Fabricated building beam-column joint connection construction method based on post-tensioning anchoring

The invention discloses a prefabricated building beam-column joint connection construction method based on post-tensioning anchoring, which combines a dry connection mode and a wet connection mode of beam-column joints, and anchors prestressed reinforcements in a tension area at the lower part of a prefabricated concrete beam in a prefabricated concrete column with a pre-embedded positioning steel plate through reserved holes; after the joints are connected on the construction site, grouting treatment is conducted, and the integrity of the structure is guaranteed; the upper compression steel bars of the prefabricated concrete beams are welded to the embedded positioning steel plates in the prefabricated concrete columns, and the stability of the structure is guaranteed. Through the combined action of the prestressed reinforcements in the tension area and the reinforcements in the compression area, the crack resistance and durability of the cross section of the beam column are effectively improved, and the ant
