Description

Die vorliegende Erfindung betrifft ein Verfahren zur Herstellung eines wärmedämmenden Isolier- und Verbindungssteges für die Verbindung einer Außenschale und einer Innenschale eines wärmegedämmten Profiles, wobei der Isolier- und Verbindungssteg aus einem Kunststoffprofil und einer damit verbundenen Dämmleiste aus einem wärmedämmenden Isolierschaum besteht.The present invention relates to a method for producing a heat-insulating Insulating and connecting web for connecting an outer shell and an inner shell of a thermally insulated profile, the insulating and connecting web made of a plastic profile and an associated insulation strip a thermal insulation foam.

Wärmegedämmte Profile weisen grundsätzlich den Aufbau aus einer Außenschale, einer Innenschale und einem dazwischen liegenden, der Wärmedämmung dienenden Bereich auf.Thermally insulated profiles basically have the structure of an outer shell, an inner shell and an intermediate one, which serves for thermal insulation Area on.

Die Außen- und Innenschale ist bei einem wärmegedämmten Profil in der Regel aus Aluminium hergestellt, zum Zwecke der Wärmedämmung werden dann diese beiden Schalen durch aus Kunststoff gefertigte Isolier- und Verbindungsstege miteinander verbunden. Schon alleine durch die Verwendung von aus Kunststoff gefertigten Isolier- und Verbindungsstegen wird eine gewisse Wärmedämmung erreicht. The outer and inner shell is usually made of a thermally insulated profile Aluminum is made, for the purpose of thermal insulation then these two Shells through insulating and connecting bars made of plastic with each other connected. Simply by using insulating materials made of plastic and connecting bars a certain thermal insulation is achieved.

In der Praxis ist diese in der Regel aber nicht ausreichend, da die Luft innerhalb der Hohlkammer, die zwischen der Außenschale, der Innenschale und den Isolier- und Verbindungsstegen entsteht, frei zirkulieren kann, was für die gewünschte Wärmedämmung nachteilig ist.In practice, however, this is usually not sufficient because the air inside the Hollow chamber between the outer shell, the inner shell and the insulating and Connecting webs are created, can circulate freely, which is required for the desired thermal insulation is disadvantageous.

Es sind deshalb vielfältige Maßnahmen ergriffen worden, um diesen Nachteil zu beheben.Various measures have therefore been taken to remedy this disadvantage.

So ist es bekannt, den besagten Hohlraum vollständig auszuschäumen.So it is known to completely foam the said cavity.

Diese Maßnahme hat verschiedene Nachteile.This measure has several disadvantages.

Zum einen ist ein kontrolliertes und optimales Ausfüllen der Hohlkammer durch ein aufschäumendes Material nicht möglich und andererseits hat sich gezeigt, dass eine Verbesserung der Wärmedämmung erreicht werden kann, wenn die Hohlkammer nicht vollständig ausgefüllt ist, so dass zwischen der Außenschale und der Innenschale Luftspalte verbleiben, die aber ein Zirkulieren der Luft verhindern.On the one hand, a controlled and optimal filling of the hollow chamber by a foaming material not possible and on the other hand it has been shown that a Improvement in thermal insulation can be achieved if the hollow chamber is not is completely filled, so that between the outer shell and the inner shell Air gaps remain, which prevent air from circulating.

Man hat deshalb Isolier- und Verbindungsstege entwickelt, die mit in die Hohlkammer hineinragenden und zumindest eine Dämmleiste aus einem wärmedämmenden Isolierschaum aufweisenden Bereichen versehen sind.Insulation and connecting bars have therefore been developed that also fit into the hollow chamber protruding and at least one insulation strip made of a heat-insulating insulating foam areas are provided.

Dabei ist es bekannt, das Kunststoffprofil mit Stegen auszustatten, die als seitliche Begrenzungswandungen für die Dämmleiste dienen. Dies bedeutet, dass die Stege genauso weit über das Kunststoffprofil hinaus vorstehen wie die Dämmleiste selbst.It is known to equip the plastic profile with webs, which act as lateral boundary walls serve for the insulation strip. This means that the webs are the same protrude far beyond the plastic profile like the insulation strip itself.

