Definitions

  • the invention relates to a T-connection between a mullion and a transom profile, in particular for mullion-transom constructions of facades, skylights and winter gardens, according to the preamble of claim 1.
  • the invention also relates to a mullion-transom construction in which mullion and transom profiles arranged at right angles to one another are connected to one another by a T-connection.
  • Such a T-connection is from the DE 299 24 713 U1 known.
  • a connector is attached to an anchoring profile running inside the transom profile, which consists of a shaped body and a collar bolt that is slidably mounted in a holder of the shaped body for engagement in a receiving opening on a side wall of the post profile facing the transom profile.
  • the collar bolt which is used for correct positioning, is slidably mounted within the receiving opening of the shaped body and is pressed into an outwardly displaced assembly position by a compression spring.
  • the collar bolts In order for the transom profile to be inserted between two fixed post profiles, the collar bolts must be pressed back by hand against the force of the compression spring and, after positioning in the desired assembly position, they engage in a hole provided for this purpose on the post profile. For axial securing, the collar bolts have offset locking recesses for positive engagement in the hole of the post profile. However, in order to be able to absorb all loads, an additional load transfer in the form of a screw connection is provided. For this purpose, the transom profile is notched at the front and contains a projection that overlaps the post profile. The transom profile is screwed to the post profile using holes in the projection and corresponding screws. However, this involves a corresponding amount of manufacturing and assembly work. In addition, the collar bolt is no longer accessible from the outside after assembly, so that the connection between the post and transom profile can no longer be easily removed.
  • the object of the invention is to provide a T-connection of the type mentioned at the outset and a mullion-transom construction with such a T-connection, which enable a simplified load-bearing connection of mullion and transom profiles.
  • the load transfer device is designed as an insertion profile that is fixedly arranged on the connecting element and extends along an outer side surface of the connecting element for positive engagement in a transverse groove of the post profile.
  • the T-connection according to the invention allows a transom profile to be easily inserted between two fixed post profiles without complex notches or other time-consuming manufacturing measures and connected to a post profile in a way that is secured against all loads in order to achieve optimal load transfer.
  • the connection can be easily made and, if necessary, released again without damage.

Description

Die Erfindung betrifft eine T-Verbindung zwischen einem Pfosten- und einem Riegelprofil, insbesondere für Pfosten-Riegel-Konstruktionen von Fassaden, Lichtdächern und Wintergärten, nach dem Oberbegriff des Anspruchs 1. Die Erfindung betrifft außerdem eine Pfosten-Riegel-Konstruktion, bei der rechtwinklig zueinander angeordnete Pfosten- und Riegelprofile durch eine T-Verbindung miteinander verbunden sind.The invention relates to a T-connection between a mullion and a transom profile, in particular for mullion-transom constructions of facades, skylights and winter gardens, according to the preamble of claim 1. The invention also relates to a mullion-transom construction in which mullion and transom profiles arranged at right angles to one another are connected to one another by a T-connection.

