[0001]
[Industrial applications]
The present invention relates to a building design support device for designing a building such as a house constructed from panels serving as a skeleton, and in particular, a position or a room of a wall which determines a design of the building in the building. At the stage of deciding the layout, that is, at the stage of deciding the layout, determine the arrangement of load-bearing walls and foundations taking into account the strength required for the building, and allocating panels according to the required strength of the building and laying out the structure of the building The present invention relates to a building design support device to be determined.
[0002]
[Prior art]
In general, for a person who intends to construct a building (owner), when designing a building, it is important to determine the floor plan of each floor and the design of the building such as the shape of the roof and the positions of windows and doors. It becomes a problem.
[0003]
On the other hand, the designer who actually designs the building, when embodying the design of the building desired by the owner, considers that the strength of the building will be a predetermined value or more as an important factor You have to design things. In other words, at the design stage, the designer determines the strength and arrangement of the pillars, beams, and load-bearing walls, etc., that will be the skeleton in response to the stress applied to the building, and calculates the strength of the building to be designed by strength calculation. It is necessary to finally decide the design while confirming.
[0004]
In other words, when designing a building such as a house, it is not possible to determine solely the design of the house such as a layout, and it is necessary to always determine the layout while considering the required strength of the building. The owner who does not have the ability to decide on a design such as a floor plan.
[0005]
Therefore, in the conventional building design, the owner cannot change the layout of the room, change the position of the pillar, or change the position of the opening provided on the wall surface such as the window or the door. If the owner requests a change in the floor plan, the position of the pillar, or the position of the opening, the designer should change the position of the pillar or beam in consideration of the strength, or change the position or amount of the load-bearing wall. Needed to change.
[0006]
Also, a panel construction method is known in which floors, walls, and roofs of houses are mainly constructed from rectangular panels.
In a house made of such a panel construction method, a floor or a roof is mainly supported by a panel constituting a wall, and a load applied to the floor or a roof is supported by a panel which is allocated to the floor or a roof, and is allocated to the floor or a roof. The applied panel transmits the load to the panel allocated to the wall, so that columns and beams are not used much.
[0007]
And, in the building by the panel method, it is necessary to determine the layout in consideration of the position of the wall, that is, the arrangement of the load-bearing wall corresponding to the vertical load and the horizontal load and the support wall corresponding to the vertical load. It is necessary to consider the strength of floor panels and roof panels supported by walls and support walls.
[0008]
[Problems to be solved by the invention]
By the way, if it is possible to design each house with time and expense, the designer and the owner will spend a long time designing and designing the building, taking into account the strength and other factors. Can be done, but of course at a high cost in the design.
[0009]
Therefore, in a prefabricated house using the above-mentioned panel construction method, in general, the sales staff of the sales office and the customer who is the owner consult with each other, and consider the cost of the building, the location conditions of the building, etc. By selecting one type of building design from a plurality of types of building designs, the cost of design and structure determination has been reduced.
[0010]
Therefore, the owner selects a design of a building close to his / her favorite layout or appearance from the design of a plurality of pre-typed buildings, and selects an interior or an exterior which has been previously set as an option for the building. It was difficult to design a building that perfectly matched his taste.
[0011]
Also, in the case of prefabricated houses, if the owner freely decides the design of the building, such as the floor plan, the design and structure of the building and the design and structure are determined in consideration of the strength of the building. It took a lot of time to check the strength of the building, and it was difficult to reduce the cost of the design.
[0012]
Further, as described above, when the owner freely decides the design of the building such as the floor plan, the salesperson of the prefabricated house cannot determine the design or structure, that is, the salesperson The discussions may not be able to manage all of the home sales and may cause problems with sales activities.
[0013]
For example, in the case where the design and structure of a house is decided based on the design of the house decided by the owner, even if one estimate is made, the intention of the owner is transmitted to the designer, and the designer It is necessary to make a decision on the design and structure of the house based on it, and it takes time for the sales activities, and there is a possibility of eliminating the opportunity for selling the house.
[0014]
The present invention has been made in view of the above circumstances, and allows the owner to freely determine the design of the building such as floor plan, and based on the design of the building determined by the owner, It is an object of the present invention to provide a building design support device that can easily determine a design and structure and check strength, and can easily and quickly design a building reflecting the intention of the owner. Things.
[0015]

The above-mentioned structural model creating means is to solve the above-mentioned problem by allocating panels to floors, walls, and roofs and allocating necessary members to a preset building.
[0022]
[Action]
According to the configuration of the first aspect, for example, when the owner decides the floor plan of the building to be built based on his / her own request, the arrangement of the wall surrounding each room is input by the design input means a. Is done.
Next, the wall line creating means b creates a wall line indicating a wall supporting a building among the walls surrounding each room input by the design input means a.
[0023]
Next, the wall amount checking means c determines whether the amount of walls that can be arranged on the wall line created by the wall line creating means b is sufficient to support a building.
Next, based on the wall line created by the wall line creating means b, the structural model creating means d assigns panels to the wall, floor, and roof regions, and determines the structure of the building to be built.
[0024]
That is, in the building design support apparatus of the present invention, the owner decides a design of a building such as a floor plan without considering the strength of the building or the like.
The building design support device of the present invention recognizes, as a wall line, a portion where a wall supporting the building can be arranged from a wall surrounding the room based on the floor plan determined by the owner, and further arranges the portion on the wall line. The wall amount checking means c confirms whether the amount of the wall that can be formed can actually maintain the strength of the building.
[0025]
Therefore, when designing a building like a conventional building, the design of the building such as a floor plan and the structure of the building such as the position of the load-bearing wall are determined in parallel. The owner can decide freely to some extent without considering the strength of the building.
