Description

  The present invention relates to a diamond-shaped wire mesh, and more particularly to a composite diamond-shaped wire mesh in which a plurality of mesh portions different in mesh pitch are integrally formed.

The rhombic wire mesh is a wire mesh in which parallelograms are continuously formed by interlacing wires processed into a corrugated shape.
The rhombus wire mesh is advantageous in that it has high impact absorbing power because the junction points of the mesh are not fixed, and it can be easily transported because it can be folded, and partial repair is possible by replacing the wire. Are widely used in various applications to provide various functions.

"JIS G3552 rhombus wire mesh" (Japanese Industrial Standard: 2007)

Depending on the application, different mesh pitches may be required in a single wire mesh.
For example, in the technical field of the beast net, the mesh pitch at the bottom of the wire mesh needs to be smaller than the mesh pitch at the top in order to prevent small animals from invading.
However, it is technically very difficult to manufacture a wire mesh in which two or more types of mesh pitches are combined together.
A method is also conceivable in which wire meshes having different mesh pitches are connected via a connecting coil or a wire, but this impairs the structural integrity, so that the shock absorbing ability of the wire mesh is significantly reduced.
Therefore, in the field of wire mesh technology, "small size is large", that is, a wire mesh with a small mesh pitch has the function of a large wire mesh, but the reverse is not the characteristic that the area requiring a small mesh pitch is small. However, the entire wire mesh must be manufactured with a wire mesh with a small mesh pitch.
For this reason, in addition to the increase in material cost, the weight of the entire wire mesh increases, which affects the design of the structure and degrades the construction efficiency.

  An object of the present invention is to provide a composite rhombus wire mesh that can solve the above problems.

The composite rhombus wire mesh of the present invention comprises at least a first mesh portion and a second mesh portion adjacent to the Y direction of the first mesh portion, and is characterized in that the first pitch is larger than the second pitch.
According to this configuration, it is possible to provide a composite rhombus wire mesh in which a plurality of mesh portions different in mesh pitch are integrally formed.

In the composite diamond mesh of the present invention, the first pitch may be an integral multiple of 2 times or more of the second pitch.
According to this configuration, it is possible to engage all the first projecting portions in the connecting portion with the second projecting portion to firmly connect the both.

In the composite rhombus wire mesh of the present invention, the line diameters of the first mesh portion and the second mesh portion may be equal.
According to this configuration, the mesh portions can be connected without losing the integrity of the structure.

In the composite rhombic wire mesh of the present invention, the inner angle of the first protrusion may be the same as the inner angle of the second protrusion.
According to this configuration, it is possible to transmit the tensile stress, and it is possible to improve the shock absorbing ability of the entire wire mesh.

In the composite diamond mesh of the present invention, the thickness of the first mesh may be the same as the thickness of the second mesh.
According to this configuration, since no gap is generated in the engaging portion between the projecting portions, the integrity of the wire mesh can be enhanced.

The composite rhombus wire mesh of the present invention may connect the first mesh portion and the second mesh portion alternately.
According to this configuration, a refined design can be configured by a combination of mesh pitches and used for interiors and the like.

The composite rhombic wire mesh of the present invention can provide an integrated structure composed of wire meshes different in mesh pitch, and therefore has at least one of the following effects.
Since it is possible to reduce only the mesh pitch of the necessary part of the <1> wire mesh, the material cost can be significantly reduced.
The weight of the wire mesh can be significantly reduced because only the mesh pitch of the necessary part of the wire mesh can be reduced.
By making the wire diameter, the internal angle, the thickness, etc. other than the <3> mesh pitch the same, it is possible to connect a plurality of mesh portions without losing the integrity of the structure.
<4> It is easy to connect the mesh section and can be assembled on site.
High aesthetics can be created by combining different mesh pitches with the same wire diameter and internal angle.
A refined design can be expressed by repeating different mesh pitches.

Hereinafter, the composite rhombic wire mesh of the present invention will be described in detail with reference to the drawings.
The composite rhombic wire mesh of the present invention is a structure of a single wire mesh, and its structure and effect are completely different from the connection structure of face members such as the connection portion between the wire mesh panels constituting a futon.
In the present specification and the like, the “X direction” is the continuous direction of the row lines, that is, the width direction of the rhombus wire mesh. The “Y direction” is a direction orthogonal to the X direction, that is, the length direction of the rhombus wire mesh. The "pitch" of a mesh means the distance between adjacent meshes.

