High-altitude segmented installation construction method for large-span overhanging type multi-layer truss
The invention relates to the field of building construction, in particular to a high-altitude segmented installation and construction method for a large-span overhanging type multi-layer truss. The high-altitude segmented installation construction method for the large-span overhanging type multi-layer truss comprises the following steps that a crawling ladder is arranged beside a truss body pre-buried connecting joint of a building structure, a hanging basket is manufactured at the connecting position of an overhanging beam, and an all-round scaffold is erected; the large-span overhanging type multi-layer truss is divided into multiple trusses in the length direction, the trusses are sequentially installed from one end to the other end in the length direction when the large-span overhanging type multi-layer truss is installed, and the truss structures of all layers are sequentially installed from bottom to top when the trusses are installed. When each layer of truss structure is installed, truss beams are sequentially installed in the direction from the position close to the building structure to the position away from the building structure; and the all-round scaffold, the crawling ladder and the hanging basket are unloaded and dismantled. According to the high-altitude segmented installation construction method for the large-span overhanging type multi-layer truss, installation is conducted in a segmented, layered and fragmented mode, the hoisting weight of a steel structure can be effectively reduced, and therefore potential safety hazards caused by large component loads are reduced.
一种大跨度悬挑式多层桁架高空分段安装施工方法，涉及建筑施工领域。大跨度悬挑式多层桁架高空分段安装施工方法包括以下步骤：在建筑结构的桁架主体预埋连接节点旁设置爬梯，在悬挑梁连接处制作挂篮，搭设满堂脚手架；将大跨度悬挑式多层桁架沿长度方向分成多榀桁架，安装大跨度悬挑式多层桁架时沿长度方向从一端到另一端依次安装各榀桁架，安装每榀桁架时从下至上依次安装每层桁架结构，安装每层桁架结构时从靠近建筑结构到远离建筑结构方向依次安装各根桁架梁；卸载并拆除满堂脚手架、爬梯和挂篮。大跨度悬挑式多层桁架高空分段安装施工方法通过分段、分层、分片进行安装，能够有效减轻钢结构的吊装重量从而减少因构件荷载较大造成的安全隐患。
