Erection anchor for concrete panel

An erection anchor for use in a concrete panel having substantially parallel major surfaces and a recess in an end of the concrete panel, the erection anchor comprising:

• a forged unitary body comprising
• a substantially cylindrical shank with
• one end adapted to be embedable in the end of the concrete panel, and
• an opposite end adapted to extend into the recess in the end of the concrete panel;
• a substantially cylindrical foot integrally formed with the one end of the shank and adapted to be embedable in the concrete panel, the foot having a diameter greater than a diameter of the cylindrical shaft;
• a shackle-engageable, planar head integrally formed with the opposite end of the shank and adapted to be disposed in the recess in the end of the concrete panel, the planar head having first and second substantially parallel planar surfaces extending between first and second lateral edges of the planar head;
• first and second bosses integrally formed with the planar head and extending outward from, and substantially perpendicular to, the first and second planar surfaces, respectively, the first and second bosses having lengths substantially parallel to the first lateral edge and the first and second bosses forming respective first and second pluralities of bearing surfaces adapted to interlock the erection anchor with the concrete panel;
• and
• third and fourth bosses integrally formed with the planar head and extending outward from, and substantially perpendicular to, the first and second planar surfaces, respectively, the first and second bosses having lengths substantially parallel to the second lateral edge and the third and fourth bosses forming respective third and fourth pluralities of bearing surfaces adapted to interlock the erection anchor with the concrete panel.

A structural member comprising:

• a concrete panel comprising
• two opposing major surfaces extending over a length and width of the concrete panel,
• an end surface extending between the opposing major surfaces and defining an end of the concrete panel,
• a recess disposed in the end surface;
• and
• an erection anchor comprising
• a forged unitary body comprising
• a substantially cylindrical shank with
• one end embedded in the end of the concrete panel, and
• an opposite end extending into the recess in the end of the concrete panel;
• a substantially cylindrical foot integrally formed with the one end of the shank and embedded in the end of the concrete panel, the foot having a diameter greater than a diameter of the cylindrical shaft;
• a shackle-engageable, planar head integrally formed with the opposite end of the shank and disposed in the recess in the end of the concrete panel, the planar head having first and second opposed planar surfaces;
• and
• a boss integrally formed with the planar head and extending outward from the first planar surface, the first boss forming a first plurality of bearing surfaces adapted to interlock the erection anchor with the concrete panel.

An erection anchor for use in a concrete panel having substantially parallel major surfaces and a recess in an end of the concrete panel, the concrete panel being lifted by a lifting device having a shackle, the erection anchor comprising:

• a forged unitary body comprising
• a substantially cylindrical shank with
• one end adapted to be embedable in the end of the concrete panel, and
• an opposite end adapted to extend into the recess in the end of the concrete panel;
• a substantially cylindrical foot integrally formed with the one end of the shank and adapted to be embedable in the concrete panel, the foot having a diameter greater than a diameter of the cylindrical shaft;
• a shackle-engageable, planar head integrally formed with the opposite end of the shank, the planar head comprising
• boss integrally formed with the planar head and extending outward from a major surface of the planar head, the boss forming a first plurality of bearing surfaces adapted to interlock the erection anchor with the concrete panel, and
• an outer end with a pair of projections, each projection extending from the outer end of the planar head adjacent a different one of the lateral edges, the pair of projections forming side walls of a cutout having a configuration adapted to receive an end of the shackle and hold the shackle therein during a process of lifting the concrete panel.
