  The present invention belongs to the technical field of a rhombus wire mesh used for fence fences, and more specifically, a method for manufacturing a rhombus wire mesh suitable for use as a fence fence body, and a rhombus wire mesh for a fence manufactured by the method described above. It relates to the mounting method.

Conventionally, various structural types of fences using a rhombus wire mesh as a fence body are known and widely practiced. For example, in the past fence illustrated in FIGS. 8 and 9, horizontal rims 11, 11 are installed above and below the columns 12, 12, and the rhombus metal mesh 1, which is a fence body, is formed on the rims 11, 11.

  The past fence illustrated in FIGS. 8 and 9 has a configuration in which the bone wire 19 passed through the upper and lower edges of the rhombus wire mesh 1 is attached to the trunk edge 11 by the hanging metal fitting 20, so that the bolt 21 and the nut 22 of the hanging metal fitting 20 are attached. When the bone line 19 is pushed up by loosening and removing it, a gap through which a person can enter can be opened between the trunk edge 11. If the hanging bracket 20 is attached again after the intrusion, no evidence of intrusion remains.

  In the case of a configuration in which bone wires that are passed through in the horizontal direction at the upper and lower edges and the middle position of the rhombus metal mesh are directly attached and fixed to the support as in Patent Document 1, the workability of the attachment work is considerably improved. However, the bone line is inherently low in rigidity, and when an intruder lifts it forcibly as described above, it is relatively easy to open a gap that allows a person to sink into the ground. poor. In addition, there is a defect that the shape is recoverable and no trace of intrusion is left.

  In the case of the configuration in which the cross section of the rhombus wire mesh is supported through a plate-shaped body edge (flat iron) using the mesh thickness of the rhombus wire mesh as in Patent Document 2 above, the flat iron is used. Is much stronger and rigid than the bone line of the above-mentioned patent document 1, but there is still a limit to the size of the cross-sectional shape of the flat iron that can be passed into it using the mesh thickness of the diamond wire mesh There is. With the above-mentioned flat iron, it is relatively easy to open a gap that allows an intruder to forcibly lift it up to the ground, and the effect of preventing intrusion is not yet perfect.

  As in Patent Document 3, the structure in which the twist knuckles are set up on the upper and lower edges of the rhombus metal mesh is recognized to increase the effect of preventing intrusion. However, twist knuckles are only an auxiliary structure for intrusion prevention fences.

  The object of the present invention is not to use the hanging fence 20 or the bone wire 19 of the past fence illustrated in FIGS. 8 and 9, and toughly using a trunk edge such as a round pipe or a square pipe having a sufficiently large strength and rigidity. It is to provide a method for producing a diamond wire mesh for a fence and a method for attaching the diamond wire mesh for the fence that can be attached with a structure and a structure having a large approach prevention effect with good workability.

As a means for solving the problems of the prior art, a method for producing a rhombus wire mesh for a fence according to the invention of claim 1 is as follows:
For at least one of the upper side or the lower side of the rhombus wire mesh 1 manufactured as an off-the-shelf product, the torsional coupling part 2 in which the ends of the two wire rods a and b arranged in the vertical direction and adjacent in the horizontal direction are coupled together is released. Next, the two wire rods a and b are counted from the end portion (twisted joint portion 2), and the first portion 3 entangled with the adjacent wire rods b and a is unwound and then adjacent to each other. The ends of the two wire rods a and b are twisted again to form the joint 4 and the diamond mesh 7 again, and then the second wire entangled from the end portions of the two wire rods a and b. The rhombus mesh 7 is aligned in a direction substantially perpendicular to the direction of the wire mesh surface by twisting the portion 5 by about 90 degrees in the direction of increasing the degree of entanglement.

The invention described in claim 2 is the method of manufacturing a rhombus wire mesh for a fence described in claim 1,
Twist knuckles 4 ′ are formed when the ends of two wires a and b that are arranged vertically and are adjacent to each other in the horizontal direction are twisted again to form the joint 4 and the rhomboid mesh 7.

