Description

Die Erfindung betrifft ein Stahl-Tragprofil für Tragkonstruktionen von Fassaden und Wintergärten nach dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine Tragkonstruktion mit einem derartigen Stahl-Tragprofil.The invention relates to a steel support profile for supporting structures of facades and conservatories according to the preamble of claim 1. The invention also relates to a support structure with such a steel support profile.

Ein derartiges Stahl-Tragprofil ist aus der DE 295 00286 U1 bekannt. Dort ist das Tragprofil einteilig aus einem gebogenen und an der Nahtstelle verschweißten Stahlblech hergestellt und weist an einer nach außen weisenden Querseite einen in das Tragprofil integrierten, nach außen offenen Schraubkanal für Befestigungsschrauben auf. Nachteilig bei dieser Ausführung ist, dass das Tragprofil nur in einer einheitlichen Wandstärke hergestellt werden kann. Da übliche Schraubkanalprofile nur bis zu einer maximalen Wandstärke von ca. 1,5 mm hergestellt werden können, sind auch die Wandstärke und die Gestaltungsmöglichkeiten des übrigen Profils beschränkt.Such a steel support profile is from the DE 295 00286 U1 known. There, the support profile is made in one piece from a bent and welded at the seam steel sheet and has on an outwardly facing transverse side integrated in the support profile, outwardly open screw channel for mounting screws. A disadvantage of this design is that the support profile can be made only in a uniform wall thickness. Since conventional screw channel profiles can only be made up to a maximum wall thickness of about 1.5 mm, the wall thickness and the design options of the rest of the profile are limited.

Aufgabe der Erfindung ist es, ein einfach herstellbares Stahl-Tragprofil und eine Tragkonstruktion mit einem derartigen Stahl-Tragprofil zu schaffen, die größere Gestaltungsmöglichkeiten erlauben.The object of the invention is to provide a simple to produce steel support section and a support structure with such a steel support profile, which allow greater design options.

Diese Aufgabe wird durch ein Stahl-Tragprofil mit den Merkmalen des Anspruchs 1 und durch eine Tragkonstruktion mit den Merkmalen des Anspruchs 12 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a steel support profile with the features of claim 1 and by a support structure with the features of claim 12. Advantageous developments and advantageous embodiments of the invention are the subject of the dependent claims.

Das erfindungsgemäße Stahl-Tragprofil besteht aus mindestens zwei Teilen und enthält eine nach außen weisende und mit einem integrierten Aufnahmekanal für Befestigungsschrauben versehene Seitenwand, die mit einem vorzugsweise kastenförmigen Grundprofil verschweißt ist. Dadurch kann das Stahl-Tragprofil relativ einfach an die unterschiedlichsten Anforderungen angepasst werden. Mit geeigneten Schweißverfahren, z.B. Laserschweißen oder MAG kann die mit dem Aufnahmekanal für die Befestigungsschrauben versehene Seitenwand mit dem Grundprofil zu einem vorzugsweise kastenförmigen Hohlprofil verschweißt werden. Die Längsseiten können zur Verbesserung der Statik und zur Erfüllung der gestalterischen Anforderungen in unterschiedlichen Wandstärken und Querschnitten ausgeführt werden. So können z.B. auch scharfkantige Tragprofile mit integriertem Schraubkanal auf einfache und kostengünstige Weise hergestellt werden.The steel support profile according to the invention consists of at least two parts and contains an outwardly facing and provided with an integrated receiving channel for mounting screws side wall, which is welded to a preferably box-shaped base profile. As a result, the steel support profile can be relatively easily adapted to a wide variety of requirements. With suitable welding methods, such as laser welding or MAG, the side wall provided with the receiving channel for the fastening screws with the base profile to a preferably box-shaped hollow profile be welded. The long sides can be designed to improve the statics and to meet the design requirements in different wall thicknesses and cross sections. For example, even sharp-edged support profiles with integrated screw can be made in a simple and cost-effective manner.

