Abstract
A blocking-up wedge of the kind used in pairs for the levelling of joists and the like consisting of a prismatic-shaped body, the terminal surfaces of which being triangles, and at least one wedge surface being provided with a relatively great friction profiled formation in such a direction that the mutual displacement of the pair of wedges reducing the distance between the parallel supporting surfaces of the pair of wedges is principally prevented and lateral shifting of the wedges is controlled or prevented.
