DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a wall panel allocating apparatus for laying out panels constituting a wall of a prefabricated house by a panel construction method, and more particularly to a hut having a sloped side along a roof slope. The present invention relates to an allocating apparatus for allocating a roof panel arranged in a portion.

[0002]

2. Description of the Related Art As one method of constructing a prefabricated house, a panel construction method in which floors, walls, roofs, and the like are constituted by panels is known. In this method, a floor panel, a wall panel, a roof panel, and the like, which are manufactured by pasting a face material on at least one surface of a frame body that has a core material framed in a factory or the like in advance, are assembled at a building site. Build houses by going.

FIG. 26 shows how a wall and a roof in such a house fit together. As shown in FIG. 1, the wall 1 has an upper side portion capable of abutting against the back surface of the roof 2, and has a rectangular wall panel P and a substantially triangular or trapezoidal roof panel Y. , And an adjusting material G provided as needed. For the wall panel P, a normal wall panel (general rectangular panel) 10
In addition, various panels such as a small wall panel 11 are prepared according to the purpose of use. The dimensions such as the width and height of the panels P and Y are determined based on one basic length (module) in the building.

[0004] For example, in the case of the wall panel P, the length is one module length, 1/2 module length, 1/4 module length, 1.5 module length, 2 module length, or the like.
Panels having a width or height that is an integral multiple of a unit length equal to a fraction of the module length are prepared. In the case of the house-cutting panel Y, for example, the unit length (a) is set for the 1/1 roof slope shown in FIG.
The maximum width is four times the length of the roof, and each of the 2/3, 1/2, 1/3, and 1/12 roof slopes shown in FIGS. The maximum width is eight times the length a.

[0005] For any roof slope, in addition to the above-described basic width of the house-cutting panel Y, an integral multiple of the unit length a (or twice the length 2a). A substantially triangular or trapezoidal panel having a base line segment of length is prepared. That is, as an example, the case where the roof slope is 1/2 will be described. The eight pieces Y1, Y2, Y3, and Y in FIG.
Eight other pieces (or the largest roof panel made of Y4, Y5, Y6, Y7, and Y8, the triangle panel made of Y1 to Y4, the trapezoid panel made of Y5 to Y8, and the trapezoid panel made of Y3 to Y6, etc. , 4 pieces when the minimum length is 2a)
Panels prepared by appropriately combining are prepared. The same applies to other roof slope panel panels.
Note that for a roof slope of 1/1, a combination of four pieces (or two pieces when the minimum length is 2a) is used.

Incidentally, in recent years, in designing a house or the like as well as various designs, in order to save labor, CAD has been used.
(Computer-aided design) system may be used. In a general CAD system, shape data, graphic data, and other data of members serving as design elements are stored in advance as a database, and these data are called at the time of design, and each member is arranged on a draft. This creates a draft.

Therefore, in a conventional CAD system for a house, data on a wall, a floor, a ceiling, etc. is read out by determining a layout, and data on a roof is read out by determining a roof shape, such as a ridge or gable. By determining the members such as windows and doors and their positions, data on the windows and doors is read out, and the corresponding members are arranged at corresponding positions on the display. As a result, the shape of the house is shown on the display as a figure (three-view drawing or perspective view) and is output as a design drawing.

[0008]

In the case of a prefabricated house by the above-mentioned panel method, panels having predetermined shapes and dimensions must be arranged on the floor, walls and roof. Therefore, when designing with a CAD system, data of floor panels of various sizes is stored for floors, and wall panels and small wall panels of various shapes and sizes are stored for walls. And data on roof panels, etc., and on the roof, data on roof panels of various sizes are stored, and a panel of appropriate shape and size is selected from those data. Must be assigned to appropriate locations.

However, in a conventional CAD system design in which panels are simply mechanically allocated in order from the end, the following problems may occur. In other words, floors, walls, and roofs are determined according to the design requirements of the supplier, and are not necessarily designed according to the shape and dimensions of each panel. It is extremely likely that inefficient panel layout will be performed, for example, a plurality of small panels are arranged where possible.

