Abstract: A wedge anchor comprising a barrel having a wedge receiving face opposite a rod receiving face, a passage extending therethrough between the wedge receiving face and the rod receiving face, the passage narrowing toward the rod receiving face and having an axial cross-sectional profile defining a convex arc; and, a plurality of wedges insertable into the passage, each of the wedges having a respective inner wedge face for defining a rod receiving passage for receiving a rod and an outer wedge face, opposite the inner wedge face, in axial cross-section having a profile complementary to the convex arc.

Abstract: A wedge anchor for holding a rod under a load is provided. The wedge anchor comprises a barrel comprising a wedge receiving face opposite a rod receiving face. A barrel passage extends therethrough between the wedge receiving face and the rod receiving face. The passage narrows toward the rod receiving face and has an axial cross-sectional profile defining a convex arc having a barrel centre of radius of curvature. The wedge anchor also comprises a plurality of wedges that are insertable into the passage. Each of the wedges comprises an inner wedge face for defining a rod receiving passage for receiving the rod and an outer wedge face, opposite the inner wedge face, in axial cross section having a profile complementary to the convex arc. The outer wedge face has a wedge-face centre of radius of curvature, which is offset relative to the barrel centre of radius of curvature.
