Large-span flying wing type steel box arch bridge
The invention provides a large-span flying wing type steel box arch bridge. The bridge comprises a left main arch rib, a right main arch rib, a left auxiliary arch rib, a right auxiliary arch rib, steel box girders, opposite pull rods and a force transmission device. The left main arch rib and the right main arch rib are fixedly arranged on an arch support and are arranged in a bilateral symmetrymode. The spans of the left auxiliary arch rib and the right auxiliary arch rib are greater than those of the left main arch rib and the right main arch rib; the left auxiliary arch rib is arranged inthe inner side of the left main arch rib; the right auxiliary arch rib is arranged in the inner side of the right main arch rib; the left auxiliary arch rib and the right auxiliary arch rib are respectively and fixedly arranged on the arch support in the bilateral symmetry manner; a plurality of steel box girders are arranged between the left auxiliary arch rib and the right auxiliary arch rib and connected side by side to form a bridge body, the two ends of each steel box girder are connected with a main arch through force transmission devices respectively, a plurality of pairs of pull rodsare arranged between the left main arch rib and the left auxiliary arch rib, and a plurality of pairs of pull rods are arranged between the right main arch rib and the right auxiliary arch rib. The technical problem that all parts of the large-span flying wing type steel box arch bridge are too heavy in structural weight and inconvenient to transport can be solved.
本发明提供一种大跨飞翼式钢箱拱桥，包括左侧主拱肋、右侧主拱肋、左侧副拱肋、右侧副拱肋、钢箱梁、对拉杆以及传力装置，左侧主拱肋与述右侧主拱肋分别固定设于拱座上且左右对称设置，左侧副拱肋和右侧副拱肋的跨径大于左侧主拱肋和右侧主拱肋的跨径，左侧主拱肋的内侧设有左侧副拱肋，右侧主拱肋的内侧设有右侧副拱肋，左侧副拱肋与述右侧副拱肋分别固定设于拱座上且左右对称设置，左侧副拱肋与右侧副拱肋之间设有钢箱梁，若干钢箱梁并排连接构成桥体，钢箱梁的两端分别通过传力装置连接主拱，左侧主拱肋与左侧副拱肋之间设有若干对拉杆，右侧主拱肋与右侧副拱肋之间设有若干对拉杆。可解决大跨飞翼式钢箱拱桥的各部分结构重量过重而不便于运输的技术问题。
