Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a freezer / refrigerated warehouse, and more particularly to a freezer / refrigerated warehouse in which a lower structure of a casing and a ventilation layer are formed at low cost.
[0002]
[Prior art]
In recent years, refrigeration / freezer warehouses whose construction has been demanded due to the demand for the spread of frozen foods and the like are composed of a refrigeration section and a cargo handling section. In conventional refrigerated and frozen warehouses, along with heat insulation design for indoor cold insulation, the cold heat passes through the heat insulation material over a long period of time and is transmitted to the concrete slabs, underground beams, and foundations in the lower part of the frame, and in the soil such as chestnuts The problem of preventing the frost heaving phenomenon that has an impact on the environment has been greatly highlighted.
[0003]
In other words, because the thermal insulation layer also has thermal conductivity, cold heat is transmitted to the structure on its side in a long period of time, freezing the concrete structure slabs, underground beams, foundation slabs etc. As a result, water such as sand, clay, gravel, etc. in the soil in contact with these parts is frozen. These freezing and expansion are absorbed downward in the soil at the initial stage, but when freezing proceeds deep into the ground, the freezing and expansion due to earth pressure comes out to the ground surface and resists structural loads. As a result, the frost heaving phenomenon that pushes up the above-mentioned soil concrete, underground beams and the like is developed, and in an extreme case, the floor of the warehouse is unevenly raised and becomes unusable.
[0004]
In order to prevent these frost heaving phenomena, conventional freezer / refrigerated warehouses are provided with vent holes in the surrounding and internal fabric foundations or foundation beams to replace the cold air under the floor with the outside air.
[0005]
FIG. 6 shows an example thereof . The refrigeration / freezer warehouse 20 is composed of a refrigeration unit 21 and a cargo handling unit 22, and a floor board 23 of an appropriate thickness also serving as a foundation is interposed through a ventilation layer 24. Is in contact with the ground. The ventilation layer 24 of this example is formed by laying a deck plate 25 on the lower surface of the floor plate 23. An air supply groove 26 is provided at one end of the ventilation layer 24 and an exhaust groove 27 is provided at the opposite end. Provided. Further, a heat insulating material 28 is provided between the floor plate 23 and the deck plate 25, and an exhaust fan 29 is provided in the exhaust groove 27 to be connected to a ventilation pipe (not shown).
[0006]
The cool air accumulated in the ventilation layer 24 of the floor plate 23 is sucked into the exhaust groove 27 by the exhaust fan 29 and exhausted to the outside, and at the same time, fresh air is sucked into the air supply groove 26 from the air supply port . The air in the ventilation layer 24 is constantly circulated without being retained, thereby forming a heat insulating layer in the refrigeration unit 21 to prevent the ground from freezing.
[0007]
However, as shown in this example, a floor board that also serves as a foundation is provided to constitute the lower part of the frame, and the deck plate is laid on the entire surface under this floor board and the heat insulating material is laid separately. In short, it was a factor that increased the overall cost of building a freezer / refrigerated warehouse.
[0008]
[Problems to be solved by the invention]
The present invention is provided in view of the above situation, freezing and refrigeration for preventing the frost heaving phenomenon of the ground by forming an efficient heat insulating layer while simplifying the structure of the lower part of the housing and the formation of the ventilation layer. A warehouse is provided.
