Abstract

PROBLEM TO BE SOLVED: To provide a lattice metal net having a deformation freedom capable of conforming with not only a flat area but also a slanted area with ease. SOLUTION: A metal net connector is provided with two independent clamping areas 34 respectively. The bottoms of these clamping areas 34 are piercingly coupled with a pin where the clamping area 34, which are not interfered with each other, are arranged to be turnable freely. They are connected with the connector so that they may turn their points of intersection between a vertical line and a horizontal line intersecting with each other. The angle which intersects the vertical line with the horizontal line is adapted to be changed freely, thereby providing a lattice metal net having a deformation freedom.

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a technique of a lattice wire mesh formed by intersecting a vertical line and a horizontal line. Related to the provision of the lattice wire mesh.

[0002]

2. Description of the Related Art Conventionally, general lattice fences and mesh fences are as shown in FIG. That is, the vertical line 1 and the horizontal line 2 are intersected in an orthogonal state, and the intersections of these lines are welded.

[0003]

According to the wire mesh by the above-mentioned conventional welding connection, there is a limit to the capacity of the automatic welding machine, and therefore, the width of about 2 m can be manufactured. there were. Therefore, in practical use, the above 2
In many cases, unit wire meshes of about m width had to be spliced together by connecting metal fittings or welding, and the seams of the wire meshes became unsightly.

In some cases, the fence is attached along a sloped ground. At this time, since the angle at which the vertical line and the horizontal line intersect cannot be freely changed in accordance with the inclination with the wire mesh formed by welding, the fence is stretched diagonally. In the part, it is necessary to separately make the tilt-dedicated wire netting NF2 as shown in FIG. 5 according to the tilt, which is troublesome and expensive. In addition, NF1 shows the grid wire net for level ground, Gr1 shows a flat ground, and Gr2 shows a slope ground.

Therefore, the problem to be solved by the present invention is to provide a connecting metal fitting for a grid wire mesh and a grid wire mesh using the metal fitting, which has a degree of freedom of deformation that can be easily applied not only to flat ground but also to sloping ground. Especially.

[0006]

The metal mesh connecting fitting provided by the present invention has two independent wire rod gripping portions, and the bottom surfaces of these gripping portions are pin-connected to each other so that the gripping portions do not interfere with each other. It can be freely rotated.

Further, the lattice wire net provided by the present invention is
By using the above-mentioned connecting metal fittings, the intersecting points of the vertical and horizontal lines of the intersecting wire mesh can be rotated so that the angle at which the vertical and horizontal lines intersect can be freely changed. is there.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS FIG. 1 shows a concrete example of a metal mesh connecting fitting according to the present invention. That is, in the connecting fitting of this specific example, the holding members 3 and 4 of the U-shaped channel are made to face each other with their back walls facing each other, and one pin 5 is pierced and penetrated at the center of the facing portions thereof. Each of the gripping members 3 and 4 rotates independently about the pin 5 as a rotation axis and can change direction.

FIG. 2 shows another specific example of the metal mesh connecting fitting according to the present invention. That is, in the connecting fitting of this specific example, the gripping members 3'and 4'having a substantially C-shaped channel are made to have their one side edges back-to-back, and the back-to-back connecting portion 1
The pin 5'of the book is skewered and penetrated so that each of the gripping members 3'and 4'can independently rotate and change direction with the pin 5'as a rotation axis.

FIG. 3 shows a wire mesh connecting portion using the wire mesh connecting metal fitting of the above-mentioned specific example. The vertical line 1 of the wire mesh is made to hold one gripping member 3 (3 '), and the horizontal wire 2 of the wire mesh is made to grip the other gripping member 4 (4').
Thus, the angle at which the vertical line 1 and the horizontal line 2 intersect can be freely changed by the independent rotation of the gripping members 3 (3 ') and 4 (4').

According to the lattice wire net cross-coupled by such a unique metal net connecting metal fitting, the wire net NF1 for flat ground as shown in FIG. It is also possible to configure the wire mesh NF2 for inclined ground by changing the crossing angle of the vertical line and the horizontal line of the wire mesh. Therefore, according to the grid wire net of the present specific example, it is not necessary to manufacture a special wire net for sloping ground, and the grid wire net can be generally applied to terrain with rich undulations.

[0012]

According to the present invention as described above, there is a degree of freedom of deformation that can be applied to not only flat ground but also sloping ground.
It is possible to achieve the intended object of providing a connecting metal fitting for a grid wire mesh and a grid wire mesh using the fitting. In addition, since it is possible to apply the flat wire mesh as it is to angled places such as sloping ground and side surfaces of stairs, there is no need to hand-make a special wire mesh that matches the angle, thus reducing the total cost. Can contribute to.
