The roof material Y of this embodiment has a lower overlapped portion Y1 at one end and an upper overlapped portion Y2 at the other end. In this embodiment, one end of the substantially rectangular material in plan view is the lower overlapped portion Y1, and the other end opposite to the one end is the upper overlapped portion Y2. In this embodiment, a reinforcing fitting portion Y3 and a groove plate portion Y4 are formed between the lower overlapping portion Y1 and the upper overlapping portion Y2. Although the reinforcing fitting portion Y3 is formed in this embodiment, it is not essential, and only the groove plate portion Y4 without the reinforcing fitting portion Y3 may be used. However, by forming the reinforcing fitting portion Y3, the strength of the roof material itself is improved, and the risk of deformation of the roof material Y or occurrence of a fall accident due to stepping out is reduced.

The lower overlapping portion Y1 of this embodiment has a fastening bottom surface Y11, and a first engaging portion Y12 and a second engaging portion Y13 erected from both ends of the fastening bottom surface Y11. When viewed from the end face, a first engaging portion Y12 and a second engaging portion Y13 are erected on both sides of the fastening bottom surface Y11.

The fastening bottom surface Y11 of this embodiment is used to fix the roof material Y to the base by driving the fastening tool B from above. The width of the fastening bottom surface Y11 of this embodiment is formed wider than the head width of the fastening tool B. As shown in FIG. In the roof material Y of this embodiment, the height of the grooved plate portion Y4 and the fixing bottom surface Y11 are substantially the same when attached. Therefore, the grooved plate portion Y4 is placed on the base in a stable state, and the fixing bottom surface Y11 can be firmly fixed by the fixing tool B. As shown in FIG. Therefore, the height dimension from the fixing bottom surface Y11 and the grooved plate portion Y4 to the upper end of the first engaging portion Y12 and the upper end of the second engaging portion Y13 can be sufficiently secured, and the first engaging portion Y12 and the second The engagement portion Y13 can be provided with elasticity.

The first engaging portion Y12 and the second engaging portion Y13 of this embodiment have elasticity. For example, when a force directed toward the fastening bottom surface Y11 acts on the first engaging portion Y12 and the second engaging portion Y13, there is a stress that restores. Therefore, when the adjacent roof materials Y and Y are fitted to each other, the structure is such that when they are fitted, they are easily fitted, and after they are fitted, they are difficult to come off.

The first engaging portion Y12 of this embodiment has a first side wall Y121 erected from one end of the fastening bottom surface Y11, and a first fitted portion Y122 bent outward from the upper end of the first side wall Y121. are doing. The first engagement portion Y12 of this embodiment is formed closer to the end portion of the roof material Y than the fastening bottom surface Y11. In this embodiment, the first engaging portion Y12 has a substantially mountain-like cross section with the upper end of the first side wall Y121 as the top. The upper overlapped portion Y2 of the roof material Y' is fitted by being pushed along the upper inclined surface Y122a of the first fitted portion Y122 of the roof material Y to the first fitted end portion Y122b. there is

The second engaging portion Y13 of this embodiment is formed between a second side wall Y131 erected from the other end of the fixing bottom surface Y11 and the second side wall Y131 folded outward from the upper end of the second side wall Y131. It has a second fitted portion Y132 which has a substantially V-shaped cross section and is hollow. The second engaging portion Y13 of this embodiment is formed closer to the groove plate portion Y4 of the roof material Y than the fastening bottom surface Y11. In this embodiment, the second engaging portion Y13 is formed by folding down with the upper end of the second side wall Y131 as the apex and further folding toward the second side wall Y131. The overlapping portion Y2 of the roof material Y' is fitted by being pushed along the upper inclined surface Y132a of the second fitted portion Y132 of the roof material Y to below the side curved top Y132b.

In the present embodiment, the space formed between the second side wall Y131 and the second fitted portion Y131 is hollow and is not filled with a hard foamed synthetic resin heat insulating material or the like. Being hollow in this manner increases the elasticity of the second engaging portion Y13. Due to the high elasticity, the adjacent roof materials Y and Y' are easily fitted to each other and are difficult to come off.

In this embodiment, the lower portion of the second engaging portion Y13 between the fastening bottom surface Y11 and the groove plate portion Y4 is open. Therefore, the roof materials Y and Y'' of this embodiment can be superimposed on each other. At this time, the second engaging portion Y13 can be inserted into the lower opening of the second engaging portion Y13 of the upper roof material Y''. As a result, it is possible to overlap and attach the roof materials Y and Y'' adjacent to each other in the running direction of the roof by providing a predetermined overlap margin.

In this embodiment, the first side wall Y121, the fastening bottom surface Y11, and the second side wall Y131 are formed to have an inverted U-shape in cross section, and the first side wall Y121 and the second side wall Y131 are folded downward toward the outside. there is Therefore, an opening is provided between the upper end of the first side wall Y121 and the upper end of the second side wall Y131, that is, the upper side of the fastening bottom surface Y11. With such a shape, the fixing tool B such as a screw can be passed between the first side wall Y121 and the second side wall Y131 and can be inserted into the fixing bottom surface Y11.

