Wet-joint-free steel-concrete combined continuous beam and construction method thereof
The invention discloses a wet-joint-free steel-concrete combined continuous beam and a construction method thereof.The steel-concrete combined continuous beam comprises a plurality of steel-concrete combined beams, the steel-concrete combined beams are connected in a matched mode to form the steel-concrete combined continuous beam, each steel-concrete combined beam comprises an I-shaped beam, the I-shaped beam comprises a web, a top plate and a bottom plate, and the top plate and the bottom plate are connected through the web; the bottom-layer bridge deck slab is connected with the top plate in a matched mode, and the bottom-layer bridge deck slab is formed by pouring reinforced concrete; the top-layer bridge deck slab is connected with the bottom-layer bridge deck slab in a matched mode, and the top-layer bridge deck slab is formed by pouring reinforced concrete; and the shear nails are arranged on the top plate, penetrate through the bottom-layer bridge deck slab and extend into the top-layer bridge deck slab. The method has the advantages that a wet joint mode is not adopted for a bridge structure, on-site hanging bracket-free construction of the top-layer bridge deck slab is achieved, the construction period and materials are saved, falling objects generated during high-altitude operation are reduced, and the safety of construction operation is greatly guaranteed.
本发明公开了一种无湿接缝的钢混组合连续梁及其施工方法，钢混组合连续梁包括多个钢混组合梁，多个钢混组合梁配合连接形成钢混组合连续梁，钢混组合梁包括：工字梁，工字梁包括腹板、顶板和底板，腹板将顶板和底板连接；底层桥面板，底层桥面板与顶板配合连接，底层桥面板为钢筋混凝土浇筑而成；顶层桥面板，顶层桥面板与底层桥面板配合连接，顶层桥面板为钢筋混凝土浇筑而成；多个剪力钉，剪力钉设于顶板上，剪力钉穿过底层桥面板，伸入顶层桥面板。本发明的优点是：桥梁结构未采用湿接缝的方式，实现顶层桥面板现场无吊架施工，节省了施工周期与材料，减少了高空作业的坠物，极大地保证施工作业的安全。
