Bridge deck structure of steel truss bridge
The invention discloses a bridge deck structure of a steel truss bridge. The bridge deck structure comprises a bridge deck structure body and a truss structure used for supporting the bridge deck structure body. The truss structure comprises main bridge lower chords arranged in parallel and cross beams connected between the main bridge lower chords at preset intervals. The bridge deck structure body comprises a steel bridge deck slab layer, an epoxy mortar pouring layer and floor tiles laid on the epoxy mortar pouring layer in sequence from bottom to top, and the steel bridge deck slab layer is fixed to the cross beams in a lap joint mode. Each steel bridge deck slab layer comprises a bridge deck slab body and a first stiffening plate which is perpendicular to the bridge deck slab body andwelded to the bridge deck slab body, and an expansion joint is reserved between every two adjacent steel bridge deck slab layers in lap joint with the same cross beam. The bridge deck structure of the steel truss bridge has the advantages that the service life is prolonged, and the construction difficulty is reduced and the problem of inconvenience in construction is solved.
本发明公开了一种钢桁架桥的桥面结构，包括桥面结构本体和用以支撑所述桥面结构本体的桁架结构；所述桁架结构包括平行设置的主桥下弦杆和以预设间距连接在所述主桥下弦杆之间的横梁；所述桥面结构本体包括自下至上依次设置钢制桥面板层、环氧砂浆浇筑层和铺设于所述环氧砂浆浇筑层上方的地砖，所述钢制桥面板层搭接固定于所述横梁；所述钢制桥面板层包括桥面板本体和垂直所述桥面板本体焊接第一加劲板，搭接于同一所述横梁的相邻所述钢制桥面板层之间预留有伸缩缝。本发明所提供的钢桁架桥的桥面结构寿命延长，同时降低了施工难度解决了施工不便的问题。
