However, the above (1) to (4) are performed while hooking the corner ridge plate arranged in a substantially right angle to the roof material at both ends. A great skill is required in order to construct the board in a satisfactory manner, and there is a risk that water leaks due to variations in the construction, shifts in the flow direction due to external pressure such as snow, and in the worst case, falls. Furthermore, it is necessary to prepare separate corner ridge boards according to the change in roof slope,
When one type of corner ridge plate is used forcibly, stress concentrates at the lower center of the roof due to the slope of the roof. There was a danger that this would lead to an increase or cost increase, or confusion at the time of construction.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view of a roofing material according to the present invention. FIG. 1 is an explanatory view showing the roofing material. FIG. 1A is a perspective view showing a front surface portion, and FIG. 1B is a perspective view showing a rear surface portion. That is, the roofing material A is a metal plate (a color steel plate, an aluminum plate, a titanium plate, a stainless steel plate, a sandwich steel plate, a clad steel plate, or the like) or a synthetic resin plate formed by roll forming, press forming, or the like. As shown in FIG. 9, in the lower corner building of the roof, a plurality of roofs are laid for each step to function as a waterproofing material, a covering material, and a decorative material.

[0006] More specifically, the roofing material A is formed into a fan shape with a substantially semi-conical shape as a whole, and as shown in FIG. 2 which is an end view of a portion indicated by the II line in FIG. The cross section is formed in a mountain shape from the vertex 1 corresponding to the central portion of the decorative surface B. Further, as shown in FIG. 3 which is an end view of a portion indicated by a roll line in FIG. 1 (b), a locking tongue C formed on the decorative surface B side is bent in a substantially U-shape at the upper part. Formed at the bottom, a stepped decorative surface D bent to the back surface 2 side
And a folded piece formed by forming a buffer projection E projecting outward or inward at the center 3 of the step decorative surface D, and bending the tip 4 of the step decorative surface D substantially in parallel with the decorative surface B. F, a notch portion 5 in which a central portion of the folded piece F is partially removed, an engaging tongue piece G protruding right and left across a predetermined width across the notched portion 5, and both sides of the folded piece F Part 6
Also, a locking piece 7 protruding over a predetermined width is formed. Further, a bent tongue-shaped fitting tongue H is formed on the left and right side edges 8 of the decorative surface B.

The vertical section of the decorative surface B is substantially the same as the small shape of the decorative surface 9 of the step-like roofing material I as shown in FIG. 7, for example, and the step decorative surface D also corresponds to the step 10 of the roofing material I. This creates a moderate step and improves the design.

The engaging tongue C engages with the engaging tongue G to connect the turning material A up and down, thereby preventing the turning material A from flapping, and the folded piece F of the upper turning material A.
Are in close contact with the upper part of the decorative surface 9 of the lower roofing material A to improve waterproofness.

As shown in FIGS. 4 (a) and 4 (b) or FIGS. 5 (a) to 5 (c) and FIGS. 6 (a) to 6 (d), the cushioning projection E is provided at the center 3 of the stepped decorative surface D. It is a shape that protrudes or protrudes in a conical shape from the surface B toward the tip 4, and even if the two decorative surfaces B are changed with the vertex 1 as a bending line in accordance with the change in the roof gradient, the figure is elastically deformed. As shown by the two-dot chain line in FIG. 6 (a), the height h of the buffer protrusion E is raised, and the center 3 of the step decorative surface D is not cracked, and the waterproofness and the design are improved. It is.

In particular, FIG. 4B is a side view of the haher portion of FIG. 4A showing a side view of the roofing material A. As shown in FIG. This is the buffering projection E when it projects to FIG. 5 (a) shows a case in which the engaging tongue piece G is not formed near the notch portion 5 of the folded piece F,
(B) is the bent roof material A of FIG. 1 in which the notch 5 is not formed and the bent portion 11 is formed. (C) is formed by reducing the width of the engaging tongue piece G in the above (b). 7 shows the vicinity of the buffer protrusion E in the case of performing the above.

Next, FIGS. 6 (a) to 6 (d) show a partially enlarged view of the center 3 of the stepped decorative surface D of FIG. 4 (b). In particular, FIG. 6 (a) is the reverse of FIG. In the case of projecting, (b) shows the buffer projection E projecting in a pentagonal pyramid shape, (c) shows the buffer projection E of (a) formed in a conical shape, and (d) shows the buffer projection E projecting in a conical shape. Things.

Further, Kakarigoshitahen G, as shown in FIG. 5 (b), (c) , is to change also the length l ₃ corresponds to the gradient of the roof. That is, longer large enough length l ₃ greater the angle of slope of the roof, smaller the length l ₃ the smaller the angle of the slope is to shorten. That is, as the gradient angle increases, the angle θ _{1 of the} vertex 1 shown in FIG. 2 also increases. (Note that the roofing material A can easily follow the change in θ ₁ by utilizing the elastic deformation of the material.) Accordingly, the angle θ ₂ of the skirt point 12 in FIG.
Is shifted toward the eaves as a whole. Therefore, the engaging tongue piece G
If the length l ₃ is short, the engaging tongue piece C does not engage with or engage with the engaging tongue piece C, and the risk of fluttering or falling off increases. Therefore, it is intended to advance Kakarigoshitahen leave longer formed length l ₃ of G, to cut in response to the slope of the roof at the factory shipment. In this way, the roofing material A
Since only one type can cope with a change in roof slope, costs such as manufacturing equipment and costs can be reduced.

The fitting tongue H is for connecting the roofing material A and the roofing material I by using a waterproof joint material J as shown in FIG. That is, the fitting tongue 15 of the roofing material I is attached to the left and right connecting tongues 13 and 14 formed in a goby shape on the waterproof joint material J.
And the fitting tongue H of the roofing material A is inserted, locked and connected. According to such a procedure, the upper, lower, left and right directions are connected, and the roof base is sequentially constructed from the eaves direction to the ridge direction.
