Assembly type aluminum alloy prestress truss bridge
The invention relates to the technical field of bridge structures, in particular to an assembled aluminum alloy prestressed truss bridge. The two sets of main truss girder piece assemblies, the multiple large cross beam pieces, the multiple small cross beam pieces and the multiple longitudinal beams are all made of aluminum alloy materials, the two sets of main truss girder piece assemblies are arranged in parallel at intervals, and the multiple large cross beam pieces, the multiple small cross beam pieces and the multiple longitudinal beams are all arranged between the two sets of main trussgirder piece assemblies. Prestressed inhaul cable assemblies are arranged on the faces, away from each other, of the two large cross beam pieces located at the two ends of the two sets of main truss beam piece assemblies. The invention has the beneficial effects that a series of problems of field processing are reduced, the construction is convenient, and modular assembly and molding are realized;the aluminum alloy truss and the prestress inhaul cable assembly cooperate to bear force, on one hand, a lower chord of a bridge is helped to be resisted against tension, more of the bridge is tensioned, the rigidity of the bridge is improved, the problems that an aluminum alloy bridge is insufficient in rigidity and a bridge body slightly shakes are solved, and the pedestrian bridge passing comfort is improved.
本发明涉及桥梁构造技术领域，尤其涉及一种装配式铝合金预应力桁架桥，两组主桁架梁片组件、多个大横梁片、多个小横梁片和多个纵梁均为铝合金材质，两组所述主桁架梁片组件平行且间隔设置，多个所述大横梁片、多个所述小横梁片以及多个所述纵梁均设在两组所述主桁架梁片组件之间；位于两组所述主桁架梁片组件两端的两个大横梁片相互远离的一面上均设置有预应力拉索组件。本发明的有益效果是：本发明减少了现场加工的一系列问题，施工便捷，模块化拼装成型；铝合金桁架和预应力拉索组件合作受力，一方面帮助抵抗桥梁的下弦杆受拉，更多的是拉紧桥梁，使桥梁刚度提高，解决铝合金桥梁刚度不足，桥体轻微晃动问题，提高行人桥梁通行舒适性。
