Definitions

  • the invention relates to a roof covering element, in particular a concrete roof tile, with a hanging ledge, foot rib and, if appropriate, transverse ribs arranged therebetween, the roof covering element optionally having an S or wave-shaped cross section having ribs, preferably three ribs, in its longitudinal edge region covered by a similarly formed adjacent roof covering element in the use position , on which the overlapping longitudinal edge area of the adjacent roof covering element rests with contact surfaces, the rib apex or the upward-facing end faces of the adjacent ribs progressively taking a lower level from the outside inwards in the position of use, and the contact surfaces assigned to the ribs progressing from the outside inwards are located at a higher level, the higher-lying rib possibly passing over a curve into the lower-lying rib, w o a distance is provided between the side surface of the roof covering element or the side surface of the outermost, highest rib and a boundary surface of the overlapping longitudinal edge region of the adjacent roof covering element opposite this side surface, and
  • roof tiles with folds are known that prevent mutual movement of the installed roof tiles.
  • roof tiles There are provided in these known roof tiles in the verfelz ⁇ hqe ⁇ or longitudinal edges upward and downward ribs and associated supports that engage with each other.
  • roof tiles which are movable relative to each other or which are adaptable when laying different roof dimensions and have ribs engaging in grooves in the overlap area.
  • the aim of the invention is to design such roof covering elements in such a way that the roof covering elements do not spread out against one another when covering and that the gap between roof elements lying on top of one another in the fold area is kept as small as possible, but at the same time inaccuracies during laying can be compensated for.
  • a roof covering element of the type mentioned at the outset in that the support surfaces which are arranged in a step-like manner in the overlapping longitudinal edge region are connected via inclined intermediate surfaces which are preferably adapted to the inclination of the rib flanks, and that in the case of covered or interlocking longitudinal edge regions between the rib flanks and the intermediate surfaces connecting the support surfaces are designed with a space for a lateral relative movement of the ribs with respect to the support surfaces.
  • the distance between the intermediate surface that connects the highest-lying contact surface to the closest-highest contact surface and the boundary surface is greater than the width of the outermost rib or its base, which may be rounded in the end region, and if the distance between the boundary surface and the intermediate surface connecting the highest lying contact surface with the next lower supporting surface is greater than the distance between the side surface facing this intermediate surface of the rib following the outermost rib, possibly rounded in the end region, and the side surface of the roof covering element or the outermost rib. It is advantageous if the highest bearing surface is flat
  • the contact surfaces in the case of three contact surfaces in the overlapping longitudinal edge region in particular the central contact surface, are or are flat, or that the contact surfaces have a convex curvature or, in the case of concave curvature, a smaller curvature than the curvature in the apex of the associated one Have rib.
  • the width or the base width of the ribs is smaller than the width of the bearing surfaces assigned to them. It can also be provided that the width of the inner bearing surfaces corresponds approximately to the base width of the inner ribs plus half or all of the rounding width of the fillets adjoining the inner ribs.
  • the basic width of the ribs is measured in the area of the rib in which the rib rounding or the rib flanks ends (n) or where the fillets between the ribs connect to the rib flanks.
  • all the support surfaces in the overlapping longitudinal edge region are either flat or curved surfaces and, if appropriate, have the same shape as one another.
  • Ribs 4, 5 and 6 are formed in the upward fold or the covered longitudinal edge region 7, the rib 6 having a flat or flattened bearing surface. Grooves or fillets 10 are provided between the ribs 4, 5 and 6. The ribs 4, 5, 6 are arranged in steps to prevent water from penetrating or to divert it into the grooves 10.
  • support surfaces 1, 2 and 3 are formed, which are connected to one another by bevels or intermediate surfaces 12, 12a.
  • the contact surfaces 1, 2 and 3 are arranged in a step-like manner, the top contact surface 1 being arranged in the region of the inside of the shaft apex.
  • the overlapping longitudinal edge region 8 is laterally delimited by a boundary surface 13 formed on the roof covering element 9, around the side surface 14 of the covered one Longitudinal area in a shift in the drawing to the left after a certain space to offer a stop.
  • the contact surfaces 1, 2, 3 in the overlapping longitudinal edge region 8 are flat, since this ensures a linear contact between the ribs 4, 5 and the contact surfaces 1, 2, which provides good resistance to the ingress of air and water becomes. Furthermore, it is expedient if the lowermost support surface 3 and the lowermost rib 6 have flat surfaces, since an optimal seal against incoming or blown-in water is thereby achieved.
  • the distances between the boundary surface 13 and the intermediate surfaces 12, 12a and the width of the ribs 4, 5, 6 determine the lateral play; in particular, the base width or the slope of the ribs 4, 5, 6 must also be taken into account, it being advantageous if the intermediate surfaces 12, 12a and the slope of the edges 4a, 5a of the ribs run parallel to one another.
  • the contact surfaces 1, 2 and 3 are convex or concave. If in this case the longitudinal edge areas 7, 8 are shifted relative to one another, the overlapping longitudinal edge area 8 is raised or lowered, which may be desirable in order to compensate for height differences of the roof covering elements. It is useful if all of the contact surfaces 1, 2, 3 have the same shape.
  • the rib 6 ends laterally in a bend 11 in which its flat bearing surface merges into the outer surface of the roofing element 9.
  • the kink is chosen such that the outside of the overlapping longitudinal edge region 8 merges into the outside of the roofing element in front of the kink 11 and the corrugation of the roof tile is not interrupted, or is interrupted only insignificantly.
  • the cross-section of the roof tiles can be S-shaped or white, or straight and curved sections or exclusively straight sections, or can be straight.
  • Three ribs and contact surfaces are preferably provided; however, more or fewer ribs and contact surfaces can also be provided.
