Pillar lifting jig and pillar lifting method

摘要

PROBLEM TO BE SOLVED: To appropriately lift a column member having two flanges that face each other.SOLUTION: A column lifting jig 1 is for lifting a column 10 having two flanges 13, 14 that face each other, and includes a base part 2, and an advancing/retracting part 4 that may advance/retract such that to change a protruded amount from a bottom surface of the base part 2. The base part 2 is fixed by being inserted between the two flanges 13, 14 from a front edge side and fixed while being held between the flanges. The advancing/retracting part 4 is inclined so as to come closer to the front edge of the base part 2 toward a tip of the advancing/retracting part 4. Furthermore, the advancing/retracting part 4 presses a top surface of an upper beam flange 21, as the tip thereof moves in a direction to approach the top surface of the upper beam flange 21 and a protruded amount from the bottom surface of the base part 2 increases.SELECTED DRAWING: Figure 5
