Description

TECHNICAL FIELD The present invention relates to a metal roof plate for a sled roof used for thatching of roofs of buildings such as shrines and temples having sled roofs.

2. Description of the Related Art In general, a roof of a building is required to have a strong, beautiful roof that is light, does not break, and a metal plate roof has been conventionally known as a material that satisfies this requirement. In a conventional roof with a metal plate, a large number of long roof plates having arcuate rising connection portions on both left and right sides of a flat valley portion are connected in parallel so that the flat valley portion and the cylindrical connecting portion are separated from each other. It is what is called a so-called cylindrical thatched roof that is formed alternately (see, for example, Japanese Utility Model Publication No. 56-45942), and this conventional cylindrical thatched roof shows the beauty of Japanese traditional roofs by using metal roofing boards. It was designed by taking full advantage of the characteristics of the, and matched the roof of a Japanese style building.

Problems to be solved by the invention By the way, as traditional roofs of Japanese-style buildings in Japan, sled roofs at shrines, temples, etc. are known. , Considered to be used for making sled roofs of buildings such as shrines and temples. In order to form such a sled roof, it is rather necessary to make the tops of the substantially cylindrical connection parts of the adjacent roof plates inward, to squeeze them, and to extend the flat valley parts of both roof plates. However, the conventional roof plate has a problem in that it is difficult to sufficiently squeeze the substantially cylindrical connecting portion, and thus it is difficult to form a sled roof having a sufficient curvature.

The purpose of this invention is to solve the above-mentioned problems of the prior art, make the most of the advantages of metal roof boards, and form a very beautiful cylindrical thatched roof that matches buildings such as shrines and temples. It is an object of the present invention to provide a metal roof plate for a sled roof, which is excellent in aesthetics because dust and dust are less likely to be deposited on the surface of the roof plate in the formed sled roof and which has sufficient durability.

Means for Solving the Problems In order to achieve the above-mentioned object, the present invention provides a flat valley portion having a required width and a substantially cylindrical connection in which left and right sides of the flat valley portion are connected and adjacent roof plates are connected to each other. A metal roof plate having a pair of arcuate rising connection parts to form a portion, wherein a large number of parallel uneven portions extending in the width direction are provided in the upper half of both left and right arcuate rising connection parts. And a metal roof plate for a sled roof in which the upper half of the arcuate rising connection has a corrugated longitudinal section, and the lower half of the left and right arcuate rising connections has a smooth surface. I am trying.

Effects According to the above-mentioned metal roof plate for a sled roof, a large number of side-by-side concavo-convex portions extending in the width direction are provided in the upper half of the arcuate rising connection portions on both sides of the flat valley portion, and the arcuate rising connection is provided. Since the upper half of the part has a corrugated longitudinal section, it is formed into a substantially cylindrical shape to form a sled roof after connecting arc-shaped rising connection parts of adjacent roof plates to each other to form a substantially cylindrical connection part. When both roof plates are bent back with the top of the connecting part inside, the arcuate rising connection part is appropriately bent along these fields of the sled roof with these uneven parts as creases, thereby forming a substantially cylindrical connection. The upper half of the upper part can be squeezed sufficiently, and the lower half of the left and right arc-shaped rising joints of the roof plate, which has a smooth surface without unevenness, and the flat valleys connected to this are sufficiently extended. Can, so 15m
As described above, it is possible to form a finished sled roof having a sufficient curvature, preferably 20 m or more.

Moreover, since the parallel uneven portions are provided in the upper half of the arc-shaped rising connection portion, and the lower half portion of the rising connection portion has a smooth surface without unevenness, the roof of the sled roof after formation is formed. On the upper surface of the plate, for example, even if dust or dust adheres to the uneven portion of the upper half portion of the arc-shaped rising connection portion, the dust or dust will not fall on the lower half portion of the rising connection portion where there is no unevenness. It quickly flows down to the flat valley connecting to this, and is discharged from the flat valley below the eaves. Therefore, it is difficult for dust and dirt to accumulate on the surface of the roof plate, and it is aesthetically pleasing. It has durability.

Embodiment Next, an embodiment of the present invention will be described with reference to the drawings.

In this specification, the upper and lower sides and the left and right sides are based on FIG. 2, the upper side means the upper side in FIG. 2, the lower side means the lower side in FIG. 2, the left side means the left side in the figure, and the right side means the right side. And
