Pier-arch steel-concrete combined section connecting structure
A pier-arch steel-concrete combined section connecting structure comprises an obliquely-arranged concrete section pier, and a steel arch rib structure is fixed to the upper side of the pier. A concrete transition section, a steel box arch transition section and a steel-concrete combined transition section formed by overlapping the concrete transition section and the steel box arch transition section are arranged between the bridge pier and the steel arch rib structure, and a pressure-bearing steel plate is arranged on the bottom surface of the steel-concrete combined transition section; the steel box arch transition section comprises transition stiffening ribs arranged between original stiffening ribs in the steel arch rib structure, and the bottoms of the original stiffening ribs and the bottoms of the transition stiffening ribs are fixed to the top face of the pressure-bearing steel plate. The steel-concrete combined transition section and the concrete transition section both comprise steel plates arranged on the peripheral side walls, the steel plates and the pressure-bearing steel plates form an upper steel jacket box and a lower steel jacket box respectively, and the upper steel jacket box and the lower steel jacket box are filled with micro-expansion concrete. The connection mode of a traditional steel-concrete structure combination section is improved, the applicability is high, connection is reliable, and the service life of the structure is prolonged.
一种墩拱钢混结合段连接结构,包括斜向设置的混凝土段桥墩，桥墩的上侧固定有钢拱肋结构；桥墩与钢拱肋结构之间设置有混凝土过渡段和钢箱拱过渡段，以及由两者重叠形成的钢混结合过渡段，钢混结合过渡段的底面设置有承压钢板；所述钢箱拱过渡段包括设置在钢拱肋结构中原有加劲肋之间的过渡加劲肋，原有加劲肋与过渡加劲肋的底部固定在承压钢板的顶面；钢混结合过渡段和混凝土过渡段均包括设置在四周侧壁上的钢板，所述钢板分别与承压钢板形成上钢套箱和下钢套箱，上钢套箱和下钢套箱内填微膨胀砼。本发明改善了传统钢混结构结合段的连接方式，适用性较强，连接可靠，提高结构使用寿命。
