantially rectangular parallelepiped) including an upper beam 12 and a lower beam 13 for connecting between the upper end portion and the lower end portion of these pillars 11, respectively. A living room or the like is formed by attaching a ceiling surface material or a floor surface material that is not used, an outer wall material, a partition wall, and the like. According to such a unit-type building, since most of the work conventionally performed at the construction site can be performed at the factory, the work at the construction site can be significantly reduced, and a high-quality building can be built in a short time. There is an advantage.

[0003] In order to secure the advantages of this unit-type building, products (unit-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 limited. However, in this case, it is difficult to sufficiently respond to various requests from customers. Therefore, as in the case of general custom-built buildings, a CAD system that supports the design work is used to design the unit-type buildings one by one according to the customer's requirements so that the efficiency of the design work is sufficiently ensured. ing.

[0004] In this CAD system, the floor plan is mainly designed, and in a house, the plan view is often changed because the customer judges the usability of the house while looking at the plan view. After arranging the building units on each floor, the floor plan is designed while inputting parts such as partition walls, stairs, elevators, doors, system kitchens, baths, and toilets on the floor plan.

[0005]

By the way, an ordinary standard building unit (having four columns, a floor and a ceiling, and having a width, length and height of a predetermined number of modules each having a reference size as one module). In some cases, designing a building using only a building unit that has been completed may not be able to adequately meet customer requirements. For example, if it is desired to form a stairwell in a building, it is not possible to cope with it only with normal standard building units. This is because, in a normal standard building unit, the height from the floor to the ceiling is set to a certain dimension, so that a sufficient ceiling height cannot be obtained. In addition, when a plurality of building units are stacked, a normal standard building unit alone may exceed the height limit of the building.

Therefore, apart from the normal standard building unit, there is a ceiling blown-out building unit without a ceiling (that is, an atrium), an intermediate floor building unit for a blow-out where the floor is located at an intermediate position in the height direction of the building unit, It is conceivable to prepare a low-rise building unit or the like whose overall height is lower than the height of a normal standard building unit, but this increases the number of items. This causes a problem that the item database becomes large, and even if one item is selected from many items, an access time is required and errors are increased.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a conventional problem and prevent the increase in the number of items while designing a unit-type building with various variations. Is to provide.

[0008]

A CAD system for creating a drawing of a unit building according to the present invention will be described with reference to the drawings. The CAD system creates a drawing of a unit building formed by combining a plurality of box-like building units. A unit-building information drawing means for storing unit-building data of a unit building of the building unit, the unit-building information storing means 24 comprising: And a design unit 31 for designing a drawing of the unit building using the unit precursor data stored in the unit 24. The design unit 31 reads the unit precursor data from the unit precursor information storage unit 24 and reads the unit precursor data. A readout means 37 for displaying, and an arbitrary area for the unit body data read out by the readout means 37, Attribute specification means 38 to specify the attributes
And attribute changing means 39 for changing the area specified by the attribute specifying means 38 to the specified attribute.

According to such a configuration, first, the readout means 37 reads out and displays any unitary body data from the unitary body information storage means 24. When an arbitrary area is specified by 38 and the attribute of the area is specified, the area specified by the attribute changing means 39 is changed to the specified attribute and registered. Therefore, since there is no need to prepare many different types of unit vehicle data from the beginning, it is possible to design a unit-type building with a variety of variations while preventing an increase in the number of items. This means that the unit vehicle body information storage means 24, which is an item database, does not need to be large, and the selection of an item requires a short access time and can reduce errors.

In the above configuration, the attribute designating means 3
It is desirable that 8 can specify whether the ceiling 15 is present or not as an attribute of the designated area. For example, it is desirable that if the read unit body data has a ceiling, it is possible to specify that there is no ceiling, and if the read unit body data has no ceiling, it is desirable to be able to specify that there is a ceiling. In this case, when the specified area has no ceiling, it is more preferable that the presence or absence of the intermediate beam can be specified in the area of the ceiling. In this way, even when a wall is provided in the middle of the atrium, the upper end of the wall can be supported by the intermediate beam.

It is preferable that the attribute designating means 38 can designate, as an attribute of the designated area, that the floor 16 is located at an intermediate position in the vertical direction of the unit body data. In this case, by combining the above-mentioned unitless body data without ceiling on the lower floor,
A blow-through can be formed. Further, it is preferable that the attribute specifying means 38 can specify the height of the unit body data as an attribute of the specified area. In this way, for example, the unit building data of the standard building unit is changed to a low-rise building unit whose height is lower than the height of the standard building unit, or a floor-rise building whose height is higher than the height of the standard building unit. Create and register unit unit data for units.

