Description

Die Erfindung betrifft ein Verfahren zur Einbringung von Dämmmaterial in Hohlkammerprofile, insbesondere Fenster- oder Tür-Hohlkammerprofile,

  • wobei im Wege eines Extrusionsverfahrens die Formgebung des mindestens eine Hohlkammer aufweisenden Hohlkammerprofils erfolgt,
  • wobei danach mindestens ein Dämmprofil in mindestes eine Hohlkammer eingeschoben wird und
  • wobei das Dämmprofil gegenüber der Hohlkammer ein Untermaß besitzt und über mindestens eine Öffnung in der Hohlkammerwandung in der Hohlkammer fixiert wird.
The invention relates to a method for introducing insulating material into hollow chamber profiles, in particular window or door hollow chamber profiles,
  • wherein by means of an extrusion process, the shaping of the at least one hollow chamber having hollow chamber profile,
  • after which at least one insulating profile is inserted into at least one hollow chamber and
  • wherein the insulating profile relative to the hollow chamber has an undersize and is fixed via at least one opening in the hollow chamber wall in the hollow chamber.

Ein Verfahren zur Einbringung von Dämmmaterial in Hohlkammerprofile ist beispielsweise aus der DE 43 31 816 A1 bekannt. Bei dem bekannten Verfahren wird ein Schaumprofil auf ein Verstärkungsprofil aus Metall aufgeklebt und gemeinsam mit diesem in eine Hohlkammer des Hohlkammerprofils eingeschoben. Aufgrund der erforderlichen Metallarmierung sind die Wärmedämmeigenschaften dieses bekannten Profils insgesamt begrenzt.A method for introducing insulation in hollow chamber profiles, for example, from DE 43 31 816 A1 known. In the known method, a foam profile is glued to a reinforcing profile made of metal and inserted together with this in a hollow chamber of the hollow chamber profile. Due to the required metal reinforcement, the thermal insulation properties of this known profile are limited overall.

Im Stand der Technik ist es ebenfalls bekannt, Fenster- oder Tür-Hohlkammerprofile zwecks Verbesserung der Wärmedämmung nachträglich mit einem Schaummaterial auszufüllen, wie beispielsweise in der DE 100 35 649 A1 beschrieben. Darüber hinaus sind auch Verfahren bekannt, bei denen die Ausschäumung unmittelbar in die Extrusion des Hohlkammerprofils integriert ist (siehe z.B. WO 2009/062986 A1 oder DE 197 31 163 A1 ). Die Ausschäumung eines Hohlkammerprofils ist häufig verfahrenstechnisch vergleichsweise aufwendig und die damit erzielbaren Verbesserungen der Wärmedämmung sind meistens ebenfalls begrenzt, da die Ausschäumung oftmals nicht vollständig gewährleistet werden kann.In the prior art, it is also known to later fill window or door hollow chamber profiles in order to improve the thermal insulation with a foam material, such as in the DE 100 35 649 A1 described. In addition, methods are known in which the foaming is integrated directly into the extrusion of the hollow chamber profile (see, eg WO 2009/062986 A1 or DE 197 31 163 A1 ). The foaming of a hollow chamber profile is often procedurally relatively expensive and thus achievable improvements in heat insulation are mostly also limited, since the foaming often can not be fully guaranteed.

Bei der nachträglichen Einbringung von Dämmprofilen in Hohlkammerprofile besteht die Problematik, dass die eingebrachten Dämmprofile nur eine relativ kurze Länge besitzen dürfen (ca. 1-2 m), weil das Einbringen längerer Profile zum Brechen derselben führt. Darüber hinaus sind i.d.R. nur organische Dämmstoffe als Material für das Dämmprofil verwendbar, da anorganische Dämmstoffe zumeist nur eine geringe mechanische Stabilität aufweisen. Organische Dämmstoffe haben jedoch häufig schlechtere Wärmedämmeigenschaften als optimierte anorganische Dämmstoffe.In the subsequent introduction of Dämmprofilen in hollow chamber profiles, the problem is that the introduced Dämmprofile 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 addition, i.d.R. Only organic insulation materials can be used as a material for the insulation profile, since inorganic insulation materials usually have only a low mechanical stability. However, organic insulating materials often have poorer thermal insulation properties than optimized inorganic insulation materials.

