Abstract
Description
Technical Field
[0001] This utility model relates to the field of seismic isolation bearing technology, and in particular to a device for preventing the displacement of seismic isolation bearings during concrete pouring. Background Technology
[0002] Seismic isolation bearings are support devices installed on structures to achieve seismic isolation requirements. They consist of an isolation layer added between the superstructure and the foundation, with rubber bearings providing a flexible connection to the ground. This technology can neutralize approximately 80% of an earthquake's energy. Currently, most use lead-core rubber bearings, which are laminated rubber seismic isolation bearings containing vertical lead cores. Besides bearing the structure's weight and horizontal forces, the plastic deformation of the lead core absorbs energy through hysteresis damping, and the rubber provides horizontal restoring force. However, the main cause of displacement during concrete pouring is the unevenness of the installation surface. Existing seismic isolation bearings cannot maintain constant awareness of the horizontal state of the connecting steel plates during installation; any deviation will lead to bearing displacement after pouring. Therefore, we have developed a device to prevent seismic isolation bearing displacement during concrete pouring. Utility Model Content
