摘要
因郑州黄河公铁两用桥主桥边桁下弦杆采用了平行四边形截面整体节点形式,本文介绍了这种平行四边形截面整体节点下弦杆的制造工艺技术,经实践证明可靠实用,对同类型桥梁制造有指导意义。
Lower chord of main bridge fringe truss of Zhengzhou Yellow river highway—railway bridge adopt integral node with parallelogram section,this article describes manufacturing process technology of lower chord of this kind.Practice proves that it is reliable and practical,may have guiding significance for manufacturing of same kinds bridge.
