Abstract

A dismantlable, multi-story facade scaffold is formed of at least four vertical support elements and floor plates and railing elements which are mounted thereto. An additional scaffold story is erected by coupling an additional vertical support element to an already existing one and pivotally attaching one end of a railing element thereto at a location above where the floor plate for the next story will be placed. The other end of that railing element is pivotally attached to another vertical support element. This other vertical support element is then raised, thereby pivotally moving the rail element relative to the respective vertical support element until the rail element is in a horizontal position and the vertical support element is in the vertical position. The other vertical support element is now attached to the upper end of a corresponding vertical support of the lower scaffold story. Thereafter the floor plate for the additional scaffold story is installed so that a worker stepping on the floor plate of the higher story is protected from the very beginning against falling off. The connections between the ends of the railing and the respective vertical support elements are disengageable when they are in relatively inclined positions and become locked when the railing is perpendicular to the support elements. The scaffold is dismantled by reversing this procedure.

Description

Die Erfindung betrifft ein zerlegbares-Fassadengerüst nach dem Oberbegriff des Patentanspruchs 1 und ein Verfahren zum Montieren bzw Demontieren eines derartigen Fassadengerüstes nach den Oberbegriffen der Patentansprüche 28 und 29.The invention relates to a dismountable facade scaffold according to the preamble of patent claim 1 and a method for mounting or dismounting of such a facade scaffold according to the preambles of claims 28 and 29.

Derartige Fassadengerüste, bei denen die Vertikalstützen aus voneinander trennbaren Stützelementen bestehen (CH-A-658878; GB-A-0276487), werden in großem Umfange dazu verwendet, an der Fassade eines Gebäudes aufgestellt zu werden, um dort Außenarbeiten, z.B. einen Anstrich vornehmen zu können.Such facade scaffolds, in which the vertical supports consist of separable support elements (CH-A-658878; GB-A-0276487), are widely used to be erected on the facade of a building for external work, e.g. to be able to paint.

Aufgebaut werden derartige Fassadengerüste im allgemeinen dadurch, daß die einzelnen Gerüstebenen sukzessive errichtet werden, wobei die einzelnen Stützelemente der Vertikalstützen einer ersten Gerüstebene in der Regel jeweils kurz oberhalb einer zu einer zweiten, darüber liegenden Gerüstebene gehörenden Bodenplatte enden. Dieses obere Ende der Stützelemente wird dann vom Monteur mit dem unteren Ende der Stützelemente für die zweite Gerüstebene insbesondere mittels einer Steckverbindung gekoppelt.Such facade scaffoldings are generally constructed by successively erecting the individual scaffolding levels, with the individual support elements of the vertical supports of a first scaffolding level generally terminating shortly above a floor slab belonging to a second scaffolding level above it. This upper end of the support elements is then coupled by the fitter with the lower end of the support elements for the second framework level, in particular by means of a plug connection.

Anschließend werden in derjenigen (der zweiten) Gerüstebene, in der sich der Monteur während des zuletzt geschilderten Arbeitsschritts befindet, ein oder mehrere im wesentlichen horizontal verlaufende Geländerelemente an den Stützelementen angebracht. Diese Geländerelemente dienen zur Verringerung der Absturzgefahr.Subsequently, one or more substantially horizontally extending railing elements are attached to the support elements in that (the second) scaffolding level in which the installer is located during the last-mentioned work step. These railing elements are used to reduce the risk of falling.

Nachdem alle Geländerelemente für diese zweite Gerüstebene montiert sind, wird die zur über der zweiten Gerüstebene liegenden dritten Gerüstebene gehörende Bodenplatte vom Monteur über Kopf mit den zuvor angebrachten Stützelementen gekoppelt.After all railing elements have been mounted for this second framework level, the base plate belonging to the third framework level lying above the second framework level is coupled by the mechanic overhead with the previously attached support elements.

Schließlich wird das Gerüst beim Errichten der einzelnen Ebenen zusätzlich noch mit Quer- und/oder Diagonalstreben stabilisiert.Finally, the framework is stabilized when erecting the individual levels additionally with transverse and / or diagonal struts.

Bei bekannten Fassadengerüsten der genannten Art ist es von Nachteil, daß der Monteur sowohl während des Aufstellens der Stützelemente für die nächste Gerüstebene als auch bei der Montage der Geländerelemente für diese nächste Gerüstebene ohne jeglichen Seitenschutz bzw. ohne jegliches Seitengeländer arbeiten muß. Dies bedingt eine erhebliche Unfallgefahr.In known facade scaffolds of the type mentioned, it is disadvantageous that the fitter must work both during the erection of the support elements for the next scaffolding level and during assembly of the railing elements for this next scaffold level without any side protection or without any side railing. This causes a considerable risk of accidents.

Um dem zu begegnen, ist es bereits bekanntgeworden (FR-A-2336532), das Geländer einer neu zu errichtenden Etage von der bereits fertiggestellten Etage aus zu montieren und erst dann die zu der nächsten Etage gehörende Bodenplatte auf den bereits fertiggestellten Teil des Gerüstes aufzulegen, so daß ein die neue Bodenplatte betretender Arbeiter schon durch das zuvor montierte Geländer gegen Absturz geschützt ist. Die Vorabmontage des Geländers der nächsten Etage erfordert es, daß sich von beiden Seiten des Geländers nach unten Vertikalstreben erstrecken, die zunächst mit dem bereits fertiggestellten Teil des Gerüstes und später auch mit den Stützelementen der folgenden Etage verbunden werden.To counter this, it has already become known (FR-A-2336532) to mount the railing of a new floor to be built from the already completed floor and only then hang the belonging to the next floor floor panel on the already completed part of the scaffold so that a worker entering the new floorboard is already protected against falling by the previously mounted railing. The pre-assembly of the railing of the next floor requires vertical struts extending from both sides of the railing, which are first connected to the already completed part of the framework and later also to the support elements of the following floor.

Auch bei einem weiteren bekannten, gattungsgemäßen zerlegbaren Fassadengerüst (FR-A-2516141) sind an einem Ende des Geländers nach unten vorstehende Streben vorgesehen, mittels denen das am anderen Ende an eine Vertikalstütze gehängte Geländer zur nächsten Etage nach oben geschwenkt und dann an einem bereits vorher errichteten vertikalen Stützelement befestigt wird.Also in another known, generic dismantled facade scaffolding (FR-A-2516141) are provided at one end of the railing downwardly projecting struts, by means of which at the other end hung on a vertical support railing pivoted to the next floor upwards and then to an already previously erected vertical support element is attached.

Die bekannten Lösungen erfordern also jeweils zusätzliche, sich nach unten erstreckende Vertikalsttitzen, um ein Geländerelement zur nächsten Etage hochzubewegen und an den vertikalen Stützelementen des Gerüstes zu befestigen.Thus, the known solutions each require additional, downwardly extending vertical tips to move up a railing element to the next floor and attach it to the vertical support elements of the framework.

Die Aufgabe der Erfindung besteht darin, ein zerlegbares Fassadengerüst sowie ein Verfahren zum Montieren bzw. Demontieren eines derartigen Fassadengerüstes der eingangs genannten Art bereitzustellen, bei dem nicht nur die Unfallgefahr während des Montierens bzw Demontierens auf ein Minimum reduziert ist, sondern die Montage/Demontage auf einfache Weise wirtschaftlich durchführbar ist.The object of the invention is to provide a collapsible facade scaffold and a method for mounting or dismounting of such a facade scaffold of the type mentioned, in which not only the risk of accidents during assembly or disassembly is reduced to a minimum, but the assembly / disassembly simple way is economically feasible.

Zur Lösung dieser Aufgabe sind die Merkmale der kennzeichnenden Teile der Ansprüche 1, 28 bzw. 29 vorgesehen.To solve this problem, the features of the characterizing parts of claims 1, 28 and 29 are provided.

