Construction of welded wire mesh on the floor of the factory floor replaces the manual wire mesh that is easy to lose steel in the process. Hang wire mesh has many outstanding advantages compared to hand-tied wire mesh, so it is highly appreciated by contractors for its efficiency and widely used in most construction projects.
Construction of welded wire mesh is manufactured from high strength cold drawn steel wire and undergoes automatic welding process by molten electrode contact cave technology, so it has higher bearing capacity than welded by wire mesh welding machine.
Constructed in accordance with the prescribed standards of welded wire mesh made from steel wire with a diameter of 4mm to 12mm in the design of installation, installation and acceptance at the same time stipulating the use of welded wire mesh in reinforced concrete structures. plate
Meshing method: fabricated by placing the weft and warp yarns in the specified way, and linked together at the intersection point by spot welding. You follow the welding instructions for the steel mortar. Splicing steel wire to create wire mesh needs to be done by butt welding
According to the volume of wire mesh: determined according to the standard volume in the design drawings. With special narrow mesh, it is possible to determine the mass of the wire mesh by cypress based on the density of the steel by 7,850 kh/m3, or weigh the entire coil or mesh piece.
Determine the allowable tolerances according to the construction drawings
The permissible yarn pitch tolerance does not exceed 7.5% of the standard yarn pitch or not more than 15mm from the standard pitch. The number of yarn steps between the two outermost yarns is also a parameter to determine the standard yarn pitch. Also allowable tolerance on volume per 1m2 is + - 6%. The tolerance also shows the mesh size is + - 0.5 % but should not exceed 25mm.
Specified standards for welds
Wire mesh is manufactured from plain steel wire with diameter from 5mm - 12mm and the yarn sizes do not differ by more than 3mm in a piece of mesh, the minimum average shear force in the weld is not less than 250xA in newtons. (N) A is the effective weft area of the warp in square millimeters (mm2). The above 2 types of steel do not need to comply with the regulations on cutting force in the weld.
Stage of inspection and acceptance of items
By two options
+ An investment representative who supervises all stages of the supplier of welded wire mesh is provided with standard indicators and production materials to prove that the required quality wire mesh has been calculated on the sheet. construction drawing. Access to testing and research to produce welded wire mesh products transported to construction sites.
+ Inspect and review the facility for acceptance of welded wire mesh construction products and the certificate of weld materials that have been tested to satisfy the requirements and the actual factory floor construction results to ensure the load when put into operation. factory in operation.
Construction of welded wire mesh is widely used for many items: factory floor, high-rise building floor, concrete roof, concrete wall, retaining wall, earth retaining wall, hard wall, elevator wall, swimming pool, tank water, wastewater treatment systems, ditch systems, sewers, prefabricated concrete structures, pavements, corridors, concrete freight roads, internal roads of industrial works, raft foundations, column foundation, widely applied in electrical cable tray system in manufacturing plants.
Construction of welded wire mesh reduces labor costs and supervision at the construction site. Construction of welded wire mesh is manufactured by the factory with modern machinery to improve the construction schedule. Reducing the weight of the floor increases the bearing capacity of the floor. Reduce the cost of controlling steel loss, labor costs. Transportation, installation and replacement of welded wire mesh is easy and convenient.
Quotes apply flexibly in a variety of short and long sizes of welded mesh D4, D5, D6, D7, D8, D9, D10: A50x50, 100x100, 150x150, 200x200, 250x250. Depending on the item where the standard requirements for large quantities are applied, there will be an optimal calculation of quality and cost.
