DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a prefabricated cold storage constructed by connecting a plurality of heat insulating panels.
The present invention relates to a roof member mounting structure when installed outdoors.

[0002]

2. Description of the Related Art This type of prefabricated low-temperature refrigerator (refrigeration
For example, a refrigerator is disclosed in Japanese Utility Model Publication No. 5-14145 (F2).
As shown in 5D23 / 06), a heat insulating box was assembled by connecting a plurality of heat insulating panels to each other, and the heat insulating box was cooled to a predetermined temperature by a cooling device. In particular, in the above-mentioned publication, a freezing room is constituted by a thick insulating panel for freezing, and a cooling room is constituted by a thin insulating panel for cooling adjacent thereto.

[0003] Incidentally, such prefabricated low-temperature refrigerators are often installed outdoors because their overall dimensions are relatively large. Since it is necessary to deal with weather problems such as rain, wind, and solar radiation in the outdoor, a roof member is mounted on the prefabricated cold storage. Hereinafter, FIGS. 13 to 1
5, a conventional mounting structure for such a roof member will be described.

In each of the drawings, reference numeral 100 denotes an assembling-type heat-insulating box 102 constituted by connecting a plurality of heat-insulating panels 101.
, Which has an openable / closable heat-insulating door 103 on the front surface thereof for workers to enter and exit and to store stored articles. This heat insulation box 10
2 is installed via a skid 104 on an outdoor installation surface GL made of concrete, for example.

[0005] The heat-insulating box 10 of the prefabricated low-temperature storage 100.
For example, at the outer four corners of the support 2, for example, a support 106 having an L-shaped cross section
Are arranged along the outer surface of the heat insulating panel 101, and the lower leg portion 106A is fixed to the installation surface GL by an anchor bolt or the like (not shown). Each support 106 is a heat insulation panel 101A that forms a top wall of the heat insulation box 102 from the ground plane GL.
The heat insulating panel 10 is set as a dimension extending up.
Left and right columns 1 between the portions protruding above 1A
An angle member 107 is attached between 06 and 106 one by one in the front and rear directions, respectively.

[0006] Each of the angle members 107, 107 is located on the heat insulating panel 101A.
A roof member 108 made of a corrugated sheet is placed and fixed on 107. The roof member 108 is attached so as to be inclined so that the front side of the heat insulating door 103 is high and the rear part is low, and its front, rear, left and right sides protrude outward from the heat insulating box 102 to form an eave of a predetermined width. .

[0007]

Here, in a restaurant in the restaurant industry such as a family restaurant, a prefabricated low-temperature warehouse is constructed in contact with a building, and the building is directly placed in the prefabricated low-temperature warehouse without going out of the building. It is often possible to get in and out. However, the conventional roof member 108
In the mounting structure of (1), the heat insulating box 102 had to be separated from the building by the amount of the columns 106 and eaves.

Further, the heat insulating box 1 of the prefabricated low-temperature
The height of the support post 106 is also different in the conventional roof member mounting structure so that the height of the heat insulating box 102 can be changed. There is also a problem that the commonality of the parts is lost, the types of parts are increased, and the management cost is increased.

The present invention has been made to solve such a conventional technical problem, and does not use a support.
An object of the present invention is to provide a prefabricated low-temperature refrigerator to which a roof member can be firmly attached.

[0010]

SUMMARY OF THE INVENTION A prefabricated low-temperature refrigerator according to the present invention.

And a fixing plate provided on the refrigeration insulation panel constituting the top wall of the refrigeration room and projecting to the same height as the upper surface of the refrigeration insulation panel constituting the top wall of the freezing room; Angle material attached to the plate and provided from the upper side of the refrigeration insulation panel constituting the top wall of the refrigerator compartment to the top of the refrigeration insulation panel constituting the ceiling wall of the freezer compartment, and the refrigerator for constituting each ceiling wall Insulating bolts that penetrate the insulation panel and the freezing insulation panel, respectively, and fix the fixing plate and the angle material to each of the refrigeration insulation panel and the freezing insulation panel,
And a roof member attached to the angle member.

According to the prefabricated low-temperature refrigerator of the present invention, the angle member for attaching the roof member can be fixed to the heat-insulating box (heat-insulating panel) itself, so that the conventional supporting column is not required. Therefore, it is possible to work in contact with the building so that the building can be directly moved in and out of the prefabricated low-temperature storage, and it is not necessary to prepare columns having various dimensions, and the cost due to the use of common parts is eliminated. Can be reduced.

Further, since the angle member is fixed by bolts penetrating the heat-insulating box (heat-insulating panel), the mounting strength against wind pressure is sufficiently secured. Further, since the bolt is heat-insulating, it does not adversely affect the cooling of the inside, and also prevents the formation of dew or frost around the bolt due to the cooling from the inside.

In particular, a freezer compartment and a refrigerator compartment are constructed adjacent to each other.
When the height of the thick refrigeration insulation panel constituting the top wall of the freezer compartment and the thickness of the thin refrigeration insulation panel constituting the top wall of the refrigerator compartment are different, the angle material is passed over them. Can be installed stably.

Water surface door 71 and apron surface door 72 with an interval from the side
Attach each. The lower edges of the water surface door 71 and the apron surface door 72 have a wavy shape that is symmetrical to the top surface shape of the roof material 61, whereby rain or the like flows backward from the roof material 61 upper surface to the wall BW side. To prevent A draining panel 73 is attached to the upper surface of the apron face door 72 and reaches the outer surface of the wall BW while ascending toward the front, and prevents invasion of wind and rain from gaps between the wall BW and the heat insulating panels 3B, 4B.

On the other hand, around the roof member 61 other than the wall BW side, a nose cover panel 81 is attached by an attachment plate 82 and a tightening bolt 83 as shown in FIGS. The nose cover panel 81 improves the appearance by concealing the upper ends of the loop material 61 and the heat insulating panels 3 and 4 from the outside.

[0031]

As described above in detail, according to the present invention, the angle member for attaching the roof member can be fixed to the heat-insulating box (heat-insulating panel) itself. Therefore, it is possible to construct the prefabricated low-temperature warehouse in contact with the building and to make it possible to directly enter and exit the prefabricated low-temperature warehouse from inside the building, and it is not necessary to prepare columns having various dimensions, so that parts are not required. The cost can be reduced by the common use of the above.

Further, since the angle member is fixed by bolts penetrating the heat insulating box (heat insulating panel), sufficient mounting strength against wind pressure is ensured. Further, since the bolt is heat-insulating, it does not adversely affect the cooling of the inside, and also prevents the formation of dew or frost around the bolt due to the cooling from the inside.

In particular, a freezer compartment and a refrigerator compartment are constructed adjacent to each other.
When the height of the thick refrigeration insulation panel constituting the top wall of the freezer compartment and the thickness of the thin refrigeration insulation panel constituting the top wall of the refrigerator compartment are different, the angle material is passed over them. It will be able to be attached stably.
