1. A core-pulling transfer device comprising:
temporary supports,
long-stroke hydraulic jacks and
a steel crossbeam;
wherein the temporary supports are configured to support on a bottom surface of a crossbeam of a reinforced concrete structure,
wherein ends of the crossbeam of the reinforced concrete structure have beam end through holes,
wherein the crossbeam of the reinforced concrete structure is connected with a force-transmitting structure column of the reinforced concrete structure,
wherein the long-stroke hydraulic jacks are configured to be symmetrically arranged on both sides of the force-transmitting structure column,
wherein the reinforced concrete structure comprises a demolition floor structure column and an upper end of the demolition floor structure column comprises a core-pulling hole,
wherein the steel crossbeam is configured to in clearance fit through the core-pulling hole, with both ends of the steel crossbeam extending out of the core-pulling hole,
wherein lower surfaces of the long-stroke hydraulic jacks are configured to be connected to a foundation, and upper surfaces of the long-stroke hydraulic jacks are configured to be propped against a lower surfaces of the steel crossbeam after the long-stroke hydraulic jacks extend through the beam end through holes.
