Description

[Detailed description of the device] [Industrial applications]

 The present invention relates to a flat roof tile that provides a feeling of small division.

[Prior art]

In the past, many small flat roof tiles were erected to give the roof a small split feeling.

[Problems to be solved by the device]

In the past, a large number of flat tiles had to be laid in a roof, which required time and effort for construction. For this reason, the inventor of the present invention has installed a plurality of roof tiles by forming a plurality of kerfs from the front end of the exposed portion of the roof tile body toward the rear side, and then installed a large number of roof tiles. We are developing flat roof tiles that give a feeling of small division and improve workability. However, although this flat roof tile is nailed and fixed to the roof substrate, there is a problem that rainwater rising in the kerf enters the nailed portion. The present invention was made in order to solve the above-mentioned problems, and the purpose thereof is to make it possible to exhibit a small split feeling that only one piece is laid and that a plurality of pieces are laid. It is to provide a flat roof tile that is highly resistant to rain and is surely rained.

[Means for Solving the Problems]

The flat roof tile of the present invention has two cutting grooves 4a and 4b formed from the front end of the exposed portion 1 of the roof tile body 3 including the front exposed portion 1 and the rear overlapping portion 2 toward the rear, The exposed portion 1 is divided into three exposed portion divided bodies 1a, 1b, 1c, and at the position of the overlapping portion 2 which is deviated outward from the respective center lines a, a of both kerfs 4a, 4b,
A flat roof tile formed by forming nailing holes 5 and 5, respectively, the front end of the exposed portion division body 1a located at one end is retracted rearward to form a short shape, and the remaining two exposed portion division bodies 1b, Aligning the front ends of 1c, it is formed to be longer than the exposed part divided body 1a located at the one side end, and correspondingly, the base end of the cut groove 4b between the two exposed part divided bodies 1b, 1c. By shifting the position to the rear of the base end of the other kerf 4a, and exposing the two exposed portion divided bodies 1b, 1
The kerf 4b between the c is formed longer in the front-rear direction than the other kerf 4a, and the arc-shaped guide portions 6 and 6 having a diameter larger than the groove width dimension of both the kerfs 4a and 4b, respectively. It is provided at the base ends of both the cut grooves 4a and 4b, and the above problem is solved by this configuration. [Operation] With a plurality of cut grooves 4, if one flat plate roof tile A is laid, it is possible to give the appearance of a small split feeling that a large number of roof tiles are laid, and the workability is excellent. Moreover, the nailing hole 5 is provided at a position deviated from the center line a of the cut groove 4 of the overlapping portion 2.
Since the rainwater that rises up through the kerf 4 does not enter the nail driving hole 5, the rain is surely secured. [Example] The roof tile body 3 is an inorganic plate such as a fiber cement plate,
The front part is the exposed part 1 and the rear part is the overlapping part 2. Two cut grooves 4 are formed from the front end of the exposed portion 1 of the roof tile body 3 toward the rear, and the exposed portion 1 is divided into three equal parts by the cut groove 4. The rear end of the kerf 4 is formed in an arc shape to serve as a guide portion 6. The left-side exposed portion divided body 1a is formed shorter than the other divided bodies 1b and 1c, and the cut groove 4a is also formed shorter than that by the cut groove 4b. A reference front end line b crosses the guide portion 6 of the cut groove 4a on the short side, and the front end of the rear tile main body 3 is aligned along the reference front end line b during construction. The corners at the front end of each divided body 1a, 1b, 1c are cut out to form a cutout portion 7 so that each divided body 1a, 1b, 1c has a separate and independent appearance when it is roofed. There is. A nail driving hole 5 is formed behind the cut groove 4 of the overlapping portion 2 and at a position deviated from the center line a of the cut groove 4. Specifically, the width W of the roof tile body 3 is 606 mm, the length L is 445 mm, and the kerfs 4a, 4b
Have lengths l ₁ and l ₂ of 152 mm and 182 mm, respectively, and the deviation hl of the nailing hole 5 from the center line a of the kerf 4 is 50 mm. Draining ridges 8 are formed on the outer peripheral portion of the overlapping portion 2, and alignment marks 9 are formed on the central portions of both side end portions and the rear end portion. During the construction, the flat tile A is nailed and fixed to the roof substrate through the nail holes 5, and then the reference front end line b and the alignment mark 9 are used as marks to superpose the flat tile. The front part 1 of A is piled up and is sequentially laid. In this way, the roof tile A is laid and the exposed portion divided bodies 1a, 1b,
1c can give the appearance that a large number of small tiles are being laid.

[Effect of device]

According to the present invention, two cut grooves are formed from the front end of the exposed part of the roof tile body, which is composed of the exposed part of the front part and the overlapping part of the rear part, to the rear side, and the exposed part is divided into three exposed parts. A flat roof tile formed by splitting into split bodies and forming nailing holes at the positions of the overlapping portions that deviate outward from the respective center lines of both kerfs, and the exposed portion split at one end The front end of the body is retracted rearward to form a short shape, the front ends of the remaining two exposed portion divided bodies are aligned, and the exposed portion divided bodies located at the one side end are formed to be longer forward, and correspondingly , The base end of the kerf between the remaining two exposed part divisions is displaced rearward from the base end of the other kerf, and the kerf between the remaining two exposed part divisions is Longer than the kerf in the front-rear direction, arc-shaped guides with a diameter larger than the width of both kerfs Although it is provided at the base end of the groove, since a plurality of cut grooves are formed from the front end of the exposed part of the roof tile main body, which is composed of the exposed part of the front part and the overlapping part of the rear part, to the rear side. , It is possible to give the appearance that a large number of roof tiles are being laid if one flat tile is laid, and it is possible to give a feeling of small splitting with such simple construction, excellent workability, Moreover, because the nailing hole is formed at a position deviating from the center line of the kerf of the overlapping portion, rainwater rising up the kerf does not enter the nailing hole, and the rain finish is reliable. It will be. Furthermore, as mentioned above, the feeling of splitting of the tiled roof is more strongly emphasized in appearance, but in this case, the base end of the longer kerf of the two kerfs should approach the nailing hole. However, due to the arc-shaped guide portions that are provided at the base ends of the two kerfs and have a diameter larger than the groove width dimension of the kerfs, It prevents the occurrence of cracks between the base end and the nail holes.
