Roof or wall covering and mounting member for a gutter bracket

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). |

DETAILED DESCRIPTION According to the present invention a roof or wall covering of the kind referred to above is characterized in that the cross sectional profile of the longitudinal edge zones of the concave strips is S-shaped and comprises an inner portion adjoining the central section of the strip and curved towards the concave face of said central section, said inner portion having a first radius of curvature, a median portion curved in the opposite direction and having a second, smaller radius of curvature, and an outer portion having a third radius of curvature larger than the first radius of curvature; that the fastening members are generally U-shaped brackets, each having a web portion secured to the substructure and two lateral flanges, the free edge zones of which are profiled complementary to the edge zones of the concave strips and are retracted inwardly towards the centre line of the U at the transition to the adjoining portion of the respective lateral flange; that the edge zones of the convex strips are profiled complementary to the median and outer portions of the edge zones of the concave strips; and that the width of the convex strips is smaller than the total outer width of a fastening bracket plus the edge zones of two concave strips inserted in the bracket fom opposite sides thereof.
The invention results in several advantages, including a highly efficient securing of the strips to the substructure due to the fact that the convex strips embrace a substantial portion of the fastening brackets and the edge zones of the intermediate concave strips and hold the latter securely by means of elastic forces determined by their being deformed from the unloaded state to the mounted or assembled position.
Forces acting on the concave strips from the outside of the covering and directed towards the substructure will tend to deform the convex strips further whereby the reaction forces exerted by these strips increase.
Suction forces acting on the outer side of the covering are taken up by the brackets as a result of the interengagement between the edge zones of the brackets and the S-shaped edge zones of the concave strips
