Construction method of oversized cantilever steel structure
The invention discloses a super-large cantilever steel structure construction method, which comprises construction simulation analysis, support steel pipe installation and correction, large cantilever structure installation and temporary support removal, and the construction simulation analysis comprises stress analysis, support steel pipe specification, support steel pipe stress and deformation in each stage, large cantilever structure deformation during support removal and other data; after the steel structure is installed, the temporary supporting devices are dismantled layer by layer from top to bottom, the deformation condition of the cantilever structure is observed, the total deformation of the cantilever structure is observed and compared with construction simulation analysis data, and after safety is determined, the supporting steel pipe is dismantled by adjusting the position of an end cover plate, increasing the distance between the supporting upper structure and the large cantilever steel structure and utilizing a tower crane. According to the construction method for the oversized cantilever steel structure, through the arrangement of the supporting device and the driving hydraulic rod, after construction of the upper structure is completed, it is guaranteed that stress conversion of the oversized cantilever structure is stable by removing the mounting plate step by step, and processing can be conducted in time when errors occur.
本发明公开了一种超大悬挑钢结构施工方法，包括施工模拟分析、支撑钢管安装和校正、安装大悬挑结构和临时支撑拆除，所述施工模拟分析包括受力分析、支撑钢管规格、各阶段支撑钢管应力及变形、拆除支撑时大悬挑结构变形等数据；所述钢结构安装完成后，自上而下逐层拆除临时支撑装置，观察悬挑结构变形情况，观察悬挑结构总变形并与施工模拟分析数据比对，确定安全后，通过调整端部盖板位置，增加支撑上部结构与大悬挑钢结构距离，利用塔吊拆卸支撑钢管；本发明提出的一种超大悬挑钢结构施工方法主要是通过支撑装置以及驱动液压杆的设置，使上部结构施工完毕后，通过逐步移除安装板，确保大悬挑结构受力转换平稳，并且发生错误时能及时进行处理。
