Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine Geländervorrichtung für ein Systemgerüst mit einem orthogonal Bezugssystem mit einer Breitenrichtung, einer Höhenrichtung und einer Querrichtung mit Gerüstetagen mit in Breitenrichtung beabstandet angeordneten Vertikalstielen, in Querrichtung an die Vertikalstiele angeschlossene Querriegel und an den Querriegeln in Breitenrichtung verlaufende angeschlossene Gerüstbelägen, wobei die Geländervorrichtung als sogenannte voreilende Geländervorrichtung ausgebildet ist, die von einer bestehenden unteren Gerüstetage aus für eine darüber zu montierende obere Gerüstetage montiert wird und die dann einen Seitenschutz für die obere Gerüstetage bildet, zumindest ein in Breitenrichtung verlaufenden oberen Geländerstab, auch Handlauf genannt, aufweist, einen rechten Vertikalgeländerstiel und einen linken Vertikalgeländerstiel aufweist, der rechte und linke Vertikalgeländerstiel rechte und linke Anschlusseinheiten zum lösbaren Anschluss an die Vertikalstiele des Systemgerüsts aufweist.The present invention relates to a railing device for a system scaffolding with an orthogonal reference system with a width direction, a height direction and a transverse direction with scaffold levels with vertical standards arranged spaced apart in the width direction, crossbars connected to the vertical standards in the transverse direction and scaffolding decking connected to the crossbars running in the width direction, wherein the Railing device is designed as a so-called leading railing device, which is mounted from an existing lower scaffolding level for an upper scaffolding level to be mounted above and which then forms side protection for the upper scaffolding level, has at least one upper railing rod, also called a handrail, running in the width direction, has a right vertical railing post and a left vertical railing post having the right and left vertical railing post right and left connection units for detachable connection to the vertical posts of the system scaffold.

In der Regel wird ein Seitenschutz mit einem Geländerholm erst montiert, wenn der Gerüstbauer auf der zu bearbeitenden Gerüstetage steht. Das ist gefährlich, da der Gerüstbauer ohne Seitenschutz in großen Höhen freisteht und im schlimmsten Fall vom Gerüst fallen kann. Um die Sicherheit zu erhöhen werden daher so genannte voreilende Geländer eingesetzt, die einen Seitenschutz auf der oberen zu bearbeitenden Gerüstetage gewährleisten.As a rule, side protection with a railing is only installed when the scaffolder is standing on the scaffolding level to be worked on. This is dangerous because the scaffolder is free at great heights without side protection and, in the worst case, can fall off the scaffolding. In order to increase safety, so-called leading railings are used, which ensure side protection on the upper scaffolding level to be worked on.

Derartige voreilende Geländer bestehen pro Gerüstfeld in der Regel aus insgesamt drei oder vier einzelnen Bauteilen, nämlich aus zwei identischen Geländerpfosten, die an bestehende Vertikalstiele des Gerüsts angeschlossen werden und an die zumindest ein, insbesondere zwei teleskopierbare Geländerholme angeschlossen sind. Die Geländerpfosten mit den angeschlossenen Geländerholmen werden aus der jeweils darunterliegenden Gerüstetage montiert und stellen so aufgrund ihrer Länge einen zumindest einteiligen Seitenschutz in der nächsten, oberen Gerüstetage zur Verfügung. Je nach Baufortschritt wird immer jeweils ein weiterer Geländerpfosten des voreilenden Geländers sukzessive in die Geländervorrichtung nach oben hin versetzt, um die obere Gerüstetage für weitere Montagearbeiten zu sichern. Die Demontage erfolgt in umgekehrter Reihenfolge.Leading railings of this type usually consist of a total of three or four individual components per scaffolding bay, namely two identical railing posts that are connected to existing vertical posts of the scaffolding and to which at least one, in particular two, telescopic railings are connected. The railing posts with the connected railings are assembled from the scaffolding level below and, due to their length, provide at least one-piece side protection on the next, upper scaffolding level. Depending on the progress of construction, one additional railing post of the leading railing is successively moved upwards into the railing device in order to secure the upper scaffolding level for further assembly work. Dismantling is carried out in reverse order.

STAND DER TECHNIKSTATE OF THE ART

Aus der DE 10 2009 024 816 A ist ein Geländerpfosten für ein voreilendes Geländer bekannt, der zwei scherenartige Klauen besitzt, die zum Anschluss aktiv geöffnet und geschlossen werden müssen. Als Arretierung und Sicherung im unteren Bereich der scherenartigen Klauen dient ein Zapfen. Um einen Formschluss zu gewährleisten, muss das äußere Pfostenrohr des Geländerpfostens vertikal verschoben, anschließend verdreht und wieder abgesenkt werden. Die Entsicherung erfolgt in umgekehrter Reihenfolge. Ein Nachteil bei diesem voreilenden Geländer ist hierbei, dass bei der Montage und Demontage des voreilenden Geländes eine unangenehme vertikale sowie horizontale Bewegung durchgeführt werden muss. Zudem muss bei der Montage darauf geachtet werden, dass die oberen und unteren scherenartigen Klauen am anzubringenden Vertikalrahmen oder Vertikalstiel vollständig angeschlossen sind und diesen auch umschließen.From the DE 10 2009 024 816 A a railing post for a leading railing is known which has two scissor-like claws which must be actively opened and closed for connection. A pin is used to lock and secure the lower part of the scissor-like claws. To ensure a form fit, the outer post tube of the railing post must be moved vertically, then twisted and lowered again. Unlocking takes place in reverse order. A disadvantage of this leading railing is that an awkward vertical and horizontal movement has to be carried out when assembling and dismounting the leading railing. In addition, during assembly, care must be taken to ensure that the upper and lower scissor-like claws are fully connected to the vertical frame or vertical post to be attached and also enclose it.

