Description

Cold storage full steam insulation dry operation internal insulation system

technical field

The utility model relates to an internal thermal insulation system of a cold storage, in particular to an internal thermal insulation system and a construction method thereof for full steam insulation and dry operation of the cold storage.

Background technique

With the development of cold chain logistics, the construction speed of cold storage in my country has been advancing by leaps and bounds in recent years. The National Development and Reform Commission recently announced the "Agricultural Products Cold Chain Logistics Development Plan". As the cost of refrigeration energy consumption accounts for nearly 50% of personal expenses, the interior of the cold storage is characterized by high humidity and low temperature, and the performance of heat preservation, heat insulation, waterproof, and vapor insulation of the enclosure structure has a crucial impact on reducing operating energy consumption . Compared with ordinary civil and industrial buildings, the interior of the cold storage is a closed space. Once a fire occurs, the smoke is not easy to spread, and there is no convenient escape route for personnel. Therefore, the consequences of a fire in the cold storage are particularly serious. However, there is a lack of research on the application technology of cold storage insulation. For a long time, there has not been a good system to solve the problems of cold storage insulation, steam insulation and fire prevention. At present, the thin plastering system and the on-site hard foam polyurethane spraying system mainly use extruded board as insulation materials. There are the following question:

(1.) When installing the fixing parts, the vapor barrier layer is destroyed, and there is no complete vapor barrier layer, resulting in serious water vapor leakage during use.

(2.) China has a vast territory, and the storage temperature and temperature will change with the seasons. The one-way high-temperature side steam insulation cannot meet various working environments, causing the insulation material to be damp and the insulation performance to drop sharply.

(3.) When using multi-layer insulation boards, nails need to be fixed layer by layer, which seriously damages the base wall.

(4.) Due to the high humidity environment, only organic thermal insulation materials with relatively small water absorption can be used, and there are no good system fire prevention measures, which brings fire hazards.

(5.) On-site wet construction, the waste of mortar and other materials is serious, and the on-site construction environment is harsh.

Preferably, the inner vapor barrier layer is PE film or paint, and the outer vapor barrier layer is PE film.

The construction method of the internal heat preservation system for the full steam-proof dry operation of the cold storage is characterized in that: firstly, the base wall is accepted, and after the acceptance is passed, the installation head of the fixing part is fixed inside the base wall, so that the shaft of the fixing part is perpendicular to the base wall.

Leading from the base wall, it runs through the inner vapor barrier 2 and the thermal insulation layer 3 successively. The end of the fixing part 6 is connected to the locking part. The outer vapor barrier layer 4 and the protective layer 5 are fixedly connected together by screws. Since the center of the keel has a through hole, the through hole in the center of the keel also passes through the screw, and the keel is connected to the end of the fixture by the screw.

Heart has a screw hole 6-3, disposes screw in the screw hole, and keel is connected together with shaft by screw, and fixing part can use one or several as required in the utility model. The fixing part is made of hard engineering plastics, and the place where the fixing part penetrates the air barrier layer is sealed with an elastic gasket 8 or elastic gasket, and the elastic gasket 8 or elastic gasket is made of elastic organic material , including but not limited to polymer materials such as rubber, silica gel, PVC, polyurethane, EPDM, etc. The thickness of the elastic gasket 8 or elastic pad is 1.5-3 mm, and the installation head can be embedded or pasted. It can be fixed on the base wall, or it can be drilled on the base wall in advance to fix the installation head.

The inner vapor barrier layer can use vapor barrier paint or vapor barrier film. The thermal insulation layer can be a layer of thermal insulation board or a multi-layer thermal insulation board. Staggered laying, horizontal insulation boards and vertical insulation boards between layers are also laid with staggered seams. In short, no matter how they are placed, the opposite seams between insulation boards should not be set together to avoid poor insulation effect. The insulation layer can use organic insulation boards, such as PU, XPS, EPS, etc., or inorganic insulation boards, such as mineral wool boards, rock wool boards, glass wool boards, etc.
