<p>The constructional component comprises a supporting inner body and a casing forming the side and rear walls, and bent over at the edges. To allow plastic-coated sheet metal panels to be used for the casing, the bent-over portions fit round the body, and the panels are locked in place by concealed devices. The inner body can comprise a frame of profiled girders, the vertical supporting columns having protruding flanges, round which the bent-over portions of the panels fit. A U-section plastic-coated component fits over the flanges of adjacent bodies to secure them together.</p> |
