[Problem that the invention attempts to solve]

However, in the conventional roof plate joining structure configured as described above, each roof plate is connected to the adjacent end surface of the roof plates 1, 1 on the joint waste plate 15 of each stage, as shown in FIG. Between the end faces of the face plate parts 2, 2, there is inevitably and unavoidably a gap A due to their adjacency.
Moreover, since the joint cover plate 18 is fitted with this gap A still existing, the edge bending insertion part of the next stage into the holding engagement part 11 of the previous stage is Although the insertion engagement of No. 8 is intended to prevent rainwater from entering, before it reaches this insertion engagement part, as shown by the arrow in Fig. 5(a), the ingress route through the gap A. This created a problem in that it was impossible to prevent rainwater from entering through the same route.

Therefore, it is conceivable to interpose a waterproof packing between the joint waste plate and the ridge side engaging part of the roof plate, but for example, the flat lower surface of the eave side end shown in Japanese Utility Model Application Publication No. 60-35822 An elastic waterproof gasket with a rectangular cross section is fixed to the gasket, and a joint waste plate with a locking piece provided on the upper surface is placed on the ridge side of the gasket, as shown in Figures 4 and 5.
When using the conventional examples shown in Figures (a) and (b) by replacing only the joint scrap plate, the following problems arise.

That is, since the locking piece is locked to the ridge-side engaging portion of the roof board, the eave-side end of the throw-away board and the eave of the patch may be damaged due to manufacturing errors in the scrap board, locking piece, or roofing material. If there are variations in the position in the ridge direction and the waste board protrudes too far to the eave side, the packing will be pressed against the hanging part of the eave side engagement part provided on the next level (ridge side) roof plate, and the next level (ridge side) A function that allows rainwater that enters the indoor side from the opposite end of the roof board on the ridge side) to collect on the waste board, collect on the front roof board (on the eave side), and drain the rainwater onto the roof board on the front stage (on the eave side). In addition, if the waste board was placed too far on the ridge side, the seal could not be reliably pressed onto the protruding piece of the roofing material, causing water to leak into the room.

This idea solves the above-mentioned problems, and by accurately positioning the joint waste plate and the gasket at the appropriate positions, it is possible to reliably prevent water from leaking into the interior of the room, and it also maintains the gasket for a long period of time. The object of the present invention is to provide a roof plate joint structure for a horizontal roof that can maintain a stable water leak prevention function.
