Plate-truss combined girder suitable for large-span cable-stayed bridge in mountainous area
The invention relates to a plate-truss combined girder suitable for a large-span cable-stayed bridge in a mountainous area, which is used for effectively improving the construction efficiency, solving the technical problem that the bridge deck pavement of a steel bridge deck system is easy to crack and solving the fatigue problem of a traditional steel bridge deck slab. The girder is composed of a steel truss bridge deck structure, the bridge deck structure is a steel-concrete combined bridge deck composed of steel bottom plates and cast-in-place steel fiber concrete, the steel bottom plates are arranged between the adjacent cross beams, the adjacent longitudinal beams and the main truss upper chords and the adjacent longitudinal beams, and supports are arranged at the welding joints of the steel bottom plates, the main truss upper chords, the longitudinal beams and the cross beams. The cast-in-place steel fiber concrete is connected with the steel bottom plate, the main truss upper chord, the longitudinal beams and the cross beams into a whole through shear keys.
一种适合山区大跨斜拉桥的板桁组合主梁，以有效提高施工效率，克服钢桥面系桥面铺装容易开裂的技术难题，而且避免传统钢桥面板的疲劳问题。主梁由钢桁梁桥面结构构成，所述桥面结构为由钢底板、现浇钢纤维混凝土构成的钢‑混凝土组合桥面板，钢底板设置在相邻横梁、相邻纵梁、主桁架上弦杆与相邻纵梁之间，钢底板与主桁架上弦杆、纵梁和横梁焊接连接处设置承托，现浇钢纤维混凝土通过剪力键与钢底板、主桁架上弦杆、纵梁和横梁连接为一体。
