Description

Die Erfindung betrifft eine Befestigungsvorrichtung zur Anbindung einer Diagonalstrebe eines Gerüsts an einen ersten Vertikalstiel des Gerüsts. Die Erfindung betrifft weiterhin ein Gerüst mit einer solchen Befestigungsvorrichtung sowie eine Gerüstanordnung mit einem solchen Gerüst.The invention relates to a fastening device for connecting a diagonal strut of a scaffold to a first vertical post of the scaffold. The invention further relates to a scaffold with such a fastening device and a scaffold arrangement with such a scaffold.

Es ist bekannt, eine Diagonalstrebe eines Gerüsts durch eine Halbkupplung an einem ersten Vertikalstiel eines Gerüsts zu befestigen. Bei Verwendung einer Halbkupplung ist jedoch die genaue Lage und Ausrichtung der Diagonalstrebe nicht bestimmt, d. h. die Halbkupplung kann sowohl in der Höhe am Vertikalstiel, also in dessen Längsrichtung, verschoben werden als auch um den Vertikalstiel gedreht werden. Die Diagonalstrebe kann hierdurch nur unzureichend Normalkräfte, d. h. Kräfte in Längsrichtung der Diagonalstrebe, in den Vertikalstiel einleiten.It is known to attach a diagonal strut of a scaffold to a first vertical post of a scaffold by means of a half coupling. When using a half coupling, however, the exact position and orientation of the diagonal strut is not determined, ie the half coupling can be shifted both in height on the vertical arm, that is in its longitudinal direction, and rotated around the vertical arm. As a result, the diagonal strut can only inadequately introduce normal forces, ie forces in the longitudinal direction of the diagonal strut, into the vertical arm.

In DE 198 42 314 A1 ist modulares Gerüstsystem beschrieben, das aus vertikalen Stielen, an den Stielen vorgesehenen Kupplungen und weiteren Tragelementen zum Anschließen an die Kupplungen besteht. Die Kupplungen sind lösbar und werden form- und/oder kraftschlüssig bedarfsgerecht mit den Stielen verbunden. In EP 1 094 175 A1 ist eine Vorrichtung zur Befestigung der Diagonalstäbe von Leitergerüsten für ein Gerüst beschrieben, welches wenigstens zwei Leitern mit vertikalen Stäben bzw. Holmen und rohrförmigen Sprossen von rundem oder nahezu rundem Querschnitt aufweist, wobei die Leitern miteinander vertikal mittels wenigstens zwei kreuzweise befestigten Diagonalstäben auf jeder Seite der Leiter verbunden sind und die Diagonalstäbe mit ihren Enden an Leitersprossen befestigt sind. Die Vorrichtung weist eine Gruppe von jeweils zur Gelenkverbindung mit einem Ende der Diagonalstäbe bestimmten Klemmorganen auf und jedes Klemmorgan umfasst jeweils zwei beidseits ihrer Gelenkverbindungsachse mit dem Diagonalstab angeordnete Klemmbacken bzw. -schenkel, die voneinander einen Abstand wenigstens gleich der Breite bzw. dem Durchmesser der Holmrohre und höchstens bis auf ein kleines Spiel gleich der Breite der Sprosse an dem Holm besitzen, derart, dass das Klemmorgan seitlich an dem Holm auf dem Niveau einer ausgewählten Sprosse angesetzt und durch Betätigung bis zur Anlage der Klemmbacken bzw. -schenkel an dem Holm auf einem Niveau oberhalb bzw. unterhalb der Sprosse verdreht werden kann, während diese Sprosse mit dem genannten Spiel zwischen den Klemmbacken bzw. -schenkeln eingeschlossen wird.In DE 198 42 314 A1 describes a modular scaffolding system that consists of vertical stems, couplings provided on the stems and other supporting elements for connection to the couplings. The couplings are detachable and are positively and / or non-positively connected to the handles as required. In EP 1 094 175 A1 describes a device for fastening the diagonal bars of ladder scaffolding for a scaffold which has at least two ladders with vertical bars or spars and tubular rungs of round or almost round cross-section, the ladders being connected to one another vertically by means of at least two cross-shaped diagonal bars on each side of the Are connected conductors and the ends of the diagonal bars are attached to ladder rungs. The device has a group of clamping members each intended for articulated connection with one end of the diagonal bars, and each clamping member each comprises two clamping jaws or legs, which are arranged on both sides of their articulation connecting axis with the diagonal bar and which are at a distance from one another at least equal to the width or the diameter of the spar tubes and at most except for a small game equal to the width of the rung on the spar, such that the clamping member is attached to the side of the spar at the level of a selected rung and by actuation until the clamping jaws or legs rest on the spar on one Level above or below the rung can be rotated, while this rung is enclosed with the game between the jaws or legs.

