Description

The present invention relates to a simple box-type room.

A prefabricated box-type simple room made of corrugated cardboard, foam board, or the like is known. This type of box-shaped simple room is used as a bed (bed) in, for example, an evacuation shelter in the event of a disaster. When a user enters the box-shaped simple room, the user is surrounded by walls, so it is necessary to block the line of sight from the outside (that is, to secure the user's privacy) and Light (illumination), noise, etc. can be blocked.

For example, Patent Literature 1 discloses a box-type bedding in which corrugated cardboard is bonded to an expanded board made of foamed polystyrene or the like and used as wall materials (top plate, side plate, etc.). In Patent Literature 1, a plate-like corrugated board material that is one size larger than the foam board material is attached with an adhesive and used as a wall material (a top plate, etc.). That is, as the wall material, a corrugated cardboard material is used so as to cover the entire surface of the foam board material. The wall materials are connected to each other by inserting the ends of the corrugated board protruding outside the foamed plate material into the grooves provided in the foamed plate material of the other wall material.

Registered Utility Model No. 3219523

In a conventional box-type bedding, when stored for a long period of time in a state before assembly, the members constituting the wall material shrink, and the wall material sometimes warps. The corrugated board that is attached to the foam board material that makes up the wall material shrinks more than the foam board material, so it warps due to the difference in shrinkage between the foam board material and the corrugated board material. Become. If the wall materials are warped, it is difficult to connect the wall materials during assembly.
