Definitions

  • the present invention relates to a roofing element according to the preamble of claim 1 and a method for its laying.
  • a roofing element which consists of a plurality of approximately parallel, side by side and one above the other arranged plastic straws, which are flattened in their upper end region and connected to one another and to an underlying support by thermal welding.
  • the disadvantage here is a solid plastic base plate, which means that the roofing element is relatively stiff and heavy and has a high cost of materials with the result of high manufacturing costs.
  • DE-A-32 08 460 shows a facade cladding and roof skin in which a large-area, water-repellent and heat-insulating cladding element is created by the interaction of a lattice-shaped carrier fabric with obliquely woven, tufted or glued, parallel-oriented and offset covered fiber, straw or tube packs for buildings.
  • a disadvantage of this cladding is that the connection between the stalks and the carrier fabric is only slightly resilient, which leads to a low durability of the element as a whole.
  • a roofing element which is composed of a plurality of straws, for example made of PVC, which are embedded with their upper end in a synthetic resin carrier plate. The stalks have different lengths.
  • This roofing element requires a very high amount of material and time in its manufacture and has a high basis weight, which limits its usability.
  • the roof covering element has an underlying support, which consists of a grid-shaped fabric and is connected to the end regions of the straws or of the element by thermal welding, the carrier at least extends over the area of thermal welding.
  • the tissue of the carrier is at least partially penetrated by the material of the stalks and is thus intimately connected to the latter.
  • the fact that at least some of the fibers of the carrier's fabric run transversely or diagonally to the longitudinal direction of the straws largely prevents the element from tearing open in the longitudinal direction of the straws.
  • the support can also be used for fastening the element to a roof surface if it protrudes beyond the element.
  • the material for the stalks is hard PVC or impact-resistant hard PVC, because it combines the required properties - rigidity, weather resistance, formability, colorability and weldability. It is advantageous for the most natural possible visual impression of the element that the blades are of uneven length and irregular in shape at their free ends. This shape of the stalks can e.g. can be achieved by cutting stalk bundles with a very coarse saw. Finally, in order to achieve the most natural possible appearance and good water absorption and water drainage ability, it is provided that the stalks have at least one longitudinally projecting web or wing on their outside. This results in a larger surface area of the stalks and increases their resistance to wind kinking.
  • a roof covering element is created that is simple and inexpensive to produce, that can be installed with little work, that ensures good water absorption and drainage, that is windproof and long-lasting, has a low basis weight and a natural thatched roof offers a very similar visual impression.
  • an alternating color shade is provided within the stalk in the manner of the natural thatch. This Color change can be generated relatively easily by changing the amount of dye added to the plastic mass during the production of the straw and is therefore very durable.
  • the roof covering element according to the invention is advantageously laid in such a way that the element in the welded area is connected to the roof surface by nailing and / or stapling.
  • This laying process is simple and quick to carry out and requires neither special knowledge nor special tools. Since the welded area of one element is covered by the straws of the next element, neither the welded area nor the nailing or stapling is optically disruptive, but the result is a homogeneous arrangement of straws.
  • roof covering element according to the invention can be adapted to bulges, curves and bends of the roof surface by heating to temperatures in the region of the softening temperature. This ensures tension-free laying of the elements without visually disruptive kinks in the roof area in the area of eaves, dormer windows and the like. This also allows the use of relatively large and rationally manufactured and installed elements.
  • the example of the roofing element 1 shown consists of a plurality of stalks 2, which are arranged approximately parallel next to and above one another in the form of a flat rectangle. In their upper end regions 21, the stalks 2 are flattened and joined together by thermal welding. As a result, a largely flat, relatively thin welding area 5 is formed, which is underlaid by a carrier 3.
  • This carrier 3 is a lattice-shaped fabric which is also connected to the upper end region 21 of the straws or of the element by thermal welding. Both welding processes are expediently carried out in one operation.
  • the part of the carrier protruding beyond the element 1 can serve for better handling of the element during manufacture and can be used for fastening during laying.
  • the stalks 2 are unevenly long, the length of the stalks 2 preferably decreasing from bottom to top.
  • the blades 2 are irregularly shaped at their free ends 22.
  • Figure 2 finally shows a plastic straw 2 for use in the roofing element according to the invention in cross section.
  • the basic shape of the cross section is a spiral that resembles an open six.
  • the stem 2 has on its outside 25 approximately radially outwardly projecting webs or wings 4. These webs or wings 4, two are arranged in the example shown, serve to enlarge the surface of the straw 2 and to increase the kink resistance. Herduch and due to the shorter required straw lengths, the roofing element 1 and thus a roof covered with it is very insensitive to strong winds.
