DETAILED DESCRIPTION OF THE INVENTION [Industrial Application] The present invention relates to a heat insulating panel in which foamed heat insulating material is filled between inner and outer face plates arranged at a predetermined interval, and more specifically, the inner and outer face plates will be described. The present invention relates to a heat insulating panel in which a columnar member, a part of which is exposed, is arranged at the end of the heat insulating panel.

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 official gazette, for example, in a state in which a concave portion or a convex portion is formed at a connection end portion of a heat insulating panel having a size of one tatami mat with another panel, and the convex portion is combined with the concave portion, the rotary type Panels are connected and connected by a lock.

Problems to be Solved by the Invention When a heat-insulating panel is combined to form a box-like shape and a corner portion is formed as a box-like body, a convex portion or a concave portion is formed only at an end portion in the plate thickness direction of the panel. Since it is not possible to configure it by itself, one of the panels arranged at the corners,
The end face in the plate thickness direction is a flat face, and the concave groove is formed at the end of the inner surface member, so that the convex portion provided on the other end face of the panel can be combined. This makes it possible to form a heat-insulating box, but it is usual to provide a door inside the box for storing and removing stored items. When installing the door so that it is flush with the panel that makes up the frame, a frame is provided so as to surround the door, and this frame is installed, but a flat surface is required to install this frame (formation of this flat surface). The traditional columnar wood was used for). Especially when the door is attached to the corner of the box, the groove cannot be placed in the corner, so the door can be attached, but when installing the panels on the top and bottom of the door, For example, a special connecting member having an L-shaped cross section is required.
Therefore, there is a problem that the connecting member protrudes from the panel surface and only this connecting portion cannot be flattened. In addition, since the groove can not be arranged at the door mounting angle, a panel coupling device called a rotary lock cannot be arranged, and the panel mounting work becomes troublesome, and the panels are attached to each other. There was also a problem that it could not be firmly fixed.

Therefore, the present invention provides a heat insulating panel in which a columnar member having a concave groove and a flat surface is arranged with respect to the corner structure of the box body.