[0026]
Further, when the position of a wall supporting the house such as a load-bearing wall is determined, it is possible to assign a panel to each wall, and furthermore, a panel assigned to a floor area (floor panel) and a panel assigned to a roof area ( The roof panels are basically arranged so as to extend between the walls that support the house. Therefore, when the position of the walls that support the house is determined, the layout of the floor panels and the roof panels can be determined. It becomes possible.
[0027]
According to the second aspect of the present invention, in addition to the above configuration, the purlin line creating means e is basically a panel roof which is allocated to the roof based on the wall line created by the wall line creating means b. Creates a purlin line indicating the position of the side edge orthogonal to the inclination of the panel, so that the structural model creating means d easily allocates the panel and the members supporting the panel to the roof area corresponding to the purlin line. Can be opened.
[0028]
According to the third aspect of the present invention, in addition to the above configuration, the structural model creating means d has the panel allocating means f for allocating panels as described above, and has the cross-section calculating means g for performing the cross-sectional calculation. Therefore, it is possible to calculate the cross section of the floor or roof panel spanning between the wall panels supporting the building to determine whether there is any problem in strength.
[0029]
Further, according to the configuration of claim 4 in addition to the above configuration, the cross-section calculating means g may be provided at a distance between supporting members for supporting a panel or a beam-shaped member having a predetermined strength, or at one end of the supporting member. It is determined whether or not the length of the held panel or beam-like member extending from the support member is within a predetermined range.
[0030]
That is, since each panel has a predetermined strength, for example, a panel for the second floor is capable of sufficiently supporting an expected load of furniture, a person, or the like in a state where both ends are supported by a wall. If the walls are arranged so that both ends of the floor panel can be supported by the walls, the strength in the cross-sectional design of the floor can be determined to be sufficient.
[0031]
In other words, if the distance between the walls that support the house and oppose each other is shorter than the floor panel prepared in advance, the structure of the floor on the second floor as a sectional design will be sufficient.
[0032]
That is, a portion having a predetermined strength, and a panel or a beam-shaped member arranged so as to be bridged is allocated, for example, a floor or a roof, a distance between support members supporting the panel, and the panel Alternatively, by judging in correspondence with the strength of the beam-shaped member, a cross-sectional design having sufficient strength can be performed.
[0033]
Further, even when the panel or the beam-shaped member is supported by the cantilever, the panel or the beam-shaped member has a predetermined strength. The cross-sectional design can be performed by determining how much is extended.
[0034]
According to the configuration of the fifth aspect, the opening of the wall is input by the design input means a, and the wall amount checking means c arranges the bearing wall at a portion of the wall line other than the opening. If so, it will be determined whether the amount of these load-bearing walls is sufficient for the building to be built.
[0035]
In other words, the owner can specify the layout of the rooms and the positions of the openings such as windows, entrances and exits, and the passages before the structure of the house is determined. Then, it is determined whether or not the strength of the building is impaired by the opening.
If the amount of load-bearing walls that can be arranged is determined to be sufficient by the wall amount checking means c, the opening determined by the owner is directly reflected in the design and structure of the building.
[0036]
Further, according to the configuration of the sixth aspect, the structural model creating means d assigns a foundation based on the wall line created by the wall line creating means b.
That is, according to the above configuration, the wall line indicating the wall supporting the house is created by the wall line creating means b, so that a load is applied to the wall of the wall line portion from above, and Since a foundation and a base are required below the base, the arrangement of the foundation can be determined based on the wall line.
[0037]
By deciding the layout of the foundation as described above, the design and structure determination based on the position of the wall surrounding each room based on the arbitrary floor plan input by the design input means can be performed on almost all parts of the house. It will be done in.
According to the configuration of the seventh aspect, the layout position and the shape of the roof are input by the design input means a, and the structural model is created. Prior to the determination of the structure by the means, the arrangement positions of the fittings and fixtures whose arrangement positions can be determined are input, and the structural model creating means performs the layout of panels on floors, walls, and roofs, as well as the preset building Necessary for the building design, and the building design support apparatus of the present invention can determine almost all the design of the building.
The components in the “Means for Solving the Problem” and “Action” columns have been described based on the reference numerals in FIG. 1, but the present invention is not limited to the configuration shown in FIG. Absent.
[0038]
【Example】
Hereinafter, a building design support apparatus according to an embodiment of the present invention will be described with reference to the drawings.
As shown in FIG. 2, the building design support apparatus according to this embodiment includes a central processing unit and a memory such as a random access memory (RAM) and a memory such as a ROM (read only memory) serving as an internal storage device. An arithmetic processing unit (computer) 1, an auxiliary storage device 2 including a hard disk, a magneto-optical disk, and the like; a display device 3 such as a color display device including a CRT (Cathode Ray Tube) or an LCD (liquid crystal display); The basic configuration includes an input device 4 such as a keyboard, a pointing device (coordinate position input device) 5 such as a mouse, a tablet, and a digitizer, and an output device 6 such as a printer and a plotter.
[0039]
The auxiliary storage device 2 has internal codes No. of various members for constructing a house. , Graphic data, shape data, ordering product code No. And the unit prices of various members are stored as a database.
In addition, the auxiliary storage device 2 is used for inputting a design such as a floor plan, and for allocating various members based on the input design and the logic of the strength of the house including the panel of this embodiment. A program for determining the structure of the house and data necessary for processing of these programs are stored.
[0040]
The arithmetic processing unit 1 has a function of inputting a design of a house based on the program and determining a structure of the house having sufficient strength based on the input design.
