Description

Die Erfindung betrifft eine Vorrichtung zum kreuzweisen Verbinden von horizontal und vertikal verlaufenden Schienen, insbesondere einer Trägerunterkonstruktion für Fassadenverkleidungen, bei der Verbindungsmittel durch Durchbrüche im Bereich der sich kreuzenden Schienen eingeführt und die Schienen mittels dieser Verbindungsmittel gegeneinander verspannt sind.The invention relates to a device for the crosswise connection of horizontally and vertically running rails, in particular a support substructure for facade cladding, in which connecting means are introduced through openings in the area of the crossing rails and the rails are braced against one another by means of these connecting means.

Gerade bei Fassadenverkleidungen setzen sich aus Gründen der verbesserten Feuerfestigkeit immer mehr Trägerunterkonstruktionen aus Metallschienen durch. Dabei werden horizontal verlaufende Schienen eingesetzt, an denen die Fassadenelemente befestigt werden. Die horizontal verlaufenden Schienen wiederum werden in vorgegebenen Abständen auf vertikal verlaufenden Abständen auf vertikal verlaufenden und mit der Wand verbundenen Schienen festgelegt. Dabei bietet sich die Schraubverbindung an den Kreuzungsstellen der Schienen an. Die Verbindungsmittel sind dabei als handelsübliche Schrauben und Muttern ausgebildet.In the case of facade cladding in particular, more and more support substructures made of metal rails are becoming increasingly popular due to their improved fire resistance. Horizontal rails are used, to which the facade elements are attached. The horizontally running rails are in turn fixed at predetermined intervals on vertically running distances on vertically running rails connected to the wall. The screw connection at the crossing points of the rails is ideal. The connecting means are designed as commercially available screws and nuts.

Diese Art der Verbindung von sich kreuzenden Schienen ist aber für den vorgesehenen Zweck aus verschiedenen Gründen nicht geeignet. Zum ersten benötigt der Monteur beide Hände allein für das Einsetzen und Halten der Schraube, sowie das Ansetzen der Mutter. Da vielfach beim kreuzweisen Verbinden von Schienen noch eine Schiene festgehalten werden muß, sind daher meistens zwei Monteure erforderlich. Außerdem ist auch der Teileaufwand pro Verbindungsstelle mit Schraube und Mutter groß und das Festzieben der Mutter benötigt zudem noch eine beachtliche Montagezeit.This type of connection of crossing rails is not suitable for the intended purpose for various reasons. Firstly, the fitter needs both hands to insert and hold the screw and to attach the nut. Since in many cases a rail still has to be held when connecting rails crosswise, two fitters are usually required. In addition, the amount of parts required per connection point with screw and nut is great and tightening the nut also requires a considerable amount of assembly time.

Aus der DE-U 7411 984 ist ein Verbinder bekannt, mit dem zwei C-förmige Schienen rechtwinklig zueinander miteinander verbunden werden können. Die Schlitze der beiden, sich kreuzenden Schienen sind gegeneinander gerichtet. Der Verbinder weist an beiden Enden einen rechteckförmigen Spannsteg auf, der in der Breite auf die Breite des Schlitzes und in der Länge auf den lichten Abstand der Seitenschenkel der Schienen abgestimmt ist. Die beiden Spannstege sind um 90° gegeneinander verdreht. Das Mittelteil des Verbinders hat im Anschluß jeden Spannstegs einen zylindrischen Abstand mit einer auf die Wandstärke der Schienen abgestimmten Länge. Die beiden zylindrischen Abschnitte sind mit einem Werkzeugansatz miteinander verbunden, der den Abstand der beiden Schienen am Kreuzpunkt bestimmt. Mit diesem bekannten Verbinder können zwei Schienen nicht satt aufeinanderliegend miteinander verbunden werden und außerdem ist die Stellung des Verbinders nicht eindeutig festgelegt.From DE-U 7411 984 a connector is known with which two C-shaped rails can be connected to each other at right angles. The slots of the two crossing rails face each other. The connector has a rectangular clamping web at both ends, which is matched in width to the width of the slot and in length to the clear distance between the side legs of the rails. The two tie bars are rotated 90 ° against each other. The middle part of the connector has a cylindrical spacing in the connection of each tensioning web with a length matched to the wall thickness of the rails. The two cylindrical sections are connected to each other with a tool attachment that determines the distance between the two rails at the cross point. With this known connector, two rails cannot be connected to one another in a snug manner, and moreover the position of the connector is not clearly defined.

