Description

[Detailed explanation of the idea] This invention relates to flat roofing materials.

As flat roofing materials, those with a triangular apex at the head and square-shaped legs are widely known, but these roofing materials are thin, so It lacks a sense of solidity compared to a roof made of Japanese or Western tiles, and also has the disadvantage that the roofing pattern of the flat roofing material placed on the roof is parallel and linear, lacking in aesthetic appeal.

Therefore, as shown in Fig. 1, the lower side A of the flat roofing material A is
’, cut C into a slit that reaches the overlapping part B of the tile A.
Various attempts have been made to change the level of the lower end of the lower side portion A' divided by the notch C to vary the roofing pattern and give the roof an attractive appearance.

However, even if the above-mentioned roofing materials can vary the roofing pattern, they are not sufficient to give a sense of solidity.

Therefore, attempts have been made to form the edges of the legs of the roofing material obliquely toward the surface side, as shown in Figure 2, A1. , as shown by the chain lines in FIG. 1, the lower row roof material L1 and the upper row roof L
Since a groove having a V-shaped cross section is formed by the side edges of the roofing material that are lined up with both ends in contact with each other, there is a drawback that rain leakage occurs due to wind pressure.

Therefore, when roofing is layered as shown in the diagram, the only part that has sloped edges must be exposed to the outside, and in this case, the width of the roofing material is limited to one. First, there is a problem that there is no flexibility in the roofing work and the work becomes sluggish.

In view of the above, this idea was developed to "satisfy the sense of solidity, and the pattern does not change even if the roofing allowance is changed.
``In addition, it was made for the purpose of providing a flat roofing material that does not have difficulty in roofing construction, and has a slit-shaped cut at the lower part of the leg, and the periphery of the cut and the leg part. The end surface of the outer peripheral edge of the slanted surface is sloped toward the surface side, and the portion of the slope corresponding to the selvedge portion on both sides of the leg is such that the width of the slope increases from the lower end of the selvedge portion toward the upper end. It is characterized by a narrow structure.

Next, this invention will be explained using examples.

FIG. 3 is a plan view of an embodiment of this invention, and FIG. 4 is a sectional view taken along the line rV-IV in FIG.

The flat roofing material 1 of this invention has a triangular head 11, a leg 12 with slit-like cuts 2, 2 on the lower side, and a lower side 12A divided by the cuts 2, 2. , 12A (7) The button has a shape with changed levels, and has a pentagonal shape, and the edges of the notches 2 and 20 of the leg part 12, the lower side parts 12A, 12A, and the end faces of the side edges 12B, 12B. It is a slope 3 on the front side, and the width S of the slope is narrowed so that it starts from the lower end of the roofing part t of the leg portions 12B, 12B of this slope 3 and disappears at the upper end. .

FIG. 5 shows a usage state diagram of the embodiment of this invention, and when the roofing material 1 is laterally arranged side by side,
The V-shaped structure 3 formed by the slope 3 of B and the roofing allowance t
It is formed so that it narrows and terminates at the upper end.

Also, during roofing construction, the side edge 12B of the slope 3
, 12B is the upper end of the roofing allowance, so it can also be used as a mark for positioning.If you want to change the roofing allowance, for example, as shown by the chain line in FIG. Even if the upper tile L2 is shifted upward to shorten the length, the slope 3 ends with a gentle slope, so even if the roofing allowance is changed, there is almost no change in the appearance of the V-groove due to this change. It is.

Since this invention is configured as described above, the V between the roofing material side edges 12B and 12B caused by butting each other
The character-shaped grooves begin at the overlapping part of the roof and gradually become shallower and narrower until they end, so they can effectively prevent the intrusion of rainwater, and can also be used to change the covering allowance of roofing materials. However, since there is almost no change in the roofing pattern, there are no strong requirements for strictness in the work, and it is possible to have a wide range in the selection of the roofing allowance, making construction easier. It has practical effects.
