Definitions

  • the invention relates to a roofing arrangement for roofing over a predefinable area, in particular for forecourts, winter gardens, pergolas or house entrances according to the preamble of claim 1.
  • the invention is therefore based on the object of providing a generic roofing arrangement with a relatively simple alignment option for the roof elements to be fastened thereon, and a considerable reduction in the assembly effort with flexible adaptation options should also be possible.
  • a preferred embodiment of the arrangement according to the invention provides that base girders are provided which have a length which corresponds to the edge length of a lattice field, wherein at least one base girder and a crossbeam running at right angles meet in each lattice corner point.
  • double base beams are provided which overlap two grid fields and which have a notch at the upper edge in their central region, for an intersection or for a T-shaped connection of a cross beam extending transversely to the base beam.
  • base supports and double base supports further adapts to individually desired dimensions. It has been shown that a horizontal, self-supporting, lattice-like support structure can be created with a grid dimension of 300 mm, and that from completely prefabricated components, which can be adapted to practically all dimensional requirements.
  • a particularly advantageous possibility for producing the notch results from the fact that the steel sheet profile for producing the notch has a keyway serving as a predetermined breaking line or an elongated hole.
  • the V-shaped gutter proves to be very well suited for removing rainwater and is created according to an advantageous further development of the subject matter of the invention that the angled edge region to form the V-shaped gutter is angled by an angle of approximately 45 degrees with respect to a vertically arranged main carrier surface is.
  • Both the bending stiffness and the buckling strength of the beams are influenced particularly favorably in that the steel sheet profile of the beam in its lower region has an angled region to one side, which is angled in the same direction as the upper edge region, and that the lower edge of the angled area is bent in the opposite direction to the said bend in such a way that a bulge and an essentially perpendicular to the main beam lower flange is formed, the edge of which is arranged in the plane defined by the main beam surface.
  • the steel sheet profiles are cold-formed profile parts.
  • the light metal connecting plates arranged between the steel sheet profiles can of course also be designed as extruded profiles or as cast parts without leaving the scope of the invention.
  • the material information set out in the present description also serves primarily to illustrate the subject matter of the invention, and other materials with sufficient strength can also be used within the scope of the invention.
  • the steel sheet profile has a total height of approximately 180 mm, of which the upper angled edge region is approximately 30 mm, the main carrier surface is approximately 100 mm and the lower angled region is approximately Take 50 mm.

  • the elongated holes fulfill an advantageous double function because, on the one hand, they serve for holding clips for roof skin elements to engage in these elongated holes, while the further function of these elongated holes can be seen in the fact that they greatly simplify the release of the double base beams.
  • To produce a notch it is only necessary to make an incision transversely from above at the two ends of an elongated hole from the edge of the carrier to the elongated hole in order to produce the desired notch.
  • the steel sheet profile on the main carrier surface and on the lower flange at a distance from one another, which corresponds to a predeterminable fraction of the grid dimension, have rows of punchings.
  • An advantageous embodiment further provides that two rows of punchings are provided on the main carrier surface, which mark the bores for the connecting screws and the cutting lengths for the carriers.
  • the markings serve on the one hand as a unit of measurement for cutting the beams to length and on the other hand for creating the drilling pattern without a drilling template for the beam connections.
  • the keyways provided in the longitudinal direction of the carriers in an alternative embodiment are used to form the notches. This is because a portion of the carrier can simply be broken out after sawing in the direction transverse to the keyway from the edge of the carrier to the keyway.
  • the connecting plates have the shape of an inverted "T" in cross-section, the transverse legs of which are arranged within the bulge and are screwed to the horizontal lower flange.

  • Such an arrangement can preferably be further developed in that the eccentric cam is polygonal in cross section, two mutually parallel surfaces being provided at the same distance from the fulcrum.

  • a permanently elastic sealing tape is arranged between the edges of roof skin elements projecting into the V-shaped channel.
  • the assembly is considerably facilitated in that a double-sided adhesive tape is arranged along the edges of the roof skin elements, which protrude into the V-shaped channel, and is covered with protective tape that can be removed for assembly.
  • edges of the dome-shaped roof skin elements protruding into the V-shaped channel are held by elastic retaining clips which engage the carriers.
  • these retaining clips are characterized in that the retaining clips each have V-shaped cantilevers in their upper region which extend over the edges of the roof skin elements and have hooks engaging in openings in the carriers in their lower region.
  • the arrangement is advantageously made such that the hooks engage in elongated holes which are arranged in the horizontal direction in the main carrier surfaces.
