  • Patent number: 9340979
    Abstract: A roof covering element (a tile-like sheet) equipped with embossments according to the present invention characterizes in that the surface of the lower edge (2) of the roof covering element (1) has at least one embossment (3) done downwards and inwards in relation to the roof covering element (1) with an assembling hole (4) prepared centrally. A bottom of that embossment (3) is at zero or acute angle with the surface of the lower edge (2). The surface of the upper edge (5) of the roof covering element (1) has at least one embossment (6) done downwards and inwards in relation to the covering element (1) with an assembling hole (7) prepared centrally. A bottom of that embossment (6), preferably of circular shape, is at zero or acute angle with the surface of the upper edge (5).

  • Publication number: 20150275519
    Abstract: Method of a roof covering with roof covering elements (tile-like sheets), in which the lower transversal step has got fixing sunken embossing well-fitting to the bend of the upper transversal step of an adjacent roof covering element placed over the former one, performed according to fixed procedure, preferably with use of prefabricated assembling embossments and holes, exploiting embossments at a corner of the roof covering element and an element fixed to a roof with mounting device at one end and its the other end clamps an edge of the roof covering element to the roofing characterised in that the left edge (1.1) of an initial sheet (1) stabilized by fastening with at least one screw to a roof batten (3) is covered by the right edge (4.1) of the second sheet (4). The sheets are mounted by a screw placed through the right lower assembling hole (4.2) of the second sheet (4) and the left lower assembling hole (1.2) of the initial sheet (1).
