[Industrial application fields]
The present invention relates to a design support apparatus for designing a house whose walls are made of wall panels.
[0002]
[Prior art]
In recent years, a CAD (computer aided design) system as a design support device has come to be used in housing design.
In the conventional CAD system for house design, the house design can be assisted under the instruction of the operator, and labor saving of the house design can be achieved. In particular, the designed house can be output as various drawings, and labor can be greatly saved in the production of drawings.
[0003]
[Problems to be solved by the invention]
By the way, in the design of a house, it is necessary to ensure the strength of the housings such as columns, beams and bearing walls in order to maintain the strength of the housing, and it is necessary to set the strength and arrangement of these housings.
In some houses, for example, a floor, a wall, a roof, and the like are constructed by a panel construction method including a panel such as a floor panel, a wall panel, and a roof panel.
[0004]
In the panel method, pillars and beams are not used so much, and the strength of the house is mainly maintained by the panels.
Therefore, when designing a house composed of the above panel method, it is necessary to determine the arrangement of walls and the like so as to maintain the strength of the house, and it is necessary to allocate wall panels to the arranged walls.
[0005]
However, the conventional general CAD system for residential use does not necessarily correspond to the panel method, and does not always have a panel allocation function.
In addition, even if panels can be assigned on a CAD system, the highest strength obtained from a combination of wall panels having a predetermined strength can be obtained by simply assigning a wall panel of a predetermined shape to a designed wall. It was not always obtained.
[0006]
In addition, simply assigning a wall panel of a predetermined shape to the wall may cause problems in terms of workability.In the worst case, if the wall panel assignment is not changed at the construction site, There is a possibility that it cannot actually be constructed.
[0007]
The present invention has been made in view of the above circumstances, and when designing a house constructed by a panel construction method, before allocating a wall panel to a wall, the area of the wall is in an optimum state for allocating the wall panel. An object of the present invention is to provide a design support apparatus that can be set as described above.
[0008]
[Means for Solving the Problems]
The design support apparatus according to claim 1 of the present invention is a design support apparatus for designing a building whose walls are composed of wall panels, and each wall of the building is installed as shown in FIG. The layout of the load bearing wall line, the support wall line or the partition wall line indicating the position to be fixed, the arrangement of the regulation part that regulates the height of the wall such as the floor or the roof that causes the contact in the upper part of the wall, and the shape of the regulation part. From the stored design data storage means a and the required strength of the building, it is necessary to support the restriction part in the arrangement of the load bearing wall line, the support wall line or the partition wall line stored in the design data storage means a. Means for defining a certain load-bearing wall line and support wall line and a partition wall line that does not support the restriction part; an arrangement of the load-bearing wall line, the support wall line or the partition wall line stored in the design data storage means a; Based on the location of the restriction parts There are, was the bearing wall line, that is formed by and a directly regulating portion retrieval means b for obtaining the restriction sites that are located directly above the supporting wall lines or partition wall lines as means for solving the above-described problem.
[0009]
Further, the shape of the restriction part arranged immediately above the bearing wall line, the support wall line, or the partition wall line searched by the above-mentioned restriction part search means b is extracted from the design data storage means a, and the restriction part is supported. In the case of the load-bearing wall line and the supporting wall line , which are the types of wall lines that need to be obtained, the height to the restriction part immediately above is determined, and the height is used as the wall height to generate a wall region, In the case of a partition wall line , which is a type of wall line that does not support the restriction part, it is provided with wall area generation means c that generates a wall area having a predetermined height set in advance. As a means.
[0010]
[Action]
According to the structure of the said Claim 1, the arrangement | positioning of the load-bearing wall line, the support wall line, or the partition wall line memorize | stored in the said design data storage means a is a kind of wall line which needs to support a control part. The type of each wall line obtained by the means for defining a certain load-bearing wall line and support wall line and a partition wall line , which is a type of wall line that does not support the restriction site, is stored from the required strength of the building. The restriction part search means b directly above obtains the restriction part arranged immediately above the wall lines based on the arrangement of the wall lines and the arrangement of the restriction parts stored in the design data storage means a. That is, a floor, a roof, or the like that causes a contact with the upper part of the wall arranged on each wall line is obtained.