Die EP 1 338 723 A2 offenbart eine Vorrichtung zur Montage eines temporär vorhandenen Geländerholms eines Gerüsts, bei dem die dritte untere Anschlusseinrichtung an bestehenden Geländerholmen eingehängt wird und die zweite Anschlusseinrichtung mittels einer U- förmigen Aufnahmeeinheit mit Keileinheit an den Geländerholm angeschlossen wird.The EP 1 338 723 A2 discloses a device for mounting a temporary railing of a scaffolding, in which the third lower connection device is hung on existing railings and the second connection device by means of a U-shaped receiving unit with wedge unit is connected to the railing.

Die EP 1 571 275 A2 offenbart eine Vorrichtung zur Montage eines temporär vorhandenen Geländerpfostens mit angeschlossenen teleskopierbaren Geländerholmen an bestehende Vertikalstiele eines Gerüsts gemäß den Merkmalen des Oberbegriffs des Anspruchs 1. Der Geländerpfosten besitzt Klauen mit einer automatischen Klemmfunktion, wobei eine durchgehende drehbare Welle im Innern des Geländerpfostens eingesetzt wird, die über Betätigungseinheiten drehbar betätigbar ist und über eine relativ aufwändige Mechanik mit den Klauen in Verbindung steht. Durch eine Drehbewegung der Betätigungseinheit müssen zum Anschluss des Vertikalstiels an den Geländerpfosten diese aktiv geöffnet und geschlossen werden. Hierzu wird die Betätigungseinheit entsprechend verdreht. Als nachteilig wird bei dieser Lösung empfunden, dass bei der Montage und Demontage des voreilenden Geländers aktiv eine Drehbewegung durchgeführt werden muss. Zudem ist die innenliegende Mechanik relativ aufwendig und beschädigungsanfällig. Zudem muss bei der Montage darauf geachtet werden, dass die obere und untere Klaue am anzubringenden Vertikalrahmen oder Vertikalstiel vollständig angeschlossen und eingerastet ist.The EP 1 571 275 A2 discloses a device for mounting a temporary handrail post with connected telescopic handrails to existing vertical posts of a scaffolding according to the features of the preamble of claim 1. The handrail post has claws with an automatic clamping function, with a continuous rotating shaft being used inside the handrail post, which Actuating units can be rotated and is connected to the claws via a relatively complex mechanism. To connect the vertical standard to the railing post, the operating unit must be actively opened and closed by turning the operating unit. For this purpose, the operating unit is twisted accordingly. A disadvantage of this solution is that a rotary movement has to be actively performed during assembly and disassembly of the leading railing. In addition, the internal mechanism is relatively complex and susceptible to damage. In addition, during assembly, care must be taken to ensure that the upper and lower claws are fully connected and engaged on the vertical frame or vertical post to be attached.

Die DE 103 05 158 A1 offenbart ein voreilendes Geländer, bei dem Geländerholme und Geländerstiele unlösbar miteinander verbunden sind und somit das voreilende Geländer ein Bauteil bildet. Dieses voreilende Geländer wird im Bereich eines Knotenblechs eines bestehenden Geländers und an einen bereits montierten oberen Geländerholm des Gerüsts angeschlossen. Aufgrund von Haltevorrichtungen ist das Geländer dabei in allen Richtungen gesichert. Dieses voreilende Geländer weist keine aussteifende Wirkung auf und dient lediglich als provisorischer Seitenschutz während der Auf- und Abbauphase. Für das Gerüst werden weiterhin Geländer und Diagonalen benötigt. Die Verwendung ist für den Montageablauf nicht zwingend erforderlich.The DE 103 05 158 A1 discloses a leading railing in which railing bars and railing posts are permanently connected to one another and the leading railing thus forms a component. This leading railing is connected in the area of a gusset plate of an existing railing and to an already installed upper railing post of the scaffolding. The railing is secured in all directions thanks to holding devices. This advanced railing has no bracing effect and only serves as temporary side protection during the assembly and dismantling phase. For the scaffolding, railings and diagonal braces will continue to be used needed. Its use is not absolutely necessary for the assembly process.

Des Weiteren ist eine Geländervorrichtung als voreilendes Geländer bekannt, bei dem Geländerstiele und Geländerholme eine Rahmenkonstruktion bilden. Dabei wird bei der Montage das voreilende Geländer an horizontalen Profilen, beispielsweise U-Querriegeln, des Gerüsts eingehängt und anschließend werden die vertikalen Gerüstrohre durch eine Clipverbindung an den Vertikalstielen des Gerüsts befestigt. Dieses voreilende Geländer verbleibt im Gerüst und besitzt aufgrund seiner Rahmenkonstruktion eine aussteifende Wirkung, wodurch beispielsweise Diagonalen und einzelne zusätzliche Geländer, im Gerüst überflüssig werden. Das Geländer ist für den Montageablauf zwingend erforderlich und kann nachträglich nicht demontiert werden. Dieses voreilende Geländer weist relativ viele Verstrebungen auf, was hinsichtlich einer wirtschaftlichen Herstellung und dem Transport nicht optimal ist.Furthermore, a railing device is known as a leading railing, in which the railing posts and railing bars form a frame construction. During assembly, the leading railing is attached to horizontal profiles, for example U-crossbars, of the scaffolding and then the vertical scaffolding tubes are attached to the vertical standards of the scaffolding with a clip connection. This leading railing remains in the scaffolding and has a stiffening effect due to its frame construction, which means that, for example, diagonal braces and individual additional railings in the scaffolding become superfluous. The railing is absolutely necessary for the assembly process and cannot be dismantled later. This leading railing has a relatively large number of struts, which is not optimal in terms of economical production and transport.