Die US-A 3 659 884 zeigt die Verbindung zweier plattenförmiger Teile, die im Verbindungsbereich mittels eines plattenförmigen Verbinders miteinander verbunden werden. Der Verbinder ragt mit Ansätzen in einen Schlitz der ersten Platte und steht an der gegenüberliegenden Seite der Platte mit einem Verriegelungsabsatz heraus. Die zweite Platte mit einem Schlitz wird so auf den Verriegelungsansatz des Verbinders aufgeschoben, daß die beiden Schlitze der Platten parallel verlaufen. Dann wird die zweite Platte um 90° verdreht, so daß sich der Verriegelungsansatz hinter dem Schlitz der zweiten Platte abstützt. Diese Verbindungsart ist für eine Trägerkonstruktion einer Fassadenverkleidung ungeeignet, da eine Schiene mit mehreren kreuzenden Schienen verbunden werden muß.US-A 3 659 884 shows the connection of two plate-shaped parts which are connected to one another in the connection area by means of a plate-shaped connector. The connector protrudes into a slot in the first plate and protrudes on the opposite side of the plate with a locking shoulder. The second plate with a slot is pushed onto the locking projection of the connector so that the two slots of the plates are parallel. Then the second plate is rotated by 90 ° so that the locking projection is supported behind the slot of the second plate. This type of connection is unsuitable for a support structure for facade cladding, since one rail must be connected to several crossing rails.

Es ist Aufgabe der Erfindung, eine Vorrichtung zum kreuzweisen Verbinden von horizontal und vertikal verlaufenden Schienen, insbesondere einer Trägerunterkonstruktion für Fassadenverkleidungen, zu schaffen, bei der der Teile- und Montageaufwand pro Verbindungsstelle beachtlich reduziert werden kann und bei der vor allen Dingen das Verbindungsmittel mit einer Hand eingeführt und die Schienen im Verbindungsbereich gegeneinander verspannt werden können.It is an object of the invention to provide a device for the crosswise connection of horizontally and vertically running rails, in particular a support substructure for facade cladding, in which the parts and assembly effort per connection point can be considerably reduced and in which, above all, the connecting means with a Hand inserted and the rails can be braced against each other in the connection area.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Durchbrüche in den Schienen als rechteckförmige Fenster ausgebildet sind, die mit ihrer größeren Abmessung einheitlich in die Längs- bzw. Querrichtung der Schienen ausgerichtet sind, daß die Verbindungsmittel als Spannbolzen mit einem vorderseitigen Spannbund und einem rückseitigen, auf den Querschnitt der Fenster abgestimmten Spannsteg ausgebildet sind und daß der Spannbund und der Spannsteg über einen Abstandsabschnitt miteinander verbunden sind, dessen axiale Länge auf die Summe der Stärken beider Schienen im Verbindungsbereich ausgelegt ist und dessen Querschnitt so gewählt ist, daß er in den Fenstern der Schienen verdrehbar und/oder in Richtung ihrer kleineren Abmessung verspannbar ist.This object is achieved in that the openings in the rails are designed as rectangular windows, which are aligned with their larger dimensions uniformly in the longitudinal or transverse direction of the rails, that the connecting means as clamping bolts with a front clamping collar and a rear, are designed to the cross-section of the window tie bar and that the tension collar and the tie bar are connected to each other via a spacing section, the axial length of which is designed for the sum of the strengths of both rails in the connection area and the cross section is selected such that it is in the windows of the Rails can be rotated and / or clamped in the direction of their smaller dimensions.

