Description:
rebar threading machine GZL-45 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
When there is a need to splice bars of different sizes, it is allowable in most cases to reduce the size of the
larger bar and to use a standard coupler. However we also proposes&
