[0002]

2. Description of the Related Art In general, a tiled roof has an excellent appearance, but it has a drawback that the roof tile is displaced due to vibration or the roof tile is peeled off and blown off by a strong wind such as a typhoon. For this reason, various means of roofing have conventionally been taken (for example, see Japanese Patent Application Laid-Open No. 5-98746). An example of this 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 roof tile 1B is overlapped with 0, and a plurality of roof 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 metal fitting 100 is formed in an S shape, when the upper roof tile 1B is about to float, the fixing metal fitting 10 is formed.
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, it is not possible to sufficiently prevent the roof tile 1 from scattering.

The present invention has been made in view of the above conventional problems, and an object thereof is to provide a roof tile fixing metal fitting, a fixing structure, and a roof tile that can sufficiently prevent the roof tile from scattering.

[0006]

In order to achieve the above-mentioned object, the fixing metal fitting of the present invention has engaging notches formed in diagonally opposite corners of the bottom and the head of a roof tile to form a lower roof tile. A plurality of roof tiles are stacked along the lengthwise direction by stacking the heads of the upper roof tiles on the hips, and the lower roof tiles are inserted into the back surface of the crosspiece in the vicinity of the engaging cutouts. A first engaging portion that engages with the cross section of the roof tile, a rising piece that rises upward from the first engaging section along the end surface of the cross section of the upper and lower roof tiles, and this rising piece. The connecting piece portion extending inward from the upper end of the upper portion of the roof tile to the inward direction, and the engaged portion formed on the upper roof tile, which is continuously provided from the connecting piece portion, engages with the connecting tile portion to disperse the roof tile. And a second engaging portion that generates a tensile force along the surface of the upper roof tile in the connecting piece portion when bent, and is bent in the width direction of the roof tile from the rising piece portion. By protruding from the rising piece portion along the engaging cutout portion of the lower roof tile, the fixing metal fitting is prevented from coming into contact with the cutout portion and being displaced in the length direction of the roof tile. And an engaging portion.

According to the roof tile fixing structure of the present invention, the roof tile is fixed by using the above-mentioned fixing metal fittings. In the roof tile fixing metal fitting or the fixing structure, the second engaging portion is bent downward from the tip of the connecting piece portion, is inserted into the groove formed in the upper roof tile, and is engaged with the upper roof tile. Is preferred. Further, it is preferable that the groove is formed to be long in the length direction of the roof tile and is formed as a non-penetrating groove that is open only above.

On the other hand, the roof tile is formed with engaging notches at diagonally opposite corners of the bottom and the head of the roof tile, and the head of the upper tile is overlapped with the bottom of the lower tile to extend along the length direction. Are arranged side by side, the engaged portion that is long in the length direction of the tile is provided on the surface of the cross section of the head of the upper tile that overlaps the lower tile, and this engaged portion has a length of 5 mm or more, Moreover, it has a height of 5 mm or more. The engaged portion is preferably formed by a groove engraved on the crosspiece.

[0009]

In 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, that is, Since the upper and lower roof tiles are engaged with each other at the substantially U-shaped portion, unlike the conventional S-shaped fixtures, even if the upper tiles try to float upward, there is no risk of the fixtures deforming. . 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 engaging portion that abuts the engaging cutout portion of the lower roof tile is provided, there is no risk of the fixing metal fitting being displaced in the length direction of the roof tile (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, the roof tile 1 is a crosspiece, and includes a tail portion 10 and a head portion 11 at an end portion in the length direction L, and a crosspiece portion 12 and an insertion portion 13 at an end portion in the 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 portion 11 of the upper roof tile 1B is superposed on the bottom portion 10 of the lower roof tile 1A, and a plurality of roof 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 bottom portion 10 of each roof tile 1, protrusions 14, 14 that engage with the roof tile rail 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 plate, and if necessary, paints of the same color as the roof tile 1 are fixed to the fixing bracket 30.
May be applied to the surface of the roof so as not to impair the aesthetics of the roof.

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 portion 35 extends inward from the upper end of the rising piece portion 34 along the surface of the upper roof tile 1B. The connecting piece portion 35, the rising piece portion 34, and the first engaging portion 31 described above 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
It is inserted in the groove (engaged portion) 19A formed in the above and is engaged with the engaged surface 19a of the upper roof tile 1B. The groove 19A
2 is a non-through groove that is open only upward, and is formed to be 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. 2, the engaging cutout portion of the lower roof tile 1A. By projecting from the rising piece portion 34 along the line 16, it is in contact with the engaging notch portion 16. 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 fitting 30 is not displaced even above the roof tile 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 engaging bent portion 1b between the 2 and the connecting piece portion 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 structure, the roof tile 1 is prevented from scattering due to the cooperation of the fixing fitting 30 and the nail. Where the roof tile 1
Since the edge portion 12a at the lower end of the beam portion 12 has an acute angle, the first engaging portion 31 of the main fixing fitting 30 engages with the edge portion 12a of the beam portion 12, and therefore the first engaging portion 31.
The bending moment acting on the element becomes extremely small. Therefore, the first engaging portion 31 is difficult to deform. On the other hand, this fixing bracket 3
Since 0 is formed not in an S-shape but in a U-shape,
Even if the upper roof tile 1B tries to float, the rising piece portion 34 is unlikely to be deformed. In particular, since the second engaging portion 32 is engaged with the groove 19A, when the floating force (scattering force) acts on the upper roof tile 1B, the tensile force along the surface of the upper roof tile is applied. 35, there is no possibility that the connecting piece portion 35 will be deformed as shown by the broken line. As described above, the fixing bracket 30 is hard to be deformed even when the upper roof tile 1B is lifted, and thus exerts a sufficient lift preventing 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 an acute angle or a right angle and engaged with a small radius, the engaging bent portions 1a and 1b are work-hardened by press working. It is difficult to deform as it occurs. 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 portion 34 and the connecting piece portion 35 are bent with a large radius at an obtuse angle. 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, the 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 covered. It engages with the engaged surface 19a of the engaging portion 19B.

FIG. 7 shows a third embodiment. In FIG. 7A, the engaging hole 32 is formed in the connecting piece portion 35 of the fixing fitting 30.
The second engaging portion 32 forming a is continuously provided integrally.
As shown in FIGS. 7B and 7C, on the surface of the upper roof tile 1B,
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.
