Structural floor system

Abstract

A structural floor system is provided comprising: a plurality of I-joists; a plurality of composite wood panels attached to the plurality of I-joists, each panel having parallel first and second longitudinal edges, each panel containing a binder resin; and an adhesive composition containing the binder resin, the adhesive composition applied between on the first and second longitudinal edges.

1 . A structural floor system comprising: 
 a plurality of I-joists;    a plurality of composite wood panels attached to the plurality of I-joists, each panel having parallel first and second longitudinal edges, each panel containing a binder resin; and    an adhesive composition containing the binder resin, the adhesive composition applied between on the first and second longitudinal edges.    
   
   
       2 . The structural floor system according to  claim 1 , wherein a groove is formed along the second longitudinal edge, and a complementary shaped tongue formed along the first longitudinal edge.  
   
   
       3 . The structural floor system according to  claim 1 , wherein the plurality of composite wood panels are formed from OSB.  
   
   
       4 . The structural floor system according to  claim 1  wherein the binder resin is selected from the group comprising polyurethane resin, and isocyanate resin.  
   
   
       5 . The structural floor system according to  claim 1  wherein the I-joists comprise: 
 (a) a first flange and a second flange, at least the first flange being made from solid wood lumber; and    (b) a webstock, interconnecting the first and second flange, the webstock being composed of a wood composite material.    
   
   
       6 . The structural floor system according to  claim 1  wherein the wood composite wood panels isocyanate resin and a powdered aromatic phenol-aldehyde thermoset material  
   
   
       7 . A structural floor system comprising: 
 a plurality of I-joists;    a plurality of OSB wood panels attached to the plurality of I-joists, each panel having parallel first and second longitudinal edges, wherein a groove is formed along the second longitudinal edge, and a complementary shaped tongue formed along the first longitudinal edge; each panel further containing a binder resin, the binder resin being selected from the group comprising polyurethane resin, and isocyanate resin; and    an adhesive composition comprising containing the binder resin, the adhesive composition applied between on the first and second longitudinal edges.    
   
   
       8 . The structural floor system according to  claim 7 , wherein a groove is formed along the second longitudinal edge, and a complementary shaped tongue formed along the first longitudinal edge.
