充气模施工技术用之于拱结构、穹顶结构和其它壳结构不但能简化模板工程,还能降低模板费用。使用充气模施工时,可以先给模充气,混凝土可在模内,也可在模外浇注;还可在模充气前布置钢筋并浇注混凝土与平模上。混凝土可以摊铺,但最常 The use of inflatable mold construction techniques for arch structures, dome structures, and other shell structures not only simplifies formwork, but also reduces formwork costs. When using the inflatable mold, the mold can be inflated first, and the concrete can be poured in the mold or outside the mold; the steel can also be placed in the mold and poured onto the concrete and flat mold. Concrete can be paved, but most often
