The invention discloses a steel structure construction platform comprising a supporting column and a lifting platform. The supporting column is hollow. Vertical passageways are arranged on the supporting column. Each vertical passageway communicates with clamping grooves. The lifting platform comprises an annular body and supporting arms. The supporting arms penetrate through the corresponding vertical passageways and can be clamped together with the clamping grooves. The ends, away from the annular body, of the supporting arms are connected together and are fixedly connected with one end of arotating shaft. A lock column is further arranged in the supporting column. The supporting arms all penetrate through the side wall of the lock column. The bottom ends of the supporting arms are fixedly connected with a bottom plate. A motor is arranged on the bottom plate. A driving gear on an output shaft of the motor is engaged with a driven gear on the rotating shaft. A slide block which is in sliding fit with a vertical second slide groove in the inner wall of the supporting column is fixedly arranged on the edge of the bottom plate. A winch is fixedly arranged at the top end of the supporting column. A steel wire rope on the winch is fixedly connected with the lock column. The lifting platform of the steel structure construction platform can be stably fixed to the supporting columnwithout shaking, and the safety coefficient is high.
