The invention belongs to the technical field of box girder steel models, and particularly relates to a rotatable single-line box girder steel model and a demolding method thereof. According to the technical scheme, the rotatable single-line box girder steel model comprises a bottom form arranged on a foundation, wherein side forms are arranged on the two sides of the bottom form, a plurality of bent frames are fixed to the side forms, and end forms are connected between the end part of the bottom form and the end parts of the two side forms; internal supporting legs and external supporting legs are arranged at the bottoms of the bent frames, the internal supporting legs of the bent frames on at least one side are hinged to the foundation, and lifting mechanisms are connected between the external supporting legs of the bent frames hinged to the foundation and the foundation; and when only the internal supporting legs of the bent frames on one side are hinged with the foundation, the internal supporting legs an
