Description

  The present invention relates to a technique for changing or reducing a floor plan especially for a narrow area. More specifically, based on the floor plan of the building created using CAD (Computer Aided Design), the range that can be reduced for each room is calculated as a variable area, while the area that the customer does not want to reduce, or In addition, an architectural plan that uses the non-reducible area as an invariable area and is attributed to each room as the search target data is used as the search target data. The present invention relates to a technique for extracting data to be searched as a corresponding plan if there is a possibility that the data will be stored there.

Conventionally, a floor plan search for a building using a computer system is a database containing standard plans, while a floor plan desired by a customer is conditionally set and input as search target data. The search target data that satisfies the conditions is extracted from the database. For example, when the floor plan and the depth are determined by the search means as described above, the standard plan can be extracted when the front and depth of the standard plan do not fit within the specified dimensions. Can not.
In particular, the standard plans are planned and designed with a margin assuming a site with a certain size, and there are few standard plans for narrow spaces.

JP-A-5-73626 ("Claim 1")

  However, according to the search means as described above, only the standard plan satisfying the size conditions of the frontage and the depth set by the customer is extracted, and the search for the narrow plan or the standard plan is searched depending on the site shape. The target search is not possible.

  Even if the frontage and depth dimensions do not fall within the specified range, if the possibility of reduction hidden in the plan can be considered in the search stage, it can be searched even if it is outside the specified dimensions to some extent. It should be. Therefore, the present application enables such a search, so that one standard plan can be virtually made into 3 plans and 4 plans, so that even in a search for narrow land without increasing the burden on the system, The goal is to develop a system that enables efficient wide-ranging searches.

In order to solve the above-mentioned problem, the building plan allowable range search system according to claim 1 is a system for searching a floor plan of a building that can be applied to a narrow area by a computer, and is created by CAD. This means that the floor plan of the building is stored as search target data, the minimum dimension value (length and width) preset for each room type, and the structure such as stairs or the Building Standards Act. A non-reducible area, a means for storing as attribute information subordinate to the floor plan, a means for inputting a frontage, a depth length, or an area as a first search condition, a room where the customer does not request reduction The invariant area of the second search condition is input as a second search condition, and the stored floor plan is received as the attribute of the first search condition and the second search condition. Means for sequentially reading together with information, and each read floor plan includes areas not included in the area formed by extending the non-reducible area and the invariable area according to the second search condition to both sides in the frontage direction The minimum dimension value of the room arranged in (1) is extracted, and based on this minimum dimension value, the non-reducible area and the invariable area are not reduced and deformed, and the non-reducible area is fixed, and this non-reducible area is fixed. The room is reduced to the maximum in the depth direction so as to be compressed toward the area, and the non-reducible area and the invariable area according to the second search condition are extended to both sides in the depth direction. A minimum dimension value of a room arranged including an area not included is extracted, and the non-reducible area and the invariable area are not reduced and deformed based on the minimum dimension value. Allow the minimum value of the frontage, the length of the frontage, or the area obtained by maximizing the room in the frontage direction so that the non-reduction area is fixed and compressed toward the non-reduction area. The lower limit of the range is calculated for each floor and the calculated lower limit of the allowable range for each floor is compared with each other on the upper and lower floors, and the largest value is calculated as the lower limit of the allowable range for the entire building plan. Means and the calculated lower limit value of the entire allowable range of the building plan is compared with the input first search condition, and if the first search condition is satisfied, the floor plan is extracted as a search result And a means for performing the above.

Further, the building plan allowable range search system according to claim 2 is the configuration according to claim 1, wherein the floor plan extracted as a search result is converted into a frontage, a depth length, or a depth satisfying the first search condition. The gist of the invention is that it further comprises means for reducing the display in the frontage direction and the depth direction as much as possible so as to have an area.

Further, the building plan allowable range search system according to claim 3 is the configuration according to claim 2, wherein the first search condition is not satisfied by the lower limit value of the calculated allowable range of the entire building plan. The gist of the present invention is further provided with means for displaying a lower limit value of the allowable range of the entire building plan .

