Movable type fireproof protection device for building seismic-isolation rubber supporting seat

The invention discloses a movable type fireproof protection device for a building seismic-isolation rubber supporting seat. The movable type fireproof protection device comprises inorganic fireproof plates and a flexible fireproof thermal insulation ring which surround the periphery of the supporting seat from inside to outside. The inorganic fireproof plates comprise the inorganic fireproof upperplate and the inorganic fireproof lower plate and are formed through embracing of a plurality of plates, the shapes of the side faces of every two adjacent plates are identical, and gaps between every two adjacent plates are filled with fireproof mortar; an anti-flaming expansion rubber sheet is arranged between the inorganic fireproof upper plate and the inorganic fireproof lower plate, the inorganic fireproof plates are connected with connecting steel rings, and the connecting steel rings are fixed to building buttresses or flange plates; and the top end of the flexible fireproof thermal insulation ring is fixed to
