REINFORCING STEEL SPLICING SOLUTIONS

THREE-STEP MANUFACTURING PROCESS

1. Cutting	2. Cold Forging	3. Threading
The end of the reinforcing bar is sawn square.	The sawn end of the reinforcing bar is enlarged by a patented cold forging process. The core diameter of the bar is increased to a predetermined diameter.	Finally, the thread is mechanically cut onto the enlarged end of the bar.

The BARTEC® mechanical splice system consists in enlarging the reinforcing bar ends by cold-upsetting prior to threading them. The bars are cut square before the enlarging operation. The combination of the square cutting and the cold-upsetting reduces the length of the bar by approximately 40 to 75 mm on each end, depending on the bar size. Extra-long threads are used to assist alignment, or when joining bars that cannot be turned. All applications can thus be fulfilled by only one model of the coupler, thereby reducing inventory management to a minimum. Bar end preparation must be done exclusively with machines provided by Dextra. Consult us for technical details of our range of machinery.

SPLICING METHODS

Standard splice	Position splice	Type C assembly method
Easy connection by bar rotation until full thread engagement. Parallel thread : No risk of thread mis-match. No risk of cross-threading.	Even when both bars cannot be turned, the Bartec system uses a standard Bartec coupler (exactly the same as used for type A): 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.	Type C assembly method is similar to Type B, with the addition of a lock-nut to maintain the second bar in position


Caging splice	Transition splice	End anchors
To connect cages that haven't been pre-fabricated together or sets of bars that can't be brought butt to butt, Bartec Caging Splice is your solution. Both bars are threaded with a standard Bartec thread, and then the free rotating elements of the Caging Splice willÂ restore thread continuity and make the connection.	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 the Bartec system also proposes special transition couplers that conveniently avoid the difficult task of planning in advance the need of transitions	A convenient alternative to hooked bars to provide end anchorages in congested areas. Bartec 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 Bartec weldable couplers, which are specially made from low carbon steel and which have a large chamfer for bevel welding
