Description

Die Erfindung betrifft eine Befestigungsvorrichtung für Fassadenelemente nach dem Oberbegriff des Anspruchs 1, sowie ein Verfahren zum Befestigen von Fassadenelementen auf Trägerprofilen einer Fassadenkonstruktion.The invention relates to a fastening device for facade elements according to the preamble of claim 1, and a method for fixing facade elements on support profiles of a facade construction.

Derartige Befestigungsvorrichtungen für Fassadenelemente werden in einer Fassadenkonstruktion aus Trägerprofilen benötigt, die beispielsweise aus einer Pfosten/Riegelkonstruktion bestehen. Die Pfosten- und Riegelkonstruktionen können aus Holz aber auch aus Metall bestehen. Besonders bevorzugt sind Stahlhohlprofile und Stahlvollprofile. Es ist bekannt auf den Trägerprofilen Aufsatzprofile aufzusetzen, die einen Schraubkanal aufweisen. In den Schraubkanal kann eine Befestigungsschraube eingeschraubt werden, mit deren Hilfe eine Klemmleiste gegen die Fassadenelemente der Fassadenkonstruktion angedrückt werden kann, um die Fassadenelemente auf der Fassadenkonstruktion zu befestigen.Such fastening devices for facade elements are required in a facade construction of support profiles, which consist for example of a post / transom construction. The mullion and transom constructions can be made of wood or metal. Particularly preferred are hollow steel profiles and solid steel profiles. It is known to set up on the support profiles attachment profiles that have a screw. In the screw a fastening screw can be screwed, with the aid of a terminal strip can be pressed against the facade elements of the facade construction to secure the facade elements on the facade construction.

Nachteilig ist bei dem bekannten Stand der Technik, dass der Schraubkanal mit dem Trägerprofil verschweißt ist. Infolgedessen muss der Schraubkanal mit dem Trägerprofil vorgefertigt sein und kann nicht erst auf der Baustelle angebracht werden.A disadvantage of the known prior art that the screw is welded to the carrier profile. As a result, the screw must be prefabricated with the carrier profile and can not be installed on the site.

Die Offenlegungsschrift DE 10025169 A1 beschreibt eine Vorrichtung zur Befestigung eines Fassadenprofils an einem Tragprofil. Dabei werden Haltebolzen durch das Fassadenprofil hindurch in das Tragprofil geschossen. Nachteilig bei diesem Stand der Technik ist, dass eine Verbindung über die Haltebolzen nur schwierig lösbar ist, so dass das Fassadenprofil nur mit großem Aufwand von dem Tragprofil demontierbar ist. Darüberhinaus müssen derartige Haltebolzen relativ tief in das Tragprofil hineingeschossen werden, so dass durch die Verdrängung des Tragprofilmaterials durch den Haltebolzen Spannungen in dem Tragprofil auftreten können, die das Tragprofil schwächen können.The publication DE 10025169 A1 describes a device for fixing a facade profile to a support profile. In this case, retaining bolts are shot through the facade profile into the supporting profile. A disadvantage of this prior art is that a connection on the retaining bolts is difficult to solve, so that the facade profile can be disassembled only with great effort from the support profile. Moreover, such retaining bolts must be shot relatively deep into the support section, so that stresses can occur in the support profile by the displacement of the support profile material by the retaining bolts, which can weaken the support profile.

Der Erfindung liegt daher die Aufgabe zugrunde, ein Aufsatzprofil sowie ein Verfahren zum Befestigen von Fassadenelementen zu schaffen, das in einfacher Weise nachträglich, z.B. auf der Baustelle, mit dem Profilträger verbunden werden kann.The invention is therefore an object of the invention to provide an attachment profile and a method for fixing facade elements, which in a simple manner subsequently, for. on the construction site, can be connected to the profile beam.

Zur Lösung dieser Aufgabe dienen die Merkmale des Anspruchs 1 bzw. 19.To solve this problem serve the features of claim 1 and 19, respectively.

