Description

TECHNISCHES GEBIETTECHNICAL AREA

Die vorliegende Erfindung betrifft eine voreilende Geländervorrichtung für ein Systemgerüst, das Gerüstprofile, wie Querriegel, Geländerstäbe oder dergleichen aufweist. Die vorliegende Erfindung betrifft darüber hinaus ein Verfahren zur Montage einer derartigen Geländervorrichtung.The present invention relates to a leading railing apparatus for a system scaffold having scaffolding profiles such as crossbars, balusters or the like. The present invention further relates to a method for assembling such a railing device.

STAND DER TECHNIKSTATE OF THE ART

Bei den bekannten Layher-Blitz- und Layher-Allround-Gerüstsystemen werden die einzelnen Gerüstetagen aus Systembauteilen montiert. Dabei erfolgt der Montagevorgang von unten nach oben. Nachdem jeweils die Vertikalstiele beziehungsweise Vertikalrahmen, die Riegel, die Beläge, die Geländerholme und gegebenenfalls die Diagonalen pro Etage montiert sind, kann zunächst der Belag für die darüber zu montierende Etage eingehängt werden. Wenn der Monteur die neu zu erstellende Etage erreicht, muss dafür gesorgt werden, dass bereits in diesem Zustand gewisse Sicherungs elemente vorhanden sind, die für ihn einen Halt bieten. Bei den genannten Gerüstsystemen werden voreilende Geländerstützen eingesetzt. Das heißt, wenn der Monteur die "neue" Etage erreicht, sind zumindest Geländerpfosten vorhanden, an denen er einen Geländerholm befestigen kann. Dieses Geländer muss jedoch auf jeder Ebene montiert und demontiert werden.In the case of the well-known Layher Blitz and Layher Allround scaffolding systems, the individual scaffoldings are assembled from system components. The assembly process is carried out from bottom to top. After each of the vertical stems or vertical frame, the bars, the coverings, the railing spars and possibly the diagonals are mounted per floor, the covering can be hung for the above to be mounted floor first. When the installer reaches the newly created floor, it must be ensured that already in this state certain security elements are present, which provide a stop for him. The above-mentioned scaffolding systems use leading guardrails. That is, when the fitter reaches the "new" floor, at least railing posts are available to which he can attach a railing spar. However, this railing must be mounted and dismantled at each level.

Es sind Gerüstsysteme bekannt, bei denen Rahmen eingesetzt werden, die die Geländer und Diagonalen ersetzen. Nach der Montage eines derartigen Rahmens bildet der obere Horizontalriegel bereits das Geländer für die darüber noch zu montierende Gerüstetage. Die Rahmenkonstruktion selbst ist Bestandteil des Gerüstes. Es ist eine weitere Ausführungsform bekannt, bei der ebenfalls ein Rahmen eingesetzt wird, dessen oberer Horizontalriegel das vorauseilende Geländer bildet. Dieser Rahmen wird bei der Montage in zwei bereits montierte Geländerholme eingehängt und muss anschließend etagenweise versetzt werden, um ein vorauseilendes Geländer zu gewährleisten. Beide Rahmenkonstruktionen sind relativ sperrig, schwer und daher in ihrer Montage aufwändig. In jedem Fall müssen bei der Montage beziehungsweise Demontage mehrere Monteure eingesetzt werden.Scaffolding systems are known in which frames are used to replace the railings and diagonals. After mounting such a frame, the upper horizontal bar already forms the railing for the still to be mounted scaffolding days. The frame construction itself is part of the framework. Another embodiment is known in which a frame is likewise used whose upper horizontal bar forms the leading railing. This frame is hung during installation in two already mounted railing spars and must then be added floor by floor to ensure an anticipatory railing. Both frame structures are relatively bulky, heavy and therefore expensive to assemble. In any case During assembly or disassembly, several fitters must be used.

