Introduced into the chamber (9) is a hollow profile (11) made of heat-insulating plastic which is closed on the end side and which bears with its outer sides essentially flush against the inner sides of the metal profile parts (2, 3) and of the plastic insulating webs (4, 5) and the inner cavity of which is evacuated for the purpose of preventing a heat-convection flow. <IMAGE>

Description

Die Erfindung betrifft ein Verbundprofil aus zwei Metallprofilteilen und zwei diese Teile miteinander verbindenden Kunststoffisolierstegen, die in Nuten der Metallprofilteile gehalten sind, wobei die Innenseiten der Metallprofilteile und der Kunststoffisolierstege eine in Längsrichtung des Verbundprofils durchgehend verlaufende Kammer von im wesentlichen rechteckigem Querschnitt begrenzen und in die Kammer ein Hohlprofil aus wärmeisolierendem Kunststoff eingebracht ist, das mit seinen Außenseiten im wesentlichen bündig an den Innenseiten der Metallprofilteile und der Kunststoffisolierstege anliegt.The invention relates to a composite profile made of two metal profile parts and two plastic insulating webs connecting these parts to one another, which are held in grooves in the metal profile parts, the insides of the metal profile parts and the plastic insulating webs delimiting a chamber of essentially rectangular cross section which runs continuously in the longitudinal direction of the composite profile and into the chamber a hollow profile made of heat-insulating plastic is introduced, the outer sides of which lie essentially flush with the inner sides of the metal profile parts and the plastic insulating webs.

Ein derartiges Verbundprofil ist aus DE-PS 12 14 375 (Fig. 5) bekannt. Das bei dem bekannten Profil in dessen Kammer angeordnete, durchgehende Kunststoffrohr ist weder stirnseitig verschlossen noch weist es Zwischenwände auf. Es ist ferner nicht evakuiert und nicht mit einem schlecht wärmeleitenden Gas gefüllt. Es besteht also bei diesem Verbundprofil kein Schutz gegen wärmetransportierende Konvektionsströmungen in der Kammer.Such a composite profile is known from DE-PS 12 14 375 (Fig. 5). The continuous plastic tube arranged in the chamber in the known profile is neither closed on the end face nor has intermediate walls. It is also not evacuated and is not filled with a poorly heat-conducting gas. With this composite profile there is no protection against heat-transporting convection currents in the chamber.

Aus DE-GM 80 12 220 (Fig. 3) ist ein aus relativ kurzen Teilstücken zusammensteckbares Hohlprofil mit quer verlaufenden Zwischenwänden bekannt. Dieses Hohlprofil tritt jedoch an die Stelle der Kunststoffisolierstege zwischen den Metallteilen des Verbundprofils, es ist also kein zusätzliches Hohlprofil. Die Zwischenwände dichten auch nicht den gesamten Innenraum des Hohlprofils ab, sondern sie sind einschließlich einer Abschlußwand im Abstand von den oberen und unteren Begrenzungen des Hohlprofils angeordnet, um so durchgehende Kanäle zu bilden, durch welche Spülflüssigkeit durchströmen kann. Die Wände des Hohlprofils umschließen "Luftkammern", also keine evakuierten Räume.DE-GM 80 12 220 (FIG. 3) discloses a hollow profile which can be plugged together from relatively short sections and has transverse partition walls. However, this hollow profile replaces the plastic insulating webs between the metal parts of the composite profile, so it is not an additional hollow profile. The partitions do not seal the entire interior of the hollow profile, but they are arranged, including an end wall, at a distance from the upper and lower boundaries of the hollow profile, so as to form continuous channels through which Flush liquid can flow through. The walls of the hollow profile enclose "air chambers", ie no evacuated rooms.

Es ist ferner generell bekannt (DE-US 25 10 060), bei Verbundprofilen die Kammer mit einem Kunststoff-Hartschaum zu füllen, der eine zusätzliche Wärmedämmung einschließlich Verhinderung einer Konvektionsströmung in der Kammer bewirkt. Das nachträgliche und gleichmäßige Einbringen eines Kunststoffhartschaumes in die Kammer ist jedoch nur unter Schwierigkeiten auszuführen, und zwar insbesondere deswegen, weil ein solches Verbundprofil eine Länge bis zu 6 m oder mehr haben kann. Außerdem wirft das Einbringen von Kunststoff in die Kammer Umweltverschmutzungsprobleme auf.It is also generally known (DE-US 25 10 060) to fill the chamber in the case of composite profiles with a plastic hard foam which brings about additional thermal insulation, including preventing a convection flow in the chamber. However, the subsequent and even introduction of a rigid plastic foam into the chamber is difficult to carry out, in particular because such a composite profile can have a length of up to 6 m or more. The introduction of plastic into the chamber also poses environmental pollution problems.

