DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention
The present invention relates to a hut beam allocating device for allocating hut beams such as girders (roof beams, B beams (described later)) and purlins (small beams) that support the roof.

[0002]

2. Description of the Related Art As one method of constructing a prefabricated house, there is known a method of constructing a floor, a wall, a ceiling, a roof and the like of a house by using panels. In this construction method, in a factory or the like, a frame is formed by framing a core material, and a floor material is attached to at least one surface of the frame, thereby floor panels, wall panels, ceiling panels, and roofs. A building is constructed by manufacturing panels and assembling these panels at a construction site.

[0003] In recent years, in various designs,
CAD system consisting of computer system (Com
(Putter-Aided Design) is used, and even in the above-described house, design may be performed using a CAD system. In a general CAD system, shape data, graphic data, and other data of a member serving as a design element are stored in advance as a database (D / B), and these data are called up at the time of design, and the data of the display is read. By arranging each member on the drafting, the drafting is created, and the design work can be saved.

Therefore, on a display of a conventional CAD system of a house, data of a wall, a floor, a ceiling, and the like are read and arranged by determining a layout,
By determining the shape of the roof (building, gable, etc.), the data of the roof is read and arranged. By determining the members such as windows and doors and their positions, the data of windows and doors are read. The shape of the house is displayed on the display as a graphic (three-view drawing or perspective view) and output as a design drawing.

[0005]

By the way, in the design of a prefabricated house using such panels, floors,
It is necessary to assign panels of predetermined size and shape to walls, ceilings, and roofs. Further, on the CAD system, floors, walls, ceilings, and roofs are not necessarily designed according to the shape of the panel, but are determined according to the design requirements of the supplier. If the panels are arranged sequentially and mechanically from the edge of the panel, there is a possibility that gaps will be created or multiple small panels will be placed where large panels need to be placed, resulting in inefficient panel layout. it was high.

As described above, when a house is to be constructed while allocating inefficient panels, a custom-sized panel for filling the gap may be manufactured at a factory, or compared with a large panel. Thus, it is necessary to manufacture many small panels with low production efficiency, which has reduced the productivity of panels in factories. Further, in a construction site, the use of small panels or panels that fill gaps increases the number of panel joining operations, or requires members to fill small gaps between panels.

[0007] Therefore, if the method of allocating panels is bad, the productivity of the house is reduced and the cost is increased.

In particular, since a roof is formed in a three-dimensional manner, it is difficult to lay panels on a plane such as a wall or a floor, and a plurality of inclined roof surfaces are separately handled. At the same time, it was necessary to determine the layout of panels using side sectional views of the roof slope. In addition, in the case of a composite roof, the number of types of roof surfaces increases as compared to a normal ridge roof or gable roof, making it more difficult to allocate panels. It was extremely difficult to assign.

[0009] The allocation of hut beams, such as girders (roof beams, B beams), and purlins (shoots) that support the intermediate portion of the roof panels, is also efficiently performed. It is desired to be automated.

Accordingly, an object of the present invention is to provide a roof for a building constructed from panels as described above, which can efficiently and efficiently provide a hut beam for supporting a joint or an intermediate portion of a roof panel disposed on the roof surface. It is an object of the present invention to provide a hut beam allocating apparatus for allocating the huts.

[0011]

It is a climbing beam formed in a bent (Bent) shape. The use of the climbing beam 3a can reduce the number of parts of the beam, and the land beam 5 is not disposed on the attic, so that the space in the attic can be increased.

As shown in FIG. 7, a straight climbing beam 3b arranged along the slope of the roof surface is also a type of the B beam 3.

As shown in FIGS. 3 and 4, such a beam having at least one end hung on the B beam 3 and the roof beam 2 is referred to as a small beam 4.

That is, only the beam whose both ends are supported by the walls 1 and 1 is a girder (the roof beam 2 and the B beam 3), and at least one of both ends of the beam is supported by the roof beam 2 or the B beam 3. Becomes the small beam 4.

As shown in FIG. 2, in the roof constituted by the roof panels P, P, P,..., The roof panels P, P, The core members (not shown) of P, P,... Support the roof surface.

When the above roof panels P, P, P,... Are arranged, the joints of the roof panels P, P, P,. A hut beam B for supporting the upper and lower edges of the roof panels P, P, P,... That is, along the upper and lower joints of the roof panels P, P, P,..., The roof beam 2, the horizontal portion 3d of the B beam (climbing beam) 3a, and the small beam 4
Is arranged.

Next, the shed beam allocating device will be described with reference to the basic configuration of the allocating device shown in FIG.

Data designed on the D system is stored. The auxiliary storage device 12 stores data indicating the shape of the roof as data designed by the CAD system.

Note that among the roof shapes stored in the auxiliary storage device 12, the roof shape data used in the layout device is a roof on a plan view as shown in FIG. 9 and subsequent figures. Further, in the auxiliary storage device 12, the roof on the plan view includes an outer peripheral line indicating the outer periphery of the roof, a ridge line (showing a ridge) that divides each roof surface of the roof, a corner ridge line (showing a corner ridge), and The valley corner line (indicating the valley corner), the outer wall line that indicates the junction between the sloping roof surface and the outer wall, and the intersection of the horizontal plane with the horizontal plane that includes the horizontal portion of the outer wall line And a digit line indicating. The roof on the plan view also includes a wall line indicating the position of an inner wall (support wall or load-bearing wall) other than the outer wall.

