Wire corner bead for stucco

Abstract

A welded wire corner bead comprising at least one and preferably two continuous wires defining a periodic wave form extending from side to side of the bead, the bead being bent lengthwise along an axis.

1 . A welded wire corner bead being defined in two planes about a longitudinal axis, and having a length and a lateral extent spanning said two planes, comprising: 
 at least three parallel longitudinal wires, at least one of said longitudinal wires lying in each of said planes;    at least two continuous wires attached to each of said longitudinal wires; and,    said at least two continuous wires each defining a periodic waveform spanning said two planes across said longitudinal axis, said periodic waveform having a longitudinal extent and an amplitude substantially equal to said lateral extent of said bead.    
   
   
       2 . The welded wire corner bead of  claim 1  wherein said at least two continuous wires define identical periodic waveforms but that are out of phase with one another along said length of said corner bead.  
   
   
       3 . The welded wire corner bead according to claims  1  or  2  wherein each of said planes comprises at least one of said longitudinal wires disposed on said corner bead so as to form a plurality of nailing loops between portions of said longitudinal wire and apices of said periodic waveform.  
   
   
       4 . The welded wire corner bead according to claims  1  or  2  wherein one of said longitudinal wires lies along said longitudinal axis.  
   
   
       5 . A welded wire corner bead being defined in two planes about a longitudinal axis so as to have contiguous inside faces and contiguous outside faces of said corner bead, comprising: 
 at least three parallel longitudinal wires;    at least one continuous wire attached to each of said longitudinal wires, said at least one continuous wire defining a periodic waveform; and,    wherein all of said at least three parallel longitudinal wires are disposed on said outside faces.    
   
   
       6 . The welded wire corner bead according to claims  1  or  2  wherein said corner bead includes contiguous inside faces and contiguous outside faces and all of said at least three parallel longitudinal wires are disposed on said outside faces.  
   
   
       7 . A method of manufacturing the welded wire corner bead according to claims  1  or  2  wherein at least two of said longitudinal wires are disposed in opposed spaced relation to said longitudinal axis according to a predetermined thickness of stucco for which said corner bead is intended to be used.  
   
   
       8 . A method of manufacturing the welded wire corner bead according to claims  1  or  2  comprising the step of selecting the location of at least two of said longitudinal wires on said corner bead according to one of a plurality of predetermined thicknesses of stucco for which said corner bead could be used.  
   
   
       9 . The welded wire corner bead according to claims  1  or  2  wherein said longitudinal wires are of a different thickness than said continuous wire or wires.  
   
   
       10 . The welded wire corner bead according to claims  1  or  2  wherein at least one of said wires has a non-circular shape.  
   
   
       11 . The welded wire corner bead according to claims  1  or  2  wherein said longitudinal wires have a fluted shape twisted spirally along their length.  
   
   
       12 . The welded wire corner bead according to claims  1  or  2  wherein each of said periodic waveforms comprises straight sections extending between curved apices.  
   
   
       13 . The welded wire corner bead according to claims  1  or  2  wherein each of said periodic waveforms has apices that include a distinct straight portion that is parallel to said longitudinal axis.  
   
   
       14 . The welded wire corner bead according to claims  1  or  2  wherein said at least two continuous wires have points of overlapping intersection between them and said longitudinal wires are disposed away from said points of overlapping intersection so that the presence of said longitudinal wires does not increase the effective thickness of said corner bead in the vicinity of said points of intersection.  
   
   
       15 . A method of manufacturing the welded wire corner bead according to claims  1  or  2  comprising the steps of disposing said longitudinal wires away from points of overlapping intersection between said at least two continuous wires, and welding said longitudinal wires to said continuous wires such that the thickness of said corner bead does not exceed two wire thicknesses throughout said welded wire corner bead.  
   
   
       16 . The welded wire corner bead according to  claim 1  wherein said corner bead includes contiguous inside faces and contiguous outside faces and all of said at least three parallel longitudinal wires are disposed on said outside faces and wherein said periodic waveform comprises straight sections extending between curved apices.  
   
   
       17 . The welded wire corner bead according to  claim 16  wherein said at least two continuous wires have points of overlapping intersection between them and said longitudinal wires are disposed away from said points of overlapping intersection so that the presence of said longitudinal wires does not increase the effective thickness of said corner bead in the vicinity of said points of intersection.
