Abstract

A method of making a thermally insulating metal profile, comprising two profiled sections (1,2 ; 7,8 ; 14,16) with respectively at least one in the cross-section C-shaped formation and clamping profiled barriers (3,4 ; 9,10 ; 15 ; 21-28) of thermally insulating material which get into the open C of both said profiled sections, whereby between the said clamping profiled barriers at least one oversized hollow body (5, 11, 5a-5d) is arranged which consists of an inelastic material of low restoring torque and which braces the said clamping profiled barriers with the profiled sections, characterized in, that a hollow body (5, 11, 5a-5d) is used which does not show an oversize in its original form, that the hollow body without oversize is set between the clamping profiled barriers (3,9 ; 9,10 ; 15 ; 21-28) and is then widened in comparison to its original form and is deformed permanently.

Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines wärmegedämmten Metallprofils, bestehend aus zwei Teilprofilstäben mit jeweils mindestens einer im Querschnitt C-förmigen Ausbildung und in das offene C beider Teilprofilstäbe eingreifenden Klemmprofilleisten aus wärmeisolierendem Material, wobei zwischen den Klammprofilleisten mindestens ein ein Übermaß aufweisender Hohlkörper aus einem unelastischen und rückstellarmen Werkstoff angeordnet ist, der die Klammprofilleisten mit den Teilprofilstäben verspannt, sowie ein nach diesem Verfahren hergestelltes wärmegedämmtes metallprofil.The invention relates to a method for producing a thermally insulated metal profile, consisting of two partial profile bars, each with at least one cross-sectionally C-shaped design and clamping profile strips engaging in the open C of both partial profile bars, made of heat-insulating material, at least one hollow body having an oversize between the clamp profile strips Inelastic and low-resilience material is arranged, which braces the clamp profile strips with the partial profile bars, as well as a thermally insulated metal profile produced by this method.

Ein derartiges Verfahren ist durch die DE-A1-26 34 668 bekannt geworden. Bei diesem Verfahren wird ein in seiner ursprünglichen Form ein Übermaß aufweisender Hohlkörper zwischen die Klammprofilleisten eingepreßt, so daß entweder der Hohlkörper selbst oder die Klemmprofilleisten elastisch ausgebildet sein müssen, da andernfalls der Hohlkörper nicht in seine Klemmlage gebracht werden kanrr. Dadurch wird die Verbindung der Teilprofilstäbe immer etwas elastisch bleiben und die Steifigkeit des Verbundprofils herabgesetzt, da die Verbindung derTeiiprofiistäbe nich starr ist.Such a method is known from DE-A1-26 34 668. In this method, an oversize hollow body is pressed between the clamp profile strips in its original form, so that either the hollow body itself or the clamp profile strips must be elastic, otherwise the hollow body cannot be brought into its clamped position. As a result, the connection of the partial profile bars will always remain somewhat elastic and the rigidity of the composite profile will be reduced, since the connection of the partial professional bars is not rigid.

Nach der DE-A1-25 31 267 soll ein Vakuumschlauch zwischen die Teilprofilstäbe gelegt werden und diese (eiastisch) mit den Klemmprofilleisten verspannen. Für viele Fenster- und Türkonstruktionen ist eine Elastizität des Verbundprofils nur in sehr begrenztem Umfang zulässig. Der Vakuumschlauch wird nach dieser Entgegenhaltung beim Zusammenbau der Teilprofilstäbe nicht gegenüber seiner ursprünglichen Gestalt aufgeweitet, sondern er wird nach einer Schrumpfung durch Evakuierung in seine ursprüngliche Form annähernd wieder zurückgeführt.According to DE-A1-25 31 267, a vacuum hose is to be placed between the partial profile bars and (elastic) bracing them with the clamping profile strips. For many window and door constructions, the elasticity of the composite profile is only permitted to a very limited extent. According to this document, the vacuum hose is not expanded compared to its original shape when assembling the partial profile rods, but is approximately returned to its original shape after shrinking by evacuation.

Außerdem drückt der Vakuumschlauch nicht nur gegen die Klemmprofilleisten sondern auch gegen die Teilprofilstäbe. Aus diesem Grunde müssen diese an den Druckstellen verdickt ausgebildet werden.In addition, the vacuum hose not only presses against the clamping profile strips but also against the partial profile bars. For this reason, these must be thickened at the pressure points.

