RWL Double Wire Loop Boxes consist of two high strength steel wire and a steel box. They also offer a unique solution for joining double walls to precast element as they provide design resistance in all directions.
When the joint between concrete wall elements is loaded, the longitudinal shear force in the joint is divided to an angled compression component and a horizontal pull component at the indented joint. RWL wire rope loop transfers the shear forces acting in the joint between concrete wall elements by the pull component of the wire rope and the compression component formed by the steel boxes and the seam.
