Novel anchor box type cable beam anchoring structure of steel truss girder cable-stayed bridge
The invention relates to the technical field of cable beam anchoring, and discloses a novel anchor box type cable beam anchoring structure of a steel truss girder cable-stayed bridge. A steel anchor box comprises a bearing plate perpendicularly welded to a gusset plate, an upper shear plate fixedly welded to the gusset plate is perpendicularly welded to one side of the bearing plate, and a lower shear plate fixedly welded to the gusset plate is perpendicularly welded to the other side of the bearing plate; the novel anchor box type cable beam anchoring structure of the steel truss girder cable-stayed bridge is characterized in that the upper shear plate is vertically welded to one side of the bearing plate, the lower shear plate fixedly welded to the gusset plate is vertically welded to one side of the bearing plate, and the inner side stiffening plate is fixedly welded between the upper shear plate and the lower shear plate. The two inner shear plates are arranged in the cavity structure formed by the bearing plate, the inner side stiffening plate, the upper shear plate and the lower shear plate and bear shear force together with the upper shear plate and the lower shear plate, and the problem that the stress level of weld joints of the shear plates is too high can also be effectively solved. And secondly, according to the scheme, the welding seam bending supporting points of the bearing plate are increased, so that the welding seam stress level of the bearing plate is reduced.
本发明涉及索梁锚固技术领域，且公开了一种钢桁梁斜拉桥新型锚箱式索梁锚固结构，所述钢锚箱包括与节点板垂直焊接的承压板，所述承压板的一侧垂直焊接有与节点板固定焊接的上剪力板，所述承压板的一侧垂直焊接有与节点板固定焊接的下剪力板，所述上剪力板与下剪力板之间固定焊接有内侧加劲板，该一种钢桁梁斜拉桥新型锚箱式索梁锚固结构,通过在承压板、内侧加劲板、上剪力板、下剪力板形成的空腔结构布置了两块内剪力板，与上剪力板和下剪力板共同承受剪力，同样能有效解决剪力板焊缝应力水平过高的问题。其次，该方案增加了承压板的焊缝受弯支撑点，从而减小承压板的焊缝应力水平。
