Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to a refrigerated / refrigerated warehouse, and more particularly to a refrigerated / refrigerated warehouse in which a lower structure of a frame and a ventilation layer are formed at low cost.
[0002]
[Prior art]
2. Description of the Related Art In recent years, refrigerated / frozen warehouses whose construction has been demanded due to the demand due to the spread of frozen foods and the like are composed of a refrigeration unit and a cargo handling unit. In conventional refrigerated / frozen warehouses, in addition to the heat insulation design for keeping cool indoors, the cold heat penetrates the heat insulation material over a long period of time and is transmitted to the concrete slab, underground beam, foundation, etc. The issue of prevention of frost heaving, which has an impact on the environment, has been greatly highlighted.
[0003]
In other words, since the thermal insulation layer also has a thermal conductivity, in the long term, cold heat is transmitted to the structural body on that side, and the substructure concrete slab, underground beam, foundation slap, etc. The frozen state is brought about, and the water in the soil, clay, gravel, etc. in the soil in contact with these parts is frozen. Initially, these freezing expansions are absorbed downward into the soil, but as the freezing progresses deeper into the ground, the freezing expansions due to the earth pressure come out to the ground surface and resist the structural load. As a result, the above-mentioned frost heaving phenomenon that pushes up the concrete between the soil, the underground beams, etc. is developed, and in an extreme case, an uneven ridge is generated on the floor of the warehouse, so that the warehouse cannot be used.
[0004]
In order to prevent these frost heave phenomena, a conventional freezing / refrigerated warehouse is provided with ventilation holes around and inside the fabric foundation or foundation beam to replace the cool air under the floor with the outside air.
[0005]
FIG. 7 shows an example thereof. The refrigeration / freezing warehouse 20 includes a refrigeration unit 21 and a cargo handling unit 22, and a floor plate 23 having an appropriate thickness also serving as a foundation is provided via a ventilation layer 24. Is in contact with the ground. The ventilation layer 24 of the present example is formed by laying a deck plate 25 on the lower surface of the floor plate 23, and has an air supply groove 26 at one end of the ventilation layer 24 and an exhaust groove 27 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 and is connected to a ventilation pipe or the like (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 is exhausted to the outside. At the same time, the fresh air is sucked into the air supply groove 26 from the air supply unit. The air in the ventilation layer 24 is constantly circulated without being retained, thereby forming a heat insulating layer in the refrigeration section 21 to prevent the frost heave phenomenon of the ground.
[0007]
However, as in this example, providing a floor plate that also serves as the foundation to constitute the lower part of the skeleton, laying a deck plate on the entire surface under this floor plate, and separately laying heat insulating material requires equipment costs and construction costs. In other words, it was a factor that increased the overall construction cost of the freezing and refrigerated warehouse.
[0008]
[Problems to be solved by the invention]
The present invention has been made in view of the above circumstances, and provides a refrigeration / refrigeration that prevents the frost heave phenomenon of the ground by forming an efficient heat insulating layer while simplifying the structure of the lower frame and the formation of a ventilation layer. Provides a warehouse.
[0009]
[Means for Solving the Problems]
The refrigerated / refrigerated warehouse according to the present invention is basically a refrigerated / refrigerated warehouse which is provided with a ventilation layer under the lower structure of the frame to prevent the frost heave phenomenon of the ground by circulating outside air, and is mounted on the foundation and the foundation.

Specifically, the heat-insulating ventilation member is formed by laminating a ventilation layer and a heat insulating material. A floor plate in which a ventilation layer formed on the upper side of the heat insulating material is constituted by a deck plate and a support core of the deck plate disposed in the heat insulating material, or a gas permeable layer formed on the lower side of the heat insulating material is disposed in the heat insulating material. And a support core of
[0010]
Accordingly, the refrigeration / refrigeration warehouse according to the present invention eliminates the labor for installation for separately installing the deck plate and the heat insulating material, and simplifies the structure of the lower part of the frame and the formation of the ventilation layer while efficiently forming the heat insulating layer. By preventing the frost heave phenomenon of the ground by forming, the construction and maintenance cost of the freezing / refrigeration warehouse are reduced.
[0011]
BEST MODE FOR CARRYING OUT THE INVENTION
The refrigerated / refrigerated warehouse according to the present invention is basically composed of a foundation and a floor plate placed and supported on the foundation, and a heat insulating ventilation member arranged between the floor plate and the ground, specifically, The heat-insulating ventilation member is formed by laminating a ventilation layer and a heat-insulating material, and the ventilation layer formed on the upper side of the heat-insulating material is constituted by a deck plate and a support core of the deck plate disposed in the heat-insulating material, or It is characterized in that the ventilation layer formed on the lower side of the material is composed of the support core of the floor plate arranged in the heat insulating material, and the ventilation layer is formed under the lower structure of the building and the outside air is circulated to freeze the ground The phenomenon is prevented.
Hereinafter, embodiments of a freezing / refrigerating warehouse according to the present invention will be described in detail with reference to the drawings.