Further, in the auxiliary storage device 12, the permissible value of the length of the roof panel is stored as a data table corresponding to the inclination angle of the roof, the area where the snow amount is different, and the type of the roof material having the different weight. . The values registered in this data table are the length (allowable value) of the roof panel along the inclination direction of the roof determined on the basis of the strength of the roof panel, and are arranged on the outer wall line of the roof It shows the length (initial allowable value) in the plan view of the upper edge of the roof panel and the outer wall line.

The length in the plan view of the roof panel, which is the allowable value or the initial allowable value, refers to the horizontal distance between the upper and lower edges of the roof panel when the roof panel is arranged on the roof surface (a triangular roof). In the case of a panel, for example, the horizontal distance between the vertex and the base) is shorter than the actual length of the roof panel. The length of the roof panel in the plan view is
The unit is a module described later.

Further, the values (allowable values,
The initial allowable value) is the type (1/12, 1/3, 1/2, 2/3, 1/1) of the roof inclination angle (slope), which will be described later, and an area (general A) divided by the amount of snowfall. , General B, Heavy Snow A,
Heavy snow B, heavy snow C) and the type of roofing material (iron plate, asbestos plate,
Tiles). The permissible values for roof slopes, areas with different amounts of snowfall, and roofing materials with different weights are determined based on the strength of the roof panels as described above, and When the length of the panel in the plan view is within the above-mentioned allowable value, the roof panel is arranged at an angle corresponding to the inclination of the roof, and the roof panel is supported by beams at the upper and lower side edges thereof. ,
It is designed to sufficiently withstand the load due to snow on the roof.

As for the initial allowable value, since the roof panel arranged on the girder line is supported at the upper end of the outer wall at the girder line, the strength of the roof panel supported on the outer wall of the girder line If the length from the girder line to the upper edge of the roof panel is within the above-mentioned initial allowable value, sufficient strength can be maintained.

In the data table, a snow stopper is attached to the roof (to prevent the snow gutters or the like from being damaged due to the snow sliding down from the roof, and as a result, the amount of snow accumulated on the roof is increased). Is provided or an initial allowable value is provided.

The arithmetic processing unit 11 has a function as a well-known CAD system for a house, and creates a reference line on a roof surface designed using the arithmetic processing unit 11, and based on the reference line. And a function of arranging the shed beam B and the roof panel P on the roof surface.

Since the reference line indicates at least the position of a hut beam (generally called a main building) B arranged at a right angle to the inclination direction of the roof surface, in this embodiment,
Hereinafter, it is referred to as a purlin line. In addition, the main purlin line includes a relative purlin line indicating the position of the upper and lower joints of the roof panels and the shed beam supporting the joint, and the position of the shed beam supporting the upper and lower side edges of the roof panel. A candidate purlin line, which is provided when the roof has a valley corner as described below, and an absolute purlin line indicating the positions of the upper and lower joints of the roof panels and the shed beams supporting the joints are set. Also, ridge lines are included.

Then, the arithmetic processing unit 11 reads the shape of the roof on the plan view from the auxiliary storage device 12, and reads the allowable value read from the auxiliary storage device 12 along the inclination direction of the roof surface of the roof. Alternatively, it has a function of creating a relative purlin line in a direction substantially perpendicular to the inclination direction of the roof surface for each maximum value of the length of the roof panel to be manufactured. In addition, when the relative purlin line is created for each of the maximum values, the arithmetic processing unit 11 reads the allowable readout from the auxiliary storage device 12 along the inclination direction of the roof surface at a position not overlapping with the relative purlin line. It has a function of creating a candidate purlin line along a direction substantially perpendicular to the inclination direction of the roof surface for each value.

In the arithmetic processing unit 11, the intersection of the valley corner line indicating the valley corner where the two roof surfaces are joined in a valley shape and the ridge line indicating the ridge of the roof on the roof on the plan view. In some cases, the intersection point has a function of recognizing the intersection point as a reference point, and is arranged at a right angle to the inclination direction of the roof surface on the roof surface that is in contact with the reference point and has a portion above the reference point. It has a function of creating an absolute purlin line that includes a reference point and indicates the positions of the upper and lower joints of the roof panel and the beams arranged at the joints. In addition, the arithmetic processing unit 11 recognizes an intersection between the two valley corner lines and the ridge line on the plan view as a reference point,
It has a function of recognizing an intersection of the valley corner line, the ridge line, and the corner ridge line on the plan view as a reference point.

Further, the arithmetic processing unit 11 recognizes, as an auxiliary point, an intersection between the valley corner line and the outer peripheral line or an intersection between the valley corner line and the relative purlin line on the roof on the plan view. On the roof surface where the purlin line is created, an auxiliary line is created along the inclination direction of the roof surface corresponding to the position of the auxiliary point, and the auxiliary purlin line and the absolute purlin line are formed from the absolute purlin line from the reference point. It has the function of limiting to the intersection of.
Further, the arithmetic processing unit 11 compares the absolute purlin line length with a predetermined comparison value to determine whether the absolute purlin line length of the roof surface is longer than the comparative value, and determines whether the absolute purlin line length is longer than the comparative value. When the length is longer than the comparison value, the absolute purlin line is limited as described above. In addition, when the absolute purlin line and the extension line of the ridge line intersect on the roof on the plan view, the arithmetic processing unit 11 intersects the absolute purlin line from the reference point with the absolute purlin line and the extension line. It has a function to limit to.

Here, before describing a method of allocating a hut beam by the allocating apparatus of this embodiment, rules predetermined in designing a roof on the CAD system will be described. This rule is provided to facilitate the design of a building constructed by the panels formed in advance and to make the strength of the designed building equal to or higher than a predetermined standard.

