大跨度高支模楼板部分扣件式钢管支撑体系的设计与施工

Design and construction of large-span high formwork floor part of fastener style steel pipe support system

结合吉林省延吉市某高层建筑框剪结构工程,对大跨度高支模扣件式钢管支撑架体系的设计与施工进行了探讨.通过对工程中采用的支撑架体系的强度及稳定性验算分析,给出了大跨度高支模扣件式钢管支撑体系的设计计算方法和施工工艺关键控制点以及施工技术措施.经实践验证,本文方案能够有效克服质量通病,满足工程验收规范与质量评定标准的要求,可供类似工程借鉴.

Combining with a high-rise building frame-shear structure project in Yanji city of Jilin province, the large span high formwork support system of fastener type steel tube will be discussed in this paper. The strength and stability checking of engineering used in support system analysis, control points and technical measures for the construction of key design calculation method and construction technology of large span high formwork structure is given out. The practice proves that this scheme can effectively overcome the quality common diseases, and can meet the requirements of engineering acceptance specification and quality assess- ment standard, which can be used for reference in similar engineering.
