Abstract
An anchoring assembly, in particular for use in a composite concrete and structural steel beam, consists of a cylindrical container shaped member open at one end and closed at the other with an opening extending through the closed end. A fastening stud is positioned in the bore in the member adjacent the open end and it is arranged to be driven through the bore into a receiving material, for instance, a structural steel member, by an explosive powder actuated setting gun. The fastening stud has an elongated shank with a larger diameter head at one end and a washer fitted on the shank and spaced axially from the head. The radially outer surfaces of the head and washer act as guide surfaces as the stud is driven through the bore into the receiving material. The opening through the closed end has an axially extending frusto-conically shaped section diverging toward and terminating in the outer surface of the closed end.
