Concrete product cage spacer

Abstract

A spacer for spacing the reinforcing cage from the forms used in making concrete products. The spacer is made of concrete or a geopolymer material and has a pair of spaced-apart notches, one T-shaped and one L-shaped that provide for simple, quick installation on adjacent horizontal wires of the reinforcing cage. When locked into place, the shape of the spacer provides the desired cover, the amount of which depends upon the size of the spacer when formed.

1 . A spacer used in making concrete products such as pipes, the spacer maintaining a desired distance between the wire reinforcing cage having spaced-apart horizontal wires and the concrete forms used for forming the concrete product, the spacer comprising:
 a generally rectangular-shaped main body having a front edge, a back edge and rounded ends, the back edge having a pair of spaced-apart notches, the notches being spaced apart a distance so as to be engageable with two adjacent horizontal wires on the cage to lock the spacer onto the cage.   
     
     
         2 . The spacer of  claim 1  in which one of the notches in the main body is somewhat L-shaped and the other notch is somewhat T-shaped. 
     
     
         3 . The spacer of  claim 2  in which the L-shaped notch is above the T-shaped notch when the spacer is positioned on the wire cage. 
     
     
         4 . The spacer of  claim 3  in which the T-shaped notch is elongated so that the spacer is capable of being used on wire cages with different spacing between horizontal 
     
     
         5 . The spacer of  claim 1  that is made of concrete. 
     
     
         6 . The spacer of  claim 1  that is made of a geopolymer material.
