The present invention relates to a corrugated roofing material characterized in that R is equal to the curvature r1 of the back surface of the ridge, and curvature R2 of the surface of the valley protrusion 40 is equal to the curvature r2 of the back surface of the valley.

Conventional corrugated roofing materials are made by forming boards of approximately uniform thickness into a corrugated shape with alternating peaks and valleys, so when these are overlapped, the peaks and valleys appear as shown in Figure 1. Cavities 5 and 5 are formed in the and valleys, respectively, which become passageways for rainwater to infiltrate after construction, and when many sheets are stacked, they wobble, resulting in poor stability, and there is no sense of weight in appearance. The present invention has been made in view of the drawbacks of the prior art, and its purpose is to provide a wave-like structure with a substantially uniform thickness that overlaps each other without any gaps by simple improvement. To provide a corrugated roofing material capable of suppressing the infiltration of rainwater, capable of stably stacking a large number of sheets, and having a neutral feeling of weight.

Embodiments of the present invention will be described in detail below with reference to the drawings.

1 is the tile itself, which is made by mixing cement with asbestos and molding it using a mold.

The tile main body 1 is a plate material of approximately equal thickness and has a corrugated shape with peaks and valleys appearing in a direction parallel to the roof edge.

At the upper end of the tile main body 1, an overlapping part 2 is formed to overlap under the tile main body 1 in an upper stage.

Mountain protrusions 3 are formed at the peaks of the waveform on the surface of the overlapped portion 20, and valley protrusions 4 are formed at the valleys.

The curvature R1 of the front surface of the crest 3 is made equal to the curvature r1 of the back surface of the ridge.

The curvature R2 of the surface of the valley protrusion 40 is made equal to the curvature r2 of the back surface of the valley.

However, the overlapped portion 2 of the corrugated roofing material 60 configured in this way
The corrugated roofing material 6 is laid on top of this on the upper level (on the ridge side).

In such a case, the peak protrusions 3 come into contact with the back side of the ridges of the upper corrugated roofing material 60, and the valley protrusions 3 contact the back side of the valley, causing the two upper and lower corrugated roofing materials 6 to form a gap as shown in FIG. (They can be stacked one on top of the other, and can reliably prevent rainwater blown up through the valleys and peaks of the corrugated roofing material 6 from penetrating.

In the embodiment, three peak protrusions 3 and three valley protrusions 4 are formed at intervals from the ridge side to the eaves side, but at least more (or more) may be formed than this.

By providing a plurality of tubes, it is possible to prevent rainwater from entering due to capillary action.

In the overlapping state, as shown in FIG.
The corrugated roofing material 6 (on the ridge side) floats up from the surface of the lower corrugated roofing material 60, giving it a sense of solidity.

Cutout portions 7.7 are formed at the lower left corner and the lower left corner of the corrugated roofing material 6.

As shown in FIG. 9, after the left and right corrugated roofing materials 6, 6 are installed on the eaves side, the cutout 7 of the lower left corrugated roofing material 6 is replaced by the cutout 7 of the upper right corrugated roofing material 6. Then, stack the left corner a of the upper left corrugated roofing material 6 on point B as shown by the arrow, and connect the butt edges of the cutouts 7 and 7 to the lower right and upper left corrugated roofing materials 6. , 6 to suppress rain leakage.

In summary, the present invention forms an overlapping part that overlaps under the upper tile main body at the upper end of the tile main body, which has a waveform in which peaks and valleys appear alternately and has a substantially uniform thickness, and the above-mentioned waveform on the surface of the overlapping part. A ridge is formed on a mountain and a trough is formed on a valley, and the curvature of the surface of the ridge is equal to the curvature of the back of the mountain, and the curvature of the surface of the trough is equal to the curvature of the back of the valley. If the main body of the tile on the ridge side is placed on top of the ridge,
The advantage is that the valley protrusions can come into contact with the back side of the valley without any gaps, and therefore, after construction, the valley protrusions and the mountain protrusions become a shield that blocks rainwater from entering, thereby suppressing the infiltration of rainwater. There is.

Moreover, since they can be stacked without any gaps, a large number of sheets can be stacked stably, and the upper corrugated roofing material can be lifted off the surface of the lower corrugated roofing material due to the crest and valley projections. This has the advantage of creating a dark, shadow-like void at the bottom of the corrugated roofing material, creating a sense of weight.
