Description

Verfahren zum Verstärken eines Kunststoff-HohlkammerprofilsMethod for reinforcing a plastic hollow chamber profile

Die Erfindung betrifft ein Verfahren zum Verstärken eines Hohlkammerprofils mit einem Verstärkungsprofil.The invention relates to a method for reinforcing a hollow chamber profile with a reinforcing profile.

Technisches GebietTechnical area

Hohlkammerprofile für die Herstellung von Fenstern und Türen werden in großem Umfang aus PVC-Formmassen extrudiert. Beim Kalibrieren und Abkühlen werden die Profile durch einen sogenannten Abzug durch die Kalibriereinrichtung gezogen, wobei zwangsläufig mehr oder weniger große Spannungen im PVC-Material eingefroren werden. Bei starker Erwärmung der zu Fenstern oder Türen bearbeiteten Profile durch Sonneneinstrahlung können diese Spannungen teilweise freigesetzt werden, so dass es zu einem Verzug der Profile kommt.Hollow profiles for the production of windows and doors are extruded to a large extent from PVC molding compounds. During calibration and cooling, the profiles are pulled through a so-called trigger through the calibration device, which inevitably more or less high voltages are frozen in the PVC material. In the event of severe heating of the profiles processed to windows or doors due to solar radiation, these stresses can be partially released so that the profiles become distorted.

Stand der TechnikState of the art

Es ist üblich, Hohlkammerprofile aus PVC-Formmassen mit Verstärkungsprofilen zu versehen. Die Verstärkungsprofile bestehen gewöhnlich aus Stahl. Es sind aber auch Verstärkungsprofile aus glasfaserverstärkten Kunststoffen oder sogenannte thermisch getrennte Stahlprofile für diesen Zweck bekannt.It is customary to provide hollow chamber profiles made of PVC molding compounds with reinforcing profiles. The reinforcing profiles are usually made of steel. But there are also known reinforcing profiles of glass fiber reinforced plastics or so-called thermally separated steel profiles for this purpose.

Die Verstärkungsprofile werden vor dem Verschweißen der abgelängten und auf Gehrung geschnittenen PVC-Profile in eine sogenannte Verstärkungskammer der Hohlprofile - insbesondere der Blendrahmenprofile für den Blendrahmen und der Flügelrahmenprofile für den Flügelrahmen - eingeschoben und mit einer die Außenkontur des Hohlkammerprofils durchdringenden Verschraubung mit dem Hohlkammerprofil verschraubt. Aufgrund von Fertigungstoleranzen ist jedoch nicht immer gewährleistet, dass die Verstärkungsprofile an der Innenkontur der Verstärkungskammer anliegen. Bei einer etwaigen Verformung des Hohlkammerprofils durch Wärmeeinwirkung und dadurch freigesetzte Spannungen verzieht sich das PVC-Profil, bevor die Verstärkungsprofile auf Biegung beansprucht werden und damit ihre Verstärkungswirkung entfalten.The reinforcing profiles are inserted before welding the cut and mitered PVC profiles in a so-called reinforcing chamber of the hollow sections - especially the frame profiles for the frame and the sash profiles for the sash - and screwed with a the outer contour of the hollow chamber profile penetrating fitting with the hollow chamber profile. Due to manufacturing tolerances, however, it is not always guaranteed that the reinforcing profiles abut the inner contour of the reinforcing chamber. In a possible deformation of the hollow chamber profile by the action of heat and thus released stresses warping the PVC profile before the reinforcing profiles be subjected to bending and thus develop their reinforcing effect.

Aufgabetask

Aufgabe der vorliegenden Erfindung ist es daher, ein Verfahren zum Verstärken eines Kunststoff-Hohlkammerprofils zur Verfügung zu stellen, das diese Nachteile nicht aufweist.The object of the present invention is therefore to provide a method for reinforcing a plastic hollow chamber profile which does not have these disadvantages.

Darstellung der ErfindungPresentation of the invention

Diese Aufgabe wird gelöst durch ein Verfahren nach Anspruch 1, bevorzugt in Verbindung mit einem oder mehreren der Merkmale der Unteransprüche.This object is achieved by a method according to claim 1, preferably in conjunction with one or more of the features of the subclaims.