[0041]
That is, for example, the arithmetic processing device 1 is configured to operate vertically based on the arrangement of the wall 12 (shown in FIG. 5) surrounding each room 11 (shown in FIG. 5) input as a design of the house based on the floor plan considered by the owner. A load-bearing wall line 22 (shown in FIG. 10) indicating a position where a load-bearing wall 23 (shown in FIG. 11) corresponding to a load and a horizontal load and a support wall 25 (shown in FIG. 11) corresponding to a vertical load can be respectively arranged. And a support wall line 24 (shown in FIG. 10).
[0042]
Further, the arithmetic processing unit 1 recognizes a portion where the load-bearing wall 23 can be arranged on the load-bearing wall line 22 created as described above, that is, a portion without the opening 36 (shown in FIG. 17), and recognizes the load-bearing wall 23. It has a function of determining whether the amount of the placeable portion is sufficient to maintain the strength of the house.
[0043]
Then, based on the walls 12 (bearing walls 23 and support walls 25) surrounding each room, the arithmetic processing device 1 allocates an area of the wall 12 where the wall panel 38 (shown in FIG. 17) is allocated, and a floor panel 44 (see FIG. 19). It has a function of recognizing the area of the floor 29 (shown in FIG. 14) to which the illustrated) is allocated and the area of the roof 28 (shown in FIG. 15) to which the roof panel 34 (shown in FIG. 16) is allocated.
[0044]
Then, the arithmetic processing unit 1 has an area where the wall panel 38 is allocated to the area of the wall 12, the area of the floor 29, and the area of the roof 28.
In addition, the arithmetic processing unit 1 includes, in addition to the wall panel 38, the floor panel 44, and the roof panel 34, members necessary for the structure of the house, for example, adjusting members and beams 35 (shown in FIG. 15) disposed on the roof 28, and the like. It has the function of allocating members.
[0045]
Further, the arithmetic processing device 1 is horizontally or diagonally arranged such as a wall panel 38, a roof panel 34, a beam 35, a magsa (not shown), and at least one end thereof is supported by the wall panel 38 or the like. It has a function of calculating a cross section (cross section design) of a member supported and arranged by the member.
The arithmetic processing device 1 has a function of outputting the structure of the house, such as the layout of panels determined as described above, as various drawings.
[0046]
Hereinafter, a method of designing a house and determining the structure of the house by the building design support apparatus of this embodiment will be described.
FIG. 3 is a drawing showing a main flow of the building design support apparatus of this embodiment.
[0047]
In the design support device, first, the design of the building (house) is determined and input (Step A1), and then, in the design check (Step A2), the arrangement of the load-bearing walls and whether the placed load-bearing walls are sufficient are checked. In the structural model creation (step A3), panels and other members are assigned to the walls 12, floor 29, roof 28, etc. of the house, and the cross-section calculation is mainly checked for floor 29 and roof 28. Then, the structure of the house determined as described above is output as various drawings (step A4).
[0048]
FIG. 4 is a flowchart for explaining the design input.
As shown in FIG. 4, in the design input, first, the input of the wall 12 is performed (step B1).
That is, based on the shape of the site on which the house is built, various conditions, and the like, the owner decides each room (space) of the house, such as each living room, living room, dining room, kitchen, bath, toilet, and stairs 18 (shown in FIG. 7). Is determined, and the layout of the wall 12 surrounding each room 11 is input.
[0049]
At this time, the user inputs the wall 12 even in a place where the wall 12 has an opening 36 such as a window, an entrance, a passage, or the like. That is, basically, the walls 12 are arranged so that the four sides of each room 11 are surrounded by the walls 12 except for the stairs 18 and the like.
In this embodiment, as shown in FIGS. 5 and 6, an input screen 13 for arranging the wall 12 surrounding the room 11 is displayed on the display device 3. (Not shown) is set, and the center line of the wall 12 is arranged along the grid line.
[0050]
This is because, when an arbitrary position on the input screen 13 is instructed to the coordinate position input device 5, the indicated position moves to the grid line closest to the arbitrary position. The center is basically arranged on a grid line.
[0051]
In FIG. 5 and FIG. 6, the grid lines are not displayed as grid lines, but only the intersections 14 of the grid lines are displayed. In FIGS. 5 and 6, two grid lines, a large grid line and a small eye line, are arranged. The intersection 3 shown in FIGS. 5 and 6 is the intersection 3 of the large grid line. Actually, small grid lines of the eyes are also arranged between the intersection points 3, and the center line of the wall 1 can be arranged along the small grid lines of the eyes.
[0052]
In the design support apparatus of this embodiment, the design is performed on a module basis, and the grid lines arranged on the input screen 13 are arranged every 1/2 or 1/4 module. It has become so. One module has a length substantially similar to a unit length generally used in a house. Each part of the house is designed according to the module, and panels are designed and manufactured in accordance with the module. It has become.
[0053]
In the input of the wall 12, the size of one room 11 (the space without the load-bearing wall 23 inside), the distance between the load-bearing walls 23, the width of the opening 36, and the like are limited. is there. In addition, for example, special design restrictions such as overhangs, blow-throughs, steps on the floor 29, and the like outside the first floor are determined.
FIG. 5 shows the arrangement of the walls 12 on the first floor, and FIG. 6 shows the arrangement of the walls 12 on the second floor. The correspondence is defined.
