Metal framing strut with coiled end portions

Abstract

A building strut of rectangular cylindrical construction has four contiguous, axially directed side walls. A terminal end of one or two of the four side walls is rolled into a coiled, retracted position, exposing interior surfaces of the remaining adjacent side wall terminal ends. These remaining terminal ends of the building strut are then be formed into jogged-out positions for receiving a second building strut in permanent engagement medially or at its end.

What is claimed is:  
     
         1 . A building strut apparatus comprising a rectangular cylinder having four contiguous, axially directed side walls, wherein a terminal end of at least one of the four side walls is deformed into a coiled, retracted or cut, and discarded position, exposing an interior surface of the remaining adjacent side wall terminal ends.  
     
     
         2 . A first building strut apparatus comprising a rectangular cylinder having four contiguous, axially directed side walls, wherein an opposing pair of terminal ends of the four side walls are deformed into a coiled, retracted corresponding positions, exposing an interior surface of each of the two remaining adjacent side wall terminal ends.  
     
     
         3 . The apparatus of  claim 2  wherein the deformed side walls are coiled into an interior of the cylinder.  
     
     
         4 . The apparatus of  claim 2  wherein the deformed side walls are coiled outwardly over opposing exterior surfaces of the cylinder.  
     
     
         5 . The apparatus of  claim 2  wherein the two remaining adjacent side wall terminal ends are set in outwardly jogged, axially oriented positions.  
     
     
         6 . The apparatus of  claim 5  further comprising a second building strut received within the outwardly jogged terminal ends of the first building strut and fastened thereto.
