Grid-like building panel framework

Abstract

A framework type building panel having opposed first and second sides is formed of primary and secondary structural members, each primary member having a web and a flange connected to form a T-shaped cross-section, and each secondary member being a flat board having parallel side surfaces. The panel includes a first series of the primary members which are parallel to each other with their flanges defining the first side of the panel, and a second series of the secondary members which extend transversely to the primary members and have outer side surfaces defining the second side of the panel, the primary members having their web outer edges attached to inner overlying surfaces of the secondary members. The panel further includes two additional flat boards forming the opposite ends of said panel and each connected to aligned ends of said primary members.

1 . A framework type rectangular building panel, having opposed first and second sides, first and second opposite ends and first and second opposite edges, said panel being formed of a plurality of primary and secondary structural members of wood based material, 
 wherein each said primary member has a web and a flange connected to form a T-shaped cross-section, said flanges being suitable for receiving nails, and wherein each said secondary member is in the form of a flat board having parallel side surfaces,    the panel including a first series of said primary members which are spaced apart and parallel to each other with their flanges defining the first side of the panel, and a second series of said secondary members which are spaced apart and parallel to each other and extend transversely to said primary members and have outer side surfaces defining the second side of the panel, the primary members of said first series having their web outer edges attached to inner overlying surfaces of the secondary members,    the panel further including two additional said secondary members forming said opposite ends of said panel and each connected to aligned ends of said primary members.    
   
   
       2 . A panel according to  claim 1 , wherein the primary members include an edge member which is parallel to, and has the same dimensions as, the primary members of said series but which is rotated 90° about a longitudinal axis relative to the primary members of said series, said edge member having its web directed inwardly of the panel and having an outer edge of its flange connected to said inner surfaces of the secondary members, said flange comprising a first outer edge of the panel, 
 and wherein said primary members are dimensioned so that said flange comprising the first outer edge of the panel is equivalent in width to the web of a primary member at the second edge of the panel and is suitable for fitting closely against the second edge primary member web of an adjacent similar panel.    
   
   
       3 . A panel according to  claim 1 , wherein the width of each secondary member is equivalent to the overall depth of the panel, which includes the width of the web and the thickness of the flange of each primary member, plus the thickness of the secondary members.  
   
   
       4 . A panel according to  claim 2 , wherein the width of each secondary member is equivalent to the overall depth of the panel, which includes the width of the web and the thickness of the flange of each primary member, plus the thickness of the secondary members.  
   
   
       5 . A panel according to  claim 1 , wherein said primary members are identical and are dimensioned so that each said flange has a width “A” equal to the width “B” of its web, and each flange is equal in thickness “t” to that of the secondary member, and wherein the overall depth of the panel is equivalent to the flange width “A” plus twice the thickness dimension “It”.  
   
   
       6 . A panel according to  claim 1 , wherein both said primary and secondary members are free of notches.  
   
   
       7 . A panel according to  claim 2 , wherein both said primary and secondary members are free of notches.  
   
   
       8 . A panel according to  claim 3 , wherein both said primary and secondary members are free of notches.  
   
   
       9 . A panel according to  claim 4 , wherein both said primary and secondary members are free of notches.  
   
   
       10 . A panel according to  claim 1 , which also includes one or more duplex primary members, each such duplex primary member including two members each having a flange and a web connected to form a T-shaped cross-section and in which one side of a web is positioned at the centerline of the connected flange, said two members being connected with oppositely directed webs overlapping and with their flange edges co-planar, 
 said duplex primary members being arranged with inner flange edges connected to overlying secondary members and with their webs parallel to the sides of the panel.    
   
   
       11 . A framework type rectangular building panel, having opposed first and second sides, first and second opposite ends and first and second opposite edges, said panel being formed of a plurality of primary and secondary structural members of wood based material, 
 wherein said primary members are duplex primary members, each such member including two T-shaped members, each said T-shaped member having a flange and a web connected to form a T-shaped cross-section and in which one side of a web is positioned at the centerline of the connected flange, said two T-shaped members being connected together with their webs oppositely directed and overlapping and connected, and with their flange edges co-planar, and wherein each said secondary member is in the form of a flat board having parallel side surfaces,    the panel including a first series of said duplex primary members which are spaced apart and parallel to each other with their flanges edges adjacent to and parallel to the first side of the panel, and a second series of said secondary members which are spaced apart and parallel to each other and extend transversely to said duplex primary members and have outer side surfaces defining the second side of the panel, the duplex primary members of said first series having inner flange edges attached to inner overlying surfaces of the secondary members.    
   
   
       12 . The panel according to  claim 11 , further including two additional said secondary members forming said opposite ends of said panel and each connected to aligned ends of said duplex primary members.  
   
   
       13 . A panel according to  claim 11 , wherein said T-shaped members are identical and are dimensioned so that each said flange has a width “A” equal to the width “B” of its web, and each flange is equal in thickness “t” to that of the secondary members, and wherein the overall depth of the panel is equivalent to the flange width “A” plus twice the thickness dimension “t”.