Das für das erfindungsgemäße Verfahren verwendete Hohlkammerprofil besteht wenigstens weitgehend aus Kunststoff, bevorzugt aus Hart-PVC (PVC-U). Die Profil-Außenwand weist bevorzugt eine wesentlich größere Wandstärke auf als die Innenstege des Hohlkammerprofils. Bevorzugt weisen die Profil-Außenwand eine Wandstärke von 2,5 bis 3 mm und die Innenstege eine Wandstärke von weniger als 2 mm auf.The hollow chamber profile used for the method according to the invention consists at least largely of plastic, preferably of rigid PVC (PVC-U). The profile outer wall preferably has a substantially greater wall thickness than the inner webs of the hollow chamber profile. Preferably, the profile outer wall has a wall thickness of 2.5 to 3 mm and the inner webs have a wall thickness of less than 2 mm.

Die Verstärkungskammer wird wenigstens in Teilbereichen von der Profil-Außenwand und in anderen Teilbereichen von den Innenstegen des Hohlkammerprofils gebildet, so dass die Verstärkungskammer in Teilbereichen, bedingt durch die größere Wandstärke der Profil-Außenwände im Vergleich zu den Innenstegen, eine unterschiedliche Wandstärke und damit unterschiedliche Steifigkeit aufweist.The reinforcing chamber is formed at least in some areas of the profile outer wall and in other parts of the inner webs of the hollow chamber profile, so that the reinforcing chamber in partial areas, due to the greater wall thickness of the profile outer walls compared to the inner webs, a different wall thickness and thus different Having stiffness.

Das Verstärkungsprofil weist mehrere Schenkel auf, wobei sowohl eine offene Kontur als auch eine geschlossene Kontur des Stahlprofiles innerhalb der Erfindung eingesetzt werden können. Das Verstärkungsprofil ist so geformt und wird so in die Verstärkungskammer eingeschoben, dass einer der Schenkel des Verstärkungsprofils im Bereich der späteren Verschraubung zunächst gegenüber der Profil-Außenwand beabstandet ist. Beim Anziehen der Verschraubung wird nicht nur dieser beabstandete Bereich des Verstärkungsprofils an die Profil-Außenwand angezogen, das Verstärkungsprofil wird erfindungsgemäß zusätzlich geschwenkt, erfährt also eine Drehbewegung oder eine Kombination aus einer Drehbewegung und einer translatorischen Bewegung. Durch diese Schwenkbewegung wird das Verstärkungsprofil in einem von der Verschraubung beabstandeten Bereich fest an die Innenwandung der Verstärkungskammer angepresst. Nach einer besonders bevorzugten Ausführungsform der Erfindung erfolgt dieses Anpressen an die Innenwandung der Verstärkungskammer in einem Bereich der Verstärkungskammer, an dem diese durch die Profil-Außenwandung gebildet wird, mit anderen Worten, das Verstärkungsprofil wird von innen an die Profil-Außenwand gepresst. Hierdurch ist ein optimaler Kraftfluss zwischen dem Verstärkungsprofil und der Außenkontur des Hohlkammerprofils gewährleistet.The reinforcing profile has a plurality of legs, wherein both an open contour and a closed contour of the steel profile can be used within the invention. The reinforcing profile is shaped and is inserted into the reinforcing chamber such that one of the legs of the reinforcing profile in the region of the subsequent screwing first is spaced from the profile outer wall. When tightening the screw not only this spaced portion of the reinforcing profile is attracted to the profile outer wall, the reinforcing profile is additionally pivoted according to the invention, so undergoes a rotational movement or a combination of a rotational movement and a translational movement. By this pivoting movement, the reinforcing profile is pressed firmly against the inner wall of the reinforcing chamber in a region spaced from the screw connection. According to a particularly preferred embodiment of the invention, this pressing is carried out on the inner wall of the reinforcing chamber in a region of the reinforcing chamber, where it is formed by the profile outer wall, in other words, the reinforcing profile is pressed from the inside to the outer profile wall. As a result, an optimal force flow between the reinforcing profile and the outer contour of the hollow chamber profile is ensured.

