The present invention relates to a bridge lifting device capable of lifting an upper plate of a bridge, which comprises: a hydraulic cylinder in which a rod is raised and lowered by supplied fluid; and a support unit mounted in an upper portion of the hydraulic cylinder to support the upper plate of the bridge. The support unit comprises: a first support formed of a metal material; a first elastic support layer formed of an elastic material on the first support; a second support formed of the metal material on the first elastic support layer; and a second elastic support layer formed of the elastic material of which a component is formed different from that of the first elastic support layer on the second support. Thus, the bridge lifting device and a bridge lifting method using the same can improve efficiency of tilting allowance and load distribution by the elastic support layers having different elastic deformation degrees according to vertical length.

    본 발명은 교량의 상판을 인상시킬 수 있도록 된 교량 인상장치에 관한 것으로서, 공급되는 유체에 의해 로드가 승하강되는 유압실린더와, 유압실린더의 상부에 장착되어 교량의 상판을 지지하는 지지유니트를 구비하고, 지지유니트는 금속소재로 형성된 제1지지체와, 제1지지체 위에 탄성소재로 형성된 제1탄성지지층과, 제1탄성지지층 위에 금속소재로 형성된 제2지지체와, 제2지지체 위에 제1탄성지지층과 성분이 다르게 형성된 탄성소재로 형성된 제2탄성지지층을 구비한다. 이러한 교량인상장치 및 이를 적용한 교량 인상방법에 의하면, 탄성적 변형 정도를 수직 길이에 따라 다르게 조성된 탄성지지층들에 의해 하중 분산 및 틸팅허용에 대한 효율성을 향상시킬 수 있는 장점을 제공한다.
