PROBLEM TO BE SOLVED: To permit departure and an easy lifting of a steel member engaged with a structure, making it possible to perform remote control, thereby improving work efficiency.SOLUTION: To provide an auxiliary lifting device 1 includes: a body frame 4 which is used when a girder 2 connected onto a column joint 3A by engagement is lifted and decomposed, and which is suspended by a lifting means; a clamp mechanism 6 disposed in the body frame 4 so as to hold the girder 2; a lifting cylinder 5 to raise the body frame 4 by taking reaction force with respect to the column joint 3A; and an insertion mechanism 7 that remainably inserts a spacer 7A into a gap between the girder 2 raised by the holding via the clamp mechanism 6 and the column joint 3A.SELECTED DRAWING: Figure 1

    【課題】構造物に対して嵌合する鉄骨部材を離脱させて容易に吊り上げることが可能となるうえ、遠隔操作を可能とすることで作業効率を向上させることができる。【解決手段】柱仕口3A上に嵌合により接合された大梁2を吊り上げて解体する際に用いられ、揚重手段によって吊り下げられる本体フレーム4と、本体フレーム4に設けられ、大梁2を把持可能に設けられたクランプ機構6と、柱仕口3Aに対して反力を取って本体フレーム4を上昇させる持上げシリンダ5と、クランプ機構6での把持によって上昇させた大梁2と柱仕口3Aとの間の隙間にスペーサ7Aを残置可能に挿入させる差込み機構7と、を備えた吊上げ補助装置1を提供する。【選択図】図1
