Press-formable light-gauge truss framing element

Abstract

A press-formable light-gauge truss framing element which comprises a longitudinal constructional beam having a uniform generally T-shaped cross-section, in which a generally vertical portion of said cross-section defines a web of said beam and a transverse horizontal upper portion thereof defines symmetric opposing portions of a hollow solid rectangle. An upper-most outer surface of each of said portions includes longitudinal channels thereon. The beam comprises a material having a thickness in a range of about 10 to about 22 gauges and having a yield strength in a range of about 36 to about 55 kips per square inch and, prior to press-shaping, a width of about one foot.

1 . A press-formable light-gauge truss framing element, comprising: 
 a longitudinal constructional beam having a uniform generally T-shaped cross-section, in which a generally vertical portion of said cross-section defines a web of said beam and a transverse horizontal upper portion thereof defines symmetric opposing portions of a hollow solid rectangle, an upper-most outer surface of each of said portions including longitudinal channels thereon, further in which said beam comprises a material having a thickness in a range of about 10 to about 22 gauges and having a yield strength in a range of about 36 to about 55 kips per square inch.    
   
   
       2 . The framing element as recited in  claim 1 , in which said material of said beam comprises a sheet of material having a width of about one foot and length equal to the length of said beam, prior to its pressure forming into a desired geometry of said beam.  
   
   
       3 . A press-formable light-gauge truss framing element, comprising: 
 a longitudinal constructional beam having a uniform generally T-shaped cross-section, in which a generally vertical portion of said cross-section defines a web of said beam and a transverse horizontal upper portion thereof defines symmetric opposing portions of both a hollow solid rectangular upper portion and two legs of a triangular lower portion formed integrally medially between said web and said rectangular upper portion, an upper-most outer surface of each of said portions including longitudinal channels thereon, further in which said beam comprises a material having a thickness in a range of about 10 to about 22 gauge and having a yield strength in a range of about 36 to about 55 kips per square inch.    
   
   
       4 . The framing element as recited in  claim 3 , in which said material of said beam comprises a sheet of material having a width of about one foot and length equal to the length of said beam, prior to its pressure forming into a desired geometry of said beam.
