Description

Technisches GebietTechnical field

Die Erfindung betrifft ein Fassadenprofil gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a facade profile according to the Preamble of claim 1.

Für die Anbringung von Fassaden an der Außenseite von Gebäuden werden üblicherweise eine Vielzahl von Fassadenprofilen verwendet, die zum einen als durchgehende, vertikale Pfosten und zum anderen als zwischen den Pfosten angebrachte Riegel verwendet werden. Hierdurch wird eine gitterartige Tragstruktur aufgebaut, an die zur Ausbildung der Fassadenfläche plattenförmige Elemente angebracht werden. Die Befestigung der plattenförmigen Elemente, beispielsweise Glasscheiben, erfolgt üblicherweise durch weitgehend streifenförmige Befestigungselemente, die im Bereich der Pfosten und Riegel an der Außenseite parallel zu diesen verlaufen und mittels Befestigungsschrauben an diesen festgelegt sind. Hierdurch werden die plattenförmigen Elemente zwischen den Fassadenprofilen und den daran angebrachten Befestigungsprofilen eingeklemmt und sicher gehalten. Zur Anbringung der Befestigungsprofile mittels zahlreicher Befestigungsschrauben ist in den Fassadenprofilen üblicherweise zumindest ein, im Querschnitt gesehen U-förmiger Schraubkanal ausgebildet. For attaching facades to the outside of Buildings are usually a variety of Facade profiles used, on the one hand as a continuous, vertical posts and other than between the posts attached latches can be used. This will create a lattice-like support structure built to the training plate-shaped elements are attached to the facade surface. The attachment of the plate-shaped elements, for example Panes of glass, usually done largely by strip-shaped fasteners in the area of Posts and transoms on the outside parallel to these run and by means of fastening screws on these are set. This will make the plate-shaped Elements between the facade profiles and those on them attached fastening profiles clamped and secure held. To attach the fastening profiles using numerous fastening screws is in the facade profiles usually at least one, seen in cross section U-shaped screw channel formed.

Stand der TechnikState of the art

Ein Fassadenprofil aus Edelstahl mit zumindest einem Schraubkanal ist in der DE 197 52 620 beschrieben. Aus Gründen der Korrosionsbeständigkeit sowie aus architektonischen Gründen ist die Verwendung von nicht rostendem oder austenitischem Edelstahl für Fassadenprofile vorteilhaft. Im Bauwesen, insbesondere im Außenwandbereich, ist in aller Regel als nichtrostender Stahl nur austenitischer Edelstahl zulässig. In der Bundesrepublik Deutschland geschieht dies im Rahmen einer allgemeinen bauaufsichtlichen Zulassung.A stainless steel facade profile with at least one Screw channel is described in DE 197 52 620. Out Reasons of corrosion resistance as well architectural reasons is the use of no rusting or austenitic stainless steel for facade profiles advantageous. In construction, especially in the outer wall area, is usually only as stainless steel austenitic stainless steel permitted. In the Federal Republic Germany does this as part of a general building inspectorate approval.

Das dominierende Herstellverfahren für Fassadenprofile ist Kaltumformen, vor allem Rollformen und Abkanten. Ausgangsmaterial ist in aller Regel 1-2 mm dickes Blech. Diese Materialdicken werden durch Kaltwalzen erreicht. Aufgrund des ausgeprägten Kaltverfestigungsgrades von austenitischen Edelstählen liegen damit schon im Halbzeug sehr hohe Festigkeitswerte vor (Zugfestigkeit, vor allem aber Dehngrenze und Härte).The dominant manufacturing process for facade profiles is Cold forming, especially roll forming and folding. The basic material is usually 1-2 mm thick sheet metal. These material thicknesses are achieved by cold rolling. Due to the pronounced degree of work hardening of austenitic stainless steels are already in the semi-finished product very high strength values (tensile strength, but above all Yield strength and hardness).

Die den Schraubkanal begrenzenden Wände werden hierbei zumeist durch eine Materialdoppelung ausgebildet. Mit anderen Worten ist das rollgeformte Edelstahlblech an den freien Enden des U-förmigen Schraubkanals um 180° umgeschlagen. Durch diese starke Umformung vergrößert sich insbesondere in diesen Bereichen die ohnehin vergleichsweise hohe Festigkeit des verwendeten Edelstahlblechs, so daß ein zufriedenstellendes Eindrehen von handelsüblichen Edelstahlschrauben in einen auf diese Weise ausgebildeten Schraubkanal nur schwierig möglich ist. Insbesondere treten Verformungen des Schraubengewindes auf, so daß nur geringe Ausziehkräfte und niedrige Überdrehmomente erreicht werden.The walls delimiting the screw channel become here mostly formed by double material. With others Words is the roll-formed stainless steel sheet on the free The ends of the U-shaped screw channel are turned through 180 °. This strong reshaping increases in particular these areas the comparatively high strength anyway of the stainless steel sheet used, so that a satisfactory screwing in of commercially available Stainless steel screws in a trained in this way Screw channel is difficult. In particular kick Deformations of the screw thread, so that only slight Extraction forces and low overtorques can be achieved.

