<p>The covering is composed of alternate broader lower strips (1) and narrower upper strips (2), the outer surfaces of which strips are concave and convex, respectively. The strips are resiliently connected to one another and to fastening brackets (3) by means of interengaging longitudinal edge zones (6, 11, 14) on the strips and the brackets. The profile of each edge zone (6) of the lower strips (1) is S-shaped and includes a convex portion (7) engaging with a concave surface on an edge zone (14) of the bracket, and a portion (8, 9, 8', 10) which embraces the edge zone of the bracket. Each edge zone (11) of the upper strips (2) embraces the outermost portion (9, 8', 10) of an edge zone of a lower strip. A gutter (20) bracket (21) can be clamped between an upper strip (2) and the adjoining lower strips (1) by means of a mounting member (22) comprising a main part (23, 24) which, together with the gutter bracket, is urged downwardly into the edge zones of the lower strips by means of a threaded bolt (28), and a clamp (26) which is urged upwardly against the upper strip (2).</p> |
