Beschreibung
Zusammenfassung:	An elongate bolt having a head at its upper end and a threaded lower end is mounted through a corrugated sheet steel member of a steel floor deck. The threaded lower end comprises a stud formation which carries an elongate nut which provides a downwardly opening interior threaded socket. The bolt is mounted in a hole drilled in the horizontal portion of the corrugated sheet steel member and is held in place by the resilient splayed fingers of a ring engaging the bolt below the sheet of steel and a helical spring backed against a shoulder of the bolt and engaging the upper surface of the corrugated sheet of steel through a large washer. When concrete is poured on the upper surface of the sheet steel member and set, it will embed the upper portion of the bolt. Prior to pouring, however, the upper portion of the bolt is yieldable by reason of the helical spring but recoverable to a position perpendicular to the plane of the sheet steel member.