Die DE 296 03 707 U1 beschreibt eine Metallfassade, insbesondere für Wintergärten, bei der die Glasscheiben so eingebaut werden sollten, daß die Scheibe nicht verspannt wird und zu Brüchen neigt. Daher soll das Gewicht der eingesetzten Glasscheiben oder Metallplatten optimal in die Metallfassade eingeleitet werden. Hierzu ist beabsichtigt, daß auf dem Befestigungskanal eine oder mehrere Glasauflagen vorgesehen sind, welche die Glasscheiben tragen. Das Gewicht der Glasscheiben kann über die Glasauflagen in die Metallfassade eingeleitet werden. Es besteht die Möglichkeit, die Glasauflagen mit den Befestigungskanälen durch Schrauben oder dergleichen zu verbinden, andererseits wird aber auch angeregt, die Glasauflagen mit den Holmen zu verschweißen, so daß das von den Glasauflagen aufgenommene Gewicht auf die Holme übertragen werden kann.DE 296 03 707 U1 describes a metal facade, in particular for conservatories where the glass panes are installed in this way should be that the disc is not stretched and too Breaks tends. Therefore, the weight of the used Glass panes or metal plates optimally in the metal facade be initiated. It is intended that Mounting channel one or more glass pads provided are who carry the glass panes. The weight of the Panes of glass can be placed on the glass facades in the metal facade be initiated. There is a possibility that Glass supports with the fastening channels by screws or to connect the same, but on the other hand also encouraged to weld the glass supports to the bars, so that the weight absorbed by the glass supports on the Spars can be transferred.

Aus der DE 94 11 552 U1 ist eine Fassade mit mehreren Holmen bekannt, die jeweils einen U-förmigen Schraubkanal aufweisen. Dieser kann aus Aluminium ausgebildet sein und in einem an dem Holm ausgebildeten Aufnahmekanal aus Stahl untergebracht und mit diesem verschweißt sein. Hierbei ergibt sich das Problem, daß ein derartiger Schraubkanal aus Aluminium eine vergleichsweise geringe Festigkeit aufweist und beispielsweise durch den Aufnahmekanal aus Stahl zusätzlich verstärkt werden muß. Ferner schmilzt Aluminium bei deutlich geringeren Temperaturen als Stahl, so daß ein Schraubkanal aus Aluminium unter Brandschutzgesichtspunkten nachteilig ist. Schließlich kann bei einer Verbindung eines Aluminiumbauteils mit einem Stahlprofil Kontaktkorrosion auftreten. An der Anordnung gemäß der genannten Druckschrift ist außerdem nachteilig, daß der Schraubkanal als gesondert einzuschiebendes Bauteil vorgesehen ist.DE 94 11 552 U1 is a facade with several spars known, each having a U-shaped screw channel. This can be made of aluminum and in one the spar designed receiving channel made of steel and be welded to it. This is the result Problem that such a screw channel made of aluminum has comparatively low strength and for example, through the steel receiving channel needs to be strengthened. Furthermore, aluminum melts significantly lower temperatures than steel, making a screw channel made of aluminum disadvantageous from a fire protection point of view is. Finally, when connecting a Aluminum component with a steel profile contact corrosion occur. On the arrangement according to the mentioned publication is also disadvantageous that the screw channel as a separate component to be inserted is provided.

Im Schraubkanal liegen die höchsten Belastungen vor. Daher wird der Schraubkanal in der Technik in der Regel aus einem besonders festen Material bzw. mit einer besonders großen Materialanhäufung gefertigt. Zwischen der Schraube und dem Schraubkanal liegt nur eine Linienberührung vor, über die neben der gesamten Windlast auf die Fassadenplatten sogar noch die Belastung durch die Fassadenplatten selbst aufgenommen werden muß. Daher wurde im Bereich des Schraubkanals im Stand der Technik stets ein besonders hochfestes Material eingesetzt.The highest loads are in the screw channel. Therefore In technology, the screw channel is usually made up of one particularly solid material or with a particularly large one Material accumulation manufactured. Between the screw and the Screw channel is only a line contact over which in addition to the total wind load on the facade panels nor the load from the facade panels themselves must be included. Therefore, in the area of Screw channel in the prior art is always a special one high-strength material used.

