The polyurethane heat-insulating layer is provided with a first polyurethane supporting block 3, a second polyurethane supporting block 4 and a polyurethane heat-insulating composite layer which are aligned at equal heights. The first polyurethane supporting block 3 is aligned with the upper edge of the gap and is positioned at the upper side of the gap, and the second polyurethane supporting block 4 is aligned with the lower edge of the gap and is positioned at the lower side of the gap.

In particular, the first polyurethane supporting block 3 and the second polyurethane supporting block 4 may be formed in the form of in-situ spray foaming.
In this embodiment, the polyurethane thermal insulation composite layer is provided with a polyurethane filling layer 5 and a height limiting prefabricated plate layer 6, and the polyurethane filling layer 5 is sprayed and foamed on site and is embedded between the height limiting prefabricated plate layer 6 and the polyurethane cyanide condensate vapor barrier layer 2.

The first outer color steel plate 7 and the second outer color steel plate 8 are fixed through a keel frame 9 which is perpendicular to the foundation wall 1. The galvanized steel cover plate 11 is connected between the lower end part of the first outer color protection steel plate 7 and the top end of the refrigeration house floor slab 10 through the fastening bolt and is used for shielding the gap and preventing sweeps or dripping water from falling into the gap, so that the heat insulation effect of the heat insulation structure in the gap is lost due to humidity. The upper end of the second outer color protection steel plate 8 is connected with the bottom end of the refrigeration house floor 10 through a fastening bolt to form a right-angle positioning piece 12 for positioning.

Meanwhile, polyurethane is sprayed in the limiting space to form a filling layer, so that the requirement of realizing any design thickness is met.
In addition, in this embodiment, the galvanized steel cover plate 11 is bent upwards to form a certain inclination angle with the horizontal plane at the top end of the refrigeration house floor slab 10, and the specific inclination angle can be 20-35 degrees, so that the accumulation of scraps or water drops in the refrigeration house floor slab is avoided.