Aufgabe der vorliegenden Erfindung ist es daher, eine Befestigungsvorrichtung, ein Gerüst und eine Gerüstanordnung bereit zu stellen, die eine signifikant verbesserte Aussteifung eines Gerüsts mit einer Diagonalstrebe ermöglichen.The object of the present invention is therefore to provide a fastening device, a scaffold and a scaffold arrangement, which enable a significantly improved stiffening of a scaffold with a diagonal strut.

Die erfindungsgemäße Aufgabe wird durch eine Befestigungsvorrichtung gemäß Patentanspruch 1, ein Gerüst gemäß Patentanspruch 7 sowie eine Gerüstanordnung gemäß Patentanspruch 12 gelöst. Die Unteransprüche geben bevorzugte Weiterbildungen wieder.The object of the invention is achieved by a fastening device according to claim 1, a scaffold according to claim 7 and a scaffold arrangement according to claim 12. The sub-claims reflect preferred further developments.

Die erfindungsgemäße Aufgabe wird somit gelöst durch eine Befestigungsvorrichtung mit einer Diagonalenkupplung zur Anbindung einer Diagonalstrebe des Gerüsts, wobei die Diagonalenkupplung einen ersten Blechabschnitt mit einem ersten Langloch zur teilweisen Aufnahme der Diagonalstrebe aufweist, und einer Vertikalenkupplung zur Anbindung der Befestigungsvorrichtung an einen ersten Vertikalstiel. Die Vertikalenkupplung ist zum zumindest teilweisen Hintergreifen des ersten Vertikalstiels ausgebildet und mit der Diagonalenkupplung verbunden. Weiterhin weist die Befestigungsvorrichtung einen Vorsprung auf, der einenends in eine Stielausnehmung des ersten Vertikalstiels des Gerüsts einführbar ist und anderenends unmittelbar mit der Diagonalenkupplung verbunden ist, wobei die Befestigungsvorrichtung durch den Vorsprung formschlüssig an der Stielausnehmung an dem ersten Vertikalstiel befestigbar ist. Durch die Vertikalenkupplung ist der Vorsprung gegen Herausziehen aus der Stielausnehmung sicherbar. Durch den Eingriff des Vorsprungs in die Stielausnehmung wird somit ein zumindest teilweiser Formschluss zwischen der Befestigungsvorrichtung und dem ersten Vertikalstiel geschaffen, der das Einleiten von Normalkräften der Diagonalstrebe über die Befestigungsvorrichtung in den ersten Vertikalstiel erlaubt.The object of the invention is thus achieved by a fastening device with a diagonal coupling for connecting a diagonal strut of the scaffold, the diagonal coupling having a first sheet metal section with a first elongated hole for partially receiving the diagonal strut, and a vertical coupling for connecting the fastening device to a first vertical post. The vertical coupling is designed to at least partially engage behind the first vertical post and is connected to the diagonal coupling. Furthermore, the fastening device has a projection which can be inserted at one end into a stem recess of the first vertical stem of the scaffold and at the other end is connected directly to the diagonal coupling, the fastening device being able to be fastened in a form-fitting manner to the stem recess on the first vertical stem through the projection. The vertical coupling prevents the projection from being pulled out of the handle recess. The engagement of the projection in the handle recess thus creates an at least partial positive connection between the fastening device and the first vertical handle, which allows normal forces of the diagonal strut to be introduced into the first vertical handle via the fastening device.

Die Befestigungsvorrichtung weist somit einen Vorsprung auf, der in einer Ausnehmung des ersten Vertikalstiels zumindest teilweise einbringbar ist. Der Vorsprung ermöglicht dadurch sowohl eine definierte Festlegung der Befestigungsvorrichtung in Längsrichtung des ersten Vertikalstiels als auch in Drehrichtung um die Längsachse des ersten Vertikalstiels. Hierdurch kann die Diagonalstrebe im Vergleich zur Anbindung gemäß dem Stand der Technik in alle Richtungen volle Kräfte auf den ersten Vertikalstiel übertragen und dennoch flexibel am ersten Vertikalstiel montiert werden.The fastening device thus has a projection which can be at least partially introduced into a recess in the first vertical shaft. The projection thereby enables both a defined fixing of the fastening device in the longitudinal direction of the first vertical stem and also in the direction of rotation around the longitudinal axis of the first vertical stick. As a result, the diagonal strut can transmit full forces in all directions to the first vertical arm in comparison to the connection according to the prior art and yet can be flexibly mounted on the first vertical arm.