Darstellung der ErfindungPresentation of the invention

Der Erfindung liegt die Aufgabe zugrunde, ein Fassadenprofil aus Stahl zu schaffen, das mit möglichst geringem Aufwand so gestaltet werden kann, daß es sowohl hinsichtlich der Stabilität des Profils als auch der Stabilität des Schraubkanals den Anforderungen genügt, wobei gleichzeitig ein leichtes und sicher haltendes Eindrehen von Befestigungsschrauben in den Schraubkanal gestattet wird.The invention has for its object a facade profile to create from steel with as little effort as possible can be designed so that both in terms of Stability of the profile as well as the stability of the Screw channel meets the requirements, while at the same time an easy and secure holding of Fixing screws in the screw channel is allowed.

Die Lösung dieser Aufgabe erfolgt durch das im Anspruch 1 angegebene Fassadenprofil.This object is achieved by the in claim 1 specified facade profile.

Demzufolge zeichnet sich das erfindungsgemäße Fassadenprofil dadurch aus, daß auch der Schraubkanal aus einem Stahlwerkstoff, vorzugsweise Edelstahl, ausgebildet ist. Hierbei ist der Schraubkanal an einem getrennten, unmittelbar mit dem Tragprofil des Fassadenprofils verbundenen Bauteil vorgesehen. Dieses Bauteil kann bereits bei der Herstellung des Fassadenprofils bevorzugt durch Schweißen fest mit dem Tragprofil verbunden werden. Es sind keine gesondert handzuhabenden Bauteile oder dergleichen notwendig.Accordingly, the facade profile according to the invention is distinguished characterized in that the screw channel from a Steel material, preferably stainless steel, is formed. Here, the screw channel is on a separate, immediate component connected to the supporting profile of the facade profile intended. This component can already be manufactured the facade profile preferably by welding firmly to the Support profile can be connected. There are no separate ones components or the like to be handled.

Ferner lassen sich durch die Verwendung eines eigenen, jedoch fest mit dem Tragprofil verbundenen Bauteils für den Schraubkanal die Vorteile der Verwendung von Stahl hinsichtlich der Stabilität nutzen. Mit anderen Worten kann bei geringem Materialaufwand ein stabiler Schraubkanal hergestellt werden. Aufgrund der Kombination eines Schraubkanals aus Stahl mit einem aus Edelstahl gefertigten Fassadenprofil ergibt sich darüber hinaus der Vorteil, daß die Verbindung Stahl-Stahl beispielsweise durch Schweißen leicht hergestellt werden kann. Ferner sind keine Beeinträchtigungen der Korrosionsbeständigkeit zu befürchten.Furthermore, by using your own, however component firmly connected to the support profile for the Screw channel the benefits of using steel in terms of stability. In other words, it can a stable screw channel with low material requirements getting produced. Because of the combination of one Screw channel made of steel with a made of stainless steel Facade profile also has the advantage that the steel-steel connection, for example by welding can be easily manufactured. Furthermore, there are none To fear impairments of the corrosion resistance.

Erfindungsgemäß weist der Stahlwerkstoff des Schraubkanals eine geringere Festigkeit als der Profilwerkstoff auf. Der Grundgedanke der Erfindung besteht darin, zumindest für den Schraubkanal einen Edelstahlwerkstoff zu verwenden, der weicher ist als die üblicherweise für die Fassadenprofile verwendeten Werkstoffe. Für das Tragprofil kann hierbei in gewohnter Weise aufgrund der gegebenen Anforderungen hinsichtlich der Umformbarkeit, der detaillierten Konturgebung und aus wirtschaftlichen Gründen ein vergleichsweise dünnwandiger, äußerst harter austenitischer Edelstahl verwendet werden. Für das dafür getrennt vorgesehene Bauteil, das den Schraubkanal aufweist, wird erfindungsgemäß ein weicherer Stahlwerkstoff als der Werkstoff des Tragprofils verwendet. Hierdurch wird eine Deformierung des Schraubengewindes vermieden, und dadurch werden ausreichende Ausziehkräfte und ausreichende Überdrehmomente ermöglicht.According to the invention, the steel material of the screw channel a lower strength than the profile material. The The basic idea of the invention is, at least for the Screw channel to use a stainless steel material that is softer than that usually for the facade profiles used materials. For the support profile here as usual due to the given requirements in terms of formability, the detailed Contouring and for economic reasons comparatively thin-walled, extremely hard austenitic Stainless steel can be used. For that separately provided component, which has the screw channel according to the invention a softer steel material than that Material of the support profile used. This will create a Deformation of the screw thread avoided, and thereby sufficient pull-out forces and sufficient Overtorques allowed.

