The invention provides a multi-purposed building material circular track comprising supporting stand columns evenly fixed on the periphery of a building, rectangular supporting side frames fixed on the supporting stand columns, four circulating leather belts placed on the upper surfaces of the four side plates of the rectangular supporting side frames and rolling wheels rotationally fixed on two ends of the four side plates and supported on the internal surfaces of the top ends of the circulating leather belts. A plane, where the rectangular supporting side frames lie is parallel to the supporting stand columns; the four circulating leather belts are orderly connected; and the front top end of the previous circulating leather belt has a contact with one side of the back end of the back circulating leather belt. By the use of the multi-purposed building material circular track, building material can be stably transported on the circular track via the circulating leather belts; construction workers can easily fetch and put back the building material; and work safety can be enhanced.
