[0002]

2. Description of the Related Art In general, a tiled roof is excellent in aesthetics, but has a drawback that the tile is displaced by vibration or the tile is peeled off by a strong wind due to a typhoon or the like and flies. For this reason, various means of roofing have conventionally been taken (for example, see Japanese Patent Application Laid-Open No. 5-98746). This example is shown in FIG.
Shown in

In FIG. 8 (a), a bottom part 1A of a lower roof tile 1A is shown.
The head 11 of the upper tile 1B is superimposed on 0, and a plurality of tiles 1A and 1B are arranged along the longitudinal direction L. The fixing bracket 100 is formed in an S-shape, and has a lower roof tile 1A.
Is engaged with the head 11 of the upper tile 1B to prevent the head 11 of the upper tile 1B from rising.

[0004]

However, in the above-mentioned prior art, since the fixing bracket 100 is formed in an S-shape, if the upper tile 1B tries to float, the fixing bracket 10 will not be lifted.
There is a possibility that the central piece 101 of the “0” may be deformed together with the upper tile 1B as shown in FIG. Therefore, the scattering of the roof tile 1 cannot be sufficiently prevented.

The present invention has been made in view of the above-mentioned conventional problems, and an object of the present invention is to provide a fixing device, a fixing structure, and a crosspiece for a roof tile capable of sufficiently preventing the roof tile from scattering.

[0006]

In order to achieve the above-mentioned object, the present invention provides a fixing device for a tile formed by bending a metal plate , wherein the fixing device faces a butt portion and a head portion of the tile. A notch for engagement is formed diagonally, and the head of the upper tile is overlapped with the bottom of the lower tile to fix a plurality of tiles arranged along the length direction. A first engaging portion that enters the back surface of the crosspiece in the vicinity of the joint notch and engages with the crosspiece of the lower tile; and the first engagement portion along the end face of the crosspiece in the overlapping portion of the upper and lower tiles. A rising piece that rises upward from above, a connecting piece that extends inward from the upper end of the rising piece along the surface of the upper tile, and the connecting piece and the rising piece.

[0008]

[0009]

According to the present invention, the first and second engaging portions that engage with the upper and lower roof tiles are connected by the rising piece and the connecting piece that rise upward from the first engaging portion. The U-shaped portion is engaged with the upper and lower roof tiles, so that unlike the conventional S-shaped mounting bracket, there is no possibility that the mounting bracket will be deformed even if the upper roof tile attempts to float upward. . In particular, since the second engaging portion is engaged with the engaged portion formed on the upper tile, a large engaging force is obtained, unlike when the tile is simply pressed from above. Furthermore, since the third engagement portion is provided to abut on the engagement notch of the lower tile, there is no possibility that the fixing bracket is displaced in the length direction of the tile (the longitudinal direction of the rafter).

[0010]

Embodiments of the present invention will be described below with reference to the drawings. 1 to 4 show a first embodiment of the present invention. In FIG. 1, a roof tile 1 is a cross tile, which has a butt portion 10 and a head portion 11 at an end in a length direction L, and a cross section 12 and an insertion portion 13 at an end in a width direction W. This tile 1
As shown in FIG. 2, as shown in FIG.
7 are formed. As shown in FIG. 1, the head 11 of the upper tile 1B is overlaid on the buttocks 10 of the lower tile 1A, and a plurality of tiles 1 are arranged in the length direction L. Meanwhile, each tile 1
On the insertion portion 13, the crosspiece 12 of the adjacent tile 1 is overlapped. On the back surface of the butt portion 10 of each tile 1, projections 14, 14 that engage with the tile bar 20 are provided. Also, a through hole 15 for inserting a nail (not shown) is
Are formed, and nails are inserted through the through holes 15
The roof 1 is fixed to the roof 20 by driving the roof 1 into the roof.
The above fixing structure is a general one, and the main part of the present invention will be described below.

As shown in FIG. 3, the fixing bracket 30 is formed by bending a single metal plate punched by a press, and includes first to third engaging portions 31, 32, 33, a rising piece portion. 34 and a connecting piece 35. The fixing bracket 30
Is made of a metal plate such as a copper plate or a stainless steel plate, and if necessary, paint of the same color as the
May be applied so that the aesthetic appearance of the roof is not impaired.

The first engaging portion 31 enters the back surface of the crosspiece 12 in the vicinity of the engagement notch 16 in FIG. 1 in the lower tile 1A shown in FIG. They are engaged as shown in FIG. The rising piece 34 rises upward from the first engagement portion 31 along the end face of the crosspiece 12 (FIG. 1) in the overlapping portion 18 of the upper and lower roof tiles 1A and 1B. The connecting piece 35 extends inward from the upper end of the rising piece 34 along the surface of the upper tile 1B. The connecting piece 35, the rising piece 34, and the first engaging portion 31 are formed in a U-shape.

