News - Do you know about Reinforcing Mesh?

Reinforcing mesh is also called: welded steel mesh, steel welded mesh and so on. It is a mesh in which longitudinal steel bars and transverse steel bars are arranged at a certain interval and are at right angles to each other, and all intersections are welded together.

Feature

1. Special, good earthquake resistance and crack resistance. The mesh structure formed by the longitudinal bars and transverse bars of the reinforcing mesh is firmly welded. The bonding and anchoring with the concrete is good, and the force is evenly transmitted and distributed.
2. The use of reinforcing mesh in construction can save the number of steel bars. According to actual engineering experience, the use of reinforcing mesh can save 30% of the steel bar consumption, and the mesh is uniform, the wire diameter is accurate, and the mesh is flat. After the reinforcing mesh arrives at the construction site, it can be used directly without processing or loss.
3. The use of reinforcing mesh can greatly speed up the construction progress and shorten the construction period. After the reinforcing mesh is laid according to the requirements, the concrete can be poured directly, eliminating the need for on-site cutting, placing, and binding one by one, which helps to save 50%-70% of the time.

Application

1. Application of reinforcing mesh in highway cement concrete pavement engineering

The minimum diameter and maximum spacing of reinforcing mesh for reinforced concrete pavement shall comply with current industry standards. When cold-rolled ribbed steel bars are used, the steel bar diameter shall not be less than 8mm, the longitudinal steel bar spacing shall not be greater than 200mm, and the transverse steel bar spacing shall not be greater than 300mm. The vertical and horizontal steel bars of the welded mesh should have the same diameter, and the thickness of the protective layer of the steel bars should not be less than 50mm. The welded mesh for reinforced concrete pavement reinforcement can be implemented in accordance with the relevant regulations for welded mesh for reinforced concrete pavement.

2. Application of reinforcing mesh in bridge engineering

Mainly used in bridge deck pavement of municipal bridges and highway bridges, renovation of old bridge decks, anti-cracking of bridge piers, etc. The quality acceptance of thousands of bridge applications in China shows that the use of welded mesh can significantly improve the quality of the pavement layer of the bridge deck, the pass rate of the thickness of the protective layer is over 97%, the flatness of the bridge deck is improved, the bridge deck is almost free of cracks, and the pavement speed is increased More than 50%, reducing the cost of bridge deck pavement by about 10%.

3. Application of reinforcing mesh in tunnel lining

According to national regulations, the ribbed reinforcing mesh should be installed in shotcrete, which is conducive to improving the shear and bending strength of shotcrete, improving the punching resistance and bending resistance of concrete, improving the integrity of shotcrete, and reducing the risk of shotcrete.
