Definitions
- the invention relates to a method for producing a composite profile according to the preamble of claim 1. Furthermore The invention relates to composite profiles as such, in particular produced by the method according to claim 1.
- a generic method for producing a composite profile is known from DE 30 42 838 A1. But lie down the partitions formed by the garlands do not touch the metal profile parts so that no perfect thermal insulation is ensured is.
- DE 30 01 402 describes a composite profile, which is obviously rigid, garland-like Plastic part between the metal profile parts of the composite profile is glued in. A cross-sectional change in this Plastic part by pulling apart is not provided, although this plastic profile is on every wall Chamber can create that from the inside of the metal profile parts and second plastic insulating webs is formed. From AT 372 491 finally a composite profile is known, in which in the chamber of the profile is a thin-walled, non-load-bearing plastic profile is inserted. This plastic profile lies not on the insulating bars and mediates none Subdivision of the chamber in the longitudinal direction of the profile, so that too here the thermal insulation is limited.
- the task is in a generic method by features in the characterizing part of claim 1 solved.
- the subclaims 4 to 11 relate to composite profiles, those according to such methods according to one of claims 1 to 3 are manufactured.
- claim 12 relates to a composite profile, which also uses a garland that is in their shape is changeable.
- the overall advantage of the invention is that the individual, self-contained, formed by the garland Chamber sections are so small that a disturbing heat convection in them can not take place, this is in the manufacturing process of the composite profile can be achieved in a very simple manner is.
- Figure 1 shows a z. B. for the production of windows, Doors, facade elements or the like suitable composite profile 1 with an inner metal profile part 2 and an outer metal profile part 3, both e.g. made of aluminum or aluminum alloy.
- the two Metal profile parts 2, 3 are by longitudinal Plastic insulating bars 4, 5, e.g. made of glass fiber reinforced Polyamides bonded together.
- the plastic insulating bars 4,5 form a heat-insulating bridge between the metal profile parts 2, 3.
- the plastic insulating webs 4, 5 project with their cross section Dovetail-shaped ends 6 in appropriately trained, longitudinal grooves 7 of Metal profile parts 2, 3, in which they by appropriate Rolling the wall limbs 7 delimiting these grooves 8 are held. It forms in the finished Composite profile 1 between the inside of the metal profile parts 2, 3 and the plastic insulating webs 4, 5 one in Longitudinal direction of the composite profile running continuously Chamber 9 out.
- the chamber 9 is in that of FIG. 1 and 2 obvious ways with a heat-insulating, flexible, wavy "garland" 11 filled.
- This garland is so wide that it on both sides of the inside of the insulating webs 4, 5 creates. Furthermore it lies with its "wave valleys” 12 and “wave crests” 13 at the bottom and top on the inside of the metal profile parts 2 or 3.
- the transverse dimension of the garland 11 is exactly the transverse dimension the chamber 9 between the insides of the plastic insulating webs 4, 5 corresponds and these pages can therefore nestle close to these insides.
- the garland 11 can also in the last mentioned cross direction the garland before it is introduced into the chamber 9 over the relevant cross-sectional dimension protrude from the chamber and only after they have been pulled apart experience such a deformation that their elements also on the inside of the plastic insulating bars 4, 5 nestle.
- the garland 11 could otherwise be in the chamber 9 be introduced that their troughs 12 and Wave crests 13 not on the inside of the metal profile parts 2, 3, but on the inside of the plastic insulating bars 4, 5 put on. In this way too desired, small chamber sections arise, one unwanted convection flow inside the chamber 9 counteract.
- the garland 11 does not necessarily have to be wavy be trained. You could also zigzag for example or folded in any other way, as long as it is ensured that they pull the desired apart Seals on the inside of the chamber 9 and so the individual chamber sections 14 realized.
- the flexible elements 15, which the troughs 12 and Can connect wave crests 13 of the garland as flexible threads, tapes or flat sheet or Foil parts can be formed.
- individual elements are more variable Cross dimension, for example flexible, cylindrical structures 16 together by connecting links 17 in the longitudinal direction connected.
- the links can in turn as flexible threads, tapes or flat film or Leaf parts should be formed.
