组合式悬挑脚手架在高层建筑施工中的应用

Application of Combined Cantilever Scaffold to High-Rise Building Construction

结合苏州市工业园区一高层建筑施工实例,介绍了组合式悬挑脚手架的布置方案以及受力特点。设计时,利用有限元分析软件Midas和Abaqus对其型钢梁构件和锚支座分别进行受力分析,研究了跨度、悬挑长度、悬挑梁截面、拉杆水平角度等因素对悬挑式脚手架受力性能的影响。研究结论可供同类工程参考。

Based on the construction example of a high-rise building in Suzhou Industrial Park,the layout scheme and stress characteristics of the combined cantilever scaffold are introduced is this paper.During the design process,the finite element analysis software Midas and Abaqus were used to analyze the force of the structural steel beam members and anchor supports respectively.The influences of span,cantilever length,cantilever beam section,horizontal angle of the pull rod and other factors on the mechanical performance of cantilevered scaffold were studied.The conclusion can be used as a reference for similar projects.