  According to the present invention, in the search for determining the standard plan from the frontage, depth, and area, even if the specified frontage, depth, and area are less than the standard plan, the difference can be considered. If there is, it can be extracted as a search target.

In addition, by considering the possibility of reduction for one standard plan, the plan can be virtually made into 3 plans and 4 plans. Therefore, it is possible to accumulate building plans without increasing the data burden on the computer system, and a wide range of searches can be efficiently performed.
Furthermore, regulations such as floor area ratio and building coverage ratio are important factors in planning in narrow spaces, but it is also possible to search for plans on the basis of the standard area under these laws and regulations, and to quickly and flexibly meet individual site conditions. The corresponding plan can be presented.

  In particular, considering the housing situation in Japan, the number of plans that can be presented will increase all at once due to the large number of customers who have to build in narrow spaces. It also leads to a sense of sensation, which also spurs sales activities. Therefore, there is a significant difference in the number of contracts for housing compared to a contractor who performs a search that does not depend on the present invention.

  Furthermore, since the present invention has a function not intended for reduction in the room or area desired by the customer, a plan in accordance with the customer's request can be obtained without ignoring individual attention even if it becomes narrow. It becomes possible to propose.

  FIG. 1 is a block diagram of a building plan search system according to the present invention. In the system according to the present invention, the storage device (2) is connected to the programmed main control unit (1) for controlling the system, and the main control unit (1), as shown in FIG. Are connected to an input device (3) composed of a pointing device such as a keyboard and a mouse, a display device (4) for monitoring input data and a search result, and an output device (5) for outputting the search result.

The main control unit (1) is necessary for operating a control program such as an OS (Operating system) and various means for causing the program according to the present invention to function, as well as a program and a system that define the processing procedure of the means. Various means are stored.
In addition, other components such as an internal memory for temporarily storing various data and hardware and software necessary for operating the computer system and executing the program are naturally included.

  Note that the present system is not limited to the above configuration, and may be another known configuration. That is, a program or a file related to the present system is recorded on a computer-readable recording medium such as a CD-ROM and can be installed and used on another computer, or a distribution server device can be used to request a distribution destination. Depending on the situation, it is possible to download a program or a file related to the present system to a memory of another computer via a network, or to use only the function.

The “minimum dimension that constitutes a room for each room type” described in claim 1 and other claims means that for each room related to a floor plan of a building created by CAD, the room is reduced. It shows how far it can be reduced. In the case of actual reduction, the ratio is not limited to the same aspect ratio, but may be a different ratio.
Therefore, for example, when creating a plan, what was “Japanese-style room / 6m × 6m” may be the set minimum dimension “Japanese-style room / 3m × 3m”, or “Japanese-style room / 4.5m × 3m”. Well, ensure optimal space considering search conditions.
In addition to the vertical and horizontal lengths, the elements that specify the size of the room may be other factors such as the number of tatami mats, the area, and the distance from the center of gravity of the room, as described in claim 3.

  The “non-reducible region” described in claim 1 and other claims refers to a region that cannot be reduced or deformed in terms of structure such as stairs or in the Building Standard Law, and is not a reduction target.

  The “invariant area information” described in claim 1 and other claims is specified based on the customer's request, and refers to area information regarding rooms, areas, and facilities that are not reduced. The area information is given priority. The permissible range for each floor is calculated for the area other than the area information.

  The “deformable region” described in claim 1 and other claims refers to a region without any hatching indicated by R1, R2, and R3 in FIG. To be reduced.

The “acceptable range for each floor” described in claim 1 and other claims means that, for each floor, the minimum dimension of each room included in the deformable area is extracted, and how much can be reduced for each floor. This is indicated by a numerical range, and for example, “frontage = 8-12 m” and “depth = 6-7 m” are calculated.
In this case, “frontage = 8 m” and “depth = 6 m” are minimum dimension values that are the reduction limits, and “frontage = 12 m” and “depth = 7 m” are the dimensions at the time of plan creation or the dimensions at the time of plan creation. A value obtained by calculation as a reference.

