Abstract

1. 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.

Die Erfindung betrifft ein Verfahren zur Herstellung eines wärmegedämmten Verbundprofils, bestehend aus zwei Teilprofilstäben aus Metall, die an ihren einander gegenüberliegenden Seiten im Querschnitt C-förmig ausgebildet sind und an ihren C-Schenkeln jeweils eine Abwinkelung zur Bildung einer himerschnittenen Nut aufweisen, und aus zwei in die hinterschnittenen Nuten eingreifenden Klemmprofilleisten und einem zwischen ihnen angeordneten als Hohlkörper ausgebildeten starren, ein Übermaß aufweisenden Spreizkörper, der zur Verbindung der Teilprofilstäbe nur gegen die Klemmprufilleisten drückt und diese gegen die Teilprofilstäbe preßt.The invention relates to a method for producing a thermally insulated composite profile, consisting of two metal section bars attached to each other opposite sides are C-shaped in cross-section and each have one on their C-legs Have angled to form a ridge cut groove, and two in the undercut grooves engaging clamping profile strips and one arranged between them designed as a hollow body rigid, an excess having expansion body, which is used to connect the partial profile rods only against the Presses clamping profile bars and presses them against the profile bars.

Ein derartiges Verfahren ist durch die DE-OS 34 668 bekanntgeworden. Bei diesem Verfahren wird der Spreizkörper nachträglich eingepreßt, so daßSuch a method has become known from DE-OS 34 668. In this procedure, the expansion body subsequently pressed in, so that entweder der Spreizkörper selbst oder die Klemmprofilleisten elastisch ausgebildet sein müssen, da andernfalls der Spreizkörper nicht in seine Klemmlage gebracht werden kann. Dadurch wird die Verbindungeither the expansion body itself or the clamping profile strips must be designed to be elastic, since otherwise the expansion body cannot be brought into its clamping position. This will make the connection der Teilprofilstäbe immer etwas elastisch bleiben und die Steifigkeit des Verbundprofils herabgesetzt, da die Verbindung der Teilprofilstäbe nicht starr ist.the partial profile rods always remain somewhat elastic and the rigidity of the composite profile is reduced because the Connection of the sectional bars is not rigid.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren der eingangs genannten Art zu schaffen, beiThe invention is based on the object of creating a method of the type mentioned at the beginning

ίο dem die für das Einbringen des Spreizkörpers montagebedingte Elastizität entweder des Spreizkörpers oder der Klemmprofilleisten nicht erforderlich istίο the one for inserting the expansion body Assembly-related elasticity of either the expansion body or the clamping profile strips is not required is

Erfindungsgemäß wird dies dadurch erreicht, daß derAccording to the invention this is achieved in that the

Spreizkörper ohne Übermaß zwischen die Klemmprofilleisten eingeschoben und anschließend aufgeweitet wird.Spreader is inserted without oversize between the clamping profile strips and then expanded.

Durch das erfindungsgemäße Verfahren ist es möglich, neben einem starren Spreizkörper auch starreThe method according to the invention makes it possible to use a rigid expansion body as well as a rigid expansion body

Klemmprofilleisten zu verwenden, da das Übermaß des Spreizkörpers erst nach seinem Einbringen in die Klemmlage aufgebracht wird.To use clamping profile strips, since the oversize of the expansion body only after its introduction into the Clamping layer is applied.

Es ist vorteilhaft, den Spreizkörper im gekühlten Zustand zwischen die Klemmprofilleisten einzuIt is advantageous to use the expansion body in the cooled Condition between the clamping profile strips schieben. In diesem Fall weist der Spreizkörper im Ausgangszustand ein Übermaß auf, das durch Kühlung, z.B. mittels flüssigem Wasserstoff, so abgebaut wird, daß der Spreizkörper zwischen die Klemmprofilleisten eingebracht werden kann. Eine bevorzugte Ausfühpush. In this case, the expansion body in The initial state shows an excess, which is broken down by cooling, e.g. using liquid hydrogen, that the expansion body can be introduced between the clamping profile strips. A preferred execution rungsart des Verfahrens besteht ferner darin, daß für den Spreizkörper ein formbarer, rückstallarmer Werkstoff verwendet wird und der Spreizkörper mittels eines Ziehdorns aufgeweitet wird. Vorteilhafterweise kann am äußeren Umfang desThe method of approximation also consists in the fact that for the expansion body a malleable, low-resilience material is used and the expansion body by means of a Drawing mandrel is expanded. Advantageously, on the outer periphery of the Spreizkörpers eine zackenförmige Ausbildung vorgesehen sein. Als Material des Spreizkörpers wird bevorzugt eine Legierung der folgenden Zusammensetzung verwendet:Spreader body can be provided in a serrated configuration. The material of the expansion body is preferred an alloy of the following composition is used:

Aus dieser Legierung läßt sich ein Spreizkörper so herstellen, der gut formbar, unelastisch und rückstellarm ist. Auch nach längerer Beanspruchung bleiben die günstigen Werte erhaken. Diese Legierung zeigt gegenüber Vergleichslegierungen nach der Aufweitung sehr hohe Festigkeitswerte.An expansion body can be produced from this alloy in such a way that it is easily malleable, inelastic and has little resilience is. The favorable rates remain in place even after prolonged use. This alloy shows very high strength values compared to comparison alloys after expansion.
