FIELD: building, particularly roof construction. ^ SUBSTANCE: multi-purpose tile defines figure with two crescent depressions in upper invisible part in plan view. The upper invisible part is closed with upper row tiles. Outer wedge-like rib defines visible tile surface and is shaped as tangents to figures, for instance to oval or circle. This provides varying outer tile shape. Invisible tile part is the same for all possible outer tile surfaces defined by tangents to generatrices of equidimensional figures. All tiles have five fastening orifices. One orifice is formed in outer wedge-like rib in axis of symmetry and adapted to secure visible tile part by fixing clamp engagement. Remainder orifices are directed in tile figures so that each fixing screw passes through two adjacent tiles to provide self-alignment thereof. ^ EFFECT: increased wind resistance, prevention of capillary moisture penetration into gapless contact areas between inner and outer wedge-like ribs. ^ 15 dwg |