In this embodiment, a concave portion Y132a1 is formed on the upper slope Y132a of the second fitted portion Y132. By forming the recess Y132a1, it is possible to prevent rainwater from entering between the lower overlapped portion Y1 and the upper overlapped portion Y2 due to capillary action. Furthermore, even if water enters between the lower overlapped portion Y1 and the upper overlapped portion Y2, the first side wall Y121, the fastening bottom surface Y11, and the second side wall Y131 can be drained at the inverted U-shaped cross section. At this time, it is desirable that waterproofing such as packing is applied to the portion where the fastening device B is inserted.

The upper overlapping portion Y2 of this embodiment has a first fitting portion Y21 and a second fitting portion Y22. In the superimposed portion Y2 of this embodiment, both sides of the top plate portion Y23 are bent obliquely downward and further bent inward to form a first fitting portion Y21 and a second fitting portion Y22. That is, the first fitting portion Y21 and the second fitting portion Y22 of the present embodiment are formed by bending the center of the top plate portion Y23 so as to have a substantially V-shaped cross section that protrudes inward from each other. In this embodiment, the groove plate portion Y4 side is the first fitting portion Y21, and the end portion side is the second fitting portion Y22. The first fitting portion Y21 of the other roof material Y' is fitted to the second fitted portion Y132 of the one roof material Y, and the second fitting portion Y22 of the other roof material Y' is fitted. In this embodiment, the first fitting portion Y21 and the second fitting portion Y22 of the upper overlapping portion Y2 are also formed by bending a thin metal plate, and therefore have elasticity.

The one first fitted portion Y122 and the other first fitting portion Y21 are fitted together by the elasticity of both, and the one second fitted portion Y132 and the other second fitting portion Y22 are fitted together. Fitted and mounted by means of elasticity.

In this embodiment, the first fitting portion Y21 and the second fitting portion Y22 of the roof material Y' are in contact with the upper ends of the first side wall Y121 and the second side wall Y131 of the adjacent roof material Y. The superimposed portion Y2 of Y' is lightly stepped on and pushed from above. Then, the gap between the first fitting portion Y21 and the second fitting portion Y22 of the roof material Y' is widened by elasticity, and the first fitted end portion Y122b of the first fitted portion Y122 of the roof material Y and the It is designed to be fitted to the side curved top portion Y132b of the second fitted portion Y132. On the other hand, the first fitted portion Y122 and the second fitted portion Y132 of the roof material Y are lightly stepped on the overlapping portion Y2 of the adjacent roof material Y', and the first fitted portion Y21 and the second fitted portion Y132 are lightly stepped on. When the portion Y22 is pushed from above, the opening between the upper ends of the first fitted portion Y122 and the second fitted portion Y132 of the roof material Y is elastically applied with force in the inward direction and narrowed. The portion Y21 and the second fitting portion Y22 are designed to be easily fitted.

The easy-to-fit structure like this embodiment is most suitable for attaching the roof material Y to the steel frame base S. For example, when the interval between the steel frame foundations S and S is wide, it is difficult to fit the roof materials Y and Y in the vicinity of the middle of the interval unless a strong force is applied, or the force applied is too strong. and the roof material Y is deformed. In the worst case, it may lead to a fall accident of the builder. In this embodiment, the construction workability and safety are high because the roof materials Y and Y can be easily fitted to each other only by lightly stepping on the upper overlapping portion Y2 from above.

In this embodiment, the steel frame base S is hat-shaped steel. For example, the steel frame foundation S includes a hat-shaped steel used as a horizontal purlin for repairing an aged corrugated slate roof. In addition, the steel frame base S may be of any cross-sectional shape, such as C-shaped steel or angle-shaped steel. In addition, the present application is not limited to a steel frame foundation, and the foundation may be a non-steel frame, such as a fireproof board or roofing board.

In this embodiment, a reinforcing fitting portion Y3 is formed between the lower overlapping portion Y1 and the upper overlapping portion Y2. This reinforcing fitting portion Y3 may be fitted in the reinforcing fitting portion by fixing the reinforcing mounting member T to the base. With such a structure, the mounting strength of the roof material Y can be further improved. The structure using the reinforcing fitting portion Y3 and the reinforcing mounting member T may be used for the entire roof, or may be used locally only for portions of the roof that require high strength.

In this embodiment, the roof materials Y and Y'' adjacent to each other in the direction of flow of the roof are overlapped, and the reinforcing fitting portion Y3 is fitted. With such a structure, the attachment strength of the connecting portion is improved. In addition, since the overlapping roof materials Y and Y'' do not easily bend, it is difficult for the roof to open, and it is possible to prevent flooding.
