Abstract

PROBLEM TO BE SOLVED: To decrease an input operation man-hour and to simplify designing work. SOLUTION: A plan designing means 31 which designs a plan figure by arranging components on an internal plan of a building unit by using component data stored in a component information storage means is provided with a segment specifying means 42 which selects a desired segment out of segments representing the border of an area formed in the building through input operation for designating one arbitrary point on the segment. Consequently, since the segment can be selected only by designating the arbitrary point on the segment, both the ends of the segments need not be designated to decrease the input operation man-hour and simplify the designing work.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

[0001] 1. Field of the Invention [0002] The present invention relates to a CAD system for creating a plan view of a unit-type building which supports the operation of creating a plan view of a unit-type building formed by combining a plurality of box-like building units.

[0002]

2. Description of the Related Art In recent years, in order to increase the industrialization rate and shorten the construction period at a construction site, a unit construction method in which a rectangular parallelepiped building unit is manufactured in a factory in advance, and a plurality of these are combined at a construction site to construct a building. Used. As shown in FIG. 10, the building unit has a rectangular parallelepiped frame 9.
0, and the skeleton 90 includes pillars 91 erected at four corners.
A lower side upper beam 92 and a longer side upper beam 93 connecting between the upper ends of the columns 91; and a lower side lower beam 94 and a long side lower beam 95 connecting between the lower ends of the four columns 91. ing. Various components such as a ceiling surface material, a floor surface material, an outer wall material, a partition wall, and the like, which are not shown, are assembled to the skeleton 90, thereby forming each part of the building.

According to the unit-type building using such a building unit 9, since the building unit is manufactured in a factory, the work at the construction site is reduced, and there is an advantage that a high-quality building can be constructed in a short time. can get. However,
In addition to the advantage of improving the efficiency of construction work, in order to improve the efficiency of design work and manufacturing work, standardizing the components of building units and promoting the commercialization of unit-type buildings as products, It is difficult to sufficiently respond to the various demands of the above. For this reason, as in the case of a general custom-built building, even if the unit-type buildings are designed one by one according to the customer's requirements, the design work is supported so that the design work can be performed efficiently.
An AD system is used (Japanese Patent Laid-Open No. 8-14735).
No. 0).

[0004] This CAD system mainly performs a floor plan design. Basically, on a plan view of a building, parts such as partition walls, stairs, and doors arranged inside each floor of the building are provided. The floor plan is set while inputting. In a house, the plan is often changed in order for the customer to determine whether the usability is good or not while looking at the plan.
The use of the system makes it possible to easily and efficiently change the layout and the like. By the way, in the CAD system, when inputting a long part that needs to be set in length, for example, an upside frame or a strip-shaped side plate extending along the wall surface of the entrance continuously to the upside frame, in the plan view, the length is set in the plan view. A line segment representing a wall or the like on which a long component is to be installed is selected, a long component is input to this line segment, and then the set length of the long component is input.

For example, when designing a flat rectangular entrance surrounded by an upward frame and a side plate, a rectangular entrance area is set in a building on a plan view, and among the four sides which are the outer periphery of the entrance area, an upward frame is set. For example, one side is selected by designating each point at both ends of the line, and an ascending frame is input to the selected line segment, and then the length of the ascending frame is input. A side plate is set on the remaining line segment excluding the line segment on which the upward frame is set, and thereafter, the length of the side plate is input. The input position of this side plate is set by performing a selection operation to specify each point at both ends of each line segment, as in the case of the upward frame. After entering the ascending frame and the side plate, enter the entrance fitting into any of the line segments where the side plate is set in the outer periphery of the entrance area, and then reduce the length of the side plate by the dimension of the entrance fitting. Had gone.

[0006]

However, in order to input a long part, it is necessary to perform an operation of designating both ends of a line segment on which the long part is to be placed on a plan view. There is a problem that the number of input operation steps is increased. In particular, when a long component is input, the length of the component must be input after the input of the component, so that the design work is complicated. In addition, in the design of the entrance, the up frame and the side plate must be set individually, and the length of the side plate is reduced according to the dimensions after inputting the entrance fitting on the line where the side plate is set. Since the necessity arises, there has been a problem that it takes much more time for input.

SUMMARY OF THE INVENTION An object of the present invention is to provide a CAD system for creating a plan view for a unit-type building, which can reduce the number of input operation steps and simplify the design work.

