Technical requirements for welded reinforcing mesh

One of the main requirements for reinforcing mesh is their strength. The strength of the mesh depends on its design: what smaller size cells, the stronger the mesh, and the higher its ability to withstand heavy loads. You can check the quality of the mesh by its weight: the larger it is, the greater the load the mesh can withstand. To do this, weigh the roll of masonry mesh and calculate the weight of 1 square meter. m. and compare with the theoretical (reference) weight. If the difference in weight is more than 5%, then you should check other parameters of this roll.

Other specifications product. Depending on the height, our mesh panels are made with 2-4 times the reinforcement, each 100mm wide for even greater rigidity. For simplicity. Stiffer mesh is more stable than flexible mesh. The color evaporates and plasticizes, providing high resistance to wear and corrosion to keep the color intact for many years.

lightweight - have transverse and longitudinal rods from 3 to 10 mm;
heavy - rods located in one direction and having a diameter of 12 mm.

Another subgroup, which is determined by the direction of the reinforcement:

working fittings located in one direction (transverse or longitudinal), and distribution fittings in the other;
working fittings are located in both directions.

1.1 Characteristics

Reinforcing mesh according to GOST 23279-2012 (85) has the following types:

This tool weighs approximately 8 kg and must be connected to a source of compressed air. Bar 2 or 3 m long, equipped with 2 handles and numerous hooks that snap into the grids of vertical electric welded panels. Temporarily tightens the gabion during filling.

Mesh mesh side edge and edging with double twist hexagonal mesh

Wires are larger in diameter than wire mesh and reinforce the twisting of the mesh. The bracket is parallel to the wires and is woven simultaneously with the wire mesh. After weaving, a side border is added perpendicular to the mesh. A metal structure in plumbing was used to temporarily close double torsion box gabions while they were being filled.

type 1 (heavy) - the diameter of the working fittings is larger than that of the distribution fittings;
type 2 (heavy) - there is working reinforcement in both directions;
type 3 (heavy) - the working fittings are located in the transverse direction and their diameter is larger than that of the distribution fittings;
type 4 (light) - transverse rods are located across the entire width of the mesh;
type 5 (light) - has offset transverse rods.

Meshes are produced in accordance with GOST 23279-2012 (85), in flat or roll form.

Rectangular parallelepipedal rectangular structure made of electroscrub mesh or hexagonal double torsion mesh in various sizes. A gabion cage is usually divided evenly into inner cells by one or more diaphragms. Gabion boxes, gabion soles, mattress gabions and multi-cell gabions are available.

Vertical gabion walls. There is front and back view and both ends. Top part closes the gabion. The cover may be part of the structure or may be separate. Dark brown rust, Dark brown rust. Definition of hexagonal mesh type as a function of cell size.

2 Options

The pitch of the rods in the same direction is the distance between them and it should be the same over the entire area. For heavy meshes of the first type, it is allowed to have an additional step of transverse rods at the edge of the product, which can be equal to 100, 200 and 300 mm.

A rectangular panel of electro-welded wire mesh or twin-screw hexagonal mesh used to evenly divide a gabion cage into internal cells. The nominal mesh size is the axle-to-axle distance between two successive wires for electric welded panels and between the torsion axis for woven gabions with hexagonal meshes. In the case of woven gabions with a two-turn hexagonal mesh, the mesh size is an average distance of more than 10 meshes, measured at right angles between the twisted sides of the mesh.

Lightweight reinforcing mesh can have an additional step in the longitudinal direction at the edges or cutting points (cutting is carried out using special scissors, which can be read about separately). The additional pitch of the rods located longitudinally can have dimensions from 50 mm to a given cell size (50 × 50, 100 × 100 mm), while at the edge it should be a multiple of 10 mm, and in places of cutting 50 mm.
The second indicator is indicative. A hexagonal-shaped mesh formed by twisting two or two adjacent threads alternately to the right and then to the left. A type of woven mesh in which the wires are twisted together. Spiral winding of two wires around each other at an angle of rotation of the two wires of 180°. The wires only rotate in one direction. Visually, some people think there are three swirls.

The resulting sheet is stopped at each edge by a border consisting of a wire with a diameter larger than the diameter of the wire used for the entire screen. Method for manufacturing gabion panels. We are talking about welded mesh or electric welded panels. The wires or rods are connected by spot welding. This production method allows the use of very small and large wires, which allows the panels to be very stable and more rigid. The grids are square or rectangular and can vary from one side of the panel to the other.

The transverse components of the reinforcing mesh can have an additional step from 50 to 250 mm, with a multiplicity of 10 (50×50, 100×100 mm).

Lightweight reinforcement made in one strip, may be with release of longitudinal rods from 25 to 250 mm (multiples of 5). For transverse values, values of 15, 20 and 30 mm, or from 25 to 100 mm (with a multiple of 25) are allowed. Such outlets are suitable for cells with dimensions of 50×50, 100×100, 100×250 mm.
Larger diameter wire used to outline the mesh, perpendicular to the production direction and double twisted, by mechanically winding the mesh wires with at least 2.5 windings around each mesh. Steel wire coated with zinc, zinc-aluminum alloy or organic coat or stainless steel wire and used to assemble and join empty gabions and to close and join adjacent gabion cages in a structure, replacing spirals or staples.

Ligature wire can also be used as ties to prevent cladding from deforming. Metal wire used for bordering toast sheets, in the direction of the mesh production and parallel to the double twist, by continuously weaving the mesh.

2.1 Dimensions

These parameters are presented in the following form: 50x50x4, 100x100x5. From the numbers you can determine that the cell is a square, the sides of which are 5 (10) cm, and the diameter of the rod is 4 (5) mm, according to the examples above.

2.3 Technical requirements

Welded metal mesh from reinforcing steel is manufactured in accordance with GOST 23279-2012 (85) and specific working drawings, as well as accompanying technological documentation.

Working reinforcement in heavy meshes is made of class A-III steel with a rod cross-section of 10-40 mm. In some cases, the use of steel is allowed A-I diameter 10-32 mm.

Heavy mesh distribution fittings (type 1) are made from steel A-I II (6-16 mm), and in type 3 - steel A-III (10-16 mm) and steel A-I (6-16 mm).

For light meshes, steel class B500C (4-5 mm), reinforcing wire made from steel class BP-1 (3-5 mm) and reinforcement made from steel grades A-III and A-I (6-10 mm) are used.

Distribution fittings can be steel B500S with a diameter of 4-5 mm and wire B-l diameter 3-5 mm.

The connection of the rods at their intersections is carried out using resistance spot welding, the operating modes of which must comply with regulatory documents.

In products made using steel grades A-I, V mandatory, all intersections of the rods must be fastened. When assembling a product from rods and wires, connection of intersections by welding is allowed through one or two in a checkerboard pattern. In this case, the two rods running along the edges of the product must be fastened without fail.

A maximum of two non-welded intersections (using clamps) per area of 1 m² is allowed out of the required number of connections.
