  • the hollow chamber profile according to the invention provides that the channel side walls are at a greater distance from one another in the intermediate region than in an area of the partial fastening channels. In this way, sufficient space can be created in the intermediate area for the introduction of a suitably sized reinforcement profile.

  • At least one terminal web is arranged on at least one of the projections, preferably at least two terminal webs.
  • Such webs can form an advantageous positive connection with insulating or fastening material at the interface to the building.
  • At least one of the projections has at least one further projection on its inside facing the free space, preferably a projection with a triangular cross section.

Above this hollow chamber 100b, the profile element 100 has a recess 100i, which serves to accommodate the channel projection or the screw chamber 7.2. So the profile element 100 can fill the free space 16 without any protrusion.
  • the screw chambers 7.1 and 7.2 have lateral thickenings or accumulations of material on their (screw channel) side walls, which are not marked in the figures mentioned for reasons of clarity.
  • Figure 5 shows the same hollow chamber profile 1 as in Figure 4 , again with an additional profile element (sill) 100 inserted in the free space 16 and fastening screw 3 (with edge-side profiling 3a) for fixing the hollow chamber profile 1 to a building 4.
  • profile element 100 inserted in the free space 16 and fastening screw 3 (with edge-side profiling 3a) for fixing the hollow chamber profile 1 to a building 4.
  • edge-side profiling 3a edge-side profiling 3a
  • a stiffening element 200 which is preferably designed as a flat steel element and is inserted into the area between the webs 100c, 100d and an outer wall 100j of the profile element 100.
  • the said webs 100c, 100d have mutually facing projections 100ca, 100da at their free ends, so that an undercut is formed in the area mentioned.
  • the stiffening element 200 is held captively between the webs 100c, 100d and preferably also on the outer wall 100j.
  • the fastening screw 3 preferably also passes through the stiffening element 200.
  • Figure 6 shows a further hollow chamber profile 1, not according to the invention, which essentially corresponds to the profile Figure 3 corresponds.
  • the main differences will only be briefly discussed here:
  • the reinforcement chamber (the intermediate area 10) is not double-walled on the left and at the top.
  • the fastening channel 7 has only one screw chamber (at reference number 7.2), which screw chamber shows a (locking) projection 7.2a.
  • the projection 14 has two further projections 14f, 17 on its inside - as already mentioned; the projection 15 has no inside projection.
  • the fold area (at reference number 1a) is essentially flat.
  • the fastening channel 7 is de facto reduced to the partial fastening channel or the only screw chamber 7.2.
  • Figure 7 shows the hollow chamber profile 1 Figure 6 together with the further profile element 100 according to Figure 4 and a fastening screw 3.
  • Figure 7 shows the hollow chamber profile 1 Figure 6 together with the further profile element 100 according to Figure 4 and a fastening screw 3.
  • Figure 8 a section in or parallel to a glazing plane through a frame 20 for a door or a window, in particular a frame, which consists of several sections 1.1-1.4 of the invention Hollow chamber profiles 1 (cf. Figures 3 and 4 ) is formed.

It can be held therein in a clamping, force-fitting manner or in some other way (eg materially bonded) in order to reinforce the connection areas 21.
  • This embodiment is not limited in terms of the type and number of connecting elements 22.
  • the frame 20 can be connected to external components via the hollow chamber profile sections 1.1-1.4 in the manner described, for example with a soffit surrounding or receiving the frame (structure 4, not shown here, cf. Figure 4 , 5 or 7 ).
  • a reinforcement or a reinforcement element is introduced into one of the intermediate areas 10 at reference number 2.
  • the other intermediate areas 10 can also be used in accordance with Figure 5 take up the appropriate reinforcements 2.
  • the reinforcements 2 can also extend into the connection areas 21, which in Figure 5 is not shown.
  • a profile element 100 is arranged as an example.
  • the other free spaces 16 can also be used accordingly Figure 5 accommodate corresponding profile elements 100.
