Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to an improvement of a double wire mesh fence.

[Prior Art] Generally, when a double wire mesh is stretched between the posts in a double wire mesh fence, connecting fittings are attached to vertical lines located at both left and right ends of the double wire mesh, and the connecting fittings are connected to the posts. is being carried out.

However, when connecting fittings are attached to the vertical lines of the double wire mesh in this way, external force in the width direction of the double wire mesh is likely to be applied to the connecting fittings, causing the vertical lines to bend or overlap with the horizontal lines. The welded parts may peel off, and the wire mesh is likely to be damaged.

This kind of problem can be solved by attaching the connecting metal fittings to the horizontal line, but the problem is that the connecting metal fittings tend to slip sideways in the axial direction of the horizontal line due to external force, making the installation of the wire mesh unstable. be.

[Problems to be Solved by the Invention] An object of the present invention is to configure a double wire mesh and a support so that they can be easily and firmly connected using the horizontal lines of the double wire mesh.

[Means for Solving the Problems] In order to solve the above problems, the double wire mesh fence of the present invention is provided with a double wire mesh fence provided with a pair of lattice wire mesh plates consisting of vertical lines and horizontal lines, on opposite sides of the horizontal lines. A curved part that curves concavely toward the inside of the wire mesh is formed at each end, and U-shaped bolts are hooked and fixed to both horizontal lines at the curved parts, and these U-shaped bolts are connected to a common connecting metal fitting. It is characterized in that the connecting fitting is attached to a support post.

[Example] Hereinafter, an example of the present invention will be described in detail based on the drawings.

In FIGS. 1 to 3, numeral 1 indicates posts erected on the ground at regular intervals, and numeral 2 indicates a double wire mesh stretched between the posts 1 and 1.

The double wire mesh 2 has lattice wire mesh plates 2a, 2a each consisting of vertical lines 3 and horizontal lines 4 arranged opposite each other at a constant interval in the front and back. Even if it is formed by bending it in two,
It may also be formed by forming two wire mesh plates 2a, 2a independently and connecting them by appropriate means.

In order to attach the double wire mesh 2 to the support 1, opposite horizontal lines 4 on the front and rear wire mesh plates 2a, 2a,
At the side ends of 4, arc-shaped curved parts 5, 5 are formed by concavely curving the horizontal lines toward the inside of the wire mesh, and wire clips 6 are attached to the curved parts 5, 5, respectively. There is. This wire clip 6 is
It consists of a U-shaped bolt 7 that locks the horizontal wire 4 at the curved portion 5, and a substantially U-shaped fixture 8 for fixing the U-shaped bolt 7.
is provided with notches 9, 9 into which the horizontal line 4 fits at the ends of the pieces 8a, 8a on both sides that contact the horizontal line 4, and these U-shaped bolts 7 and fixtures 8 are tightened with nuts 10. It is fixed to horizontal line 4.

Then, the U in the wire clips 6, 6
The bolts 7, 7 are attached to a common connecting fitting 11 having a substantially U-shape with nuts 12, 12, and the connecting fitting 11 is fixed by tightening the bolt 13 protruding from the support 1 with nuts 14, 15. are doing.

In addition, when providing the above-mentioned curved portion 5, it is also possible to arrange a plurality of horizontal lines closely and provide curved portions on these horizontal lines.In this way, the connection strength of the double wire mesh can be further increased. can be increased.

[Effect of the invention] According to the wire mesh fence of the present invention having the above configuration, curved portions concavely curved toward the inside of the wire mesh are formed at the side ends of the opposing horizontal lines of the double wire mesh. At the curved part, the U-shaped bolts are attached and fixed to both horizontal lines, and these U-shaped bolts are attached to a common connecting metal fitting, and the connecting metal fitting is connected to the column, so the U-shaped bolt can be connected to the horizontal line with a simple structure. The double wire mesh can be firmly fixed to the pillar so as not to slip sideways, and the double wire mesh can be easily and firmly connected to the support column via the U-shaped bolt and the connecting fitting. Moreover, when an external force is applied to the double wire mesh in the horizontal direction (lengthwise direction), as in the conventional method of connecting the wire mesh and the support column using vertical wires, separation may occur at the welded point between the vertical wire and the horizontal wire. There are no bends in vertical lines, etc.
The structure can be such that the wire mesh is less likely to be damaged. Furthermore, since the U-shaped bolts each fixed to a pair of lattice-like wire mesh plates were attached to a common connecting metal fitting,
The pair of lattice-shaped wire mesh plates are connected and integrated with each other by the U-shaped bolts and the connecting metal fittings, and the resulting reinforcing effect has the advantage that the strength of the double wire mesh becomes extremely large. .
