Description

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

Conventionally, with thick cement tiles that have peaks and valleys and a waterproof dam only in the valleys on the front side, when the tile is roofed, the peaks on the front side of the tile and these mountains If the waterproofness between the troughs on the back side of the upper tile that overlaps the roof tile is not sufficient, and rainwater intrudes through the ridges on the front side of the tile to the rear of the dam during strong winds and rain, this dam will cause damage to the dam. There was a problem with rainwater collecting there and leaking through the nail holes and behind the roof tiles to the roof base. Further, in conventional cement tiles, the corner portions are left at right angles or are only beveled, and the tips are thin and sharp, making these portions easy to chip. If the corners that are not hidden by the upper layer tiles or the upper polymer tiles are chipped after roofing, the commercial value will be greatly reduced. Therefore, tiles with chipped parts could not be used, and the yield of tiles was poor.

The present invention eliminates these problems, reduces the overlapping length between the upper and lower tiles, prevents rainwater from penetrating behind the tiles along the peaks, and prevents damage to the corners. The purpose is to provide corrugated roof tiles.

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. However, the first and second
As shown in the figure, ridges 10a and 10b each have a partially cylindrical shape at the edge and midway on one side in the left-right direction (right side in FIG. 1).
However, an elevated portion 10c is formed on the other side.

These first rows (counting from one side) peaks 10
a, plane valley portions 20, 20 are formed between the second row peak portion 10b and the elevated portion 10c, respectively. Elevated area 10c
A plurality of vertically uneven stripes 11 are formed along the front-rear direction. Then, a waterproof weir 21 is installed in the valley 20 at a first distance _S1 from the rear end of the tile (ridge side end when roofing) to the front (eaves side), which is shorter than the overlapping length of the upper layer tile.
A waterproof groove ₁ is provided in the first row ridge portion 10a and the second row ridge portion 10b at a _second distance S2, which is longer than the first distance S1.
2 and 12 are provided.

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.

As shown in FIG. 5, when the tiles A are laid parallel to the ridge of the roof, the first row ridge portion 10a and the elevated portion 10c are laid one above the other, and this overlap forms one complete ridge portion.

As shown in Figures 3 and 4, the back side of the corrugated tile A has a first row of peaks 10a and a second row of peaks 1 on the front side.
0b, the parts corresponding to the elevated part 10c are the first row valley part 30a, the second row valley part 30b, from the left side in FIG. 3, respectively.
A third row of valleys 30c is formed, and the plane valleys 20, 2
a mountain portion 40 whose portion corresponding to 0 has a flat top;
It is said to be 40. Also, on the back side, the mountain part 4
0, 40, first row valley part 30a and second row valley part 3
A waterproof bar 50 is continuously protruded from the front end of 0b, and a hook bar 60 is continuously protruded from the rear end. These waterproof bars 50 and hook bars 60 are on one side (left side in Figure 3).
At the end, it reaches the innermost protrusion 31b, and the other end (right side in FIG. 3) slightly enters the third row trough 30c, where it gently transitions to the curved surface of the trough 30c. Further, the vicinity of the front end of the mountain portion 40 at the rear of the waterproof crosspiece 50 is a flat surface.

A plurality of vertical grooves and grooves 31 that can engage with the vertical grooves and grooves 11 are provided in the first row of valleys 30a. As shown in FIG. 6, the front corner portion of the first row trough portion 30a on the back side of the corrugated tile A (the first row ridge portion 10a from the front side) extends from the end to the first groove 31a. The chamfered portion 7 is cut out in a straight line or curved line within a range where there is no gap.

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. Furthermore, a load-supporting protrusion 34 for preventing tread cracks is provided protrudingly provided at 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 roofing board member by driving a nail into the nail hole 13, but the nail hole 13 is a bottomed hole and can easily be nailed. can be inserted. Additionally, tiles that do not require nailing are left with a bottom. As shown in FIG. 7, when the upper layer tile is superimposed on the lower layer tile, the waterproof crosspiece 50 at the front end is connected to the second row mountain portion 1 of the lower layer tile.
It is located forward of the waterproof groove 12 of 0b. Also,
The front row of water-cutting ridges 32a in the second row of valleys 30b on the back side of the upper tile have their tops aligned with the waterproof grooves 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 water cutting strip 32b in the rear row is located at the nail hole 13.
It is located behind the tile and in front of the rear end of the lower tile. This roofing method allows the overlapping length of the upper and lower tiles to be shortened to the minimum required dimension.

Therefore, at the overlapping part of the upper and lower tiles, rainwater that has entered the rear through the peaks 10 (FIG. 7, 10b) of the lower tiles first enters the waterproof groove 12 and flows into the valleys 20, 20 below on both the left and right sides. Run water. Furthermore, if a large amount of rainwater infiltrates, it reaches the front row drainage ridges 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 rear drain ridge 32b. In this way, rainwater infiltration can be prevented more reliably.

Further, as shown in FIG. 8, the front row of drain grooves 33a in the third row of valleys 30c substantially coincides with the waterproof grooves 12 of the first row of peaks 10a, and is located ahead of the waterproof weir 21, The water cut groove 33b in the rear row substantially coincides with the waterproof weir 21.

Therefore, the rainwater that has entered is removed from the waterproof groove 12 of the lower tile.
Because of the space formed by the front row drain groove 33a of the upper tile, the capillary phenomenon is broken and the water 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 rear drainage grooves 33b, and the rainwater flows down to the trough 20 along the grooves.

On the other hand, when corrugated tiles A are roofed, as shown in FIG.
Since the front end corner portion of the row trough portion 30a), which is a part where tread cracks are likely to occur during tile construction, is made into a chamfered portion 7, tread cracks are less likely to occur. It also prevents tiles from being damaged during transportation and construction.

Furthermore, in this embodiment, since the chamfered portion 7 is formed in a range that does not reach the grooved line 31a of the front row, the first
Even if there are vertical unevenness stripes 31 in the row valley portions 30a, the strength will not be weakened.

FIG. 10 shows another embodiment of the corrugated tile A, in which not only the front corner portion of the first row of peaks 10a on the front side of the tile but also all four corners of the corrugated tile A are chamfered.

As described above, in the present invention, a waterproof groove is provided near the rear end of the peak on the front side of the tile, a waterproof crosspiece is provided at the front end of the back side, a hooking crosspiece is provided at the rear end, and near the front end of the valley on the back side.
Parallel drainage ridges are protruding from the front edge, and the front edge of the back side peak is a flat surface, so even in strong winds and rain, rainwater can enter through the gap between the upper and lower tiles, preventing the roof from leaking. Water does not leak into the base, and there is less overlap between the upper and lower tiles.

Since the ridges are provided in the valleys, the ridges are less likely to be damaged by colliding with other parts during transportation or handling of the tile. Furthermore, since the front corner of the crest located at one end of the front side of the tile is chamfered, damage caused by handling during transportation or construction, and cracking of the front corner after roofing is avoided. This has helped improve the commercial value of roofs and the yield of tiles after roofing.
