Definitions

  • the present invention relates to a joint tape for sealing butt joints in concrete construction, consisting of an extruded profile strand made of plastic or rubber with strip-shaped stiffening elements running at right angles to the longitudinal direction of the profile.
  • Such a joint tape is known from DE-PS 30 11 225.
  • the stiffening elements are completely embedded in the profile strand in such a way that the joint tape has the same cross-section throughout the longitudinal direction of the profile. Due to this embedding of the stiffening elements, however, the profile strand must be made very thick overall, which leads to a disadvantageously high material consumption and thus to high manufacturing costs.
  • Another joint tape is known from DE-OS 24 08 514.
  • the stiffening elements are formed by bent steel wires on one side are arranged "outside" of the profile strand.
  • the steel wires have a straight middle part which is in contact with the profile strand and two curved end sections which surround and clamp the edge of the profile strand.
  • the stiffening elements are consequently not embedded here, so that the profile strand can be made thinner, which leads to reduced material consumption.
  • the disadvantage here is that the stiffening elements surrounding the joint tape on the outside can represent bridges for waterways and, moreover, significantly increase the production costs, since continuous production of this joint tape is difficult because the stiffening elements have to be clamped individually by hand. There is also the risk that the stiffening elements fixed on the outside of the joint tape will be lost during transport and / or at the construction site itself.
  • the present invention is therefore based on the object of creating a joint tape of the generic type in which the profile strand can be made thinner and thus less expensive by material, but the stiffening elements should nevertheless be firmly connected to the profile strand and water bridging via the stiffening elements is avoided.
  • a simple, inexpensive, continuous production of the joint tape should also be possible.
  • stiffening elements are each partially embedded in the profile strand in the region of their two ends and extend over a surface of the profile strand in the region lying between the embedded ends.
  • the profile strand can be made practically arbitrarily thin in its area lying between the embedded ends of the stiffening elements, which enables the desired material saving. Nevertheless, the stiffening elements are firmly, captively connected to the profile strand.
  • the simple and inexpensive producibility of the joint tape according to the invention is also particularly advantageous, the stiffening elements being molded in regions during the extrusion process of the profile strand. As a result, the joint tape according to the invention can be produced continuously in only one operation.
  • the stiffening elements each form a water bridge in their area lying between the embedded ends, the so-called water circulation path is advantageously interrupted by the end-side embedding of the stiffening elements.
  • the sealing function effected by edge beads of the profile strand according to the so-called labyrinth principle is fully retained.
  • a joint tape 2 consists of an extruded profile strand 4 made of an elastic material, such as plastic or rubber (rubber).
  • the profile strand 4 has a thickened edge bead 6 on each of its two longitudinal edges. These edge beads 6 cause an extension or interruption of the water circulation path to avoid water cross bridges.
  • a positive connection between the joint tape 2 and the concrete enclosing it is also achieved by the edge beads 6.
  • the joint tape 2 also has a plurality of strip-shaped stiffening elements 8 which run transversely to the longitudinal direction of the profile and are spaced apart from one another and preferably have a flat, rectangular cross section.
  • the stiffening elements 8 can have a width of 5 to 8 mm and a thickness of 1 to 1.5 mm.
  • the mutual distance of the stiffening elements 8 from one another is advantageously 10 to 15 cm.
  • the stiffening elements 8 suitably consist of metal or a rigid plastic, for example hard PVC.
  • the stiffening elements 8 serve to stiffen the joint tape 2 in the transverse direction in such a way that it can always be laid out flat.
  • the stiffening elements 8 are now only partially embedded in the profile strand 4 in the area of their two ends 10. Im between the embedded Stiffening elements 8 advantageously lie essentially at the ends 10 of the area 10 of the profile strand 4. In the exemplary embodiment shown, the stiffening elements 8 lie directly on the surface 12 of the profile strand 4. However, it is also possible that the stiffening elements 8 are integrally connected to the profile strand 4 in this area or, due to the production of the joint tape 2 in the extrusion process, at least partially stick to the profile strand 4 superficially.
  • the profile strand 4 has ribs 16 running in the longitudinal direction of the profile on its side 14 opposite the stiffening elements 8. These ribs 16 also serve to improve the sealing effect of the joint tape according to the invention and also for a positive connection between the joint tape 2 and the concrete.
  • the stiffening elements 8 i.e. on the surface 12, on the other hand, there is no need for such ribs, since these would be bridged by the stiffening elements 8 anyway.
  • the surface 12 can therefore be formed without profiling.
  • the ends 10 of the stiffening elements 8 according to the invention are embedded in retaining ribs 18 formed on the surface 12 of the profile strand 4 and extending in the profile longitudinal direction.
  • These holding ribs 18 are expediently formed in the transition area between one of the thickened edge beads 6 and the surface 12 of the profile strand 4.
  • At least one further rib 20 is formed in each case in the region of the holding ribs 18.
  • the embedded ends 10 of the stiffening elements 8 are also connected to the profile strand 4 in a material and / or form-fitting manner.
  • the stiffening elements 8 each have at least one through hole 22 in their embedded ends 10 through which the material of the profile strand 4 or the holding ribs 18 extends in a form-fitting manner.
  • form-fitting material through connections 24 are formed in the area of the through holes 8.
  • a material connection can be provided in the area of the ends 10, for example via an adhesion promoter coating. It is also possible to vulcanize the stiffening elements 8 in the region of the ends 10 into the profile strand 4, which then consists of rubber.
  • the profile strand 4 is connected to an edge strip 26 in the region of at least one longitudinal edge, ie in particular following the edge bead 6, this edge strip 26 having through holes 28 spaced apart from one another in the profile longitudinal direction.
  • the joint tape 2 preferably has an edge strip 26 on both edges.
  • This edge strip according to the invention is used to fix the joint tape 2 before concreting, by pulling a binding or string wire 30 through the eyelet-like through holes 28, whereby then the ends of the wire 30 are braced and fastened, for example, to a wooden casing.
  • the edge strip 26 is cohesive, in particular homogeneous, i.e. Uniform material, is connected to the profile strand 4. It is particularly expedient here if the profile strand 4 is made of soft PVC and the edge strip 26 is made of hard PVC, since these materials can be homogeneously connected to one another, in particular during the extrusion process. This also ensures on the one hand a necessary elasticity of the joint tape 2 or the profile strand 4, but on the other hand also ensures sufficient strength of the edge strip 26, wherein tearing out of the through holes 28 by tensile forces applied via the wire 30 is advantageously almost impossible.
  • the production of the joint tape 2 according to the invention is advantageously very simple and therefore inexpensive.
  • the profile strand 4 and on the other hand the retaining ribs 18 are expediently extruded first, but then brought together in a common extruder or spray head, including the stiffening elements 8, and thus connected in a material-uniform, homogeneous manner by embedding the ends 10 of the stiffening elements 8.
  • This allows continuous production, with the stiffening elements 8 being able to be fed automatically, in cycles.
