Double-width large cantilever box girder splicing structure and method
The invention discloses a double-amplitude large cantilever box girder splicing structure and method. The double-width large-cantilever box girder splicing structure comprises a connecting body poured by concrete, a transverse rib poured by concrete, a hoop and a mortise and tenon joint, the hoop and the mortise and tenon joint are used for reinforcing connection of the transverse rib and a box girder, flange plates of two bridges are connected through the connecting body, the length of the connecting body is consistent with that of the box girder, and the connecting body is connected with the transverse rib through the mortise and tenon joint. The two ends of the transverse ribs are connected with the corresponding box girders respectively, a plurality of cross beams are arranged between the two box girders at intervals, steel bars are arranged in the transverse ribs and extend into the box girders, the hoops are connected with the transverse ribs and the box girders at the same time, and the mortise and tenon joints are connected with the transverse ribs and the box girders at the same time. According to the double-width large cantilever box girder splicing structure and method, the overall shear bearing capacity after splicing and the overall rigidity of a bridge floor can be improved.
本发明公开了一种双幅大悬臂箱梁拼接结构及方法。所述双幅大悬臂箱梁拼接结构包括采用混凝土浇注的连接体、采用混凝土浇注的横肋、用于加固横肋与箱梁连接的套箍和榫卯，所述连接体将两桥梁的翼缘板连接，所述连接体的长度与箱梁的长度一致，所述横肋的两端分别与对应的箱梁连接，两箱梁间间隔设置有多个横梁，所述横肋内设有钢筋，所述钢筋伸入箱梁内，所述套箍同时与横肋和箱梁连接，所述榫卯同时与横肋和箱梁连接。所述双幅大悬臂箱梁拼接结构及方法能够提高拼接后的整体的抗剪承载力和桥面的整体刚度。
