The role of the bridge damping block is to connect. The bridge rubber damping block is installed on the pier and the top supports the upper structure of the bridge. The function of the shock-absorbing rubber pad is to fix the superstructure to the abutment, to bear various forces acting on the superstructure, and to transmit it reliably to the abutment. Its use for bridge construction, bridge applications. The last question bridge rubber cushion specifications. It is generally round and square. The specific size has no fixed number.
The general rubber shock-proof blocks are designed to prefabricate or cast-in-place bridge joints, mainly to buffer the thrust.
Bridge rubber bearings are classified according to the possibility of deformation, materials used, and structure.
1. According to the possibility of deformation of the rubber bearing for bridge
Mesh rubber bearings
1) Fixed bearing;
2) one-way activity bearing;
3) Multi-directional activity bearing.
2. According to the material used in the bearing
1) Steel bearings: flat plate bearings, arc bearings, rocker bearings, roller bearing.
2) Whether to bring the sliding ability to branch seats: sliding bearings, fixed bearings.
3) Rubber bearing: Plate rubber bearings (including PTFE sliding plate rubber bearings), pot rubber bearings, lead rubber bearings, [1] high damping rubber bearings.
3. According to the structure of the bearing
Spherical bearing
1) Arc bearing
2) Shaft bearing
3) Roller bearings
4) Plate rubber bearings and PTFE platen rubber bearings
5) pot rubber bearings
6) Spherical steel bearings
7) Pull pressure bearing etc.