- Fig. 7th shown shape i.e. those deformed circularly in FIG. 6
- Elements 16 have been introduced into the chamber 9 is an oval configuration, which moves into transformed the circular shape shown in Fig. 6.
- the elements 10 and 11 are individual transverse to the longitudinal direction of the composite profile 1 and the chamber 9 running, leaf-shaped elements 18 by flexible, first slack (Fig. 11) links 19 together connected.
- the elements 18 can be introduced before the Garland in the chamber 9 across its cross-sectional area protrude.
- the edges of the elements bend 18 accordingly and convey a close concern to the relevant inside of the chamber 9.
- the elements 18 can be designed so that all of their four boundary edges in the manner shown in FIG Nestle against the adjacent chamber walls accordingly kill.
- FIGS. 12 and 13 that is actual, wave-shaped garland element 21 with flexible elements, e.g. Threads 22, 23, in particular connected by intertwining.
- the garland element 21 and / or which form a further garland component Threads 22, 23 consist of a by heat, radiation or chemically expandable or erectable material, e.g. Epoxy, phenolic or polyester resin.
- the garland is first loose in the manner shown in FIG. 13 introduced into the chamber 9. Then the expansion takes place or erection, so that finally the one shown in Fig. 12 Condition is reached in which the garland to the inside of the chamber 9 with the formation of separate Chamber sections nestled.
- FIG. 14 and 15 show a garland consisting of a consists of two layers of flexible laminate, each layer made from a zigzag folded Garland section 24 or 25, which by a flexible central web 26 are interconnected.
- the 13 shows the garland designed as a laminate according to FIG Fig. 12 before their introduction into the chamber 9 of the composite profile 1.
- the garland as a laminate, which consists of more than three layers, the Layering can also run in two dimensions.
- FIG. 16 and 17 show a further preferred embodiment an insulating garland.
- This garland exists according to Fig. 17 before their introduction into the Chamber 9 from a flexible lower band 27 and one flexible upper band 28 formed by crossbars 29 such are interconnected, dap chamber sections with parallelogram-shaped cross section arise.
- the width the crossbars 29 corresponds to the distance between the Inside of the plastic insulating bars 4, 5.
- the chamber 9 are drawn. Will on the top and lower bands 27, 28 a train in the direction of the arrows shown A or B exercised, the crossbars are aligned 29 inside the chamber 9 in FIG. 16 visible way, so that the garland is now also hugs the inside of the metal profile parts 2, 3 and the chamber 9 into individual, separate Chamber sections is divided.
- FIG. 16 and 17 serve for illustration at the same time a further embodiment of the invention, the otherwise also refer to the previously described embodiments can be applied.
- Fig. 17 by the little ones Circles 31 indicated, is that forming the garland Material impregnated with an inflatable plastic or coated, i.e. with a plastic that is known in Way, a blowing agent, for example t-butylhydrazine chloride and contains ferric chloride.
- Suitable for this Plastics are e.g. unsaturated polyester resin, Phenolic or melamine resin, polyurethane, polypropylene or Polyethylene.
- the blowing agent is activated, so that the plastic expands and the individual Chamber sections of the garland completely filled. In this way there is also a convection flow in the individual chamber sections prevented. At the same time so the garland is transformed into a completely rigid form that also consolidate the composite profile can contribute. It is possible on this or a similar one Way to harden the garland into a rigid structure and stiffen that alone or in combination with those who may be less well trained - Plastic insulating webs 4, 5 is able to static requirements for the composite profile (in particular Shear and transverse tensile strength).
- FIGS. 2, 4, 6, 8, 10, 12, 14 and 16 are not a longitudinal sectional view but a cross sectional view of the composite profile 1, with a special 16, 17 is used, the chamber sections completely filled with foamed plastic are.
- Embodiment of the composite profile 1 are in the embodiment 18 the two profile parts 2, 3 not through individual plastic insulating webs 4, 5 with each other connected. Rather, in Fig. 18 these are plastic insulating bars 4, 5 by crossbars 32, 33, in one piece interconnected, so that a total of a so-called "Hollow chamber web" is formed.
- the chamber 9 is completely enclosed by this hollow chamber web and the plastic-filled garland is in the chamber in Introduced inside this web.
