A core-pulling transfer device for reverse demolition of reinforced concrete structures comprises temporary supports, long-stroke hydraulic jacks and steel crossbeams. The temporary supports are supported on bottom surfaces of bottom crossbeams of the reinforced concrete structure, and a beam end through hole is formed in each end, connected with a force-transmitting structure column, of each bottom crossbeam. Two long-stroke hydraulic jacks are symmetrically arranged on both sides of each force-transmitting structure column. Core-pulling holes are formed in upper end sides of demolition floor structure columns. One steel crossbeam is in clearance fit with each core-pulling hole, and both ends of each steel crossbeam extend out of the corresponding core-pulling hole. The device can quickly carry out vertical load transfer of the reinforced concrete structure, smoothly transfer vertical force, and achieve a safe reverse demolition construction process.
