[0002] Steel structure beams and columns are structures made of steel materials and are one of the main types of building structures. They have the advantages of high strength, light weight, good seismic resistance, high degree of industrialization, energy saving and environmental protection. In the construction of some greenhouses, steel structure beams and columns are usually used as supports. When connecting steel structure beams and columns, a connecting structure is required to connect the steel structure beams and columns.

[0003] Chinese patent document CN117051990B discloses a steel structure beam-column connection structure and a steel structure, including a beam-column body, a sleeve, an I-beam connector and a nut, etc. The sleeve is fixedly installed on the beam-column body, and an I-beam connector that can be plugged with the sleeve is provided next to the sleeve. Nuts are symmetrically fixedly installed in the beam-column body, and the sleeve is connected to the two nuts. The I-beam connector is fixed by connecting the nut to the threaded rod, and when the threaded rod is screwed, the push block is pushed by the rigid gasket, so that the wedge-shaped push block drives the limit block in the direction away from each other and is inserted into the corresponding limit groove, so as to provide additional reinforcement between the I-beam connector and the sleeve, thereby preventing the I-beam connector from loosening.

[0004] However, in the above solution, after the sleeve and the I-beam connector are plugged in, they need to be fixed at two locations by threaded rods, which is not convenient for rapid installation of the steel structure beams and columns, and reduces the installation efficiency.
