Marking System & Method For Use In Concrete Anchors

Abstract

The present invention provides for a marking system for use in concrete anchors, wherein the system is comprised of a setting tool with a rib to contact the anchor. Upon contact, the setting tool and the rib abrade a surface of the anchor and simultaneously create a score mark in order to indicate to the user of the concrete anchor that said anchor has been properly set. The entire anchor can also be pre-dipped into a lubricating substance to further facilitate the setting of the anchor.

1 . A marking system for use in drop-in anchors comprising:
 (a) an anchor further comprised of an upper surface and spreading lamellae;   (b) a bullet positioned in the anchor to set the anchor;   (c) a setting tool to drive the bullet downwardly further comprised of:
 (i) a collar; and, 
 (ii) a rib positioned on the collar; 
   
       wherein the collar and rib of the setting tool contact the upper surface of the anchor to create a score mark on the upper surface which provides a visual indicator that the anchor has been set. 
     
     
         2 . The marking system of  claim 1  wherein the collar is further comprised of at least two ribs. 
     
     
         3 . The marking system of  claim 1  wherein the upper surface of the anchor is further comprised of an abradable coating, the abradable coating serving as a second visual indicator that the anchor has been set. 
     
     
         4 . The marking system of  claim 3  wherein the abradable coating is paint. 
     
     
         5 . The marking system of  claim 1  wherein the rib is pyramidally-shaped. 
     
     
         6 . The marking system of  claim 1  wherein the anchor and bullet have been coated with a lubricating substance. 
     
     
         7 . The marking system of  claim 1  wherein the collar is further comprised of a fastener and set screw. 
     
     
         8 . The marking system of  claim 1  wherein the rib is a brazed carbide on the collar. 
     
     
         9 . A method of setting an anchor, the steps comprising:
 (a) positioning an anchor shell further comprised of an abradable upper surface and a bullet within a bore hole;   (b) striking the anchor and bullet with a setting tool further comprised of a rib;   
       wherein the striking of the anchor will create a score mark on the upper surface of the anchor to provide visual confirmation that the anchor has been set.
