Rigid connection devices provide for the horizontal fixation of structural systems. Alongside conventional structural bearings with locking MAURER also offers solutions for temporary fixation, so-called shock transmission units and break-off devices. In case of an earthquake these devices enable motion of the horizontal structural up-bearing.
MAURER Shock Transmission Units are hydraulic safety devices that lock at strong impulses, such as earthquake shocks or sudden braking on bridge constructions, and therefore clamp the construction. However, they are designed to allow shifting without much resistance if slow movements occur as in everyday usage. MAURER Load Limiters are hydraulic-safety devices that limit the reaction force upward by velocity-based control of oil flow. By using such elements, construction damage caused by extreme shifting velocities can be efficiently avoided.
MAURER Predetermined Break-Away Force restraints transmit normal horizontal forces from service and ultimate loads such as conventional structural bearings. Since mechanical features and breaking mechanisms are accurately composed with minimal tolerance, these safety devices break exactly at previously defined loads in case of an earthquake and thus protect the construction by subsequent isolation from the subsurface. MAURER Predetermined Break-Away Force Restraints are available, for example, as cleat structures and telescope devices.