Aus der EP 1 338 723 A2 ist ein voreilendes Geländer bekannt, bei dem es möglich ist, von einer bestehenden Gerüstetage aus einen temporären Geländerholm für eine darüber zu montierende Gerüstetage vorzusehen. Diese Konstruktion ist an die bestehenden Gerüstsysteme angepasst und ermöglicht eine einfache Montage.From the EP 1 338 723 A2 a leading railing is known, in which it is possible to provide from an existing scaffolding days of a temporary railing spar for an above it to be mounted scaffolding days.

Die Geländerlängsstiele sind lösbar an den Längsstielen des Gerüsts befestigbar. Zum Lösen der Geländerlängsstiele wird eine oberseitig zugängliche Löseeinrichtung eingesetzt, die mit an den Geländerlängsstielen vorhandenen Fixiereinheiten in Verbindung steht.From the EP 1 571 275 A2 a leading railing is described in the use of scaffolding longitudinal stems displaceable railing longitudinal stems, being used between two railing longitudinal stems top telescopic scaffolding bar.

The overlapping unit 18 is designed to be open at the bottom, so that it can overlap a framework profile, for example a balustrade, of an existing framework at least in regions with a positive fit.

In etwa der Mitte der Geländervorrichtung 10 ist eine längsverschieblich an den Längsstielen 12.1, 12.2 gelagerte verschiebliche Untergreifungseinheit 16 vorhanden, die als durchgehendes einstückiges Querprofil ausgebildet ist. Die Untergreifungseinheit 16 ist nach oben offen ausgebildet, so dass sie ein Gerüstprofil, zum Beispiel einen Querriegel, eines bestehenden Gerüsts zumindest bereichsweise formschlüssig untergreifen kann.In about the middle of the railing device 10 is a longitudinally displaceable on the longitudinal stems 12.1, 12.2 mounted displaceable sub-gripping unit 16 is provided, which is formed as a continuous one-piece cross-section. The sub-gripping unit 16 is designed to be open at the top so that it can grasp a framework profile, for example a crossbar, of an existing scaffold at least partially in a form-fitting manner.

Zur Umsetzung der Längsverschieblichkeit der Untergreifungseinheit 16 sind zu beiden Seiten Längsschlittenprofile 26.1, 26.2 vorhanden, die als Rundhohlprofile ausgebildet sind, durch die hindurch die Längsstiele 12.1, 12.2 der Vorrichtung 10 geführt sind. Die Längsschlittenprofile 26.1, 26.2 weisen einen geringfügig größeren Durchmesser auf als die Längsstiele 12.7, 12.2.To implement the longitudinal displacement of the sub-gripping unit 16 longitudinal slide profiles 26.1, 26.2 are provided on both sides, which are formed as a round hollow profiles through which the longitudinal stems 12.1, 12.2 of the device 10 are guided. The longitudinal slide profiles 26.1, 26.2 have a slightly larger diameter than the longitudinal handles 12.7, 12.2.

Die Untergreifungseinheit 16 verbindet die beiden Längsschlittenprofile 26.1, 26.2.The sub-gripping unit 16 connects the two longitudinal slide profiles 26.1, 26.2.

Im oberen Endbereich verbindet die beiden Längsschlittenprofile 26.1, 26.2 ein oberes Querschlittenprofil 22. Im unteren Endbereich der Längsschlittenprofile 26.1, 26.2 verbindet ein unteres Querschlittenprofil 24 die beiden Längsschlittenprofile 26.1, 26.2.In the upper end region, the two longitudinal slide profiles 26.1, 26.2 connects an upper transverse slide profile 22. In the lower end region of the longitudinal slide profiles 26.1, 26.2, a lower transverse slide profile 24 connects the two longitudinal slide profiles 26.1, 26.2.

Das obere Querschlittenprofil 22 und das untere Querschlittenprofil 24 werden als Betätigungseinheiten für die Verschiebung der Untergreifungseinheit 16 bei der Montage verwendet und erhöhen darüber hinaus die Stabilität der Gesanntkonstruktion. Das untere Querschlittenprofil 24 ist unterhalb der Übergreifungseinheit 18 vorhanden.The upper cross-slide profile 22 and the lower cross-slide profile 24 are used as actuators for the displacement of the sub-gripping unit 16 during assembly and also increase the stability of the Gesanntkonstruktion. The lower cross slide profile 24 is present below the overlapping unit 18.