Die US 2009/178361 A1 offenbart ein Verfahren mit den eingangs beschriebenen Merkmalen. Als Einschubprofil kommt hier eine Holzleiste zum Einsatz, die mittels einer Schraube im Hohlkammerprofil fixiert wird. Aus der DE 20 2006 005 098 U1 sowie der DE 20 2009 016 935 U1 sind ebenfalls Fenster- bzw. Tür-Hohlkammerprofile mit eingeschobenen Profilen bekannt.The US 2009/178361 A1 discloses a method with the features described above. As a slide-in profile here is a wooden strip used, which is fixed by means of a screw in the hollow section. From the DE 20 2006 005 098 U1 as well as the DE 20 2009 016 935 U1 are also window or door hollow chamber profiles with inserted profiles known.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zur Einbringung von Dämmprofilen in Hohlkammerprofile anzugeben, welches eine lediglich geringe mechanische Belastung der Dämmprofile während des Einschubvorgangs sicherstellt.The invention has for its object to provide a method for introducing Dämmprofilen in hollow sections, which ensures only a small mechanical load on the insulating profiles during the insertion process.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 gelöst.This object is solved by the features of claim 1.

Erfindungsgemäß beruht die Fixierung nicht - wie üblich - auf einer Einklemmung des Dämmprofils in der Hohlkammer aufgrund einer entsprechenden Bemaßung des Dämmprofils, sondern stattdessen wird bewusst ein Spiel zwischen dem Dämmprofil und der Hohlkammerwandung vorgesehen. Dies erlaubt ein sehr einfaches Einschieben des Dämmprofils in die Hohlkammer, welches mit einer entsprechend sehr geringen mechanischen Beanspruchung des Dämmprofils beim Einschubvorgang einhergeht. Die Fixierung des Dämmprofils in der Hohlkammer erfolgt über eine in der Regel quer, insbesondere senkrecht, zur Extrusionsrichtung ausgerichteten Öffnung in der Hohlkammerwandung. Diese Öffnung wird vorzugsweise an einer Nicht-Sichtfläche des Hohlkammerprofils angebracht. Die Öffnung kann spanlos - zum Beispiel mechanisch oder thermisch - erzeugt werden, vorzugsweise über ein Stanzwerkzeug oder eine Laservorrichtung.According to the invention, the fixation is not based - as usual - on an entrapment of the insulating profile in the hollow chamber due to a corresponding dimensioning of the insulating profile, but instead a clearance between the insulating profile and the hollow chamber wall is deliberately provided. This allows a very simple insertion of the insulating profile in the hollow chamber, which is accompanied by a correspondingly very low mechanical stress of the insulating profile during insertion. The fixation of the insulating profile in the hollow chamber via a generally transversely, in particular perpendicular, aligned to the extrusion direction opening in the hollow chamber wall. This opening is preferably attached to a non-visible surface of the hollow chamber profile. The opening can be produced without cutting, for example mechanically or thermally, preferably via a punching tool or a laser device.

Vorzugsweise beträgt das Spiel zwischen Dämmprofil und Hohlkammer mindestens 0,5 mm, beispielsweise mindestens 1 mm. Zweckmäßigerweise erfolgt die Fixierung des Dämmprofils in der Hohlkammer über einen Klebstoff oder Schaum. Das Bindemittel wird über die entsprechende Öffnung appliziert und stellt einen Stoff- und / oder Formschluss zwischen Dämmprofil und Hohlkammerwandung her. Im Rahmen der Erfindung liegt insbesondere auch die Verwendung eines Heißklebstoffes als Bindemittel. Die Minimierung der Anhaftfläche ist insbesondere bei der stofflichen Wiederverwertung vorteilhaft.Preferably, the clearance between the insulating profile and the hollow chamber is at least 0.5 mm, for example at least 1 mm. Conveniently, the fixing of the insulating profile in the hollow chamber via an adhesive or foam. The binder is applied via the corresponding opening and produces a material and / or positive connection between the insulating profile and the hollow chamber wall. In the context of the invention, in particular, the use of a hot melt adhesive as a binder. The minimization of the adhesion surface is particularly advantageous in material recycling.

