Eckverbinder zum Verbinden zweier auf Gehrung geschnittener HohlkämmerpröfileCorner connector for connecting two mitred hollow chamber profiles
Die Erfindung betrifft einen EckVerbin.der zum Verbinden zweier auf Gehrung geschnittener Höhlkammerprofile gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a corner connector for connecting two mitred hollow chamber profiles according to the preamble of claim 1.
Eckverbihder dienen zur Verbindung zweier auf Gehrung geschnittener Hohlkammerprofile> wobei die Eckverbinder (-halbstücke) in die Hohlkammerprofile eingeschoben, durch kraft- oder formschlüssige Verbindung ah den Höhlkammerprofilen fixiert und untereinander durch Schrauben 'öder Verschweißen verbunden werden»Corner connectors are used to connect two mitred hollow chamber profiles, whereby the corner connectors (half pieces) are inserted into the hollow chamber profiles, fixed to the hollow chamber profiles by means of a force-fitting or form-fitting connection and connected to one another by means of screws or welding.
Derartige Eckverbinder zum Verbinden von Hohlkammerprofilen sind aus der DE-OS 17 75 385 j DE-OS 21 30 639, DE-OS 21 34 520, DE-OS 21 29 858 und DE-OS 33 20 624 A1 be-^ kannt. Ein gattungsgemäßer Eckverbinder ist weiterhin aus der DE-OS 23 36 839 bekanntgeworden.Such corner connectors for connecting hollow chamber profiles are known from DE-OS 17 75 385 j DE-OS 21 30 639, DE-OS 21 34 520, DE-OS 21 29 858 and DE-OS 33 20 624 A1. A corner connector of this type is also known from DE-OS 23 36 839.
Die zu verbindenden Höihlkämmerprofile können als Metalloder Kunststoffprofile ausgebildet sein, insbesondere aber als durch eingeschobene Metallhohlprofile versteifte Kunststoffprofile.The hollow chamber profiles to be connected can be designed as metal or plastic profiles, but in particular as plastic profiles stiffened by inserted hollow metal profiles.

Die Bekannten Eckverbinder haben den Nachteil, daß sie
entweder Unzureichend in dem Höhlkämm&fßröfii fixiert
Werden können, so daß eine unzureichende Festigkeit und
Steifigkeit der Eckverbindung zu verzeichnen ist, öder
daß die Eckverbinder durch die äußere Kontur der Höhlkammerprofile
durchdringende Befestigungselemefite
fixiert Werden müssen. Letzteres ist insbesondere beim
Einsatz VDH Eck Verbindern zum verbinden von Fettster- oder
Tüfprofilen Von Nachteil*The known corner connectors have the disadvantage that they
either insufficiently fixed in the hollow ridge
Can be so that insufficient strength and rigidity of the corner connection is recorded, or
that the corner connectors have fastening elements penetrating the outer contour of the hollow chamber profiles
Must be fixed. The latter is particularly important for
Use of VDH corner connectors to connect Fettster or Tüf profiles Disadvantage*
Aufgabe der Erfindung ist es deshalb, einen gattungsgemäßen EckVefbinder so fortzubilden, daß er eine Eckverbindung
hoher Steifigkeit und Festigkeit ermöglicht,
ohne daß Befestigungselemente eingesetzt Werden müssen, die die äußere Kontur der Hohlkammefprofile durchstoßen, i
die also Von außen sichtbar sind.The object of the invention is therefore to develop a generic corner connector in such a way that it enables a corner connection of high rigidity and strength,
without the need to use fastening elements that penetrate the outer contour of the hollow-comb profiles and are therefore visible from the outside.
Die Erfindung löst diese Aufgabe durch einen Eckverbinder
gemäß den. Anspruch 1, bevorzugt in Verbindung mit den
Merkmalen der Weiteren Ansprüche.The invention solves this problem by a corner connector according to claim 1, preferably in conjunction with the
Features of the further claims.
Zum Verbinden zweier auf Gehrung geschnittener Hohlkammerprofile wird je ein Eckverbinder gemäß der Erfindung in die bzw· eine der Hohlkammer(n) der Hohlkammerprofile geschoben. Zweckmäßig erfolgt das Einschieben der-^ art, daß die als Schweißfläche ausgebildete Gehrungsfläche der Eckverbinder etwa bündig mit der Gehrungsfläche des Hohlkammerprofils abschließt, oder daß die Schweißfläche der Eckverbirider um einige mm das Hohlkaittmerprofil überragt.To connect two mitred hollow chamber profiles, a corner connector according to the invention is pushed into each of the hollow chambers of the hollow chamber profiles. The insertion is preferably carried out in such a way that the miter surface of the corner connector, which is designed as a welding surface, is approximately flush with the miter surface of the hollow chamber profile, or that the welding surface of the corner connector projects a few mm beyond the hollow chamber profile.
