A rocking hinge for a reinforced concrete bridge pier
By designing swing hinges on reinforced concrete bridge piers, utilizing PT reinforcement and energy dissipators to provide self-resetting and energy dissipation capabilities, and combining this with crash barriers to limit displacement, the problem of large damage and difficult repair of traditional bridge piers during earthquakes has been solved, achieving high seismic performance and rapid recovery.

Abstract
The utility model discloses a kind of rocking hinges for reinforced concrete bridge pier, it is related to concrete bridge pier technical field, comprising: PT bar, rotating fulcrum, bar under support anchor point, chassis bolt hole, chassis pedestal, crash barrier, energy consumer, workbench, bar upper support anchor point and bridge pier;The workbench and chassis pedestal are matched by recess and shear pin, limit transverse movement;The PT bar one end is fixed in the recess in the bottom of chassis pedestal, and the other end is anchored to the bar upper support anchor point on the top of bridge pier.The utility model uses rocking hinges for reinforced concrete bridge pier in the construction process of bridge pier displacement self-recovery system, relative to traditional post-earthquake treatment mode, it has great improvement in design theory, reliability, the opening of rocking joint significantly reduces the tensile failure of original plastic hinge zone concrete, while unbound PT bar provides restoring force, reduces the residual displacement of pier column.
