Description

Die Erfindung betrifft einen wärmeisolierenden Profilkörper, wie er im Oberbegriff des Patentanspruches 1 näher angegeben ist, sowie ein Verfahren zu seiner Herstellung.The invention relates to a heat-insulating profile body, as specified in the preamble of claim 1, and a method for its production.

Es sind wärmeisolierende Profilkörper bekannt, die aus zwei Profilschienen, beispielsweise Aluminiumprofilen, aufgebaut sind, wobei diese Profilschienen miteinander durch profilierte Isolierstege verbunden sind. Derartige Profilkörper werden insbesondere für Tür- oder Fensterrahmen verwendet, um eine Isolation zwischen der kalten Außenseite und der warmen Gebäudeinnenseite zu erzielen.Heat-insulating profile bodies are known which are constructed from two profile rails, for example aluminum profiles, these profile rails being connected to one another by profiled insulating webs. Such profile bodies are used in particular for door or window frames in order to achieve insulation between the cold outside and the warm inside of the building.

Ein derartiger wärmeisolierender Profilkörper ist beispielsweise aus der DE-AS 2 027 937 bekannt. Der dort beschriebene Profilkörper besteht aus zwei Profilschienen, die mit zwei Isolierstegen unter Bildung eines Hohlraumes zusammengesetzt sind. Der Hohlraum ist dabei zur Erhöhung der mechanischen Stabilität des Profilkörpers mit einer Schaumnasse ausgefüllt.Such a heat-insulating profile body is known for example from DE-AS 2 027 937. The profile body described there consists of two profile rails which are assembled with two insulating webs to form a cavity. The cavity is filled with a foam to increase the mechanical stability of the profile body.

Die Herstellung derartiger Profilkörper erfolgt gewöhnlich in der Weise, daß beispielsweise in hinterschnittene Nuten einer ersten, unteren Profilschiene die Isolierstege eingeschoben werden. Die Isolierstege und die Nuten sind dabei so dimensioniert, daß die Isolierstege in diesen Nuten Spiel haben. Sodann wird die zweite, obere Profilschiene mit entsprechenden Nuten auf die an der ersten, unteren Profilschiene vormontierten Isolierstege aufgeschoben. Die gegenseitige Fixierung der Profilschienen und der Isolierstege kann beispielsweise durch Verkleben oder, wie es in der DE-AS 2 027 937 beschrieben ist, durch Auffüllen des von den Profilschienen und den Isolierstegen gebildeten Hohlraumes mit einer Schaummasse erfolgen.Such profile bodies are usually produced in such a way that, for example, the insulating webs are inserted into undercut grooves in a first, lower profile rail. The insulating webs and the grooves are dimensioned so that the insulating webs have play in these grooves. Then the second, upper profile rail with corresponding grooves is pushed onto the insulating webs pre-assembled on the first, lower profile rail. The mutual fixing of the profile rails and the insulating webs can take place, for example, by gluing or, as described in DE-AS 2 027 937, by filling the cavity formed by the profile rails and the insulating webs with a foam compound.

Da bei derartigen Profilkörpern die Isolierstege in den -Nuten der Profilschienen Spiel haben, können die Isolierstege in diesen Nuten eine Kippbewegung quer zur Längsrichtung der Profilschienen ausführen. Dies kann dazu führen, daß die obere Profilschiene beim Aufschieben auf die Isolierstege einen Seitenversatz erleidet, so daß der von den Profilschienen und den Isolierstegen gebildete Hohlraum nicht einen rechtwinkligen, sondern einen rautenförmigen Querschnitt besitzt, so daß der hergestellte Profilkörper schief ist. Ein solcher Seitenversatz der oberen Profilschiene gegenüber der unteren Profilschiene ließe sich vermeiden, wenn diese Profilschienen beim Herstellungsverfahren von Lehren gehalten oder geführt werden. Durch derartige Maßnahmen wird das Herstellungsverfahren jedoch umständlich und aufwendiger.Since with such profile bodies the insulating webs have play in the grooves of the profile rails, the insulating webs can perform a tilting movement transversely to the longitudinal direction of the profile rails in these grooves. This can lead to the upper profile rail suffering a lateral offset when pushed onto the insulating webs, so that the cavity formed by the profile rails and the insulating webs does not have a rectangular but a diamond-shaped cross section, so that the profile body produced is crooked. Such a lateral offset of the upper rail relative to the lower rail could be avoided if these rails are held or guided by gauges during the manufacturing process. Such measures, however, make the manufacturing process cumbersome and complex.