Bevorzugte Ausführungsformen der Erfindung werden in den weiteren Ansprüchen beschrieben.Preferred embodiments of the invention are described in the further claims described.

Um die genannten Eigenschaften des Schraubkanals an dem erfindungsgemäßen Fassadenprofil sicherzustellen, wird für den Edelstahlwerkstoff des Schraubkanals bevorzugt, daß dieser eine geringere Ausgangsfestigkeit und/oder einen geringeren Kaltwalzgrad und/oder einen geringeren Kaltverfestigungsgrad aufweist, was sich beispielsweise durch die Wahl einer geeigneten Legierung verwirklichen läßt. Ein geringerer Kaltwalzgrad läßt sich beispielsweise dadurch realisieren, daß für den Bereich des Schraubkanals eine dickere Wandstärke gewählt wird, so daß das für die Ausbildung des Schraubkanals verwendete Edelstahlblech beim Rollformen in geringerem Ausmaß verformt wird, und sich eine verglichen mit dem üblichen, 1 bis 2 mm dicken Edelstahlblech geringere Verfestigung einstellt. Dies ist auch für einen Stahlwerkstoff mit geringerer Ausgangsfestigkeit und/oder geringerem Kaltverfestigungsgrad, der durch Wahl einer geeigneten Legierung erreicht werden kann, der Fall, so daß sich durch die beschriebenen Maßnahmen das anforderungsgerechte Eindrehen von Befestigungsschrauben sicherstellen läßt. Ferner ist eine Kombination der vorangehend genannten Maßnahmen denkbar.To the mentioned properties of the screw channel on the Ensure facade profile according to the invention is for the stainless steel material of the screw channel preferred that this a lower initial strength and / or one lower degree of cold rolling and / or a lower Degree of work hardening, which is evident, for example, from the choice of a suitable alloy can be realized. On lower degree of cold rolling can be achieved, for example realize that for the area of the screw channel thicker wall thickness is chosen, so that for the Training of the screw channel used stainless steel sheet for Rollforms is deformed to a lesser extent, and one compared to the usual 1 to 2 mm thick stainless steel sheet sets lower consolidation. This is also for one Steel material with lower initial strength and / or lower degree of work hardening by choosing one suitable alloy can be achieved, so that the measures described screwing in fastening screws according to requirements can be ensured. Furthermore, a combination of the measures mentioned above conceivable.

Hierfür ist darüber hinaus die Verwendung von warmgewalztem Edelstahl für den Bereich des Schraubkanals vorteilhaft, da sich bei der Verformung eines derartigen Edelstahls eine Verfestigung einstellt, die nicht ein Ausmaß erreicht, bei dem das Eindrehen von Besfestigungsschrauben und deren sichere Halterung beeinträchtigt wird.For this is also the use of hot rolled Stainless steel advantageous for the area of the screw channel, because itself in the deformation of such a stainless steel Sets solidification that does not reach an extent at which the screwing of fastening screws and their secure bracket is compromised.

Im Hinblick auf die Gestaltung des Schraubkanals an dem Tragprofil mit Hilfe getrennter Bauteile oder Komponenten wird die Verwendung von Flachmaterial, von Winkelprofilen, eines U- und/oder W-Profils (vgl. Fig. 8 und zugehörige Beschreibung) bevorzugt, die jeweils mit dem Tragprofil verschweißt werden. Aus den beschriebenen Materialien läßt sich der Schraubkanal in einfacher Weise mit den angegebenen Eigenschaften ausbilden.With regard to the design of the screw channel on the Support profile with the help of separate parts or components the use of flat material, angle profiles, a U and / or W profile (see FIG. 8 and associated Description) preferred, each with the support profile be welded. From the materials described the screw channel in a simple manner with the specified Train properties.

