Floor truss systems and methods

Abstract

A flooring truss system is disclosed for carrying sub-flooring materials such as a radiant heat source. A plurality of truss members carry a deck, foam, concrete, and tubing.

1 . A floor truss system comprising: 
 a plurality of trusses spaced apart and extending between wall structures, said trusses comprising a bottom chord, a top chord, a first and a second end web, at least one center web, said first and second end webs coupled between said top and bottom chords, and said first, second, and end webs having flanges extending above said top chord;    a support structure between adjacent trusses, said support structure carrying at least one tube, and said support structure carrying a floor layer.    
   
   
       2 . A floor truss system according to  claim 1 , said floor truss system further comprising a decking material carried by adjacent trusses.  
   
   
       3 . A floor truss system according to  claim 1 , said floor truss system further comprising reinforcement bars carried in said floor layer.  
   
   
       4 . A floor truss system according to  claim 1 , wherein said top and bottom chords are each two ply.  
   
   
       5 . A floor truss system according to  claim 1 , wherein said center web, said first and second end webs form a flange above said top chord.  
   
   
       6 . A floor truss system according to  claim 1 , said floor truss system further comprising an end plate supporting said top chord on said wall structure.  
   
   
       7 . A floor truss system according to  claim 1 , wherein said tube carries radiant heating material.  
   
   
       8 . A floor truss system according to  claim 1 , wherein radiant heating material is water.
