高大模板支架施工安全技术分析

Analysis on construction safety technology of high supported formwork

高大模板支架倒塌易引起重大人员伤亡,随着高层大跨建筑结构越来越多,高大模板支架应用普遍,其使用安全受到人们关注。通过对历年来全国房屋市政工程生产安全较大及以上事故中支模事故的调查,分析引起高支模倒塌或失稳的主要原因,结合力学分析探讨影响高支模稳定和承载能力的安全技术。所做分析和结论有助于高支模的设计施工安全,预防高支模事故的发生。

Collapse of high supported formwork is easy to cause heavy casualties. With more and more high-rise and long-span building structures,high supported formwork is widely used,and its safety is concerned. Through the investigation of high supported formwork accidents in 2014-2019 national housing and municipal engineering production safety and above accidents,the main causes of collapse or instability of high supported formwork are analyzed. Combined with mechanical analysis,the safety technology affecting the stability and bearing capacity of high supported formwork is studied. The analysis and conclusion are helpful to the design and construction safety of high supported formwork and prevent the occurrence of high supported formwork accidents.
