As the material of the turning material A, metal plates (colored steel plate, aluminum plate, titanium plate, stainless plate, copper plate,
(Sandwich steel plate, clad steel plate, etc.), or synthetic resin plate, etc. formed by roll forming, press forming, etc., and as shown in FIG. 1 to FIG. It functions as a decorative material, a waterproof material, a covering material, and the like.

To explain further, the turning material A is formed into a fan shape with a generally fan shape as a whole.
6 and 5 (b), which are end views of the portion indicated by a line
The end view of the portion indicated by the line B is shown in FIG. 7 and FIG.
The end view of the portion indicated by the line C is shown in FIG. 8 and FIG.
FIG. 9 and FIG. 5 (a), which are end views of the portion indicated by the double line,
It is formed as shown in FIG. 10 which is an end view of the portion indicated by E, and is formed in a mountain shape from the apex 2 corresponding to the central portion of the decorative surface 1 in the cross section. In addition, on the long edge side which is the upper part, a locking tongue piece 3 formed by bending in a substantially U shape toward the decorative surface 1 side, and the tip of the locking tongue piece 3 is further outward in substantially parallel to the decorative surface 1. It is composed of a protruding waterproof surface 4 and a projection 5 formed so as to surround the waterproof surface 4, and is for preventing rainwater and the like from entering the inside. Further, on the short edge side which is the lower part, the stepped decorative surface 7 bent to the back surface 6 side and the stepped decorative surface 7
Is formed with an engaging tongue piece 8 whose lower end is bent substantially parallel to the decorative surface 1. Further, a goby-shaped fitting tongue piece 9 that is bent inward is formed on both left and right edges of the decorative surface 1.

The vertical cross-sectional shape of the decorative surface 1 is substantially the same as that of the decorative surface 10 of the stepped roof material B as shown in FIG. 11, and the stepped decorative surface 7 also corresponds to the step 11 of the roof material B. This creates an appropriate level difference and improves the design.

By engaging the engaging tongue piece 3 with the engaging tongue piece 8, the turning torch material A is vertically connected to prevent fluttering of the turning material A, and the engaging tongue of the upper turning material A to be engaged. The piece 8 is brought into close contact with the upper part of the decorative surface 1 of the lower thatching material A to improve waterproofness.

The waterproof surface 4 supports the decorative surface 1 at the lower end of the upper swivel material A and the decorative surface 10 of the roof material B, so that the capillaries at the connecting portion between the upper swivel material A and the roof material B are supported. By preventing the phenomenon, the waterproof property is improved and the stepped decorative surface 7 is prevented from being deformed by an external force.

Further, since the upper locking tongue piece 3 is formed by a straight line of three sides, it is possible to perform press working without making a break, and further, when the turning roofing materials A are connected to each other. A large space is formed between the engaging tongue piece 8 and the locking tongue piece 3 at the corner of the straight line, and this space prevents the capillarity phenomenon and greatly improves the waterproofness of the valley portion.

Further, as shown in FIG. 7, since the center 3a of the locking tongue piece 3 is a portion which is bent around the apex 2,

That is, if the space of the locking tongue 3 is made large so that rainwater or the like does not enter from between the turning materials A, the locking tongue 3 and the engaging tongue 9 do not rattle but engage with each other. It can be installed without rattling.

Further, the engagement tongue 9 corresponds to the slope of the roof, and its length l ₃ also changes. The larger the angle of the slope of the roof, the longer the length l ₃ and the angle of the slope. The smaller is, the shorter is the length l ₃ .
That is, as the slope angle becomes larger, the length of the valley becomes shorter. Therefore, if the length l ₃ of the engaging tongue piece 9 is short, the engaging tongue piece 3 will not engage with and will not engage with the engaging tongue piece 3, resulting in flapping, The risk of falling off is increased. Therefore, the engaging tongue 7 is previously
The length l ₃ may be formed to be a long length, and may be cut and used according to the slope of the roof at the time of factory shipment.
In this way, since only one type of the thatching material A can cope with changes in the roof slope, it is possible to reduce costs such as manufacturing equipment and costs. The turning material A can easily follow the change in θ ₁ by utilizing the elastic deformation of the material.

The backing material C shown in FIG. 12 is a long rectangular plate material, and its material is a siding board, a siding insulation board, a gypsum board, an ALC board, a concrete board, a PC board, a rock wool board. , A plywood, a foam plate such as a styrene board, a synthetic resin foam such as a urethane foam, an isocyanurate foam, a phenol foam, a vinyl chloride foam, or a composite plate made of these.
