Description

Description: TECHNICAL FIELD The present invention relates to a fence provided with a diamond-shaped wire mesh in which a large number of mesh wires having rings at both ends of a zigzag portion are sequentially knitted.

<Prior Art> Conventional rhomboid wire mesh is generally, as shown in FIG. 11, a large number of first net wire A1 having a first part C1 at both ends of the zigzag portion B1 for rhombus, and the zigzag portion B1. Is formed by sequentially knitting a large number of second net wire A2 having a second ring C2 at both ends of a zigzag portion for rhombus B2 bent in the opposite direction.

The wire mesh of 2 m to 10 m in the expanded state is folded as shown in Fig. 12 when transported from the factory to the construction site.In this state, the first part C1 and the second ring are C2 is configured to deviate by a dimension E corresponding to one side of the diamond.

<Problems to be solved by the invention> For example, a wire mesh of 2 m in the expanded state, the first part C1 and the second ring C2 are about 22 to 23 pieces respectively, but at the construction site, wire mesh as shown in FIG. 11 is used. When expanding about ten times, since the first part C1 and the second ring C2 change from the displaced state to the same level, there is a problem that they are entangled with each other and it is difficult to expand.

After the wire mesh is expanded, the common core wire D is connected to the first part C1 and the second ring C2.
And is stretched between columns and on the furring strip.

Therefore, an object of the present invention is to provide a diamond-shaped wire mesh fence capable of extremely easily performing the work of switching the wire mesh from the folded state to the expanded state.

<Means for Solving the Problem> The problem solving means according to the present invention is, as shown in FIGS. 1, 2, and 3, the first core wire D1 is inserted only in the first part C1, and the second core C2 is second. The core wire D2 is inserted and both ends d11, d12, d21, d21, d21, d21 of the first core wire D1 and the second core wire D2 in the wire mesh folded state and the wire mesh expanded state.
d22 is directly (or indirectly) retained by the first part C1 and the second ring C2 located at the end of the wire mesh, and the first core wire D1 and the second core wire
The length of D2 is set so as to match the expanded state of the wire mesh (about ten times as large as the folded state of the wire mesh), and both ends of the first core wire D1 and the second core wire D2 are attached to the pillar 2 erected on the foundation 1. It is fixed directly or indirectly.

<Operation> In the above means for solving the problem, the first net wire A1 and the second net wire A2 are knitted in the factory as shown in FIG.
And the first core wire D1 and the second core wire D2 are inserted through the second ring C2, the first core wire D1, the ends d11 and d12 of the second core wire D2 are locked, and the first core wire D1 and the second core wire D2 are curled. At the other end, take out the wire mesh in a folded state in which it is prevented from expanding.

Then, the one end side of the first core wire D1 and the second core wire D2 is attached to the pillar 2
, And the upper end of the wire mesh is suspended from the column 2 by the wire rope 4. Next, the first net wire A1 and the second net wire A2 of the folded wire net are expanded by their own weight, and the other ends d12 and d22 of the first core wire D1 and the second core wire D2 which are linearly deformed are attached to the pillar 2. This is fixed, and this work is repeated between a large number of columns 2, and finally the wire rope 4 is attached to complete the construction of the diamond wire fence.

In the above, when expanding the first net wire A1 and the second net wire A2, the first part C1 and the second ring C2 are respectively restrained by the first core wire D1, the second core wire D2, They spread smoothly without being tangled during the expansion.
