Steel-concrete composite beam bridge hogging moment area bridge deck structure adapting to deformation and construction method
The invention relates to a steel-concrete composite beam bridge hogging moment area bridge deck structure adapting to deformation and a construction method, the steel-concrete composite beam bridge hogging moment area bridge deck structure adapting to deformation comprises a steel beam, a pavement surface layer, a pavement base layer and a bearing plate, the beam height of the steel beam in a hogging moment area is 10-40 cm higher than the beam height in a positive bending moment area, and the pavement base layer is located above the bearing plate; wherein an upper wing plate of the steel beam is embedded in the paving base layer or between the paving base layer and the paving surface layer, a local reinforcing net is arranged on the upper side of the upper wing plate of the steel beam or on the upper side and the lower side of the upper wing plate of the steel beam, and the local reinforcing net is combined with the paving surface layer or the paving base layer. The bridge deck structure is small in rigidity, the deformation capacity of the bridge deck structure is better under the action of loads, meanwhile, the connection between the bridge deck structure and the upper wing plate of the steel beam is weakened, the bridge deck structure bears smaller negative bending area tensile stress, and therefore the bridge deck structure can well adapt to the characteristic of large deformation of a negative bending moment area of a composite beam bridge.
本发明涉及一种适应变形的钢混组合梁桥负弯矩区桥面结构及施工方法，包括钢梁、铺装面层、铺装基层以及承载板，所述钢梁在负弯矩区的梁高比在正弯矩区的梁高向上高出10~40cm，铺装基层位于承载板上侧，钢梁的上翼板嵌埋在铺装基层内或铺装基层与铺装面层之间，所述钢梁上翼板上侧或钢梁上翼板上侧与下侧设有局部加强网，所述局部加强网与所述铺装面层或铺装基层结合在一起。本发明桥面结构刚度较小，使其在荷载作用下变形能力更佳，同时该桥面结构削弱了与钢梁上翼板的连接，使其承受更小的负弯区拉应力，这使得其能够很好地适应组合梁桥负弯矩区变形大的特性。
