摘　　要：针对传统装配式支吊架托臂固定无法调节导致空间利用率低的问题,提出了一种新型可调节托臂的支吊架.设计了该新型可调节托臂支吊架的构造,分析了其工作原理及优点,并进行了模型实验和有限元数值模拟研究.研究结果表明,所提出和设计的新型可调节托臂支吊架结构具有良好的承载能力,满足工程最大位移和容许应力的要求,极限荷载作用下的失效模式是主横担螺栓孔发生局部破坏.Aiming at the problem that the traditional assembly support boom cannot be adjusted,which leads to low space utilization rate,a new adjustable support boom is proposed.The structure of the new adjustable bracket is designed,and its working principle and advantages are analyzed.The model experiment and finite element numerical simulation are carried out.The research results show that the proposed and designed new adjustable boom support and hanger structure has good bearing capacity,which meets the requirements of maximum displacement and allowable stress of practical project.The failure mode under ultimate load is the local failure at the bolt hole of the main cross arm.