Die Erfindung sieht in vorteilhafter Weise vor, dass die Trägerprofile zum Befestigen des Aufsatzprofils eine aus Löchern bestehende erste Lochreihe aufweisen, und dass die dem Trägerprofil zugewandte Seite des Aufsatzprofiles im Bereich des Schraubkanals eine der ersten Lochreihe hinsichtlich des Lochabstandes angepasste zweite Lochreihe aus Bohrungen aufweist, durch die erste Befestigungsschrauben mit einem Selbstschneidegewinde in die Löcher des Trägerprofils einschraubbar sind. In den Schraubkanal sind zweite Befestigungsschrauben einschraubbar, die die Klemmleiste gegen die Fassadenelemente der Fassadenkonstruktion vorspannen, wodurch die Fassadenelemente in der Fassadenkonstruktion gehalten werden.The invention advantageously provides that the carrier profiles for attaching the attachment profile have a first row of holes consisting of holes, and that the side of the attachment profile facing the carrier profile has, in the region of the screw channel, a second row of holes adapted to the hole spacing with respect to the hole spacing, can be screwed through the first mounting screws with an auto-cutting thread in the holes of the carrier profile. In the screw second fastening screws are screwed, which bias the terminal block against the facade elements of the facade construction, whereby the facade elements are held in the facade construction.

Bei einem bevorzugten Ausführungsbeispiel ist vorgesehen, dass das Aufsatzprofil aus einem ersten Profilteil mit einem im wesentlichen U-förmigen Aufnahmekanal besteht, der eine Aufnahmeeinrichtung für einen werkzeuglos einfügbaren zweiten Profilteil bildet, der den Schraubkanal aufweist.In a preferred embodiment, it is provided that the attachment profile consists of a first profile part with a substantially U-shaped receiving channel, which forms a receiving device for a tool-free insertable second profile part having the screw channel.

Das zweiteilige Aufsatzprofil hat den Vorteil, dass das zweite Profilteil mit dem Schraubkanal werkzeuglos in den Aufnahmekanal einfügbar ist.The two-part attachment profile has the advantage that the second profile part with the screw can be inserted without tools into the receiving channel.

Vorzugsweise ist vorgesehen, dass die Wände des Aufnahmekanals elastisch verformbar sind und mit dem zweiten Profilteil verrastbar sind. Das zweite Profilteil wird nicht in das erste Profilteil seitlich eingeschoben, sondern von oben in den Aufnahmekanal hineingedrückt, wodurch das erste Profilteil mit dem zweiten Profilteil verrastet.It is preferably provided that the walls of the receiving channel are elastically deformable and can be latched to the second profile part. The second profile part is not laterally inserted into the first profile part, but pressed from above into the receiving channel, whereby the first profile part locked to the second profile part.

Das erste Profilteil kann mit nach innen in den Aufnahmekanal vorspringenden Rastnasen versehen sein, die in entsprechender Aussparung des zweiten Profilteils eingreifen, ist ein sicherer Halt des zweiten Profilteils in dem Aufnahmekanal gewährleistet.The first profile part can be provided with inwardly projecting into the receiving channel locking lugs in the corresponding recess of the second profile part engage, a secure hold of the second profile part is ensured in the receiving channel.

Das Aufsatzprofil weist an den inneren Seitenwänden des Schraubkanals längslaufende Nuten im Abstand der Schraubensteigung der zweiten Befestigungsschrauben auf.The attachment profile has, on the inner side walls of the screw channel, longitudinal grooves spaced apart from the helical pitch of the second fastening screws.

Dadurch kann der Eingriff der zweiten Befestigungsschrauben, die auch mit einem Selbstschneidegewinde versehen sein können, verbessert werden, so dass höhere Haltekräfte realisiert werden können.As a result, the engagement of the second fastening screws, which may also be provided with an auto-cutting thread, can be improved, so that higher holding forces can be realized.

Die längslaufenden Nuten auf der einen Seitenwand des Schraubkanals können relativ zu den längslaufenden Nuten auf der anderen Seitenwand des Schraubkanals entsprechend der Steigung der zweiten Befestigungsschrauben versetzt angeordnet sein. Auf diese Weise ist sichergestellt, dass die Befestigungsschrauben beidseitig mit den Nuten im Eingriff sind.The longitudinal grooves on the one side wall of the screw can be arranged offset relative to the longitudinal grooves on the other side wall of the screw corresponding to the pitch of the second fastening screws. In this way it is ensured that the fastening screws are engaged on both sides with the grooves.