[0054]
These restrictions are necessary in a house composed of panels whose strength is determined in advance. However, except for the case of a special design and the correspondence between the first-floor wall 12 and the second-floor wall 12, a normal room is used. In the width of the opening 11 and the width of the opening 36, there is almost no possibility that the above restriction is violated. In addition, the restriction in the case of the special design and the correspondence between the first-floor wall 12 and the second-floor wall 12 Since the restriction itself is easy including the above, it is possible to give advice by a sales person or the like who sells the house, and it is also possible to easily check whether the design exceeds the restriction with a check sheet or the like. It has become.
[0055]
Further, in the design input program, for example, a warning is given when the limit is exceeded, or when the second floor wall 12 is arranged on the first floor wall 12, the arrangement of the second floor wall 12 is input. An auxiliary line 12a indicating the arrangement of the first-floor wall 12 is displayed on the input screen 13 (a part where the wall 12 has already been arranged is not shown in FIG. 6), and easily corresponds to the arrangement of the first-floor wall 12. By arranging the arrangement of the wall 12 on the second floor, the structural limit of the house is not exceeded during the design input.
[0056]
Therefore, the owner can determine the arrangement of the rooms with almost free ideas.
Next, design elements other than walls are input (step B2).
For example, the design elements include fittings, fixtures, porch, terrace, storage, finish of floor 29, finish of wall 12, ceiling height, ceiling with slope, bay window, balcony 20 (shown in FIG. 8), various ventilation openings And so on.
[0057]
That is, as shown in FIG. 7, general layout of windows 15, doors 16, tatami mats 17, stairs 18, system kitchens 19, balconies 20 (shown in FIG. 8), toilets (not shown), baths (not shown), and the like. Almost all components other than the room 11 of the house as shown in the figure are arranged.
Then, after the operation of step B2 is completed, as shown in FIG. 7, the members are allocated in such a manner that a floor plan of a general house can be drawn.
[0058]
Next, input and editing of a roof (step B3) are performed.
That is, the roof 28 (shown in FIG. 8) has various shapes such as a gable, a ridge, a truss house, and the like, and the inclination angle of the roof surface, the length extending from the outer wall (eave out), and the like. Differs depending on the roof 28. Therefore, it is necessary to input the conditions of the roof 28.
[0059]
When the design is input as described above, the floor plan as shown in FIG. 7 and the perspective view as shown in FIG. 8 can be obtained.
Note that the auxiliary storage device 2 of the design support device stores shape data and drawing data of various members allocated by the design input, so that the drawings shown in FIGS. 7 and 8 can be easily obtained. ing.
[0060]
Then, as shown in FIG. 7 and FIG. 8, when the design input step A1 is completed, a feeling that the design is substantially completed is given. At this stage, the panel is mainly used without using much columns and beams. The layout of the load-bearing walls 23, the calculation of the cross-section of the floor 29 and the roof 28, and the arrangement of the beams 35 which are partially necessary to support the roof 28 and the floor 29 are performed. However, the strength, which is an important factor in the design of a building, is in a state where it does not exceed the various restrictions described above.
[0061]
Therefore, in order to complete the design of the house composed of the panels, the layout of the load-bearing wall 23 and the allocation of each panel and the check of the cross-section calculation, which will be described later, are performed to determine the structure of the house in which the design is input. In addition, it is necessary to confirm that this structure has sufficient strength.
In other words, except for the above restrictions, the owner can determine his own design part that is of most interest to the owner, with little consideration of the strength.
[0062]
FIG. 9 is a flowchart for explaining the design check (step A2).
First, in the design check, it is checked whether the design data input by the design input does not exceed the above-mentioned various restrictions (construction method / structure check) (step C1).
[0063]
That is, the above-mentioned various restrictions are also checked at the time of design input, but if the above-mentioned design data exceeds the above-mentioned restrictions, it is necessary to prove that the house constructed from the panel has sufficient strength. Is difficult, so check here again.
[0064]
Then, it is determined whether or not the checked result is an error (step C2). If an error is detected, an error list is output (step C3), and the design check ends.
[0065]
In this case, it is necessary to correct the design data based on the error list. Then, if no error occurs, the load-bearing wall line 22 is automatically generated next (step C4).
As shown in FIG. 10, a bearing wall line (shown by a thick solid line) 22 indicates a portion where the bearing wall 22 is preferably installed. It is generated along the arrangement of the wall 12 where the wall 23 is preferably installed (Step C5).
[0066]
Note that the load-bearing wall 23 is not necessarily disposed on the load-bearing wall line 22. Basically, a portion without the opening 36 on the load-bearing wall line 22, that is, a portion where the blind wall is disposed is a load-bearing wall. 23.
Basically, the load-bearing wall line 22 is arranged on the outer wall portion of the house, and the interval at which the structural load-bearing wall 23 is required inside the house is predetermined, and each inner wall ( In the case where there are a plurality of inner walls at the above intervals, the load-bearing wall lines 22 are generated along some of the inner walls).
[0067]
Basically, the load-bearing wall line 22 is generated at a portion of the first floor of the house where the cloth foundation (continuous foundation) 42 is disposed, and on the second floor or higher of the house, the load-bearing wall line 22 is placed on the load-bearing wall line 22 downstairs. Is generated.
[0068]
Next, as shown in FIG. 11, the load-bearing wall 2 is automatically arranged on the load-bearing wall line 22 (step C5). At this time, the load-bearing wall 23 is arranged as a wall panel 38 having a panel width of one or more modules.
Basically, on the load-bearing wall line 22, the load-bearing walls 23 are arranged at corners, intersections, both sides of the opening 36, and the like.
[0069]
Next, after disposing the bearing wall 23, it is determined whether or not the amount of the bearing wall 23 is sufficient (step C6). Basically, the house is divided into a plurality of rectangular areas by a load-bearing wall line (a part of which is extended), and the amount (length) of the load-bearing walls 23 in each rectangular area is determined by a predetermined amount. More or less is determined.
