Concrete wall form tie

Abstract

A concrete wall form having spaced-apart wall forms forming opposing surfaces that define a cavity for forming a concrete wall are provided with a plurality of improved lighter weight wall form ties that hold the walls in a desired relationship. The improved wall form tie includes an elongate strip of material having two opposite elongate edges and a fastening aperture defined at each of two opposite ends of the elongate strip for attachment of the wall tie to wall forms. A plurality of notches spaced-apart along each of the two opposite elongate edges of the strip between the fastening apertures facilitate proper placement and retention of reinforcing bars in a cavity defined between the concrete wall forms. Weight-reducing apertures defined within an area between adjacent notches provide recyclable scrap material and reduce the weight of the wall form tie, thereby reducing manufacturing and freight costs.

1 . A concrete wall form tie comprising: 
 an elongate strip of material having two opposite elongate edges and a fastening aperture defined at each of two opposite ends of the elongate strip of material, a plurality of notches spaced-apart along each of the two opposite elongate edges of the strip between the fastening apertures, and weight-reducing apertures defined within an area between adjacent notches.    
   
   
       2 . The concrete wall form tie of  claim 1 , wherein the smallest total cross-sectional area of the elongate strip at a plane transverse to the length direction of the strip passing through the weight-reducing aperture is greater than the smallest total cross-sectional area of the elongate strip at a plane transverse to the length direction of the strip passing through either fastening aperture.  
   
   
       3 . The concrete wall form tie of  claim 1 , wherein the strip of material is metal.  
   
   
       4 . The concrete wall form tie of  claim 1 , wherein the strip of material is steel.  
   
   
       5 . The concrete wall form tie of  claim 1 , wherein the strip of material is aluminum.  
   
   
       6 . The concrete wall form tie of  claim 1 , wherein the strip of material has a uniform thickness.  
   
   
       7 . A concrete wall form, comprising; 
 spaced-apart wall forms forming opposing surfaces that define a cavity for forming a concrete wall; and    a plurality wall form ties holding the spaced-apart wall forms together in a desired relationship, each wall form tie being connected at a first end to a first wall form and at a second opposite end to a second wall form, each wall form tie being an elongate strip having two opposite elongate edges and a fastening aperture defined at each of two opposites ends of the elongate strip, a plurality of notches spaced-apart along each to the two opposite elongate edges of the strip between the fastening apertures, and weight-reducing apertures defined within an area between the adjacent notches.    
   
   
       8 . The concrete wall form of  claim 7 , wherein the smallest total cross-sectional area of the elongate strip at a plane transverse to the length direction of the strip passing through the weight-reducing aperture is greater than the smallest total cross-sectional area of the elongate strip at a plane transverse to the length direction of the strip passing through either fastening aperture.  
   
   
       9 . The concrete wall form of  claim 7 , wherein the strip of material is metal.  
   
   
       10 . The concrete wall form of  claim 7 , wherein the strip of material is steel.  
   
   
       11 . The concrete wall form of  claim 7 , wherein the strip of material is aluminum.  
   
   
       12 . The concrete wall form of  claim 7 , wherein the strip of material has a uniform thickness.
