  • the WO 97/09504 A1 discloses such an insulating bridge and composite profile, each extending in a longitudinal direction.
  • the insulating bars are designed as hollow chamber webs. In these hollow chamber webs, hollow chambers extend in the longitudinal direction, ie in such a way that in a cross section perpendicular to the longitudinal direction the hollow chambers have a closed cross section.
  • the insulating bars are connected to the profile parts by rolling.
  • Such hollow chamber webs with one or more hollow chambers are also known from the brochure "Standard Profiles 2010" of the TECHNOFORM BAU-TEC, eg the standard profile with the article number 299000 shows a hollow chamber profile with a hollow chamber and the hollow chamber profile with the article number 384200 shows a hollow chamber profile with three hollow chambers , More insulating bars with hollow profile are from the DE 42 38 75.0 A1 in the WO 97/09504 A1 known as the prior art known. In the DE 42 38 750 A1 the multi-chamber hollow sections are made of two parts with different wall thicknesses and welded, for example.
  • Each insulating bars are known with individual hollow chambers, which are assembled from two Isoliersteg.
  • the two Isolierstegmaschine are designed so that the respective curl body are formed in two parts for rolling in grooves of the profile parts and can be plugged together. After curling the mating Isolierstegmaschine are held relative to each other in position.

  • This ladder-like design allows limited longitudinal displacement of the profile parts.
  • the insulating web has a cover which is formed integrally with the Isolierstegsammlung and can be clipped to the Isoliersteg Congress and completely covers the recesses in the clipped state.
  • Insulating webs with one or more hollow chambers and method for introducing support foam in the same are from the EP 0 978 619 A2 known.
