Clamp for shoring and scaffolding frames

A clamp arrangement for connecting elongate rigid structural members comprising two clamps which are capable of being interconnected for either rotation between the two clamps or for positioning of the clamps in at least one predetermined fixed relative position, each clamp having a clamp body which is releasably closeable to surround and clamp a respective structural member, said clamps in the area of their interconnection having opposing portions which have a distinct relative orientation for each said predetermined fixed relative position for said clamps, and means for engaging said opposing portions when they are in each said distinct relative orientation to lock said portions and thereby provide the corresponding fixed relative positions for said clamps.

A clamp arrangement for use with scaffolding and shoring frames comprising at least two clamps, each clamp comprising two clamp jaws pivotally connected together about a hinge point so as to hinge from an open to a closed position for clamping a structural member used in assembling scaffolding and shoring frames, adjacent clamp jaws of said at least two clamps being interconnected for rotation relative to one another about an axis common to all clamp jaws of said arrangement, each clamp jaw having on its exterior between its hinge point and its free end a shoulder arrangement means which is symmetrical about said axis and which cooperates with similar shoulder means arrangement on an adjacent clamp jaw for determining when aligned at least one fixed relative position of adjacent clamps and means for cooperating with and engaging aligned adjacent shoulder means to secure them and thereby provide the corresponding fixed relative position for adjacent clamps.