[0070]
Note that the load-bearing wall 23 on the load-bearing wall line 22 that divides the adjacent rectangular area is distributed to one of the rectangular areas, and one load-bearing wall 23 does not belong to two rectangular areas. It has become. The load-bearing wall 23 sandwiched between the two rectangular areas and distributed to one of the rectangular areas has the other rectangular shape if the load-bearing wall 23 of the other rectangular area is smaller than the predetermined amount of the load-bearing wall 23. It can be sorted to the area side.
[0071]
With the above operation, when the amount of the load-bearing wall 23 is sufficient in all the rectangular areas, the normal state is determined. And If the load-bearing wall amount is insufficient in one or more rectangular areas, it is determined that an error has occurred (step C7), and an error list is output (step C3).
[0072]
When the error list is submitted, the design check is completed, and the design input needs to be corrected. However, as described later, in step C10, confirmation and correction can be performed. If the predetermined amount of the load-bearing wall 23 can be secured by correcting the arrangement of the load-bearing wall line 22 and the load-bearing wall 23, the design data need not be corrected.
[0073]
That is, even if an error is determined in step C7, there is a possibility that a predetermined amount of the load-bearing wall 23 can be ensured simply by changing the arrangement of the load-bearing wall line 22 and the load-bearing wall 23. It is not always necessary to change the arrangement or the arrangement of the opening of the wall 12 (that is, change the design).
[0074]
Then, as shown in FIG. 11, a support wall line 24 is automatically created (step C8). The support wall 25 is the wall 12 for responding only to the vertical load as described above, and receives the load of the floor panel 44, the roof panel 34, the beam 35, and the like disposed on the wall 12.
That is, even if the amount of the load-bearing wall 23 is equal to or more than the above-described predetermined amount, the portion necessary to structurally support the floor panel 44, the roof panel 34, and the beam 35 is not the partition wall 26 but the support wall 24. Is arranged
[0075]
When the floor panel 44 is basically supported, the floor 29 is divided into a plurality of rectangular floor areas 30, and each floor area 30 is surrounded by the load-bearing wall line 22 or the support wall line 24. Therefore, when the area of the floor 29 cannot be divided into rectangular areas by the above-described load bearing wall lines 22, the support wall lines 24 are generated so that the floor 29 can be divided into rectangular areas.
Note that, of the walls input by the design input, a wall that does not overlap with the load bearing wall line 22 or the support wall line 24 is the partition wall 26 described above, and a partition wall line (not shown) is generated.
[0076]
Next, as shown in FIG. 12, a purlin line (shown by a broken line, a solid line (thin), and a solid line (thick)) 27 is automatically created (step C9).
On the roof surface, the roof panel 34 is supported by the wall 12 such as the load-bearing wall 23 or the support wall 25. The upper end of the wall 12 such as the load-bearing wall 23 or the support wall 25 extends below the roof surface. It comes out.
[0077]
However, considering the shape of the roof surface and the cross-sectional design of the roof panel 34, the beam 35 is used because the wall 12 alone cannot necessarily support the roof panel 34.
The purlin line 27 is contoured from the outer wall to the roof area inside the outer wall in a contoured manner at predetermined intervals (the roof panel 34 and the roof panel 34 can sufficiently support snow that may be piled on the roof panel 34). Every span).
[0078]
Therefore, when there is no wall 12 supporting the roof panel 34 on the purlin line 27, the beam 35 is arranged on the purlin line 27. Also, basically, the upper and lower side edges of the roof panel 34 are arranged on the purlin line 27 as long as the roof panel 34 is not shorter than a predetermined length.
[0079]
Next, the load-bearing wall line 22, the support wall line 24, the partition wall line (not shown), the purlin line 27, and the load-bearing wall 23 automatically allocated are checked and corrected as described above (step C10). .
From the design input to the automatic creation of the purlin line 27, the operation can be performed without a designer.
[0080]
Then, in step C10, the designer checks the design input by, for example, the owner or the salesperson, and automatically generated or automatically allocated by the design support device.
[0081]
That is, the designer checks whether there is any defect in the automatically generated or automatically allocated portion, or whether there are significantly more load-bearing walls 23 and purlin lines 27 arranged than sufficient strength. , And the designers confirm the safety of the house.
[0082]
If there is a defect, the designer corrects the automatically generated portion. In step C1, the check as to whether or not the above-mentioned restriction, which is a prerequisite for the strength of the house made of panels, has been completed is completed. In step C6, the amount of the load-bearing wall has been checked. It is not necessary to correct the data input in the design.
[0083]
FIG. 13 is a flowchart illustrating the creation of a structural model.
As shown in FIG. 13, in creating a structural model, first, a section that requires a cross-section calculation and a section that does not require a section calculation are configured.
Basically, the sections requiring cross-section calculation are the floor 29, the wall 12 including the opening 36, and the roof 28.
That is, the floor panel 44 is disposed so as to be bridged between the wall panels 38, and it is necessary to support the floor 29 and the load on the floor 29 in a state of being bridged as described above. Is required.
[0084]
Also, on the roof, the roof panel 34 is disposed so as to be bridged between the wall panel 38 and the beam 35, and the load on the roof (including roofing material such as tiles and slate) 28 and the load on the roof 28 (such as snow). As described above, it is necessary to support in the state of being bridged and transmit the load to the wall panel 38 or the beam 35, so that the cross-section calculation is required.