Der Spannbolzen wird so angesetzt, daß der Spannsteg mit einem Fenster in der vorderen Schiene fluchtet. Der Spannsteg wird durch das Fenster der vorderen Schiene geführt und dann um 90° verdreht. In dieser neuen Stellung kann der Spannsteg durch das Fenster der hinteren Schiene gesteckt werden. Durch ein erneutes Drehen des Spannbolzens um 90° in der gleichen oder entgegengesetzten Drehrichtung wird der Spannsteg hinter die hintere Schiene eingedreht, so daß er nicht mehr herausgezogen werden kann. Die eingestellte Drehstellung des Spannbolzens läßt sich durch die Verspannung des Abstandsabschnittes in den Fenstern der Schienen festhalten.The clamping bolt is positioned so that the clamping web is aligned with a window in the front rail. The web is led through the window of the front rail and then turned by 90 °. In this new position, the web can be inserted through the window in the rear rail. By turning the clamping bolt 90 ° again in the same or opposite direction of rotation, the clamping web is screwed in behind the rear rail so that it can no longer be pulled out. The set rotational position of the clamping bolt can be held in the windows of the rails by bracing the spacer section.

Eine wesentlich verbesserte Einhaltung der Drehstellung des Spannbolzens, verbunden mit einer erhöhten Verspannung der Schienen im Verbindungsbereich, läßt sich nach einer weiteren Ausgestaltung dadurch erreichen, daß die dem Abstandsabschnitt zugekehrten Spannflächen des Spannsteges in einer vorgegebenen Drehrichtung des Spannbolzens leicht ansteigen, wobei der Abstand zum Spannbund an den Vorderkanten größer und an den Endkanten kleiner ist als die Summe der Stärke der beiden Schienen im Verbindungsbereich.A significantly improved maintenance of the rotational position of the tensioning bolt, combined with increased tensioning of the rails in the connection area, can be achieved according to a further embodiment in that the tensioning surfaces of the tensioning web facing the spacing section rise slightly in a predetermined direction of rotation of the tensioning bolt, the distance to the tension collar is greater at the front edges and smaller at the end edges than the sum of the thickness of the two rails in the connection area.

Zum Verdrehen und Verspannen des Spannbolzens kann auch ein Werkzeug verwendet werden, wenn vorgesehen ist, daß der Spannbund stirnseitig mit einer Werkzeugaufnahme, z. B. Sechskantaufnahme, versehen bzw. selbst als Ansatz, z. B. Sechskantkopf, für ein Werkzeug ausgebildet ist.A tool can also be used to twist and clamp the clamping bolt if it is provided that the clamping collar has a tool holder, eg. B. hexagon socket, provided or even as an approach, z. B. hexagon head, is designed for a tool.

Eine bevorzugte Ausführungsform ist dadurch gekennzeichnet, daß der Spannbund zylinderförmig ausgebildet ist, wobei der Spannbund zylinderförmig ausgebildet ist, wobei der Durchmesser etwa der größeren Abmessung der Fenster in den Schienen entspricht.A preferred embodiment is characterized in that the tension collar is cylindrical, the tension collar cylindrical, the diameter approximately corresponding to the larger dimension of the windows in the rails.

Die Einhaltung der Drehstellung des Spannbolzens über den Abstandsabschnitt wird nach einer Ausgestaltung dadurch in einfacher Weise erreicht, daß der Abstandsabschnitt im Querschnitt etwa rechteckförmig ausgebildet ist, wobei die kleinere Abmessung kleiner und die größere Abmessung gleich oder geringfügig größer ist als die kleinere Abmessung der Fenster in den Schienen. Dabei ist zum kontinuierlichen Festspannen zudem vorgesehen, daß die Schmalseiten des Abstandsabschnittes bogenförmig gestaltet sind, wobei die Krümmung etwa auf die Längsmittelachse des Spannbolzens bezogen ist.According to one embodiment, compliance with the rotational position of the clamping bolt via the spacer section is achieved in a simple manner in that the spacer section is approximately rectangular in cross section, the smaller dimension being smaller and the larger dimension being equal or slightly larger than the smaller dimension of the window in the rails. For continuous tightening, it is also provided that the narrow sides of the spacing section are designed in the shape of an arc, the curvature being approximately related to the longitudinal central axis of the clamping bolt.

