[Problems to be Solved by the Invention] In the above-mentioned conventional roof using plate-shaped roofing materials such as natural slate, the opposing ends of the laterally adjacent roofing materials (8) are not overlapped one above the other. Rainwater, etc. enters the indoor side of the roofing material (8) from the abutting or adjacent portions of these opposing ends, which tends to cause water leakage.In order to prevent water leakage, a Even with a complicated structure, such as providing a waste plate (7) for each, there is a problem in that it is difficult to reliably prevent water leakage.

[0008] In addition, since the roofing material panel (2) fixes a large number of roofing materials (8), it is heavy and has a large area, so work at heights on the roof becomes hard work. At the same time, there was also the problem that it was dangerous.

The present invention solves the above-mentioned problems, has a simple structure, can reliably prevent water leakage, and does not require heavy labor or danger when using plate-shaped roofing materials such as natural slate or tiles. The object of the present invention is to provide a roof using a plate-shaped roofing material, which can be roofed with a small amount of work and with good workability.

[Means for Solving the Problems] A roof using a plate-shaped roofing material according to the present invention has a water leak prevention plate laid on a support member, and a drainage space above the water leak prevention plate. , a roofing material unit in which a plurality of disc-shaped roofing materials made of natural slate, tiles, etc. are fixed to an engaging member in a horizontal row is arranged, and the engaging members of the roofing material units adjacent in the direction of the eaves are engaged. At the same time, the engaging members of each roofing material unit are respectively fixed to the support member side.

[0011]

[Function] In the present invention, a water leakage prevention plate is laid on a support member such as a main building directly or via an underlying material, and mounting members such as metal rafters are fixed on the water leakage prevention plate. By supporting a roofing material unit on top, engaging the engaging members of adjacent roofing material units in the direction of the eaves, and fixing the engaging members to the mounting member, a large number of plate-shaped roofing materials can be attached. You can build a roof using

[0012] Since the roofing material unit is made by fixing a plurality of disc-shaped roofing materials in a horizontal row, the size of the roofing material and the width of the roofing material in the lateral direction are smaller than those of the conventional roofing material panels described above. If the numbers are equal, the area is small and the weight is not heavy. Therefore, since the roofing unit has a small area and is not very heavy, it does not require heavy labor and allows work at heights to be performed relatively safely.

[0013] Furthermore, the roofing material unit has a simple structure because the engaging member also serves as a connecting member for the roofing materials at multiple locations, and does not use waste boards or reinforcing bars used in conventional roofing material panels. Compared to the method of fixing roofing materials one by one to the face plates after roofing, by fixing multiple roofing materials in a horizontal row with engaging members at the factory, it is easier to work and create a plate-shaped roof. You can build a roof with wood.

Furthermore, even if water such as rainwater enters the indoor side of the roofing material from between the roofing materials, this water is caught by the water leak prevention plate and flows down to the eaves side, and is discharged from the eaves of the roof, thereby preventing the above-mentioned problem. To reliably prevent water from leaking to the indoor side of a water leak prevention plate.

[0059]

[Effects of the Invention] As explained above, in the roof using the plate-shaped roofing material according to the present invention, a water leak prevention plate is laid on a supporting member, and a drainage space is provided above the water leak prevention plate. A roofing material unit in which a plurality of disc-shaped roofing materials made of natural slate, tiles, etc. are fixed to the engagement member in a horizontal row is arranged through the engagement member of the roofing material unit adjacent to the eave ridge direction. Since the engaging members of each roofing material unit are respectively fixed to the supporting member side, the following effects can be obtained.

That is, since the roofing material unit of the present invention is a small unit in which a plurality of disc-shaped roofing materials are fixed in a horizontal row, the size and width of the roofing materials are smaller than the conventional roofing material panels described above. If the number of roofing materials in each direction is equal, the area is small and the weight is not heavy. Therefore, since the roofing unit has a small area and is not very heavy, it does not require heavy labor, and work at heights can be performed relatively safely.

[0061] The roofing material unit has a simple structure because the engaging member also serves as a connecting member for roofing materials at multiple locations, and does not use waste boards or iron plates used in conventional roofing material panels. Compared to the method of fixing roofing materials one by one to the face plates after they have been installed, by fixing multiple roofing materials in a horizontal row using engaging members at the factory,
A roof with plate-shaped roofing material can be constructed with good workability.

[0062] In addition, the roofing unit has the engaging member fixed to the mounting member, and the roofing unit on the eave side and the roofing unit on the ridge side are engaged with each other by the engaging member, so that the roofing unit is protected against strong winds and the like. Even if force is applied from the eaves side, the eaves side of the roofing material unit does not roll up, and the plate-shaped roofing material can be prevented from scattering.

Furthermore, even if water such as rainwater enters the indoor side of the roofing material from between the roofing materials, this water is collected on the leakage prevention plate and flows down to the eaves side, and is then discharged from the eaves of the roof. It is possible to reliably prevent water from leaking to the indoor side of the water leak prevention plate.
