Construction method for preventing mixed pouring of high-grade concrete and low-grade concrete
The invention discloses a construction method for preventing mixed pouring of high-grade concrete and low-grade concrete, which comprises the following steps of: installing air bags, and after beam-column joint steel bars are bound, placing a plurality of uninflated air bags in gaps among the steel bars; inflating, namely communicating the air conveying branch pipes of the row inflating pipes with the inflating ports of the air bags one by one, and inflating the air bags through the air conveying main pipe of the row inflating pipes; pouring high-grade concrete, making the air bags expand after being inflated to compactly fill gaps between the steel bars, and then pouring high-grade concrete of the beam column joints; pouring low-grade concrete, after the high-grade concrete is condensed, air in the air bag is released, so that the air bag is shrunk and is separated from the high-grade concrete, the low-grade concrete is poured after the air bag is pulled out, and the low-grade concrete and the high-grade concrete are connected together; and recovering the air bag, cleaning and recovering the air bag for later use.
本发明公开了一种防高低标号混凝土混浇的施工方法，包括下列步骤：安装气囊，梁柱节点钢筋绑扎完毕后，在钢筋间的缝隙中安放多个未充气的气囊；充气，将联排充气管的输气支管一一连通气囊的充气口，然后通过联排充气管的输气总管向多个气囊充气；高标号混凝土浇注，气囊充气后膨胀将钢筋间的缝隙填塞密实，然后浇注梁柱节点高标号的混凝土；低标号混凝土浇注，等到高标号混凝土凝结，将气囊中的气体放出使气囊收缩并与高标号的混凝土脱离，拔出气囊之后再浇注低标号的混凝土，使低标号的混凝土和高标号混凝土连接在一起；回收气囊，清洗并回收气囊，留以待用。
