摘　　要：扣件式钢管模板支架是分析高支模施工坍塌事故时有发生的一个重要内容。模板支架属于钢结构范畴,扣件式钢管模板支架对其失稳模式有着重要的影响。通过对扣件式钢管模板支撑开展一系列的试验和理论研究,得到不同工况下模板支架的极限承载力,并根据对计算数据的分析提出了高大模板支撑架整体坍塌的应用技术措施。Fastener- style steel pipe falsework is an important content of collapse accidents occurrence of the analysis on the construction of high formwork. The template bracket belongs to the category of steel structure,and fastener- style steel pipe falsework has the important influence on the buckling mode. By carrying out a series of experimental and theoretical studies of fastener style steel pipe formwork support,the ultimate bearing capacity of formwork support under different conditions is obtained,and application technical measures of collapse of whole on the tall formwork support frame is put forward according to the analysis of calculated data.