Der Schraubkanal kann in etwa in der Mitte seiner Tiefe mit einem quer zu den Seitenwänden verlaufenden Steg verbunden sein, der die Haltekräfte des Schraubkanals erhöht und von der selbstschneidenden Befestigungsschraube durchstoßen werden kann. Der Steg kann vorzugsweise orthogonal zu den Seitenwänden verlaufen.The screw can be connected approximately in the middle of its depth with a transverse to the side walls web, which increases the holding forces of the screw and can be pierced by the self-tapping screw. The web may preferably be orthogonal to the side walls.

Ein Dichtungsprofil überdeckt das Aufsatzprofil vollständig und verschließt den Schraubkanal, so dass keine Feuchtigkeit in den Schraubkanal des Aufsatzprofils eindringen kann.A sealing profile covers the attachment profile completely and closes the screw channel, so that no moisture can penetrate into the screw channel of the attachment profile.

Die Dichtung kann einen in den Schraubkanal hineinragenden Vorsprung aufweisen, mit dessen Hilfe die Dichtung in dem Schraubkanal gehalten wird.The seal may have a protruding into the screw projection, by means of which the seal is held in the screw.

Das erste Profilteil weist vorzugsweise einen Auflageflansch auf, von dem der Aufnahmekanal des ersten Profilteils orthogonal absteht.The first profile part preferably has a support flange from which the receiving channel of the first profile part projects orthogonally.

Der auf einem Trägerprofil aufliegende Auflageflansch des ersten Profilteils oder des Aufsatzprofils kann auf der dem Trägerprofil zugewandten Seite in Längsrichtung des Aufsatzprofils verlaufende Kanäle aufweisen. Das dem Trägerprofil zugewandte Ende des zweiten Profilteils ist im Querschnitt V-förmig zulaufend, so dass dieses Ende des Profilteils leichter in den Aufnahmekanal eingeführt werden kann und die Wände des Aufnahmekanals zum Einfügen des zweiten Profilteils nach außen gedrückt werden, um anschließend mit dem zweiten Profilteil zu verrasten.The resting on a support profile support flange of the first profile part or the attachment profile may have on the carrier profile side facing in the longitudinal direction of the attachment profile extending channels. The carrier profile facing the end of the second profile part is tapered in cross-section V-shaped, so that this end of the profile part can be easily inserted into the receiving channel and the walls of the receiving channel for inserting the second profile part are pressed to the outside, then to the second profile part to lock.

Das erste Profilteil ist mit den ersten selbstschneidenden Befestigungsschrauben in den Sacklöschern des Trägerprofils befestigbar, wobei die Klemmleiste für die Fassadenelemente mit den zweiten Befestigungsschrauben in dem Schraubkanal befestigbar ist.The first profile part can be fastened with the first self-tapping fastening screws in the sack erasers of the carrier profile, wherein the clamping strip for the facade elements with the second fastening screws in the screw is fastened.

Die Trägerprofile bestehen vorzugsweise aus Vollmaterial, wobei die erste Lochreihe aus Sacklöchern in dem Vollmaterial gebildet ist.The carrier profiles are preferably made of solid material, wherein the first row of holes of blind holes is formed in the solid material.

Im folgenden werden unter Bezugnahme auf die Zeichnungen Ausführungsbeispiele der Erfindung näher erläutert.In the following, embodiments of the invention will be explained in more detail with reference to the drawings.

Bekannte Fassadenkonstruktionen bestehen aus Pfostenriegel-Konstruktionen, die aus Trägerprofilen 2 gebildet sind. Vorzugsweise sind die Trägerprofile aus Metall, z.B. aus Aluminium oder Stahl gefertigt. Die Trägerprofile 2 können allerdings auch aus Holz bestehen.Known facade constructions consist of post-bar constructions, which are formed from carrier profiles 2. Preferably, the carrier profiles are made of metal, for example made of aluminum or steel. However, the carrier profiles 2 can also be made of wood.

Bei Stahlprofilen kann das Trägerprofil aus einem Hohlprofil oder aus einem Vollprofil bestehen.For steel profiles, the carrier profile may consist of a hollow profile or of a solid profile.

Im folgenden sind Ausführungsbeispiele gezeigt, bei denen die Trägerprofile 2 aus Vollmaterial bestehen.In the following embodiments are shown in which the carrier profiles 2 are made of solid material.