Es ist also Aufgabe der Erfindung, ein gattungsgemäßes Verbundprofil so auszubilden, daß wärmetransportierende Konvektionsströmungen in seiner Kammer verhindert sind, ohne daß diese vollständig mit einem Kunststoffschaum oder einem anderen Material gefüllt werden muß.It is therefore an object of the invention to design a generic composite profile so that heat-transporting convection currents are prevented in its chamber without this having to be completely filled with a plastic foam or another material.

Die Aufgabe wird erfindungsgemäß dadurch gelöst, daß das Hohlprofil stirnseitig verschlossen und der innere Hohlraum des Hohlprofils evakuiert und/oder mit einem Gas geringerer Wärmeleitfähigkeit als Luft gefüllt ist sowie durch quer zur Längsrichtung verlaufende Zwischenwände in einzelne Abschnitte unterteilt ist.The object is achieved in that the hollow profile is closed at the end and the inner cavity of the hollow profile is evacuated and / or filled with a gas having a lower thermal conductivity than air and is divided into individual sections by transverse walls running transversely to the longitudinal direction.

Die Figur 1 zeigt ein z.B. für die Herstellung von Fenstern, Türen, Fassadenelemente oder dgl. geeignetes Verbundprofil, welches eine Länge von 6 m oder mehr haben kann und zur Herstellung eines Fensters in entsprechende kürzere Abschnitte zerlegt wird. Das Verbundprofil 1 umfaßt ein inneres Metallprofilteil 2 und ein äußeres Metallprofilteil 3, beide z.B. aus Aluminium oder Aluminiumlegierung gefertigt. Die beiden Metallprofilteile 2, 3 sind durch längs verlaufende Kunststoffisolierstege 4, 5, z.B. aus glasfaserverstärkten Polyamiden miteinander verbunden. Die Kunststoffisolierstege 4, 5 bilden eine wärmedämmende Brücke zwischen den Metallprofilteilen 2, 3.FIG. 1 shows a composite profile suitable, for example, for the production of windows, doors, facade elements or the like, which can have a length of 6 m or more and is broken down into correspondingly shorter sections for the production of a window. The composite profile 1 comprises an inner metal profile part 2 and an outer metal profile part 3, both made of aluminum or aluminum alloy, for example. The two metal profile parts 2, 3 are connected to one another by longitudinal plastic insulating webs 4, 5, for example made of glass fiber reinforced polyamides. The plastic insulating webs 4, 5 form a heat-insulating bridge between the metal profile parts 2, 3.

Die Kunststoffisolierstege 4, 5 ragen mit ihren im Querschnitt schwalbenschwanzförmig ausgebildeten Enden 6 in entsprechend ausgebildete, längs verlaufende Nuten 7 der Metallprofilteile 2, 3 hinein, in denen sie durch entsprechendes Anwalzen der diese Nuten begrenzenden Wandschenkel 8 gehalten sind. Dabei bildet sich im fertigen Verbundprofil 1 zwischen den Innenseiten der Metallprofilteile 2, 3 und der Kunststoffisolierstege 4, 5 eine in Längsrichtung des Verbundprofils durchgehend verlaufende Kammer 9 aus.The plastic insulating webs 4, 5 protrude with their dovetail-shaped ends 6 in cross-section into appropriately designed, longitudinal grooves 7 of the metal profile parts 2, 3, in which they are held by appropriate rolling of the wall limbs 8 delimiting these grooves. In the finished composite profile 1, a chamber 9 running continuously in the longitudinal direction of the composite profile is formed between the inner sides of the metal profile parts 2, 3 and the plastic insulating webs 4, 5.

