Description

[Detailed Description of the Invention] (Industrial field of application) The present invention relates to a draining shape of a flat roof tile capable of exhibiting a feeling of small division.

(Prior Art) In the past, a large number of small flat tiles were laid up to give a small cracking feeling. The drainage ridge (a) of the flat roof tile body was provided in a closed state as shown in FIG.

(Problems to be solved by the invention) In the past, a large number of cement-based flat roof tiles had to be installed in the roof, which required a lot of work, and the draining ridges were also closed. It was impossible to drain rainwater.

The present invention has been made to solve the above-mentioned problems, and the purpose thereof is to make it possible to exhibit a small cracking feeling that only one piece is laid and that a plurality of pieces are laid. In addition, the drainage ridge 6
The purpose of the present invention is to provide a flat roof tile which is drained even if rainwater crosses over the drainage ridges 6 and is dammed by the water.

(Means for Solving the Problem) The flat tile A of the present invention has kerfs along the side end faces on both sides of the exposed portion 1 of the flat tile main body 3 including the exposed portion 1 at the front portion and the overlapping portion 2 at the rear portion. 4a and 4b are provided, and cut grooves 4c and 4d are provided from the front end toward the rear in the middle part of the exposed portion 1 as well. Water drainage ridges 6 are provided, and both front ends of the concave grooves 7 between the water drainage ridges 6 are bent outward so that they are opened at the side end faces of the overlapping portion 2, respectively, and the cut grooves 4a, 4b of the side end faces are formed. This is an attempt to solve the above problems by bringing the rear end close to the rear end.

(Operation) The cut grooves 4a, 4b, 4c, 4d can give an appearance that shows a small split feeling that a large number of flat tiles A are being laid when one flat tile A is laid. The workability is excellent, and even if rainwater enters the concave grooves 7 between the drainage ridges 6, the flat roof tile A
The drainage is intended to be performed in the direction of the cut grooves 4a and 4b, which are the joints of the side end faces of the. That is, the rainwater that has entered the concave groove 7 has a high flow velocity in the front-rear direction portions on both sides of the concave groove 7, but the flow velocity is relaxed at the bent portions of the front ends of the concave groove 7 and the contact point with the adjacent flat tile A. The rainwater is guided to the portion and gently collects in the gaps of the contact joint portion or the gap between the contact tile portion and the flat roof tile A laid on the contact joint near the upper ends of the cut grooves 4a and 4b. As a result, most of it is discharged into the cut grooves 4a and 4b, and the cut grooves 4a and 4b
Rainwater after being discharged inside is smoothly drained and removed forward. In addition, in the joint portion between the adjacent flat tile A in the exposed portion 1 of the flat tile A, the groove width is widened due to the presence of the cut grooves 4a and 4b, and the capillary phenomenon does not occur. Of rainwater is prevented.

(Embodiment) An embodiment will be described below with reference to FIGS. 2 to 4 according to an embodiment of the present invention.

A is to provide cut grooves 4a and 4b along the side end surfaces on both sides of the exposed portion 1 of the flat tile main body 3 made of cement or the like, which is composed of the exposed portion 1 at the front portion and the overlapping portion 2 at the rear portion, and is overlapped. A plurality of draining ridges 6 are provided along the rear side and both sides of the mating portion 2, and both front ends of the concave groove 7 between the water draining ridges 6 are bent outward to form the overlapping portion 2 It is a flat roof tile that is opened on each side end face and is close to the rear ends of the cut grooves 4a and 4b.

At this time, two cut grooves 4c, 4d are formed from the front end of the exposed portion 1 of the flat roof tile main body 3 toward the rear to form three divisions, and the slit widths of the cut grooves 4c, 4d are provided on the side end faces. It is formed to have twice the slit width of the cut grooves 4a and 4b.
Further, the exposed portion division body 1a on the left side portion is formed shorter than the other division bodies 1b and 1c. The reference front end line b crosses the guide portion 8 of the cut groove 4d on the short side, and the front end of the flat plate tile main body 3 at the rear portion is overlapped along the reference front end line b during construction. The corners at the front end of each divided body 1a, 1b, 1c are notched to form a notched portion 9 so that each divided body 1a, 1b, 1c has a separate and independent appearance when overlapped. ing.