Erfindungsgemäß werden also die mit einem Ende mit einem bereits montierten Stützelement schwenkbar verbundenen Geländerelemente mit dem anderen Ende mit einem noch nicht montierten weiteren Stützelement gekoppelt, worauf das weitere Stützelement unter einer in eine horizontale Position erfolgenden Verschwenkung des Geländerelementes angehoben und auf das zugeordnete Stützelement der bereits fertiggestellten Etage aufgesetzt wird. Zum Hochschwenken des Geländerelements wird also keine zusätzliche Vertikalstütze, sondern das später einen Bestandteil des Gerüstes bildende Stützelement selbst verwendet.According to the invention, therefore, the one hand with an already mounted support member pivotally connected railing elements are coupled to the other end with a not yet mounted another support element, whereupon the further support element raised in a horizontal position taking place pivoting of the railing element and the associated support element already finished floor is placed. For pivoting the railing element so no additional vertical support, but the later part of the framework forming support element itself is used.

Vorteilhafte Weiterbildungen des erfindungsgemäßen Fassadengerüstes entnimmt man den Patentansprüchen 2 bis 27.Advantageous developments of the facade scaffold invention takes one of the claims 2 to 27.

Das Montieren bzw. Demontieren eines erfindungsgemäßen zerlegbaren Fassadengerüstes wird bevorzugt gemäß den Patentansprüchen 28 bzw. 29 vorgenommen.The mounting or demounting of a dismountable facade scaffold according to the invention is preferably carried out according to claims 28 and 29, respectively.

Ein besonders einfaches Montieren und Demontieren des erfindungsgemäßen Gerüsts wird erfindungsgemäß dadurch ermöglicht, daß ein lediglich einseitig an einem Stützelement fixiertes Geländerelement um zumindest eine im wesentlichen horizontal durch die Kopplungsstelle zwischen Stützelement und Geländerelement verlaufende Achse schwenkbar ist. So kann das Geländerelement schwenkbar an einem bereits montierten Stützelement angebracht werden und anschließend mit Hilfe eines weiteren, noch zu montierenden Stützelements in seine endgültige Horizontalposition nach oben verschwenkt werden.A particularly simple assembly and disassembly of the scaffold according to the invention is made possible in that a only one side fixed to a support railing element is pivotable about at least one substantially horizontally extending through the coupling point between the support element and railing element axis. Thus, the railing element can be pivotally mounted on an already mounted support member and then with the help of another, yet to be mounted support member in its final horizontal position be swiveled upwards.

Es ist jedoch ebenso möglich, daß die Geländerelemente mit einem Ende über eine Gelenkverbindung fest mit einem Stützelement verbunden sind, so daß diese Verbindung vom Monteur weder hergestellt noch gelöst werden muß, da Geländerelement und Stützelement eine Einheit bilden. Diese Ausführungsform hat den Vorteil, daß die Anzahl der beim Montieren bzw. Demontieren zu bewegenden Einzelteile reduziert wird.However, it is also possible that the railing elements are connected at one end via a hinge connection fixed to a support element, so that this connection must not be made by the installer nor solved because railing element and support element form a unit. This embodiment has the advantage that the number of items to be moved during mounting or dismounting is reduced.

Zum Erreichen des erfindungsgemäßen Vorteilsträgt bei, daß die Stoßstellen der Stützelemente der Vertikalstützen nicht mehr wie beim Stand der Technik kurz oberhalb der Bodenplatten, sondern soweit oberhalb der Bodenplatten vorgesehen werden, daß am oberen Endbereich der Stützelemente ein Geländerelement in ausreichendem Abstand zur Befestigungsposition der Bodenplatte montiert werden kann. So wird es möglich, bei der Montage die Geländerelemente einer Gerüstebene vor den zu dieser Gerüstebene gehörenden Bodenplatten zu montieren. In analoger Weise wird es bei der Demontage des Gerüsts möglich, die Bodenplatten vor den Geländerelementen zu demontieren, so daß es nicht vorkommen kann, daß ein Monteur sich auf einer Bodenplatte bewegt, deren zugehörige Geländerelemente bereits demontiert sind.To achieve the advantage according to the invention contributes to the fact that the joints of the support elements of the vertical supports are not provided as above the bottom plates, but so far above the bottom plates as in the prior art that mounted at the upper end of the support elements, a railing element at a sufficient distance from the mounting position of the bottom plate can be. Thus, it becomes possible to mount during assembly the railing elements of a scaffold level in front of the belonging to this framework level floor panels. In an analogous manner, it becomes possible during disassembly of the scaffolding to dismantle the floor panels in front of the railing elements, so that it can not happen that a mechanic moves on a base plate whose associated railing elements are already dismantled.

Der durch die Erfindung geschaffene und stets vorhandene Seitenschutz ist insbesondere deshalb vorteilhaft, da beim Montieren und Demontieren ständig Einzelteile des Gerüsts vom Monteur aufgenommen oder abgegeben werden müssen, wobei sich der Monteur zwangsläufig etwas nach außen lehnen muß, was ohne Seitenschutz eine nicht zu vemachlässigende Absturzgefahr bedingen würde. Zu berücksichtigen ist auch, daß Montage und Demontage auch bei ungünstiger Witterung, beispielsweise bei starkem Wind oder glattgefrorenen Bodenplatten erfolgen. In diesem Fall der zusätzlich erhöhten Absturzgefahr wirkt sich der erfindungsgemäße Seitenschutz besonders vorteilhaft aus.The created by the invention and always present side protection is particularly advantageous because when assembling and disassembling constantly parts of the scaffold must be picked up or delivered by the fitter, with the fitter inevitably has to lean slightly outwards, which without side protection a not to vemachlässigende danger of falling would require. It should also be considered that assembly and disassembly even in unfavorable weather, for example, in strong winds or smooth frozen floor panels. In this case, the additionally increased risk of falling, the side protection according to the invention has a particularly advantageous effect.

Die Montage eines erfindungsgemäßen Gerüsts kann beispielsweise folgendermaßen bewerkstelligt werden:The assembly of a scaffold according to the invention can be accomplished, for example, as follows:

Ein Geländerelement wird mit einem Ende mit einem bereits montierten Stützelement im Bereich der zu errichtenden Gerüstebene gekoppelt, wobei zu diesem Zeitpunkt die Bodenplatte der zu errichtenden Gerüstebene noch nicht montiert ist. Anschließend wird das andere Ende des Geländerelements mit einem noch nicht montierten weiteren Stützelement gekoppelt, woraufhin das weitere Stützelement unter Verschwenkung des Geländerelements montiert wird. Durch die Montage des weiteren Stützelements wird das Geländerelement also in seine endgültige Horizontalposition in der zu errichtenden Gerüstebene gebracht, wobei auf die beschriebene Art in einfacher Weise erreicht werden kann, daß das Geländerelement in einer Höhe montierbar ist, die vom Monteur direkt mit seinen Armen aufgrund der noch nicht montierten Bodenplatte nicht erreichbar ist.A railing element is coupled at one end to an already mounted support element in the region of the scaffold plane to be erected, at which time the base plate of the scaffolding plane to be erected is not yet mounted. Subsequently, the other end of the railing element is coupled with a not yet mounted further support element, after which the further support element is mounted under pivoting of the railing element. By mounting the other support element, the railing element is thus brought into its final horizontal position in the scaffolding level to be built, which can be achieved in the manner described in a simple manner that the railing element is mounted at a height that the fitter directly with his arms due the unassembled bottom plate is not accessible.

