Abstract: In order to ensure the construction convenience of prefabricated PC structure nodes, application research is carried out on the connection nodes of PC frame structures currently encountered. From the perspective of construction, the connection nodes of prefabricated columns and beams, prefabricated columns and cast-in-place beams, cast-in-place columns and prefabricated beams, prefabricated beams and prefabricated beams, prefabricated beams and cast-in-place beams, cast-in-place beams and prefabricated beams, prefabricated slabs and prefabricated beams, prefabricated slabs and prefabricated slabs, prefabricated slabs and cast-in-place beams, prefabricated exterior walls and surrounding cast-in-place structures, and local node construction of composite layers are summarized in depth. The construction methods of some nodes are summarized from the perspective of construction. Technical iterations have been conducted.Research and practical applications have shown that the above-mentioned connection nodes have basically covered all the connection node construction of prefabricated PC frame structures. For new connection PC nodes that have not yet been encountered, reference methods are also provided, which have reference value for peers.