Es ist auch schon vorgeschlagen worden, im wesentlichen nur die Dämmleiste deutlich über das Kunststoffprofil hinaus vorstehen zu lassen. Um dies zu erreichen, sind entweder Dämmleisten separat gefertigt und nach ihrer Aushärtung mit einem Kunststoffprofil verbunden worden oder man hat zunächst Kunststoffprofile mit einer Hohlkammer vorgefertigt, diese Hohlkammer mit wärmedämmendem Isolierschaum ausgefüllt und dann den wesentlichen Bereich der die Dämmleiste umschließenden Wandung weggefräst.It has also already been proposed, essentially only the insulation strip clearly to protrude beyond the plastic profile. To achieve this, either Insulation strips manufactured separately and after curing with a plastic profile have been connected or you first have plastic profiles with a hollow chamber prefabricated, this hollow chamber filled with insulating insulating foam and then the essential area of the wall surrounding the insulation strip milled away.

Die skizzierten Lösungen können in der Praxis nicht umfassend befriedigen, sei es wegen des hohen Materialeinsatzes für die Kunststoffprofile und/oder wegen zeitaufwändiger Montagearbeiten und häufig notwendiger, aufwendiger Nachbearbeitung.The solutions outlined cannot be fully satisfactory in practice, either because of the high use of material for the plastic profiles and / or because of time-consuming Assembly work and often necessary, time-consuming post-processing.

Der vorliegenden Erfindung liegt deshalb die Aufgabe zugrunde, ein Verfahren der gattungsgemäßen Art aufzuzeigen, mittels dessen ein eine sehr gute Wärmedämmung erzielender Isolier- und Verbundsteg kostengünstig herstellbar ist.The present invention is therefore based on the object of a method of to show generic type, by means of which a very good thermal insulation achieving insulating and composite web is inexpensive to manufacture.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, dass zunächst das Kunststoffprofil als im Querschnitt wannenförmiges Kunststoffprofil extrudiert und danach in den wannenförmigen Bereich ein Isolierschaum im flüssigen Zustand eingebracht und anschließend unter gleichzeitiger Verbindung mit dem Kunststoffprofil zu einer über den wannenförmigen Bereich hinaus vorstehenden Dämmleiste aufgeschäumt wird.This object is achieved in that first the plastic profile extruded as a trough-shaped plastic profile and then in the tub-shaped area introduced an insulating foam in the liquid state and then with simultaneous connection with the plastic profile to an over the tub-shaped area protruding insulation strip is foamed.

Die Dämmleiste wird also direkt an das Kunststoffprofil angeschäumt und bedarf somit keiner zusätzlichen Festlegung durch zusätzliche Befestigungsmittel, ebenso bedarf es keiner weiteren Bearbeitungszeit, um die Dämmleiste mit dem Kunststoffprofil zu verbinden.The insulation strip is therefore foamed directly onto the plastic profile and is therefore required no additional determination by additional fasteners, also required there is no further processing time to the insulation strip with the plastic profile connect to.

Es hat sich gezeigt, dass die Dämmleiste beim Aufschäumen auch ohne zusätzliche seitliche Begrenzung frei über das Kunststoffprofil hinaus aufgeschäumt werden kann, wobei einzige Voraussetzung hierfür ist, dass der wannenförmige Bereich des Kunststoffprofiles in seinen Seitenrändern so beschaffen ist, dass diese Seitenränder lotrecht oder leicht zueinander geneigt (z.B. 0 - 10°) zur Grundfläche des Kunststoffprofiles verlaufen und eine Führung des über die Ebene des Kunststoffprofiles hinaus aufschäumenden Dämmmaterials bilden. It has been shown that the insulation strip when foaming without additional lateral limitation can be foamed freely beyond the plastic profile, the only requirement for this is that the trough-shaped area of the plastic profile in its side edges is such that these side edges are perpendicular or slightly inclined to each other (e.g. 0 - 10 °) to the base of the plastic profile run and a guide of the foaming beyond the level of the plastic profile Form insulation material.

Insbesondere diese Führung kann ohne nennenswerten Kostenaufwand dadurch erheblich verbessert werden, dass beim Extrudieren des Kunststoffprofiles über den übrigen Bereich des Kunststoffprofiles hinaus vorstehende Führungsstege angeformt werden, über die die aufgeschäumte Dämmleiste nach oben vorsteht.In particular, this tour can be significant without significant costs be improved that when extruding the plastic profile over the rest Projecting guide webs beyond the plastic profile are formed, over which the foamed insulation strip protrudes upwards.