Im Rahmen einer vorteilhaften Ausführungsvariante der Erfindung liegt es, dass mehrere, in Extrusionsrichtung zumindest im Wesentlichen gleichmäßig voneinander beabstandete Öffnungen vorgesehen werden, über die anschließend an den entsprechenden Stellen eine Fixierung des Dämmprofils erfolgt. So können beispielsweise in einem Abstand von ca. 0,5 bis 1 m, insbesondere 0,7 bis 0,8 m, Öffnungen in das Extrusionsprofil eingebracht werden.In the context of an advantageous embodiment variant of the invention, it is provided that a plurality of openings, which are at least substantially uniformly spaced from each other in the extrusion direction, are provided over the followed by fixation of the insulating profile at the appropriate places. Thus, for example, at a distance of about 0.5 to 1 m, in particular 0.7 to 0.8 m, openings are introduced into the extrusion profile.

Im Rahmen einer vorteilhaften Ausführungsvariante der Erfindung liegt es, dass die Fixierung über eine Bindemittel-Zwischenschicht erfolgt, die Hohlkammerwandung und Dämmprofil stoffschlüssig miteinander verbindet. Hierbei können Distanzstege am Dämmprofil und / oder an der entsprechenden Hohlkammerwandung vorgesehen sein, die einen entsprechenden Spalt sicherstellen, in die das Bindemittels zwecks Herstellung der Zwischenschicht eingebracht wirdIn the context of an advantageous embodiment of the invention, it is that the fixation via a binder intermediate layer takes place, the hollow chamber wall and insulation profile connects materially together. In this case, spacer webs may be provided on the insulating profile and / or on the corresponding hollow chamber wall, which ensure a corresponding gap into which the binder is introduced for the purpose of producing the intermediate layer

Alternativ hierzu oder aber auch ergänzend kann das Dämmprofil und / oder die Hohlkammerwandung einen Verteilerkanal aufweisen, der zur Verteilung des Bindemittels zwischen Dämmprofil und Hohlkammerwandung, insbesondere in Extrusionsrichtung, dient. Dieser Verteilerkanal kann beispielsweise eine nutartige Gestalt aufweisen und insbesondere im Querschnitt eine Schwalbenschwarz-Geometrie besitzen. Hierdurch ist neben dem Stoffschluss zusätzlich auch ein Formschluss zwischen Bindemittel und Dämmprofil bzw. Hohlkammerwandung sichergestellt.Alternatively, or in addition, the insulating profile and / or the hollow chamber wall may have a distribution channel, which serves to distribute the binder between the insulating profile and the hollow chamber wall, in particular in the extrusion direction. This distribution channel may for example have a groove-like shape and in particular have a dovetail geometry in cross section. As a result, in addition to the material connection in addition, a positive connection between the binder and insulation profile or Hohlkammerwandung ensured.

Das Dämmprofil kann aus einem organischen Schaummaterial mit niedriger Wärmleitfähigkeit, insbesondere Polystyrol, Polyvinylchlorid, Polyethylen, Polyurethan oder Mischungen zweier oder mehr der genannten Materialien bestehen. Im Rahmen der Erfindung liegt es insbesondere aber auch, dass das Dämmprofil aus einem, z.B. schaumförmigen, anorganischen Material besteht, wie beispielsweise Schaumglas oder einem nanoporösem Dichtstoff (z.B. VACUPOR® der Fa. Porextherm). Diese anorganischen Materialien, welche häufig eine vergleichsweise fragile Konsistenz besitzen, können aufgrund des erfindungsgemäßen nur mit sehr geringer mechanischer Belastung verbundenen Einschubvorgangs hervorragend eingesetzt werden und besitzen zum Teil deutlich bessere Wärmedämmeigenschaften als organische Materialien.The insulating profile may consist of an organic foam material with low thermal conductivity, in particular polystyrene, polyvinyl chloride, polyethylene, polyurethane or mixtures of two or more of said materials. In the context of the invention, however, it is in particular also the case that the insulating profile consists of a, e.g. foam-like inorganic material such as foam glass or a nanoporous sealant (e.g., VACUPOR® from Porextherm). These inorganic materials, which often have a comparatively fragile consistency, can be used excellently owing to the insertion process according to the invention which is only associated with very little mechanical stress, and in some cases have significantly better thermal insulation properties than organic materials.

