Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] The present invention relates to a prefabricated heat-insulating box that forms a plurality of low-temperature chambers by connecting heat-insulating panels. More specifically, the thickness of each heat-insulating panel is different. The present invention relates to a prefabricated heat-insulating box having a connecting device that can be applied to different ones for each cold storage.

2. Description of the Related Art Since a temperature control zone is different between a case where a refrigerating room is manufactured using an insulating panel and a case where a freezing room is manufactured,
The need for heat insulation from the outside air is naturally different, and the required thickness of the heat insulation panel is different. When a heat insulating box having a plurality of chambers such as a freezing chamber and a refrigerating chamber is manufactured, a plurality of chambers formed of heat insulating panels having different thicknesses, for example, a T-shaped connecting portion at the boundary between the refrigerating chamber and the freezing chamber. Although they were connected using a heat insulation panel, the structure is complicated and it takes time to manufacture, and it is inconvenient for storage and transportation due to the weight.
A prefabricated refrigerator as disclosed in Japanese Patent No. 468 has been devised.

DISCLOSURE OF THE INVENTION Problems to be Solved by the Invention In the publications cited in the above-mentioned prior art, a chamber formed by connecting a plurality of thick heat insulation panels and a plurality of thin heat insulation panels are formed by connection. The chamber is a thick insulation panel, and the bent edge of the surface plate on the inner side is the same size as the bent edge of the thin insulation panel. None, the bent edge at the end of the surface plate on the outer surface side is extended by a difference in thickness with a thin heat insulating panel to form a connecting portion with a thin heat insulating panel, and this connecting portion has a thickness of Since the thin heat insulating panels are connected and provided adjacent to each other, the connecting structure of the panels having different thicknesses becomes simple and inexpensive.

However, when connecting the heat insulation panels that form the side surfaces of each room, there is no problem if the floor surface is made flush with concrete construction, but the same heat insulation panel that forms each room on the floor surface is used. If used, a rug with a different height is installed under the floor panel by the difference in the thickness of the heat insulation panel that forms adjacent chambers so that the lower ends of the side walls are at the same level, or the side panels of adjacent chambers are used together. It is necessary to arrange a coupling device so that it can be coupled even if there is a step at the lower end level, and it is necessary to install it at a position displaced by the difference in thickness, and the number of types of panels increases In addition to being complicated, there is a problem that assembly is restricted and lacks versatility.

Therefore, the present invention provides a prefabricated heat insulating box formed of a heat insulating panel having a versatile connecting device.

It is provided so as to form a ring. On this floor frame (42), a freezing heat insulation panel (2) is laid in the freezing compartment (5) and a refrigeration insulation panel (4) is laid in the refrigerating compartment (6) as floor panels. At this time, both rooms (5)
A difference in panel thickness, that is, a step difference of 50 mm occurs at a boundary portion of (6), that is, a connection portion between the refrigerating heat insulating panel (2) and the refrigerating heat insulating panel (4).

If the floor panels of the chambers to be operated are at the same height position, the first pin connects with the adjacent heat insulation panel, and if the upper surface of the floor panel of the adjacent chamber is at a different height position, it is adjacent to the second pin. It can be connected to the heat insulating panel, and the panel connection can be performed according to the height position of the floor panel.
