The invention discloses a framework with a cast-weld integral structure. The framework comprises two side beams and a plurality of transverse beams, each transverse beam adopts a steel pipe, and the side beams are both of an integral cast structure; the sides, near the transverse beams, of the side beams are each provided with insertion holes with the same number as that of the transverse beams, the two ends of each transverse beam are inserted into the corresponding insertion holes, and assembly welding connecting is performed on the insertion positions of the transverse beams and the insertion holes; each transverse beam is connected with a plurality of hanging seats in a welded mode. By adopting the structure, due to the fact that the side beams are of the integral cast structure, the side beams can be concentratedly cast and applied by a matching supplier and can be supplied quickly, in batches and in low cost. Each transverse beam adopts the steel pipe and is easy to obtain, and when the requirements of different projects for the track gauge are different, steel pipes with a certain length only need to be selected or existing steel pipes are cut into the steel pipes with the needed length. Assembly welding does not need to be performed on various plates complexly, a busy welding production line does not need to be occupied, the manufacturing cost is low, the design cycle and the production cycle are both shorter, and the goods can be quickly delivered.
