Description

Verfahren zur Verbesserung der Wärmedämmung eines Hohlkammerprofils  Method for improving the thermal insulation of a hollow chamber profile
sowie Hohlkammerprofil  as well as hollow chamber profile
Die Erfindung betrifft ein Verfahren zur Verbesserung der Wärmedämmung eines Hohlkammerprofils, insbesondere eines Fenster- oder Tür-Hohlkammerprofils, wobei im Wege eines Extrusionsverfahrens die Formgebung des mindestens eine Hohlkammer aufweisenden Hohlkammerprofils erfolgt und wobei die Verbesserung der Wärmedämmung mit Hilfe mindestens eines separaten Dämmprofils erfolgt. Ein derartiges Verfahren ist beispielsweise aus der DE 43 31 816 A1 bekannt. Aufgrund der im Zuge des Klimawandels immer anspruchsvoller werdenden C02-Einsparziele besteht ein großer Bedarf hinsichtlich einer nachhaltigen Weiterentwicklung der Wärmedämmeigenschaften von Bauelementen, insbesondere Fenster- oder Türprofilen. Bei dem in der DE 43 31 816 A1 beschriebenen Verfahren wird ein Kunststoff-Schaumstreifen an einer Stahlar- mierung befestigt und gemeinsam mit dieser in eine Hohlkammer des Tür- bzw. Fensterprofils eingeschoben. Aufgrund der Stahlarmierung sind die Wärmedämmeigenschaften des beschriebenen Profils vergleichsweise schlecht, woran auch die Einbringung des Schaumstreifens nichts grundsätzlich ändern kann. Darüber hinaus besteht bei dem beschriebenen Stand der Technik auch die Problematik, dass das Schaummaterial eine ver- gleichsweise empfindliche Oberfläche aufweist, welche beim Einschieben des Profils in das Hohlkammerprofil beschädigt werden kann, so dass ungewünschte Schaumkrümel entstehen. Ferner ist auch zu berücksichtigen, dass der Schaumstreifen - sofern er nicht an einer Stahlarmierung befestigt ist - aufgrund seiner großen Länge relativ leicht zerbrechen kann, wodurch sich das Handling erschwert. Bei einer nachträglichen alleinigen Einbringung von Dämmprofilen in Hohlkammerprofile besteht daher die grundsätzliche Problematik, dass die Dämmprofile nur eine relativ kurze Länge besitzen dürfen (ca. 1-2 m), weil das Einbringen längerer Profile zum Brechen derselben führt. Um die Wärmedämmeigenschaften zu verbessern, ist es im Stand der Technik ebenfalls bekannt, ein Tür- bzw. Fenster-Hohlkammerprofil direkt auszuschäumen. Derartige, unmittelbar in den Extrusionsprozess integrierte Verfahren sind z.B. aus WO 2009/06286 A1 oder DE 197 31 163 A1 bekannt. Bei diesen Verfahren ist nachteilig, dass die prozesstechnische Handhabung der direkten Ausschäumung vergleichweise aufwändig ist. Insbesondere beim Einsatz von PUR-Schaum besteht hier die anspruchsvolle Aufgabe, einen Verzug des Hohlkammerprofils während des Schäumvorgangs zu verhindern, da dieser eine große mechanische Belastung der Hohlkammerwandungen verursachen kann. The invention relates to a method for improving the thermal insulation of a hollow chamber profile, in particular a window or door hollow chamber profile, wherein by means of an extrusion process, the shaping of the at least one hollow chamber having hollow chamber profile and wherein the improvement of the thermal insulation using at least one separate insulation profile. Such a method is known for example from DE 43 31 816 A1. Due to the increasingly demanding C0 2 savings targets in the course 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. In the method described in DE 43 31 816 A1, a plastic foam strip is fastened to a steel armature and, together with the latter, inserted into 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. In addition, there is also the problem in the prior art described that the foam material has a comparatively sensitive surface, which can be damaged when the profile is inserted into the hollow chamber profile, so that undesired foam crumbs arise. Furthermore, it should also be considered that the foam strip - if it is not attached to a Stahlarmierung - relatively easy to break because of its large length, making handling difficult. In a subsequent sole contribution of Dämmprofilen in hollow chamber profiles, therefore, there is the fundamental problem that 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. In order to improve the thermal insulation properties, it is likewise known in the prior art to foam out a door or window hollow-chamber profile directly. Such processes, which are directly integrated in the extrusion process, are known, for example, from WO 2009/06286 A1 or DE 197 31 163 A1. In these methods, it is disadvantageous that the process-technical handling of the direct foaming is comparatively complicated. In particular, when using PUR foam here is the challenging task of preventing distortion of the hollow chamber profile during the foaming process, since this can cause a large mechanical load on the hollow chamber walls.
