Description

[Technical field] The present invention relates to a structure for fixing roof tiles with nails, and more specifically, for providing packing between the nail head and the roof tile, suppressing the protrusion of the packing. The present invention relates to a technique for trying to maintain a stable sealing effect for a long term by packing.

[Background Art] Conventionally, although the roof tile 7 is fixed to the fixing member 9 by interposing the packing 4 using the nail A as shown in FIG. 5, the nail head 2 is substantially flat. As shown in FIG. 6, the outer peripheral portion of the packing 4 protrudes from the nail head 2 as a result of the driving, and the packing 4 portion between the roof tile 7 and the nail head 2 is small, and it is difficult to obtain a sufficient sealing effect. The cushioning effect due to is small, the roof tile 7 may be cracked when the nail A is driven in, and the protruding packing 4 portion is exposed to direct sunlight and wind and rain, which causes various problems such as early deterioration.

[Object of the Invention] The present invention has been made in view of the above problems,
The purpose is to prevent the packing from sticking out to maintain a sufficient sealing effect due to the packing over a long period of time, and to provide a roof tile fixing structure that does not crack the roof tile when driving nails. To provide.

DISCLOSURE OF THE INVENTION In the fixing structure, the pressing band 3 is formed by bending downward from the entire circumference of the annular outer edge portion of the flat plate-shaped nail head 2 provided on the upper portion of the nail main body 1 in a substantially perpendicular direction, Only the upper half 5 of the packing 4 which penetrates the nail main body 1 and has an outer diameter substantially equal to the inner diameter of the flat plate-shaped nail head 2 is provided with the pressing band 3.
The lower half 6 of the packing 4
When the nail main body 1 penetrates through the mounting hole 8 of the roof tile 7 and is fixed to the fixing material 9 by fixing the outer peripheral portion of the pressing band 3 to the lower position of the lower edge of the pressing band 3, the pressing band 3 is pressed.
The outer peripheral upper surface portion of the packing 4 is pressed by the lower edge of the packing 4 and the lower surface of the packing 4 is pressed against the upper surface of the roof tile 7, and the above-mentioned object is achieved by such a configuration. . That is, only the upper half portion 5 of the packing 4 is held inside the presser band 3 formed by being bent downward at a substantially right angle from the entire circumference of the annular outer edge portion of the flat plate-shaped nail head 2, While suppressing the upper half 5 of the packing 4 from protruding outward from the inside of the pressing band 3,
The outer peripheral portion of the lower half portion 6 of the packing 4 is projected to a position below the lower edge of the pressing band 3, and the outer peripheral upper surface portion of the packing 4 is pressed by the lower edge of the pressing band 3 to lower the lower surface of the packing 4 to a roof tile. By pressing it against the upper surface of 7, the packing 4 is strongly pressed against the nail main body 1 and the packing 4 is moved to the roof tile 7
The sealing effect can be enhanced by press-fitting into the surface of the roof and its mounting hole 8 and, moreover, a sufficient cushioning effect can be exerted in the thickness direction of the packing 4 without causing cracking of the roof tile 7. Moreover, since there is no protrusion of the packing 4, it is possible to reduce the exposure of the outer peripheral portion of the packing 4 to direct sunlight and wind and rain, suppress the deterioration of the packing 4, and sufficiently enhance the sealing effect of the packing 4 as a whole. It is intended to maintain the condition for a long time.

Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

A nail head 2 is integrally formed on the upper portion of the nail body 1. Nail head 2
Is approximately circular. A pressing band 3 is hung from the annular outer edge of the nail head 2. The packing 4 has a disk shape that is substantially equal to the outer diameter of the nail head 2. Then, the nail main body 1 is penetrated through the packing 4 and the nail main body 1 is driven into the fixing material 9. In such a case, the upper half 5 of the packing 4 having an outer diameter substantially equal to the outer diameter of the nail head 2 is pressed down. The lower surface of the lower half portion 6 of the packing 4 which is held in the interior of the packing member 3 and is pressed down by the flat plate-shaped nail head 2 so as to project to the lower position of the lower edge of the pressing band 3 is pressed against the upper surface of the tile 7. As shown in FIG. 3, part of the lower surface 6 of the lower half of the packing 4 is press-fitted into the upper edge portion of the roof tile 7 in the mounting hole 8. According to such a configuration, the upper half 5 of the packing 4 is held by the annular pressing band 3 and the upper surface of the lower half 6 of the packing 4 is pressed against the roof tile 7 by the pressing band 3, whereby Since the protrusion of 4 is suppressed and the protrusion of the packing 4 is suppressed in this way, the packing 4 is strongly pressed against the nail main body 1 and the packing 4 is press-fitted into the surface of the roof tile 7 and the mounting hole 8 thereof to obtain a sealing effect. The roof tile 7 has a high height and a sufficient cushioning effect in the thickness direction of the packing 4.
Since the packing 4 does not crack and the packing 4 does not protrude, the exposure of the outer peripheral portion of the packing 4 to direct sunlight or wind and rain is reduced, and deterioration of the packing 4 is suppressed.
The state in which the sealing effect of the packing 4 is sufficiently enhanced is maintained for a long period of time.

FIG. 4 shows another embodiment, in which the nail main body 1 and the nail head 2 are formed as separate bodies, and both are caulked and fixed.

[Effects of the Invention] In summary, according to the present invention, the upper half of the packing is provided inside the presser band formed by bending the annular outer edge of the flat plate-shaped nail head downward at a substantially right angle. While holding, the outer peripheral part of the lower half part of the packing is projected to a position below the lower edge of the presser band, and the lower peripheral edge of the presser band presses the outer peripheral upper surface part of the packing so that the lower surface of the packing is By pressing it against the upper surface, the packing can be pressed strongly against the nail main body, and the packing can be pressed into the roof tile surface and its mounting holes to enhance the sealing effect, and yet a sufficient cushioning effect in the packing thickness direction can be achieved. Since it can be demonstrated, there is no cracking of roof tiles, and there is no protrusion of packing, it is possible to reduce the exposure of the outer peripheral part of the packing to direct sunlight or wind and rain. In addition, there is an advantage that deterioration of the packing can be suppressed and a state in which the packing has a sufficiently high sealing effect for a long time can be maintained.
