Description

Die Erfindung bezieht sich auf ein Verbundprofil aus durch Bolzen aus schweißbarem Material miteinander verbundenen Rohren mit zwischenliegender feuer- und temperaturwiderstandsfähiger Isolierschicht für Rahmen von Wandelementen, Türen und Fenstern, bei dem die die Isolierschicht durchsetzenden Bolzen an der der Isolierschicht zugekehrten Rohrwand festgelegt sind.The invention relates to a composite profile of pipes connected by bolts made of weldable material with an interposed fire and temperature-resistant insulating layer for frames of wall elements, doors and windows, in which the bolts penetrating the insulating layer are fixed to the pipe wall facing the insulating layer.

Es ist ein Verbundprofil dieser Art bekannt (DE-33 24 210 C2), bei dem die Rohre als Metallrohre ausgebildet und aus schweißbarem Material gefertigt sind. Diese Rohre werden durch Metallstege aus schweißbarem Material miteinander verbunden, die beiderends an der der Isolierschicht zugekehrten Rohrwand festgeschweißt sind.A composite profile of this type is known (DE-33 24 210 C2), in which the tubes are designed as metal tubes and are made of weldable material. These pipes are connected to each other by metal bars made of weldable material, which are welded to the pipe wall facing the insulating layer at both ends.

Die Metallrohre und auch die Metallstege werden mit einer Oberlfächenschutzschicht ausgestattet, da es aufgrund der Zulassungsbedingungen erforderlich ist, daß die Oberflächen der Metallrohre dauerhaft korrosionsgeschützt sind. Als Oberflächenschicht wird bei Stahlrohren eine Verzinkungsschicht vorgesehen. Durch die Verzinkung der Stahlrohroberfläche wird die Güte der Verschweißung zwischen den Metallrohren und den Metallstegen beeinträchtigt. Durch das Ausgasen bzw. Verflüssigen des Zinks ergeben sich Lunkereinschlüsse in der Verschweißung.The metal pipes and also the metal webs are equipped with a surface protection layer, since it is necessary due to the approval conditions that the surfaces of the metal pipes are permanently protected against corrosion. A galvanizing layer is provided as the surface layer for steel pipes. The galvanizing of the steel pipe surface affects the quality of the weld between the metal pipes and the metal webs. Outgassing or liquefying the zinc creates blowholes in the weld.

Da die Metallstege mit den Metallrohren nacheinander verschweißt werden, können die für die Verschweißung erforderlichen Impulsströme über Nebenschlüsse durch die bereits verschweißten Metallstege an Wirkung verlieren.Since the metal webs are welded to the metal tubes one after the other, the impulse currents required for the welding can lose their effectiveness through shunts through the already welded metal webs.

Es kommt hinzu, daß bei der Herstellung des bekannten Verbundprofils ausschließlich Metallrohre aus schweißbarem Material verwendet werden können.In addition, only metal pipes made of weldable material can be used in the production of the known composite profile.

Der Erfindung liegt die Aufgabe zugrunde, ein Verbundprofil der eingangs genannten Art so zu gestalten, daß die Güte der Verschweißung im Bolzenbereich verbessert wird.The invention has for its object to design a composite profile of the type mentioned so that the quality of the weld in the bolt area is improved.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß jeder Bolzen zweiteilig ausgebildet, die Teilungsfläche winklig zur Bolzenlängsachse verläuft, frei von einer Oberflächenschutzschicht ist und die Bolzenteile nach dem Aufsetzen der Isolierschicht miteinander verschweißt werden.This object is achieved in that each bolt is formed in two parts, the dividing surface is at an angle to the longitudinal axis of the bolt, is free of a surface protective layer and the bolt parts are welded together after the insulating layer has been put on.

Beim erfindungsgemäßen Verbundprofil werden zwei blanke Stirnflächen der Bolzenteile- miteinander verschweißt.Der Bolzenmantel kann mit einer Oberflächenschutzschicht versehen sein. Bei Bolzen mit einem relativ großen Durchmesser kann die Oberflächenschutzschicht entfallen.In the composite profile according to the invention, two bare end faces of the bolt parts are welded together. The bolt shell can be provided with a surface protective layer. The surface protective layer can be omitted for bolts with a relatively large diameter.

