ROOFING TILE AND METHOD FOR ROOF COATING FORMING Russian patent published in 2005 - IPC

FIELD: building, particularly roofing tile defining rectangle in plane view.

SUBSTANCE: tile has longitudinal edge formed as longitudinally directed extension with arch-shaped outer surface defined in plane. The arch-shaped surface has orifice formed from overlapping transversal edge side and has longitudinal groove in area of adjunction thereof with flat surface of plate. Another longitudinal tile edge is shaped as semi-cylinder with inner surface mating outer surface of the first longitudinal edge. The inner surface of the semi-cylinder has longitudinal extensions mating the groove of the first longitudinal edge. Plate area located near edge to be overlapped has transversal slot formed on outer plate side. Back plate side has transversal extension located on overlapping edge and mating the slot. Outer side of plate area located near overlapping edge has longitudinal tubular extension arranged at center between outer sides of longitudinal edges thereof. Inner surface of tubular extension mates outer surface of the second longitudinal edge. Back side of plate area located at overlapping edge under the first long edge has extension spaced apart from overlapping edge.

EFFECT: increased reliability and air-tightness of the plate.
