ことができる特殊釘に関する。[Detailed explanation of the invention] (Industrial application field) This invention has a strong holding force against pull-out for base materials with low elasticity such as foamed concrete, and also has a strong hold on the nail head in the axial direction after driving. This invention relates to a special nail whose head can be easily removed by applying a right-angled force.

としたものが使用されていた。(Prior art) Conventionally, nails with strong holding power against pull-out for base materials with low elasticity, such as foamed concrete, have been divided into multiple nail legs, and after driving, the nail legs are separated from each other at the tip. Those configured so that they are held open from each other at the sides, or whose legs are square shafts,
The shaft side was tapered over almost the entire length.

きないという欠点を有していた。(Problem that the invention aims to solve) However, in any case, in order to ensure strong holding force against base materials with little elasticity, the length of the leg body driven into the base material must be is required,
Short legs have almost no effect. On the other hand, if it is necessary to remove the nail after completion of driving for repair or other reasons, and it is difficult to pull it out by applying axial force because there is an obstacle to pulling it out above the nail head. By applying force perpendicular to the nail axis from the lateral direction of the head, the nail is removed while being forcibly bent, and unnecessary parts held by the nail are sometimes removed. However, the conventional nails mentioned above cannot have short legs due to the need for holding force, and have to be made long. If you try to remove the nail by just applying it, it will only bend the nail shaft near the head, making it impossible to pull it out or remove it any further, unless you remove the obstruction above the nail head and apply a pulling force in the axial direction. This had the disadvantage that unnecessary parts could not be removed.

The purpose is to provide special nails that can.

The head body 4 has a leg body 1 formed over the entire length, a head body 5 and a shaft part 6, and on the outer periphery of the shaft part 6 of the head body 4,
An annular notch recess 7 is provided in the circumferential direction, and a large diameter portion 8 on the side of the head 5 from the notch recess 7 of the shaft 6 has a larger diameter than the inner diameter of the base of the leg 1; The tip side has a small diameter portion 9 having approximately the same diameter as the base inner diameter of the leg body 1.
The base of the leg 1 is externally fitted and fixed to the small diameter portion 9 of the head body 4 so that the end surface of the base of the leg 1 contacts the end surface of the large diameter portion 8 on the notch recess 7 side in an annular manner. It is in the point that it is.

には影響を与えず支障なく打込める。(Function) The leg 1 of this nail is a pipe body with a conical depression 2 with the apex at the base side, so when it is driven into a base material with low elasticity such as foamed concrete, the base material becomes conical. A strong holding force can be obtained by being compressed and held in the recess and by the elastic effect of the leg body 1 made of a pipe body. When it becomes necessary to remove the nail after driving, the shank of the head body 4 can be removed by applying a force acting perpendicularly to the axial direction on the head 5 under conditions in which it is impossible to pull out the nail in the axial direction. 6 has a notched recess 7 in the circumferential direction, and is bent from the notched recess 7, and furthermore, the shaft 6 that receives the leg 1
A break occurs due to the lever action between the head body 4 and the leg body 1, and the head body 4 is separated. When driving, the base side end surface of the leg 1 is located at the large diameter portion 8 closer to the head 5 than the notch recess 7.
Since it is in pressure contact with the end face on the notch recess 7 side and is received there, the force that acts during driving is applied to the notch recess 7.
It can be typed without any problem without affecting.