Unter einem Vorsprung wird vorzugsweise ein Bolzen bzw. ein Stift mit beliebig geformter Kontur verstanden. Die Stielausnehmung ist vorzugsweise in Form einer Durchgangsausnehmung im ersten Vertikalstiel ausgebildet. Besonders bevorzugt ist der Vorsprung zylinderförmig ausgebildet.A projection is preferably understood to mean a bolt or a pin with an arbitrarily shaped contour. The stem recess is preferably formed in the form of a passage recess in the first vertical stem. The projection is particularly preferably cylindrical.

Vorzugsweise kann die Vertikalenkupplung den ersten Vertikalstiel vollständig umgreifen. Hierdurch ist die Befestigungsvorrichtung besonders sicher am ersten Vertikalstiel befestigbar.The vertical coupling can preferably completely encompass the first vertical post. As a result, the fastening device can be fastened particularly securely to the first vertical post.

Die Vertikalenkupplung kann zur zumindest teilweisen formschlüssigen Anbindung an den ersten Vertikalstiel und/oder zur kraftschlüssigen Anbindung an den ersten Vertikalstiel ausgebildet sein.The vertical coupling can be designed for at least partially positive connection to the first vertical shaft and / or for non-positive connection to the first vertical shaft.

Besonders bevorzugt ist die Vertikalenkupplung in Form einer Halbkupplung ausgebildet. Da ein Gerüstbauer an die Montage und Demontage von Halbkupplungen gewohnt ist, kann er die erfindungsgemäße Befestigungsvorrichtung intuitiv am ersten Vertikalstiel anordnen und entfernen.The vertical coupling is particularly preferably designed in the form of a half coupling. Since a scaffolding engineer is used to the assembly and disassembly of half couplings, he can intuitively arrange and remove the fastening device according to the invention on the first vertical post.

Der Vorsprung wird vorzugsweise durch ein erstes Ende eines Bügels ausgebildet. Der Bügel ist weiter bevorzugt anderenends unmittelbar mit der Diagonalenkupplung verbunden sein. Dies ermöglicht eine unmittelbare Kraftübertragung von der Diagonalstrebe in die Diagonalenkupplung und dadurch weiter zur Stielausnehmung.The protrusion is preferably formed by a first end of a bracket. The bracket is further preferably connected directly to the diagonal coupling at the other end. This enables direct power transmission from the diagonal strut into the diagonal coupling and thus further to the stem recess.

Weiterhin ist es aus statischen Gründen bevorzugt, wenn die Diagonalenkupplung starr mit der Vertikalenkupplung verbunden ist.Furthermore, for static reasons it is preferred if the diagonal coupling is rigidly connected to the vertical coupling.

Erfindungsgemäß weist die Diagonalenkupplung einen ersten Blechabschnitt mit einem ersten Langloch auf, in das die Diagonalstrebe teilweise aufnehmbar ist.According to the invention, the diagonal coupling has a first sheet metal section with a first elongated hole, into which the diagonal strut can be partially received.

Die Diagonalenkupplung kann einen zweiten Blechabschnitt aufweisen, wobei der zweite Blechabschnitt ein zweites Langloch zur teilweisen Aufnahme einer weiteren Diagonalstrebe aufweist. Das erste Langloch fluchtet dabei vorzugsweise mit dem zweiten Langloch.The diagonal coupling can have a second sheet metal section, the second sheet metal section having a second elongated hole for partially receiving a further diagonal strut. The first slot is preferably aligned with the second slot.

Die Befestigungsvorrichtung ist konstruktiv besonders einfach und stabil ausgebildet, wenn der erste Blechabschnitt über einen Verbindungsblechabschnitt mit dem zweiten Blechabschnitt verbunden ist.The fastening device is structurally particularly simple and stable if the first sheet metal section is connected to the second sheet metal section via a connecting sheet metal section.

Die erfindungsgemäße Aufgabe wird weiterhin gelöst durch ein Gerüst mit einem ersten Vertikalstiel und einer zuvor beschriebenen Befestigungsvorrichtung. Der erste Vertikalstiel weist eine Stielausnehmung, insbesondere in Form einer Durchgangsausnehmung, auf, in die der Vorsprung zumindest teilweise eingeführt ist. Die Vertikalenkupplung der Befestigungsvorrichtung hintergreift zumindest teilweise den ersten Vertikalstiel.The object of the invention is further achieved by a scaffold with a first vertical post and a fastening device described above. The first vertical stem has a stem recess, in particular in the form of a passage recess, into which the projection is at least partially inserted. The vertical coupling of the fastening device engages behind the first vertical post at least partially.