Dementsprechend ist es Aufgabe der vorliegenden Erfindung, für einen wärmeisolierenden Profilkörper einen Aufbau anzugeben, durch den ein gegenseitiger, seitlicher Versatz der Profilschienen verhindert wird. Weiter soll von der Erfindung ein entsprechendes, geeignetes Herstellungsverfahren für einen derartigen Profilkörper angegeben werden.Accordingly, it is an object of the present invention to provide a structure for a heat-insulating profile body through which a mutual, lateral Offset of the rails is prevented. Furthermore, the invention is intended to provide a corresponding, suitable manufacturing method for such a profile body.

Diese Aufgabe wird bei einen wie im Oberbegriff des Patentanspruches 1 angegebenen wärmeisolierenden Profilkörper erfindungsgemäß nach der im kennzeichnenden Teil des Patentanspruches 1 angegebenen Weise gelöst.This object is achieved in a heat-insulating profile body as specified in the preamble of claim 1 according to the invention in the manner specified in the characterizing part of claim 1.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen wärmeisolierenden Profilkörpers sowie bevorzugte Verfahren zu seiner Herstellung sind in den Unteransprüchen angegeben.Advantageous embodiments of the heat-insulating profile body according to the invention and preferred methods for its production are specified in the subclaims.

Erfindungsgemäß sind an den Stützstegen der hinterschnittenen Nuten der ersten Profilschiene, in die beim Herstellungsverfahren die Isolierstege zuerst eingeschoben werden, einzelne, nach außen gerichtete Verformungen angebracht. Diese Verformungen sind derart ausgebildet, daß sie gegen die in den hinterschnittenen Nuten befindlichen Isolierstege anstoßen und diese dadurch wenigstens in der Umgebung dieser Verformungen nach außen drücken bzw. kippen. Das hat zur Folge, daß die Isolierstege wenigstens in diesen Bereichen nicht nach innen kippen können. Beim Aufschieben der oberen, zweiten Profilschiene werden die so nach außen gekippten Isolierstege wieder in die ursprünglich senkrechte Lage zurückgekippt bzw.-gebogen. Da die elastischen Kräfte dieser Isolierstege gegeneinander nach außen gerichtet sind, wird somit beim Aufschieben der zweiten, oberen Profilschiene ein Seitenversatz gegenüber der unteren Profilschiene verhindert. Dadurch, daß in Bereich dieser Verformungen ein seitlicher Versatz der beiden Profilschienen gegeneinander verhindert wird, wird er such wegen der Steifigkeit dieser Metallprofile ent-Profilkörpers verhindert. lang der Sesamten Länge des Profilkörpers verhindert.According to the invention, individual, outwardly directed deformations are attached to the support webs of the undercut grooves of the first profile rail, into which the insulating webs are first inserted during the manufacturing process. These deformations are designed such that they abut against the insulating webs located in the undercut grooves and thereby press or tilt them outwards at least in the vicinity of these deformations. As a result, the insulating webs cannot tilt inwards, at least in these areas. When the upper, second profile rail is pushed on, the insulating webs that are tilted outwards are tilted or bent back into the original vertical position. Since the elastic forces of these insulating webs are directed towards each other outwards, a lateral offset with respect to the lower profile rail is thus prevented when the second, upper profile rail is pushed on. Characterized in that a lateral displacement of the two rails against each other is prevented in the area of these deformations, he is prevented because of the rigidity of these metal profiles ent-profile body. long the sesame length of the profile body prevented.

Es wird nun der erfindungsgemäße wärneisolierende Profilkörper zusammen mit seinem Herstellungsverfahren beschrieben.The heat-insulating profile body according to the invention will now be described together with its production method.

