[0037] Please refer to the following: Figures 1 to 6 The following describes the connection structure between the prefabricated building floor slab and wall panel provided in the embodiments of this application.
[0038] Please see Figures 1 to 6 This application provides a prefabricated building floor and wall panel connection structure, including a lower wall panel 10, a floor panel 20 and an upper wall panel 30.
