Abstract
There is provided a unitary, strike drop-in anchor where the individual parts are permanently held together to avoid misplacing any such individual part. The anchor comprises an anchor body with a central bore, the first end of the bore being threaded and having a constant internal cross-section for the length of the threaded portion. The exterior of the anchor body, and the central bore, having a decreasing bore towards the second end of the anchor body beyond the threaded portion, a threaded bolt with an internal central bore and a preferably polygonal drive head, and external threads extending from the drive head to the second end, has a strike tool extending through the central bore from the second end and extending beyond the drive head. The strike tool has a strike head that has a diameter larger than the central bore of the threaded bolt and is adjacent the second end of the threaded bolt; a wedge slug is wedged within the central bore of the anchor body, adjacent the decreasing bore portion and is held in place within the anchor body by the threaded bolt and the strike head. When the anchor is assembled, and the anchor is placed within a hole drilled into concrete, striking the outer end of the strike tool with a hammer, causes the wedge slug to flare the narrower inner end of the anchor body, locking the anchor into the concrete.