Damit im Bereich der Teilungsflächen ein Toleranzausgleich zwischen den Metallrohren erfolgen kann, mit denen die Bolzenteile verbunden sind, weist die Isolierschicht eine von einer seitlichen Begrenzungsfläche ausgehende bis zur Bolzenteilungsfläche sich erstreckende Aussparung auf. Hierdurch wird eine Verschiebung der Bolzenteile im Bereich der Teilungsflächen möglich, ohne daß eine Behinderung durch die Isolierschicht auftritt.So that a tolerance compensation between the metal pipes to which the bolt parts are connected can take place in the area of the dividing surfaces, the insulating layer has a recess extending from a lateral boundary surface to the bolt dividing surface. This makes it possible to move the bolt parts in the area of the dividing surfaces without being impeded by the insulating layer.

Diese Aussparung kann zylindrisch oder als Senkbohrung ausgebildet sein.This recess can be cylindrical or countersunk.

Die Bolzenteile können mit den Rohren des Verbundprofils verschraubt werden.The bolt parts can be screwed to the pipes of the composite profile.

In diesem Fall ist es nicht erforderlich, daß die Rohre aus einem schweißbaren Material gefertigt werden. Die Rohren können somit aus einem beliebigen Material, z.B. aus Edelstahl, aus Aluminium, aus Kunststoff oder aus Verbundwerkstoffen hergestellt sein.In this case, it is not necessary for the pipes to be made from a weldable material. The tubes can thus be made of any material, e.g. be made of stainless steel, aluminum, plastic or composite materials.

Weitere Merkmale der Erfindung ergeben sich aus den Unteransprüchen.Further features of the invention emerge from the subclaims.

Cross-section of composite profiles of different designs.

In der Fig. 1 ist eine zweiflügelige Schutztür gegen Feuer und Rauch aufgezeigt, deren Flügel 1 und 2 mit einer Isolierverglasung 3 ausgestattet sind.In Fig. 1, a two-leaf protective door against fire and smoke is shown, the wings 1 and 2 are equipped with double glazing 3.

Aus der Fig. 2 ergibt sich der Aufbau der Flügelrahmen im Bereich des in der Fig. 1 angegebenen Schnittes II-II.The structure of the casement in the area of the section II-II shown in FIG. 1 results from FIG. 2.

Die Flügelrahmen werden durch aus Stahl gefertigte Hohlprofile 4,5 gebildet, zwischen denen eine feuer- und temperaturwiderstandsfähige Isolierschicht 6 angeordnet ist. Die Hohlprofile 4,5 werden durch Bolzen 7 miteinander verbunden, die sich durch Bohrungen in der Isolierschicht 6 erstrecken und endseitig an den Wandungen der Hohlprofile 4,5 festgelegt sind, die der Isolierschicht 6 benachbart liegen.The casement frames are formed by hollow sections 4. 5 made of steel, between which a fire and temperature resistant insulating layer 6 is arranged. The hollow profiles 4, 5 are connected to one another by bolts 7 which extend through bores in the insulating layer 6 and are fixed at the ends to the walls of the hollow profiles 4, 5 which are adjacent to the insulating layer 6.

Die aus Stahlblechen gefertigten Hohlprofile 4,5 werden nach außen durch aus Aluminium gefertigte Profilschienen 8,9 abgedeckt.The hollow profiles 4.5 made of steel sheets are covered on the outside by profile rails 8.9 made of aluminum.

Bei der Ausführung nach der Fig. 3 weist das Verbundprofil 10 rechteckige Rohre 12 und 13 auf, zwischen denen eine feuer- und temperaturwiderstandsfähige Isolierschicht 14 angeordnet ist. Diese Isolierschicht wird von Bolzen 15 aus schweißbarem Material durchsetzt. Jeder Bolzen 15 ist zweiteilig ausgebildet und besteht aus den Bolzenteilen 16 und 17, die an der dem Rohr 12 bzw. dem Rohr 13 zugewandten Seite einen Gewindezapfen 18 bzw. 19 aufweisen. Diese Gewindezapfen sind in eine Gewindebohrung der Rohrwand 20 bzw. 21 eingeschraubt, die der Isolierschicht 14 benachbart liegt.In the embodiment according to FIG. 3, the composite profile 10 has rectangular tubes 12 and 13, between which a fire and temperature-resistant insulating layer 14 is arranged. This insulating layer is made of bolts 15 made of weldable material. Each bolt 15 is formed in two parts and consists of the bolt parts 16 and 17, which have a threaded pin 18 and 19 on the side facing the tube 12 and tube 13, respectively. These threaded pins are screwed into a threaded bore in the tube wall 20 or 21, which lies adjacent to the insulating layer 14.