Aus der CH-A-549 753 ist es ferner bekannt, die Klemmprofilleisten durch eine bei Wärmezufuhr expandierbare Zwischenschicht an die Teilprofilleisten anzupressen Die Zwischenschicht kann aus einer vulkanisierbaren, treibmittelhaltigen Kunstgummimischung bestehen. Diese bekannte Anordnung hat den Nachteil, daß bei ungleichmäßiger Wirkung des Treibmittels ein Verziehen des Metallprofils erfolgt, und damit eine Maßhaltigkeit der Teilprofilstäbe nicht garantiert werden kann.From CH-A-549 753 it is also known to press the clamping profile strips onto the partial profile strips by means of an intermediate layer which is expandable when heat is added. The intermediate layer can consist of a vulcanizable, propellant-containing synthetic rubber mixture. This known arrangement has the disadvantage that when the propellant acts unevenly, the metal profile is warped, and therefore dimensional accuracy of the partial profile bars cannot be guaranteed.

Für bestimmte Anwendungszwecke ist es erforderlich, auch nicht parallel angeordnete Teilprofilstäbe wärmeisolierend miteinander verbinden zu können.For certain applications, it is necessary to be able to connect partial profile bars that are not arranged in parallel with one another in a heat-insulating manner.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, bei dem die für das Einbringen des Hohlkörpers montagebedingte Elastizität entweder des Hohlkörpers oder der Klemmprofilleisten nicht erfoderlich ist und auch keine treibmittelhaltige Zwischenschicht benötigt wird.The invention has for its object to provide a method of the type mentioned, in which the assembly-related elasticity for the introduction of the hollow body either the hollow body or the clamping profile strips is not required and no propellant-containing intermediate layer is required.

Erfindungsgemäß wird dies dadurch erreicht, daß ein Hohlkörper verwendet wird, der in seiner ursprünglichen Form kein Übermaß aufweist, daß der Hohlkörper ohne Übermaß zwischen die Klemmprofilleisten gelegt und dann gegenüber seiner ursprünglichen Form aufgeweitet und bleibend verformt wird.According to the invention, this is achieved in that a hollow body is used which has no oversize in its original shape, that the hollow body is placed between the clamping profile strips without oversize and then expanded and permanently deformed relative to its original shape.

Es ist vorteilhaft, die Aufweitung durch einen Dorn vorzunehmen, der durch den Hohlraum des Hohlprofils gezogen wird.It is advantageous to carry out the expansion by means of a mandrel which is pulled through the cavity of the hollow profile.

Bei einer weiteren Ausführungsform der Erfindung ist vorgesehen, daß der in seiner ursprünglichen Form ein Übermaß aufweisende Hohlkörper in gekühltem Zustand ohne Übermaß zwischen die Klemmprofilleisten gelegt und durch Wärmedehnung in seine ursprüngliche Form zurückgeführt wird.In a further embodiment of the invention it is provided that the hollow body, which has an oversize in its original shape, is placed in the cooled state without oversize between the clamping profile strips and is returned to its original shape by thermal expansion.

Der Werkstoff des Hohlkörpers besteht vorzugsweise aus einer Legierung folgender Zusammensetzung:

Figure imgb0001
The material of the hollow body preferably consists of an alloy of the following composition:
Figure imgb0001

Der Vorteil des erfindungsgemäßen Metallprofils besteht darin, daß es besonders leicht mit einfachen Mitteln auch an unzugänglichen Stellen der Teilprofilstäbe zusammengebaut werden kann. Die Befestigung der Teilprofilstäbe ist ausreichend steif und absolut dicht gegenüber Gas und Feichtigkeit.The advantage of the metal profile according to the invention is that it can be assembled particularly easily with simple means even in inaccessible places on the partial profile bars. The fastening of the partial profile bars is sufficiently rigid and absolutely tight against gas and moisture.

Im Folgenden soll anhand mehrerer Ausführungsbeispiele das erfindungsgemäße Metallprofil näher erläutert werden. Es zeigen:

