Description
The cold extrusion connection of steel bars is to insert two steel bars to be connected into the steel sleeve, and use the extrusion connection device to extrude the steel sleeve in the radial direction to cause plastic deformation. The mechanical bite produced by the transverse ribs is integrated into a method of connecting steel bars.
This process is a mechanical connection method, which has the advantages of high strength, strong rigidity, unified humanization, fast connection, easy control, and all-weather construction. This process standard is applicable to the cold extrusion connection technology of various types of reinforced concrete structures with diameters of 20-40mm Ⅰ and Ⅱ grade steel bars in industrial and civil buildings, high-rise buildings and foundations.