Nach der auf die beschriebene Weise erfolgten Montage des Geländerelements kann dann die zu der errichtenden Gerüstebene gehörende Bodenplatte montiert werden, die nachfolgend vom Monteur auch betreten werden kann, da das zugehörige Geländerelement bereits vor der Bodenplatte montiert war.After done in the manner described mounting the railing element then belonging to the erecting scaffold plane floor plate can be mounted, which can also be entered by the fitter also later, since the associated railing element was already mounted in front of the bottom plate.

Bei der Demontage kann in entsprechend umgekehrter Reihenfolge vorgegangen werden.When disassembling can be proceeded in the reverse order.

Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Gerüsts beträgt der Abstand zwischen der für das Geländerelement vorgesehenen Befestigungsposition eines Stützelements und der für die Bodenplatte vorgesehenen Befestigungsposition desselben Stützelements zwischen 70 cm und 130 cm, insbesondere ungefähr 100 cm.In a preferred embodiment of the scaffold according to the invention, the distance between the intended for the railing element attachment position of a support member and provided for the bottom plate mounting position of the same support member between 70 cm and 130 cm, in particular about 100 cm.

Bei aufgestelltem Gerüst kann sich das Stützelement über die für die Bodenplatte vorgesehene Befestigungsposition hinaus beispielsweise über eine Länge zwischen 60 cm und 120 cm, insbesondere über ungefähr 90 cm nach unten erstrecken.When the scaffold is erected, the support element may extend beyond the fastening position provided for the base plate, for example over a length of between 60 cm and 120 cm, in particular over approximately 90 cm.

Die vorstehend genannten Maße gewährleisten, daß das Geländerelement jeweils in ausreichend großer Höhe über den zu montierenden Bodenplatten befestigt werden kann, so daß ein wirksamer Seitenschutz, beispielsweise in einer Höhe von 100 cm über der jeweiligen Bodenplatte erreicht wird.The above dimensions ensure that the railing element can each be secured at a sufficiently high height above the floor panels to be mounted, so that an effective side protection, for example, is achieved at a height of 100 cm above the respective bottom plate.

Bei einer möglichen Ausführungsform der Erfindung wird die Montage dadurch vereinfacht, daß die Geländerelemente an den dafür vorgesehenen Befestigungspositionen der Stützelemente ohne Verwendung eines Werkzeugs anbringbar sind. Das beim Stand der Technik oftmals nötige Einschlagen eines Keils mittels eines Hammers wird somit überflüssig.In a possible embodiment of the invention, the assembly is simplified in that the railing elements are attached to the designated mounting positions of the support elements without the use of a tool. The often required in the prior art striking a wedge by means of a hammer is thus superfluous.

Bevorzugt wird die Kopplung zwischen Geländerelement und Stützelement derart ausgestaltet, daß sie auch ohne Verwendung eines Werkzeugs wieder lösbar ist. Auf diese Weise wird die Demontage vereinfacht und beschleunigt.Preferably, the coupling between railing element and support element is designed such that it is releasable again without the use of a tool. In this way, the dismantling is simplified and accelerated.

Da bei Fassadengertisten in der Regel mehrere Vertikaleinheiten mit in einer Ebene aneinander angrenzenden Bodenplatten nebeneinander aufgestellt werden, ist es sinnvoll, die Kopplung zwischen Geländerelementen und Stützelementen so auszubilden, daß an einer Befestigungsposition eines Stützelements zwei Geländerelemente befestigbar sind, die sich dann horizontal jeweils in entgegengesetzte Richtungen erstrekken.As with Fassenggtisten usually several vertical units are placed side by side in a plane adjacent floor panels, it makes sense, the coupling between railing elements and support elements in such a way that at a mounting position of a support element two railing elements are fastened, which then horizontally in opposite directions Reach directions.

Eine besonders einfache Kopplung zwischen Geländerelementen und Stützelementen ergibt sich dann, wenn die Geländerelemente an den dafür vorgesehenen Befestigungspositionen der Stützelemente einhängbar sind. Dabei ist es wiederum von Vorteil, wenn die Hängeverbindung mit einer Sicherung gegen unbeabsichtigtes Lösen ausgestattet ist, um auf diese Weise sicherzustellen, daß bei Ausübung einer horizontal gerichteten Kraft auf ein Geländerelement, wie sie beispielsweise bei einem Anlehnen des Monteurs an das Geländerelement auftritt, das Geländerelement zuverlässig mit dem Stützelement verbunden ist.A particularly simple coupling between railing elements and support elements is obtained when the railing elements can be suspended at the designated mounting positions of the support elements. It is again advantageous if the suspension connection is equipped with a safeguard against unintentional loosening, in order to ensure in this way that upon exercise of a horizontally directed force on a railing element, as they For example, occurs when leaning the fitter to the railing element, the railing element is reliably connected to the support element.

Die genannte Sicherung ist vorzugsweise so ausgestaltet, daß sie allein durch die Kopplung von Geländerelement und Stützelement erreicht wird, ohne daß hierfür gesonderte Einrichtungen betätigt oder vom Monteur zusätzliche Handgriffe ausgeführt werden müssen.Said fuse is preferably designed so that it is achieved solely by the coupling of railing element and support element, without the need for separate facilities operated or additional operations must be performed by the fitter.

Vorzugsweise wird die Hängeverbindung realisiert durch ein sich im wesentlichen senkrecht zum Stützelement erstreckendes und fest mit diesem verbundenes Ansatzstück sowie eine am Endbereich des Geländerelements vorgesehene und mit dem Ansatzstück koppelbare Lasche. Vorteilhaft bei dieser Ausführungsform ist, daß weder am Geländerelement noch am Stützelement bewegliche Teile vorgesehen werden müssen.Preferably, the suspension connection is realized by a substantially perpendicular to the support member extending and firmly connected thereto end piece and provided on the end portion of the railing element and can be coupled with the extension lug. An advantage of this embodiment is that neither on the railing element nor on the support element moving parts must be provided.

Das Ansatzstück ist vorzugsweise als Stanzteil ausgeführt, welches beispielsweise an das Stützelement angeschweißt werden kann. So lassen sich die Herstellungskosten auf ein Minimum beschränken, da der Stanzvorgang mit geringem wirtschaftlichen Aufwand durchführbar ist.The extension piece is preferably designed as a stamped part, which can be welded, for example, to the support element. Thus, the production costs can be kept to a minimum, since the punching process is feasible with little economic effort.

Das Ansatzstück kann beispielsweise im wesentlichen flächig ausgeführt werden, wobei es natürlich eine gewisse Stärke besitzen muß, um den auftretenden Kräften standhalten zu können.The extension can for example be carried out substantially flat, and it must of course have a certain strength in order to withstand the forces that can occur.

Bei einer möglichen Ausführungsform des Ansatzstücks weist dieses auf seiner Ober- und Unterseite zueinander versetzt jeweils zumindest zwei Vorsprünge auf. In diesem Fall kann die Lasche des Geländerelements bei senkrecht zum Stützelement ausgerichtetem Geländerelement auf das Ansatzstück unter Ausführung von Schwenkbewegungen aufgefädelt werden, wobei bei jeder Schwenkbewegung die Lasche über einen Vorsprung des Ansatzstücks bewegt wird. Durch aufeinanderfolgende gegenläufige Schwenkbewegungen wird die Lasche dabei abwechselnd über die auf der Ober- und Unterseite des Ansatzstücks vorgesehenen Vorsprünge bewegt.In one possible embodiment of the extension piece, this has on its top and bottom side offset from each other at least two projections. In this case, the tab of the railing element can be threaded at perpendicular to the support element aligned railing element on the extension piece under execution of pivotal movements, with each pivotal movement, the tab is moved over a projection of the extension piece. By successive opposing pivoting movements, the tab is alternately moved over the projections provided on the top and bottom of the extension piece.

