该文对斜拉索传统撑脚设计理念进行改进,提出了一种大吨位的张拉撑脚装置;通过撑脚设计和结构验算方式验证了该装置的可行性。该撑脚装置具有适用性强、结构轻巧、操作方便、轻便和稳定性好的特点,不仅满足在不中断桥面交通条件下快速地安装与更换斜拉索的作业要求,也为斜拉索张拉的标准化作业提供了设备支持。 This paper improves the traditional design concept of stay cables, and proposes a large-tonnage tension stay device. The feasibility of the device is verified by foot design and structural checking. The strut device has the characteristics of strong adaptability, light weight, convenient operation, light weight and good stability, which not only meets the requirements of quickly installing and replacing the stay cables without interrupting the traffic conditions of the bridge deck, Tensioned standardization provides device support.