Vorzugsweise umgreift die Vertikalenkupplung den ersten Vertikalstiel vollständig.The vertical coupling preferably completely engages around the first vertical post.

Die Stielausnehmung im ersten Vertikalstiel ist vorzugsweise dazu ausgebildet, einen im ersten Vertikalstiel eingeführten Zapfen durch einen Stift zu sichern, der sowohl durch den ersten Vertikalstiel als auch den Zapfen geführt ist. Mit anderen Worten ist der Vorsprung vorzugsweise in eine Stielausnehmung in Form einer Durchgangsausnehmung eingeführt, die bereits am ersten Vertikalstiel ausgebildet ist, um einen weiteren Vertikalstiel am ersten Vertikalstiel zu sichern. Hierdurch muss am ersten Vertikalstiel keine zusätzliche Stielausnehmung ausgebildet werden. Vielmehr kann ein herkömmlicher erster Vertikalstiel im Zusammenspiel mit der erfindungsgemäßen Befestigungsvorrichtung eingesetzt werden.The stem recess in the first vertical stem is preferably designed to insert a pin inserted into the first vertical stem To secure the pin that is guided through both the first vertical stem and the pin. In other words, the protrusion is preferably inserted into a stem recess in the form of a passage recess which is already formed on the first vertical stem in order to secure a further vertical stem on the first vertical stem. As a result, no additional handle recess has to be formed on the first vertical handle. Rather, a conventional first vertical handle can be used in conjunction with the fastening device according to the invention.

Vorzugsweise weist das Gerüst einen solchen weiteren Vertikalstiel mit einem endseitigen Zapfen auf, wobei der Zapfen in den ersten Vertikalstiel einführbar ist und wobei der Zapfen eine Zapfenbohrung aufweist, in die der Vorsprung teilweise eingeführt ist, um den ersten Vertikalstiel am weiteren Vertikalstiel zu sichern. Der Vorsprung erfüllt in diesem Fall eine Doppelfunktion: Einerseits sichert er die Befestigungsvorrichtung drehfest und verschiebefest am ersten Vertikalstiel, andererseits sichert er den weiteren Vertikalstiel verschiebefest und drehfest am ersten Vertikalstiel.The scaffold preferably has such a further vertical shaft with an end-side pin, the pin being insertable into the first vertical shaft and the pin having a pin hole into which the projection is partially inserted in order to secure the first vertical shaft on the further vertical shaft. In this case, the protrusion fulfills a double function: on the one hand it secures the fastening device in a rotationally fixed and non-displaceable manner on the first vertical arm, on the other hand it secures the further vertical arm in a non-rotatable and non-rotatable manner on the first vertical arm.

Alternativ dazu kann der Vorsprung so kurz ausgebildet sein, dass er nur so weit in den ersten Vertikalstiel ragt, dass eine in den Vertikalstiel eingeführte Spindel den Vorsprung berührungsfrei in Längsrichtung des ersten Vertikalstiels passieren kann. Die Spindel ist dabei vorzugsweise Teil eines Stützfußes des Gerüsts.As an alternative to this, the projection can be made so short that it only projects so far into the first vertical shaft that a spindle inserted into the vertical shaft can pass the projection without contact in the longitudinal direction of the first vertical shaft. The spindle is preferably part of a support foot of the frame.

Weiter bevorzugt weist das Gerüst eine Diagonalstrebe auf, wobei die Diagonalstrebe einenends an der Diagonalenkupplung befestigt ist und anderenends mittelbar oder unmittelbar an einem zweiten Vertikalstiel befestigt ist. Die Diagonalstrebe ist dabei vorzugsweise an einem Langloch des zweiten Vertikalstiels befestigt. Der zweite Vertikalstiel ist dadurch um seine Längsachse drehfest relativ zur Diagonalstrebe angeordnet.The scaffold further preferably has a diagonal strut, the diagonal strut being attached at one end to the diagonal coupling and at the other end being attached indirectly or directly to a second vertical post. The diagonal strut is preferably attached to an elongated hole in the second vertical post. The second vertical post is thus arranged in a rotationally fixed manner about its longitudinal axis relative to the diagonal strut.

Horizontalkräfte, wie sie beispielsweise aus Windlasten oder (vertikalen) Abtriebskräften bei Schiefstellung des Vertikalstiels entstehen, können hierdurch zuverlässiger vom zweiten Vertikalstiel auf den ersten Vertikalstiel übertragen werden, wodurch das Gerüst signifikant ausgesteift ist.Horizontal forces, such as those resulting from wind loads or (vertical) downforce when the vertical arm is tilted, can be more reliably transmitted from the second vertical arm to the first vertical arm, which significantly stiffens the scaffold.

