Description

[Detailed Description of the Invention] The present invention relates to a wire mesh fence using a twin-barrel wire mesh having two parallel trunks spaced apart.

Conventional chain-link fences are constructed by stretching wire mesh between posts set up on the ground and supported by a rim at the top and bottom. Each post is strongly supported by the rim, but the mesh In wire mesh fences in which double-barreled wire mesh is stretched between the posts by arranging double wire mesh in the front and back, the upper and lower edges are often not provided with rims. The supporting force was extremely weak, and the wire mesh was also extremely weak against external forces.

The present invention was developed in view of the above-mentioned problems.In a wire mesh fence using a twin-barrel wire mesh having two parallel trunks spaced apart, a support line made of wire rope or the like is connected between the posts between the two trunks. The feature is that the pillars and double-barrel wire mesh can be firmly supported by inserting and tensioning them between them.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings. In FIGS. 1 to 4, 1,
1, . . . are struts, 2, 2, . . . are double-barrel wire meshes, and the double-barrel wire meshes are made by cross-abutting a large number of vertical strands 3 with horizontal strands 4 perpendicular to them. By welding and integrating the abutting portions by electric resistance welding or the like, a grid-like net is formed, and by bending the grid-like mesh into an inverted U-shape, two parallel barrels are formed with an interval between them. It is formed to have portions 2a, 2a and a connecting portion 2b that connects their upper ends, and the lower end of the twin-barrel wire mesh 2 is provided with a vertical strand 3 by extending the lower end as necessary. Connecting parts 2c are formed by adhering to the opposing trunk sides, and connecting fittings 5 are attached to both ends of the twin-barrel wire mesh 2.

The connecting fitting 5 is provided with two upper and lower semi-cylindrical clamping pieces 7a and 7b curved in opposite directions at both ends of the plate-like body 6, and a connecting hole 8 is formed in the approximate center of the plate-like body 6. The clamping pieces 7a, 7b are attached to the vertical wires 3, 3, which are located at the ends of the two body parts 2a, 2a and face each other in the same phase.
It is constructed between these vertical strands 3, 3 by elastically clamping them.

When installing the fence, threaded mounting rods 9 are passed through the pillars 1 in the left-right direction and fixed with nuts 10. The connection hole 8 of the connection fitting 5 in , 2
By inserting the connecting fittings 5 and the mounting rods 9 into the holes and fixing them with nuts 11, 11, the double-barreled wire mesh 2 is stretched between the pillars 1, which are set up on the ground at appropriate intervals. Next, support lines 12 made of wire ropes, rods, etc. are stretched between the upper and lower positions between each support, and at this time, the support lines 12 are
It is inserted between the two body parts 2a, 2a and brought into contact with the inner surfaces of the upper and lower connecting parts 2b, 2c,
In this state, each column 1 is inserted into the insertion hole drilled in the side surface of the column 1 and fixed with a locking piece 13 such as a nut.
to be locked. The support wire 12 does not necessarily need to be stretched above and below the support 1, and may be stretched only at the upper end.

In addition, 14 in the figure is a connecting fitting between support wires, 15
1 is a cap attached to the head of the support column 1, and 16 is an annular metal fitting fitted to the lower support line attachment position.

According to the wire mesh fence configured as described above, the following unique effects can be expected by using the twin-barrel wire mesh and the support wires together.

(a) Double-barrel wire mesh consisting of a lattice-like mesh body is particularly vulnerable to forces in the direction of crushing the mesh into a diamond shape. When the wire mesh is bent downward, the force in the direction described above acts on each strand, which tends to cause the wire mesh to break due to peeling. However, in this invention, the support wire stretched between the supports Therefore, since the connecting portion of the double-barrel wire mesh is supported from the inside, the support can prevent the double-barrel wire mesh from being bent downward,
Thereby, damage to the wire mesh due to peeling of the strands can be suppressed as much as possible.

(b) Since the support wire is inserted into the space between the two bodies while in contact with the inner surface of the top of the connecting part, it is not possible to support the double body wire mesh in the direction perpendicular to the mesh surface. It is possible to provide a certain degree of freedom, thereby making it possible to exhibit good cushioning properties against forces in a direction perpendicular to the mesh surface, which is an advantage of the twin-barrel wire mesh.

In addition, when a large acting force that causes deformation exceeding the above degree of freedom is applied to the twin-barrel wire mesh, the body of the twin-barrel wire mesh is supported by contacting the support line, so that The supporting force will work effectively.
