摘要
高层建筑花篮拉杆悬挑式脚手架应用较为广泛,但其承载力的安全性是目前研究的重点.为探究脚手架的承载能力及其内力情况,采用结构验算及试验检测的方法对设计的花篮拉杆悬挑式脚手架的承载力进行了计算分析,并对其部件的抗拉及抗剪能力进行安全性能验证,结果表明脚手架各组成部分的承载力计算结果均满足规范要求,部件的抗拉和抗剪能力经检验,均满足技术要求,悬挑架的轴力、剪力和弯矩波动范围分别为-13.4 kN~30.8 kN、-15 kN~20 kN和-5 kN·m~25 kN·m,研究成果可为同类型的脚手架工程的设计和搭建提供参考.
The flower basket tie rod cantilevered scaffolding for high-rise buildings is widely used,but the safety of its bearing capacity is the focus of current research.In order to explore the bearing capacity of scaffolding and its internal force,the bearing capacity of the flower basket tie rod cantilevered scaffold was calculated and analyzed by the method of structural verification and test testing,and the tensile and shear resistance of its components were verified by safety performance,and the results showed that the bearing capacity calculation results of each component of the scaffolding met the requirements of the specification,and the tensile and shear resistance of the components were inspected and met the relevant technical requirements,and the axial force,shear force and bending moment fluctuation range of the cantilevered frame were-13.4 kN~30.8 kN and-15 kN,respectively 20 kN and-5 kN·m~25 kN·m,the research results can provide reference for the design and construction of the same type of scaffolding project.
