Abstract
A drop-in anchor includes a sleeve having a threaded region having an internal thread formed therein and a split region having at least two longitudinal channels formed therein. The channels define sections. The split region has inwardly tapered inner walls. A plug is configured for engagement with the sleeve at the split region. The plug has a top surface and defines a tapered shape. A bolt having a threaded portion and a through-bore extending longitudinally therethrough, is configured for threaded engagement with the sleeve threaded region. A setting member is configured for insertion into the bolt bore. The setting member engages the plug top surface and a force exerted on the setting member drives the plug into the sleeve split region so as to urge the split region sections axially outwardly. A method for securing the anchor in the opening in the structure is also disclosed.
