ABSTRACT:
A plastic insert for concrete structures includes a barrel for receiving a threaded fastener. According to one embodiment, the insert includes a housing at a distal end receiving an internally threaded member for engaging the threaded fastener. The insert includes bar-engaging members at the distal end for contacting concrete-reinforcing bars of the concrete structure. The insert also includes a bar-engaging member at the proximal end including a retainer defining a substantially semi-circular channel for receipt of a U-shaped portion of a bar. According to another embodiment, the insert includes a base at the distal end extending outwardly from the barrel to define an anchoring surface oriented perpendicular to the barrel axis. Longitudinal ribs on the barrel include segments arranged in series. Each segment of the rib extends radially to a distance that decreases with each succeeding segment such that each segment defines a bearing surface.
