Prefabricated floor slabs are prefabricated concrete parts that are produced and processed in a prefabrication yard and then transported directly to the construction site for installation. Prefabricated walls and prefabricated floor slabs are required during the construction of buildings. The existing prefabricated floor slabs and prefabricated walls are fixed together with bolts. Pre-set holes are opened in the wall in advance, and then internal threaded sleeves are installed in the pre-set holes. The bolts are then passed through the prefabricated floor slabs and the internal threaded sleeves for spiral connection, thereby facilitating the connection of prefabricated walls and prefabricated floor slabs.
[0003] When connecting prefabricated walls and prefabricated floor slabs, the prefabricated walls are placed in a pre-dug foundation pit, and then the prefabricated floor slabs are placed on the prefabricated walls, and then they are connected by the cooperation of bolts and internal threaded sleeves. However, the prefabricated walls are not fixed when placed in the foundation pit, which makes the placement of the prefabricated walls unstable and causes shaking. As a result, when connecting the prefabricated walls and prefabricated floor slabs, the bolts and internal threaded sleeves do not cooperate well, making the connection more difficult.
