STRUCTURE DISMANTLING SYSTEM AND STRUCTURE DISMANTLING METHOD
To provide a structure dismantling system capable of facilitating jack-down work.SOLUTION: A structure dismantling system 2 includes a crane installation floor 20, a support column 11A, and a lifting device 22. The lifting device 22 comprises: a reaction member 50 attached to an upper end of the support column 11A; a suspending material 51 wound around a pulley 612 of the reaction member 50 and having one end side connected to the crane installation floor 20; and a strand jack 52 provided on the crane installation floor 20 and pulling the other end side of the suspending material 51. The reaction member 50 includes: a box member 60 overlaid on the upper end of the support column 11A; a reaction beam 61 provided on the box member 60 and extending substantially horizontally; a temporary fixing air jack 62 provided on an inner wall surface of the box member 60 and abutting on a side surface of the support column 11A; and a winding drum 64 provided on a side surface of the box member 60 and winding up an air hose 63 of the air jack 62.SELECTED DRAWING: Figure 2
【課題】ジャッキダウン作業を円滑にできる構造物解体システムを提供すること。【解決手段】構造物解体システム２は、クレーン設置床２０、支持柱１１Ａ、および昇降装置２２を備える。昇降装置２２は、支持柱１１Ａの上端に取り付けられた反力部材５０と、反力部材５０の滑車６１２に巻かれて一端側がクレーン設置床２０に連結された吊り材５１と、クレーン設置床２０に設けられて吊り材５１の他端側を引っ張るストランドジャッキ５２と、を備える。反力部材５０は、支持柱１１Ａの上端に被せられたボックス部材６０と、ボックス部材６０の上に設けられて略水平に延びる反力梁６１と、ボックス部材６０の内壁面に設けられて支持柱１１Ａの側面に当接可能な仮固定用のエアジャッキ６２と、ボックス部材６０の側面に設けられてエアジャッキ６２のエアホース６３が巻き取られた巻き取りドラム６４と、を備える。【選択図】図２
