Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a heat insulation movable partition for a refrigerating / freezing room. More specifically, for example, a wall of a cold storage warehouse for refrigerating / freezing etc. The present invention relates to an improvement of a heat insulation movable partition for a refrigerating / freezing room, which is moved as needed to form a wall portion and is stored in a predetermined place when unnecessary to secure a space for another use.

[Prior Art] In general, various fruits and vegetables are harvested according to the season, and shipped to general retail stores and the like through agricultural cooperatives and fruit and vegetable markets, and then used. In this case, attention must be paid to the deterioration of freshness of fruits and vegetables in the fruit and vegetable market, and a cold storage warehouse or the like is required to prevent such quality deterioration. However, there are problems that fruits and vegetables have different targets and quantitative factors depending on the season, and it is difficult to install a cold storage warehouse or the like in terms of space. In addition, even in a store that handles a large amount of frozen products, it is necessary to thaw the food until it is displayed at the store.
It is necessary to temporarily keep cold, and in this case, it is desirable to be able to install a defroster or cold storage as needed. Therefore,
In order to solve these problems, a heat insulation panel that forms a simple warehouse with the wall of the room with a suspension movement insulation panel that can move along the rails installed on the ceiling of a building such as a cold warehouse Movable partitions are being considered. In this case, a conventional partition of this type is, as shown in FIG. 10 and FIG. 11, filled with a heat insulating core material b such as foamed polyurethane between a pair of surface plates a and a, and vertically and around the periphery thereof. A guide rail that is composed of a plurality of heat insulation panels formed by mounting left and right vertical frames c, d, and e, and these heat insulation panels f are installed along the ceiling h of the building through horizontal wheels g provided at the top of the heat insulation panels f. i
Slidably on the vertical frame e of each heat insulation panel f,
The structure has concavo-convex stripes j and k which are fitted to each other on the adjacent surface of e and are connected to each other to form a wall portion. Further, in order to insulate the gap between the upper end of the heat insulating panel f and the ceiling h, a gas-proof strip 1 is vertically provided from the upper end of the heat insulating panel f toward the lower surface of the guide rail i, and the lower surface of the guide rail i portion. Has a structure in which the air-proof strip 1 and a protective tongue m capable of polymerizing hang down (see Japanese Utility Model Laid-Open No. 59-163068).

[Problems to be Solved by the Invention] However, in the conventional partition of this type, the upper frame c of the heat insulating panel f has a support shaft n for mounting and supporting a horizontal wheel g.
The upper and lower frames c and d are formed separately, such that the lower frame d has a shape for mounting the lower airtight packing o and the lower frame d has a shape for supporting the lower airtight packing o. Also, the left and right vertical frames e
However, since the adjacent parts are a fitting method with uneven ridges j, k,
There was the inconvenience of having to prepare multiple types of vertical frames e, e ... Furthermore, since the airtightness between the heat insulating panel f and the ceiling h is due to the protective tongue piece m hanging from the ceiling h, there is a problem that a gap is formed on the left and right sides of the heat insulating panel f and the airtightness is impaired. It was
