Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile that is lined up in a roof field and a structure for laying the roof tile.

[0002]

2. Description of the Related Art FIG. 13 shows a typical example of a conventional tiled roof that is roofed with a tile plate. On the upper surface of the tile plate 21 used for this tiled roof, a ridge portion 22 which is convexly bent upward in the vertical direction, and a groove portion formed as a flat portion between the ridge portions 22 are formed. 23 and 23 are formed alternately in the lateral direction, and are formed on the lower surface of the roof tile plate so that they can be overlaid on the upper surface without any gap.

In the tile roof using the above-mentioned tile board 21, another tile board 21 is laid on the ridge side of the tile board 21 which has been laid in advance. 22 must be aligned with the ridges 22 of the roof tile 21 that has been laid first, and the positions of the recessed grooves 23 cannot be shifted to the left and right and cannot be overlaid. For example, it was not possible to form a tile roof having a different taste such that the protrusions 22 of the tile plate 21 laid on the ridge side are arranged in the concave groove portions 23 of the tile plate 21 laid on the eaves side. Also,
The position of the roof tile 21 that is piled up on the ridge side in the left-right direction is the ridge portion 2.
Since it is regulated by 2 and the recessed groove portion 23, for example, a tile plate facing the valley ridge, a building tile of the alighting ridge, or a tile plate connected to the glazed accessory is cut at an arbitrary position. However, the end material of the roof tile to be cut is wasted.

Therefore, the applicant of the present invention is a roof tile that solves the above-mentioned problems of a tile roof using a conventional tile board and allows a tile board that is vertically stacked to be stacked at any position in the left-right direction. Has been previously proposed by, and an example thereof is shown in FIGS. The roof tile 31 used for this roof tile is formed by arranging a vertically oriented ridge 32 and a recessed groove 33 opened toward the eaves side by side on the surface thereof, and the upper surface of the ridge side end is The eaves side end of another tile plate 31 laid on the ridge is formed on the ridge-side flat surface 34 on which the eaves can be placed. In addition, this roof board 3
One of the left and right ends of 1 is formed with the lower receiving portion 35 on which the other end of the tile plate 31 that is laid adjacently can be placed, and the tile plate 31 that is laid adjacent to the other is formed. An upper overlapping portion 36 that can be placed on the lower receiving portion 35 is formed to form an eye contact portion a that can overlap each other.

[0005]

According to the above proposed roof tile, it is possible to stack another tile plate 31 at an arbitrary position on the ridge side of the tile plate 31 laid on the eaves side, and further,
Since the concave groove portion 33 of the roof tile 31 on the eaves side is formed lower than the ridge-side flat surface 34, rainwater flows into the concave groove portion 33 at the time of rainfall, and the water climb to the ridge-side flat surface 34 is suppressed. Furthermore, at the left and right end portions of the tile plates 31 that are adjacent to each other on the left and right,
Although the rainwater is prevented from leaking by the eye contact portion a formed by being overlapped with each other, which is excellent in usability, it has the following problems.

That is, according to the proposed roof tile, the left and right end portions of the roof tile plate 31 require a stacking margin in order to form the eyelid portion a, and moreover, the width in the left-right direction of these stacking margins is large. A certain size is required, and for this reason, a large amount of material is required to form the eye contact portion a. Further, in order to sufficiently exert the waterproof function of a in the eyelid portion, it is desirable to form the water guide groove 37 in the lower receiving portion 35, and therefore, the lower receiving portion 35 has a thin fragile portion. The strength tends to decrease, and the lower receiving part is liable to be damaged or chipped during transportation, storage, or construction, and the handling must be done with caution.

The present invention has been made in view of such a point, and in constructing a roof tile that can be freely roofed and piled up, by eliminating the eye jacquard portion, the material used can be saved. The purpose is to make it easy to handle and to eliminate the fragile portion.
