Description

Description: TECHNICAL FIELD The present invention relates to a roof tile generally referred to as a moniel roof tile, and more particularly to a roof tile having an improved structure of a connecting portion between adjacent roof tiles.

[Conventional technology]

With reference to FIG. 2, FIG. 3 and FIG. 4, the connecting structure of the conventional roof tile with the roof tile adjacent to the side will be described.

In the conventional roof tile, as shown in FIG. 2, many roof tiles were laid. That is, the roof tile 1 is connected to the roof tile 2 adjacent to the side, and the roof tiles 1 and 2 are roofed so that the front end edges thereof cover the rear end edges of the roof tiles 3 and 4. Further, although not particularly shown, tiles 1 and 2 are also sequentially tiled behind the tiles.

The structure of the connecting portion provided on the roof tiles 1 to 4 and adjacent to the lateral side will be described on behalf of the roof tile 4. As is apparent from FIG. 2, the first connecting portion 5 is provided along the first side edge 4a of the roof tile 4. The first connecting portion 5 has a concave portion 5a formed inside the first side edge 4a and extending from the front end edge 4c to the rear end edge, whereby the front-back direction is provided between the concave portion 5a and the first side edge 4a. It is configured by forming a convex portion 5b extending to the.

On the other hand, the second connecting portion 6 is formed on the side of the second side edge 4b. The second connecting portion 6 is the first connecting portion 5 described above.
A concave portion 6a with which the convex portion 5b is fitted, a concave portion 6a and a second side edge 4b
And a convex portion 6b which is provided between the concave portion 5a of the first connecting portion 5 and the concave portion 5a of the first connecting portion 5.

A connecting structure using the first connecting portion 5 and the second connecting portion 6 to a roof tile adjacent to the side will be described with reference to FIG. 3, which is a sectional view taken along line III-III of FIG. . As is clear from FIG. 3, in the first connecting portion 5 of the roof tile 1, the convex portion of the second connecting portion 6 of the roof tile 2 laterally adjacent to the concave portion 5a of the first connecting portion 5 is formed.
6b fit together. Similarly, the convex portion of the first connecting portion 5
5b is fitted in the recess 6a of the second connecting portion 6 of the roof tile 2 adjacent to the side. Since each of the concave portions 5a, 6a and the convex portions 6a, 6b has a shape extending in the front-rear direction, by realizing the connected state shown in FIG. It is firmly connected so that it does not come off.

By the way, when roofing the roof tiles, not only simply connecting the roof tiles on the lateral side using the above-mentioned connection structure, but also fixing the roof tiles to the field with screws and nails, and securely roofing the roof tiles. Is normal. Therefore, as shown in FIG. 2, in the convex portion 5b of the first connecting portion 5, a thin portion 5c is formed at a position separated from the front edge by a predetermined distance. Utilizing this, the nail 7 was driven into the field (not shown) as shown in FIG. 3, and the roof tile 1 was fixed.

By the way, the reason why the nailing portion, that is, the thin portion 5c has a certain length as shown in the figure is as follows.

That is, as shown in FIGS. 4 (a) and (b), when a plurality of roof tiles 1 and 3 are being raised toward the eaves,
That is, it is necessary to adjust the overlapping width of the front and rear roof tiles. Therefore, depending on the variation of the overlapping margin of the roof tiles 1 and 3 before and after this,
Since the position at which the nail 7 is hit varies, the thin portion 5c has a predetermined length as shown.

Further, as is clear from FIG. 3, the head 7a of the nail 7 is
Since the thin portion 5c projects upward from the upper surface of the thin portion 5c, as shown in FIG. 2, the thin portion 5c is not simply thinned, but its upper surface is higher than the upper surface of the convex portion 5b. Is also formed to be located below.

[Problems to be Solved by the Invention]

In the above-described conventional connecting structure of the first and second connecting portions 5 and 6, the thickness of the thin portion 5c for nailing is not only the thickness for facilitating nailing, but also the nailing. The head 7a of 7 was formed to be very thin so as not to hit the inner wall of the recess 6a of the second connecting portion 6. as a result,
When manufacturing the roof tile or handling it during construction, the first connecting portion 5 was likely to be cracked or chipped frequently.

