Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to an improvement of a multiple wire mesh having a plurality of wire mesh surfaces.

[Prior Art] For example, as disclosed in Japanese Utility Model Publication No. 58-53403, a double wire mesh provided with two wire mesh surfaces at regular intervals has been conventionally known. This double wire mesh not only has a solid feeling and improves the appearance of the fence, but also because it has high strength and elasticity, it improves safety at the time of a collision, and vegetation belts are provided along the road and around houses. In some cases, it can be effectively used as a vegetation-protection wire net for protecting plants, and has many advantages that cannot be imagined with conventional single wire nets.

However, since such a double wire mesh is thick, the wire mesh is difficult to bend, for example, when it is installed in a state of being bent into an L-shape or other shape, or a rod rod crossing the wire mesh surface. There is a problem that the rod sticks out to the side of the wire netting easily when it is fixed to the column, and it becomes a hindrance.Furthermore, if the distance between the two wire netting is constant, the fence is likely to be monotonous and changes in design. There is also a problem that you can not get a rich fence.

[Problems to be Solved by the Invention] The problem to be solved by the present invention is to solve the above-mentioned problems of the related art, to be easily bent, and when the rod rod is attached to the rod rod, the rod rod may largely protrude to the side surface. The purpose of the present invention is to provide a multi-layer wire mesh that can be attached without being present and is excellent in design.

[Means for Solving the Problems] In order to solve the above problems, the present invention provides a constricted portion having a small mesh thickness by forming a recess in the mesh surface in a multiple mesh having a plurality of mesh surfaces. It is a feature.

[Operation] By fitting the rod rod inside the recess in the constricted portion, the rod rod can be attached to the side face of the wire mesh without largely protruding.

Further, by bending the multiple wire mesh at the constricted portion, the bending can be easily performed.

Embodiments Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1 shows a multiple wire mesh with a constricted portion according to the present invention. This wire mesh 1 has a plurality of wire mesh surfaces 1a, 1a made of welded wire mesh plates in which intersections of vertical and horizontal strands 2, 3 are welded. The concavity 5 having a small mesh thickness is formed by providing the depressions 4, 4 in a part of the wire mesh surfaces 1a, 1a.

One or a plurality of the constricted portions 5 may be provided at appropriate positions on the wire mesh surfaces 1a, 1a in the horizontal direction, the vertical direction, or both directions.
Further, the shape of the depression 4 is not limited to the arc shape as shown in FIG. 1, but is V-shaped (FIG. 2), U-shaped, saw-toothed, trapezoidal (third-shaped).
It may be an appropriate shape such as a drawing) or a combination thereof. Furthermore, the wire mesh surface in the constricted portion 5
The wires in 1a and 1a may be brought into contact with each other or may be separated from each other.When they are brought into contact with each other, by connecting them with an appropriate metal fitting, the strength of the wire mesh can be increased. it can.

Further, when forming a plurality of wire mesh surfaces 1a, 1a, one wire mesh plate may be bent and the leading end portions thereof may be connected as necessary, but separately formed wire mesh plates are separated by a predetermined distance. And face each other and connect them by abutting each other on at least one side of the upper and lower ends and the left and right ends, and in any case, the two wire mesh surfaces 1a, 1a may be connected to each other at an intermediate position as needed. it can.

FIG. 4 and FIG. 5 show that the wire mesh surface 1a, 1a is formed with a constriction 5 in a lateral direction, and a pair of horizontal rods 7, 7 is fitted inside the recess 4 to form the horizontal rod 7a. The fence is formed by sandwiching the wire netting 1 between the rods 7 and 7 and connecting both ends of the horizontal rods 7 and 7 to the columns 8. In this case, it is possible to use horizontal rods 7, 7 having a cross-sectional shape that matches the shape of the recess 4, and the wire mesh 1 is connected to at least one of the horizontal rods 7 or the columns 8 by an appropriate connecting metal fitting. Can be kept.

6 and 7 show that a constricted portion 5 is formed vertically on the wire mesh surface 1a, and a pair of vertical rods 10 and 10 that form a column are fitted and fixed inside the recess 4. Thus, there is shown a fence in which the wire netting 1 is stretched directly on the support pillar without using the horizontal rod rod as described above.

As described above, by fitting the rod rod inside the recess 4 in the constricted portion 5, the rod rod can be attached to the side surface of the wire netting 1 without largely protruding. in this case,
A rod rod having a cross-sectional shape adapted to the shape of the depression 4 can be used.

FIG. 8 shows a fence in which the wire netting 1 is bent at a part of the constricted portion 5 and is attached to the column 13 by an appropriate connecting metal fitting 12. In FIG. 9, the wire netting 1 is formed into a plurality of constricted portions. The bent part is shown in FIG.

It should be noted that the above-mentioned constricted multi-mesh 1 can be connected to a column by using an appropriate connecting fitting without using the rod rod as described above and without bending it. Needless to say.

Further, in each of the above-mentioned embodiments, the constricted portion 5 is formed by forming the depressions 4, 4 at the positions where the wire mesh surfaces 1a, 1a face each other. However, as shown in FIG. The depressions 4, 4 may be formed at different positions of 1a, or the depressions may be formed only on one of the wire mesh surfaces. In these cases, the wire mesh is attached using a single rod rod without using a pair of rod rods facing each other.

The wire mesh 11 of the embodiment shown in FIG. 11 is formed by forming the wire mesh surfaces 11a, 11a, 11b in three layers and forming the constricted portion 15 by providing the recesses 14, 14 on the outer wire mesh surfaces 11a, 11a. , Each wire mesh surface
11a, 11a, 11b are connected to each other at appropriate positions in the upper and lower ends and in the middle. The inner wire mesh surface 11b does not have to be provided on the entire wire mesh, but may be provided only on a part of the top, bottom, left, right, or the middle, and the inner wire mesh surface 11b can be formed by a wire rod instead of a wire mesh plate.

In the embodiment shown in FIG. 12, the wire mesh surface 21b is formed by attaching a plurality of wire mesh plates whose upper and lower ends are bent to the wire mesh surface 21b on both sides of the wire mesh surface 21b located at the center at appropriate intervals.
A and 21a are formed, and a constricted portion 25 is formed between the wire mesh plates. In this case, various wire meshes or pipe members 26 made of metal, synthetic resin or the like may be attached to the upper and lower ends of the wire mesh surface 21a.

The wire mesh in each of the above embodiments is not limited to a welded wire mesh composed of vertical and horizontal strands, but may be formed of other crimp wire meshes, expanded metal wire meshes, diamond wire meshes, hexagonal wire meshes, and the like.

[Effects of the Invention] As described above, according to the present invention, since the constricted portion having a small mesh thickness is formed by providing the concavity on the wire mesh surface, not only the constricted portion can be easily bent, but also the concavity is formed in the concavity. By fitting the rod rod, the rod rod can be attached to the side face of the wire mesh without significantly protruding, and a multiple wire mesh excellent in design can be obtained.
