Two injection molded u-profiles are positioned parallel at a distance from each other and joined with bridges (5, 6) in the shape of integrated semi-circular elements (5). Each of the bridges (5) is provided with a central hole for the insertion of a T-shaped element protruding from the upper surface of the basic construction, which is rotated into a locking position after insertion. Both ends (2) of the slat are fitted with angle elements (10, 11, 12). The vertical section (11) of the element can be inserted into a matching gap at the base and secured with screws.