Then, the wall region generation means c obtains the shape of the restriction part immediately above the load-bearing wall line, the support wall line or the partition wall line from the design data storage means a, and based on the shape of the restriction part, the load-bearing wall In the line and the supporting wall line , the height from the floor to the restriction part directly above is obtained, and the wall area is generated by using the height as the wall height , and the partition wall line has a predetermined height set in advance. Generate the wall area .
[0011]
Therefore, by designing the structure of the panel construction method by clarifying the structure of the wall according to the types of wall lines such as bearing wall lines, support wall lines, and partition wall lines , it is necessary to maintain the strength of the building. It is possible to prevent the occurrence of strength problems when actually constructing the wall.
Further, it is possible to automatically generate a wall area necessary for allocating the wall panel to the wall, and to easily allocate the wall panel.
The wall region generation means c determines whether to extend the wall region upward to the restriction site or to extend the wall region upward to a predetermined height based on the type of wall. It will be.
[0012]
In other words, in the case of a wall that maintains the strength of a house as a housing, the height of the wall needs to reach the lower end of the upper structure in order to support the upper structure. In the case of a non-supporting wall, the height of the wall does not need to reach the lower end of the superstructure, so even if the height of the wall is a preset height, for example, the height to the ceiling surface, There is no problem.
In the above-mentioned sections “Means for Solving the Problems” and “Operation”, the description has been made with reference to the reference numerals in FIG. 1, but the present invention is not limited to FIG.
[0013]
【Example】
Hereinafter, an embodiment of the present invention will be described with reference to the drawings.
The design support apparatus of this embodiment is used for designing a house in which floors, walls, roofs, and the like are constructed from panels (schematic diagrams of floor panels and wall panels are shown in the drawings).
The panel is formed by, for example, assembling wooden core members into a rectangular frame shape to form a frame body, and attaching a face material to at least one surface of the frame body.
[0014]
In addition, the design support device includes a design input function for inputting a layout of a house, arrangement of various fittings and various finishing members (design of a house), and a panel on a floor, wall, roof, etc. in the design input . In addition to the arrangement, other structural members and members attached to the panel and the panel are arranged, and the structure determination function for checking the required strength of the house and the members assigned in the design input and structure determination And an integration function for obtaining an estimate of the house to be designed.
[0015]
As shown in FIG. 2, the design support apparatus of the present embodiment has a system configuration as a so-called general computer system as a CAD system, and includes a CPU (central processing unit), RAM (random access) not shown. memory), ROM (read only memory), etc., an arithmetic processing unit (computer main body) 1, a storage device 2 consisting of a hard disk drive, etc., and an input device 3 consisting of a keyboard, mouse, tablet, digitizer and other pointing devices And a display device 4 composed of a display such as a CRT display and a hard copy output device 5 composed of a printer, a plotter or the like.
[0016]
The storage device 2 stores various programs used in the design support apparatus and various data used in the programs.
The above-mentioned various programs are basically a well-known CAD system except for the portion related to the present invention, and are for designing a house on a design support apparatus.
The various data is data of various members assigned to the house when the house is designed on the design support device. For example, various data such as various member shapes and prices are stored. .
[0017]
Further, the storage device 2 stores design data generated by design operations performed at each stage such as design input , structure determination , and integration.
Further, in this embodiment, when the floor plan is determined in the design input function, the room area of the house to be designed (living room, dining room, kitchen, toilet, bath, living room, storage, etc., basically surrounded by walls. with regions include) is input to the outer peripheral line of the room is the wall line 10 (shown in FIG. 3), also on the wall line 10, windows, doorways, openings such as the passage (shown The arrangement of the wall line 10 including the opening is stored as the design data file 2a.
[0018]
Further, in this embodiment, as shown in FIG. 3, in the structure determination function, the wall line 10 is classified into a load-bearing wall line 10a, a support wall line 10b, a partition wall line 10c, and the like according to preset logic. In the arrangement of the wall lines 10 in the design data file 2a, the types of the openings and the wall lines 10 are stored.
[0019]
Here, the kind of the said wall line 10 is demonstrated.
The wall line 10 is classified into a load-bearing wall line 10a, a support wall line 10b, a partition wall line 10c, and the like based on the structural classification of the walls arranged on the wall line 10.
On the bearing wall 10a, a bearing wall that basically supports a horizontal load and a vertical load is disposed. Note that the bearing walls are not arranged at all portions on the bearing wall line 10a. For example, when an opening such as a window, an entrance, a passage, or the like is disposed on the bearing wall 10a, the opening portion is not a bearing wall.
