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 floor plan of a unit building, which supports the operation of designing a floor plan of the unit building using a computer. More specifically, the present invention relates to a CAD system that reduces the number of input operation steps and the number of input operation errors when inputting an elevator component, a staircase component, or the like to an internal plane of a building unit.

[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. 8, the building units constituting the unit-type building include pillars 11 at four corners,
The frame 11 includes a frame 14 having a substantially rectangular parallelepiped shape including an upper beam 12 and a lower beam 13 for connecting between upper ends and lower ends of the pillars 11. The living room and the like are formed by attaching face materials, outer wall materials, partition walls, and the like. According to such a unit-type building, most of the work conventionally performed at the construction site can be performed at the factory,
There is an advantage that work on a construction site can be significantly reduced, and a high-quality building can be constructed in a short time.

[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. The floor plan is designed while inputting parts such as partition walls, stairs, elevators, doors, system kitchens, baths, and toilets arranged on each floor of the building on the floor plan of the building.

[0005] By the way, regarding the input of the elevator parts, for each floor, after inputting the elevator parts on the plan view, the position of the elevator door parts is input, and then the area of the elevator is specified. A setting operation has been performed to the effect that the area is a blow-by area. Also, as for the input of the staircase component, after the staircase component is input on the plan view, an operation of designating that the region of the staircase is a blow-by region is performed.

[0006]

In the case of inputting a part that requires a stairwell, such as an elevator part or a staircase part, conventionally, the input of each part and the fact that the area is a stairwell is described. Since the input operation must be performed separately from the setting operation, the number of input operation steps increases accordingly.
Moreover, when each part is input on the plan view, the parts are displayed on the plan view, so that it looks as if the setting of the blow-by area has been completed, and that the area is a blow-by space. Often, you forget the setting operation.

SUMMARY OF THE INVENTION An object of the present invention is to solve such a conventional problem, and to reduce the number of input operation steps and the number of input operation errors simultaneously.
An AD system is provided.

FIG. 1 is a plan view of a unit-type building formed by combining a plurality of box-like building units. A CAD system 1 for creating a floor plan of a unit-type building that supports a work to be created, wherein component information storage means 21 stores component data relating to components arranged in the building unit, and the component information storage means 21 stores the component data. A plan view design means 31 for designing the plan view of the unit-type building by arranging the parts on the internal plane of the building unit using the obtained part data,
Of the component data stored in the component information storage unit 21, for the component data 50 and 60 that require a stairwell, the stairwell area setting data 54 and 64 are added. When component data 50 and 60 to which the above-mentioned blow-by area setting data 54 and 64 are added are input to the internal plane of the unit, the area is set as a blow-by area.

According to such a configuration, simply by inputting the component data 50 and 60 that require the space, the area is automatically set as the space.
In addition to inputting the component data 50 and 60, it is not necessary to perform a setting operation for the blow-by space, so that the number of input operation steps can be reduced and, at the same time, input operation errors can be reduced.

In the above configuration, the component data 50 and 60 to which the blow-by area setting data 54 and 64 are added include components for elevators and components for stairs. In the case of an elevator part, the plan view design means 31 may set the area of the elevator part as a blow-by area when the door 56 of the elevator part is input.

Also, blow-by area setting data 54, 64
It is preferable to use any of data for setting both the ceiling and floor of the building unit as a stairwell, data for setting only the ceiling of a building unit as a stairwell, and data for setting only the floor of a building unit as a stairwell. In this way, for example, when an elevator is provided in a three-story building, for the building units on the first and second floors, both the ceiling and the floor can be set as stairwells,
For the building unit on the third floor, only the floor can be set as a stairwell. When a staircase is provided in a two-story building, only the ceiling of the first-floor building unit can be set as a stairwell, and only the floor of the second-floor building unit can be set as a stairwell.

Next, the operation of the present embodiment will be described with reference to a specific example regarding the design of a unit building. When designing a floor plan of a unit-type building with the CAD system 1 described above, design work such as exterior wall input work, partition wall input work, part input work, part input check work, and the like is performed. Hereinafter, among these operations, a component input operation which is a feature of the present invention will be described.

When the input operation of the outer wall and the input operation of the partition wall are completed, the input operation of the parts can be performed. In other words, it becomes possible to input parts including equipment and furniture such as elevators, stairs, toilets, and system kitchens. In this input operation, an operation of selecting a part and an operation of specifying its installation position are performed. That is, in inputting a component, first, a building unit to which a component is to be input is designated, then a component to be input is selected and input, and subsequently, an installation position of the component is input.

For example, when an elevator is provided on each floor of a three-story unit building, the operation is performed as follows.
That is, as shown in FIG. 5, each floor (1F, 2F, 3F)
F) corresponding building units 101, 102 above and below, respectively.
After selecting and displaying the elevator 55 at an arbitrary position in the 103, the door 5 which is an accessory part of the elevator 55 is selected.
6 is moved to an arbitrary position and set. Thereby, the coordinate positions of the elevator 55 and the door 56 are set.

