The rubber isolation bearing is made of laminated rubber and sandwich steel plate, which are vulcanized and bonded at high temperature. When the bearing is subjected to vertical load, the lateral deformation of the rubber layer is restrained, which makes the bearing have great vertical bearing capacity; When the bearing receives the horizontal load, the relative lateral displacement of its rubber layer is greatly reduced, so that the rubber pad can reach a large overall lateral displacement without instability, and adhere to a small horizontal stiffness.

Because the sandwich steel plate is tightly bonded with the rubber layer, the rubber layer can also accept tension under the vertical seismic effect. Therefore, rubber isolation bearing is an ambitious isolation device with large vertical bearing capacity, small horizontal stiffness, large allowable horizontal lateral displacement, and can accept the vertical seismic effect. Common rubber isolation bearings shall include general rubber isolation bearings, lead rubber isolation bearings and high damping rubber isolation bearings.

Generally, rubber spread bearings only have the characteristics of high elasticity and low damping, and their damping ratio is about 0.03~0.05, which need to be used together with other dampers. Lead-core rubber isolation bearing is made by filling lead core into general rubber isolation bearing. Pure lead data has lower yield point and higher plastic deformation energy dissipation ability, and rubber bearing has binding force on damping data lead, making it only shear deformation, so it can effectively improve the initial stiffness and damping characteristics of rubber bearing.

The above is the classification and use principle of rubber isolation bearings introduced by the bridge bearing manufacturer in retail and wholesale. If you still don't understand anything, you can contact us or leave a message.