Die Kammer 9 ist normalerweise mit Luft gefüllt, so daß in ihr dann, wenn die Metallprofilteile 2, 3 unterschiedliche Temperaturen aufweisen, störende Konvektionsströmungen auftreten können, welche Wärme zwischen den Metallprofilteilen 2, 3 hin- und hertransportieren. Dies ist dann höchst unerwünscht, wenn aus dem Verbundprofil 1 beispielsweise ein Fensterrahmen hergestellt ist, weil dann Wärmeverluste von der Innen- zur Außenseite des Fensters hin auftreten können.The chamber 9 is normally filled with air, so that when the metal profile parts 2, 3 have different temperatures, disturbing convection currents can occur, which transport heat back and forth between the metal profile parts 2, 3. This is highly undesirable if, for example, a window frame is made from the composite profile 1 because heat losses can then occur from the inside to the outside of the window.

Zur Vermeidung wärmetransportierender Konvektionsströmungen in der Kammer 9 des Verbundprofils 1 wird erfindungsgemäß in diese Kammer ein stirnseitig verschlossenes Hohlprofil 11 durchgehend eingebracht, das mit seinen Außenseiten im wesentlichen bündig an den Innenseiten der Metallprofilteile 2, 3 und der Kunststoffisolierstege 4, 5 anliegt. In Fig. 1 ist eine stirnseitige Verschlußwand 12, die gegenüber der Schnittstelle des Verbundprofils etwas zurückgesetzt ist, zum Teil strichpunktiert angedeutet. Eine entsprechende Verschlußwand ist auch an der (in Fig. 1 nicht dargestellten) Rückseite des Verbundprofils 1 vorgesehen. Der innere Hohlraum des stirnseitig verschlossenen Hohlprofils 11 ist evakuiert. Hierdurch ist die Ausbildung von wärmetransportierenden Konvektionsströmungen im Innenraum des Hohlprofils 11 verhindert, so daß hierdurch auch kein Wärmeausgleich zwischen den Metallprofilteilen 2 und 3 stattfinden kann.In order to avoid heat-transporting convection flows in the chamber 9 of the composite profile 1, a hollow profile 11, which is closed at the end, is continuously introduced into this chamber Outside is essentially flush against the inside of the metal profile parts 2, 3 and the plastic insulating webs 4, 5. In Fig. 1, an end closure wall 12, which is set back somewhat from the interface of the composite profile, is partially indicated by dash-dotted lines. A corresponding closure wall is also provided on the back of the composite profile 1 (not shown in FIG. 1). The inner cavity of the hollow profile 11, which is closed at the end, is evacuated. This prevents the formation of heat-transporting convection flows in the interior of the hollow profile 11, so that no heat compensation between the metal profile parts 2 and 3 can take place as a result.

Die Erzeugung des Vakuums im inneren Hohlraum des Hohlprofils 11 kann beispielsweise dadurch erfolgen, daß an der Verschlußwand 12 eine entsprechende Bohrung angebracht wird, die mit einer Vakuumpumpe verbunden wird. Nach Erzeugung des Vakuums wird diese Bohrung dicht verschlossen.The vacuum in the inner cavity of the hollow profile 11 can be generated, for example, in that a corresponding hole is made in the closure wall 12 and is connected to a vacuum pump. After the vacuum is created, this hole is sealed.

Es genügt grundsätzlich, ein auf die gewünschte Länge zugeschnittenes Verbundprofilteil 1 lediglich an seiner vorderen und hinteren Stirnseite durch eine Verschlußwand 12 zu verschließen. Vorteilhafter ist es, bei der Herstellung eines Verbundprofils 1 größerer Länge (beispielsweise 6 m oder mehr) den inneren Hohlraum des Hohlprofils 11 durch quer zur Längsrichtung des Verbundprofils verlaufende Zwischenwände 13 in einzelne evakuierte Abschnitte zu unterteilen. Derartige Zwischenwände 13 sind in Fig. 1 strichpunktiert angedeutet. Die Zwischenwände 13 sollen einen möglichst kleinen Abstand voneinander haben, so daß beim Zerteilen des Verbundprofils 1 in Abschnitte kleinerer Länge im wesentlichen möglichst der gesamte Abschnitt zwischen den an ihm ausgebildeten Schnittflächen evakuiert ist.It is basically sufficient to close a composite profile part 1 cut to the desired length only on its front and rear end sides by a closure wall 12. It is more advantageous in the manufacture of a composite profile 1 of greater length (for example 6 m or more) to divide the inner cavity of the hollow profile 11 into individual evacuated sections by intermediate walls 13 running transversely to the longitudinal direction of the composite profile. Such partition walls 13 are indicated by dash-dotted lines in FIG. 1. The intermediate walls 13 should have the smallest possible distance from one another, so that when the composite profile 1 is divided into sections of shorter length, essentially the entire section between the cut surfaces formed on it is evacuated.

