An anchor particularly adapted to be embedded into a concrete construction for suspension of a ceiling panel, duct or the like, includes a base which receives inserts that have an axial threaded bore. The base is open at its lower end and can receive a threaded rod by virtue of ratcheting inserts received within the base. The inserts and base are particularly shaped to prevent jam and ease of insertion of the rod in the anchor. The anchor also has a head flange that sits above a plurality of fasteners secured to the anchor which is used to simultaneously drive the fasteners into a form for the concrete member. The fasteners are connected to the anchor extending in generally parallel and spaced relation to the anchor. The fasteners can be held by a support or sleeve-like holder which surrounds at least a portion of the base of the anchor or they can be attached to the base of the anchor. The fasteners project downwardly through the bottom of the anchor for driving into the form board.

1. A connection between a rod, an anchor, and a first structural member, the connection comprising: a. the first structural member;b. the rod, having a thread with a thread angle; andc. the anchor, connecting the first structural member to the rod, the anchor including a housing, the housing having a bottom and a top, and the anchor having a longitudinal central axis extending through the bottom and the top of the housing, the housing having an insert receiving bore that opens through the bottom of the housing, the insert receiving bore having a narrowing lower portion closer to the bottom than the top of the housing; and wherein a plurality of inserts are disposed in the insert receiving bore and contained securely within the housing, each of the inserts has a base bore interfacing surface that interfaces with the narrowing lower portion of the insert receiving bore of the housing, wherein each insert has a concave inner surface and the plurality of concave inner surfaces form a generally tubular interior rod receiving bore that receives a portion of the rod, and the inserts are sized with respect to the housing such that when the rod is received in the interior rod receiving bore and engages the inserts and moves toward the bottom of the housing, the inserts will be pulled toward the bottom of the housing, and the narrowing in the lower portion of the insert receiving bore causes a constriction of the inserts about the rod forcing them to grasp and hold the rod, the lower portion of the insert receiving bore of the housing has a base-bore first sliding surface disposed at an angle to the longitudinal, central axis of the anchor and when the rod is inserted into the interior rod receiving bore and moves toward the top of the housing, the inserts can be moved away from each other and from the longitudinal, central axis of the housing, allowing the rod to be inserted farther into the housing and towards the top of the housing; and whereind. the first sliding surface of the housing is set at the same angle as the thread angle of the rod. 2. The connection of claim 1, wherein: the interior rod receiving bore is formed with multiple diameters such that anchors of different diameters can be received by the inserts. 3. The connection of claim 1 wherein: the first structural member is a hardened concrete member, and the anchor is embedded the hardened concrete member. 4. A method of forming the connection of claim 1 comprising the steps of: a. embedding the anchor in the first structural member; andb. inserting the rod into the interior rod receiving bore of the anchor. 5. A connection between a rod, an anchor, and a first structural member, the connection comprising: a. the first structural member;b. the rod; andc. the anchor, connecting the first structural member to the rod, the anchor including a housing, the housing having a bottom and a top, and the anchor having a longitudinal central axis extending through the bottom and the top of the housing, the housing having an insert receiving bore that opens through the bottom of the housing, the insert receiving bore having a narrowing lower portion closer to the bottom than the top of the housing; and wherein a plurality of inserts are disposed in the insert receiving bore and contained securely within the housing, each of the inserts has a base bore interfacing surface that interfaces with the narrowing lower portion of the insert receiving bore of the housing, wherein each insert has a concave inner surface and the plurality of concave inner surfaces form a generally tubular interior rod receiving bore that receives a portion of the rod, and the inserts are sized with respect to the housing such that when the rod is received in the interior rod receiving bore and engages the inserts and moves toward the bottom of the housing, the inserts will be pulled toward the bottom of the housing, and the narrowing in the lower portion of the insert receiving bore causes a constriction of the inserts about the rod forcing them to grasp and hold the rod, the lower portion of the insert receiving bore of the housing has a base-bore first sliding surface disposed at an angle to the longitudinal, central axis of the anchor, and above the base first sliding surface is a middle housing wall, and when the rod is inserted into the interior rod receiving bore and moves toward the top of the housing, the inserts can be moved away from each other and from the longitudinal, central axis of the housing, allowing the rod to be inserted farther into the housing and towards the top of the housing;d. the inserts are formed with lower portions where the shape of the base bore interfacing surface causes the insert to taper to a bottom edge of the insert; ande. the middle housing wall has a diameter large enough to contain the lower portions of the inserts when there is a constriction of the inserts about the rod and the inserts grasp and hold the rod;f. the base-bore first sliding surface is frusto-conical in shape; andg. the base bore interfacing surface is frusto-spherical where the base bore interfacing surface makes contact with the base-bore first sliding surface. 6. The connection of claim 1, wherein: the interior rod receiving bore is formed with multiple diameters such that anchors of different diameters can be received by the inserts. 7. The connection of claim 1 wherein: the first structural member is a hardened concrete member, and the anchor is embedded the hardened concrete member. 8. A method of forming the connection of claim 1 comprising the steps of: a. embedding the anchor in the first structural member; andb. inserting the rod into the interior rod receiving bore of the anchor.
