Transition Coupler for Rebars Connection From 12-40mm
As one kind of parallel thread connection technology, it has following advantages:
1,Tensile strength of connection point is equal to connected bar;
2,only 1 machine, needs 1 worker, It can process rebar whose diameter is between 16mm and 40mm.
3,Rib peeling completed by one-time, steel bar without any ribs, roll screw thread with fast speed, the thread is very perfect after rolling.
4,Highly automatic and easy to operate;
5,Roll stamping after steel bar rib peeling, with good shape of thread, high precision and
conformed diameter size;
6,Rolling wheel has long service period, low additive cost of connector;
7,Easy to adjust, when rolling steel bars of different specifications, adjustments can be
made without change any chasers, provided that the screw pitch are the same.
Rib peeling roll stamping system contains:
1. Rib peeling roll stamping machine(JHB400) and couplers.
Working principle:
1. Slice up the end of rebar;
2. Peel the rib of the end of rebar with Dextra Type Rebar roltec threading Machine
3. Abutting joint two ends of rebar with Transition Coupler for Rebars Connection From 12-40mm
2. Rebar roltec coupler parameter, we can also produce according to your size requirement!

4. Other rebar Splicing methods of JBCZ:

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, the Rolltec system uses a standard Rolltec 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.
This assembly method is similar to Type B, with the addition of a lock-nut to maintain the second bar in position.
Caging splice



If cages have not been pre-fabricated together or can't be brought butt-to-butt, Rolltec Caging Splice is your assembly solution. Both bars are threaded with a standard Rolltec thread, then the free rotating elements of the Caging Splice will restore thread continuity and make the connection.
Transition splice
The Rolltec system offers special transition couplers between various rebar sizes that conveniently avoid the difficult task of planning in advance the need of transitions.
Weldable couplers
For composite construction where concrete reinforcement bars must be welded to structural steel, Rolltec weldable couplers, specially made from low carbon steel, are available.
End anchors
A convenient alternative to hooked bars to provide end anchorages in congested areas.
Rolltec 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.
