Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a roof tile generally referred to as a moniel roof tile.
In particular, the present invention relates to a roof tile that has an improved structure at a connecting portion with a laterally adjacent roof tile.

[Conventional technology]

With reference to FIG. 2, FIG. 3, and FIG. 4, the connection structure of a conventional Moniel tile with a laterally adjacent tile will be explained.

In conventional roof tiles, a large number of roof tiles were installed, as shown in Figure 2. That is, the tile 1 is connected to the tile 2 adjacent to the lateral side, and the tiles 1 and 2 are installed so that their front edges are placed over the rear edges of the tiles 3 and 4. Further, although not particularly illustrated, tiles are sequentially installed behind the tiles 1.2.

The structure of the connection part with the side neighbor provided on the tiles 1 to 4 above is as follows:
This will be explained using tile 4 as a representative. As is clear from Figure 2,
A first connecting portion 5 is provided along the first side edge 4a of the roof tile 4. The first connecting portion 5 forms a recess 5a extending from the front edge 4c to the rear edge inside the first side edge 4a, thereby creating a space between the recess 5a and the first side edge 4a in the front-rear direction. It is constructed by forming a convex portion 5b that extends to.

On the other hand, a second connecting portion 6 is formed on the second side edge 4b side. This second connecting portion 6 is connected to the first connecting portion 5.
a concave portion 6a into which the convex portion 5b fits, and a convex portion 6b which is provided between the concave portion 6a and the second side edge 4b and fits into the concave portion 5a of the first connecting portion 5. It is constituted by forming.

A connection structure between laterally adjacent tiles using the first connecting part 5 and the second connecting part 6 will be described with reference to FIG. 3, which is a cross-sectional view taken along the line ■-■ in FIG. 2. As is clear from FIG. 3, in the first connecting portion 5 of the tile 1, the first connecting portion 5
The convex part 6 of the second connecting part 6 of the tile 2 adjacent to the side is inserted into the concave part 5a of
B or bushes are nestled together. Similarly, the convex portion 5b of the first connecting portion 5 fits into the recess 6a of the second connecting portion 6 of the tile 2 adjacent to the side. Each concave portion 5a, 6a and convex portion 6a.

Since the tiles 6b are all shaped to extend in the front and back direction, by achieving the connection state shown in FIG. 3, the roof tiles 1.2 are reliably connected so as not to come off laterally. Ru.

By the way, when installing tiles on a roof, it is not enough to simply connect them to the adjacent tiles on the side using the above connection structure, but also to fix the tiles to the field with screws or nails and securely install the tiles on the roof. is normal. For this purpose, as shown in FIG. 2, a thin portion 5C is formed at a position a predetermined distance from the front edge of the convex portion 5b of the first connecting portion 5. Using this method, nails 7 were driven into the field (not shown) as shown in FIG. 3, and tiles 1 were fixed in place.

By the way, the reason why the part to be nailed, that is, the thin wall part 5c, is configured to have a certain length as shown in the figure is as follows.

In other words, as shown in Fig. 4 (a) and (b), when tiles with a phase number of 1.3 are raised in the direction of the eaves, in the direction of the eaves,
In other words, it is necessary to adjust the overlapping radius of the front and rear tiles. Therefore, the thin wall portion 5c is configured to have a predetermined length as shown in the figure in order to change the position where the nail 7 is driven in accordance with the change in the overlapping mark of the front and back tiles 1.3. There is.

Moreover, as is clear from FIG. 3, the head 7a of the nail 70 is
Since it protrudes upward from the upper surface of the thin part 5c,
As shown in FIG. 2, the thin portion 5c is not only thinned, but also formed such that its upper surface is located below the upper surface of the convex portion 5b.

