Abstract
An anchor bolt assembly is provided and comprises an anchor bolt having a threaded end and an anchor end wherein the anchor end is embedded in a suitable base material while the threaded end protrudes upwardly and outwardly from the base material. A tubular resilient sleeve is positioned annularly around the anchor bolt between its ends so that the sleeve is disposed between the base material and a portion of the anchor bolt. The resilient sleeve permits radial displacement of the anchor bolt relative to the base material while maintaining firm engagement between the anchor bolt and the base material.
Claims3
An anchor bolt assembly comprising:
- an anchor bolt having a threaded end and an anchor end;
- a tubular sleeve having an internal bore positioned annularly around and extending along said bolt between the ends thereof, said ends of said bolt projecting outwardly from the ends of said sleeve, wherein said sleeve is constructed of a resilient hard rubber material, said sleeve being radially inwardly compressed around said anchor bolt to thereby form a fluid seal between said sleeve and said anchor bolt so that the internal bore of said sleeve remains substantially entirely in contact with the anchor bolt despite radial displacement of the anchor bolt to thereby maintain the fluid seal between said sleeve and said bolt.