Im oberen Stirnendbereich jedes Längsschlittenprofils 26., 26.2 ist eine obere Führungseinheit 28.1, 28.2 vorhanden, die eine einwandfreie Längsverschieblichkeit des Längsschlittenprofils 26.1, 26.2 an den Längsstielen 12.1,12.2 gewährleistet. Ebenso sind im unteren Endbereich untere Führungseinheiten 30.1, 30.2 an den Längsschlittenprofilen 26..1, 26.2 vorhanden, die dem selben Zweck dienen. Die Führungseinheiten 28.1, 28.2; 30.1, 30.2 können bevorzugt als Kunststoffspritzteile ausgebildet sein.In the upper end region of each longitudinal slide profile 26, 26.2, an upper guide unit 28.1, 28.2 is provided, which ensures proper longitudinal displacement of the longitudinal slide profile 26.1, 26.2 on the longitudinal stems 12.1,12.2. Likewise, in the lower end region, lower guide units 30.1, 30.2 are provided on the longitudinal slide profiles 26..1, 26.2, which serve the same purpose. The guide units 28.1, 28.2; 30.1, 30.2 may preferably be formed as plastic injection molded parts.

In Fig. 1 schlagen die oberen Führtulgseinheiten 28.1, 28.2 der Längsschlittenprofile 26.7, 26.2 an den Längsstielen 12.1, 12.2 vorhandenen ortsfesten oberen Anschlageinheiten 32.1, 32.2 an.In Fig. 1 The upper guide pulley units 28.1, 28.2 of the longitudinal slide profiles 26.7, 26.2 strike against the longitudinal stems 12.1, 12.2 existing stationary upper stop units 32.1, 32.2.

Beabstandet zu den unteren Führungseinheiten 30.1, 30.2 sind unterseitig an den Längsstielen 12.1,12.2 untere Anschlageinheiten 34.1, 34.2 vorhanden, wobei zwischen den unteren Führungseinheiten 30.1, 30.2 und den unteren Anschlageinheiten 34.1, 34.2 elastische Mittel 20 vorhanden sind, die als Druckfedern ausgebildet sind. Die elastischen Mitteln 20.1 umgeben jeweils die Längsstielen 12.1,12.2 und liegen an den unteren Führungseinheiten 30.1, 30.2 und den unteren Anschlageinheiten 34.1, 34.2 an. Aufgrund der elastischen Wirkung der elastischen Mittel 20 werden die Längsschlittenpxofile 26.1, 26.2 nach oben gegen die obere Anschlageinheiten 32.1, 32.2 gedrückt, wobei die oberen Führungseinheiten 28.1, 28.2 in diesem Zustand an den oberen Anschlageinheiten 32.1, 32.2 anschlagen.Spaced to the lower guide units 30.1, 30.2 lower stop units 34.1, 34.2 are provided on the underside of the longitudinal stems 12.1,12.2, wherein between the lower guide units 30.1, 30.2 and the lower stop units 34.1, 34.2 elastic means 20 are provided, which are designed as compression springs. The elastic means 20.1 each surround the longitudinal stems 12.1, 12.2 and rest on the lower guide units 30.1, 30.2 and the lower stop units 34.1, 34.2. Due to the elastic action of the elastic means 20, the longitudinal slide pxofiles 26.1, 26.2 are pressed upwards against the upper stop units 32.1, 32.2, the upper guide units 28.1, 28.2 striking the upper stop units 32.1, 32.2 in this state.

Aufgrund der dargestellten Konstruktion kann die Untergreifungseinheit 16 in Richtung D (siehe Fig. 1) entgegen der Wirkung der elastischen Mittel 20.1, 20.2 nach unten gedrückt werden. Nach Entlastung sorgen dann die elastischen Mittel 20.1, 20.2 dafür, dass die Untergreifungseinheit 16 nach oben gedrückt wird.Due to the illustrated construction, the sub-gripping unit 16 in direction D (see Fig. 1 ) are pressed against the action of the elastic means 20.1, 20.2 down. After relief, the elastic means 20.1, 20.2 then ensure that the sub-gripping unit 16 is pushed upwards.