[Problem to be solved by the invention]

The above-mentioned conventional method 1. In the connection structure using the second connection parts 5 and 6, the thickness of the thin wall part 5c for nailing is not only set to a thickness that facilitates nail driving, but also the thickness of the nail 7
In order to prevent the head 7a from hitting the inner wall of the recess 6a of the second connecting part 6, it is formed very thin. As a result, cracks and chips tend to occur frequently in the first connecting portion 5 during handling during manufacturing and construction of tiles.

Further, when the roofing is adjusted in the direction of the eaves, needle holes must be formed in the thin wall portion 5C each time, resulting in poor workability.

Therefore, an object of the present invention is to provide a roof tile that has a structure in which the strength of the connection part for connection with the lateral neighbor is increased, and the work of roof adjustment in the direction of the eaves can be easily performed. be.

[Means to solve the problem]

In the tile of the present invention, the first tile is connected to the tile next to the lateral side. The second connecting portion is connected to the first connecting portion. It is provided along the second side edge. The first connecting portion includes, on the surface side of the tile, a recess that extends from the front edge of the tile to the rear edge inside the first side edge, and a portion between the recess and the first side edge that extends from the front fa edge. It has a convex portion extending to the rear i-edge. The second connecting portion is located between a recess that extends from the front edge of the tile to the rear edge of the tile inside the second side edge and a second side edge of the recess on the back side of the tile. and a convex portion extending from the front end edge to the rear end edge.

The recess and convex portion of the first connecting portion can be fitted into the convex portion and the concave portion of the second connecting portion of the laterally adjacent roof tile, respectively.

A feature of the tile of the present invention is that needle holes are formed in the convex part of the first connecting part at a plurality of positions separated by a predetermined distance from the front edge, and on the other hand, the convex part of the first connecting part is connected to the adjacent tile on the side. In the state, the first
A plurality of storage holes capable of storing nail heads are formed in the recessed portion of the second connecting portion of the tile adjacent to the side that covers the needle hole of the tile corresponding to the needle hole. It's in being.

[Effect]

In the tile of the present invention, the concave portion and the convex portion of the first connecting portion are connected by fitting into the convex portion and the concave portion of the second connecting portion of the laterally adjacent tile, respectively. Then, in order to fix the tile to the field or the like, the tile is fixed to the field or the like by driving a nail into one or more of the plurality of needle holes provided in the convex part of the first connecting part. In this case, the head of the nail protrudes above the needle hole, but the head of the nail is accommodated in the storage hole provided in the recess of the second connection part of the lateral adjacent tile.

Therefore, since the thickness of the nail head is absorbed on the second connecting part side, and because the needle hole is formed in advance, the thickness of the convex part of the first connecting part can be reduced as compared to the conventional example. There is no need to make parts very thin.

Further, since the needle holes are formed in advance in the convex portion of the first connecting portion, there is no need to form needle holes during construction.

〔Effect of the invention〕

Therefore, according to the present invention, either the thickness of the head of the nail for fixing to the field or the like at the joint with the adjacent tile on the side is absorbed by the storage hole on the side of the second joint. Therefore, it is not necessary to make the thickness of the nailing portion of the first connecting portion very thin as in the conventional example.

Therefore, the strength of the convex part of the first connecting part into which the nail is driven is effectively increased, and accidents such as cracking or chipping of the tile during handling during manufacture or construction of the tile are effectively prevented. .

Additionally, since needle holes are pre-formed in the area where the nails will be driven, construction workability is also improved. In addition, when nailing, the impact force applied to the part where the nail is driven, that is, the convex part of the first connecting part, is significantly reduced compared to the conventional case, so there is no possibility of damage to the connecting part during nailing. Accidents are also reduced.

[Explanation of Examples]

Hereinafter, a roof tile according to an embodiment of the present invention will be described with reference to the drawings.

Figures 1(a) and (b) are perspective views of the tile of this embodiment shown in different directions, viewed from the front side, and Figure 1(c) is a portion viewed from the back side. FIG. 3 is a cutaway perspective view.

