Precast concrete lift anchor assembly
A lift anchor assembly for a precast Portland cement concrete shape comprises a recess insert, a bilaterally symmetrical lift anchor, and an elongate triangular space. The recess insert is characterized by a longitudinal plane of symmetry, and is separable along a break line extending perpendicular to the longitudinal plane of symmetry into a pair of quadrant-shaped bodies, each characterized with a planar obverse wall. The bilaterally symmetrical lift anchor is characterized by a longitudinal axis of symmetry coextensive with the longitudinal plane of symmetry, and is immovably sandwiched between the quadrant-shaped bodies. The elongate triangular space is formed beneath the break line and extends orthogonal to the longitudinal plane of symmetry. A force applied to the break line toward the elongate triangular space will urge the quadrant-shaped bodies into rotation out of the Portland cement concrete.
