Description

Die Erfindung bezieht sich auf ein Hohlkammerprofil mit einer in dessen Hohlkammer einsteck- und mit einem weiteren Profil oder dergl. verschraub- oder sonstwie verbindbaren Armierung für die Versteifung und Verbindung von Fenster-, Tür- und sonstigen Profilen, wie beispielsweise Kämpfer- und Pfostenprofile, wobei die Armierung aus einem gewalzten kastenförmigen Stahlblechprofil besteht, einen Schraubkanal für die stirnseitige Verschraubung mit dem weiteren Profil besitzt und an den Innenwänden der Hohlkammer entlangläuft. Hohlkammerprofile, beispielsweise aus Kunststoff bestehende Profile mit Armierungen sind notorisch bekannt. Die Armierungen sind dabei meist aus Aluminium oder Stahlblech gefertigt, wobei Armierungen aus Aluminiumprofilen einerseits zu teuer und andererseits zu wenig belastbar (nur etwa 1/3 der Biegesteifigkeit von Stahl) sind. Deswegen werden Armierungen aus Stahlblech für Hohlkammerprofile bevorzugt, sie sind daher auch an sich allgemein bekannt. Diese Armierungen weisen u.a. Kasten- oder Z-, Doppel-T- etc. -formen auf.The invention relates to a hollow chamber profile with an insertable in its hollow chamber and with another profile or the like. Screwable or otherwise connectable reinforcement for the stiffening and connection of window, door and other profiles, such as fighter and post profiles, wherein the reinforcement consists of a rolled box-shaped sheet steel profile, has a screw channel for screwing on the end face with the further profile and runs along the inner walls of the hollow chamber. Hollow chamber profiles, for example plastic profiles with reinforcements, are notoriously known. The reinforcements are mostly made of aluminum or sheet steel, whereby reinforcements made of aluminum profiles are on the one hand too expensive and on the other hand too little resilient (only about 1/3 of the bending stiffness of steel). For this reason, reinforcements made of sheet steel are preferred for hollow chamber profiles and are therefore also generally known per se. These reinforcements include Box or Z, double T, etc. shapes.

Mit dem GM 87 14 076 (EP-PS 0 312 646) ist ein Mittelträger für Kunststoff-Fensterrahmen bekannt geworden, bei dem der Profileinsatz aus zwei gleichen aber spiegelbildlich zueinander angeordneten Profilhälften besteht, die je die Grundform eines "U" aufweisen und mit dem Basisschenkel gegeneinander angeordnet sind, wobei jeder Basisschenkel zwei in einem Abstand parallel zueinander und in Längsrichtung verlaufende Sicken aufweist, die gemeinsam zwei Schraubenkanäle bilden und die Schenkelabmessungen jeder Profilhälfte so gewählt sind, daß der Gesamteinsatz mit geringem Spiel in den Blendholm einsetzbar ist, so, daß in die Schraubenkanäle eingesetzte Schrauben durch Spreizung dieses Spiel auspressen können. Ein solcher aus zwei lose in die Hohlkammer eingesetzten Profilhälften bestehender Profileinsatz weist jedoch mehrere Nachteile auf. So werden z.B. die Schraubkanäle für die Kämpferschrauben erst dann gebildet, wenn die beiden Profilhälften exakt aneinanderliegen, d.h. die Sicken in den Profilhälften müssen zusammen je eine obere und eine untere quadratische Aussparung (Schraubkanal) bilden, in die dann Schrauben eingedreht werden können. Hat das Hohlkammerprofil jedoch auch nur geringe Höhentoleranzen, liegen sich die Sicken nicht genau gegenüber und ein Schraubkanal bildet sich nicht ohne Nacharbeit. Bei Quertoleranzen des Hohlkammerprofiles verkanten sich die beiden Profilhälften und ein Eindrehen der Schrauben ist ebenfalls nicht ohne weiteres möglich. Ein zusätzlicher Nachteil ist darin zu sehen, daß sich die Profilhälften mit ihrem Kopf- und Fußfalz an der Innenwand des Hohlkammerprofiles abstützen müssen, um überhaupt funktionsfähig zu sein. Nach Eindrehen der Schrauben verpressen sich diese Falze in das Kunststoffmaterial, was zu Kaltfluß des Kunststoffes und ggf. auf Dauer zum Lockern der Schrauben führt. Die Montage der Profilhälften gestaltet sich darüber hinaus umständlich und zeitaufwendig. Außerdem neigen derartige Profileinsätze bei längeren Profilen zu erheblicher Geräuschentwicklung.With the GM 87 14 076 (EP-PS 0 312 646) a central support for plastic window frames has become known, in which the profile insert consists of two identical but mirror-inverted profile halves, each having the basic shape of a "U" and with which Base legs are arranged against each other, each base leg having two beads running parallel to one another and in the longitudinal direction at a distance, which together form two screw channels and the leg dimensions of each profile half are selected so that the entire insert can be inserted into the blind beam with little play, so that screws inserted into the screw channels can be pressed out by spreading this play. However, such a profile insert consisting of two profile halves inserted loosely into the hollow chamber has several disadvantages. For example, the screw channels for the fighter screws are only formed when the two profile halves lie exactly against each other, i.e. the beads in the profile halves must together form an upper and a lower square recess (screw channel) into which screws can then be screwed. However, if the hollow chamber profile also has only small height tolerances, the beads are not exactly opposite one another and a screw channel does not form without rework. In the case of transverse tolerances of the hollow chamber profile, the two profile halves tilt and screwing in of the screws is also not easily possible. An additional disadvantage is the fact that the profile halves must be supported with their top and bottom folds on the inner wall of the hollow chamber profile in order to be functional at all. After the screws have been screwed in, these folds press into the plastic material, which leads to the cold flow of the plastic and possibly to the screws loosening in the long run. The assembly of the profile halves is also cumbersome and time-consuming. In addition, such profile inserts tend to generate considerable noise in the case of longer profiles.

