Each plate (2) lies in part on a support frame whose one side has a sealing profile reaching partly up to the top of the plate along one plate edge. The frame has extensions in the form of profile plugs for mechanical connection to the adjoining plate. The sealing profile is fitted onto frame extensions in two adjoining frame legs. The frame is in one piece or of extruded profiles and can be made of re-cycled material. The four frame legs form the support (5) for the plate, the frame legs cammed on one pair and holed in the other pair of legs to make up the extensions used to connect adjoining plates. The plates are soundproofed (12) underneath by material bonded to the plate. |