[0008]

The present invention, which will be described with reference to the drawings, assists in creating a plan view of a unit-type building formed by combining a plurality of box-like building units 9, 9A and 9B. C for creating a floor plan of a modular building
An AD system 1 in which component information storage means 2 stores component data relating to components arranged in a building unit.
1 and a plan view design means 31 for arranging parts on the internal plane of the building unit and designing a plan view of the unit-type building using the part data stored in the part information storage means. The means accumulates data relating to long parts (51, 52) defined by the length, and the plan view designing means forms an area (R) formed by partitioning the internal plane of the unit building on the plan view. ) Represents a plurality of line segments R
A line segment specifying unit 42 for selecting a desired line segment from among 1, 1, R2, R3, and R4 by an input operation for specifying an arbitrary point on the line segment; and a line segment selected by the line segment specifying unit And component input means 43 for inputting the component data stored in the component information storage means.

Here, the long component is not a piece-shaped component such as furniture or a wash basin whose quantity is specified by the number, but a component whose quantity is specified by the length. , Skirting board, surrounding edge, etc. In the present invention, since the line segment can be selected simply by specifying an arbitrary point on the line segment by the line segment specifying means, it is not necessary to specify both ends of the line segment to be selected as in the related art. In addition, the number of input operation steps can be reduced, and the design work can be simplified.

The component input means may be configured to automatically set the length of the long component according to the length of the line when the long component data is input to the line. desirable. According to such a configuration, since the length of the long component is automatically set according to the length of the line segment only by inputting the long component data, the input operation of the length can be omitted. The number of input operation steps can be further reduced.

In this case, the part information storage means includes an up frame 51 and a side plate 5 installed along the boundary of the entrance area R.
It is preferable that data relating to No. 2 is stored. In other words, if a line segment representing the boundary of the entrance area is selected by the line segment specifying means and the input of the upward frame or the side plate is performed by the component input means, the entrance design work can be efficiently performed with a small number of input operation steps. .

At this time, the plan view design means removes, when the up frame is input to the line segment of the entrance area, the line segment to which the up frame is input from all the line segments representing the boundary of the entrance area. It is desirable to have side plate setting means 44 for automatically inputting the side plate to the remaining line segments and automatically setting the length of the side plate. By providing such side plate setting means, it is possible to omit the line segment selection operation and input operation for setting the side plate, so that the number of input operation steps can be significantly reduced, and the work efficiency of the entrance design can be significantly improved. it can.

The part information storage means stores data relating to the entrance fitting (99). The entrance fitting data includes a reduced dimension for reducing the length of the long member by a dimension corresponding to the entrance fitting. The data is added, and the plan view design means, when the entrance fitting data to which the reduced dimension data is added is input to the line segment where the side panel is input, reduce the length of the side panel based on the reduced dimension data. Is preferred. In this way, when inputting a front door, it is possible to eliminate the trouble of reducing the length of the side plate, and it is possible to surely prevent the occurrence of a design error because the user does not forget to change the length of the side plate.

The component information storage means 21 of the present embodiment includes:
In addition to the piece-shaped parts such as the entrance fittings described above, as long parts defined by the length, ascending stairs, side boards, baseboards, and surrounding edges installed along the boundaries of the area provided in the building Etc. are accumulated. Among them, the upward frame and the side plate are long components arranged along the boundary of the entrance area, and the upward frame 51 is installed at the boundary between the entrance 50 and the floor 59, as shown in FIG. The side plate 52 is located at the entrance 50.

Returning to FIG. 2, the component input means 43 inputs the long component data of the component information storage means 21 to the line segment selected on the plan view, and inputs the long component data in accordance with the length of the line segment. The length of the scale component is automatically set.
Further, when the front door design data to which the reduced dimension data is added is input on the line segment on which the side panel is set, the plan view design means 31 reduces the length of the side panel based on the reduced dimension data. Has become. That is, the plan view design means 31
When the component data to which the reduced dimension data is added is input, it is determined whether or not the designated installation position of the component is a line segment to which the long component has been previously input, and When the component is an input line segment, a process of automatically reducing the set length of the long component based on the reduced dimension data is performed.