- the garland after moving into chamber 9 with at least to firmly connect an inside of the chamber.
- the described embodiments of flexible garlands 11 forming material can be plastic, cardboard, Paper or another fiber from natural and / or synthetic fibers, or from a textile fabric or knitted fabric, or mixtures thereof, wherein especially porous materials are used when the Garland in the manner described with adhesive or expandable plastic to be impregnated.
- a composite profile according to FIG a heat-insulating garland 11 in its chamber 9 advantageously be made as follows: one connects the (erect) garland 11 - for example by Bonding - firmly with at least one of the metal profile parts 2, 3 or the plastic insulating bars 4, 5. Then the plastic insulating bars 4, 5 into the metal profile parts 2, 3 used. Eventually the dovetail-shaped Ends of the plastic insulating webs 4, 5 rolled into the grooves 7 of the metal profile parts 2, 3.
- connection of the plastic insulating webs 4, 5 with the Garland 11 can also be done by this Bars 4, 5 sprayed onto the garland 11. If a garland Applied, which in turn by pultrusion or extrusion can be made is one Injection particularly cheap, the injection in Line or in a subsequent operation can. Instead of the plastic insulating bars on the garland injection, they can also be extruded or pulverized will.
- the garland unilaterally in the chamber for example on the inside of the metal profile part 2 fix and then pull in the direction of arrow B (Fig. 17) erect.

Description
Die Erfindung betrifft ein Verfahren zum Herstellen eines Verbundprofils
nach dem Oberbegriff des Patentanspruchs 1. Ferner
betrifft die Erfindung Verbundprofile als solche, insbesondere
hergestellt nach dem Verfahren gemäß Anspruch 1.The invention relates to a method for producing a composite profile
according to the preamble of
Ein gattungsgemäßes Verfahren zum Herstellen eines Verbundprofils ist aus der DE 30 42 838 A1 bekannt. Dabei legen sich aber die von den Girlanden gebildeten Zwischenwände nicht an die Metallprofilteile an, so daß keine vollkommene Wärmedämmung sichergestellt ist. In der DE 30 01 402 ist ein Verbundprofil beschrieben, bei dem ein offensichtlich starres, girlandenähnliches Kunststoffteil zwischen die Metallprofilteile des Verbundprofils eingeklebt wird. Eine Querschnittsveränderung dieses Kunststoffteils durch Auseinanderziehen ist nicht vorgesehen, obwohl sich dieses Kunststoffprofil allseits an die Wände einer Kammer anlegen kann, die von den Innenseiten der Metallprofilteile und zweiter Kunststoffisolierstege gebildet wird. Aus AT 372 491 schließlich ist ein Verbundprofil bekannt, bei dem in die Kammer des Profils ein dünnwandiges, nichttragendes Kunststoffprofil eingeschoben ist. Dieses Kunststoffprofil liegt nicht an den Isolierstegen an und vermittelt im übrigen keine Unterteilung der Kammer in Profillängsrichtung, so daß auch hier die Wärmedämmung begrenzt ist.A generic method for producing a composite profile is known from DE 30 42 838 A1. But lie down the partitions formed by the garlands do not touch the metal profile parts so that no perfect thermal insulation is ensured is. DE 30 01 402 describes a composite profile, which is obviously rigid, garland-like Plastic part between the metal profile parts of the composite profile is glued in. A cross-sectional change in this Plastic part by pulling apart is not provided, although this plastic profile is on every wall Chamber can create that from the inside of the metal profile parts and second plastic insulating webs is formed. From AT 372 491 finally a composite profile is known, in which in the chamber of the profile is a thin-walled, non-load-bearing plastic profile is inserted.

Es ist Aufgabe der Erfindung, ein gattungsgemäßes Verfahren so zu gestalten, daß die Wärmedämmung des Verbundprofils verbessert wird.It is an object of the invention, a generic method like this to design that improves the thermal insulation of the composite profile becomes.