Die Trägerprofile aus Metall, vorzugsweise aus Stahl, weisen eine Lochreihe aus Sacklöchern 15 auf, die in einem vorbestimmten Abstand angeordnet sind, wobei die Trägerprofile 2 mit vorgefertigten Sacklöchern 15 an eine Baustelle geliefert werden.The support profiles made of metal, preferably made of steel, have a row of holes of blind holes 15 which are arranged at a predetermined distance, the support profiles 2 are supplied with prefabricated blind holes 15 to a construction site.

Die Sacklöcher 15 dienen zur Aufnahme einer Befestigungsvorrichtung für Fassadenelemente 14, beispielsweise Glasscheiben, insbesondere Isolierglasscheiben.The blind holes 15 serve to receive a fastening device for facade elements 14, for example glass panes, in particular insulating glass panes.

Im Falle von Trägerprofilen 2 aus Hohlprofilen sind anstelle der Sacklöcher 15 lediglich Löcher in Form von Bohrungen in dem Trägerprofil vorgesehen.In the case of carrier profiles 2 of hollow profiles 15 holes are provided in the form of holes in the carrier profile instead of the blind holes.

Die Befestigungsvorrichtung besteht aus einem Aufsatzprofil 6, das mit einem Schraubkanal 8 versehen ist, wobei der Schraubkanal 8 eine Befestigungsschraube 11 aufnehmen kann, mit deren Hilfe eine Klemmleiste 12 gegen die Fassadenelemente 14 und diese gegen die Trägerprofile angepresst werden.The fastening device consists of an attachment profile 6, which is provided with a screw 8, wherein the screw 8 can receive a fastening screw 11, by means of which a terminal strip 12 against the facade elements 14 and these are pressed against the carrier profiles.

Zur Montage des Aufsatzprofils 6 auf der Baustelle weist das Aufsatzprofil 6 auf der dem Trägerprofil 2 zugewandten Seite eine Lochreihe aus Bohrungen 18 auf, durch die eine zweite Befestigungsschraube 10 mit einem Selbstschneidegewinde in die Löcher bzw.

Das Aufsatzprofil 6 besteht beispielsweise aus eloxiertem Aluminium und weist auf der Unterseite des Auflageflansches 52 mehrere parallel zu dem Aufsatzprofil 6 verlaufende Kanäle 54 auf, die die Kontaktfläche mit dem Trägerprofil 2 verringern und eine Belüftung zwischen dem Aufsatzprofil 6 und Trägerprofil 2 ermöglichen. Auf der dem Trägerprofil abgewandten Seite des Auflageflansches 2 verlaufen jeweils im Randbereich zwei von dem Auflageflansch 52 abstehende Leisten 7, die mit einer das Aufsatzprofil 6 umschließenden Profildichtung 48 im Eingriff sind. Die Profildichtung 48 verschließt den Schraubkanal 8 und weist zur Verankerung in dem Schraubkanal 8 einen Vorsprung 50 auf.The attachment profile 6 consists for example of anodized aluminum and has on the underside of the support flange 52 a plurality of parallel to the attachment profile 6 extending channels 54, which reduce the contact area with the carrier profile 2 and allow ventilation between the attachment profile 6 and carrier profile 2. On the side facing away from the carrier profile of the support flange 2 extend in each case in the edge region two protruding from the support flange 52 strips 7, which are in engagement with a profile profile 6 enclosing the profile seal 48. The profile seal 48 closes the screw 8 and has for anchoring in the screw 8 a projection 50.

Das einteilige Aufsatzprofil 6 ist im Bereich der Langloch-Bohrungen 18 zur Bildung einer Kopfauflage 9 für die Befestigungsschraube 10 abgefräst, so dass die Köpfe der Befestigungsschrauben 10 wie aus Fig. 1 ersichtlich nicht über die Oberkante des Schraubkanals 8 überstehen.The one-piece attachment profile 6 is milled off in the region of the elongated hole bores 18 to form a head rest 9 for the fastening screw 10, so that the heads of the fastening screws 10, as shown in FIG. 1, do not project beyond the upper edge of the screw channel 8.

In Fig. 2 ist die Kopfauflage 9 in Draufsicht ersichtlich.In Fig. 2, the headrest 9 is visible in plan view.