Diese Führungsstege ermöglichen es, das Kunststoffprofil selbst relativ schlank zu gestalten und trotzdem eine gute Führung für das aufschäumende Dämmmaterial zu erhalten.These guide bars enable the plastic profile itself to be relatively slim design and still a good guide for the foaming insulation material receive.

An den einander zugewandten Flanken der Führungsstege können vorteilhafter Weise vorspringende Halte- oder Ankerstege angeformt werden, die formschlüssig in die Seitenflanken der Dämmleiste hineinragen.On the mutually facing flanks of the guide webs can advantageously projecting retaining or anchor bars are molded, which form-fitting in the Protrude into the side flanks of the insulation strip.

Durch diese vergleichsweise einfache Maßnahme wird ein zusätzlicher Formschluss zwischen der aufgeschäumten Dämmleiste und dem Kunststoffprofil erzielt.This comparatively simple measure creates an additional form fit achieved between the foamed insulation strip and the plastic profile.

Die Erfindung betrifft weiterhin einen nach dem erfindungsgemäßen Verfahren hergestellten Isolier- und Verbindungssteg.The invention further relates to a manufactured by the method according to the invention Insulating and connecting bridge.

Dieser Isolier- und Verbindungssteg ist dadurch gekennzeichnet, dass das Kunststoffprofil im Querschnitt wannenförmig ausgebildet und dass die Dämmleiste in den wannenförmigen Bereich selbsthaftend eingeschäumt ist und frei über den wannenförmigen Bereich hinaus vorsteht.This insulating and connecting web is characterized in that the plastic profile trough-shaped in cross-section and that the insulation strip in the trough-shaped The area is self-adhesive foamed and free over the trough-shaped Area protrudes.

Ein derartiger Isolier- und Verbindungssteg kann in beliebigen Längen vorgefertigt und dann entsprechend den jeweils gegebenen Erfordernissen abgelängt werden, um ein wärmegedämmtes Profil herzustellen. Durch die Verbindung von Kunststoffprofil und Dämmleiste wird eine vergleichsweise hohe Steifigkeit erreicht, so dass ein derartiger Isolier- und Verbindungssteg sehr gut handhabbar ist. Such an insulating and connecting web can be prefabricated in any length and then cut to length as required to produce a thermally insulated profile. By connecting plastic profile and insulation strip a comparatively high rigidity is achieved, so that such Isolating and connecting bridge is very easy to handle.

Ein Metallbauer kann sich eine Vielzahl von unterschiedlich dimensionierten Verbindungs- und Isolierstegen gemäß vorliegender Erfindung lagermäßig bereit halten und dann je nach Anwendungsfall völlig problemlos und ohne jedwede Nachbearbeitung für die Herstellung von wärmegedämmten Profilen einsetzen.A metal worker can choose from a variety of differently dimensioned and keep insulating strips according to the present invention in stock and then depending on the application, completely problem-free and without any post-processing use for the production of thermally insulated profiles.

Weitere Merkmale der Erfindung sind Gegenstand weiterer Unteransprüche.Further features of the invention are the subject of further dependent claims.

In Fig. 1 is als Beispiel für wärmegedämmte Profile ein Blendrahmen 1 und ein Flügelrahmen 2 eines Fensters gezeigt.In Fig. 1 is a frame 1 and a sash as an example of thermally insulated profiles 2 of a window shown.

Der Blendrahmen 1 ist wie der Flügelrahmen 2 als Verbundprofil hergestellt. Jedes Verbundprofil umfasst eine aus einem Metallprofil bestehende Innenschale 3 und eine ebenfalls aus einem Metallprofil bestehende Außenschale 4. Die Innenschale 3 ist mit der Außenschale 4 jeweils über einen Verbindungssteg 5 bekannter Bauart sowie über einen erfindungsgemäßen Isolier- und Verbindungssteg 6 verbunden. The frame 1 is made as the casement 2 as a composite profile. each Composite profile comprises an inner shell 3 and a metal profile also from a metal profile outer shell 4. The inner shell 3 is with the outer shell 4 each via a connecting web 5 of known type and an insulating and connecting web 6 connected.

Es ist aber auch denkbar, bei entsprechenden Profilabmaßen den Profilverbund über zwei Isolier- und Verbindungsstege 6 vorzunehmen.However, it is also conceivable to use the profile assembly with appropriate profile dimensions to make two insulating and connecting webs 6.

