Open-web type steel reinforced concrete core column

The utility model discloses an open-web type steel reinforced concrete core column which comprises an inner-layer core column space framework, an outer-layer common column steel bar framework and concrete. The inner-layer core column space framework comprises core column profile steel branches, core column structure longitudinal steel bars, core column structure connecting batten materials and core column annular closed stirrups; the common column steel bar framework comprises common column longitudinal steel bars and common column stirrups. According to the open-web type steel reinforced concrete core column formed by combining the structures, the axial compression ratio limit value can be increased by 0.05 and can be increased by 0.15 to the maximum compared with that of a common reinforced concrete column, the construction steel consumption is about 1/4-1/3 of that of a solid-web type steel reinforced concrete column and a composite column, and the economic benefit is obvious; a space framework of the holl
