Definitions

  • the invention relates to a joint tape made of elastically deformable material such as plastics or rubber for insertion in expansion joints in buildings made of concrete, this joint tape having beads on the edge and / or at least on one side for anchoring in concrete.
  • Joint tapes of this type are known in many embodiments. They generally have a band-like central strip to be inserted into the joint, which can be deformed in the transverse direction and thus absorbs the movements of the building.
  • the median stripe laterally merges into two wide strips, which are concreted in and anchored in concrete by beads formed on the strips. Depending on the design and intended use, these beads are only arranged on the edge of the joint tape or on both sides of the sheets or only on one side of the sheets.
  • These joint tapes not only have the task of permitting movements of structural parts relative to one another which can be attributed to various causes (temperature changes, shrinkage of the concrete, rigidity of the construction, type of building materials used, etc.), they also have the task of sealing.
  • Injection hoses are also known (DE 33 20 875 A1; DE 84 25 518 U1), which have a liquid-permeable, cylindrical wall, a holding body and, if appropriate, a protective sheath surrounding the holding body.
  • Such an injection hose is intended to ensure a secure seal against the ingress of liquid from the outside inwards, but on the other hand to ensure easy opening under the introduction pressure of the injection liquid.
  • the cylindrical wall consists of a soft, liquid-impermeable rubber or rubber substitute, is arranged within the holding body and has a longitudinal gap running along its length, which in the manner of a lip seal before the injection of the injection liquid in the Holding body is kept closed and can be opened under the introduction pressure of the injection liquid with elastic evasion of the correspondingly soft wall material delimiting the longitudinal gap.
  • the invention now aims to form a joint tape of the type mentioned so that it can still be influenced after its laying and incorporation in the masonry, in such a way that leaks that can be determined subsequently can be remedied.
  • the invention proposes that a tube-like seal is connected to at least one of the beads, that the tube-like seal has a groove which corresponds essentially to the head cross-section of the bead in terms of size and shape for receiving the bead, that the longitudinal cavity of the seal also the groove for receiving the bead is connected and / or the wall of the seal preferably has slots or bores leading to the outside on the side opposite the groove for receiving the bead.
  • 1 to 3 each show a partial cross section through a joint tape, each with differently designed tubular seals.
  • the joint tape 1 has a highly deformable, channel-like central part 2 as well as laterally adjoining tracks 3, on which here beads 4 of essentially mushroom-like cross section are molded on one side.
  • a tubular seal 5 is connected to one of these strip-like beads 4.
  • This thick-walled tubular seal 5 made of plastic has a cavity 6, an outer longitudinal groove 7 with an insert 8 made of reversible compressible material, for example made of foam rubber.
  • the bottom of the groove is connected to the longitudinal cavity 6 via bores 9.
  • a large number of such bores are present along the length of the seal 5 and are spaced apart from one another. Instead of such individual bores 9 distributed over the length of the seal 5, a continuous longitudinal slot could also be present.
  • a further groove 10 is provided, which, in terms of its size and its cross section, is designed to correspond to the head of the bead 4.
  • the seal made separately from the joint tape 1 is drawn onto the bead 4, it is dimensioned so long that it expediently projects beyond the joint tape on both sides, these sections of the joint tape 1 protruding from the formwork for the construction of the masonry.
  • further longitudinal grooves can be provided along the circumference of the seal, in which inserts are inserted, which swell from contact with water Material.
  • Such materials are known for example from DE-OS 4226 198 or DE-OS 4226 385.
  • a hose-like seal is used in this known device, specifically in the longitudinal cavity 6, an injection liquid at high pressure, for example at 200 bar.
  • This injection fluid which is under high pressure, then emerges via the bores 9 and via the groove 7, the insert 8 being compressed, and then flows into the joints and cracks, where it then hardens and creates the required tightness.
  • the longitudinal cavity 6 is connected via bores to the groove 10, which serves to fix the seal 5 on the bead 4.
  • the groove 10 has received the bead 4 or its head with play, or if transverse ribs or flat elevations are formed on the bead, which are associated with the Seal 5 flat channels form for the passage of the injection liquid.
  • transverse ribs or flat elevations on that portion of the bead 4 which is received by the seal can be molded during the extrusion of the joint tape.
  • the embodiment according to FIG. 3 corresponds to the embodiment according to FIG. 1 as far as the fixing of the seal 5 on the bead is concerned.
  • the tube-like seal 5 is provided over its length with a slot 11, through which the injection liquid can escape if necessary.
  • This longitudinally extending slot is expediently provided on one side of the hose-like seal 5, which faces away from the groove 10 for receiving the bead. It should be noted that this slot 11 does not generally run directly radially, but rather in an arc shape, as shown in FIG. 3, with a cavity being cut out at least on one side of the slot, through which the valve action of the slot 11 can be supported .
  • this cavity which is arranged to the side of the slot 11 and extends parallel to the longitudinal cavity 6, 8, is not shown in FIG. 3. It is a circumferentially closed cavity which extends laterally of the slot 11, at right angles to the plane of the drawing sheet according to FIG. 3 and which forms a type of spring which enables the edges of the slot 11 to diverge elastically when a pressure is applied in the longitudinal cavity 6 by means of the Injection liquid is built up.
