The invention relates to the field of structural engineering in civil engineering, in particular to a square covering square hollow sandwiched carbon fiber steel rib-steel pipe concrete combined column. The combined column can save the consumption of concrete, lighten the dead weight of members and reduce the construction difficulty of cast concrete, and has high flexural rigidity and torsional rigidity. The combined column comprises a core steel pipe, concrete, angle steels, an external angle steel, batten plates and carbon fiber cloth; the angle steels with square sections on four angles and the batten plates form an external steel framework; the core steel pipe is placed in the steel framework; the centroid of the square steel pipe can be superposed with that of the steel framework; the concrete is filled between the steel framework and the core steel pipe; and the carbon fiber cloth is wrapped outside a steel pipe concrete column. The concrete is not poured into the steel pipe, so the steel pipe is hollow. According to the combined column, the consumption of materials is saved, the rigidity and the ductility of the members are improved, the construction difficulty in pouring the concrete is reduced, and the combined column has good heat insulation and sound insulation properties.
