In Patent Document 1, the object of this patent document is to provide a roofing structure that simplifies the process of adjusting the tiles in the ridge or valley of the roof. A roofing structure in which main tiles 1 are laid in, for example, a houndstooth pattern on a roof having a certain inclination angle in order to simplify the process of adjusting the tiles in the ridge or valley of the roof. Proposal to set the ratio (X':Y) of the lateral dimension to the longitudinal direction of the working width when projected onto the horizontal plane of the installed main tile 1 so as to be an integral multiple (eg 1:2). is done.
The ratio of the working width to the vertical dimension of the working width when tiles are laid in multiple stages along the flow direction of a roof with a certain inclination angle and the laid tiles are projected on a horizontal plane. is set to be an integral multiple of 2 or more. The roof tiles are laid laterally shifted from the upper or lower roof tiles by the vertical dimension of the working width when projected onto the horizontal plane.
If the slope angles of the adjacent slopes of the roof are the same, the slope angle of the ridge or valley when projected onto the horizontal plane is an angle of 45 degrees with respect to the eaves line. Therefore, the ratio of the working width of the roof tile in the horizontal direction to the vertical direction when projected onto the horizontal plane should be an integral multiple of 2 or more (for example, length:width is 1:2, 1:3, 1:4, etc.). By setting so as to be such that the shape of the roof tiles (corner roof tiles) laid adjacent to one of the descending ridges or valleys is the same for each step.
If the ratio of vertical and horizontal dimensions is 1:2, it is sufficient to cut only two types of corner tiles during construction. It suffices to cut the corner tiles of different types, and if the ratio of vertical and horizontal dimensions is 1:4, it is sufficient to cut four types of corner tiles during construction.
That is, since it is not necessary to cut the corner tiles for all stages as in the case of construction using conventional roof tiles, the construction work can be simplified accordingly.

However, the roof material of Patent Document 1 can reduce the number of types of cutting shapes for the corner tiles of the corner ridge and the valley tiles of the valley, and can reduce the cutting work, but it is necessary to cut according to the roof shape at the site. It was necessary to do the work.
In addition, the shape of the corner tile is different between the corner ridge at the beginning of roofing and the corner ridge at the end of roofing, so it was necessary to process the corner tiles on site according to the shape of the roof at the site.
Furthermore, since the construction work in the flow direction has not been simplified, the roof material must be processed according to the shape of the roof at the site, and the problem that it takes time to construct the roof material at the landside remains. remained.

In Patent Document 2, the roof is stylized so that the shape of the corner ridge tiles of the zigzag roof is almost the same over the entire roof, and the roof slope is adjusted so that the horizontal projection dimension of the dominant foot is 5/6 of the dominant width. By making it possible to adjust the overlapping dimensions, it is possible to use roof tiles that do not differ greatly in size from commonly used flat roof tiles.
The dimension of the eaves edge L1 excluding the side tiles 3, 3a at both ends is a multiple of 1/3 of the width W of the flat tiles 1, 1a, and the width of the flat roof tiles 1, 1a, ... in the roofing state. The flat tiles 1 are formed between the side tiles 3, 3a on both sides and the flat tiles 1, 1a, . . . , 1a . 2, 2a will be roofed. Therefore, the flat tiles 1, 1a, . The effect is that a tiled roof can be constructed without using tiles.

However, the roof material of Patent Document 2 is a flat plate tile that approximates a square, and the number of roof tiles to be installed increases in the direction of the girder.
In addition, Patent Document 2 is a technique that simplifies construction by using side tiles instead of using tiles that are divided into triangles at corner ridges in the girder direction. settings are not taken into account. Therefore, the construction of the corner ridge can be simplified by using tiles. The problem still remained.
Furthermore, in hipped roofs, there are many roof shapes with valleys other than simple hipped roofs with only a corner ridge and a land ridge, such as a hipped roof where a land ridge, a corner ridge and a valley intersect, or two land ridges. Since there are countless allocation patterns due to the combination of the girder direction and the flow direction, it is necessary to match the processing shape on site and process the roofing materials on site. It is constructed by On-site processing of roofing materials that ensure proper rain protection performance requires a high level of craftsmanship, and the processing of roofing materials is time-consuming.