Zum Fixieren der Eckverbinder in den Hohlkammerprofilen weist der Eckverbinder an dem der Gehrungsfläche entgegengesetzten Ende zwei kreuzförmig zueinander angeordnete^ te Spreizschlitze sowie eine, sich etwa axial über dieTo fix the corner connectors in the hollow chamber profiles, the corner connector has two expansion slots arranged in a cross shape at the end opposite the mitre surface, as well as one extending approximately axially over the
Länge des Eckverbinders erstreckende i zylindrische öder kegeiförmige Bohrung auf. Durch' Spreizen der Spreizschlitze Wird eine kräftschlüssige Verbindung zwischen dem Eckverbinder und dem Hohlkammerprofü erreicht. Das Spreizen erfolgt beispielsweise durch einen an sich bekannten Spreizdübel, der in die zylindrische oder kegelförmige Bohrung eingebracht wurde. Der Spreizdübel wird dabei durch Anziehen einer in den Spreizdübel eingeschraubten Schraube o. dgl. gespreizt. Ein axiales Verschieben des Spreizdübels wird dabei durch eine entsprechend aufgerauhte oder mit Widerhaken versehene Außenkontur des Spreizdübeis verhindert. Um die notwendige axiale Zugkraft auf den Spreizdübel ausüben zu können, weist die zylindrische oder kegelförmige Bohrung im Bereich der Gehrungsfläche des Eckverbinders einen entsprechenden Absatz auf. Es ist dabei wesentlich, daß der Schraubenkopf in diesen erweiterten Teil der Bohrung vollständig Versenkbar ist, damit ein Verschweißen der Eckverbinder möglich ist.The corner connector has a cylindrical or conical bore extending the length of the corner connector. By expanding the expansion slots, a force-locking connection is achieved between the corner connector and the hollow chamber profile. The expansion is achieved, for example, by means of a known expansion dowel which has been inserted into the cylindrical or conical bore. The expansion dowel is expanded by tightening a screw or similar screwed into the expansion dowel. Axial displacement of the expansion dowel is prevented by an appropriately roughened or barbed outer contour of the expansion dowel. In order to be able to exert the necessary axial tensile force on the expansion dowel, the cylindrical or conical bore has a corresponding shoulder in the area of the miter surface of the corner connector. It is essential that the screw head can be completely countersunk into this expanded part of the bore so that the corner connectors can be welded.

Bevorzugt wird zum Spreizen der Eckverbinder ein kegelstumpf förmiger, in Achsrichtung ein Innengewinde aufweisender Spreizkeil verwendet, dessen größter Durchmesser größer und dessen kleinster Durchmesser kleiner ist als der Durchmesser der Bohrung des Eckverbinders am der Gehrungsfläche entgegengesetzten Ende. Bevorzugt weist der 5preizkeil eine oder mehrere Nasen auf, die in die Spreizschlitze des Eckverbinders eingreifen und so ein Dreheri des Spreizkeils in der Bohrung des Eck-Verbinders verhindern.Preferably, a truncated cone-shaped expansion wedge with an internal thread in the axial direction is used to expand the corner connectors, the largest diameter of which is larger and the smallest diameter of which is smaller than the diameter of the hole in the corner connector at the end opposite the miter surface. Preferably, the expansion wedge has one or more lugs which engage in the expansion slots of the corner connector and thus prevent the expansion wedge from turning in the hole in the corner connector.
Eine in daö Innengewinde des Spreizkeils eingeschraubte Schraube, deren Kopf in dem Eckverbinder versenkt angeordnet ist, bewirkt beim Anziehen der Schraube ein axiales Verschieben des Spreizkeils in Richtung auf dieA screw screwed into the internal thread of the expansion wedge, the head of which is countersunk in the corner connector, causes an axial displacement of the expansion wedge in the direction of the
GehTUrigsflache des EckVerbinders. Damit wird die SpreizUrig des EckVerbinders am der GehrUhgsfiäche ent= gegengesetzten £ftüe des Eckvefbinders bewirkt*The corner connector's mitre surface. This causes the corner connector to spread at the side opposite the corner connector's mitre surface *
'Die Äußenkontur des EckVerbinders muß, um eine kraftschiüssige Verbindung des EckverbifideSs mit dem Hohlkammerprofil zu ermöglichen» eine der Innenkontur des Hohlkammerprofils angepaßte Form aufweisen. Zweckmäßig weist der in das Höhlkammerprofil eingeschobene Eckverbinder dabei ein Spiel Von etwa 0,1 bis 1,5 mm auf."The outer contour of the corner connector must have a shape that matches the inner contour of the hollow chamber profile in order to enable a force-fitting connection between the corner connector and the hollow chamber profile." It is advisable for the corner connector inserted into the hollow chamber profile to have a clearance of around 0.1 to 1.5 mm.
