The invention relates to the technical field of bridge reinforcement cage hoisting construction, in particular to a simply supported beam movable formwork cast-in-place construction method for integrally hoisting a reinforcement cage into a formwork, which comprises the following steps: S1, splicing a movable formwork above a poured box girder, S2, binding the reinforcement cage corresponding to the first section of box girder in the cast-in-place formwork, and pumping concrete for pouring, and S3, carrying out cast-in-place construction on the first section of box girder in the cast-in-place formwork. S4, the reinforcement cage jig frame is disengaged through the reinforcement cage binding frame, and the reinforcement cage jig frame serves as a balance weight; s5, the front supporting leg penetrates through the cast-in-place formwork and slides into the front auxiliary supporting leg, and the front supporting leg and the pier are anchored again; and S6, the bottom frame of the cast-in-place formwork is combined towards the middle in place, box girder pouring, front span concrete pouring, curing, tensioning, rear span synchronous reinforcement cage binding and inner formwork mounting corresponding to the next section are conducted, the steel bar procedure and the concrete procedure are conducted in parallel, the reinforcement cage does not need to be transported and hoisted, and the construction efficiency and safety are improved.

    本发明涉及桥梁钢筋笼吊装施工的技术领域,具体涉及钢筋笼整体吊装入模的简支梁移动模架现浇施工方法,包括:步骤S1,在已浇筑箱梁上方拼接移动模架,步骤S2,在现浇模架内进行首段箱梁对应的钢筋笼绑扎,泵入混凝土进行浇筑,步骤S3,待首段箱梁混凝土到达预设强度后进行预应力张拉,步骤S4,通过钢筋笼绑扎架将钢筋笼胎架脱空,以作为配重;步骤S5,前支腿自现浇模架内穿过并滑移至前辅助支腿内,并与桥墩重新锚固;步骤S6,现浇模架的底架向中部合并就位,进行下一节段对应的箱梁浇筑,前跨浇筑混凝土、养护、张拉,后跨同步绑扎钢筋笼并安装内模,实现钢筋工序与混凝土工序并行,无需进行钢筋笼运输与吊装,提高施工的效率和安全性。
