DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a windproof clip for a roof tile.

[0002]

2. Description of the Related Art In general, a building roof is constructed by laying roof tiles sequentially from the eaves side of the baseboard to the ridge side so as to wrap them. In particular, in windy areas such as the above, windproofing may be applied to the roof tiles in order to prevent the roof tiles from turning up due to strong winds.

[0003] As a windproof clip of a roof tile used for such windproof construction, the one shown in Japanese Utility Model Publication No. 5-486 has been conventionally known. This wind-resistant clip is integrally provided with a board portion interposed between roof tiles that overlap with each other, and a hook portion that hooks the eaves end of the roof tile from the back side thereof, and fixes the clip. Is rotatably inserted into a through-hole provided in the substrate portion, and is integrated with the clip in advance.

An elastic sheet is fixed to the back surface side of the through hole of the board portion, and by fitting this elastic sheet into a circumferential groove formed at the base of the shaft portion of the nail, the nail is attached to the board portion. It is mounted so that it is rotatable and locked.

[0005]

However, in the above-mentioned prior art, since the nail is attached via the elastic sheet fixed to the back side of the substrate, there is a disadvantage that the material and the manufacturing cost are increased. In addition, since the elastic sheet is fitted into the circumferential groove of the nail, the nail cannot be moved in the axial direction with respect to the substrate while the head of the nail remains in contact with the substrate. In many cases, the clip was damaged by hitting the substrate part by mistake during the hitting.

Furthermore, if the head of the nail is kept in contact with the substrate, the clip often interferes with the nail and strikes the nail in a direction that is not perpendicular to the top surface of the tile, making it difficult to mount the clip. There was a disadvantage. The present invention
In view of such circumstances, it is an object of the present invention to provide a windproof clip for a roof tile that can further reduce the material and manufacturing cost, and can also prevent the clip from being damaged at the time of mounting and simplify the work of mounting the clip.

[0007]

In order to achieve the above object,
The present invention has taken the following technical measures. That is, the invention according to claim 1 integrally includes a substrate portion interposed between roof tiles overlapping each other, and a hook portion for hooking an eaves end of the roof tile from the back side thereof, and In the windproof clip of the roof tile, the head of which is rotatably inserted into the through-hole provided in the board, the head of which is integrated with the head at one end. The shaft part is loosely inserted into the through hole of the substrate part so that a stopper part is formed in the middle part of the shaft part and at a position away from the head, and this stopper part is hooked and the shaft part is A protruding piece for preventing escape from the substrate portion is formed integrally with a peripheral edge of the through hole of the substrate portion.

According to a second aspect of the present invention, in the first aspect of the present invention, the retaining portion is provided away from the head to such an extent that the shaft between the head and the retaining portion can be gripped by a finger. It is characterized by having been done.

[0009]

According to the present invention, the retaining portion 13 is hooked and the shaft portion 6 is secured.
Since the protruding piece 14 for preventing A from coming out of the substrate portion 8 is formed integrally with the periphery of the through hole 12 of the substrate portion 8, there is no need to provide an elastic sheet as in the related art. Further, since the shaft 6A is loosely inserted into the through hole 12 of the substrate 8 so that the head 6B of the driving member 6 can be freely moved away from the surface of the substrate 8, the shaft 6A of the nail 6 can be moved with a finger. When grasped, the board part 8 separates from the head 6B, and the head 6B can be hit with a hammer exactly as in the case of hitting only the ordinary nail 6.

In addition, since the work can be performed with the substrate portion 8 separated from the head 6B at the beginning of nailing, the clip 7 itself does not hinder nailing. According to the second aspect of the present invention, the retaining member 13 is provided so as to be separated from the head 6B to such an extent that the shaft portion 6B between the head 6A and the retaining portion 13 can be grasped by a finger. If the shaft portion 6A on the surface side of the substrate is grasped with a finger, there is almost no possibility of hitting the substrate portion 8 with a hammer.

[0011]

An embodiment of the present invention will be described below in detail with reference to the drawings. 4 and 5, a roof tile 3 is tiled on an upper surface of a base plate 1 serving as a base of a roof of a building via a waterproof sheet 2 made of asphalt felt or the like, and a lower surface of the base plate 1 is covered with rafters 4. Supported.

