基于外脚手架电梯井处半悬挑梁计算研究

Research on calculation of semi-cantilever beam at elevator shaft based on external scaffolding

以某高层商住楼电梯井处外脚手架12根半悬挑梁施工为背景,经分析这12根半悬挑梁只需五种计算模型,选取其中6.3 m长半悬挑主梁L 3为例,进行计算模型、设计参数以及设计验算、工艺流程的分析,未见异常现象,为高层商住楼外脚手架的实际应用积累经验。

Taking the construction of 12 semi-cantilevered scaffolding beams at the elevator shaft of a high-rise commercial and residential building as the background,after analyzing the 12 semi-cantilevered beams,only five calculation models need to be selected,among which the 6.3 m long semi-cantilevered main beam L 3 is selected as an example to carry out the calculation model,design parameters,design checking calculation and process analysis,and no abnormal phenomena are found.The practical application of scaffolding outside residential buildings has accumulated experience.
