  • Patent number: 8491244
    Abstract: A wedge-type anchor assembly, capable of meeting cracked concrete testing standards, comprises an anchor bolt component and a substantially C-shaped expansion sleeve component annularly disposed about the anchor bolt component. A plurality of annular grooves, threads, or teeth are disposed only about the forward end portion of the expansion sleeve component, as opposed to throughout the entire axial length thereof, so that when the anchor bolt component is moved axially through the expansion sleeve component, the maximum interference area (M.I.A.) and maximum interference volume (M.I.V.) can be generated between the anchor bolt component and the expansion sleeve component in a controlled and predictable manner, as well as between the expansion sleeve component and the internal peripheral side wall portions of a concrete substrate or substructure can be generated so as to enhance pull-out resistance and reliability of the anchor assembly within the concrete substructure or substrate.
