Concrete anchor bolt holder

Abstract

The present invention is a reusable anchor bolt holder having a generally annular column that detachably secures to and covers a concrete anchor bolt by a plurality of attachment members which secure to the threads of the anchor bolt. The annular column secures the anchor bolt in a vertically fixed position by means of a rotatably hinged wall support bracket that connects the annular column to a wooden retainer wall by being forcefully lowered onto the top surface of the wooden retainer wall. The wall support bracket has a spiked contact face, which when downward force is applied, is inserted and securely attached to the retainer wall, thereby keeping the anchor bolt in place. The wall support bracket can be removed from the retainer wall with an upward force, thereby rotating the contact portion of the bracket to a vertical position. The top of the annular column of the device mates with, or is formed to create an integrated safety cap of a larger surface area to prevent injury.

       12 . An anchor bolt positioning apparatus comprising: 
 a. an annular column with a plurality of engagement members extending radially inward to secure the annular column to an upper portion of an anchor bolt wherein said annular column encircles said upper portion of the anchor bolt;    b. a plurality of wall support brackets pivotally attached to said annular column, said wall support brackets having at least one contact face, each such contact face having at least one attachment spike thereon for temporary engagement with a retainer wall.    
   
   
       13 . The anchor bolt positioning apparatus of  claim 12  wherein said annular column further comprises a safety cap attachment member which mates with a corresponding attachment point of an anchor bolt safety cap to secure said cap to said annular column.  
   
   
       14 . The anchor bolt positioning apparatus of  claim 12  wherein said annular column further comprises a safety cap on the upper end of the annular column having a greater surface area than the top surface of the annular column.  
   
   
       15 . An anchor bolt positioning apparatus comprising: 
 a. an annular column having a plurality of engagement members extending radially inward to secure the annular column to an upper portion of an anchor bolt wherein said annular column encircles said upper portion of the anchor bolt;    b. a wall support bracket pivotally attached to said annular column, said wall support bracket having at least one contact face, each such contact face having at least one attachment spike thereon for temporary engagement with a retainer wall;    said wall support bracket rotates at least 90° in an arcuate path; said at least one attachment spike is made from a hardened material that is secured to the hinged section; said contact faces are tiered; said wall support bracket further comprises a wall stop extending downwardly from said bracket; said wall support bracket further comprises a lower strike surface which extends laterally beyond the contact faces; wherein said annular column further comprises a safety cap attachment member which mates with a corresponding attachment point of an anchor bolt safety cap to secure said cap to said annular column.    
   
   
       16 . An anchor bolt positioning apparatus comprising: 
 a. an annular column having a plurality of engagement members extending radially inward to secure the annular column to an upper portion of an anchor bolt wherein said annular column encircles said upper portion of the anchor bolt;    b. a wall support bracket attached to said annular column, said wall support bracket having at least one contact face, wherein said contact face temporary engages with a retainer wall;    wherein said annular column further comprises a safety cap attachment member which mates with a corresponding attachment point of an anchor bolt safety cap to secure said cap to said annular column.    
   
   
       17 . An anchor bolt positioning apparatus comprising: 
 a. an annular column having engagement means extending inward to secure the annular column to an upper portion of an anchor bolt wherein said annular column encircle said upper portion of the anchor bolt;    b. a wall support means attached to said annular column, said wall support means having at least one contact means for temporary engagement with a retainer wall.    
   
   
       18 . The anchor bolt positioning apparatus of  claim 17  wherein said annular column further comprises a safety cap attachment means to secure a safety cap to said annular column.
