Semi-penetration type rectangular concrete filled steel tube combined trussed beam bridge and construction method
The invention discloses a semi-penetration type rectangular concrete filled steel tube combined trussed beam bridge and a construction method. The bridge comprises bridge lower supporting structures and a fabricated rectangular concrete filled steel tube main truss arranged on the bridge lower supporting structures. A prefabricated concrete bridge panel is arranged on the fabricated rectangular concrete filled steel tube main truss. The fabricated rectangular concrete filled steel tube main truss comprises a fabricated steel truss main beam. The fabricated steel truss main beam comprises two trusses arranged side by side in the longitudinal direction. Each truss comprises an upper chord member, a lower chord member and web members between the upper chord member and the lower chord member.Multiple cross beams are arranged between the trusses. According to the semi-penetration type rectangular concrete filled steel tube combined trussed beam bridge, design is reasonable, the use effectis good, the mechanical properties of steel and concrete can be fully played, fabricated construction can be achieved for the steel main beam and the prefabricated concrete bridge panel, the construction speed is high, the construction cost is low, and standard and batched production of the steel main beam and the bridge panel can be achieved.
本发明公开了一种半穿式矩形钢管混凝土组合桁梁桥及施工方法，包括桥梁下部支撑结构、设置于桥梁下部支撑结构上的装配式矩形钢管混凝土主桁，装配式矩形钢管混凝土主桁上设置预制混凝土桥面板，装配式矩形钢管混凝土主桁包括装配式钢桁主梁，装配式钢桁主梁包括两个纵向并排布设的桁架，每个桁架包括上弦杆、下弦杆以及上弦杆和下弦杆之间的腹杆，桁架之间设置有多道横梁。本发明设计合理、使用效果良好，能够充分发挥钢材和混凝土各自的力学特性，钢主梁和预制混凝土桥面板都能实现装配化施工，施工速度快且造价低，可以实现钢桁主梁和桥面板的标准化、批量化生产。
