ABSTRACT:
A joint bridging arrangement comprises a bridging unit having a central portion, side parts, and anchoring units adjoining the longitudinal sides of the side parts. The side parts are pivotably connected to the central portion for movement about a pivot axis parallel to the longitudinal axis of the bridging arrangement. Cleats or legs of the side part and anchoring unit are interengaged and relatively slidable at an acute angle relative to the upper side of the center part. The upper-most surface of the bridging unit includes a portion having a wedge shaped cross section corresponding to the acute angle so that the transition from the bridging to the anchoring units, and hence to the structural parts bridged by the joint is essentially stepless.