Bevorzugt ist es, wenn die Lasche als sich in Längsrichtung des Geländerelements erstreckendes Langloch ausgeführt ist, da in diesem Fall die Lasche auf das Ansatzstück unter Ausführung einer im wesentlichen linearen Bewegung aufsteckbar ist, wenn Stützelement und Geländerelement einen Winkel einschließen, der beispielsweise kleiner als 45° ist. Einen solchen Winkel schließen Stützelement und Geländerelement in demjenigen Stadium der Montage bzw. Demontage ein, in dem das Geländerelement ein freies, das heißt ein nicht mit einem Stützelement gekoppeltes Ende besitzt und das andere Ende mit einem Stützelement verbunden bzw. von einem solchen gelöst werden soll. In diesem Fall befindet sich die Kopplungsstelle zwischen Stützelement und Geländerelement beispielsweise ungefähr 3 m oberhalb der Bodenplatte, auf der der Monteur gerade steht, so daß es von Vorteil ist, wenn die entsprechende Kopplung durch eine einfache Linearbewegung herstellbar bzw. aufhebbar ist.It is preferred if the tab is designed as extending in the longitudinal direction of the railing element elongated hole, since in this case the tab is attachable to the extension piece under execution of a substantially linear movement, if the support element and railing element form an angle, for example, less than 45 ° is. At such an angle support element and railing element in the stage of assembly or disassembly include, in which the railing element has a free, that is not coupled to a support member end and the other end is to be connected to a support member or detached from such , In this case, the coupling point between the support element and railing element, for example, about 3 m above the bottom plate on which the fitter stands straight, so that it is advantageous if the corresponding coupling can be produced or canceled by a simple linear movement.

Bei einer bevorzugten Ausführungsform der Erfindung befinden sich bei aufgestelltem Gerüst zwei jeweils für ein separates Geländerelement vorgesehene Befestigungspositionen eines Stützelements oberhalb der für die Bodenplatte vorgesehenen Befestigungsposition dieses Stützelements. So können zwei Geländerelemente in unterschiedlichem Abstand zu der nachträglich zu montierenden Bodenplatte vorgesehen werden, wodurch der zu bewirkende Seitenschutz erhöht wird.In a preferred embodiment of the invention are in erected scaffold two each provided for a separate railing element mounting positions of a support element above the provided for the bottom plate mounting position of this support element. Thus, two railing elements can be provided at different distances from the subsequently to be mounted bottom plate, whereby the side protection to be achieved is increased.

Der Abstand zwischen der für das zweite Geländerelement vorgesehenen Befestigungsposition und der für die Bodenplatte vorgesehenen Befestigungsposition beträgt beispielsweise zwischen 30 cm und 70 cm, insbesondere ungefähr 50 cm. Es ist folglich möglich, beispielsweise zwei Geländerelemente im Abstand von 50 cm und 100 cm zur Bodenplatte vorzusehen.The distance between the fastening position provided for the second railing element and the fastening position provided for the floor plate is, for example, between 30 cm and 70 cm, in particular approximately 50 cm. It is therefore possible, for example, to provide two railing elements at a distance of 50 cm and 100 cm to the bottom plate.

Die Anzahl der bei der Montage bzw. Demontage zu bewegenden Teile kann in letztgenanntem Fall dadurch reduziert werden, daß die beiden zu einem Stützelement gehörenden Geländerelemente gelenkig miteinander verbunden sind. Diese Gelenkverbindung ermöglicht, daß beide Geländerelemente gemeinsam auf die vorstehend bereits beschriebene Weise nach oben in ihre Horizontalposition verschwenkbar sind. Anstelle von zwei einzelnen Geländerelementen muß jedoch nur ein beide Geländerelemente umfassendes Teil bewegt werden, und durch die genannte gelenkige Verbindung der beiden Geländerelemente wird eine zusätzliche Stabilisierung des Gesamtgerüsts erreicht.The number of moving during assembly or disassembly parts can be reduced in the latter case, characterized in that the two belonging to a support element railing elements are hinged together. This articulated connection makes it possible for both railing elements to be jointly pivoted upward in the horizontal position in the manner already described above. Instead of two individual railing elements, however, only a part comprising both railing elements must be moved, and by means of said articulated connection of the two railing elements an additional stabilization of the overall framework is achieved.

Die bei aufgestelltem Gerüst wirksame Gesamtlänge eines Stützelements kann zwischen 180 cm und 220 cm, insbesondere ungefähr 200 cm betragen.The effective when erected framework total length of a support member may be between 180 cm and 220 cm, in particular about 200 cm.

Die bei aufgestelltem Gerüst wirksame Gesamtlänge eines in der untersten Gerüstebene einsetzbaren Stützelements kann zwischen 280 cm und 330 cm, insbesondere ungefähr 300 cm betragen, wobei ein derartiges Stützelement zwei Befestigungspositionen für zwei in unterschiedlichen Gerüstebenen anzuordnende Bodenplatten aufweisen kann. Bei derart bemessenen Stützelementen in der untersten Gerüstebene wird vermieden, daß bereits in der untersten Gerüstebene eine Stoß- bzw. Koppelstelle zwischen zwei übereinander angeordneten Stützelementen vorgesehen werden muß, die aufgrund der hohen, in der untersten Ebene wirksamen Kräfte einen Schwachpunkt des Gesamtgerüsts bilden würde.The effective in erected scaffold overall length of usable in the lowermost framework level support member may be between 280 cm and 330 cm, in particular about 300 cm, wherein such support member may have two attachment positions for two to be arranged in different scaffolding levels floor panels. With such dimensioned support elements in the lowest level of the scaffold, it is avoided that a shock or coupling point between two superimposed support elements must already be provided in the lowest scaffold level, which would form a weak point of the overall framework due to the high, effective in the lowest level forces.

Die Anzahl der bei der Montage bzw. Demontage zu bewegenden Teile kann dadurch zusätzlich verringert werden, daß zwei parallel ausgerichtete Stützelemente, die insbesondere bei aufgestelltem Gerüst an einer Schmalseite einer Bodenplatte zu liegen kommen, über eine Querstrebe fest miteinander verbunden sind. In diesem Fall ergibt sich zumindest annähernd eine H-Form der beiden miteinander verbundenen Stützelemente.The number of moving during assembly or disassembly parts can be further reduced by two parallel aligned support elements, which come to rest in particular when erected scaffolding on a narrow side of a bottom plate, are firmly connected to each other via a cross-strut. In this case, at least approximately results in an H-shape of the two interconnected support elements.

Da vor Fassaden errichtete Gerüste oftmals nur auf einer Seite Geländerelemente benötigen, ist es bei auf die beschriebene Weise miteinander verbundenen Stützelementen ausreichend, wenn lediglich eines dieser beiden Stützelemente zumindest eine Befestigungsposition für ein Geländerelement aufweist.As erected in front of scaffolding frameworks often require only on one side, it is sufficient in interconnected in the manner described support elements, if only one of these two support elements has at least one mounting position for a railing element.

Im Rahmen der miteinander verbundenen Stützelemente ist es möglich, zwei Stützelemente miteinander zu verbinden, die unterschiedliche Längen aufweisen, bzw. die im wesentlichen gleiche Längen aufweisen, jedoch in vertikaler Richtung versetzt zueinander angeordnet sind.In the context of the interconnected support elements, it is possible to connect two support elements which have different lengths, or which have substantially equal lengths, but are arranged offset from one another in the vertical direction.

Weitere bevorzugte Ausführungsformen der Erfindung sind in den Unteransprüchen angegeben.Further preferred embodiments of the invention are specified in the subclaims.

