Method for dismantling high-rise building structure
The invention relates to the technical field of flue gas dismantling, and discloses a high-rise building dismantling method which comprises the following steps: S10, derrick assembly: firstly, a derrick foundation is built, the derrick is formed by connecting vertical rods, angle steel and cross rods through bolts, the derrick is installed after construction is completed, and equipment in a building is cleaned after installation; hoisting the mounted derrick into a building structure; 12 steel channel radiation beams are used as main beams, an inner hanging bracket and an outer hanging bracket are hung on the radiation main beams, double-layer safety protection is conducted on the periphery of the radiation main beams through a safety net and a closed net, and during installation, according to the installation sequence of installation of inner and outer bearing steel rings and the radiation main beams, then installation of square timbers, wood plate laying, the safety net and the inner and outer hanging brackets, the operation platform is installed; and the whole body is sleeved outside the derrick. The perpendicularity and stability of the derrick in the dismantling process are ensured, the risk of high-altitude operation is reduced, and falling and fire accidents possibly occurring in the construction process are prevented.
本发明涉及烟气拆除技术领域，公开了一种高耸建构筑物拆除方法，包括以下步骤：S10、井架组装：首先进行井架基础搭建，井架为立杆、角钢、横杆，通过螺栓相连接，在施工完成后再进行井架安装，安装后再对建构筑物内部设备进行清场，并将安装后的井架吊装进建构筑物内；S20、安装拆除操作平台：使用12根槽钢辐射梁作为主梁，并将内外吊架悬挂在辐射主梁上，周围采用安全网以及密闭网进行双层安全防护，安装时按照安装内外承重钢圈，辐射钢梁，再安装方木、铺木板、安全网及内外吊架的安装顺序，整体套设在井架外。确保了拆除过程中井架的垂直和稳定，降低了高空作业的风险，预防了施工过程中可能发生的坠落和火灾事故。
