Abstract
A clamp head including an arched body having upper and lower faces, and opposing unequal length arms. The body further has a through aperture for a bolt or like threaded fastener extending between the upper and lower faces, the through aperture tapering outwardly through the body in the direction of the lower face. The arms comprise a reaction arm having at its distal end a curved reaction face and a clamping arm having at its distal end a curved clamping face. The curved reaction face has a first edge that is proximal to the reaction face and a second edge that is distal to the reaction face, wherein the radius of curvature of the reaction face increases in the direction of the second edge.

A clamp head comprising an arched body having upper and lower faces, and opposing unequal length arms, the body further having a through aperture for a bolt or like threaded fastener extending between the upper and lower faces, the through aperture tapering outwardly through the body in a direction of the lower face, wherein the arms comprise a reaction arm, the reaction arm having a curved reaction face at a distal end extending across an entire width of the reaction arm and a clamping arm, the clamping arm having a curved clamping face at a distal end, the curved reaction face has a first edge that is proximal to the clamping face and a second edge that is distal to the clamping face, wherein a radius of curvature of the reaction face increases in a direction of the second edge, wherein the upper face of the body is provided with a recess configured to receive an insert, wherein the through aperture extends through the body from a lower region of the recess, wherein the through aperture further intersects the reaction face and the clamping face.
A clamp head comprising an arched body having upper and lower faces, and opposing unequal length arms, the body further having a through aperture for a bolt or like threaded fastener extending between the upper and lower faces, the through aperture tapering outwardly through the body in a direction of the lower face, wherein the arms comprise a reaction arm, the reaction arm having a curved reaction face at a distal end extending across an entire width of the reaction arm and a clamping arm, the clamping arm having a curved clamping face at a distal end, the reaction arm being longer than the clamping arm, the curved reaction face has a first edge that is proximal to the clamping face and a second edge that is distal to the clamping face, wherein a radius of curvature of the reaction face increases in a direction of the second edge, wherein the upper face of the body is provided with a recess configured to receive an insert, wherein the through aperture extends through the body from a lower region of the recess, wherein the through aperture further intersects the reaction face and the clamping face.
The clamp head as claimed in 13, wherein the clamping face of the clamping arm is provided with one or more formations which, in use, frictionally engage a clamping surface against which the clamping face rests.
