Description

[Detailed Description of the Invention] The present invention relates to the shape of a drain plate used for the eaves of a roof.

As shown in the cross-sectional view seen from the direction of the rafters in Figure 1, the conventional eaves drainage board (A) is a rectangular board that is bent into a cross-sectional shape to the hanging end and the horizontal piece, and the outside of the horizontal piece (C) is bent. It was constructed by folding the end slightly diagonally upward to create a draining section.

This eaves drainage board A is fixed onto the roof board that forms the roof surface, and flat tiles, for example, are placed and fixed onto the eaves drainage board A, allowing rainwater to flow between the tiles and the field board. This is to prevent the rise in

However, due to the protrusion of the draining board, a gap was created between the back side of the tile and the horizontal piece of the eaves draining board, resulting in a poor rain control effect and a reduction in the aesthetic effect.

The present invention was developed in view of the above facts, and the object is to provide an eaves drainage board that improves the rain protection effect and enhances the aesthetic effect.

An embodiment of the eaves drain plate A of the present invention will be explained with reference to FIG. 2.

A is the eaves drainage board.

The eaves drainage board A consists of a hanging piece 2, a horizontal piece 3, a folded horizontal piece 4, and a free end 5.

More specifically, the longitudinal side end portions of the long plate 1 are bent to form a hanging piece 2 and a horizontal piece 3, and the horizontal piece 3 is folded back downward to extend the free end 5 from the hanging piece 2. Further, the free end 5 of the folded horizontal piece 4 is bent upward into a triangular shape.

Furthermore, a plurality of nail holes 7 are bored in the longitudinal side surface of the hanging piece 2.

Further, a plurality of nail holes 6 are also bored on the longitudinal side of the horizontal piece 3.

This will be explained with reference to FIG. 3, which shows the state of use of the above-mentioned eaves drainage board A.

An eaves drainage board A is placed on the roof board 11, and the hanging piece 2 is fixed with nails 13 through nail holes 7 provided in the hanging piece 2.

The horizontal piece 3 is fixed with a nail 12 through a nail hole 6 provided in the horizontal piece 3.

Furthermore, a roof tile 10, such as a flat roof tile, is placed and fixed on the eaves drainage board A.

As in the above configuration, the free end 5 of the folded horizontal piece 4 of the eaves drainage board A is bent upward, so when the tile 10 is placed on the horizontal piece 3, the tile 10 will be leveled by its own weight. The back surface of the piece 3 contacts the triangular free end 5 of the folded horizontal piece 4, so that the contact area of the horizontal piece 3 can be increased.

Therefore, a gap is less likely to be formed between the back surface of the tile 10 and the horizontal piece 3, so that there is little rain infiltration from the eaves toward the ridge, and an aesthetic effect can also be achieved.

As described above, the present invention bends the longitudinal side ends of a long plate to form a hanging piece and a horizontal piece, and folds the horizontal piece downward to form a folded horizontal piece having a free end from the hanging piece. In addition, since the free end of the folded horizontal piece is bent upward, it is possible to produce a good aesthetic effect as a rain cover.