  • Fig. 1 einen Querschnitt durch das erfindungsgemäße Metallprofil mit zwei parallel zueinander angeordneten Teilprofilstäben.
  • Fig. 2 Querschnitt durch einen Hohlkörper zum Befestigen der Klemmprofilleisten.
  • Fig. 3 Längsschnitt durch ein Metallprofil entsprechend Fig. 1 während der Verspannung der Klemmprofilleisten.
  • Fig. 4 Querschnitt durch ein Metallprofil mit rechtwinklig zueinander angeordneten Teilprofilstäben,
  • Fig. 5 Querschnitt durch ein unzugängliches Eckprofil,
  • Fig. 6 Längsschnitt durch ein gekapseltes Metallprofil, mit dem parallel angeordnete und isolierte Wandplatten miteinander befestigt werden.
The metal profile according to the invention is to be explained in more detail below on the basis of several exemplary embodiments. Show it:
  • Fig. 1 shows a cross section through the metal profile according to the invention with two partial profile bars arranged parallel to each other.
  • Fig. 2 cross section through a hollow body for attaching the clamping profile strips.
  • Fig. 3 longitudinal section through a metal profile corresponding to FIG. 1 during the clamping of the clamping profile strips.
  • 4 cross section through a metal profile with partial profile bars arranged at right angles to one another,
  • 5 cross section through an inaccessible corner profile,
  • Fig. 6 longitudinal section through an encapsulated metal profile, with the parallel and insulated wall panels can be fastened together.

In Fig. 1 ist ein Metallprofil entsprechend dem Erfindungsvorschlag dargestellt, das aus zwei Teilprofilstäben 1, 2, zwei Klemmprofilleisten 3, 4 und einem Hohlkörper 5 besteht. Der Hohlkörper 5 ist in aufgeweitetem Zustand gezeigt und verspannt dadurch die Klemmprofilleisten, so daß eine feste Verbindung zwischen den Teilprofilleisten eintritt.In Fig. 1, a metal profile is shown according to the invention proposal, which consists of two partial profile bars 1, 2, two clamping profile strips 3, 4 and a hollow body 5. The hollow body 5 is shown in the expanded state and thereby braces the clamping profile strips, so that a firm connection between the partial profile strips occurs.

In Fig. 2 ist der Hohlkörper 5 in vergrößerter Darstellung gezeigt. Die zackenförmigen Ausbildungen am äußeren Umfang unterstützen die Festigkeit der Klemmverbindung.In Fig. 2 the hollow body 5 is shown in an enlarged view. The jagged formations on the outer circumference support the strength of the clamp connection.

In Fig. 3 sind die Teilprofilstäbe 1, 2 sowie Klemmprofilleisten 3, 4 während der Verspannung gezeigt. Dabei wird ein Dorn 6 durch den Hohlkörper 5 in Pfeilrichtung gezogen, wodurch der Hohlkörper aufgeweitet wird.In Fig. 3 the partial profile bars 1, 2 and clamping profile strips 3, 4 are shown during the bracing. A mandrel 6 is pulled through the hollow body 5 in the direction of the arrow, whereby the hollow body is expanded.

Fig. 4 zeigt eine einfache Eckverbindung zwischen den Teilprofilstäben 7, 8. Die Klemmprofilleisten 9, 10 werden durch den aufgeweiteten Hohlkörper 11 gegen die C-förmigen Ausbildungen der Teilprofilstäbe verspannt.Fig. 4 shows a simple corner connection between the partial profile bars 7, 8. The clamping profile strips 9, 10 are braced by the expanded hollow body 11 against the C-shaped configurations of the partial profile bars.

Fig. 5 zeigt einen besonders vorteilhaften Anwendungsfall der Erfindung, bei dem ein nach außen und innen vollständig geschlossenes, doppelwandiges Kastenprofil 19 entsteht. Die Klemmprofilleisten 21-28 sind innerhalb der Doppelwand des Kastenprofils 19 untergebracht, und die Hohlkörper 5a--d können ohne Eingriff von der Wandseite 20 her aufgeweitet werden. Falls ein vollständig geschlossener, doppelwandiger Behälter hergestellt werden soll, ist es vorteilhaft, die Verbindung durch Schrumpfung der Hohlkörper herzustellen. Dieses geschieht zweckmäßigerweise dadurch, daß die Hohlkörper 5a--d vor dem Einschieben in die Klemmprofilleisten 21-28 gekühlt werden.FIG. 5 shows a particularly advantageous application of the invention, in which a double-walled box section 19 is created which is completely closed towards the outside and inside. The clamping profile strips 21-28 are accommodated within the double wall of the box profile 19, and the hollow bodies 5a-d can be widened from the wall side 20 without intervention. If a completely closed, double-walled container is to be produced, it is advantageous to produce the connection by shrinking the hollow body. This expediently takes place in that the hollow bodies 5a-d are cooled before being inserted into the clamping profile strips 21-28.

