Definitions

  • the present invention relates to a method for producing a bituminous sheet with a carrier provided on at least one side with a bituminous cover layer provided with a pattern of parallel grooves and intervening ribs. It further relates to a bituminous sheet having a support provided on at least one side with a bituminous cover layer provided with a pattern of parallel grooves and intermediate ribs, the ribs immediately adjoining the underlying bitumen cover layer
  • US 2001/051252 A1 is a bituminous membrane is known in which a continuous bitumen layer is applied to a carrier on the top and on the bottom of individual rectangular bitumen pieces are applied. Between the Bitumen consultancyen the carrier remains uncoated, so there is no bonding and thus a vapor pressure equalization is possible.
  • Out FR 2706506 A1 is a bituminous sheet with a carrier known, which has on the bottom of a bitumen layer, which is covered with a film.
  • the film has openings in the area of additional bitumen is applied.
  • the web glues only in the area of the openings of the film, so that the bituminous sheets remain relatively independent of the substrate after installation.
  • a method or a bituminous membrane of the above type is known from EP 483274 B known.
  • the bituminous membrane described there is, as usual, provided with a release film which prevents the individual layers of the web from sticking together as long as it is rolled up.
  • the release film and on the other hand the cover layer is so soft that it sticks to the substrate.
  • the purpose of the grooves is that less energy is needed to heat the bituminous sheets, which not only results in energy savings, but also - for a given power of the propane gas burner - also make a higher installation speed possible. According to this document, such bitumen sheets can be produced by combing the material while it is still hot and viscous.
  • the spacing of the grooves is a maximum of 10 mm, preferably between 1 mm and 5 mm.
  • a disadvantage of this method is that the material of the ribs, which remains between the grooves, and the material of the underlying layer is inevitably identical. As a result, such bitumen membranes can only be optimized poorly for certain purposes.
  • This object is achieved according to the present invention by a method of the type mentioned in that applying a layer of bituminous compound evenly on the carrier and that then applying the applicator roll directly on the layer of the ribs.
  • the ribs are formed by additionally applied material. In this way, it is possible for the material of the ribs to be different from the underlying material of the bitumen cover layer.
  • the corresponding bitumen sheets are thus characterized in that the material of the ribs differs from the material of the underlying bitumen cover layer.
  • the present invention can be applied to self-adhesive bitumen membranes.
  • Self-adhesive bituminous membranes do not need to be heated but stick together on their own when they are laid on a suitable substrate.
  • a disadvantage of these webs is the increased price, because the self-adhesive material is more expensive than conventional, hot-to-bond bituminous mass.
  • the present invention it is possible to provide that only the material of the ribs is self-adhesive.
  • the underlying under the ribs bituminous mass may consist of less expensive material.
  • the ribs In the case of a self-adhesive bituminous membrane, the ribs have the advantage that the release film does not lie all over, but only in the uppermost region of the ribs. If the release film is applied over the entire surface, it is often difficult to remove the film, especially on hot days, especially if this is interrupted. Then it can happen on hot days, namely that the soft bitumen creeps up on the release film, so that the necessary to remove the film acute angle can not be achieved.
  • the ribs are not used according to the invention for vapor pressure equalization. you may therefore be relatively thin, ie the distance of the ribs from tip to tip is preferably only between 1 mm and 10 mm, more preferably between 1 mm and 5 mm. Narrow ribs have the advantage that they can flow after laying, so that ultimately a full-surface or at least almost full-surface bonding can occur.
  • FIGURE shows a bituminous sheet according to the invention in section.
  • a textile carrier 11, for example, is impregnated with bituminous material, so that bituminous material 12 is located above the carrier 11 and bituminous material 13 below the carrier 11.
  • This bituminous material 12, 13 is conventional, non-self-adhesive and thus inexpensive material.
  • ribs 14 are provided, which consist of self-adhesive bituminous material, which is more expensive. It is immediately apparent that comparatively little of the expensive material is needed. Nevertheless, you get a full-fledged self-adhesive bituminous membrane.
  • This self-adhesive bituminous membrane is even superior to conventional self-adhesive bituminous membranes, because the necessary release film 15 does not rest on the entire surface, but touches the ribs 14 only at their outermost regions. The release film 15 can therefore be deducted without difficulty even on very hot days, at which the bituminous mass is already viscous.
  • Two concrete bituminous membranes have the following structure:
  • Carrier polyester fleece Covering compound: SBS bitumen (4 mm incl. Carrier) Groove dimensions: APP bitumen (about 1 mm) Surface above: slate Surface below: cut-off foil
  • Carrier glass fabric Covering compound: SBS bitumen (3 mm incl. Carrier) Grooved mass: self-adhesive (about 1 mm) Top surface: sand or weld-off foil Surface below: peel-off film