Nach einer besonders bevorzugten Ausführungsform der Erfindung verläuft wenigstens einer der Bereiche der Innenwandung der Verstärkungskammer, an die das Verstärkungsprofil angepresst wird, etwa parallel zur Außensichtfläche bzw. zur Verglasungsebene. Mit "etwa parallel" wird hierbei ein Winkel zwischen 0° und 10° zur Außensichtfläche bzw. Verglasungsebene verstanden.According to a particularly preferred embodiment of the invention, at least one of the regions of the inner wall of the reinforcing chamber to which the reinforcing profile is pressed extends approximately parallel to the outer visible surface or to the glazing plane. By "approximately parallel" is meant an angle between 0 ° and 10 ° to the outer viewing surface or glazing plane.

Bei einem insbesondere durch thermische Beanspruchung ausgelösten Verzug des Hohlkammerprofils in Teilbereichen wird daher das Verstärkungsprofil unmittelbar auf Biegung beansprucht und wirkt somit einem Verziehen des Hohlkammerprofils entgegen.In a particular caused by thermal stress distortion of the hollow chamber profile in partial areas, therefore, the reinforcing profile is directly subjected to bending and thus counteracts a distortion of the hollow chamber profile.

Nach einer besonders bevorzugten Ausführungsform der Erfindung wird das Verstärkungsprofil beim Anziehen der Verschraubung derart geschwenkt, dass die hieraus resultierende Rotationskomponente der Schwenkbewegung einer Rotation von mindestens 3° entspricht.According to a particularly preferred embodiment of the invention, the reinforcing profile when tightening the screw is pivoted so that the resulting rotational component of the pivotal movement corresponds to a rotation of at least 3 °.

Das Verstärkungsprofil wird mit dem Hohlkammerprofil insbesondere verschraubt. Es liegt aber innerhalb der Erfindung, wenn die Verbindung beispielsweise durch Nieten o. dgl. erfolgt.The reinforcing profile is screwed to the hollow chamber profile in particular. It is within the invention, however, if the connection takes place, for example, by riveting o.

Wege zur Ausführung der ErfindungWays to carry out the invention

In Fig. 1 ist ein dem Fachmann an sich bekanntes Flügelrahmenprofil, Marke Trocal der Anmelderin, dargestellt. Das als Hohlkammerprofil 1 ausgeführte Flügelrahmenprofil weist eine Profil-Außenwand 2 mit einer durchgehenden Wandstärke von ca. 3 mm auf. Die Innenstege 4, 5, 6, 7 teilen das Hohlkammerprofil 1 in mehrere Hohlkammern 15, 16, 17. Die Hohlkammer 16 bildet dabei die Verstärkungskammer 3. Die Innenstege 4 - 7 haben eine wesentlich geringere Wandstärke als die Profil-Außenwand 2, nämlich ca. 1 bis 1,5 mm.In Fig. 1 is a specialist in the art per se known wing frame profile, Trocal brand of the Applicant, shown. The wing frame profile designed as a hollow chamber profile 1 has a profile outer wall 2 with a continuous wall thickness of approximately 3 mm. The inner webs 4, 5, 6, 7 divide the hollow chamber profile 1 into a plurality of hollow chambers 15, 16, 17. The hollow chamber 16 forms the reinforcing chamber 3. The inner webs 4-7 have a substantially smaller wall thickness than the profile outer wall 2, namely approx 1 to 1.5 mm.

Das Verstärkungsprofil 10 besteht aus Stahl einer Wandstärke von 2 mm und ist so geformt, dass es nach dem Einschieben in die Verstärkungskammer 3 zumindest in einigen Bereichen, insbesondere dem Bereich der Verschraubung 18 und den späteren Anpressbereichen 11, 23 und 24 nicht an der Innenwandung der Verstärkungskammer 3 anliegt.The reinforcing profile 10 is made of steel with a wall thickness of 2 mm and is shaped so that, after insertion into the reinforcing chamber 3 at least in some areas, in particular the region of the screw 18 and the subsequent Anpressbereichen 11, 23 and 24 is not applied to the inner wall of the reinforcing chamber 3.

