Connecting structure of steel beams

The invention discloses a connecting structure of steel beams, and relates to the technical field of connecting structures. The device comprises a device body, a base is arranged at the bottom of the device body, a mounting assembly is arranged on the left side of the device body, an electric telescopic column is hinged to the edge of the front face of the mounting assembly, an adhesion wheel is rotatably mounted in the telescopic end of the electric telescopic column, and a reset piece is fixedly mounted between the top slope of the electric telescopic column and the top of the mounting assembly; the left side of the mounting assembly is provided with an anti-deviation device used for preventing materials from falling off the preassembled track. Oxides generated in the process that the outer walls of materials are repeatedly used for a long time and placed outdoors are subjected to rotary adhesion through the adhesion wheels, the cleanliness of the materials is guaranteed, and the connection strength and sta