1. A reference length unit is used on a plan view.

First, in the CAD system of this embodiment, when designing a building, the building is designed in units of a reference length (module) on a plan view. And the lowest unit is 1/4 or 1
/ 8 modules are used. In designing a building, the basic length is set to one unit, so that one module does not become the minimum unit but one unit.
The も し く は or ８ module is the minimum unit.

Therefore, the vertical and horizontal lengths of the wall, floor, ceiling and the like are basically designed to be an integral multiple of the 1/4 or 1/8 module. Thus, said wall,
While designing the floor, ceiling, etc. in the module unit,
Walls, floors, wall panels constituting the ceiling and the like, floor panels, ceiling panels and the like are designed in units of the module, that is,
By standardizing the shape of each panel on a module-by-module basis, it is possible to easily design a building constructed from the panels.

If there is a win or a loss in the connection between the panels or the joint between the panel and another member, the size of the panel is shifted from the module unit by the amount of the win or loss. In addition, the design of the building does not necessarily need to be performed on a module-by-module basis.If an efficient building design cannot be performed on a module-by-module basis due to site conditions, etc. It can be handled by manufacturing.

When designing the roof, when the vertical and horizontal sizes of the roof surface and the roof panel are set to the module unit, the roof is inclined with respect to the ceiling or the floor and the roof surface is formed. And the design of the floor and ceiling will be misaligned, making it difficult to design the roof corresponding to the floor and ceiling, so the roof projected on the plan was designed in units of modules. . By designing the roof projected on the floor plan in units of modules, it is no longer necessary to determine the layout of roof panels based on cross-sectional views of each roof surface with a slope of each roof surface as in the past, and the roof plane The layout of the roof panels can be determined from a single sheet.

The lines indicating the upper and lower edges of the roof panel in the plan view are the upper and lower edges of the lower surface of the roof panel. Also, as described above, by setting the length in the plan view as a module unit, the length of the roof panel in the module unit on the plane is different from the actual length of the roof panel, and the roof panel is a wall panel. However, the roof panel can be standardized by standardizing the inclination angle of the roof surface as described later.

2. Standardize the inclination angle of the roof surface of the roof.

The roof slope is 1/12, 1/3, 1/2,
There are five types, 2/3 and 1/1. In addition, when the roof shape is treated as a gable, all of the roof gradients can be used. However, when the roof shape is treated as a ridge, only the 1/2 and 2/3 gradients can be used. It can be used. In the ridge roof, all roof surfaces of the ridge roof have the same slope.

3. Standardize the eaves on the roof.

The length of the roof portion extending from the outer wall line (projection of the eaves) is １ ／, 、 ３, ／ in the １ ／ module unit (including some ８ module units). 4,7 /
8, one module is set. However, when the gradient is 1/1, the 7/8 and 1 module units are not used.

These rules are provided for facilitating design and construction. In the layout apparatus of this embodiment, a reference line can be created even on a roof surface deviating from the rules. It is. However, if it deviates from the above rules, the strength is recalculated when designing,
When actually building a building, it is necessary to use a non-standard roof panel or the like, and there is a possibility that productivity of design and construction is reduced.

Next, the assignment of the shed beam B to the roof on the plan view in which the purlin line is created based on the above rules will be described. Here, the purlin line refers to a relative purlin line, a candidate purlin line, an absolute purlin line, and a ridge line as described above.

1) The arrangement position of the beam B will be exemplified. FIG. 9 shows the arrangement of B beams in the case of a simple ridge. 21 is a load-bearing wall line, 22 is a roof surface, 23 is a purlin line, and 24 is a B beam. FIG. 10 shows the arrangement of B beams in the case of an entrance purlin. Similarly, 21 is a load-bearing wall line, 22 is a roof surface, and 25 is a B beam.

The conditions for arranging the B beams are as follows. A position just below the purlin line in a closed area surrounded by the load-bearing wall line and the support wall line (FIGS. 9 and 10 show only the load-bearing wall line and no support wall line) (B beam in FIG. 9 of a simple building) 24) and a position immediately below the wall (B beam 25 of FIG.
Reference). Arrange the B beams so that they do not exceed the maximum length of the purlin.

The arrangement rules of the B beams are as follows. The ridge line is treated as a kind of purlin line. The start and end points of the B beam must be supported by the load bearing wall line and the support wall line. The B beam fits only "vertically". Do not place it at a position that overlaps with the roof beam, main building, load bearing wall line, and support wall line. B
There is no intersection between beams. There is no B beam with the same starting and ending point height. The arrangement of the beams B is performed in consideration of the maximum length of the purlin.

2) The arrangement position of the roof beam will be described.
FIG. 11 shows the arrangement of roof beams in the case of a ridge.
Is a bearing wall line, 22 is a roof surface, 23 is a purlin line, and 26 is a roof beam. FIG. 12 shows the arrangement of roof beams in the case of gables. Similarly, 21 is a load-bearing wall line, 22 is a roof surface, 23 is a purlin line, and 26 is a roof beam. FIG. 13 shows the arrangement of the roof beams in the case of an arbor, and similarly, 21 is a bearing wall line,
22 is a roof surface and 27 is a roof beam.

The conditions for arranging roof beams are as follows. Load-bearing wall line / support wall line (FIGS. 11 to 13 show only the load-bearing wall line and no support wall line). 1
No. 2 roof beam 26) and at the position directly below the end wall (see roof beam 27 in FIG. 13 of the entrance house). Arrange the roof beams so that they do not exceed the maximum length of the main building.

