Mechanical reinforcing steel connections enable the force-locked connection of two concreting sections. Due to the socket joint, the formwork shell does not need to be pierced, which reduces time and material costs. Due to the full joint with a diameter of 12 to 32 mm, much higher forces in the joint can be transmitted than with reinforcement boxes.
To accelerate the construction process, the bolted connections can be delivered pre-assembled in reinforcement boxes. Installation on the formwork then takes place as for the rebend connection.