Die Fig.1 zeigt eine erste, untere Profilschiene 2, die mit hinterschnittenen Nuten 6 versehen ist. Die hinterschnittenen Nuten werden jeweils von einem zur Innenseite hin liegenden Stützsteg 61 und einen Haltesteg 62 gebildet. In diese hinterschnittenen Nuten werden E-förmige Isolierstege 4 eingeschoben. Die Fig.2 zeigt einen Querschnitt durch diese untere Profilschiene 2 mit den eingeschobenen Isolierstegen 4. Wie anhand dieser Figur erkennbar ist, sind die Isolierstege 4 und die hinterschnittenen Nuten so dimensioniert, daß zwischen den Isolierstegen und den Nuteninnenflächen Toleranzspalte 63 vorhanden sind. Die Fig.3 zeigt nun, wie an den Stützstegen 61 einander gegenüberliegende Verformungen 8 erzeugt werden. Dazu wird zwischen die Stützstege 61 ein schraubenzieherartiges Werkzeug eingeführt. Die Unterkante 13 dieses Werkzeuges ist so dimensioniert, daß sie etwa um 2 mm länger ist als der Abstand der Stützstege 61. Bei Drehen des Werkzeuges 12 werden die Stützstege nach außen gedrückt, so daß sich Verformungen 8 (vergleiche Fig.4) ergeben. Die Drehung dieses Werkzeuges kamvon Hand oder auch mittels eines Elektroschraubers, Preßluftschraubers oder eines ähnlichen Werkzeuges erfolgen. Die Verformungen können alternativ auch dadurch erzeugt werden, daß das Werkzeug nicht gedreht, sondern nach außen gekippt bzw. gekantet wird. In Fig.4 ist das Ergebnis dieses Verfomuncsvorganges dargestellt. In Bereich der Verformungen 8 der Stützstege 61 werden die Isolierstege 4 gegen die Haltestege 62 gedrückt und nach außen gekippt. Dadurch wird gewährleistet; daß die Isolierstege 4 nicht nach innen kippen können.1 shows a first, lower profile rail 2, which is provided with undercut grooves 6. The undercut grooves are each formed by a support web 61 lying on the inside and a holding web 62. E-shaped insulating webs 4 are inserted into these undercut grooves. 2 shows a cross section through this lower profile rail 2 with the inserted insulating webs 4. As can be seen from this figure, the insulating webs 4 and the undercut grooves are dimensioned such that tolerance gaps 63 are present between the insulating webs and the inner surfaces of the grooves. 3 now shows how opposing deformations 8 are generated on the support webs 61. For this purpose, a screwdriver-like tool is inserted between the support webs 61. The lower edge 13 of this tool is dimensioned such that it is approximately 2 mm longer than the distance between the support webs 61. When the tool 12 is rotated, the support webs are pressed outwards, so that deformations 8 (see FIG. 4) result. This tool was turned by hand or by means of an electric screwdriver, pneumatic screwdriver or similar tool. The deformations can alternatively also be generated in that the tool is not turned, but tilted or folded outwards. The result of this deforming process is shown in FIG. In the region of the deformations 8 of the supporting webs 61, the insulating webs 4 are pressed against the holding webs 62 and tilted outwards. This ensures; that the insulating webs 4 cannot tilt inwards.

