DEMOLITION SYSTEM AND DEMOLITION METHOD
PROBLEM TO BE SOLVED: To provide a demolition system capable of demolishing an existing building in a short construction period.SOLUTION: A demolition system 2 comprises: a crane installation floor 20 including a portion of an existing floor 14 of an existing building 1; a supporting column 11A which supports the crane installation floor 20; a crane 30 which is installed on the crane installation floor 20; and a lifting and lowering device 40 which lowers the crane installation floor 20 along the supporting column 11A. The lifting and lowering device 40 has: a reaction member 41 installed on an upper edge of the supporting column 11A; a suspension material 42 installed on the reaction member 41; an engaging device 43 which is installed on the crane installation floor 20 and can be engaged with the supporting column 11A; and a lifting and lowering jack 44 which is installed on the engaging device 43 and pulls the suspension material 42. The reaction member 41 has: a pair of reaction beams 60; a connection beam 61 connecting the pair of reaction beams 60; and a pair of sliding beams 62 which can be moved along the reaction beam 60 and placed in contact with an upper face and a side face of the supporting column 11A.SELECTED DRAWING: Figure 5
【課題】短工期で既存構造物を解体できる解体システムを提供すること。【解決手段】解体システム２は、既存建物１の既存床１４の一部を含むクレーン設置床２０と、クレーン設置床２０を支持する支持柱１１Ａと、クレーン設置床２０上に設置されたクレーン３０と、クレーン設置床２０を支持柱１１Ａに沿って下降させる昇降装置４０と、を備える。昇降装置４０は、支持柱１１Ａの上端に取り付けられた反力部材４１と、反力部材４１に取り付けられた吊り材４２と、クレーン設置床２０に設けられて支持柱１１Ａに係止可能な係止装置４３と、係止装置４３に設けられて吊り材４２を引っ張る昇降ジャッキ４４と、を備える。反力部材４１は、一対の反力梁６０と、一対の反力梁６０同士を連結する連結梁６１と、反力梁６０に沿って移動可能でかつ支持柱１１Ａの上面および側面に当接可能な一対のスライド梁６２と、を備える。【選択図】図５
