An anchor holder for concrete decks comprises a body for being inserted into an opening in a metal deck, the body including an outside vertical wall and an opening for receiving an anchor. The body includes arms normally biased extending outwardly from the vertical wall, the arms being collapsible toward the body when the body is inserted into the opening in the metal deck and expanding outwardly after passing the opening to be disposed below the metal deck. A support is attached to the body, the support to engage a top surface of the metal deck to apply an upward force on the body and keep the collapsible arms engaged against an underside of the metal deck when the body is attached to the metal deck.

The present disclosure describes an anchor device for receiving and securing a shaft thereto. The device includes an outer housing within which a jaw assembly is secured. The outer housing of the device may in turn be secured to or within a support structure such as a building component. Jaw components of the jaw assembly may be threaded. Furthermore, the jaw assembly has at least two configurations. In a first configuration, at least one jaw component is positioned away from a central shaft axis against the biasing force of a biasing member. A removable or reconfigurable holding member or stop member selectively secures the at least one jaw component in its position. In as second configuration, the holding member is reconfigured by the inserted shaft to trigger movement of the at least one jaw component toward the central shaft axis and into contact with the shaft.

Concrete coupling assembly comprises a base holder for being attached to a concrete forming surface, the base holder including a central opening; a coupler having one end disposed within the central opening, the coupler having an axis for being positioned substantially transverse to the forming surface, the coupler having first and second threaded bores through the one end for attachment of a threaded rod; and a separate anchor body threadedly attached to another end of the coupler.

An anchor rod support comprises a support having a floor and legs extending downwardly from the floor with openings between the legs; and the support including threads for attaching thereto an anchor rod.

A concrete anchor assembly includes a housing including a lower opening and a side wall; a flange portion extending from the housing; a ramp surface extending upwardly around the lower opening; a split body disposed over the lower opening, the split body including a bottom surface engaging the ramp surface, the split body including a threaded opening. The housing includes a gap between the split body and the side wall. A compressed spring forces the split body toward a bottom of the ramp surface.
