Description

Die Erfindung betrifft ein Verfahren zur Herstellung eines wärmeisolierenden Profilkörpers, wie er im Oberbegriff des Patentanspruches 1 näher angegeben ist.The invention relates to a method for producing a heat-insulating profile body, as specified in the preamble of claim 1.

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-B 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 Schaummasse ausgefüllt.Such a heat-insulating profile body is known for example from DE-B 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 compound 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-B 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-B 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 rather 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 make the manufacturing process cumbersome and complex.

Es ist zwar auch bekannt, bei bereits fertig vormontierten Profilteilen vom Hohlraum her die Stützstege gegen die Isolierstege zu pressen (FR-A-2 333 194), jedoch sind auch bei diesem Verfahren Haltelehren notwendig.It is also known to press the support webs against the insulating webs from the cavity in the case of already pre-assembled profile parts (FR-A-2 333 194), but this method also requires gauges.

Dementsprechend ist es Aufgabe der vorliegenden Erfindung, für einen wärmeisolierenden Profilkörper ein Verfahren anzugeben, durch das ein gegenseitiger, seitlicher Versatz der Profilschienen auf einfache Weise verhindert wird.Accordingly, it is an object of the present invention to provide a method for a heat-insulating profile body by which mutual, lateral displacement of the profile rails is prevented in a simple manner.

Diese Aufgabe wird bei einem 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 according to the invention in a heat-insulating profile body as specified in the preamble of patent claim 1 in the manner specified in the characterizing part of patent claim 1.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Verfahrens sowie ein Werkzeug zur Herstellung des Profilkörpers sind in den Unteransprüchen angegeben.Advantageous embodiments of the method according to the invention and a tool for producing the profile body are specified in the subclaims.

Erfindungsgemäß werden 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 und 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 im Bereich dieser Verformungen ein seitlicher Versatz der beiden Profilschienen gegeneinander verhindert wird, wird er auch wegen der Steifigkeit dieser Metallprofile entlang der gesamten Länge des Profilkörpers verhindert.According to the invention, individual, outwardly directed deformations are applied 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 and 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 slid on, the insulating webs that are tilted outwards are tilted back 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, it is also prevented because of the rigidity of these metal profiles along the entire length of the profile body.

Es wird nun der erfindungsgemäße wärmeisolierende 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 einem 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 kann von 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 Verformungsvorganges dargestellt. Im 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 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 outward, so that deformations 8 (see FIG. 4) result. This tool can be turned by hand or by means of an electric screwdriver, pneumatic screwdriver or a similar tool. The deformations can alternatively also be generated in that the tool is not turned, but tilted or folded outwards. 4 shows the result of this deformation process. 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 Verscheibung 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 attached to the support webs 61 at the beginning and at the end of the lower profile rail 2, overall lateral glazing cannot occur 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 est 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 Profilkörper 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 größerer 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 profile 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 Schaummasse 9 gefüllt. Diese Schaummasse 9 wird beispielsweise durch eine Spritzdüse 11 in den genannten Hohlraum eingedrückt. Die Schaummasse 9 expandiert vor ihrem Erstarren. Sie dringt dabei auch in die Toleranzspalte 63 ein, die sich zwischen den Isolierstegen 4 und den Innenwänden der Nuten 6 ausbilden. Somit werden die Isolierstege in den Nuten durch die Schaummasse festgehalten. Ferner werden die Isolierstege durch den sich beim Expandieren der Schaummasse 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, at the same time as the insulating webs 4 are inserted into the grooves in the upper profile rail 3, the cavity 5 formed between these insulating webs and the profile rails 2 and 3 is filled with a foam compound 9. This foam mass 9 is pressed, for example, by a spray nozzle 11 into the cavity mentioned. The foam mass 9 expands before it solidifies. It also penetrates into the tolerance gaps 63 that form between the insulating webs 4 and the inner walls of the grooves 6. The insulating strips are thus held in the grooves by the foam compound. Furthermore, the insulating webs are stressed by the pressure resulting from the expansion of the foam mass, as a result of which the contact surfaces between the insulating webs 4 and the holding webs 62 of the grooves 6 are pressed against one another 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, erfindungsgemäßen 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 Werkzeug zur Anwendung kommen. Es besteht im wesentlichen aus zwei beweglichen Stempeln 21, die durch eine Rückholfeder 22 zusammengehalten 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 Magnetspule 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.7 and 8 show a further 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 FIG. 7 can be used turn come. It essentially consists of two movable punches 21 which are held together by a return spring 22. The inner surfaces 29 of the punches 21 converge in a conical or wedge shape. In the wedge-shaped or conical intermediate space formed by these inner surfaces 29, a correspondingly designed expansion device 23, for example a wedge, hits. 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 Stützstege 61 stoßen und diese verformen.FIG. 8 shows a cross section along the line VIII-VIII in FIG. 7 through the deformation tool. 8 it can be seen 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.
