Fully-assembled prestressed connection type steel-concrete composite beam bridge structure and construction method
The invention relates to the field of bridge engineering, in particular to a fully-assembled prestressed connection type steel-concrete composite beam bridge structure and a construction method. The fully-assembled prestressed connection type steel-concrete composite beam bridge structure comprises a prefabricated bridge deck slab with holes, and vertical reserved holes and horizontal reserved holes are formed in the boundary of the prefabricated bridge deck slab with the holes; the horizontally-laid prefabricated bridge deck slabs with the holes are connected through cooperation of horizontal reserved holes and a prestress system, and the junctions between the prefabricated bridge deck slabs with the holes are filled with epoxy resin layers. The structure also includes steel beams with holes, which are arranged below the adjacent prefabricated bridge deck slabs with the holes and located above the bridge piers at the same time, and upper wing plates of the steel beams with the holes are fixed to the prefabricated bridge deck slabs with the holes in the mode that bolt shear keys are matched with the vertical reserved holes; the prestress system is installed after the epoxy resin layer is filled. The construction technology is simple, the influence on surrounding traffic and environment is small during structure construction, the construction period is short, and the good social value is achieved.
本发明涉及桥梁工程领域，特指一种全装配预应力连接式钢混组合梁桥构造及施工方法，包括带孔预制桥面板，带孔预制桥面板的边界设置有垂直预留孔和水平预留孔，水平铺设的带孔预制桥面板之间通过水平预留孔配合预应力系统连接，且带孔预制桥面板之间的交界处通过环氧树脂层填充；带孔钢梁，设置于相邻带孔预制桥面板之下，同时位于桥墩之上，带孔钢梁的上翼板通过螺栓剪力键配合垂直预留孔与带孔预制桥面板固定；预应力系统在环氧树脂层填充之后安装。本发明施工工艺简单，结构施工时对周边交通及环境影响小，施工周期短，有比较好的社会价值。
