Among them, seismic isolation rubber bearings are a very effective seismic isolation product with good bearing capacity and seismic resistance. At present, seismic isolation rubber bearings need to be connected to the ground foundation during installation. Generally, steel plates are embedded in the foundation, and the seismic isolation rubber bearings are then connected to the embedded steel plates through connectors. However, in the actual construction process, the cost of embedded parts is relatively high, and the construction is difficult. The concrete grouting at the bottom of the embedded parts is not easy to control, and there is a risk of false grouting and voids. Summary of the invention
