Pushing combination beam

The utility model relates to the technical field of beam body structures, in particular to a pushing combination beam which comprises a first connecting plate, a first pushing plate and a second pushing plate are welded to the two ends of the bottom face of the first connecting plate respectively, and reinforcing connecting blocks are welded to the front ends and the rear ends of the first pushing plate and the second pushing plate together. A plurality of reinforcing ribs are welded to the top face of the first connecting plate, a second connecting plate is welded to the top faces of the reinforcing ribs, and a structure lengthening body is connected to the top face of the second connecting plate. By arranging the second connecting plates, the threaded blind holes, the structure lengthening bodies, the threaded through holes and the screws, the combined beam is convenient to transport, and when the structural length of the combined beam needs to be lengthened, the combined beam can be directly connected with