Die Fig.5 zeigt, wie die Isolierstege 4, die an der unteren Profilschiene 2 vormontiert sind, in entsprechende Nuten der zweiten, oberen Profilschiene 3 eingeschoben werden. Da der Abstand der Nuten der oberen Profilschiene 3 dem Abstand der Nuten der unteren Profilschiene 2 entspricht, werden beim Aufschieben die Isolierstege wieder in eine senkrechte Lage zurückgekippt bzw. zurückgebogen. Die dazu notwendigen Verformungskräfte greifen an den Nuten der oberen Profilschiene 3 an und heben einander auf. Da die elastischen Kräfte der Isolierstege nach außen gerichtet sind, kann ein seitlicher Versatz der oberen Profilschiene 3 gegenüber der unteren Profilschiene 2 im Bereich der Verformungen 8 nicht auftreten. Wenn somit am Anfang und am Ende der unteren Profilschiene 2 jeweils ein Paar von Verformungen 8 an den Stützstegen 61 angebracht ist, kann wegen der Steifigkeit der Profilschiene 2 bzw. 3 insgesamtkeine seitliche Verschiebung auftreten. Somit ist die obere Profilschiene 3 auf ihrer ganzen Länge gegenüber der unteren Profilschiene 2 ohne Seitenversatz.5 shows how the insulating webs 4, which are preassembled on the lower profile rail 2, are inserted into corresponding grooves in the second, upper profile rail 3. Since the distance between the grooves of the upper profile rail 3 corresponds to the distance between the grooves of the lower profile rail 2, the insulating webs are tilted back or bent back into a vertical position when pushed on. The necessary deformation forces act on the grooves of the upper profile rail 3 and cancel each other out. Since the elastic forces of the insulating webs are directed outwards, a lateral offset of the upper profile rail 3 with respect to the lower profile rail 2 in the region of the deformations 8 cannot occur. Thus, if a pair of deformations 8 is applied to the support webs 61 at the beginning and at the end of the lower profile rail 2, no lateral displacement can occur overall because of the rigidity of the profile rail 2 or 3. Thus, the upper rail 3 is along its entire length compared to the lower rail 2 without a lateral offset.

Grundsätzlich ist es ausreichend, wenn lediglich in der Nähe der beiden Enden der unteren Profilschiene 2 jeweils ein Paar von derartigen Verformungen 8 angebracht wird. Wenn sehr lange Profilkorper hergestellt werden sollen, kann es jedoch zweckmäßig sein, weitere Paare von Verformungen anzubringen. Es genügt jedoch, wenn diese Verformungen in Abständen von etwa 1 m angebracht werden. Da beim Aufschieben der oberen Profilschiene 3 im Bereich der Verformungen 8 Reibung zwischen den Nuten dieser oberen Profilschiene und den Isolierstegen auftritt, sollten zur Vermeidung großerer Reibungswiderstände diese Verformungen nicht zu dicht aufeinanderfolgen.Basically, it is sufficient if only a pair of such deformations 8 is applied only in the vicinity of the two ends of the lower profile rail 2. If very long profiled bodies are to be produced, however, it may be advisable to apply further pairs of deformations. However, it is sufficient if these deformations are applied at intervals of approximately 1 m. Since friction occurs between the grooves of this upper profile rail and the insulating webs when the upper profile rail 3 is pushed on in the area of the deformations 8, these deformations should not follow one another too closely in order to avoid greater frictional resistances.

Wie Fig. 5 weiter zeigt, wird zugleich mit dem Einschieben der Isolierstege 4 in die Nuten der oberen Profilschiene 3 der zwischen diesen Isolierstegen und den Profilschienen 2 bzw. 3 gebildete Hohlraum 5 mit einer Sohsummasse 9 gefüllt. Diese Schaunmasse 9 wird beispielsweise durch eine Spritzdüse 11 in den genannten Hohlraum eingedrückt. Die Schausinasse 9 expandiert vor ihrem Erstarren. Sie dringt dabei auch in die Toleranzspalte 63 ein, die sich zwischen den Isolierstegen 4 und den Innenwänden der Wuten 6 ausbilden. Sonit werden die Isolierstege in den Nuten durch die Schausnasse festgehalten. Ferner werden die Isolierstege durch den sich beim Expandieren der Schsunnasse ergebenden Druck auf Zug beansprucht, wodurch die Berührungsflächen zwischen den Isolierstegen 4 und den Haltestegen 62 der Nuten 6 aneinandergepreßt werden und einen Reibschluß bilden, der für eine hohe Steifigkeit des Profilkörpers sorgt. Die Schaummasse wirkt ferner auch verklebend und somit nach ihrem Erstarren auch arretierend auf das Gesamtgebilde.As Fig. 5 further shows, is also with the insertion the insulating webs 4 in the grooves of the upper profile rail 3, the cavity 5 formed between these insulating webs and the profile rails 2 and 3 filled with a Sohsummasse 9. This foam mass 9 is pressed into the cavity mentioned, for example, by a spray nozzle 11. The Schausinasse 9 expands before it solidifies. It also penetrates into the tolerance gaps 63 which form between the insulating webs 4 and the inner walls of the rims 6. The insulating webs are then held in place in the grooves by the showers. Furthermore, the insulating webs are stressed by the pressure resulting from the expansion of the Schsunnasse, whereby the contact surfaces between the insulating webs 4 and the holding webs 62 of the grooves 6 are pressed together and form a frictional engagement, which ensures a high rigidity of the profile body. The foam mass also has an adhesive effect and thus also locks onto the overall structure after it has solidified.

