Steel-concrete combined section for hybrid beam cable-stayed bridge and hybrid beam cable-stayed bridge
The invention provides a steel-concrete combined section for a hybrid beam cable-stayed bridge and the hybrid beam cable-stayed bridge. The steel-concrete combined section comprises a bottom plate extending section, a web plate extending section, a top plate extending section, a transition section steel stiffening rib and a bearing plate. The transition section steel stiffening rib is arranged onthe bottom plate extending section, a front end of the transition section steel stiffening rib is connected with a bottom plate longitudinal stiffening rib of a main span composite beam, and the rearend is connected with the bearing plate; a perforated steel web is arranged at the front end of the bearing plate; a PBL steel bar connecting piece is arranged in a connecting hole of the perforated steel web in a penetrating manner; concrete is poured on one side, close to a side span concrete beam, of the bearing plate; concrete is poured at the rear end of the bearing plate, the rear end is connected with the side span concrete beam, and the top of the front end is connected with a steel girder top plate; and a plurality of shear connectors are arranged on the steel surfaces, making contactwith concrete, of the bearing plate, the bottom plate extending section and the web plate extending section. By applying the combined section and the bridge, defects of a complex structure and difficulty in construction of the combined section of the hybrid beam cable-stayed bridge in the prior art can be overcome.
本发明提供了一种用于混合梁斜拉桥的钢‑混凝土结合段以及混合梁斜拉桥，该钢‑混凝土结合段包括：底板延伸段、腹板延伸段、顶板延伸段、过渡段钢加劲肋、承压板；过渡段钢加劲肋设置在底板延伸段上，其前端与主跨组合梁的底板纵向加劲肋连接，后端与承压板连接；承压板的前端设置有开孔钢腹板；开孔钢腹板的连接孔内穿设有PBL钢筋连接件；承压板的邻近边跨混凝土梁的一侧浇筑有混凝土；混凝土浇筑于承压板的后端，其后端与边跨混凝土梁连接，其前端的顶部与钢主梁顶板连接；承压板、底板延伸段以及腹板延伸段在与混凝土接触的钢表面上设置有多个剪力连接件。应用本发明可改善现有技术中的混合梁斜拉桥结合段构造复杂、施工困难的缺点。
