DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a flat roofing material.

[0002]

2. Description of the Related Art A flat roofing material is a thin flat plate of a fiber-containing cement board. The roofing appearance is a flat design because the thin flat plate is shifted and polymerized, and looks poor. Therefore, in order to impart a beautiful appearance to the roofing appearance, it was invented to form the eaves-side end of the flat roofing material into a geometrically uneven shape.

In addition, in order to improve drainage at the eaves-side end of the flat roofing material, it has been invented to form the eaves-side end of the flat roofing material into a geometrically uneven shape.

[0004]

However, in the conventional flat roofing material in which the eaves-side end is formed with irregularities, the roofing appearance is a modern and geometric design, but it is an old-fashioned and traditional one. It does not look like the appearance of Japanese tiled roofing. When it comes to a design that looks like a Japanese-roofed roof, it now feels heavy and luxurious.

[0005] Further, in the flat roofing material having the eaves-side end formed with irregularities, when the corners with the irregularities are made acute angles smaller than right angles, cracks are formed at the acute corners in the curing process of the fiber-mixed cement board. Is likely to occur.

An object of the present invention is to solve the above-mentioned conventional problems.

[0007]

A Japanese tile is a corrugated plate.
The eaves-side end face of the roofing appearance has a wave shape in which many identical mountain shapes are continuous in the left-right direction. Each chevron of the waveform is smooth, with one ridge longer than the other. The longer ridgeline has a steeper slope at the foot than at the top.

When a flat roof material is provided with a mountain-shaped notch portion imitating the wavy shape of the eaves-side end of the eaves side over the entire width or almost the entire width at the eaves-side end, a large number of roofs are obtained. Isomorphic
Chevron shaped Switching Operation-out portion is arranged in a row in the lateral direction of the. When this roofing state is viewed from the ground, the top of each mountain-shaped notch portion appears to float, and a three-dimensional wave-shaped design appears as if a wave-shaped Japanese tile was roofed.

[0009]

According to the present invention, a plurality of notches having the same shape and having a gentle mountain shape are provided at the end on the eaves side over the entire width or almost the entire width, and the top of the notch is formed at a right angle. A flat roofing material characterized by having a large obtuse angle, making one of the ridge lines on both sides of the cutout portion longer than the other, and making the foot portion on the longer ridge line a gentler slope than the top portion.

[0010]

When the flat roofing material of the present invention is to be roofed, the flat roofing materials are arranged in a row in the left-right direction on the inclined roof base plate.
The upper row of flat roofing materials is arranged in the same manner, with its lower part overlying the upper part of the lower row of flat roofing materials. In addition, the flat roof members in the upper row are similarly arranged.

Then, in each row, the eaves side of the flat roofing material
A number of the same mountain-shaped notches are arranged in a line in the left-right direction. Looking up at the roofing state, the top of each mountain-shaped cutout portion appears to float, and a three-dimensional wavy design such as the appearance of the roofing of a Japanese tile appears.

[0012]

According to the flat roofing material of the present invention, when the flat roofing material is roofed, a three-dimensional wave-shaped design such as the appearance of Japanese tile roofing appears, and a heavy feeling of luxury can be obtained.

Further, the top of the notch portion, since the obtuse greater than right angles, a low possibility that cracks are generated in the manufacturing process.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A flat roofing material 1 of this embodiment is a flat plate of a fiber-mixed cement board which is prepared by dewatering a slurry of cement or wood fiber, punching it into a desired shape, press-forming, curing and curing.

The size of the flat roof material 1 is 60 c in width.
It is about m in height, about 45 cm in height, and about 6 mm in thickness.

At the lower end on the eave side, as shown in FIG. 1, cutouts 2 of the same shape are provided on the right half and the left half, respectively. As shown in FIG. 2, the notch 2 is formed in a gentle mountain shape, the top 3 is formed in an arc shape, and the top 3 is formed.
Is made obtuse, one of the left and right ridge lines 4, 5 is longer than the other, and the foot portion 6 of the longer ridge line 5 has a gentler gradient than the top portion 7.

[0017] Between the left end of the eave side end and the left notch 2, between the left notch 2 and the center position of the eave side end, and between the center position of the eave side end and the right notch. As shown in FIG. 1 and FIG. 2, a short horizontal portion 8 having no notch is provided between the right and left notch portions 2 and the eave-side end portion.
Is leaving.

The angle of the top 3 is about 150 degrees. The length of the longer ridgeline 5 is about twice that of the shorter ridgeline 4. In the longer ridge line 5, the inclination angle of the foot portion 6 is ２ of that of the top portion 7.

As shown in FIG. 1, the upper part on the ridge side has approximately one-third on the left side and about one-third on the right side formed to descend left and right, respectively.

When the flat roofing material 1 is to be roofed, as shown in FIG. Are arranged in a row, and the flat roofing material 1 in the row above
With the lower part over the upper part of the flat roofing material 1 in the lower row,
In addition, they are arranged in the same manner as the lower row by being shifted from the flat roof material 1 in the lower row by a half width in the left-right direction. Further, the flat roof members 1 in the upper row are similarly arranged.

Then, as shown in FIG. 3, the cutouts 2 provided at almost the entire width at the eaves side end of the flat roofing material 1 in each row are arranged in a line in the left-right direction at equal intervals. Each cutout 2 in the row is disposed directly above each cutout 2 in the row below.

Looking up the roofing state from the ground,
The top of each notch appears to float, giving rise to a three-dimensional wavy design that looks like a wavy tile roof tile.

[0023] <Modification> 1) Example flat roofing material 1 of the chevron-shaped notch 2 is provided over substantially the entire width at the end portion of the eaves side is arranged two right and left, 3 Pieces or four pieces are arranged at equal intervals.

2) In the flat roofing material 1 according to the embodiment, the notch 2 is provided between the right or left end of the eave-side end and the notch 2 and the center of the eave-side end is provided with the notch 2. The short horizontal part 8 which is not missing was left, but the horizontal part which is not notched is not left at the eaves side end. In other words, the notch 2 having a mountain shape is provided over the entire width of the eave-side end.
