摘　　要：近20年来随着建筑功能和使用要求的提高,大跨度大面积重荷载的高空连廊不断出现,传统的施工方法难以适应,考虑实际工程特点,优化选择使用空间桁架钢平台进行高空连廊的搭建。由于施工场地的限制和起重机械的缺少,采用整体提升法进行钢平台的提升,并对提升吊点的选择布置、提升位移差、提升稳定性进行分析和总结。The last two decades,with the improvement of building function and use requirement,the traditional construction method is difficult to adapt to the large span and large area and heavy load air corridor. In this paper,considering technical application practice of engineering,optimizing selection of space truss steel platform is made to build corridor. Integral lifting method is adopted to install the steel platform due to the limitation of construction site and hoisting machinery. This paper analyzes and summarizes the layout of the lifting point,the displacement difference and the stability about lifting process.
