Technical Field

[0001] This utility model belongs to the field of prefabricated building technology, specifically relating to the connection structure of prefabricated building modules. Background Technology

[0002] Precast shear wall structures are an important form of prefabricated concrete structures. Existing technologies largely focus on connecting the end faces of adjacent precast concrete walls (i.e., the faces along the height and thickness of the precast concrete walls), with few addressing connections along the height and length of adjacent precast concrete walls. End face connections can only connect single walls, while connections along the height and length can connect rooms (rooms with multiple walls can be prefabricated in the factory), further increasing the degree of prefabrication and reducing on-site work. Summary of the Invention

[0078] In other embodiments, to facilitate the installation of the toothed horizontal steel bar 3, the toothed horizontal steel bar 3 can be inserted into the first steel bar groove 22 / second steel bar groove and leaned against the wall 1 (at this time, it can be operated from the side, and the installation of the toothed horizontal steel bar 3 is easier). Then, the first precast concrete module 01 and the second precast concrete module 02 are hoisted. After being hoisted into place, the toothed horizontal steel bar 3 is rotated so that the horizontal steel bar 3 passing through the first steel bar groove 22 rests on the second connecting block.
