【Example】

 An embodiment of the present invention will be described with reference to the drawings.

As shown in FIG. 1, the fall prevention nail 1 according to the first embodiment of the present invention is provided with a flange 3 at a top end of a tubular body 2 and extends from a lower end portion of the tubular body 2. The rod-shaped members 4 are arranged in series. The tubular body 2 is formed by, for example, forming a substantially T-shaped metal plate having a thickness of about 0.5 to 2.0 mm into a cylindrical shape with the longitudinal axis as an axis, and welding the edges. The body 2 and the rod-shaped member 4 are configured. The flange 3 is formed by pressing and crushing the top end of the cylindrical body 2. A nail body 5 having a length longer than the sum of the length of the cylinder body 2 and the rod-shaped member 4 is inserted into the cylinder body 2 thus formed, and the vicinity of the tip 5a of the nail body 5 and the tip 4a of the rod-shaped member 4 are inserted. Are joined by welding or the like so that the nail body 5 projects from the collar 3 of the tubular body 2. The rod-shaped member 4 may be processed into a flat plate shape so as to be easily bent, and the collar 3 may be formed by welding a ring-shaped metal plate.

As shown in FIG. 2, the drop-off prevention nail 1 having the above-described structure is configured such that the tip 5a of the nail body 5 is substantially vertically contacted with a decorative plywood or a tile board that constitutes the building structural material 6 for interior and exterior. When the nail bodies 5 are brought into contact with each other and the top end of the nail body 5 is hit with a hammer or the like, the tubular body 2, the rod-shaped member 4 and the nail body 5 are integrally buried in the interior / exterior building structural material 6. After penetrating the interior / exterior building structure material 6, when it rushes into the base 7 composed of an ALC plate or the like, and the collar 3 provided at the top end of the cylindrical body 2 comes into contact with the surface of the interior / exterior building structure material 6. The cylinder body 2 and the rod-shaped member 4 are prevented from entering, but when the nail body 5 is further hit, the tip 5a of the nail body 5 is connected to the tip 4a of the rod-shaped member 4 and is prevented from entering. Therefore, the tip 4a of the rod-shaped member 4 is pushed by the tip 5a of the nail body 5 and curved outward. At this time, since the portion of the nail body 5 surrounded by the cylinder 2 is not bent, only the portion protruding from the lower end surface of the cylinder 2 is bent. Then, when the nail head 5b of the nail body 5 is locked to the collar 3, the driving is finished with this.

In this way, the drop-preventing nail 1 in which the rod-shaped member 4 and the nail body 5 are curved inside the ALC plate or the like of the base 7 is designed to bite into the base 7 and not be easily removed. The wearing construction material 6 and the base 7 are firmly fixed. Moreover, by changing the length of the cylinder in the longitudinal direction, it is possible to surely bend the inside of the base 7 according to the thickness of the building structure material 6 for interior and exterior.

In the captive nail 1 of the second embodiment according to the present invention, the tip 4a of the rod member 4 and the tip 5a of the nail body 5 of the captive nail 1 of the first embodiment are not joined by welding or the like. As shown in FIG. 3, the tip 4a of the rod-shaped member 4 is bent into a key shape to provide a receiving portion 4b, and the tip 5a of the nail 5 is brought into contact with the receiving portion 4b. By doing so, as shown in FIG. 4, the step of welding the tip 4a of the rod member 4 and the tip 5a of the nail body 5 can be omitted while obtaining the same effect as the first embodiment, and the number of steps is reduced. It leads to reduction.

As shown in FIG. 5, the falling prevention nail 1 of the third embodiment according to the present invention is, for example, a portion of the nail body 5 marked with a mesh line, which is heat-treated to remove the portion. It is hardened. That is, this heat treatment is applied to the portion of the nail body 5 other than the portion to be curved. Therefore, since the portion of the nail body 5 shown in the figure below the mesh line is easily bent, the nail body 5 is securely fixed to the base 7 such as the ALC plate, and the reliability is improved. Since the part of the No. 5 above the brim 3 is hardened, it is hard to bend at that part and it is easy to drive. In the case of brittleness due to high temperature treatment such as ferritic stainless steel, heat treatment is applied to the portion to be bent. Further, in the case of austenitic stainless steel having high ductility such as 18-8 stainless steel, the portion marked with a mesh line in the figure is work-hardened by knurling instead of heat treatment.

As shown in FIG. 6, the falling prevention nail 1 according to the fourth embodiment of the present invention has, for example, a silicone rubber having elasticity and water repellency in the gap between the nail body 5 and the cylindrical body 2. A water-repellent resin material 8 such as the above is applied, and when it is driven in, as shown in FIG. 7, it fills the gap between the nail body 5 and the cylinder body 2 to prevent the infiltration of rainwater or the like. By thus preventing the infiltration of water such as rainwater, it is possible to prevent the materials such as the interior / exterior building structural material 6 or the base 7 from being corroded, and at the time of driving the cylinder body 2 or the nail body 5. Prevents the formation of rust even if cracks occur and the wire material such as iron or copper is exposed from the plated part.
