The diameter of Dalian mesh and welded mesh reinforcement is 4-14mm, in which 0.5mm progressive diameter can be used. Considering the transportation conditions, the length and width of the welding network should not exceed 12m and 3.4m respectively. The spacing of steel bars (or longitudinal bars) in the manufacturing direction of welded mesh should be 100, 150, 200 mm, and the spacing of steel bars in the other direction is generally 100, 150, 200, 300 mm, sometimes up to 400 mm.


Domestic development overview: reinforcing mesh is also known as: welded reinforcing mesh, welded reinforcing mesh, welded reinforcing mesh distribution reinforcement direction support is provided with mat, if the bottom mesh and mat need to be provided with lap joints, each mesh shall have at least one main stress bar within the lap range, and the lap length shall not be less than 20d (D is the diameter of the distribution bar), and shall not be less than 150 mm. Strengthen the crack resistance of concrete.


It has better comprehensive economic benefits. Under strict quality control of the factory, welded steel fabric can improve the anti-seismic and anti crack performance and save steel consumption. Speeding up the construction progress and using the welded steel mesh can make the project construction faster. As long as the welded steel mesh is laid as required, the concrete can be poured without cutting, placing one by one, binding and other links.


It can save 50% - 70% of working hours, greatly accelerate the construction progress and shorten the construction period. No lap joint shall be set for the welding mesh of the lower reinforcement in the short span direction of the cast-in-place two-way slab; or the binding reinforcement shall be used to extend into the support, and the lap length and construction requirements shall conform to the provisions of JGJ 114-2003 technical specification for concrete structure with welded mesh of reinforcement.


The longitudinal reinforcement and transverse reinforcement of the two-way slab are respectively welded with the non stressed reinforcement to form the longitudinal network and the transverse network, which are respectively inserted into the corresponding beams during installation. The application of welded steel mesh in cement concrete pavement of highway has been greatly improved. When the floor bottom net is connected with the column, the slab extends into the lower longitudinal stress reinforcement of the support.