In der Fig. 1 weisen die Bolzenteile 16,17 eine unterschiedliche Länge auf. Die Teilungsfläche 22 zwischen den Bolzenteilen 16 und 17 verläuft rechtwinklig zur Bolzenlängsachse 23. Der Verlauf der Teilungsfläche 22 zur Bolzenlängsachse 23 kann auch unter einem Winkel erfolgen, der vom rechten Winkel abweicht.In Fig. 1, the bolt parts 16, 17 have a different length. The dividing surface 22 between the bolt parts 16 and 17 extends at right angles to the longitudinal axis 23 of the bolt. The course of the dividing surface 22 to the longitudinal axis 23 of the bolt can also take place at an angle which deviates from the right angle.

In der Teilungsfläche weisen die Bolzenteile 16 und 17 keine Oberflächenschutzschichten auf. Die in der Teilungsfläche zusammenstoßenden Stirnflächen der Bolzenteile sind als blanke Flächen ausgebildet, so daß bei einer Verschweißung der Bolzenteile 16 und 17 sich eine hohe Schweißgüte ergibt. Die Verschweißung erfolgt durch ein Abbrennstumpfschweißverfahren oder durch ein Impulsschweißverfahren.The bolt parts 16 and 17 have no surface protective layers in the division area. The end faces of the bolt parts that collide in the dividing surface are formed as bare surfaces, so that when the bolt parts 16 and 17 are welded, a high welding quality results. The welding is carried out by a flash butt welding process or by a pulse welding process.

Bei der Herstellung des Verbundprofils nach der Fig. 3 werden zunächst die Bolzenteile 16 und 17 mit den Wandungen 20 und 21 der Rohre 12 und 13 verschraubt. Auf die Bolzenteile 17, die wie die Bolzenteile 16 über die Länge der Rohre 12 und 13 verteilt angeordnet sind, wird die Isolierschicht 4 gestülpt. Dann werden die Bolzenteile 16 und 17 miteinander verschweißt.In the manufacture of the composite profile according to FIG. 3, the bolt parts 16 and 17 are first screwed to the walls 20 and 21 of the tubes 12 and 13. The insulating layer 4 is placed over the bolt parts 17, which are arranged like the bolt parts 16 over the length of the tubes 12 and 13. Then the bolt parts 16 and 17 are welded together.

Die Bolzenteile 16 und 17 werden bezüglich ihrer Länge zwischen den Rohren 12 und 13 so bemessen, daß sie innerhalb des durch die Isolierschicht 14 gebildeten Abstandes zur Anlage kommen und in diesem Anlagebereich über eine Schweißzugabe verfügen, die beim angewendeten Abbrennstumpfschweißen bzw. Impulsschweißen für eine saubere vollflächige Verbindung der Bolzenteile sorgt und die Isolierschicht 14 weitgehendst spielfrei zwischen den Rohren 12 und 13 einspannt. Die Stirnflächen der Bolzenteile 16 und 17, die miteinander verschweißt werden, können mit Ringschneiden oder Nocken für ein gezieltes Schweißen zusätzlich ausgestattet sein.The bolt parts 16 and 17 are dimensioned with respect to their length between the tubes 12 and 13 so that they come to rest within the distance formed by the insulating layer 14 and have a welding allowance in this contact area, which when used flash butt welding or pulse welding for a clean full-surface connection of the bolt parts ensures and the insulating layer 14 clamped largely free of play between the tubes 12 and 13. The end faces of the bolt parts 16 and 17, which are welded to one another, can additionally be equipped with ring cutting edges or cams for targeted welding.

Damit im Bereich der Teilungsfläche 22 ein Toleranzausgleich zwischen den zu verbindenden Bauteilen stattfinden kann, ist die Isolierschicht 14 mit Aussparungen 24 versehen, die sich bis zu der Teilungsfläche 22 oder ein wenig darüber hinaus erstrecken.So that a tolerance compensation between the components to be connected can take place in the area of the dividing surface 22, the insulating layer 14 is provided with recesses 24 which extend up to the dividing surface 22 or a little beyond.

