Support-free construction method of steel-concrete concrete composite beam concrete cast-in-place bridge deck
The invention belongs to the technical field of bridge construction, and particularly provides a support-free construction method of a steel-concrete composite beam concrete cast-in-place bridge deck.The method comprises the following steps of installing steel main beams and steel cross beams according to drawing requirements, and machining needed profiled steel plates or steel plates according to a transverse line type of a bottom surface of a bridge deck; laying processed profiled steel plates on an upper flange plate of the steel main beams section by section in a bridge direction; installing reinforcing steel bars in the bridge deck on the laid profiled steel plates; installing side molds on the two sides of the bridge deck; and pouring concrete on the profiled steel plates and on inner sides of side molds in the step 3) and curing. Problems that in the prior art, supports and formworks need to be disassembled after bridge deck construction is completed in support construction, and a disassembling workload is large are solved; and support-free construction is adopted, dismounting operation is not needed, high-altitude operation is not needed, a safety risk is reduced, a dismounting operation platform does not need to be built, construction cost is reduced, and construction efficiency is improved.
本发明属于桥梁施工技术领域，具体提供了一种钢混组合梁混凝土现浇桥面板无支架施工方法，包括如下步骤：按图纸要求安装钢主梁及钢横梁，并按桥面板底面横向线型加工所需的压型钢板或者钢板；沿桥梁方向在钢主梁的上翼缘板上面逐段铺设加工好的压型钢板；在铺设好的压型钢板上面安装桥面板内的钢筋；在桥面板两侧安装侧模；在压型钢板的上面和步骤3)的侧模内侧浇筑混凝土并养护，解决了现有技术中支架施工在桥面板施工完成后需要对支架及模板进行拆除，拆除工作量大的问题；本发明为无支架施工，不需要进行拆除作业，不需要在高空进行，降低安全风险，且不需要搭建拆除作业平台，降低施工成本，提高施工效率。