Further, when the roofing is adjusted in the eaves direction, it is necessary to form a nail hole in the thin portion 5c each time, which causes a problem of poor workability.

Therefore, an object of the present invention is to provide a roof tile having a structure in which the strength of a connecting portion for connecting with a side adjacent to the side is enhanced and a work for adjusting a roofing in the eaves direction can be easily performed. is there.

[Means for solving the problem]

In the roof tile of the present invention, the first and second connecting portions for connecting to the roof tiles laterally adjacent to each other are provided along the first and second side edges. The first connecting portion is, on the front surface side of the roof tile, a recess extending inside from the first side edge from the front end edge to the rear end edge of the roof tile, and between the recess and the first side edge from the front end edge to the rear side. And a protrusion extending to the edge. Further, the second connecting portion is on the back surface side of the roof tile, and is located between the second side edge inside the second side edge and extending from the front edge to the rear edge of the roof tile and the second side edge with the recess. And a convex portion extending from the front end edge to the rear end edge. The concave portion and the convex portion of the first connecting portion are configured so that they can be fitted with the convex portion and the concave portion of the second connecting portion of the tile adjacent to the side, respectively.

The feature of the roof tile of the present invention is that nail holes are formed at a plurality of positions at a predetermined distance from the front end edge in the convex portion of the first connecting portion, and on the other hand, it is connected to the roof tile adjacent to the side. In this state, a plurality of heads of nails can be housed in portions corresponding to the nail holes in the recesses of the second connecting portions of the tiles laterally adjacent to the nail holes of the first tile. The storage hole is formed.

[Action]

In the roof tile of the present invention, the concave portion and the convex portion of the first coupling portion are coupled by being fitted into the convex portion and the concave portion of the second coupling portion of the laterally adjacent roof tile, respectively. Then, in order to fix the roof tile to the field or the like, the roof tile is fixed to the field or the like by driving a nail into one or more nail holes of the plurality of nail holes provided in the convex portion of the first connecting portion. In this case, the head of the nail is projected above the nail hole, but the head of the nail is housed in the storage hole provided in the recess of the second connecting portion of the tile adjacent to the side.

Therefore, the thickness of the nail head portion is absorbed on the side of the second connecting portion, and the nail hole is formed in advance.
Unlike the conventional example, it is not necessary to make the thickness of the convex portion of the connecting portion extremely thin.

Further, since the nail hole is formed in the convex portion of the first connecting portion in advance, it is not necessary to form the nail hole at the time of construction.

[Effects of the Invention] Therefore, according to the present invention, the thickness of the head portion of the nail for fixing to the field or the like is the second at the connection portion with the tile adjacent to the side.
Since it will be absorbed in the storage hole on the side of the connecting part of
Unlike the conventional example, it is not necessary to make the thickness of the nail striking portion of the connecting portion very thin. Therefore, the strength of the convex portion of the first connecting portion to which the nail is struck is effectively increased, and an accident in which the roof tile is cracked or chipped is effectively prevented during handling of the roof tile during manufacturing or construction. .

Further, since the nail hole is formed in advance in the portion where the nailing is performed, workability is also improved. In addition, the impact force applied to the nailed portion, that is, the convex portion of the first connecting portion at the time of nailing is significantly reduced as compared with the case of the conventional example, so that the connecting portion is damaged at the time of nailing. Accidents are also reduced.

[Explanation of Example]

A roof tile according to an embodiment of the present invention will be described below with reference to the drawings.

FIGS. 1 (a) and 1 (b) are perspective views of the roof tile of this embodiment shown in different directions, as viewed from the front side.
FIG. 1C is a partially cutaway perspective view seen from the back surface side.

In the roof tile 11 of the present embodiment, the first connecting portion 12 is provided on the first side edge 11a side and the second connecting portion 13 is provided along the second side edge 11b.

The first connecting portion 12 forms a recess 12a extending from the front end edge 11c to the rear end edge 11d of the roof tile 11 inside the first side edge 11a, and between the recess 12a and the first side edge 11a. It is configured by forming a convex portion 12b on the. As is apparent from FIG. 1A, the upper surface of the convex portion 12b is lower than the upper surface of the main body portion of the roof tile 11. This is because they overlap with a first connecting portion 13 described later to form a connecting structure.

