Manufacturing method of double-anchor box type external node chord member

The invention relates to a manufacturing method of a double-anchor box type external node chord member. The double-anchor box type external node chord member is manufactured according to the steps of S1) blanking, S2) machining, S3) flat plate drilling, S4) web receiving and machining, S5) plate unit assembly welding and S6) chord member assembly welding. As nodes are mounted out of anchor boxes connected with stay cables on the chord member to avoid from the connecting places between the anchor boxes and the stay cables, the anchor boxes cannot be interfered with the nodes, the installation of the stay cables of a bridge and the welding of node plates are not mutually interfered, and the construction progress of the bridge is guaranteed. 本发明涉及一种双锚箱式体外节点弦杆制作方法，该双锚箱式体外节点弦杆按照S1.下料；S2.机加工；S3.平板钻孔；S4.腹板接料、机加工；S5.组焊板单元；S6.弦杆组焊；通过在弦杆上与斜拉索相连接的锚箱体外安装节点，避开了锚箱与斜拉索相连接处，能够让锚箱与节点不产生干涉，从而使得桥梁的斜拉索安装与节点板的焊接相互之间不干扰，保证了桥梁的施工进度。
