Abstract: An undercut anchor having an at least partially threaded rod portion having an outer thread diameter DROD. The anchor having an expansion feature coupled to the rod portion and an expansion sleeve having an outer diameter DOUTER SLEEVE, an inner diameter DINNER SLEEVE and a wall thickness TSLEEVE. Furthermore, the expansion sleeve has a plurality of circumferentially distributed fingers which are configured to flex outwards when a ramp portion of length LRAMP of each of the respective fingers is forced against the expansion feature during installation of the undercut anchor. The fingers each having a length LFINGER and a distance therebetween of WSLOT.

Abstract: A cast-in-place anchor assembly is disclosed for suspending objects below a metal deck. The assembly includes an anchor body and an anchor support. The anchor body includes a threaded opening. The anchor support includes a central member which, in use, extends from a first upper side of the metal deck to a second lower side of the metal deck. The central member further includes a connector. The central member also includes a biasing portion which cantilevers radially outward. The central member further includes a stopping member sized to be larger than a deck opening. An end of the anchor body is connected to a connector to conceal the threaded opening from poured concrete. The stop member flexes to pass through the opening in the metal deck and the stop member and the biasing member flexingly bias the anchor support into position relative to the metal decking.