Soweit der Eckverbirider einen rechteckigen oder trapezförmigen Querschnitt aufweist, ist nach einer bevorzugten Weiterbildung der Erfindung vorgesehen, daß an drei j der vier Außenflachen des EckVerbindärs, ausgehend von \ der Gehrungsflache, in Achsrichtung verläufende, stegförmige Gleitnocken angebracht sind. Auf jeder dieser ■ drei Außenflächen ist dabei wenigstens ein, bevorzugt zv/ei oder mehr Gleitnocken angebracht. Die Gleitnocken bewirken, daß der Eckverbinder beim Einschieben in die Hohlkammer des Hohlkammerprofils im Bereich der Gehrungs fläche durch Preßpässung mit dem Hohlkammerpfofil rutschsicher Verbunden ist. Die nicht mit Gleitnocken versehene vierte Außenfläche liegt dabei plan auf einer Innenwand der Hohlkammer des Hohlkammerprofils auf, so daß die Übertragung auch höherer Kräfte möglich ist.If the corner connector has a rectangular or trapezoidal cross-section, a preferred development of the invention provides that web-shaped sliding cams running in the axial direction are attached to three of the four outer surfaces of the corner connector, starting from the miter surface. At least one, preferably two or more sliding cams are attached to each of these three outer surfaces. The sliding cams ensure that the corner connector is connected to the hollow chamber profile in a slip-proof manner by a press fit in the area of the miter surface when it is pushed into the hollow chamber of the hollow chamber profile. The fourth outer surface, which is not provided with sliding cams, lies flat on an inner wall of the hollow chamber of the hollow chamber profile, so that the transmission of higher forces is also possible.
Nach einer weiteren bevorzugten Ausführungsform der Erfindung ist im Bereich der Gehrungsfläche des Eckverbinders ein als Anschlag dienender Vorsprung ausgebildet. Dieser ermöglicht das paßgenaue Einschieben des Eckverbinders mit einer vorherbestimmbaren Einschubt_<sfe so daß zum späteren Verschweißen der Eckverbinder ein definierter Schweißüberstand vorhanden ist.According to a further preferred embodiment of the invention, a projection serving as a stop is formed in the area of the miter surface of the corner connector. This enables the corner connector to be inserted precisely with a predeterminable insertion depth so that a defined welding projection is available for later welding of the corner connector.
Der erfindungsgemäße Eckverbinder kann sowohl zum Verbinden von Hohlkar-merprofilen aus thermoplastischen Kunststoffen als auch von Hohlkammerprofilen aus anderen Werkstoffen, z.B. Aluminium, eingesetzt werden. Ein bevorzugtes Einsatzgebiet ist jedoch das Verbinden von mit eingesetzten Metallprofilen verstärkten thermoplastischen Kunststoffprofilen. Hierzu werden die verstärkten Profile vor dem Einsetzen der Eckverbinder auf Gehrung geschnitten, wobei die Verstärkungsprofile bevorzugt gegenüber der thermoplastischen Ummantelung um einige mm zurückspringen, um eine Verschweißung zu ermöglichen. Der als Anschlag dienende Vorsprung des erfindungsgemäßen Eckverbinders ist dabei bevorzugt so ausgebildet, daß er an dem gegenüber dem Mantel des Hohlkammerprofils zurückspringenden Verstärkungsprofil anliegt, so daß die Schweiß fläche des Eckverbinders mit dem Mantel i-es Hohlkammerprofils bündig abschließt. Beim Verschweißen der Hohlkammerprofile mit den eingesetzten Eckverbindern wird in an sich bekannter V/eise ein Schweißschwert in die Gehrungsfläche eingeführt. Durch Anpressen der beiden Hohlkamr-erprof ile an das Schweißechwert wird die Schweißflache des Eckverbinders sowie der Rand des Hohlkammerprofils angeschmolzen. Durch anschließendes Herausziehen des SchweißschwertesThe corner connector according to the invention can be used both for connecting hollow chamber profiles made of thermoplastics and hollow chamber profiles made of other materials, e.g. aluminum. A preferred area of application, however, is the connection of thermoplastic profiles reinforced with inserted metal profiles. For this purpose, the reinforced profiles are mitred before the corner connectors are inserted, with the reinforcing profiles preferably setting back a few mm from the thermoplastic casing to enable welding. The projection of the corner connector according to the invention, which serves as a stop, is preferably designed in such a way that it rests against the reinforcing profile which sets back from the casing of the hollow chamber profile, so that the welding surface of the corner connector is flush with the casing of the hollow chamber profile. When welding the hollow chamber profiles to the inserted corner connectors, a welding blade is inserted into the miter surface in a manner known per se. By pressing the two hollow chamber profiles onto the welding blade, the welding surface of the corner connector and the edge of the hollow chamber profile are melted. By subsequently pulling out the welding blade
pe, und Anninanderpressen der Hohlkammerprofile wird eine feste Verschweißung erreicht.pe, and pressing the hollow chamber profiles together, a strong weld is achieved.