Das Einführen des Spannsteges und des Abstandsabschnittes des Spannbolzens in die rechtwinklig zueinander angeordneten rechteckförmigen Durchbrüche der miteinander zu verbindenden Schienen wird dadurch erleichtert, daß der Spannsteg mit seiner kleineren Abmessung der kleineren Abmessung des Abstandsabschnittes entspricht und mit den Flächen der größen Abmessung bündig mit den zugeordneten Flächen des Abstandsabschnittes abschließt. Dabei ist vorzugsweise vorgesehen, daß der Abstandsabschnitt und der Spannsteg symmetrisch zu der Längsmittelachse des Spannbolzens angeordnet sind und daß auch die Schmalseiten des Spannsteges bogenförmig gestaltet sind, wobei die Krümmung etwa auf die Längsmittelachse des Spannbolzens bezogen ist.The insertion of the tensioning web and the spacing section of the tensioning bolt into the rectangular openings of the rails to be connected, which are arranged at right angles to one another, is facilitated in that the tensioning web with its smaller dimension corresponds to the smaller dimension of the spacing section and with the surfaces of the larger dimension flush with the assigned surfaces of the spacing section. It is preferably provided that the spacer section and the tensioning web are arranged symmetrically to the longitudinal central axis of the tensioning bolt and that the narrow sides of the tensioning web are also designed in an arc shape, the curvature being approximately related to the longitudinal central axis of the tensioning bolt.

Nach einer weiteren Ausgestaltung ist zur billigen Herstellung der Verbindungsmittel vorgesehen, daß der Spannbolzen mit dem Spannbund, dem Abstandsabschnitt und dem Spannsteg als einstückiges Metalldrehteil bzw. Metallgußteil hergestellt ist.According to a further embodiment, it is provided for the inexpensive production of the connecting means that the clamping bolt with the clamping collar, the spacing section and the clamping web is produced as a one-piece metal turned part or metal casting.

Die Erfindung wird anhand eines in den Zeichnungen dargestellten Ausführungsbeispiels näher erläutert. Es zeigt :

  • Figur 1 die Draufsicht auf eine Kreuzungsstelle einer horizontalen mit einer vertikalen Schiene,
  • Figur 2 die Seitenansicht eines als Spannbolzen ausgebildeten Verbindungsmittels,
  • Figur 3 die Ansicht des Spannbolzens in Richtung 111 der Fig. 2 und
  • Figur 4 die Ansicht auf die Stirnseite des Spannbundes des Spannbolzens nach Fig. 2.
The invention is explained in more detail using an exemplary embodiment shown in the drawings. It shows :
  • FIG. 1 shows a top view of an intersection of a horizontal and a vertical rail,
  • FIG. 2 shows the side view of a connecting means designed as a clamping bolt,
  • 3 shows the view of the clamping bolt in the direction 111 of FIGS. 2 and
  • 4 shows the view of the end face of the tension collar of the tension bolt according to FIG. 2.

Fig. 1 zeigt eine Kreuzungsstelle einer horizontalen Schiene 20 mit einer vertikalen Schiene 10. Im Ausführungsbeispiel sind die Schienen 10 und 20 gleich und weisen einen rechteckförmigen Querschnitt auf. Dies ist jedoch nicht Voraussetzung für die Erfindung, es lassen sich auch Schienen mit unterschiedlichen Profilen miteinander verbinden. In die Schienen 10 und 20 sind in gleichmäßigen Abständen rechteckförmige Fenster 11 bzw. 21 als Durchbrüche eingebracht, die mit ihrer größeren Abmessung einheitlich in die Längsrichtung der Schienen 10 und 20 ausgerichtet sind. Diese Ausrichtung der Fenster 11 und 21 in den Schienen 10 und 20 kann jedoch auch einheitlich quer zur Längsrichtung derselben erfolgen. Die Schienen 10 und 20 werden so gekreuzt, daß sich ein Fenster 11 mit einem Fenster 21 deckt. Wie Fig. 1 zeigt, bleibt dann nur ein quadratischer Bereich, der in beiden Fenstern 11 und 21 der Schienen 10 und 20 freibleibt.1 shows an intersection of a horizontal rail 20 with a vertical rail 10. In the exemplary embodiment, the rails 10 and 20 are the same and have a rectangular cross section. However, this is not a prerequisite for the invention; rails with different profiles can also be connected to one another. Rectangular windows 11 and 21 are introduced into the rails 10 and 20 at regular intervals as openings which, with their larger dimensions, are aligned uniformly in the longitudinal direction of the rails 10 and 20. This alignment of the windows 11 and 21 in the rails 10 and 20 can, however, also be carried out uniformly transversely to the longitudinal direction of the same. The rails 10 and 20 are crossed so that a window 11 coincides with a window 21. As shown in FIG. 1, only a square area remains, which remains free in both windows 11 and 21 of the rails 10 and 20.