In this embodiment, each of the roof tiles 3 is substantially flat and wide and has a pentagonal shape.
It is laid up so that it wraps sequentially from the eaves side to the ridge side. Each roof tile 3 is provided with four nail holes 5 penetrating the front and back sides thereof in the width direction, and nails (driving members) 6 inserted from the front side into the nail holes 5 are connected to the base plate 1.
, Each roof tile 3 is fixed to the field board 1.

The means for fixing the roof tile 3 (which is also the means for fixing the clip 7 in this embodiment) may be a driving member in which the head 6B is integrally provided at one end of the shaft 6A. A screw such as a tapping screw or the like other than the nail 6 can be used. FIG. 1 shows a clip 7 for hanging the eaves end of the roof tile 3 to prevent the roof tile 3 from being turned up by a strong wind.

The clip 7 is formed by bending one end of a strip-shaped metal plate into a U-shape, and has a substrate portion 8 interposed between the roof tiles 3 overlapping each other, and an eaves tip of the roof tile 3. A hook portion 9 for hooking the side end from the back side thereof is integrally provided. The hook portion 9 is formed narrower than the substrate portion 8 via a tapered portion cut into a tapered shape, and the tip of the hook portion 9 is slightly upwardly curved so that the roof tile 3 is easily hooked. I have. The substrate section 8 is provided with three reinforcing ribs 10 and 11 bulging upward (upper side in FIG. 3B).
The reinforcement rib 10 at the center extends to the tip of the hook 9.

The reinforcing rib 10 at the center is divided at the center of the substrate portion 8, and a through hole 12 for the nail 6 is provided in a valley 10A where the reinforcing rib 10 is not provided. Therefore, since the head 6B is stored in the valley 10A after the nail 6 is driven,
When the roof tile 3 is superimposed, the head 6B of the nail 6 does not interfere. The nail 6 for fixing the roof tile 3 to the field board 1 is inserted through the center of the board portion 8 in a state where the nail 6 is rotatable with respect to the board portion 8 and is prevented from coming off.

That is, the nail 6 has a shaft portion 6A having a larger diameter than the shaft portion 6A provided at the center of the substrate portion 8 so that the head portion 6B can freely contact and separate from the surface of the substrate portion 8. Through hole 1
2 is inserted loosely from the upper surface side of the substrate portion 8, and a retaining portion 13 is integrally formed at a position in the middle of the shaft portion 6 </ b> A of the nail 6 and away from the head portion 6 </ b> B. This retaining part 1
3 is a large number of steps 6C whose diameter decreases toward the tip.
Is formed in the range from the middle to the tip of the shaft portion 6A, while the periphery of the through hole 12 of the substrate portion 8 is
A plurality of projections 14 are formed integrally with each other to lock the retaining portion 13 and prevent the shaft portion 6A from coming out of the substrate portion 8.

As shown in FIG. 2A, each of the projecting pieces 14 protrudes radially inward from the periphery of the through hole 12 and locks the step 6C at its tip. Is slightly smaller than the outer diameter of the shaft portion 6A, so that the nail 6 can freely move back and forth in the normal direction of the substrate portion 8 in a range where the retaining portion 13 is not formed. . In addition, as shown in FIG. 2B, a large number of triangular projecting pieces 14 may be formed in the circumferential direction of the through hole 12.
The planar shape of the projection 14 is not limited to a trapezoid or a triangle.

On the other hand, in a range where the retaining portion 13 is not formed, the step 6C of the retaining portion 13 closest to the head 6B is formed.
The distance H from the head to the head 6B is set so that the shaft 6A therebetween can be grasped by a finger. Therefore, the head 6B of the nail 6
Is projected to the surface side of the substrate portion 8, the shaft portion 6A protruding to the surface side of the substrate portion 8 can be grasped by a finger. In the case where a screw such as a tapping screw is used as the driving member 6, the screw portion formed on the shaft portion may have the function of the retaining portion 13.