Die Aufgabe wird bei einem gattungsgemäßen Verfahren durch die
im kennzeichnenden Teil des Patentanspruchs 1 stehenden Merkmale
gelöst.The task is in a generic method by
features in the characterizing part of
Bevorzugte Ausführungsformen dieses Verfahrens sind Gegenstand
der Unteransprüche 2 und 3. Preferred embodiments of this method are the subject

ihrer Gestalt veränderlich ist.Finally,
Durch die Erfindung wird insgesamt der Vorteil erzielt, daß die einzelnen, von der Girlande gebildeten, in sich geschlossenen Kammerabschnitte so klein sind, daß in ihnen eine störende Wärmekonvektion nicht stattfinden kann, wobei dies bei dem Herstellverfahren des Verbundprofils auf sehr einfache Weise erzielbar ist.The overall advantage of the invention is that the individual, self-contained, formed by the garland Chamber sections are so small that a disturbing heat convection in them can not take place, this is in the manufacturing process of the composite profile can be achieved in a very simple manner is.
Die nachstehende Beschreibung bevorzugter Ausführungsformen der Erfindung dient im Zusammenhang mit beiliegender Zeichnung der weiteren Erläuterung. Es zeigen:
Figur 1- eine schaubildliche Ansicht eines Verbundprofils für Fenster, Türen, Fassadenelemente oder dergleichen und

vor und nach ihrer Einbringung in eine
Kammer des Verbundprofils nach

- Figure 1
- a perspective view of a composite profile for windows, doors, facade elements or the like and
- Figure 2-18
- schematic views of thermal insulation garlands before and after their introduction into a chamber of the composite profile according to FIG. 1.
Die Figur 1 zeigt ein z. B. für die Herstellung von Fenstern,
Türen, Fassadenelementen oder dergleichen
geeignetes Verbundprofil 1 mit einem inneren Metallprofilteil
2 und einem äußeren Metallprofilteil 3, beide z.B.
aus Aluminium oder Aluminiumlegierung gefertigt. Die beiden
Metallprofilteile 2, 3 sind durch längsverlaufende
Kunststoffisolierstege 4, 5, z.B. aus glasfaserverstärkten
Polyamiden, miteinander verbunden. Die Kunststoffisolierstege
4,5 bilden eine wärmedämmende Brücke zwischen
den Metallprofilteilen 2, 3.Figure 1 shows a z. B. for the production of windows,
Doors, facade elements or the like
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 7 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
Obwohl die Kunststoffisolierstege 4, 5 wegen ihrer
schlechten Wärmeleiteigenschaften einen direkten Wärmeübergang
infolge Wärmeleitung zwischen den Metallprofilteilen
2, 3 verhindern, ist es doch möglich, daß dann,
wenn die beiden Metallprofilteile 2, 3 unterschiedliche
Temperaturen aufweisen, das in der Kammer 9 enthaltende
Gas, gewöhnlich Luft, zu Konvektionsströmungen veranlaßt
wird, die einen unerwünschten und störenden Wärmetransport
zwischen den Metallprofilteilen 2, 3 bewirken, so daß beispielsweise
durch diese Konvektion Wärme vom einen auf das
andere Metallprofilteil übertragen wird und hierdurch ein
unerwünschter Temperaturausgleich stattfindet.Although the
Um dies zu verhindern, ist die Kammer 9 in der aus Fig. 1
und 2 ersichtlichen Weise mit einer wärmedämmenden,
flexiblen, in einer Wellenlinie verlaufenden "Girlande" 11
gefüllt. Diese Girlande hat eine solche Breite, daß sie
sich beidseits an die Innenseiten der Isolierstege 4, 5
anlegt. Weiterhin liegt sie mit ihren "Wellentälern" 12
und "Wellenbergen" 13 unten bzw. oben an den Innenseiten
der Metallprofilteile 2 bzw. 3 an. Hierdurch entstehen in
der Kammer 9 einzelne, voneinander getrennte Kammerabschnitte
14. Es hat sich gezeigt, daß in diesen relativ
kleinen Kammerabschnitten praktisch keine Konvektionsströmung
mehr stattfinden kann, die zu einem störenden
Wärmeübergang zwischen den Metallprofilteilen 2, 3 führen
könnte.In order to prevent this, the
Die Fig. 3 zeigt die Girlande 11 vor ihrer Einbringung in
die Kammer 9. Wie ersichtlich, hat die Girlande in dem
dargestellten "zusammengeschobenen" Zustand in der quer
zur Längsrichtung zwischen den Metallprofilteilen 2, 3
verlaufenden Querdimension eine größere Ausdehnung als die
Höhe der Kammer 9 zwischen den Metallprofilteilen 2, 3.
