ABSTRACT:
A deck anchor, for securing in a hole in a metal plate in concrete building structures, has a stem with a connector at one end, and an assembly slidable on said stem and urged by spring loading towards the connector. The assembly includes a washer, and a collar portion, initially integrally joined by rupturable bridging means. When the anchor is driven, by force applied on the stem, to thrust the assembly through a hole in a deck plate, the collar portion is separated from the washer, such that the anchor becomes retained in the hole of the deck plate with the washer spring-urged against one major face of the deck plate, and the collar urged against the other major face of the deck plate.