In einer fertigungstechnisch einfachen und kostengünstigen Ausführung kann die Seitenwand mit dem integrierten Aufnahmekanal einteilig aus einem gebogenen Stahlblech hergestellt sein.In a manufacturing technology simple and cost-effective design, the side wall with the integrated receiving channel can be made in one piece from a bent sheet steel.

Das Grundprofil ist vorzugsweise als einseitig offenes Hohlprofil ausgebildet und enthält zweckmäßigerweise zwei voneinander Längsseiten, zwischen die die Seitenwand eingesetzt ist.The base profile is preferably designed as a hollow profile open on one side and expediently contains two longitudinal sides, between which the side wall is inserted.

Zur sicheren Befestigung der Seitenwand an dem Grundprofil kann die Seitenwand zwei umgebogene Enden enthalten, die zur Anlage an der Innenseite der beiden Längsseiten des Grundprofils gelangen.For secure attachment of the side wall to the base profile, the side wall may contain two bent ends, which come to rest on the inside of the two longitudinal sides of the base profile.

In einer besonders zweckmäßigen Ausführung ist an dem Übergang zwischen der Seitenwand und dem Grundprofil eine Hohlkehle zum Einbringen einer Schweißnaht gebildet. Dadurch kann die Schweißnaht an einer von außen unsichtbaren Stelle angebracht werden.In a particularly advantageous embodiment, a groove for introducing a weld is formed at the transition between the side wall and the base profile. This allows the weld to be attached to a location invisible from the outside.

Gemäß einer weiteren vorteilhaften Ausführung ist in den Aufnahmekanal des Tragprofils ein Zwischenprofil zur Halterung einer Innendichtung eingesteckt. Durch dieses Zwischenprofil wird die Innendichtung stabilisiert und fixiert. Das Zwischenprofil übernimmt aber keinerlei Haltefunktion für die Fassadenelemente. Die Fassadenelemente werden durch das Halteprofil über Befestigungsschrauben fixiert, die direkt in das Tagprofil eingeschraubt sind. Die Befestigungsschrauben sind unmittelbar am Tragprofil und nicht an dem Zwischenprofil befestigt. Dadurch kann eine stabile Halterung der Fassadenelemente und eine sichere Halterung der Innendichtung erreicht werden.According to a further advantageous embodiment, an intermediate profile for holding an inner seal is inserted into the receiving channel of the support profile. Through this intermediate profile, the inner seal is stabilized and fixed. However, the intermediate profile does not assume any holding function for the facade elements. The façade elements are fixed by the retaining profile via fastening screws, which are screwed directly into the tag profile. The mounting screws are attached directly to the support profile and not to the intermediate profile. This allows a stable mounting of the facade elements and a secure mounting of the inner seal can be achieved.

In einer besonders zweckmäßigen Ausführung ist das Zwischenprofil aus Kunststoff, vorzugsweise Hartkunststoff, hergestellt. Dies hat den Vorteil, dass keine metallisch leitenden Teile ach außen in den Dichtungsbereich hinein ragen und so die Wärmedämmung erheblich verbessert wird. Ein weitere Vorteil liegt darin, dass die Dichtung mit dem Kunststoff-Zwischenstück exakt geführt und gehalten werden kann, was in einem Stahlprofil nur sehr aufwändig realisiert werden kann. Das Zwischenprofil kann aber auch aus Aluminium oder einem anderen geeigneten Material bestehen.In a particularly advantageous embodiment, the intermediate profile is made of plastic, preferably hard plastic. This has the advantage that no metallic conductive parts project into the outside of the sealing area and so the thermal insulation is significantly improved. Another advantage is that the seal with the plastic spacer can be exactly guided and maintained, which can be realized in a steel profile only very expensive. The intermediate profile may also consist of aluminum or another suitable material.

