Description

[Detailed description of the invention] [Purpose of the invention] Industrial field of application The invention is a flat plate tile for staggered roofing, which prevents rainwater from entering from the left and right sides and the upper and lower overlapping parts, and also prevents rainwater from entering from the left and right sides and the upper and lower overlapping parts. This relates to a flat tile that forms a geometric pattern to create an attractive roof surface.

Conventional technology Conventionally, flat tiles are installed so that the right and left sides of the overlapping part having rainwater drainage grooves are butted together, and the left and right positions are alternately installed by half the width of the flat tile on the bottom side of the lower flat tile. The roof is staggered, and with such flat tiles, rainwater that falls down the running water surface of the upper flat tile is randomly flowed down to the lower flat tile by wind, etc., or is concentrated in one place. A large amount of water flows down to the overlapping part of the lower flat tiles, and the rainwater drainage groove installed at the overlapping part is not able to perform its drainage function sufficiently, resulting in frequent leaks, and is also fanned by wind from below. Although rainwater that flows backwards is mainly prevented from entering by using a projecting wall on the rear side and a water return projecting in front of the projecting wall, such a structure cannot sufficiently prevent rainwater from leaking. Also, because the hanging part on the head side of the upper flat tile is in close contact with the flowing water surface of the lower flat tile, rainwater intrudes into the overlapping part due to the capillary phenomenon at this point, causing rain leakage. It was the cause of this.

In addition, in order to prevent rain from leaking from the polymerization zone, the dimensions of the polymerization zone must be manufactured with high precision, and skill is required to control the process of preparing the clay, molding, drying, and firing. However, it had drawbacks such as extremely poor work efficiency and yield.

Problems to be Solved by the Invention The present invention is a flat tile for staggered roofing, and the rainwater flowing down from the upper flat tile is directed toward the center of the water surface of the lower flat tile so that it does not flow concentrated to the overlapping parts on the left and right sides. By doing so, it is possible to eliminate the concentrated flow of rainwater to the overlapped part and prevent rainwater from leaking from the overlapped part.In addition, the rainwater that flows backwards from the head side due to strong winds can be diverted from side to side by the dispersion part of the groove. By dispersing and smoothly flowing downward, it is possible to prevent rain from leaking from the tail side, and a gap is formed by the groove at the point where the hanging part on the head side of the upper flat tile and the water surface of the lower flat tile come into contact. Therefore, it is possible to eliminate the capillary phenomenon in such areas and prevent the infiltration of rainwater, and by having such a function, it is possible to eliminate the need to be concerned about the dimensional accuracy of the overlapping part, which improves work efficiency in manufacturing. It is an object of the present invention to provide a flat tile that can improve the yield, etc., and also forms a geometric pattern to create an attractive roof surface when installed.

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention is designed to form a flat tile that forms a jetty on three sides other than the head side of the flowing water surface, and is symmetrical with respect to the center of the flowing water surface, and is approximately semi-elliptical or approximately semi-elliptical in plan view. Triangular, substantially U-shaped, substantially polygonal, and the slope is formed in a downwardly sloping shape from the center of the head side to the periphery, and the width of the groove portion is gradually widened as it moves from the head side to the buttocks side. At least one or more grooves are carved, and the drainage ports at both ends of the groove are located on the head side edge of the flowing water surface, while a recess is carved between the outermost groove and the jetty on the outer side of the groove. The above-mentioned drawbacks are solved by providing a flat tile in which a guide bank is formed inwardly in a substantially semi-elliptical shape, a substantially triangular shape, a substantially U-shape, or a substantially polygonal shape in plan view.

Function In this invention, by constructing the flat tiles in a staggered manner, rainwater flowing down from the head side of the upper flat tiles is distributed to the left and right by the grooves and flows toward the center of the water surface of the lower flat tiles. let

In addition, by directing the slope of the groove from the inner side (the head side) to the outer side (the bottom side) of the dike base, and then diagonally downward at a predetermined angle, the rainwater flowing down flows smoothly along the dike base side. In addition, a gap is formed by the groove at the contact point between the hanging part on the head side of the upper flat tile and the flowing water surface of the lower flat tile, and the groove of each flat tile creates a geometric gap during staggered roofing.
