Articulated bridge and construction method
The invention discloses a hinged bridge and a construction method, and relates to the technical field of bridge construction.The construction method comprises the following steps that pre-embedded steel bars are arranged at the top of a cover beam; the lower ends of the embedded steel bars are anchored in the cover beam, and the upper ends are exposed out of the top of the cover beam; the upper end of the embedded steel bar is sleeved with a connecting sleeve; the two prefabricated box girders are erected on the two opposite sides of the top of the cover beam correspondingly, and a reserved pouring area is formed between the two opposite ends of the two prefabricated box girders; the connecting sleeve is located in the reserved pouring area; concrete is poured into the reserved pouring area to form a post-pouring end cross beam, and the post-pouring end cross beam is fixedly connected with the connecting sleeve; and the post-cast end cross beam and the two prefabricated box girders form a bridge deck structure. According to the technical scheme, a hinge structure is formed between the bridge deck structure and the cover beam, construction is convenient, the manufacturing cost is low, maintenance is convenient, bending moment is released while horizontal displacement of the bridge deck structure is effectively limited, and the structural stability, safety and durability of a bridge are improved.
本发明公开了一种铰接式桥梁和施工方法，涉及桥梁施工技术领域，其中，该施工方法包括以下步骤：在盖梁的顶部设置预埋钢筋；预埋钢筋的下端锚固于盖梁内部、上端外露于盖梁的顶部；在预埋钢筋的上端套设连接套筒；将两个预制箱梁分别架设于盖梁的顶部的相对两侧，两个预制箱梁相对的两端部之间形成预留浇筑区域；连接套筒位于预留浇筑区域中；往预留浇筑区域中浇筑混凝土，以形成后浇端横梁，后浇端横梁与连接套筒固接；后浇端横梁与两个预制箱梁构成桥面结构。本发明提供的技术方案使桥面结构与盖梁之间形成铰接结构，施工方便、造价经济且便于维护，在有效限制桥面结构水平位移的同时释放了弯矩，提升了桥梁的结构稳定性、安全性和耐久性。