Das Zwischenprofil ist in vorteilhafter Weise über eine Clipverbindung in den Aufnahmekanal des Stahl-Tragprofil eingesetzt. Es kann z.B. ein Einsteckteil zum Einstecken in das Tragprofil aufweisen. Dadurch kann das Zwischenprofil z.B. auf einfache Weise in den Aufnahmekanal des Tragprofils eingesteckt und somit schnell und einfach montiert werden. In einer möglichen Ausgestaltung kann das Einsteckteil des Zwischenprofils z.B. zwei flexible Halteschenkel enthalten.The intermediate profile is used in an advantageous manner via a clip connection in the receiving channel of the steel support profile. It can e.g. have a plug-in part for insertion into the support profile. As a result, the intermediate profile, e.g. be easily inserted into the receiving channel of the support profile and thus quickly and easily mounted. In one possible embodiment, the insertion part of the intermediate profile may be e.g. contain two flexible retaining legs.

In einer weiteren zweckmäßigen Ausgestaltung kann das Zwischenprofil auch ein Führungsteil zur Führung der Befestigungsschrauben aufweisen. Dadurch kann das Einschrauben der Befestigungsschrauben in das Tragprofil erleichtert werden. Das Führungsteil kann z.B. als Führungskanal ausgebildet sein.In a further expedient embodiment, the intermediate profile may also have a guide part for guiding the fastening screws. As a result, the screwing of the fastening screws can be facilitated in the support profile. The guide part may e.g. be designed as a guide channel.

An dem Zwischenprofil sind vorzugsweise Halteelemente zur Fixierung der Innendichtung vorgesehen. Die Halteelemente können z.B. in Form von Haltenasen zum Eingriff in entsprechende Haltenuten der Innendichtung ausgebildet sein. Die Halteelemente können auch als Nuten und die entsprechenden Gegenelemente an der Innendichtung als Vorsprünge oder dgl. ausgebildet sein. Auch andere Halteprofilierungen sind denkbar.At the intermediate profile holding elements are preferably provided for fixing the inner seal. The holding elements may e.g. be formed in the form of retaining lugs for engagement in corresponding retaining grooves of the inner seal. The holding elements may also be formed as grooves and the corresponding counter-elements on the inner seal as projections or the like. Other retaining profiles are conceivable.

Die Erfindung betrifft außerdem eine Tragkonstruktion für Fassaden und Wintergärten, bei der die Tragprofile in der vorstehend beschriebenen Weise ausgeführt sind.The invention also relates to a supporting structure for facades and conservatories, in which the support profiles are designed in the manner described above.

Durch die umgebogenen Enden 12 wird am Übergang zu den Längswänden 10 des Grundprofils 9 eine Hohlkehle 13 zum Einbringen einer als Kehlnaht ausgeführten Schweißnaht 11 gebildet. Dadurch sind die Schweißnähte 11 von außen nicht sichtbar.Trained as a hollow profile steel support section 1 is in the in FIG. 1 illustrated embodiment of two parts of a base profile 9 and welded to the base profile 9 transverse wall 7. The base profile 9 includes two mutually parallel and spaced-apart longitudinal walls 10, between which the transverse wall 7 made of a bent sheet steel is inserted and welded to the base profile 9 via welds 11. The side wall 7 is bent in such a way that, in addition to the receiving channel 8 designed as a screw channel and integrated into the transverse wall 7, it contains two bent ends 12 for engagement with the inside of the two longitudinal walls 10. By the bent ends 12, a groove 13 is formed at the transition to the longitudinal walls 10 of the base profile 9 for introducing a fillet weld 11 designed as a fillet weld. As a result, the welds 11 are not visible from the outside.

Der nach außen offene Aufnahmekanal 8 an der den Fassadenelementen 2a und 2b zugewandten Querwand 7 des Tragprofils 1 weist einen trapezförmigen Querschnitt auf. In den Aufnahmekanal 8 des Tragprofils 1 werden die zweckmäßigerweise mit einem Schneidgewinde 14 versehenen Befestigungsschrauben 6 eingeschraubt, so dass das Halteprofil 3 zur Halterung der Fassadenelemente 2a und 2b über die Befestigungsschrauben 6 direkt an dem Tragprofil 1 befestigt ist.The outwardly open receiving channel 8 on the facade elements 2a and 2b facing transverse wall 7 of the support section 1 has a trapezoidal cross-section.
