Steel-concrete composite bridge panel wet joint structure and construction method
The invention particularly relates to a steel-concrete composite bridge panel wet joint structure and a construction method, so as to solve the field construction problem caused by inaccurate positioning of reserved steel bars of a prefabricated bridge panel in the prior art. The wet joint structure is composed of bridge deck slab reinforcing steel bars, U-shaped connecting bars and reinforcing steel bar connectors. Compared with a traditional prefabricated bridge panel, the length of the end steel bars is remarkably reduced, the U-shaped connecting bars are connected through the steel bar connectors to form wet joint steel bars after the bridge panel is placed, and the wet joint steel bars and the adjacent prefabricated plate wet joint steel bars are staggered to form a framework. In addition, according to the prefabricated bridge panel, when the reinforcing steel bars are pre-buried, the reinforcing steel bars are tensioned to form pre-stressing force on the concrete. According to the wet joint structure, the construction difficulty can be effectively reduced, the construction strength is met while the construction steps are reduced, and good popularization significance is achieved.
本发明具体涉及一种钢混组合桥梁面板湿接缝构造及施工方法。针对现有技术中预制桥梁面板预留钢筋位置定位不准导致的现场施工问题，本发明提供了一种钢混组合桥梁面板湿接缝构造及施工方法。本发明提供的湿接缝构造由桥面板钢筋、U形连接筋、钢筋连接器三部分组成，相比传统的预制桥梁面板显著缩短了端部钢筋的长度，将桥梁面板放置好之后通过钢筋连接器对U形连接筋进行连接形成湿接缝钢筋，并与相邻预制板湿接缝钢筋交错形成骨架。另外，本发明提供的预制桥梁面板在预埋钢筋时通过张紧钢筋对混凝土形成预加力。该湿接缝构造能够有效降低施工难度，节约施工步骤的同时满足施工强度，具有良好的推广意义。