In weiter bevorzugter Ausgestaltung der Erfindung ist das Gerüst in Form eines Fassadengerüsts ausgebildet. Das Gerüst kann dabei in Form eines Rahmengerüsts oder eines Modulgerüsts ausgebildet sein.In a further preferred embodiment of the invention, the scaffold is designed in the form of a facade scaffold. The scaffold can be designed in the form of a frame scaffold or a modular scaffold.

Die erfindungsgemäße Aufgabe wird weiterhin gelöst durch eine Gerüstanordnung, wobei die Gerüstanordnung ein zuvor beschriebenes Gerüst und ein Bauwerk aufweist und wobei der erste Vertikalstiel in Form eines Innenstiels ausgebildet ist, der im Gegensatz zu einem Außenstiel des Gerüsts näher am Bauwerk angeordnet ist.The object according to the invention is further achieved by a scaffold arrangement, the scaffold arrangement having a previously described scaffold and a structure, and the first vertical column being designed in the form of an inner column which, in contrast to an outer column of the scaffold, is arranged closer to the structure.

Weiter bevorzugt ist der zweite Vertikalstiel in Form eines Innenstiels ausgebildet, der ebenfalls dem Bauwerk zugewandt ist. Das erfindungsgemäße Gerüst weist hierdurch eine deutlich verbesserte Kraftübertragung über die Diagonalstrebe in Form einer Innendiagonalen auf. Das Gerüst weist eine versteifte statische Innenscheibe auf, wodurch weniger Fassadenanker zur Befestigung des Gerüsts am Bauwerk zur Abstützung parallel zum Bauwerk eingesetzt werden müssen. Somit kann das Gerüst als freistehende Scheibe parallel zur Fassade montiert werden. Insbesondere müssen keine Dreiecksanker zur Sicherung des Gerüsts an der Fassade eingesetzt werden.More preferably, the second vertical post is in the form of an inner post which also faces the building. As a result, the scaffold according to the invention has a significantly improved power transmission via the diagonal strut in the form of an internal diagonal. The scaffold has a stiffened static inner pane, which means that fewer facade anchors have to be used to fasten the scaffold to the structure and to support it parallel to the structure. This means that the scaffold can be installed as a free-standing pane parallel to the facade. In particular, no triangular anchors have to be used to secure the scaffolding on the facade.

Figur 1 zeigt ein Gerüst 10 mit einem ersten Vertikalstiel 12 und einem zweiten Vertikalstiel 14. Die beiden Vertikalstiele 12, 14 sind über eine Diagonalstrebe 16 verbunden. Die Diagonalstrebe 16 ist oberenends unmittelbar an einem Langloch 18 des zweiten Vertikalstiels 14 angeordnet. Die Diagonalstrebe 16 ist dabei oberenends derart am Langloch 18 befestigt, dass eine Horizontalkraft aus dem zweiten Vertikalstiel 14 unmittelbar als Normalkraft in die Diagonalstrebe 16 eingeleitet wird. Unterenends ist die Diagonalstrebe 16 über eine torsionssteife Befestigungsvorrichtung 20 derart am ersten Vertikalstiel 12 angeordnet, dass die Normalkraft aus der Diagonalstrebe 16 in den ersten Vertikalstiel 12 eingeleitet werden kann. Die Vertikalstiele 12, 14 können durch Stützfüße 22, 24 (in Figur 1 schematisch gestrichelt angedeutet) am Boden 26 abgestützt sein. Alternativ dazu können die Vertikalstiele 12, 14 unterenends mit weiteren Vertikalstielen (nicht gezeigt) verbunden sein. Auch ist eine zusätzliche Verbindung der Vertikalstiele durch Horizontalriegel (nicht gezeigt) möglich. Figure 1 shows a scaffold 10 with a first vertical post 12 and a second vertical post 14. The two vertical posts 12, 14 are connected via a diagonal strut 16 . The diagonal strut 16 is arranged at the top end directly on an elongated hole 18 of the second vertical post 14. The diagonal strut 16 is fastened at the top end to the elongated hole 18 in such a way that a horizontal force from the second vertical post 14 is directly introduced into the diagonal strut 16 as a normal force. At the lower end, the diagonal strut 16 is arranged on the first vertical arm 12 via a torsionally rigid fastening device 20 such that the normal force from the diagonal strut 16 is in the first Vertical stem 12 can be initiated. The vertical stems 12, 14 can be supported by feet 22, 24 (in Figure 1 schematically indicated by dashed lines) on the floor 26 . Alternatively, the vertical stems 12, 14 can be connected at the lower ends to further vertical stems (not shown). An additional connection of the vertical supports by means of horizontal bars (not shown) is also possible.

