Description

[Detailed explanation of the idea] The present invention relates to improvement of welded wire mesh.

For example, when welded wire mesh is used as a wall core in architecture, construction, etc., or as a retaining material or reinforcing material for concrete, etc., it may be required to have a large thickness or to have no separate front and back sides.

In order to increase the thickness of the wire mesh, it is possible to use irregularly shaped wires to increase the line width in the direction perpendicular to the wire mesh surface, but the load of concrete, etc. that acts on the wires is correspondingly large. Therefore, peeling at the welding point is likely to occur.

This idea was created with these points in mind.
The feature is that by alternately arranging and welding wires perpendicular to the front and back surfaces of one wire, it is possible to easily form a welded wire mesh with a large thickness and no distinction between the front and back sides. It is something.

Hereinafter, embodiments of the present invention will be described in detail based on the drawings.
... are strands arranged at appropriate intervals in the vertical direction, and on the front side and back side of these strands 1, 1, ..., strands 2, 2, .
The wires 1 and 2 are alternately arranged and brought into contact with each other at appropriate intervals so that those on the front side and those on the back side do not overlap, and the intersection portions 3 of both strands 1 and 2 are welded together by electric resistance welding.

The strands 1 and 2 are made of metal wires, and not only those with a circular or square cross section, but also those with other polygonal or irregular shapes can be used. When forming, the vertical and horizontal strands may have the same cross-sectional shape, but
For example, wires 1 in the vertical direction may be round, wires 2 in the horizontal direction may be square, and different cross-sectional shapes and wire diameters may be used in combination. The diameter can also be made different as appropriate.

When welding the intersection 3 of the wires 1 and 2, if the welding area is large, such as when both wires 1 and 2 are in plane contact, the electrical resistance will be small and a large welding current will be required, or the welding Problems such as defects are likely to occur. Therefore, in such a case, the third
As shown in the figure, it is desirable to increase the electrical resistance by providing irregularities such as grooves and protrusions on the welding surface 4 of both or one of the strands.

In this invention, linear strands perpendicular to the front and back sides of linear strands arranged in one direction at appropriate intervals are alternately arranged and abutted, and these strands are crossed. Because it is a welded wire mesh that is integrally welded at the parts, the thickness of the conventional welded wire mesh or crimp wire mesh is only the sum of the diameter or width of each strand, whereas the wire mesh of the present invention The thickness is the sum of the diameter or width of one of the strands, that is, if the diameter or width of each strand is the same, it is 1.5 of the conventional thickness.
It is possible to easily obtain one that is twice as thick and has no separate front and back sides.

In addition, since the present invention has two strands of strands on both the front and back sides of one strand, compared to conventional welded wire meshes, the strands of the present invention are particularly resistant to external forces in the direction of bending the strands. Not only does its strength increase by improving its load-bearing properties, it also improves workability because there is no distinction between the front and back sides, and it is able to bear the load applied to both the front and back sides in a balanced manner. There is an effect that it can be done. Therefore,
When used as a wall core in a building, it is particularly useful because it supports the wall evenly on both sides.

Furthermore, if welding the other strand to the same location on both the front and back sides of one strand, not only will the strength change of the strand at the welding point increase due to penetration, making the quality unstable, but also the number of strands will increase. Although there are drawbacks such as the inability to make the mesh fine, in this invention, the wires on both the front and back sides are welded at positions that do not overlap with each other, so changes in the strength of the wires at the welding point are reduced. The quality of the wire mesh can be stabilized, and at the same time, a welded wire mesh with a large mesh thickness and a small mesh size can be easily formed.