Eine derartige T-Verbindung ist aus der DE 299 24 713 U1 bekannt. Dort ist auf ein im Inneren des Riegelprofils verlaufendes Verankerungsprofil ein Verbinder aufgesteckt, der aus einem Formkörper und einem in einer Aufnahme des Formkörpers verschiebbar gelagerten Bundbolzen zum Eingriff in eine Aufnahmeöffnung an einer dem Riegelprofil zugewandten Seitenwand des Pfostenprofils besteht. Der zur ordnungsgemäßen Positionierung dienende Bundbolzen ist innerhalb der Aufnahmeöffnung des Formkörpers gleitend gelagert und wird durch eine Druckfeder in eine nach außen verschobene Montagestellung gedrückt. Damit das Riegelprofil zwischen zwei feststehende Pfostenprofile eingesetzt werden kann, müssen die Bundbolzen von Hand entgegen der Kraft der Druckfeder zurückgedrückt werden und rasten nach der Positionierung an der gewünschten Montagestellung in eine dafür vorgesehene Bohrung an dem Pfostenprofil ein. Zur axialen Sicherung weisen die Bundbolzen versetzte Rastausnehmungen zum formschlüssigen Eingriff in die Bohrung des Pfostenprofils auf. Um jedoch sämtliche Belastungen aufnehmen zu können, ist eine zusätzliche Lastabtragung in Form einer Verschraubung vorgesehen. Hierzu ist das Riegelprofil stirnseitig ausgeklinkt und enthält einen das Pfostenprofil überlappenden Überstand. Durch Bohrungen in dem Überstand und entsprechende Schrauben wird das Riegelprofil mit dem Pfostenprofil verschraubt. Dies ist jedoch mit einem entsprechenden Fertigungs- und Montageaufwand verbunden. Außerdem ist der Bundbolzen nach der Montage von außen nicht mehr zugängig, so dass die Verbindung zwischen dem Pfosten- und Riegelprofil nicht mehr ohne weiteres gelöst werden kann.Such a T-connection is from the DE 299 24 713 U1 known. There, a connector is attached to an anchoring profile running inside the transom profile, which consists of a shaped body and a collar bolt that is slidably mounted in a holder of the shaped body for engagement in a receiving opening on a side wall of the post profile facing the transom profile. The collar bolt, which is used for correct positioning, is slidably mounted within the receiving opening of the shaped body and is pressed into an outwardly displaced assembly position by a compression spring. In order for the transom profile to be inserted between two fixed post profiles, the collar bolts must be pressed back by hand against the force of the compression spring and, after positioning in the desired assembly position, they engage in a hole provided for this purpose on the post profile. For axial securing, the collar bolts have offset locking recesses for positive engagement in the hole of the post profile. However, in order to be able to absorb all loads, an additional load transfer in the form of a screw connection is provided. For this purpose, the transom profile is notched at the front and contains a projection that overlaps the post profile. The transom profile is screwed to the post profile using holes in the projection and corresponding screws. However, this involves a corresponding amount of manufacturing and assembly work. In addition, the collar bolt is no longer accessible from the outside after assembly, so that the connection between the post and transom profile can no longer be easily removed.

Die EP 0 496 187 A1 und die DE 198 49 152 A1 offenbaren jeweils den Oberbegriff des Anspruchs 1.The EP 0 496 187 A1 and the DE 198 49 152 A1 each disclose the preamble of claim 1.

Aufgabe der Erfindung ist es, eine T-Verbindung der eingangs genannten Art und eine Pfosten-Riegel-Konstruktion mit einer solchen T-Verbindung zu schaffen, die eine vereinfachte lasttragende Verbindung von Pfosten- und Riegelprofilen ermöglichen.The object of the invention is to provide a T-connection of the type mentioned at the outset and a mullion-transom construction with such a T-connection, which enable a simplified load-bearing connection of mullion and transom profiles.

Diese Aufgabe wird durch eine T-Verbindung mit den Merkmalen des Anspruchs 1 und durch eine Pfosten-Riegel-Konstruktion mit den Merkmalen des Anspruchs 11 gelöst. Zweckmäßige Weiterbildungen und vorteilhafte Ausführungsformen der Erfindung sind Gegenstand der Unteransprüche.This object is achieved by a T-connection with the features of claim 1 and by a post-and-beam construction with the features of claim 11. Appropriate further developments and advantageous embodiments of the invention are the subject of the subclaims.

Bei der erfindungsgemäßen T-Verbindung ist die Lastabtrageinrichtung als ein am Verbindungselement fest angeordnetes und sich entlang einer äußeren Seitenfläche des Verbindungselements erstreckendes Einschubprofil zum formschlüssigen Eingriff in eine Quernut des Pfostenprofils ausgebildet. Durch die erfindungsgemäße T-Verbindung kann ein Riegelprofil auch ohne aufwändige Ausklinkungen oder andere zeitintensive Fertigungsmaßnahmen einfach zwischen zwei feststehende Pfostenprofile eingeschoben und gegen sämtliche Belastungen zur Erreichung einer optimalen Lastabtragung gesichert mit einem Pfostenprofil verbunden werden. Die Verbindung kann einfach hergestellt und bei Bedarf auch ohne Beschädigungen wieder gelöst werden.In the T-connection according to the invention, the load transfer device is designed as an insertion profile that is fixedly arranged on the connecting element and extends along an outer side surface of the connecting element for positive engagement in a transverse groove of the post profile. The T-connection according to the invention allows a transom profile to be easily inserted between two fixed post profiles without complex notches or other time-consuming manufacturing measures and connected to a post profile in a way that is secured against all loads in order to achieve optimal load transfer. The connection can be easily made and, if necessary, released again without damage.