Wird Gerüstmaterial an einem Systemgerüst von Hand transportiert geschieht dies in vielen Fällen durch eine Seilwinde. An dieser wir Gerüstmaterial befestigt und so in die entsprechende Gerüstetage gezogen, alternativ werden auch Gerüstaufzüge verwendet. Da der Handlauf und die Knieleiste durch systemintegrierte voreilende Geländer schon montiert sind, muss die Montageperson bei den bekannten voreilenden Geländern das Gerüstmaterial über den Handlauf in das Gerüst hineinziehen, wobei sich die Handlauf in der Regel circa einen Meter über den Gerüstboden befindet, was nicht komfortabel ist.If scaffolding material is transported by hand on a system scaffolding, this is often done using a cable winch. Scaffolding material is attached to this and thus pulled into the corresponding scaffolding floor, alternatively scaffolding lifts are also used. Since the handrail and the knee rail are already installed by means of system-integrated leading railings, the person installing the known leading railings has to pull the scaffolding material into the scaffolding via the handrail, with the handrail usually being about one meter above the scaffolding floor, which is not comfortable is.

In den Fällen, in dem ein bestehendes Gerüst zum Teil abgebaut werden soll ist dieser Abbau unter Verwendung von den bekannten systemintegrierten voreilenden Geländern bisher nicht beziehungsweise nur mit großem Aufwand möglich, da die Stellrahmen oder die Gerüstböden des Systemgerüsts die voreilenden Geländern gegen Abhub sichern.In cases where an existing scaffolding is to be partially dismantled, this dismantling using the known system-integrated leading railings has so far not been possible or only possible with great effort, since the assembly frames or the scaffolding decks of the system scaffolding secure the leading railings against lifting.

In der JP 2008 038588 A als nächstliegender Stand der Technik ist eine Geländervorrichtung für ein Systemgerüst mit einem orthogonalen Bezugsystem mit einer Breitenrichtung, einer Höhenrichtung und einer Querrichtung mit folgenden Merkmalen offenbart:

Dadurch, dass der obere Geländerstab (Handlauf) an schwenkbare innere Vertikalstäbe angeschlossen ist, kann für den Materialtransport in die entsprechende Gerüstetage ein Freiraum geschaffen werden, so dass das Transportmaterial nicht über den Handlauf gehoben werden muss. Dies vereinfacht und erleichtert den Montageaufwand deutlich.Because the upper railing rod (handrail) is connected to swiveling inner vertical rods, free space can be created for the transport of material to the corresponding scaffolding level, so that the transport material does not have to be lifted over the handrail. This simplifies and eases the assembly effort significantly.

Eine besonders bevorzugte Ausgestaltung, die einen hohen Sicherheitsstandard gewährleistet, zeichnet sich dadurch aus, dass nach unten beabstandet zum oberen Geländerstab ein in Breitenrichtung verlaufender unterer Geländerstab - auch Knieleiste genannt - an der rechten und linken inneren Vertikalstrebe angeschlossen ist.A particularly preferred embodiment, which ensures a high safety standard, is characterized in that a lower railing rod running in the width direction—also called a knee rail—is connected to the right and left inner vertical strut spaced downwards from the upper railing rod.

Um den Freiraum bei der Einbringung von Gerüstmaterial in eine Gerüstetage optimal zu gestalten, zeichnet sich eine besonders vorteilhafte Ausgestaltung der erfindungsgemäßen Geländervorrichtung dadurch aus, dass das Höhenniveau der Anordnung der Drehachse beziehungsweise der Drehanschlusseinheiten an dem rechten und linken Vertikalgeländerstiel ausgehend vom unteren Endbereich so groß ist, dass der untere Geländerstab im um 180 ° nach unten umgeklappten Zustand auf oder unter dem Höhenniveau des Gerüstbelags des Systemgerüsts angeordnet ist.In order to optimally design the free space when introducing scaffolding material into a scaffolding level, a particularly advantageous embodiment of the railing device according to the invention is characterized in that the height level of the arrangement of the rotary axis or the rotary connection units on the right and left vertical railing post is so large, starting from the lower end area that the lower railing rod is arranged at or below the height level of the scaffolding deck of the system scaffolding when it is folded down 180°.

Eine konstruktiv besonders einfache Ausgestaltung, die hohe Steifigkeiten und Tragsicherheiten gewährleistet, zeichnet sich dadurch das, dass die rechte und linke Vertikalstrebe als Hohlprofil, Vollprofil, insbesondere als Rechteckprofil, ausgebildet ist.A design that is particularly simple in terms of construction, which ensures high rigidity and structural reliability, is characterized by this that the right and left vertical strut is designed as a hollow profile, solid profile, in particular as a rectangular profile.

In vorteilhafter Art und Weise kann der Anschluss des oberen und/ unteren Geländerstabs an die rechte/linke innere Vertikalstrebe als Schweißverbindung ausgebildet sein.Advantageously, the connection of the upper and/or lower railing rod to the right/left inner vertical strut can be designed as a welded connection.

Eine konstruktiv besonders einfache und eine dauerhaft zuverlässige Funktion gewährleistende vorteilhafte Ausgestaltung zeichnet sich dadurch aus, dass die lösbare Verriegelungseinheit als Schraubeinheit, Federsteckereinheit, Bolzeneinheit, Schlosseinheit oder dergleichen lösbar verriegelbare Einheit ausgebildet ist.An advantageous embodiment that is structurally particularly simple and ensures a permanently reliable function is characterized in that the releasable locking unit is designed as a screw unit, spring connector unit, bolt unit, lock unit or similar releasably lockable unit.

