Definitions

  • a method for improving the thermal insulation of a hollow chamber profile is for example from DE 43 31 816 A1 known. Due to the increasingly demanding CO 2 savings target in the context of climate change, there is a great need for a sustainable further development of the thermal insulation properties of building elements, in particular window or door profiles.
  • a plastic foam strip is attached to a steel reinforcement and inserted together with this in a hollow chamber of the door or window profile. Due to the steel reinforcement, the thermal insulation properties of the profile described are comparatively poor, which also the introduction of the foam strip can not fundamentally change.
  • the foam material has a comparatively sensitive surface has, which can be damaged during insertion of the profile in the hollow chamber profile, so that undesirable Schaumkrümel arise.
  • the foam strip - if it is not attached to a Stahlarm ist - relatively easy to break because of its large length, making handling difficult.
  • the insulation profiles may only have a relatively short length (about 1-2 m), because the introduction of longer profiles leads to the breaking of the same.
  • the DE 100 35 649 A1 shows a method for foaming window profiles, in which after profiling via a continuous slot in the profile wall, introduction of foam material by means of a fixed lance, through which the foam material flows takes place.
  • this method has the disadvantage that the slot to be closed after the filling process in a further operation impairs the appearance of the window profile.
  • the GB 2 434 395 A discloses a method for improving the thermal insulation of a hollow chamber profile with the features described above. Furthermore, at this point is still on the pamphlets EP 2 031 169 A2 . EP 1 693 546 A1 . DE 32 24 891 A1 and DE 200 01 889 U1 pointed, in which various window or door hollow chamber profiles are disclosed with inserted profiles or heat-insulating measures.
  • the invention has for its object to provide a method for improving the thermal insulation of a hollow chamber profile, which avoids the aforementioned disadvantages and at the same time ensures a sustainable improvement of the thermal insulation properties.
  • the object is achieved in that the jacket profile is made with an undersize with respect to the surrounding the shell profile hollow chamber.
  • the insulating profile is inserted after the extrusion of the hollow chamber profile in the hollow chambers.
  • This allows direct cooling of the produced Dämmprofils from the outside and thus leads to a further procedural simplification.
  • the insulation profile according to the invention is also characterized in that it compared to known Dämmprofilen (see. DE 43 31 816 A1 ) is significantly more robust, so that when handling it, especially when inserted into the hollow chamber profile, even with large profile lengths of eg 4 meters and more no risk of breakage exists.
  • the hollow chamber profile and / or the skirt profile are preferably made of plastic, z. B. PVC.
  • the clearance between the insulating profile and the hollow chamber is then at least 0.5 mm, preferably at least 1 mm.
  • the insulating profile is expediently fixed via at least one opening in the hollow chamber wall in the hollow chamber, preferably by means of a separate binder.
  • a binder for example, adhesive and / or foam material can be used.
  • mechanical binders such. B. tension springs, rivets, Screws, pins, nails or the like.
  • the fixation can also be effected by welding the casing profile to the hollow chamber wall.
  • the dimensioning of the casing profile and the hollow chamber surrounding the casing profile are coordinated with one another in such a way that, in addition to its insulating function, the insulation profile also has a mechanical reinforcing function.
  • the jacket profile is usually dimensioned so that - analogous to the insertion of a metal reinforcement, such as in the DE 43 31 816 A1 described - an insertion of the insulating profile in the hollow chamber on the one hand is possible, on the other hand, but no significant play between the insulating profile and corresponding Hohlcrowandung is present, so that the forces acting on the hollow chamber profile forces are transmitted to the insulation profile.
  • the jacket profile for this purpose is partially or completely made of fiber-reinforced plastics, for example PVC.
  • the hollow chamber profile is partially or completely made of fiber-reinforced plastic, eg PVC.
  • mineral (for example glass) and / or carbon and / or aramid and / or basalt fibers can be used as reinforcing fibers.
  • the foaming of the jacket profile is carried out according to the invention due to the already described, comparatively low demands on the foaming process (relatively simple accordinglySystemumende geometry, no high demands on the appearance of the insulating profile) as online foaming.
  • the foam material can be applied, for example, via the extrusion die for the jacket profile (for example by means of a lance) or else in the extrusion line, for example over the opened profile and, if necessary, again after foaming.
  • the wall of the jacket profile expediently has at least one opening through which the foam material is introduced into the jacket profile. This opening can be closed later if necessary.
  • the jacket profile can be provided with at least one, for example, continuous, longitudinal slot through which the foam material in the shell profile introduced and is suitably closed after the introduction of the foam material in the shell profile, for example by means of a weld forming a weld (with or without filler material) or alternatively by adhesive or a closure element.
  • the jacket profile is first filled with the foam material before it is folded into a closed profile.
  • the shell profile for this purpose have one or more locking elements, which ensure the secure closure of the profile after the introduction of the foam.
  • a film hinge may be provided on the skirt profile.
  • the foam material is preferably made of an organic material with low thermal conductivity, in particular polystyrene, polyvinyl chloride, polyethylene, polyurethane or mixtures of two or more of said materials.
  • the thermal conductivity of the foam material A is preferably 0.02 to 0.04 W / mK. This ensures a lasting improvement in the thermal insulation properties of the entire hollow chamber profile.
  • polyurethane the two components polyisocyanate and polyol are introduced into the shell profile, wherein the reaction mixture is suitably adjusted so that the reaction begins after introduction of the foam material in the shell profile. Due to the chemical reaction it comes to the desired foaming process and thus to a foaming of the shell profile.
  • FIGURE shows a heat-insulated hollow chamber profile according to the invention in the cross-sectional representation.
  • the FIGURE shows a window or door hollow-chamber profile 1 with a plurality of hollow chambers 2, 2 ', 2 ".
  • an insulating profile 3 ', 3 " is introduced, the two insulating profiles 3', 3 "each have a dimensionally stable, designed as a hollow profile casing profile 4 ', 4", which is foamed with foam material 5.
  • the shaping of the hollow chamber profile 1. The improvement of the thermal insulation is carried out with Help of the two separate insulation profiles 3 ', 3 ".
  • the two casing profiles 4 ', 4 "of the insulating profiles 3', 3" are first produced by way of further extrusion processes. Then the jacket profiles 4 ', 4 "are foamed with foam material 5. After the subsequent completion of the insulating profiles 3', 3" (eg cooling, cutting etc.), these insulating profiles 3 ', 3 "are inserted into the respectively assigned hollow chambers 2', 2 "of the hollow chamber profile 1 is inserted.
  • the left insulating profile 3 ' is fixed via a plurality of openings 6 in the corresponding hollow chamber wall by means of adhesive 7 in the hollow chamber 2'.
  • the right jacket profile 4 " consists of fiber-reinforced plastic (eg PVC) and is dimensioned so that it can just be easily inserted into the corresponding hollow chamber 2", so this no significant game has.
  • the hollow chamber profile 2 thus requires no Stahlarm ist.
  • the hollow chamber profile itself 1 consists in usually made of unreinforced PVC, can be made of fiber-reinforced PVC to further increase the mechanical strength but also, for example, in certain areas.
  • the wall thickness d of the casing profiles 4 ', 4 is preferably at least 1 mm.
  • the foam material 5 is made of polyurethane.
  • the two components polyisocyanate and polyol are applied via a lance through the longitudinal slot of a jacket profile.
  • the reaction mixture is adjusted so that the reaction begins only after introduction of the foam material 5 into the jacket profiles 4 ', 4 ".
  • the chemical reaction leads to the desired foaming process and thus to a preferably complete foaming of the jacket profiles 4', 4".