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

The first connecting portion 12 forms a recess 12a extending from the front edge 11c to the rear edge 11d of the tile 11 inside the first side edge 11a, and between the recess 12a and the first side edge 11a. It is constructed by forming a convex portion 12b on. Note that, as is clear from FIG. 1(a), the convex portion 12b
The upper surface of the roof tile 11 is lower than the upper surface of the main body portion of the roof tile 11.

This is because it overlaps with the first connecting portion 13, which will be described later, to form a connecting structure.

On the other hand, the second connecting portion 1 provided on the second side edge 11b side
3 similarly has a concave portion 13a and a convex portion 13b. The concave portion 13a is formed inside the second side edge 11b from the front edge 11c of the tile 11 to the rear edge lid, and the convex portion 13b is formed from the front edge 11c of the tile 11 to the rear edge lid.
c to the rear end edge lid.

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

The feature of the tile 11 of this embodiment is that the convex portion 1 of the first connecting portion 12
2b has a plurality of screw holes 12c to 12e formed therein, and the recess 13a of the second connecting portion 13 has the needle hole 12 formed therein.
Storage holes 13c to 13e for storing nail heads are formed corresponding to holes c to 12e.

The needle holes 12c to 12e are the front end! The needle holes 12c to 1 are formed at a plurality of positions spaced apart from the llc by a predetermined distance.
2e is provided, so in the tile 11 of this embodiment, the roofing is adjusted in the needle direction and the nails are driven.

In this case, it is possible to omit the work of forming a needle hole.

In addition, the storage holes 13c to 13e provided in the recess 13a of the second connecting portion 13 are formed in a size that can accommodate the head of a nail, so the head of a nail that has been driven is stored inside. and thereby function to absorb the thickness of the nail head. This will be explained with reference to FIGS. 5 and 6.

FIG. 5 is a perspective view showing a state in which the tiles 11 of this embodiment are installed, and FIG. 6 is a sectional view taken along the line VI-VI in FIG. 5. As is clear from FIG. 6, the roof tile 11 is fixed to a field (not shown) by driving nails 14 into the convex portion 12b of the first connecting portion 12 in the roofing state. In this case, the head 14a of the nail 14 is housed in the housing hole 13c formed in the recess 13a of the second connecting part 13 of the tile 21 adjacent to the side, as shown in the figure. 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.
In order to absorb the thickness of a, the part of the first connecting part 5 where nailing is performed is made into a very thin part 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 tile 11 of this embodiment, the thickness of the head 14a of the nail 14 is absorbed by the storage hole 13C as described above, and the needle holes 12c to 12e are formed. Therefore, on the convex portion 12b of the first connecting portion 12,
There is no need to provide particularly thin parts. Therefore, the strength of the first connecting portion 120 can be effectively increased.

Note that the above-mentioned storage hole 13c is provided on the second connecting portion 13 side.
~13e are provided, but such storage holes 13c~1
3e is nothing more than a plurality of them 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, in order to slightly reduce the thickness of the portion where the needle holes 12c to 12e are formed, recessed part 1
2f is formed. This recessed portion 12f is located at the needle hole 12c.
This is merely provided to facilitate the machining of steps 12e to 12e, and therefore, it may be omitted if the needle hole machining can be performed smoothly. Also, even if the recess 1
Even if 2f is formed as shown, the recess 1
Since 2f is formed relatively shallowly, the convex portion 12
The strength of b does not decrease much.

The size of the storage hole 13 cm 13e described above may be any size that allows the head of the nail to be inserted into it.
Therefore, although it varies depending on the size of the nail used, the storage hole is preferably formed with a diameter of 5L or more and a depth of 1 or more.

Further, in the embodiment shown in FIG. 1, the explanation was given using a flat tile with a flat tile main body, but the present invention can also be applied to a wavy tile with a crest and a trough. can. That is, the present invention provides the first and second side edges of the roof tile.
．． Since the structure of the second connecting part is unique,
The shape and structure of other parts of the tile are arbitrary.
