Japanese Unexamined Patent Publication No. 8-109708

In Patent Document 1, the roof tile main body (working surface) is a square whose one side is a length whose projected shape on the horizontal plane when thatched is approximately equal to an integral fraction (module) of the unit dimension of the building. When an integer number of roof tiles are lined up and thatched, they almost match the unit dimensions of the building. Then, the pillars of the building are provided according to the unit dimensions, the valleys and corner ridges pass through these pillars, and the projected shape on the horizontal plane is provided along the slope line inclined by 45 ° from the wall surface. When roofing between the roof and the corner ridge, if the first tile is the tile body, the last tile will be the tile body, and if the first tile is the half tile body, the last tile will be the half tile. It becomes the main body. Also, when roofing between the corner ridge and the valley, it is necessary to open the valley part by the length of the half-tile body, so if the first tile is the tile body (or half-tile body) The last tile becomes the half-tile body (or tile body). Also, when roofing between valleys, only the length of the half-tile body is opened in both valleys, so if the first tile is the tile body, the last tile will be the tile body. If the first tile is the half-tile body, the last tile is the half-tile body. In this way, the effect of allocating roof tiles is extremely easy.

Hereinafter, a method of arranging the roofing material of the long horizontal roofing module roofing material according to the embodiment of the present invention will be described.
FIG. 1 is a roof material allocation diagram for a hipped gable mixed roof according to an embodiment.
FIG. 1 shows a roof 2 of a building having a sloped roof 2, and the roof 2 is a hipped gable mixed roof in which a hipped roof having a corner building 3 and a valley 4 and a gable roof having a keraba portion 9c are mixed. It is a roofing material allocation diagram in a roof.
FIG. 1 (a) shows a roof allocation diagram of a second-floor roof in a hipped gable mixed roof, and FIG. 1 (b) shows a roof allocation diagram of a first-floor roof of the same hipped gable mixed roof.
The design unit dimension P of the building is a shaku module, and the design unit dimension P is 910 mm.
The horizontal projection dimension Lh of the working length of the roofing material 1 is 455 mm, which is half of the design unit dimension P of the building, and the working width dimension W of the roofing material 1 is four times the horizontal projection dimension Lh of the working length. It is set to 1820 mm, which corresponds to this.
First, a method of arranging the trapezoidal roof surface shown on the lower side of FIG. 1A will be described.
The arrangement direction of the roofing material 1 is the direction from the right corner ridge portion 9b to the left corner ridge portion 9b with respect to the girder direction 7 of the roof surface.
A corner ridge standardized shape roofing material 10b is arranged in the corner ridge portion 9b.
The working width dimension of the corner ridge standardized shape roofing material 10b is 910 mm, which is half of the working width dimension W of the roofing material 1.
The working width dimension of the right corner ridge standardized shape roofing material 10b and the left corner ridge standardized shape roofing material 10b is the same 910 mm.
The right corner ridge standardized shape roofing material 10b is arranged in the right corner ridge portion 9b, the roofing material 1 is arranged on the left side thereof, and the roofing material 1 is sequentially arranged toward the left corner ridge portion 9b.
In FIG. 1A, the eaves girder size of the trapezoidal surface is 9100 mm, which is 10P in terms of the design unit size.
Further, since the eaves protrusion dimension 12 is 910 mm, the dimension at the tip of the roofing material from the right corner ridge 9b to the left corner ridge 9b of the first stage of the eaves is 10920 mm, which corresponds to 12P.
Since the working width dimension W of the roofing material 1 is 1820 mm, which corresponds to 2P, and the corner ridge standardized shape roofing material 10b is 1P, which is half of that, the working width dimension of the left and right corner ridge standardized shape roofing material 10b is 2P. ..
Five roofing materials 1 make 10P, and when the corner ridge standardized shape roofing materials 10b are arranged on the left and right, it becomes 2P. Therefore, when all of them are combined, it becomes 12P, which can be arranged symmetrically and neatly.

