Frame structure column, beam and plate secondary pouring concrete crack prevention method
The invention discloses a frame structure column, beam and plate secondary pouring concrete crack prevention method, a concrete pouring process and a concrete curing process comprise a mold entering stage, a pouring and tamping stage, a plastering stage, an initial curing stage, a middle curing stage and a later curing stage, and corresponding measures for avoiding generation of cracks are taken for each process; the crack prevention method is mainly suitable for a beam body structure in which a frame structure column, a beam and a plate are poured twice, before pouring, pouring construction organization and arrangement are made twice, after column concrete pouring, beam and plate steel bar binding and water and electricity installation pre-burying operation is carried out every other day, the pouring interval time of the column, the beam and the plate is shortened, and the construction efficiency is improved. And cracks caused by inconsistent concrete shrinkage of the beam-column structure are reduced.
本发明公开了一种框架结构柱与梁、板二次浇筑混凝土裂缝预防方法，所述混凝土浇筑过程及养护过程包括入模阶段、浇捣阶段、抹面阶段、养护初期、养护中期、养护后期，针对每个过程采取相应避免裂缝产生的措施；该裂缝预防方法主要适用于框架结构柱与梁、板分两次浇筑的梁体结构，浇筑前，先做好两次浇筑施工组织与安排，在柱混凝土浇筑后，隔天进行梁、板钢筋绑扎及水电安装预埋作业，缩短柱与梁、板浇筑间隔时间，减少梁柱结构混凝土收缩不一致产生的裂缝。