Nach Fig. 1 befindet sich ein Fassadengerüst an einem Bauwerk 1 im Aufbau. Auf dem Erdboden 2 sind vier Stützelemente 3 zur Ausbildung von Vertikalstützen in einer Anordnung mit rechteckiger Grundfläche abgestützt, wobei die längere Seite der rechteckigen Grundfläche parallel zur Vorderfront des Bauwerks 1 verläuft.According to Fig. 1 is a facade scaffolding on a building 1 under construction. On the ground 2 four support elements 3 are supported for the formation of vertical supports in an arrangement with a rectangular base, wherein the longer side of the rectangular base extends parallel to the front of the building 1.

Die der untersten Gerüstebene zugeordneten Stützelemente 3 sind bodenseitig über höhenverstellbare Spindelanordnungen 4 abgestützt und durch Querträger 5 und Diagonalstreben 6 zu einem tragfähigen Grundgestell 7 vervollständigt. Dieses Grundgestell 7 setzt sich in Fig. 1 unten rechts in entsprechender, aus Gründen der Übersichtlichkeit nicht dargestellter Weise fort.The support elements 3 assigned to the lowermost frame level are supported on the bottom side by height-adjustable spindle arrangements 4 and are completed by cross beams 5 and diagonal struts 6 to form a load-bearing base frame 7. This base frame 7 is continued in Fig. 1 bottom right in corresponding, not shown for reasons of clarity manner.

Auf zwei hintere, in geringerem Abstand hintereinander angeordnete Vertikalstützenvorsprünge 8 des Grundgestells 7 sind weitere, teilweise miteinander verstrebte Stützelemente zur Ausbildung von Vertikalstützen aufgesteckt. In der unmittelbar an das Grundgestell 7 anschließenden Etage A sind als Stützelemente ein Zwischenstück 9, ein Verbindungsstück 10 sowie ein Stirnrahmen 11 vorgesehen, wobei der Stirnrahmen 11 aus zwei parallel zueinander verlaufenden Stützelementen besteht, die über eine Querstrebe fest miteinander verbunden sind.On two rear, at a shorter distance one behind the other arranged vertical support projections 8 of the base frame 7 more, partially braced together supporting elements for the formation of vertical supports are attached. In the directly adjoining the base frame 7 A floor are as support elements, an intermediate piece 9, a connecting piece 10 and an end frame 11 is provided, wherein the end frame 11 consists of two mutually parallel support elements which are firmly connected to each other via a crossbar.

Für die sich an die Etage A anschließenden weiteren Etagen B bis F werden auf die Stützelemente bzw. auf das Verbindungsstück 10 und den Stirnrahmen 11 der Etage A weitere Verbindungsstücke 10 und Stirnrahmen 11 aufgesteckt. Die Form eines Stirnrahmens 11 ist besonders gut bei dem für die Etage E vorgesehenen Stirnrahmen 11 zu erkennen, welcher bei dem in Fig. 1 dargestellten Aufbauschritt gerade von einem Monteur 12 gehalten wird.For the subsequent to the floor A further floors B to F are on the support elements or on the connecting piece 10 and the end frame 11 of the floor A more connecting pieces 10 and end frame 11 attached. The shape of an end frame 11 can be seen particularly well in the end frame 11 provided for the floor E, which is held in the assembly step shown in FIG. 1 by a fitter 12.

Die Stoßstellen zwischen Grundgestell 7, Zwischenstücken 9, Verbindungsstücken 10 und Stirnrahmen 11, an denen jeweils Steckverbindungen vorgesehen sind, sind für den stirnseitigen Bereich des Gesamtgerüsts in Fig. 1 durch kurze horizontale Striche gekennzeichnet.The joints between the base frame 7, spacers 9, connectors 10 and end frame 11, at which each plug connections are provided, are characterized for the frontal region of the overall frame in Fig. 1 by short horizontal lines.

Das Aufbauschema der Vertikalstützen gemäß Fig. 1 wird nachstehend unter Erläuterung der Fig. 4b nochmals beschrieben.The construction scheme of the vertical supports of FIG. 1 will be described below with explanation of Fig. 4b again.

Entlang des Bauwerks 1 sind in gleichmäßigen Abständen insgesamt sieben Vortikalstützenanordnungen aus vertikal übereinander zusammengesetzten Zwischenstücken 9, Verbindungsstücken 10 und Stirnrahmen 11 vorgesehen.Along the structure 1, a total of seven Vortikalstützenanordnungen from vertically stacked spacers 9, connectors 10 and end frame 11 are provided at regular intervals.

Zwischen zwei entlang des Bauwerks 1 hintereinander angeordneten Vertikalstützenanordnungen sind jeweils rechteckige Bodenplatten 14 gehalten, die letztlich die verschiedenen Arbeitsebenen für die einzelnen Etagen A bis F bilden.Between two along the structure 1 successively arranged vertical support assemblies each rectangular bottom plates 14 are held, which ultimately form the various working levels for the individual floors A to F.

Das Fassadengerüst weist weiterhin zwei nach vom vorragende Hilfsgerüste 15 bzw. 16 auf.The facade scaffolding also has two to from the protruding scaffolds 15 and 16 respectively.

Zur Sicherung der auf den Bodenplatten 14 arbeitenden Personen 12, 17 sind an den Vorderseiten der Stirnrahmen 11 in geeigneter Höhe Geländerelemente 18 vorgesehen, wobei die Montage dieser Geländerelemente auf erfindungsgemäße Weise derart erfolgt, daß jeweils zuerst die Geländerelemente 18 einer Etage und anschließend erst die zu dieser Etage gehörende Bodenplatte 14 montiert wird.To secure the persons working on the bottom plates 14 persons 12, 17 are provided on the front sides of the end frame 11 at a suitable height railing elements 18, wherein the mounting of these railing elements according to the invention is carried out such that each first the railing elements 18 a floor and then only to this floor belonging bottom plate 14 is mounted.

Bei der in Fig. 1 dargestellten Ausführungsform der Erfindung werden vom Monteur 12 die Geländerelemente 18 zuerst an den Befestigungspositionen 19 des Stirnrahmens 11' befestigt. Anschließend wird der Stirnrahmen 11" mit dem den Befestigungspositionen 19 abgewandten Ende der Geländerelemente 18 an den Befestigungspositionen 20 verbunden, so daß die beiden Stirnrahmen 11', 11" gemeinsam mit den beiden Geländerelementen 18 ein Parallelogramm bilden. Von Bedeutung ist, daß die Geländerelemente 18 an den Stirnrahmen 11', 11" gelenkig angebracht sind, so daß es für den Monteur 12 möglich ist, die Gesamtanordnung am Stirnrahmen 11" zu greifen und in Pfeilrichtung nach oben zu verschwenken, um anschließend ein Aufstecken des Stirnrahmens 11" auf den daruntediegenden Stirnrahmen 11 bzw. das darunterliegende Verbindungsstück 10 zu ermöglichen.In the embodiment of the invention shown in Fig. 1, the handrail elements 18 are first attached to the mounting positions 19 of the end frame 11 'by the fitter 12. Subsequently, the end frame 11 "is connected to the fastening positions 19 remote from the end of the railing elements 18 at the attachment positions 20, so that the two end frames 11 ', 11 "form a parallelogram together with the two railing elements 18. What is significant is that the railing elements 18 are hinged to the end frames 11', 11" so that it is possible for the installer 12 to control the overall arrangement to grab on the end frame 11 "and to pivot in the direction of the arrow upwards, in order subsequently to allow attachment of the end frame 11" on the daruntediegenden end frame 11 and the underlying connector 10.

