Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an extruded roof tile used for a roof of a large building or the like.

[0002]

2. Description of the Related Art When a roof of a building is to be roofed, a roofing board (main house, rafters) is covered with a base plate, and a large number of roof tiles are placed on the roof plate to make a roof. Conventionally, this roof tile is generally about 300 × 300 (mm) in size, and is manufactured by press molding or another method.

[0003]

Since the conventional roof tile is very small in size and it is necessary to use a large number of roof tiles to raise the roof, the work efficiency at the time of construction is poor and the mechanization of construction cannot be achieved. There are drawbacks. Moreover, since a roof tile of a small size is used, a base plate is required under the roof tile, and there is a problem in waterproofness.

In view of the above-mentioned conventional problems, the present invention has a high work efficiency during construction and facilitates mechanization of construction easily.
The purpose is to provide roof tiles with excellent waterproofness.

[0005]

According to the present invention, a plurality of hollow holes 7 in the plate surface direction are provided inside a thick plate-shaped extruded body 6, and a plurality of roof tiles are provided on the surface of the extruded body 6. Pattern part 11
Is provided.

[0006]

[Function] Since a plurality of roof tile pattern parts 11 are provided on the surface of the thick plate-shaped extruded product 6, the roof tiles can be lifted by a crane during the work, and compared to the case where small roof tiles are individually handled. It facilitates mechanization and can work quickly and efficiently. Since the plurality of roof tile pattern portions 11 are on the surface of the extruded body 6, the waterproof property is better than that when individual small roof tiles are used.

Further, since the extruded product 6 is a thick plate, it is easy to ensure the strength, and the structure can be made without the ground boards, rafters and purlins. Moreover, the extruded product 6 is provided with a plurality of hollow holes 7. As a result, the amount of material used can be reduced and the overall weight can be reduced.

It is stacked on top of the roof tile 3 of the downstream roof tile 3
The waterproof groove 14 formed on the upper side of the roof tile 3 of the upstream roof tile 3
12 covers from the upper side. As shown in FIG. 3, the butt joints of the roof tiles 3 straddle the roof tiles 3 so that the bent portions 22 at both ends enter the first drainage grooves 15 of the pair of roof tiles 3 adjacent to each other on the left and right. A joint tile 5 made of iron plate is placed on the roof tile 3, and the joint tile 5 is fixed to each roof tile 3 with a screw 24. The screw 24 is screwed into a resin spacer 25 inserted in the nut 19.

The size of the roof tile 3 is, for example, 50 to 60 in thickness.
(Mm), width 600 to 1000 (mm), length 2000 to 4000 (mm). The truss span between the roof trusses 1 is, for example, 1000 or 2000 (mm). When the roof is being constructed using the roof tile 3 with the above configuration, the nuts at the four corners 19
A hoisting hook is screwed onto the roof tile 3 and the roof tile 3 is hoisted on the roof truss 1 in a small upright state by a crane or the like, and the truss beam 2
