The utility model relates to a section steel concrete conversion structure steel frame of a metro double-column elevated station. Due to limitation of road conditions, a conversion structure needs to be arranged for a metro elevated station, and a common reinforced concrete conversion structure does not have high load-bearing performance and an anti-seismic performance. The section steel concrete conversion structure comprises steel frame column sections, short beams of the steel frame column sections, steel frame cantilever beam sections on two sides and a steel frame middle beam section in the middle, and the short beams are fixed with the steel frame cantilever beam sections and the steel frame middle beam section through steel frame splicing plates and high-strength bolts; a variable-section transition section is arranged on each of the lower portion of the steel frame column sections and the end portions of the steel frame cantilever beam sections; a column rebar connecting plate and a beam rebar connecting sleeve are arranged at a beam-column joint of each steel frame column section, and supporting column joint column rib through hole reinforcing plates and supporting column joint steel frame beam section reinforcing plates are arranged on a beam body at an underpinning column. Components of the section steel concrete conversion structure steel frame are high in bending and shearing resistance, small in deformation and higher in anti-seismic performance, and the section steel concrete conversion structure steel frame has wide application value in the metro double-column elevated station.
