Description

Technical Field

[0001] The utility model relates to the technical field of cold storage, in particular to a composite structure of a heat-insulating partition wall of a cold storage. Background Art

[0002] At present, in the use of larger cold storages, it often occurs that the goods stored in the warehouse are not full, or even very few. In this way, overall refrigeration is carried out in the entire cold storage space, wasting energy. Therefore, it is necessary to set up heat-insulating partition walls in the cold storage to divide the cold storage space. If a new civil engineering wall or other base surface is built in the cold storage, it is time-consuming and laborious, and the space layout is not flexible either. There are also existing ones that directly use polyurethane sandwich panels as partition walls, but the polyurethane sandwich panels have poor stability, and there are also gaps between the panels and the ground and between the panels, which are likely to cause cold leakage and affect the heat-insulating effect. Content of the Utility Model

[0003] In order to solve the technical problems mentioned in the background art, the utility model provides a composite structure of a heat-insulating partition wall of a cold storage.

[0004] The utility model adopts the following technical scheme: a composite structure of a heat-insulating partition wall of a cold storage, including a number of upright columns arranged at intervals; a bottom plate is arranged at the bottom of the upright columns; the bottom plate is fixedly connected with the ground by expansion bolts, and an adiabatic interlayer is arranged between the bottom plate and the ground; a number of first transverse keels are fixedly arranged on the inner side between adjacent upright columns, and a first protective plate is arranged on the outer side; the first protective plate is fixedly connected with the first transverse keels by self-tapping screws; the vertical distance between a number of first transverse keels is 800 - 1000 mm; a spacing mechanism parallel to the ground is arranged on each first transverse keel; the transverse distance between adjacent spacing mechanisms is 1000 - 1200 mm; the other end of the spacing mechanism is connected to a second transverse keel; a second protective plate is connected to the outer side of the second transverse keel; the second protective plate is arranged opposite to the first protective plate, and the height of the second protective plate and the first protective plate is adapted to the height of the upright columns; a first polyurethane heat-insulating layer is formed by stratified spraying on the inner side of the first protective plate; a second polyurethane heat-insulating layer is formed by on-site pouring between the first polyurethane heat-insulating layer and the second protective plate.

[0005] Further, the arrangement spacing of the upright columns ≤ 2000 mm.

[0007] Further, the thickness of the first polyurethane heat-insulating layer is 50 - 200 mm.

[0008] Further, the thickness of the second polyurethane heat-insulating layer is 50 - 80 mm.

[0009] Compared with the prior art, the advantages of the present utility model are as follows:

[0010] The composite structure of the cold storage thermal insulation partition wall designed by the present utility model does not require the construction of a civil engineering wall surface or the like inside the cold storage. It can divide the cold storage into several spaces and refrigerate each space separately, saving a large amount of energy. The partition wall has better stability and heat preservation performance. The inner wall of the partition wall is formed by combining a protective plate, columns and transverse keels to form a stable base surface. A first polyurethane thermal insulation layer is sprayed in layers on the base surface, and a second polyurethane thermal insulation layer is poured on-site between the first polyurethane thermal insulation layer and the second protective plate. The seamless connection between the internal thermal insulation structures avoids the cold bridge phenomenon. Brief Description of the Drawings
