[0030] The present invention facilitates the placement of the purlin 8 into the clamp by means of the downwardly inclined limiting pressure plate 13 of the clamp plate 1. Through the cooperation of the hanger 2 and the locking nut 21, the limiting pressure plate 13 can be pressed against the bottom of the purlin 8, thereby fixing the clamp plate 1 on the purlin 8 without damaging the original structure of the roof. The installation is convenient. The three-dimensional laser scanner is used to scan and generate a point cloud model, which can accurately locate and determine the position of each hanger 2, thereby improving the installation accuracy of the cold storage ceiling. By setting the connecting piece 6, the cold storage ceiling can be separated into two parts for installation.

[0039] Step 2: Install the clamping plate 1 on the purlin 8, and thread the upper end of the suspension rod 2 with the positioning nut 14, and then tighten the locking nut 21 on the suspension rod 2 to press the limiting pressure plate 13 against the bottom surface of the purlin 8;

[0040] Step three, the heat-insulating rubber pad 7 is sleeved on the screw of the connecting screw 4, and the screw head of the connecting screw 4 is placed in the inner cavity of the connecting beam 5, and the screw of the connecting screw 4 passes through the connecting hole to connect with the connecting piece 6, so that the screw head of the connecting screw 4 presses the connecting plate 51 against the bottom surface of the sandwich panel 3; further, in the step three, the connecting screws 4, the heat-insulating rubber pads 7 and the connecting beam 5 on the four sides of the sandwich panel 3 are installed first, and then the connecting screws 4, the heat-insulating rubber pads 7 and the connecting beam 5 in the middle of the sandwich panel 3 are installed to improve the installation efficiency;

[0041] Step 4: inject the thermal insulation foaming agent 32 into the gap of the matching hole 31.
