Connecting tie for metal concrete pouring forms

Abstract

A connecting tie for use with a metal concrete pouring form. The tie includes an elongated flat bar adapted for attachment at each end to a metal pouring form to hold two forms in a spaced apart and parallel relationship thereby forming a concrete receiving cavity therebetween. A resilient seal is disposed transversely across each side of the bar adjacent each end of the bar in order to seal the tie to the metal forms.

1 . A connecting tie for use with metal concrete pouring forms comprising:
 an elongated flat bar adapted for attachment at each end to a metal pouring form,   a resilient seal disposed transversely across each side of said bar adjacent each end of said bar.   
   
   
       2 . The invention as defined in  claim 1  wherein said seal comprises a compressible polymeric material. 
   
   
       3 . The invention as defined in  claim 1  wherein said bar comprises at least one transversely inwardly extending notch adjacent each seal. 
   
   
       4 . The invention as defined in  claim 1  and comprising a through hole extending normally through each end of said bar adjacent said seal. 
   
   
       5 . A concrete pouring system comprising:
 at least two metal concrete pouring forms, each form having spaced apart sides, a top, a bottom and face wall extending between said sides, top and bottom, said forms being positioned such that said face walls of said forms are spaced apart from each other and form a concrete receiving cavity therebetween,   an elongated flat tie extending normally between said forms along the sides of said forms so that one end of said tie flatly abuts against one side of one form and the other end of said tie flatly abuts against one side of the other form,   a flexible seal disposed transversely across each side of said bar adjacent each end of said bar so that said seal seals said tie to said forms.   
   
   
       6 . The invention as defined in  claim 5  wherein said seal comprises a compressible polymeric material. 
   
   
       7 . The invention as defined in  claim 5  wherein said tie comprises at least one transversely inwardly extending notch adjacent each seal. 
   
   
       8 . The invention as defined in  claim 5  and comprising a through hole extending normally through each end of said tie adjacent said seal. 
   
   
       9 . The invention as defined in  claim 5  wherein each form includes a plurality of notches along each side, each notch having a predetermined height and width and comprising a spacer having a seal along one side, said spacer having a height and width substantially the same as said notch so that, with said spacer positioned in said notch, said spacer fills said notch and said seal simultaneously seals said spacer to said form. 
   
   
       10 . The invention as defined in  claim 9  wherein said form includes a hole extending normally to and aligned with said notch and comprising a fastener attached to said spacer and extends into said hole to secure said spacer to said form. 
   
   
       11 . The invention as defined in  claim 10  wherein said fastener comprises a spring clip.
