Any structure may be used as long as it also prevents rainwater from seeping in.

A fitting portion 4 is formed on one side edge of the roof plate 1 described above, and a fitting portion 5 is formed on the other side edge.

The above-mentioned fitting part 4 is inserted into and fitted into the fitting part 5 of the horizontally adjacent roof board 1, and the side edge of the roof board 1 is slightly stepped downward and bent to extend outward. It is configured as an extended flat plate-like extension piece 6. The fitting portion 5 on the other side edge includes a bent portion 7 folded downward from the side edge of the roof sheet 1, and a flat plate-shaped extension piece extending from the tip of the bent portion 7 to the outside of the side edge of the roof sheet. It consists of 8. The above-mentioned fitting part 4 and fitting part 5 are not the entire depth and width of the roof board 1,
The width is approximately the same as the depth excluding the engaging portion 2 and the locking portion 3. Then, the upper and lower edges of the side edges of the roof sheet 1 where the fitting portions 4 and 5 are not formed are cut and removed during manufacturing, or are bent and overlapped on the inner surface of the side edges of the roof sheet 1. do it.

When roofing the roof sheets 1 described above, the fitting portions 4 are fitted into the fitting portions 5 of the left and right adjacent roof sheets 1 to form the connecting portions 9. A waste plate 10 is fitted onto the lower surface of the connecting portion 9 in advance. This waste board 10 is along the length direction of the connection part 9, and has a downward fitting piece on the lower edge that is inserted into the side edge of the engagement part 2 of the left and right roof panels 1 located on the lower edge side of the connection part 9. 11, and the upper edge has a covering piece 1 that covers the side edge of the locking part 3 of the left and right roof panels 1 located on the upper edge side of the connecting part 9 from above.
form 2.

In addition, on the left and right side edges of the waste board 10, water return pieces 13, 13 are formed that are bent upward in a folded manner, and a receiving part 14 and a protruding part 15 are formed in the middle in the width direction in the length direction. Form to extend. In the embodiment shown in the drawings, the receiving portion 14 is located approximately at the center of the waste board 10, and is bent toward one side so as to stand up in a hook shape. Further, two protrusions 15 are formed, one of which has a hook shape that stands up facing the receiving section 14, and the other one has a hook shape that stands up in the same direction as the receiving section 14. The receiving portion 14 and each protruding portion 15 are arranged at approximately the same interval. Note that the lower and upper edge portions of the receiving portion 14 and the protruding portion 15 extending to the fitting piece 11 and the covering piece 12 are preferably flattened.
