Wall column beam joint concrete pouring construction method with different strength grades
The invention discloses a wall column beam joint concrete pouring construction method with different strength grades, in the concrete pouring process, stubble blocking air bags are used for separating concrete with different strength grades, after inflation, the stubble blocking air bags are limited and fixed on limiting steel bars, the section of a formwork is filled, and pouring and vibrating of concrete with different grades on the two sides are completed; before initial setting of the concrete on the two sides, the stubble blocking air bags are deflated and pulled out, and then the concrete at the positions where the stubble blocking air bags are placed is subjected to secondary vibration compaction. The stubble blocking air bags are used for isolating concrete of different strength grades, the concrete of different strength grades is combined into a firm whole by drawing out the stubble blocking air bags in the later period and conducting secondary vibration, and the leakage phenomenon is prevented. And meanwhile, the problems of quality accidents and potential safety hazards caused by the fact that a high-grade concrete member does not meet the strength of the design requirement and material waste and construction cost increase caused by the fact that a low-grade concrete member exceeds the strength of the design requirement are solved.
本发明公开了一种墙柱梁节点不同强度等级混凝土浇筑施工方法，在混凝土浇筑过程中，采用拦茬气囊分隔强度等级不同的混凝土，充气后，拦茬气囊被限制固定在限位钢筋上，填满模板截面，完成两侧不同标号混凝土浇筑及振捣，在两侧混凝土初凝前，对拦茬气囊放气并拔出，然后对拦茬气囊放置位置处的混凝土进行二次振捣密实。本发明使用拦茬气囊隔离不同强度等级的混凝土，通过后期抽出拦茬气囊并进行二次振捣使不同强度等级的混凝土结合成牢固的整体，防止出现渗漏现象。同时避免了高标号混凝土构件不满足设计要求的强度带来的质量事故及安全隐患以及低标号混凝土构件超过其设计要求的强度带来的材料浪费及施工成本增加的问题。