[0085]
Further, in the wall 12 including the opening 36, a small wall panel 39 (shown in FIG. 17) or a magsa (a beam-shaped member used in place of the small wall panel 39 when the vertical width is small) is provided on the opening 36. Is disposed. The small wall panel 39 and the magsa are supported at both ends by the adjacent wall 12 and the ridge 37 (shown in FIG. 17), and at both ends by the adjacent wall 12 and the ridge 37. Therefore, it is necessary to support the load applied on the wall 12 and to transmit the load to the adjacent wall 12 and the cubic 37, and the cross-section calculation is required.
[0086]
Therefore, in the wall 12 having the floor 29, the roof 28, and the opening 36, a part necessary for calculating the cross section is created (determination of the structure) (Step D1).
First, on the floor 29 (not shown), a plurality of floor areas 30 surrounded by the bearing wall lines 22 and the support wall lines 24 are automatically set, and then the laying direction of the floor panel 44 in each floor area (arrow 31). Set automatically.
[0087]
In the first floor, a cloth foundation 42 or a base 43 is arranged below the bearing wall line 22 or the support wall line 24. In FIG. 14, the laying direction of the floor panel 44 is such that the direction of the arrow 31 coincides with the longitudinal direction of the floor panel 44.
Therefore, the foundation 42 or the base 43 that supports the floor panel is disposed on a line (consisting of the load bearing wall line and the support wall line) indicating the periphery of the floor area 30.
[0088]
On the floor 29 on the second floor or higher, the lower floor wall (including the opening) 12 is arranged below the load-bearing wall line 22 or the support wall line 24.
Therefore, the wall 12 that supports the floor panel 44 is disposed on a line (consisting of the load bearing wall line 22 and the support wall line 24) indicating the periphery of the floor area 30.
[0089]
By determining the floor area 30 and the panel laying direction as described above, the span between the members (the foundation 42 and the wall 12) that support the panel can be obtained, and the panel whose strength is determined in advance is arranged. At this time, if the span is shorter than a predetermined length, it can be confirmed that the floor 29 has sufficient strength in the calculation of the cross section.
[0090]
In the roof, as shown in FIGS. 15 and 16, the wall 12 or the beam 35 is disposed at the purlin line 27 (shown in FIG. 12) set as described above, and supports the roof panel 34. It has become.
[0091]
In the case of the floor 29, the span between the supporting members supporting the panel can be determined by determining the floor area 30 and the laying direction of the panel, and the calculation can be replaced with the cross section. Since it has a more complicated shape than the three-dimensional floor 29, the arrangement of the walls 12 and the arrangement of the beams 35 are determined, and each roof panel 34 is actually allocated.
[0092]
Then, in a state where each roof panel 34 is allocated, the cross section of the roof is calculated from the strength of each roof panel 34 and the span between the supporting members (walls 12 and beams 35) that support each roof panel 34. It is determined whether or not it has sufficient strength.
[0093]
Next, as shown in FIG. 17, in the portion of the wall 12 having the opening 36, a wall panel 38 adjacent to the opening 13, a small wall 39 or a magsa (not shown) arranged above the opening 36, A waist wall panel 40 or a handrail wall panel (not shown) or a magsa (not shown) disposed below the portion 36, such as a small wall panel 39 on the opening 36 or a ridge 37 for reinforcing both ends of the magsa. By allocating, the cross section of the small wall 39 or the magsa is calculated.
[0094]
Basically, if the span of the small wall 39 or the magsa is within a predetermined length, it can be determined that it has sufficient strength.
After the members required for the cross-section calculation have been allocated to the floor 29, the roof 22, and the opening 36 of the wall 12 as described above, the types of the panels and magsa allocated as described above, The cross section is calculated by determining the distance between the support members (mainly, the wall 12 and the beam 35) supporting the magsa in correspondence (step D2).
[0095]
Then, in the cross-section calculation, it is determined whether or not the panel and the magsa are allocated with sufficient strength. If the determination is negative (error) (step D3), an error list is output (step D4). ), There is a point where there is a problem in strength.
[0096]
If the cross section calculation is normal, the setting of the floor area 30 and the determination of the laying direction of the floor panel 44 in each floor area 30 and the beam 35 Then, it is determined whether or not the designer has confirmed the layout of the roof panel 34 and the layout of members such as panels in the opening 36 of the wall 12 (step D5).
[0097]
Then, as described above, when the error list is output and when the designer has not confirmed, the section for calculating the cross-section is confirmed and corrected (step D6).
In other words, the designer checks the automatic creation of the section for calculating the cross section.
[0098]
Then, when the error list is output, the correction of the floor area 30, the correction of the panel laying direction, the correction of the allocation of the beams 35 of the roof 28, the correction of the roof panel 34 are performed for the problematic portions described in the error list. And the layout of the wall panel 38 around the opening 36 of the wall 12 is corrected, and the designer also checks the case where the error list is not output or other than the part indicated by the error list. Will do.
Then, when the designer determines that the correction is necessary in consideration of the strength problem and other factors such as the construction efficiency and the cost, the correction is performed.
[0099]
Then, after confirming and correcting the section for calculating the cross section, automatic processing of the cross section calculation is performed again (step D2), there is no error (step D3), and if the confirmation by the designer has been completed once (step D5), A structure model is created (step D7).
[0100]
In creating the structural model, the layout of the foundation 42 is determined, the floor panel 44 is allocated to the floor 29 in which the floor area 30 and the panel laying direction are determined, and the load-bearing wall and the wall including the opening that have been determined are determined. Assignment of panels and other members, assignment of other members to the roof to which beams and roof panels are assigned, and the like are performed.
[0101]
FIG. 18 shows the input screen 13 on which the base 42 is allocated.
