Passthrough concrete anchor

Abstract

The present invention is directed towards a concrete lift anchor. The concrete lift anchor of the present invention comprises a metal bar having a top, bottom and first and second sides, at least one attachment aperture, at least one reinforcement bar aperture, at least one passthrough aperture, and a shear plate aperture. The top side of the bar further comprises a first channel, a first upwardly projecting face, a platform face, a second upwardly projecting face, and a second channel. The anchor further comprises a crescent shaped indentation on the first side of the rectangular shaped bar.

         12 . The concrete anchor of  claim 8  wherein the anchor further comprises a crescent shaped indentation on the first side of the rectangular shaped bar.  
     
     
         13 . The concrete anchor of  claim 8 , wherein the at least one passthrough aperture is designed so that the weight of the anchor is reduced by at least 30%.  
     
     
         14 . A concrete anchor comprising: 
 a rectangular shaped bar having a top, bottom and first and second sides, an attachment aperture, a first reinforcement bar aperture, a second reinforcement bar aperture, a passthrough aperture, and a shear plate aperture;    wherein the top side of the bar further comprises a first channel, a first upwardly projecting face, a platform face, a second upwardly projecting face, and a second channel;    wherein the second side of the rectangular shaped bar further comprises a downwardly projecting side face, an extending side face, and an upwardly projecting side face;    wherein the shear plate aperture is adjacent to the extending side face;    wherein the anchor further comprises a wedged shaped foot located on the bottom of the rectangular shaped bar; and    wherein the anchor further comprises a crescent shaped indentation on the first side of the rectangular shaped bar.    
     
     
         15 . The concrete anchor of  claim 14 , wherein the passthrough aperture is designed so that the weight of the anchor is reduced by at least 30%.  
     
     
         16 . A concrete anchor comprising: 
 a square shaped bar having a top, bottom and first and second sides, at least one attachment aperture, at least one reinforcement bar aperture, at least one passthrough aperture, and a shear plate aperture;    wherein the top side of the bar further comprises a first channel, a first upwardly projecting face, a platform face, a second upwardly projecting face, and a second channel.    
     
     
         17 . The concrete anchor of  claim 16 , wherein the shear plate aperture is adjacent to the second side.
