実現できる特殊釘の出現が強く要望されていた
が、現在そのようなものは存在しない。 Conventionally, there are various types of special nails including anchors used for foamed concrete called A, L, and C, but when the material to be driven into is soft and porous, the nail shaft and material cannot be connected to each other. Since the friction between them is small, the pull-out prevention force and shaft rotation prevention force are weak, and a sufficient pull-out prevention effect cannot be obtained. For example, there is a special nail with the above-mentioned pull-out prevention effect called Cut Nail (product name).
A driving shaft with a rectangular cross section has a tapered surface formed on the tip.In this case, the square shaft of the driving shaft stops the shaft rotation, and the tapered surface of the tip increases the friction surface. However, since such nails do not have a wedge effect, if the driven nail loosens even slightly due to vibration, etc., the tapered surface of the tip loses its function as a friction surface against the corresponding material. There is. For this reason, there has recently been a strong demand in the industry for a special nail that will never loosen after being driven into the material, and that can constantly press against the material with its wide friction surface due to its tapered surface to completely prevent the nail from falling out. No such thing currently exists.
本考案は、極めて簡単な構成により上記要望を
満足した新規な特殊釘を提供するものである。 The present invention provides a new special nail that satisfies the above requirements with an extremely simple configuration.
以下図面に示す実施例に基づき本考案を具体的

形成するも可い。 The special nail for foamed concrete of the present invention has a driving shaft 1 having a rectangular shaft cross section and a tapered surface 11 at the tip, and a driving shaft 1 that surrounds three sides of the driving shaft 1 and is fitted from the tapered surface 11 side. It consists of a channel-shaped wedge frame 2 whose upper end is welded and fixed 21 to the driving shaft 1.
The wedge frame 2 is formed, for example, by press working of a stainless steel plate, and the wedge frame 2 is formed by pressing a stainless steel plate material, and has a tapered surface 1 of the driving shaft 1.
Tapered surfaces 23, 23 are formed on the opposite side walls 22, 22 of the so-called channel frame, which are orthogonal to the side surface 1 having the side wall 1. . The side wall 22 having the tapered surface 23 is provided with a protrusion or projection 24 that protrudes inward and is supported on the driving shaft 1.
reinforcement and the inclination angle of the tapered surface 23 are regulated. Such protrusions or protrusions may be formed on the shaft side surface of the driving shaft 1.

The raw end part 12 is formed by molding a synthetic resin material, the intermediate part 14 is threaded into a ready-made stainless steel pipe, and the proximal end part 16 is formed by a rolling method. Mass production is possible by saving labor, and by setting the length of the intermediate portion 14, it can be applied to large and small nails.

る。 However, when driving the special nail of the present invention into a soft material such as foamed concrete, the driving shaft 1 and wedge frame 2 plunge straight into the material without separating at the beginning of driving, and as they advance, the driving shaft 1 The material located in the space between the tapered surface 11 and the wedge frame 2 is compressed, and the compression reaction force causes the tip of the wedge frame 2 to gradually move away from the driving shaft 1 and expand, and when driving is completed, the wedge frame 2 The tip is expanded and separated from the driving shaft 1, and the compressed material bites into the wedge shape in the meantime, preventing the wedge frame 2 from forming. In this state, on the side walls 22, 22 perpendicular to the expanding direction of the wedge frame 2, the tapered surfaces 23, 23
are compressed and in close contact with the material, and in such tapered surfaces 23, 23, the side wall 22 due to compression of the material
The frictional force is strengthened by the multiple forces of , and the compression reaction force of the material, and it achieves complete retention.

実用上の効果は顕著である。 As described above, in the present invention, a matching channel-type wedge frame 2 is fitted from the tapered surface side to a square driving shaft 1 having a tapered surface 11 at its tip. , since the tapered surface 23 is formed on the side surface perpendicular to the side surface having the tapered surface 11 of the driving shaft 1,
By driving into a soft material, the tip of the wedge frame 2 expands and exerts a wedge-shaped pull-out prevention effect and rotation prevention effect, and the wedge frame 2
The tapered surface 23 on the side surface increases the frictional surface with the material and greatly strengthens the pull-off prevention force, which simplifies the structure and has remarkable practical effects.
