Panel construction
Abstract
Abstract A GENERALLY T-SHAPED PREFABRICATED WALL PANEL. THE CROSSBAR OF THE T HAS AN OFFSET PORTION AT ONE END AND A PAIR OF LIMBS AT THE OTHER END WHICH DEFINE A CONTINUOUS GROOVE. AN OUTWARDLY PROJECTING THIRD LIMB IS CONNECTED TO ONE LIMB WHICH DEFINES A PART OF THE GROOVE. THE END OF THE UPSTANDING MEMBER OF THE T OPPOSITE THE CROSSBAR HAS A PAIR OF BRANCHES WHICH DEFINES A CONTINUOUS GROOVE. TWO LIKE WALL PANELS ARE JOINED BY INSERTING THE OFFSET PORTION OF ONE PANEL INTO THE GROOVE DEFINED BY THE PAIR OF LIMBS OF THE OTHER PANEL. WHEN THE PANELS ARE SO JOINED, THEIR CROSSBARS ARE IN THE SAME PLANE. A THIRD LIKE PANEL IS CONNECTED TO THE FIRST TWO PANELS BY CONTACTING THE THIRD LIMB OF THE THIRD PANEL TO THE GROOVE DEFINED BY THE PAIR OF BRANCHES OF ANY OF ONE OF THE OTHER TWO PANELS, THEN SCREWING OR SPOT WELDING THE CONTACTING SURFACES TOGETHER. WHEN THE THIRD PANEL IS SO CONNECTED, ITS CROSSBAR DEFINES A WALL PARALLEL TO AND SPACED APART FROM THE WALL DEFINED BY THE CROSSBARS OF THE FIRST TWO PANELS.