[0020]
A support wall that basically supports a vertical load is disposed on the support wall line 10b. Further, as in the case of the load bearing wall wire 10a, the support walls are not necessarily arranged at all the portions on the support wall wire 10b.
A partition wall that does not particularly support a load is disposed on the partition wall line 10c.
Note that some walls are arranged not diagonally but diagonally, and for such diagonal walls, the layout data of the wall line 10 in the design data file 2a indicates that the wall is diagonal. Data and data such as wall inclination are registered.
[0021]
In addition, the storage device 2 stores data on houses designed as described above. The floor arrangement, roof arrangement, and roof balcony arrangement of the second and higher floors have the height of the wall. The arrangement of the restriction parts to be regulated is set, and the arrangement data of the restriction parts and the shape of the restriction parts are stored in the design data file 2a.
[0022]
That is, the wall on the load-bearing wall line 10a or the support wall line 10b is a wall that supports a floor or a roof, and the upper end of the wall needs to be joined to the floor or the roof. The height is regulated by the floor and roof.
In this embodiment, since the floor and the roof are also constituted by the floor panel and the roof panel, the floor panel and the roof panel respectively arranged on the floor and the roof are used as the layout and shape data of the restriction part. Is stored as data on the lower surface of the.
[0023]
The arithmetic processing unit 1 has a function as a well-known CAD system, and in this embodiment, recognizes the type of each wall line 10 in the arrangement data of the wall lines 10 stored in the storage device 2. It is like that.
That is, the arithmetic processing device 1 reads the types of the wall lines 10 from the data of the arrangement of the wall lines 10 stored in the storage device 2.
And when the wall line 10 is the wall line 10 which does not support an upper structure like a partition wall line, the function which produces | generates from the floor to the preset height below the lower end of an upper structure as a wall area | region Have
[0024]
Further, in the case where the wall line 10 is a wall line 10 that supports an upper structure, such as a load-bearing wall line 10a or a support wall line 10b, the arithmetic processing unit 1 next has an upper structure immediately above each wall line 10. A function (restriction part) is searched from the arrangement data of the restriction part stored in the storage device 2 and has a function of recognizing the restriction part immediately above each wall line 10.
Then, the shape of the restriction part immediately above each wall line 10 is searched from the shape data of the restriction part 10 stored in the storage device 1.
And the arithmetic processing unit 1 has a function which produces | generates the surface from the floor containing the said wall line 10 to the lower end of the said restriction | limiting part as a wall area | region.
[0025]
Next, a method for generating a wall region in the design support apparatus having the above-described configuration will be described with reference to a flowchart shown in FIG.
First, for example, the arrangement of the wall lines 10 as shown in FIG. 3 is read from the design data file 2a of the storage device 2 (step S1).
Next, it is determined whether or not the data indicating that the wall is diagonal is included in the read arrangement data of one wall line 10 (step S2).
[0026]
Then, if there is data indicating that it is diagonal, a diagonal wall region is generated based on the diagonal wall data registered in the design data file 2a (step S3).
The wall line 10 is in a state of being divided at the intersection of the wall lines 10, and the one wall line 10 indicates the wall line 10 divided at the intersection.
In step S2, if there is no data indicating that the wall is slanted in the data of the wall line 10, the type of the wall line 10 is a partition wall line (all wall lines that do not support the upper structure). Is included) (step S4).
[0027]
And when the kind of the wall line 10 is the partition wall line 10c, as shown in FIG. 5, let the preset height be the wall height L1, and the said wall line 10 (in FIG. A position from the floor to a preset height is generated as a wall area 12a of the partition wall along the broken wall line position 11) (step S5).
In FIG. 5, reference numeral 13 indicates a floor area, and reference numeral 14 indicates a lower surface of the roof area 15 (shown in FIG. 8).
[0028]
In addition, the shape of the restriction part immediately above the wall line 10 is read, and when the height of the lower end of the restriction part is lower than the preset height L1, the height of the wall region 12a is corrected, The wall region 12a is generated with the height of the lower end of the restriction portion as the wall height.
In addition, when the restriction part is a roof, a connecting beam 16 (illustrated in FIG. 6), which will be described later, may be disposed on the wall. In this case, the height of the wall is set to the lower end of the restriction part. The wall region 12a is generated as far as the lower end of the combined beam 16 in a state where the combined beam 16 is arranged.
