Abstract: The key technology of prefabricated concrete building structure lies in the connection of member nodes. Therefore, a reliable and effective connection technology is a favorable guarantee for the safety and seismic resistance of prefabricated concrete structures. The paper analyzes several common member node connection technologies in engineering and summarizes the advantages and disadvantages of each technology. At the same time, it detail analyzes and elaborates the construction key points of various technologies, to provide reference for the application of prefabricated concrete structure node connection technology.
