Panel with interlocking edge strip - in which strip is screwed to base and covered by joint

摘要

The covering is made up of a central portion (1) which is flat and carries a number of sections around the edges. One side of the edge has a perpendicular face (8) connected to a lower strip (2). This is connected to the central portion by a fin (7). Fixing screws are located in the strip. The opposite edge is such that its flat web (3) hooks under a rib (4) to hide the screws and form a rigid panel. The space between the panels may be filled with insulating material.