In such a plan view design means 31, when an upward frame is inputted to a line segment representing the boundary of the entrance area, the upward frame is inputted among all the line segments representing the boundary of the entrance area. Side plate setting means 44 is provided for automatically inputting the side plate to the remaining line segment excluding the line segment and automatically setting the length of the side plate. That is, when a component is input by the component input unit 43, the side plate setting unit 44 determines whether the input component is an upward frame, and when the set component is an upward frame, Is configured to automatically set the side plate on the remaining portion of the boundary line including the input line segment.

Next, the operation of the present embodiment will be described using a specific example of 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. Such a plan view is designed in order from the lower floor of the building. 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. That is, it becomes possible to input various components including equipment such as stairs, elevators, toilets, and system kitchens, long components such as up frames and side plates, furniture, and the like. 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 part, first, a building unit to which the part is to be input is specified, then the installation position of the part is selected, and the part to be input is selected and input.

[Entrance Design Work] Next, as a specific example, a design work of a flat rectangular entrance in a unit-type building will be described. First, as shown in FIG. 5, on a screen S1 for designing the first floor of a unit building,
An entrance area R to be an entrance is set. The setting operation of the entrance area R is performed by designating, with the cursor C, positions of two points on the screen S1 which are both ends of a diagonal line of the area among the four corners of the entrance area R. That is, of the intersections of the grid module lines GS and GL (virtual reference lines of the installation positions of the components) previously set in the form of a lattice inside the building unit, the cursor C is moved to the intersection G1 which is the corner of the region R by a mouse or the like. It is moved to determine one point which is one end of a diagonal line of the entrance area R. Thereafter, the cursor C is moved to the intersection G2 which is the other end of the diagonal line having the intersection G1 determined earlier as one end, and the other point is determined. Then, in the building, the intersection G
A rectangular entrance area R having a diagonal line connecting the lines G1 and G2 is set. On the screen S1, four line segments R1, R2, R3, which represent the boundary of the entrance area R, as shown in FIG. R4 is displayed.

Next, an up frame as a boundary between the entrance and the floor is set to any of the line segments R1 to R4 of the entrance area R. For example, when the boundary between the entrance and the floor is represented by a line segment R1, the cursor P is moved to an arbitrary position P on the line segment R1 to designate the position P. Then, the line segment specifying means 42
Selects the entire line segment R1 including the point at the position P based on the input information of the position P, and selects the line segment R1 by indicating the line segment R1 with a display color different from that of the other portions. Let the operator confirm that it has been done.

Subsequently, from the component data stored in the component information storage means 21, the data of the upward frame is selected and the line segment R1 is selected.
To enter. Then, the component input unit 43 performs the setting registration of the upward frame, and automatically sets the length of the upward frame according to the length RL1 of the line segment R1. Further, the side plate setting means 44
Recognizes that the component input to the line segment R1 is an upward frame, and automatically sets the side plates to the remaining three line segments R2 to R4 except the line segment R1 in the entrance area R. At this time, the side plate setting means 44 determines the lengths RL2, RL of the line segments R2, R3, R4.
3, The length of the side plate is automatically calculated according to RL4. As described above, by performing the setting operation of the upward frame, the upward frame is registered in the line segment R1, and the line segment R2 other than the line segment R1 is registered.
The registration of the side plate to .about.R4 and the setting of the length of the up frame and the side plate are automatically performed.

Thereafter, the entrance sash to be installed at the boundary of the entrance area R is input. That is, when the boundary between the entrance and the outside is represented by a line segment R3, for example, the cursor C is moved to a position Q on the line segment R3 and the position Q is designated to select the line segment R3. The entrance sash data is selected from the component data stored in the component information storage means 21 and input to the line segment R3. Then, the component input unit 43 sets and registers the entrance sash in the line segment R3, and displays the entrance sash 99 on the line segment R3 of the screen S1, as shown in FIG. Further, since the reduced dimension data described above is added to the data of the entrance sash 99, the plan view design means 31
Determines whether a long part is registered in the line segment R3. Since the side plate which is a long part is set in the designated line segment R3, the plan view designing means 31 calculates the length of the side plate automatically set by the side plate setting means 44 based on the reduced dimension data at the entrance. The sash size is reduced by 99L and reset automatically. As a result, the entrance sash is registered in the line segment R3, and the length of the side plate is set to a length corresponding to the entrance sash.