The rules for arranging roof beams are as follows. The ridge line is treated as a kind of purlin line. The starting and ending points of the roof beam must be supported by the bearing wall line and the supporting wall line. Roof beams are stored in two different ways depending on the slope of the roof, "vertical" or "slope." Roof beams must not overlap with B beams, purlins, load bearing wall lines, and support wall lines. There is no intersection between roof beams. The start and end heights of the roof beams are the same. The arrangement of the roof beams will be performed in consideration of the maximum length of the main building.

3) The arrangement position of the purlin (small beam) will be described. FIG. 14 shows the layout of the main building in the case of a ward,
21 is a bearing wall line, 22 is a roof surface, 23 is a purlin line, and 28 is a purlin. FIG. 15 shows an arrangement of a purlin in the case of an entrance purlin. Similarly, reference numeral 21 denotes a load-bearing wall line, 22 denotes a roof surface, and
4 is a B beam and 29 is a purlin.

Thus, the arrangement condition of the purlin is as follows. A position directly below the purlin line in a closed area surrounded by the load-bearing wall line and the support wall line (FIGS. 14 and 15 show only the load-bearing wall line and no support wall line) (see the purlin 28 in FIG. 14 of the wing) ) And the position immediately below the wall (purlin 29 in FIG. 15 of the purlin)
Reference). However, there is no arrangement straddling the girders (B beams, roof beams).

The layout rules of the purlin are as follows. The ridge line is treated as a kind of purlin line. The end of the main building must be supported by B beams, roof beams, bearing wall lines, and supporting wall lines. However, neither end point is supported by the bearing wall line / support wall line. The main house only fits vertically. The main building must not overlap with the B beam, roof beam, load bearing wall line, and support wall line. There is no intersection between the main buildings. The starting and ending point height of the purlin is the same.

Next, a method of allocating the hut beam B by the allocating device will be described with reference to the flowchart of FIG. In this process, the beam members are arranged based on the purlin line, the wife wall, the bearing wall line, the support wall line, the roof surface, and the snow area value.

First, in step S1, the maximum length of the purlin is determined from the snow area value. That is, the auxiliary storage device 12 stores the maximum length of the purlin as a data table (correspondence table of the snow area value and the maximum length of the purlin) shown in FIG. General A
B, heavy snow A, heavy snow B, heavy snow C), the maximum length of the purlin (3 modules, 2.5 modules, 2 modules,
1.5 module).

Subsequently, in step S2, an arrangement closed area is obtained. Here, a method of acquiring the arrangement closed area will be described. a. First, an area which is close to the origin and the smallest is obtained from the area surrounded by the load bearing wall line and the support wall line. b.
Delete the area obtained from the whole. If the processes of a and b are performed until the entire region is exhausted, the regions can be acquired in the order shown in FIG. In FIG. 22, a solid line indicates a bearing wall line and a dotted line indicates a support wall line.

Subsequently, in step S3, the arrangement direction of the large beams (B beams, roof beams) is determined. That is, the auxiliary storage device 1
2 stores the girder arrangement direction as a data table (condition for obtaining the girder arrangement direction) shown in FIG. The condition is as shown in FIG.
a. The direction in which the number of purlin lines is larger in either the x or y direction in the arrangement area is defined as the direction in which the girder is bridged (arrangement direction). b. If the number of purlin lines is in the x and y directions, and the same, the longer span is the bridge direction (arrangement direction) of the girder. c. The number of purlin lines is x,
If the y direction is the same and the span is the same, the direction of the ridge line where the corner ridge lines intersect in the placement area is the direction of the bridge (laying direction)
And d. If it cannot be determined by the methods a to c, the direction in which the girder is bridged (arrangement direction) is x.

Subsequently, in step S4, the girder is moved to the purlin line,
Arrange along the wife wall. This girder is arranged along the purlin line and the wife wall, for example, as shown in FIG. That is, in FIG. 19, 31 is a ridge line, 32 is a wall line,
33 is a main building (small beam), 34 and 35 are large beams (34 is a roof beam, 35 is a B beam), and in accordance with the conditions for determining the arrangement direction of the large beams (see FIG. 18), the right and left central portions are provided. Three roof beams 34,3 along purlin line (including ridge line) in area
4 and 34 are arranged in parallel, and two B beams 35 and 35 along the purlin line are arranged in parallel in the left and right side regions.

Subsequently, in step S5, the girders are arranged so as not to exceed the maximum length of the purlin. The girders are arranged so as not to exceed the maximum length of the main house, for example, as shown in FIG. 20 according to the correspondence table between the snow area value and the maximum length of the main house (see FIG. 17). That is, in FIG. 20, similarly, 31 is a ridge line, 32 is a wall line, 33 is a main house (small beam), 34 and 35 are large beams (34 is a roof beam, and 35 is a B beam).
Further, reference numeral 36 denotes a B beam. For example, the arrangement of FIG. 19 shows that the maximum length of the main house is 3 modules in the general AB area, and the maximum length of the main house is 3 modules in the heavy snow area C. 1.5
In the case of a module, as shown in FIG.
B beam 36 on the left and right sides along the extension of the ridge line,
36 are arranged respectively.

Subsequently, in step S6, the beam is moved to the purlin line,
Arrange along the wife wall. The arrangement of the small beams along the purlin line and the wife wall is performed, for example, as shown in FIG. That is, in FIG.
Is a wall line, 34 and 35 are girders (34 is a roof beam, 35 and 36
Is a B beam) and 37 is a purlin (small beam).
In the arrangement of the zero girder, two purlins (small beams) 37, 37 are respectively arranged between the three B beams 35, 36, 35 in the respective regions on the left and right sides.

