Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention is provided with a locking structure between roof tiles of the same horizontal tile and a locking structure between diagonal roof tiles and stable fixing of a single roof tile.
Regarding roof tiles that do not slip or float even in strong winds

(Prior Art) The conventional thick flat roof tile has a roof tile W shown in FIGS. 10 (1) and 10 (2).
As described above, a nail hole 10 for nailing on the hip R side is formed, and a part of the hole is also provided on the top of the cross section S to some extent. Insert 2 into head drop 2Ts
There was no locking mechanism near Tu, and no positive measures were taken in the shape and structure of the roof tiles to prevent the roof tiles from shifting and floating due to the combination of roof tiles.

Only by fixing the nail hole 10 on the bottom R side, the roof tile T
There is no effect against floating and deviation from the side, and nailing at the top of the cross section S may cause rainwater intrusion due to corrosion of the nail material and deterioration of the seal material, and is also unfavorable in appearance.

There is also a method in which a stopper is directly attached to the side edge of the inserting portion U to fix it to the ground plate, but this method causes the retaining metal to attract and leak rainwater invading the inserting portion U. It was easy.

Some of them have a claw-shaped projection on the back surface near the hanging portion T so that the projection can be caught by the projecting portion on the side of the buttocks, but this does not have a lateral slip prevention effect at all. is there.

(Problems to be Solved by the Invention) The present invention provides a safe and effective locking function by providing a mutual locking combination mechanism between the roof tiles in the same row and the roof tiles in the upper and lower rows in the shape and structure of the roof tiles themselves. In this way, the roof tiles do not slip or float even when the wind is strong, rainwater does not leak, and the construction is not hindered.

(Means for Solving the Problem) A first configuration of the invention is that a locking projection 8 is formed on the inner side of the lower end Ts of the roof tile and the insertion drooping part is formed by removing a part of the lower end. As the insertion drooping part Tu, the insertion drooping part Tu of the insertion side roof tile is inserted and mounted on the locking projection 8 of the adjacent insertion target tile when the tiles are lined up and locked with each other, Further, the single roof tile itself is a wind-resistant flat roof tile that can fix the outer side of the water return wall 9 on the insertion portion U side to the base plate N via a stopper 12.

In the second configuration of the invention, the recessed portion 1 is formed in the bottom portion R of the roof tile,
Locking projections 2a, b, c are projected on the insertion portion U side near the insertion drooping part Tu, and when the roof is piled up, the locking projections 2a of the stacking upper row tiles Part of b, c fits in, and the small protrusions 3a, b, c provided on that part are infiltrated and locked, and the locking protrusions 2a, b, c themselves also via the stopper 11, or directly. It is a wind resistant flat tile that can be fixed to the base plate N with nails.

In addition, by combining the above-mentioned main constituent technologies, the functions of preventing lateral slippage / floating during strong winds can be further synergistically achieved.
It can be expressed to a higher degree.

(Operation) (1) When the roof tiles of the inventions set forth in claims 1 and 2 are roofed in the same row and row direction, they are adjacent to each other on the locking projections on the inner side of the lower end of the pier drop portion. The insertion hanging portions of the roof tiles are fitted into each other, and the vertical floating and movement of the roof tiles are locked to each other, and all the roof tiles in the row direction are connected.

Further, when the concave portion of the insertion side edge of the single roof tile is fixed to the base plate by the fastener, the single roof tile itself is prevented from floating from the hanging portion side and the lateral shift is prevented.

(2) When the roof tiles of the invention described in claims 3 to 5 are put together, in addition to the action of the preceding paragraph, in addition to the effect of the preceding paragraph, the concave portion of the roof tile on the lower side is inserted into the insertion portion side of the roof tile on the upper side. The locking projection fits in, preventing floating between the upper and lower roof tiles and horizontal displacement,
The floating from the side of the drip is also suppressed.

Also, by fixing the locking protrusion on the insertion side to the base plate,
The floating of the single roof itself from the hanging portion side and the lateral slip prevention are performed.

Due to the above-described connecting and locking action in the horizontal direction of the same stage and the restraining locking action between the upper and lower stages, the roof tiles on the entire roof surface are chained to synergistically enhance the function.

(Embodiment) The present invention will be described below with reference to the drawings of the embodiments.

In the first embodiment, like the roof tile X shown in FIGS. 1 (1) and (2), the locking projection 8 is formed inside the lower end of the pier drop portion Ts, and the insertion droop portion Tu is the same as that of the conventional roof tile. As a short shape with the lower end of the insertion droop 2Tu removed, this roof tile X
When the roof tiles are lined up, as shown in FIGS. 2 (1) and 2 (2), the insertion hanging portion of the insertion-side tile X ₁ is placed on the locking projection 8 of the tile X on the insertion-side between the tiles adjacent to each other. The Tu is inserted and placed.

