Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a metal roof tile fastening structure.

[0002]

2. Description of the Related Art First, referring to FIG. 7, a metal roof tile 2 having the same profound feeling and design as natural stone will be described.

The metal roof tile 2 is provided with a ridge portion of the face plate portion 13 which is raised to provide a rising portion 4 which is further bent toward the ridge side to provide an upper surface portion 5. On the upper surface portion 5, there are a groove receiving portion 27 for mounting the groove 7 of the roof tile 2 on the upper step, and a suspension mounting portion 28 provided with a recess for fitting the suspension 25.

The eaves side of the metal roof tile 2 is formed by folding down the eaves side of the face plate portion 13 to form a folding down portion 11 and bending it inward to form a goby portion 12.

Further, a face plate portion 13 is provided on one side edge of the metal roof tile 2.
A hanging piece 10 is provided, and a groove 7 is provided on the other side edge. The side end of this groove 7 is raised to form a rising piece 8. The ridge side is raised and then further bent to the ridge side, and the eaves side is folded down.

The metal roof tile 2 having such a structure has just been developed, and the invention of effective construction methods and members has been awaited.

However, when the conventional roofing material construction method is applied, the metal roof tile 2 is a hat-shaped metal peg as shown in FIG.
It is possible to consider a method of mounting it on 26 and fixing it to the metal pier 26 with the fastener 24 using the suspender 25.

As shown in FIG. 8, the groove 7 of the roof tile 2 on the upper step is placed on the groove receiving portion 27 of the roof tile 2 on the lower step, and the lower step While hooking the goby portion 12 on the tip of the hanging member 25 that holds the metal roof tile 2 on the roof, cover the roof with the goby portion 12. Further, the metal tiles 2 that are adjacent to each other on the left and right are fixed to the metal piers 26 with the fasteners 24 by using the hangings 25, and the groove 7 of the metal tile 2 that has been previously roofed is covered with the metal tile 2 that is next to it. Will be constructed.

[0009]

However, the conventional method for fastening metal roof tiles has a large material cost because a large suspension is used for each metal roof tile. Also,
If the goby that is hooked on the suspension deforms, it will come off easily,
There is little sense of unity between the top and bottom metal roof tiles because the metal roof tiles are stopped at one place with the fasteners and the roof tiles are covered next to each other. I was worried. In addition, the long distance from the point where the hanger is attached to the tip is also a concern for strength.

[0010]

The present invention has the following constitution in order to solve the above problems.

First, an upper surface portion having a recess is provided on the ridge side,
The top surface of the metal roof tile, which has a groove with a rising piece on the side edge, is placed on the pier. Next, the groove of the roof tile is fitted in the recess provided on the upper surface of the roof. Then, while fixing the rising piece at the side end of the groove, the metal roof tiles on the lower step are fixed.