In Fig. 1 ist der sogenannte Euronutbereich mit dem Bezugszeichen 8 gekennzeichnet. Dieser stellt im Sinne der vorliegenden Erfindung einen Teilbereich der Profil-Außenwand 2 dar.In Fig. 1 the so-called Euronutbereich is denoted by the reference numeral 8. This represents a part of the profile outer wall 2 in the sense of the present invention.

Nach dem Anziehen der in den Fig. lediglich symbolisch dargestellten Verschraubung 18 wird das Verstärkungsprofil 10 um den in Fig. 2 mit dem Bezugszeichen 19 dargestellten Bereich geschwenkt bzw. rotiert, so dass der von der Verschraubung 18 beabstandete abgewinkelte Schenkelbereich in den Anpressbereichen 11 und 23 fest an die Innenkontur der Verstärkungskammer 3 gepresst wird. Zugleich wird der Schenkel 22 (Fig. 2) des Verstärkungsprofils 10 im Bereich der Euronut 8, genauer im Anpressbereich 24, an die Innenkontur der Verstärkungskammer 3 gepresst. Durch diese kraftschlüssige Verbindung zwischen dem Verstärkungsprofil 10 und dem Hohlkammerprofil 1 wird eine unmittelbare Übertragung etwaiger Biegungen des Hohlkammerprofils 1 auf das Verstärkungsprofil 10 sichergestellt und von diesem weitgehend abgefangen, so dass beispielsweise durch Schrumpfspannungen ausgelöste Verbiegungen des Hohlkammerprofils 1 minimiert werden.After tightening the screw 18 shown only symbolically in the figures, the reinforcing profile 10 to the in Fig. 2 pivoted or rotated with the reference numeral 19, so that the angled leg portion spaced from the screw 18 in the pressing areas 11 and 23 is pressed firmly against the inner contour of the reinforcing chamber 3. At the same time, the leg 22 ( Fig. 2 ) of the reinforcing profile 10 in the region of the Euronut 8, more precisely in the pressing region 24, pressed against the inner contour of the reinforcing chamber 3. Through this frictional connection between the reinforcing profile 10 and the hollow chamber profile 1 an immediate transfer of any bends of the hollow chamber profile 1 is ensured on the reinforcing profile 10 and largely intercepted by it, so that, for example, caused by shrinkage stresses bending the hollow chamber profile 1 are minimized.

Im Bereich der Anpressbereiche 11 und 23 (Fig. 1, Fig. 2) verläuft die Profil-Außenwand 2 in einem engen Bogen von ca. 90° und geht - in Richtung der Außensichtfläche betrachtet - in einen horizontalen, also senkrecht zur Außensichtfläche bzw. zur Verglasungsebene verlaufenden Bereich über. Der Bereich 23 verläuft dabei etwa parallel zur Verglasungsebene bzw. zur Außensichtfläche des Profils 1, so dass eine optimale Abtragung der durch eine Biegung auftretenden Kräfte auf das Verstärkungsprofil 10 ermöglicht wird. Auch der Anpressbereich 24, auf den der Schenkel 22 des Verstärkungsprofils 10 beim Anziehen der Verschraubung 18 gepresst wird, verläuft annähernd senkrecht zur Verglasungsebene bzw. zur Außensichtfläche des Hohlkammerprofils 1.In the area of the contact areas 11 and 23 ( Fig. 1, Fig. 2 ) runs the profile outer wall 2 in a narrow arc of about 90 ° and is - viewed in the direction of the outer viewing surface - in a horizontal, ie perpendicular to the outer viewing surface or the glazing plane extending area. In this case, the region 23 runs approximately parallel to the glazing plane or to the outer visible surface of the profile 1, so that optimum removal of the forces occurring due to bending on the reinforcing profile 10 is made possible. Also the contact area 24, on which the legs 22 of the reinforcing profile 10 when tightening the screw 18 is pressed, extends approximately perpendicular to the glazing plane or to the outer visible surface of the hollow chamber profile first