Durch den vorstehend beschriebenen Arbeitsschritt wird für die Etage E bereits das Geländer 18 montiert, bevor die für die Etage E vorgesehene Bodenplatte eingebracht wird. Folglich ist sichergestellt, daß zu dem Zeitpunkt, zu dem die Bodenplatte 14 für die Etage E befestigt wird, bereits ein Seitenschutz in Form der Geländerelemente 18 existiert, so daß die Absturzgefahr für einen auf der Etage E arbeitenden Monteur von vorneherein in erheblichem Maße verringert ist.By the operation described above, the railing 18 is already mounted for the floor E before the provided for the floor E bottom plate is introduced. Consequently, it is ensured that at the time when the bottom plate 14 is fixed for the floor E, a side protection in the form of railing elements 18 already exists, so that the danger of falling for a working on the floor E fitter is reduced from the outset to a considerable extent ,

Zusätzlich zu den Geländerelementen 18 sind jeweils am stimseitigen Ende des Gesamtgerüsts Stirngeländer 21 vorgesehen.In addition to the railing elements 18 Stirngeländer 21 are each provided at the front end of the overall framework.

Insbesondere auf der vom Bauwerk 1 abgewandten Seite der Bodenplatten 14 und falls erforderlich auch an der dem Bauwerk 1 zugewandten Seite und den Stirnseiten sind unten Bordstreifen 22 lösbar befestigt, welche verhindern sollen, daß auf den Bodenplatten 14 liegende Werkzeuge beim Begehen seitlich über die Bodenplatten 14 hinausgeschoben werden und vom Fassadengerüst nach unten fallen können.In particular, on the side facing away from the structure 1 side of the bottom plates 14 and if necessary also on the building 1 side facing and the front sides strip board 22 are releasably attached below, which should prevent lying on the bottom plates 14 tools when walking sideways on the bottom plates 14th can be pushed out and fall down from the facade scaffold.

Das Gerüst weist vier bereits fertiggestellte und zwei im Bau befindliche Etagen A, B, C, D bzw. E, F auf.The scaffolding has four floors already completed and two floors A, B, C, D and E, F under construction.

Fig. 2 zeigt einzelne Arbeitsschritte beim Aufstellen eines erfindungsgemäßen Fassadengerüsts.Fig. 2 shows individual steps in setting up a facade scaffolding according to the invention.

Im Arbeitsschritt gemäß Fig. 2a steht der Monteur 12 auf einer Bodenplatte 14, die der Etage A zugeordnet ist. Der Monteur 12 ist dabei durch zumindest ein Geländerelement 18 gesichert, welches an den Befestigungspositionen 19 mit sich vertikal erstreckenden Stützelementen 3 gekoppelt ist.In the step shown in FIG. 2a, the fitter 12 is on a bottom plate 14, which is assigned to the floor A. The fitter 12 is secured by at least one railing element 18, which is coupled to the mounting positions 19 with vertically extending support members 3.

Beim Arbeitsschritt gemäß Fig. 2b steckt der Monteur 12 ein weiteres Stützelement 3' auf das Stützelement 3 auf, wobei die Stoßstelle 23 zwischen den Stützelementen 3, 3' durch eine Steckverbindung realisiert ist.In the step according to FIG. 2b, the fitter 12 puts on another support element 3 'on the support element 3, wherein the joint 23 between the support elements 3, 3' is realized by a plug connection.

Anschließend wird gemäß Fig. 2c ein weiteres Geländerelement 18' mit einem Ende an einer dafür vorgesehenen Befestigungsposition des Stützelements 3' eingehängt. Nachdem dieses Geländerelement 18' an seinem anderen Ende mit einem weiteren Stützelement 3" gekoppelt wurde, wird das Geländerelement 18' gemeinsam mit dem Stützelement 3" gemäß Fig. 2d in Pfeilrichtung nach oben verschwenkt, woraufhin gemäß Fig. 2e das Stützelement 3" auf das darunterliegende Stützelement 3 bei 23' aufgesteckt wird.Subsequently, according to FIG. 2 c, another railing element 18 'is hooked with one end to a fastening position of the support element 3' provided for this purpose. After this railing element 18 'has been coupled at its other end to a further support element 3 ", the railing element 18' together with the support element 3" according to FIG. 2d is pivoted upward in the direction of the arrow, whereupon, according to FIG. 2e, the support element 3 "on the underlying support element 3 at 23 'is plugged.

In dieser, in Fig. 2e dargestellten Position ist folglich das Geländerelement 18' für die über der Etage A liegende Etage B bereits errichtet, bevor die für die Etage B benötigte Bodenplatte 14' befestigt wurde.In this position, shown in FIG. 2e, the railing element 18 'for the floor B lying above the floor A is consequently already erected before the floor plate 14' required for the floor B has been fastened.

Gemäß Fig. 2f wird schließlich an dafürvorgesehenen Befestigungspositionen 24 der Stützelemente 3', 3" die Bodenplatte 14' für die Etage B angebracht. Anschließend kann die Etage B vom Monteur 12 erstmals betreten werden, wobei zu diesem Zeitpunkt jedoch bereits das Geländer 18' montiert ist, so daß ein Seitenschutz für den Monteur 12 besteht.Finally, according to Fig. 2f, the support elements 3 ', 3 "are attached to the floor B for the floor B, whereupon the floor B can be entered for the first time by the installer 12, at which time, however, the railing 18' is already mounted is, so that a side protection for the fitter 12 is.

Es ist zu bemerken, daß die Bodenplatten 14, 14' gemäß der Erfindung grundsätzlich entweder direkt an den Stützelementen 3, 3', 3" oder aber auch indirekt beispielsweise über mit den Stützelementen 3, 3', 3" verbundene Querstreben befestigt werden können.It should be noted that the bottom plates 14, 14 'according to the invention in principle either directly on the support elements 3, 3', 3 "or even indirectly, for example, with the support members 3, 3 ', 3" connected cross braces can be attached.

Fig. 3 zeigt verschiedene Vertikalstützenelemente, welche im Rahmen der Ansprüche zum Aufbau eines Gerüsts verwendet werden können.Fig. 3 shows various vertical support elements which can be used within the scope of the claims for the construction of a scaffold.

Fig. 3a zeigt zwei ungefähr 3 m lange Stützelemente, die für den Einsatz in der untersten Gerüstebene gedacht sind.Fig. 3a shows two approximately 3 m long support elements, which are intended for use in the lowest level of the scaffold.

Am unteren Ende sowie in einer Höhe von ungefähr 2 m weisen die Stützelemente 25 jeweils Befestigungspositionen 24 für Bodenplatten 14, 14' auf. An den Stützelementen 25 sind folglich zwei Bodenplatten 14, 14' für zwei unterschiedliche Gerüstebenen befestigbar.At the lower end and at a height of about 2 m, the support elements 25 each have fastening positions 24 for bottom plates 14, 14 '. Consequently, two base plates 14, 14 'can be fastened to the support elements 25 for two different scaffolding levels.

Ungefähr 50 cm oberhalb und auch ungefähr 100 cm oberhalb der beiden Befestigungspositionen 24 für die Bodenplatten 14, 14' sind Befestigungspositionen 19 für in Fig. 3 nicht dargestellte Geländerelemente vorgesehen.About 50 cm above and also about 100 cm above the two mounting positions 24 for the bottom plates 14, 14 'mounting positions 19 are provided for in Fig. 3, not shown handrails.

Zumindest eine der beiden Stützen 25 weist somit Befestigungspositionen 19 für Geländerelemente zweier übereinanderliegender Gerüstebenen auf.At least one of the two supports 25 thus has attachment positions 19 for railing elements of two superimposed scaffolding levels.

Die Ausführungsform gemäß Fig. 3a von Stützelementen 25 für die unterste Gerüstebene ist von Vorteil, da auf diese Weise in der untersten Ebene keine Stoßstellen bzw. Steckverbindungen vorhanden sind, die die Stabilität des Gesamtgerüsts beeinträchtigen könnten.The embodiment according to FIG. 3a of support elements 25 for the lowermost framework level is advantageous, since in this way no joints or plug connections are present in the lowest level which could impair the stability of the overall framework.