Um in einfacher Art und Weise einen nachträglich Teilabbau des Gerüsts zu ermöglichen, zeichnet sich eine besonders bevorzugte Weiterbildung dadurch aus, dass die Drehanschlusseinheit so ausgebildet ist, dass die rechte/linke innere Vertikalstrebe lösbar anschließbar ist. Dadurch können die rechten und linken Vertikalstreben von den Vertikalgeländerstielen in einfacher Art und Weise gelöst und abgebaut werden.In order to enable subsequent partial dismantling of the scaffolding in a simple manner, a particularly preferred development is characterized in that the rotary connection unit is designed in such a way that the right/left inner vertical strut can be detachably connected. As a result, the right and left vertical struts can be easily detached and removed from the vertical railing posts.

Eine besonders bevorzugte Ausgestaltung, die bezüglich der am Systemgerüst vorhandenen Geometrie besonders vorteilhaft ist und eine hohe Funktionalität gewährleistet, zeichnet sich dadurch aus, dass die Länge der rechten und linken inneren Vertikalstrebe im Bereich zwischen 40 % bis 60 %, insbesondere bei circa 50 %, der Länge des rechten/linken Vertikalgeländerstiels liegt.A particularly preferred embodiment, which is particularly advantageous with regard to the geometry present on the system framework and ensures a high level of functionality, is characterized in that the length of the right and left inner vertical strut is in the range between 40% and 60%, in particular around 50%, the length of the right/left vertical railing post.

Um erhöhten Sicherheitsanforderungen zu genügen, die durch die erfindungsgemäße Geländervorrichtung in einfacher Art und Weise umgesetzt werden können, zeichnet sich eine besonders vorteilhafte Weiterbildung dadurch aus, dass die Geländereinheit eine in Breitenrichtung verlaufende an die rechte und linke Vertikalstrebe angeschlossene Bordbretteinheit aufweist, die sich bei an dem Systemgerüst montierter Geländervorrichtung unmittelbar oberhalb des Höhenniveaus der Gerüstbeläge des Systemgerüst angeordnet ist. Um geometrischen Abmessungen beim Transport der erfindungsgemäßen Geländervorrichtung zu optimieren, zeichnet sich eine vorteilhafte Ausgestaltung dadurch aus, dass der linke und rechte Vertikalgeländerstiel in Höhenrichtung teleskopierbar arretierbar ausgebildet ist oder alternativ dadurch aus, dass der linke und rechte Vertikalgeländerstiel um eine in Breitenrichtung oder Querrichtung verlaufende Drehachse klappbar arretierbar ausgebildet ist, die insbesondere im Wesentlichen auf der Höhe der angeschlossenen Vertikalstreben der Drehachse angeordnet ist.In order to meet increased safety requirements, which can be implemented in a simple manner by the railing device according to the invention, a particularly advantageous development is characterized in that the railing unit has a toe board unit that runs in the width direction and is connected to the right and left vertical struts dem System scaffold mounted railing device is arranged directly above the height level of the scaffold decks of the system scaffold. In order to optimize the geometric dimensions when transporting the railing device according to the invention, an advantageous embodiment is characterized in that the left and right vertical railing posts are designed to be telescopically lockable in the height direction or alternatively in that the left and right vertical railing posts rotate about an axis of rotation running in the width direction or transverse direction is designed to be foldable and lockable, which is arranged in particular essentially at the height of the connected vertical struts of the axis of rotation.

Ein konstruktiv einfache, kompakte und vorteilhafte Ausgestaltung zeichnet sich dadurch aus, dass die rechte und linke Vertikalstrebe parallel unmittelbar innenseitig an dem rechten/linken Vertikalgeländerstiel verlaufen.A structurally simple, compact and advantageous embodiment is characterized in that the right and left vertical struts run parallel directly on the inside of the right/left vertical railing post.

Zur Gewährleistung einer hohen Standsicherheit und Traglast sind die Bauteile der Geländervorrichtung bevorzugt aus Stahl oder Aluminium ausgebildet.To ensure high stability and load capacity, the components of the railing device are preferably made of steel or aluminum.

Ein Verfahren gemäß Anspruch 13 zum Einbringen von zu montierenden Gerüstbauteilen in ein Gerüstfeld einer Gerüstetage eines Systemgerüsts bei dem eine voreilende Geländervorrichtung der oben beschriebenen Art montiert ist, zeichnet sich dadurch aus, dass die lösbare Verriegelungseinheit jeweils am rechten und linken Vertikalgeländerstiel gelöst wird, die Geländereinheit mit rechter und linker Vertikalstrebe und oberem/ unterem Geländerstab um 180 ° um die Drehachse nach unten geschwenkt wird, die Gerüstbauteile in das Gerüstfeld eingebracht werden und anschließend montiert werden, die Geländereinheit um die Drehachse um 180 ° nach oben geschwenkt wird, die Geländereinheit durch Verriegeln der Veriegelungseinheit jeweils an dem rechten und linken Vertikalgeländerstiel angeschlossen wird.A method according to claim 13 for introducing scaffolding components to be assembled into a scaffolding bay of a scaffolding floor of a scaffolding system in which a leading railing device of the type described above is mounted, is characterized in that the releasable locking unit is released on the right and left vertical railing post, the railing unit with the right and left vertical struts and upper/lower handrail rod is pivoted downwards by 180° around the axis of rotation, the scaffolding components are introduced into the scaffolding bay and then assembled, the railing unit is pivoted upwards by 180° around the axis of rotation, the railing unit by locking the locking unit is connected to the right and left vertical railing post.

