Steel truss stiffening large-span vacuum tube beam
The invention provides a steel truss stiffening large-span vacuum tube beam. The steel truss stiffening large-span vacuum tube beam comprises an n-shaped tube, a U-shaped beam, two rows of stiffening main trusses and a plurality of flat connecting rods. The n-shaped pipe is fixed to the top end of the U-shaped beam, and a pipeline in the extending direction of the bridge is formed between the n-shaped pipe and the U-shaped beam. The two rows of stiffening main trusses are arranged on the midspan section of the vacuum tube beam and located on the two sides of the n-shaped tube respectively, and the bottom ends of the stiffening main trusses are fixed to the top of the U-shaped beam. The plurality of parallel connecting rods are arranged right above the n-shaped pipe at intervals in the extending direction of the bridge, and the two ends of each parallel connecting rod are connected to the two rows of stiffening main trusses respectively. The span of the vacuum tube beam can be prolonged, the spanning capacity of the vacuum tube beam is improved, and therefore the requirement of development of an ultra-high-speed low-vacuum pipeline maglev transportation system in the future for a large-span bridge is met.
本发明提供了一种钢桁加劲大跨度真空管梁，包括：n型管、U型梁、两排加劲主桁和多根平联杆；所述n型管固定在U型梁的顶端，n型管和U型梁之间形成沿桥梁延伸方向的管道；所述两排加劲主桁设置于真空管梁的中跨段，并分别位于n型管的两侧，加劲主桁的底端固定在U型梁的顶部；所述多根平联杆沿桥梁延伸方向间隔设置在n型管的正上方，且每根平联杆的两端分别连接在两排加劲主桁上。应用本发明可以延长真空管梁的跨度，提高真空管梁的跨越能力，从而满足未来超高速低真空管道磁浮交通系统发展对大跨度桥梁的需求。