Diese Aussparungen sind im Ausführungsbeispiel nach den Fig. 3 und 5 als zylindrische Aussparungen 24 ausgebildet. Bei dem Ausführungsbeispiel nach der Fig. 4 weisen die Aussparungen die Form ein Senkbohrung 15 auf.In the exemplary embodiment according to FIGS. 3 and 5, these cutouts are designed as cylindrical cutouts 24. In the exemplary embodiment according to FIG. 4, the cutouts have the shape of a counterbore 15.

Zwischen den Bolzenteilen 16 und 17 können erhebliche Toleranzen ausgeglichen werden. Lediglich die Aufnahmebohrung in der Isolierschicht 14 für den jeweiligen Bolzen und die Positionierung des Bolzenteiles 17 gegenüber dem Rohr 13 müssen positionsmäßig aufeinander abgestimmt sein, wobei der Bohrungsdurchmesser und der Durchmesser des Bolzenteils 17 zum Toleranzausgleich herangezogen werden können.Considerable tolerances can be compensated for between the bolt parts 16 and 17. Only the receiving bore in the insulating layer 14 for the respective bolt and the positioning of the bolt part 17 with respect to the tube 13 must be coordinated with one another in terms of position, the bore diameter and the diameter of the bolt part 17 being able to be used for tolerance compensation.

Das Bolzenteil 16, das auf dem Rohr 12 positioniert und fixiert ist, weist eine solche Bauhöhe auf, daß es sich innerhalb der Aussparung 24 der Isolierschicht 14 befindet und so in der Lage ist, größere Fluchtungsfehler mit dem Bolzenteil 17 problemlos auszugleichen.The bolt part 16, which is positioned and fixed on the tube 12, has such a height that it is located within the recess 24 of the insulating layer 14 and is thus able to compensate for larger misalignments with the bolt part 17 without problems.

Bei dem Verbundprofil 26 nach der Fig. 4 sind die Bolzenteile 27 mit der Innenwand 28 des Rohres 29 verschraubt und zwar über einen Gewindezapfen 30, der in Gewindebohrungen der Innenwand 28 eingeschraubt wird oder der mit einem Schneidgewinde ausgerüstet ist.In the composite profile 26 according to FIG. 4, the bolt parts 27 are screwed to the inner wall 28 of the tube 29, specifically via a threaded pin 30 which is screwed into threaded holes in the inner wall 28 or which is equipped with a cutting thread.

Das Bolzenteil 31 ist mit dem Rohr 32 verschweißt. Die Teilungsfläche 22 zwischen den Bolzenteilen 27 und 31, an der die Verschweißung der Bolzenteile erfolgt, liegt ebenfalls wie bei der Ausführungsform nach der Fig. 3 benachbart dem Rohr 29.The bolt part 31 is welded to the tube 32. The dividing surface 22 between the bolt parts 27 and 31, on which the bolt parts are welded, is also, as in the embodiment according to FIG. 3, adjacent to the tube 29.

Bei der Ausführungsform nach der Fig. 5 werden die Bolzen 33 durch Bolzenteile 34,35 gebildet, die mit der zugeordneten Innenwand 36,37 der Rohre 38,39 verschweißt sind. Die Bolzenteile 34,35 werden in der Teilungsfläche 22 miteinander verschweißt und durchsetzen wie in den übrigen Verbundprofilen nach den Fig. 2,3 und 4 eine Isolierschicht 40.In the embodiment according to FIG. 5, the bolts 33 are formed by bolt parts 34, 35 which are welded to the associated inner wall 36, 37 of the tubes 38, 39. The bolt parts 34, 35 are welded to one another in the dividing surface 22 and penetrate as in the other composite profiles 2, 3 and 4, an insulating layer 40.

Bei dem Ausführungsbeispiel nach der Fig. 6 weisen die Bolzenteile 41,42 kegelförmige Ansätze 43,44 auf, die in kegelförmige Bohrungen der Innenwände 45 und 46 eingreifen oder sich durch diese Bohrungen bis in den Innenraum der Rohre 47,48 erstrecken. Sowohl die Oberfläche der kegelförmigen Ansätze 43,44 als auch die Bohrungsflächen in den Innenwänden 45,46 sind frei von einer Oberflächenschutzschicht (Zink), so daß eine Verschweißung mit hoher Qualitätsgüte zwischen den Ansätzen 43,44 und den Innenwandungen 45,46 vorgenommen werden kann.In the exemplary embodiment according to FIG. 6, the bolt parts 41, 42 have conical projections 43, 44 which engage in conical bores in the inner walls 45 and 46 or extend through these bores into the interior of the tubes 47, 48. Both the surface of the conical projections 43, 44 and the bore surfaces in the inner walls 45, 46 are free of a surface protective layer (zinc), so that welding with high quality can be carried out between the projections 43, 44 and the inner walls 45, 46 .