Das in der DE-PS 40 20 559 angegebene Hohlkammerprofil ist mit einer einstückig ausgebildeten Armierung mit einem einseitig offenen Schraubkanal ausgerüstet und vermeidet dadurch die Nachteile des DE-GM G 87 14 076, weist aber den Nachteil auf, daß externe Elemente, wie beispielsweise Beschläge oder dergl. nicht mit dem Armierungsprofil, das etwa in der Mitte der Hohlkammer verläuft, verschraubbar sind, sondern nur mit der Kunststoffwand des Hohlkammerprofiles und somit diese besonders belasten können.The hollow chamber profile specified in DE-PS 40 20 559 is equipped with a one-piece reinforcement with a screw channel open on one side and thereby avoids the disadvantages of DE-GM G 87 14 076, but has the disadvantage that external elements, such as fittings or the like. Cannot be screwed to the reinforcing profile, which runs approximately in the middle of the hollow chamber, but only to the plastic wall of the hollow chamber profile and thus can particularly stress it.

Der Erfindung, wie sie in den Ansprüchen beschrieben ist, liegt daher die Aufgabe zugrunde, ein armiertes Hohlkammerprofil beispielsweise aus Kunststoff zu schaffen, mit dem der Gegenstand der DE-PS 40 20 559 verbessert wird und das eine erhöhte Windbelastung vor allem bei Rahmenkonstruktionen aufzunehmen in der Lage ist, bei dem ferner eine Verformung des Hohlkammerprofiles durch einseitige Temperaturbelastung nicht auftritt und zusätzlich die sichere Montage von externen Elementen, wie z.B. Beschlägen usw. an das Hohlkammerprofil gestattet.The invention, as described in the claims, is therefore based on the object to provide a reinforced hollow chamber profile, for example made of plastic, with which the subject matter of DE-PS 40 20 559 is improved and which absorb an increased wind load, particularly in frame structures is capable of furthermore, in which a deformation of the hollow chamber profile due to one-sided temperature stress does not occur and, in addition, the secure mounting of external elements, such as Fitting etc. on the hollow chamber profile allowed.

Durch die Ausrüstung des Hohlkammerprofiles mit einer Armierung als offenes oder geschlossenes einstückiges Stahlblechprofil mit einem oder mehreren einseitig offenen Kanälen z.B. Schraubkanälen innerhalb der um die Innenwand der Hohlkammer verlaufenden Schenkel des Armierungsprofiles, wobei diese Schraubkanäle aus dem Stahlblech des Armierungsprofiles geformt sind, werden mehrere Vorteile gleichzeitig erzielt, nämlich

