高空大悬挑结构的模架设计与施工
|
摘要
通过上海青浦建设工程质量检测中心迁建业务用房工程的施工实践,详细介绍了利用型钢悬挑支撑系统搭设高空大悬挑结构的支模架、防护脚手架的施工技术。针对高空大悬挑结构的特点,分别对支撑系统方案设计、受力分析、施工方法、安全保证措施等进行了阐述。工程实践证明,该施工工艺具有就地取材、操作简单、安全可靠、成本低廉等优点,可供参考。
Based on the relocation construction practice of the service building of Shanghai Qingpu Construction Quality Inspection Center,the construction technology of formwork support and protective scaffolding for large suspended structure at high altitude using section steel suspended support system is introduced in detail.According to the characteristics of the suspended structure at high altitude,the scheme design,stress analysis,construction method and safety assurance measures and so on are expounded respectively for the support system.The engineering practice proves that the construction technology has the advantages of local material acquisition,simple operation,safety and reliability,low cost,and so on,which can be used for reference.
