Definitions

  • the present invention relates to new sealing or insulating sheets made of (polymer) bitumen, especially for roof covering and cladding of basement outer walls, as well Process for laying such new sheets on building roofs and walls.
  • webs are mostly multi-layer, one-sided adhesive ("self-adhesive” or thermally activated, e.g. by "flaming") roof, Sealing and insulating sheets made of polymer bitumen without deposits (homogeneous) or with various inlays or reinforcements (e.g. aluminum foils, glass fabric, glass grids, Glass fleece, plastic fleece and combinations of these fabrics) as well as with different Surfaces (e.g. non-removable foils, natural slate tiles, colored sand particles, Fine sand, talc) is well known in the field.

  • GB-A-2.253.184 discloses webs made of plastic, on the underside of which crossways Extending across the width of the web, abutting one another in the longitudinal direction of the web Insulating panels (made of stone or glass wool, polymer foam, cork, wood wool cement or expanded pearlite) are glued on, the webs being rolled up transported and stored ("taxiways").
  • Surfaces made of synthetic foils are also known, for example serve as a base for subsequent (self-adhesive) sheets or by melting (e.g. with an open flame or hot air) the activation of the adhesive force of the cause the underlying layer of the same sheet and thus an adhesive connection with the next following position of the overall construction (e.g. roof), e.g. insulation, Bitumen membrane etc., enable.
  • the processing of the individual sealing and insulating sheets is usually done by rolling out the individual webs, which are predominantly in shape after production of rolls wound on themselves, on the surface, and usually in an overlapping relationship with each other to avoid bumps between the lanes to avoid, which would pose potential problem areas.
  • the extent of the overlap Depending on the type and purpose of the train, it can range from a few centimeters to half the width of the web, but is preferably in the range of 8-12 cm.
  • the self-adhesive surface is normally on provided the underside, which after winding up on itself the outside of the Represents the roll when it is applied to e.g. Simply roll roofs flat and with the subsurface (e.g. concrete substrate or an underlying track or Thermal insulation).
  • the self-adhesive surface is with a continuous, uninterrupted covering (separating layer) made of (possibly siliconized) Paper, foil or other easily removable material to prevent the Bonding the webs in the roll provided when processing the web on the Construction site is pulled off when rolling up the webs and thus the self-adhesive surface releases.
  • the separation layer is covered in one piece and without any separation aids one side the entire width of the polymer bitumen membrane with different widths (but preferably 1 m) and the entire length.
  • the self-adhesive surfaces usually require a working temperature of at least 5 ° C, preferably at least 9-10 ° C, to ensure sufficient adhesive effect, without the need for thermal activation. If processing temperatures are too low not only is the adhesive effect impaired during processing, but it also suffers from the long-term adhesive performance and therefore under certain circumstances also the tightness of the adhesive connection, i.e. microchannels may develop over time between the surfaces glued together, through the gradual moisture can get under the membrane.
  • US Application No. 5,916,654 describes webs where there is a slot below or a perforation between two sections of the release film is glued to the adhesive surface, the purpose of which is easier removal of the release film from the adhesive surface - due to the weaker adhesion of the film to the strip (in Compared to that on the adhesive surface) - is.

  • it can any other material suitable for this purpose can be used as long as the Advantages of the invention, i.e. the simplification of laying, are retained.
  • FIG. 8a shows the embodiment from FIG. 7b in a longitudinal cross section.
  • Sheets 1 provided with thermal insulation 7 enable a further reduction in time and costs for the roof covering or wall cladding, since there are two layers, namely thermal insulation and the next gasket layer can be installed at the same time.
  • storage and transport of these trains usually takes the form of so-called "Taxiways", i.e. also wound up into a roll, the thermal insulation elements usually point outwards.
  • Taxiways i.e. also wound up into a roll
  • Fig. 8b A variant of these taxiways is shown in Fig. 8b, a track 1 with the top Self-adhesive surface 2, protective cover 3 and predefined dividing line 4 for the
  • Such tracks are usually shorter than taxiways (only about 2-5 m) and are stored folded in the form of so-called “folding lanes", such as shown in Fig. 8c.
  • FIG. 9 finally shows a particularly preferred embodiment of the invention in Cross-section, with at least one of the protective covers located on the edge over protrudes this edge, in particular over its entire length, by a security strip 3 * form.
  • Fig. 9 is - in an analogous manner as in Fig. 5 - the overlapping Laying such tracks shown. The laying direction corresponds in this Again, the right-to-left direction is shown, and laying is similar as described in connection with FIG. 5.
  • each lane does not cover the entire surface by pulling off the marginal part the protective cover 3 of the previous path (along a predefined, not shown Separating line) exposed self-adhesive surface m, but somewhat to the (left) edge stuck on so that there is a strip of self-adhesive surface along the overlap (m-ü) is not covered by the underside of the next track.
  • the protruding one Security strip 3 * of each lane is now bent down over its edge and glued to this free self-adhesive surface 2, so that the (vertical) side surface the web and subsequently the entire surface of all webs with protective cover 3 remain protected before the next layer is applied.
  • the present invention can be applied not only to those described above, but in principle on all e.g. for roofing or insulation of basement outer walls Apply the types of waterproofing and insulating sheeting used - even to those in the top layer of roofing sheets used, if at least still on top another covering (for example a floor covering, roof garden subsoil etc.) follows.