As described above, the arrangement of the foundation 42 is determined based on the load-bearing wall line 22 and the support wall line 24 on the first floor. That is, the cloth foundation 42 is arranged along the load bearing wall line 22, and an independent foundation or a bundle foundation that supports the base 43 by arranging the floor panel 44 is arranged.
[0102]
FIG. 19 shows the input screen 13 on which the floor panels 44 are allocated. Then, on the floor 29, the floor panels 44 are arranged on the respective floor areas 30 along the laying direction of the floor panels 44. Basically, the floor area 30 and the laying direction are determined, and the length of the floor panel 44 is determined. Is determined, the floor panel 44 having the above length is searched from the member database and sequentially allocated.
In addition to the floor panel 44, necessary members are also allocated to the floor 29, such as the semi-base 45.
[0103]
FIG. 20 shows the input screen 13 on which the wall panels 47 are allocated.
Since the wall panel 47 is allocated around the load-bearing wall 23 and the opening 36 on the wall 12, the wall panel 47 is allocated to other portions.
In addition to the wall panel 47, necessary members are allocated to the wall 12 such as the cubic 37.
[0104]
In the roof 28 to which the beams 35 and the roof panels 34 are allocated, members other than the beams 35 and the roof panels 34 are allocated.
That is, so-called curtains, gables, blindfolds, eaves, ceilings, and the like, other than the panels that were not allocated at the stage of design input, such as the layout of the panels such as the roof panel 28, the wall panel 47, and the floor panel 44. Members such as a finishing base material, a floor finishing material, a decorative frame, a fitting, an anchor bolt, and a body bolt are allocated.
These members are members set in advance, and the respective installation conditions are stored as a program, and are allocated in the same manner as the panel.
As described above, in a house made of panels, all structurally necessary members are automatically allocated.
[0105]
Next, the structure model is checked and corrected (step D8), that is, the designer checks the automatically assigned members, and corrects any problems. Note that the confirmation and correction of the structural model are performed for the cross-section calculation part and all parts other than the cross-section calculation part.
[0106]
In a house whose structure has been determined as described above, a drawing is automatically created and output by drawing data creation.
FIG. 21 is a flowchart for explaining the drawing data creation.
The plan view of the foundation 42, the floor 29, the wall 12, the roof 28, and the like are displayed on the display screen as shown in FIGS. 15 to 20. It is created by searching for shape data and figure data of each member from the member database stored in the device 2 and creating figure data based on the searched shape data or combining the figure data.
[0107]
The figure data is also created using the shape data and the figure data stored in the auxiliary storage device 2 to create the figure data to be output to a printer or a plotter.
The drawing to be output is determined in advance, and a layout drawing of each member to the foundation 42, the floor 29, the wall 12, the roof 28, and the like can be output.
[0108]
First, it is determined whether to output all of the predetermined drawings as described above or to select and output a part of the drawings (step E1). When selecting and outputting a part, a drawing is selected (step E2).
Then, the selected drawing or all the drawings are created (step E3).
That is, figure data is created and output from the output device 6.
[0109]
As described above, the building design support apparatus of this embodiment is designed so that a person other than a designer such as a client or a salesperson negotiating with the client can determine a house constructed by a panel whose strength is determined in advance. Among the design restrictions, other than the above-mentioned restrictions, the design of the house is determined without considering the strength.
[0110]
That is, as in the past, first, the designer first determined the strength of the house, that is, the structure of the house, and determined the design of the house. The design of the house can be decided without considering it.
[0111]
Then, at the stage when the design of the house is determined, the design support apparatus performs panel operations on the floor 29, the wall 12, and the roof 28 based on the rules of the structure of the house including the panels and the design determined as described above. And other members are assigned, and the strength is checked.
[0112]
That is, in the conventional house design, while the design of the house and the structure of the house were proceeding almost simultaneously while affecting each other, the design support device of this embodiment The design is to be decided (if the strength check later becomes inappropriate, the decided design of the house may be modified).
[0113]
Therefore, the owner or the sales person can quickly determine the design in accordance with his own preference or customer's preference without relying on the designer.
In this embodiment, the house is constructed from panels, a part of the wall panel 38 allocated to the wall 12 is a load-bearing wall 23, and the floor 29 and the roof 28 are also allocated. Because the panel supports the load on the floor or roof, if the strength of the panel is set in advance, the load-bearing wall 23 is appropriately dispersed in the house and the load-bearing wall 23 is arranged. If the members supporting the panels allocated to the roof are arranged at intervals equal to or less than a predetermined length, there is no possibility that a problem will occur in the house, so the design is determined relatively freely as described above. be able to.
[0114]
In other words, there is a problem with the strength of the house when arranging a living room such as four and a half mats, six tatami mats, eight tatami mats, a relatively large living and dining room, or a relatively small bathroom or washroom with a relatively small area. Since the strength of each panel is set so as not to be affected, when deciding a general design of a house, it is not so much tied to the strength of the house.
[0115]
Therefore, it is possible to create a house design support device that designs a house design first as described above, instead of a normal house design.
As described above, the owner, the sales person, and the like can relatively freely determine the design of the house regardless of the designer. In addition, in the construction of a house that requires a large amount of money, the owner is relatively free to decide the design of the house, so the satisfaction of having designed the house by the owner and the building of the house as he or she wanted. You can give a sense of satisfaction.
[0116]
In addition, the sales representative can determine the design of the house together with the owner without having to arrange a structural meeting with the designer, etc., and can determine the design of the house based on the intention of the owner, In addition, since the decided design can be posted immediately to the owner, spending time with the designer and examining the structure by the designer to prevent missing out on the sale of the house Can be.