At this time, in conjunction with the input operation of the door 56, the area is automatically set as a colonnade. That is, in the case of FIG. 5, for the building units 101 and 102 on the first floor 1F and the second floor 2F, the open-air area setting data 54 for setting both the ceiling and the floor as the open-air are registered in the elevator part data 50. From
In conjunction with the input operation of the door 56, both the ceiling and the floor are set as a stairwell. For the building unit 103 on the third floor and the third floor, the elevator part data 50
Since the open-air area setting data 54 for setting only the floor as the open-air is registered in the area, only the floor is set as the open-air in conjunction with the input operation of the door 56.

After designing the plan view of the first floor 1F,
When designing the floor plan of the second floor 2F, instead of arranging and designing each part from the beginning, the first floor 1F floor plan is displayed as it is as the second floor 2F plan view (copied), and changes are made. By doing so, the design work can be performed more quickly.

When a staircase is provided in a unit-type building, it is performed as follows. That is, as shown in FIG. 6, the stairs 65 are selected and displayed at an arbitrary position in the building unit 100, and the position of the stairs 65 is set. At this time, the area is automatically set as an atrium space in conjunction with the input operation of the stairs 65. That is, in the case of FIG. 6, with respect to the building unit 100, the stairwell part data 60 is registered with the stairwell area setting data 64 that sets only the ceiling as a stairwell, so that the floor unit is linked to the staircase 65 input operation. Only the stairwell is set.

By the way, in the component data, a building unit in which a carport and a living room are divided and provided in one building unit is prepared. In the case where a design in which a carport and an entrance are divided in one building unit using this building unit is performed, the design is performed as follows. That is, as shown in FIG. 7A, the attribute is changed for the building unit 104A having the carport 105 and the living room 106. Then, as shown in FIG.
06 is registered with the attribute changed as the entrance 107. At this time, the part of the entrance 107 is divided as an entrance soil 107a and an entrance porch 107b as needed.

According to the present embodiment, simply by inputting the component data 50, 60 that requires a through-hole space, the area is automatically set as a through-hole region. In addition, it is possible to eliminate the need for an input operation for setting an atrium space. Therefore, the number of input operation steps can be reduced, and input operation errors can be reduced.

For example, elevator component data 50
In addition to the part code 51, the ceiling and the open-air area setting data 54 for setting the ceiling as an open-air space are added, the input operation of the part data 50, that is, with the accessory parts of the elevator 55, When the position of a certain door 56 is set, the area is set as an atrium space in conjunction with the input operation of the door 56. Therefore, it is not necessary to perform the setting operation to the effect that the area of the elevator 55 is a stairwell, so that the number of input operation steps can be reduced and the input operation error can be reduced.

Moreover, as the atrium area setting data 54, data for setting both the ceiling and the floor of the building unit as the atrium, data for setting only the ceiling of the building unit as the atrium, and setting only the floor of the building unit as the atrium. Since any of the data to be registered can be registered, it is possible to set an optimal atrium space according to the floor. For example, when an elevator is provided in a three-story building, both the ceiling and the floor can be set as a stairwell for the first and second floor building units.
For building units on floors, only floors can be set as stairwells.

At this time, after designing the first floor plan,
When designing the floor plan of the floor, instead of arranging and designing each part from the beginning, the first floor plan can be displayed (copied) as it is as the second floor plan.
If changes are made from this state, design work can be performed more quickly.

The part data 60 for the stairs is added with the part code 61 and the blow-by area setting data 64 for setting the ceiling or the ceiling as a stairwell. When the operation is performed, that is, when the position of the stairs 55 is set, the area is set as an atrium space in conjunction with the input operation. Therefore, since it is not necessary to perform the setting operation to the effect that the area of the stairs 65 is a stairwell, the number of input operation steps can be reduced, and the input operation error can be reduced.

Moreover, as the atrium area setting data 64, data for setting both the ceiling and the floor of the building unit as the atrium, data for setting only the ceiling of the building unit as the atrium, and setting only the floor of the building unit as the atrium. Since any of the data to be registered can be registered, it is possible to set an optimal atrium space according to the floor. For example, when stairs are provided in a two-story building, only the ceiling can be set as a stairwell for the first-floor building unit, and only the floor can be set as a stairwell for the second-floor building unit.

Although the present invention has been described with reference to the preferred embodiments, the present invention is not limited to these embodiments, and various improvements and design changes may be made without departing from the spirit of the present invention. It is possible. For example, in the above-described embodiment, the plan view set by the plan view design means 31 includes information in the up-down direction (that is, the point where the ceiling or floor of the building unit is set as a stairwell). An elevation can also be created based on this information.