Ein mit Zwischenwänden 13 versehenes Hohlprofil 11 kann in herkömmlicher Weise extrudiert und dabei gleichzeitig oder unmittelbar danach evakuiert werden.A hollow profile 11 provided with partition walls 13 can be extruded in a conventional manner and evacuated simultaneously or immediately thereafter.

Die Figur 2 zeigt eine Teil-Querschnittansicht des Verbundprofils 1 aus Fig. 1 mit noch nicht aneinander befestigten Bestandteilen des Verbundprofils. Man erkennt aus Fig. 2, die in Draufsicht auch eine Zwischenwand 13 zeigt, daß die Wandschenkel 8, welche die Nuten 7 in den Metallprofilteilen 2, 3 begrenzen, noch nach der entgegengesetzten Richtung wie in Fig. 1, also nach außen abstehen, so daß die Kunststoffisolierstege 4, 5 mit ihren schwalbenschwanzförmig verdickten Enden leicht in die Nuten 7 eingesetzt, beispielsweise längsweise eingezogen werden können. Zwischen die Metallprofilteile 2, 3 und die Kunststoffisolierstege 4, 5 ist lose das vorgeformte Hohlprofil 11 eingesetzt, beispielsweise ebenfalls längsweise eingeschoben. Wenn nunmehr, ausgehend von dem in Fig. 2 dargesetellten Zustand des Verbundprofils die jeweils außen liegenden Wandschenkel 8 durch Anwalzen oder Anpressen nach einwärts gebogen werden, werden hierdurch die Metallprofilteile 2, 3 und die Kunststoffisolierstege 4, 5 form- und kraftschlüssig fest zusammengespannt, wodurch auch das Hohlprofil 11 einen festen Sitz in der Kammer 9 erfährt, wobei das Hohlprofil 11 mit seinen Außenseiten im wesentlichen bündig an den Innenseiten der Metallprofilteile 2, 3 und der Kunststoffisolierstege 4, 5 anliegt. Dieser Zustand ist in Fig. 3 dargestellt.FIG. 2 shows a partial cross-sectional view of the composite profile 1 from FIG. 1 with components of the composite profile that have not yet been attached to one another. It can be seen from Fig. 2, which also shows an intermediate wall 13 in plan view, that the wall legs 8, which delimit the grooves 7 in the metal profile parts 2, 3, still protrude outward in the opposite direction as in Fig. 1, so that the plastic insulating webs 4, 5 with their dovetailed ends are easily inserted into the grooves 7, for example can be drawn in lengthwise. The preformed hollow profile 11 is loosely inserted between the metal profile parts 2, 3 and the plastic insulating webs 4, 5, for example also inserted lengthways. If, starting from the state of the composite profile shown in FIG. 2, the respective outer wall legs 8 are bent inwards by rolling or pressing, the metal profile parts 2, 3 and the plastic insulating webs 4, 5 are thereby firmly and positively clamped together, thereby the hollow profile 11 also has a firm fit in the chamber 9, the outer sides of the hollow profile 11 being essentially flush with the inner sides of the metal profile parts 2, 3 and the plastic insulating webs 4, 5. This state is shown in Fig. 3.

Man kann das Hohlprofil 11 in seiner Querschnittsfläche auch etwas größer als die Querschnittsfläche der Kammer 9 ausbilden, so daß das Hohlprofil 11 beim Anwalzen der Wandschenkel 8 kraftschlüssig in das Verbundprofil 1 eingespannt wird.The cross-sectional area of the hollow profile 11 can also be made somewhat larger than the cross-sectional area of the chamber 9, so that the hollow profile 11 is clamped non-positively into the composite profile 1 when the wall legs 8 are rolled on.

Andererseits ist es auch möglich, bei dem in Fig. 2 dargestellten, noch nicht zusammengebauten Zustand des Verbundprofils 1 das Hohlprofil 11 mit seiner Unterseite auf der Oberseite des Metallprofilteils 2, beispielsweise durch Verklebung zu fixieren.On the other hand, it is also possible, in the not yet assembled state of the composite profile 1 shown in FIG. 2, to fix the hollow profile 11 with its underside on the top of the metal profile part 2, for example by gluing.

