Definitions

  • the invention relates to an expansion joint tape according to the preamble of patent claim 1.
  • Such expansion joint tape made of elastic material, in particular synthetic rubber, for example, is made EP-A-0 440 870 known and has a central portion for bridging a Baufuge and two lateral edge portions where practically inextricable side strips are attached as a primer to the building.
  • the side strips are applied or pressed on both surfaces of the edge sections, and flush with their longitudinal edges.
  • the side panels may be woven, nonwoven, bituminous, or a combination of these materials. They can be stepped at the central portion or pressed into the material of the edge portions to allow a favorable cross-introduction or sealing.
  • Joint tapes are used to bridge expansion joints in bituminous waterproofing and between concrete components.
  • the side strips are flamed by flame in the bituminous surface seal or glued with an epoxy adhesive directly to the substrate.
  • the heated and fused areas or glued areas are then merely compressed to form the adhesive bond and seal.
  • the present invention is based on the object, a expansion joint tape in such a way that it has a particularly simple structure and is suitable for a wide range of applications.
  • the invention has the advantage that the expansion joint tape can be stretched over the entire width and is therefore particularly suitable for difficult transitions, for example steps between components, in particular concrete components, since different dilatations can be bridged by the expansion joint tape.
  • FIG. 1 a first embodiment of an expansion joint tape 1 of a sandwich-type construction comprising a first or upper web 2 of vulcanized butyl elastomer, a second or middle web 3 of unvulcanized ethylene-propylene-diene rubber (EPDM) and a third or lower web 4 is formed of vulcanized butyl elastomer.
  • This expansion joint tape 1 has no defined expansion range, but is stretchable over the entire width with the same elasticity.
  • Butyl elastomer shows excellent properties against weathering and a very good flexibility even at low temperatures to about -40 ° C.
  • butyl elastomer has good properties in application on the construction site.
  • a middle web 3 made of EPDM it is also possible to use a laminating film made of polypropylene (PP), polyethylene (PE) or a copolymer.
  • the thickness of the laminating film 3 made of PP or PE is between 0.05 and 0.2 mm.
  • FIG. 2 a second embodiment of the expansion joint tape 1 is shown, in which the webs 2 and 4 by means of two central webs 6 and 7 of non-vulcanized EPDM, a copolymer, PP or PE are interconnected, creating a shallow chamber 8 between the two webs 2 and 4 remains open.
  • This chamber 8 serves to check the tightness of the expansion joint tape 1 over a greater length by the flat chamber 8 is inflated with compressed air and the pressure drop over a certain period of time is measured (or with vacuum).
  • FIG. 3 shows a compound 10 between a layer 11 of a butyl elastomer and a thin film 12 of a copolymer, PE or PP.
  • the film 12 has a thickness of 0.05 to 0.2 mm and the layer 11 has a thickness of 1.0 to 2.5 mm.
  • the film 12 of copolymer, PE or PP is pressed by means of a hot plate at a temperature of about 180 ° C for about 30 seconds on the layer 11, after which the film 12 is excellent on the layer 11 adheres.
  • the film 12 lies evenly and even on the layer 11.
  • compound 10 is used as an intermediate to bond two sheets 13 and 14 of vulcanized butyl elastomer together.
  • the compound 10 is overlapped over the two webs 13 and 14 and then heated with a hot plate to a temperature of about 185 ° C and by means of pressure plates under a contact pressure of 2 to 8 bar, preferably 5 bar, while about two to three Minutes compressed. This results in a tear-resistant connection between the layer 11 and the two webs 13 and 14th
  • FIG. 5 For example, a joint 15 between a layer 11 of a butyl elastomer 11 and two outer thin films 12 of a copolymer, PE or PP is shown. With these thin films 12 further connections can be made with layers of butyl elastomer arranged on both sides.
