Definitions

  • the invention relates to a sealing profile for embedding in a molded part made of hardenable material, in particular a concrete or plastic molded part, as well as a molded part and a sealing arrangement with the sealing profile.
  • Shaft and tunnel structures are regularly made up of individual monolithic prefabricated components (e.g. segments) between which there are contact joints that are sealed with suitable seals to prevent, for example, the penetration of surrounding medium (e.g. water).
  • the manufacture of such prefabricated components is usually carried out using formwork forms, such as those made from DE 4218710 C1 , EN 10 2007 032 236 A1 or DE 19841047 C1 known.
  • a hardenable material e.g. concrete, is poured into the formwork, which is opened and removed after the material has hardened.
  • Seals for sealing the contact joints can be subsequently arranged in the circumferential grooves provided for this purpose in the butt sides of the cured molded part.
  • An example of such a seal is shown in DE 2833345 A1 described.
  • seals that are required to seal the joints that later arise when the prefabricated components are assembled to form a shaft or tunnel are often integrated into the prefabricated components during casting by being cast in and anchored. Such seals are also referred to as integrated seals or anchored seals.
  • integrated seals which are intended to be embedded in prefabricated components made of hardenable material, such as pipes, segments, shaft rings and the like, are usually provided with so-called anchoring feet at their base, which are enclosed by the hardenable material when the prefabricated component is cast and are intended to reliably hold the seal in the hardened prefabricated component.
  • seals are regularly equipped with projections or the like, with the help of which they can be arranged in a suitably designed holder of a formwork mold and held during the casting process so that the seal with its anchoring feet in towards the interior of the formwork and can be embedded in the hardening material.