Durch Auseinanderziehung der Girlande 11 bei ihrem Einbringen
in die Kammer 9 verringert sich diese Querdimension
entsprechend, so daß sich die Wellentäler 12 und
Wellenberge 13 dann an die jeweiligen Innenseiten der Metallprofilteile
2, 3 dicht anschmiegen.3 shows the
Bei der Ausführungsform gemäß Fig. 2 und 3 ist angenommen,
daß die Querdimension der Girlande 11 genau der Querabmessung
der Kammer 9 zwischen den Innenseiten der Kunststoffisolierstege
4, 5 entspricht und sich diese Seiten
daher dicht an diese Innenseiten anschmiegen können. Bei
anderen Ausführungen der Girlande 11 kann auch in der zuletzt
genannten Querrichtung die Girlande vor ihrem Einbringen
in die Kammer 9 über die betreffende Querschnittsabmessung
der Kammer hinausragen und erst nach ihrer Auseinanderziehung
eine derartige Deformation erfahren, daß
sich ihre Elemente auch an die Innenseiten der Kunststoffisolierstege
4, 5 anschmiegen.In the embodiment according to FIGS. 2 and 3, it is assumed
that the transverse dimension of the
Die Girlande 11 könnte im übrigen auch so in die Kammer 9
eingebracht werden, daß sich ihre Wellentäler 12 und
Wellenberge 13 nicht an die Innenseiten der Metallprofilteile
2, 3, sondern an die Innenseite der Kunststoffisolierstege
4, 5 anlegen. Auch auf diese Weise würden die
erwünschten, kleinen Kammerabschnitte entstehen, die einer
unerwünschten Konvektionsströmung im Innern der Kammer 9
entgegenwirken.The
Die Girlande 11 muß weiterhin nicht unbedingt wellenförmig
ausgebildet sein. Sie könnte auch beispielsweise zickzackförmig
oder in anderer Weise gefaltet sein, so lange nur
sichergestellt ist, daß sie beim Auseinanderziehen die gewünschte
Abdichtung an den Innenseiten der Kammer 9 herstellt
und so die einzelnen Kammerabschnitte 14 realisiert.The
Bei der in Fig. 4 und 5 dargestellten abgewandelten Ausführungsform
einer Girlande sind deren Abschnitte
zwischen den Wellentälern 12 und Wellenbergen 13 durch
flexible Elemente 15 miteinander verbunden, die eine Überdehnung
der Girlande verhindern. Vor dem Einbringen der
Girlande in die Kammer 9 ist die Girlande gemäß Fig. 5 in
der gleichen Weise wie in Fig. 3 zusammengeschoben, wobei
die flexiblen Elemente 15 schlaff sind.In the modified embodiment shown in FIGS. 4 and 5
the sections of a garland
between the
Die flexiblen Elemente 15, welche die Wellentäler 12 und
Wellenberge 13 der Girlande miteinander verbinden, können
als flexible Fäden, Bänder oder flächige Blatt- oder
Folienteile ausgebildet sein.The
Bei der Ausführungsform einer wärmedämmenden Girlande gemäß
Fig. 6 und 7 sind einzelne Elemente veränderlicher
Querdimension, beispielsweise flexible, zylindrische Gebilde
16 durch Verbindungsglieder 17 in Längsrichtung miteinander
verbunden. Die Verbindungsglieder können wiederum
als flexible Fäden, Bänder oder flächige Folien- oder
Blatt-Teile ausgebildet sein. Vor dem Einziehen der Girlande
in die Kammer 9 hat diese die schematisch in Fig. 7
dargestellte Gestalt, d.h. die in Fig. 6 kreisförmig verformten
Elemente 16 haben vor dem Einbringen in die Kammer
9 eine ovale Konfiguration, die sich nach dem Einziehen in
die in Fig. 6 dargestellte Kreisform verwandelt.According to the embodiment of a heat-insulating
Die Fig. 8 und 9 zeigen eine Doppelgirlande, bei der sich zwei wellenförmige Girlandenabschnitte gegenseitig durchdringen.8 and 9 show a double garland in which two wavy garland sections penetrate each other.
