Patent ID: 8898964

Claim:
A lift anchor assembly for precast Portland cement concrete shapes, the lift anchor assembly comprising: a plate-like lift anchor characterized by a lift end and an embedment end, and defining a longitudinal axis, the lift end including a bilaterally symmetrical lift plate characterized by a through-opening, the embedment end including a bilaterally symmetrical embedment portion spaced away from the lift end and coupled with the lift plate, and a pair of elongate legs parallel to the longitudinal axis, each leg coupled with the embedment portion, and with the lift plate; a recess insert characterized by a pair of concave insert shells coupled together by a pivotable coupling, each insert shell including a curved wall having a tabbed end, each tabbed end comprising a tab reinforcer including a shear bar retainer and a projection, the projections joinable by rotation of the insert shells together about the pivotable coupling; and an elongate rod-like shear bar characterized by a U-shaped bend comprising a pair of spaced-apart parallel bight legs; wherein the insert shells are positionable on either side of the lift end and rotatable about the pivotable coupling to a closed configuration so that the projections extend into, and are joined in, the through-opening to fixedly retain the recess insert in a predetermined position over the lift end; wherein the shear bar is fixedly coupleable with the recess insert by slidably engaging the bight legs with the shear bar retainers; wherein the recess insert is fixedly coupleable with the lift anchor by the insertion of the projections into the through-opening; wherein separation of the projections from the through-opening and separation of the insert shells from the lift anchor are controllable by the coupling of the shear bar to the shear bar retainers; wherein movement of the shear bar relative to the recess insert and the lift anchor is controllable by the engagement of the shear bar with the shear bar retainers; and wherein the recess insert, the lift anchor, and the shear bar are interlockable into a lift anchor assembly resistant to movement during preparations for and placement of precast Portland cement concrete.
