[0002] A building structure shock absorption device is a technology or system that protects the safety of buildings and their internal personnel by isolating and consuming seismic energy. Building structure shock absorption devices mainly include seismic isolation technology and energy dissipation shock absorption technology. Seismic isolation technology reduces the impact of ground vibrations on buildings by adding a seismic isolation layer between the structure and the foundation. Energy dissipation shock absorption technology, on the other hand, uses energy dissipation devices to absorb and disperse seismic energy, reducing the degree of shaking of buildings. Commonly used seismic isolation devices include rubber seismic isolation bearings and metal seismic isolation bearings. A rubber seismic isolation bearing has an internal skeleton plate and functional rubber bonded layer by layer, with a protective rubber sleeve wrapped around the outer layer, and flange plates welded at both the upper and lower ends.