[0029]
In step S4, when the type of the wall line 10 is not the partition wall line 10c, that is, when the type of the wall line 10 is the support wall line 10b or the load-bearing wall line 10a, next, The arrangement of the restriction part immediately above is read (step S6), and the restriction part on the wall line 10 is searched (step S7).
Then, it is determined whether or not the restriction site directly above the wall line 10 is a roof (step S8).
[0030]
Then, when the restriction site immediately above the wall line 10 is a roof, it is next determined whether or not the wall line is orthogonal to the inclination of the roof (step S9).
That is, when a wall is arranged on the wall line 10, it is determined whether the upper side of the wall is horizontal and perpendicular to the roof inclination or is inclined along the roof inclination.
And when the said wall line 10 is orthogonal to the inclination of a roof, as shown in FIG.6 and FIG.7, although the upper side of a wall produces | generates the rectangular-shaped wall area | region 12b, In this case, as shown in FIG. 6, it is necessary to arrange a connecting girder 16 whose upper surface is inclined so as to absorb the inclination of the roof at the upper end of the wall.
[0031]
Therefore, first, the height of the lower surface 14 of the roof immediately above the wall line 10 is obtained from the shape of the restriction portion of the design data file 2a of the storage device 2, and the height of the connecting beam 16 is subtracted from the height. Thus, the height L2 of the wall region 12b is set.
In this embodiment, the height of the roof lower surface 14 is not the height from the upper surface of the floor region 13 but the height from the ground 17, so the height L2 of the wall region 12b is actually the roof. The height of the connecting beam 16 and the height L3 from the ground 17 to the upper surface of the floor region 13 are subtracted from the height of the lower surface 14 .
Then, as shown in FIGS. 6 and 7, a wall region 12b from the upper surface of the floor region 13 to the height L2 is generated along the wall line 10 (step S10).
In FIG. 7, the wall region 12b is shown as a plane, but at this stage, the wall region 12b may be thick or flat.
[0032]
In step S9, if the wall line 10 is not orthogonal to the slope of the roof, the lower surface of the roof region 15 immediately above the wall line 10 from the shape of the restriction portion of the design data file 2a of the storage device 2 Find the height of.
At this time, the height of the lower surface 14 of the roof region 15 is slanted along the slope of the roof as shown in FIG.
Then, a height from the floor to the lower surface 14 of the roof region 15 along the wall line 10 is generated as a wall region 12c (step S11).
[0033]
As shown in FIG. 9, the wall region 12c at this time does not have a rectangular shape, but has a shape in which the upper side is inclined.
And in said step S8, when the control part immediately above the said wall line 10 is not a roof, it is next determined whether the said control part is a floor (step S12).
And when the said restriction | limiting part is a floor, as shown in FIG. 10, the lower surface of the upper floor area | region 13a from the floor immediately above the said wall line 10 from the shape of the restriction | limiting part of the design data file 2a of the said memory | storage device 2 Find the height up to 18.
[0034]
The height L4 of the wall region 12d to be generated is the height L3 from the height L5 from the ground 17 to the upper surface of the upper floor region 13a to the upper surface of the lower floor region 13 and the height L3 of the upper floor region 13a. The thickness is subtracted.
Then, a wall region 12d from the floor to the height L4 is generated along the wall line 10 (step S13).
[0035]
Note that the thickness of the floor panel arranged in the upper floor area 13a may vary depending on the strength problem. When the thickness is increased, the floor panel is lowered from the upper surface of the upper floor area 13a as shown in FIG. Therefore, the height L4 of the wall region 12d differs depending on the type of the floor panel to be arranged.
Further, in the thick floor panel, as shown in the floor region 13a of FIG. 11, the portion that is hooked to the outer wall may be cut out to be a cutout portion 19, so that depending on the type of the wall panel Depending on whether the wall is an inner wall or an outer wall, the height L4 of the wall region 12d may be changed.
[0036]
Next, when the restriction part is not a floor in step S12, it is next determined whether or not the restriction part is the roof balcony 20 (step S14).
And when the said restriction | limiting part is the roof balcony 20, as shown in FIG. 12, it is fundamental to the lower surface of the floor panel (roof balcony floor area | region 13c) which forms the roof balcony 20 like the case of the said floor. A wall region 12e is generated (step S15).