Next, the operation of the present embodiment will be described based on specific examples. For example, as shown in FIGS.
When designing a building by stacking and arranging a plurality of building units U1 to U3, one of the building units U3a located at the center of the top floor is a ceiling blown-out building unit UB having a ceiling, and the other building unit U3b is connected to the ceiling. When the building unit UC having a central beam with an open ceiling and an intermediate beam 17 having an open ceiling is to be formed, the following operation is performed.

First, the unit generator data of the standard building unit UA is read from the unit generator information unit 24 by the reading unit 37, and the unit generator data of the standard building unit UA is arranged on each floor. In the plan view, the attribute of the unit body data of the standard building unit UA is changed. To this end, the entire ceiling surface (shaded area) is specified for the unit body data of the standard building unit UA disposed at the position of the building unit U3a (points P to P).
Q) and designates that the attribute of the designated area is “no ceiling”. Then, as shown in FIG. 6, the unit body data of the ceiling open building unit UB having no ceiling (atrium) is changed and registered (the unit body data of the standard building unit UA is changed).

Further, for the unit body data of the standard building unit UA arranged at the position of the building unit U3b, the entire ceiling surface (shaded area) is designated, and the attribute of the designated area is "no ceiling" and Then, it is specified that the intermediate beam 17 is located in the middle of the blow-by area. Then, the unit body data of the standard building unit UA is changed, and as shown in FIG.
Is changed to unit fuselage data of a building unit UC with a blown intermediate beam (the unit fuselage data of the standard building unit UA is changed) and registered. In this way, the building shown in FIGS. 4 and 5 can be designed by changing the attribute of the unit building data of the standard building unit UA by using the data.

Also, as shown in FIGS. 8A and 8B, a building is designed using a blow-off intermediate floor building unit UD in which at least a part of the floor 16 is located at an intermediate position in the vertical direction of the building unit. If so, do so as follows. First, after the standard building unit UA is read from the unit body information unit 24 by the reading unit 37, FIG.
As shown in (C), a part of the floor of the standard building unit UA is designated (shaded area), and the attribute of the designated area is designated as an intermediate floor. In this case, floor height position information is input. Then, as shown in FIGS. 8A and 8B,
A part of the floor 16 is changed and registered as unit body data of the blow-off intermediate floor building unit UD located at the middle position in the vertical direction of the building unit.

Also, as shown in FIG. 9A, a skip-floor building is designed using a plurality of standard building units UA and a low-rise building unit UE whose height is lower than the height of the standard building unit UA.

A wide variety of unit-type buildings can be designed.

That is, when the unit precursor data is read out from the unit precursor information storage means 24 and displayed, and an arbitrary area is designated for the unit precursor data and the attribute of the area is designated, the attribute changing means 39 The area specified by is changed to the specified attribute. Therefore, since it is not necessary to prepare many different types of unit generator data from the beginning, it is possible to form a unit-type building with a variety of variations while preventing an increase in the number of items. This means that the unit vehicle body information storage means 24, which is an item database, does not need to be large, and the selection of an item requires a short access time and can reduce errors.

Further, the attribute designating means 38 designates that there is no ceiling for the read unit body data of the building unit, and if there is no ceiling, the intermediate beam 1 is placed in the area of the ceiling.
7 can be specified, the floor 16 can be specified to be at an intermediate position in the vertical direction of the building unit, and the height of the building unit can be specified to be smaller than the height of the standard building unit. It is possible to change and register the unit precursor data of the building units to the unit precursor data of a plurality of types of building units having different attributes.

Specifically, when the designation that there is no ceiling in the designated area is performed, the attribute is changed to the unit body data of the ceiling blow-off building unit UB shown in FIG.
In addition, when there is no ceiling in the designated area and the designation that the intermediate beam 17 is present in the area of the ceiling is performed, FIG.
The attribute is changed to the unit carcass data of the building unit UC with the blowout intermediate beam shown in FIG. Therefore, a building as shown in FIGS. 4 and 5 can be designed using the standard building unit UA.

If the designation that the floor of the designated area is the middle position in the vertical direction of the building unit is made,
Intermediate floor building unit UD for blow-off shown in FIGS. 8 (A) and 8 (B)
The attribute is changed to unit fuselage data. Therefore, if the unit body data of the ceiling blow-off building unit UB is combined therewith, a building having a stairwell having a height from the floor to the ceiling of about 1.5 units can be configured. Also, the height of the building unit is the standard building unit UA.
Is specified, the attribute is changed to the unit body data of the low-rise building unit UE. Therefore, by utilizing this attribute change, a building with a skip floor as shown in FIG.
Can be configured using the unit body data of the unit.

When calculating the total floor area, if the warehouse 2F (instruction that the height is lower than the standard building unit and is not included in the floor area) is set as an initial value, the total The total floor area can be easily calculated because the floor area of the other floor is integrated without calculating the floor area of the floor.