Zur Verbindung der beiden Schienen 10 und 20 wird ein Spannbolzen 12 nach Fig. 2 bis 4 verwendet. Dieser Spannbolzen 12 weist vorderseitig einen zylinderförmigen Spannbund 13 auf, der in der Stirnseite eine Sechskantaufnahme als Werkzeugaufnahme 14 trägt. Der Spannbund 13 geht über einen Abstandsabschnitt 15 in einen Spannsteg 17 über. Dieser Spannsteg 17 weist im wesentlichen den Querschnitt der rechteckigen Fenster 11 und 21 auf, ist aber an seinen Schmalseiten bogenförmig gestaltet, wie Fig. 3 deutlich erkennen läßt. Dieser Spannsteg 17 steht symmetrisch zur Längsmittelachse des Spannbolzens 12. Der Abstandsabschnitt 15 ist in seiner axialen Länge auf die Summe der Stärken der Schienen 10 und 20 im Verbindungsbereich abgestimmt. Bei anderem Schienenprofil ist die Länge des Abstandsabschnittes auf den Abstand der Schienenteile im Bereich der Fenster 11 und 21 abgestimmt. Auch der Abstandsabschnitt 15 hat bogenförmig gestaltete Schmalseiten 16. Die kleinere Abmessung des etwa rechteckförmigen Abstandsabschnittes 15 entspricht der kleineren Abmessung des Spannsteges 17, die etwas kleiner ist als die kleinere Abmessung der Fenster 11 und 21. Die Abmessung des Abstandsabschnittes 15 im Bereich der gewölbten bzw. abgerundeten Schmalseiten 16 ist etwas größer als die kleinere Abmessung der Fenster 11 und 21, so daß der Abstandsabschnitt 15 in einer Drehstellung in einem Fenster 11 bzw. 21 verspannt werden kann.A clamping bolt 12 according to FIGS. 2 to 4 is used to connect the two rails 10 and 20. This clamping bolt 12 has a cylindrical clamping collar 13 on the front, which carries a hexagon receptacle as a tool receptacle 14 in the end face. The tension collar 13 merges into a tensioning web 17 via a spacing section 15. This tensioning web 17 essentially has the cross section of the rectangular windows 11 and 21, but is designed in an arc shape on its narrow sides, as can be clearly seen in FIG. 3. This tensioning web 17 is symmetrical to the longitudinal central axis of the tensioning bolt 12. The axial length of the spacing section 15 is matched to the sum of the thicknesses of the rails 10 and 20 in the connection area. In the case of a different rail profile, the length of the spacing section is matched to the spacing of the rail parts in the area of the windows 11 and 21. The spacer section 15 also has curved narrow sides 16. The smaller dimension of the approximately rectangular spacer section 15 corresponds to the smaller dimension of the tensioning web 17, which is somewhat smaller than the smaller dimension of the windows 11 and 21. The dimension of the spacer section 15 in the area of the curved or rounded narrow sides 16 is somewhat larger than the smaller dimension of the windows 11 and 21, so that the spacing section 15 can be clamped in a window 11 or 21 in a rotational position.

Der zylindrische Spannbund 13 hat einen Durchmesser, der etwa der größeren Abmessung der Fenster 11 und 21 entspricht. Der Spannbund kann jedoch auch selbst als Ansatz, z. B. Sechskantkopf, für ein Werkzeug ausgebildet sein.The cylindrical clamping collar 13 has a diameter which corresponds approximately to the larger dimension of the windows 11 and 21. However, the tension collar itself can also be used as an approach, e.g. B. hexagon head, for a tool.

