Description

[Detailed description of the invention] This invention relates to a heat insulation structure for cold storage warehouses, etc., and makes interior construction for heat insulation extremely easy to carry out.

In order to prevent foods from spoiling and to prevent the proliferation of bacteria, the inside of frozen warehouses should be kept as cold as possible, for example -40°C.
It is required to maintain a temperature between 'C and -50°C.

In order to maintain such low temperatures, insulation panels made of porous plastic with an extremely small coefficient of thermal conductivity and low moisture absorption are pasted in multiple layers on the side walls, ceiling, and floor surfaces of cold storage warehouses. This is commonly done.

In this conventional construction, asphalt, pitch, etc. were used and pasted one layer at a time, but because of the odor and danger of heated asphalt and pitch, the construction period was longer and the costs for interior construction were higher. .

Therefore, in this invention, we tried to provide a heat insulating structure that can be constructed to eliminate the above-mentioned conventional drawbacks.The structure consists of a plate-shaped body made of porous plastic with a recess formed on one side, and a concave part formed on the other side. It is characterized in that a convex portion that can fit into the above-mentioned concave portion is formed on the surface, and the plate-like bodies are stacked in a staggered manner so that the concave and convex portions are joined to each other.

Next, embodiments of this invention will be described below with reference to the drawings.

1 is a plate-shaped body made of porous plastic, such as porous polystyrene resin, hard vinyl chloride resin, hard polyurethane resin, etc.; 2 is a recess formed on one side 1a of the plate-shaped body 1;
Reference numeral 3 denotes a convex portion formed on the other surface 1b of the plate-shaped body 1, and this convex portion 3 can be fitted into the concave portion 2 described above.

Reference numeral 4 indicates a component board of a warehouse or the like in which a heat insulating material is installed.

The above-mentioned recesses 2 and protrusions 3 are formed at positions where the plate-like body 1 can be stacked and joined to other plate-like bodies 1 having the same structure in a staggered manner with alternate positions. For example, it is most preferable that the concave portions 2 and the convex portions 3 are formed at equal intervals in the vertical and horizontal directions (see FIGS. 1 to 5). This is carried out by forming recesses 2 and protrusions 3 to enable staggered joining (see FIGS. 6 to 8).

Furthermore, if the thickness of the plate-shaped body 1 is made equal to the pitch of the uneven parts 2 and 3, and the peripheral part is made flat by eliminating the protruding parts 3, it is possible to construct the combination of the corner parts without any processing effort (see 4. (see figure).

Furthermore, a simple geometric pattern is suitable for the shapes of the above-mentioned recesses 2 and protrusions 3, and it is possible to fit them even if the recesses 2 and protrusions 3 do not necessarily have the same shape as shown in Figures 1 to 4. For example, shapes such as those shown in FIGS. 5 to 8 can be implemented.

In practice, each part of FIGS. 9 and 10 can be implemented with the following example dimensions.

Example 1 [Dragon] Example 2 [Throat] A = 50.5 A = 50.5A'=
25.25 A'=25.25B=909
B=909C=606
C=606 D=50 D=50E=10
E=10 F=30φ F=25 angle Note that A' can be set to 1/2ffμ of A as described above, which is 172 pitches of uneven parts, or it can be set to N+112 pitches (N is a positive integer).

It consists of the above configuration.

This idea is used for the heat-insulating interior of side walls, ceilings, floors, etc. of refrigerated warehouses that need to be maintained at a constant temperature and low temperature. 1 are fitted with the concave part 2 on one side and the convex part 3 on the other side, and are sequentially stacked and joined in a staggered manner to easily form a multilayer heat-insulating layer (see Figures 3 and 4). ).

In addition, in construction, we do not use a heat insulating material with both uneven parts for the outermost and innermost layers, but use a plate-like material with only concave parts and only convex parts, so that the outermost and innermost layers of the multilayer have uneven parts. You can also prevent it from appearing.

In addition, according to this invention, the recesses 2 and the protrusions 3 to be fitted are formed so that they can be joined in a staggered manner, so that after construction by fitting as an interior material for a frozen warehouse, etc., the board In addition to being convenient for preventing leakage of cold air since the joints between the multiple layers made up of the shaped body 1 do not continue in a straight line, it is also easy to use when cutting and joining only the necessary amount of the plate-shaped body 1 at a corner of the above-mentioned warehouse, etc. Become something.

As described above, since the insulation material for interior construction of cold storage warehouses etc. can be joined using the concave and convex parts of the plate-shaped body, heated asphalt, pitch, etc. can be interposed between the insulation materials as in the past. There is no need to join them together, and there is no odor or work hazard, creating a good environment for construction work.
This is extremely practical in terms of shortening construction time, shortening the construction period, and reducing construction costs.
