Description

[Detailed Description of the Invention] The present invention relates to a welded wire mesh for reinforcing concrete, which is used as a core material for concrete roads, floors of concrete buildings, etc.

Conventional reinforcing wire mesh of this type uses wire rods with a circular cross section as reinforcing bars that are combined vertically and horizontally, so it lacks overall strength and has the disadvantage of causing cracks in the concrete.

In order to eliminate these drawbacks, the present invention uses a vertically elongated cross-section wire as the vertical wire to be combined with the horizontal wire to increase the overall strength and increase the strength of the welded joints with the horizontal wire. It provides welded wire mesh.

To explain the embodiment of the present invention based on the attached drawings, 1 is a vertical wire material made of a straight iron wire having a vertically long rectangular cross section of 6.5 mm in height x 5.5 mm in width. A plurality of horizontal wire rods 2 having a circular cross section of 6 mm in diameter and a rough surface on the upper surface side of the vertical wire rod 1 are arranged in parallel at appropriate intervals and combined, and both wire rods 1, 2 are arranged in parallel at appropriate intervals. A frame-shaped welded wire mesh A is formed by welding 3 the intersections of the wires by multipolar electric welding.

Note that the horizontal wire 2 is not limited to a circular cross section;
A deformed wire may also be used.

This welded wire mesh A is used to reinforce a road, for example, by laying the vertical wire rods 1 in the longitudinal direction of the road, and then concrete is poured to construct the road.
Alternatively, it is assembled at the construction site of a building, etc., and concrete is poured to construct the walls, etc. of the structure.

As described above, in the present invention, a plurality of vertical wire rods 1 and a plurality of horizontal wire rods 2 made of straight iron wire are welded 3 at appropriate intervals to form a frame shape. Since this is a welded wire mesh for reinforcing concrete with vertically long steel wires, the vertical wires of the reinforcing bars are steel wires with a vertically long cross section, which increases the strength of the entire reinforcing bars and increases the durability of concrete structures. It is possible to
Moreover, since the joint area between the vertical wire and the horizontal wire is large, the welding strength between the two is increased, and the bending strength is further increased, thereby preventing cracks in the concrete.