On the other hand, the second connecting portion 13 provided on the second side edge 11b side
Similarly has a concave portion 13a and a convex portion 13b. Recess 13a
Is a front end edge 1 of the roof tile 11 inside the second side edge 11b.
It is formed so as to extend from 1c to the rear edge 11d, and similarly, the convex portion 13b is formed so as to extend from the front edge 11c to the rear edge 11d of the roof tile 11.

Up to this point, the structure is similar to that of the conventional roof tile described with reference to FIGS. 2 and 3.

The feature of the roof tile 11 of this embodiment is that the protrusion 12b of the first connecting portion 12 is
A plurality of screw holes 12c to 12e are formed in the concave portion 13a of the second connecting portion 13 and corresponding to the nail holes 12c to 12e. 13c to 13e are formed.

The nail holes 12c to 12e are formed at a plurality of positions separated from the front end edge 11c by a predetermined distance, and since the nail holes 12c to 12e are provided, the roof tile 11 of this embodiment is roofed in the eaves direction. It is possible to omit the work of forming a nail hole when adjusting and striking a nail.

Further, the storage hole 1 provided in the recess 13a of the second connecting portion 13
Since 3c to 13e are formed to have a size capable of accommodating the nail head, the nail head that has been struck can be accommodated inside, thereby functioning to absorb the thickness of the nail head. . This will be described with reference to FIGS. 5 and 6.

FIG. 5 is a perspective view showing a state in which the roof tile 11 of the present embodiment is installed, and FIG. 6 is a sectional view taken along line VI-VI in FIG. As is clear from FIG. 6, the roof tile 11 is
The nail 14 is struck on the convex portion 12b of the first connecting portion 12 and fixed to the field (not shown). In this case, the head 14a of the nail 14 is, as shown in the figure, the recess 13a of the second connecting portion 13 of the roof tile 21 adjacent to the side.
It is stored in the storage hole 13c formed in. That is,
The thickness of the head 14a of the nail 14 is absorbed by the storage hole 13c.

In the conventional roof tile connection structure shown in FIG. 3, the head of the nail 7 is
In order to absorb the thickness of 7a, the portion where the nailing of the first connecting portion 5 is performed is a very thin thin portion 5c. Therefore, the strength of the first connecting portion 5 becomes very weak, and damage or the like tends to occur.

On the other hand, in the roof tile 11 of the present embodiment, as described above, the thickness of the head portion 14a of the nail 14 is absorbed by the storage hole 13c, and the nail holes 12c to 12e are formed. Therefore, it is not necessary to particularly provide a thin portion on the convex portion 12b of the first connecting portion 12. Therefore, the strength of the first connecting portion 12 can be effectively increased.

In addition, the storage holes 13c to 1c described above are provided on the second connecting portion 13 side.
Although 3e is provided, such a plurality of storage holes 13c to 13e are merely provided at appropriate intervals.
Therefore, the strength of the second connecting portion 13 is not significantly reduced by providing the storage holes 13c to 13e.

In addition, as shown in FIGS. 1 (a), (c) and FIG. 3, in this embodiment, the back surface side is formed in order to slightly reduce the wall thickness of the portion where the nail holes 12c to 12e are formed. A recess 12f is formed in the. The recess 12f is merely provided to facilitate the processing of the nail holes 12c to 12e, and therefore,
It may be omitted if the processing of the nail holes can be performed smoothly. Even if the recess 12f is formed as shown in the figure, the strength of the protrusion 12b does not decrease so much because the recess 12f is formed relatively shallow.

It should be noted that the size of the above-described storage holes 13c to 13e may be any size that allows the head of the nail to be used to enter, and therefore varies depending on the size of the nail to be used, but preferably a diameter of 5 mm or more, a depth. A storage hole with a size of 1 mm or more is formed.

Further, in the embodiment shown in FIG. 1, the roof tile main body has been described as an example of a flat roof tile, but the present invention can also be applied to a corrugated roof tile having a peak portion and a valley portion. it can. That is, the present invention is directed to the first and second side edges of the roof tile.
Since the structure of the second connecting portion has a characteristic, the shape and structure of the other portion of the roof tile are arbitrary.
