Abstract

A method for manufacturing an anchor bolt sleeve includes heat treating a steel blank, and cold working the steel blank into an anchor bolt sleeve subsequent to the heat treating, the anchor bolt sleeve being expandably receptive to a wedge of an anchor bolt.

Claims

exact text as granted — not AI-modified
1 . A method for making an anchor bolt sleeve comprising:
 heat treating a steel blank; and   cold working the steel blank into an anchor bolt sleeve subsequent to the heat treating, the anchor bolt sleeve being expandably receptive to a wedge of an anchor bolt.   
     
     
         2 . The method for making an anchor bolt sleeve of  claim 1 , further comprising quenching and tempering the steel blank prior to the forming of the steel blank into the sleeve. 
     
     
         3 . The method for machining an anchor bolt sleeve of  claim 2 , wherein the quenching and tempering results in hardening of the steel blank to a hardness not to exceed 35 on the Rockwell C hardness scale. 
     
     
         4 . The method for machining an anchor bolt sleeve of  claim 1 , wherein the cold working results in hardening of the steel blank to a hardness greater than 35 on the Rockwell C hardness scale. 
     
     
         5 . The method for machining an anchor bolt sleeve of  claim 1 , wherein the cold working is a process selected from the group consisting of rolling, drawing, pressing, spinning, extruding and heading. 
     
     
         6 . The method for machining an anchor bolt sleeve of  claim 1 , wherein the cold working further includes joining the two adjacent sides of the steel blank along a seam.
