High damping rubber bearing
According to the different seismic technology performance of HDR bearing,the connection type between the bearing ontology and anchoring parts (or embedded parts),and the(connection)type between the bearing and anchoring parts of the beam and pier.HDR series bearing can be divided into two types as follows:
NO.1:The HDR bearing is installed on bridge pier and beam with sleeves and anchoring ord,the embedded steel plates are installed on the top and bottom of bearing ,the sleeves are fixed on the top steel plate and bottom steel plate of the bearing by assembling bolt,the top and bottom embedded steel plates are designed to be welded installing with sleeves.
NO. 2:The HDR bearing is installed on the bridge pier and bearn with sleeves and anchorimg rod. The embedded steel plates are installed on the top of bearing but the bottom of the bearing have no embedded steel plates installed. The sleeves are fixed on the bottom seal layer steel plate by assembling bolt. The top embedded steel plate is installed on the top seal layer steel plate by shearing force cogged. The top embedded steel plates are designed to be welded installing with sleeves.
