Steel bridge tower-composite structure bridge tower transition section structure and construction method
The invention discloses a steel bridge tower-combined structure bridge tower transition section structure and a construction method. The structure comprises an upper tower column of a steel structure, a lower tower column of a steel-concrete combined structure, a middle tower column, a pressure-bearing steel plate and stiffening ribs. The middle tower column comprises a transition section outer wall plate arranged on the periphery, a transition section inner wall plate arranged on the inner ring and transition section stiffening ribs. The transition section inner wall plates are separated into a plurality of cells through transition section steel partition plates, and the cells are filled with concrete. The middle tower column is divided into a first transition section and a second transition section, the cross section of the first transition section is not changed in the vertical direction and is matched with the cross section of the bottom of the upper tower column, and the inner ring of the cross section of the second transition section is gradually expanded in the vertical direction and is matched with the cross section of the lower tower column until reaching the bottom. According to the transition section structure, through the gradual change cross section structure of the middle tower column, connection of the steel bridge tower and the steel-concrete combined structure bridge tower is achieved, the structure stress is reasonable, and the force transmission path is clear.
本发明公开了一种钢桥塔‑组合结构桥塔过渡段构造及施工方法，该构造包括钢结构的上塔柱，钢‑混凝土组合结构的下塔柱，中塔柱，承压钢板及加劲肋。中塔柱包括设于外周的过渡段外壁板，设于内圈的过渡段内壁板，以及过渡段加劲肋。所述过渡段内壁板之间通过设有过渡段钢隔板隔离成多个格室，格室内填充有混凝土。中塔柱分为第一过渡段和第二过渡段，第一过渡段横截面在竖直方向不变，与上塔柱底部横截面相适配，第二过渡段横截面的内圈在竖直方向上逐渐扩大，直至到达底部时与下塔柱横截面向适配。本发明的过渡段构造，通过中塔柱的渐变横截面构造，实现了实现钢桥塔和钢‑混凝土组合结构桥塔的连接，结构受力合理、传力路径明确。
