Therefore, the embodiments described in the present specification and the configurations shown in the drawings are merely the most preferred embodiments of the present invention and are not intended to represent all of the technical ideas of the present invention. Therefore, various equivalents And variations are possible.

Before describing the present invention with reference to the accompanying drawings, it should be noted that the present invention is not described or specifically described with respect to a known configuration that can be easily added by a person skilled in the art, Let the sound be revealed.

The present invention relates to an environmentally friendly warehouse using urethane panels.

Specifically, polyisocyanurate foam (PIR), which is made of urethane and has excellent thermal insulation effect, is used as an internal thermal insulation material, and exhibits an excellent thermal insulation effect due to its low thermal conductivity. The natural closed cell structure of the thermal insulation material penetrates or adsorbs water or moisture Which is resistant to contamination and has enhanced resistance at high temperatures to exhibit excellent flame retardancy and heat resistance, and which is improved in low conductivity and assembled using a urethane panel having superior physical properties.

Prior to the explanation according to the present invention, referring to the urethane panel, [Table 1] can be referred to.

As shown in Table 1, a urethane panel is constituted by sequentially placing a PVC layer and a zinc steel sheet between two coating layers, and placing a urethane foam between two galvanized steel sheets positioned and assembled.

The end joints for assembling between the urethane panels may be as shown in Table 2, but it is possible to adopt all the bonding methods that can be implemented by the ordinary skilled in the art based on the technical level at the time of application of the present invention.

An example of assembling into a pantry using such a urethane panel is shown in Fig. 1 of the accompanying drawings.

1 shows an assembled structure of an environmentally friendly storage using a urethane panel according to the present invention.

BRIEF DESCRIPTION OF THE DRAWINGS Fig.

A bottom panel 10 manufactured by assembling a urethane panel to the foundation assembly after installing the base assembly (see the dotted line of the bottom panel in FIG. 1)

A plurality of wall panels 20 connected to the bottom panel 10 to form side walls,

And a ceiling panel (30) positioned in association with the wall panel (20) on the upper side of the structure in which the wall panel (20) is assembled,

In at least one of the plurality of wall panels 20,

An opening for installing the door is formed, and the door is coupled to the opening, thereby completing the storage space.

At this time, in the plurality of wall panels 20, it is possible to refer to [Table 2] that adjoining ones are coupled to each other.

Also, a conventional coupling method can be used for the assembly of the wall panel 20 and the bottom panel 10 or the ceiling panel 30, but it may be combined as follows according to design conditions.

Referring to Table 3, the bottom panel 10 is formed with a coupling groove 11 which is concavely downwardly formed on one side of the upper surface to which the wall panel 20 is coupled.

At this time, the engaging groove 11 is formed such that the size of the entrance portion is smaller than the size of the inner groove portion of the engaging groove 11.

An engaging protrusion 21 protruding downward is formed at one side of the lower surface of the wall panel 20 so that the engaging protrusion 21 is inserted into the engaging groove 11 of the bottom panel 10,

A packing 20a is formed on the lower surface of the wall panel 20 where the coupling protrusions 21 are not formed.

In addition, the engaging projections 21 are formed,

A hinge 22 protruding perpendicularly to the side surface of the side surface, the hinge 22 protruding symmetrically in two directions on the two side surfaces of the engaging projection 21,

A pin 23 inserted into the hinge 22 and forming a rotation axis,

And a rotation fixing part (24) coupled to two side surfaces of the coupling protrusion (21) and coupled to the pin (23) to rotate about the pin (23)

The rotation fixing part (24)

(a) a through hole (24a) having a concave groove formed on one surface thereof so as to allow the hinge (22) to be inserted therein and penetrating from the end to the end in the vertical direction with respect to the groove, And an auxiliary packing (24b) formed on one side of the rotation fixing part (24) so as to protrude beyond the length of the coupling projection (21)

(b) The shape of the rotation fixing part 24 is formed in an 'a' shape so that both ends are curved for easy rotation.

At this time, a concave groove 21a for inserting a part of the rotation fixing part 24 may be formed at one side of the coupling protrusion 21.

In Table 3, it can be seen that the strength of one side of the engaging projection 21 can be reduced by the constitution of the concave groove 21a of the engaging projection 21. [Table 3] shows the sectional shape, Since the concave groove 21a is formed only in a part of the engaging projection 21, the strength of the engaging projection 21 will not be lowered.

The through hole 24a is formed in the shape of an ellipse extending in an elliptical shape having a smaller diameter upward with respect to the circular hole, and the area having a small diameter is equal to or slightly larger than the diameter of the pin 23 And the region having a large diameter is configured to have a size at least two times larger than the diameter of the pin 23. [

The technical significance of the shape of the through hole 24a is set forth in [Table 4] and [Table 5] while describing the operation relationship.

As the coupling protrusion 21 is inserted into the coupling groove 11 as shown in Table 4, the auxiliary coupling 24b contacts the inner bottom surface of the coupling groove 11, and the rotation fixing portion 24 is slightly raised .

At this time, the pin 23 located in the small diameter region of the through hole 24a is also positioned in the large diameter region of the through hole 24a as the rotation fixing portion 24 rises.

As a result, the pin 23 is easily rotated on the through hole 24a, and the rotation fixing portion 24 is rotated as shown in Table 5 by the curved surface of the rotation fixing portion 24. At this time, The total height h1 from the end of the rotation fixing portion 24 to the auxiliary packing 24b is equal to or slightly larger than the width w1 from the end of the coupling projection 21 to the inner wall of the coupling groove 11 The auxiliary packing 24b is moved from the side wall of the engaging projection 21 to the side wall of the engaging projection 21 because the rotation fixing portion 24 is rotated as shown in Table 5 and at the same time the pin 23 can move further on the through hole 24a It has a hermetic effect to block the flow of the air flowing in the direction of the arrow in Table 5 together with the stable fixing by the depression, so that the temperature inside the storage is maintained and the cold or warm air is prevented from flowing out.

At this time, the packing 20a formed on the wall panel 20 functions as a primary hermetic function and the secondary packing 24b functions as a secondary hermetic function.

It should be understood that the foregoing description of the present invention has been presented for illustrative purposes only and is not to be construed as limiting the scope of the present invention as defined by the appended claims.
