Upsetting splice is a parallel threaded rebar mechanical splice designed for the connection of concrete reinforcement bars, for diameters 16-40mm.
The full performance of upsetting rebar splices is stronger than the reinforcement bar and guarantees bar break under tensile stress.
PROFESSING STEP
The ends of the bars to be joined are cut square and enlarged by cold forging to increase their core diameter and so ensure that the joint is stronger than the bar. The couplers are usually supplied attached to the reinforcing bar.
1. Use the upsetting machine to thicken the end of rebar.
2. Use the steel bar threading (cut) machine to make thread on the end of rebar.
3. Connect the two rebar end with the upsetting rebar couplers.