[0117]
As described above, in the design support apparatus of this embodiment, the structure of the house is determined automatically and the strength is checked based on the determined design of the house.
Therefore, basically, the structure of the house is determined by the owner's decision on the design of the house.
[0118]
In this case, it is checked whether the design of the house is determined within the predetermined limits, and the strength of the load-bearing wall and the cross-section calculation are checked. If there is a problem with the design itself, it is necessary to modify the design of the house.
If there is a problem with the automatically determined structure of the house (particularly the arrangement of the load-bearing walls and the section for calculating the cross section), it is necessary to have the designer correct this.
[0119]
In addition, in the design support device of this embodiment, not only an automatic check by the design support device but also a confirmation work by a designer is performed in deciding a section to calculate a section of a house and other structures. The structure of the house can be modified at the discretion of the elderly.
[0120]
Therefore, the design of the house is determined by the owner or a salesperson, and the structure of the house is automatically determined by the design support device of this embodiment based on the design of the house. In addition to checking the situation and correcting any problems, the structure of the house is determined by the designer, and the designer can take responsibility for the problem regarding the strength of the house.
[0121]
In the design support device of this embodiment, members related to the design of the house are selected and input at the stage of design input, and members related to the structure of the house are determined at the stage of creating a structural model by the design support device. Therefore, when a member to be used for a substantially house is determined and the processing by the design support apparatus of this embodiment is completed, an estimate of the house can be calculated based on the determined member.
[0122]
Therefore, after the design of the house is input by the owner or sales representative, the estimate can be calculated by determining the structure and checking the strength by automatic processing of the design support device and the final check by the designer. As described above, there is no need for the designer and the owner or sales person to balance the housing structure with the housing design, and the housing structure can be determined in a short period of time. Opportunities can be prevented from being missed, and costs for designing a house can be reduced.
[0123]
When the designer views the design support device, the owner or sales person inputs the design of the house, and the design support device determines the structure of the house. Alternatively, it can be determined that all the intentions of the salesperson are reflected, and there may be misunderstandings or poorly communicated parts between the owner or salesperson and the designer due to housing design problems. In addition, since the structure of the house is also created by the design support device, the designer basically only needs to judge whether the house created up to the structural model has no problem in strength, and the design work is performed. Can be largely labor-saving.
[0124]
In the above-described embodiment, when creating the structural model, the cross-section calculation part and the other parts are processed separately. However, it is not always necessary to separate the cross-section calculation part from the other parts. May be determined before calculating the cross section.
[0125]
That is, according to the present invention, it is possible to construct a house having no problem in strength by using a panel having a preset strength and allocating the panel within a preset limit. In the panel construction method, first, after deciding the design of a house, the present invention relates to a building design support device that can design a house by creating a structural model of the house and checking the strength of the house. By making it possible to determine only the design of the house before considering the structure and strength of the house, the intention of the owner can be easily incorporated, and the cost of designing the house has been greatly reduced. However, the method of creating the structural model and the method of calculating the cross section are not limited to the above embodiment.
[0126]
【The invention's effect】
According to the configuration of the first aspect, after the layout of the walls surrounding each room is input by the design input means, the wall line creating means sets the wall of each of the rooms input by the design input means. A wall line supporting the building is created, and the amount of wall that can be arranged on the wall line created by the wall line creating unit is sufficient to support the building. Then, the structural model creating means assigns panels to the wall, floor, and roof regions based on the wall line created by the wall line creating means, and determines the structure of the building to be built. It has become.
[0127]
Therefore, when designing a building like a conventional building, the design of the building such as floor plan and the structure of the building such as the position of the load-bearing wall Unlike when you decide in parallel In determining the design of a building, the owner can freely decide to some extent without considering the strength of the building. That is, it is possible to easily design a building reflecting the intention of the owner, and it is possible to greatly reduce the design cost in designing the building according to the order of the owner.
[0128]
Further, according to the building design support apparatus of the second aspect, the purlin line creating means is orthogonal to the inclination of the roof of the panel allocated to the roof based on the wall line created by the wall line creating means. Since the purlin line indicating the position of the side edge is generated, the structural model generating means can easily allocate the panel and the member supporting the panel to the roof area corresponding to the purlin line.
[0129]
Further, according to the building design support apparatus of the third aspect, the structural model creating means includes the panel allocating means for allocating the panels as described above and the cross-section calculating means for performing the cross-sectional calculation. It is possible to calculate the cross-section of the floor and roof panels spanning between the wall panels supporting the building to determine if there is any problem in terms of strength.
[0130]
Further, according to the configuration of the fourth aspect, the cross-section calculating means may be a space between supporting members supporting a panel or a beam-shaped member having a predetermined strength, or the cross-section calculating means may be cantilevered by the supporting member. It is determined whether or not the length of the panel or the beam-like member extending from the support member is within a predetermined range, so that the cross-section can be easily calculated.
[0131]
According to the configuration of the fifth aspect, the opening of the wall is input by the design input means, and the wall amount checking means can place a bearing wall at a portion of the wall line other than the opening. In this case, it is determined whether the amount of the load-bearing walls that can be arranged is sufficient for the building to be constructed, and the owner can freely set the position of the opening.
If the amount of load-bearing walls that can be arranged is determined to be sufficient by the wall amount checking means, the opening determined by the owner is directly reflected in the design and structure of the building.
[0132]
Further, according to the configuration of the sixth aspect, since the structural model creating means assigns the foundation based on the wall line created by the wall line creating means, it is easy to design the house from the foundation to the roof. It can be carried out.