Figur 2 zeigt eine Gerüstanordnung 28 mit dem Gerüst 10 und einem Bauwerk 30. Das Bauwerk 30 ist in Figur 2 lediglich schematisch angedeutet. Der erste Vertikalstiel 12 ist dabei nahe dem Bauwerk 30 aufgestellt. Ein Außenstiel 32 verläuft parallel zum ersten Vertikalstiel 12. Im Gegensatz zum Außenstiel 32, der weiter beabstandet zum Bauwerk 30 aufgestellt ist als der erste Vertikalstiel 12, ist der erste Vertikalstiel 12 in Form eines Innenstiels, d. h. dem Bauwerk 30 zugewandt, ausgebildet. Die Diagonalstrebe 16 verläuft somit ebenfalls in Bezug auf das Gerüst 10 dem Bauwerk 30 zugewandt. Die Diagonalstrebe 16 steift daher statisch gesehen eine Innenscheibe des Gerüsts 10 aus. Die Befestigungsvorrichtung 20 ist reversibel lösbar am ersten Vertikalstiel 12 angeordnet. Figure 2 shows a scaffold arrangement 28 with the scaffold 10 and a structure 30. The structure 30 is in Figure 2 only indicated schematically. The first vertical post 12 is placed near the structure 30. An outer stem 32 runs parallel to the first vertical stem 12. In contrast to the outer stem 32, which is set up at a greater distance from the structure 30 than the first vertical stem 12, the first vertical stem 12 is designed in the form of an inner stem, ie facing the structure 30. The diagonal strut 16 thus also faces the building 30 with respect to the scaffold 10. From a static point of view, the diagonal strut 16 therefore stiffens an inner pane of the framework 10. The fastening device 20 is arranged reversibly detachably on the first vertical handle 12.

Figur 3 zeigt eine vergrößerte Ansicht des Gerüsts 10 im Bereich der Befestigungsvorrichtung 20. Aus Figur 3 ist ersichtlich, dass die Diagonalstrebe 16 endseitig eine Nase 34 aufweist, die die Befestigungsvorrichtung 20 hintergreift. Die Diagonalstrebe 16 weist beidenends (nicht gezeigt) eine Nase 34 auf. Die Diagonalstrebe 16 ist dabei derart torsionssteif an der Befestigungsvorrichtung 20 angeordnet, dass eine Normalkraft aus der Diagonalstrebe 16 über die Befestigungsvorrichtung 20 auf den Vertikalstiel 12 übertragen wird. Figure 3 shows an enlarged view of the scaffold 10 in the region of the fastening device 20. From Figure 3 it can be seen that the diagonal strut 16 has a nose 34 at the end, which engages behind the fastening device 20. The diagonal strut 16 has a nose 34 at both ends (not shown). The diagonal strut 16 is arranged torsionally rigid on the fastening device 20 in such a way that a normal force from the diagonal strut 16 is transmitted to the vertical arm 12 via the fastening device 20.

Figur 4 zeigt das Gerüst 10 ohne die Diagonalstrebe 16 (siehe Figur 3). Aus Figur 4 ist ersichtlich, dass die Befestigungsvorrichtung 20 eine Vertikalenkupplung 36 in Form einer Halbkupplung aufweist. Eine Diagonalenkupplung 38 ist starr mit der Vertikalenkupplung 36 verbunden. Mit anderen Worten ist die Diagonalenkupplung 38 unbewegbar zur Vertikalenkupplung 36 ausgebildet. An der Diagonalenkupplung 38 ist ein Vorsprung 40 angeordnet, der in eine Stielausnehmung 42 des ersten Vertikalstiels 12 eindringt. Der Vorsprung 40 ist Teil eines Bügels 43 der Befestigungsvorrichtung 20. Die Stielausnehmung 42 ist in Form einer Durchgangsausnehmung in einer Wandung 44 des ersten Vertikalstiels 12 ausgebildet. Durch den in die Stielausnehmung 42 eingreifenden Vorsprung 40 ist die Befestigungsvorrichtung 20 sowohl in Richtung der zentralen Längsachse 46 des ersten Vertikalstiels 12 als auch drehfest um die zentrale Längsachse 46 des ersten Vertikalstiels 12 am ersten Vertikalstiel 12 gesichert. Figure 4 shows the scaffold 10 without the diagonal strut 16 (see Figure 3 ). Out Figure 4 it can be seen that the fastening device 20 has a vertical coupling 36 in the form of a half coupling. A diagonal coupling 38 is rigidly connected to the vertical coupling 36. In other words, the diagonal coupling 38 is designed to be immovable relative to the vertical coupling 36. A projection 40 is arranged on the diagonal coupling 38 and penetrates into a stem recess 42 of the first vertical stem 12. The projection 40 is part of a bracket 43 of the fastening device 20. The handle recess 42 is designed in the form of a passage recess in a wall 44 of the first vertical handle 12. By means of the projection 40 engaging in the stem recess 42, the fastening device 20 is secured to the first vertical stem 12 both in the direction of the central longitudinal axis 46 of the first vertical stem 12 and in a rotationally fixed manner about the central longitudinal axis 46 of the first vertical stem 12.