In den Fig. 3 und 4 ist das gleiche Hohlkammerprofil 2 wie in den Fig. 1 und 2 dargestellt, lediglich das Verstärkungsprofil 10' weist auf der Innenseite einen verkürzten Schenkel auf. Die Funktionsweise ist prinzipiell jedoch die Gleiche: Das Verstärkungsprofil 10' wird beim Anziehen der Verschraubung 18 etwa um den Bereich 20 geschwenkt bzw. rotiert und in den Bereichen 11' und 23' an die Innenkontur der Verstärkungskammer 3 angepresst.In the 3 and 4 is the same hollow chamber profile 2 as in the Fig. 1 and 2 shown, only the reinforcing profile 10 'has on the inside a shortened leg. However, the principle of principle is the same: the reinforcement profile 10 'is pivoted or rotated about the region 20 when tightening the screw connection 18 and pressed against the inner contour of the reinforcement chamber 3 in the regions 11' and 23 '.

Das abgewandte Ende des Verstärkungsprofils 10' stützt sich in diesem Ausführungsbeispiel an dem Nocken 9 der Verstärkungskammer 3 ab.The opposite end of the reinforcing profile 10 'is supported in this embodiment on the cam 9 of the reinforcing chamber 3.

In den Fig. 5 und 6 ist ein alternatives Ausführungsbeispiel der vorliegenden Erfindung dargestellt: Das hier verwendete Hohlkammerprofil 1' weist ähnlich wie das in den Fig. 1 bis 4 dargestellte Flügelrahmenprofil eine Profil-Außenwand 2' mit einer durchgehenden Nenn-Wandstärke von 3 mm und Innenstege 4', 5', 6' und 7' mit etwa 1 mm Wandstärke auf. Das Verstärkungsprofil 10" weist eine solche Kontur auf, dass nach dem Einschieben in die Verstärkungskammer 3' der spätere Verschraubungsbereich zunächst beabstandet zu der Innenkontur der Verstärkungskammer 3' zu liegen kommt. Beim Anziehen der in den Fig. 5 und 6 nur symbolisch dargestellten Verschraubung 18' wird das Verstärkungsprofil 10" etwa um den Bereich 21 gedreht bzw. geschwenkt und dabei mit dem Ende des freien Schenkels des Verstärkungsprofils 10" im Bereich der Euronut 8 - Anpressbereich 11" - an die Innenkontur der Verstärkungskammer 3' angepresst. Zugleich erfolgt eine Anpressung des anderen Schenkels des Verstärkungsprofils 10" in zwei unterschiedlichen, nahe an der Profil-Außenwand 2' liegenden Bereichen 25 und 26 des Innensteges 5'. Auch hierdurch wird eine hervorragende kraftschlüssige Verbindung zwischen Verstärkungsprofil 10" und dem Hohlkammerprofil 1' bewirkt, so dass etwaige Schrumpfungen und dadurch ausgelöste Verbiegungen des Hohlkammerprofils 1' zuverlässig minimiert werden.In the FIGS. 5 and 6 an alternative embodiment of the present invention is shown: The hollow chamber profile 1 'used here has similar to that in the Fig. 1 to 4 illustrated sash profile a profile outer wall 2 'with a continuous nominal wall thickness of 3 mm and inner webs 4', 5 ', 6' and 7 'with about 1 mm wall thickness. The reinforcing profile 10 "has such a contour that, after being pushed into the reinforcing chamber 3 ', the later screwed area initially comes to rest at a distance from the inner contour of the reinforcing chamber 3' FIGS. 5 and 6 only symbolically shown screw 18 ', the reinforcing profile 10 "is rotated or pivoted about the region 21 and thereby pressed with the end of the free leg of the reinforcing profile 10" in the Euronut 8 - Anpressbereich 11 "- to the inner contour of the reinforcing chamber 3' At the same time, the other is pressed Leg of the reinforcing profile 10 "in two different, close to the profile outer wall 2 'lying areas 25 and 26 of the inner web 5' This caused bending of the hollow chamber profile 1 'are reliably minimized.