  • a) eine wesentlich höhere Beaufschlagung des Hohlkammerprofiles mit Windlasten und vor allem einseitig auftretenden Temperaturbelastungen ermöglicht,
  • b) die Möglichkeit die Hohlkammer, wenn geboten, vollständig mit dem Armierungsprofil auszukleiden um möglichst hohe Trägheitsmomente sowohl in der X-als auch der Y-Achse zu erreichen, was auch dadurch ermöglicht ist, daß die Armierung weit von der neutralen Zone des Hohlkammerprofiles entfernt vorgesehen ist,
  • c) die sichere Anbringung von externen Elementen, wie beispielsweise Beschlägen usw., ohne daß befürchtet werden muß, daß unter extremen Belastungen, der Kunststoff der Hohlkammer ausreißt, wobei das Stahlblechprofil parallel zur Außen- bzw. Innenwand des Hohlkammerprofiles angeordnet ist und dadurch diese Elemente an beliebiger Stelle der Kunststoffprofil-Außenwand angebracht werden können, da sie mit der Armierung direkt fest verbunden, z.B.verschraubt sind,
  • d) wegen der Anordnung des, bzw. der Verbindungskanäle, z.B. Schraubkanäle in der neutralen Zone der Hohlkammerprofiles können u.a. T- und Kreuzstöße etc. unproblematisch hergestellt werden,
  • e) hohe Formstabilität und Maßhaltigkeit durch die einstückige Ausbildung der Armierung,
  • f) einfaches Anpassen der Form der Armierung sowie des, bzw. der Schraubkanäle und der Plazierung an die jeweiligen Gegebenheiten des Hohlkammerprofiles und der vorgegebenen Anforderungen hinsichtlich Anbringung der externen Elemente, Stabilität, des gesamten Profiles, Konstruktionsvarianten usw. und
  • g) Möglichkeit der Materialeinsparung bei der Konstruktion des Hohlkammerprofils aufgrund hoher Festigkeitswerte der einstückigen Armierung und der einfachen Verkleidung der Armierung mit einfachen Profilen, insbesondere Kunststoffprofilen.
By equipping the hollow chamber profile with a reinforcement as an open or closed one-piece sheet steel profile with one or more channels open on one side, for example screw channels within the leg of the armoring profile running around the inner wall of the hollow chamber, these Screw channels are formed from the steel sheet of the reinforcement profile, several advantages are achieved simultaneously, namely
  • a) allows a significantly higher exposure of the hollow chamber profile to wind loads and, above all, one-sided temperature loads,
  • b) the possibility of completely lining the hollow chamber, if required, with the reinforcement profile in order to achieve the highest possible moments of inertia in both the X and Y axes, which is also made possible by the fact that the reinforcement is far from the neutral zone of the hollow chamber profile is provided,
  • c) the secure attachment of external elements, such as fittings, etc., without fear that the plastic of the hollow chamber tears out under extreme loads, the steel sheet profile being arranged parallel to the outer or inner wall of the hollow chamber profile and thereby these elements can be attached anywhere on the plastic profile outer wall, as they are directly connected to the reinforcement, e.g. screwed,
  • d) because of the arrangement of the or the connecting channels, for example screw channels in the neutral zone of the hollow chamber profile, T and cross joints etc. can be produced without problems,
  • e) high dimensional stability and dimensional stability due to the one-piece design of the reinforcement,
  • f) easy adaptation of the shape of the reinforcement and / or the screw channels and the placement to the respective conditions of the hollow chamber profile and the specified requirements with regard to attachment of the external elements, stability, the entire profile, construction variants etc. and
  • g) Possibility of saving material in the construction of the hollow chamber profile due to the high strength values of the one-piece reinforcement and the simple covering of the reinforcement with simple profiles, in particular plastic profiles.

Die Erfindung ist nachstehend anhand eines in den Abbildungen dargestellten Ausführungsbeispieles näher erläutert.The invention is explained below with reference to an embodiment shown in the figures.

Es zeigt:

