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 the attachment of facades on the outside of buildings, a variety of facade profiles are usually used, which are used on the one hand as a continuous, vertical post and on the other hand as a transom attached between the posts. In this way, a grid-like support structure is built, to which plate-shaped elements are attached to form the facade surface. The plate-shaped elements, for example glass panes, are usually fastened by largely strip-shaped fastening elements which run parallel to them on the outside in the area of the posts and transoms and are fastened to them by means of fastening screws. As a result, the plate-shaped elements between the facade profiles and the attached mounting profiles are clamped and held securely. To attach the fastening profiles by means of numerous fastening screws, at least one screw channel, seen in cross section, is usually formed in the facade profiles.

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. For reasons of corrosion resistance and for architectural reasons, the use of stainless or austenitic stainless steel for facade profiles is advantageous. In construction, especially in the outer wall area, only austenitic stainless steel is generally permitted as stainless steel. In the Federal Republic of Germany, this is done 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 strain hardening of austenitic stainless steels, very high strength values are already available in the semi-finished product (tensile strength, but above all proof 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 are usually formed by a double material. In other words, the roll-formed stainless steel sheet is turned over by 180 ° at the free ends of the U-shaped screw channel. This strong reshaping increases the already comparatively high strength of the stainless steel sheet used, particularly in these areas, so that it is difficult to screw commercially available stainless steel screws into a screw channel designed in this way. In particular, deformation of the screw thread occurs, so that only low extraction forces and low overtorques are achieved.

Die DE 296 03 707 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 describes a metal facade, in particular for conservatories, in which the glass panes are installed in this way should be ensured that the pane is not stretched and tends to break. Therefore, the weight of the glass panes or metal plates used should be optimally introduced into the metal facade. For this purpose, it is intended that one or more glass supports are provided on the fastening channel, which support the glass panes. The weight of the glass panes can be introduced into the metal facade via the glass supports. There is the possibility of connecting the glass supports to the fastening channels by means of screws or the like, but on the other hand it is also suggested that the glass supports be welded to the spars so that the weight absorbed by the glass supports can be transferred to the spars.

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.From DE 94 11 552 U1 a facade with several spars is known, each of which has a U-shaped screw channel. This can be made of aluminum and can be accommodated in a steel receiving channel formed on the spar and welded to it. The problem arises here that such a screw channel made of aluminum has a comparatively low strength and has to be additionally reinforced, for example, by the receiving channel made of steel. Furthermore, aluminum melts at significantly lower temperatures than steel, so that a screw channel made of aluminum is disadvantageous from a fire protection point of view. Finally, contact corrosion can occur when an aluminum component is connected to a steel profile. Another disadvantage of the arrangement according to the cited document is that the screw channel is provided as a component to be inserted separately.

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, the screw channel in technology is usually made of a particularly solid material or with a particularly large material accumulation. There is only a line contact between the screw and the screw channel, over which, in addition to the total wind load on the facade panels, even still the load must be absorbed by the facade panels themselves. Therefore, a particularly high-strength material has always been used in the area of the screw channel in the prior art.

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 to provide a facade profile made of steel, which can be designed with as little effort as possible that it meets the requirements both in terms of the stability of the profile and the stability of the screw channel, while at the same time an easy and safe screwing of fastening screws in the screw channel is permitted.

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

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 characterized in that the screw channel is also made of a steel material, preferably stainless steel. Here, the screw channel is provided on a separate component that is directly connected to the supporting profile of the facade profile. This component can already be firmly connected to the support profile during the manufacture of the facade profile, preferably by welding. No components or the like that are to be handled separately are necessary.

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, the use of steel in terms of stability can be exploited by using a separate component for the screw channel that is firmly connected to the support profile. In other words, a stable screw channel can be produced with little material. Due to the combination of a screw channel made of steel with a facade profile made of stainless steel, there is also the advantage that the connection steel-steel, for example by welding can be easily manufactured. Furthermore, there is no fear of impairment 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 welcher 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 has a lower strength than the profile material. The basic idea of the invention is to use, at least for the screw channel, a stainless steel material which is different from the materials usually used for the facade profiles. For the support profile, a comparatively thin-walled, extremely hard austenitic stainless steel can be used in the usual way due to the given requirements with regard to the formability, the detailed contouring and for economic reasons. According to the invention, a softer steel material than the material of the support profile is used for the component provided separately for this purpose, which has the screw channel. This avoids deformation of the screw thread, and this enables sufficient pull-out forces and sufficient overtorque.