A method for attaching a diamond wire mesh for a fence according to the invention described in claim 3 is as follows:
For at least one of the upper side or the lower side of the rhombus wire mesh 1 manufactured as an off-the-shelf product, the torsional coupling part 2 in which the ends of the two wire rods a and b arranged in the vertical direction and adjacent in the horizontal direction are coupled together is released. Next, the portion 3 entangled with the first and second adjacent wires b and a is counted from the end portions (twisted joint portions 2) of the two wires a and b, and then the adjacent portions are adjacent to each other. The ends of the two wire rods a and b are twisted again to form the joint 4 and the diamond mesh 7 again, and then the second wire entangled from the end portions of the two wire rods a and b. Twisting the portion 5 about 90 degrees in a direction to increase its entanglement and aligning the rhombus mesh 7 in a direction substantially perpendicular to the direction of the wire mesh surface;
The trunk edge 11 is passed in common through the rhombus meshes 7 arranged in a direction substantially perpendicular to the direction of the wire mesh surface of the upper or lower side of the fence rhombus metal mesh 1. It is characterized by comprising the steps of mounting and fixing up and down.

According to a fourth aspect of the present invention, there is provided a method for attaching a diamond wire mesh for a fence according to the third aspect,
The trunk edge 11 passing through the rhombus mesh 7 aligned in a direction substantially perpendicular to the direction of the metal mesh surface is a round pipe or a square pipe.

  According to the method for manufacturing a rhombus wire mesh for a fence according to the first and second aspects of the invention, two adjacent wires a, for at least one of the upper side or the lower side of the rhombus wire mesh 1 manufactured as an off-the-shelf product, b is taken as one unit, the twisted joint portion 2 at the end thereof is unraveled, the first entangled portion 3 is counted from the same end portion (twisted joint portion 2), and the two wire rods a and b are again formed. The ends are twisted to form the joints 4 and the rhombus meshes 7, and then twisted by about 90 degrees in a direction to increase the degree of entanglement of the second entangled portion 5 counted from the ends of the two wires a and b. Thus, the rhombus meshes 7 on the upper side or the lower side are efficiently formed in a single-line tunnel shape by a simple procedure and process for aligning the rhombus meshes 7 in a direction substantially perpendicular to the metal mesh surface.

  Therefore, as in the method for attaching a diamond wire mesh for a fence according to the invention described in claims 3 and 4, the size of the rhombus meshes 7... Forming one row passes through the rhombus mesh 7 into a series of tunnel shapes. The construction of the fence can be carried out efficiently with a simple procedure and process in which the trunk edge 11 such as a round pipe or square pipe is commonly passed and the trunk edge 11 is attached and fixed to the support column 12 of the fence.

In particular, by using a trunk edge 11 such as a round pipe or a square pipe having a size substantially inscribed in the inner dimensions of the rhombus mesh 7, a fence having a sufficiently large strength and rigidity can be constructed. Compared with the fence constructed using the bone wire disclosed in Fig. 1 or the flat rim trunk disclosed in Patent Document 2, the intruder lifts the trunk rim 11 and opens a gap with the ground 18. This will contribute to the construction of a fence with a large intrusion prevention effect.
Further, when a square pipe having a size inscribed in the rhombus mesh 7 is used for the trunk edge 11, for example, the rhombus metal mesh 1 is formed into a rectangular shape (see reference numeral 13 in FIG. 5) having the lower trunk edge 11 as a base. In order to cut and invade the square pipe 11, the square pipe 11 is cut as long as both ends of the square pipe 11 are fixed to the column 12 even if the rectangular rhombus wire mesh is pushed inward and outward. Firmly resists the rotation of the diamond-shaped wire mesh. Therefore, even if it can be pushed and deformed so that the hole is forcibly opened, it is difficult to restore the wire net once pushed and bent, and it remains as a trace, leading to early detection of intrusion. Therefore, the effect of preventing intrusion is great.
In addition, when the twist knuckle 4 ′ is formed on the upper side or the lower side of the rhombus metal mesh 1, the effect of the intruder is prevented by the effect of the spines, and the effect of preventing the intrusion is further enhanced.

Next, an embodiment of a method for producing a diamond wire mesh for a fence according to the inventions described in claims 1 and 2 will be described.
FIG. 1 shows the upper side of a rhombus wire mesh 1 manufactured as an off-the-shelf product. The diamond wire mesh 1 uses a steel wire having an exceptional diameter of about 5 mm, and the size of one mesh is usually knitted into a rhombus with a side of about 50 mm. As a knitting method, two wires a and b which are arranged vertically and are adjacent to each other in the horizontal direction are set as a basic unit, and the wires b or a on both the left and right sides are bent to about 90 degrees from each other. And intertwined. And the twist coupling | bond part 2 which twisted together the edge parts of the two wire materials a and b is formed in the upper side part (and lower side part).

