PREFABRICATED REINFORCED CONCRETE MODULAR COLUMNS

Abstract

The invention relates to a prefabricated modular reinforced concrete column (1) with a hollow frame structure before monolithic concrete pouring at the site, differing in that it includes: a steel frame (2) composed of four shaped angle steels (21), many evenly spaced steel stirrup elements (22) arranged around the four shaped angle steels (21), positioning plate elements (23) fixed correspondingly to the inner corners of the four shaped angle steels (21) and four main reinforcing bars (24) positioned by positioning plate elements (23); column head box modules (3) and reinforcing base (4) are constructed with a hollow box body and fixed correspondingly at the upper and lower ends of the steel frame (2);The permanent column shell module (5) is fixed around the entire outer perimeter of the steel frame system (2) and consists of a water-retaining mortar plate (51) which is made of multiple layers of finely woven fiberglass mesh so that excess water and air bubbles escape during concrete pouring and retain all the cement paste, and a steel mesh plate to prevent bulging (52) which is installed on top of the water-retaining mortar plate (51).;
