Mechanical hinge butt strap connecting structure for bridge widening and construction method of mechanical hinge butt strap connecting structure
The invention relates to a mechanical hinge butt strap connecting structure for a bridge widening structure and construction steps. A mechanical hinge structure is arranged at the end of an old bridge cantilever, one end of a stiffening steel butt strap is connected with the mechanical hinge structure, and the other end of the stiffening steel butt strap is placed on a new bridge cantilever. A rubber cushion block is arranged between the stiffening steel butt strap and the new bridge cantilever, steel base plates are arranged above the two ends of the stiffening steel butt strap, elastic materials are laid on the steel base plates and the steel butt strap, and the elastic materials are fixed to a bridge body through anchoring parts. The mechanical hinge butt strap connecting structure is high in applicability, capable of thoroughly solving the problem that the displacement difference is large when the new bridge and the old bridge are spliced, particularly high in adaptability to vertical displacement, the new bridge and the old bridge are independently stressed, the load borne by the old bridge is not changed, the old bridge does not need to be reinforced, and meanwhile the structure can effectively resist water and cracks, and is safe and durable.
本发明涉及一种用于桥梁拼宽结构的机械铰接搭板连接构造和施工步骤，老桥挑臂端部设置机械铰接构造，加劲钢搭板的一端与所述机械铰接构造连接，加劲钢搭板的另一端搁置在新桥挑臂上，所述加劲钢搭板与新桥挑臂之间设置橡胶垫块，加劲钢搭板两端上方设置钢垫板，钢垫板和钢搭板上摊铺弹性材料，所述弹性材料用锚固件与桥梁梁体固定；本发明适用性强，可彻底解决新老桥拼接时位移差大的问题，尤其是对竖向位移适应性强，且新老桥单独受力，老桥所受荷载不变，无需对老桥加固加强，同时构造上能有效防水防裂，安全耐久。
