Description:
rebar upset forging machine GD-150 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
Applications:
1. Jiangsu Runyang Bridge in China
2. Jeddah Water Pump station in Saudi Arabia
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 t
