Regarding this, it is easy to construct, can be used for any connection part, and is designed to reliably prevent rainwater from entering through the connection part.

<Prior Art> As is well known, waste boards are attached to the joints of horizontal roofing materials forming the roof surface of buildings to prevent rainwater from entering.

An example of a conventional waste board for connecting horizontal roofing materials is the one described in Publication of Utility Model Publication No. 57-36741. A support section having horizontally opening receiving grooves formed on the left and right sides is provided in the length direction approximately in the center of the width direction, and a shallow groove-shaped guide section parallel to the support section and allowing rainwater to flow down in an inclined direction is provided on the support section. A plurality of roof members are formed on the left and right sides of the roof member, and a bent piece that fits into the engaging portion of the roofing material is formed at the front end.

<Problems to be Solved by the Invention> However, since the above-mentioned conventional scrap boards are attached by sliding them laterally on the edge of the roofing material, the connection part does not have enough room to slide the roofing board laterally. cannot be used for In addition, because the fit between the bent piece of the waste board and the engagement part formed on the roofing material is shallow, it is easy to come off, and the roofing material may be rolled up by strong winds, and the tip of the bent piece may be attached to the rear end of the roofing material. If it comes off the engagement part and is located at the rear, rainwater may penetrate through the bent piece and seep into the attic.

<Means for Solving the Problems> The present invention has been proposed in view of the above, and has a locking portion at the front end, an engaging portion at the rear end, and a protrusion or stepped portion is formed on the locking portion. The roofing materials that have been used are horizontally roofed, and the adjacent roofing materials on the left and right are connected with scrap boards, and the locking portions of the upper roofing materials are locked to the engaging portions of the lower roofing materials. In such a roof, the downwardly bent piece formed at the front end of the scrap board and fitted into the locking part of the roofing material is arranged so that the front end is higher than the lowest height part in the locking part and is located inside the locking part. It is characterized by being composed of one half portion whose height is approximately equal to the height of the locking portion, and the other half portion whose height is lower than the lowest height portion within the locking portion.

<Function> The bent piece provided at the front end of the waste board is divided into one half which is higher than the height of the lowest height part in the locking part of the roofing material and the other half which is lower than the height of the said lowest height part. With this structure, one half of the bent piece of the waste board can be firmly fitted to the locking part of one of the left and right roofing materials, and the other roofing material can be attached from the front of the waste board. The other short half of the folding piece can then be engaged in the locking part of the roofing material.

For example, it can be used for rising parts, descending ridges, valleys, etc. of roofs.

FIGS. 4 and 5 show another embodiment of the present invention, and this embodiment differs from the embodiment described above in the following points:
The structure of the locking part 5 provided at the front end of the roof material 1 and the engagement part 3 provided at the rear end are different.

That is, the locking part 5 has a bent piece 5a that is bent downward in a U-shape at the front end of the roofing material 1, and the bent piece 5a is bent downward in a U-shape.
The distal end portion of the horizontal surface portion 5d extending rearward from the lower edge of the folded portion 5e is bent upward, and the upper end portion of the folded portion 5e is bent horizontally toward the engaging portion 3 to form the lower surface portion 5f.
has been formed.

On the other hand, the engaging portion 3 provided at the rear end of the roof material 1 is provided via a step portion 17. That is, the stepped portion 17 provided at the rear edge of the roof material 1 is formed by bending the upper part of the first upright surface 17a that is bent upward almost horizontally toward the rear, so that the stepped portion 17 is almost the same as the horizontal surface portion 5d of the locking portion 5. By forming a first upper surface 17b having the same height as the first upper surface 17b, and bending the rear end of the first upper surface 17b upward, a second upper surface 17b having approximately the same height as the folded portion 5e of the locking portion 5 is formed.
A raised surface 17c is formed, and the upper part of the second raised surface 17c is bent rearward substantially horizontally to form a second upper surface 17d that is longer than the lower surface 5f of the locking portion 5.

The engaging part 3 formed on the second upper surface 17d of the step part 17 is formed by folding the tip of the second upper surface 17d upward into a hairpin shape to form a clamping part 3d, and the tip of the clamping part 3d has a mountain shape. A receiving portion 3e is formed.

Therefore, according to the embodiment described above, not only can roofing be done without moving the roofing material 1 in the lateral direction, but also rainwater can flow from the eaves side during rainstorms on the roof that has been covered as described above. Even if the roofing material 1 rises against the slope toward the top of the roofing material 1, the first upright surface 17a of the stepped portion 17 of each roofing material functions as a water return and prevents rainwater from rising. Therefore, it is possible to prevent a large amount of rainwater from spraying or accumulating at the connecting part between the locking part 5 and the engaging part 3, and it is possible to prevent rainwater from flowing from the connecting part of the vertically adjacent roofing materials 1, 1. can effectively prevent the infiltration of
Furthermore, even if the connecting part between the locking part 5 and the engaging part 3 gets wet, since the receiving part 3e is formed in the shape of a mountain at the end of the engaging part 3, the intrusion of rainwater due to capillary phenomenon is blocked. There is no risk of water leakage. Note that if the receiving portion 3e formed in the engaging portion 3 is formed into a plurality of mountain shapes, the effect of blocking rainwater will be further enhanced. Further, the step portion 17 provided on the roofing material 1 may be one step or may be multiple steps.