The arrangement of the girder and the girder as described above is performed until the remaining area is exhausted.
7, a method for acquiring the arrangement closed area (see FIG. 22)
If there is still an area to be obtained according to the above, the flow returns to the processing in step S2 to repeat the above processing, and if there is no remaining area, the processing ends. Note that the arrangement of the beam members does not consider the roof opening.

Next, with reference to the flow chart of FIG. 23, a method of allocating the girders (B beams and roof beams) by the allocating device will be described. In this process, the specific contents of step S4 in the flowchart of FIG. 16 are performed.
That is, the girder is arranged in the arrangement direction along the purlin line and the end wall in the arrangement closed area.

First, at step S11, a purlin line and a wife wall which are within the arrangement closed area are searched. For example, as shown in FIG. 24, at least a part of the purlin line and the wife wall included in the arrangement area are in the area in the case of the relationship between the wall line indicated by the solid line and the purlin line indicated by the dotted line. , That is, the purlin line.

Such a search is performed until the purlin line and the masonry wall are not found in the area. That is, in the next step S12, if the purlin line and the masonry wall still exist, the next step is performed. Proceeding to S13, if the purlin line and the wife wall are no longer found, the process ends. Subsequently, in step S13, the purlin line and the subordinate axes of the wife wall are checked, and in the next step S14, the girder arrangement direction and purlin line according to the conditions for obtaining the girder arrangement direction (see FIG. 18). When the directions of the masonry walls are the same, the process returns to the step S11 to repeat the above processing. When the arrangement direction of the girder is not equal to the direction of the purlin line and the masonry wall, the process proceeds to the next step S15.

Subsequently, in step S15, a line segment that passes through the purlin line and the wife wall and blocks the arrangement closed area in the arrangement direction is obtained.
As for the line segment passing through the purlin line and the wife wall and intercepting the arrangement area in the arrangement direction, for example, as shown in FIG. 25A, the arrangement area surrounded by the solid line and the purlin line indicated by the dotted line As shown in FIG. 25B, a line segment such as a beam member shown by a bold line in the horizontal direction that passes through the purlin line and blocks the arrangement area, as compared to the relationship.

In the next step S16, the heights on the roof at the start and end points of the line segment are determined. That is, the height of each point corresponding to the roof slope or the like input in advance is read from the database stored in the auxiliary storage device 12. Subsequently, in the next step S17, if the heights of the start point and the end point are different, the process proceeds to step S18.
If the heights of the end points are the same, the process proceeds to step S19. That is, B beams and roof beams are distinguished by differences in the heights of the start point and end point of the line segment that passes through the purlin line and the wife wall and blocks the arrangement area in the arrangement direction. The height of the start and end points of the line segment is different on the roof surface, and the case of the roof beam is the case where the height of the start and end points of the line segment is the same on the roof surface.

FIG. 26 exemplifies a case of a B beam, in which 41 is a wall line, 42 is a ridge line, and 43, 44, 45, 4
Reference numerals 6 and 47 denote B beams, in which two lateral B beams 43 and 43 are arranged in the left side region, and two lateral B beams 44 and 45 including the ridge are arranged in the upper right side. Further, three vertical B beams 46, 47 and 46 including a ridge are arranged on the lower right side. Thus, the B beams 43, 44, 45, 46, 4
No. 7 is different in the height of the start and end points on the roof surface.

FIG. 27 exemplifies a case that becomes a roof beam. Similarly, 41 is a wall line, 42 is a ridge line, 48 is a roof beam, and three lateral beams including a ridge in the left and right central regions. Directional roof beams 48, 48, 48 are arranged. Thus, the roof beam 48 has the same height at the start and end points on the roof surface.

In step S18, the beam B is registered in the database (D / B) of the auxiliary storage device 12, and the process returns to step S11 to repeat the above processing. In step S19, the roof beam is similarly registered in the database of the auxiliary storage device 12, and the process returns to step S11 to repeat the above processing.

Next, the registration of the beam B in the database (D / B) by the allocating device will be described with reference to the flowchart of FIG. In this process, the specific contents of step S18 in the flowchart of FIG. 23 are performed, that is, the B beams are arranged based on the B beam position coordinates and the roof surface.

First, in step S21, a line segment based on the higher end point of the B beam is obtained. A line segment based on the higher end point of the B beam is obtained, for example, as shown in FIG. That is, in FIG. 29, 51 is a ridge line, 52 is a wall line,
Reference numeral 53 denotes a line segment, and the line segment 53 is obtained based on the point having the higher B beam coordinate position on the wall line 52 side.

Subsequently, at step S22, an intersection between the line segment and the roof surface is obtained. The intersection of this line segment with the roof surface is
For example, it is obtained as shown in FIG. That is, in FIG. 31, similarly, 51 is a ridge line, 52 is a wall line, 53 is a line segment based on a point having a higher B beam coordinate position, and 54 is an intersection. An intersection 54 between the line segment 53 based on the higher point and the roof surface indicated by the ridgeline 51 is determined.

Then, in the next step S23, if there is no intersection, the process proceeds to step S24, and if there is an intersection, the process proceeds to step S27.