weist die Schweißfläche des EckverSinders eine gegliederte Oberfläche auf, um ein Abfließen des nehme IzFörmigen Kunststoffs beim Verschweißen zu ermijq liehen (siehe DE-OS 33 20 624 und DE-OS 25 36 839).The welding surface of the corner connector has a structured surface to enable the molded plastic to flow off during welding (see DE-OS 33 20 624 and DE-OS 25 36 839).

Es ist besonders vorteilhaft, die Außenkontur des Eckverbinders 1 um einige 10tel Millimeter kleiner zu wählen als die Innenkantur des Uerstärkungsprofils 11, so daß ein leichtes Einschieben des Eckverbinders 1 in die Hohlkammer 3 d@s Uerstärkungsprofils 11 möglich ist. pn the main chamber of the PV/C hollow chamber profile 2 and, if necessary, fixed in a force-locking manner. The hollow chamber 3 of the reinforcement profile 11 serves to accommodate the corner connector 1. For this purpose, the outer contour of the corner connector 1, which in the embodiment of the invention shown has a rectangular cross-section, is adapted to the hollow chamber 3 of the reinforcement profile 11. It is particularly advantageous to select the outer contour of the corner connector 1 to be a few tenths of a millimeter smaller than the inner edge of the reinforcement profile 11, so that the corner connector 1 can be easily pushed into the hollow chamber 3 of the reinforcement profile 11.

Der in den Figuren 1, 2 und 3 dargestellte Eckverbindür 1 weist sechs von der Gehrungsfläche h ausgehende Gleitnacken 9 auf, um eine kraftschlüssige Fixierung des Eckverbinders 1 in der Hohlkammer 3 zu ermöglichen. Die Gleitnocken 9 sind dabei nur an drei der vier Außenflächen &thgr; des Eckverbinders 1 angebracht, mit der vierten Außenfläche liegt der Eckverbinder 1 plan auf der entsprechenden Innenfläche des Verstärkungsprofils 11 auf. Auf diese liJeise ist eine definierte, Toleranzen ausgleichende Fixierung des Eckverbinders 1 in dem Hohlkammerprofil 2 bzw. dem V/erstärkungsprofil 11 möglich.The corner connector 1 shown in Figures 1, 2 and 3 has six sliding cams 9 extending from the miter surface h in order to enable a force-fitting fixation of the corner connector 1 in the hollow chamber 3. The sliding cams 9 are only attached to three of the four outer surfaces θ of the corner connector 1, with the fourth outer surface of the corner connector 1 lying flat on the corresponding inner surface of the reinforcement profile 11. In this way, a defined, tolerance-compensating fixation of the corner connector 1 in the hollow chamber profile 2 or the reinforcement profile 11 is possible.
