This invention relates to the field of bridge construction technology, and particularly to a steel-concrete composite beam support and its preloading construction method. The steel-concrete composite beam support includes two rows of separate side supports, which are used to symmetrically support the bottom of the side boxes on both sides of the main steel beam. Multiple rows of steel pipe columns are arranged at intervals, and each row of steel pipe columns includes multiple steel pipe columns. Adjacent steel pipe columns are connected by diagonal bracing groove steel frames. A transverse distribution beam is fixed at the top of the multiple rows of steel pipe columns, and a Bailey beam is fixed on the transverse distribution beam.