First, in step S24 when there is no intersection, the B beam position coordinates and the heights of the start point and the end point are registered in the database (D / B) of the auxiliary storage device 12. Subsequently, in step S25, the fit is set (vertical fit). That is, as shown in FIG. 30, the B beam is only set vertically, and the "vertical fit" is set.
Subsequently, in step S26, the roof surface ID is obtained and set, and then the process ends. The roof surface ID is stored in the auxiliary storage device 12 in advance, and reads and registers information corresponding to the B beam (up-and-down beam) registered as described above.

In step S27 when there is an intersection, it is checked whether the intersection is at an end point. Then, in the next step S28, when the intersection is at the end point, the process proceeds to step S29, and when the intersection is at a position other than the end point, the process proceeds to step S32.

First, step S when the intersection is at the end point
At 29, the B beam position coordinates and the heights of the start point and end point are registered in the database (D / B) of the auxiliary storage device 12. When this intersection is at the end point of the line segment,
As shown in (a), the end point of the line segment 55 is the intersection 54. In such a case, a climbing beam 56 as shown in FIG. 33 (b) is arranged. Then, step S
After the fitting is set (vertical fitting) at 30, the roof surface ID is determined and set at the next step S31.
The process ends.

In step S32 when the intersection is other than the end point, the gradient of the roof surface is obtained. The roof surface gradient is stored in the auxiliary storage device 12 in advance, and is read out based on input data. Subsequently, step S33
Then, the height of the joint girder is obtained from the slope of the roof surface. As shown in FIG. 30, the connecting girder is a girder member having a triangular cross section interposed between a B-beam that fits vertically and a slope of a roof surface perpendicular to the B-beam. It is stored in advance in association with the slope of the roof surface.

Subsequently, in step S34, a line segment is obtained based on the height obtained by subtracting the connection girder from the higher end point of the B beam. Subsequently, in step S35, an intersection between the line segment and the roof is obtained. As shown in FIG. 32A, the case where such an intersection is at a position other than the end point is that the line segment 53 is a ridge line 51.
32. In such a case, a climbing beam 57 as shown in FIG. 32B is arranged.

Subsequently, in step S36, the coordinates (B) of the auxiliary storage device 12 are set using the position coordinates of the beam B, the height of the start and end points, the position of the intersection, and the height as the position coordinates of the refraction point.
/ B). Subsequently, in step S37, the position, height, and fit (vertical fit) of the intersection (bending point) are similarly registered in the database. Then, the next step S3
In step 1, the roof surface ID is obtained and registered in the database in the same manner, and the process is terminated.

Next, registration of a roof beam to the database (D / B) by the allocating device will be described with reference to the flowchart of FIG. In this process, the specific contents of step S19 in the flowchart of FIG. 23 are performed. That is, the roof beam is stored in the database (D / B) based on the roof beam position coordinates, the height of the start and end points, and the roof surface. ).

First, at step S41, the coordinates of the roof beam position are registered in the database (D / B) of the auxiliary storage device 12. Then, in step S42, the gradient of the roof surface is determined. The slope of the roof surface is stored in the auxiliary storage device 12 in advance as described above. Subsequently, step S4
In 3, we ask for a roof surface construction method. The roof surface construction method is also stored in the auxiliary storage device 12 in advance. Continued
In step S44, the fit is determined from the obtained roof surface construction method and roof surface gradient.

Then, in the next step S45, if the fit is vertical, the process proceeds to step S46, and
If the coordinates are the same as the ridgeline, the process proceeds to step S51.

First, step S4 when the fit is vertical
In step 6, the fit (vertical fit) is registered in the database (D / B) of the auxiliary storage device 12. Subsequently, in step S47, the height of the joint girder is obtained from the slope of the roof surface. The connecting girder is a girder member having a triangular cross section interposed between a vertically installed roof beam and a slope of a roof surface perpendicular to the roof girder. It is stored in advance in association with the gradient.

Subsequently, in step S48, the height obtained by subtracting the joint girder from the end point of the roof beam is set as the height of the start and end points of the roof beam. Subsequently, in step S49, the starting point of the roof beam,
The height of the end point is stored in the database (D
/ B) and then terminate the process.

In step S51 in the case of the same position coordinates as the ridgeline, the fit (gradient fit) is registered in the database of the auxiliary storage device 12. That is, FIG.
As shown in (1), when the position coordinates are the same as those of the ridgeline, it is a slope fit, and the “slope fit” is registered. continue,
In step S52, the heights of the roof beam start point and end point are similarly registered in the database, and the process ends.

FIG. 36 shows a data table (correspondence table of roof type and roof slope) for discriminating the fitting of roof beams. In the case of 1/2 and 2/3, "vertical fit"
In the case of gable treatment and a gradient of 1/12, 1/3, or 1/2, it is "gradient fit".

Next, with reference to the flowchart of FIG. 37, a description will be given of a method of registering a girder (B beam, roof beam) in the database (D / B) so as not to exceed the maximum length of the main building by the allocating device. In this process, the specific contents of step S5 of the flowchart of FIG. 16 are performed, that is, the arrangement beam, the arrangement direction, the position coordinates of the girder, the maximum length of the purlin, the B beam based on the roof surface, Register the roof beams in the database (D / B).

First, in step S61, a girder included in the arrangement closed area is determined. This girder is obtained, for example, as shown in FIG. That is, in FIG. 38, 61 is a ridge line, 62 is a wall line, and 63 is a B beam.
For example, two B beams 63, 63 included in the A section are obtained.

In the next step S62, if there is a girder, the flow advances to the next step S63.
If there is no girder, the process ends. Subsequently, in step S63, the interval between the current girder and the next girder is obtained. That is, for example, as shown in FIG. 39 similar to FIG. 38, the arrangement interval 1 of the B beams 63, 63 in the section A is checked.