Zweite Befestigungsschrauben 11 zum Spannen der Klemmleiste 12 gegen die Fassadenelemente 14 können in den Schraubkanal 8 eingeschraubt werden, wobei auch diese Befestigungsschrauben 11 aus selbstschneidenden Befestigungsschrauben bestehen können.Second fixing screws 11 for clamping the terminal block 12 against the facade elements 14 can be screwed into the screw 8, whereby these fastening screws 11 may consist of self-tapping screws.

Zwischen der Klemmleiste 12 und den Fassadenelementen 14 ist eine weitere profilierte Dichtung 49 vorgesehen, die beim Einschrauben der Befestigungsschrauben 11 an den jeweiligen Durchbruchstellen perforiert wird. Die Befestigungsschraube 11 wird desweiteren durch die Profildichtung 48 und den Vorsprung 50 hindurch in den Schraubkanal 8 hineingeschraubt. Der Schraubkanal 8 weist an den im wesentlichen parallel verlaufenden inneren Seitenwänden 34 des Schraubkanals längslaufende Nuten 38 auf, die im Abstand der Schraubensteigung der zweiten Befestigungsschrauben 11 angeordnet sind. Die Nuten der einen Seitenwand des Schraubkanals 8 verlaufen entsprechend der Steigung der zweiten Befestigungsschrauben 11 versetzt zu den Nuten auf der anderen Seitenwand des Schraubkanals. Insofern entspricht der Schraubkanal 8 gemäß dem einteiligen Aufsatzprofil in Fig. 1 dem in Fig. 3 gezeigten Schraubkanal 8.Between the terminal block 12 and the facade elements 14, a further profiled seal 49 is provided, which is perforated when screwing the fastening screws 11 at the respective penetration points. The fastening screw 11 is further screwed through the profile seal 48 and the projection 50 into the screw 8. The screw 8 has at the substantially parallel inner side walls 34 of the screw longitudinal grooves 38, which are arranged at a distance of the helical pitch of the second fastening screws 11. The grooves of one side wall of the screw 8 extend in accordance with the slope of the second fastening screws 11 offset from the grooves on the other side wall of the screw channel. In this respect, the screw 8 according to the one-piece attachment profile in Fig. 1 corresponds to the screw 8 shown in FIG.

Wie aus Fig. 2 in Verbindung mit Fig. 1 hervorgeht, endet der Schraubkanal 8 in einer Tiefe, die oberhalb dem Auflageflansch 52 liegt.As is apparent from Fig. 2 in conjunction with Fig. 1, the screw 8 terminates at a depth which lies above the support flange 52.

Bei diesem Ausführungsbeispiel können die Befestigungsschrauben 11 nicht an den Stellen eingeschraubt werden, an denen sich bereits die ersten Befestigungsschrauben 10 befinden.In this embodiment, the fastening screws 11 can not be screwed into the places where already the first fastening screws 10 are located.

Fig. 3 zeigt ein zweites Ausführungsbeispiel mit einem zweiteiligen Aufsatzteil 6. Das Aufsatzprofil 6 besteht aus einem ersten Profilteil 20 mit dem Auflageflansch 52 und einem orthogonal von dem Auflageflansch 52 abstehenden Aufnahmekanal 24, sowie aus einem zweiten Profilteil 28, das werkzeuglos in den Aufnahmekanal 24 einclipbar ist. Hierzu können die Wände 22 des Aufnahmekanals 24 leicht nach außen gespreizt werden, damit das zweite Profilteil 28 in dem ersten Profilteil 20 einrasten kann. Ein besonderer Vorteil dieser Lösung ist, dass das schienenförmige zweite Profilteil 28 nicht von der Seite in den Aufnahmekanal 24 eingeführt werden muss, sondern auf das erste Profilteil 20 aufgedrückt werden kann, bis die an den freien Enden der Wände 22 angeordneten Rastnasen 30 in entsprechende Aussparungen 32 des zweiten Profilteils 28 einrasten.Fig. 3 shows a second embodiment with a two-part attachment part 6. The attachment profile 6 consists of a first profile part 20 with the support flange 52 and a orthogonal projecting from the support flange 52 receiving channel 24, and a second profile part 28, the tool without in the receiving channel 24th einclipbar is. For this purpose, the walls 22 of the receiving channel 24 can be slightly spread outwards so that the second profile part 28 can engage in the first profile part 20. A particular advantage of this solution is that the rail-shaped second profile part 28 does not have to be inserted from the side into the receiving channel 24, but can be pressed onto the first profile part 20 until the locking lugs 30 arranged at the free ends of the walls 22 engage in corresponding recesses 32 of the second profile part 28 engage.