Further, in the case where a house is to be constructed with inefficient panel layout as described above,
It is necessary to manufacture a custom-sized panel to fill the gap, or to manufacture a large number of small panels having lower production efficiency than a large panel, which has a drawback of lowering panel productivity. . In addition, at the construction site, the use of small panels or panels that fill gaps increases the work of joining panels to each other, and increases the time and effort required to manufacture members (adjustment materials) to fill small gaps between panels. There were also disadvantages.

[0011] Therefore, if the layout of the panels is poor, not only will the productivity of the house decrease, but also the construction cost will increase. In particular, when the upper half supports the roof 2 as a part of a hut, as in the wall 1 shown in FIG. 26, the upper half is irregular along the roof gradient. It is extremely difficult to combine the rectangular wall panel P and the substantially triangular or trapezoidal house-cutting panel Y efficiently and automatically without any gaps as much as possible. Met.

[0020]

According to the wall panel allocating apparatus of the present invention, the horizontal net line segment creating means creates the horizontal wall panel net line segments at a pitch obtained by multiplying the unit length by the roof gradient. In a roof cut panel in which the width in the vertical shape is an integral multiple of the unit length, even if the vertical shape is different, the bottom line in the vertical shape is always the horizontal wall panel net line group. Matches any of the line segments.

Therefore, when a wall panel is selected from the wall panel storage means by the wall panel selection means, the upper side line segment in the vertical shape of the wall panel coincides with any line segment of the horizontal wall panel net line group. If a wall panel having an upright shape is selected, the roof panel and the wall panel can always be allocated without generating a gap therebetween. Therefore, it is not necessary to provide an area for arranging a custom-sized panel or an adjusting material.

In particular, by setting a horizontal wall panel net line segment as high as possible as the horizontal line panel net line segment in which the upper side line segment in the vertical shape of the wall panel coincides, it is possible to select a house cut panel as large as possible while maximizing it. The selection of wall panels becomes possible, thereby preventing small panels from being inadvertently allocated.

If an upright wall panel whose upper side line segment coincides with the horizontal wall panel net line segment is not stored in the wall panel storage means, the uppermost horizontal wall panel net line segment is placed as far as possible. In addition, a wall panel is selected so that the upper side line of the shape formed by combining the elevation shape of the adjusting material and the elevation shape of the wall panel coincides with each other. While making selections, it is possible to select as large a wall panel as possible, reduce the number of adjustment materials allocated between the wall panel and the roof panel as much as possible, and without providing an area for custom-size panel allocation I'm done.

The first wall area setting means sets the lower half of the entire panel allocation area as a wall area to which only the wall panel is allocated, and the roof area setting means sets at least one area excluding the wall area. By being configured as a house-cutting area to which the house-cutting panel is allocated, a house-cutting area of the entire panel allocation area, that is, an area in which a combination of the house-cutting panel and the wall panel is considered can be made as small as possible. Therefore, it is possible to prevent the layout from being inadvertently combined with the roof panel and the wall panel even where the wall panel should be originally allocated.

[0025] By the first layout area setting means for allocation,
A second wall area setting means for sequentially setting an allotment area for allocating an elevation of a roof panel in the roof area from the eaves side of the roof area to the ridge side; Thereby, the roof cutting area excluding the layout roof cutting area is configured to be a wall area that can be filled by the allocation of the elevation shape of the wall panel. Panels can be assigned.
In particular, it is effective for allocating a roof panel to a roof area where a roof is located above a girder member of a house.

The mixed area setting means divides the house cut area into a plurality of mixed areas according to the width of the largest vertical shape of the cut panel, and the second assigned house cut area setting means The upper half of the mixing area is an allocation roof area for allocating the vertical shape of the largest roof panel, and the third wall area setting means sets the mixing area excluding the allocation roof area as a wall. Since the wall area can be filled by the allocation of the vertical shape of the panel, the roof panel can be efficiently allocated in the roof area. In particular, this is effective for allocating a house-cut panel to a house-cut area where the roof is located below the girder material of the house.

