Steel-concrete combined section structure of large-span hybrid combined beam of high-speed railway
Disclosed is a steel-concrete combined section structure of a large-span hybrid combined beam of a high-speed railway. The steel-concrete combined section structure comprises an open steel box girder, a concrete bridge deck and a concrete box girder, a steel beam tuyere plate is formed at the free end of a steel beam bottom plate at the bottom of the open steel box girder, and the steel beam bottom plate and the steel beam tuyere plate wrap the concrete box girder. A steel beam middle web plate and a steel beam side web plate of the open steel box beam are embedded into the concrete box beam, and combination of the open steel box beam and the concrete box beam is achieved. Concrete is poured on a top plate, a bottom plate and a web plate on the side span concrete beam side of the front bearing plate, concrete is poured on the top plate and the bottom plate between the front bearing plate and the rear bearing plate, concrete is poured only on the top plate on the middle span combination beam side of the rear bearing plate, and heightening transition stiffening ribs are arranged on the combination beam. Through graded transition and thickness change of concrete of the top plate, the bottom plate and the web, smooth rigidity transition between the concrete beam and the composite beam is achieved, and the composite beam is particularly suitable for a high-speed railway large-span composite composite beam with the high requirement for riding comfort.
本发明公开了一种高速铁路大跨度混合结合梁的钢混结合段结构，包括开口钢箱梁、混凝土桥面板和混凝土箱梁，所述开口钢箱梁底部的钢梁底板自由端形成钢梁风嘴板，所述钢梁底板、钢梁风嘴板外包混凝土箱梁，所述开口钢箱梁的钢梁中腹板及钢梁边腹板埋入混凝土箱梁，实现开口钢箱梁、混凝土箱梁的结合。本发明中前承压板边跨混凝土梁侧顶板、底板、腹板均浇筑混凝土，前后承压板之间顶板、底板浇筑混凝土，后承压板中跨结合梁侧仅顶板浇筑混凝土，并在结合梁设置变高过渡加劲肋。通过顶板、底板、腹板混凝土分级过渡及厚度变化，实现混凝土梁与结合梁刚度过渡平顺，特别适合对行车平顺性要求高的高速铁路大跨度混合结合梁。