Daneben gibt es auch Schäumverfahren, bei denen die Ausschäumung des In addition, there are also foaming processes in which the foaming of the
Extrusionsprofils nach dem Extrusionsvorgang erfolgt. Die DE 100 35 649 A1 zeigt ein Verfahren zur Ausschäumung von Fensterprofilen, bei dem nach der Profilerzeugung über einen durchgehenden Schlitz in der Profilwandung eine Einbringung von Schaummaterial mittels einer feststehenden Lanze, durch die das Schaummaterial strömt, erfolgt. Bei diesem Verfahren ist jedoch nachteilig, dass der nach dem Befüllvorgang in einem weiteren Arbeitsgang zu verschließende Schlitz das Erscheinungsbild des Fensterprofils beeinträchtigt. Vor diesem Hintergrund liegt der Erfindung die Aufgabe zugrunde, ein Verfahren zur Verbesserung der Wärmedämmung eines Hohlkammerprofils anzugeben, welches die vorgenannten Nachteile vermeidet und gleichzeitig eine nachhaltige Verbesserung der Wärmedämmeigenschaften sicherstellt. Ausgehend von einem Verfahren mit den eingangs beschriebenen Merkmalen wird die Aufgabe erfindungsgemäß dadurch gelöst, dass im Wege eines Extrusionsverfahrens ein Mantelprofil des Dämmprofils hergestellt wird, wobei das Mantelprofil mit Schaummaterial ausgeschäumt wird und wobei das so hergestellte Dämmprofil in eine Hohlkammer eingebracht wird. Erfindungsgemäß erfolgt somit eine vollständige Entkoppelung des Extrusion profile after the extrusion process takes place. DE 100 35 649 A1 shows a method for foaming window profiles, in which after profiling via a continuous slot in the profile wall, an introduction of foam material by means of a fixed lance, through which the foam material flows takes place. However, 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. Against this background, 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 thermal insulation properties. Starting from a method having the features described in the introduction, the object is achieved in that a jacket profile of the insulating profile is produced by way of an extrusion process, wherein the shell profile is foamed with foam material and wherein the insulating profile thus prepared is introduced into a hollow chamber. According to the invention thus takes place a complete decoupling of
Schäumverfahrens von der Herstellung des eigentlichen Hohlkammerprofils, so dass die Herstellung des Hohlkammerprofils durch die Ausschäumung prozesstechnisch nicht erschwert wird. Die Geometrie des erfindungsgemäß auszuschäumenden, zweckmäßigerweise formstabilen Mantelprofils ist deutlich weniger komplex als die des Hohlkammerprofils, wodurch sich bereits eine erhebliche Erleichterung der prozesstechnischen Handha- bung des Schäumvorgangs ergibt. Darüber hinaus werden an das als Hohlprofil ausgebil- dete Mantelprofil keine hohen Anforderungen hinsichtlich des Erscheinungsbildes nach dem Befüllvorgang gestellt, da dieses im fertig verbauten Hohlkammerprofil nicht sichtbar ist. Von daher ist es unproblematisch, die Ausschäumung des Mantelprofils über sichtbare Öffnungen in der Mantelprofilwandung, wie z. B. Löcher, Schlitze und dergleichen, zu er- leichtern. Vorzugsweise wird das Dämmprofil nach der Extrusion des Hohlkammerprofils in die Hohlkammer eingeschoben. Dies erlaubt eine Direktkühlung des hergestellten Dämmprofils von außen und führt damit zu einer weiteren prozesstechnischen Vereinfachung. Das erfindungsgemäße Dämmprofil zeichnet sich auch