  • Fig. 1 ein armiertes Hohlkammerprofil gem. der Erfindung
  • Fig. 2 eine Ausführungsvariante der Figur 1
  • Fig. 3 eine beispielsweise Armierung
  • Fig. 4 die Explosionsdarstellung einer Hohlkammerprofilverbindung und
  • Fig. 5 verschiedene Ausführungsvarianten der Armierung.
Die Figuren 1 und 2 zeigen je ein Hohlkammerprofil 1 bzw. 4 beispielsweise aus Kunststoff mit einer in deren Hohlkammer H eingeschobenen Armierung 2 oder 5 (Fig. 2). Die Armierung 2 ist aus einem einschalig gewalztem Stahlblechprofil gefertigt, somit einstückig ausgebildet und besitzt im Inneren dieses Profiles einen Kanal z.B. einen Schraubkanal 2a, von dem zwei Schenkel 2b ausgehen, die einen etwa V-förmigen, sich zur Wand der Hohlkammer H hin öffnenden Spalt S begrenzen. Dieser Spalt kann auch, wie in Figur 2 dargestellt, schmal ausgebildet und von zwei beispielsweise parallelen Schenkeln 5b begrenzt sein. Die beiden freien Schenkel 2a bzw. 5a sind in Höhe der Innenwand des Hohlkammerprofiles 1 bzw. 4 abgewinkelt und verlaufen als Schenkel 2c bzw. 5c um die Innenwand des Hohlkammerprofiles 1 bzw. 4 herum, so daß sich deren Enden 2d bzw. 5d an der dem Spalt S gegenüberliegenden Innenwand des Hohlkammerprofiles 1 bzw. 4 mit etwas Abstand gegenüberstehen. In Fig. 2 unterer Teil ist ersichtlich, daß die Armierung nicht etwa parallel zu den Innenwänden der Hohlkammer verlaufen muß, sie kann vielmehr auch in beliebigen Winkel zu den Innenwänden der Hohlkammer (H) des Hohlkammerprofiles (4) verlaufen, nur zwei Berührungspunkte zwischen Kunststoffinnenwand und Armierung (5) sind erforderlich, wobei auf diese Berührungspunkte nur minimaler Druck ausgeübt wird, so daß Kaltfluß nicht entstehen kann. Die Enden 2d bzw. 5d der Armierung 2 bzw. 4 können auch, miteinander verbunden, z.B. verschweißt sein, oder sich etwas überlappen. Mit 3 ist ein Befestigungsmittel z. B. eine Schraube für die stirnseitige Verbindung der Armierung 2, z.B. in der Fenster- und Türentechnik, eines als Pfostenprofil ausgebildeten Hohlkammerprofils 1 bzw. 4 mit einem weiteren Profil, z.B. einem Kämpferprofil 6 wie in Fig. 4 dargestellt.It shows:
  • Fig. 1 shows a reinforced hollow chamber profile. the invention
  • 2 shows an embodiment variant of FIG. 1
  • 3 shows an example of reinforcement
  • Fig. 4 shows the exploded view of a hollow chamber profile connection and
  • Fig. 5 different variants of the reinforcement.
Figures 1 and 2 each show a hollow chamber profile 1 or 4, for example made of plastic with a reinforcement 2 or 5 inserted into the hollow chamber H (FIG. 2). The reinforcement 2 is made from a single-shell rolled sheet steel profile, thus formed in one piece and has in the interior of this profile a channel, for example a screw channel 2a, from which two legs 2b extend, which have an approximately V-shaped gap that opens towards the wall of the hollow chamber H. S limit. As shown in FIG. 2, this gap can also be narrow and delimited by two legs 5b, for example parallel. The two free legs 2a and 5a are angled at the level of the inner wall of the hollow profile 1 and 4 and extend as legs 2c and 5c around the inner wall of the hollow profile 1 and 4, so that their ends 2d and 5d on the the inner wall of the hollow chamber profile 1 or 4 opposite the gap S are spaced a little apart. In Fig. 2 lower part it can be seen that the reinforcement does not have to run approximately parallel to the inner walls of the hollow chamber, rather it can also run at any angle to the inner walls of the hollow chamber (H) of the hollow chamber profile (4), only two points of contact between the plastic inner wall and reinforcement (5) are required, only minimal pressure being exerted on these contact points, so that cold flow cannot occur. The ends 2d and 5d of the reinforcement 2 and 4 can also be connected to one another, for example welded, or overlap somewhat. With 3 is a fastener such. B. a screw for the front connection of the reinforcement 2, for example in window and door technology, a hollow profile 1 or 4 designed as a mullion profile with a further profile, for example a fighter profile 6 as shown in FIG. 4.

Die Figur 3 zeigt eine beispielsweise Armierung 6. Bei diesem Profil, das etwa E-Form aufweist, stehen sich die beiden Enden 6d des Profiles nicht gegenüber, vielmehr enden sie parallel als freie Schenkel, beispielsweise nahe der Ecken der Hohlkammer H.FIG. 3 shows, for example, reinforcement 6. In this profile, which is approximately E-shaped, the two ends 6d of the profile do not face each other, but rather end in parallel as free legs, for example near the corners of the hollow chamber H.

