Prefabricated outer wall mounting and connecting structure

The utility model relates to the technical field of connecting structures, and discloses a prefabricated outer wall installing and connecting structure which comprises a frame wall body and a prefabricated outer wall, and two frame wall body embedded parts are fixedly installed in the frame wall body in an up-down aligned mode. And two pieces of second angle iron are symmetrically and fixedly mounted on the outer surface of the frame wall body embedded part close to the top end of the frame wall body. The lead screw drives the sliding block to move along the sliding groove, the sliding block drives the first angle iron and the second angle iron to generate relative displacement, the first angle iron drives the prefabricated outer wall to move through the prefabricated outer wall embedded part, the perpendicularity of the prefabricated outer wall is adjusted, and when the perpendicularity of the prefabricated outer wall is adjusted through the device, only the lead screw needs to be rotated.