[0012]
FIG. 1 is a plan view (a) and a cross-sectional view (b) showing a freezing warehouse in the present embodiment, and shows an outline of the freezing warehouse.
[0013]
The freezer 1 in the present embodiment includes a freezing room 2 and a cargo handling room 3 as shown in FIG. 1 (a), and a foundation 7 including a foundation pile 6, a footing, a foundation beam, etc. The freezing room 2 and the floor plate 8 of the cargo handling room 3 which constitute the skeleton are integrally supported while being placed thereon.
[0014]
The outside air introduced by the air supply fan on the freezer compartment 2 flows through a later-described ventilation layer of a heat-insulating ventilation member 4 formed below the floor plate of the freezer 1, and the outside air is introduced into the freezer compartment 2 and the cargo handling chamber 3. Is taking away the cold. Next, the outside air cooled by the cold heat is discharged from the bottom of the freezer 1 to the outside of the freezer 1 by the exhaust fan on the handling room 3 side, and is formed below the freezing room 2 and the bottom of the handling room 3. The outside air cooled by cold heat is quickly removed without stagnation.
[0015]
In the case where the foundation beam divides the ventilation layer, a ventilation hole or the like penetrating therethrough is provided so that the ventilation layer is connected so as not to be divided.
[0016]
Thus, the heat insulating ventilation member 4 is disposed between the floor plate and the ground as shown in FIG. 1B, but is composed of a ventilation layer and a heat insulating material as described later. By circulating the outside air through the ventilation layer, as described above, the low-temperature outside air generated at the lower portion of the freezing chamber 2 and the lower part of the cargo handling chamber 3 is removed to prevent cold heat conduction by cold heat, and at the same time, heat conduction by the heat insulating material. By suppressing the cold heat from the freezing room 2 and the cargo handling room 3 from being transmitted to the ground by reducing the temperature, the freezing of the ground due to the cold heat of the freezing room 2 and the cargo handling room 3 is prevented.
[0017]
FIG. 2 is a cross-sectional view of a floor plate and a heat-insulating ventilation member of a freezing warehouse according to the present embodiment, which is indicated by arrows (2)-(2) in the cross-sectional view (b) of FIG.
[0018]
In the present embodiment, the floor plate 8 constituting the frame of the freezer 1 is formed on a crushed stone layer 10 laid on the ground 9 while being integrally supported on the foundation 7, A mat slab 11, a heat insulating material 12 such as styrofoam, and a floor concrete 13 are laminated.
[0019]
The heat-insulating ventilation member 4 disposed between the floor plate 8 and the crushed stone layer 10 includes a ventilation layer 4-1 and a heat insulating material 4-2.
[0020]
In this embodiment, the ventilation layer 4-1 is formed between the corrugated deck plate 4-3 and the heat insulating material 4-2 disposed on the upper surface of the heat insulating material 4-2. The upper surface functions as a formwork when the mat slab 11 of the floor plate 8 is cast, and the lower surface functions as a flow path 4-4 of the outside air that has been cooled. The deck plate 4-3 is installed on the crushed stone layer 10 by the support core 4-5. The support core 4-5 is formed in a pot shape by providing an opening on one side of the heat insulating material 4-2. Or is disposed in an insertion hole 4-6 formed through the heat insulating material 4-2 as shown in the drawing, and is installed in the heat insulating material 4-2 to support the deck plate 4-3. ing.
[0021]
For this reason, since the floor plate 8 configured as a lower frame of the freezing room 2 and the cargo handling room 3 is in a cooled state, the cold heat is conventionally transmitted from the crushed stone layer 10 to the ground 9 through the mat slab 11. In this embodiment, the frost heave phenomenon occurs on the ground 9. However, in the present embodiment, the floor plate 8 is integrally supported with the foundation 7, so that the deck plate 4-3 and the heat-insulating ventilation member are provided via the floor plate 8. 4 is sufficiently reduced from the building frame, and the area and contact pressure of the floor plate 8 in contact with the heat-insulating ventilation member 4 are reduced, and the floor plate 8 is transmitted from the floor plate 8 to the heat-insulating ventilation member 4. Cooling is further reduced.
[0022]
Further, in the present embodiment, since the ventilation layer 4-1 is formed by disposing the deck plate 4-3 between the mat slab 11 and the heat insulating material 4-2, the cooling and heating from the mat slab 11 is performed. Is removed by circulation of outside air or the like before being transmitted to the heat insulating material 4-2.
[0023]
Therefore, in the present embodiment, the load applied to the deck plate 4-3 between the mat slab 11 and the heat insulating material 4-2 is greatly reduced by integrally supporting the above-mentioned load on the frame by the foundation 7. Combined with the structure of reducing the airflow layer 4-1 and ensuring the ventilation layer 4-1, the degree of the cold heat conducted from the freezing room 2 and the cargo handling room 3 to the ground 9 through the floor plate 8 is drastically reduced. Thus, the state in which the frost heave phenomenon occurs on the ground 9 is largely prevented.