After the roofing material 1 is arranged on the first stage, the roofing material 1 is arranged on the second stage.
In the second stage, as in the first stage, the corner ridge standardized shape roofing material 10b having the same shape as the first stage is arranged in the right corner ridge portion 9b, and the roofing material 1 is arranged on the left side thereof.
The position of the second-stage roofing material 1 with respect to the first-stage roofing material 1 is shifted to the left side in the girder direction 7 by 455 mm, which is the horizontal projection dimension Lh of the working length of the roofing material 1.
The roofing material 1 is sequentially arranged toward the left corner ridge portion 9b, and the corner ridge standardized shape roofing material 10b having the same shape as the first stage is arranged on the left corner ridge portion 9b.
In the second stage, the dimension of the girder direction 7 at the tip of the roofing material is 455 mm shorter on the right side and 455 mm shorter on the left side than the first stage, so that the total length of the left and right sides is 910 mm, which is 1 P shorter.
The dimension of the second stage girder direction 7 is 11P, which is obtained by subtracting 1P from the 1st stage dimension of 12P. Since the corner ridge standardized shape roofing material 10b is arranged on each side of the 1P, the roofing material 1 is placed in the space of 9P. Will be placed.
Since the working width dimension W of the roofing material 1 is 2P, the space is equivalent to 4.5 sheets, and the adjusting roofing material 11 of 910 mm, which is the working width dimension of 0.5 sheets of the working width dimension W of the roofing material 1, is placed in the left corner. By arranging one sheet on the right side of the building standardized shape roofing material 10b, the dimension is 7 in the girder direction of 11P, and the second stage can be assigned.

When adjusting the dimensions of the girder direction 7 on the roof surface as in the second step of the trapezoidal surface in FIG. 1A, the adjusting roofing material 11 is arranged.
The dimension of the girder direction 7 on the roof surface is shortened by the horizontal projection dimension Lh of the working length of the roofing material 1 on one side in the corner ridge portion 9b.
When there are corner ridges 3 on the left and right sides of the girder direction 7, the working length of the roofing material 1 is shortened by twice the horizontal projection dimension Lh on the left and right sides.
The working width dimension W of the roofing material 1 is 1820 mm, which is four times the horizontal projection dimension Lh of the working length of the roofing material 1, so the horizontal projection dimension Lh of the working length of the roofing material 1 in the girder direction 7 for each step. The fact that the dimension is twice as short as that of the adjustment roofing material 11 means that the working width dimension of the adjusting roofing material 11 is set to twice the horizontal projection dimension Lh of the working length of the roofing material 1 in the girder direction 7 of the adjusting roofing material 11. The adjustment dimension matches the dimension in the girder direction 7 where the adjustment dimension is shortened step by step.
By setting the working width dimension of the adjusting roofing material 11 to 910 mm, which is twice the horizontal projection dimension Lh of the working length of the roofing material 1, the working width dimension W of the roofing material 1 is 1820 mm, and the working width of the adjusting roofing material 11 Since the dimension is 910 mm, 910 mm, which is the difference between the working width dimension W of the roofing material 1 and the working width dimension of the adjusting roofing material 11, functions as the adjusting dimension in the girder direction 7.

The roof surface on the left side of FIG. 1A is a roof surface of a hipped gable mixed roof having a corner ridge portion 9b on the right side and a keraba portion 9c on the left side when viewed from the girder direction 7.
On this roof surface, since the corner ridge 3 is only on the right side, the dimensional difference between the first and second girder directions 7 is one times the horizontal projection dimension Lh of the working length of the roofing material 1.
On the roof surface where the corner ridge 3 exists only on one side, the working width dimension of the adjusting roofing material 11 is an integral multiple of one or more times the horizontal projection dimension Lh of the working length of the roofing material 1.
In FIG. 1A, there is a corner ridge portion 9b on one side and a keraba portion 9c on the other side, and the working width dimension W of the roofing material 1 is four times the horizontal projection dimension Lh of the working length of the roofing material 1. In the case of the roof surface, the working width dimension of the adjusting roofing material 11 needs to be three types of one, two, and three times the horizontal projection dimension Lh of the working length of the roofing material 1.
However, in FIG. 1A, allocation is performed only by the adjusting roofing material 11 having two types of working width dimensions, 455 mm, which is once the horizontal projection dimension Lh of the working length of the roofing material 1, and 910 mm, which is twice the working length. There is.
Specifically, two sheets of 1x 455mm and 2x 910mm are used for the steps that require the adjusting roofing material 11 with 3 times the working width dimension, and 3 times by combining a plurality of adjusting roofing materials 11. The dimension of 1365 mm is adjusted.

The arrangement of the roofing material 1 and the adjusting roofing material 11 on the third and fourth stages of the trapezoidal surface of FIG. 1A is the same as the arrangement of the first and second stages, and the adjusting roofing material 11 is inserted in the third stage. The adjustment roofing material 11 is placed in the fourth stage.
In the third stage, the corner ridge standardized shape roofing material 10b is arranged in the left and right corner ridges 9b, and four roofing materials 1 are arranged in the space between them.
In the fourth stage, the corner ridge standardized shape roofing material 10b is arranged in the left and right corner ridges 9b, three roofing materials 1 are arranged in the space between them, and the space is adjusted to 0.5 sheets of the roofing material 1. One roofing material 11 is arranged.

