Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a roof tile structure in which a large number of roof tiles are arranged side by side on a roof, and more particularly to a technique for preventing water leakage at a roof tile overlapping portion.

[0002]

2. Description of the Related Art As a conventional roofing tile structure, a Japanese roof tile 51 shown in FIG. 10A, an S-shaped roof tile 61 shown in FIG. 10B, and a flat plate shown in FIG. Those using the roof tile 71 are known. Japanese roof tile 51 and S-shaped roof tile 61
In the case of 1, since the main body portions 52 and 62 are curved and rainwater flows down there, there is little risk of water leakage in the overlapping portions 53 and 63. On the other hand, in the case of the flat roof tile 71, the main body 72
Is molded in a flat plate shape and the joint 73 is exposed, so that rainwater overflowing from the main body 72 may leak to the roof material (lowering material) through the polymerizing portion 74, especially when there is a large amount of rain. There is.

In view of this, Japanese Utility Model Registration No. 3009222 proposes a technique for suppressing water leakage in the overlapping portion of a flat roof tile. As shown in FIG. 11, this flat roof tile 8
1, the main body portion 82 is formed in a flat plate shape, and the overlap portion 83 and the underlap portion 84 are provided on both left and right sides thereof. A stopper 85 is integrally projectingly provided at the base of the underlap portion 84, and a drain groove 86 is formed outside the stopper 85. Then, part of the rainwater W that has entered from the joint portion 87 is made to flow down along the stopper 85, and the rainwater that has passed over the stopper 85 is drained along the drainage groove 86, and the water leak from the overlapping portion 88 to the roof material side. It can be suppressed.

[0004]

However, according to this roofing structure, since the stopper 85 is not in close contact with the overlap portion 83, the overlapping portion 88 cannot be sealed,
When a large amount of rainwater W flows over the stopper 85 and flows into the drainage groove 86, the water overflowing from the drainage groove 86 leaks to the roof material side. Further, since the stopper 85 is integrally formed with the underlap portion 84 by a fragile material, even if the stopper 85 is projected at a height so as to abut the overlap portion 83, the stopper 85 may be formed due to a molding error, a construction error, a defect, or the like. A gap is likely to be formed between the undercoat portion 85 and the underlap portion 84, and the water-stopping effect cannot be expected so much.

The present invention has been made in view of the above problems, and an object of the present invention is to provide a roof tile structure capable of reliably preventing water leakage by hermetically closing a polymerization portion.
