Abstract
As an important development direction of modern building industrialization, the joint connection performance of prefabricated building is directly related to the stability, safety and durability of the whole structure. This paper focuses on the research of the joint connection performance of prefabricated buildings, and aims to provide theoretical basis and technical support for improving the quality and performance of prefabricated buildings by deeply discussing the types, characteristics and application effects of joint connection technology in practical projects. This paper summarizes the diversity and importance of node connection technologies in prefabricated buildings. The joint connection technology of prefabricated buildings mainly includes dry connection and wet connection. Dry connection, such as bolt connection and welding connection, has the advantages of convenient construction and less wet operation on site. The wet connection, such as cast-in-place connection, realizes the close connection between the members by pouring concrete, and has the characteristics of high connection strength. These connection technologies not only affect the mechanical properties of building structures, but also directly affect the construction efficiency and construction cost. In this paper, the performance characteristics and application range of different node connection technologies are analyzed in detail. By comparing the principle, construction technology and mechanical performance of various connection technologies, the advantages and disadvantages of various connection technologies under different working conditions are revealed. For example, although the construction of bolt connection is convenient, it is necessary to pay attention to the strength and fatigue of bolts; The welded connection has the advantages of strong connection and good structural rigidity, but its seismic performance should be considered under extreme conditions such as earthquake. This paper summarizes the importance and future development direction of research on the joint connection performance of prefabricated buildings. With the continuous advancement of construction industrialization, prefabricated buildings will become the mainstream trend in the future construction field. Therefore, in-depth research on the joint connection performance of prefabricated buildings is of great significance for improving the overall performance of building structures and promoting the transformation and upgrading of the construction industry. In the future, with the continuous emergence of new materials and new technologies, node connection technology will also continue to innovate and improve, providing more possibilities for the development of prefabricated buildings.
