Steel box arch rib cross node structure of large-span half-through steel box tied arch bridge
The invention discloses a steel box arch rib cross node structure of a large-span half-through steel box tied arch bridge, which comprises a steel box arch rib cross node which is integrally distributed in an X shape, and the steel box arch rib cross node is formed by welding two symmetrically distributed steel box arch rib sections in a cross manner at an acute included angle; the steel box arch rib sections are of a hexagonal special-shaped section hollow steel box arch rib structure. Each steel box arch rib section comprises an arch rib top plate, an arch rib bottom plate and two arch rib web plates, and each arch rib web plate comprises an upper web plate and a lower web plate which are distributed and connected at an obtuse angle; the arch rib top plates of the two steel box arch rib sections share a top plate distributed in an X shape, and the arch rib bottom plates of the two steel box arch rib sections share a bottom plate distributed in an X shape. According to the large-span space steel box arch rib, the problems of uneven stress and insufficient strength and stability due to the fact that the top plate and the bottom plate of two arch ribs are difficult to share the same plane at the intersection node of the large-span space steel box arch rib are solved, and the node is simple in structure, easy to manufacture and install and easy to firmly weld.
本发明公开了一种大跨度中承式钢箱系杆拱桥的钢箱拱肋交叉节点结构，包括整体呈X型分布的钢箱拱肋交叉节点，钢箱拱肋交叉节点由两个对称分布的钢箱拱肋节段呈锐角夹角交叉焊接形成，钢箱拱肋节段采用六边形异形截面中空钢箱拱肋结构；钢箱拱肋节段包括拱肋顶板、拱肋底板和两个拱肋腹板，拱肋腹板包括呈钝角夹角分布连接的上腹板和下腹板；两个钢箱拱肋节段的拱肋顶板共用一个呈X型分布的顶板，两个钢箱拱肋节段的拱肋底板共用一个呈X型分布的底板。本发明解决了大跨径空间钢箱拱肋存在两拱肋的顶底板在相交节点处难以共面而存在受力不均、强度和稳定性不足的问题，且节点构造简单，易于制作安装且容易牢固焊接。
