Description

[Detailed description of the invention] [Industrial field of application] This invention relates to a low-temperature refrigerator, such as a constant-temperature refrigerator or a freezer, in which the temperature inside the refrigerator is lower than the temperature outside the refrigerator.

[Conventional technology and its issues]

Conventionally, a polyester sheet, an asphalt sheet, a rubber asphalt-based spray material, or the like is generally used as a moisture-proof layer installed in a constant-temperature warehouse such as a constant-temperature warehouse or a freezer. There was no such moisture barrier that could stand on its own, so a moisture barrier material was pasted on the inside of a waterproof plywood or board base.
Cold air from inside the room may enter the insulation layer through the wall panels or their joints, causing dew condensation within the insulation layer, and the installation work of the insulation material and wall panels is complicated and difficult to install. . This phenomenon becomes noticeable even in low-temperature storage when the temperature drops to -20°C or lower, and if dew condensation occurs outside the moisture barrier layer, the durability of the moisture barrier layer and the building itself will be significantly reduced.

[Means to solve the problem]

The gist of this idea is that a metal plate moisture-proof layer, multiple layers of heat insulating material, and interior materials are arranged in this order on the inside of a building frame consisting of columns, beams, exterior walls, and roof, and the metal plates forming the moisture-proof layer are mutually interconnected. It is characterized by being sealed with a laminated adhesive, the top surface of the ceiling metal plate moisture barrier layer forming a sloped surface for water drainage, and a drainage space that communicates vertically between the outer wall and the outer surface of the wall metal plate moisture barrier layer. It's in a cold storage.

[Effect]

This low-temperature refrigerator uses a metal plate moisture-proof layer, and the metal plates are stacked on top of each other and sealed with adhesive, so it has superior moisture resistance compared to conventional moisture-proof layers, and can maintain airtightness at joint screw-fastened areas. The upper surface of the ceiling metal plate vapor barrier layer forms a water draft surface, and there is a drainage space that communicates vertically between the outer wall and the outer surface of the wall metal plate vapor barrier layer, so even if condensation water occurs, it will not flow through the drainage space. can be discharged outdoors. Since multiple layers of heat insulating material are placed inside the metal plate moisture barrier layer, cracks are less likely to occur during earthquakes, etc., and the heat insulating performance is maintained over a long period of time. Compared to conventional moisture-proof layers, metal moisture-proof layers are self-supporting, can form a moisture-proof layer in one layer, are easy to install, seal joints with adhesive, and do not require welding, making them even safer and easier to work with. improves.

〔Example〕

In FIG. 1, the framework of the low-temperature refrigerator is constructed by attaching corrugated color steel plates 3 for the outer wall and polyurethane-coated color folded plates 4 for the roof to the outside and top surfaces of steel columns 1 and steel beams 2. An angle member 5 and a rim 6 are arranged between the pillar 1 and the iron plate 3 to support the iron plate 3.

Inside the room at the upper and lower ends of the column 1, horizontal upper and lower supporters 7, 7 and a mullion 8 are arranged between them, and the moisture-proof steel plate 9-1 of the galvanized steel plate wall covers the indoor side. It is installed. In addition, as shown in FIG.
-2 is attached to the beam 2 with a downward slope facing the outdoor side via the hanging bolt 10, the field edge support 11, and the field edge 12 of C-shaped channel material, and its tip end reaches the indoor side of the column 1. It stretches and bends downward.

At the upper and lower ends of the moisture-proof steel plate 9-1 of the wall, adhesive tape 13 is inserted between the mullion supports 7, 7 as shown in FIG.
It is fastened and fixed with screws 14, and the upper end is bent and overlapped with the ceiling moisture-proof steel plate 9-2, with adhesive tape 13 inserted between them, and fastened and fixed with screws 14. In addition, the moisture-proof steel plates 9 of the ceiling and walls are joined to each other and to the roof edge, etc. by overlapping each other as shown in FIG. 13 is inserted and fastened and fixed with screws 14.

The mullion holder 7 at the upper end is an angle 15 attached to the pillar 1.
The mullion support 7 at the lower end is fixed by anchor bolts 16 buried in the concrete of the frame, and the drainage plate 17 facing outdoors and sloping downward is attached to the moisture-proof steel plate 9-1 above. Adhesive tape 1
3 is inserted and screws 14 are tightened. As shown in FIG. 1, a drainage space 18 that communicates vertically is formed between the moisture-proof steel plate 9-1 of the wall and the steel plate 3 of the outer wall at the tip edge of the moisture-proof steel plate 9-2 of the ceiling, and the lower end of the drainage space 18 is formed. is connected to the outside of the warehouse via a drainage gap 19 between the lower end of the iron plate 3 and the foundation concrete.

On the indoor side of the moisture-proof steel plates 9-1 and 9-2 of the walls and ceiling, a heat insulating material 20 made of multiple layers such as urethane foam is laminated, and the surface thereof is covered with a fireproof coating layer 21. It is covered with.

A heat insulating material 22 such as polystyrene foam is laid in the concrete floor of the low-temperature warehouse.

[Effect of idea]

This invention is as described above, and this low-temperature refrigerator has the following effects.

○B It is possible to prevent condensation within the insulation layer and ensure insulation performance.

○B Even if dew condenses on the outer surface of the moisture-proof layer of the metal plate, it can be discharged outside the refrigerator, so there is no deterioration in insulation performance. Durability can be improved.

○C The insulation material is less prone to cracking and can maintain long-term performance.

○D The workability of insulation construction can be improved.
