Inverted trapezoidal variable-section steel pipe concrete column

The invention discloses an inverted trapezoidal variable-section steel pipe concrete column. The inverted trapezoidal variable-section steel pipe concrete column comprises a steel pipe and concrete, wherein the steel pipe is composed of a plurality of inverted right-angled trapezoidal hollow shell bodies located on different floors; the hollow shell bodies are arranged in sequence along an inclined direction; the hollow shell bodies are flat bodies; one side face of each hollow shell body is a vertical surface and the other side face of each hollow shell body is an inclined plane; one end, located at one end of the inclined plane, of a top surface of each hollow shell body is an outer end face; a hole is formed in the bottom of each hollow shell body; the hole formed in the bottom of the hollow shell body located on the last floor is fixed on the outer end face of the top surface of the hollow shell body located on the next floor, so that the inner parts of the adjacent hollow shell bodies are communicated; t
