Wet joint structure of steel-concrete composite structure bridge and construction method of wet joint structure
The invention provides a steel-concrete composite structure bridge wet joint structure and a construction method thereof.The steel-concrete composite structure bridge wet joint structure comprises a steel beam and prefabricated bridge deck slabs, the prefabricated bridge deck slabs are divided into the left prefabricated bridge deck slab and the right prefabricated bridge deck slab, a wet joint is formed between the left prefabricated bridge deck slab and the right prefabricated bridge deck slab, and concrete is poured into the wet joint; the left side prefabricated bridge deck slab and the right side prefabricated bridge deck slab are each provided with an upper layer of embedded steel bar and a lower layer of embedded steel bar extending into wet joints, and the end of the lower layer of embedded steel bar of the left side prefabricated bridge deck slab is bent downwards and then penetrates through the upper flange plate on the right side of a web of the steel beam to be fixed; the ends of the lower-layer embedded steel bars of the right-side prefabricated bridge deck slab are bent downwards and then penetrate through the upper flange plate on the left side of the steel beam web to be fixed, and the upper-layer embedded steel bars of the left-side prefabricated bridge deck slab and the upper-layer embedded steel bars of the right-side prefabricated bridge deck slab are connected in a welded mode. The industrialization degree is high, the workload of steel bar welding at the wet joint site is remarkably reduced, and the overall construction efficiency of the bridge is improved.
本发明提供一种钢混组合结构桥梁的湿接缝构造及其施工方法，包括钢梁、预制桥面板，所述预制桥面板分为左侧预制桥面板、右侧预制桥面板，所述左侧预制桥面板和右侧预制桥面板之间为湿接缝，所述湿接缝内浇筑混凝土，所述钢梁上翼缘板上焊有栓钉，所述左侧预制桥面板和右侧预制桥面板均设有上下两层预埋钢筋伸入湿接缝，所述左侧预制桥面板的下层预埋钢筋端部向下弯折后穿过钢梁腹板右侧的上翼缘板进行固定，所述右侧预制桥面板的下层预埋钢筋端部向下弯折后穿过钢梁腹板左侧的上翼缘板进行固定，所述左侧预制桥面板和右侧预制桥面板的上层预埋钢筋之间焊接连接，本发明施工速度快，还具有抗拔连接件和抗剪连接件的作用，工业化程度高，显著降低了将湿接缝处现场的钢筋焊接工作量，提升了桥梁的整体施工效率。