Durch die neue, systemintegrierte voreilende erfindungsgemäße Geländervorrichtung, die eine nach außen hin umklappbare Geländereinheit (innere Vertikalstreben, Handlauf und Knieleiste) aufweist, bietet einen beweglichen dreiteiligen Seitenschutz mit Handlauf und Knieleiste auf der nächsten Gerüstetage, in einfacher Art und Weise montierbar aus der darunterliegenden Gerüstetage. In dem heruntergeklappten Zustand befindet sich die Knieleiste auf Höhe des Gerüstbodens des Systemgerüst, so dass keine störenden Geländerbauelemente für die Einbringung von zusätzlichem Gerüstmaterial in dieser Gerüstetage vorhanden sind und ein großer Freiraum zur Verfügung steht, was komfortable Montagearbeiten ermöglicht. Um dies zu gewährleisten ist der gelenkige Anschluss um die Drehachse zwischen dem Vertikalgeländerstiel und den Vertikalstreben in entsprechender Höhe platziert.The new, system-integrated, advanced railing device according to the invention, which has a railing unit (inner vertical braces, handrail and knee rail) that can be folded outwards, offers a movable three-part side protection with handrail and knee rail on the next scaffolding level, which can be assembled in a simple manner from the scaffolding level below . When folded down, the knee rail is at the level of the scaffolding floor of the system scaffolding, so that there are no disturbing railing components for the introduction of additional scaffolding material in this scaffolding level and a large amount of free space is available, which enables convenient assembly work. To ensure this, the articulated connection around the axis of rotation between the vertical railing post and the vertical struts is placed at the appropriate height.

Gleichzeitig ist es durch die Ausgestaltung der erfindungsgemäßen voreilenden Geländervorrichtungen möglich, einzelne oder mehrere Gerüstfelder bei Bedarf einfach zu öffnen und wieder verschließen zu können. Der Handlauf und die Knieleiste müssen dazu nicht im Gerüst oder woanders gelagert werden, sondern verbleiben an der heruntergeklappten Einheit im Zusammenspiel mit dem inneren Vertikalstreben.At the same time, the design of the leading railing devices according to the invention makes it possible to easily open and close again one or more scaffolding bays as required. The handrail and the knee rail do not have to be stored in the scaffolding or elsewhere, but remain on the folded down unit in interaction with the inner vertical braces.

Durch das Vorsehen einer Verriegelungseinheit im oberen Endbereich der Vertikalstreben wird ein unbeabsichtigtes Herunterklappen des Seitenschutzes verhindert.The provision of a locking unit in the upper end area of the vertical struts prevents the side protection from being folded down unintentionally.

Die erfindungsgemäße voreilende Geländervorrichtung bietet zusammenfassend unter anderem folgende Vorteile:
Soll Gerüstmaterial im Gerüst transportiert oder eingebracht werden, können Handlauf und Knieleiste einfach nach außen hin heruntergeklappt werden und es wird ein großer Freiraum zur Einbringung des Materials temporär zur Verfügung gestellt.In summary, the leading railing device according to the invention offers the following advantages, among others:
If scaffolding material is to be transported or brought into the scaffolding, the handrail and knee rail can simply be folded down outwards and a large amount of free space is temporarily made available for bringing in the material.

Soll nachträglich ein Teil des Gerüsts abgebaut werden, so ist dies auch möglich. Handlauf und Knieleiste werden dazu in Verbindung mit den inneren Vertikalstreben von der Drehanschlusseinheit komplett gelöst. Dann können die inneren Vertikalstreben, der Handlauf und die Knieleiste sowie ein Vertikalgeländerstiel demontiert werden. Nur der gegenüberliegende Vertikalgeländerstiel bleibt im Systemgerüst, da dieser durch den aufgesetzten Stellrahmen des Systemgerüsts gesichert ist. Dadurch, dass die klappbare Einheit (bestehend aus dem inneren Vertikalstreben, dem Handlauf und der Knieleiste) bevorzugt zusätzlich mit einem integrierten Blech ausgestattet ist, wird ein dreiteiliger Seitenschutz beim Betreten der nächsten Gerüstetage ermöglicht, der hohe Sicherheitsstandards erfüllt.If part of the scaffolding is to be dismantled later, this is also possible. To do this, the handrail and knee rail are completely detached from the rotary connection unit in connection with the inner vertical struts. Then the inner vertical struts, the handrail and the knee rail as well as a vertical railing post can be dismantled. Only the opposite vertical railing post remains in the system scaffold, as this is secured by the assembly frame of the system scaffold. The fact that the foldable unit (consisting of the inner vertical struts, the handrail and the knee rail) is preferably additionally equipped with an integrated sheet metal enables a three-part side protection when entering the next scaffolding level, which meets high safety standards.

Durch die alternativ Ausgestaltung der Vertikalgeländerstiele als ein- und ausklappbare Pfostenrohre wird ermöglicht, dass diese besser und effizienter gestapelt und transportiert werden können, beispielsweise in einer handelsüblichen Rohrpalette.The alternative design of the vertical railing posts as post tubes that can be folded in and out makes it possible for them to be stacked and transported better and more efficiently, for example in a commercially available tube pallet.

Weitere Ausführungsformen und Vorteile der Erfindung ergeben sich durch die in den Ansprüchen ferner aufgeführten Merkmale sowie durch das nachstehend angegebene Ausführungsbeispiel.Further embodiments and advantages of the invention result from the features also listed in the claims and from the exemplary embodiment specified below.

WEGE ZUM AUSFÜHREN DER ERFINDUNGWAYS TO CARRY OUT THE INVENTION

In Fig. 1 ist ein Ausführungsbeispiel einer voreilenden Geländervorrichtung 10 dargestellt. Als orthogonales Bezugssystem ist ein System mit drei orthognalen Achsen, nämlich der Breitenrichtung B, der Querrichtung Q und der Höhenrichtung H angegeben.In 1 an exemplary embodiment of a leading railing device 10 is shown. A system with three orthogonal axes, namely the width direction B, the transverse direction Q and the height direction H, is specified as the orthogonal reference system.