Hierbei hat es sich für die Verwendung von Winkelprofilen oder eines U-Profils als vorteilhaft erwiesen, an diesem mehrere Ausnehmungen auszubilden, in denen jeweils eine Schweißverbindung ausgebildet ist. Hierdurch kann man für die Gestaltung des Schraubkanals beispielsweise aus zwei winkeloder L-förmigen Profilen, deren an dem Tragprofil festgelegte Schenkel voneinander wegweisen, den Vorteil erhalten, daß die Schweißverbindungen so ausgebildet werden können, daß diese bei Wirkung einer Kraft auf den jeweils anderen Schenkel mit einem geringeren Moment belastet werden. Dies gilt ebenso für Ausnehmungen im Bereich des mittleren Schenkels eines U-förmigen Profils, in denen das U-förmige Profil durch die Ausbildung von Schweißstellen befestigt werden kann, die mit einem vergleichsweise geringen Moment belastet werden.Here it has been used for the use of angle profiles or a U-profile proved to be advantageous on this form several recesses, in each of which one Welded connection is formed. This allows you to Design of the screw channel, for example, from two angles or L-shaped profiles, the ones fixed to the support profile Point the legs away from each other, get the advantage that the Welded connections can be designed so that these when a force acts on the other leg be charged at a lesser moment. This also applies to Recesses in the area of the middle leg of one U-shaped profile, in which the U-shaped profile through the Training of welds that can be fixed with be loaded at a comparatively small moment.

Für die Festlegung derjenigen Bauteile, die den Schraubkanal an dem Tragprofil bilden, hat es sich ferner als vorteilhaft erwiesen, in dem Tragprofil eine Ausnehmung auszubilden, in der beispielsweise ein U- oder W-Profil aufgenommen werden kann. Hierbei kann ein U-Profil beispielsweise in einer in dem Tragprofil ausgebildeten nutartigen Vertiefung eingesetzt und an der an die Nut anliegenden Kante verschweißt werden. Ferner ist es denkbar, an dem Tragprofil zwei freie Schenkel mit einer Lücke dazwischen vorzusehen, in die ein den Schraubkanal bildendes U-Profil eingesetzt wird, das mit den Enden der beiden freien Schenkel durch Schweißen verbunden wird. In ähnlicher Weise kann auf zwei freie Schenkel des Tragprofils ein weitgehend W-förmiges Profil aufgesetzt werden, das sich aus einem U-förmigen Profil dadurch ergibt, daß sich von den beiden freien Schenkeln eines U-förmigen Profils jeweils weitere Schenkel parallel zu den freien Schenkeln und außerhalb derselben zurück zu dem Niveau des Verbindungsabschnitts zwischen den beiden freien Schenkeln erstrecken. Hierdurch werden gewissermaßen zwei nebeneinander ausgebildete und durch den Verbindungsabschnitt miteinander verbundene U-Profile erhalten, die auf zwei an dem Tragprofil ausgebildete freie Schenkel derart aufgesteckt werden, daß sich der jeweilige freie Schenkel zwischen die beiden Schenkel der beschriebenen U-Profile erstreckt.For the definition of those components that the screw channel form on the support profile, it has also been found to be advantageous proven to form a recess in the support profile, in which can be recorded, for example, a U or W profile can. Here, a U-profile can, for example, in a the support profile formed groove-like recess used and welded to the edge of the groove. It is also conceivable to have two free legs on the support profile with a gap in between, into which the Screw channel forming U-profile is used, which with the Ends of the two free legs connected by welding becomes. Similarly, two free legs of the Carrying profile a largely W-shaped profile placed that results from a U-shaped profile that of a U-shaped of the two free legs Profiles each additional leg parallel to the free Thighs and outside of them back to the level of Connection section between the two free legs extend. As a result, two become side by side trained and through the connecting portion with each other get connected U-profiles on two on the support profile trained free legs are plugged in such a way that the respective free leg between the two Legs of the described U-profiles extends.

Ausführliche Beschreibung bevorzugter Ausführungsbeispiele der ErfindungDetailed description of preferred embodiments the invention

In Fig. 1 ist in der Schnittansicht das erfindungsgemäße Fassadenprofil 10 zu erkennen, das aus dem eigentlichen Tragprofil 12 und dem daran ausgebildeten Schraubkanal 14 besteht. Wie dies im Stand der Technik üblich ist, ist das Tragprofil 12 aus einem Edelstahlblech rollgeformt, so daß sich insgesamt eine geschlossene Form ergibt. Mit anderen Worten erstreckt sich das in der Zeichnung nur teilweise dargestellte Tragprofil 12 in den Bereich unterhalb der Fig. 1, so daß insgesamt ein Hohlprofil mit einem quadratischen oder rechteckförmigen Querschnitt ausgebildet wird. Selbstverständlich kann das Tragprofil 12 auch als offenes, U-förmiges Profil, als T- oder Doppel-T-Profil gestaltet sein.In Fig. 1 is the sectional view of the invention Facade profile 10 to recognize that from the actual Support profile 12 and the screw channel 14 formed thereon consists. As is common in the art, it is Support profile 12 roll-formed from a stainless steel sheet, so that the overall result is a closed form. With others Words extends only partially in the drawing shown support profile 12 in the area below the Fig. 1, so that a total of a hollow profile with a square or rectangular cross-section becomes. Of course, the support profile 12 as open, U-shaped profile, as a T or double T profile be designed.

