Description:
Rebar forging machine with CE certificate 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 special transition couplers that
conveniently avoid the difficult task of planning in advance the need of transitions.
End anchors
A convenient alternative to hooked bars to provide end anchorages in congested areas. Standard
anchorage heads are circular and have a net bearing area of 4 times or 9 times the cross-section of the bar, but can also be made to order in other shapes or dimensions to fit the application
requirement.
Weldable couplers
For composite construction where concrete reinforcement bars must be welded to structural steel, use
weldable couplers, which are specially made from low carbon steel and which have a large chamfer for
bevel welding.
Applications:
1. Jiangsu Runyang Bridge in China
2. Jeddah Water Pump station in Saudi Arabia
Competitive Advantage:
- No reduction of the bar cross section area.
- Full-Tension splice: Bar-break under tensile load.
- Allows full ductile elongation of bars.
- Easy installation, no torque wrench required.
- One standard coupler for splicing requirements(Standard/Position)
- Manufactured under strict quality assurance plan ISO 9001, Third party tested.
- Full traceability of material origin and production batch.
- Coupler suitable for seismic areas.
- Tested under reverse-cyclic conditions.
- Solves bar congestion problems.
- No staggering of splices bars required.
