Abstract

<P>PROBLEM TO BE SOLVED: To stop the flow of a spray material and to considerably improve impact absorbing ability by thickening the thickness of the front and rear faces of a wire mesh. <P>SOLUTION: The wire mesh is provided by bending one wire rod 3 to form linear rods 1 arranged parallel at equal spaces with fixed length, and bent rods 2 of angle shape having middle angle parts projected on one face side while the adjacent one-direction end and other-direction end of each linear rod are connected thereto, and juxtaposing a large number of such wire rods to knit so that the bent parts between the linear rods and the bent rods in the adjacent rows are entwined. <P>COPYRIGHT: (C)2009,JPO&INPIT

Description

  This invention is intended for stabilization of slopes that face highways and various facilities created by the open cut construction method, etc., slopes that may collapse, fences for falling rock protection, ballproof nets and greening of wall surfaces, etc. Related to wire mesh used for

If the slope is left as it is, the topsoil may be washed away by rainwater or other sewage, or may collapse, so a slope stabilization method that stabilizes the slope is necessary.
As the slope stabilization method described above, first, a wire mesh is laid on the slope, and the laid wire mesh is stopped by an anchor pin that is driven toward the slope.

Next, a spray material, for example, seed mixed soil as a vegetation base material, is sprayed on the wire mesh, or mortar is sprayed to stabilize the slope.
At that time, a wire mesh is buried in the spray material (Patent Document 1).
JP 2005-155163 A

  By the way, the wire mesh used for the slope stabilization of Patent Document 1 is configured by entwining adjacent bent portions of the parallel wires bent in a zigzag shape (in parallel), and the size between the front and back surfaces of the wire mesh is small. That is, the thickness of the wire mesh is thin.

When using such a thin wire mesh, if the thickness of the spray material sprayed so that the wire mesh is buried is thick, the thickness of the wire mesh is so thin that the catching resistance of the spray material is only at the bottom of the layered spray material, so the surface layer portion is Flowing downward (due to sagging with the flow), the spraying thickness of the spraying material cannot be increased and is subject to restrictions. That is, the thickness of the spray material is reduced.
Then, there is a problem with the target slope stability.

Moreover, as shown in Patent Document 1, a rod-like brush is passed through the wire mesh so as to cross the slope, thereby stopping the spraying material from flowing down.
However, there are problems in that it takes a lot of time to penetrate the brush, and the cost is greatly increased.

Furthermore, even if the net is used for purposes other than the above, such as a net for protection such as falling rocks or a ball-proofing, there is a problem such as weakness against impact due to thinness between the front and back surfaces of the above-mentioned net, such as greening The problem that the plant is difficult to get entangled even when used in the sewage.
Therefore, the present invention is to provide a wire mesh that solves the above-mentioned problems.

  In order to solve the above-described problems, the present invention provides a straight rod having a constant length and parallel to each other, and an adjacent one-direction end and the other-direction end of each straight rod are connected to each other. An angle-shaped bent rod with an intermediate peak protruding from the side is formed by bending a single wire, and a large number of these wires are juxtaposed so that the bent portions of the linear rod and the bent rod in the adjacent row are intertwined. A configuration organized as above is adopted.

  As described above, according to the wire mesh of the present invention, the parallel wire of the wire mesh knitted with the bent portions entangled with each other has a certain length and straight ridges arranged in parallel at equal intervals, and adjacent ones of the straight ridges. Since one end of the wire mesh is formed by bending a wire rod with a mountain-shaped bent rod with an intermediate peak protruding from one surface while the direction end and the other direction end are connected to each other, The other side of the wire mesh becomes a chevron-shaped projecting surface, and the dimension between both surfaces of the wire mesh is extremely thick (depending on the degree of protrusion of the bent hook).

Then, if it is used for slope stabilization by burial of spraying material, the spraying thickness of the spraying material can be greatly increased, the effect of improving the slope stability is improved significantly, and the bending where the downstream flow of the spraying material is buried in the spraying material Demonstrate the unique effect of blocking.
Of course, as the thickness of the wire mesh increases, the gap between both surfaces of the wire mesh also greatly increases, so that the inflow of the vegetation greening base material and the dispersion and inflow of wood chips and the like are facilitated.

  In addition, when used in rockfall protection nets, guard fence wire nets, rockfall prevention nets, ballproof nets, etc., the presence of bent ridges greatly increases the impact absorption capacity and remarkably reduces damage and breakage due to impact. Furthermore, when used for greening of the wall surface, the wire mesh can be fitted to the wall surface by contacting the flat straight side of the wire mesh with the wall surface.

Embodiments of the present invention will be described below with reference to the accompanying drawings.
In the embodiment of the present invention, as shown in FIG. 1 and FIG. 2, straight ridges 1 arranged in parallel at equal intervals and at equal intervals, and adjacent one-direction ends and other-direction ends of the respective straight ridges 1 Are connected to each other, and a mountain-shaped bending rod 2 with an intermediate peak protruding from one side is formed by bending one wire 3.

  A large number of the above-described wire rods 3 are juxtaposed, and the wire mesh A is formed by knitting so that the one side wire rod 3 in the adjacent row and the coupled bent portion 4 of the straight rod 1 and the bent rod 2 of the other wire rod 3 are intertwined.

  The wire mesh A configured as described above is, for example, a slope stabilization method, and the wire mesh A is laid on the slope 11 as shown in FIGS. 3 and 4, and the wire mesh A is stopped by anchor pins 12 that drive the slope 11. At that time, the straight rod 1 is brought into contact with the slope 11 side.

Next, the spray material B is sprayed so that the wire mesh A is buried. At that time, the flow of the spray material B in the downstream direction is stopped by the bending rod 2 protruding on the surface side of the wire mesh A.
As the above-mentioned spray material B, there is a customer land such as mortar and greening as is known.

As another example of use, as shown in FIG. 5, a wire mesh A is stretched between the poles 21 by a stopper 22 for falling rock protection or a protective fence.
At that time, the bending rod 2 is positioned on the mountain side for absorbing the impact. Of course, the bent rod 2 that protrudes on the opposite side of the road surface is positioned to prevent catching.

  Furthermore, as another example of use, as shown in FIG. 6, for greening of the wall surface 31, a wire mesh A is attached to the wall surface 31 via an anchor pin 32, and a greening material C is sprayed so that the wire mesh A is buried.

  At that time, the linear fence 1 is brought into contact with the wall surface 31, the wire mesh A is fitted to the wall surface 31, and the bent collar 2 is positioned on the surface side. Naturally, the flow of the greening material C sprayed by the bending rod 2 is stopped, and the spraying thickness is increased.