An derjenigen Seite, an der bei der Verwendung die plattenförmigen Fassadenbauteile zu befestigen sind, ist ein Schraubkanal 14 ausgebildet, der erfindungsgemäß aus einem anderen, weicheren Material gebildet ist, als das Tragprofil 12. In dem gezeigten Fall wird der Schraubkanal durch zwei Leisten oder Bänder 16 aus Flachmaterial dargestellt, die weitgehend senkrecht auf der Stirnseite stehen. Diese sind parallel zueinander durch Schweißnähte 18 an der Stirnseite des Tragprofils 12 befestigt, so daß zwischen den Leisten 16 eine Befestigungsschraube derart eingedreht werden kann, daß ihr Gewinde mit den zueinander gerichteten Oberflächen der Leisten 16 in Eingriff kommt. Erfindungsgemäß ist der Werkstoff der Leisten 16 durch die vorangehend beschriebenen Maßnahmen ausreichend weich, so daß beispielsweise auch handelsübliche Befestigungsschrauben aus Edelstahl, die falls erforderlich zusätzlich diffusionsgehärtet sein können, mit ihrem Gewinde in den Werkstoff der Leisten 16 eindringen können, so daß sie sicher in dem Schraubkanal verankert sind.On the side where the plate-shaped facade components are to be fastened is a Screw channel 14 formed according to the invention from a different, softer material is formed than the support profile 12. In the case shown, the screw channel is replaced by two Bars or bands 16 made of flat material, the stand largely vertically on the front. These are parallel to each other by welds 18 on the end face of the support profile 12 attached so that between the strips 16th a fastening screw can be screwed in such that their thread with the facing surfaces of the Last 16 engages. According to the Material of the strips 16 by the previously described Measures sufficiently soft, so that for example commercially available fastening screws made of stainless steel, which if required can be additionally diffusion hardened with penetrate their thread into the material of the strips 16 can so that they are securely anchored in the screw channel.

Gemäß der Ausführungsform von Fig. 2 wird der Schraubkanal 14 anstelle der beiden Leisten 16 durch ein U-förmiges Profil 20 gebildet, das bei dem gezeigten Ausführungsbeispiel an seinem Fuß zu beiden Seiten durch außenseitige Schweißnähte 18 mit dem Tragprofil 12 fest verbunden ist. Hierdurch kann für das den Schraubkanal 14 bildende U-Profil 20 unabhängig von dem Werkstoff des Tragprofils 12 ein geeigneter Stahlwerkstoff gewählt werden, der die Festlegung der Schrauben nicht beeinträchtigt.According to the embodiment of FIG. 2, the screw channel 14 instead of the two strips 16 by a U-shaped profile 20 formed that in the embodiment shown on his Foot on both sides with outside welds 18 with the support profile 12 is firmly connected. This allows for the screw channel 14 forming U-profile 20 regardless of the Material of the support profile 12 is a suitable steel material be chosen, the fixing of the screws is not impaired.

In Fig. 3 ist in einer Draufsicht eine alternative Befestigungsmöglichkeit für das U-Profil 20 gezeigt. Dieses weist im Bereich seines mittleren Schenkels 22 (vgl. Fig. 2) mehrere Ausnehmungen 24 auf, die in diesem Fall, in der Draufsicht gesehen, weitgehend rechteckförmig sind. Die Schweißpunkte 18 können hierdurch im Bereich der Ausnehmungen 24 in dem mittleren Schenkel 22 ausgebildet werden, und müssen nicht, wie dies bei dem Ausführungsbeispiel von Fig. 2 der Fall ist, an der Außenseite des U-Profils 20 erstellt werden. Hierdurch ergibt sich aufgrund des geringeren, an den Verbindungsstellen in Form der Verschweißungen 18 wirkenden Hebelarms eine geringere Belastung dieser Verbindungsstellen. Selbstverständlich können die Verschweißungen 18 an beliebigen Rändern der bis zur stirnseitigen Oberfläche des Tragprofils durchgehenden Ausnehmungen 24 vorgenommen werden.3 is an alternative in a top view Attachment option for the U-profile 20 shown. This points in the area of its middle leg 22 (see FIG. 2) several recesses 24, which in this case, in the Seen from above, are largely rectangular. The As a result, welding spots 18 can be in the area of the recesses 24 are formed in the middle leg 22, and need not, as is the case with the embodiment of FIG. 2 the case is created on the outside of the U-profile 20 become. This results in the lower, to the Junctions acting in the form of welds 18 Lever arm a lower load on these joints. Of course, the welds 18 can any edges up to the front surface of the Support profile through recesses 24 are made.

