Prestressed hinge joint structure of prefabricated bridge deck slab of fully-assembled composite beam bridge and construction method of prestressed hinge joint structure
The invention relates to the field of bridge engineering, in particular to a prestressed hinge joint structure of prefabricated bridge decks of a fully-assembled composite beam bridge and a construction method thereof.The prestressed hinge joint structure comprises the prefabricated bridge decks with holes, the adjacent prefabricated bridge decks with the holes are connected through a prestressed system, vertical reserved holes are formed in the boundaries of the prefabricated bridge decks with the holes, and U-shaped notches are formed in the peripheries of the prefabricated bridge decks with the holes; an annular steel bar is preset in the U-shaped notch, plugs are arranged at the two ends of the U-shaped notch formed between every two adjacent prefabricated bridge deck slabs with holes, and high-strength slurry is injected through grouting holes formed in the prefabricated bridge deck slabs with holes to form plugging. The steel beam is arranged below the prefabricated bridge deck slab with the holes, and the steel beam is fixed to the prefabricated bridge deck slab with the holes in the mode that the bolt shear keys are matched with the vertical reserved holes. After the scheme is adopted, the device has the advantages of simple structure, convenience in assembly, high implementation speed and the like.
本发明涉及桥梁工程领域，特指全装配组合梁桥预制桥面板预应力铰缝构造及其施工方法，包括带孔预制桥面板，相邻带孔预制桥面板间通过预应力系统连接，带孔预制桥面板的边界设置有垂直预留孔，带孔预制桥面板四周设置U形槽口，U形槽口预设有环形钢筋，在相邻两块带孔预制桥面板之间形成的U形槽口两端设置有堵头，通过带孔预制桥面板上开设的注浆孔注入高强浆体形成封堵；钢梁，设置于带孔预制桥面板之下，钢梁通过螺栓剪力键配合垂直预留孔与带孔预制桥面板固定。采用上述方案后具有结构简单、装配方便、实施过程速度快等优点。
