Arch bridge steel longitudinal and transverse beam system
The invention provides an arch bridge steel longitudinal and transverse beam system, which comprises steel beams arranged in an arch bridge deck, wherein the steel beams comprise a plurality of rows of steel cross beams and a plurality of rows of steel longitudinal beams; the steel cross beams comprise secondary cross beams, end cross beams, buttress cross beams and suspender cross beams, the strength of the secondary cross beams, the strength of the end cross beams, the strength of the buttress cross beams and the strength of the suspender cross beams are sequentially increased, the suspendercross beams are used for being connected with suspenders of an arch bridge, the buttress cross beams are used for being connected with buttress of the arch bridge, the end cross beams are arranged atthe end parts of the bridge deck in the longitudinal direction, and the secondary cross beams are arranged between the adjacent two rows of buttress cross beams; the steel longitudinal beams compriseside longitudinal beams arranged at the transverse end parts of the bridge deck and a middle longitudinal beam arranged in the transverse middle of the bridge deck, and the strength of the side longitudinal beams is greater than that of the middle longitudinal beam. In the arch bridge steel longitudinal and transverse beam system provided by the invention, the strength of each steel cross beam and each steel longitudinal beam is set according to the application and stress requirements, and on the premise of ensuring that the whole structure has high strength, the steel beam can be integrallyand flexibly split into a plurality of modules for construction, so that the construction difficulty is reduced, and the construction efficiency is improved.
本发明提供一种拱桥钢纵横梁系统，包括用于设置于拱桥桥面内的钢梁，所述钢梁包括多排钢横梁和多排钢纵梁；所述钢横梁包括强度依次增大的次横梁、端横梁、支墩横梁和吊杆横梁，所述吊杆横梁用于与拱桥的吊杆连接，所述支墩横梁用于与拱桥的支墩连接，所述端横梁设于桥面纵向的端部，所述次横梁设于相邻两排所述支墩横梁之间；所述钢纵梁包括设于桥面横向端部的边纵梁和设于桥面横向中部的中纵梁，所述边纵梁的强度大于所述中纵梁的强度。本发明提供的拱桥钢纵横梁系统中，各钢横梁和钢纵梁的强度根据其用途和受力需求设置，在确保整体结构具备较高强度的前提下，可将钢梁整体灵活地拆分成多个模块进行施工，降低施工难度，提高施工效率。