In Fig. 4 ist wiederum in einer Schnittansicht eine weitere Ausführungsform des erfindungsgemäßen Fassadenprofils 10 gezeigt, bei dem der Schraubkanal 14 durch zwei Winkelprofile 26 gebildet wird, die weitgehend L-förmig sind. Diese beiden Winkelprofile 26 sind spiegelsymmetrisch zueinander angeordnet, so daß sich jeweilige erste Schenkel voneinander beabstandet und parallel zueinander erstrecken und den Schraubkanal 14 ausbilden. Die jeweiligen zweiten Schenkel erstrecken sich voneinander weg weisend und sind an dem Tragprofil 12 durch Schweißnähte 18 befestigt.4 is another sectional view Embodiment of the facade profile 10 according to the invention shown, in which the screw channel 14 by two angle profiles 26 is formed, which are largely L-shaped. These two Angle profiles 26 are mirror-symmetrical to one another arranged so that the respective first leg from each other spaced and parallel to each other and the Form screw channel 14. The respective second leg extend away from each other and are on the Support profile 12 attached by welds 18.

In Fig. 5 ist für eine derartige Ausführungsform mit zwei Winkelprofilen 26 eine alternative Art der Befestigung an dem Tragprofil 12 gezeigt. Ähnlich wie das in Fig. 3 gezeigte U-Profil 20 weisen die Winkelprofile 26 mehrere Ausnehmungen 24 auf, die als Einschnitte an den voneinander weg weisenden Schenkeln der Winkelprofile 26 gestaltet sind. Dadurch, daß an den Ausnehmungen 24 die Schweißpunkte 18 mit dem Tragprofil 12 näher an dem Schraubkanal 14 ausgebildet werden können, kann auch durch diese Modifikation erreicht werden, daß die Befestigungsstellen in Form der Schweißpunkte 18 durch geringere Momente belastet werden. Gleichzeitig gewährleisten die zwischen den Ausnehmungen 24 verbleibenden Bereiche eine hinreichende Stabilität gegen ein nach außen Schwenken der Winkelprofile 26 beim Eindrehen der Befestigungsschrauben in den zwischen den Profilen 26 gebildeten Schraubkanal 14.5 is for such an embodiment with two Angle profiles 26 an alternative way of attachment to the Support profile 12 shown. Similar to the U-profile shown in Fig. 3 20, the angle profiles 26 have a plurality of recesses 24 on, as incisions on the facing away from each other Legs of the angle profiles 26 are designed. As a result of that at the recesses 24, the welding spots 18 with the Support profile 12 are formed closer to the screw channel 14 can also be achieved through this modification, that the attachment points in the form of the weld spots 18th be burdened by lower moments. simultaneously ensure the remaining between the recesses 24 Areas of sufficient stability against an outside Swiveling the angle profiles 26 when screwing in Fastening screws in the between the profiles 26 formed screw channel 14.

Fig. 6 zeigt beispielhaft für ein U-Profil 20 eine Möglichkeit, wie an dem Tragprofil 12 Maßnahmen für eine genaue Positionierung der den Schraubkanal 14 bildenden Komponenten erreicht werden kann. Hierbei ist das Tragprofil 12 an seiner Stirnseite mit einer nut- oder kanalförmigen Vertiefung 28 versehen, die weitgehend senkrecht zur Stirnseite verlaufende Flanken aufweist und ohne weiteres während der Rollformung des Tragprofils 12 ausgebildet werden kann. In diese Vertiefung 28 kann das U-Profil 20 aus einem geeigneten anderen Werkstoff paßgenau eingesetzt und durch Schweißnähte 18 mit dem Tragprofil 12 verbunden werden.6 shows an example of a U-profile 20 Possibility of 12 measures for a on the support profile exact positioning of the screw channel 14 forming Components can be achieved. Here is the support profile 12 on its end face with a groove or channel-shaped Provide depression 28 which is substantially perpendicular to Has end flanks and easily are formed during the roll forming of the support profile 12 can. In this recess 28, the U-profile 20 from one suitable other material used and fit through Welds 18 are connected to the support profile 12.

