BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a single character roofing material used for roofing.

[0002]

2. Description of the Related Art A single-roofed roofing material is formed by bending a peripheral edge of a substantially square plate material 50 toward a front side and a back side and engaging pieces 5.
1, 52, 53, and 54, and the engaging pieces are sequentially engaged and connected to form a roof surface. Each of the engaging pieces 51, 52, 53, 54 is formed in a parallel band shape, and the engaging piece 53 bent to the front side when connecting in the lateral direction is the same as the engaging piece 54 bent to the back side. The width b of the upper engaging piece 51 bent toward the front side in the ridge side direction for bending to the widths a and a 'and connecting vertically is the width b of the lower engaging piece 52 bent toward the back side in the eaves side direction. 'It is common to make it wider (Figure 5).

The reasons why the bending widths b and b 'are different between the upper side and the lower side are, in addition to the improvement in waterproofness, avoiding a protrusion D (FIG. 8), which is an obstacle to crossover described below. That's why. Therefore, as shown in FIG. 5, the pre-formed 50a is joined as shown in FIG. 6, and the ridge side is bent to the front side and the eaves side to the back side as shown in FIG. They were roofing together.

[0004]

According to the prior art, the gripping operation not only requires skill and labor, but also requires four materials when the engaging pieces 53 and 54 are folded back to the front side or the back side.
Since the sheets overlap, the material is shifted by the amount of the material or more, and the protruding portion D is formed (FIG. 8). When the protruding portion D is bent to the back side, the width b of the engaging piece 51 bent at the ridge side is changed to the engaging piece 52 bent to the back side.
Is wider than the width b ', the protrusion D becomes obstructive and must be cut off.

[0005]

Means for Solving the Problems An engaging piece provided at a peripheral edge of a substantially square shape is formed into an oblique shape which becomes wider from one side end to the other side end to form a projecting portion D. It is an object of the present invention to provide a roofing material which can be easily joined right and left and up and down without performing, and the position of a roofing plate does not shift at the time of construction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a roofing material A for one character according to an embodiment of the present invention.

A is a roofing material formed by bending an end of a metal roof plate such as a copper plate. The roofing material A has engaging pieces 11, 12, 13, and 14 bent around a substantially square plate material, and the upper engaging piece 13 having one side edge turned to the surface side and the other upper side engaging piece 13 are folded. A lower engagement piece 14 having an edge turned back to the back side is provided, and a lower engagement piece 12 having the eaves edge turned back to the back side and an upper engagement piece 11 having the ridge end turned back to the front side. Is provided. The upper engagement piece 11 having the edge on the ridge side folded back toward the front side is wider than the lower engagement piece 12 and is formed by bending.

[0008] Each of these engagement pieces 11, 12, 13,
In order to facilitate watertightness and engagement, a small gap g is formed at the four corners at the time of folding, and one side end has a narrow width of x1 and x12, and the other side end has a width of x1 and x12. Wide x
2. Fold it back at the width of x22, and engage the engaging pieces 11, 12, 13,
14 are obliquely shaped, the engaging pieces 11 and 12 and the engaging pieces 13 and 14 are parallel to each other, and each edge 1
The intersections of 1a, 12a, 13a and 14a are substantially perpendicular to each other. Although not shown, the engagement pieces 13, 14
Instead of folding in an oblique shape, the left and right ends are cut slightly obliquely in the state of a plate, and when the engagement pieces 13 and 14 are formed, one side end x12 and the other side end x22 are folded back with the same width. You may.

[0009]

[Effects] The roofing material A formed as described above is joined to each other by engaging the engaging pieces 11, 12, 13, 14 and the other members, and is connected to each other. The upper engagement piece 13 and the lower engagement piece 14 of the roofing material A are engaged and joined (FIG. 2). At this time, since the upper engagement piece is formed in an oblique shape, the upper engagement piece 1 of one roofing material A is formed.
The upper portion X of the other roofing material A is engaged with the narrower portion X1 of the other roofing material A so as to fit into the wider portion X1 of the other roofing material.

In the roofing material A for one-letter roofing which is connected and constructed as described above, the engaging pieces 11, 12, 13, and 14 each have an oblique shape (the edges 11a, 12a, 13a, and 14a intersect each other at a substantially right angle). ), The edge 11a of the upper engagement piece 11 becomes parallel to the eaves, and the edge 11a when sequentially connected is substantially straight (FIG. 3).

After the rows are mounted on the first row (eaves) in a row, the roofs are sequentially laid in the direction of the ridge in two steps, three steps, and so on. At this time, the lower engaging piece 12 of the next stage roofing material A is engaged with the straight edge portion 11a of the engaging portion 11 and the roofing material A is roofed, so that the roofing material A is attached in parallel along the eaves of the roof. It is not necessary to construct the roofing material by hand processing (grabbing the engaging portion by bending or cutting off the protruding portion D) as in the prior art, and it is sufficient to simply hook the engaging portion sequentially, It is extremely effective because it has various effects, such as the appearance after construction is gracefully roofed.