dadurch aus, dass es im Vergleich zu bekannten Dämmprofilen (vergl. DE 43 31 816 A1) deutlich robuster ist, so dass bei dessen Handhabung, insbesondere beim Einschieben in das Hohlkammerprofil, auch bei großen Profillängen von z.B. 4 Metern und mehr keine Bruchgefahr besteht. Das Hohlkammerprofil und/oder das Mantelprofil bestehen vorzugsweise aus Kunststoff, z. B. PVC. Foaming process of the production of the actual hollow chamber profile, so that the production of the hollow chamber profile is not complicated by the foaming process technology. The geometry of the suitably dimensionally stable casing profile to be foamed according to the invention is significantly less complex than that of the hollow chamber profile, which already results in a considerable facilitation of the process engineering handling of the foaming process. In addition, the profile formed as a hollow profile Dete coat profile made no high demands on the appearance after the filling, as this is not visible in the finished installed hollow chamber profile. Therefore, it is not a problem, the foaming of the shell profile visible through openings in the Mantelprofilwandung such. As holes, slots and the like, to facilitate. Preferably, the insulating profile is inserted after the extrusion of the hollow chamber profile in the hollow chamber. 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 by the fact that it is much more robust compared to known insulating profiles (see, DE 43 31 816 A1), so that during its handling, especially when inserted into the hollow chamber profile, even with long profile lengths of eg 4 meters and more no danger of breakage exists. The hollow chamber profile and / or the skirt profile are preferably made of plastic, z. B. PVC.
Im Rahmen der Erfindung liegt es, dass das Mantelprofil mit einem Untermaß gegenüber der das Mantelprofil umgebenden Hohlkammer gefertigt wird. Vorzugsweise beträgt das Spiel zwischen Dämmprofil und Hohlkammer dann mindestens 0,5 mm, vorzugsweise mindestens 1 mm. Dies erlaubt ein besonders leichtes Einschieben des Mantelprofils in die Hohlkammer. Im Falle eines vorliegenden Untermaßes wird das Dämmprofil zweckmäßigerweise über mindestens eine Öffnung in der Hohlkammerwandung in der Hohlkammer fixiert, vorzugsweise mittels eines separaten Bindemittels. Als Bindemittel kann beispielsweise Klebstoff und/oder Schaummaterial verwendet werden. Denkbar sind jedoch aber auch mechanische Bindemittel, wie z. B. Spannfedern, Nieten, Schrauben, Stiften, Nägeln oder dergleichen. Alternativ kann die Fixierung auch über ein Verschweißen des Mantelprofils mit der Hohlkammerwandung erfolgen. In the context of the invention it is that the casing profile is made with an undersize with respect to the hollow chamber surrounding the casing profile. Preferably, the clearance between the insulating profile and the hollow chamber is then at least 0.5 mm, preferably at least 1 mm. This allows a particularly easy insertion of the jacket profile in the hollow chamber. In the case of an existing undersize 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. As a binder, for example, adhesive and / or foam material can be used. However, it is also conceivable mechanical binders such. As tension springs, rivets, screws, pins, nails or the like. Alternatively, the fixation can also be effected by welding the casing profile to the hollow chamber wall.