The “acceptable range for the entire building plan” described in claim 1 and other claims is the extent to which the entire building plan is calculated considering the allowable range for the upper and lower floors after calculating the allowable range for each floor. The numerical range indicates whether or not reduction is possible.
At the time of calculating the range, if the allowable ranges are different between the upper and lower floors, the allowable ranges are compared in the frontage and depth directions, and an appropriate value is calculated as the allowable range for the entire building plan. For example, when the plan is a two-story building and the allowable range in the frontage direction is “8 to 12 m” for the first floor, “10 to 12 m” for the second floor, The range is “10-12 m”.
In addition, since the position of a room installed across the upper and lower floors such as a staircase or a vent can not be shifted, the entire allowable range is calculated in consideration of this.

  The “search condition upper consisting of frontage, depth length, and area information” described in claim 1 and other claims is appropriately input by an input device (3) such as a keyboard and a mouse constituting the system, Although it is set according to the operator's request, as a variation of the present invention, when a designer creates a building plan with CAD, it receives the input site information and automatically provides information on the frontage, depth, and area of the site. It is also possible to recognize and extract an existing building plan suitable for the site.

A first embodiment of the present invention will be described with reference to FIGS.
The present embodiment is a search for extracting a building plan from information on the frontage and depth length set as a search condition, and the search condition is selected from various building plans already created and accumulated by CAD. The present invention relates to a technique for searching for a plan that satisfies or is likely to be satisfied.
In this system, it is the designer who creates the floor plan using the CAD function, but the operators who perform the search operation are designers, customers, coordinators, and the like.

  1 is a diagram showing the configuration of a system according to the present invention, FIG. 2 is a flowchart showing the flow of processing, FIG. 3 is a floor plan of a plan created by CAD, FIG. 4 is a reference diagram showing variable areas, and FIG. FIG. 6 is a reference diagram showing a reduction, floor plan is reduced, FIG. 7 is a reference diagram showing a screen displaying search results, and FIG. 8 is a reference diagram showing a screen displaying a search result list.

  In the figure, (1) is a main control unit, (2) is a storage device, (3) is an input device, (4) is a display device, (5) is an output device, (P) is between the floors, and (Q) is a staircase. , (R) is a deformable region, (S) is a reduced region, and (t) is a line indicating the original outline.

Prior to the search, various floor plans for the building have been created by the CAD function of this system (S101), and are stored in the storage device (2) as the data to be searched. The minimum dimension that configures the room for each type is set by the setting means related to this system (S102), and the non-reducible area such as stairs (Q) that does not change the dimension at the time of plan creation is specified by the specifying means. It is specified (S102) and stored in the storage device (2) as attribute information subordinate to the plan (S103).
In the present embodiment, the floor plan of the first floor portion of the building is as shown in FIG. 3, and the building has two floors.

Next, setting of search conditions will be described.
First, the frontage and depth length desired by the operator (hereinafter referred to as search condition A) is set by the setting means according to the present system, and is input by the input means (S104). Further, in response to the operator's request, invariant area information (hereinafter referred to as a search condition B) that does not reduce for a specific area, room, or facility is set by the setting means and input by the input means (S104). In this embodiment, “between floors” (P) is set and inputted as the invariant information.
In this embodiment, the length of the frontage and the depth is set as the search condition former, but it is also possible to set the area such as the total floor area and the building area.

Next, the present system receives input information of the set search conditions A and B, and extracts one of the building plans stored in the storage device (2) (S104a). The system receives the search condition B and the non-reducible area information in the attribute information, and recognizes the deformable area for the plan (hereinafter referred to as plan 1 in the present embodiment) by the recognition means.
It should be noted that the deformable region is a region where no pattern is given in addition to the diagonal line in FIG. 4 and is a region specified by R1, R2, and R3. Here, taking the stairs (Q) as an example, the region (Y) cannot be reduced in the depth direction, and the region (Z) cannot be reduced in the frontage direction. The same applies to “between floors” (P).