If there is no roof cut panel corresponding to the allocation target portion of the layout roof cut area, the layout target area is set to the site frame area by the site frame area setting means. Accordingly, it is possible to cope with a case where a wall supporting a roof having an irregular slope or shape is designed.

When the vertical line portion of the vertical shape of the roof cut panel corresponding to the allocation target portion of the layout roof cut area protrudes from the allocation target portion, the protruding portion is set by the on-site machining area setting means. Is used as the on-site machining area, so that it is possible to cope with a case where a wall is designed so that a roof cut panel cannot be allocated without any excess or shortage.

At this time, if the end of the panel allocation area 200 is shifted from the core by the dimension d due to winning or losing (see FIG. 11 (losing) and FIG. 12 (winning)) (step S12).
0), the end line segment of the vertical wall panel net line segment 101 is adjusted so as to coincide with the core (step S130), and then the process proceeds to the above-described step S20 of setting a house cutting area.

FIG. 6 shows a specific example of the procedure for setting the house cutting area in step S20. As shown in the figure, first, a wall panel essential line segment 110 is created (step S200). The creation process is as follows (see FIG. 13). In other words, along the vertical wall panel net line segment 101a passing through the highest point A (in this example, the point corresponding to the ridge) in the panel layout area 200, the maximum elevational shape of the roof cut panel Y from the point A (indicated by hatching). A point B which is lowered by the length of the vertical line segment 111 in the indicated portion) is obtained, and a horizontal line segment 110a of one pitch length passing through the point B is created. In the case of a roof, only one pitch of horizontal wall panel essential line segment 110 having a pitch length descending step by step toward the eaves of one side (one side only) is sequentially created. When the panel layout area 200 is not symmetrical (see FIG. 14), when the wall panel required line segment 110 reaches one side edge of the eaves side, the wall panel required on the other eaves side is required. The creation of the line segment 110 is also completed and extended to the side end.

Subsequent to step S200, the height of the wall panel essential line segment 110b having the lowest height, that is, the wall panel essential line segment 110b reaching the side end of the panel layout area 200 is the bottom of the panel layout area 200. If it is higher than the line segment 120 (see FIG. 15) (step S210), the following processing is performed. That is, below the end height h of the panel layout area 200, the dimension smaller than the bottom line segment 120 by an integral multiple (two times in the example of FIG. 15) of the height dimension c of the largest small wall panel. A dividing line 130 is provided at an upper position, and the panel dividing region 200 is vertically divided into two by the dividing line 130. Then, the upper divided half is defined as the house-cutting area 220, and the lower side is set as the internal small-wall area 210 (step S220), and the process proceeds to the above-described step S30 for dividing the house-cutting area.

In step S210, if the minimum line panel essential line segment 110b is lower than the bottom line segment 120, the above-described step S220 is performed.
Without performing the division as described above, the entire panel allocation area 200 is set as the roof cutting area 220 (step S230), and the process proceeds to the above-described step S30 of dividing the roof cutting area.

FIG. 7 shows a specific example of a procedure for dividing the roof cutting area in step S30 in the case of a girder roof. As shown in FIG.
Is equal to or greater than the length of the vertical line segment 111 in the vertical shape of the largest house-cut panel Y from the dividing line 130 to the highest point A (the height of the house-cut area 220). If it is longer (step S300), a group of bottom line segments for the layout-cutting area for allocation is created as follows.
The creation process is as follows (see FIG. 16). That is, an allocation roof cutting area bottom line 140a corresponding to the bottom line in the roof cutting panel Y is created at the eaves front of the roof cutting area 220 (step S301). Then, the upper rear end C of the vertical shape of the house-cutting panel Y having the created layout-side house-cutting area bottom line 140a as the base coincides with the ridge (point A) of the house-cutting area 220 or more. Until it is located at a higher position (step S303), the layout-use cutting area bottom line segment 14 in a stepped shape toward the ridge portion
0 are sequentially created (step S304).

