Description

Technical Field

[0001] The utility model relates to the technical field of house assembly, in particular to a modular house dry connection structure. Background Art

[0002] The current challenge facing prefabricated building structures is the node connection problem. Currently, there are two node connection technologies that can be summarized, namely dry node connection technology based on non-wet operations such as bolt connection and wet node connection technology based on pouring concrete in reserved post-casting areas. In the wet node construction method, shear force and bending moment are transmitted at these discontinuous nodes or interfaces, making the new and old concrete interfaces between the joints of prefabricated components a relatively weak link in the prefabricated structure. At the same time, wet connection nodes cannot be connected and used immediately during the construction process, and the production efficiency is low.

However, the assembly connection structure is complicated. Summary of the invention
