Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a unit panel connecting structure which constitutes a face body which constitutes an assembly type heat insulating box (hereinafter referred to as a box). More specifically,
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a connecting structure for a box face body, which is configured by detachably connecting a plurality of unit panels in a plane, for example, a unit panel such as a ceiling, a side wall or a front wall.

[0002]

2. Description of the Related Art Conventionally, there has been known a box body constructed by a face body formed by connecting a plurality of unit panels. For example, as disclosed in Japanese Utility Model Application Laid-Open No. 51-50351, unevenness is formed on both side edges of a panel, and these unevennesses are fitted to each other to be assembled into a box.
The box body of this structure has the drawback that the joint portion is extremely weak against strength, particularly with respect to the force in the direction orthogonal to the panel surface, because the assembly and disassembly work of the box body only fit the unit panels directly to each other. . Bonding with an adhesive can be considered as a solution to this problem, but this causes a problem that disassembly becomes impossible.

Further, as shown in FIG. 14, in order to easily connect the edge portions of adjacent unit heat insulation panels, an angle member is fixed to the edge portions, and bolts are connected through the angle members. However, for example, there is one in which a side wall, a ceiling, or a front wall is configured to construct a heat insulating box. With this structure, the assembling or disassembling work is relatively easy, but the external appearance and the internal appearance are not good, and the angle member becomes a projection from the wall surface to reduce the internal volume. It was

For example, the assembling type heat-insulating box is not a box for carrying cargo, but a large box for accommodating telecommunications equipment or precision equipment when the equipment is installed in a remote place. When it is impossible to transport it, the face piece is disassembled into unit panels and transported, and then reassembled on site.

[0005]

SUMMARY OF THE INVENTION The present invention has been invented in view of the above-mentioned prior art. The box body can be easily assembled or disassembled, and the inner and outer walls of the box body are relatively attractive.
