This construction method requires multiple processes such as formwork erection, steel bar binding, and concrete pouring at the construction site. The construction process is extremely complex. Therefore, prefabricated buildings have emerged. In this construction method, concrete structural components are fabricated and formed in a prefabricated component factory, and then transported to the construction site for hoisting and positioning, and then spliced on-site to form an integral structure. Currently, the most commonly used joint connection method in the field of prefabricated buildings is straight thread sleeve grouting connection.