Fig. 6 zeigt ein weiteres, bevorzugtes Anwendungsbeispiel des erfindungsgemäßen Verfahrens. Hier wird eine Außenwand 12 an der Innenwand 13 durch das erfindungsgemäße Klemmsystem befestigt. Das Klemmsystem besteht aus einer Grundplatte 14, die mit der Außenwand 12 verschraubt ist. In der C-förmigen Ausbildung der Grundplatte 14 liegt das wärmeisolierende Material 15. Durch den Hohlkörper 5 wird das wärmeisolierende Material in den C-förmigen Ausbildungen der Grundplatte 14 und der gegenüberliegenden Verankerungsplatte 16 verspannt. Zur Sicherung bei höchster Beanspruchung sind Hakenprofile 17, 18 vorgesehen.6 shows a further, preferred application example of the method according to the invention. Here, an outer wall 12 is fastened to the inner wall 13 by the clamping system according to the invention. The clamping system consists of a base plate 14 which is screwed to the outer wall 12. The heat-insulating material 15 lies in the C-shaped design of the base plate 14. The heat-insulating material is braced by the hollow body 5 in the C-shaped designs of the base plate 14 and the opposite anchoring plate 16. Hook profiles 17, 18 are provided for securing under the highest loads.

Bei der Herstellung eines erfindungsgemäßen Metallprofils kommt es im wesentlichen darauf an, daß eine Verspannung durch Übermaß des Hohlkörpers aufgebracht wird. Das Übermaß kann dadurch erzeugt werden, daß der Hohlkörper zwischen die Klammprofilleisten gelegt und aufgeweitet wird. Der Hohlkörper kann aber bereits im Ausgangszustand ein Übermaß besitzen und durch Schrumpfung, z. B. durch Kühlung mit flüssigem Wasserstoff, in das Metallprofil eingebracht werden. In beiden Fallen muß das Übermaß des Hohlprofils ausreichen, um die Klemmprofilleisten vollständig in die C-förmigen Ausbildungen einzupressen.When producing a metal profile according to the invention, it is essential that a tension is applied by oversizing the hollow body. The oversize can be generated by placing and expanding the hollow body between the clamp profile strips. The hollow body can already have an oversize in the initial state and by shrinkage, for. B. by cooling with liquid hydrogen, are introduced into the metal profile. In both cases, the oversize of the hollow profile must be sufficient to press the clamping profile strips completely into the C-shaped formations.

Besonders hohe Klemmwirkung hat sich mit folgender Legierung erzielen lassen:

Figure imgb0002
A particularly high clamping effect could be achieved with the following alloy:
Figure imgb0002

Aus dieser Legierung läßt sich ein Hohlprofil herstellen, das gut formbar, unelastisch und rückstellarm ist. Auch nach längerer Beanspruchung bleiben die güstigen Werte erhalten. Diese Legierung zeigt gegenüber Vergleichslegierungen nach der Aufweitung sehr hohe . Festigkeitswerte.A hollow profile can be produced from this alloy, which is easily formable, inelastic and has little resetting. The good values are retained even after prolonged use. This alloy shows very high compared to comparison alloys after expansion. Strength values.

Zur Herstellung eines geschweißten Hohlkörpers ist folgende Legierung geeignet:

Figure imgb0003
The following alloy is suitable for producing a welded hollow body:
Figure imgb0003

Zur Herstellung der Klemmprofilleisten werden die üblichen Materialien verwendet, die eine ausreichende Steifigkeit bzw. Biegefestigkeit besitzen.The usual materials are used to produce the clamping profile strips, which have sufficient rigidity or bending strength.

Die Klemmprofilleisten müssen allerdings so geschnitten sein, daß ihre Faserrichtung quer zur Achsrichtung des Hohlkörpers verläuft.However, the clamping profile strips must be cut so that their fiber direction is transverse to the axial direction of the hollow body.

Ferner muß, wie bereits im Zusammenhang mit Fig. 2 erläutert wurde, der Hohlkörper zur Erzielung einer ausreichend festen Klemmwirkung mit zackenförmigen Ausbildungen am äußeren Umfang versehen sein. Diese Ausbildungen greifen in die Faserstruktur der Klemmprofilleisten ein und geben dem Gesamtprofil die erforderliche Steifigkeit.Furthermore, as has already been explained in connection with FIG. 2, the hollow body must be provided with jagged designs on the outer circumference in order to achieve a sufficiently firm clamping effect. These designs intervene in the fiber structure of the clamping profile strips and give the overall profile the required rigidity.