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

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.In order to ensure the mentioned properties of the screw channel on the facade profile according to the invention, it is preferred for the stainless steel material of the screw channel that it has a lower initial strength and / or a lower degree of cold rolling and / or a lower degree of work hardening, which can be achieved, for example, by the choice of a suitable alloy . A lower degree of cold rolling can be achieved, for example, by choosing a thicker wall thickness for the area of the screw channel, so that the stainless steel sheet used for forming the screw channel is deformed to a lesser extent during roll forming, and one compared to the usual 1 to 2 mm thick stainless steel sheet sets less solidification. This is also the case for a steel material with a lower initial strength and / or a lower degree of work hardening, which can be achieved by choosing a suitable alloy, so that the measures described can ensure that the fastening screws are screwed in as required. A combination of the aforementioned measures is also 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 purpose, the use of hot-rolled stainless steel for the area of the screw channel is also advantageous, since the deformation of such stainless steel results in a hardening that does not reach a level at which the screwing in of fastening screws and their secure mounting is impaired.

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) is preferred, each with the Support profile are welded. The screw channel can be formed in a simple manner from the materials described with the specified 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 winkel- oder 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.In this case, it has proven to be advantageous for the use of angle profiles or a U-profile to form a plurality of recesses thereon, in each of which a welded connection is formed. As a result, for the design of the screw channel, for example, from two angular or L-shaped profiles, the legs of which are fixed on the support profile, point away from one another, the advantage that the welded connections can be designed such that they act on the other when a force is applied Thighs are loaded with a lower moment. This also applies to recesses in the area of the middle leg of a U-shaped profile, in which the U-shaped profile through the Training welds can be attached, which are loaded with 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 which form the screw channel on the support profile, it has also proven to be advantageous to form a recess in the support profile in which, for example, a U or W profile can be received. Here, a U-profile can be used, for example, in a groove-like recess formed in the support profile and welded to the edge abutting the groove. Furthermore, it is conceivable to provide two free legs on the support profile with a gap between them, into which a U-profile forming the screw channel is inserted, which is connected to the ends of the two free legs by welding. In a similar way, a largely W-shaped profile can be placed on two free legs of the support profile, which results from a U-shaped profile in that each of the two free legs of a U-shaped profile has further legs parallel to the free legs and extend outside of it back to the level of the connecting portion between the two free legs. As a result, two U-profiles formed next to one another and connected to one another by the connecting section are obtained, which are plugged onto two free legs formed on the support profile in such a way that the respective free leg extends between the two legs of the U-profiles described.

Ausführliche Beschreibung bevorzugter Ausführungsbeispiele der ErfindungDetailed description of preferred embodiments of 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 can be seen in the sectional view of the facade profile 10 according to the invention, which consists of the actual support profile 12 and the screw channel 14 formed thereon. As is customary in the prior art, the support profile 12 is roll-formed from a stainless steel sheet, so that there is an overall closed shape. In other words, the support profile 12 shown only partially in the drawing extends into the area below FIG. 1, so that a hollow profile with a square or rectangular cross section is formed overall. Of course, the support profile 12 as open, U-shaped profile, designed as a T or double T profile.

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 on which the plate-shaped facade components are to be fastened in use, a screw channel 14 is formed, which according to the invention is made of a different, softer material than the support profile 12. In the case shown, the screw channel is formed by two strips or strips 16 made of flat material, which are largely perpendicular to the end face. These are fastened in parallel to one another by welds 18 on the end face of the support profile 12, so that a fastening screw can be screwed in between the strips 16 in such a way that their threads come into engagement with the surfaces of the strips 16 facing one another. According to the invention, the material of the strips 16 is sufficiently soft by the measures described above, so that, for example, commercially available fastening screws made of stainless steel, which, if necessary, can additionally be diffusion-hardened, can penetrate with their thread into the material of the strips 16, so that they are secure in the Screw channel are anchored.