In the second embodiment, like the roof tile 2X shown in FIGS. 3 (1) and (2), the protrusion of the water bar 9 on the edge of the insertion portion U side is partially moved inward to avoid overflow of running water. In this method, a recess 7 is formed on the outer side of the recess 7, and a fastener 12 is hung on the recess 7 to fix the recess 7 to the base plate. Although the structure of the first embodiment is not shown in the drawing here, the structure of the first embodiment is not shown.
The prevention of roof tile floating is further enhanced by adding a fixing structure on the insertion portion U side.

It should be noted that it is also easy to conceive from the above that a nail hole is provided in the recess 7 and the nail is directly fixed and fixed to the roof base plate with a nail.

In the third embodiment, like the roof tile Y shown in FIGS. 4 (1), (2) and (3), the recessed portion 1 is formed in a part of the bottom portion R, and the side end of the insertion portion U is inserted. The locking projection 2a is provided so as to protrude toward the hanging portion Tu, and the locking projection 2a is formed integrally with the rear surface projection 5 for the purpose of reinforcing it and also serving as a roofing stacking guide. In addition, the bottom surface of the locking projection 2a has an inclination that is substantially parallel to the roof tile base plate N surface with respect to the tile layer, that is, an inclination that is substantially parallel to the surface that forms the return slope of thatched roof tiles. The height is set so as to be in contact with the N plate surface, and a nail hole 4 is formed in this locking projection 2a so that it can be fixed by a nail. It is desirable to provide the small protrusion 3a on a part of the locking protrusion 2a.

Other than that, the structure of the cross section S, the water repellent 9 on the outside of the insertion section U, the drooping section T, the cross section drooping section Ts, the nail hole 10 on the side of the hip R, etc. is the same as that of the roof tile of the first embodiment.

When stacking this roof tile Y, see Fig. 5 (1) (2).
(3) (4) as shown in, small projections 3a formed in a portion of the locking projection 2a of tile Y as an upper overlapping roofing the concave portion 1 of the tile Y ₁ in the lower overlapping roofing is fitted, further Part of it infiltrates. The locking projections 2a are nailed through the nail holes 4 and fixed to the base plate N.

Here, the groups of FIG. 4 to FIG. 5 of the third embodiment show an example of zigzag roofing, but in the case of parallel row roofing, the position of the recessed notch 1 is half the working width of the roof tile. It may be moved to the S side.

In the fourth embodiment, like the roof tile 2Y shown in FIG. 6, the locking projection 2a on the insertion portion U side of the third embodiment is locked with a recess 6 formed in a part of the upper surface thereof. This is a method in which a small projection 3b is provided on the locking projection 2b so that the recess 6 is fitted with a stopper 11 and fixed to the base plate N. It should be noted that since it is possible to easily conceive from now on that a nail hole is provided in the concave portion 6, it may be fixed by nailing.

The fifth embodiment basically has a structure similar to that of the third embodiment like the roof tile Z shown in FIGS. 7 (1), (2) and FIG. 9, but the difference is that the insertion portion U side. The locking projection 2c and the small projection 3c are provided so as to be incorporated in a part of the insertion portion U toward the front end on the head side. The locking projection 2c has the same shape as the locking projection 2a of the third embodiment. Such a nail hole 4 is not provided and the rear surface ridge 5 is not necessary intentionally. In the actual production, the insertion portion U may be slightly widened depending on the circumstances of the existing equipment or the like.

When the roof tiles are piled up, as shown in FIGS. 8 (1) and (2), the locking projections 2c of the roof tiles Z in the upper row are formed in the recesses _{1 on} the bottom R side of the roof tiles Z _{1 in} the lower row. It is inserted, infiltrated and locked, and as shown in FIGS. 9 (2) and (3), the above-mentioned locking and the roof tiles Z ₁ are adjacent to each other between the roof tiles adjacent to each other in the same row. Mutual locking is performed by fitting and mounting on the locking projection 8 of the roof tile Z ₂ .

In the above embodiments, the roof tile having a thick flat plate shape is used as an example, but a roof tile having a flat wave shape is also applicable to the present invention.

(Effect of the Invention) As described above, the effect of the present invention is
Floating and lateral slippage are prevented by the locking connection in the same row and row direction, and the single roof tile itself is prevented from floating from the hanging portion side.
In addition, the floating and lateral slippage between the roofing tiles in the upper and lower rows are prevented, and even when these structures are incorporated, there is no rain leakage from the insertion side, and these combinations can be used as a roofing guide even in thatching work. Since it also plays the role of, the work becomes easier.
