Applications typiques
With rebar couplers, columns can be cast to their full height, resulting in a faster construction cycle.
Without couplers, a lap length is required for continuation bar connections. The formwork must be custom-made with holes for the rebars, which often leads to concrete leakage.
Couplers not only eliminate unnecessary rebar costs and reduce rebar wastage by up to 10%, but they also reduce rebar congestion at lap areas.
Couplers help maintain the load path and structural integrity, while also reducing the cost associated with the overlap length of rebar.
Bending and unbending the bars requires more tools and may increase the risk of bar breakage. Couplers make the installation of continuation bars easier.
To connect pre-fabricated cages, caging couplers offer a more flexible and faster method than traditional bar welding.
The use of couplers results in a faster construction cycle and more efficient rebar connections.
When space is limited on the project site for installing a tower crane for high-rise construction, an opening in the floor slabs is required. By leaving bridging couplers inside the slabs, reconnection becomes easier and more time-efficient.
