Improvements relating to panel coupling assemblies

摘要

Two generalize co-planar panels (4) are supported almost edge-to-edge by an intermediate beam (1). A coupling member (2) is captive to the beam (1) by interengaging longitudinal formations (6, 11) and provides an interlocking engagement (12,18) for the edges of the panels (4). Opposite the coupling member (2) the beam (1) is proud of the panels (4) and receives and retains a cap (3) which seals against the panels (4). An assembly for attaching such beams and panels to a wall (30) to project therefrom is described.
