Description

[Detailed description of the invention] The present invention is based on the flat roofing material 1 whose upper side 1a is curved and whose lower side 1b is straight. A flat plate roof is formed by overlapping each other with a distance h, and from the lower side 1b to the upper side 1a of each flat plate roofing material 1.
A plurality of grooves 2a to 2d facing each groove 2a
The grooves 2a to 2d are formed so that the intervals between them are different, and the lengths la to ld of the grooves 2a to 2d are different. This relates to a flat plate roof in which the distances ha to hd are each set to be larger than the minimum overlap h, and its purpose is to create a flat plate roof that changes the roof appearance without impairing waterproofness. Our goal is to provide the following.

Examples will be described below using figures. 1st
The figure and FIG. 2 show an embodiment of the present invention.
1 is a flat roofing material, and the upper side 1a of the flat roofing material 1
is curved, and the lower side 1b is straight. This flat roofing material 1 is installed so that the lower part of the upper flat roofing material 1 is overlapped with the upper surface of the lower flat roofing material 1 with an appropriate minimum overlap h to form a flat roof. Cut grooves 2a to 2d are formed in the flat roofing material 1 from the lower side 1b to the upper side 1a, with different intervals between the cut grooves 2a to 2d. However, in the embodiment, the cut groove 2a is formed by the notch 3 provided on the side end surface and the side end surface 4 of the lateral flat roofing material 1. Each of these cut grooves 2a to 2d
The groove lengths la to ld are set such that the distances ha to hd between the upper ends of the cut grooves 2a to 2d and the upper side 1a of the lower flat plate roofing material 1 are each larger than the minimum overlap h.

The present invention is configured as described above, and the groove length of the cut groove bored from the lower side of the flat roofing material toward the upper side is the upper end of the cut groove and the upper edge of the flat roofing material arranged below. By making the distance between the roof and the roof larger than the minimum overlap, it is possible to prevent rainwater from entering the attic through capillary action from the grooves where rainwater tends to accumulate.
In addition, rainwater that is accelerated by the notch and rises rapidly during a rainstorm does not enter the attic from the top of the notch and impair its waterproof properties. By providing this cut groove, the waterproofness is not impaired, and by providing this cut groove, a so-called wood shingle-like roof appearance can be obtained, and the spacing between the multiple cut grooves is different. Since the groove length of each cut groove is different, even if a wide and large flat plate roofing material is used, it can have a variety of subdivisions, as if it were covered with small tiles of different sizes. This makes it possible to obtain a flat plate roof that is different from the flat plate roofs that are generally used.

[Brief explanation of the drawing]

FIG. 1 is a top view of a flat roofing material used in an embodiment of the present invention, and FIG. 2 is a top view of the main parts of the same. 1 is a flat roofing material, 1a is the upper side, 1b is the lower side, 2
a to 2d are cut grooves.

Claims (1)

[Scope of utility model registration request] A flat roofing material whose upper side is curved and whose lower side is straight is laid so that the lower part of the upper flat roofing material overlaps the upper surface of the lower flat roofing material with an appropriate minimum overlap. A roof is formed, and a plurality of cut grooves are formed from the bottom side to the top side of each flat roofing material with different intervals between the cut grooves, and the groove length of each cut groove is made different. A flat plate roof formed by setting the distances between the upper ends of the grooves and the upper sides of the lower flat plate roofing material to be each larger than the minimum overlapping allowance.
