DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an inexpensive barbed wire which can be laid quickly and easily, and a method and a device for laying the barbed wire.

[0002]

2. Description of the Related Art FIG. 8 shows an example of a conventional wire mesh. This is because many piles 1
And a plurality of barbed wires 2 are locked to the respective piles 1 one by one by a locking metal fitting 3. In this case, a barbed wire is used so that the body is not damaged by the barbed wires 2. a must be carefully laid, and the laying takes time and effort.

As a solution to the above drawback, as shown in FIG. 9, one end of a bellows-shaped barbed wire 2 hung on a hanger 5 on a vehicle 4 is extended and fixed to the ground, and then the vehicle 4 is run. In some cases, the bellows-like barbed wire 2 is pulled out from the hanger 5 and a wire mesh a is laid.

[0004]

In the above-described configuration, the laying of the barbed wire a can be performed quickly and easily.
It is necessary to use a high-quality spring wire as the iron wire, and to use a special shape as a barb protruding from the iron wire so that adjacent iron wires do not become entangled with each other, resulting in high manufacturing costs.

[0005] In view of the above problems, an object of the present invention is to provide an inexpensive barbed wire that can be laid quickly and easily, and a method and an apparatus for laying the barbed wire.

[0006]

Means for Solving the Problems In order to achieve the above object, the invention according to claim 1 comprises a plurality of columns erected at predetermined intervals and a barbed wire erected between the columns. The iron wire mesh is characterized in that the pillar is constituted by a pair of frame members arranged in an inverted V-shape, and upper ends of both frame members which are opposed to each other are rotatably connected by hinges.

In the above configuration, the barbed wire is wound up in a roll shape in a state where each of the pillars is expanded by rotating both frame members around the hinge, whereby the wire mesh can be stored compactly. In addition, it is possible to lay the wire mesh quickly and easily by unwinding the wire mesh in the stored state, turning both frame members around the hinge, bending each of the pillars into an inverted V shape, and grounding. it can.

[0008] In this case, since a large number of pillars made of both frame members of the barbed wire and the barbed wire are integrally connected in advance,
The barbed wire can be laid quickly and easily. Also,
Since the support pillar is formed in an inverted V-shape and both ends are grounded, it is hard to fall down, and a strong wire net can be formed. Further, a commercially available barbed wire can be used, and the production cost can be reduced.

By striking the stake movably engaged with the stake, the support composed of the two frame members can be easily fixed to the ground.

According to a fifth aspect of the present invention, in the fourth aspect of the present invention, the pair of link mechanisms are provided with a barb, and the two frame members are turned around the hinge to form an inverted V-shape. Thus, the barb is made to protrude outward from both frame members.

According to the above configuration, since the barbs protrude outward from the two frame members formed in the inverted V shape, the function as a wire mesh can be further improved. Further, by rotating the two frame members around the hinge to bring them into the unfolded state,
Since the barb is immersed inward from the support, the barbed wire can be easily wound.

According to a sixth aspect of the present invention, there is provided a method for laying a wire net comprising a plurality of columns which can be bent from a center portion arranged at predetermined intervals and a barbed wire is laid between the respective columns. Draw out a wire mesh from a wire mesh roll formed by winding up the barbed wire in a state where each of the struts is deployed, and fold each of the struts of the drawn wire mesh from a central portion into an inverted V-shape. It is characterized in that both ends are grounded, and the grounded ends are fixed by stakes so that the columns are erected at predetermined intervals.

According to the above configuration, the wire mesh drawn from the wire mesh roll can be laid quickly and easily. The invention according to claim 7 is an apparatus for laying a barbed wire in which a number of columns that can be bent from a central portion are arranged in parallel at a predetermined interval, and a barbed wire is erected between the columns. It has a vehicle equipped with a wire mesh roll formed by winding the barbed wire in a state where the support is deployed, and a guide frame having an inverted V-shaped cross section is extended rearward from the vehicle,
Each pillar of the wire mesh drawn from the wire mesh roll is bent into an inverted V-shape by the guide frame, and both ends thereof are grounded.

According to the above configuration, the vehicle is advanced with the end portion of the wire mesh pulled out from the wire mesh roll on which the vehicle is mounted passing over the guide frame fixed to the ground, so that the drawn wire mesh is drawn out. Can be automatically laid by bending it into an inverted V-shape.
