REMOVABLE MULTI-PANELED WALL CONSTRUCTION

A double-walled building panel is disclosed which is adapted to be marginally interconnected with one or more other such panels to form a rigid but readily removable wall construction. The panel comprises a pair of flat parallel wall members which are registered opposite one another with a clearance therebetween; and a framing structure of elongated framing members which are interposed in the clearance between the wall members, along the opposite edge portions of the panel. The framing members have similarly shaped bodies in transverse cross-sectional planes thereof, and each of the bodies has spaced, parallel, longitudinally extending, exteriorly oriented surfaces on opposite sides thereof, corresponding edges of which surfaces are disposed in a common longitudinal cross-sectional plane of the body. Each body also has complementary longitudinally extending tongue and groove means thereon, which are oppositely oriented with respect to the aforesaid longitudinal cross-sectional plane and interposed in the space extending between the surfaces. The groove means include a pair of grooves which are oppositely disposed to one another in the body, and transversely oriented to the surfaces. The tongue means include a pair of flexible prongs which project relatively outwardly from the body, and which are spaced apart from one another transversely of the surfaces. When two panels are interconnected with one another, the framing members along the opposite interconnecting edge portions thereof, are similarly oriented to one another in the same, and the prongs of one are interengaged with the grooves of the other, there being means on the bodies of the framing members operative to cause the prongs to flex relatively toward one another, as the tongue means of the one framing member are inserted and withdrawn with respect to the groove means of the other framing member.
