Definitions

  • the invention relates to a sealing tape for sealing a joint, for example between a frame profile of a window or a door and a building wall.
  • a pre-compressed sealing tape which consists of a resiliently elastic foam strip of rectangular cross-section, which is completely enclosed in the compressed state by a sheath which is formed by a plastic film.
  • the plastic film forms a running in the longitudinal direction of the sealing strip tear tab by the plastic film is arrested to form a predetermined breaking point against itself.
  • the foam strip is glued on its underside with the wrapper, and the wrapper is in turn on its underside with separate adhesives, such as a double-sided adhesive tape, attachable to a frame profile.
  • Sealing tapes of this type are adhered to the frame profile to be sealed, and after installation of the frame profile in a building wall opening the enclosure is torn open to allow the foam strip to resiliently reset and thus seal the frame profile on the building wall.
  • these known sealing tapes it is disadvantageous that they can only be produced in relatively small widths, since otherwise due to the restoring force of the precompressed sealing tape, an oval to round shape results within the envelope, which is unsuitable for installation.
  • Sealing tapes which consist of a combination of a soft foam strip with a foil are also made EP 1 936 246 A and EP 1 936 247 A known. These sealing tapes provide improved sealing properties due to the definable position of the film in the installed state. However, such sealing tapes are not well suited for deep joints.
  • a sealing tape which consists of a flat bar for adhering to a frame profile and a foam strip arranged thereon.
  • the foam strip is covered by a sheet of paper or plastic, which is glued to the flat bar and keeps the foam strip in the compressed state.
  • Edge strips of the covering film run tear-open threads, with the help of which the film can be torn open after installation of the provided with the sealing strip frame profile in the building.
  • WO 98/45565 A describes a sealing strip of foam, which is surrounded by a sheath.
  • a rigid layer of cardboard or plastic may be provided. After opening the foil-like wrapping the foam strip expands a little in the sealed joint in which he is loosely inserted.
  • the invention has for its object to provide a sealing tape that is simple and easy to handle and seals excellent sealing with low material consumption joints of any depth.
  • the sealing tape comprises a first foam strip having a top side and a bottom side, a second foam strip having a top side and a bottom side, and a film-like connecting element having a first fastening section, a second fastening section and an intermediate section therebetween, wherein the first fastening section is at least partially attached to the first foam strip, the second attachment portion is at least partially attached to the second foam strip, and the central portion, when viewed in a straight extended state, extends from the top of the first foam strip to the bottom of the second foam strip.
  • the consumption of foam material can be considerably reduced with large joint depths, and due to the defined position of the film-like connecting element a secure sealing of the joint can be ensured.
  • the film-like connecting element is protected in this structure from damage during transport or handling.
  • the central portion of the film-like connector is not attached to the first or second foam strip. This achieves a greater variability of the sealing tape for a variety of applications.
  • a first self-adhesive layer may be disposed on the underside of the first foam strip, which is covered by a first cover.
  • a second self-adhesive layer which is covered by a second cover film, may be arranged on the underside of the second foam strip.
  • the second self-adhesive layer is arranged below the second fastening portion of the film-like connecting element.
  • first self-adhesive layer and the second self-adhesive layer may be integrally formed with each other and formed by a one-piece stretchable self-adhesive strip.
  • a further self-adhesive layer which is covered by a further covering film may be arranged on the upper side of the first foam strip.
  • a further self-adhesive layer which is covered by a further covering film can furthermore be arranged on the upper side of the second foam strip.
  • a simple and secure attachment of the film-like connecting element to the foam strip is achieved if the first fastening section and the second fastening section of the film-like connecting element are fastened to the first and second foam strips by means of an adhesive layer.
  • This adhesive layer can be dispensed with if the double-sided self-adhesive layers are used as adhesives, which actually serve for fastening the sealing strip to the component. This is achieved by the fact that the first attachment portion and / or the second attachment portion of the film-like connecting element has recesses.
  • the sealing tape For a safe and space-saving storage of the sealing tape, it can be wound into a sealing tape roll.
  • the first foam strip and the second foam strip can be wound next to each other around a take-up, whereby the handling is easier to use.
  • first foam strip and the second foam strip may be wound one above the other around a take-up sleeve so that the width of the seal tape roll is minimized.
  • a component to which a sealing strip according to the invention is fastened is preferably characterized in that the first foam strip and the second foam strip are arranged next to one another and an intermediate space is formed between the first and second foam strips through which the film-like connecting element extends.
  • foam strips, film-like connecting elements, adhesive layers and covering films are partially shown at a certain distance from each other to clearly distinguish the individual elements that form the sealing strip. In reality, these elements are closely related.
  • a sealing tape which has at least one first foam strip 2 and a second foam strip 4.
  • the foam strips 2, 4 have a rectangular cross-section, but also any other shapes are conceivable.
  • the foam strips 2, 4 may be formed of any open cell or closed cell flexible foam, for example of polyurethane or polyethylene, and may be impregnated for delayed recovery after compression. The density of such flexible foams is between 20 and 200 kg / m 3 .
  • the materials of the first foam strip 2 and the second foam strip 4 may differ from one another, for example to ensure different air permeabilities of the sealing tape in the interior and exterior or a vapor diffusion gradient.
  • the width of the foam strips 2, 4 may also be different, as well as their height or their impregnation.
  • the foam strips 2, 4 are usually precompressed so that they can expand when relaxing preferably to about five to ten times their occupied in the pre-compressed state thickness, but often only about half is utilized to secure investment to ensure the building part, which is opposite to the profile element to be sealed.
  • the foam strips 2, 4 extend in their longitudinal direction further than in their transverse direction. Connected are the two foam strips 2, 4 via a film-like connecting element. 6

  • the term "adhesive layer” used above should therefore also encompass adhesive layers of this type described here. This also applies to all other adhesive layers and self-adhesive layers mentioned in this document.
  • the first adhesive layer 10 is designed as a double-sided adhesive tape, which establishes a firm adhesive bond between the first foam strip 2 and the first attachment section 8 of the film-like connecting element 6.
  • the solid compound can also be made by other means, such as thermoplastic lamination.
  • the first adhesive layer 10 is formed on the upper side 12 of the first foam strip 2 and covers it completely. It is also possible that the adhesion of the film-like connecting element 6 is realized with the first foam strip 2 only in a partial region of the top 12 of the first foam strip 2, or that the film-like connecting element 6 passes over the top 12 of the first foam strip 2, but on one of its side surfaces or on its underside 14 is fixed, although this is not shown in the illustrated embodiments. Likewise, only a selective attachment of the film-like connecting element 6 on the first foam strip 2 is conceivable. These statements apply analogously to the second foam strip 4.
  • the film-like connecting element 6 has a second fastening section 16 which is at least partially fastened to the second foam strip 4.
  • the attachment of the second fastening portion 16 is preferably carried out by means of a second adhesive layer 18, which is preferably arranged on the underside 20 of the second foam strip 4.
  • the film-like connecting element 6 has a middle section 22 which extends from the upper side 12 of the first foam strip 2 to the lower side 20 of the second foam strip 4 extends.
  • This central portion 22 of the film-like connecting element 6 is preferably not attached to the first or second foam strips 2, 4, but is exposed.