In Patent Document 3, the tile main body (working surface) is a square whose length is approximately equal to an integer fraction (module) of the unit dimension of the building when projected onto the horizontal plane. If an integral number of tile bodies are laid out side by side, the unit size of the building will almost match. The pillars of the building are set according to the unit size, and the ridges and corner ridges pass through these pillars. 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. Becomes the main body. Also, when roofing between the corner ridge and the valley, it is necessary to open the valley by the length of the half tile body, so if the first tile is the tile body (or the half tile body) The last tile becomes the half tile body (or tile body). Also, when roofing between valleys, 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 will be the half tile body. In this way, the effect is exhibited that the tiles can be laid out very easily.

However, the roof material of Patent Document 3 has a square shape with one side having a length approximately equal to an integer fraction (module) of the unit dimension of the building, and it is necessary to arrange many roof materials in order to allocate it to the roof surface. There was a problem that it took time and effort to construct the roof material.
At the end of the hipped roof near the ridge, tiles such as the three-pronged part and the ridge-curved part are fitted. There was a problem that it was difficult to process the roof tiles in this area, and it took a lot of time and effort to do it on site.
In addition, in the method of arranging tiles, a rule was required to alternately arrange the tile main body and half tiles by skipping one step in the flow direction. .
Furthermore, it is necessary to set not only pantiles but also a large number of dedicated tiles such as double pantiles, half tiles, double pan half tiles, valley tiles, valley tiles with side connections, and surrounding corner tiles, and it is not a multi-kind small lot production system. There were problems such as poor production efficiency due to the inability to produce and an increase in inventory burden due to the need to manage inventory of many items.

The present invention relates to a roof of a building having a sloped roof, the roof having a corner ridge or a valley, a plurality of roof materials arranged in a girder direction, and a plurality of roof materials arranged in a tier direction. , the horizontal projection dimension of the working length of the roof material is an integer fraction of the design unit dimension of the building, and the working width dimension of the roof material is an integral multiple of two or more times the horizontal projection dimension of the working length. When arranging the roof materials step by step in the flow direction from the eaves toward the land ridge, the roof materials are arranged from one end to the other end with respect to the girder direction of the roof surface to be arranged. The working width of the roof material used for adjusting the girder direction on the roof surface is the horizontal distance of the working length of the roof material. It is an integer multiple of the projected dimension, and by placing the adjustment roof material instead of the roof material, the dimension in the girder direction is adjusted according to the difference in the working width dimension, and the positioning is performed under the dimension conditions in both the stream direction and the girder direction. All roof ends such as three-forked parts, hipped ridge parts, land ridge curved parts, land ridge parts, wall edge parts, corner ridge parts, valley parts, etc. that are positioned according to the dimensional conditions in either the stream direction or the girder direction. A roof edge standardized shape roof material standardized with a central slope within a predetermined standardized slope range is placed on all roof edges of the and the adjustment gap width is wider than the gradient shape adjustment range width.

The method for arranging long horizontal modular roofing materials according to claim 1 of the present invention is a roof of a building having a sloped roof, the roof having a corner ridge or a valley, and the roofing materials being girders. In a roof in which a plurality of roof materials are arranged in a direction and a plurality of roof materials are arranged in a tier direction, the horizontal projection dimension of the working length of the roof material is an integral fraction of the design unit dimension of the building, and the function of the roof material The width dimension is an integral multiple of two or more times the horizontal projection dimension of the working length, and when the roof materials are arranged step by step in the flow direction from the eaves toward the land ridge, the roof materials are arranged on the roof. It is used to adjust the dimension of the roof surface in the girder direction by shifting the integral multiple of the horizontal projection dimension of the working length of the roof material from one end to the other end with respect to the girder direction of the surface. The working width dimension of the adjustable roof material is an integral multiple of the horizontal projection dimension of the working length of the roof material. All roof ends such as three-forked parts, hipped ridges, land ridge bends, etc., and either the stream direction or the girder direction At all roof ends, such as land ridges, wall edges, corner ridges, valleys, etc., which are positioned according to the dimension conditions, standardized shape roof materials for roof ends standardized with a central slope within the specified standardized slope range are placed. , the roof edge standardized shape roof material and the corner ridge are separated by an adjustment gap width, and the adjustment gap width is wider than the gradient shape adjustment range width.