Bei der Ausführungsform gemäß Fig. 10 und 11 sind einzelne
quer zur Längsrichtung des Verbundprofils 1 und der Kammer
9 verlaufende, blattförmige Elemente 18 durch flexible,
zunächst schlaffe (Fig. 11) Verbindungsglieder 19 miteinander
verbunden. Die Elemente 18 können vor Einführung der
Girlande in die Kammer 9 über deren Querschnittsfläche
vorstehen. Beim Einziehen der Girlande in die Kammer 9
(vgl. den Pfeil Z) verbiegen sich die Ränder der Elemente
18 entsprechend und vermitteln ein dichtes Anliegen an den
betreffenden Innenseiten der Kammer 9. Die Elemente 18
können so ausgebildet sein, daß sich alle ihre vier Begrenzungsränder
in der in Fig. 10 dargestellten Weise beim
Anschmiegen an die benachbarten Kammerinnenwände entsprechend
umlegen.10 and 11 are individual
transverse to the longitudinal direction of the
Bei der Ausführungsform gemäß Fig. 12 und 13 ist das
eigentliche, wellenförmig ausgebildete Girlandenelement 21
mit flexiblen Elementen, z.B. Fäden 22, 23, insbesondere
durch Verflechtung verbunden. Das Girlandenelement 21
und/oder die einen weiteren Girlandenbestandteil bildenden
Fäden 22, 23 bestehen aus einem durch Wärme, Strahlen oder
chemisch expandierbaren oder aufrichtbaren Material, z.B.
Epoxid-, Phenol- oder Polyesterharz. Die Girlande wird zunächst
in der aus Fig. 13 ersichtlichen Art und Weise lose
in die Kammer 9 eingebracht. Danach erfolgt die Expansion
oder Aufrichtung, so daß schließlich der in Fig. 12 dargestellte
Zustand erreicht wird, in dem sich die Girlande
an die Innenseiten der Kammer 9 unter Ausbildung separater
Kammerabschnitte anschmiegt.In the embodiment according to FIGS. 12 and 13 that is
actual, wave-
Die Fig. 14 und 15 zeigen eine Girlande, die aus einem
zwei Schichten umfassenden, flexiblen Laminat besteht,
wobei jede Schicht aus einem zick-zackförmig gefalteten
Girlandenabschnitt 24 bzw. 25 besteht, die durch einen
flexiblen Mittelsteg 26 miteinander verbunden sind. Die
Fig. 13 zeigt die als Laminat ausgebildete Girlande gemäß
Fig. 12 vor ihrer Einbringung in die Kammer 9 des Verbundprofils
1.14 and 15 show a garland consisting of a
consists of two layers of flexible laminate,
each layer made from a zigzag folded
Garland
Es ist möglich, die Girlande auch als ein Laminat auszubilden, das aus mehr als drei Schichten besteht, wobei die Schichtung auch nach zwei Dimensionen hin verlaufen kann.It is possible to design the garland as a laminate, which consists of more than three layers, the Layering can also run in two dimensions.