Bei der in Fig. 4 dargestellten Ausführungsform ist das Hohlprofil 11 mit seinen Zwischenwänden 13 seitlich fest mit den Kunststoffisolierstegen 4, 5, beispielsweise durch Verklebung oder Verschweißung verbunden. In Fig. 5 sind die Kunststoffisolierstege 4, 5 und das Hohlprofil 11, z.B. durch Extrusion von vornherein einstückig ausgebildet. Sowohl im Falle der Fig. 4 als auch im Falle der Fig. 5 bilden die Kunststoffisolierstege 4, 5 und das Hohlprofil 11 ein vorgefertigtes Bauteil.In the embodiment shown in FIG. 4, the hollow profile 11 with its intermediate walls 13 is laterally firmly connected to the plastic insulating webs 4, 5, for example by gluing or welding. In Fig. 5 the plastic insulating webs 4, 5 and the hollow profile 11, e.g. formed in one piece from the outset by extrusion. Both in the case of FIG. 4 and in the case of FIG. 5, the plastic insulating webs 4, 5 and the hollow profile 11 form a prefabricated component.

Bei der in Fig. 6 in Längsschnittansicht dargestellten Ausführungsform ist das in die Kammer 9 des Verbundprofils 1 einzubringende Hohlprofil 111 aus relativ kurzen, quaderförmigen, hohlen Teilstücken 15 zusammengesetzt, an denen jeweils eine quer verlaufende Zwischenwand 16 ausgebildet ist. Wie dargestellt, sind die einzelnen Teilstücke 15 an ihrem einen, der Zwischenwand 16 benachbarten Enden abgestuft ausgebildet, so daß sie jeweils in ein in Längsrichtung vorangehendes Teilstück 15 eingesteckt werden können. Falls erwünscht, können die einzelnen Teilstücke 15 mit Hilfe von Dichtungen 17 gegenseitig abgedichtet werden. Die durch das Zusammensetzen der Teilstücke 15 hintereinander gebildeten Einzelhohlräume 18 des Hohlprofils 111 können, beispielsweise in der oben beschriebenen Art und Weise, evakuiert werden. Wenn ein Verbundprofil 1 mit einer Länge von beispielsweise 6 bis 8 m ein Hohlprofil 111 gemäß Fig. 6 enthält, kann es, beispielsweise bei der Herstellung eines Fensters, in entsprechend kurze Abschnitte zerlegt werden, wobei im wesentlichen über die gesamte Länge des Abschnittes hinweg das evakuierte Hohlprofil 111 erhalten bleibt. Lediglich an den abgeschnittenen Stirnflächen des Abschnittes können infolge des Durchtrennens der Teilstücke 15 relativ kurze Hohlräume auftreten, die nicht evakuiert sind.In the embodiment shown in FIG. 6 in a longitudinal sectional view, the hollow profile 111 to be introduced into the chamber 9 of the composite profile 1 is composed of relatively short, rectangular, hollow sections 15, on each of which a transverse partition 16 is formed. As shown, the individual sections 15 are stepped at their one end, which is adjacent to the intermediate wall 16, so that they can each be inserted into a section 15 preceding in the longitudinal direction. If desired, the individual sections 15 can be mutually sealed with the aid of seals 17 will. The individual cavities 18 of the hollow profile 111 formed by the assembly of the sections 15 one behind the other can be evacuated, for example in the manner described above. If a composite profile 1 with a length of, for example, 6 to 8 m contains a hollow profile 111 according to FIG. 6, it can be broken down into correspondingly short sections, for example in the manufacture of a window, the essentially over the entire length of the section evacuated hollow section 111 is retained. Only on the cut end faces of the section can relatively short cavities occur due to the severing of the sections 15, which are not evacuated.

Die in Fig. 7 dargestellte Ausführungsform entspricht grundsätzlich derjenigen aus Fig. 6. Im Unterschied zu Fig. 6 weisen in Fig. 7 allerdings die zu einem Hohlprofil 211 zusammengesetzten Teilstücke 15 außer der in der Nähe der Abstufung angeordneten Zwischenwand 16 an den gegenüberliegenden Enden zusätzliche Zwischenwände 19 auf, so daß jedes Teilstück 15 für sich, auch in noch nicht zum Hohlprofil 211 zusammengesetzten Zustand evakuiert werden kann. Das Hohlprofil 211 ist also aus von vornherein evakuierten Teilstücken zusammengesetzt.The embodiment shown in FIG. 7 basically corresponds to that from FIG. 6. In contrast to FIG. 6, however, in FIG. 7 the sections 15 assembled to form a hollow profile 211 have additional ones at the opposite ends apart from the intermediate wall 16 arranged near the step Partitions 19 on, so that each section 15 can be evacuated by itself, even in the state not yet assembled to form the hollow profile 211. The hollow profile 211 is therefore composed of sections evacuated from the outset.

