[0002] Seismic isolation bearings refer to supporting devices that are installed in structures to meet seismic isolation requirements. Seismic isolation layers are added between the superstructure and the foundation, and rubber seismic isolation bearings are installed to provide a soft connection to the ground. Through this technology, about 80% of the energy of an earthquake can be offset.

[0003] When installing the existing seismic isolation bearing, the mounting seat of the seismic isolation bearing is fixed to the pre-buried fixing seat by a bolt structure, and the bolt structure will be corroded and rusted. When the seismic isolation bearing needs to be replaced or maintained, the rusted bolts may make it impossible to disassemble or cause damage to the screw holes, which makes it inconvenient to replace or maintain the seismic isolation bearing at a later time. Therefore, we propose a building construction rubber seismic isolation bearing to solve the problem raised. Utility Model Content