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 is formed instead of the two strips 16 by a U-shaped profile 20, which in the exemplary embodiment shown is firmly connected to the support profile 12 on both sides by foot welds 18 on the outside. In this way, a suitable steel material can be selected for the U-profile 20 forming the screw channel 14, regardless of the material of the support profile 12, which does not impair the fixing of the screws.

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.An alternative fastening option for the U-profile 20 is shown in a top view in FIG. 3. In the area of its middle leg 22 (cf. FIG. 2), this has a plurality of recesses 24, which in this case are largely rectangular, viewed in plan view. The As a result, welding spots 18 can be formed in the area of the recesses 24 in the middle leg 22 and do not have to be created on the outside of the U-profile 20, as is the case in the exemplary embodiment in FIG. 2. This results in a lower load on these connection points due to the lower lever arm acting at the connection points in the form of the welds 18. Of course, the welds 18 can be carried out at any edges of the recesses 24 which extend through to the front surface of the support profile.

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 shows a further embodiment of the facade profile 10 according to the invention, in which the screw channel 14 is formed by two angle profiles 26, which are largely L-shaped. These two angle profiles 26 are arranged mirror-symmetrically to one another, so that respective first legs are spaced apart from one another and extend parallel to one another and form the screw channel 14. The respective second legs extend away from each other and are attached to the support profile 12 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 shows an alternative type of attachment to the support profile 12 for such an embodiment with two angle profiles 26. Similar to the U-profile 20 shown in FIG. 3, the angle profiles 26 have a plurality of recesses 24 which are designed as incisions on the legs of the angle profiles 26 pointing away from one another. Because the welding spots 18 with the support profile 12 can be formed closer to the screw channel 14 at the recesses 24, this modification can also achieve that the fastening points in the form of the welding spots 18 are loaded by lower moments. At the same time, the areas remaining between the recesses 24 ensure sufficient stability against the outward pivoting of the angle profiles 26 when the Fixing screws in the screw channel 14 formed between the profiles 26.

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, by way of example for a U-profile 20, a possibility of how measures for a precise positioning of the components forming the screw channel 14 can be achieved on the support profile 12. Here, the support profile 12 is provided on its end face with a groove-shaped or channel-shaped depression 28 which has flanks which run largely perpendicular to the end face and can be easily formed during the roll forming of the support profile 12. In this recess 28, the U-profile 20 made of a suitable other material can be inserted with a precise fit and connected to the supporting profile 12 by welds 18.

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 U-profile 20 forming the screw channel 14. In this case, the support profile 12 is not designed as a closed hollow profile, but is provided on its end face with an opening through two free, largely perpendicular to Front leg 30 is limited. The U-profile 20 is inserted into the gap or the space between these legs 30 and connected to the support profile 12 by welds 18. Advantageously, the weld seams 18 are provided in contact with the free ends of the legs 30 and against the respective outside of the legs of the U-profile 20. Of course, it is conceivable that the legs 30 are made shorter, so that they are connected to the legs of the U-profile 20 at a point along the longitudinal extent of the legs 20 similar to the embodiment of FIG. 6.

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.FIG. 8 shows a further embodiment of the facade profile 10, in which a largely W-shaped profile is used to form the screw channel 14, the W profile 32 appearing as an inverted W as shown in FIG. 8. 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 are provided outside the two legs and parallel to these further legs 34, which together with the free legs of the U-profile, from which was thought to define an intermediate space into which the respective leg 30 of the support profile 12 extends. In the case shown, the W profile 32 is fastened by welding at the ends of the two legs 34. In this embodiment, the profile 32 forming the screw channel 14 is not only in a lateral direction with respect to the support profile 12 (ie from left to right) 8, but also in the depth direction, ie from top to bottom according to FIG. 8). When choosing a suitable material for the profile 32, despite the comparatively extensive deformation of this profile, as for the screw channel profiles described above, it can be ensured that it remains sufficiently soft to allow the fastening screws to be screwed in satisfactorily. Alternatively, the profile 32 can also be thermoformed so that the strength existing before the deformation is restored.
