JPH0558723U - Roof tile nail holes - Google Patents

Abstract

(57) [Summary] [Purpose] To prevent rainwater from entering the nail hole that holds the roof tile on the ground so that the nail can be driven in any direction. [Structure] A recess 4 is provided on the surface side of the roof tile 1. A similar recess 5 is also provided on the back side. A thin wall 6 is provided between them. When the nail is struck, the wall 6 has a hole through which the nail can pass.

Description

[Detailed description of the device]

[0001]

[Industrial application]

 The present invention relates to a nail hole for a roof tile.

[0002]

[Prior Art]

 Sometimes nails are used to fasten roof tiles to the ground. Small holes may be drilled in the roof tile to secure such holes. Since such nail holes may cause rain leaks, infiltration of rainwater, etc., they are usually defined as pores that allow the nails to pass through. Since the direction of the nail is constant in such a nail hole, it has no effect if the groundwork is not in a proper position with a limited base.

[0003]

[Problems to be solved by the device]

 The present invention aims to improve upon such prior art.

[0004]

[Means for Solving the Problems]

 The present invention is a nail hole for roof tiles, characterized in that a concave portion is provided on the front surface side, a concave portion is also provided on the back surface thereof, and thin walls are provided between the bottom surfaces of the concave portions on both front and back surfaces.

[0005]

[Action]

 The nail hole of the roof tile of the present invention has recesses on both front and back surfaces, and a thin wall is provided at the boundary thereof. Therefore, there is no through hole unless the nail is struck. The recess is preferably in the shape of an inverted trapezoid, and the nail can be driven diagonally along the direction of inclination of the recess, so that even if the base is displaced, it can be effectively fastened to the base. Since the concave part is also provided on the back surface, the nail does not have a large chip, and only a hole for the nail hole to pass through the thin wall, and the edge of the nail is not chipped. Unlike conventional nail holes, the direction in which the nail is hit is free, so the hole position is a hidden hole, and rainwater does not penetrate by hitting the nail upward. In addition, since the holes that are not nailed have no through holes due to the thin wall, these nail holes can be provided at any position during manufacturing and do not adversely affect the roof tile manufacturing process.

【Example】

 FIG. 1A shows a roof tile 1 according to an embodiment of the present invention. 1B is a sectional view taken along the line BB of FIG. 1A, and FIG. 1C is a sectional view taken along the line C-C of FIG. 1A. is there. Another embodiment in which the shapes of the nail holes are different from those shown in FIG. 1 (d).

The nail hole 3 is composed of a concave portion 4 on the front surface side, a concave portion 5 on the rear surface side, and a wall 6 at the boundary thereof. In the concave portion 4 on the front surface side, two facing surfaces form a slope having a gentle slope, and a nail can be diagonally driven in a wide angle range 7. The recess 5 on the back side forms a wide range of recess where the tip of the nail sticks out to the back side, and the back side is not chipped off by hitting the nail. The wall 6 is a thin wall, and when a nail is struck, a hole corresponding to the size of the nail is opened, and the wall is not greatly chipped. If the nail is not struck, the thin wall 6 has a small area, so even if it is thin, it has sufficient strength. Therefore, there is no possibility that the wall 6 will fall off, and the rain will not be defective.

[0008]

[Effect of the device]

 According to the present invention, when the roof tile is nailed, the roof tile can be fastened to the ground by striking the nail in the most suitable direction and position for striking the nail.
