The prefabricated column is fixed at the upper end face of the seismic isolation support column cap. A seam is reserved between the seismic isolation support column cap and the prefabricated beam, the part where the seismic isolation support column cap is connected with the seam is of a step shape, and a triangular grooved shear key is arranged at one end, connected with the seam, of the prefabricated beam. The reinforced-concrete-fitted node further comprises concrete poured into the seam and on the prefabricated beam. The reinforced-concrete-fitted seismic isolation node has the seismic performance similar to the seismic performance of a cast-in-place concrete structure, and the parts of the reinforced-concrete-fitted seismic isolation node are reliably connected. The utility model further relates to a fitted seismic isolation structure which comprises the reinforced-concrete-fitted seismic isolation node and a seismic isolation support. The seismic isolation support is fixedly connected with the lower end of the seismic isolation support column cap.
