Description

DETAILED DESCRIPTION OF THE INVENTION In the present invention, the lower end of the metal plate 1 is folded back to the back side in a substantially U-shape to form the locking bent piece 2, and the upper end of the metal plate 1 is folded back to the front side in a substantially U-shape. Hook bent piece 3 to which the locking bent piece 2 is locked
, the end of the bent hook piece 3 is folded back toward the ridge side, and the tip of the folded portion protrudes further toward the ridge side than the bent hook piece 3 to form a fixed piece 4 parallel to the metal plate 1. The flat upper surface 7 of the material 5 is made convex upward than the flat lower surface 6, and a groove with a depth equal to the wall thickness of the fixing piece 4 is formed at the upper corner of the step formed by the lower surface 6 and the upper surface 7. The middle surface 10 is shaped, and the lower surface 6 of the waterproof material 5 is attached to the back surface of the metal plate 1, and the lower surface 6 of the waterproof material 5 is attached to the back surface of the portion disposed within the locking bent piece 2 at the lower end of the waterproof material 5. A gap 11 into which the hanging bending piece 3 is fitted is formed between the lower horizontal piece 2a of the retaining bending piece 2, and the upper part of the waterproofing material 5 is made to protrude toward the ridge side than the metal plate 1, and the middle surface 10 This roofing material is characterized in that a fixing piece 4 is provided and the fixing piece 4 and the upper surface 7 of the waterproof material 5 are substantially flush with each other.

An object of the present invention is to provide a roofing material that prevents backflowing rainwater from accumulating on the fixed pieces, has a large waterproofing effect, and can prevent the fixed metal plates from being deformed.

The present invention will be explained in detail below with reference to Examples.

The lower end of the metal plate 1 is folded back in a substantially U-shape to form a locking bent piece 2, and the upper end of the metal plate 1 is folded back in a substantially C-shape to the front side to be locked by the locking bent piece 2. The hook bending piece 3 is formed into a fixing piece 4 by folding the end of the hook bending piece 3 toward the ridge side and making the tip of the folded portion protrude further toward the ridge side than the hook bending piece 3.

Here, the metal plate 1 and the fixed piece 4 are parallel to each other.

The waterproof material 5 is made of a waterproof material such as asphalt board, rubber sheet, waterproof paper, waterproof cloth, or resin board, and the upper surface 7 of the waterproof material 5 is more convex than the lower surface 6. Further, a middle step surface 10 having a depth equal to the wall thickness of the fixing piece 4 is provided at the upper corner of the stepped portion formed by both.

Thus, the lower surface 6 of the waterproof material 5 is layered on the back surface of the metal plate 1 and is intermittently bonded with adhesive or adhesive 8.

In this case, the middle surface 10 is superimposed on the back surface of the fixed piece 4.

-i. The upper surface 7 of the waterproofing material 5 protrudes from the metal plate 1 toward the ridge side, and at this time, the back surface of the portion of the waterproofing material 5 disposed inside the retaining bent piece 2 and the retaining bent piece 2 A gap 11 into which the hook bending piece 3 is fitted between the lower horizontal piece 2a and the lower horizontal piece 2a.
The fixed piece 4 is disposed and bonded to the middle surface 10, and the upper surface 7 of the waterproof material 5 and the fixed piece 4 are on the same surface.

The roof material A having the above structure is laid on the roof base material B, the fixed piece 4 is nailed, the fixed piece 4 and the waterproof material 5 are nailed to the roof base material B, and then the bent piece 3 is hooked. The fixing bending piece 2 of the upper roofing material A is hooked onto the roofing member A, and nails are driven from the fixing piece 4 of the upper roofing material A, and construction is continued in the same manner one after another.

In this case, in the shingle part at the rear end of the roof, the side edge of the waterproof material 5 that is partially adhered is peeled off and cut off as shown by arrow A in FIG. 3, and the side edge of the metal plate 1 is removed. It is folded as shown by the arrow in Figure 3.

At the eaves of a single roof, the lower end of the waterproof material 5 is peeled off and bent as shown by arrow 8 in Figure 4 to drain water.

Number 9 in the figure is a wooden board from the eaves.

In the present invention, as described above, the lower end of the metal plate is folded back in a substantially U-shape to form a locking bent piece, and the upper end of the metal plate is folded back in a substantially C-shape to the front side to form a locking bent piece. Since the hooked bent piece is shaped so that the pieces are locked, when connecting the roofing materials, the connecting piece can be reliably connected by locking the hooked bent piece to the hooked bent piece. Moreover, since the lower surface of the waterproofing material is attached to the back of the metal plate, it is possible to prevent easily dented metal plates such as aluminum and copper from being dented by the waterproofing material, and the double structure of the metal plate and waterproofing material provides waterproofing. This has the advantage that the end of the hook bending piece is folded back toward the ridge side, and the tip of the folded part protrudes further toward the ridge side than the hook bending piece, making it a fixed piece parallel to the metal plate, which reduces the flatness of the plate-shaped waterproof material. The upper surface, which is flatter than the lower surface, is convex upward, and a middle step surface with a depth equal to the wall thickness of the fixing piece is formed at the upper corner of the step formed by the lower surface and the upper surface, and the waterproofing is made. The lower surface of the material is attached to the back surface of the metal plate, and the bent piece is hooked between the back side of the portion of the lower end of the waterproof material disposed within the locking bent piece and the lower horizontal piece of the locking bent piece. The upper part of the waterproofing material is made to protrude toward the ridge side than the metal plate, and a fixing piece is provided on the middle surface, and the fixing piece and the upper surface of the waterproofing material are almost flush with each other. Therefore, when connecting the roofing materials, the lower back side of the waterproofing material of the upper roofing material should be flush with the upper surface of the fixing piece and the waterproofing material, which are almost flush against the lower roofing material, without any gaps. In this way, the waterproofing materials, including the fixing pieces, can be brought into close contact with each other facing upwards from the joints of the roofing materials, so water can be prevented from blowing up from the joints and rising upward. In addition, even if rainwater rises to the ground, it can flow down the fixed piece that is flush with the waterproofing material and drain away, and because the fixed piece and the waterproofing material are flush with each other and are not stepped, water will accumulate. The advantage is that there is no problem.
