Introduction
Reinforced mesh is a mesh made of longitudinal and transverse steel bars crisscrossed by binding or welding. It is one of the new technologies promoted and applied in the construction industry of the Ministry of Construction.
Theoretical weight calculation formula of reinforced mesh:
Theoretical weight of reinforced mesh The length of the steel bars used in the reinforced mesh * Wire diameter * Wire diameter *. (Rebar.3/)
The application of reinforced mesh in industry and Beams, columns, floors, roofs, walls, concrete pavements, bridge deck paving, airport runways, tunnel linings, box culverts, dock floors, prefabricated components and other fields for civil houses.
Classification
According to raw materials, it can be divided into: cold-rolled ribbed steel mesh, cold-drawn smooth round steel mesh, hot-rolled ribbed steel mesh, among which cold-rolled ribbed steel mesh is the most widely used.
Cold-drawn plain round steel bar mesh
Cold-drawn plain round steel bar welded mesh is a high-strength, high-efficiency construction material for concrete reinforcement. It is produced in the factory through automated production lines and will have the same or different diameters. The longitudinal and transverse steel bars are arranged vertically at a certain distance, and all intersection points are resistance spot welded together. It is a high-efficiency new construction steel product that is produced on a large scale in a factory to replace manual binding of loose steel bars.
The diameter of cold drawn smooth round steel welded mesh is -.
Cold-drawn smooth round steel bar welded mesh should be made of Class B cold-drawn smooth steel bars.
Hot-rolled ribbed steel mesh
According to raw materials, it can be divided into: cold-rolled ribbed steel mesh, cold-drawn smooth round steel mesh, hot-rolled ribbed steel mesh, among which cold-rolled ribbed steel mesh is the most widely used widely.

Spacing
Saving the amount of steel bars: Compared with ordinary grade steel bars in the same volume of concrete structures. The design strength value of cold-rolled steel bars and welded mesh has been increased from 3 to 3, so the amount of steel bars can be relatively reduced by more than 3. In addition, since it is produced on an engineering automated production line, the loss of the steel mesh is minimal.
Improve work efficiency: The use of welded steel mesh can eliminate the need for on-site steel bar straightening, cutting, and placement one by one.
It can save up to more than 10 hours of work, greatly simplifying the construction process, speeding up the construction progress, and shortening the time. the construction period.
Reduce project costs: Although the unit price of welded steel mesh is higher than that of loose steel bars. However, comprehensively considering factors such as material usage, construction speed, labor costs, material loss, on-site processing costs, mechanical processing costs, and site, it can save more than 3% of steel, shorten the construction period, and reduce project costs by more than 3%, which has considerable economic benefits.
