Among them, the connection technology of prefabricated wall panels can be divided into wet connection and dry connection according to the construction method. Dry connection is a method of connecting by implanting steel sleeves or embedded parts in prefabricated components through sleeve grouting, bolts or welding. Dry connection has the advantages of higher precision, shortened construction period, easy repair of nodes damaged after earthquake, and convenient installation in remote areas. It is the development trend of prefabricated connection technology in the future.