In Fig. 3b ist ein Stützelement 3 dargestellt, welches für alle auf die Stützelemente 25 folgende Gerüstebenen verwendet werden kann. Dieses Stützelement 3 ist mit seiner Unterseite auf das obere Ende der Stützelemente 25 gemäß Fig. 3a aufsteckbar.In Fig. 3b, a support member 3 is shown, which can be used for all subsequent to the support members 25 scaffolding levels. This support element 3 can be plugged with its underside onto the upper end of the support elements 25 according to FIG. 3 a.

Gemäß der Erfindung befinden sich zwei für Geländerelemente vorgesehene Befestigungsposftionen 19 des Stützelements 3 oberhalb einer für eine Bodenplatte vorgesehenen Befestigungsposition 24.According to the invention, there are two attachment positions 19 of the support element 3 provided for railing elements above a fastening position 24 provided for a base plate.

Die wirksame Gesamtlänge des Stützelements gemäß Fig. 3b beträgt ungefähr 2 m.The effective overall length of the support element according to FIG. 3b is approximately 2 m.

Im unteren Bereich der Fig. 3b ist in Draufsicht die als Rosette ausgebildete Befestigungsposition 24 dargestellt, welche Durchbrechungen zum Einhängen der Bodenplatten aufweist.In the lower part of Fig. 3b, the mounting position formed as a rosette fastening position 24 is shown in plan view, which has openings for mounting the floor panels.

Fig. 3c zeigt eine spezielle Ausführungsform eines im Rahmen der Ansprüche verwendbaren Stützelements 26, welches lediglich an seinem oberen Ende eine Befestigungsposition 24 für eine Bodenplatte aufweist. Ein derartiges Stützelement 26 kann beispielsweise in der obersten Gerüstebene zum Einsatz gebracht werden, in der sich in bestimmten Anwendungsfällen die dem Gebäude zugewandten Vertikalstützen unterhalb eines Dachvorsprungs befinden, so daß hier mittels des kurzen Stützelements 26 gemäß Fig. 3c dafür gesorgt werden kann, daß der Dachvorsprung und das Stützelement nicht miteinander kollidieren.Fig. 3c shows a specific embodiment of a support element 26 which can be used within the scope of the claims, which only at its upper end has a mounting position 24 for a bottom plate. Such a support member 26 may be used, for example, in the uppermost scaffolding level in which the building facing vertical supports are located below a roof projection in certain applications, so that it can be ensured here by means of the short support member 26 of FIG. 3c that the Roof projection and the support element do not collide with each other.

Bei der Ausführungsform gemäß Fig. 3 werden die Vertikalstützen ausschließlich aus Einzelstützen aufgebaut, wobei eventuelle Verbindungen zwischen nebeneinanderliegenden Stützelementen ausschließlich über lösbare Verbindungen hergestellt werden.In the embodiment of FIG. 3, the vertical supports are constructed exclusively of individual supports, with any connections between adjacent support elements are made exclusively via detachable connections.

Im Gegensatz hierzu ist in Fig. 4a veranschaulicht, wie zwei Stützelemente 3 über eine Querverstrebung 27 fest miteinander zu einem Stirnrahmen verbunden sind. Die Gesamtanordnung aus Stützelementen 3 und Querverstrebung 27 bildet dabei eine H-förmige Struktur.In contrast, in Fig. 4a illustrates how two support elements 3 are connected via a cross brace 27 fixed to each other to a front frame. The overall arrangement of support elements 3 and cross brace 27 forms an H-shaped structure.

Kurz oberhalb der Querverstrebung 27 sind Befestigungspositionen 24 für eine gestrichelt dargestellte Bodenplatte 14 vorgesehen. Alternativ könnte in diesem Fall die Befestigungsposition 24 auch eingespart werden, wenn die Querverstrebung als Auflager und somit als Befestigungsstelle für die Bodenplatte 14 eingesetzt wird.Just above the cross brace 27 fastening positions 24 are provided for a bottom plate 14 shown in dashed lines. Alternatively, the fastening position 24 could also be saved in this case, if the cross brace is used as a support and thus as an attachment point for the bottom plate 14.

Ungefähr 1 m oberhalb der Befestigungspositionen 24 sind weitere Befestigungspositionen 19 für in Fig. 4a nicht dargestellte Geländerelemente vorgesehen.About 1 m above the mounting positions 24 further attachment positions 19 are provided for in Fig. 4a, not shown handrail elements.

Einzelne Stirnrahmen gemäß Fig. 4a können über Steckverbindungen 23 aufeinandergesteckt werden.Individual end frame according to FIG. 4 a can be plugged together via plug connections 23.

Durch diese Ausführungsform wird die Anzahl der beim Montieren und Demontieren zu bewegenden Teile reduziert, da jeweils zwei Stützelemente 3 über die Querverstrebung 27 zu einem einzelnen Element zusammengefaßt sind.By this embodiment, the number of parts to be moved during mounting and dismounting is reduced, since in each case two support elements 3 are combined via the cross-brace 27 into a single element.

Eine alternative Ausführungsform ist in Fig. 4b gezeigt, wobei diese Ausführungsform dem Ausführungsbeispiel gemäß Fig. 1 entspricht.An alternative embodiment is shown in Fig. 4b, this embodiment corresponds to the embodiment of FIG.

Hier weisen die beiden über die Querverstrebung 27 miteinander verbundenen Stützelemente 3 unterschiedliche Längen auf. Da ein Stützelement 3 gegenüber der Ausführungsvariante gemäß Fig. 4a verkürzt ist, läßt sich auf diese Weise das Gesamtgewicht des Stirnrahmens 3, 27 reduzieren. Allerdings muß hierfür in Kauf genommen werden, daß die einzelnen Stirnrahmen mittels Verbindungsstücken 10, die wiederum ein separates Teil darstellen, über die Stoßstellen 23 gekoppelt werden müssen.Here, the two on the cross brace 27 interconnected support elements 3 different lengths. Since a support member 3 is shortened compared to the embodiment of FIG. 4a, can reduce the total weight of the end frame 3, 27 in this way. However, this must be taken into account that the individual end frame by means of connecting pieces 10, which in turn represent a separate part, must be coupled via the joints 23.

Es sei an dieser Stelle ausdrücklich erwähnt, daß zur zusätzlichen Reduzierung der Anzahl der zu bewegenden Teile die Geländerelemente bei allen Ausführungsformen gemäß den Fig. 3 und 4 auch fest an den dafür vorgesehenen Befestigungspositionen 19 angelenkt werden können, so daß bereits vor der Montage eine feste, jedoch gelenkige Verbindung zwischen Stützelementen 3 und Geländerelementen 18 vorhanden ist.It should be mentioned at this point that for additional reduction of the number of parts to be moved, the railing elements in all embodiments according to FIGS. 3 and 4 can be hinged firmly to the designated mounting positions 19, so that even before mounting a solid However, articulated connection between support elements 3 and railing elements 18 is present.

In Fig. 5 ist gezeigt, in welcher Weise Geländerelemente 18 mit Stützelementen 3 gekoppelt werden können.FIG. 5 shows the manner in which railing elements 18 can be coupled to support elements 3.

Bei der dargestellten Kopplungsmöglichkeit handelt es sich grundsätzlich um eine Hängeverbindung, die durch ein sich im wesentlichen senkrecht zum Stützelement 3 erstreckendes Ansatzstück 28 sowie eine am Endbereich eines Geländerelements 18 vorgesehene und mit dem Ansatzstück 28 koppelbare Lasche 29 realisiert ist. Das Ansatzstück 28 ist mit dem Stützelement 3 fest verbunden, insbesondere bei 32 verschweißt.The illustrated coupling possibility is basically a suspension connection, which is realized by an extension piece 28 extending substantially perpendicularly to the support element 3 and a lug 29 provided on the end region of a railing element 18 and which can be coupled to the attachment piece 28. The extension piece 28 is firmly connected to the support member 3, in particular welded at 32.

