Description

[Detailed Description of the Invention] The present invention relates to a folded plate structure for a descending ridge in which folded roof plates are roofed along the descending ridge.

In the conventional example, as shown in FIGS. 1 to 3, the roof plate insertion groove 3 was opened obliquely upward, so rainwater entered the roof plate insertion groove 3 and the - roof plate insertion groove 3 Rainwater will begin to flow down the bottom.

Since this rainwater enters the inside of the roof from the connecting portions of the waste boards 2, there is a drawback in that the roof board insertion grooves 3 must be filled with caulking material to prevent rainwater from entering.

The present invention was made in view of the drawbacks of the conventional example,
An object of the present invention is to provide a folding structure for a descending ridge in which rainwater does not infiltrate into the roof plate insertion groove by orienting the opening direction of the roof plate insertion groove diagonally downward.

The present invention will be explained in detail below.

The folded plate structure of the descending ridge according to the present invention is such that a waste board 2 consisting of a right half 6 and a left half 7 is arranged astride the ridgeline 13 of the descending ridge 1.
The end of the right half 6 on the ridge line 13 side is bent into an F-shape to form the ridge line 1.
3 and extends to the left side beyond the ridge line 13, and bends the end of the left half part 7 on the side of the ridge line 13 into an F-shape, and extends to the right side beyond the ridge line 13 on the right half part 6, and the extending end thereof. The left side of the right half 6 is then folded back in an F-shape across the ridgeline 13, and the folded left side end is continuous with the left side end of the right half 6 that crosses the ridgeline 13 to form the right half 6.
A roof plate insertion groove 3 that opens downward at the top and has an F-shape across the ridge line 13 is extended parallel to the ridge line 13 of the ridge 1 over the entire length of the roof plate 2, and the right end of the left roof plate 4 is inserted. The F-shaped bent portion 14a is provided by bending the F-shaped bent portion 14a on the right side, and the tip of the F-shaped bent portion 14a is bent to the right side.
The folded piece part 14 is formed by continuously extending it in an F-shape along the back surface of the roof panel a, and the left end of the right roof board 4 is bent to the left in a F-shape to form a F-shape folded piece part 12. Form the left and right roof panels 4 on top of the scrap board 2, and then fold the right roof panel, the F-shaped bent piece 1 of 4.
2 is fitted into the roof plate insertion groove 3, and the folded piece 14 provided at the extreme end of the left roof plate 4 is fitted into the roof plate insertion groove 3, and configured as described above. This solves the drawbacks of the conventional example.

Next, the present invention will be described in detail according to illustrated embodiments.

As shown in FIG. 4, the waste board 2 is bent into a substantially V-shape along a central folding line 5, forming a right half 6 and a left half 7, respectively.

The left half 7 and the right half 6 are folded back over substantially the entire length to form a gap 8.

The left half portion 7 is folded to the right in the vicinity of the folding line 5 and then folded back to the left again to provide a roof plate insertion groove 3 and a double folded piece portion 9. The opening edge 10 is bent obliquely downward along the right half 6.

Therefore, the roof plate insertion groove 3 has a substantially V-shape, and its opening direction is directed diagonally downward.

The left roof board 4 and the right roof board 4, which are respectively laid on the left and right sides of the descending ridge 1 on the waste board 2, have the following shapes.

That is, the right end of the left roof plate 4 is bent to the right in a V-shape to form a V-shape bent portion 14a, and the V-shape bent portion 1 is provided.
The folded piece part 14 is formed by extending the tip end of the bent part 4a in an F-shape along the back surface of the bent part 14a.

Further, the left end of the right roof plate 4 is bent leftward in a C-shape to form a C-shape bent piece.

Then, the waste board 2 is placed over the ridgeline 13 on the roof's descending ridge 1, and the left and right halves 7 and 6 are sealed onto the roof base board 11. Lay the roof shingle 4 at The folded piece 14 is inserted into the roof plate insertion groove 3.

Since the present invention is constructed as described above, the left and right roof panels are fitted into the corner-shaped folded and folded pieces into the corner-shaped roof panel insertion grooves. This makes it difficult to pull out and makes the joint strong.The bent and folded pieces of the left and right roof panels fit into the F-shaped roof board insertion groove on the left and right sides. It only needs to be installed in one place, and since the opening of the roof board insertion groove faces diagonally downward and crosses over the ridgeline in an F-shape, rainwater flowing down on the roof board will not enter the roof board insertion groove. , it has the advantage of being able to exhibit excellent waterproofing effects without being filled with caulking material.