Die elastischen Mittel 20.1, 20.2 können von einem Faltbalg 36 umgeben sein, was in Fig. 1 auf der rechten Seite ausschnittsweise schematisch angedeutet ist.The elastic means 20.1, 20.2 may be surrounded by a bellows 36, which is in Fig. 1 on the right side is partially indicated schematically.

Der Abstand A zwischen der Übergreifungseinheit 18 und der Untergreifungseinheit 16 entspricht im Wesentlichen einem Systemgerüstmaß oder ist geringfügig kleiner als das jeweilige Systemgerüstmaß des Gerüsts. Im Ausführungsbeispiel beträgt das Abstandsystemmaß 102,6 cm (Zentimeter).The distance A between the overlapping unit 18 and the subgrip unit 16 essentially corresponds to a system framework dimension or is slightly smaller than the respective system framework dimension of the framework. In the exemplary embodiment, the Abstandsystemsmaß 102.6 cm (centimeters).

In Fig. 3a bis d ist der Montagevorgang beim Versetzen der voreilenden Geländervorrichtung auf eine höhere Gerüstetage schematisch dargestellt. Ausgehend von einer unteren Gerüstetage 70 mit einem zugehörigen Geländerstab 70.1 und einem zugehörigen Querriegel 70.2 ist eine momentane Gerüstetage 50 mit einem bereits montiertem Geländerstab 50.1 und einem Querriegel 50.2 dargestellt. Darüber befindet sich die noch zu montierende Gerüstetage 60 mit ihrem Querriegel 60.2. Ein Geländerstab für diese Gerüstetage 60 ist noch nicht vorhanden. Dieser soll durch die voreilende Geländervorrichtung 10 temporär zur Verfügung gestellt werden.In Fig. 3a to d the assembly process when moving the leading railing device is shown schematically to a higher equipment days. Starting from a lower scaffolding 70 with an associated balustrade 70.1 and an associated crossbar 70.2 a momentary scaffolding 50 is shown with an already mounted baluster 50.1 and a cross bar 50.2. Above this, the scaffolding 60 still to be mounted is with its transverse bar 60.2. A baluster for this equipment days 60 is not yet available. This is to be provided temporarily by the leading railing device 10.

In Fig. 3a ist die voreilende Geländervorrichtung, montiert für die momentane Gerüstetage 50, auf der die Montageperson 100 steht, dargestellt. Die Untergreifungseinheit 16 untergreift den Querriegel 50.2 der momentanen Gerüstetage 50 und die Übergreifungseinheitt 18 übergreift den Geländerstab 70.1 der unteren Gerüstetage 70. Aufgrund der elastischen Mittel 20 wird eine Druckkraft sowohl auf die Übergreifungseinheit 18 als auch auf die Untergreifungseinheit 16 ausgeübt, so dass eine sichere Verspannung der voreilenden Geländervorrichtung 10 in diesem Zustand gewährleistet ist.In Fig. 3a 1, the leading railing device mounted for the current scaffolding 50, on which the assembler 100 stands, is shown. The sub-gripping unit 16 engages under the cross bar 50.2 of the current scaffolding 50 and the Übergreifungseinheitt 18 engages the railing rod 70.1 of the lower scaffolding 70 days. Due to the elastic means 20, a compressive force is exerted both on the overlap unit 18 and on the Untergreifungseinheit 16 so that a secure clamping the leading railing device 10 is ensured in this state.

