Steel welded mesh is manufactured in factories, using specialized welding machine will be the same or different diameters of the longitudinal and transverse reinforcement, with the resistance spot welding (low voltage, high current, welding the contact time is very short) mesh welded formed steel products. Vertical and horizontal steel reinforcement were arranged a certain distance and at right angles to each other, all cross-point by the resistance spot welding together steel mesh. Steel mesh welding process control by computer, production, welding quality and good mechanical properties of welded steel before and after virtually no change, but also can be used CPB550 grade cold drawn round steel production.
The advantages of welded steel:
1, to protect quality of the project
Steel welded in the factory under strict quality control, from fully automatic, intelligent production line made of. Mesh size, bar size and quality have been strictly controlled. Avoid artificial banding net omission lashing not strong, lashing errors and jerry-building occasions. The mesh stiffness, flexibility, spacing evenly accurate, high weld strength. Thus greatly improve the quality of the project.
2 and improve earthquake, crack resistance
The longitudinal reinforcement of welded steel and horizontal bars forming network structure, so Bond is good and concrete, to withstand the load evenly spread distribution, significantly improve the crack resistance of reinforced concrete structures seismic performance. According to the actual test, road construction welded wire mesh bandage than human, more than 75% can reduce the occurrence of cracks.
3, cut the amount of reinforced
Extensive use of the disk is a round steel design strength value 210N/mm, and the design strength of welded steel value 360N/mm, substitution according to the principles of equal strength, consider a combination of factors, the use of welded steel can save over 30% steel usage. And transported to the site after the steel mesh without further processing, so no loss.
4, speed up the construction progress
Use of welded steel, can become efficient construction. Just laying of welded steel required good, you can pour concrete, eliminating the need for field cutting steel, one by one place, and such links banding. --- 50% saving 70% of working hours, greatly accelerate the construction schedule, shorten the construction period.
5, lower project cost
Although priced higher than the bulk of welded steel support bar, but the comprehensive consideration of material consumption, material consumption, construction speed, ease of construction, labor costs, on-site processing costs, machining costs and other factors, can reduce the cost of 5% of the steel works - 10%, with considerable economic benefits
