Concrete slab anchor
A concrete anchor has a body with cam surfaces. Each of the cam surfaces curves outward from a first edge to a second edge. The cam surfaces have a circumscribed outer diameter that increases in a downward direction. Jaws are retained around the body, each of the jaws having an inner side in engagement with one of the cam surfaces. Each of the jaws decreases in radial thickness in a downward direction. Cam ratchet teeth on each of the cam surfaces engage jaw ratchet teeth on the inner side of each of the jaws. The jaw ratchet teeth ratchet over the cam ratchet teeth as the body rotates in a first direction to move the jaws from a contracted position to an expanded position. The engagement of the cam and jaw ratchet teeth prevent rotation of the body relative to the jaws in the opposite direction.
