Bridge span structure
The invention relates to a bridge span structure. The bridge span structure comprises chord members, bearing cables, web members and bridge deck beams. The chord members are connected with the bearing cables through web members, and the chord members are connected with bridge deck beams laid on the bearing cables through web members. The bearing cables are divided into two groups and are arranged in a herringbone or H shape on a plane; the bridge floor beams form two herringbone or H-shaped parallel pedestrian passageways, the middle of a span is low, and the two ends of the span are high; the chord members and the load-bearing cables are in a vertically crossed spatial relationship; the bearing cable is in a concave shape; and the chord member is in an upward arch shape. Compared with the prior art, when the bridge span structure is applied to a bridge, the advantage of force transmission of the space structure of the bridge span structure can be brought into full play, a lighter building form, higher economical efficiency and structural stability are obtained, meanwhile, higher traffic capacity is brought, and the bridge span structure is economical, efficient, attractive and practical.
本发明涉及一种桥跨结构，所述桥跨结构包括弦杆、承重索、腹杆和桥面梁；所述弦杆由腹杆将其与承重索连接，所述弦杆由腹杆将其与铺设于承重索上的桥面梁连接。所述承重索分为两组，在平面上构成“人”字形或“H”形的布置；所述桥面梁构成“人”字形或“H”形的两条并列行人通道，跨中低，两端高；所述弦杆和承重索呈现竖向交叉的空间关系；所述承重索为下凹的形态；所述弦杆为上拱的形态。与现有技术相比，本发明的桥跨结构应用于桥梁中时，可以充分发挥其空间结构传力的优势，获得更轻盈的建筑形态，更高的经济性和结构稳定性，同时带来更高的交通通行能力，经济高效、美观实用。
