The present invention relates to a composite girder connected and installed in between pillars when building a structure that is made in a shape of a unit with a certain length where structural steel and concrete are combined and, more specifically, relates to a composite girder where the structure to apply an H-shaped structural steel for an entire length of the girder is avoided; the H-shaped structural steel applied to only a part of both end units of the girder; a concrete accommodating unit in the shape of a pocket comprising a first pocket steel plate and a second pocket steel plate connected to be a single body in between a top flange and a bottom flange on both sides of a vertical central area of the H-shaped structural steel; the top surface of the concrete accommodating unit distanced downward for a certain interval from the top flange of the H-shaped structural steel to be formed on a lower height than the top flange of the H-shaped structural steel; a supporting unit formed using a supporting piece made by extending a top end unit of the concrete accommodating unit to protrude to the outside, a binding fixture to support and bind that, and a supporting piece support fixture; and on a bottom end of a second pocket steel plate, a plurality of long and short binding pieces placed to be distanced in a longitudinal direction of the girder. |
