Fabricated corrugated steel web composite beam bridge deck slab structure and construction method
The invention discloses a bridge deck slab structure of a fabricated corrugated steel web composite beam bridge and a construction method. The bridge deck slab structure comprises a box beam body. The open steel plate is welded to a flange plate of the box girder body, and a plurality of U-shaped bayonets are formed in the open steel plate at equal intervals; the bridge deck slab assembly comprises a first bridge deck slab and two second bridge deck slabs, cast-in-place grooves are reserved between the first bridge deck slab and the second bridge deck slabs, the cast-in-place grooves are formed in the tops of the flange plates, and transverse steel bars penetrate through the U-shaped bayonets and connect the first bridge deck slab and the second bridge deck slabs; and the concrete layer is poured in the cast-in-place groove for solidification. The open steel plates welded on the flange plates are used for bearing shear force, and compared with a traditional shear key, the shear key has higher shear rigidity and ductility; and when the bridge deck is installed by hoisting the bridge deck, the transverse reinforcing steel bars correspond to the U-shaped bayonets in the open steel plates, compared with traditional hole-shaft connection, assembly is simpler, alignment is easy, and the installation efficiency is improved.
本发明公开了一种装配式波形钢腹板组合梁桥桥面板结构及施工方法，桥面板结构包括箱梁本体；开口钢板，其焊接在箱梁本体的翼缘板上，开口钢板等距设置有多个U形卡口；桥面板组件，其包括第一桥面板和两个第二桥面板，第一桥面板与第二桥面板之间留有现浇槽，现浇槽设置在翼缘板的顶部，横向钢筋穿过U形卡口并将第一桥面板和第二桥面板连接；混凝土层，其浇注在现浇槽中以进行固结。本发明通过焊接在翼缘板上的开口钢板承受剪力，相较于传统的剪力键具有更高抗剪刚度和延性；且通过吊装桥面板进行安装时，横向钢筋与开口钢板上的U形卡口对应即可，相较于传统的孔轴连接其装配更为简单且容易对准，提升安装效率。
