Building truss structure

Abstract

A building truss that is light weight, and easily manipulated yet provides superior strength for support is disclosed. The building truss is defined by a pair of parallel and spaced apart square tubing members, having joined between them, a lattice of cold rolled round reinforcing rod having a sinusoidal or zig-zag pattern. Additional spacers are provided to prevent twisting. Also, angled reinforcing pieces may be attached to the lattice for increased load bearing capabilities.

I claim:  
     
         1 . A building truss comprising: 
 a first elongated member formed of square cross-section hollow metallic tubing;    a second elongated member formed of square cross-section hollow metallic tubing;    said first elongated member being parallel to said second elongated member, separated by a predetermined distance; and    a third member formed of a round cross-section solid reinforcing metallic rod, said third member having a plurality of first bends and a plurality of second bends, said first bends and said second bends being alternately disposed thereby forming a sinusoidal pattern having a height substantially equal to the predetermined distance;    means for fixedly attaching said plurality of first bends to said first elongated member; and    means for fixedly attaching said plurality of second bends to said second elongated member;    wherein said third member being a lattice between said first and second elongated members.    
     
     
         2 . The building truss according to  claim 1 , further comprising: 
 a plurality of angled metallic members disposed between said first bends and said second bends of said sinusoidal lattice; and    means for fixedly attaching said plurality of angled metallic members to said lattice.    
     
     
         3 . The building truss according to  claim 1 , further comprising: 
 a plurality of first metallic spacer members disposed between selected said first bends and said second elongated member;    a plurality of second metallic spacer members parallel to said first metallic spacer members and disposed between selected said second bends and said first elongated member; and    means for fixedly attaching said plurality of first and second metallic spacer members to respective said selected first bends and second elongated member, and said selected second bends and said first elongated member;    wherein said first and second spacer members prevent twisting of the building truss.
