Floor structure

Abstract

A floor structure to support a building has I-beam floor joists in parallel spaced-apart relation, a plurality of rectangular pans supported on the I-beams and defined between respective pairs of U-shaped vertical members, and upper and lower closely spaced adhesive layers with fabric matting therebetween to close the bottoms of the pans.

1 . A floor structure for supporting a building, comprising: 
 a plurality of I-beam floor joists disposed in spaced-apart generally parallel relation and comprising a sub-floor,    a plurality of generally rectangular pans supported on and secured to the I-beams, respective ones of said pans being defined between respective pairs of U-shaped members extending generally vertically and welded back-to-back,    plastic foam blocks disposed in the respective pans between the U-shaped members, and    upper and lower closely spaced layers of adhesive with fabric matting disposed therebetween to close the bottoms of said pans.    
   
   
       2 . A floor structure according to  claim 1  wherein said I-beam floor joists are formed of steel.  
   
   
       3 . A floor structure according to  claim 1  wherein said pans are secured to said I-beams by threaded fasteners.  
   
   
       4 . A floor structure according to  claim 1  wherein said pans are of generally rectilinear configuration.  
   
   
       5 . A floor structure according to  claim 1  wherein said plurality of rectilinear pans are disposed in three transverse rows.  
   
   
       6 . A floor structure according to  claim 1  and further comprising a mesh screen mounted generally horizontally atop upper horizontal portions of said U-shaped members mounted back-to-back.  
   
   
       7 . A floor structure for supporting a building, comprising: 
 a plurality of I-beam floor joists disposed in spaced-apart generally parallel relation and comprising a sub-floor,    a plurality of generally rectangular pans supported on and secured to the I-beams, respective ones of said pans being defined between respective pairs of U-shaped members to extend generally vertically and welded back-to-back,    plastic foam blocks disposed in the respective pans between the U-shaped members,    a body of concrete disposed above said plastic foam blocks to provide structural strength, and    upper and lower closely spaced layers of adhesive with fabric matting disposed therebetween to close the bottoms of said pans.    
   
   
       8 . A floor structure according to  claim 7  wherein said I-beam floor joists are formed of steel.  
   
   
       9 . A floor structure according to  claim 7  wherein said pans are secured to said I-beams by threaded fasteners.  
   
   
       10 . A floor structure according to  claim 7  wherein said plurality of pans are disposed in three transverse rows.  
   
   
       11 . A floor structure according to  claim 7  wherein said body of concrete extends above and below said screen.  
   
   
       12 . A floor structure for supporting a building, comprising: 
 a plurality of I-beam floor joists disposed in spaced-apart relation and comprising a sub-floor,    a plurality of pans supported on the I-beams, respective ones of said pans being defined between respective pairs of U-shaped members extending generally vertically,    said U-shaped members being welded in back-to-back relation,    plastic foam blocks disposed in respective ones of said pans and between the U-shaped members,    a mesh screen mounted generally horizontally atop upper horizontal portions of said U-shaped members mounted back to back,    upper and lower closely spaced layers of adhesive with fabric matting therebetween and positioned to close the bottoms of said pans.    
   
   
       13 . A floor structure according to  claim 12  wherein said I-beam floor joists are formed of steel.  
   
   
       14 . A floor structure according to  claim 12  wherein said pans are secured to said I-beams by threaded fasteners.  
   
   
       15 . A floor structure according to  claim 12  wherein said pans are of generally rectilinear configuration.  
   
   
       16 . A floor structure according-to  claim 12  wherein said plurality of pans are disposed in three transverse rows.
