Fabricated steel-concrete composite bridge and construction method thereof
The invention discloses a fabricated steel-concrete composite bridge which comprises a steel main body beam and a concrete cantilever slab, wherein the steel main body beam comprises a steel main body part, a welding stud part extending out of the upper part of the steel main body part, and a bolt part arranged above the steel main body part; the concrete cantilever slab comprises a cantilever slab main body and a steel bar part extending into the welding stud part from one side of the cantilever slab main body; the steel bar part is inserted into the welding stud part, an internal reserved clamping groove formed by sinking is formed in the lower portion of the cantilever slab main body, and the bolt part is inserted into the internal reserved clamping groove. The invention further discloses a construction method of the fabricated steel-concrete composite bridge. The fabricated steel-concrete composite bridge and the construction method thereof aim at solving the technical problems that in the prior art, a scheme for achieving a small concrete cantilever slab through on-site formwork erecting and pouring is poor in stress performance, complex in working procedure and long in construction time.
本发明公开了一种装配式钢混组合桥梁，包括钢主体梁和混凝土悬臂板，所述钢主体梁包括：钢主体部、由所述钢主体部上部伸出的焊钉部、设于钢主体部上方的插销部，所述混凝土悬臂板包括：悬臂板主体、由悬臂板主体的一侧伸入所述焊钉部的钢筋部，所述钢筋部插入所述焊钉部内，所述悬臂板主体的下方设有凹陷而成的内部预留卡槽，所述插销部插入所述内部预留卡槽内。本发明还公开了如上所述的装配式钢混组合桥梁的施工方法。该装配式钢混组合桥梁及其施工方法旨在解决现有技术中的采用现场立模浇筑实现小板混凝土悬臂板的方案存在受力性能差、工序复杂及施工时间长的技术问题。
