LIFTING JACK AND METHOD FOR CORRECTING THE POSITION OF SLAB PANEL USING THE SAME

摘要

PURPOSE: A lifting jack and a method for correcting a slab panel position are provided to be used in correcting both height and direction of a panel in a precast slab track system by very easily installing a lifting jack. CONSTITUTION: A lifting jack (1) comprises a bottom plate (10), a sliding member (20), a bottom plate bolt (30), a body portion (40), and an axial bolt (50). The sliding member is slidingly combined into the bottom plate in a horizontal direction. The bottom plate bolt contacts the side of the sliding member to push the sliding member in a horizontal direction. The body portion is movable in a horizontal direction along with the sliding member, and is combined to be movable in a vertical direction, separately from the sliding member. The axial bolt pushes the top surface of the sliding member in order to increase the body portion.
