A BRIDGE BEARING APPARATUS OF A FRICTION TYPE AND A RUBBER TYPE REINFORCED A HORIZONTAL STIFFNESS

摘要

The present invention is to provide a rubber type bridge bearing apparatus and a friction type bridge bearing apparatus with reinforced horizontal rigidity, which can efficiently control horizontal force and relative displacement of a bridge axis direction or a perpendicular direction. The present invention provided to achieve the purpose is configured to comprise: an upper plate (31) installed on the lower surface of an upper structure of the bridge; a lower plate (32) installed on the upper surface of the bridge or a pier; a hemispherical groove (34) recessed to move a ball bearing (33) in the lower surface of the upper plate (31); and the ball bearing (33) installed between the lower plate and the upper plate.