Die Fig. 8 zeigt schaubildlich eine weitere Ausführungsform, bei welcher an denjenigen Außenseitenflächen eines Hohlprofils 311, die beim Einfügen in die Kammer 9 des Verbundprofils 1 mit den Innenseiten der Metallprofilteile 2, 3 beziehungsweise der Kunststoffisolierstege 4, 5 in Berührung gelangen, ein Kleber 21 aufgebracht ist, der auf Druck, Feuchte, oder Hitze reagiert und auch gegebenenfalls aufschäumbar ist. Wie dargestellt, weist das Hohlprofil 311 an seinen Außenseiten in Längsrichtung verlaufende Nuten 22 auf, in welche der Kleber 21 eingebracht ist.8 shows a diagram of a further embodiment, in which an adhesive 21 is provided on those outer side surfaces of a hollow profile 311 which come into contact with the inner sides of the metal profile parts 2, 3 or the plastic insulating webs 4, 5 when inserted into the chamber 9 of the composite profile 1 upset is that reacts to pressure, moisture or heat and can also be foamable. As shown, the hollow profile 311 has on its outer sides longitudinal grooves 22, into which the adhesive 21 is introduced.

Durch den aktivierten Kleber 21 kann das in der beschriebenen Weise evakuierte Hohlprofil 311 fest in die Kammer 9 des Verbundprofils 1 eingeklebt werden.Through the activated adhesive 21, the hollow profile 311 evacuated in the manner described can be firmly glued into the chamber 9 of the composite profile 1.

Im Voranstehenden wurde stets angenommen, daß die Hohlkammerprofile 11, 111, 211, 311 zur Vermeidung einer wärmetransportierenden Konvektionsströmung evakuiert sind. Grundsätzlich ist es bei einer abgewandelten Ausführungsform der Erfindung auch möglich, in die normalerweise evakuierten, inneren Hohlräume dieser Hohlprofile ein Gas mit möglichst niedriger Wärmeleitfähigkeit einzubringen. Auch hierdurch kann der Wärmetransport durch Konvektionsströmung weitgehend herabgesetzt werden. Geeignete Gase sind z.B. Xenon, Krypton, Brom, die alle eine geringere Wärmeleitfähigkeit als Luft haben.In the foregoing it was always assumed that the hollow chamber profiles 11, 111, 211, 311 were evacuated to avoid a heat-transporting convection flow. Basically, in a modified embodiment of the invention, it is also possible to introduce a gas with the lowest possible thermal conductivity into the normally evacuated inner cavities of these hollow profiles. This also largely reduces the heat transport by convection flow. Suitable gases are e.g. Xenon, krypton, bromine, all of which have a lower thermal conductivity than air.

Das Hohlprofil 11, 111, 211, 311 kann außen auch mit Metall, z.B. Aluminiumfolie, beschichtet werden. Hierdurch wird infolge Reflexion eine Wärmestrahlung zwischen den Metallprofilteilen 2, 3 reduziert.The hollow profile 11, 111, 211, 311 can also be covered with metal, e.g. Aluminum foil to be coated. As a result, heat radiation between the metal profile parts 2, 3 is reduced as a result of reflection.

Bei der Ausführungsform nach Fig. 9 sind im (evakuierten) Hohlprofil 11 sich kreuzende, längsweise verlaufende Versteifungsstege 31, 32 ausgebildet, die den äußeren, auf das Profil 11 einwirkenden Druck auffangen und ein Zusammenfallen des Profils 11 verhindern. Solche Versteifungsstege 31, 32 können auch bei den Hohlprofilen 111, 211 und 311 vorgesehen werden.In the embodiment according to FIG. 9, crosswise, longitudinally extending stiffening webs 31, 32 are formed in the (evacuated) hollow profile 11, the outer ones absorb the pressure acting on the profile 11 and prevent the profile 11 from collapsing. Such stiffening webs 31, 32 can also be provided for the hollow profiles 111, 211 and 311.