In einer besonders zweckmäßigen Ausführung verläuft das Einschubprofil parallel zu einer Längsachse des Verbindungselements. Dadurch kann ein Riegelprofil auf einfache Weise horizontal zwischen zwei vertikale Pfostenprofile eingesetzt und bei Bedarf auch einfach wieder demontiert werden.In a particularly practical design, the insertion profile runs parallel to a longitudinal axis of the connecting element. This means that a transom profile can be easily inserted horizontally between two vertical post profiles and can also be easily removed again if necessary.

Eine besonders gute Lastabtragung kann z.B. dadurch erreicht werden, dass das Einschubprofil steg- oder leistenförmig ausgebildet ist und einen beispielsweise T-förmigen Querschnitt zum formschlüssigen Eingriff in eine entsprechend T-förmig ausgebildete Quernut des Pfostenprofils aufweist. Dadurch kann das Riegelprofil nicht nur gegen Zugbelastungen, sondern auch gegen Quer- und Torsionsbelastungen gesichert mit dem Pfostenprofil verbunden werden.A particularly good load transfer can be achieved, for example, if the insertion profile is designed in the form of a web or strip and has, for example, a T-shaped cross section for positive engagement in a correspondingly T-shaped transverse groove in the post profile. This means that the transom profile can be connected to the post profile in a way that is not only protected against tensile loads, but also against transverse and torsional loads.

In einer besonders bevorzugten Ausgestaltung ist die Quernut eine zur Außenseite des Pfostenprofils hin offene T-Nut, die sich von der äußeren Stirnwand des Pfostenprofils entsprechend der Länge des Einschubprofils entlang der zum Riegelprofil gewandten Seitenwand des Pfostenprofils erstreckt.In a particularly preferred embodiment, the transverse groove is a T-groove that is open towards the outside of the post profile and extends from the outer end wall of the post profile according to the length of the insertion profile along the side wall of the post profile facing the transom profile.

Das Einschubprofil ist vorzugsweise an dem zu einer äußeren Stirnwand des Riegelprofils gewandten Ende des Verbindungselements angeordnet. Dadurch kann das Riegelprofil von der Vorderseite her zwischen zwei feststehenden Pfostenprofilen eingeschoben werden. Das Einschubprofil kann in einer bevorzugten Ausführung als Profilkörper z.B. aus einem Hohl- oder Vollprofil ausgebildet sein.The insertion profile is preferably arranged at the end of the connecting element facing an outer end wall of the locking profile. This allows the locking profile to be inserted from the front between two fixed post profiles. In a preferred embodiment, the insertion profile can be designed as a profile body, e.g. from a hollow or solid profile.

Zur Positionierung und Lagesicherung des Riegelprofils in einer vorgegebenen Montagestellung kann an dem Verbindungselement in einer weiteren vorteilhaften Ausführung ein z.B. als Rastbolzen zum Eingriff in eine Aufnahmeöffnung des Pfostenprofils ausgebildetes Positionierelement angeordnet sein. Das als Rastbolzen ausgebildete Positionierelement kann auf einem Führungsbolzen verschiebbar geführt und durch eine Druckfeder in eine ausgefahrene Einrückstellung beaufschlagt sein.In order to position and secure the locking profile in a predetermined installation position, a positioning element designed, for example, as a locking bolt for engaging in a receiving opening in the post profile can be arranged on the connecting element in a further advantageous embodiment. The positioning element designed as a locking bolt can be slidably guided on a guide bolt and can be pushed into an extended, engaged position by a compression spring.

Eine erfindungsgemäße Pfosten-Riegel-Konstruktion enthält rechtwinklig miteinander verbundene Pfosten- und Riegelprofile, die durch die vorstehend erläuterte und im Folgenden noch näher beschriebene T-Verbindung miteinander verbunden sind.A mullion-transom construction according to the invention contains mullion and transom profiles connected at right angles to one another, which are connected to one another by the T-connection explained above and described in more detail below.

Das Riegelprofil kann fest oder in Richtung seiner Längsachse beweglich mit dem Verbindungselement verbunden sein. Bei einer beweglichen Verbindung können Längenausdehnungen des Riegelprofils ausgeglichen und dennoch ein stabiler Lastabtrag erreicht werden.The transom profile can be connected to the connecting element either firmly or so that it can move along its longitudinal axis. With a movable connection, longitudinal expansion of the transom profile can be compensated for and stable load transfer can still be achieved.

