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 wärmegedämmtes Metallprofil und ein Verfahren zu seiner Herstellung.The invention relates to a thermally insulated metal profile and a method for its production.

Es ist bekannt, die Wärmeisolierung von Metallprofilen dadurch zu verbessern, daß zwei Teilprofile mit einer wärmeisolierenden Zwischenschicht versehen werden. Diese kann durch Ausschäumung oder miteinander verbundene Zwischenlagen hergestellt werden.It is known to improve the thermal insulation of metal profiles in that two partial profiles are provided with a heat-insulating intermediate layer. This can be produced by foaming or by connecting intermediate layers.

Nach der DE-PS 12 45 568 ist ein Verbundprofilstab für Fensterflügelrahmen, Fensterrahmen oder dergleichen bekannt. Dieses besteht aus einem inneren und äußeren Metallprofilstab sowie aus einer wärmeisolierenden Zwischenlage aus zwei parallel zueinander verlaufenden Profilleisten, die miteinander verspannt sind. Durch diese Verspannung werden der innere und äußere Metallprofilstab wärmeisolierend miteinander verbunden.According to DE-PS 12 45 568, a composite profile bar for casement frames, window frames or the like is known. This consists of an inner and outer metal profile rod as well as a heat-insulating intermediate layer made of two profile strips that run parallel to each other and are braced together. This bracing connects the inner and outer metal profile bars to each other in a heat-insulating manner.

Der bekannte Verbundprofilstab läßt sich nur dort verwenden, wo die Zugänglichkeit für die Spannelemente gewährleistet ist. Da die Verspannung durch Druckschrauben aufgebracht wird, muß mindestens eine Seite des Verbundprofilstabes zu Montagezwecken frei bleiben.The known composite profile bar can only be used where the accessibility for the clamping elements is guaranteed. Since the bracing is applied by pressure screws, at least one side of the composite profile rod must remain free for assembly purposes.

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 in a heat-insulating manner.

Aufgabe der vorliegenden Erfindung ist es daher, ein wärmegedämmtes Metallprofil herzustellen, bei dem das wärmeisolierende Material ohne Rücksicht auf die Zugänglichkeit mit den Teilprofilstäben verspannt werden kann.The object of the present invention is therefore to produce a thermally insulated metal profile in which the heat-insulating material can be braced with the partial profile bars regardless of the accessibility.

Erfindungsgemäß wird diese Aufgabe durch die in den Patentansprüchen angegebenen Merkmale gelöst.According to the invention, this object is achieved by the features specified in the patent claims.

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 Feuchtigkeit.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:
  • 1 shows a cross section through the metal profile according to the invention with two partial profile bars arranged parallel to one another,
  • 2 cross section through a hollow body for fastening the clamping profile strips,
  • 3 longitudinal section through a metal profile according to F ig: 1 during the tensioning 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 which parallel arranged and insulated wall panels are 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.1 shows a metal profile according to the proposal of the invention, 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 Figure 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 Figure 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 entsteht. Die Klemmprofilleisten sind innerhalb der Doppelwand untergebracht, und die Hohlkörper können ohne Eingriff von der Wandseite her aufgeweitet werden. Falls ein vollständig geschlossener, doppelwandiger Behälter hergestellt werden soll, ist es vorteilhaft, dieVerbindungen durch Schrumpfung der Hohlkörper herzustellen. Dieses geschieht zweckmäßigerweise dadurch, daß die Hohlkörper vor dem Einschieben in die Klemmprofilleisten gekühlt werden.Fig. 5 shows a particularly advantageous application of the invention, in which a double-walled box profile is completely closed to the outside and inside. The clamping profile strips are housed within the double wall, and the hollow bodies can be expanded from the wall side without any intervention. If a completely closed, double-walled container is to be produced, it is advantageous to make the connections by shrinking the hollow bodies. This is expediently done in that the hollow bodies are cooled before being inserted into the clamping profile strips.

Fig. 6 zeigt ein weiteres,bevorzugtes Anwendungsbeispiel des erfindungsgemäßen Verfahrens. Hier wird eine Außenwand 1 an der Innenwand 2 durch das erfindungsgemäße Klemmsystem befestigt. Das Klemmsystem besteht aus einer Grundplatte 3, die mit der Außenwand 1 verschraubt ist. In der C-förmigen Ausbildung der Grundplatte 3 liegt das wärmeisolierende Material 4. Durch den Hohlkörper 5 wird das wärmeisolierende Material in den C-förmigen Ausbildungen der Grundplatte 3 und der gegenüberliegenden Verankerungsplatte 6 verspannt. Zur Sicherung bei höchster Beanspruchung sind Hakenprofile 7, 8 vorgesehen. 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 Klemm- profilleisten 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 Fällen muß das übermaß des Hohlprofils ausreichen, um die Klemmprofilleisten vollständig in die C-förmigen Ausbildungen einzupressen.6 shows a further, preferred application example of the method according to the invention. Here, an outer wall 1 is fastened to the inner wall 2 by the clamping system according to the invention. The clamping system consists of a base plate 3, which is screwed to the outer wall 1. The heat-insulating material 4 lies in the C-shaped design of the base plate 3. The heat-insulating material is braced by the hollow body 5 in the C-shaped designs of the base plate 3 and the opposite anchoring plate 6. Hook profiles 7, 8 are provided for securing under the highest loads. When producing a metal profile according to the invention, it is essential that a tension is applied by oversizing the hollow body. The interference can be generated by the fact that the hollow body between the K lemm- set profile strips and is expanded. However, the hollow body can already have an oversize in the initial state and can be introduced into the metal profile by shrinking, for example by cooling with liquid hydrogen. In both cases, the excess 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 imgb0001
A particularly high clamping effect was achieved with the following alloy:
Figure imgb0001

Aus dieser Legierung läßt sich ein Hohlprofil herstellen, das gut formbar, unelastisch und rückstellarm ist. Auch nach längerer Beanspruchung bleiben die günstigen 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 favorable values are retained even after prolonged use. This alloy shows very high strength values after expansion after comparison alloys. '

Zur Herstellung eines geschweißten Hohlkörpers ist folgende Legierung geeignet:

Figure imgb0002
Zur Herstellung der Klemmprofilleisten werden die üblichen Materialien verwendet, die eine ausreichende Steifigkeit bzw. Biegefestigkeit besitzen.The following alloy is suitable for producing a welded hollow body:
Figure imgb0002
 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 has to be provided with serrated 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.