Die Diagonalenkupplung 38 weist einen ersten Blechabschnitt 48 und einen zweiten Blechabschnitt 50 auf. Der erste Blechabschnitt 48 ist über einen Verbindungsblechabschnitt 52 mit dem zweiten Blechabschnitt 50 verbunden. Der erste Blechabschnitt 48 weist ein erstes Langloch 54 und der zweite Blechabschnitt 50 ein zweites Langloch 56 auf. Die Langlöcher 54, 56 sind zueinander fluchtend ausgebildet. In das erste Langloch 54 bzw. das zweite Langloch 56 ist jeweils eine Nase 34 (siehe Figur 3) einer Diagonalstrebe 16 (siehe Figur 3) einführbar. An der Befestigungsvorrichtung 20 können somit gleichzeitig zwei Diagonalstreben 16 (siehe eine Diagonalstrebe 16 in Figur 3) angeordnet werden.The diagonal coupling 38 has a first sheet metal section 48 and a second sheet metal section 50 . The first sheet metal section 48 is connected to the second sheet metal section 50 via a connecting sheet metal section 52 . The first sheet metal section 48 has a first slot 54 and the second sheet section 50 has a second slot 56 . The elongated holes 54, 56 are designed to be in alignment with one another. In each of the first slot 54 and the second slot 56 there is a nose 34 (see Figure 3 ) a diagonal strut 16 (see Figure 3 ) importable. Thus, two diagonal struts 16 (see a diagonal strut 16 in FIG Figure 3 ) to be ordered.

Der Vorsprung 40 durchgreift sowohl den ersten Blechabschnitt 48 als auch den zweiten Blechabschnitt 50. Hierdurch ist eine Kraftübertragung vom ersten Vertikalstiel 12 auf den Vorsprung 40 und weiter auf die Blechabschnitte 48, 50 besonders effektiv.The projection 40 extends through both the first sheet metal section 48 and the second sheet metal section 50. As a result, a force transmission from the first vertical post 12 to the projection 40 and further onto the sheet metal sections 48, 50 is particularly effective.

Figur 5 zeigt das Gerüst 10 gemäß Figur 4 in einer Ansicht von oben. Aus Figur 5 ist ersichtlich, dass die Vertikalenkupplung 36 den ersten Vertikalstiel 12 vollumfänglich umgreift. Die Befestigungsvorrichtung 20 ist dadurch besonders sicher am ersten Vertikalstiel 12 gehalten. Figur 5 verdeutlicht weiterhin, dass der Vorsprung 40 nur geringfügig in den ersten Vertikalstiel 12 hineinragt. Eine Spindel 58 (in Figur 5 gestrichelt angedeutet) kann hierdurch, beispielsweise zur Höhenverstellung eines Stützfußes 22, 24 (siehe Figur 1), in Richtung der zentralen Längsachse 46 (siehe Figur 4) am Vorsprung 40 vorbeigeführt werden. Die Spindel 58 ist in Figur 5 aus Gründen der Übersichtlichkeit mit verkleinertem Durchmesser angedeutet. In der Regel weist die Spindel 58 einen Außendurchmesser auf, der etwas kleiner ist als die lichte Weite des Vertikalstiels 12, d. h. der Außendurchmesser der Spindel 58 entspricht ungefähr der gestrichelten Linie 62. Figure 5 shows the scaffold 10 according to Figure 4 in a top view. Out Figure 5 it can be seen that the vertical coupling 36 completely encompasses the first vertical post 12. The fastening device 20 is thereby held particularly securely on the first vertical arm 12. Figure 5 further clarifies that the projection 40 projects only slightly into the first vertical post 12. A spindle 58 (in Figure 5 indicated by dashed lines) can thereby, for example for the height adjustment of a support leg 22, 24 (see Figure 1 ), in the direction of the central longitudinal axis 46 (see Figure 4 ) are led past the projection 40. The spindle 58 is in Figure 5 indicated for the sake of clarity with a reduced diameter. As a rule, the spindle 58 has an outside diameter that is somewhat smaller than the inside width of the vertical shaft 12, ie the outside diameter of the spindle 58 corresponds approximately to the dashed line 62.

