Abstract

The present invention relates to an anchor (10) for post tensioned concrete reinforcement comprising a base member (14), a rear tubular portion (22), a front tubular portion (24), reinforcing ribs (42), and four mounting holes (56). The square plate shaped base member (14) facilitates uniform distribution of load on the concrete surface. The base member (14) has rounded corners to minimize stress concentration. The rear tubular portion (22) and front tubular portion (24) protrude from the base member (14) in opposite directions forming a through tubular section (30). The rear tubular portion (22) receives the tendon (34) to extend into the inner cavity of the tubular section (30). The front tubular portion (24) has a tapered inner cavity that receives a conventional tapered wedge (32). The tapered wedge (32) is tightened, which forces it against the sides of the tapered inner cavity, clamping the tendon in place. The reinforcing ribs (42) extend radially outward from the exterior of the front tubular section (24) on the front surface (16) of the base member (14). The anchor (10) is light weight, cost effective and easy to manufacture and handle on account of increased strength and less material requirement. The mounting holes (56) allow the anchor (10) to be secured to the concrete surface with nails (58). This arrangement allows the anchor (10) to be oriented in any direction, which provides flexibility in installation.