Im Rahmen der Erfindung liegt es insbesondere aber auch, dass die Bemessung des Mantelprofils und der das Mantelprofil umgebenden Hohlkammer derart aufeinander abgestimmt sind, dass das Dämmprofil neben seiner Dämmfunktion zusätzlich auch eine mechanische Verstärkungsfunktion besitzt. In diesem Fall wird das Mantelprofil in der Regel so dimensioniert, dass - analog zum Einschieben einer Metallarmierung, wie beispielsweise in der DE 43 31 816 A1 beschrieben - ein Einschieben des Dämmprofils in die Hohlkammer einerseits möglich ist, andererseits aber kein nennenswertes Spiel zwischen Dämmprofil und entsprechender Hohlkammerwandung vorliegt, so dass die auf das Hohlkammerprofil einwirkenden Kräfte auf das Dämmprofil übertragen werden. Durch diese Doppelfunktion des Dämmprofils wird eine vergleichsweise einfache und daher kosten- günstige Herstellung eines besonders gut wärmegedämmten Hohlkammerprofils sichergestellt, da die im Stand der Technik bekannte, hinsichtlich der Wärmedämmung ungünstige Stahlarmierung durch eine die Wärmedämmeigenschaften sogar deutlich verbessernde Armierung in Form des erfindungsgemäßen Dämmprofils ersetzt wird. Zweckmäßigerweise besteht das Mantelprofil hierzu bereichsweise oder vollständig aus faserverstärktem Kunststoff, zB PVC. Im Rahmen der Erfindung liegt es aber auch, dass alternativ oder auch zusätzlich das Hohlkammerprofil bereichsweise oder vollständig aus faserverstärktem Kunststoff, zB PVC, besteht. Als Verstärkungsfasern können insbesondere Mineral- (zum Beispiel Glas-) und / oder Karbon- und / oder Aramid- und / oder Basaltfasern verwendet wer- den. In the context of the invention, it is also especially true that 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. In this case, the jacket profile is usually dimensioned so that - analogous to the insertion of a metal reinforcement, as described for example in DE 43 31 816 A1 - insertion of the Dämmprofils in the hollow chamber on the one hand, on the other hand, but no significant game between insulation profile and corresponding hollow chamber wall is present, so that the forces acting on the hollow chamber profile forces are transmitted to the insulating profile. This double function of the insulating profile makes a comparatively simple and therefore cost-effective favorable production of a particularly well-insulated hollow chamber profile ensured because the known in the prior art, in terms of thermal insulation unfavorable Stahlarmierung is replaced by a thermal insulation properties even significantly improving reinforcement in the form of insulation profile according to the invention. For this purpose, the jacket profile expediently consists partly or completely of fiber-reinforced plastic, for example PVC. However, it is also within the scope of the invention that, alternatively or additionally, the hollow chamber profile is partially or completely made of fiber-reinforced plastic, eg PVC. In particular mineral (for example glass) and / or carbon and / or aramid and / or basalt fibers can be used as reinforcing fibers.
Die Ausschäumung des Mantelprofils kann auf verschiedene Arten erfolgen, wobei aufgrund der bereits beschriebenen, vergleichsweise niedrigen Anforderungen an den The foaming of the shell profile can be done in various ways, due to the already described, comparatively low demands on the
Schäumprozess (relativ einfache auszuschäumende Geometrie, keine hohen Anforderun- gen an Erscheinungsbild des Dämmprofils) vorzugsweise eine Online-Ausschäumung erfolgt. Das Schaummaterial kann beispielsweise über die Extrusionsdüse für das Mantelprofil (z.B. mittels einer Lanze) oder aber auch in der Extrusionsstrecke, z.B. über das geöffnete und ggf. nach der Ausschäumung wieder zu verschließende Profil, appliziert werden. Zweckmäßigerweise weist die Wandung des Mantelprofils mindestens eine Öffnung auf, durch die das Schaummaterial in das Mantelprofil eingebracht wird. Diese Öffnung kann im Bedarfsfall nachträglich verschlossen werden. So kann beispielsweise das Mantelprofil mit mindestens einem, beispielsweise durchgehenden, Längsschlitz versehen werden, durch den das Schaummaterial in das Mantelprofil eingebracht und der zweckmäßigerweise nach der Einbringung des Schaummaterials in das Mantelprofil verschlossen wird, beispielsweise mittels eines eine Schweißnaht bildenden Schweißvorgangs (mit oder ohne Zusatzwerkstoff) oder alternativ durch Klebstoff bzw. ein Verschlusselement. Foaming process (relatively simple auszuschäumende geometry, no high demands on the appearance of the insulating profile) preferably an online foaming takes place. The foam material can be conveyed, for example, via the extrusion profile for the jacket profile (for example by means of a lance) or else in the extrusion line, e.g. be applied over the open and possibly after the foaming again to be closed profile. 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. Thus, for example, the jacket profile can be provided with at least one longitudinal slot, for example, through which the foam material is introduced into the jacket profile and which is expediently closed after the introduction of the foam material into the jacket profile, for example by means of a welding operation forming a weld (with or without additional material) ) or alternatively by adhesive or a closure element.