A plurality of draining ridges 6 are formed on the peripheral portions on the rear side and both sides of the overlapping portion 2, and alignment marks are formed on the rear end portion and the central portions of both end portions of the overlapping portion 2. 10 are formed.

Thus, the flat roof tile A is nailed and fixed to the roof base through the nailing holes 11 at the time of construction, and then the reference front end line b
Also, the front portion of the flat tile A on the upper stage is superposed on the overlapping portion 2 with the alignment mark 10 as a mark, and is sequentially erected. In this way, it is possible to give the appearance that the flat tile A is laid and a large number of small tiles are laid by the exposed portion divided bodies 1a, 1b, 1c, and the contact joint portion of the flat tile A is provided. In the above, the rainability and drainage are improved. Further, in this case, the rainwater that has infiltrated upward and rearward along the surface of the flat roof tile A is dammed up by the water draining ridges 6 to be waterproofed, and rainwater that has passed over the water draining ridges 6 should also be drained ridges 6. The water is smoothly removed into the cut grooves 4a and 4b which enter the recessed groove 7 between them and are the contact joints of the side end surfaces of the flat tile A. That is, the rainwater that has entered the concave groove 7 has a high flow velocity in the front-rear direction portions on both sides of the concave groove 7, but the flow velocity is relaxed at the bent portions of the front ends of the concave groove 7 and the contact point with the adjacent flat tile A. The rainwater is guided to the portion and gently collects in the gaps between the contact joints or the gap between the contact joints or the flat tile A laid on the contact joints and near the upper ends of the cut grooves 4a and 4b. As a result, most of it is discharged into the cut grooves 4a and 4b.
Rainwater after being discharged into a and 4b is smoothly drained forward. In addition, in the joint portion between the adjacent flat tile A in the exposed portion 1 of the flat tile A, the groove width is widened due to the presence of the cut grooves 4a and 4b, and the capillary phenomenon does not occur. Of rainwater is prevented.

(Effects of the Invention) As described above, the present invention provides notches along the side end faces on both sides of the exposed portion of the flat roof tile main body including the exposed portion of the front portion and the overlapping portion of the rear portion. A cut groove is also provided in the middle part from the front end toward the rear, and a plurality of water drainage ridges are provided along the rear side and both sides of the overlapping portion, and both sides of the groove between the water drainage ridges are provided. Since the front end is bent outward and opened at each side end face of the overlapping portion so as to be close to the rear end of the cut groove of the side end face, it is possible to make a large number by laying one flat roof tile with the cut groove. It is possible to give the appearance of showing a small cracking feeling that the roof is made of a number of tiles, and is excellent in workability. Moreover, the rainwater that has infiltrated upward and backward along the surface of the flat roof tiles is dammed up by the water drainage ridges to be waterproofed. The drainage is smoothly removed to the kerf which is the contact joint of the side end surface. That is, the rainwater that has entered the groove has a higher flow velocity in the front-back direction parts on both sides of the groove, but the flow velocity is relaxed at the bent portions at the front ends of the groove to reach the contact joint with the adjacent flat tile. The rainwater is guided down at the abutment joint portion so that the rainwater gently flows through the gap at the abutment joint portion or the gap between the roof tile and the flat roof tile laid thereon, and is collected near the upper end of the notch groove. Most of the water is discharged into the inside of the kerf, and the rainwater after being discharged into the kerf is smoothly drained and removed forward. In addition, due to the presence of the kerf, the groove width is widened in the joint portion between the adjacent flat roof tiles in the exposed portion of the flat roof tile and the capillary phenomenon does not occur, preventing the intrusion of rainwater upward from the same joint portion. To be done.
