Description

Construction method of low temperature refrigerated warehouse or frozen warehouse {CONSTRUCTION METHOD OF COLD STORAGE WAREHOUSE}

The present invention relates to a warehouse construction method, and more particularly, to a construction method of the freezer or low-temperature refrigerated warehouse that can be easily blocked and completely block the cold air.

Typically, walls and ceilings and floors of freezing warehouses or cold storage warehouses as independent structures are important structural parts to keep the temperature and humidity of the room constant by blocking hot air in the outside air, especially in summer. In particular, the ceiling is the structure that has the most influence on the quality and performance of the refrigerated warehouse because it is the place receiving the most direct sunlight.

On the other hand, the above-mentioned refrigeration and freezing warehouses are constructed by adhering insulation or bonding sandwich panels filled with insulation in order to maintain a constant indoor temperature from external temperature changes. Such construction methods are as follows. There are many problems.

Firstly, because Schiropol or iso-pink is constructed by attaching a plate to a wall, ceiling, or floor with a thickness of 600 mm, the space inside the warehouse is narrowed, and the seam is not only insulated, but also insulated.

Secondly, the conventional construction method has a disadvantage in that construction is difficult due to difficult construction at corners, around heat radiating doors, ceilings, pipe penetrations, and vertical / horizontal joints, and also requires manual construction.

Third, in the related art, since the bond is melted and adhered, considerable care is required, and in particular, it is not only harmful to the human body but also may cause a fire.

Fourth, the cold loss increases due to the peeling phenomenon due to the weakening of the adhesive force between the layers or layers of the plate as the time passes, and the increase of the management cost and the management cost according to the passage of time as the cold loss increases. There is also a problem that is increased.

Fifth, conventional construction surface is in the form of particles, so easy to invade the rat, the heat dissipation thickness is thick, there is a disadvantage that can long-term habitat of the rat.

Sixth, because the conventional anchor bolt is made of iron, there is a problem that the loss of cold air is not able to completely block the cold air in the warehouse.

Accordingly, an object of the present invention for solving the above problems is to provide a method for constructing a low-temperature refrigerated warehouse or a freezer warehouse with excellent stability and durability and simple construction.

Another object of the present invention is to provide a method for constructing a low temperature refrigerated warehouse or a freezer warehouse that can increase the internal space of a warehouse.

Still another object of the present invention is to provide a method for constructing a cold storage warehouse or a cold storage warehouse which can completely block cold air.

Still another object of the present invention is to provide a method for constructing a cold storage warehouse or a freezer warehouse which can be installed without using an adhesive.

The present invention according to the first aspect for achieving the above object is to form a urethane-based moisture-proof layer for waterproof and moisture-proof in the interior ceiling of the warehouse, and then to form a foam layer of hard polyurethane foam on the surface of the moisture-proof layer Implementing the construction method of a low-temperature cold storage warehouse or freezing warehouse consisting of a process of finishing the ceiling by the acrylic finish on the surface of the foam layer.

To propose a construction method that can prevent the leakage of water.

According to an embodiment of the present invention, the construction method of the low temperature refrigerated warehouse or the frozen warehouse proposed above is as shown in FIG. 1. Referring to FIG. 1, the construction method to be implemented in the present invention is divided into ceilings, floors, and walls of a warehouse, and each of them is constructed. The terms to be used in the present invention are summarized below before explaining the construction methods.

Moisture-proof layer refers to the urethane-based moisture-proof layer (102,116,118) formed by coating a urethane-based material on the ceiling or floor or wall of the warehouse, preferably for the waterproof and moisture-proof treatment, the thickness is about 1mm. The foam layer is formed by spray foaming the rigid polyurethane foam (104,114,134,138) by spraying on the surface of the urethane-based moisture-proof layer, the thickness is about 200mm. In this case, in detail, about # 15 to # 30 mesh is inserted into the rigid polyurethane foams 104 and 134. The base layer is formed by coating acrylic 108 with a thickness of 0.5 mm on the surface of the above-mentioned rigid polyurethane foam (104b).

{Example 4}

When describing a method for constructing a pillar installed in a cold storage warehouse or a cold storage warehouse, first, as shown in Figure 4, while maintaining a predetermined interval along the outer circumferential surface of the pillar concrete (100d) iron plate 140 in the form of a square box Then, the angle 142 was installed at each corner of the iron plate 140.

Subsequently, the inside of the iron plate 140, preferably by spray foaming the rigid polyurethane foam 144 in the space portion between the inside of the iron plate 140 and the column concrete (100d) completely filled to prevent airtight warehouse The pillar of was constructed.

As described above, the construction method of the low-temperature refrigerated warehouse or freezer warehouse according to the embodiment of the present invention achieves many effects as follows.

First, the present invention by spraying and foaming the urethane foam is only 300mm of the conventional 1/2 thickness, so that the space inside the warehouse is very wide, there is an advantage that can shorten the construction period and lower the construction cost.

Secondly, the present invention can be easily and completely installed in any shape by spraying or injecting with mechanical equipment, and also has the advantage that it can be completely adhered to any construction surface by self-adhesive force.

Thirdly, the present invention has almost no loss over a long period of time because the entire heat dissipating surface has no joints or peeling phenomenon, and there is almost no cold loss, so the maintenance cost is low and the change in cost is constant. Because it is difficult to invade the rat is composed of a synergistic effect that can not be inhabited.
