[0002] In the construction field, during the connection process of frame module structures, common module structure connection nodes all require a relatively large operating space to complete the structure connection. Especially for the beam-column corner nodes within the frame module, if bolt connection is adopted, a relatively large operating space is required.

[0003] For fully decorated modules, the internal decoration has been completed, and it is not suitable for large-scale demolition and reconstruction. The available construction space is extremely narrow, and it is particularly difficult to install and operate at the beam-column corner nodes within the frame module. It is very inconvenient to use long bolts for installation. Moreover, in the traditional method, the steel consumption at the module nodes is large and the cost is high. Therefore, it is necessary to develop a simple, fast, and practical installation method for fully decorated modules. Summary of the Invention
