Wooden Web Stiffener Having Chord Nailing Restrictor For Wooden I-joist

Abstract

A chord nailing restricting device features a chord plate combined with a wooden volume structure configured for lateral attachment to the web of a wooden I-joist. The chord plate is positioned on the bottom of the volume structure and features a nail restricting hole having a diameter that corresponds to a predetermined diameter of a chord nail as defined by wooden I-joist manufacturers. The volume structure has a chord nailing access cavity in an surrounding vicinity of the nail restricting hole. Once the device is attached to the web above the bearing rest, the nail restricting hole restricts chord nailing position and nail shaft diameter to manufacturer defined limits. Two devices may be combined by a web front bridge plate for simultaneous attachment of two opposite devices along an I-joist end.

1 . A device for restricting nailing on a wooden I-joist chord, said device comprising: 
 a. a volume structure configured for receiving and holding a web fastener across a width of said volume structure, said volume structure having: 
 i. a web face to be contacted with a web side of said wooden I- joist; and  
 ii. a chord nailing access cavity in an immediate surrounding vicinity of a nail restricting hole and at least open to a side opposite said web face such that said nail restricting hole is at least accessible from said side opposite to said web face;  
   b. a chord plate combined with said volume structure and positioned at the bottom of said volume structure, said chord plate having said nail restricting hole in a web nailing clearance to said web face, said nail restricting hole having a diameter corresponding to a predetermined chord nail diameter;    
   
   
       2 . The device of  claim 1 , wherein said nail restricting hole is in a chord front nailing clearance to a chord end flush face of said device.  
   
   
       3 . The device of  claim 1 , wherein said chord plate further comprises a centering funnel surrounding said nail restricting hole.  
   
   
       4 . The device of  claim 1 , wherein a web plate is combined in an angle with said chord plate along a web edge of said chord plate, said web plate being recessed in said volume structure behind and up to said web face.  
   
   
       5 . The device of  claim 4 , wherein said chord nailing access cavity is open to a volume structure front side such that said nail restricting hole is additionally accessible along said side lateral to said web face.  
   
   
       6 . The device of  claim 4 , further comprising a web front bridge plate combining two of said web plate in a U-profile along a volume structure height such that two of said web face are facing each other while forming a web gap, and wherein at least one of respective two of said web plate features a centrally placed fastener access cutout.  
   
   
       7 . The device of  claim 1 , wherein said volume structure is made of a material selected from a group of materials consisting of wood, wood laminate, wood like material.  
   
   
       8 . The device of  claim 1 , wherein said volume structure features a fastener position locator on said side opposite said web face.  
   
   
       9 . The device of  claim 1 , wherein said volume structure features a web connector hole protruding between said side opposite said web face and said web face.  
   
   
       10 . The device of  claim 1  being attached to a web of a wooden I-joist via said volume structure while said web edge is substantially coplanar with a side of said web, while said chord front flush edge is substantially flush with a bottom chord front of said I-joist, while said chord plate is in a snug contact with a bottom chord top, such that a buckling tendency of said web is reduced below a predetermined safety limit by said volume structure.  
   
   
       11 . A wooden I-joist web stiffening volume structure configured for lateral attachment to said web via a web fastener across a width of said volume structure, said volume structure comprising: 
 a. a chord plate combined with said volume structure and positioned at a bottom of said volume structure, said chord plate having a nail restricting hole in a web nailing clearance to a web face of said volume structure, said nail restricting hole having a diameter corresponding to a predetermined chord nail diameter;    b. a chord nailing access cavity being in an immediate surrounding vicinity of said nail restricting hole and being at least open to a side opposite said web face such that said nail restricting hole is at least accessible from said side opposite to said web face.    
   
   
       12 . The wooden I-joist web stiffening volume structure of  claim 11 , wherein said nail restricting hole is in a chord front nailing clearance to an I-joist end flush face of said volume structure.  
   
   
       13 . The wooden I-joist web stiffening volume structure of  claim 11 , wherein said chord plate further comprises a centering funnel surrounding said nail restricting hole.  
   
   
       14 . The wooden I-joist web stiffening volume structure of  claim 11 , wherein a web plate is combined in an angle with said chord plate along a web edge of said chord plate, said web edge being substantially coplanar with said web face and said web plate being recessed in said volume structure behind and up to said web face.  
   
   
       15 . The wooden I-joist web stiffening volume structure of  claim 14 , wherein said chord nailing access cavity is open to a volume structure front side such that said nail restricting hole is additionally accessible along said side lateral to said web face.  
   
   
       16 . The wooden I-joist web stiffening volume structure of  claim 14 , further comprising a web front bridge plate combining two of said web plate in a U-profile along a volume structure height such that two of said web face are facing each other while forming a web gap, and wherein at least one of respective two of said web plate features a centrally placed fastener access cutout.  
   
   
       17 . The wooden I-joist web stiffening volume structure of  claim 11 , wherein said volume structure is made of a material selected from a group of materials including wood, wood laminate, wood like material.  
   
   
       18 . The wooden I-joist web stiffening volume structure of  claim 11 , wherein said volume structure features a fastener position locator on said side opposite said web face.  
   
   
       19 . The wooden I-joist web stiffening volume structure of  claim 11 , wherein said volume structure features a web fastener hole protruding between said side opposite said web face and said web face.  
   
   
       20 . The wooden I-joist web stiffening volume structure of  claim 11  being attached to said web via said volume structure while said web face is contacting said web, while said chord front flush face is substantially flush with an end of said I-joist and while said chord plate is in a snug contact with a bottom chord top, such that a buckling tendency of said web is reduced below a predetermined safety limit by said volume structure.