The second engaging portion 32 is bent downward from the tip of the connecting piece portion 35, and is
And is engaged with the engaged surface 19a of the upper roof tile 1B. The above groove 19A
Is formed from a non-through groove that opens only upward, and is slightly longer than the second engaging portion 32 in the length direction L of the roof tile 1 as clearly shown in FIG. Preferably, the length of the groove 19A is 5 mm or more and 30 mm or less, and the depth of the groove 19A is 5 mm or more.

The third engaging portion 33 is bent in the width direction W of the roof tile 1 from the lower end of the rising piece portion 34, and as shown in FIG. By protruding from the rising piece 34 along 16, it is in contact with the notch 16 for engagement. This prevents the fixing bracket 30 from being displaced downward in the length direction L of the roof tile 1. The third engagement portion 33 is sandwiched between the two engagement notches 16 and 17, so that the fixing bracket 30 is not displaced above the roof 1 in the length direction L. Has become.

As clearly shown in FIG. 4, the first engaging bent portion 1a between the first engaging portion 31 and the rising piece 34 is bent at an acute angle, and the lower roof tile 1A is bent. Is engaged with the edge 12a at the lower end of the crosspiece 12. Also, the second engaging portion 3
The second engagement bending portion 1b between the second and the connecting piece 35 is bent at a right angle or an acute angle. On the other hand, the connecting piece 35
The bending portion 1c for deformation between the first bending portion 34 and the rising portion 34 is bent at an obtuse angle, and the bending portions 1a, 1 for both engagement are formed.
It is bent with a radius larger than b.

In the above configuration, the roof 1 is prevented from being scattered by the cooperative action of the fixing bracket 30 and the nail. Here, tile 1
Since the edge 12a at the lower end of the crosspiece 12 has an acute angle, the first engagement portion 31 of the fixing bracket 30 engages with the edge 12a of the crosspiece 12, so that the first engagement portion 31
The bending moment acting on the element becomes extremely small. Therefore, the first engagement portion 31 is not easily deformed. On the other hand, this fixture 3
Since 0 is formed not in an S-shape but in a U-shape,
Even if the upper roof tile 1 </ b> B rises, the rising piece 34 is not easily deformed. In particular, since the second engaging portion 32 is engaged with the groove 19A, when a lifting force (scattering force) acts on the upper tile 1B, the pulling force along the surface of the upper tile is connected to the connecting piece. 35, there is no possibility that the connecting piece 35 is deformed as shown by the broken line. As described above, since the fixing bracket 30 is unlikely to be deformed even if a lifting force acts on the upper tile 1B, it exerts a sufficient lifting prevention force.

Further, in this embodiment, the first engaging portion 31 which engages with the lower tile 1A is bent at an acute angle with a small radius. Roof 1B
Since the second engaging portion 32 engaging with the groove 19A is bent at a sharp angle or at a right angle with a small radius, the bent portions 1a and 1b for engagement harden the work by press working. It is difficult to deform. Therefore, even a thin metal plate exhibits a sufficient locking force, that is, a lifting prevention force.

By the way, when attaching the fixing bracket 30 to the roof tile 1, it is necessary to deform the fixing bracket 30 as shown by a broken line. Here, the rising piece 34 and the connecting piece 35 are bent at an obtuse angle with a large radius. For this reason, since the deformation bending portion 1c does not harden as much as the work hardening, the fixing fitting 30 can be easily elastically deformed as shown by the broken line by pushing the second engagement portion 32 upward. It is excellent in workability because it can be done.

As shown in FIG. 5, the case where the shape of the fixing bracket 30 is changed is also included in the scope of the present invention.

Next, second and third embodiments of the present invention will be described. In the following embodiments, parts different from the first embodiment will be mainly described, and the same or corresponding parts will be denoted by the same reference numerals and detailed description thereof will be omitted.

FIG. 6 shows a second embodiment. As shown in FIG. 6A, the fixing bracket 30 is formed such that the length of the connecting piece 35 is shorter than that of the first embodiment. As shown in FIGS. 6B and 6C, the engaged portion 19B of the upper roof tile 1B is formed by forming a recess having a triangular cross section, and the second engaging portion 32 is It is engaged with the engaged surface 19a of the engaging portion 19B.

FIG. 7 shows a third embodiment. In FIG. 7A, an engagement hole 32 is provided in the connection piece 35 of the fixing bracket 30.
The second engaging portion 32 forming a is continuously provided integrally.
As shown in FIGS. 7B and 7C, the surface of the upper tile 1B is
An engaged projection 19C is provided so as to protrude from the engagement hole 32a.
Are engaged with the engaged surface 19a of the engaged projection 19C.

[0023]

As described above, according to the present invention,
Even if the tile is going to float upward, the fixing bracket is unlikely to be deformed, so that even in a strong wind such as a typhoon, the scattering of the tile can be sufficiently prevented. Further, since the third engaging portion is provided, the fixing bracket does not shift in position.
