Description

[Detailed explanation of the idea] The present invention relates to improvement of corrugated roof tiles.

Conventional thick cement tiles with peaks and valleys, but with waterproof dams only in the valleys on the front side, when the tile is roofed, the peaks on the front side of the tile overlap these peaks. The waterproofness between the tile and the valley on the back side was not sufficient.

Therefore, if rainwater infiltrates behind the weir through the peaks on the front side of the tiles during strong winds, the presence of the weir will actually prevent the rainwater from flowing downward and collect there. There was a problem with water leaking from the nail holes and even from the rear edge of the tiles (ridge side edge when roofing was done) to the roof base.

The object of the present invention is to solve the above-mentioned problems and provide a tile that can prevent as much as possible rainwater from penetrating into the rear part of the tile along the crest of the tile between the roof tile and the upper tile.

An embodiment of the present invention will be described below based on the drawings.

As shown in FIGS. 1 to 4, the corrugated tile A of the present invention has front and rear edges along the roof ridge direction and left and right edges along the roof inclination direction, and is rectangular in plan view. As shown in FIGS. 1 and 2, the front surface has partially cylindrical peaks 10a and 10b at the edge and midway on one side in the left-right direction (right side in FIG. 1), respectively, and a raised portion 10c on the other side. It is formed. Planar valley portions 20, 20 are formed between the first row (counting from one side) peak portion 10a, second row peak portion 10b, and elevated portion 10c, respectively. A plurality of vertically uneven stripes 11 are formed on the elevated portion 10c along the front-rear direction. Then, a waterproof weir 21 is installed in the valley 20 at the trough 20 at a first distance _S2 shorter than the overlapping length of the upper layer tiles from the rear edge of the tile (ridge side edge when roofing) to the front (eaves side), and the first distance S _Second distance S longer than 1 First row mountain portion 10a, second row mountain portion 10b at ₂ positions
are provided with waterproof grooves 12, 12, respectively.

A nail hole 13 with a bottom is provided behind the waterproof groove 12 at the top of the second row mountain portion 10b. The nail hole 13 is formed so that a nail can easily pass through it. In addition, in the corrugated tile A, the front corner portion of the first row of mountain portions 10a is cut in a straight line or curved shape within a range that does not reach the first grooved line 31a from the end of the back surface described later, and the chamfered portion 7 It is said that

When the corrugated tile A is arranged parallel to the ridge of a roof, the first row of peaks 10a and the elevated part 10c are laid one on top of the other, and as a result of this superposition, they form one complete peak.

Therefore, a plurality of longitudinally uneven stripes 31 that can engage with the longitudinally uneven stripes 11 are provided on the back side of the first row of mountain portions 10a. The back side of tile A is as shown in Figures 3 and 4.
Portions corresponding to the first row mountain portion 10a, the second row mountain portion 10b, and the elevated portion 10c on the front side are respectively,
From the left in Fig. 3, the first row valley portion 30a, the second row valley portion 3
0b, the third row valley part 30c, and the plane valley part 2
The portions corresponding to 0 and 20 are peak portions 40 and 40 having flat tops. Further, on the back side, waterproof bars 50 are continuously protruded from the front ends of the peaks 40, 40, the first row troughs 30a, and the second row troughs 30b, and a hook bar 60 is continuously protruded from the rear ends. There is. these,
The waterproofing crosspiece 50 and the hooking crosspiece 60 reach the innermost concavo-convex strip at one end (the left side in FIG. 3), and the other end (the right side in FIG. 3) reaches the third row trough 30c a little. It smoothly transitions to the curved surface of the third row valley portion 30c. At the rear of the waterproof ladder 50, the vicinity of the front end of the mountain portion is a flat surface.

The second row trough portion 30b on the back side and the first
Near the front end of the row trough portion 30a, two rows of draining ridges 32 are protrudingly provided, parallel to the front edge of the tile and parallel to each other along the front-rear direction. In addition, two rows of drain grooves 33 are provided in the third row valley portion 30c in parallel with the front edge of the roof tile in the front-rear direction. Note that a load-supporting protrusion 34 for preventing tread cracks is provided protrudingly in the middle of the second row trough portion 30b in the front-rear direction on the back side. Note that 8 in the third figure is a thin wall portion for reducing the weight of the tile itself, and 41 is a name attachment portion.

Next, the mode of use will be explained.

When the corrugated tile A is placed on a roof with the front side facing upward, the lower layer tile is fixed to the roof board member by driving a nail into the nail hole 13, but the nail hole 13 is a hole with a bottom. Therefore, nailing is easy. Also,
Tiles that do not require nailing are left with a bottom. As shown in FIG.
is located forward of the waterproof groove 12 of the second row mountain portion 10b of the lower tile. Also, the second layer on the back side of the upper tile
The first from the front of the draining ridge 32 in the row valley portion 30b
The top of the third one 32a is connected to the waterproof groove 12.
It is located at the rear and approximately at the same position as the front end surface of the waterproof weir 21, or at the front. Also,
The top of the second draining ridge 32b is located behind the nail hole 13 and in front of the rear end of the lower tile. By this method of roofing, the overlapping length of the upper and lower tiles can be shortened to the minimum required dimension.

Therefore, at the overlapping portion of the upper and lower tiles, rainwater that has entered through the peaks 10 of the lower tiles first enters the waterproof groove 12 and flows out to the lower valleys 20, 20 on both the left and right sides. Furthermore, if a large amount of rainwater infiltrates, it reaches the first drainage protrusion 32a of the upper tile, and from there, infiltration to the rear is prevented and flows out to the left and right valleys 20, 20. In the unlikely event that rainwater infiltrates further to the rear, it is blocked by the second drainage protrusion 32b. In this way, rainwater infiltration can be prevented more reliably.

In addition, as shown in FIGS. 6 and 7, the third row valley portion 30
The first one 33a from the front of the drain groove 33 of c.
substantially coincides with the waterproof groove 12 of the first row mountain portion 10a,
The second ditch groove 33b is located in front of the waterproof weir 21 and substantially coincides with the waterproof weir 21.

Therefore, the infiltrated rainwater is broken by capillary action due to the space formed by the waterproof groove 12 of the lower tile and the first drainage groove 33a of the upper tile, and flows down through the space to reach the trough 20. Even if a large amount of rainwater enters, the capillary phenomenon is broken by the second drainage grooves 33b, and the rainwater flows down to the valley portion 20 along the grooves.

Corners of roof tiles are easily damaged during construction, and especially if the dripping part on the front side is damaged, it will be unsightly, but since this partial chamfered part 7 has been formed in advance, tread cracks and contact cracks will not occur. Therefore, the roof is in good condition and the appearance is good.

As described above, the present invention has a waterproof groove near the rear end of the peak on the front side of the tile, a waterproof crosspiece at the front end of the back side, a hooking crosspiece at the rear end, and a waterproof groove near the front end of the valley on the back side. Since the front edge of the roof tiles has parallel drainage ridges that protrude, even during strong winds and rain, rainwater will not enter through the gap between the upper and lower tiles and leak into the roof base.
The overlapping length of the upper and lower tiles can now be shortened. Furthermore, since the draining ridges are provided in the valleys, the tile is less likely to be damaged by collisions with the ridges during transportation or handling.
