Construction method for reversely hanging cast-in-place bridge deck slab through sluice pier top supporting steel beams
The invention discloses a construction method for reversely hanging a cast-in-place bridge deck by supporting steel beams at the tops of sluice piers, which comprises the following steps of: firstly, preparing for construction, mounting steel supports at the tops of the sluice piers, erecting upper main longitudinal beams on the steel supports mounted at the tops of the adjacent sluice piers, erecting lower main longitudinal beams below the upper main longitudinal beams, and erecting lower main longitudinal beams below the lower main longitudinal beams; the upper main longitudinal beam and the lower main longitudinal beam are kept at the fixed hanging positions through deformed steel bars, a distribution beam is laid on the lower main longitudinal beam, a supporting layer is laid on the distribution beam, then a bridge floor mold is laid on the supporting layer, concrete is poured into the mold, and after the concrete is solidified and formed, the reverse hanging structure is dismantled; the reverse hanging supporting structure has the advantages that the impact resistance is high, the erecting process is convenient, the dependence on the sluice operation condition is weak, the influence on the sluice pier structure is small, the reliability of the formwork structure is high, the reverse hanging supporting structure is simple in composition, and a mechanical system is reliable; and the economic benefit is high.
本发明公开了一种过水闸墩顶支撑钢梁反吊现浇桥面板的施工方法，包括以下步骤：先进行施工准备，在水闸墩顶部安装钢支座，将上主纵梁架设在相邻水闸墩顶部安装的钢支座上，再在上主纵梁的下方架设下主纵梁，通过螺纹钢将上主纵梁和下主纵梁保持固定吊挂的位置，在下主纵梁上铺设分配梁，在分配梁上铺设支撑层，再在支撑层上铺设桥面模具，在模具内浇筑混凝土，待混凝土凝固成型后，再将反吊结构拆除；本发明的反吊支撑结构具有抗冲击能力强，搭设过程方便，对水闸运营情况依赖性弱，对水闸墩结构影响小，模板结构可靠性高：反吊支撑结构组成简单，力学体系可靠；经济效益高的特点。