It should be noted that the bottom line segment 140 for the layout of the house cutting area for allocation
In the creation of (140a), the selection of the house-cut panel Y is performed by the wall panel selecting means 41 as described above, and the horizontal wall panel net line segment 10 as high as possible is selected.
In consideration of an upright wall panel P having an upper side line segment that matches 0, or a combination of the wall panel P and the adjusting material G, an upright roof panel is selected as much as possible. Needless to say, this is performed.

Then, when the creation of the group of the bottom line segments for the layout area for the layout is completed, the layout area 220 is divided into the upper side and the lower side of the bottom line segment 140 for the layout area, and the upper half of the divided area is formed. Is an allotment area 221 (see FIG. 17, hatched portion), and the lower side is an internal small wall area 2
25 (step S305). In the above step S300, if the height of the house-cutting area 220 is shorter than the length of the vertical line segment 111 in the vertical shape of the largest house-cutting panel Y, the entire house-cutting area 220 is assigned to the house-cutting for layout. The area 221 is set (step S302).

Subsequently, a surplus area corresponding to the deviation generated from the vertical wall panel net line segment 101 due to the winning or losing is created in the layout roof area 221 (step S30).
6). More specifically, if the winning / losing attribute of the rear end of the roof cutting panel Y is winning, the joint girder arrangement area 250 (FIG. 1)
The remaining area 251 is created in a state where it is lowered by an amount indicated by a two-dot chain line in FIG. 8 (see FIG. 18). In addition, when the attribute of the front end of the roof-cut panel Y is winning, nothing is arranged for the area 252 (the area shown by the two-dot chain line in FIG. 19) that originally protrudes from the vertical wall panel net line segment 101. No (see FIG. 19).

Next, the inner small wall regions 210, 225
Is divided into internal small wall areas for allocation (step S307),
The process proceeds to the panel allocating process in step S40. The internal small wall area 260 for allocation is created by horizontally dividing the internal small wall areas 210 and 225 by horizontal lines (see FIG. 20).

FIGS. 8 and 9 show a specific example of the procedure for dividing the roof cutting area in step S30 in the case of a girder roof. As shown in FIG. 8, first, when the height of the house-cut area 220 is equal to or longer than the length of the vertical line segment 111 in the vertical shape of the largest house-cut panel Y (step S350). Then, a mixed area 230 is created (step S351). And the mixed area 230
Is the same as the width dimension in the vertical shape of the maximum roof panel Y as described above (step S353), the area corresponding to the vertical shape of the maximum roof panel Y is allocated to the layout roof panel. An area 231 is formed, and the lower side thereof is the wall area 23.
5 (step S354). In step S353,
If the width of the mixed region 230 is smaller than the above-described dimension, the process proceeds to step 355 in FIG.

The following processing is performed depending on whether or not the mixed area 230 can be divided without excess or deficiency by the optimal combination of the roof panel Y and the wall panel P (step S355). When division is possible without excess or deficiency (see Fig. 21)
, The upper half of the mixing area 230 is allocated
1 and the lower half thereof as a wall region 235 (step S
356). On the other hand, when the image cannot be divided as described above (FIG. 2)
2), the mixed area 230 is divided into a wall area 235 corresponding to the largest wall panel P that fits within the area 230 and an upper area 232 other than the wall area P (step S35).
7) Further, the upper area 232 is assigned to the house-cutting panel Y that fits in the area 232, and the layout-use house-cutting area 231
And the remaining area 233 (step S358).

Steps S354, S356, S35
Subsequent to 8, the height of the wall region 235 is equal to or smaller than the minimum height of a general rectangular panel (general wall panel) (for example, a length four times the unit length a). If it is larger (step S359), the wall area 235 is set as an allocation rectangular area 236 to which the general rectangular panel 10 is allocated (step S360). On the other hand, when the height of the wall region 235 is smaller,
5 is set as the internal small wall region 237 (step S361).

In step S350, if the height of the house-cutting area 220 is shorter than the length of the vertical line segment 111 in the vertical shape of the largest house-cutting panel Y, the entire house-cutting area 220 is allocated. The house cutting area 231 is set (step S352).