In the next step S64, if the interval is equal to or less than the maximum length of the purlin (see FIG. 17), the process returns to step S61 to repeat the above processing, and the interval is set to the maximum length of the purlin. If it exceeds
Proceed to the next step S65.

Subsequently, in step S65, an arrangement interval is obtained from the interval and the maximum length of the purlin. Then, in the next step S66, if the interval exceeds the maximum length of the purlin, the process proceeds to the next step S67, and if the interval is less than the maximum length of the purlin, the process ends.

Subsequently, in step S67, a point which has been moved from the current position of the girder by the arrangement interval in the direction of the next girder is determined. The point moved by the arrangement interval in the direction of the next girder from the current girder position is obtained, for example, as shown in FIG. That is, in FIG. 40, reference numeral 64 denotes the current beam, 65 denotes the next beam, 1 denotes the arrangement interval, and A denotes the obtained point.
The point A moved in the direction of by the arrangement interval l is obtained.

Subsequently, in step S68, a line segment passing through the obtained point and blocking the arrangement area in the arrangement direction is obtained (see FIG. 25). Then, in the next step S69, the heights of the start point and end point of the line segment are determined. That is, the height of each point corresponding to the roof slope or the like input in advance is read from the database stored in the auxiliary storage device 12.

Subsequently, in the next step S70, if the heights of the start point and the end point are different, the flow proceeds to step S71, and if the heights of the start point and the end point are the same, the flow proceeds to step S72. That is, the beam B passes through the determined point, and the difference between the heights of the start point and the end point of the line segment that blocks the arrangement area in the arrangement direction.
The roof beams are distinguished from each other. In the case of the beam B, the heights of the line start and end points are different on the roof surface (see FIG. 26).
The case where the roof beam is used is the case where the heights of the start and end points of the line segment are the same on the roof surface (see FIG. 27).

In step S71, the beam B is registered in the database (D / B) of the auxiliary storage device 12, and the process returns to step S65 to repeat the above processing. The B beam is registered in the database in accordance with the flowchart of FIG. In step S72, the roof beams are similarly stored in the auxiliary storage device 12.
And then returns to step S65 to repeat the above processing. The registration of the roof beams in the database is performed according to the flowchart of FIG.

FIG. 41 shows an example of a method of arranging the space so as not to exceed the maximum span of the purlin when the arrangement interval exceeds the maximum span of the purlin. In this way, for example, in the section A, When the arrangement interval of the B beams 63 exceeds the maximum span of the purlin (see FIG. 17), the B beams 66 are further arranged so as not to exceed the maximum span of the purlin.

Next, with reference to the flowcharts of FIGS. 42 and 43, a description will be given of a method of registering a purlin (small beam) by the allocating device in the database (D / B) along the purlin line. In this process, the specific contents of step S6 in the flowchart of FIG. 16 are performed.
The main house (small beam) is arranged in the small beam arrangement direction along the main house line or the wife wall line in the arrangement closed area.

First, step S81 (note that step S81
42 is searched for the purlin line and the wife wall in the arrangement area. The purlin line and wife wall in this arrangement area are searched, for example, as shown in FIG. That is, in FIG. 44, the portion surrounded by the solid line is the arrangement area A, the dotted line is the purlin line, and in this case, it is assumed that purlin lines are found in this order.

In the next step S82, if there is still a purlin line or wall, the process proceeds to the next step S83. If no purlin line or wall is found, the processing is continued. The process ends (see the flowchart of FIG. 43).

Subsequently, in step S83, the dependent axes of the purlin line and the wife wall are checked. The retrieved purlin line or dependent axis of the wife wall is checked, for example, as shown in FIG. That is, in FIG. 45, similarly to FIG. 44, the part surrounded by the solid line is the arrangement area A, the dotted line is the purlin line, and the arrow indicates the small beam arrangement direction. In this case, the purlin arrangement candidate line is Minutes.

In the next step S84, if the direction of the small beams is different from the direction of the purlin line and the end wall, the flow returns to step S81 to repeat the above processing.
If the girder arrangement direction is the same as that of the purlin line and wife wall,
Proceed to the next step S85.

Subsequently, in step S85, an intersection between the purlin line or the wall and the girder is obtained. The intersection of the purlin line or the wall and the girder is obtained, for example, as shown in FIG. That is, in FIG. 46, reference numeral 71 denotes an arrangement area A, 72 denotes a purlin line, 73 denotes a girder, and 74 denotes an intersection. In this way, for example, three girder 7 parallel to one purlin line 72 are provided.
Intersections 74, 74, 74 with 3, 73, 73 are obtained.

Subsequently, in a step S86, it is checked whether or not the starting point of the purlin line or the wife wall is included in the intersection. FIGS. 47 (a) and 47 (b) show a case where the end point of the purlin line or the end wall is not included in the intersection.
Similarly to 6, reference numeral 71 denotes an arrangement area A, 72 denotes a purlin line, and 73 denotes a girder.

Then, in the next step S87, when the starting point of the purlin line or the wife wall is not included in the intersection, the process proceeds to step S88, and the main house line or the wife wall is not included in the intersection. If the start point has been entered, the process proceeds to step S89.

First, in step S88, the starting point of the purlin line or the wife wall is added to the intersection, and then in step S81.
And the above processing is repeated. Step S89
Then, it is checked whether the purlin line or the end point of the wife wall is included in the intersection (see FIGS. 47A and 47B).