In Höhenrichtung H ist ein rechter Vertikalgeländerstiel 12 und ein linker Vertikalgeländerstiel 14 vorhanden, die in Breitenrichtung B beabstandet vorhanden sind, wobei das Abstandsmaß im Wesentlichen dem Abstandsmaßsystem von Stellrahmen eines von in Fig. 1 nicht näher dargestellten Systemgerüsts im Wesentlichen entspricht.In the height direction H, there is a right-hand vertical railing post 12 and a left-hand vertical railing post 14, which are spaced apart in the width direction B, with the distance dimension essentially corresponding to the distance dimension system of assembly frames of one of in 1 essentially corresponds to the system framework not shown in detail.

Der rechte und linke Vertikalgeländerstiel 12, 14 besitzt nach außen weisende rechte und linke Anschlusseinheiten 18.1, 18.2 auf, die zum lösbaren Anschluss an Vertikalstiele eines Systemgerüsts dienen.The right and left vertical railing post 12, 14 has outward-facing right and left connection units 18.1, 18.2, which are used for detachable connection to vertical posts of a scaffolding system.

Die Vertikalgeländerstiele 12, 14 sind im dargestellten Ausführungsbeispiel als Quadratrohre ausgebildet. Sie können jedoch auch eine andere Profilform aufweisen.The vertical railing posts 12, 14 are designed as square tubes in the illustrated embodiment. However, you can also have a different profile shape.

Zwischen dem rechten und linken Vertikalgeländerstiel 12, 14 ist in Breitenrichtung B verlaufend eine Geländereinheit 40 vorhanden, die eine rechte innere Vertikalstrebe 20 und eine linke innere Vertikalstrebe 22 aufweist, die jeweils an dem rechten Vertikalgeländerstiel 12 beziehungsweise linken Vertikalgeländerstiel 14 angeschlossen sind. Die Vertikalstreben 20, 22 verlaufen parallel zu und anliegend vom oberen Endbereich des rechten Vertikalgeländerstiels 12 beziehungsweise linken Vertikalgeländerstiels 14 nach unten mit einer Länge L, die im dargestellten Ausführungsbeispiel im Wesentlichen circa 50 % der Gesamtlänge der Vertikalgeländerstiele 12, 14 beträgt.Between the right and left vertical railing posts 12, 14, there is a railing unit 40 running in the width direction B, which has a right inner vertical brace 20 and a left inner vertical brace 22, which are connected to the right vertical railing post 12 and left vertical railing post 14, respectively. The vertical struts 20, 22 run parallel to and adjacent to the upper end area of the right vertical railing post 12 or left vertical railing post 14 downwards with a length L, which in the illustrated embodiment is essentially approximately 50% of the total length of the vertical railing posts 12, 14.

Im oberen Endbereich der rechten inneren Vertikalstrebe 20 und der linken inneren Vertikalstrebe 22 ist in Breitenrichtung B ein oberer Geländerstab 16 innenseitig angeschlossen, der als Handlauf dient. In einem Abstand A unterhalb des oberen Geländerstabs 16 ist ein unterer Geländerstab 24 in Breitenrichtung B verlaufend innenseitig an die rechte innere Vertikalstrebe 20 und linke innere Vertikalstrebe 22 angeschlossen. Der untere Geländerstab dient als Knieleiste.In the upper end area of the right inner vertical strut 20 and the left inner vertical strut 22, an upper railing rod 16 is connected on the inside in the width direction B and serves as a handrail. At a distance A below the upper railing rod 16 , a lower railing rod 24 running in the width direction B is connected on the inside to the right inner vertical strut 20 and left inner vertical strut 22 . The lower baluster serves as a knee rail.

Im dargestellten Ausführungsbeispiel ist der obere und untere Geländerstab 16, 24 an die rechte innere Vertikalstrebe 20 beziehungsweise linke innere Vertikalstrebe 22 angeschweißt.In the illustrated embodiment, the upper and lower railing rods 16, 24 are welded to the right-hand inner vertical strut 20 and left-hand inner vertical strut 22, respectively.

Der oberen Geländerstab 16 und der untere Geländerstab 24 sind im Ausführungsbeispiel als Rundrohrprofile ausgebildet.The upper railing rod 16 and the lower railing rod 24 are designed as round tube profiles in the exemplary embodiment.

Die rechte innere Vertikalstrebe 20 und die linke innere Vertikalstrebe 22 sind im Ausführungsbeispiel als Rechteckvollprofile ausgebildet, deren Breite im Wesentlichen der Breite der Vertikalgeländerstiele 12, 14 entspricht.In the exemplary embodiment, the right-hand inner vertical strut 20 and the left-hand inner vertical strut 22 are designed as solid rectangular profiles, the width of which essentially corresponds to the width of the vertical railing posts 12 , 14 .

Zwischen dem oberen Geländerstab 16 und dem unteren Geländerstab 24 ist in Breitenrichtung B in etwa der Mitte ein Abstandspfosten 26 angeordnet.Between the upper railing rod 16 and the lower railing rod 24 a spacer post 26 is arranged in the width direction B approximately in the middle.

Der untere Endbereich der rechten inneren Vertikalstrebe 20 und der linken inneren Vertikalstrebe 22 ist über eine Drehanschlusseinheit 32 an den rechten beziehungsweise linken Vertikalgeländerstiel 12, 14 angeschlossen. Die Drehanschlusseinheit 32 ist lösbar ausgebildet, so dass die Geländereinheit 40 bedarfsweise gelöst werden kann. Die Drehanschlusseinheit 32 bewirkt es, dass die Geländereinheit 40 beziehungsweise die inneren Vertikalstreben 20, 22 um eine Drehachse 30 schwenkbar vorhanden sind, die in Breitenrichtung B verläuft. Dadurch kann die gesamte Geländereinheit 40 um die Drehachse 30 beispielsweise nach unten um 180 ° geklappt werden.The lower end area of the right inner vertical strut 20 and the left inner vertical strut 22 is connected to the right and left vertical railing posts 12, 14 via a rotary connection unit 32, respectively. The rotary connector unit 32 is designed to be detachable, so that the railing unit 40 can be detached as required. The rotary connection unit 32 causes the railing unit 40 or the inner vertical struts 20, 22 to be pivotable about an axis of rotation 30 that runs in the width direction B. As a result, the entire railing unit 40 can be folded down about the axis of rotation 30 by 180°, for example.

