The present invention relates to a structure lifting apparatus having a locking device therein, wherein a safety jack nut included in a safety device structure as an internal locking device and a nut key rotating the same are used to move the safety jack nut downwards to come into contact with a support surface, so that a part of a load applied from the structure is dispersed in a vertical direction of the safety jack nut. The structure lifting apparatus comprises a bearing plate, a bearing plate support unit, a safety jack bolt, the safety jack nut, a cylinder, an external support, and the nut key.

    본 발명은 내부에 락킹 장치가 구비된 구조물 인상 장치에 관한 것으로, 안전장치 구조내 내부 락킹 장치로서 포함된 안전잭 너트 및 이를 회전시키는 너트키를 이용하여 상기 안전잭 너트를 하강 이동 및 지지면과의 접촉을 통하여 구조물로부터 작용하는 하중의 일부를 안전잭 너트의 수직 방향으로 분산시킬 수 있다.