[0037]
That is, as shown in FIG. 13, the height L7 of the wall region 12e to be generated is the same as in the case where the restriction part is the floor, and the lower floor from the height L8 from the ground 17 to the upper surface of the roof balcony floor region 13c. This is obtained by subtracting the height L3 to the upper surface of the region 13 and the thickness L9 of the roof balcony floor region 13c.
14, 15, and 16, the roof balcony 20 also has a difference in the thickness of the floor panel forming the roof balcony floor region 13 c as in the floor, and a notch is formed in the outer wall latching portion of the floor panel. The part 19 may be formed, and the height of the floor lower surface varies depending on the type of the floor panel.
In the roof balcony floor region 13c, as shown in FIG. 15, the cutout portion 19 may be formed on the inner wall side, and the height of the wall region 12e may be affected by the layout of the floor panel. There is also.
[0038]
And in said step S14, when a control part is not the roof balcony 20, an error process is performed (step S16).
Then, it is determined whether or not the wall line 10 that has not been subjected to the generation processing of the wall regions 12a to 12e remains (step S17). If the wall line 10 remains, the process returns to step S2 to return all the wall lines. The wall regions 12a to 12e are repeatedly generated until the wall regions 12a to 12e are generated.
And the wall panel is allocated to the produced | generated wall area | regions 12a-12e, and the structure of a wall will be determined.
[0039]
As described above, according to the design support apparatus of this embodiment, the arrangement data of the wall line 10 indicating the arrangement of the wall, the data of the type of the wall line 10 indicating the type of the wall, and the data on the wall line 10 The height of the wall is obtained from the data of the arrangement of the restriction part that restricts the upper end of the wall and the shape data of the restriction part, and the wall panel should be assigned based on the height of the wall Since the regions 12a to 12e are generated, when the wall panel is allocated, it is only necessary to allocate the wall panel so that the wall region is entirely filled with the wall panel.
[0040]
In other words, at the stage of allocating the wall panel, it is not necessary to consider the structure of the floor and the roof supported by the wall, and the wall panel having a predetermined shape is simply arranged in the area where the shape is determined. Panel assignment can be performed, and wall panel assignment processing can be facilitated.
At this time, the partition wall that is not significantly affected by the superstructure and the other walls are distinguished from each other and processed, thereby facilitating the generation of the wall region.
In the case of a load bearing wall or support wall that is affected by the upper structure, the upper shape of the wall region can be easily determined by extracting only the shape of the portion directly above the wall line.
[0041]
【The invention's effect】
As described above in detail, according to the design support apparatus according to claim 1 of the present invention, the design support apparatus is for designing a building whose wall is composed of a wall panel. In the data storage means, the arrangement of the load-bearing wall line, the support wall line or the partition wall line indicating the arrangement of the wall, the arrangement of the restriction part for regulating the height of the wall such as the floor or the roof, and the shape of the restriction part are stored. The arrangement of the load-bearing wall line, the support wall line, or the partition wall line is a load-bearing wall line that is a kind of wall line that needs to support the restriction part, and a kind of wall line that does not support the restriction part. The means for defining a partition wall line stores the type of each wall line obtained from the required strength of the building, and the above-mentioned restriction part search means is used for the load-bearing wall line, support wall line, or partition wall line . Search for the restriction part placed directly above and But with determining the height of the retrieved restriction regions will produce a wall region based on the height-.
[0042]
Therefore, by designing the structure of the panel construction method by clarifying the structure of the wall according to the types of wall lines such as bearing wall lines, support wall lines, and partition wall lines, it is necessary to maintain the strength of the building. It is possible to prevent the occurrence of strength problems when actually constructing the wall.
Moreover, when allocating the wall panel, it is not necessary to consider the joint between the wall and the floor or the roof, and the wall panel is simply filled with the wall area generated as described above. It is only necessary to arrange the wall, and labor saving of the wall panel assignment work can be achieved.
In addition, as described above, since the height of the wall area is obtained from the shape data of the restriction part as described above, when the wall is constructed with an actual wall panel, the wall panel cannot be installed. Problems can be prevented from occurring.
[0043]
In addition, the wall region generation means, as described above, is the height from the floor to the restriction part only when the type of the wall line supports the restriction part, that is, in the case of a load-bearing wall line and a support wall line. The wall region is generated based on the height, and if the type of the wall line does not support the restriction part, the wall region of a predetermined height is obtained without obtaining the height of the restriction part. By producing | generating, the wall area | region for partition walls can be produced | generated easily.
