[0002] With the development of modern industrial technology and the pursuit of higher construction speed, prefabricated and assembled structures are increasingly used in the construction field. Specifically, the corresponding house components are produced in the factory according to the design and manufacturing, and then the prefabricated house components are transported to the construction site for assembly, thereby eliminating the time of pouring concrete on site and waiting for the concrete to solidify, improving the construction speed of the building and reducing production costs. At present, this kind of assembled structure is also increasingly used in the construction of building nodes. Building nodes are generally steel parts used to connect mutually perpendicular steel beams.

The four bottom surfaces of the square sleeve are provided with a first support block, and the first support block is also fixedly connected to the square steel. The prefabricated node structure can effectively improve the connection stability through the connection between the square sleeve and the square steel, and the cooperation between the U-shaped load-bearing groove and the H-shaped steel, thereby avoiding the steel beam from falling off when the connection structure is subjected to unilateral force and causes severe vibration in the prior art, thereby improving the safety of the connection.
