 Twist-on connectors and rebend connections in protective boxes are user-friendly system solutions for connecting reinforcement between different construction and concrete sections. Approved flexible steel cable loops and column shoes are suitable means for connecting precast concrete walls and columns. While in the past the formwork in transition areas of the reinforcement was frequently cut, reinforcement connections are easier and quicker to use, even on modern formwork elements.

Twist-on connections are conventional ribbed reinforcement steels with threaded ends that are screwed into the coupling bars of the first pouring section at the site. The use of screwed-on connection bars obviates the need for double reinforcement layers at joints, which is of special advantage in highly-reinforced members, e.g. columns, and eliminates extreme reinforcement concentrations. High-quality approved twist-on connectors ensure a secure mechanical connection, both for static and non-static loadings. Backbending reinforcement in protective boxes are delivered as complete systems and...