Der Spannbolzen 12 wird so gehalten, daß der Spannsteg 17 horizontal gerichtet ist. Der Spannsteg 17 kann in dieser Stellung durch das Fenster 21 der vorne liegenden horizontalen Schiene 20 durchgesteckt werden. Dann wird der Spannbolzen 12 um 90° gedreht, so daß der Spannsteg 17 vertikal steht. In dieser Drehstellung kann der Spannsteg 17 dann auch durch das Fenster 11 der hinten liegenden vertikalen Schiene 10 gesteckt werden. Durch ein erneutes Verdrehen des Spannbolzens 12 um 90° wird der Spannsteg 17 hinter die Schiene 10 eingedreht, so daß der Spannbolzen 12 nicht mehr herausgezogen werden kann.The clamping bolt 12 is held so that the clamping web 17 is directed horizontally. The tensioning web 17 can be pushed through the window 21 of the front horizontal rail 20 in this position. Then the clamping bolt 12 is rotated by 90 °, so that the clamping web 17 stands vertically. In this rotational position, the tensioning web 17 can then also be inserted through the window 11 of the vertical rail 10 located at the rear. By turning the clamping bolt 12 again by 90 °, the clamping web 17 is screwed in behind the rail 10, so that the clamping bolt 12 can no longer be pulled out.

Wie leicht einzusehen ist, verspannt sich dabei der Abstandsabschnitt 15 mit den gewölbten Schmalseiten 16 an den Längswänden des Fensters 11 der Schiene 10 und hält damit die Drehstellung des Spannbolzens 12 aufrecht. Es ist leicht einzusehen, daß der Abstand zwischen dem Spannbund 13 und dem Spannsteg 17 maßgebend für die gegenseitige Verspannung der Schienen 10 und 20 im Verbindungsbereich ist. Diese Verspannung der Schienen 10 und 20 läßt sich noch dadurch verbessern, daß die dem Abstandsabschnitt 15 zugekehrten Spannflächen des Spannsteges 17 in einer vorgegebenen Drehrichtung des Spannbolzens 12 jeweils von der Vorderkante zur Endkante ansteigen, wobei der Abstand zum Spannbund 13 an den Vorderkanten größer und an den Endkanten kleiner ist als die Summe der Stärke beider Schienen 10 und 20 im Verbindungsbereich bzw. der Außenabstand der Schienen 10 und 20 im Bereich der sich teilweise überdeckenden Fenster 11 und 21.As can easily be seen, the spacing section 15 braces with the curved narrow sides 16 on the longitudinal walls of the window 11 of the rail 10 and thus maintains the rotational position of the clamping bolt 12. It is easy to see that the distance between the tension collar 13 and the tensioning web 17 is decisive for the mutual bracing of the rails 10 and 20 in the connection area. This bracing of the rails 10 and 20 can be further improved by the fact that the clamping surfaces of the clamping web 17 facing the spacing section 15 rise in each case from the front edge to the end edge in a predetermined direction of rotation of the clamping bolt 12, the distance to the clamping collar 13 being greater and increasing at the front edges the end edges is smaller than the sum of the thickness of both rails 10 and 20 in the connection area or the outer distance of the rails 10 and 20 in the area of the partially overlapping windows 11 and 21.

Der Spannbolzen 12 ist mit einer Hand leicht in die Fenster 11 und 21 der Schienen 10 und 20 einführbar und darin festlegbar. Zum Spannen des Spannbolzens 12 kann dann noch ein Werkzeug verwendet werden, das in die Werkzeugaufnahme 14 eingeführt wird. Mit der anderen Hand kann z. B. die horizontale Schiene 20 gehalten werden, während die horizontale Schiene 10 im Falle einer Trägerunterkonstruktion für Fassadenverkleidungen ja bereits vorher an der Wand angebracht wurde. Es wird deutlich erkennbar, daß die erfindungsgemäße Vorrichtung nur ein einfaches Verbindungsmittel benötigt, das schnell und leicht mit einer Hand eingeführt und gespannt werden kann.The clamping bolt 12 can be easily inserted and fixed in the windows 11 and 21 of the rails 10 and 20 with one hand. A tool that is inserted into the tool holder 14 can then be used to clamp the clamping bolt 12. With the other hand z. B. the horizontal rail 20 are held, while the horizontal rail 10 was already attached to the wall in the case of a support substructure for facade cladding. It can be clearly seen that the device according to the invention only requires a simple connecting means which can be inserted and tensioned quickly and easily with one hand.
