摘要
针对目前公路桥梁伸缩缝接合件的缺陷,设计了一种Ω型承重封闭式弹性接合件.介绍了其结构组成与工作原理;并在环境温度变化时分析接合件的受力和变形,提出了应力、变形和稳定性的计算方法,为接合件的设计提供了理论依据.
In view of the limitation of the existing highway bridges expansion joint, the structure organization and working principle of the Ω mold spandrel confining elastic junction workpiece are presented in the paper. The phenomenon of accepting force and deformation of the Ω pattern spandrel confining elastic joint workpiece is discussed under the circumstances of the temperature＇ s change . The calculating method for the workpiece＇s stress, stability and deformation is also analysed. The mechanics basis is also given to design the workpiece.
