Rebar couplers are employed in reinforced concrete cement structures to change the system of lapping & welding in reinforcement. Couplers are employed where the long length of the bar is required or when connecting the additional bars to the end of existing bars are connected by wire next to each other.

There is a waste of bars in the welding system & lapping system, alternative system is employed called a rebar coupler or coupler in reinforcement that gives an end-to-end connection for the continuous reinforcement of any structure.

The coupler is cheap and cost-efficient unlike the lapping system, where some portion of the bar is wasted due to lapping. The Couplers are generally known as mechanical splices. It is employed in all construction such as the construction of buildings, bridges, dams, towers, etc.

There are primarily two types of rebar couplers in reinforcement. They are: threaded rebar coupler, roll thread coupler, cold forged rebar coupler, non-threaded coupler, crimping rebar coupler, MBT coupler.

Some benefits of the coupler in reinforcement are as follows;

a. It has excellent quality control & is easy to handle.

b. The load transfer is reasonable.

c. The coupler does not make congestion.

d. The continuity load path is valid.

e. The rebar coupler is very economical compared to all the systems of joints in reinforcement.

f. The Coupler expands the work speed by short installment.

g. The connection check is easy & simple.

h. It enhances the service of the bar by not wasting bars like the lapping.

i. The coupler decreases the lapping length analysis.

j. It enhances structural integrity.