Um ein unbeabsichtigtes Umklappen der Geländereinheit 40 zu verhindern, ist im oberen Endbereich der linken und rechten Vertikalstrebe 20, 22 eine lösbar arretierbare Verriegelungseinheit 34 zwischen der inneren Vertikalstrebe 20 beziehungsweise 22 und dem Vertikalgeländerstiel 12, 14 vorhanden.In order to prevent the railing unit 40 from accidentally folding over, there is a releasably lockable locking unit 34 between the inner vertical brace 20 or 22 and the vertical railing post 12, 14 in the upper end region of the left and right vertical struts 20, 22.

Dadurch, dass sowohl die Verriegelungseinheit 34 als auch die Drehanschlusseinheit 32 als lösbare Einheiten ausgebildet sind, kann die Geländereinheit 40 als Ganzes bedarfsweise entfernt werden.Due to the fact that both the locking unit 34 and the rotary connection unit 32 are designed as detachable units, the railing unit 40 can be removed as a whole if necessary.

Durch Lösen der Verriegelungseinheit 34 kann die Geländereinheit 40 bedarfsweise um 180 ° nach unten geschwenkt werden.By releasing the locking unit 34, the railing unit 40 can be pivoted downwards by 180°, if necessary.

Zusätzlich ist in Fig. 1 mit dem Bezugszeichen HB noch das Höhenniveau angegeben, auf dem sich die Gerüstbeläge eines in Fig. 1 nicht näher dargestellten Systemgerüsts befinden, sofern die Geländervorrichtung 10 an dem Systemgerüst angeschlossen ist.Additionally is in 1 with the reference HB the height level at which the scaffold decks of an in 1 not System scaffold shown in more detail are located if the railing device 10 is connected to the system scaffold.

In Fig. 1 ist ergänzend noch das Höhenniveau H1 angegeben, das die Anordnung der Drehanschlusseinheit 32 beziehungsweise der Drehachse in Bezug auf den unteren Endbereich des rechten beziehungsweise linken Vertikalgeländerstiels 12, 14 darstellt. Da Höhenniveau H1 ist dabei so gewählt, dass bei um 180 ° umgeklappter Geländereinheit 40 sich der untere Geländerstab 24 auf dem Höhenniveau HB oder knapp unterhalb des Höhenniveaus HB der Gerüstbelege des Systemgerüsts befinden, so dass sich ein optimaler Freiraum im heruntergeklappten Zustand der Geländereinheit 40 in dem jeweiligen Gerüstfeld zur Verfügung steht.In 1 the height level H1 is additionally specified, which represents the arrangement of the rotary connection unit 32 or the rotary axis in relation to the lower end region of the right or left vertical railing post 12, 14. The height level H1 is selected in such a way that when the railing unit 40 is folded down by 180°, the lower railing rod 24 is at the height level HB or just below the height level HB of the scaffolding covers of the system scaffolding, so that there is optimum free space when the railing unit 40 is folded down is available for the respective scaffold bay.

Durch die dargestellte Konstruktion kann die Geländereinheit 40 bedarfsweise durch Lösung der Verriegelungseinheiten 34 um 180 ° in einer Drehrichtung D nach unten umgeklappt werden, was in Fig. 8 und 9 am Systemgerüst dargestellt ist.Due to the construction shown, the railing unit 40 can, if necessary, be folded down by 180° in a direction of rotation D by releasing the locking units 34, which in 8 and 9 shown on the system framework.

Ein Gerüstfeld 72 wird durch zwei in Breitenrichtung B mit dem Systemmaß des Systemgerüsts 50 angeordnete Stellrahmen 70 definiert.In 4 a section of a system scaffolding 50 with a lower scaffolding floor 52 is shown at the beginning of the assembly of a railing device 10 . A scaffold bay 72 is defined by two positioning frames 70 arranged in the width direction B with the system dimensions of the system scaffold 50 .

Die Stellrahmen 70 weisen zwei in Querrichtung Q in einem Systemmaß angeordnete Vertikalstiele 58 auf, die in ihrem oberen Endbereich mit einem Querriegel 60 miteinander verbunden sind. Überstehend sind im oberen Endbereich der Vertikalstiele 58 Rohrverbinder 68 angeordnet, auf die für eine obere Gerüstetage weitere Stellrahmen 70 aufgesteckt werden können.The positioning frames 70 have two vertical posts 58 which are arranged in a system dimension in the transverse direction Q and which are connected to one another in their upper end region with a cross bar 60 . The vertical posts 58 protrude in the upper end area Pipe connectors 68 are arranged, onto which additional setting frames 70 can be attached for an upper scaffold floor.

