| (54) | System for covering different types of surfaces, especially for building use |
| (57) System for covering different types of surfaces, especially for building use, consisting
essentially of a fundamental component (1) of quadrilateral shape made out of a piece
of sheet metal cut to the desired shape in which two opposing pairs of mutually adjacent
sides are bent in opposite directions to form corresponding opposing bent edges (11-12).
When laid, those edges (11) which are bent towards the outer surface of the component
(1) are uppermost and each component (1) is fixed to the underlying structure by a
single strap (7) bent at one end which hooks into the inner vertex of these upper
bent edges (11). The individual components (1) are interconnectable by a simple hook
action in which said bent edges (11-12) are inserted into each other. Other complementary
components for completing the sides of the covering can be derived from the fundamental
component (1), and an additional ridge component (6) can be provided for use in the
case of roof coverings. |
