Description

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

Ceramic tiles have been around for a long time, but they are quite thick and heavy, so houses built with these tiles had to have thick and strong frames such as columns and beams.

Furthermore, when roof tiles are installed on a roof with a gentle slope, the slope of the upper surface of the tiles becomes even gentler, and rainwater may rise from the overlapping portions due to capillary development and leak.

Furthermore, it is almost impossible to adjust the overlapping margin between tiles, and even if it is possible, it is extremely small and has the disadvantage that gaps are created in the overlapped portions, making it easy for rain to leak.

Additionally, roof tiles made of flat asbestos-cement boards are sometimes used, but although they are much improved in terms of weight, they still have the disadvantage of being prone to leaking when used on roofs with a gentle slope. Ta.

That is, as shown in Fig. 1, the upper surface of the roof tile 2 constructed on the roofing board 1' has a gentler slope, and rainwater permeates into the overlapping part and reaches the rear end 3' of the roof tile 2' below. As a result, the roofing board 1' and fixtures 4' get wet, resulting in rain leakage.

Moreover, since these roof tiles are usually thin, they lack a sense of solidity when viewed from below, and have the disadvantage of being aesthetically inferior.

Furthermore, when fixing these roof tiles to a roof, the roof tiles below the overlapped portion are simply nailed, so they are vulnerable to wind and may be blown away.

This invention solves the above-mentioned drawbacks of the conventional methods.It is easy to install, does not leak even when installed on a roof with a gentle slope, has a solid feel despite being lightweight, and is aesthetically pleasing. The present invention is excellent in that it is possible to adjust the overlapping margin between roof tiles, and provides roof tiles that are resistant to wind blowing.

Next, embodiments of the present invention will be described in detail with reference to the drawings.

A is an example of the roof tile of the present invention, which is integrally molded from a mixed material of asbestos and cement.

The upper surface of the face plate 1 of the roof tile A is made flat and gradually becomes wider from the rear to the front.

Side walls 2, 2 are formed downward from both sides of the face plate 1, and the side walls 2, 2 are wide from the rear to the front.

A folding line 3 is formed inward from the front end of the face plate 1 and the side walls 2, 2C, and a collar edge 4 is formed outward from the rear end of the side wall 2, 2 that extends from the face plate 1.

Thus, when the front part of another roof tile A is superimposed on the rear part of the roof tile A, the ends of the bent edge 3 of one roof tile A are connected to the face plate 1 and the side wall part 2 of the other roof tile A. The outer surface of the rear part of the roof tile A is shaped to follow the outer surface of the roof tile A, and the end of the flange edge 4 of the other roof tile A is shaped to follow the inner surface of the front part of the face plate 1 and side walls 2, 2 of one roof tile A. being done.

A protrusion 5 is formed near the rear end of the upper surface of the face plate 1 of the roof tile A, and a bottomed fixing device insertion hole 6 is provided in the protrusion 5. A protrusion 21 extending in the front-rear direction is provided near the rear end of the outer surface, and a notch 31, 31 is formed in the bent edge 3 to fit with the protrusion 21 of another roof tile A.

B is another example of the roof tile of the present invention, and the face plate 1 of the roof tile B is
A constant middle part 7 having substantially equal width is formed from the middle part between the front and rear parts of the side wall parts 2, 2' to the rear end part.

A protrusion 8 extending in the front-rear direction of the roof tile B is provided near the rear end of the outer surface of the side wall portion 21.21' of the constant width portion 7.

Further, the bent edge 3 of the roof tile B is formed with notches 9, 9 which can fit into the protrusion 8 of another roof tile B.

Next, how the roof tiles A and B are used will be explained.

A base material 11 is laid on the shedding board 10 of the roof, and groove boards 12, 12 are attached at intervals along the vertical direction of the roof.

The groove plates 12, 12 are configured so that the groove portions are opened upward,
For example, it is formed of a metal plate such as a galvanized steel plate.

By adjusting the interval between the groove plates 12, 12, the interval at which the roof tiles A, B are installed can be adjusted.

The groove board 12 is fixed to the roof board 10 by locking the side wall part 13 with hanging tools 14, 14.

The upper end of the rising part of the hanging tool 14 is folded back to form a locking part 15, which is fixed to the roofing board 1o by inserting a fixing member 16 such as a nail.

When the horizontal board 12 is not used with the hanging tools 14, it may be directly attached to the shedding board 1o or the base material 11 using adhesive, or it may be fixed to the shedding board 10 by inserting fixing devices such as nails. You may.

When inserting a fixture into the groove plate 12, operations such as using waterproof gaskets are required for the insertion portion.

Note that it is preferable to attach a synthetic resin foam sheet to the back surface of the groove plate 12 to provide a sound insulation effect.

Next, connect the side wall parts 2, 2 of the roof tile A or B to the adjacent groove plates 1.
Place the roof tile A or B from below the roof so as to straddle the adjacent side wall parts 13. Roof tiles A or B are fixed to the roofing board 10 by inserting fixing tools 16 such as nails.

The front part of another roof tile A or B is overlapped with the rear part of roof tile A or B so that the notch part 31 or 9 fits into the protrusion 21 or 8, and the bent edge of the upper roof tile A or B is Adjust the overlap by sliding the end of 3 vertically on the rear part of the face plate 1 and side walls 2, 2 of the lower roof tile A or B, and fix the protruding part 5 of the upper roof tile A or B. A fixture 16 is inserted through the insertion hole 6 and fixed to the shedding board 10.

Thereafter, in the same manner, roof tiles A or B are installed up to the top of the roof.

