Description of the Related Art Barbed wire and needle-shaped strips have been used as a method for preventing harmful animals from invading the fields where agricultural products are cultivated and for preventing outpatients from invading important facilities. It was stretched around piles and installed on the top of fences and wire mesh fences.

質からなる帯状体を敷設する方法である。There are roughly three methods for installing these barbed wires and needle-shaped strips. The first method is to stretch barbed wire or strip that is already stabbed around a pile or the like, and the second method is to stretch the wire rod and then dispose the spine rod on the wire rod. is there. A third method is a method of laying a band-shaped body made of a material that deforms into a barbed shape during the work of stretching.

った。However, in the first method, a dedicated barbed wire manufacturing apparatus is required for processing into a desired shape, or once machined, it is manually bent and raised again. There was a problem in terms of work efficiency because it required a process. In addition, it is difficult to handle because wire rods, needle-shaped strips, and metal barbed plates that already have sharp piercings are manually stretched over the tops of piles, fences, and wire mesh fences. There is a risk that the worker may accidentally come into contact and get injured, and the work efficiency is low.

配設するには設置場所が限定されるものであった。In the third method, a strip-shaped thin plate having a score line processed is wound in advance in a roll shape, unwound sequentially from the end of winding and extended, and the barbed portion is expanded while using the joint portion of each elongated portion as a fulcrum. A barbed body is formed only in the width direction of the strip-shaped thin plate forming a body. This is because barbed bodies exist only in the vertical direction when laid on vertically arranged piles or stanchions, and when laid on a flat surface such as the top of a block fence or directly attached to the ground. Since the body does not protrude, it cannot be used, and the installation place is limited in order to arrange it for intrusion prevention.

A strip-shaped metal plate that constitutes a barbed body stretched around
The first extending diagonally leaving a remaining portion at one end in the width direction
Long holes and mounting holes used for mounting to piles, fences, fences, etc. are sequentially provided, and by pulling the winding start end vertically from the rolled state, it becomes a strip metal thin plate. It is characterized in that a twist is caused to rupture the remaining portion of the one end in the width direction and the barbed body is projected.

として、３６０°の全周にわたって連続的に突起する。According to the present invention, the first elongated hole extending diagonally leaving the remaining portion at one end in the width direction and the mounting hole used for mounting to the pile, fence, fence or the like are machined. In the step of rolling or in the step of winding in a roll, the barbed body has a shape that has not yet been projected, so that it is possible to perform work efficiently without causing a danger to a processing operator or a product inspection operator in the manufacturing process. At the time of laying work, the winding start end is pulled out in a direction perpendicular to the roll-shaped end face from the rolled state. As a result, one twist is generated for each winding of the strip-shaped thin metal plate. This twisting force concentrates stress on the remaining portion of the one end in the width direction, breaking the remaining portion of the one end in the width direction to project the barbed body. As a result, the barbed body continuously projects over the entire circumference of 360 ° around the center line in the lengthwise direction of the pulled out strip-shaped metal plate.

体を突起させることを特徴とする。The strip-shaped metal plate according to claim 2 of the present invention has a width at a position symmetrical to the first elongated hole with respect to a mounting hole used for mounting to the pile, fence, fence, etc. A second elongated hole extending diagonally is formed at the other end of the winding direction, and twisting occurs in the strip-shaped metal plate by pulling the winding start end vertically from the rolled state. Thus, the remaining portions at both ends in the width direction are broken to project the barbed body.

As a result, when the winding start end is pulled out in a direction perpendicular to the roll-shaped end face from the state of being wound into a roll, one per roll of the strip-shaped metal sheet is obtained.
Twisting occurs twice, and due to the concentration of stress on the remaining portion of the end portion in the width direction due to the twisting force, brittle fracture is likely to occur when the remaining portion of the end portion in the width direction is broken. Moreover, the strength of the tip of the barbed body is increased.

である。The strip-shaped metal plate constituting the barbed body of the present invention is used for attaching to a long hole extending diagonally leaving a remaining portion at the end in the width direction and to a pile, a fence, a fence or the like. Due to the shape of the barbed body not protruding during machining of the mounting holes, rolling into rolls, quenching, and storage in hollow containers, processing workers and product inspection Work can be done safely and efficiently without causing any danger to the operator. In addition, it is easy to handle and safe during the transportation process and laying work. When laid, the barbed body can be used for a wide range due to its characteristics of continuously projecting over the entire circumference and 360 ° around the center line in the longitudinal direction. By doing so, the fence on which the strip-shaped metal plate from which the barbed body is projected can be stretched quickly and safely. Further, it can be directly attached to the upper surface of the wire mesh fence or the ground, and can be laid on a flat surface such as the upper surface of the block wall, which has an effect of preventing an intruder as an obstacle. Further, the hardness is increased by performing the quenching process in the width direction of the band-shaped metal plate, and the metal plate is not easily cut and removed by a tool such as scissors.
When withdrawing, remove the pegs and tapping screws to which the strip-shaped metal plate is fixed, and by returning the twist over the entire length, the barbed body protruding due to the twist disappears and it can be easily and safely rewound into a roll. It can be reused.
