Welded wire mesh is factory produced. The size of the grid space and the number of steel bars are accurate. This method overcomes the problems caused by traditional manual binding methods due to large dimensional errors, poor binding quality, and missing buckles. The mesh size of welded mesh is very regular, far more than that of hand-bound mesh.
The welded mesh has high stiffness and good elasticity. Rebar does not bend easily and does not change when concrete is poured. The thickness of the concrete protective layer is uniform and easy to control, which significantly improves the quality of the steel bars. Due to the use of vertical and horizontal steel spot welding into a network structure to achieve the common purpose of uniform pressure, the deformation of the cross-rib steel bar section and the strengthening of the clamping force of the concrete structure improve the performance of the concrete structure, effectively preventing the occurrence of concrete cracks and improving concrete structures. Internal quality of reinforced concrete.
Test analysis shows that when laying welded mesh channels on concrete pavement, it can effectively reduce concrete surface cracking caused by load or humidity by about 70%. For concrete bent plate components, welded webs can increase the stiffness of the plate by about 50%. Improves crack resistance by about 30% and effectively reduces crack width by about 50%.
Since welded wire mesh is a continuous production method, it can minimize losses during steel processing. According to statistics, after deducting the amount of steel per unit overlap, the steel amount can be reduced by about 2%. Due to the use of professional factory production, after the construction progress reaches the site, it is suspended to the working surface, and there is no need to set up a steel processing site on site, that is Save space and improve management level. At the same time, it can also solve the noise pollution problem caused by straightening and reinforcement and promote civilized construction on site.