By adjusting the horizontal spacing of roof tiles A or B, you can improve the fit of the side walls of the roof, and by adjusting the overlap of roof tiles A or B, you can improve the fit of the lower and upper ends of the roof. By doing so, you can improve the aesthetic appearance and eliminate the need for extra accessories.

In order to firmly fix the roof tile A or B to the shedding board 10, a plurality of protrusions 5 and fixing device insertion holes 6 are provided, and a plurality of fixing devices 16 are attached to each roof tile A or B to fix the shedding board. It may be fixed at 10.

When roof tile A or B is installed on the roof, roof tile A
Alternatively, the top surface of the face plate 1 in B is gentler than the slope of the field board 1°, but rainwater flows from both sides of the face plate 1 to the groove plate 12,
12, and rapidly flows down inside the groove plates 12, 12, which have a slope equal to the slope of the roofing plate 10, and the roof tiles A
Otherwise, it does not enter into the overlapping portion of B.

In addition, even if rainwater may enter the overlapping part of roof tiles A or B during heavy rain or when accompanied by wind, there will be a gap between the face plates 1 and 1 of the upper roof tile and the lower roof tile. Because of this, rainwater does not rise due to capillary action and is returned to the rim 4 of the roof tile A or B further below.

The head of the fixture 16 is exposed on the protrusion 5, but is covered by the face plate 1 and the bent edge 3 of the upper roof tile A or B,
Since it is located at a position protruding from the upper surface of the face plate 1 of roof tile A or B, it does not come into contact with rainwater.

FIGS. 10 and 11 show still another example of the roof tile of the present invention.

A bulging portion 17 that bulges out through a step portion 18 is formed in the front portion of the face plate 1 and side wall portions 2, 2 of the roof tile C shown in FIG. 10 and the roof tile shown in FIG. 11. .

The roof tile is formed relatively long and wide, and to match this, two protrusions 5 are formed near the rear end of the face plate 1, and a fixture insertion hole 6 is formed in the protrusion 5. ing.

Although the shape of the roof tile of the present invention is not limited to the above embodiment, it is necessary that the front part of the face plate 1 and the side wall part 2.2 as a whole be made wider than the rear part.

For roof tiles, it is preferable to use a mixed material of asbestos and cement because it is relatively lightweight, inexpensive, has excellent weather resistance, noncombustibility, and high strength.
Alternatively, it may be formed of a metal plate such as a copper plate or a vinyl chloride-coated steel plate, or a non-combustible material such as glass fiber reinforced concrete.

Further, if nonflammability is not particularly required, it can also be formed from various synthetic resins.

The roof tile of the present invention provides various effects as described below.

(1) In the event of heavy rain or rain accompanied by wind, the front part of the face plate and side wall part is made wider than the rear part to prevent rainwater from entering the overlapping part of the roof tiles. Since gaps are formed between the roof tile and the face plate of the lower roof tile and the side wall, rainwater does not rise due to capillary action, and is further returned by the rim of the roof tile, causing it to spread over the roof tiles and roof tiles. It is possible to prevent the fixing devices that fix the roof board to the roof board from corroding.

(2) When constructing the roof tiles of the present invention, adjust the stacking allowance of the roof tiles in the vertical direction of the roof to improve the fit at the edges of the roof, improve the aesthetic appearance, and improve the appearance of the roof tiles. It also eliminates the need for cutting and adjusting or using extra accessories.

In this case, there may be a slight gap between the folding line of the upper roof tile and the face plate and side wall of the lower roof tile.
Even if rainwater may enter the overlapping part of the upper and lower roof tiles through this gap, the gap is formed between the face plates of the upper and lower roof tiles as described above, so the rainwater will be absorbed by capillary action. The water does not rise due to the rain, and the water is returned by the edges of the roof tiles, so there is no problem in dispersing the rain.

(3) A bent edge is formed inward from the front end of the face plate and the side wall, and the end of the bent edge is shaped to follow the outer surface of the rear part of the face plate and the side wall, so that the lower The folded edges can be seen as the thickness of the roof tile when viewed from above, giving it an extremely solid appearance, but it can also be made into a lightweight roof tile, which reduces the strength required for columns and beams. Since they are relatively small, houses with roof tiles can have lightweight frames such as columns and beams.

(4) Furthermore, in the roof tile of the present invention, since a gap is formed between the face plate and the face plate or roofing plate of the roof tile below, the heat insulation properties of the roof and the sound insulation properties against rain noise can be improved.

(5) A protrusion extending in the front-rear direction is protruded near the rear end of the outer surface of the side wall, and a notch that can fit into the protrusion is formed on the bent edge, so that the front end of the roof tile The bent edge of the roof tile is held in place by the protrusion of the lower roof tile, and even if the roof tile is long and wide, it is strong against the wind and will not be blown away.

(6) In the case of a roof tile in which a constant middle part is provided with approximately equal width from the middle part between the front and rear parts of the face plate and the side wall part to the rear end, the fixed middle part of the lower roof tile Even when adjusting vertically when roof tiles are stacked one on top of the other, the overlapping margin is maintained to maintain a constant gap between the folded edge of the upper roof tile and the face plate and side wall of the lower roof tile. However, the length of the middle part can be adjusted within a certain range.

(7) If a step is formed between the front and rear parts of the face plate and side wall, the front parts of the face plate and side wall are bulged out between the face plate of the upper roof tile and the lower roof tile, and between the side wall parts. It is possible to further increase the distance between the two, thereby further improving the effect of obtaining a feeling of weight (3) above and the sound insulation property (4) above.