For positioning and securing the locking profile 2 in a predetermined assembly position, a locking bolt designed as a locking pin is provided on the connecting element 11. Figure 3 recognizable positioning element 16 for engagement in a receiving opening 17 is arranged on the side wall 5 of the post profile 1 facing the locking profile 2. For load transfer, a fixed insertion profile 18 is also provided on the side of the connecting element 11 facing the post profile 1 for positive engagement in a transverse groove 19 open towards the outside in the side wall 5 of the post profile 1 facing the locking profile 2.

In der gezeigten Ausführung ist die Außenkontur des als Hohlprofilkörper ausgebildeten Verbindungselements 11 an die Innenkontur des Hohlraums 3 des Riegelprofils 2 angepasst.

Wie aus Figur 2 hervorgeht, wird das hier als Profilkörper aus einem Hohlprofil ausgebildete Verbindungselement 11 am Ende der Riegelprofils 2 in Richtung der Längsachse 24 des Riegelprofils 2 so in dessen Hohlraum 3 eingesteckt, dass die äußere Seitenfläche 15 des Verbindungselements 11 bündig mit der dem Pfostenprofil 1 zugewandten Stirnfläche 25 des Riegelprofils 2 abschließt und das Einschubteil 18 gegenüber dem Riegelprofil 2 vorsteht.As from Figure 2 As can be seen, the connecting element 11, which is designed here as a profile body made of a hollow profile, is inserted at the end of the transom profile 2 in the direction of the longitudinal axis 24 of the transom profile 2 into the cavity 3 thereof in such a way that the outer side surface 15 of the connecting element 11 is flush with the end surface 25 of the transom profile 2 facing the post profile 1 and the insertion part 18 protrudes relative to the transom profile 2.

Anschließend wird das Verbindungselement 11 über Schrauben 26, Stifte oder andere geeignete Befestigungselemente fest mit dem Riegelprofil 2 verbunden. Hierzu weist das Riegelprofil 2 in den Aufnahmenuten 10 angeordnete Bohrungen 27 und das Verbindungselement 11 an der Außenseite angeordnete Schraubkanäle 28 auf.The connecting element 11 is then firmly connected to the locking profile 2 using screws 26, pins or other suitable fastening elements. For this purpose, the locking profile 2 has holes 27 arranged in the receiving grooves 10 and the connecting element 11 has screw channels 28 arranged on the outside.

Bei der gezeigten Ausführung ist das Einschubprofil 18 in Form eines T-Nutensteins mit einem T-förmigen Querschnitt ausgeführt. Das Einschubprofil 18 ist einstückig mit dem Verbindungselement 11 ausgeführt bzw. an diesem angeformt. Das Einschubprofil 18 könnte aber auch an das Verbindungselement 11 angeschraubt oder auf andere Weise fest mit diesem verbunden sein. Auch die im Pfostenprofil 1 quer zu dessen Längsachse verlaufende Quernut 19 ist als T-Nut mit einer an die Außenkontur des Einschubprofils 18 angepassten Innenkontur ausgeführt.In the embodiment shown, the insertion profile 18 is designed in the form of a T-slot nut with a T-shaped cross-section. The insertion profile 18 is designed as one piece with the connecting element 11 or is molded onto it. The insertion profile 18 could also be screwed onto the connecting element 11 or be firmly connected to it in another way. The transverse groove 19 running in the post profile 1 transversely to its longitudinal axis is also designed as a T-slot with an inner contour adapted to the outer contour of the insertion profile 18.

