The key manufacturing technology of steel anchor beams of long-span steel-concrete composite cable-stayed bridges
Combining with the steel anchor beam structure of large-span steel-concrete composite cable-stayed bridge pro-duced and manufactured by the company in recent years,taking Yumenkou Yellow River Bridge as an example,this paper introduces the composition of steel anchor beam structure,analyzes the key and difficult points of steel anchor beam manu-facturing of large-span steel-concrete composite cable-stayed bridge,and discusses the key manufacturing technologies of steel anchor beams of long-span steel-concrete composite cable-stayed bridges in view of the complex structure and multiple fusion welds characteristic of steel anchor beam in this project,it solves the welding deformation,dimensional accuracy control and other many technical problems in the processing and manufacturing process.
