According to the present invention, a structure is lifted by a scaffolding structure, a hydraulic jack and a guiding rail of H-shaped steel fixed to the structure. The scaffolding structure has horizontal supporting members X and Y forming a horizontal plane and has vertical supporting member Z installed perpendicularly to X-Y. A scaffolding diagonal member (150) for preventing horizontal displacement is installed on X-Z and a scaffolding diagonal member (150) for preventing horizontal displacement is installed on Y-Z. A sliding guide is installed on the upper part of vertical supporting member Z to face the sliding guide. The guiding rail of H-shaped steel is fixed to a structure to be lifted, which corresponds to the sliding guide. The horizontal displacement of the structure is minimized as the sliding guide slides vertically while being enveloped by the upper flange of the guiding rail of H-shaped steel when the upper end of the rod of a hydraulic jack is supported by a horizontal support, which is fixed to the structure, and the structure is lifted by the pitching-lifting function of the rod of the hydraulic jack. |