According to the present invention, the roof of a building has a sloped roof, the roof has a corner ridge or a valley, a plurality of roof materials are arranged in a girder direction, and a plurality of roof materials are arranged in a tier direction. In the roof, the horizontal projection dimension of the working length of the roof material is an integer fraction of the design unit dimension of the building, and the working width dimension of the roof material is twice or more the horizontal projection dimension of the working length. It is an integral multiple, and when the roof materials are arranged step by step in the flow direction from the eaves toward the land ridge, the roof materials are arranged from one end to the other end in the girder direction of the roof surface to be arranged. The working width of the adjusting roof material used for adjusting the dimensions in the girder direction on the roof surface is the working length of the roof material. is an integral multiple of the horizontal projection dimension of the roof material, and by arranging the adjustment roof material instead of the roof material, the dimension adjustment in the girder direction is performed by the difference in the working width dimension, and the dimension conditions in both the stream direction and the girder direction All roof ends such as three-forked parts, hipped ridges, and land ridge bends that are positioned with , and land ridges, wall edges, corner ridges, and valleys that are positioned under either the flow direction or the girder direction. A standardized shape roof material standardized at the central slope of a predetermined standardized slope range is placed on all roof ends such as the corners, and the standardized shape roof material and corner ridge are adjusted. It is possible to arrange the roofing materials in conjunction with the design unit size of the building by separating by the gap width and the adjustment gap width being wider than the slope shape adjustment range width. It is possible to arrange the standardized shape roof materials for all the roof ends, such as the three-pronged part, the different hipped part, and the curved part of the flat roof, which have been processed.
In addition, the standardized shape of the roof edge can be arranged at all the roof edge portions such as the land ridge portion, corner ridge portion, verge portion, wall edge portion, valley portion, and the like.
In other words, it is possible to arrange standardized roof-end-shaped roof materials on all roof ends.
As a result, all roof edges are matched on-site, eliminating the need to process roof materials on-site. As a result, it becomes possible to carry out construction work that guarantees appropriate rain protection performance even if it is not a highly skilled craftsman, and the productivity at the construction site can be greatly improved.
These effects can solve the problem of shortage of craftsmen, which is a serious problem in the construction industry.
Since the standardized shape roof material for the roof end is standardized at the central slope of the predetermined standardized slope range, it is not necessary to set the standardized shape roof material for the roof end for each slope. In order to set the standardized shape roof material for the roof end with one shape for one roof end part within the standardized slope range, it is possible to easily manage the product number of multiple types of standardized shape roof materials for the roof end. It will be possible.
Product number management enables production management and inventory management, and it is possible to inventory standardized shape roof materials for each roof edge. Roofing work can be done simply by delivering roofing materials with a standardized shape to the roof ends and placing them on the roof.
When the roof shape is horizontally projected, the corner ridge and valley are always set to 45 degrees when one girder direction is set to 0 degrees. The horizontal projection dimension of the working length of is shifted in the girder direction. Taking advantage of this fact, the working width of the roof material should be an integral multiple of at least two times the horizontal projection of the working length, and when the roof material is arranged in the girder direction, the working length of the roof material should be horizontal. By adopting an arrangement rule in which each stage is shifted by an integer multiple of the projection dimension, the arrangement rule in each stage is also simple, clear, and easy to understand, and the types of standardized roof materials at the roof edge can be reduced.
In addition, by lengthening the roof material, the workability can be improved by reducing the number of roof materials to be installed in the horizontal direction.