Alternativ zu dem in Figur 5 gezeigten Vorsprung 40 kann der Vorsprung 40 endseitig länger ausgebildet sein, sodass er den Innenraum des ersten Vertikalstiels 12 vollständig oder nahezu vollständig durchragt. Dies ist in Figur 5 durch einen mit strichpunktierten Linien angedeuteten verlängerten Vorsprung 40 angedeutet. In diesem Fall kann der Vorsprung 40 zusätzlich zu seiner Sicherungsfunktion für die Befestigungsvorrichtung 20 eine Sicherung des ersten Vertikalstiels 12 zu einem weiteren Vertikalstiel 60 darstellen. Der erste Vertikalstiel 12 ist dabei auf den weiteren Vertikalstiel 60 aufgesteckt. Der weitere Vertikalstiel 60 weist einen Zapfen 62 auf, dessen zentrale Längsachse sich mit der zentralen Längsachse 46 (siehe Figur 4) des ersten Vertikalstiels 12 deckt. Die Kontur des Zapfens 62 ist in Figur 5 strichpunktiert angedeutet. Der Zapfen 62 weist eine erste Zapfenbohrung 64 auf, die von dem strichpunktiert verlängert dargestellten Vorsprung 40 durchdrungen ist. Zusätzlich dazu kann der Zapfen 62 eine zweite Zapfenbohrung 66 aufweisen, die mit der ersten Zapfenbohrung 64 fluchtet. Der Vorsprung 40 kann so lang ausgebildet sein, dass er die zweite Zapfenbohrung 66 durchdringt. Der weitere Vertikalstiel 60 wird hierdurch über den Zapfen 62 besonders sicher am ersten Vertikalstiel 12 gehalten.Alternatively to that in Figure 5 The projection 40 shown can have a longer end 40, so that it projects completely or almost completely through the interior of the first vertical post 12. This is in Figure 5 indicated by an elongated projection 40 indicated by dash-dotted lines. In this case, in addition to its securing function for the fastening device 20, the projection 40 can represent securing the first vertical post 12 to a further vertical post 60 . The first vertical arm 12 is plugged onto the further vertical arm 60. The further vertical stem 60 has a pin 62 , the central longitudinal axis with the central longitudinal axis 46 (see Figure 4 ) of the first vertical stem 12 covers. The contour of the pin 62 is in Figure 5 indicated by dash-dotted lines. The pin 62 has a first pin bore 64 , which is penetrated by the projection 40, which is shown as a dash-dot line. In addition, the pin 62 may have a second pin bore 66 that is aligned with the first pin bore 64. The projection 40 can be made so long that it penetrates the second pin bore 66. The further vertical arm 60 is thereby held particularly securely on the first vertical arm 12 by means of the pin 62.

Die Stielausnehmung 42 in Form einer Durchgangsausnehmung ist vorzugsweise am ersten Vertikalstiel 12 vorgesehen, um den Zapfen 62 am ersten Vertikalstiel 12 mit einem Stift zu sichern. Zur Befestigung der Befestigungsvorrichtung 20 muss der erste Vertikalstiel 12 in diesem Fall nicht mit einer zusätzlichen Stielausnehmung 42 ausgebildet werden. Es kann vielmehr eine bereits vorhandene in Form einer Bohrung ausgebildete Stielausnehmung 42 zur Anordnung der Befestigungsvorrichtung 20 eingesetzt werden. Der Stielausnehmung 42 gegenüberliegend kann der erste Vertikalstiel 12 eine weitere Stielausnehmung 68 aufweisen, die mit der Stielausnehmung 42 fluchtet. Der Vorsprung 40 kann in diesem Fall so lang ausgebildet sein (nicht gezeigt) dass er die weitere Stielausnehmung 68 ebenfalls durchgreift. Die Befestigungsvorrichtung 20 ist dadurch besonders drehsicher an dem ersten Vertikalstiel 12 anordenbar.The stem recess 42 in the form of a passage recess is preferably provided on the first vertical stem 12 in order to secure the pin 62 on the first vertical stem 12 with a pin. In this case, the first vertical post 12 does not have to be formed with an additional post recess 42 for attaching the fastening device 20. Rather, an already existing handle recess 42 in the form of a bore can be used to arrange the fastening device 20. Opposite the stem recess 42, the first vertical stem 12 can have a further stem recess 68 which is aligned with the stem recess 42. In this case, the projection 40 can be made so long (not shown) that it also extends through the further handle recess 68. The fastening device 20 can thereby be arranged in a particularly rotationally secure manner on the first vertical handle 12.