Die detailliertere Darstellung gemäß Fig. 2 macht besonders deutlich, dass der erfindungsgemäße Isolier- und Verbindungssteg 5 aus einem Kunststoffprofil 7 und einer damit verbundenen Dämmleiste 8 aus einem wärmedämmenden Isolierschaum besteht.The more detailed representation according to FIG. 2 makes it particularly clear that the inventive one Insulating and connecting web 5 from a plastic profile 7 and one connected insulation strip 8 consists of a heat insulating foam.

Das Kunststoffprofil 7 dient dabei wie der handelsübliche Verbindungssteg 6 zur Verbindung von Innenschale 3 und Außenschale 4.The plastic profile 7 serves like the commercially available connecting web 6 for connection of inner shell 3 and outer shell 4.

Das Kunststoffprofil 7 ist ebenso wie der Verbindungssteg 5 in seinen Endbereichen 9 mit der Außenschale 4 bzw. der Innenschale 3 nach Art einer Nut/Feder-Verbindung form- und kraftschlüssig verbunden.The plastic profile 7, like the connecting web 5, is in its end regions 9 with the outer shell 4 or the inner shell 3 in the manner of a tongue and groove connection positively and non-positively connected.

Der zwischen den Endbereichen 9 liegende mittlere Bereich des Kunststoffprofiles 7 weist eine wannenförmige Gestaltung 10 auf, wobei die seitlichen Ränder durch über das Kunststoffprofil 7 nach oben geringfügig vorstehende Führungsstege 11 begrenzt sind. An den einander zugewandten Flanken der Stege 11 sind aufeinander zugerichtete Halte- oder Ankerstege 12 angeformt.The middle area of the plastic profile 7 lying between the end areas 9 has a trough-shaped design 10, the side edges by over the plastic profile 7 delimits slightly above projecting guide webs 11 are. At the mutually facing flanks of the webs 11 are facing each other Retaining or anchor webs 12 formed.

Ein Isolier- und Verbindungssteg 6 wird in der Weise hergestellt, dass zunächst das mit dem wannenförmigen Querschnitt versehene Kunststoffprofil 7 extrudiert wird, anschließend in den wannenförmigen Bereich 10 ein Isolierschaum im flüssigen Zustand eingebracht und anschließend unter gleichzeitiger Verbindung mit dem Kunststoffprofil 7 zu einer über den wannenförmigen Bereich 10 hinaus vorstehenden Dämmleiste 8 aufgeschäumt wird.An insulating and connecting web 6 is produced in such a way that first is extruded with the trough-shaped cross section provided plastic profile 7, then an insulating foam in the liquid state in the trough-shaped area 10 introduced and then with simultaneous connection with the plastic profile 7 to a protruding beyond the trough-shaped area 10 Insulation strip 8 is foamed.

Insbesondere durch die angeformten Führungsstege 11 wird es möglich, das Dämmmaterial gegenüber dem Kunststoffprofil 7 frei aufschäumen zu lassen bis deutlich über die obere Begrenzung des Kunststoffprofiles 7 hinaus, da durch die Führungsstege 11 praktisch vorgegeben ist, in welche Richtung sich das aufschäumende Material ausdehnen kann.In particular, through the integrally formed guide webs 11, it is possible that Allow the insulation material to foam up freely compared to the plastic profile 7 beyond the upper limit of the plastic profile 7, because of the guide bars 11 is practically predetermined in which direction the foaming Can expand material.

Der in den wannenförmigen Bereich 10 eingebrachte Isolierschaum verbindet sich selbsthaftend mit dem Kunststoffprofil 7, durch die in die seitlichen Flanken der aufgeschäumten Dämmleiste 8 hineinragenden Halte- oder Ankerstege 12 wird eine zusätzliche, formschlüssige Festlegung erreicht.The insulating foam introduced into the trough-shaped area 10 connects self-adhesive with the plastic profile 7, through which in the side flanks of the foamed Insulation strip 8 protruding holding or anchor bars 12 is an additional, positive determination reached.

