Abstract:
1. A screening apparatus comprising: a plurality of spaced apart, substantially parallel elongate beams; a plurality of screen panels mounted to the beams to form a broad screening surface, each of the panels being generally square or rectangular to define four side edges and the panels being mounted adjacent to each other so that facing side edges of adjacent panels are in close facing relationship, each panel being mounted to a pair of beams along opposite side edges to bridge between two adjacent beams; elongate fixing members for mounting the panels to the beams, wherein the elongate fixing members extend in the longitudinal direction of the beams, are fixed to an upwardly facing edge of the beams and engage opposite side edges of the panels, the elongate fixing members including a pair of projections that extend into openings provided in the edge of the beams, each projection being engaged by a locking clip to lock the projection against release from the opening; the openings into which the projections extend being of a greater diameter than the outside diameter of the projections, so that the projections are a loose fit within the openings to allow movement of the fixing members and the screen panels before the projections are engaged by a locking click to lock the projection against release from the opening, the openings being provided by rings fitted into the slots formed in the edge of the beams and the rings being defined by a wall having a locking opening through which the locking clip extends for engagement with a projection.
