Corner bead having a reinforcing member

Abstract

A corner bead for joining adjacent pieces of wallboard including an arched center section having a pair of wing sections attached thereto. The arched center section extends outwardly above planes defined by the wing sections, and the wings and arched center section define an interior surface which is placed adjacent the wallboard and an exterior surface which is placed opposite the wallboard. A reinforcing member is disposed adjacent the interior surface of the arched center section and attached thereto to provide rigidity to the arched center section.

1 . A corner bead for joining adjacent pieces of wallboard comprising: 
 an arched center section having a pair of wing sections attached thereto, the arched center section extending outwardly above planes defined by the wing sections, the wings and arched center section defining an interior surface which is placed adjacent the wallboard and an exterior surface which is placed opposite the wallboard; and    a reinforcing member disposed adjacent the interior surface of the arched center section and attached thereto to provide rigidity to the arched center section.    
   
   
       2 . The corner bead of  claim 1  wherein the reinforcing member is tempered wire.  
   
   
       3 . The corner bead of  claim 2  including an adhesive retaining the wire to the interior surface of the arched center section.  
   
   
       4 . The corner bead of  claim 1  wherein the reinforcing member is a polyamide hot melt glue.  
   
   
       5 . The corner bead of  claim 1  wherein the material is a flexible polymeric material.  
   
   
       6 . The corner bead of  claim 1  wherein the wings are covered with a plurality of discrete fibers.  
   
   
       7 . The corner bead of  claim 1  further defining a plurality of triangular cutouts in the wings that allow the corner bead to follow nonlinear intersections of wallboard.  
   
   
       8 . The corner bead of  claim 7  further comprising tear strips adjacent the triangular cutouts.  
   
   
       9 . A corner bead for joining adjacent pieces of wallboard comprising: 
 an arched center section having a pair of wing sections attached thereto, the arched center section extending outwardly above planes defined by the wing sections, the wings and arched center section defining an interior surface which is placed adjacent the wallboard and an exterior surface which is placed opposite the wallboard, wherein both the interior and exterior surface of the wings comprise a plurality of discrete fibers; and    a reinforcing member disposed adjacent the interior surface of the arched center section and attached thereto to provide rigidity to the arched center section.    
   
   
       10 . The corner bead of  claim 8  wherein the reinforcing member is, tempered wire.  
   
   
       11 . The corner bead of  claim 10  including an adhesive retaining the wire to the interior surface of the arched center section.  
   
   
       12 . The corner bead of  claim 9  wherein the reinforcing member is a polyamide hot melt glue.  
   
   
       13 . The corner bead of  claim 9  wherein the material is a flexible polymeric material.  
   
   
       14 . The corner bead of  claim 9  further defining a plurality of triangular cutouts in the wings that allow the corner bead to follow nonlinear intersections of wallboard.  
   
   
       15 . The corner bead of  claim 14  further comprising tear strips adjacent the triangular cutouts.  
   
   
       16 . A corner bead for joining adjacent pieces of wallboard comprising: 
 an arched center section having a pair of wing sections attached thereto, the arched center section extending outwardly above planes defined by the wing sections, the wings and arched center section defining an interior surface which is placed adjacent the wallboard and an exterior surface which is placed opposite the wallboard; and    a tempered wire reinforcing member disposed adjacent the interior surface of the arched center section and attached thereto to provide rigidity to the arched center section.    
   
   
       17 . The corner bead of  claim 16  wherein the material is a flexible polymeric material.  
   
   
       18 . The corner bead of  claim 16  wherein the wings are covered with a plurality of discrete fibers.  
   
   
       19 . The corner bead of  claim 16  further defining a plurality of triangular cutouts in the wings that allow the corner bead to follow nonlinear intersections of wallboard.  
   
   
       20 . The corner bead of  claim 19  further comprising tear strips adjacent the triangular cutouts.
