Reinforced mesh is actually used in many industries. Due to its low cost and convenient construction, it has won everyone's favor during the construction process. But do you know that the steel mesh has a specific use? Today I will talk with you about the little-known things about steel mesh.
Reinforced mesh is mainly used in road bridge deck pavement, old bridge deck renovation, bridge pier crack prevention, etc. The quality inspection of thousands of bridge applications in China shows that the use of reinforced mesh can significantly improve the quality of bridge deck pavement and protect The pass rate of the layer thickness reaches more than 95%, the flatness of the bridge deck is improved, the bridge deck is almost free of cracks, the pavement speed is increased by more than 50%, and the cost of the bridge deck pavement project is reduced by about 10%. Welded mesh or prefabricated steel mesh sheets should be used instead of bundled steel bars. The diameter and interval of steel bars for bridge deck paving should be determined by the bridge structure and load level. It is preferably 6~00mm, the longitudinal and transverse intervals of the steel mesh should be kept equal, and the thickness of the protective layer from the surface of the welded mesh should be less than 20mm.
The steel mesh can quickly reduce the working time of steel bar installation, which is 50%-70% less than manual binding mesh. The steel bar spacing of the steel mesh is relatively close. The longitudinal and transverse steel bars of the steel mesh form a mesh structure and have a firm welding effect, which is conducive to preventing the generation and development of concrete cracks. The pavement, floor and floor are paved with steel mesh. Sheets can reduce cracks in concrete surfaces by about 75%.
The steel mesh can play the role of steel bars, effectively reduce the cracks and depressions in the ground, and is widely used in the hardening of highways and factory workshops. It is mainly suitable for large-area concrete projects. The mesh size of the steel mesh is very regular, which is much larger than the mesh size of the hand-tied mesh. The steel mesh has great rigidity and good elasticity, and the steel bars are not easy to bend, deform and slide when pouring concrete. In this case, the thickness of the concrete protective layer is easy to control and uniform, which greatly improves the construction quality of reinforced concrete.