In Figur 4 ist eine Hohlkammerprofilverbindung dargestellt, bei der ein Hohlkammerprofil 4, z.B. ein Pfostenprofil und ein weiteres Hohlkammerprofil 7, z.B. ein Rahmen- oder Kämpferprofil über eine Schraube 3, die durch das Hohlkammerprofil 7 und dessen Armierung 7a hindurch in den Schraubkanal 5a der Armierung 5 stirnseitig eingreift, verbunden. Ein externes Element 8, z.B. ein Beschlag, ist dabei durch das Kunststoffmaterial des Hohlkammerprofiles 4 hindurch mit der Armierung 5 in der Hohlkammer H fest verschraubt.
Einige erfindungsgemäße Ausführungsvarianten der Armierung des Hohlkammerprofiles sind in der Figur 5 dargestellt, wobei die Aufzählung solcher Profile nicht vollständig ist. Die Form der Armierung kann den jeweiligen Erfordernissen angepaßt werden, ohne den allgemeinen Erfindungsgedanken zu verlassen. So zeigt Fig. 5I eine Ausführungsvariante bei der der vom Schraubkanal 9a der Armierung 9 ausgehende Spalt S in Richtung einer Schmalseite der Hohlkammer H gem. Fig. 1 verläuft. Das Profil der Armierung 9 ist beispielsweise geschlossen, die Enden desselben sind z.B. miteinander verschweißt. Fig. 5II zeigt eine Armierung 10 mit zwei Schraubkanälen 10a und 10b, während die Fig. 5III ein Stahlblechprofil 11 zeigt, dessen Profil einer vorgegebenen Kontur der Hohlkammer H eines Hohlkammerprofiles angepaßt ist. Die Enden der freien Schenkel 12 der Armierung gem. Fig. 5IV sind gefalzt, um eine besondere Steifigkeit der Außenflanken zu erzielen. Die Profile 13 bis 16 sind beispielsweise mit aufeinandergewalzten freien Schenkeln der Schraubkanäle 13a bis 16a dargestellt. Die freien Schenkel können beispielsweise auch zusätzlich mit Schweißnähten 14c und/oder 14d miteinander fest verbunden sein, so daß sich ein rigides Profil ergibt.FIG. 4 shows a hollow chamber profile connection in which a hollow chamber profile 4, for example a post profile and a further hollow chamber profile 7, for example a frame or fighter profile, via a screw 3 which passes through the hollow chamber profile 7 and its reinforcement 7a into the screw channel 5a of the reinforcement 5 engages on the face, connected. An external element 8, for example a fitting, is firmly screwed through the plastic material of the hollow chamber profile 4 to the reinforcement 5 in the hollow chamber H.
Some embodiment variants of the reinforcement of the hollow chamber profile according to the invention are shown in FIG. 5, the list of such profiles not being exhaustive. The shape of the reinforcement can be adapted to the respective requirements without leaving the general idea of the invention. 5I shows an embodiment variant in which the gap S starting from the screw channel 9a of the reinforcement 9 in the direction of a narrow side of the hollow chamber H according to FIG. Fig. 1 runs. The profile of the reinforcement 9 is closed, for example, the ends of which are welded together, for example. Fig. 5II shows a reinforcement 10 with two screw channels 10a and 10b, while Fig. 5III shows a steel sheet profile 11, the profile of which is adapted to a predetermined contour of the hollow chamber H of a hollow chamber profile. The ends of the free legs 12 of the reinforcement acc. 5IV are folded to achieve a special stiffness of the outer flanks. The profiles 13 to 16 are shown, for example, with free legs of the screw channels 13a to 16a rolled onto one another. The free legs can, for example, also be firmly connected to one another with weld seams 14c and / or 14d, so that a rigid profile results.

Selbstverständlich ist das beschriebene Hohlkammerprofil mit der Armierung nicht auf das beschriebene Ausführungsbeispiel und die Verbindung des Pfostenprofiles mit dem Kämpferprofil eines Fensterrahmens beschränkt. Es kann auch auf anderen Gebieten des Einsatzes von Hohlkammerprofilen mit Vorteil eingesetzt werden, so z.B. außer bei Fensterrahmen, bei Türrahmen, Dächern, Geländern, Wintergärten, Gewächshäusern, Hallen usw.Of course, the described hollow chamber profile with the reinforcement is not limited to the described embodiment and the connection of the post profile with the fighter profile of a window frame. It can also be used to advantage in other areas of the use of hollow chamber profiles, for example except for window frames, door frames, roofs, railings, winter gardens, greenhouses, halls, etc.
