Box and truss composite node structure of steel box and truss composite bridge
The invention relates to a box and truss composite node structure of a steel box and truss composite bridge. A web member inside connecting plate and a web member outside connecting plate are arranged on a top plate of a steel box; the web member inside connecting plate is aligned to and welded with a steel box inner web plate; and an inverted T-shaped rib of the web member outside connecting plate is aligned to and welded with the web member outside connecting plate. A tuyere is arranged on the outer side of the steel box. A plurality of partitions are arranged in the steel box at a node to enhance the rigidity of the node and improve the stressed state of the node. The steel box is internally provided with whole partitions and semi-partitions; manholes are formed in the whole partitions; and a steel anchor box is arranged in the tuyere to facilitate later maintenance. A man hole is formed in a top plate of the tuyere for later overhaul and maintenance of the node. The steel anchor box of a stay cable of a cable-stayed bridge or a suspension cable of a suspension bridge is arranged in the tuyere and welded on a steel box outside web plate. The structure is convenient to construct and definite and reasonable in stress, transfers a force directly, reduces material usage, can ensure construction quality, facilitates later maintenance, and is applicable to a beam bridge, a cable-stayed bridge and a suspension bridge. The Dongting Lake grand bridge as a railway coal transportation corridor from the west Inner Mongolia to the central China employs the structure, and the application effect is good.
