Grouting plugging device for precast hollow column

ActiveCN224413148USimple structureeasy to operatePipeHollow core
The application discloses a grouting plugging device for a prefabricated hollow column, which comprises a grouting plate used in cooperation with a grouting hole reserved for the hollow column and a plugging plate used in cooperation with the grouting hole; the grouting plate and the plugging plate are detachably fixedly connected, and the grouting plate is provided with a grouting plate opening hole used in cooperation with the grouting hole; the grouting plugging device for the prefabricated hollow column is characterized in that the grouting plate and the plugging plate are detachably connected; when the hollow column is grouted, the grouting plate is used in cooperation with the reserved grouting hole for grouting treatment; when plugging is needed, the plugging plate is used in cooperation with the reserved grouting hole for plugging, which is equivalent to the traditional grouting plugging mode of a reserved grouting pipe; the technical scheme is characterized in that the structure is simpler, the operation is more convenient and faster, construction materials are saved, and the demand for standardized construction is improved.
