step four: the refrigeration house plate (1) is fixed; after the refrigeration house plate (1) and the corresponding n-shaped hanging pieces (3) are completely twisted, the positions of the n-shaped hanging pieces (3) are adjusted, the rabbet of the long edge of the refrigeration house plate (1) is tightly butted with the adjacent refrigeration house plate (1), the upper ends of the n-shaped hanging pieces (3) are fixedly connected with the upper flange of the keel (2) by the self-tapping screw (5), and the side surfaces of the n-shaped hanging pieces (3) and the web plate of the keel (2) are fixedly connected by the self-tapping screw (5) with the wrong tail by the Z-shaped positioning plate;
step five: hoisting a sealing joint hoisting piece (9); lifting a heat insulation lifting hook (8) with a seam sealing hanger (9) hooked at the lower end to the lower side of the refrigeration house plate by using a light winch, tensioning the seam sealing hanger (9) upwards to ensure seamless contact between a sealing strip (18) and the refrigeration house plate (1), and filling foamed polyurethane (17) in a gap between the refrigeration house plates;
step six: the splicing seam (7) is closed; after the foaming polyurethane (17) is hardened, a seam sealing steel plate (10), a base plate (12) and a first gasket (13) are sequentially installed and sleeved on a thread section (82) of the heat insulation lifting hook (8), and then a lifting hook nut (11) is screwed on, so that the construction of the reverse installation construction process node for the suspended ceiling of the refrigeration house plate is completed.
