Prefabricated assembly construction method and supporting connection structure of steel-concrete combined bridge deck slab
The invention relates to the technical field of bridge construction, in particular to a prefabricated assembly construction method of a steel-concrete combined bridge deck slab and a supporting connection structure. The steel-concrete combined bridge deck slab is prefabricated in a blocking mode, and the edge of a steel bottom plate of a single prefabricated plate extends out of a concrete slab to be bent; the bent edge directly abuts against the steel main beam during on-site rapid assembly construction, so that the bent edge of the steel bottom plate is connected with the steel main beam through the fillet weld, welding construction is convenient, and the quality of the weld is reliable. After concrete is poured at the wet joints, the thickness of the concrete at the wet joints is larger than that of the prefabricated plates, the bearing capacity and rigidity of the bridge deck in the hogging moment area are improved, and the structural stress performance is good.
本发明涉及桥梁施工技术领域，具体涉及一种钢混组合桥面板的预制拼装施工方法及支承连接构造，本发明通过分块预制钢混组合桥面板并将单块预制板块的钢底板边缘伸出混凝土板折弯设置，以在现场快速拼装施工时将折弯边缘直接抵接在钢主梁上，使折弯的钢底板边缘与钢主梁通过角焊缝连接，焊接施工方便、焊缝质量可靠；在湿接缝处浇筑混凝土后，湿接缝位置的混凝土厚度大于预制板块自身的厚度，提高了负弯矩区域桥面板承载能力及刚度，结构受力性能好。