Das Hohlkammerprofil kann bereichweise oder vollständig aus faserverstärktem Kunststoff bestehen, wobei als Verstärkungsmaterialien insbesondere Mineral- (z.B. Glas-) und / oder Karbon- und / oder Aramid- und / oder Basaltfasern verwendet werden können. Die Verstärkungsmaterialien können die bei Fenster- oder Tür-Hohlkammerprofilen üblicherweise erforderlichen Stahlarmierungen entbehrlich machen, wodurch sich der innere freie Profilhohlraum, der zur Befüllung mit Dämmmaterial genutzt werden kann, vergrößert. Die Verwendung von unverstärktem Kunststoffmaterial wird hierdurch jedoch selbstverständlich nicht ausgeschlossen.The hollow chamber profile may be made partially or completely of fiber-reinforced plastic, wherein as reinforcing materials in particular mineral (eg glass) and / or carbon and / or aramid and / or basalt fibers can be used. The reinforcing materials can make the steel reinforcements usually required for window or door hollow sections dispensable, thereby increasing the inner free profile cavity, which can be used for filling with insulating material increases. The usage Of course, this does not exclude unreinforced plastic material.

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 darstellenden Zeichnung ausführlich erläutert. Es zeigen schematisch:

In the following the invention will be explained in detail with reference to a drawing showing only one embodiment. They show schematically:
Fig. 1
An inventively produced hollow chamber profile in the quality representation and
Fig. 2
a further embodiment of the invention in one of Fig. 1 corresponding representation.

Fig. 1 zeigt ein Fenster- oder Tür-Hohlkammerprofil 1 aus Kunststoff, z.B. Hart-PVC. Dieses weist mehrere Hohlkammern 2,2' auf, wobei in eine Hohlkammer 2 ein Dämmprofil 3 eingeschoben ist. Das Dämmprofil 3 besitzt gegenüber der Hohlkammer 2 ein Untermaß und ist über mehrere Öffnungen 4 in der Hohlkammerwandung 8 in der Hohlkammer 2 fixiert, wobei das Spiel s zwischen Dämmprofil 3 und Hohlkammer 2 mindestens 0,5 mm beträgt. Bei der Herstellung erfolgt zunächst im Wege eines Extrusionsverfahrens die Formgebung des Hohlkammerprofils 1, wobei danach das Dämmprofil 3 in die Hohlkammer 2 eingeschoben wird. Anschließend erfolgt über die in Extrusionsrichtung gleichmäßig voneinander beabstandeten Öffnungen 4 (z.B. in einem Abstand von ca. 0,75 m) die Fixierung des Dämmprofils 3 in der Hohlkammer 2. Die Fixierung wird über ein separates Bindemittel 5 sicher gestellt, im Ausführungsbeispiel einen Heißklebstoff. Das Bindemittel 5 bildet eine Zwischenschicht, welche die Hohlkammerwandung 8 und das Dämmprofil 3 stoffschlüssig miteinander verbindet. Im Ausführungsbeispiel weist das Dämmprofil 3 in Längsrichtung verlaufende Distanzstege 6 auf, welche randseitig angeordnet sind. Diese gewährleisten eine Beabstandung von Dämmprofil 3 und Hohlkammerwandung 8 im Bereich der Öffnung 4, so dass der Heißkleber 5 in den hierdurch gebildeten Freiraum ungehindert einfließen und sich dann verfestigen kann. Alternativ können Distanzstege auch an der Hohlkammerwandung 8 an entsprechenden Stellen angeordnet sein. Die Öffnungen 4 sind senkrecht zur aus der Zeichenebene heraus zeigenden Extrusionsrichtung ausgerichtet. Der Fig.1 ist ferner zu entnehmen, dass an der (z.B. dem warmen Innenraum eines Gebäudes zugewandten) Innenseite des Dämmprofils 3 (rechts) eine strahlungsreflektierende Beschichtung 9 vorgesehen ist. Diese kann zum Beispiel im Wellenlängenbereich 9 - 11 x 10-6 m reflektierend sein. An der (z.B. der Außenumgebung zugewandten) Außenseite des Dämmprofils 3 (links) ist ein weitere Beschichtung 10 vorgesehen, welche eine geringe Emissivität besitzt, z.B. im Wellenlängenbereich 9 - 11 x 10-6 m. Fig. 1 shows a window or door hollow chamber profile 1 made of plastic, eg rigid PVC. This has a plurality of hollow chambers 2,2 ', wherein in a hollow chamber 2, an insulating profile 3 is inserted. The insulating profile 3 has an undersize with respect to the hollow chamber 2 and is fixed in the hollow chamber 2 via a plurality of openings 4 in the hollow chamber wall 8, the clearance s between the insulating profile 3 and the hollow chamber 2 being at least 0.5 mm. In the production, the shaping of the hollow chamber profile 1 takes place initially by means of an extrusion process, after which the insulating profile 3 is inserted into the hollow chamber 2. Subsequently, the fixing of the insulating profile 3 in the hollow chamber 2 takes place via the openings 4 which are uniformly spaced apart in the extrusion direction (eg at a distance of approximately 0.75 m). The fixation is ensured by means of a separate binder 5, in the exemplary embodiment a hot melt adhesive. The binder 5 forms an intermediate layer, which connects the hollow chamber wall 8 and the insulating profile 3 cohesively. In the exemplary embodiment, the insulating profile 3 extending in the longitudinal direction spacer webs 6, which are arranged on the edge side. These ensure a spacing of insulating profile 3 and hollow chamber wall 8 in the region of the opening 4, so that the hot melt adhesive 5 can flow freely into the free space formed thereby and then solidify. Alternatively, spacer webs can also be arranged on the hollow chamber wall 8 at corresponding locations. The openings 4 are aligned perpendicular to the extrusion direction pointing out of the plane of the drawing. Of the Fig.1 It can also be seen that at the (eg the warm interior of a building facing) inside of the insulating profile 3 (right) a radiation-reflective coating 9 is provided. This can be reflective, for example, in the wavelength range 9 - 11 x 10 -6 m. At the (outside, for example, the outer environment facing) outside of the insulating profile 3 (left), a further coating 10 is provided, which has a low emissivity, for example in the wavelength range 9 - 11 x 10 -6 m.