[Combination diamond mesh]
<1> Overall configuration (FIG. 1).
The composite rhombus wire mesh 1 of the present invention is a rhombus wire mesh in which two or more types of mesh portions having different mesh pitches are integrally combined.
The composite rhombus wire mesh 1 at least includes a first mesh portion 10 and a second mesh portion 20.
The first mesh portion 10 and the second mesh portion 20 are integrally connected at the connection portion J in the Y direction.
In this example, an example in which the first mesh portion 10 is combined with the upper portion and the second mesh portion 20 smaller in mesh pitch than the first mesh portion 10 is combined with the lower portion will be described.
The combination of the composite rhombus wire mesh 1 is not limited to this, and the mesh pitch of the upper first mesh portion 10 may be smaller than the mesh pitch of the lower second mesh portion 20 according to the application.
Alternatively, the mesh pitch may be repeatedly changed every one row or several rows (FIG. 2). In this case, a sophisticated design can be configured by a combination of mesh pitches, and can also be used for interiors such as mesh art.
Moreover, a mesh part may combine not only two types but three types or more.

<2> First Net Department.
The first mesh portion 10 is formed by connecting a plurality of wave-shaped first row lines 11 continuous in the X direction in the Y direction via first projecting portions 11 a protruding in the Y direction.
The first mesh portion 10 has a first mesh size S1, a first pitch P1, and a first angle θ1 of the first protrusion 11a (FIG. 3).
The plurality of first row wires 11 are formed by spirally winding the wire in the same direction by a diamond wire mesh manufacturing apparatus.
In this example, a galvanized wire mesh having a wire diameter of 4 mm and a mesh size of 50 mm is employed as the first mesh portion 10.

<3> second net department.
The second mesh portion 20 is formed by connecting a plurality of wave-like second column lines 21 continuous in the X direction in the Y direction via the second protrusions 21 a protruding in the Y direction.
In this example, the diameter of the second row line 21 is the same as the diameter of the first row line 11.
Further, in the present embodiment, the thickness of the second mesh portion 20 is made equal to the thickness of the first mesh portion 10.
The second mesh portion 20 has a second mesh dimension S2, a second pitch P2, and a second angle θ2 of the second protrusion 21a (FIG. 3).
In this example, a galvanized wire mesh having a wire diameter of 4 mm and a mesh size of 25 mm is employed as the second mesh portion 20.
In addition, the wire diameter and mesh of the 1st mesh part 10 and the 2nd mesh part 20 mentioned above are only an illustration, and as long as the fixed relationship mentioned later is satisfy | filled, another combination may be sufficient.

<4> connection part (FIG. 3).
The first mesh portion 10 and the second mesh portion 20 are first projecting portions at the lowermost first row line 11 of the first mesh portion 10 and the uppermost second row line 21 of the second mesh portion 20. It connects with 11a via the 2nd projection part 21a.
The composite rhombic wire mesh 1 of the present invention can be easily integrated with each other only by screwing one row line between the first mesh portion 10 and the second mesh portion 20 in the X direction. For this reason, it is possible to easily assemble the integrated diamond-shaped wire mesh 1 not only at the factory but also at the site.
In addition, since the wire diameter and thickness of the first row wire 11 and the second row wire 21 are the same, no gap is generated in the engaging portion between the projecting portions, and wire mesh having different mesh pitch while securing the integrity of the wire mesh It can be combined.

Relationship of <5> pitch etc. (FIG. 3).
A first pitch P1, which is a distance between adjacent first protrusions 11a, is larger than a second pitch P2, which is a distance between adjacent second protrusions 21a.
Desirably, the first pitch P1 is set to be an integral multiple of twice or more of the second pitch P2, for example, two or three (FIG. 4). By this, all the 1st projection parts 11a in connecting part J become engageable with the 2nd projection part 21a, and can connect the 1st net part 10 and the 2nd net part 20 firmly.
However, the present invention is not limited to integral multiples. For example, when the first pitch P1 is set to 1.5 times the second pitch P2, the first projecting portion 11a will be engaged with the second projecting portion 21a at a first fly.
Further, in this example, a first angle θ1 which is an inner angle of the first protrusion 11a is set to be equal to a second angle θ2 which is an inner angle of the second protrusion 21a.
As a result, since the mesh of the first row wire 11 and the mesh of the second row wire 21 are linearly connected in the oblique direction, it is advantageous for the transmission of tensile stress between the first mesh portion 10 and the second mesh portion 20. The shock absorbing ability of the entire composite rhombus wire mesh 1 is improved.
Moreover, since it becomes a twill weave-like mesh | network arrangement, the whole beauty appearance increases.

[Example in which the internal angle of the protrusion is different]
In the composite rhombus metal mesh 1 of the present invention, the first angle θ1 and the second angle θ2 may be different as long as the first pitch P1 and the second pitch P2 secure a predetermined proportional relationship.
In this case, it is possible to combine wire meshes different in internal angle depending on the application of the composite diamond wire mesh 1.

[Examples with different wire diameters]
In the composite rhombus wire mesh 1 of the present invention, the diameter of the first row line 11 and the second row line 21 may be different as long as the first pitch P1 and the second pitch P2 secure a predetermined proportional relationship. . In this case, wire meshes different in wire diameter can be combined according to the application of the composite rhombus wire mesh 1.
For example, in mesh art, various designs can be expressed by a combination of mesh pitch and wire diameter.
