7 and FIG. 5A, which are end views of a portion indicated by a line B,
8 and 5A, which are end views of a portion indicated by a c-line.
FIGS. 9 and 5A, which are end views of a portion indicated by a double line,
It is formed as shown in FIG. 10 which is an end view of a portion indicated by an E line, and FIG. 11 which is an end view of a portion indicated by a he-line in FIG. Is formed in the shape of a mountain from the vertex 2 corresponding to. A locking tongue piece 3 formed by bending a substantially U-shape toward the decorative surface 1 on the long edge side serving as an upper portion, and a tip of the locking tongue 3 is further outwardly substantially parallel to the decorative surface 1. A waterproof surface 4 protruding and a fixing surface 5 protruding outward in a substantially L-shape from the tip of the locking tongue 3 are formed.
A stepped decorative surface 7 bent toward the back surface 6 on the short edge side serving as a lower portion.
And an engaging tongue 8 having a lower end of the stepped decorative surface 7 bent substantially parallel to the decorative surface 1, a central portion of the engaging tongue 8 notched, and a central portion of the stepped decorative surface 7 protruding downward to cushion. The projection 7a is formed. Further, on the left and right side edges of the decorative surface 1 are formed gob-shaped fitting tongue pieces 9 bent inward.

The vertical cross-sectional shape of the decorative surface 1 is substantially the same as the shape of the wooden edge of the decorative surface 10 of the stepped roof material B as shown in FIG. 12, for example, and the step decorative surface 7 also corresponds to the step 11 of the roof material B. This creates a moderate step and improves the design.

The locking tongue piece 3 engages with the engaging tongue piece 8 to vertically connect the turning material A to prevent flapping of the turning material A, and to engage the engaging tongue of the upper turning material A. The piece 8 is in close contact with the upper part of the decorative surface 1 of the lower covering material A to improve waterproofness.

The waterproof surface 4 supports the decorative surface 1 at the lower end of the upper covering material A and the decorative surface 10 of the roofing material B, thereby forming a capillary at the connection between the upper covering material A and the roofing material B. By preventing the phenomenon, the waterproof property is improved, and the stepped decorative face 7 is prevented from being deformed by an external force. Reference numeral 4a denotes a projection for preventing rainwater or the like from entering the inside.

The fixing surface 5 is for fixing the roofing material A on the roof foundation α, and has a function like a hanger.

The upper locking tongue 3 is formed by straight lines on three sides, so that pressing can be performed without making a cut. Further, when the 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 capillary phenomenon and greatly improves the waterproofness of the valley.

Further, as shown in FIG. 7, the center 3a of the locking tongue piece 3 is a portion that can be bent around the vertex 2 so that
Only the center 3a is formed in a crushed state so as not to form much space, and the locking tongue 3 is locked by the center 3a. In other words, when the space of the locking tongue 3 is formed large so that rainwater or the like does not infiltrate from between the roofing materials A, the locking tongue 3 and the engaging tongue 8 do not rattle and engage with each other. It can be constructed without rattling.

Further, Kakarigoshitahen 8 is intended to change also the length l ₃ corresponds to the gradient of the roof, the greater the length l ₃ greater the angle of slope of the roof longer, the angle of slope The smaller the is, the shorter the length l ₃ is.
In other words, if the inclination angle is large, the length of the valley portion is short, and if the length l ₃ of the engaging tongue piece 8 is short, the engaging tongue piece 3 does not engage or lock with the locking tongue piece 3, so that the fluttering occurs. The risk of falling off and falling increases. Therefore, the engaging tongue 8
The length l ₃ may be formed to be longer, and cut and used in accordance with the inclination of the roof at the factory shipment stage.
In this way, since the roofing material A can respond to a change in roof slope with one type, costs such as manufacturing equipment and costs can be reduced. The roofing material A can easily follow the change in θ ₁ by utilizing the elastic deformation of the material.

The cushioning projection 7a has a shape in which the center of the engaging tongue piece 8 is notched, and the center of the stepped decorative surface 7 diverges from the decorative surface 1 toward the lower end and protrudes in a conical shape, or is not shown but projects. Even if the two decorative surfaces 1 are changed with the vertex 2 as a bending line in accordance with the change in the roof gradient, a cut is made in the center of the step decorative surface 7 only by changing the height of the buffer protrusion 7a by elastic deformation. without even are those capable of deforming the theta _1, workability, thereby improving the design. In addition, the shape is a wedge shape, a circular shape,
Arbitrary, such as a triangular shape.

The backing material C shown in FIG. 13 is a rectangular long plate material, which may be made of a sheathing board, a sheathing insulation board, a gypsum board, an ALC board, a concrete board, a PC board, a rock wool board. Plywood, styrene board, etc., or a synthetic resin foam such as urethane foam, isocyanurate foam, phenol foam, PVC foam, or a composite board made of these. The backing material C has a function of a heat insulating material, a raising material, a soundproofing material, a soundproofing material, a fireproof material, a humidity control material, and the like.
