DEMOLITION SYSTEM OF EXISTING STRUCTURE
To provide a demolition method of an existing structure which can reduce a construction cost.SOLUTION: A demolition system 2 comprises: a crane installation floor 20 which is constructed on a top floor of an existing building 1; a columnar support 11A being an existing column 11 for supporting the crane installation floor 20; a crane 21 installed on the crane installation floor 20; a lift 22 for descending the crane installation floor 20 along the columnar support 11A; and a lock device 23 which is arranged at the crane installation floor 20, and lockable to an upper face of a joint part 14 of the columnar support 11A. The lock device 23 comprises a pair of yoke beams 70 which are movable along a lower face of the crane installation floor 20, and opening/closing mechanisms 71A, 71B which move to a direction in which a pair of the yoke beams 70 approximate each other or separate from each other.SELECTED DRAWING: Figure 7
【課題】施工費用を低減できる既存構造物の解体方法を提供すること。【解決手段】解体システム2は、既存建物1の屋上階の上に構築されたクレーン設置床20と、クレーン設置床20を支持する既存柱11である支持柱11Aと、クレーン設置床20上に設置されたクレーン21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22と、クレーン設置床20に設けられて支持柱11Aの継手部14の上面に係止可能な係止装置23と、を備える。係止装置23は、クレーン設置床20の下面に沿って移動可能な一対のかんぬき梁70と、一対のかんぬき梁70同士を接近あるいは離間させる方向に移動する開閉機構71A、71Bと、を備える。【選択図】図7