In der Fig.6 ist ein Schnitt durch einen entsprechenden, erfindungsgenäßen wärmeisolierenden Profilkörper dargestellt.6 shows a section through a corresponding heat-insulating profile body according to the invention.

Die Fig.7 und 8 zeigen ein weiteres Werkzeug, mit dem Verformungen an den Stützstegen 61 der ersten Profilschiene 2 vorgenommen werden können. Bei großen Abständen der Stützstege 61 kann das in Fig.3 dargestellte Werkzeug 12 nicht mehr für die Herstellung der Verformungen 8 eingesetzt werden, da aufgrund des großen Hebels für die Drehung des Werkzeuges ein sehr großer Kraftaufwand notwendig wird. In derartigen Fällen kann das in Fig.7 dargestellte Werkzaug zur Anwendung kommen. Es besteht im wesentlichen aus zwei beweglichen Stempeln 21, die durch eine Rückholfoder 22 zuweglichen Stempeln sammengehalten werden. Die Innenflächen 29 der Stempel 21 laufen konisch bzw. keilförmig zusammen. In den von diesen Innenflächen 29 gebildeten keilförmigen bzw. konischen Zwischenraum trifft eine entsprechend ausgestaltete Spreizvorrichtung 23, beispielsweise ein Keil. Dieser Keil ist an einem Anker 24 befestigt, der sich in einer Magnotspule 25 befindet. Bei Schließen eines Schalters 26 fließt aus einer Stromquelle 27 Strom durch die Magnetspule und drückt den Anker 24 in Pfeilrichtung nach unten, so daß die beweglichen Stempel 21 auseinandergetrieben werden und somit in den Stützstegen 61 die Verformungen 8 hervorrufen.FIGS. 7 and 8 show another tool with which deformations on the support webs 61 of the first profile rail 2 can be carried out. With large distances between the support webs 61, the tool 12 shown in FIG. 3 can no longer be used to produce the deformations 8, since the large lever for the rotation of the tool requires a very large amount of force. In such cases, the tool shown in Figure 7 can be used. It essentially consists of two movable stamps 21, which are held together by a return or 22 accessible stamps. The inner surfaces 29 of the stamp 21 converge conically or wedge-shaped. In the wedge-shaped or conical intermediate space formed by these inner surfaces 29, a correspondingly designed expansion device 23, for example a wedge, strikes. This wedge is fastened to an armature 24, which is located in a magnet coil 25. When a switch 26 is closed, current flows through the magnet coil from a current source 27 and presses the armature 24 downward in the direction of the arrow, so that the movable plungers 21 are driven apart and thus cause the deformations 8 in the support webs 61.

Die Fig.8 zeigt einen Querschnitt entlang der Linie VIII-VIII in Fig.7 durch das Verformungswerkzeug. Anhand der Fig.8 ist ersichtlich, daß die Stempel 21 in einem Gehäuse 28 geführt werden, so daß sie beim Auseinandertreiben senkrecht auf die Stütsstege 61 stoßen und diese verformen.8 shows a cross section along the line VIII-VIII in FIG. 7 through the shaping tool. It can be seen from FIG. 8 that the punches 21 are guided in a housing 28, so that when they drift apart they abut the support webs 61 and deform them.
