Description:

Rebar upset forging parallel thread machine is a parallel-threaded mechanical splicing system designed for the connection of concrete reinforcing bars from Ø 12 to 40 mm.

Designed and manufactured in compliance with ACI 318, IBC 2006, BS 8110, Eurocode 2, DIN 1045.

Machine:

A. Standard machine

B. Automatic machine

steps process

1. Cutting

The end of the reinforcing bar is sawn square.

2. Cold forging

The sawn end of the reinforcing bar is then enlarged by a patented cold forging process. The core diameter of the bar is increased to a pre-determined diameter.

3. Threading

Finally, the thread is mechanically cut onto the enlarged end of the bar.

Splicing methods

Standard splice  

Easy connection by bar rotation until full thread engagement. Parallel thread : No risk of thread mis-match. No risk of cross-threading.   

Position splice

Even when both bars cannot be turned, this system uses a standard coupler: The coupler is fully engaged onto the extended thread of the connecting bar. The assembly is simply completed by butting the bars end to end and screwing back the coupler onto the first bar until full engagement. lock-nut to maintain the second bar in position. 

Bridging splice

When the bars cannot be brought butt to butt (as it may happen in cages manufacturing), Bridging splices are the answer. Both bars are threaded with a standard thread, and a “Bridging Assembly Set” is used to connect  them.  

Transition splice
