摘要
当模板支架、施工用操作架等脚手架不设连墙杆时,必须首先对脚手架进行抗倾覆验算,然后才是强度、刚度和稳定性计算。而现行的国家标准中没有倾覆验算和稳定性验算内容。根据国家有关标准导出了脚手架倾覆验算公式,并有2个算例辅以说明。最后指出脚手架高宽比与脚手架的倾覆有关,与脚手架稳定性承载能力无关。
When some scaffoldings of formwork support and construction handling frame have no connect wall bars,it must firstly check to calculate overturn of scaffolding,and then calculate strength,rigid and stable. But the present national standards and codes have no related checking calculation contents on overturn and stable of scaffolding. In this article,the author derives overturn calculation formula on scaffolding on the basis of these standards and provides two examples. The author also discusses that width of scaffolding is related to overturn of scaffolding and unrelated to stable of scaffolding.
