By the upper connecting plate sealing plate, lead, multi-layer rubber, stiffened steel, protective layer rubber, under the sealing plate and the connection plate composition. Multi-layer rubber, stiffened steel plates constitute a multi-layer rubber bearing capacity and horizontal displacement of the building to bear the function of lead in the multi-layer rubber bearing shear deformation, the absorption of energy by plastic deformation, lead, through the dynamic recovery And the recrystallization process, as well as the role of rubber shear tension, the building automatically restored in situ. In response to the requirements of different lead cores and bridges, the isolation bearings can have different laminated structures, manufacturing processes and formulation to meet the required vertical stiffness, lateral deformation, damping, durability, overturning, etc. Performance requirements.
