Prestressed concrete variable cross-section box girder hanging basket suspension casting construction method
The invention relates to a prestressed concrete variable cross-section box girder hanging basket suspended pouring construction method. The method comprises the following steps that a walking system is installed on the top face of a poured box girder; upper cross beams are installed on the upper portion of the main truss, lower cross beams are hung below the upper cross beams through suspenders, and lower longitudinal beams are installed between the lower cross beams; a bottom plate formwork is installed on the lower longitudinal beam, a steel wire rope is wound and unwound through a steel wire rope unwinding device, the side formwork and the inner formwork of the box girder are hoisted in sequence, then a new box girder is poured, a sliding rail is laid on the top face of the new box girder, and construction of all the box girders is completed repeatedly. The method has the advantages that the steel wire rope and the steel wire rope pay-off device are adopted to replace a suspender, nut and double-nut anchoring structure, the height of the inner and outer sliding beams is adjusted more conveniently, the inner and outer formworks can be replaced quickly, and the cross section of the box girder can be changed.
本发明涉及一种预应力混凝土变截面箱梁挂篮悬浇施工方法，包括以下步骤：在已浇筑的箱梁顶面安装走行系统；在主桁架上部安装上横梁，上横梁下方通过吊杆吊挂下横梁，下横梁之间安装下纵梁；在下纵梁上安装底板模板，通过钢丝绳放线装置收放钢丝绳，依次吊装箱梁的侧模和内模，然后浇筑新的箱梁在新的箱梁顶面铺设滑轨，重复完成所有箱梁的施工。本发明的有益效果是：采用钢丝绳和钢丝绳放线装置替代吊杆、螺帽和双螺母锚固的结构，调节内外滑梁的高度变得更为方便，有利于快速更换内外模板，实现箱梁截面的可变。
