Panel system for forming poured concrete walls

Abstract

A panel system for forming poured concrete walls. The system includes at least two panels which are arranged in a spaced apart position relative to each other and form a cavity therebetween adapted to receive poured concrete. At least one attachment boss is removably mounted to at least one of the panels so that the attachment boss is positioned in the cavity and so that, following a concrete pour, the attachment boss is embedded in the concrete. A fastener is attached to the attachment boss after the concrete has set and a firring strip is thereafter attached to the fastener.

1 . A panel system for forming poured concrete walls comprising: 
 at least two panels arranged in a spaced apart position relative to each other and forming a cavity therebetween adapted to receive poured concrete,    at least one attachment boss removably mounted to at least one of said panels so that said attachment boss is positioned in said cavity, said at least one attachment boss being embedded in concrete following a concrete pour into said cavity,    a fastener attachable to said at least one attachment boss following embedment of the at least one attachment boss in concrete.    
   
   
       2 . The invention as defined in  claim 1  where said attachment boss includes an internally threaded bore and wherein said fastener comprises a threaded fastener dimensioned to threadably engage said threaded bore.  
   
   
       3 . The invention as defined in  claim 1  wherein said attachment boss is constructed of plastic.  
   
   
       4 . The invention as defined in  claim 1  and comprising a plurality of attachment bosses being removably mounted to said at least one panel, said attachment bosses being linearly aligned with respect to each other.  
   
   
       5 . The invention as defined in  claim 1  and comprising an elongated firring strip secured to said at least one fastener.  
   
   
       6 . The invention as defined in  claim 5  wherein said fastener comprises an enlarged head and wherein said firring strip includes a retainer channel dimensioned to frictionally lock onto said enlarged head.  
   
   
       7 . The invention as defined in  claim 6  wherein said retainer channel is made of a flexible material and includes at least one retaining barb, said retaining barb extending beneath said enlarged head when said enlarged head is positioned in said retainer channel.  
   
   
       8 . The invention as defined in  claim 6  wherein said firring strip comprises a plastic extrusion.  
   
   
       9 . The invention as defined in  claim 6  and comprising means for adjusting the distance between said enlarged head and said attachment boss.  
   
   
       10 . The invention as defined in  claim 9  wherein said adjusting means comprises a threaded connection between said fastener and said attachment boss.  
   
   
       11 . The invention as defined in  claim 1  and comprising a channel member secured to said panel, said channel having a cavity dimensioned to receive an end of said fastener and retain said fastener at a predetermined position relative to said panel.  
   
   
       12 . The invention as defined in  claim 1  wherein said attachment boss includes a main body having one end mounted to said panel and a retainer flange at its opposite end, said retainer flange being greater in cross-sectional area than said main body.  
   
   
       13 . The invention as defined in  claim 1  wherein said attachment boss is solid in cross section.  
   
   
       14 . The invention as defined in  claim 1  wherein said attachment boss includes a threaded bore and wherein said fastener comprises a threaded end which threadably engages said attachment boss bore and a barbed end.
