Prefabricated components and corresponding accessories of prefabreicated construction are designed in a standardized way and produced in a factory. They are transported to the construction site and then directly installed. The process is relatively simple. This traditional prefabricated building technology has gradually been replaced by the new prefabricated building technology, and has played a significant advantage in today's residential construction. Based on this, the application of new prefabricated technology in residential construction is analyzed.展开更多