Steps S352, S360, S36
Subsequent to step 1, a surplus area corresponding to a shift generated from the vertical wall panel net line segment 101 due to winning or losing is created in the layout roof area 231 (step S362). Specifically, the case of the girder roof (see FIGS. 18 and 19)
Similarly to the above, the remaining area 25 excluding the joint girder arrangement area 250
1 and setting of an area 252 where nothing is arranged. Thereby, the panel arrangement as shown in FIG. 23 is made. Next, the internal small wall areas 210 and 237 are divided into allocation internal small wall areas 260 (see FIG. 20) (step S36).
3), and proceed to the panel allocating process of step S40.

FIG. 10 shows a specific example of the panel allocating procedure in step S40. As shown in the figure, first, the general rectangular panel 10 corresponding to the allocation rectangular area 236 is arranged (step S400). Next, the small wall panel 11 corresponding to the internal small wall area 260 for layout is arranged (step S410). Internal small wall area 26 for allocation
0, there is an area having a size smaller than the smallest small wall panel 11 in both width and height (step S).
411), the generated area is set as a surplus area (step S412).

Subsequently, a special panel corresponding to the side wall area of the overhang portion where a part of the upper floor protrudes from the outer wall of the lower floor or the wall area where the facing room attribute is the bathroom is used. It is arranged (step S420).

Next, the layout cutoff areas 221 and 231 are allocated.
When there is no corresponding roof-cut panel Y in the portion to be allocated (step S430), the area is set as a site frame area (step S431). On the other hand, if there is a corresponding house-cut panel Y in step S430, the corresponding house-cut panel Y is arranged in the layout house-cut areas 221 and 231 (step S432). At that time, in the case of a girder roof,
One house-cut panel Y is assigned to one layout-use house-cut area 221 bottom line segment 140 for the layout-use house-cut area 221 (see FIG. 24).

In the case where the housekeeping panel Y is arranged so as to protrude from the portion to be allocated (step S433), the protruding part (over part) is processed by the on-site machining area 240. (Step S434). At this time, the front end side of the house-cut panel Y is aligned with the corresponding portion in the layout area, and the rear end of the house-cut panel Y is cut vertically (see FIG. 25).

After arranging each panel, the above-mentioned step S412 is performed.
The adjusting material G corresponding to the surplus area generated in the internal small wall area 260 for allocation and the other surplus areas 233 and 251 in FIG.
Are arranged (step S440). At this time, if an area smaller than the minimum one of the adjusting materials G occurs in the remaining areas (step S441), the area is set as a site frame area (step S442).

As described above, the data on the arranged panels Y and P (10, 11) and the adjusting material G, and the designated on-site machining area 240 and on-site frame area are registered and registered. It is stored in the auxiliary storage device 4 (step S4
50). Thus, the process of allocating the wall panel is completed.

When the layout has been completed, in the CAD system, the allocated wall panels P (10, 11) and house cut-off panels Y stored in the auxiliary storage device 4 are stored.
Product code No. for ordering By retrieving the price, unit price, etc., it is possible to create a quote for the corresponding wall and an order for the panel and the adjusting material. In addition, it is possible to print (output) the quote and the purchase order. It is needless to say that a design drawing of the wall can be printed.

According to the above-described embodiment, the wall surface panel allocating apparatus is capable of controlling any one of the line segments 1 in the horizontal wall panel net line group.
Since the largest possible wall panel P having an upper side line segment that matches 00 is selected, and the house panel Y just combined with the selected wall panel P is selected. The panel Y and the wall panel P can be allocated as large as possible without generating a gap therebetween. Therefore, not only does not need to provide an area for arranging a custom-sized panel or the adjusting material G, but also it is possible to prevent the carelessly allocating of a small panel, thereby efficiently allocating panels and saving design work. Needless to say, avoidance of panel productivity reduction and labor saving of panel joining work at a building site are achieved, and improvement of house productivity and reduction of building cost are achieved.

