As shown in FIG. 1, the freezing warehouse 10 is a bottom panel part 2 that forms a floor by assembling respective insulating panels, a ceiling panel part 4 that forms a ceiling, and a wall panel part that forms a wall. (6) and a door device 10 installed at the entrance and exit of the wall panel part 6.

Referring to FIGS. 1 and 2, the door frame 10 for a freezing warehouse according to the present invention is a door frame mounted at an entrance 8 formed in a wall panel part 6 of a freezing warehouse (or a cold storage) 1. And a door 200 rotatably coupled to the door frame 100 to open and close the doorway 8. For reference, the door 200 is connected to the hinge 600 on one side of the door frame 100 and the door lock 700 is installed on the other side of the door 200 and the door frame 100.

3 is a cross-sectional view taken along the line b-b of FIG. 2. 4 is an enlarged cross-sectional perspective view of the main portion of the door apparatus. 5 is an enlarged cross-sectional view of a main part showing a state in which a door is opened.

3 to 5, the door frame 100 has an inner surface 102 to which the door 200 is contacted, and a front surface which is bent from the inner surface 102 to be in contact with the outdoors and the interior of the freezing warehouse 1, respectively. Insulation material filled in the interior space created by the 104 and rear surface 106 and the outer surface 108 and the outer surface 108 and the outer surface 108 opposite the inner surface 102 and the combination thereof 190. Here, the heat insulating material 190 may use a foamed urethane.

The inner side surface 102 of the door frame 100 includes a first contact portion 110a and a second contact portion 110b. The first contact portion 110a is bent outward to the corner portion in the direction of the front surface 104. The first packing 210 of the door 200 is interviewed with the first contact part 110a. The second contact portion 110b is bent inward to the corner portion in the direction of the rear surface 106. The second packing 220 of the door is interviewed with the second contact part 110b. As such, the inner surface 102 of the door frame 100 has a plurality of contact portions 110a and 110b which are formed stepped stepwise.

The door device 10 of the present invention has a second packing in which the first packing 210 and the second contact part 110b interview the first contact part 110a in the gap between the door 200 and the door frame 100. Insulated air layer A is provided between 220. This adiabatic air layer (A) can minimize the external air flowing from the outside (outside) is in direct contact with the cold indoor air of the freezer (1).

It is preferable. The hot wire cover 116 has a cross-sectional shape viewed from the plane in the form of a memory. In this structure, since the heating wire 112 is installed outside the inner surface, the heat of the heating wire 112 may be minimized from being transferred to the inside of the freezing warehouse along the inner surface. In addition, heat of the heating wire 112 may be transferred to the heating wire cover 116 to prevent the first packing (or the second packing) from freezing. In addition, the hot wire repair operation is easy to maintain because the hot wire 112 is exposed to the outside only by removing the hot wire cover 116.

Meanwhile, the outer surface 108 of the door frame 100 includes clip portions 109 having a '형상' shape in which both ends of the chassis member 180 are fitted and fixed. The chassis member 180 extends from a central portion 182 and a central portion 182 having a concave surface 183 and a convex surface 184 for male and female coupling, and an extension portion fitted into the clip portion 109, respectively. (186). The chassis member 180 is coupled to the panel chassis member 30 corresponding to the edge of the heat insulation panel 20 forming the wall panel part 6 of the freezing warehouse. The chassis member 180 is formed in the same shape as the heat insulating body 31 of the chassis member 30 for the panel, and is assembled in a male and female coupling manner. Although not shown, they are mutually coupled by separate fastening members.

As described above, the door device 10 of the present invention is provided with a chassis member 180 for fastening (assembly) with the panel chassis member 30 of the thermal insulation panel 20 forming a wall on the outer side surface 108. Excellent assembly with the wall panel part 6 corresponding thereto, it is possible to minimize the leakage of cold air that may occur in the coupling portion of the heat insulation panel 20 and the door frame 100 of the wall panel part 6.

Here, the heat insulating panel 20 forming a wall includes two front plates 21 and 22 made of a metal plate, a panel chassis member 30 surrounding the side surface, and a heat insulating material 40 filled in an inner space thereof. It includes. Each of the panel chassis members 30 are detachably coupled to the rectangular heat insulation body 31 and one end of the heat insulation body 31, and a clip into which a bent piece formed at an edge of the first front plate 21 is fitted. A first molding 32 having a portion 33 and a clip portion 35 to be detachably coupled to the other end of the heat insulating body 31, the bending piece formed on the edge of the second front plate 22 is fitted Second molding 34 is included. The heat insulation body 31 and the first and second moldings 32 and 34 are made of materials having different thermal conductivity. Preferably, the heat insulation body 31 is made of a high-strength and excellent heat-resisting polystyrene impact resistance, the first and second moldings (32, 34) is made of a PVC-based material.

The door 200 has a door body 202 filled with a heat insulator 201 therein, a frame rim 204 installed at an edge of the door body 202, and an edge 204. The first packing 210 and the second packing 220 is included. The edge portion 204 has a fitting piece 206 in which both first packing 210 and second packing 220 are fitted. The first packing 210 and the second packing 220 is detachably coupled to the fitting piece 206 of the edge portion 204 to facilitate the replacement of the packing.

6 is an enlarged cross-sectional view of the main portion showing the state in which the door is closed.

As shown in FIG. 6, when the door 200 is closed, the first packing 210 and the second packing 220 of the door are connected to the first contact part 110a and the second contact part 110b of the door frame 100. While being in close contact with each other, an insulating air layer A is formed between the first packing 210 and the second packing 220. This adiabatic air layer (A) acts as a buffer (buffer) space that prevents the outside air introduced from the outside (outside) is in direct contact with the cold indoor air of the freezer 1. Of course, even if the outside air penetrates through the gap between the door 200 and the door frame 100 and water vapor is condensed on the first packing 210 and the second packing 220, the first contact part 110a and the second contact part. It is possible to prevent the first packing 210 and the second packing 220 from freezing by the heating wire 112 provided in the unit 110b.

In particular, since the door 200 is of a type embedded in the door frame 100, a safety accident that the worker hits the door 200 may be prevented.
