<p>A circulation area (1) which is formed from plate-like covering elements (3a, 3b) which are laid so as to adjoin one another. In the mutually facing edges (4a, 4b) of covering elements (3a, 3b) which are arranged adjacently to one another, recesses (7a, 7b, 7c, 7d) are provided which penetrate parallel to the surface extent of the covering elements from said edges (4a, 4b) into the covering elements. Recesses (7a, 7b, 7c, 7d) which lie opposite one another are aligned with one another. Aligning bars are mounted movably in each case in one of two recesses which are aligned with one another, and can be moved by means of an adjusting shaft (8a, 8b) partially into the other of the two recesses which are aligned with one another, with the result that they are then in engagement with both recesses (7a, 7b, 7c, 7d) which are aligned with one another, and bridge the separation (9) which exists between adjacent covering elements (3a, 3b).</p> |