Die Fig. 16 und 17 zeigen eine weitere bevorzugte Ausführungsform
einer wärmedämmenden Girlande. Diese Girlande
besteht entsprechend Fig. 17 vor ihrer Einbringung in die
Kammer 9 aus einem flexiblen unteren Band 27 und einem
flexiblen oberen Band 28, die durch Querstege 29 derart
miteinander verbunden sind, dap Kammerabschnitte mit
parallelogrammförmigem Querschnitt entstehen. Die Breite
der Querstege 29 entspricht dem Abstand zwischen den
Innenseiten der Kunststoffisolierstege 4, 5. In der aus
Fig. 17 ersichtlichen Gestalt kann die Girlande leicht in
die Kammer 9 eingezogen werden. Wird auf die oberen und
unteren Bänder 27, 28 ein Zug in den dargestellten Pfeilrichtungen
A bzw. B ausgeübt, so richten sich die Querstege
29 innerhalb der Kammer 9 in der aus Fig. 16
ersichtlichen Weise auf, so daß die Girlande sich nunmehr
auch an die Innenseiten der Metallprofilteile 2, 3 anschmiegt
und die Kammer 9 in einzelne, voneinander getrennte
Kammerabschnitte unterteilt ist. 16 and 17 show a further preferred embodiment
an insulating garland. This garland
exists according to Fig. 17 before their introduction into the
Die Fig. 16 und 17 dienen gleichzeitig der Veranschaulichung
einer weiteren Ausführungsform der Erfindung, die
sich im übrigen auch auf die zuvor beschriebenen Ausführungsformen
anwenden läßt. Wie in Fig. 17 durch die kleinen
Kreise 31 angedeutet, ist das die Girlande bildende
Material mit einem aufblähbaren Kunststoff imprägniert
oder beschichtet, also mit einem Kunststoff, der in bekannter
Weise ein Blähmittel, beispielsweise t-Buthylhydrazinchlorid
und Eisen-III-chlorid enthält. Hierfür geeignete
Kunststoffe sind z.B. ungesättigtes Polyesterharz,
Phenol- oder Melaminharz, Polyurethan, Polypropylen oder
Polyäthylen. Nach dem Einbringen der Girlande in die Kammer
9 des Verbundprofils (Fig. 16) wird das Blähmittel aktiviert,
so daß der Kunststoff expandiert und die einzelnen
Kammerabschnitte der Girlande vollständig ausfüllt.
Auf diese Weise ist auch eine Konvektionsströmung in den
einzelnen Kammerabschnitten verhindert. Gleichzeitig kann
so die Girlande in eine vollkommen starre Form übergeführt
werden, die auch zu einer Verfestigung des Verbundprofils
beitragen kann. Es ist möglich, auf diese oder eine ähnliche
Weise die Girlande zu einem starren Gebilde auszuhärten
und zu versteifen, das allein oder in Verbindung
mit den - gegebenenfalls entsprechend schwächer ausgebildeten
- Kunststoffisolierstegen 4, 5 in der Lage ist, die
statischen Anforderungen an das Verbundprofil (insbesondere
Schub- und Querzugsfestigkeit) zu erfüllen.16 and 17 serve for illustration at the same time
a further embodiment of the invention, the
otherwise also refer to the previously described embodiments
can be applied. As shown in Fig. 17 by the little ones

Phenolic or melamine resin, polyurethane, polypropylene or
Polyethylene. After inserting the garland into the
Die Fig. 18 zeigt im Gegensatz zu den Fig. 2, 4, 6, 8, 10,
12, 14 und 16 keine Längsschnitt-, sondern eine Querschnittsansicht
des Verbundprofils 1, wobei eine spezielle
Girlande gemäß Fig. 16, 17 Anwendung findet, deren Kammerabschnitte
vollständig mit aufgeschäumtem Kunststoff gefüllt
sind. Im Gegensatz zu der in Fig. 1 dargestellten
Ausführungsform des Verbundprofils 1 sind bei der Ausführungsform
gemäß Fig. 18 die beiden Profilteile 2, 3
nicht durch einzelne Kunststoffisolierstege 4, 5 miteinander
verbunden. Vielmehr sind in Fig. 18 diese Kunststoffisolierstege
4, 5 durch Querstege 32, 33, einstückig
miteinander verbunden, so daß insgesamt ein sogenannter
"Hohlkammersteg" gebildet ist. Im Falle der Fig. 18 ist
die Kammer 9 ganz von diesem Hohlkammersteg umschlossen
und die kunststoffgefüllte Girlande wird in die Kammer im
Inneren dieses Steges eingebracht.18 shows, in contrast to FIGS. 2, 4, 6, 8, 10,
12, 14 and 16 are not a longitudinal sectional view but a cross sectional view
of the
Es ist selbstverständlich auch möglich, in den Hohlkammersteg
