Combined type formwork-erecting-free new and old widened bridge wet joint connecting structure
The invention discloses a combined type formwork-erecting-free new and old widened bridge wet joint connecting structure. The structure comprises an old bridge inner side edge beam, a new bridge inner side edge beam, a wet joint and a steel plate, and the wet joint is located between the old bridge inner side edge beam and the new bridge inner side edge beam. The cast-in-place concrete in the wet joint, the old bridge inner side edge beam and the new bridge inner side edge beam are poured together to form a connecting structure resistant to vertical shearing and transverse bending. Longitudinal steel bars, transverse steel bars and stirrups are further arranged in the wet joint, a steel plate is arranged at the bottom of the wet joint and connected with the new bridge edge beam and the old bridge edge beam through bolts, and the steel plate at the bottom can replace a formwork, can bear shearing force and bending moment of the wet joint area at the same time and bears loads together with concrete. A wet joint concrete pouring formwork can be omitted, and the construction speed is increased; the transverse connection between the new and old widened bridges can be enhanced, and the overall performance of the new and old widened bridges is improved.
本发明公开了一种组合式免支模新旧拼宽桥梁湿接缝连接结构，包括旧桥内侧边梁、新桥内侧边梁、湿接缝和钢板，所述湿接缝位于旧桥内侧边梁与新桥内侧边梁之间，湿接缝内的现浇混凝土与旧桥内侧边梁、新桥内侧边梁浇筑在一起形成抗竖向剪切和横向弯曲的连接结构。所述湿接缝内还包括纵向钢筋、横向钢筋、箍筋，湿接缝底部设有钢板，钢板通过螺栓与新桥边梁和旧桥边梁相连，底部钢板可代替模板，同时可承受湿接缝区域的剪力和弯矩，与混凝土共同承担荷载。本发明可免除湿接缝混凝土浇筑模板，提高施工速度；可加强新旧拼宽桥梁横向之间的联系，提高新旧拼宽桥梁的整体性能。