In der Fig. 7 wird eine Schweißvorrichtung aufgezeigt, die in die Hohlkammer der Rohre 12 und 13 eingeführt wird, mit der die Bolzenteile 16,17 im Bereich der Teilungsfläche 22 verschweißt werden.FIG. 7 shows a welding device which is inserted into the hollow chamber of the tubes 12 and 13, with which the bolt parts 16, 17 are welded in the region of the dividing surface 22.

Die Befestigungsmittel der Bolzenteile 16,17, die als Gewindezapfen 18,19 ausgebildet sind, erstrecken sich in die Hohlkammern der Rohre 12,13. Bei dieser Konzeption kann ein Schweißverfahren angewendet werden, bei dem die Kontaktierung nicht über die Metallrohre 12,13 von der Außenseite her erfolgt, sondern direkt an den Bolzenteilen 16,17 vorgenommen wird. Bei diesem Verfahren wird eine bzw. es werden beide Elektroden in die Hohlkammer eingeführt und an dem jeweiligen Befestigungsmittel durch entsprechende Taktvorschübe im Rohr fixiert. Nach erfolgtem Schweißvorgang wird das Rohr weitergetaktet und der Schweißvorgang erfolgt am nächsten Befestigungsmittel des Bolzenteils in gleicher Weise.The fastening means of the bolt parts 16, 17, which are designed as threaded pins 18, 19, extend into the hollow chambers of the tubes 12, 13. With this conception, a welding process can be used in which the contact is not made via the metal pipes 12, 13 from the outside, but is made directly on the bolt parts 16, 17. In this method, one or both electrodes are inserted into the hollow chamber and fixed to the respective fastening means by means of corresponding clock feeds in the tube. After the welding process has been carried out, the pipe is cycled further and the welding process is carried out in the same way on the next fastening means of the bolt part.

Die Kontakteinheit 49 bzw. 50 bzw. die Kontakteinheiten 49 und 50 werden in die Hohlkammern der Rohre 12 und 13 eingeschoben und bestehen jeweils aus dem elektrisch leitenden Kontakt 51 bzw. 52 und einer Spanneinheit 53 bzw. 54, die gleichzeitig die Isolierung der Elektroden zu den Rohren 12, 13 vornehmen.The contact units 49 and 50 or the contact units 49 and 50 are inserted into the hollow chambers of the tubes 12 and 13 and each consist of the electrically conductive contact 51 and 52 and a clamping unit 53 and 54, which simultaneously isolate the electrodes make the tubes 12, 13.

Sobald die Kontakte ihre Schweißposition zum Bolzen erreicht haben, wird die komplette Einheit 49 bzw. 50 oder 49 und 50 in der Hohlkammer festgeklemmt. Nach erfolgtem Schweißimpuls wird die Einheit gelöst und das Verbundprofil zum nächsten Bolzen weitergetaktet.As soon as the contacts have reached their welding position to the stud, the complete unit 49 or 50 or 49 and 50 is clamped in the hollow chamber. After the welding pulse, the unit is released and the composite profile clocked to the next bolt.

Durch diese Anordnung ist ein Nebenschluß über bereits verbundene Bolzen annähernd ausgeschlossen, so daß für jeden einzelnen Bolzen ein Maximum an Schweißenergie für eine ordnungsgemäße Verschweißung zur Verfügung steht.By this arrangement, a shunt over already connected bolts is almost impossible, so that a maximum of welding energy is available for proper welding for each individual bolt.

Sofern die Rohre 12,13 aus leitendem Material bestehen, kann natürlich auch die Verschweißung von der Außenseite her vorgenommen werden.If the tubes 12, 13 consist of conductive material, the welding can of course also be carried out from the outside.

Bei dem Ausführungsbeispiel nach der Fig. 8 ist ein Verbundprofil aufgezeigt, bei dem die Bolzenteile 55,56 über ein Einziehniet (Popnietung) 57 an der zugeordneten Innenwand 58 bzw. 59 des Rohres 60 bzw. 61 festgelegt werden.