3A and 3B are enlarged cross-sectional views of a portion where the nail 6 is inserted. In FIG. 3A, the projecting piece 14 is warped toward the surface of the substrate portion 8, and in FIG. 14 is formed to be open outward by burring. FIG. 3 (c)
In FIG. 3, the protruding piece 14 is warped to the back side of the substrate portion 8 and
In (d), the projecting piece 14 is not warped. In the case where the protruding piece 14 is opened outward by burring (FIG. 3B), the protruding piece 14 is bent by the head 6B after the nail 6 is driven, and the moisture on the surface of the substrate 8 is reduced. From the through hole 12 to the back surface can be prevented. When the projecting piece 14 is warped to the back side of the substrate section 8 (see FIG. 3).
(C)) The head 6B fits into the through hole 12 after the nail 6 is driven, and the head 6B does not interfere with the subsequent operation.

When the roof of a building is constructed by using the clip 7 having the above structure, the nail 6 integrated with the clip 7 is inserted into the nail hole 5 of the roof tile 3 as shown in FIG. The roof tile 3 is driven into the base plate 1, thereby
And the clip 7 is fixed on the roof tile 3. Then, at this time, the tip (eave end side end) of another roof tile 3 disposed on one eave side is hooked on the hook portion 9 of the clip 7 fixed at the same time as the roof tile 3, and the other roof tile 3
Is positioned with respect to the roof tile 3, and the other roof tile 3 is fixed to the field board 1 using the clip 7 with the nail 6 in the same manner as described above.

At this time, the nail 6 is attached to the substrate 8 of the clip 7.
The nail 6 is attached to the base plate 1
The clip 7 is rotatable on the roof tile 3 even after driving, and the direction of the hook portion 9 of the clip 7 can be freely changed, so that positioning of the other roof tile 3 installed thereafter becomes extremely simple. Then, after that, the above operation is repeatedly performed, and each roof tile 3 may be sequentially laid to the ridge side.

As described above, when the roof tile 3 is fixed to the ground board 1, the clip 7 is attached to the roof tile at the same time.
The fixing work of the roof tiles 3 is almost half as compared with the case where the fixing means is not used, and the labor required for windproofing the roof tiles can be greatly reduced. Further, according to the present embodiment, since it is not necessary to fix the elastic sheet to the substrate portion 8 as in the related art, the material of the clip 7 and the manufacturing cost can be reduced.

Further, since the shaft 6A is loosely inserted into the through hole 12 of the substrate 8 so that the head 6B of the nail 6 can freely come and go from the surface of the substrate 8, the shaft 6A of the nail 6 can be removed. When grasped by a finger, the substrate unit 8 separates from the head 6B. Accordingly, the head 6B can be accurately hit with a hammer as in the case of hitting only the ordinary nail 6, and there is no possibility of hitting the substrate portion 8, so that damage to the clip 7 can be effectively prevented.

In particular, in the case of the present embodiment, the distance H from the retaining portion 13 to the head 6B is set so that the shaft portion 6A therebetween can be grasped by a finger. If the portion 6A is grasped with a finger, there is almost no possibility of hitting the substrate portion 8 with a hammer. In this embodiment,
At the beginning of nailing, the work can be performed with the substrate portion 8 away from the head 6B, so that the clip 7 itself does not hinder nailing, and the nail 6 can be driven more accurately and easily than before. .

In the above embodiment, one roof tile 3
The number of the clips 7 attached to the roof tile 3 depends on the climate of the construction area, and it may not be necessary to attach the clips 7 to all four nail holes 5 of the roof tile 3.

[0026]

As described above, according to the present invention,
Since there is no need to provide a conventional elastic sheet, the material and manufacturing cost of the clip 7 can be reduced, and the head 6B can be hit with a hammer exactly as in the case of hitting only the ordinary nail 6, and Since the clip 7 itself does not hinder nailing, the clip 7 can be prevented from being damaged at the time of mounting, and the mounting operation of the clip 7 can be performed more easily than before.

According to the second aspect of the present invention, by gripping the shaft portion 6A on the front surface side of the substrate portion 8 with a finger, there is almost no possibility of hitting the substrate portion 8 with a hammer. Damage to the clip 7 can be more completely prevented.