gemäß Fig. 18 andere Girlanden, wie sie zuvor beschrieben
wurden, einzubringen.It is of course also possible to use the
Es ist auch möglich, durch Anwendung geeigneter, an sich
bekannter Klebstoffe, beispielsweise Kunststoffe, die Girlande
nach ihrem Einzug in die Kammer 9 mit wenigstens
einer Kammerinnenseite fest zu verbinden.It is also possible, by using more appropriate ones
known adhesives, such as plastics, the garland

Papier oder einem anderen Faserstoff aus natürlichen und/-oder
synthetischen Fasern, oder aus einem textilen Gewebe
oder Gewirk, oder aus Mischungen hiervon bestehen, wobei
insbesondere poröse Materialien Anwendung finden, wenn die
Girlande in der beschriebenen Weise mit klebefähigem oder
expandierbarem Kunststoff imprägniert werden soll.The described embodiments of
In der Praxis kann ein Verbundprofil gemäß Fig. 1 mit
einer wärmedämmenden Girlande 11 in seiner Kammer 9 vorteilhafterweise
wie folgt hergestellt werden: Man verbindet
die (aufgerichtete) Girlande 11 - beispielsweise durch
Verklebung - fest mit wenigstens einem der Metallprofilteile
2, 3 oder der Kunststoffisolierstege 4, 5. Hierauf
werden die Kunststoffisolierstege 4, 5 in die Metallprofilteile
2, 3 eingesetzt. Schließlich werden die schwalbenschwanzförmigen
Enden der Kunststoffisolierstege 4, 5
in die Nuten 7 der Metallprofilteile 2, 3 eingewalzt.In practice, a composite profile according to FIG
a heat-insulating
Die Verbindung der Kunststoffisolierstege 4, 5 mit der
Girlande 11 kann auch dadurch erfolgen, daß man diese
Stege 4, 5 an die Girlande 11 anspritzt. Falls eine Girlande
Anwendung findet, die ihrerseits durch Pultrusion
oder Extrusion hergestellt werden kann, ist eine solche
Anspritzung besonders günstig, wobei die Anspritzung in
Linie oder in einem nachfolgenden Arbeitsgang erfolgen
kann. Anstatt die Kunststoffisolierstege an die Girlande
anzuspritzen, können sie auch anextrudiert oder anpultrudiert
werden.The connection of the plastic insulating
Es ist schließlich auch möglich, statt nur einer einzigen
Girlande 11 mehrere solcher Girlanden gleichzeitig nebeneinander
in die Kammer 9 des Kunststoffprofils 1 einzubringen.After all, it is possible instead of just one
Bei bestimmten Ausführungsformen der Erfindung, beispielsweise
bei der Ausführungsform gemäß Fig. 16 und 17, ist es
vorteilhaft, die Girlande einseitig in der Kammer, beispielsweise
an der Innenseite des Metallprofilteils 2 zu
fixieren und dann durch Zug in Richtung des Pfeiles B
(Fig. 17) aufzurichten. In certain embodiments of the invention, for example
in the embodiment according to FIGS. 16 and 17, it is
advantageous, the garland unilaterally in the chamber, for example
on the inside of the
Das Aufstellen, Aufrichten oder Expandieren der vorgefertigten Girlande kann auch durch Erwärmung des Verbundprofils und damit der Girlande erfolgen, wobei beim Aufstell- oder Aufrichtvorgang der Girlande auch ein an sich bekannter "Memory-Effekt" des die Girlande bildenden Werkstoffes ausgenutzt werden kann.Setting up, erecting or expanding the prefabricated Garland can also be done by heating the composite profile and with it the garland. or erection process of the garland also a known one "Memory effect" of the material forming the garland can be exploited.
Die im Zusammenhang mit Fig. 12 und 13 beschriebene Aufweitung
der Girlande kann auch in der Weise erfolgen, daß
man sie kurz vor oder während der Montage mit einem Kunstharz
tränkt, wobei nach erfolgter Expansion die Aushärtung
auch ohne Wärmenachbehandlung, z.B. mittels geeigneter
Härtersysteme oder mittels Bestrahlen erfolgen kann. Auch
bei der Ausführungsform gemäß Fig. 12 und 13 kann ein
fester Verbund zwischen Girlande 11 und Verbundprofil 1
erreicht werden.The expansion described in connection with FIGS. 12 and 13
the garland can also be done in such a way that
one shortly before or during assembly with a synthetic resin
soaks, after curing the curing