Then, in the next step S90, if the purlin line or the end point of the wife wall is not included in the intersection, the process proceeds to step S91, and the purlin line or the wife wall is included in the intersection. If the end point has been entered, the process proceeds to step S92.

First, in step S91, the end point of the purlin line or the end wall is added to the intersection, and then the process proceeds to step S81.
And the above processing is repeated. Step S92
Now, sort the intersections in ascending order.

In the next step S101 (hereinafter, the flowchart of FIG. 43), if there is an intersection, the process proceeds to the next step S102, and if there is no intersection, the process ends.

Subsequently, in step S102, the current intersection and the next intersection are set as end points of the purlin. That is, for example, as shown in FIGS. 48A and 48B, in the same relationship between the arrangement area A71, the purlin line 72, the girder 73, and the intersection 74 as in FIG. Are the end points of the purlins (small beams) 75, 75.

Then, in the next step S103,
If the length of the purlin (small beam) is not more than 455 mm (for example, 1/4 module), the process returns to the step S101 and the above processing is repeated.
If it exceeds mm, the process proceeds to the next step S104.

Subsequently, in step S104, the current intersection point and the next intersection point are registered in the database (D / B) of the auxiliary storage device 12 as end points of the main house (beam). Subsequently, in step S105, the gradient of the roof surface is determined. The slope of the roof surface is stored in the auxiliary storage device 12 in advance as described above. Subsequently, in step S106, the height of the joint girder is determined from the slope of the roof surface. This combining digit is
It is a girder member having a triangular cross section interposed between a hut beam that fits vertically and a slope of the roof surface that is perpendicular to the beam, and in the same manner as described above, the auxiliary storage device 12 is associated with the slope of the roof surface in advance. It is remembered.

Subsequently, in step S107, the height obtained by subtracting the connecting girder from the end point of the purlin (small beam) is used as the purlin (small beam).
Is registered in the database of the auxiliary storage device 12 as the height of the start point and the end point. Then, in the next step S108,
After the fit (vertical fit) is similarly registered in the database (the fit of the purlin (small beam) is only "vertical"), the process returns to step S101 to repeat the above processing.

[0129] By allocating the hut beam B to the roof surface as described above, for example, in the design of the composite ridge roof shown in Fig. 2, as shown in Figs. 2,2, ..., 3,3,3, ... (roof beam 2,
B beam 3 (climbing beam 3a, climbing beam 3b)) and small beam 4,
4, 4,... Can be efficiently and automatically assigned. The shed beams B support the joints and intermediate portions of the roof panels P, P, P,... Also having the appropriate shapes and sizes automatically and automatically allocated, as shown in FIG. can do.

Thus, on the CAD system,
Since the hut beam and the roof panel assigned to the roof can be appropriately selected, the product code for ordering the hut beam and the roof panel assigned from the data of the hut beam and the roof panel as the members stored in the auxiliary storage device 12. No. By searching for the price and unit price, it is possible to create a quote for the roof portion and an order for the hut beam and the roof panel. Although the roof panel is assigned on the plan view, an actual roof panel having a corresponding shape is selected from the shape of the roof panel on the plan view and the slope of the roof.

According to the allocating apparatus having the above-described configuration, the arithmetic processing unit 11 (reference line creating means) is arranged in a plan view.
On the upper roof surface, the permissible value read from the auxiliary storage device 12.
Alternatively, for each maximum length of roof panel being manufactured,
Create a main purlin line, and create a candidate purlin line for each allowable value.
Since the main roof line (the relative main roof line and the candidate main roof line) as a reference when arranging the hut beam and the roof panel on the roof having the sloping roof surface, on the plan view, the strength of the roof, It may construct in consideration of the relationship between the length of the inclined direction of the length and the roof panel of the roof.

Can be created. In addition, the hut beam and the roof panel can be efficiently allocated based on the created relative purlin line and the candidate purlin line. Therefore, it is possible to efficiently allocate the shed beams and roof panels on the plan view while guaranteeing the strength of the roof, and it is easier to allocate roof panels on the roof slope as before.

Can be attached.

Further, even in the case of a complicated roof having a valley corner, the absolute purlin line is created, and the whole or a part of the roof surface is divided into upper and lower parts, and the roof panels are laid out. The roof panel of the simple shape can be replaced with the roof line of a simple shape by the absolute purlin line, and the roof panels can be easily allocated. Furthermore, by limiting the length of the absolute purlin line with the extension line of the ridge line or the auxiliary line, it is possible to easily allocate the roof panel, and it is possible to preferentially allocate a relatively large roof panel. Become.

Since relatively large roof panels can be allocated to the roof surface, the production of small roof panels with low production efficiency is reduced at the roof panel production site, and the ratio of large roof panels with high production efficiency is increased. Therefore, the production efficiency of the roof panel can be increased. In addition, since a relatively large roof panel is allocated, the number of roof panels allocated to the roof surface can be reduced, and the work of joining the roof panels at a building site can be saved.

As described above, according to the allocating apparatus of this embodiment, the production efficiency in the production of the roof panel from the production of the roof panel can be improved, so that the production cost of the house can be reduced.

In the above embodiment, various types of roofs have been described. However, the present invention is not limited to this, and can be applied to other complicated types of roofs. In addition, the configuration of the panel and the hut beam and the like are also arbitrary, and it goes without saying that the specific detailed structure and the like can be appropriately changed.

It is possible to efficiently and automatically allocate a hut beam that supports a joint portion and an intermediate portion of a roof panel arranged on a surface. In addition, the reference line creating means is configured to use the roof surface on the plan view.