Further, when there is no wall panel P having an upper side line segment which coincides with any horizontal wall panel net line segment 100, the wall panel allocating apparatus combines the wall panel P with the adjusting material G. Is considered, and a combination in which the upper side line segment in the combination matches any horizontal wall panel net line segment 100 is selected, so that panel allocation is efficiently performed. Therefore, even when the adjusting material G must be used, the number of the adjusting materials G allocated between the wall panel P and the roof panel Y is reduced as much as possible, and the gap which cannot be filled even with the adjusting material G is used. Can be prevented as much as possible, so that there is no need to provide an area for allocating a custom-sized panel.

The wall panel allocating apparatus and the CAD system to which the panel panel is applied are arranged such that the upper side line segment of the wall panel P or the upper side line segment obtained by combining the wall panel P and the adjusting material G is connected to any horizontal line. It is needless to say that the configuration in the above embodiment is not limited at all, as long as the wall panel P, the roof cutting panel Y and the adjusting material G are allocated so as to match the wall panel net line segment 100. Also,
The specific procedure of the panel allocation process is not limited at all by the above embodiment.

[0075]

According to the wall surface panel allocating apparatus of the present invention, the horizontal net line segment creating means creates a horizontal wall panel net segment group at a pitch obtained by multiplying the unit length by the roof gradient, and the line segment group is created. Because the index is used to consider the combination of the roof panel and the wall panel, the roof panel and the wall panel can be allocated without generating a gap therebetween, and a custom-sized panel or There is no need to provide an area for allocating adjustment materials and the like. In addition, it is possible to allocate as large a wall panel as possible while selecting a house partition panel that is as large as possible within a range that can be allocated without excess and deficiency, thereby preventing a carelessly small panel from being allocated. Therefore, panel allocation is efficiently performed, avoiding a decrease in panel productivity and saving labor in panel joining work at a building site, and improving house productivity and reducing construction costs.

If an upright wall panel whose upper side line segment matches the horizontal wall panel net line segment is not stored in the wall panel storage means, the horizontal wall panel net line segment group is used as an index. Since the combination of the roof panel, the wall panel, and the adjustment material is considered, the panel layout is efficiently performed, and therefore, the number of the adjustment materials allocated between the wall panel and the roof panel is reduced as much as possible. Or
It is possible to prevent a gap that cannot be filled even with the adjusting material, and it is not necessary to provide an area for allocating a custom-sized panel.

The lower half of the entire panel layout area is defined as a wall area, and the upper half area excluding the wall area is defined as a roof area. It is sufficient to allocate the wall panels without including them, and consider the combination of the roof panel and the wall panel only in the roof area. It is possible to prevent the layout from being inadvertently combined with the roof panel and the wall panel.

From the eaves side of the house-cutting area to the ridge side, a house-cutting area for allocation is sequentially set in the house-cutting area, and the house-cutting area excluding the area-cutting-off area is defined as a wall area. By doing so, it is possible to efficiently allocate the house-cut panel in the house-cut area. In particular,
This is effective in allocating a house-cut panel to a house-cut area in a case where the roof is located above the girder material of the house.

The roof cutting area is divided into a plurality of mixing areas, the upper half of each mixing area is used as an allocation roof cutting area, and the mixing area excluding the allocation roof cutting area is used as a wall area. With this arrangement, the house-cut panel can be efficiently allocated in the house-cut area. In particular, this is effective for allocating a house-cut panel to a house-cut area where the roof is located below the girder material of the house.

When there is no roof cut panel corresponding to the allocation target portion of the layout roof cut area, the allocation target portion is set to the site frame area by the site frame area setting means. Can be used to design a wall that supports a roof with irregular slopes or shapes.
It can be designed according to any design requirements of the supplier.

If the vertical line portion of the vertical shape of the roof cut panel corresponding to the allocation target portion of the layout roof cut region protrudes from the allocation target portion, the protruding portion is set by the on-site machining area setting means. Is designed to be the on-site machining area, so it is possible to design a wall that can not be assigned a cut-off panel without any excess or shortage, and it can respond to any design requirements of the supplier. Can be designed accordingly.
