Abstract

PURPOSE:To prevent the intrusion of a rainwater from a superposed position by reducing the rainwater flow speed by installing a plurality of uneven water draining-off parts in the longitudinal, lateral and aslant directions for the rainwater flow-down direction, onto the surface of a roof tile. CONSTITUTION:The rainwater flow speed to an insertion side 6 due to the wind supplied from the lateral direction of a tile body 2 is attenuated by installing a plurality of recessed, projecting, or uneven water draining-off parts 8 and 8a in the same direction for the rainwater flow-down direction on the surface 13 of the tile body 2. Further, in the superposed state with other roof tiles 21, a plurality of uneven water draining-off parts 8 and 8a are installed at the position along the edge parts on the head side 3 and the crosspiece side 18 of the roof tile and the position separating by a prescribed interval from the edge part. Further, the uneven water draining-off parts 8 and 8a are formed in the aslant direction and perpendicular direction for the surface 13 of the tile body 2. Thus, the intrusion of rainwater is prevented, and the water draining-off parts 8 and 8a can be used as a foot hold for a laborer.

Description

[Detailed Description of the Invention] (Object of the Invention) The present invention prevents rainwater from entering during strong winds, is less slippery than conventional tile surfaces, and is easy to create images. This is about the roof tiles that can be made.

Traditionally, gentle slope roofs, which have excellent lighting, small length in the flow direction of the roof surface, and small M root weight, are advantageous in terms of costs such as materials and labor, and also have low wind pressure. Due to its small size, it has various advantages such as being strong against wind, etc., so designs for gently sloped roofs have become mainstream, and the roof tiles used for such gently sloped roofs are installed on the bottom side. Preventing rainwater from flowing back to the sides was mainly done by means of water spouts protruding from the edges of the butt and insertion sides.

However, since a large amount of rainwater accumulates in the valleys between the Ws, this rainwater can be stirred up by strong winds and run across the flat tile surface without any resistance, infiltrating past the water return.
In addition, the protrusion height of the water return is limited due to the relationship with other roof tiles that are superimposed on it, so it cannot sufficiently prevent rainwater from entering, and furthermore, in the event of strong winds and rain such as a typhoon, the height of the roof tiles that overlap is limited. Rainwater may infiltrate along the back surface of the device, and conventional water return only has the disadvantage that it cannot completely prevent rainwater from entering during strong winds and rain.

The present invention provides a large number of uneven water returns on the surface of the tile to attenuate the reverse flow velocity of rainwater in all directions vertically, horizontally, and diagonally during strong winds and rain in a multi-stage manner. It is an object of the present invention to provide a roof tile that reliably prevents rainwater from entering the roof tile and also prevents the roof tile from falling due to the uneven water return.

[Structure of the invention]

In view of the above, the present invention is designed to reduce costs by providing a plurality of concave or convex or uneven water returns on the surface of the tile main body in the same direction with respect to both water flow directions, or a tile. Although it is on the main body surface, when it overlaps with other roof tiles, it is placed along the edge of the head side and column side of the roof tile, and at a predetermined interval from the edge, in both water flow directions. tiles with multiple concave, convex, or uneven water returns in the direction perpendicular to the roof; Roof tiles that are provided with a return, or those that have a plurality of concave, convex, or uneven water returns on the surface of the tile main body in a direction perpendicular to both water flow directions, and roof tiles that are a combination of the above water returns. The present invention is intended to solve the above-mentioned drawbacks.

Tachi-ri In the present invention, a large number of irregular water return surfaces provided on the surface of the tile body are arranged vertically, horizontally, and diagonally with respect to the downward direction of the water flow, thereby attenuating the force of the wind and preventing backflow. Vertical,
By attenuating the flow velocity of rainwater in all horizontal and diagonal directions in multiple stages, and by providing water returns along the head and side edges of the upper roof tiles, especially at the overlapping points, rainwater from such points can be reduced. This prevents the infiltration of water and allows the above-mentioned water return to be used as a foothold for workers.

Next, to explain the function of the roof tile according to the present invention, there are a large number of uneven water returns 8.8a arranged on the surface 13 of the tile main body 2 in parallel, lateral, and diagonal directions with respect to both water flow directions.
This attenuates the force of the wind, and also attenuates the flow velocity of reverse flowing rainwater in all directions vertically, horizontally, and diagonally in a multi-stage manner.
By providing a water return 8.8a... across the edge of 8, it is possible to prevent rainwater from entering from such a place, and the water return 8.8a... can be used as a foothold for workers. It is possible.

〔Effect of the invention〕

In short, the present invention provides the surface 13 of the tile main body 2 with a plurality of concave, convex, or uneven water returns 8.8a in the same direction with respect to both water flow directions. The flow velocity of rainwater pushed toward the insertion side 6 by wind from the side is attenuated in multiple stages to prevent rainwater from being blown not only in the trough 7 but also in one place and concentrated and infiltrating into the overlapping part. Done,
In addition, the water return 8.8a... serves as a foothold for workers and prevents them from falling off, improving construction safety, and also functions as a snow stopper by retaining snow. It is possible to

In addition, although it is the surface 13 of the tile main body 2, when it is overlapped with another roof tile 1, a predetermined interval is provided along the edge of the roof tile 1 on the head side 3 and side side 8] and at a predetermined interval from the edge. Since a plurality of concave, convex, or uneven water returns 8.8a are provided at the positions perpendicular to the direction of both water flows, the same effect as above can be achieved, and the entire overlap area can be Rainwater pushed in by the wind can be dispersed and dammed,
Also, the displacement of the roof tiles 1 in the vertical and horizontal directions can be controlled by the return water 8.8a.

Also, on the surface 13 of the tile main body 2, a plurality of concave, convex, or uneven water returns 8.8a are provided in diagonal and perpendicular directions with respect to both water flow directions, so that the same as above. Since the above-mentioned water return 8.8a... is combined, the shape of the water return 8.8a... can be changed to a letter,
By forming numbers, pictures, etc., it is possible to give the roof tile 1 an impressive characteristic, and it is also possible to use the roof surface as a promotional medium for advertisements, etc., and it is possible to construct an innovative roof surface. Its practical effects are enormous.