  The first step of the manufacturing method according to the present invention starts with twisting back the twisted joint portion 2 joined by twisting the end portions as described above and releasing it as shown in FIG. Next, the two wire rods a and b, which are formed as the torsion coupling portion 2, are counted from the upper end portion of FIG. 2 is set to the release state.

Thereafter, the ends of the two adjacent wire rods a and b are twisted again to form the coupling portion 4, and the rhombus mesh 7 in which the entanglement with the adjacent wire rod is separated and independent as shown in FIG. 3 is formed. To do. Thereafter, the two wire rods a and b are twisted about 90 degrees in the direction of increasing the degree of entanglement around the second entangled part 5 counted from the twisted coupling part 2 in FIG. The meshes 7 are aligned in a direction substantially perpendicular to the direction of the metal mesh surface (see FIG. 4).
As a result, as shown in FIGS. 6A and 6B, rhombic meshes 7 formed in a row in the direction of the wire mesh surface are formed in a series of tunnel shapes. In addition, although the illustration of the wire mesh making machine is omitted in the above, naturally, all the processes are automatically and continuously performed in the process of manufacturing a so-called rhombus wire mesh using the wire mesh making machine. To implement.

As in the invention described in claims 3 and 4, the body of the rhombus mesh 7 aligned in a direction substantially perpendicular to the direction of the wire mesh surface of the upper side or / and the lower side of the rhombus wire mesh 1 for the fence. The intrusion prevention fence shown in FIG. 5 is easily and efficiently constructed with a small number of steps by passing the edge 11 in common and attaching and fixing the trunk edge 11 to the top and bottom of the columns 12 and 12 as shown in FIG. be able to. Reference numeral 19 in FIG. 5 indicates a bone line.
The trunk edge 11 may be either a round pipe or a square pipe having high strength and rigidity as long as it can be passed through the rhombus mesh 7 aligned in a direction substantially perpendicular to the direction of the wire mesh surface. It can be used and contributes to the construction of a solid fence for preventing intrusion (the invention according to claim 4).

  However, if a square pipe having a size substantially inscribed in the internal dimensions of the rhombus mesh 7 is used as the trunk edge 11 as shown in FIG. 6B, for example, as shown by the dotted line 13 in FIG. Even if the rhombus metal mesh 1 is cut into a rectangular shape with each pipe 11) as the base and the cut rectangular rhombus metal mesh portion is pushed inward and outward, both ends of the square pipe 11 are firmly attached to the columns 12, 12. As long as it is fixed, the square pipe 11 strongly resists the rotation of the cut rhombus wire mesh portion, so that the effect of preventing intrusion is great. If it is pushed and deformed enough to open a hole that allows people to pass by force, it is impossible to restore it to its original shape again after intrusion, so it can be discovered early with so-called traces, which also prevents intrusion The effect is great.

  Incidentally, as shown in FIG. 7, as an example, the trunk edge 11 passing through the rhombus meshes 7... Aligned in the direction substantially perpendicular to the direction of the metal mesh surface as shown in FIG. A bolt 14 having a bracket 16 composed of a pair of sandwiching brackets 16a and 16b sandwiching both side surfaces of the bolt is passed through a bolt hole 15 previously provided in the column 12 from the outside to the inside, and is fastened to the column 12 with a nut 17. In addition, it can be firmly attached and fixed. According to the structure of FIG. 7, the nut 17 is located inside the rhombus metal mesh 1 and cannot be reached from the outside, which is extremely effective for preventing intrusion.

  In addition, as explained in the paragraph number [0019] above, as a process of the manufacturing method of the rhombus wire mesh, in the step of twisting the ends of the two adjacent wire rods a and b again to form the coupling portion 4, Can be formed into a twisted knuckle 4 that is divided into two branches like thorns (the invention according to claim 2). In this way, as clearly shown in FIG. 6, the gap with the ground 18 is blocked to prevent the invasion of small animals such as weasels, mice, moths and moths, and the effects of the thorns prevent clues to the intruder, The effect of preventing intrusion is further enhanced.
