摘要
针对高层建筑建造中普遍应用的型钢悬挑脚手架设计与施工,分析了型钢悬挑梁的设计计算模型,基于算例结果提出了模型参数的取值标准;建立了U形拉环在混凝土楼板上锚固破坏的三棱柱体模型,给出了锚固承载力的设计计算方法;总结了斜拉钢丝绳在实际工程应用中的缺陷,建议取消斜拉钢丝绳。
Aiming at the design and construction of section steel cantilever scaffolds that are widely used in high-rise building construction,the design calculation model for section steel cantilever beams is analyzed,and the valuing standard of model parameters are proposed based on calculation results.A triangular prism model was developed to study the anchor damage of the U-type pull ring on a concrete floor,and a design calculation method for anchor bearing capacity is provided.Defects in engineering applications of cable-stayed wire ropes are summarized.It is recommended to cancel cable-stayed wire ropes.
