<p>Superficial wall cladding panels made of (reinforced) poly-ester resin or similar material are supported by lugs or ribs protruding from the reverse face of the panel which are inserted between the turns of helical springs mounted at intervals in the supporting wall or on the flanks of a trough-section ancillary profile mounted on the wall. Compared with use of dowel pins engaging socket holes at specific intervals, the ribs or lugs can slide relative to the springs to allow adjacent panels to be supported at different levels to compensate for localised variations in the planarity of adjacent floors or ceilings. The springs may be located by mechanical clips or by welding etc. Pref. the support ribs are adjacent to peripheral lips on the internal border of each panel, so that the channel profile carrying the springs also serves as an internal mask for the joint between adjacent panels.</p> |
