2. Description of the Related Art In order to construct a prefabricated refrigerator or freezer, a plurality of heat insulating panels are usually combined to form a box shape having a top wall, a side wall, and a bottom wall. In this combination, JP-A-62-91779 As disclosed in the publication, a concave portion and a convex portion are formed at an end portion of a heat insulation panel having a size of one tatami mat, and the convex portion is fitted into the concave portion, so that the concave portion and the convex portion are combined. Panels are joined together by a joining device called a rotary lock.

Problems to be Solved by the Invention In the above-mentioned conventional technology, if there is no convex portion due to the presence of a pillar or the like in the place where the prefabricated refrigerator or the freezer is arranged, the whole body may be a flat box body, which is another problem. Although there is no pillar, if there is a pillar or the like in the place (inside the building) where it is to be arranged, it is necessary to form an escape recess for escaping the convex portion. In forming this escape recess, prior to performing the assembly work, one of the panels forming a part of the ceiling wall is formed with a notch corresponding to the shape of the convex portion, Form a side wall panel and a bottom wall panel that match the size of the notch. However, when connecting the panels for forming these relief recesses, it is not possible to use the conventional recesses and protrusions and rotary locks, and the end face is made flat and another connection is made. Since it is necessary to connect the members by using members, there is a problem that the workability is poor and the panels cannot be connected in a strong state due to the notch work and the adoption of other connecting members.

Therefore, the present invention provides a heat insulating panel that has a notch corresponding to a recess for a column and allows a panel that is vertically connected to a panel surface to be connected and connected by a rotary lock.
