Regarding a hanging assembly type refrigerator.

(B) Prior Art Hereinafter, a conventional sectional refrigerator disclosed in Japanese Patent Application Laid-open No. 134862/1983 will be explained with reference to FIGS. 1 to 5.

Fig. 1 shows a prefabricated refrigerator constructed by connecting and connecting a plurality of heat insulating plates 2, 3, and 4 that form the bottom wall, side wall, and ceiling wall, and is equipped with a heat insulating door 5 that can be opened and closed on one side of the side wall. The inside of the refrigerator is equipped with a cooling device 6 that houses a cooler, a blower, and the like. As shown in FIGS. 2 and 3, each of the heat insulation plates 2, 3, and 4 is composed of two plates 7 and 8 and a foamed heat insulating material 9 filled between the plates, and are in contact with each other. Either a concave portion 10 or a convex portion 11 is formed on the connection surface. One coupling device 13 with a pin 12 is formed in the concave portion 10, and the other coupling device 15 with a hook 14 is provided in the convex portion 11. Both of the connecting devices form a pair and are buried in predetermined positions in the heat insulating material 9 with the openings facing outward. After being loosely engaged with the heat insulating plates 4, the hooks 14 pull the concave portions 10 to the convex portions 11, thereby connecting the two heat insulating plates 4,4. Reference numeral 16 denotes a beam provided to cover the upper part of the connection part of the short dimension connecting surface which is not supported by the insulation board 3 forming the side wall in the insulation board 4 forming the ceiling wall, and the beam is made of a light metal such as aluminum. molded with two parallel legs 1 over its length.
7 and 18, and a recess 19 between the legs, and a plurality of insertion holes 20 connecting the inside and outside of the recess. 21 has one end inserted and locked into the inside of the connecting device 13, and the other end is inserted into the beam 16.
It is a plate-shaped support that is fixed to the leg portion 18 of the heat insulating plate 4 and supports the connecting portion of the heat insulating plates 4, 4, and is bent to adapt to the shape of the concave portion 10 or the convex portion 11.
Further, as shown in FIG. 4, the insertion piece 21' inserted into the interior of the connecting device 13 is formed with a cut groove 21'' for maintaining engagement with the pin 12.2.
Reference numerals 2 and 23 denote a pair of fasteners consisting of bolts and nuts, which are inserted into the long hole 21 of the fitting part 21A of the plate-shaped support 21.
Insert the fixing tool 22 into the insertion hole 20 via A',
By tightening the fixing device 23, the heat insulating plates 4, 4...
The connecting portion is fixed to the beam 16.

In the method of assembling the conventional refrigerator 1 described above,
When the heat insulating plates 4, 4 are connected first, the beam 16
The fixing device 22 is blocked by the front leg portion 18 into the recess 19 of the
cannot be entered. Therefore, the insulation plates 4, 4
Before connecting the heat insulating board 4 and the beam 16, it is first necessary to fix the heat insulating board 4 and the beam 16 using the plate-shaped support 21 and the fixing devices 22, 23. This fixing work is done by inserting the fixing device 22 into the recess 19 of the beam 16 from below. The work becomes complicated because the beams 16 and the heat insulating plates 4 are not stable until the heat insulating plates 4, 4 are connected, and there is a risk that the beams 16 and the like may fall. Further, FIG. 5 shows a state in which the beam 16 is temporarily installed, with one end of the beam 16 resting on the heat insulating plate 4, and the other end resting on the auxiliary block 24 fitted to the upper end of the side plate 3. The beam 16 was supported at a proper position inside the warehouse by a support column 25.
Therefore, there is a risk that the beam 16 will come off from the auxiliary block 24, and the auxiliary block 24 and the support column 25 will get in the way of the work when connecting the heat insulating plates 4, 4... 25 has to be moved as shown by the chain line every time the heat insulating plates 4, 4, . . . are connected, resulting in a disadvantage that workability is reduced.
