Novel internal mold hollow floor concrete pouring construction method
The invention relates to a novel internal mold hollow floor concrete pouring construction method. The novel internal mold hollow floor concrete pouring construction method comprises the following steps that a filling internal mold is prefabricated, and openings are correspondingly formed in the centers of a top plate and a bottom plate of the filling internal mold; a formwork is designed, floor bottom layer reinforcing steel bars are bound, and ribbed beams are bound; fine aggregate concrete cushion blocks are arranged on the paved formwork; the filling internal mold is installed; a mix proportion of concrete is designed, the concrete aggregate size is not larger than 16mm, and the slump of the concrete is controlled between 15cm and 17cm; floor surface layer reinforcing steel bars are paved and the filling internal mold is bound, and the reinforcing steel bars for binding the filling internal mold penetrate from the openings of the filling internal mold to be bound with the floor bottom layer reinforcing steel bars and the floor surface layer reinforcing steel bars; tapping pouring is carried out on the concrete from the center of the filling internal mold, inside and outside of the filling internal mold are simultaneously vibrated, and one-step molding is carried out; and concrete curing is carried out. According to the novel internal mold hollow floor concrete pouring construction method, the problem of the pouring quality of the hollow floor concrete due to uncompacted filling of the filling internal mold bottom plate concrete can be solved, the filling internal mold binding difficulty is reduced, the filling internal mold is effectively prevented from floating, and the pouring efficiency is improved.
本发明涉及一种新型内模空腹楼板混凝土浇筑施工方法，包括以下步骤：预制填充内模，填充内模的顶板和底板中心对应开设有开孔；搭设模板，绑扎楼板底层钢筋，绑扎肋梁；在铺设好的模板上放置细石混凝土垫块；安装填充内模；设计混凝土配合比，混凝土骨料粒径选择不大于16mm，混凝土坍落度控制在15～17cm；铺设楼板面层钢筋并绑扎填充内模，绑扎填充内模的钢筋从填充内模的开孔中穿过与楼板底层钢筋和楼板面层钢筋绑扎；混凝土自填充内模中心开孔浇筑，填充内模内外同时振捣，一次成型；混凝土养护。本发明能够解决因填充内模底板混凝土填充不密实而造成的空腹楼板混凝土浇筑质量问题，降低填充内模绑扎难度，有效防止填充内模上浮，提高浇筑效率。
