[0002] Prefabricated buildings refer to buildings that transfer a large amount of on-site work in traditional construction methods to factories. Building components and accessories are processed and manufactured in factories, transported to construction sites, and assembled and installed on site through reliable connection methods. In the initial stage, supporting steel frames need to be installed to ensure subsequent installation and fixation.

[0003] When installing existing supporting steel frames, multiple steel frames need to be connected using connectors to ensure the connection between the steel frames. However, the existing connectors are generally standard parts. During the specific construction process, the connection angles are fixed and cannot adapt well to the needs of specific construction. After the construction is completed, a certain amount of stress remains inside. Under external interference, it is easy to cause damage to the steel frame, thereby making the building unstable and even producing more adverse effects, which cannot guarantee subsequent use well.
