Tower section structure of upper tower of cable-stayed bridge and processing method of tower section structure
The invention discloses a cable-stayed bridge upper tower section structure and a processing method thereof.The upper tower section comprises side wall plates, corner wall plates and stiffening rib plates, and the side wall plates and the corner wall plates are sequentially and alternately connected to define a uniform-section rectangular column structure with a concave-angle section; the stiffening rib plates are arranged on the inner side faces of the side wall plates in the height direction of the upper tower section, and a plurality of stiffening rib plates are arranged on each side wall plate at equal intervals. A plurality of net-shaped through holes are evenly formed in one end or two ends of the side wall plates, the corner wall plates and the stiffening rib plates in the thickness direction. The steel cable tower section structure convenient to construct is designed and is produced by adopting a targeted process, and welding deformation is controlled and prevented by adopting the combination of constraint and self-constraint, rigid constraint and flexible constraint, pre-deformation and reserved proper welding adjustment shrinkage from the plate unit; the end face of the steel pylon is subjected to finish machining, and it is guaranteed that the segment end face machining precision meets the design requirement.
本发明公开一种斜拉桥上塔塔节结构及其加工方法，所述上塔塔节包括侧壁板、角部壁板和加劲肋板，所述侧壁板与所述角部壁板依次相间连接围构成等截面矩形带凹角截面的柱体结构，所述加劲肋板沿所述上塔塔节的高度方向设置在侧壁板的内侧面上，每块所述侧壁板上等间距设置若干块所述加劲肋板；所述侧壁板、角部壁板和加劲肋板的一端或者两端沿厚度方向均匀设置有若干网状通孔。本发明设计的一种便于施工的钢索塔塔节结构，并采用针对性的工艺进行生产，通过从板单元开始，采用它约束和自约束、刚性约束和柔性约束形相结合、预变形以及预留合适的焊调收缩量来控制和预防焊接变形；对于钢索塔端面进行精加工处理，保证节段端面加工精度达到设计要求。
