Sheet metal modular wall units
Abstract
Abstract THE INVENTION PROVIDES A MODULAR STRUCTURAL MEMBER FORMED FROM A RECTANGULAR SHEET METAL BLANK BENT TO DEFINE A MEDIAL PANEL SECTION FLANKED BY OPPOSITE REARWARDLY EXTENDING MARGINAL SECTIONS. ONE MARGINAL SECTION COMPRISES A TONGUE AND, SPACED REARWARDLY THEREOF, A LATERALLY OUTWARDLY PROJECTING REARWARDLY FACING FLANGE THAT IS OFFSET LATERALLY INWARD A SUBSTANTIAL DISTANCE FROM THE TONGUE. THE OTHER MARGINAL SECTION COMPRISES A GROOVE PORTION LATERALLY OPPOSITE THE TONGUE AND ANOTHER FLANGE, LATERALLY OPPOSITE THE FIRST AND PROJECTING LATERALLY OUTWARDLY BEYOND THE PANEL SECTION. SUCH MEMBERS CAN BE INTERCONNECTED SIDE BY SIDE AS A FACADE FOR A STANDING WALL, OR PAIRS OF THEM CAN BE FASTENED TOGETHER, FLANGES OPPOSED, TO PROVIDE CURTAIN WALL MODULES.
