Abstract:
A prefabricated building panel comprising,first and second generally planar side members each having first and second longitudinally extending parallel edges, said first side member being spaced from and co-planar with said second side member,a first edge surface spanning between said first edge of said first and second side members substantially along their longitudinal length, said first edge surface including a pair of longitudinally extending spaced apart projecting members and a pair of shoulder members, said projecting members, each being symmetrically disposed about a mid-plane of the building panel and defining a longitudinally extending slot therebetween,a first one of said shoulder members joining said first side member and a first one of said projecting members,the second other one of said shoulder members joining said second side member and the second other one of said projecting members,a second edge surface spanning between said second edges of said first and second members substantially along their longitudinal length, said second edge surface configured for mated engagement with a first edge member of an adjacent panel and including,first and second spaced apart channels, each having a complementary size and shape to said first and second projection members, respectively,a tongue separating said first channel from said second channel and being centered on said panel mid-plane, said tongue sized for complementary fitted placement to completely fill in said slot and extending substantially the longitudinal length of the second edge member,a first end face extending from said first side member to said first channel, said first end face having a complementary size to said first shoulder member,a second end face extending from said second side member to said second channel, said second end face having a complementary size to said second shoulder member,a rigid insulating core material interposed between said first and second side members,wherein when said second edge surface is positioned in mated engagement with a first edge surface of an adjacent panel, said first and second projection members located in said respective first and second channels with said tongue disposed in said slot and said first end face abutting said first shoulder and said second end face abutting said second shoulder.
