[0002] In prefabricated buildings, floor panels and wall panels are prefabricated in factories and then assembled on site. During assembly, the lower wall panels are installed first, and the floor panels are butt-jointed, that is, the two butt-jointed floor panels are hoisted in the lower wall panels, and the butt joints of the floor panels are placed on the wall panels. The upper wall panels are then hoisted on the upper ends of the two butt-jointed floor panels, and the wall panels are placed at the butt joints of the floor panels, and then fixed through connection nodes. The connection nodes between the wall panels and the floor panels generally use PK boxes, screw rods, nuts, embedded sleeves, etc. An embedded sleeve is set inside the upper end of the wall panel (prefabricated with the wall panel in the factory), and a PK box is set inside the lower end of the wall panel (prefabricated with the wall panel in the factory). Before hoisting the floor panel, first install the screw rod in the embedded sleeve in the lower wall panel, then hoist the floor panel so that the screw rod passes through the butt joints between the floor panels and extends out of the upper end of the floor panel, and then hoist the upper wall panel so that the screw rod is inserted into the PK box in the wall panel, and then fastened with nuts. Finally, pour mortar into each gap and PK box to complete the installation.
