The Process Description of Cold pressing Coupler Connection

Cold pressing Coupler connection method is to move the rebar connection bars (should ribbed) Insert the end of a special rebar coupler, the rebar coupler compression using an extruder, it is plastically deformed by the deformation of the rebar coupler with ribbed steel mechanical occlusion clamping force to achieve reinforced the connection. This cold pressing coupler connection method of radial and axial extrusion extrusion two kinds.
According to the radial for radial compression sleeve on the connection method should conform extrusion "ribbed rebar cold pressing coupler Technical Specifications" (JGJ108-96) requirements.
Level of performance has always been the case A and B grade two; ribbed bars of different diameters can connect using extrusion method, when the rebar coupler ends of equal diameter and wall thickness, diameter of rebar being connected does not differ should be greater than 5mm.
Process Principle
extruder hanging on the trolley shelf, by the tension coil spring balancer changes adjust its height, and balance the weight of the operator handheld extruder basically in weightlessness; squeeze machine installed in the high-pressure pump to provide a small car pressure source.
