Continuous rigid frame-steel truss combined bridge for highway and railway layering and manufacturing method of continuous rigid frame-steel truss combined bridge
The invention discloses a continuous rigid frame-steel truss combined bridge for highway-railway layering, which comprises an upper-layer bridge deck structure, a lower-layer rigid frame structure andsteel truss web members, and is characterized in that the upper-layer bridge deck structure is a steel-concrete combined beam or an orthotropic bridge deck slab; the lower-layer rigid frame is mainlycomposed of a box girder and rigid frame piers, and the box girder is fixedly connected to the rigid frame piers; the lower ends of the steel truss web members are inserted into the box girder to achieve fixed connection of the steel truss web members and the box girder, shear keys are arranged between the steel truss web members and the box girder, and the upper ends of the steel truss web members are fixedly connected with the upper-layer bridge deck structure in a gusset plate welding or bolting mode. The lower-layer rigid frame structure adopts a continuous rigid frame, the structure is large in overall and local rigidity, good in stability, small in temperature linkage, convenient to construct, low in manufacturing cost and more beneficial to improving the traveling comfort of a high-speed railway, the upper-layer bridge deck structure can adopt a steel-concrete composite beam or orthotropic bridge deck slab structure flexibly according to construction conditions, the construction method is flexible, and later maintenance is convenient.
本发明公开了一种用于公铁分层的连续刚构‑钢桁组合桥，包括上层桥面结构、下层刚构结构和钢桁腹杆，所述上层桥面结构为钢混组合梁或正交异性桥面板；所述下层刚构主要由箱梁和刚构墩，所述箱梁固接在所述刚构墩上；所述钢桁腹杆的下端插入所述箱梁内以实现两者的固接，并且两者之间设置有抗剪键，所述钢桁腹杆的上端与所述上层桥面结构通过节点板焊接、或栓接的方式实现固接。本发明的下层刚构结构采用连续刚构，结构整体及局部刚度大，稳定性好、温度联小、施工方便，造价低廉，更利于提高高速铁路的行车舒适性，上层桥面结构采用可根据施工条件灵活采用钢‑混组合梁或正交异性桥面板结构，施工方法灵活，后期维养方便。