Hereinafter, a method of arranging long horizontal modular roofing materials according to an embodiment of the present invention will be described.
FIG. 1 is a roof material allocation diagram for a hipped roof according to an embodiment.
FIG. 1(a) is a layout diagram of roof materials 1 assuming an actual roof 2 in a hipped roof.
FIG. 1(b) is a layout drawing enlarging the enlarged range of the hipped ridge difference portion shown surrounded by a square line in FIG. It is the figure which described the top view of the square-shaped roof material 10 in the layout drawing.
FIG. 1 shows a roof 2 of a building comprising a roof 2 with a slope 21, said roof 2 being a hipped roof with a corner ridge 3 and a valley 4. FIG.
It is a roof 2 in which a plurality of roof materials 1 are arranged in a girder direction 7 and a plurality of roof materials 1 are arranged in a step direction, the horizontal projection dimension Lh of the working length of the roof material 1 is 227.5 mm, The design unit dimension P of the shaku module is 910 mm.
The horizontal projected dimension Lh of the working length of the roof material 1 is a quarter of the design unit dimension P of the building.
The working width dimension W of the roofing material 1 is 1820 mm, and the horizontal projection dimension Lh of the working length is 227.5 mm, so the relationship is eightfold.
When the roof material 1 is arranged step by step in the flow direction 8 from the eaves 5 toward the land ridge 6, the roof material 1 is arranged from one end to the other with respect to the girder direction 7 of the roof surface to be arranged. The working length of the roof material 1 is shifted in the direction of the end portion by one times the horizontal projection dimension Lh.
The working width dimension of the adjustment roof material 11 used for the dimension adjustment in the girder direction 7 on the roof surface is an integral multiple of the horizontal projection dimension Lh of the working length of the roof material 1. In FIG. Two types of adjustable roofing materials 11 having double working widths of 455 mm and 910 mm are used.
By arranging the two types of adjustment roof materials 11 in place of the roof material 1, the dimension in the girder direction 7 is adjusted according to the difference in working width between the roof material 1 and the adjustment roof material 11.
In the case of a triangular or trapezoidal roof surface with corner ridges 3 on both sides of the hipped roof, the length of the roof surface in the girder direction 7 is the horizontal projection dimension Lh of the working length of the roof material 1 on one side of each tier, and on both sides Since the length in the girder direction 7 is shortened by twice the horizontal projection dimension Lh of the working length of the roof material 1, in FIG. Each time, the length dimension in the girder direction 7 is shortened by 455 mm.
Therefore, the length in the girder direction 7 varies from 455 mm to 1820 mm for each stage in multiples of 455 mm.
In the embodiment of FIG. 1(a), when the adjustment dimension in the girder direction 7 is 455 mm, the adjustment roof material 11 with a working width of 455 mm is arranged, and when the adjustment dimension is 910 mm, the adjustment roof material 11 with a working width of 910 mm is arranged. In the case of 1365 mm, the adjustment roof material 11 with a working width dimension of 455 mm and the adjustment roof material 11 with a working width dimension of 910 mm are arranged, and in the case of 1820 mm, the roof material 1 with a working width dimension W of 1820 mm is arranged. Adjust the dimensions of
In addition, it is also possible to adjust the size by arranging a plurality of 455 mm adjusting roof materials 11 .
In this case, although the number of construction roof materials 11 increases, the types of working width dimensions of the adjustment roof materials 11 can be reduced.

In FIG. 1, the roof end portions 9 such as the three-forked portion 9d, the hipped ridge portion 9g, and the land ridge curved portion 9f, which are positioned under the dimensional conditions in both the stream direction 8 and the girder direction 7, are provided with respective roof end portions. A standardized shape roofing material 10 is placed.

However, setting the standardized roof material 10 for each slope 21 is not desirable in terms of productivity, product number management, and inventory management of the standardized roof material 10. Therefore, in the present invention, the roof The shape of the edge standardized shape roofing material 10 is summarized.
A normalized gradient range is set as the gradient range to which the arrangement method of the present invention is applied, and the amount of shape change at the upper and lower slopes in the normalized gradient range is grasped. By setting the central slope of the standardized slope range to be a value and standardizing with the shape of the standardized roof materials 10 at the central slope, the standardized roof materials 10 are collected.
The roof end standardized shape roof material 10 having a shape standardized by the central slope of the standardized slope range is arranged at each roof end 9 .
The roof edge standardized shape roof material 10 arranged at the roof edge 9 near the corner ridge and the corner ridge 3 are separated by the adjustment gap width CW.

A roofing material 11 and an adjustable roofing material 11 having a working width of 910 mm are arranged.
After the fifth stage, the roofing material 1 is arranged by repeating this process.