Aus der Figur 1 geht hervor, dass sich die zur Außenseite des Pfostenprofils 1 hin offene Quernut 19 von der äußeren Stirnwand 7 des Pfostenprofils 1 entsprechend der Länge des Einschubprofils 18 entlang der zum Riegelprofil 2 gewandten Seitenwand 5 des Pfostenprofils 1 erstreckt. Die auf der Höhe der Quernut 19 in der Seitenwand 5 angeordnete Aufnahmeöffnung 17 ist dagegen im Bereich der inneren Stirnwand 6 angeordnet, sodass das Riegelprofil 2 im vorderen und hinteren Bereich des Pfostenprofils 1 abgestützt ist. Das Einschubprofil 18 ist an dem zur äußeren Stirnwand 7 gewandten Ende des Verbindungselement 11 angeordnet, während das als Rastbolzen ausgebildete Positionierelement 16 im Bereich des zur inneren Stirnwand 6 des Riegelprofils 2 weisenden Endes des Verbindungselements 11 angeordnet ist. Dadurch kann das Riegelprofil 2 von der Vorderseite her zwischen zwei feststehende Pfostenprofile 1 eingeschoben werden. Bei einer rückseitigen Montage könnte die Quernut 19 auch in der inneren Stirnwand 6 und die Aufnahmeöffnung 17 im Bereich der äußeren Stirnwand 7 des Pfostenprofils 1 angeordnet sein.From the Figure 1 it can be seen that the transverse groove 19, which is open towards the outside of the post profile 1, extends from the outer end wall 7 of the post profile 1 along the side wall 5 of the post profile 1 facing the locking profile 2 in accordance with the length of the insertion profile 18. The receiving opening 17 arranged at the height of the transverse groove 19 in the side wall 5, on the other hand, is arranged in the area of the inner end wall 6, so that the locking profile 2 is supported in the front and rear areas of the post profile 1. The insertion profile 18 is arranged at the end of the connecting element 11 facing the outer end wall 7, while the positioning element 16 designed as a locking bolt is arranged in the area of the end of the connecting element 11 facing the inner end wall 6 of the locking profile 2. This allows the locking profile 2 to be inserted from the front between two fixed post profiles 1. In the case of rear mounting, the transverse groove 19 could also be arranged in the inner end wall 6 and the receiving opening 17 in the area of the outer end wall 7 of the post profile 1.

In Figur 2 ist erkennbar, dass die innere Nutbreite der T-förmigen Quernut 19 an die Breite des darin angeordneten inneren Teils des T-förmigen Einschubprofils 18 angepasst ist. Dadurch können vertikale Querkräfte und Torsionsbelastungen zwischen dem Riegelprofil und den Postenprofilen abgetragen werden. Gegen horizontale Querkräfte kann die Verbindung zwischen dem Pfosten- und Riegelprofil durch zusätzliche Schrauben 30 gesichert werden. Hierzu ist zwischen dem inneren Teil des T-förmigen Einschubprofils 18 und dem inneren Teil der Quernut 19 ein in Figur 2 erkennbarer Zwischenraum 31 vorgesehen, in den die Schrauben 30 eingedreht werden können. Dadurch ist sowohl eine Verspannung in Zugrichtung als auch eine Sicherung gegen horizontale Querkräfte erreichbar.In Figure 2 It can be seen that the inner groove width of the T-shaped transverse groove 19 is adapted to the width of the inner part of the T-shaped insertion profile 18 arranged therein. This allows vertical transverse forces and torsional loads between the locking profile and the post profiles to be transferred. The The connection between the post and beam profile must be secured by additional screws 30. For this purpose, a screw 30 is provided between the inner part of the T-shaped insertion profile 18 and the inner part of the transverse groove 19. Figure 2 A recognizable gap 31 is provided into which the screws 30 can be screwed. This allows both bracing in the pulling direction and protection against horizontal transverse forces to be achieved.

Zur Montage eines Riegelprofils 2 zwischen zwei feststehenden Pfostenprofilen 1 kann das mit zwei Verbindungselementen 11 endseitig bestückte Riegelprofil 2 von der Vorderseite her mit eingedrückten Positionierelementen 16 horizontal zwischen den Pfostenprofilen 1 eingeschoben werden, so dass zunächst die Einschubprofile 18 in Eingriff mit den Quernuten 19 gelangen und durch weitere Verschiebung die als Rastbolzen ausgeführten Positionselemente 16 in die Aufnahmeöffnungen 17 einrasten. Dadurch wird eine sowohl gegen Verdrehung als auch gegen horizontale und vertikale Verschiebung des Riegelprofils gesicherte Verbindung mit einer optimierten Lastabtragung erreicht. Durch die zusätzlichen Schrauben 30 oder andere geeignete Befestigungselemente kann die Verbindung auch noch verspannt werden.To install a locking profile 2 between two fixed post profiles 1, the locking profile 2, which is fitted with two connecting elements 11 at the end, can be inserted horizontally between the post profiles 1 from the front with the positioning elements 16 pressed in, so that the insertion profiles 18 first engage with the transverse grooves 19 and, by further displacement, the positioning elements 16 designed as locking bolts snap into the receiving openings 17. This creates a connection that is secured against both twisting and horizontal and vertical displacement of the locking profile with optimized load transfer. The connection can also be tightened using the additional screws 30 or other suitable fastening elements.