Das Ansatzstück 28 weist auf seiner Ober- und Unterseite zueinander versetzt jeweils zwei Vorsprünge 30 auf.The extension piece 28 has on its top and bottom offset from each other two projections 30.

Die Querabmessung q des Durchbruchs 31 der Lasche 29 ist so gewählt, daß das Geländerelement 18 unter der Ausführung von wechselnden Schwenkbewegungen auf das Ansatzstück 18 auffädelbar ist. Dabei ist das Maß q genau so gewählt, daß ein Auffädeln ungehindert möglich ist, jedoch nicht mittels einer linearen Bewegung des Geländerelements 18 bzw. der Lasche 29 bewerkstelligt werden kann, wenn Geländerelement 18 und Stützelement 3 ungefähr senkrecht zueinander ausgerichtet sind.The transverse dimension q of the opening 31 of the tab 29 is selected so that the railing element 18 can be threaded onto the attachment piece 18 under the effect of alternating pivoting movements. The dimension q is chosen so that a threading is possible without hindrance, but can not be accomplished by means of a linear movement of the railing element 18 and the tab 29 when railing element 18 and support member 3 are aligned approximately perpendicular to each other.

Dadurch, daß zur Befestigung des Geländerelements 18 an dem Stützelement 3 die genannte Schwenk- bzw. Fädelbewegung nötig ist, wird sichergestellt, daß sich das Geländerelement 18 nicht auf unbeabsichtigte Weise durch die Einwirkung von horizontal gerichteten Kräften vom Stützelement 3 lösen kann. Diese Sicherung wird zudem dadurch begünstigt, daß die Anschlagfläche des am nächsten am Stützelement 3 gelegenen Vorsprungs 30 des Ansatzstücks 28 senkrecht und somit parallel zum Stützelement 3 verläuft.The fact that the said pivoting or threading movement is necessary for fastening the railing element 18 to the support element 3, it is ensured that the railing element 18 can not solve in an unintentional manner by the action of horizontally directed forces from the support member 3. This backup is further facilitated by the fact that the abutment surface of the nearest to the support member 3 projection 30 of the extension piece 28 is perpendicular and thus parallel to the support member 3.

Die weiteren Anschlagflächen der Vorsprünge 30 können beispielsweise schräg ausgeführt sein, um so das Auffädeln der Lasche 29 zu erleichtern.The further abutment surfaces of the projections 30 may for example be made oblique, so as to facilitate the threading of the tab 29.

Der Abstand d zwischen den dem Stützelement 3 zugewandten Anschlagflächen der Vorsprünge 30 und dem Stützelement 3 ist so gewählt, daß die Laschen 29 zweier sich in entgegengesetzten Richtungen erstreckender Geländerelemente 18 auf ein einzelnes Ansatzstück 28 auffädelbar sind.The distance d between the support member 3 facing abutment surfaces of the projections 30 and the support member 3 is selected so that the tabs 29 of two extending in opposite directions railing elements 18 are auffädelbar to a single extension piece 28.

Bei Befestigung des ersten Endes eines Geländerelements 18 am Ansatzstück 28 weist das Geländerelement 18 relativ zum Ansatzstück 28 beispielsweise die in Fig. 2 dargestellte Position auf (siehe auch Fig. 2c).When mounting the first end of a railing element 18 on the extension piece 28, the railing element 18 relative to the extension piece 28, for example, the position shown in Fig. 2 (see also Fig. 2c).

Der zwischen Stützelement 3 und Geländerelement 18 eingeschlossene Winkel α ist in diesem Fall kleiner als 45°.The included between the support element 3 and railing element 18 angle α is smaller than 45 ° in this case.

Aufgrund der als Langloch mit eine Länge 1 ausgebildeten Durchbrechung 31 der Lasche 29 ist in dieser Position ein Aufstecken des Geländerelements 18 auf das Ansatzstück 28 durch die Ausführung einer reinen Linearbewegung möglich.Because of the elongated hole with a length 1 formed opening 31 of the tab 29 is in this position, a fitting of the railing element 18 on the extension piece 28 by the execution of a pure linear movement possible.

Anschließend wird das Geländerelement 18 dann in Richtung des Pfeiles A um das Ansatzstück 28 nach oben in eine horizontale und in Fig. 5c dargestellte Position verschwenkt.Subsequently, the railing element 18 is then pivoted in the direction of arrow A about the extension piece 28 upwards into a horizontal position and shown in Fig. 5c.

In dieser Position ist nun bezüglich des Zusammenwirkens zwischen Lasche 29 und Ansatzstück 28 nicht mehr die Längsabmessung I der Durchbrechung 31 sondern deren Querabmessung q maßgeblich.In this position, it is no longer the longitudinal dimension I of the opening 31 but its transverse dimension q is decisive with respect to the interaction between tab 29 and extension piece 28.

Aufgrund der bereits beschriebenen Dimensionierung von q ist in der Position gemäß Fig. 5c wirksam verhindert, daß das Geländerelement 18 durch eine reine Linearbewegung vom Ansatzstück 28 gelöst werden kann. Ein solches Lösen ist nur durch die gezielte Ausführung von mehreren aufeinanderfolgenden Schwenkbewegungen möglich.Due to the already described dimensioning of q is effectively prevented in the position shown in FIG. 5c that the railing element 18 can be solved by a pure linear movement of the extension piece 28. Such a release is possible only by the targeted execution of several successive pivoting movements.

Im Rahmen der Patentansprüche wird das erste Ende des Geländerelements 18 auf die in den Fig. 5b und 5c gezeigte Weise mit dem Stützelement 3 gekoppelt, während das andere Ende durch das Ausführen von Schwenkbewegungen auf das zweite Stützelement 3 aufgefädelt wird.Within the scope of the claims, the first end of the railing element 18 is coupled to the support element 3 in the manner shown in FIGS. 5b and 5c, while the other end is threaded onto the second support element 3 by pivoting movements.

Fig. 6 zeigt alternative Ausführungsformen des Ansatzstücks gemäß Fig. 5.FIG. 6 shows alternative embodiments of the attachment according to FIG. 5.

In Fig. 6a ist das Ansatzstück durch zwei übereinander angeordnete Teilstücke 33, 34 gebildet, wobei das untere Teilstück 34 zwei sich nach oben erstreckende Vorsprünge 30 und das obere Teilstück auf seiner Unterseite zwei mit den Vorsprüngen 30 ausgerichtete Ausnehmungen 35 aufweist.In Fig. 6a, the extension piece is formed by two superimposed portions 33, 34, wherein the lower portion 34 has two upwardly extending projections 30 and the upper portion on its underside two aligned with the projections 30 recesses 35.

Diese Ausführungsform funktioniert in etwa wie die Ausführungsform gemäß Fig. 5, wobei die Lasche 29 über das untere Teilstück 34 gefädelt wird.This embodiment works much like the embodiment of FIG. 5, wherein the tab 29 is threaded over the lower portion 34.

Fig. 6b zeigt eine Fig. 6a entsprechende Ausführungsform, wobei lediglich Vorsprünge 30 und Ausnehmungen 35 in umgekehrter Weise am oberen bzw. unteren Teilstück 33', 34' angeordnet sind.Fig. 6b shows a Fig. 6a corresponding embodiment, wherein only projections 30 and recesses 35 in the reverse manner at the upper and lower portion 33 ', 34' are arranged.

Die Erfindung ist nicht auf die vorstehend beschriebenen Ausführungsbeispiele beschränkt, es lassen sich im Rahmen der Patentansprüche eine Vielzahl von anderen Ausführungsvarianten realisieren.The invention is not limited to the embodiments described above, it can be realized in the context of the claims, a variety of other embodiments.
