<p>The sections (1) have a slot (2) corresponding to one or more walls and one or more blocks (3) which are slid in the slot. The section side walls have two different thickness layers which define, in the internal part, two channels of different widths (4,5). The blocks are inserted in the widest channel (4) and the other channel can be used for electrical wiring. The blocks have a pair of holes (6,6') for fixing complementary structural components. These components may form the chassis of a shelf (7) or panels (8) having holes (9,10).</p> |