Gemäß Figuren 1 und 3 weist der Eckverbinder 1 an der Gehrungsfläche k einen Vorsprung 10 auf, der diE Einschubtiefe des Eckverbinders 1 in dem Hohlkammerprofil 2 begrenzt. Im dargestellten Ausführungsbeispiel der Erfindung stößt dieser Vorsprung 1D an das Verstärkungsprofil 11 an, so daß die Gehrungsfläche k etwa h m: über das VErstärkungsprofil 11 übErsteht. Da das Verstärkungsprofil 11 seinerseits etwa U mm gegenüber der Gehrungsfläche des Hohlkammerprofils 2 zurückspringt, lieger die Gehrungsflächen des Eckverbinders 1 und des Hohlkammerprofils 2 etwa in einer Ebene. Beim Verschweißen zweier mit den erfindungsgemäßen Eckverbindern 1 versehener und auf Gehrung geschnittener Hohlkammerprofi1e 2 mittels eines Schweißschwertes wird sowohl die Gehrungsfläche des Hohlprofils 2 als auch des Eckverbinders 1 teilweise abgeschmolzp.n* Das dabei abgeschmolzene thermoplastische Material kann dabei ungehindert in die Nsben-HahlVammern 15 des HohlkammErprofils 2 sowie in die teilweise zurückspringende, also profilierte Gehrungsfläche U des Eckverbinderp 1 abfließen. Entsprechend Figur U und Figur 5 ist die Gehrungsfläche k in an sich bekannter Art durch Diagonalstege 16 sowie einen umlaufenden Steg profiliert.According to Figures 1 and 3, the corner connector 1 has a projection 10 on the miter surface k , which limits the insertion depth of the corner connector 1 in the hollow chamber profile 2. In the illustrated embodiment of the invention, this projection 1D abuts the reinforcing profile 11, so that the miter surface k projects approximately hm : beyond the reinforcing profile 11. Since the reinforcing profile 11 in turn recedes approximately 1 mm from the miter surface of the hollow chamber profile 2, the miter surfaces of the corner connector 1 and the hollow chamber profile 2 lie approximately in one plane. When welding two mitred hollow chamber profiles 2 provided with the corner connectors 1 according to the invention, using a welding blade, both the miter surface of the hollow profile 2 and the corner connector 1 are partially melted.* The thermoplastic material melted in the process can flow unhindered into the hollow chambers 15 of the hollow chamber profile 2 and into the partially recessed, i.e. profiled miter surface U of the corner connector 1. According to Figure U and Figure 5, the miter surface k is profiled in a manner known per se by diagonal webs 16 and a circumferential web.

in Verbindung mit einer axial angeordneten, zylindrischen Bohrung 7, die von der Gehrungsfläche 4 zum gegenüberliegenden Ende 5 reicht. In diese Bohrung 7 wird vor dem Einschieben des Eckverbinders 1 in die Hohlkammer 3 eine Schraube 12 eingeführt und in den Spreizkeil 13 eingeschraubt. Der Spreizkeil 13 (Figur 3) weist eine etwa kegelförmige Form auf, so daß beim Anziehen der Schraube 12 durch den Spreizkeil 13 eine Spreizung des Eckverbinders erfolgt. Um ein Drehen das Spreizkeils 13 in der Bohrung 7 beim Anziehen der Schraube 12 zu verhindern, weist der Spreizkeil 13 eine oder mehrere Rippen bzw. Stege 14 auf, die in die Spreizschlitze 6 des Eckverbinders 1 eingreifen.in connection with an axially arranged, cylindrical bore 7, which extends from the miter surface 4 to the opposite end 5. Before the corner connector 1 is inserted into the hollow chamber 3, a screw 12 is inserted into this bore 7 and screwed into the expansion wedge 13. The expansion wedge 13 (Figure 3) has an approximately conical shape, so that when the screw 12 is tightened, the expansion wedge 13 spreads the corner connector. In order to prevent the expansion wedge 13 from turning in the bore 7 when the screw 12 is tightened, the expansion wedge 13 has one or more ribs or webs 14, which engage in the expansion slots 6 of the corner connector 1.
Nach Einführen des Eckverbinders in die Hohlkammer 3 bis zum Anschlag des Vorsprungs 10 an dem Verstärkungsprofil 11 wird durch Anziehen der Schraube 12 und dadurch bewirktes Spreizen des Eckverbinders 1 an seinem der Gehrungsfläche 4 entgegengesetzten Ende 5 eine kraftschlüssige Verbindung zwischen dem Eckverbinder 1 und dem Vsrstärkungsprofil 11 bzw. dem Hoilkammerpro fil 2 bewirkt.After inserting the corner connector into the hollow chamber 3 until the projection 10 stops on the reinforcement profile 11, a force-fit connection is created between the corner connector 1 and the reinforcement profile 11 or the hollow chamber profile 2 by tightening the screw 12 and thereby spreading the corner connector 1 at its end 5 opposite the miter surface 4.
Es ist erfindungswesentlich, daß die Schraube 12 wenigstens so weit in den Eckverbinder zurückspringt, daß beim späteren Verschweißen die Schraube 12 nicht in die Schweißfläche ragt.It is essential to the invention that the screw 12 springs back into the corner connector at least so far that during subsequent welding the screw 12 does not protrude into the welding surface.
