Narrow steel box-reinforced concrete bridge deck slab combined bridge construction system and construction method
The invention discloses a narrow steel box-reinforced concrete bridge deck slab combined bridge construction system and method. The system comprises narrow steel box beams, a reinforced concrete combined bridge deck slab, cross beams and connecting piece welding units. By conducting simulation optimization design on the internal structure of the narrow steel box girder, vertical stiffening ribs on the inner surfaces of a box girder bottom plate and a box girder top plate can be omitted, the spanning capacity is increased by adopting the steel-concrete combined bridge deck with good durability, and the longitudinal beam structure and the cross beam structure of a bridge deck system are simplified. In addition, due to the fact that a beam lattice structure of a bridge deck system and other additional rod materials are not arranged, the maintenance workload can be reduced, and the structure type is good in economical efficiency. Meanwhile, the bottom plate of the steel-concrete combined bridge deck slab structure is of a steel structure to replace a traditional concrete bottom layer structure, supporting of a bottom die is omitted in the manufacturing process while the bearing capacity of the bridge deck slab is improved, and after supporting of the side die is completed, machining of the steel-concrete combined bridge deck slab can be completed by directly pouring concrete on the upper surface of the bottom steel plate.
本发明公开了一种窄幅钢箱‑钢混桥面板组合桥梁施工系统及施工方法，系统包括窄幅钢箱梁、钢混组合桥面板、横梁、连接件焊接单元；通过对窄幅钢箱梁内部结构进行仿真优化设计，可省去箱梁底板与箱梁顶板内表面的竖向加劲肋，加上采用了耐久性良好的钢混组合桥面板增大了跨越能力，使得桥面系纵、横梁构造简化。另外，由于没有桥面系的梁格结构和其它附加杆材，可减少维护工作量，是一种经济性较好的结构型式；与此同时，钢混组合桥面板结构底板采用钢结构，以替代传统混凝土底层结构，该方案在提高桥面板承载能力的同时，在制造过程中省去了底模的支设，侧模支设完成后，直接在底钢板上表面浇筑混凝土即可完成钢混组合桥面板的加工。
