Fabricated steel-concrete composite beam and construction technology
The invention discloses a fabricated steel-concrete composite beam and a construction technology, and belongs to the technical field of civil engineering. The fabricated steel-concrete composite beam comprises a plurality of bridge units which are assembled to form a bridge, each bridge unit comprises a steel beam and a concrete panel, the steel beam comprises a first steel plate, a second steel plate and a transverse steel beam, the first steel plate and the second steel plate are vertically arranged in parallel, and the first steel plate and the second steel plate are fixedly connected through the transverse steel beam; the concrete panel is fixed to the tops of the first steel plate and the second steel plate, and comb tooth structures are arranged on the tops of the first steel plate and the second steel plate and located in the concrete panel. The steel beam part and the concrete bridge deck part of the fabricated steel-concrete composite beam MVFT beam are all prefabricated in a factory, secondary concrete slab pouring is not needed, and the construction period is greatly shortened. The manufacturing process of the MVFT composite beam bridge is simple, the self weight is light, and the fatigue performance of the MVFT composite beam bridge is better through the comb tooth structure and the variable cross-section design.
本发明公开了一种装配式钢‑混凝土组合梁及施工工艺，属于土木工程技术领域。该装配式钢‑混凝土组合梁包括多个装配构成桥梁的桥梁单元，各桥梁单元均包括钢梁和混凝土面板，钢梁包括第一钢板、第二钢板和横钢梁，所述第一钢板和第二钢板竖向平行设置，且第一钢板和第二钢板之间通过横钢梁固定连接；混凝土面板固定于第一钢板和第二钢板的顶部，第一钢板和第二钢板顶部设有梳齿结构且位于混凝土面板内部。本发明的装配式钢‑混凝土组合梁MVFT梁的钢梁部分和混凝土桥面板部分全部在工厂预制，不用二次浇筑混凝土板，极大缩短施工周期。MVFT组合梁桥的制作过程较为简单，且自重较轻，且采用梳齿结构以及变截面设计使得MVFT组合梁桥疲劳性能更优。
