PROBLEM TO BE SOLVED: To enable pull-out work to be efficiently executed by limiting movement of a jack base 5 by a reaction force of a jack 7.SOLUTION: A pull-out device 4 includes: a jack base 5 that is fixed to an outer peripheral surface of a first column 1 by a metal band 11; a jack retainer 6 that is arranged in the state of abutting on an end surface 2a of a second column 2; a jack 7; and an auxiliary support tool 8 that is arranged adjacently to the jack base 5. An first inclined surface 39 of the jack base 5 and a second inclined surface 62 of the auxiliary support tool 8 are brought into contact with each other. When a reaction force of the jack 7 is received, a wedge action occurs to reliably inhibit movement of the jack base 5.SELECTED DRAWING: Figure 1 【課題】ジャッキ７の反力によるジャッキ台５の移動を制限し、効率よく引き抜き作業が行えるようにする。【解決手段】引き抜き装置４は、第１の柱１の外周面に金属バンド１１により固定されるジャッキ台５と、第２の柱２の端面２ａに当接して配置されるジャッキ受け具６と、ジャッキ７と、ジャッキ台５に隣接して配置される補助支持具８と、を備える。ジャッキ台５の第１傾斜面３９と補助支持具８の第２傾斜面６２は互いに接しており、ジャッキ７の反力を受けると、くさび作用が生じ、ジャッキ台５の移動が確実に阻止される。【選択図】図１
