The welding network of steel bar can be divided into cold-rolled ribbed steel bar welding net, cold-drawn circular steel bar welding net and hot-rolled ribbed steel bar welding net, of which cold-rolled ribbed steel bar welding net is the most commonly used. According to the grade, diameter, length and spacing of steel bar, the welding steel bar net can be divided into two types, i.e. section steel welding steel bar net and custom-made welding steel bar net. The quality of welded steel bar net is strictly controlled by the factory. Control. Consumer Intelligent Consumption Line.
The mesh size, steel specifications and quality are strictly controlled to prevent the omission of manual gangs. This is powerful for ligation. There is an example of making mistakes and stopping work. Its mesh is a large steel. Good elasticity. The spacing is average and accurate. The strength of welded joints is high. As a result, the quality of the project has been greatly improved. Longitudinal and transverse reinforcement of welded steel mesh constitutes a mesh structure. The construction has good anchorage and average load distribution, which improves the seismic performance of reinforced concrete structures. According to practical tests, the cracks of paved roads with welded steel mesh can be reduced by more than 75%.
The design strength of a large number of circular steel bars is 210 N/mm (bungalow) and that of welded steel bars is 360 N/mm (bungalow). Based on the principle of equal strength replacement, considering comprehensive factors, using welded steel bars can save more than 30% of steel application. The steel bars are transported to the site after processing, so there is no loss.
Welded steel mesh can make construction work quicker. Only laying steel welding mesh according to the request can concrete be poured out, steel bar is cut in place, and the assistant strip can be saved as soon as one row is pressed. The working time can be saved by 50%-70%, which greatly speeds up the construction progress and shortens the construction period. Welded steel mesh is also called welding steel mesh, steel mesh, steel mesh, steel mesh, etc. Longitudinal steel bar and transverse steel bar are in a certain degree. Arranged in intervals and welded together at right angles and all intersections.