Im Rahmen der Erfindung liegt es auch, dass das Mantelprofil zunächst mit dem Schaummaterial befüllt wird, bevor es zu einem geschlossenen Profil zusammengeklappt wird. So kann beispielsweise das Mantelprofil hierzu über ein oder mehrere Rastelemente verfügen, welche den sicheren Verschluss des Profils nach der Einbringung des Schaums sicherstellen. Um eine entsprechende Beweglichkeit der zuzuklappenden Wandung sicherzustellen, kann am Mantelprofil ein Filmscharnier vorgesehen sein. Das Schaummaterial besteht vorzugsweise aus einem organischen Material mit niedriger Wärmeleitfähigkeit, insbesondere Polystyrol, Polyvinylchlorid, Polyethylen, Polyurethan oder Mischungen zweier oder mehr der genannten Materialien. Die Wärmeleitfähigkeit des Schaummaterials λ beträgt vorzugsweise 0,02 bis 0,04 W/mK. Dies gewährleistet eine nachhaltige Verbesserung der Wärmedämmeigenschaften des gesamten Hohlkammerprofils. Bei Verwendung von Polyurethan werden die beiden Komponenten Polyisocyanat und Polyol in das Mantelprofil eingebracht, wobei das Reaktionsgemisch zweckmäßigerweise so eingestellt ist, dass die Reaktion erst nach Einbringung des Schaummaterials in das Mantelprofil beginnt. Aufgrund der chemischen Reaktion kommt es zum gewünschten Schäumvorgang und damit zu einer Ausschäumung des Mantelprofils. In the context of the invention, it is also the case that the jacket profile is first filled with the foam material before it is folded into a closed profile. For example, 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. To ensure appropriate mobility of the zuklappenden wall, 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 λ 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. When using 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.
Gegenstand der Erfindung ist ferner ein Hohlkammerprofil gemäß Anspruch 10. The invention further relates to a hollow chamber profile according to claim 10.
Im Folgenden wird die Erfindung anhand einer lediglich ein Ausführungsbeispiel darstellen- den Zeichnung ausführlich erläutert. Die einzige Figur zeigt ein erfindungsgemäß wärmegedämmtes Hohlkammerprofil in der Querschnittdarstellung. In the following the invention will be explained in detail with reference to a drawing showing only one exemplary embodiment. The single FIGURE shows a heat-insulated hollow chamber profile according to the invention in the cross-sectional representation.
Die Figur zeigt ein Fenster- bzw. Tür-Hohlkammerprofil 1 mit mehreren Hohlkammern 2, 2', 2". In zwei der Hohlkammern 2', 2" ist jeweils ein Dämmprofil 3', 3" eingebracht. Die beiden Dämmprofile 3', 3" weisen jeweils ein formstabiles, als Hohlprofil ausgebildetes Mantelprofil 4', 4" auf, welches mit Schaummaterial 5 ausgeschäumt ist. Zur Herstellung der in der Figur dargestellten Vorrichtung erfolgt im Wege eines ersten Extrusionsverfahrens die Formgebung des Hohlkammerprofils 1. Die Verbesserung der Wärmedämmung erfolgt mit Hilfe der zwei separaten Dämmprofile 3', 3". Hierzu werden im Wege weiterer The FIGURE shows a window or door hollow-chamber profile 1 with a plurality of hollow chambers 2, 2 ', 2 ".In each of the hollow chambers 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. To produce the device shown in the figure by means of a first extrusion process, 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 ". This will be done by way of further
