Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is applicable to small sloping land (for example, 1
~ 8 degrees) relates to a method of manufacturing a lattice wire mesh for fences.

[0002]

2. Description of the Related Art Among conventional grid wire nets having a girth composed of a plurality of horizontal and vertical wire rods, one for a sloping ground is shown in FIGS. 7A to 7D even when the angle of the sloping ground is as small as 8 degrees or less. It was manufactured in the same process.

First, as shown in FIG. 7-A, the wire mesh main body corresponding portion J
In the state where there is no horizontal wire rod, that is, the wire mesh main body equivalent portion J1 is the vertical wire rod 21 only, and the furthest edge portion K1 at the upper and lower ends thereof is the state in which the horizontal wire rod 22 is welded to the vertical wire rod 21, As shown in Fig. B, the furring strip equivalent portion K1 is bent into a cylindrical shape to form a furring strip K, and then only the furring strip K is slanted so as to match the slope of the sloping ground as shown in Fig. C. After that, as shown in FIG. 7D, the horizontal wire 24 was welded to the portion corresponding to the wire mesh body in an inclined state to form the wire mesh body J.

[0004]

However, in the manufacturing method of the grid wire mesh for the slanted ground fence described above, the welding process of the vertical wire and the horizontal wire requires two steps as shown in FIGS. 7A and 7D, and As in C, a step of inclining only the furring strip K to match the inclination of the sloping ground is also required, and there is a problem that it is expensive and low in efficiency.

The present invention requires only a single electric welding process for vertical wire rods and horizontal wire rods, and does not require a process for sloping only the furring strip to match the slope of a sloping ground. The purpose of the method is to provide a method for manufacturing a lattice wire mesh.

[0006]

As shown in FIG. 1A, a plurality of horizontal wire rods 1a are arranged in parallel with each other at a constant large interval C in a wire mesh main body corresponding portion A1 to form a furring strip. In the corresponding portion B1, a plurality of horizontal wire rods 1b are arranged in parallel to each other at a constant small interval D, and in the horizontal wire rods 1a and 1b, a plurality of vertical wire rods 2 are arranged in parallel to each other at a constant interval E. The angle Z formed by the vertical wire rods 1a and 1b is set to an angle obtained by subtracting a predetermined small slope ground angle Y from 90 degrees, and the horizontal wire rods 1a and 1b and the vertical wire rods 2 are electrically welded in the same process, As shown in FIG. 9B, the furring strip equivalent portion B1 is bent into a lattice cylinder shape to form a furring strip B, and the other is a wire mesh main body A.

[0007]

[Operation] According to the above manufacturing method, the electric welding process of the vertical wire and the horizontal wire is only one process, and the process of inclining only the furring to match the inclination of the sloping ground can be eliminated.

[0008]

Embodiments of the present invention will be described below with reference to the drawings.
First, the first embodiment will be described with reference to FIGS. 1 and 2. In the method of manufacturing the lattice wire mesh, as shown in FIG. 1A, a plurality of horizontal wires 1a (for example, wire diameter 3 to 5 mm) )
Are arranged parallel to each other on the jig at a constant large interval C. Next, the furring strip equivalent portion B that is the upper and lower ends (or only the upper end)
1, a plurality of horizontal wire rods 1b are arranged in parallel with each other on the jig at a constant small interval D, and a plurality of vertical wire rods 2 (for example, a wire diameter of 3 to 5 mm) are spaced at regular intervals with respect to the horizontal wire rods 1a and 1b. At E, they are arranged on the jig in parallel with each other.

At this time, the angle Z formed by the horizontal wires 1a and 1b and the vertical wire 2 is from 90 degrees to a predetermined small slope ground angle Y.
(For example, 1 to 8 degrees) is set to an angle that is subtracted, and the horizontal wire rods 1a and 1b and the vertical wire rod 2 are electrically welded in the same step.

Next, as shown in FIG. 1B, the upper and lower end portions corresponding to the furring strip B1 are formed in a lattice cylindrical shape (for example, the outer diameter F is 50 to 6).
This is a manufacturing method in which the furring strip B is bent to 0 mm) and the wire mesh main body A is formed with the others. At this time, as shown in FIG. 2, the vertical wire 2 of the furring strip B is slightly spiral.

Next, referring to FIGS. 3 and 4, a method of constructing a fence using a grid wire net for small-sloping ground will be described. First, a plurality of columns 3 are erected vertically on a small-sloping ground at a predetermined interval from each other. Bolt one end 4a of the joint 4 to the pillar 3
Fix with the nut 5, and then the tubular portion 4 which is the other end of the joint 4.
b is fitted in the furring strip B of the lattice wire mesh, and a washer 6 having a pair of seat plates 6a is applied to the B outer side of the furring strip.
The seat plate 6a, the furring strip B, and the tubular portion 4b of the joint 4 are fastened with bolts and nuts 7 different from the above.

Most of the projecting portion 8 at the end of the furring strip (the portion projecting from the endmost vertical wire 2 of the wire mesh main body A) is hidden by the joint 4 from the front direction, so that the appearance does not deteriorate remarkably. . However, when the outer peripheral diameter F of the furring strip B (or the deployment length W1 of the furring strip) is large, the projecting amount W2 of the projecting portion 8 also becomes large, and there is a problem in mounting the joint, so the small tilt angle is 8 degrees. Is the limit, and less than once,
Horizontal grid mesh is available.

Further, in the above embodiment, the furring strip B has a lattice cylinder shape, but the present invention is not limited to this shape,
For example, as shown in FIG.
As shown in FIG. 5B, a lattice rhomboid cylinder may be used.
As shown in FIG. 5D, it may be a lattice pentagonal cylinder, a lattice hexagonal cylinder, or a lattice ellipse cylinder.

Further, as shown in FIG. 5E, the furring strip B may have a lattice open frame shape having a substantially U-shaped cross section, and as shown in FIG. 5F, it may have a lattice open frame shape having a substantially V-shaped cross section. . In addition,
When the developed length of the furring strip B is small as in this example, the small inclination angle is limited to about 15 degrees.

Further, in the present invention, as in the second embodiment of FIGS. 6A and 6B, the horizontal wire rods 1a and 1b and the vertical wire rods 2 are not limited to straight lines, but may be straight lines including the deformed portions 1c and 2a. It may exist or may be a curve. Other configurations and operations are similar to those of the first embodiment.

That is, the present invention is not limited to the above embodiments, and it goes without saying that many modifications and changes can be made to the above embodiments within the scope of the present invention.

A plurality of vertical wire rods are arranged in parallel with each other at intervals, and a plurality of vertical wire rods are arranged in parallel with each other at a constant interval with respect to the horizontal wire rods, and the angle formed by the horizontal wire rods and the vertical wire rods is 90 ° minus a predetermined small ground angle. Set to different angles, the horizontal wire and vertical wire are electrowelded in the same process, and then the furring strip equivalent part is bent to form a lattice cylinder or open lattice frame to form a furring strip, and the others are the wire mesh body.
