    摘要: The apparatus for anchoring a bolt includes an elongated bolt with a threaded portion located at a preselected position along the length of the bolt and spaced from the end portions of the bolt. An expansion shell assembly is positioned on the bolt with the camming plug portion threadedly secured to the bolt threaded portion so that the expansion shell assembly is positioned in spaced relation to the ends of the bolt. In one embodiment, the threaded portion of the bolt includes a threaded sleeve suitably secured to the bolt at a location between the end portions of the bolt. In another embodiment, the bolt has a threaded portion located between the unthreaded end portions and a C-shaped stop member is secured on the lower portion of the threads. A camming plug is formed in longitudingal halves that are positioned around the threaded portion of the bolt and held in place by the fingers of the expansion shell assembly. A method is also disclosed where the threaded portion of the bolt is located at a preselected location between the ends of the bolt and the expansion assembly is threadedly engaged to the threaded portion of the bolt at the preselected location and is expanded to engage the bore hole at that location. A chamical bond may be employed to engage another portion of the bolt to the bore hole.