[Stair part input work] Next, a case where stairs 65A and 65B are input to each floor of a two-story unit building will be described. That is, as shown in FIG. 8A, the stairs 65A are selected and displayed at an arbitrary position in the first-floor building unit 9A on the screen S2 displaying the first-floor plane, and the lower-floor stairs 65A are displayed. Set the position. Thereafter, when a plan view of the upper floor is created, as shown in FIG. 8B, on the screen S3 displaying the second floor plane, the stairs 65A on the lower floor of the building unit 9B on the building unit 9A
The stairs 65B for the upper floor are selected and displayed at the position corresponding to the above, and the position of the stairs 65B for the upper floor is set. At this time, in conjunction with the input operation of the upper-floor stairs 65B, the area is automatically set as the atrium space 66 as shown in FIG. That is, in the case of FIG. 8, the floor of the input floor (the second floor) and the lower floor (the first floor) are stored in the component data 60 of the upper floor staircase 65B.
Since the stairwell area setting data 64 that sets the ceiling of the stairwell as the stairwell is registered (see FIG. 3), the stairs 65B
In the ceiling and floor in conjunction with the input operation of
6A and 66B are set.

According to the present embodiment, the following effects can be obtained. That is, the line segment specifying unit 42
The line segment selection operation can be performed simply by specifying an arbitrary point on the line segment, so that it is not necessary to specify both ends of the line segment to be selected as in the conventional case. Can be simplified.

The component input means 43 is configured to automatically set the length of the long component according to the length of the line when the long component data is input to the line. By simply inputting the long part data, the length of the long part can be automatically set in accordance with the length of the line segment, so that the operation of inputting the length can be omitted, and the number of input operation steps can be further reduced.

Further, since the component information storage means 21 stores data relating to the upward frame 51 and the side plate 52 installed along the boundary of the entrance area R, the line segment identification means 42 determines the boundary of the entrance 50. Since the line segments R1 to R4 to be represented can be selected and the input of the upward frame 51 and the side plate 52 can be performed by the component input means 43, the design work of the entrance 50 can be efficiently performed with a small number of input operation steps.

At this time, since the plan view design means 31 has the side plate setting means 44 for automatically inputting and setting the length of the side plate, the selection operation and the input operation of the line segments R1 to R4 for setting the side plate are performed. Can be omitted, the number of input operation steps can be greatly reduced, and the work efficiency of the entrance 50 design can be significantly improved.

Then, to the entrance fitting data, reduced dimension data for reducing the length of the long member by a dimension corresponding to the entrance fitting is added, and the part input means 43 inputs the entrance to which the reduced dimension data is added. When the fittings data is input to the line segment where the side plates are input, the length of the side plates is reduced based on the reduced dimension data, so that when inputting the entrance fittings, the labor of reducing the length of the side plates can be omitted, Since it is not necessary to change the length of the side plate, it is possible to reliably prevent a design error.

The staircase part data 60 for the upper floor includes:
In addition to the part code 61, the stairwell area setting data 64 for setting the ceiling and floor as a stairwell is added. Therefore, when the part data 60 is input, that is, the position setting of the staircase 65B for the upper floor is performed. When performed, the area 6 corresponding to the stairs 65B is linked to the input operation.
6A and 66B are set as the atrium space 66. Therefore, it is not necessary to perform the setting operation to the effect that the area of the stairs 65A and 65B is a stairwell, so that the number of input operation steps can be reduced and the input operation error can be reduced.

It should be noted that the present invention is not limited to the above-described embodiment, but includes other configurations capable of achieving the object of the present invention, and also includes the following modifications.
That is, in the above-described embodiment, a case has been described in which the line segment specifying unit selects a line segment representing the boundary of the entrance region. However, the region is not limited to the entrance region, and may be, for example, a region that becomes a living room or a carport. It may be an area or the like. That is, the present invention can be applied to a case where a line segment on a plan view is selected to set a partition wall or a long part at a boundary between these regions. In addition, the long part is not limited to the upward frame and the side plate.For example, at the boundary of the living room area, other long parts such as a baseboard and a surrounding edge may be input. Automatic input allows efficient input.

Although the plan view designing means of the above-described embodiment includes the side plate setting means for automatically inputting the side plate and automatically setting the length thereof, the side plate setting means may be omitted. In this case, similarly to the input of the upward frame, a line segment indicating the boundary of the entrance area may be selected by the line segment specifying means, and the side plate may be input to the line segment.
