Large-span steel structure roof hoisting construction method
The invention relates to the technical field of steel structure roof construction, and provides a hoisting construction method for a large-span steel structure roof. The main trusses are attached to the temporary supporting columns, and truss sections of the main trusses are assembled on a pre-assembling platform; integrally hoisting the first main truss on the pre-assembly platform to the main body structure by using a crawler crane; supporting the first main truss by using an inclined temporary supporting piece connected with the main body structure; and the crawler crane and the tower crane are used for alternately hoisting the next primary truss and the next secondary truss till all the primary trusses and all the secondary trusses of the steel structure roof are hoisted to the main body structure. The construction efficiency is improved, the high-altitude operation amount of workers is reduced, and the safety risk is greatly reduced.
本申请涉及钢结构屋面施工技术领域，提供了一种大跨度钢结构屋面吊装施工方法，对地面进行土质替换处理；依附于所述临时支柱，在预拼装平台上进行每个主桁架的桁架段的拼装；利用履带吊将预拼装平台上的第一榀主桁架整体吊装至主体结构上；利用与主体结构连接的斜向临时支撑件支撑第一榀主桁架；利用履带吊和塔式起重机交替进行下一榀主桁架和次桁架的吊装，直至钢结构屋面的全部主桁架和次桁架吊装至主体结构上。本发明提高了施工效率，减少了工人高空作业量，极大的降低了安全风险。
