Definitions

  • the invention relates to a joint tape, such as an expansion joint tape, for the active, automatic, permanent sealing of joints between or in structures and / or parts thereof with an elastic plastic-like material, an expansion joint tape connection device for connecting waterstops, an easily relocatable joint sealing arrangement with expansion joint tapes and expansion joint tape connection devices.
  • a joint tape such as an expansion joint tape
  • an expansion joint tape connection device for connecting waterstops
  • an easily relocatable joint sealing arrangement with expansion joint tapes and expansion joint tape connection devices Use of the waterstop to seal expansion joints, construction joints, expansion joints, standing joints, etc. as well as a method for installing waterstop prior to concreting.
  • expansion joints In the case of structures that are built with large-area concrete elements or that have such concrete elements, expansion joints must be formed between adjacent concrete components, such as structural parts, in order to be able to compensate for both mechanical tensions between the components and their temperature-related geometric changes.
  • Common expansion joints envisage the embedding of an elastomer body as an expansion joint tape between adjacent components that form the joint.
  • Joints are created by joining parts of structures. It is precisely necessary that the joint seal must meet the requirements for moisture, fire, heat and / or sound insulation.
  • conventional, one-piece expansion joint tapes running in the form of a tape and having a diamond-shaped cross-section are used.
  • the conventional expansion joint tapes are characterized in that their two sealing strips are designed in the form of two triangles in cross section with a common hypotenuse; their hypotenuse corresponds to an axis of symmetry, so that the triangles form an axially symmetrical figure by folding over around the axis of symmetry.
  • These wedge-like sealing strips arranged in the joints with their opposing wedge tips have only inadequate sealing properties.
  • the reinforced concrete ceiling usually has reinforcing steel inserts, which are referred to as reinforcement and are able to absorb tensile forces in order to increase the compressive strength of the reinforced concrete ceiling and to limit the formation of cracks.
  • reinforcing steel inserts which are referred to as reinforcement and are able to absorb tensile forces in order to increase the compressive strength of the reinforced concrete ceiling and to limit the formation of cracks.
  • the conventional expansion joint tape is set with its one lower wedge-like sealing strip against the reinforced concrete ceiling, the other upper wedge-like sealing strip is aligned with its wedge tip in the opposite direction in order to fill the space delimited by the formwork with concrete mass.
  • the conventional expansion joint strips due to their displaceability, provide an advance for the penetration of moisture via the intermediate space formed between the conventional expansion joint tape and the expansion joint.
  • an expansion joint tape is described as a sealing profile for arrangement in structural joints with a longitudinally extending sealing body, which has at least one through opening extending from an underside to an opposite top side of the profile body for injecting a sealing material into the joint.
  • the conventional sealing profile also has the disadvantage that Despite injecting an additional sealing material into the sealing profile, the migration of the sealing profile by water due to capillary forces between the outer sides of the conventional sealing profile on the one hand and the inner sides delimiting the expansion joint on the other hand is not prevented.
  • the parts of the building perform relative movements to one another, e.g. characterized by expansion, by building parts drifting apart from each other.
  • This drifting apart of the structural parts already detaches the conventional sealing profile from the expansion joint and enables water to penetrate from the outside to the inside via the expansion joint.
  • the drifting apart of the structural parts from one another causes high material stress as a result of the expansion, since the drifting apart of the structural parts with the displacement of the structural parts to each other and thereby at least partial compression of the conventional sealing profile is associated, so that the result of the injection of sealing material into the conventional sealing profile is less elastic training of the same leads to bruises, the result of which are cracks and crevices. Via cracks and crevices, water, but at least moisture, penetrates not only into the expansion joints, but also beyond the expansion joints into the interior spaces spaced apart from the expansion joint.
  • the conventional sealing profile is also squeezed by the sole movement of the structures to one another as relative movements, which show up as compression of the structural parts, so that the cracks and gaps that arise as a result also encourage the penetration of moisture.
  • the expansion joint tape to be provided should have sufficient expansion capacity and be characterized by its particular fidelity in the joints, such as expansion joint, that means: the intimate connection of the expansion joint tape with the concrete compound or casting compound forming the expansion joint should be maintained.
  • the expansion joint tape should also be tolerant of relative movements of the structural parts and, as a result, provide a sufficiently permanent seal for the joint between them, the relative movements being due to various causes, e.g. Changes in temperature, shrinkage of the concrete, rigidity of the structure, type of building materials used and the like.
  • the expansion joint tape to be provided should be firmly embedded in the parts of the structure so that the security of the expansion joint tape is not impaired even if the structural parts move away from each other, i.e. the flat connection between the expansion joint tape on the one hand and the expansion joint on the other hand is maintained.
  • the expansion joint tape to be provided should compensate for the tensile forces acting on it while maintaining the intimate connection, such as the flat contact of the expansion joint tape against or against the inside bounding the expansion joint.
  • the expansion joint should also adapt to the large changes in the gap bridging the expansion joint caused by seismic factors such as earthquakes or train, motor vehicle or tram driving at sometimes high speed, without the waterproof, sound-absorbing ones and / or the heat-insulating properties of the expansion joint tape are impaired.
  • the expansion joint tape should also be able to suppress the penetration of water or moisture via these imperfections.
  • expansion joint tape to be provided should also seal the gap between the structures against high water pressure.