Fig. 7 zeigt eine ähnliche Maßnahme zur Positionierung eines den Schraubkanal 14 bildenden U-Profils 20. In diesem Fall ist das Tragprofil 12 nicht als geschlossenes Hohlprofil ausgebildet, sondern ist an seiner Stirnseite mit einer Öffnung versehen, die durch zwei freie, weitgehend senkrecht zur Stirnseite stehende Schenkel 30 begrenzt wird. In die Lücke oder den Zwischenraum zwischen diesen Schenkeln 30 wird das U-Profil 20 eingesetzt und durch Schweißnähte 18 mit dem Tragprofil 12 verbunden. In vorteilhafter Weise sind die Schweißnähte 18 an den freien Enden der Schenkel 30 und an die jeweilige Außenseite der Schenkel des U-Profils 20 anliegend vorgesehen. Selbstverständlich ist es denkbar, daß die Schenkel 30 kürzer gestaltet werden, so daß sie ähnlich wie bei der Ausführungsform von Fig. 6 an einer Stelle entlang der Längserstreckung der Schenkel des U-Profils 20 mit diesen verbunden sind.Fig. 7 shows a similar measure for positioning a the screw channel 14 forming U-profile 20. In this case the support profile 12 is not a closed hollow profile trained, but is on its face with a Opening provided by two free, largely vertical leg 30 standing on the end face is limited. In the Gap or the space between these legs 30 will the U-profile 20 inserted and welded 18 with the Support profile 12 connected. Advantageously, the Welds 18 at the free ends of the legs 30 and the respective outside of the legs of the U-profile 20 provided attached. Of course, it is conceivable that the legs 30 are made shorter so that they are similar as in the embodiment of Fig. 6 at one point along the longitudinal extent of the legs of the U-profile 20 associated with them.

In Fig. 8 ist eine weitere Ausführungsform des Fassadenprofils 10 gezeigt, bei dem ein weitgehend W-förmiges Profil zur Ausbildung des Schraubkanals 14 verwendet wird, wobei das W-Profil 32 gemäß der Darstellung von Fig. 8 als umgekehrtes W erscheint. Das Profil 32 ergibt sich aus dem in Fig. 7 gezeigten U-Profil 20 gewissermaßen dadurch, daß parallel zu den beiden Schenkeln des U-Profils 20 jeweils außerhalb der beiden Schenkeln und parallel zu diesen weitere Schenkel 34 vorgesehen sind, die zusammen mit den freien Schenkeln des U-Profils, von dem gedanklich ausgegangen wurde, einen Zwischenraum definieren, in den sich der jeweilige Schenkel 30 des Tragprofils 12 .erstreckt. Die Befestigung des W-Profils 32 erfolgt in dem gezeigten Fall durch Verschweißung an den Enden der beiden Schenkel 34. In dieser Ausführungsform ist das den Schraubkanal 14 bildende Profil 32 bezüglich des Tragprofils 12 nicht nur in einer seitlichen Richtung (d.h. von links nach rechts gemäß Fig. 8, sondern auch in der Tiefenrichtung, d.h. von oben nach unten gemäß Fig. 8) festgelegt. Bei der Wahl eines geeigneten Werkstoffs für das Profil 32 kann trotz der vergleichsweise umfangreichen Verformung dieses Profils wie für die vorangehend beschriebenen Schraubkanal-Profile sichergestellt werden, daß es hinreichend weich bleibt, um ein zufriedenstellendes Eindrehen von Befestigungsschrauben zu gestatten. Alternativ kann das Profil 32 auch warm verformt sein, so daß die vor der Verformung vorhandene Festigkeit wieder hergestellt wird.8 is another embodiment of the Facade profile 10 shown, in which a largely W-shaped Profile is used to form the screw channel 14 the W profile 32 as shown in FIG. 8 as inverted W appears. The profile 32 results from the in Fig. 7 shown U-profile 20 to a certain extent that parallel to the two legs of the U-profile 20 each outside of the two legs and parallel to these further Legs 34 are provided, which together with the free Legs of the U-profile, from which it is thought was to define a space in which the respective leg 30 of the support profile 12. The Fastening of the W profile 32 takes place in the case shown by welding at the ends of the two legs 34. In this embodiment is that which forms the screw channel 14 Profile 32 with respect to the support profile 12 not only in one lateral direction (i.e. from left to right according to Fig. 8, but also in the depth direction, i.e. from top to bottom according to FIG. 8). When choosing a suitable one Material for the profile 32 can be comparatively despite the extensive deformation of this profile as for the ensured screw channel profiles described above be that it remains sufficiently soft to a satisfactory screwing in of fastening screws allow. Alternatively, the profile 32 can also be thermoformed be so that the existing strength before deformation is restored.