Bei dem Ausführungsbeispiel gemäß Fig. 2 weist das Dämmprofil 3 einen Verteilerkanal 7 auf, der zur Verteilung des Bindemittels 5 zwischen Dämmprofil 3 und Hohlkammerwandung 8 dient. Dieser besitzt im Ausführungsbeispiel eine nutartige, schwalbenschwanzförmige Gestalt. Hierdurch wird im verfestigten Zustand des auch hier eingesetzten Heißklebers 5 neben dem Stoffschluss zwischen Klebstoff 5 und Dämmprofil 3 bzw. Hohlkammerwandung 8 ein Formschluss zwischen dem erstarrten Klebstoffmaterial 5 und dem Dämmprofil 3 hergestellt.In the embodiment according to Fig. 2 the insulating profile 3 a distribution channel 7, which serves for the distribution of the binder 5 between the insulating profile 3 and 8 Hohlkammerwandung. This has in the exemplary embodiment a groove-like, dovetail-shaped. As a result, a positive connection between the solidified adhesive material 5 and the insulating profile 3 is produced in the solidified state of the hot-melt adhesive 5 used here in addition to the adhesive bond between the adhesive 5 and the insulating profile 3 or hollow chamber 8.

Das Dämmprofil 3 kann aus einem organischen Schaummaterial mit niedriger Wärmeleitfähigkeit bestehen, zum Beispiel Polystyrol, Polyvinylchlorid, Polyethylen oder Polyurethan. Alternativ kann das Dämmprofil 3 insbesondere aber auch aus einem anorganischen, beispielsweise ebenfalls schaumförmigen, Material bestehen. Das Hohlkammerprofil 1 besteht bereichsweise aus faserverstärktem Kunststoff, so dass eine Stahlarmierung im vorliegenden Fall entbehrlich ist. Hierdurch vergrößert sich der dem Dämmprofil 3 zur Verfügung stehende freie Raum in der Hohlkammer 2, so dass insgesamt besonders gute Dämmeigenschaften erzielt werden können.The insulating profile 3 may consist of an organic foam material with low thermal conductivity, for example polystyrene, polyvinyl chloride, polyethylene or polyurethane. Alternatively, the insulating profile 3 but in particular also consist of an inorganic, for example foam-like, material. The hollow chamber profile 1 is partially made of fiber-reinforced plastic, so that a Stahlarmierung is unnecessary in the present case. This increases the insulating profile 3 available free space in the hollow chamber 2, so that a total of particularly good insulation properties can be achieved.
