The invention provides a slab-
beam column seismic-isolation connection device. The slab-
beam column seismic-isolation connection device comprises a slab-column isolation component and slab-beam
cushion layers, wherein the inner side and the outer side of the section of the slab-column isolation component are both square, and the four slab-beam
cushion layers are arranged in different directions. The inner side of the slab-column isolation component is matched with the section of a column unit, the outer side of the slab-column isolation component is matched with a hole of a precast floor unit,after the slab-column isolation component is installed on the column unit in place, the slab-beam
cushion layers precisely make contact with the top surfaces of the corresponding beam units, and thewidth of each slab-beam cushion layer is larger than the width of the top surface of the corresponding beam unit.