Beim Montagevorgang wird zunächst die von unten her zweite rechte Anschlusseinheit 18.1 an dem im Bereich des Anschlussquerriegels 60 an den Vertikalstiel 58 des Stellrahmens 70 von oben her eingehängt. Dann wird die Geländervorrichtung 10 in Schwenkrichtung S verschwenkt, so dass auch die von unten her zweite Anschlusseinheit 18 des linken Vertikalgeländerstiels 14 im Bereich des Anschlusses des Querriegels 60 und des Vertikalstiels 50 des linken Stellrahmens 70 eingehängt werden kann. Dadurch kommen die unteren Anschlusseinheiten 18.1 beziehungsweise 18.2 des rechten beziehungsweise linken Vertikalgeländerstiels 12, 14 mit dem entsprechenden Vertikalstiel 58 des Stellrahmens 70 in Formschluss.During the assembly process, the second right connection unit 18.1 from below is first hung from above on the vertical post 58 of the positioning frame 70 in the area of the connection cross bar 60. The railing device 10 is then pivoted in the pivoting direction S, so that the second connection unit 18 of the left vertical railing post 14 from below can also be hung in the area of the connection of the cross bar 60 and the vertical post 50 of the left positioning frame 70 . As a result, the lower connection units 18.1 or 18.2 of the right or left vertical railing post 12, 14 come into positive contact with the corresponding vertical post 58 of the positioning frame 70.

Dieser Zustand ist in Fig. 5 dargestellt.This state is in figure 5 shown.

Die obere rechte Anschlusseinheit 18 des rechten Vertikalgeländerstiels 12 ist außenseitig auf dem Höhenniveau des unteren Geländerstabs 24 angeschlossen. Die obere linke Anschlusseinheit 18 des linken Vertikalgeländerstiels 14 ist außenseitig im Wesentlichen auf dem Höhennivau des oberen Geländerstabs 16 angeordnet. Die obere linke und rechte Anschlusseinheit 18.1, 18.2 dient dazu, dass diese bei weiteren auf die Stellrahmen 70 aufgestellten Stellrahmen einer weiteren Gerüstetage mit dem an den Vertikalstiele 58 der Stellrahmen 70 innenseitig vorhandenen Geländeranschlusseinheiten 62 in Eingriff kommen und damit eine zusätzliche Sicherung bilden.The upper right connection unit 18 of the right vertical railing post 12 is connected on the outside at the level of the lower railing rod 24 . The upper left connection unit 18 of the left vertical railing post 14 is arranged on the outside essentially at the level of the upper railing rod 16 . The upper left and right connection units 18.1, 18.2 are used to ensure that, when additional frames of another scaffolding level are set up on the assembly frames 70, they come into engagement with the railing connection units 62 on the inside of the vertical posts 58 of the assembly frames 70 and thus form an additional safeguard.

Die Fig. 6 zeigt einen Ausschnitt aus einem Systemgerüst 50 mit Darstellung von drei Gerüstfeldern 72, 74, 76 einer unteren Gerüstetage 52 mit montierten Geländervorrichtungen 10.The 6 shows a section of a scaffolding system 50 showing three scaffolding bays 72, 74, 76 of a lower scaffolding floor 52 with mounted railing devices 10.

Ausgehend von dem Montagezustand gemäß Fig. 6 werden im nächsten Montageschritt Gerüstbeläge auf die Querriegel 60 der Stellrahmen 70 eingehängt und auf die jeweiligen Stellrahmen 70 weitere Stellrahmen 70 aufgesteckt, so dass eine weitere Gerüstetage 54 entsteht, die bereits durch die Montage von der unteren Gerüstetage 52 aus erfolgte Montage der Geländervorrichtungen 10 einen zuverlässigen Seitenschutz aufweist.Based on the assembly state according to 6 In the next assembly step, scaffolding decks are hung on the cross bars 60 of the assembly frames 70 and on the respective assembly frames 70 further setting frames 70 are plugged on, so that a further scaffolding level 54 is created, which already has reliable side protection as a result of the assembly of the lower scaffolding level 52 from the assembly of the railing devices 10 .

Die Fig. 8 zeigt einen Ausschnitt eines Gerüstsystems gemäß Fig. 7, bei dem auf der oberen Etage 54 im mittleren Gerüstfeld 72 die Geländereinheit 40 um 180 ° nach unten geklappt ist, um Freiraum zu schaffen, damit weitere Gerüstteile zur weiteren Montage des Systemgerüsts komfortabel und problemlos eingebracht werden können.The 8 shows a section of a scaffolding system according to 7 , in which the railing unit 40 is folded down by 180° in the middle scaffolding field 72 on the upper floor 54 in order to create free space so that further scaffolding parts for further assembly of the system scaffolding can be brought in comfortably and easily.

Die Fig. 9 zeigt einen Ausschnitt aus einem Systemgerüst mit insgesamt drei Gerüstetagen 52, 54, 56 und drei Gerüstfeldern 72, 74, 76, bei dem im mittleren Gerüstfeld 72 in der oberen Gerüstetage 56 die Geländereinheit 40 um 180° nach unten geklappt ist, in einem Montagezustand, in dem über zwei Montagepersonen 44 mit Hilfe eines Seilzugs 78 eine zusätzliche Geländervorrichtung 10.1 zur weiteren Montage für eine darüber angeordnete Gerüstetage eingebracht wird. Es ist deutlich zu erkennen, dass durch die herunter geklappte Geländereinheit 40 ein großer Freiraum entsteht, der eine komfortable, einfache und sichere Einbringung der weiteren Geländervorrichtung 10.1 zum Zwecke der weiteren Montage ermöglicht, ohne dass die weitere Geländervorrichtung 10.1 über den Handlauf der Geländereinheit 40 angehoben werden muss.The 9 shows a section of a system scaffolding with a total of three scaffolding floors 52, 54, 56 and three scaffolding bays 72, 74, 76, in which the railing unit 40 in the middle scaffolding bay 72 in the upper scaffolding floor 56 is folded down by 180°, in an assembled state, in which an additional railing device 10.1 for further assembly for a scaffolding level arranged above it is brought in by two assembly workers 44 with the aid of a cable pull 78. It can be clearly seen that the railing unit 40 that is folded down creates a large amount of free space, which enables the additional railing device 10.1 to be brought in conveniently, easily and safely for the purpose of further assembly, without the additional railing device 10.1 being lifted over the handrail of the railing unit 40 must become.
