Typically lap joints are provided to connecting reinforcement bars for continuity in reinforced. Though this is simple and easy method, it is not always appropriate OR feasible. Advantages of simplicity and economy in lap splicing is limited to smaller diameter bars. However in projects where larger diameter bars are involved, mechanical couplers offer the solution for splicing. Following are some of the advantages of mechanical splicing.




Rebar Coupler system advantages

Technically Superior:

Rebar Coupler system performs like continuous reinforcement.Independent of concrete, Splicing develops strength mechanically.Therefore provides ductility in RCC structures independent of condition of concrete.The continuity of spliced rebar offers excellent provision for grounding electrical current.

Designer friendly:

In dense reinforcement members, congestion of rebars is largely reduced by using coupler system. This helps improves concrete flow & consolidation. Rebar Coupler system provides greater flexibility in design options.The simplicity in detailing of reinforcement, particularly in reinforcement congestion zones minimizes the reinforcement fixing errors, detailing and fixing of seismic reinforcement becomes effortless.

Quality, cost and time advantages:

Rebar Coupler system offers quality, cost and time saving. No special skills or equipments are required for fixing couplers.Simple mechanical ways in adopting mechanical splicing compared to lapping, accelerates construction schedules for optimum cost and efficiency.Handling the rebar in convenient sizes saves on valuable crane time. In case of high diameter rebars, considerable length of rebars saves making the Rebar Coupler system  economical.