Extrusionsverfahren zunächst die beiden Mantelprofile 4', 4" der Dämmprofile 3', 3" hergestellt. Daraufhin werden die Mantelprofile 4', 4" mit Schaummaterial 5 ausgeschäumt. Nach der anschließenden Fertigstellung der Dämmprofile 3', 3" (zB Abkühlen, Ablängen etc.) werden diese Dämmprofile 3', 3" in die jeweils zugeordneten Hohlkammern 2', 2" des Hohlkammerprofils 1 eingeschoben. Das linke Mantelprofil 4' besteht aus unverstärktem Kunststoff, z.B. PVC. Wie der Figur zu entnehmen ist, ist dieses Mantelprofil 4' mit einem Untermaß gegenüber der das Mantelprofil 4' umgebenden Hohlkammer 2' gefertigt. Im Ausführungsbeispiel beträgt das Spiel s = 1 mm. Das linke Dämmprofil 3' ist über mehrere Öffnungen 6 in der entsprechenden Hohlkammerwandung mittels Klebstoff 7 in der Hohlkammer 2' fixiert. Das rechte Mantelprofil 4" besteht hingegen aus faserverstärktem Kunst- stoff (z.B. PVC) und ist so dimensioniert, dass es gerade problemlos in die entsprechende Hohlkammer 2" eingeschoben werden kann, gegenüber dieser also kein nennenswertes Spiel besitzt. Dies hat zur Folge, dass auf das Hohlkammerprofil 2" einwirkende Kräfte auf das entsprechende Dämmprofil 3' übertragen werden können, so dass dieses neben seiner Dämmfunktion zusätzlich eine mechanische Verstärkungsfunktion wahrnimmt. Das darge- stellte Hohlkammerprofil 1 benötigt somit keine Stahlarmierung. Das Hohlkammerprofil selbst 1 besteht in der Regel aus unverstärktem PVC, kann zur weiteren Erhöhung der mechanischen Belastbarkeit aber auch, z.B. bereichsweise, aus faserverstärktem PVC bestehen. Die Wandstärke d der Mantelprofile 4', 4" beträgt vorzugsweise mindestens 1 mm. Wie der Figur zu entnehmen ist, weisen die beiden Mantelprofile 4', 4" jeweils einen in Extrusionsrichtung ausgerichteten Längsschlitz 8', 8" auf, der zur Einbringung des Extrusion process, first, the two sheath profiles 4 ', 4 "of the insulating profiles 3', 3" produced. 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 jacket profile 4 'consists of unreinforced plastic, eg PVC. As can be seen from the figure, this casing profile 4 'is made with an undersize with respect to the casing profile 4' surrounding hollow chamber 2 '. In the embodiment, the game s = 1 mm. 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 ", on the other hand, is made of fiber-reinforced plastic (eg PVC) and is dimensioned so that it can be easily inserted into the corresponding one As a result, forces acting on the hollow chamber profile 2 "can be transmitted to the corresponding insulating profile 3 'so that, in addition to its insulating function, it also performs a mechanical reinforcement function. The illustrated hollow chamber profile 1 thus requires no steel reinforcement. The hollow chamber profile itself 1 is usually made of unreinforced PVC, but may also consist, for example, of fiber-reinforced PVC to further increase the mechanical strength. The wall thickness d of the casing profiles 4 ', 4 "is preferably at least 1 mm. As can be seen from the figure, the two casing profiles 4', 4" each have a longitudinal slot 8 ', 8 "aligned in the direction of extrusion
Schaummaterials 5 in das jeweilige Mantelprofil 4', 4" dient. Die beiden Längsschlitze 8', 8" werden nach der Einbringung des Schaummaterials 5 in die jeweiligen Mantelprofile verschlossen, beispielsweise mittels eines eine Schweißnaht 9', 9" bildenden Schweißvor- gangs (mit oder ohne Zusatzwerkstoff) oder alternativ durch Klebstoff bzw. ein Verschlusselement. The two longitudinal slots 8 ', 8 "are closed after the introduction of the foam material 5 into the respective jacket profiles, for example by means of a welding operation (forming a weld 9', 9") or without filler material) or alternatively by adhesive or a closure element.
Das Schaummaterial 5 besteht aus Polyurethan. Beim Ausschäumvorgang werden die beiden Komponenten Polyisocyanat und Polyol über eine Lanze durch den Längsschlitz eines Mantelprofils appliziert. Das Reaktionsgemisch ist so eingestellt, dass die Reaktion erst nach Einbringung des Schaummaterials 5 in die Mantelprofile 4', 4" beginnt. Aufgrund der chemischen Reaktion kommt es zum gewünschten Schäumvorgang und damit zu einer vorzugsweise vollständigen Ausschäumung der Mantelprofile 4', 4". The foam material 5 is made of polyurethane. During the foaming process, 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".
