普通钢丝绳的固有结构 ,导致其非弹性变形很大 ,且难以控制。在悬索桥吊索长度精度要求非常高的情况下 ,如何有效地控制钢丝绳的非弹性变形就成了钢丝绳吊索制作的关键技术。本文介绍了国内首次对钢丝绳的桥用工艺特性进行全面探索及工艺试验的成果 ,论述了有效控制钢丝绳非弹性变形的方法 ,并结合广东虎门大桥钢丝绳吊索制作任务 ,对研制开发的钢丝绳吊索高精度制作工艺作了全面的介绍。该项研究成果在广东虎门大桥钢丝绳吊索安装时全桥未用一块垫片 ,一步安装到位 ,实现了钢梁的无调整安装 ,给主桥钢箱梁吊装带来了极大的方便。
The inherent structure of ordinary wire rope, leading to its large non-elastic deformation, and difficult to control. How to effectively control the inelastic deformation of steel wire ropes has become the key technology in the manufacture of steel wire rope slings. This paper introduces the first comprehensive exploration of the process characteristics of the bridge with steel wire rope and the results of the technological test. The method of effectively controlling the inelastic deformation of the steel wire rope is discussed. Combined with the task of making the steel wire rope sling of Humen Bridge in Guangdong, the research and development of the wire rope sling High-precision manufacturing process made a comprehensive introduction. The research results in the installation of steel wire rope slings in Humen Bridge in Guangdong without a gasket, one-step installation in place to achieve the adjustment of the installation of steel beams, lifting the main bridge to bring a great steel girder convenience.