Next, calculation of the allowable range will be described.
The minimum dimension value is extracted for the room included in the recognized deformable area, in the present embodiment, “living room” and “Japanese room”, and the allowable range as the first floor based on the minimum dimension value. Is calculated (S105).
Similarly, for the second floor part (the floor plan is omitted), the allowable range as the second floor is calculated (S105). If the allowable range is different between the first floor and the second floor, the allowable range is set for each of the frontage and the depth direction. Compare and calculate an appropriate value as the allowable range for the entire building plan. For example, if the allowable range in the frontage direction is “8 to 12 m” on the first floor and “10 to 12 m” on the second floor, the allowable range in the frontage direction as the entire building is “10 to 12 m”.
Furthermore, since the portion of the stairs (Q) extends over the upper and lower floors and the position thereof cannot be shifted, the allowable range as the plan 1 is calculated in consideration of this (S106).

Next, when the comparison condition A and the calculated allowable range as the plan 1 are compared by the comparison means according to the present system, the upper exceeds the allowable range or is within the allowable range (S107a). The plan 1 is extracted (S108), and the next plan (plan 2) is verified (S108a).
FIG. 5 is a reference diagram illustrating the reduction, and S1 and S2 indicate the reduced distance. As a result of such reduction, the plan is considered appropriate if it fits within the length of the frontage and depth specified by the former.
However, if Party A falls below the permissible range (S107b), even if Plan 1 is reduced to the maximum, it will not fit within the frontage and depth length specified by Party A, and Plan 1 will be extracted as inappropriate. Not done. The other plan (plan 2) stored in the storage device (2) is verified.
In this embodiment, the length of the frontage and the depth is set as the search condition upper, but when an area is further set as the upper, for example, “total floor area 100 m ² ”, the total floor of Plan 1 is set. If the area falls within 100 m ² , the plan 1 is extracted as suitable, and if it exceeds 100 m ² , the plan 1 is not extracted as inappropriate. In this case, even if the frontage and depth do not satisfy the search condition, the plan is extracted if the area satisfies the search condition, and the plan is extracted if the frontage and depth satisfy the search condition even if the area does not satisfy the search condition. It is also possible to do.

  FIG. 7 shows the number of cases displayed (S109) on the display device (4) of the results verified for all the accumulated plans. On the screen, “staircase” and “between floors” are displayed to confirm that they are not reduced.

  Next, by clicking the “list display button”, a search result list is displayed on the display device (4) as shown in FIG. 8 (S109), and when a specific plan is clicked, a search is performed as shown in FIG. The outline is automatically reduced and displayed in accordance with the frontage and depth satisfying the conditions (S109).

  Although not shown, the search result can be arbitrarily displayed at each display stage by the output device (5) (S110).

As described above, according to the present embodiment, it is possible to search for a plan that may fit even if the frontage, depth, and area of the plan do not fit in the values set as the search conditions, and there are few narrow land plans. Even efficient search is possible.
In addition, it is possible to efficiently search from the frontage, the depth, and the area for the plan of a one-story building, a building having a basement, and a building having three or more stories as in this embodiment.

A second embodiment of the present invention will be described with reference to FIG. FIG. 9 is a reference diagram showing a screen displaying an inappropriate plan.
In the present embodiment, as a result of considering the allowable range of the entire building, the minimum frontage and depth information necessary for using the plan are displayed for a plan that is not extracted as not matching the search condition. It is about technology.

In FIG. 2, the building plan processed as an unsuitable plan in S107b is temporarily stored in the storage device (2) together with the allowable range calculated as the entire building plan. Then, by clicking the inappropriate plan display button (FIG. 7), the screen is displayed on the screen (FIG. 9).
In this embodiment, in addition to the means provided in the previous embodiment, an inappropriate plan temporary storage means, an extraction means for extracting the stored inappropriate plan, and a display means for displaying the inappropriate plan are provided.

By displaying the unsuitable plan together with the minimum allowable range according to the present embodiment, the search range is expanded, and the search result once performed without the customer re-setting the search condition instep (frontage, depth information). It can be used effectively.
In this embodiment, the length of the frontage and the depth is set as the search condition upper, but the area can be set as the upper as in the first embodiment.

A system and method for searching in consideration of the possibility of contraction of a building plan,
In addition to floor plans, it can be applied to external plan searches such as garages and planting arrangements outside the building. Further, the present invention can be applied not only to a narrow area but also to a case where a plan search is performed in consideration of a floor area ratio, a building coverage ratio, a road oblique line restriction, and the like in an area where regulations are severe.