Alternativ oder zusätzlich zu den Führungsstegen 11 kann das aufschäumende und die Dämmleiste 8 bildende Material während des Aufschäumvorganges auch durch seitliche Leitbleche kalibriert werden, wobei diese seitlichen Leitbleche aber nicht Bestandteil des Isolier- und Verbindungssteges 6 sind oder werden. Auch besteht die Möglichkeit, nach dem Aushärten der Dämmleiste 8 diese durch spanabhebende Bearbeitung in eine bestimmte Querschnittsform zu bringen.Alternatively or in addition to the guide webs 11, the foaming and the Insulation strip 8 forming material during the foaming process also by lateral Baffles are calibrated, but these side baffles are not part of it of the insulating and connecting web 6 are or will be. There is also Possibility, after the insulation strip 8 has hardened, by machining to bring it into a certain cross-sectional shape.

Es ist vorteilhaft, alle erforderlichen Verfahrensschritte in unmittelbarer zeitlicher Abfolge umzusetzen, das heißt, nach dem Extrudieren des Kunststoffprofiles 7 unmittelbar Isolierschaum im flüssigen Zustand in den wannenförmigen Bereich 10 einzubringen und den Aufschäumvorgang einzuleiten und gegebenenfalls sofort im Durchlauf eine spangebende Bearbeitung der Seitenränder der Dämmleiste 8 durchzuführen.It is advantageous to carry out all necessary process steps in immediate chronological order implement, that is, immediately after extruding the plastic profile 7 Introduce insulating foam in the trough-shaped area 10 in the liquid state and initiate the foaming process and, if necessary, immediately in the run to carry out machining of the side edges of the insulation strip 8.

Nach dem Aushärten der Dämmleiste 8 ist insgesamt ein Verbundprofil entstanden, welches problemlos gehandhabt und zwischengelagert werden kann.After the insulation strip 8 had hardened, a composite profile was created, which can be handled and stored without any problems.

Der erfindungsgemäße Isolier- und Verbindungssteg kann in relativ großen Längen hergestellt und zwischengelagert werden. Bei Bedarf kann dann ein Metallbauer entsprechende Längen von dem zwischengelagerten Profil abtrennen und entsprechend wärmegedämmte Profile herstellen.The insulating and connecting web according to the invention can be of relatively large lengths manufactured and temporarily stored. If necessary, a metal worker can do this Cut lengths from the intermediate profile and accordingly Manufacture thermally insulated profiles.

Die Fig. 3 bis 5 zeigen, dass die Möglichkeit besteht, die Dämmleiste 8 in verschiedenen Höhenabmessungen zu fertigen, um somit für unterschiedlichste Anwendungszwecke entsprechende Isolier- und Verbindungsstege 6 vorzufertigen.3 to 5 show that there is the possibility of the insulation strip 8 in different To produce height dimensions, so that for a wide variety of applications to prefabricate appropriate insulating and connecting webs 6.

Beim Ausführungsbeispiel nach Fig. 3 bis 5 ist der wannenförmige Bereich 10 des Kunststoffprofiles 7 im Bodenbereich eben ausgeführt.3 to 5, the trough-shaped region 10 of the Plastic profile 7 just executed in the floor area.

Fig. 6 zeigt ein Ausführungsbeispiel, bei dem im wannenförmigen Bereich 10 zwischen den beiden Führungsstegen 11 eine kerbenartige Einziehung 13 aufweist. Durch diese wird ein Teilbereich des Kunststoffprofiles 7 im Querschnitt extrem verringert, wodurch ein besonders hoher Isoliereffekt erzielt wird. Da die Dämmleiste 8 fest mit dem Kunststoffprofil 7 verbunden ist, führt diese Querschnittsverringerung des Kunststoffprofiles 7 nicht zu einer nennenswerten statischen Schwächung des gesamten Isolier- und Verbindungssteges 6.Fig. 6 shows an embodiment in which in the trough-shaped area 10 between the two guide webs 11 has a notch-like indentation 13. By a partial area of the plastic profile 7 is extremely reduced in cross section, whereby a particularly high insulation effect is achieved. Since the insulation strip 8 firmly with is connected to the plastic profile 7, this leads to a reduction in the cross section of the plastic profile 7 does not result in any significant static weakening of the entire insulation and connecting web 6.

Die Dämmleiste 8 kann wahlweise und je nach Bedarf aus einem Hart- oder aus einem Weichschaum gebildet werden.The insulation strip 8 can optionally and depending on requirements from a hard or from a Soft foam are formed.

Bevorzugt ist die Verwendung von Polyurethan-Schaum für die Bildung der Dämmleiste 8.The use of polyurethane foam for the formation of the insulation strip is preferred 8th.
