Assembled steel truss tied-arch bridge
The invention discloses an assembled steel truss tied-arch bridge. The assembled steel truss tied-arch bridge comprises an underframe and an arch frame; at least one hanging rod is arranged between the bottom frame and the arch frame, and the hanging rods are perpendicular to the bottom frame; the bottom frame comprises side supports and a bottom plate, and the two ends of the bottom plate are connected with the side supports; each side support comprises double layers of truss pieces, a supporting piece is arranged between the double layers of truss pieces, and the two sides of the supportingpiece are connected with the truss pieces; the bottom plate comprises a plurality of cross beams, and the two ends of each cross beam are connected with the side faces, close to the bottom, of the truss pieces; and a clamping piece is arranged at one end of the truss piece. The internal structure of the truss pieces is optimized, the size and the quality are optimized, the individual soldier transportation combat capability is improved, the troop spanning capability is improved, and the bearing capability of the beam bridge is greatly improved; and by arranging the tensioning rods, after the truss pieces are fixed through the bolts, the tensioning rods are screwed down, the connecting stability between the truss pieces is improved, and the connecting strength is improved.
本发明公开了一种装配式钢桁架系杆拱桥；包括底架、拱架；所述底架与拱架之间至少设有一根吊杆，所述吊杆与底架垂直设置；所述底架包括侧撑和底板，所述底板的两端均连接有侧撑；所述侧撑包括双层桁架片，双层桁架片之间设有支撑片，所述支撑片两侧均与桁架片连接；所述底板包括多根横梁，所述横梁的两端与桁架片靠近底部的侧面连接；所述桁架片的一端设有夹持件；优化桁架片内部结构，优化尺寸和质量，增加单兵运输作战能力，增加部队跨越能力，大大提高了梁式桥的承载能力；通过设置拉紧杆，在桁架片通过螺栓固定好之后，拧紧拉紧杆，提升桁架片之间连接的稳定性，提升连接强度。
