Non-geocell steel-concrete combined section structure based on UHPC (Ultra High Performance Concrete) and construction method thereof
The invention provides a cell-free steel-concrete combined section structure based on UHPC. The cell-free steel-concrete combined section structure comprises a concrete box girder transition section, a steel-concrete combined section and a steel box girder transition section which are arranged in sequence. The steel-concrete combined section comprises a steel box structure and a UHPC structure poured in the steel box structure, the steel box structure comprises a mixing section top plate, a mixing section bottom plate, a mixing section web, a mixing section flange plate and a steel bearing plate, and the steel bearing plate is arranged between the steel-concrete combined section and the steel box girder transition section and fixedly connected with the steel box girder transition section; the mixing section web is a double-arm plate, and a plurality of rows of first shear nail connecting pieces are arranged on the side walls of the mixing section top plate, the mixing section bottom plate, the mixing section web and the steel bearing plate. The non-geocell steel-concrete combined section structure based on the UHPC has the advantages of being simple in structure, clear in force transmission, good in connecting effect, easy and convenient to construct and the like. The invention further provides a construction method of the cell-free steel-concrete combined section structure based on the UHPC.
本发明提供一种基于UHPC的无格室钢混结合段结构，包括依次设置的混凝土箱梁过渡段、钢混结合段和钢箱梁过渡段；所述钢混结合段包括钢箱结构、以及浇筑于钢箱结构内的UHPC结构，所述钢箱结构包括由混合段顶板、混合段底板、混合段腹板、混合段翼缘板、以及设于所述钢混结合段与所述钢箱梁过渡段之间且与钢箱梁过渡段固定连接的钢承压板，所述混合段腹板为双臂板，且所述混合段顶板、混合段底板、混合段腹板、及钢承压板侧壁均设有若干排第一剪力钉连接件。本发明提供的基于UHPC的无格室钢混结合段结构，具有结构简单、传力明确、连接效果好、施工简便等特点。本发明还提供一种基于UHPC的无格室钢混结合段结构的施工方法。
