Abstract SEVERAL PROFILED MEMBERS OF METAL OR OTHER RESILIENT MATERIAL, EACH WITH ONE OR MORE PAIRS OF PARALLEL FLANGES HELD TOGETHER BY A TRANSVERSE WEB, ARE INTERCONNECTABLE BY TONGUE-AND-GROOVE FORMATIONS EXTENDING ALONG THE FREE EDGES OF THEIR FLANGES. THE INTERCONNECTED MEMBERS ARE LOCKED IN POSITION BY A BAR DISPOSED TRANSVERSELY TO THESE MEMBERS AND PROVIDED WITH TENONS INSERTED ENDWISE INTO THE CHANNEL FORMED BETWEEN THE WEBS AND FLANGES OF ADJOINING MEMBERS, THEREBY PREVENTING THEIR UNTIMELY DISENGAGEMENT WHILE REINFORCING THE STRUCTURE.
