Cast-in-place construction method for pre-tensioning prestressed precast beam
The invention discloses a cast-in-place construction method for a pre-tensioning prestressed precast beam. The cast-in-place construction method for the precast beam comprises the following specific steps that S1, construction preparation is conducted; s2, placing the steel strands and the stirrups; s3, steel strands are laid and tensioned; s4, installing a beam end mold; s5, steel bars are manufactured and bound; s6, side formwork installation; s7, concrete pouring, wherein concrete is poured through a hopper or an automobile pump; s8, formwork removal, beam lifting and hoisting are conducted; a prestressed beam production line is arranged on site, a high-strength concrete plate strip is adopted as a table top for production and resistance to huge tension, the production efficiency is improved to the maximum extent, the one-time input cost is reduced as much as possible by selecting a permanent and temporary combination mode with an original road, and the problem of quality guarantee of precast beams produced on site is solved; the construction period of the pre-tensioning method prestressed precast beam is relatively short, the engineering task can be completed more quickly, and the construction cost is reduced.
本发明公开一种先张法预应力预制梁现场浇筑施工方法，预制梁现场浇筑施工方法具体步骤如下：S1：施工准备；S2：钢绞线与箍筋摆放；S3：钢绞线铺设与张拉；S4：梁端模安装；S5：钢筋制作和绑扎；S6:侧模安装；S7:混凝土浇筑，混凝土采用料斗或汽车泵浇筑；S8:拆模、起梁与吊装；本发明现场设置预应力梁生产线，采用高强混凝土的板带作为生产及抵抗巨大张拉力的台面，最大程度提高生产工效，且选择与原道路永临结合的方式尽量降低一次投入成本，解决现场生产预制梁质量保证的难点，先张法预应力预制梁的施工周期相对较短，能够更快地完成工程任务，减少施工成本。
