[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a staggered flat roof tile that prevents rainwater from intruding from the overlapping portions on the left and right sides and enhances the shadow contrast during the roofing.

[0002]

2. Description of the Related Art Conventionally, flat roof tiles are abutted on both left and right sides of a superposed portion having a rainwater escape groove, and left and right positions of the lower flat roof tile are alternately erected by a half width of the flat roof tile. , So-called staggered roofing, and in such a flat tile, rainwater flowing down the running surface of the upper flat tile is randomly flowed down by the wind to the lower flat tile, or concentrated in one place. Then, a large amount of water flows down to the overlapping portion of the lower flat roof tile, and the rainwater escape groove provided in the overlapping portion does not sufficiently perform the drainage function, resulting in frequent leakage of rain.

[0003]

SUMMARY OF THE INVENTION The present invention eliminates the concentrated flow down to the overlap section in the girder direction and reduces the reverse flow velocity of rainwater in multiple stages to prevent rain leakage from the overlap section in the girder direction and the flow direction. It is intended to provide a flat roof tile which prevents the above-mentioned phenomenon and which makes the shadow contrast of the surface clear by the guiding portion and improves the appearance of the roof surface.

[0004]

SUMMARY OF THE INVENTION In view of the problems such as infiltration of rainwater into the superposition section and backflow based on the above-mentioned prior art, the present invention prevents rainwater from concentrating in the central part of the running water surface and The above-mentioned drawbacks are not solved by providing a flat roof tile, which has a gist of forming a step-like water repellent.

As the flat tile, a flat tile in which both sides are butted against each other in a zigzag manner is provided at a substantially central portion of the running water surface, and a stepwise central protruding portion is formed at a substantially central portion of the flowing water surface as it moves from the hip side to the head side. The left central protrusion and the right central protrusion, which are similar to the central protrusion, are also formed at the substantially central portions of the flowing water surface on both sides of the central protrusion, and the central protrusion and the left protrusion are formed. In the running water surface except the central protruding part and the right central protruding part,
A guide portion is formed which is inclined downwardly toward the base side of the left central protruding portion and the right central protruding portion via the paragraph portion as it moves from the hip side to the head side.

[0006]

In the present invention, the rainwater flowing down from the upper flat roof tile is guided to the base side of the left central protruding portion and the right central protruding portion by the inclined guiding portion on the upper surface, and the rainwater is blown up by the wind. For the reverse flow, the flow rate of rainwater is reduced in multiple steps by the paragraphs of each guide, and the inclination angle of the top surface of the guide is alternately changed to change the reflection angle of light and clarify the shadow contrast. To do.
