A separated bridge bearing is provided to minimize a space necessary to repair or replace the bridge bearing by forming a coupling hole and a guide groove at an upper plate for slide of a protrusion formed at an intermediate plate. A separated bridge bearing comprises a main body(10), a bearing plate(20), an intermediate plate(30), side blocks(13), an upper plate(40), and a base plate(50). The main body has a bearing mount(11) at the center and guides at two side ends. The bearing plate is mounted on the bearing mount. The bearing plate is overlaid with the intermediate plate. The side blocks are fixed to the guides to prevent the bearing plate and intermediate plate from separating. The upper plate is installed between the intermediate plate and a bridge slab. The base plate is fixed between the main body and a bridge pier by anchor bolts(59) and anchor sockets(58). A protrusion(35) is installed at the intermediate plate. A coupling hole(41) is formed for the protrusion at the upper plate. A guide groove(42) is formed at one part of the coupling hole. The protrusion slides into the coupling hole through the guide groove. A stopper member(45) is detachably installed at the guide groove. |