Das in Fig. 3 gezeigte zweiteilige Aufsatzteil 6 besteht vorzugsweise aus eloxiertem Aluminium, kann aber beispielsweise aus Kunststoff bestehen.The two-part attachment 6 shown in Fig. 3 is preferably made of anodized aluminum, but may for example consist of plastic.

Wie aus Fig. 3 ersichtlich, kann der Schraubkanal 8 durch einen Steg 44 überbrückt sein, der dem zweiten Profilteil 28 eine höhere Steifheit verleiht. Die Befestigungsschraube 11 wird durch diesen Steg 44 hindurch geschraubt, wodurch eine besonders feste Verbindung zwischen der Befestigungsschraube 11 und dem zweiten Profilteil 28 geschaffen wird.As can be seen from FIG. 3, the screw channel 8 can be bridged by a web 44, which gives the second profile part 28 a higher rigidity. The fastening screw 11 is screwed through this web 44, whereby a particularly firm connection between the fastening screw 11 and the second profile part 28 is created.

Der Steg 44 ist vorzugsweise zwischen den Seitenwänden 34,36 in einer mittleren Tiefe angeordnet und verläuft orthogonal zu dem Schraubkanal 8.The web 44 is preferably arranged between the side walls 34, 36 at a medium depth and runs orthogonal to the screw channel 8.

Das dem Aufnahmekanal 24 zugewandte Ende des zweiten Profilteils 28 weist im Querschnitt schräg verlaufende Außenwände 56 auf, die sich zum ersten Profilteil 20 hin verjüngen, so dass das Einclipsen des zweiten Profilteils 28 in das erste Profilteil 20 vereinfacht ist.The receiving channel 24 facing the end of the second profile member 28 has in cross-section obliquely extending outer walls 56 which taper towards the first profile part 20, so that the Einclipsen of the second profile member 28 is simplified in the first profile part 20.

Grundsätzlich ist es auch möglich, derart lange selbstschneidende zweite Befestigungsschrauben 11 vorzusehen, die bis in das Trägerprofil 2 hindurchgeschraubt werden. In diesem Fall haben die ersten Befestigungsschrauben 10 die das erste Profilteil 20 an dem Trägerprofil 2 befestigen, nur die Aufgabe, das erste Profilteil 20 des Aufsatzprofils 6 in der gewünschten Position vorläufig zu halten, während die gesamte Befestigungsvorrichtung dann im wesentlichen von den zweiten Befestigungsschrauben 11 gehalten würde. In diesem Fall können die Befestigungsschrauben 11 ebenfalls nicht an den Stellen einschraubt werden, an denen sich bereits erste Befestigungsschrauben 10 befinden. Bei einem Trägerprofil 2 aus Vollmaterial müssten die zweiten Befestigungsschrauben 11 in die Sacklöcher 15 des Trägerprofils eingeschraubt werden.In principle, it is also possible to provide such long self-tapping second fastening screws 11, which are screwed into the carrier profile 2. In this case, the first fastening screws 10 which fix the first profile part 20 to the support profile 2, only the task of provisionally holding the first profile part 20 of the attachment profile 6 in the desired position, while the entire fastening device then substantially from the second fastening screws 11th would be held. In this case, the fastening screws 11 also can not be screwed in at the points where there are already first fastening screws 10. In a carrier profile 2 made of solid material, the second fastening screws 11 would have to be screwed into the blind holes 15 of the carrier profile.

Geeigneter sind in diesem Fall Trägerprofile 2 aus einem Hohlprofil, bei denen keine Löcher 15 zum Einschrauben der zweiten Befestigungsschrauben 11 erforderlich sind, da diese selbstschneidenden Befestigungsschrauben durch die Profilwand des Trägerprofils 2 hindurchgeschraubt werden können.In this case, carrier profiles 2 made of a hollow profile, in which no holes 15 are required for screwing in the second fastening screws 11, are more suitable, since these self-tapping fastening screws can be screwed through the profile wall of the carrier profile 2.
