Description

[Detailed explanation of the invention] [Purpose of the invention] Industrial field of application The invention is a flat tile for staggered roofing, which prevents rainwater from entering from the overlapping parts on the left and right sides, and which is designed to prevent geometrical problems during roofing. This relates to flat tiles that form patterns to create an attractive roof surface.

Conventional technology Conventionally, flat tiles have been constructed in such a way that the right and left sides of the overlapping part having rainwater drainage grooves are brought into contact with each other, and the left and right positions are alternately installed on the bottom side of the lower flat tile by half the width of the flat tile. The roofing is staggered, and with such flat tiles, rainwater that flows down the running water surface of the upper flat tiles is randomly flowed down to the lower flat tiles by the wind, or it is scattered in one place. A large amount of rainwater is concentrated and flows down to the overlapped part of the lower flat tiles, and the rainwater drainage grooves provided at the overlapped part cannot sufficiently perform the drainage function, resulting in frequent rain leaks.

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 in order to prevent rainwater flowing down from the upper flat tile from concentrating on the overlapping parts on the left and right sides, it flows toward the center of the water surface of the lower flat tile. At the same time, by discharging rainwater to the center side through the rainwater guiding part of the lower flat tile, the concentrated flow of rainwater to the overlapping part is eliminated, and rain leakage from the overlapping part is prevented, and this function is achieved. By doing so, it is possible to eliminate the need to be concerned about the dimensional accuracy of the overlapping part, which improves the work efficiency and yield of manufacturing, and also allows the formation of a geometric pattern during roof installation, creating an attractive roof surface. We aim to provide flat tiles that can

[Structure of the idea]

Means for Solving the Problems In view of the above, the present invention provides a flat tile that forms projecting walls on three sides other than the head side of the flowing water surface, and has a substantially semi-elliptical shape in plan view that is symmetrical with respect to the center line of the flowing water surface. Alternatively, the shape of the substantially triangular, substantially U-shaped, or substantially polygonal groove in plan view is gradually enlarged as it is displaced from the head side to the buttocks side, and at least one or more grooves are carved therein, and at least one groove is carved at both ends of the groove. The drain port is located at the head end of the water surface, and a recess is carved between the outermost groove and the projecting wall, so that the outer and inner sides of the groove have a substantially semi-elliptical or substantially triangular shape in plan view. It forms a roughly U-shaped or roughly polygonal jetty, and in the recess of the lower flat tile that overlaps during staggered roofing, the upper end is further inward from the drainage port of the groove from the center of the upper flat tile. The above-mentioned drawbacks are solved by providing a flat tile in which a groove-shaped rainwater guiding part is formed between the projecting wall and the outermost jetty, with the lower end facing the center of the flowing water surface and diagonally provided. That is.

Function: In the present invention, by forming flat tiles in a zigzag pattern, the rainwater flowing down from the head side of the upper flat tiles is distributed to the left and right and flows down into the concave part of the water surface of the lower flat tiles, The rainwater in the recess is guided in a downward direction toward the groove on the water surface by a rainwater guide provided in the recess, thereby allowing the rainwater to flow down from the groove.

Furthermore, in response to backflow of rainwater due to wind blowing up from below, the flow velocity of rainwater is reduced in multiple stages by the jetty formed with the groove.

In addition, the grooves and jetties of each flat tile form a geometric pattern during staggered roofing.
