The beneficial effect of the present application is to provide a building seismic isolation device with better seismic isolation effect.

[0004] However, in this application, there is no corresponding connection for pipelines in industrial and civil buildings. Under earthquake-resistant conditions, pipelines are easily damaged, especially gas pipelines. The secondary hazard source caused by damage is still very large. Utility Model Content