The roof 2 of FIG. 1A has two land ridges 6 and is orthogonal to each other at a bent portion of 9 g.
The two land buildings 6 have the same height, and the flow lengths of the five roof surfaces are all the same.
The horizontal projection dimension of the flow length of the roof surface is 2730 mm, which is half of 5460 mm from the land ridge 6 to the eaves girder, 910 mm from the eaves girder to the eaves tip 5, and the horizontal projection of the flow length from the eaves 5 to the ridge. The dimension is 3640 mm, which is 4P in terms of the design unit dimension P of the building.
Since the horizontal projection dimension Lh of the working length of the roofing material 1 of the land building portion 9a is 455 mm, it is possible to calculate that the number of flow steps is 8 by dividing the horizontal projection dimension 3640 mm of the flow length by 455 mm for one step. You can.

In the arrangement of the roofing material 1 and the adjusting roofing material 11 on the trapezoidal surface of FIG. 1A, the odd-numbered first, third, fifth, and seventh steps are allotted only to the roofing material 1, and are even. The second, fourth, and sixth steps, which are steps, are arranged by the roofing material 1 and the adjusting roofing material 11.
On the 8th stage of the uppermost stage near the land building, a land building standardized shape roofing material 10a having a shape in which the roofing material 1 and the adjusting roofing material 11 flow from the tail side and are cut short by a dimension of 13 minutes is arranged.

The triangular surface located on the right side of the trapezoidal surface in FIG. 1A has basically the same arrangement of the roofing material 1 as the trapezoidal surface.
However, unlike the trapezoidal surface, the land ridge 6 does not exist in the eighth stage, so only the three-pronged standardized roofing material 10e is arranged in the three-pronged portion 9e.

In the parallelogram surface of the trapezoidal surface of FIG. 1A located on the opposite side of the land ridge 6, the corner ridge 3 and the valley 4 are located in parallel.
The method of arranging the roofing material 1 and the standardized shape roofing material 10 on the parallelogram surface is to arrange the corner ridge standardized shape roofing material 10b similar to the trapezoidal surface on the corner ridge 9b and the valley standardized shape on the valley 9f. The roofing material 10f is arranged, and the roofing material 1 is arranged between them.
When climbing one step from the eaves 5 to the land ridge 6, the roofing material 1 is projected in the direction from the corner ridge 9b to the valley 9f with respect to the girder direction 7, and the horizontal projection dimension Lh of the working length of the roofing material 1. Arrange them with a shift of 455 mm.

The roof surface having the corner ridge 3 and the keraba located on the left side of the trapezoidal surface of FIG. 1 (a) is the corner ridge 9b with respect to the girder direction 7 when climbing one step from the eaves 5 toward the land ridge 6. The roofing material 1 is arranged so as to be offset by 455 mm for the horizontal projection dimension Lh of the working length of the roofing material 1 in the direction from the ridge to the keraba portion 9c.
In the first stage, the corner ridge standardized shape roofing material 10b similar to the trapezoidal surface is arranged in the corner ridge portion 9b on the right side with respect to the girder direction 1, and the roofing material is sequentially placed in the left direction of the corner ridge standardized shape roofing material 10b. Place one.
A keraba standardized roofing material 10c having a working width of 910 mm is arranged in the keraba portion 9c.
Similarly, the corner building standardized shape roofing material 10b and the roofing material 1 are arranged in the second stage, and the keraba standardized roofing material 10c having a working width dimension of 455 mm is arranged in the keraba portion 9c.

The advantage is that the placement rules in the department are easy to understand.
Further, since the left and right corner ridge standardized shape roofing materials 10b are 910 mm, which is half of the working width dimension W of the roofing material 1, the left and right corner ridge standardized shape roofing materials 10b can be precut. There is also an advantage that the production efficiency of the corner ridge standardized shape roofing material 10b is high.
However, there are disadvantages that the arrangement rule becomes complicated by arranging three types of the adjusting roofing material 11 and that the number of types does not decrease so much because three types of the adjusting roofing material 11 are added.

This arrangement method can reduce the types of the standardized shape roof material 10 of the roof end portion 9 to 5 types, reduce the adjustment roof material 11 to 2 types, and standardize the corner ridge portion 9b. Since there is only one type of roofing material 10b, there is an advantage that the arrangement rules in the corner ridges can be easily understood.
Further, since the left and right corner ridge standardized shape roofing materials 10b are 910 mm, which is half of the working width dimension W of the roofing material 1, the left and right corner ridge standardized shape roofing materials 10b can be precut. There is also an advantage that the production efficiency of the corner ridge standardized shape roofing material 10b is high.
However, there is a demerit that two types of adjusting roofing materials 11 are arranged and three types of dimensional adjustments can be made by combining the adjusting roofing materials 11, which complicates the arrangement rules.
