Abstract
Description
Die Erfindung betrifft einen Fensterrahmen, der aus Kunst stoff-Hohlkammerprofilen gefertigt ist.The invention relates to a window frame made of art fabric hollow chamber profiles is made.
Solche Kunststoffrahmen werden heutzutage im Fensterbau in großem Umfang eingesetzt. Die einzelnen Rahmenteile werden dabei aus entsprechend abgelängten, stranggepressten Hohlkam merprofilen hergestellt und anschließend zum kompletten Rahmen montiert. Diese seither bekannten Rahmenteile sind in ihrer Stabilität und Wärmedämmeigenschaft jedoch höheren Anforderun gen nicht gewachsen. Außerdem lassen sie sich nur sehr schwie rig in gebogener Form herstellen. Hierzu müssen in alle Kam mern der Hohlprofile so genannte Kunststoff-Ketten, die beid seitig eingekerbt sind, eingeführt werden, bevor das Profil unter Hitzeeinwirkung auf den gewünschten Radius gebogen wer den kann. Anschließend müssen die Ketten unter Einsatz hoher Zugkräfte wieder aus den Kammern entfernt werden. Bei der thermischen Verformung besteht dabei die Gefahr, dass sich die eingekerbte Kettenoberfläche in die Rahmenteile eindrückt, was auch auf der Außenseite der Rahmenteile sichtbar wird. Such plastic frames are used today in window construction used on a large scale. The individual frame parts are thereby from appropriately cut, extruded hollow manufactured and then to the complete frame assembled. These frame parts known since then are in their Stability and thermal insulation properties, however, have higher requirements not grown. In addition, they are very difficult Manufacture rig in a curved form. To do this, everyone has to of the hollow profiles so-called plastic chains, the two notched on each side, are inserted before the profile under the influence of heat to the desired radius that can. Then the chains must be high Tractive forces can be removed from the chambers. In the thermal deformation there is a risk that the notched chain surface presses into the frame parts what is also visible on the outside of the frame parts.
Der vorliegenden Erfindung liegt die Aufgabe zugrunde, einen Kunststoff-Fensterrahmen zu schaffen, der auch hohen Wärme dämm- und Stabilitätsanforderungen genügt und auf einfache Weise auch in Bogenform herstellbar ist.The present invention has for its object a To create plastic window frames that are also very warm Insulation and stability requirements are sufficient and simple Way can also be produced in sheet form.
Die Aufgabe wird mit einem Fensterrahmen, der aus Kunststoff- Hohlkammerprofilen gefertigt ist, gelöst, der erfindungsgemäß dadurch gekennzeichnet ist, dass die Hohlkammerprofile minde stens teilweise ausgeschäumt sind. Der in die Hohlkammern eingefüllte Schaum erhöht sowohl die Wärmedämmeigenschaften als auch die Stabilität des gesamten Rahmens. Die Hohlkammer profile können bereichsweise auch eine Bogenform aufweisen. Dabei können die Hohlkammerprofile mit einem Weichschaum aus geschäumt sein, wodurch sich eine leichte Biegbarkeit der Hohlkammerprofile ergibt. Es entfällt jetzt das umständliche Einziehen von Ketten in die Kammern der Profile vor dem Biege vorgang und ebenso das anschließende Herausziehen der Ketten aus dem gebogenen Profil. Der Schaum muss nach dem Biegevor gang nicht entfernt werden. Er verbleibt vielmehr in den Hohl kammern und erhöht dadurch die Wärmedämmeigenschaften sowie die Stabilität des gesamten Rahmens.The task is carried out with a window frame made of plastic Hollow chamber profiles is made, solved according to the invention is characterized in that the hollow chamber profiles are at least partially foamed. The one in the hollow chambers filled foam increases both the thermal insulation properties as well as the stability of the entire frame. The hollow chamber Profiles can also have an arc shape in some areas. The hollow chamber profiles can be made with a soft foam be foamed, which makes it easy to bend Hollow chamber profiles results. The cumbersome is no longer necessary Pulling chains into the chambers of the profiles before bending process and then pulling out the chains from the curved profile. The foam has to be after the bending not be removed. Rather, it remains in the hollow chambers and thereby increases the thermal insulation properties as well the stability of the entire frame.
Die Hohlkammerprofile können jedoch auch mit einem Hartschaum ausgeschäumt werden, sofern besonders hohe Stabilitätsanforde rungen an den Fensterrahmen im Vordergrund stehen.However, the hollow chamber profiles can also be made with a rigid foam can be foamed, if particularly high stability requirements the window frames are in the foreground.
Sowohl als Hart- als auch als Weichschäume eignen sich ins besondere PUR-Schäume.Both as rigid and flexible foams are suitable special PUR foams.
Die Erfindung betrifft außerdem ein Verfahren zur Herstellung von Fensterrahmen für Rundbogenfenster aus Kunststoff-Hohlkam merprofilen, das dadurch gekennzeichnet ist, dass die Kunst stoff-Hohlkammerprofile mindestens bereichsweise ausgeschäumt und anschließend in die gewünschte Form gebogen werden. Gegen über dem oben beschriebenen, bisher eingesetzten Verfahren zur Herstellung von Rundbogenfenstern weist dieses Verfahren er hebliche Vorteile bezüglich der Produktionszeiten und damit der Kosten auf. Vorzugsweise können die Hohlkammerprofile dabei mit einem PUR-Weichschaum ausgeschäumt werden.The invention also relates to a method of manufacture of window frames for arched windows made of plastic hollow merprofilen, which is characterized by the fact that art Foam hollow chamber profiles at least in some areas and then bent into the desired shape. Against above the previously used method for This process is demonstrated in the production of arched windows significant advantages in terms of production times and thus the cost on. Preferably, the hollow chamber profiles be foamed with a soft PUR foam.
Für die industrielle Fertigung ist es außerdem vorteilhaft, wenn die Hohlkammerprofile mittels einer Schaummaschine ausge schäumt werden.It is also advantageous for industrial production if the hollow chamber profiles out using a foam machine be foamed.
