In order to keep a certain low temperature in the cold storage, the walls, floors and flat roof of the cold storage are laid with a certain thickness of heat insulation material to reduce the heat transferred from the outside. To reduce the absorption of solar radiation energy, the surface of the outside wall of cold storage is usually painted white or light color. Therefore, the cold storage building is different from the general industrial and civil buildings and has its unique structure.
Cold storage building to prevent water vapor diffusion and air penetration. Outdoor air intrusion not only increase the amount of consumption of cold cold storage, but also to a room to the water, moisture condensation cause freeze damage to the building structure, especially heat insulation structure be affected with damp be affected with damp, so to set up the dampproof insulating layer, the cold storage architecture has good sealing and moistureproof gas insulation performance.
The foundation of cold storage is affected by low temperature, and the water in the soil is easily frozen. Due to the volume expansion after soil freezing, the ground will be broken and the whole building structure will be deformed, which will seriously make the cold storage unusable. For this reason, in addition to effective heat insulation layer, the ground floor of cold storage must be treated under the heat insulation layer to prevent soil freezing.
The bottom plate of the cold storage should be piled up with a large number of goods, and it should pass all kinds of loading, unloading and transportation machinery equipment. In low temperature environment, especially in periodic freezing and melting cycle, the building structure is vulnerable to damage. Therefore, the building materials of the cold storage and the construction of each part of the cold storage should have enough anti-freeze performance.
Generally speaking, the cold storage building ensures the quality of the building with its strict heat insulation, sealing, firmness and antifreeze.
