Bolt hinge joint structure of prefabricated bridge deck slab of full-fabricated composite beam bridge and construction method thereof
The invention relates to the field of bridge engineering, in particular to a bolt hinge joint structure of a prefabricated bridge deck slab of a full-assembly type composite beam bridge and a construction method thereof. U-shaped notches are formed in the periphery of the prefabricated bridge deck slab with holes, a channel is provided for high-strength slurry injection after the two prefabricated bridge deck slabs with holes are spliced together, annular steel bars are reserved in the U-shaped notches to improve the connection strength of splicing joints, longitudinal steel bars are inserted into the end points of the overlapping positions of the reserved annular steel bars and then bound, before high-strength slurry is poured into the hinge joints, the two ends of the U-shaped notches need to be sealed through plugs, and then the high-strength slurry is injected into the grouting holes. The structure is applied to bridge engineering construction and has the advantages of being simple in structure, convenient to assemble, high in implementation speed and the like.
本发明涉及桥梁工程领域，特指全装配式组合梁桥预制桥面板螺栓铰缝构造及其施工方法，通过在带孔预制桥面板四周设置U形槽口，为两块带孔预制桥面板拼拢后注高强浆体提供通道，为提高拼缝的连接强度，在U形槽口预留环形钢筋，并在预留环形钢筋叠合处的端点插入纵向钢筋再进行绑扎，在铰缝灌入高强浆体之前，需用堵头将U形槽口两端密封，然后在注浆孔注入高强浆体。将本申请应用于桥梁工程施工，具有结构简单、装配方便、实施速度快等优点。
