Abstract

PURPOSE: To reduce weight, increase strength, enhance waterproofness and further enhance the degree of freedom for shape by installing a fiber reinforced plastic. CONSTITUTION: A refractory board, such as asbestos cement board is fixedly mounted on the top of a structural plywood fixed with a framework structural body, such as a beam wherein a fiber reinforced plastic (FRP)-made layer 7 is installed to the top of the board. Then, a primer 8, which is preliminarily coated on the board 6 as a substrate treatment material, is installed on the layer 7. A resin-made FRP under coat layer 7A is installed on the primer 8 wherein a glass fiber layer 7B is installed on the under coat layer 7A and the layer 7B is further coated to form a resin-made FRP top coat layer 7C, thereby forming a roof material 2. Then, the FRP layer having the layer 7B is installed so as to enhance the strength of the roof material 2. The resin-made under coat and top coat layers 7A and 7C make it possible to enhance water resistance and comply with free shape and reduce the weight.

2. Description of the Related Art A conventional construction method such as a wooden frame construction method, a frame construction or panel type wooden frame construction method (wooden prefabricated construction method), or a frame or panel type steel frame construction method (rebar prefabricated construction method) Roof structure of roof tiles
A letterpress or the like as known from Japanese Patent No. 100720 is used.

[0003]

In the roof tile of the prior art, the weight of the roof structure cannot be reduced because the roof tile is relatively heavy. On the other hand, there was a problem that the strength was weak in the origami plate. Further, there is a problem that the roof tiles and the folded plates are slightly inferior in waterproofness.

Therefore, an object of the present invention is to solve the above problems and to provide a roofing material that is light in weight, excellent in strength, and excellent in waterproofness, and can also improve the degree of freedom in shape.

[0005]

SUMMARY OF THE INVENTION The present invention is a roofing material provided with a fiber reinforced plastic.

[0006]

With the above construction, the fiber-reinforced plastic can reduce the weight of the roof, improve its strength, and improve its waterproofness.

It is a structural plywood having a size of mm or more, and this structural plywood 3 is fixed to a framework structure 4 such as a beam. And structural plywood 3
An attic heat insulating material 5 is provided on the lower surface of the. Reference numeral 6 is a refractory board such as an asbestos cement board fixed to the upper surface of the structural plywood 3, and a layer 7 made of fiber reinforced plastic (hereinafter referred to as FRP) is provided on the upper surface of the refractory board 6. The FRP layer 7 is made of, for example, glass fiber reinforced plastic (abbreviation GFRP), carbon fiber reinforced plastic (abbreviation CFRP), or the like. The FRP layer 7
Is preliminarily provided on the refractory board 6 with a primer 8 as a surface treatment material, and is coated on the primer 8 to provide an FRP undercoat layer 7A having a thickness of about 1 mm made of a resin, and the FRP undercoat layer 7A having a thickness of about 1 mm is provided. Is provided with a glass fiber or carbon fiber layer 7B, and a FRP topcoat layer 7C made of a resin and having a thickness of about 1 mm is further applied on the layer 7B.

Therefore, the roofing material 2 is formed by sequentially applying the structural plywood 3, the fireproof board 6, the primer 8, the FRP undercoat layer 7A, the glass fiber or carbon fiber layer 7B, and the FRP overcoat layer 7C. The FRP undercoat layer 7A, the glass fiber or carbon fiber layer 7B, the FRP
The overcoat layer 7C is formed by drying for about half a day, integrally curing, and then sequentially applied.

As described above, in the above embodiment, the roof material 2 is used.
The strength of the roofing material 2 can be improved by providing the FRP layer 7 having the reinforcing material layer 7B made of glass fiber or carbon fiber. Further, the FRP undercoating layers 7A and 7C made of resin can improve the water resistance, can be adapted to any shape, and can be reduced in weight.

FIG. 4 shows a second embodiment. The same parts as those in the first embodiment are designated by the same reference numerals and detailed description thereof will be omitted. In the second embodiment, on the upper surface of the structural plywood 3, there is provided a sheathing board 11 having a thickness of 9 mm or more, which is made of wood fiber board and has an interference material and a sound absorbing material. The upper surface of this sheathing board 11 is the same as that of the first embodiment. The FRP layer 7 is provided. Further, the top surface of the FRP layer 7 is made of an adhesive agent, and is used as a flatness adjusting material 12 for making the surface flat.
Is provided, and a refractory board 6 such as an asbestos cement board is provided on the upper surface of the unevenness adjusting material 12, and the refractory board 6 is provided.
A waterproof finishing material 13 is provided on the upper surface of the by coating or the like. It should be noted that a layer of mortar (not shown) may be provided in place of the refractory board 6, and a waterproof finishing material may be provided on the upper surface of this mortar layer by coating or the like.

Therefore, the structural plywood 3, the primer 8, the FRP layer 7, the uncontrollability adjusting material 12, and the waterproof finishing material 13 are sequentially applied in the same manner as in the first embodiment to form the roof material 2. still,
