  • another embodiment relates to the use of the joint tape according to the invention as external, in particular joint tape, as for bridging joints or gaps between structures and / or parts thereof, the design of the top 12 and the bottom 13 of the sideband 2 in cross section in the form of an unequal triangle are formed, wherein the length of the upper surface 12 -extending from the abutting portion 1f to the end 4a of the end portion 4-greater than the length of the bottom 13 of the sideband in cross section and the distance of the top 12 from the bottom 13 evenly from the center piece. 1 towards the end 4a becomes larger and the end 4a of the end portion 4 is oriented perpendicular to the bottom 13.
  • the height B of the end part 4 corresponds to the height C of the intermediate part.
  • the joint tape according to the invention allows easy handling and a reliable joint seal against water ingress and water penetration.
  • the ingress of water is prevented by increasing the Wasserumlaufweges by the arrangement of the wedge-shaped webs 5 and corrugations 17 on the top 12 and bottom 13 of the sideband second
  • the joint seal against water penetration is made possible by the permanent extensibility of both the center piece 1, which is configured for example in the form of a hollow body-shaped tube 1a with an H-shaped longitudinal cavity 1b, as well as due to the particular tapered in cross-section configuration of the side band 2 in the direction towards the Middle piece 1, so that the expansion capacity of the joint tape according to the invention is not limited to the middle piece 1, but is supplemented by the sidebands 2 and webs 5, without the Ortsverterrorism of the joint tape of the invention is limited in the concrete.
  • the joint tape according to the invention can be formed by pressing, extrusion (extrusion), injection molding, one-piece and cohesive.
  • the joint tape according to the invention can also be produced from thermoelastic plastics, such as elastomers, plastomers and thermosets or mixtures thereof.
  • the joint tape according to the invention is heat-resistant, of sufficient dimensional stability and dimensional stability.
