Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a heat preservation structure suitable for non-adhesion expansion joints of cold storage. Background Art

[0002] With the rapid development of my country's economy, cold storage has been used more and more in national production. Driven by the government's policy encouragement and the strong demand of the fresh food market, the investment and construction of cold storage, as the core infrastructure supporting cold chain logistics, has shown a rapid growth trend.

[0003] The expansion joints between cold storage layers need to be filled with polyurethane insulation, whether from the perspective of safety or insulation effect. However, in the later use process, the cold storage floor is prone to uneven settlement. If the polyurethane insulation layer structure formed by spraying the expansion joint is used as a whole, the outer wall and the inner wall will be tightly bonded together. Under the action of the sedimentation force, it is easy to tear the insulation layer in this part, causing problems such as cold leakage. Utility Model Content

[0006] The second polyurethane insulation layer includes a horizontal polyurethane partition bottom plate adapted to the width of the expansion joint, a vertical polyurethane partition baffle adapted to the height of the expansion joint, and several layers of polyurethane insulation single layers clamped between the horizontal polyurethane partition bottom plate and the vertical polyurethane partition baffle; the horizontal polyurethane partition bottom plate is horizontally arranged between the gap between the inner wall and the outer wall of the cold storage; the vertical polyurethane partition baffle is attached to the surface of the outer wall of the cold storage; several layers of polyurethane insulation single layers are aligned along the height direction of the expansion joint, and a wire mesh layer is laid between two adjacent layers for fixing.

[0007] Furthermore, a cement mortar leveling layer is provided between the inner wall of the cold storage and the cyanide vapor barrier layer.

[0008] Furthermore, the thickness of the polyurethane thermal insulation single layer is 40-60 mm.

[0009] Furthermore, the thickness of the vertical polyurethane partition baffle is 4-5 cm; the thickness of the horizontal polyurethane partition bottom plate is 5-8 cm.

[0010] Compared with the prior art, the advantages of the utility model are:

[0011] The utility model is designed with a non-stick insulation structure suitable for expansion joints of cold storages, wherein the bottom of the second polyurethane insulation layer is supported by a horizontal polyurethane partition bottom plate; the sides of the insulation layer are surrounded by vertical polyurethane partition baffles, and the inner layer is stacked in layers to form an insulation layer structure, while ensuring safety and insulation effects.