Soll nun diese Gelandervorrichtung 10 um eine Etage versetzt werden, so ergreift die Montageperson 100 die Geländervorrichtung 10 von oben und drückt mit ihrem Fuß von oben auf das obere Querschlittenprofil 22, wodurch sich die Längsschlittenprofile 26.1, 26.2 und damit auch die Untergreifungseinheit 16 und das Maß D1 nach unten verschieben. Dadurch kommt die Untergreifungseinheit 16 mit dem Querriegel 50.2 außer Eingriff. In diesem Zustand wird die Geländervorrichtung 10 nach außen geschwenkt (Pfeil V), wobei die Übexgreifungseinheit 18 in Verbindung mit dem Geländerstab 70.1 eine Schwenkachse bilden.If now this Gelandervorrichtung 10 are offset by one floor, so the assembly person 100 grasps the railing device 10 from above and pushes with her foot from above on the upper cross-slide profile 22, whereby the longitudinal slide profiles 26.1, 26.2 and thus the sub-gripping unit 16 and the measure Move D1 down. As a result, the sub-gripping unit 16 comes with the crossbar 50.2 disengaged. In this state, the railing device 10 is pivoted outwardly (arrow V), wherein the Übexgreifungseinheit 18 in conjunction with the railing rod 70.1 form a pivot axis.

Danach wird die Geländervorrichtung 10 angehoben und in geneigtem Zustand (siehe Fig. 3c) mit ihrer Übergreifungseinheit 18 in den Geländerstab 50.1 der momentanen Gerüstetage 50 von oben her eingehängt. Danach ergreift die Montageperson 100 mit der Hand das untere Querschlittenprofil 24 und zieht diese entgegen der Wirkung der elastischen Mittel 20 nach unten, wobei sich auch die Untergreifungseinheit 16 um das Maß D2 nach unten verschiebt. Dann kann die Vorrichtung 10 aus ihrer nach außen geneigten Position in ihre vertikale Endmontageposition herangeschwenkt werden (Pfeil V in Fig. 3c), wobei die Übergreifungsemheit 18 in Verbindung mit dem Geländerstab 50.1 der momentanen Gerüstetage 50 als Schwenklager dient. Hat die Vorrichtung 10 die Endposition erreicht, lässt die Montageperson 100 das untere Querschlittenprofil 24 los, wodurch dann aufgrund der Wirkung der elastischen Mittel 20 die Untergreifungseinheit 16 den Querriegel 60.2 der oberen Gerüstetage 60 formschlüssig untergreift. In diesem Zustand (siehe Fig. 3d) sind die Übergreifungseinheit 18 und die Untergreifungseinheit 16 an der bestehenden Gerüstkonstruktion zuverlässig verspannt und für die obere, noch zu montierende Gerüstetage 60 steht ein temporärer Geländerstab 14 zur Verfügung.Thereafter, the railing device 10 is raised and tilted (see Fig. 3c ) with its overlap unit 18 in the balustrade 50.1 of the current scaffolding 50 mounted from above. Thereafter, the assembler 100 grasps by hand the lower cross-slide profile 24 and pulls it against the action of the elastic means 20 down, and the sub-gripping unit 16 shifts down by the dimension D2. Then the device 10 can be pivoted from its outwardly inclined position into its vertical final assembly position (arrow V in FIG Fig. 3c ), wherein the overlap unit 18 in conjunction with the railing rod 50.1 of current equipment days 50 serves as a pivot bearing. If the device 10 has reached the end position, the assembly person 100 lets go of the lower transverse slide profile 24, as a result of which the underreaching unit 16 engages under the crossbar 60.2 of the upper equipment position 60 in a form-fitting manner due to the action of the elastic means 20. In this state (see Fig. 3d ), the overlapping unit 18 and the sub-gripping unit 16 are reliably braced to the existing scaffolding construction and for the upper, yet to be mounted scaffold assembly 60 is a temporary railing rod 14 is available.

Bei dem Versetzen der voreilenden Geländervorrichtung 10 in umgekehrte Richtung - zum Beispiel beim Abbau des Gerüsts - geht die Bedienperson 100 in umgekehrter Richtung vor, in dem zunächst die Untergreifungseinheit 16 nach unten verschoben wird, die Vorrichtung 10 nach außen geschwenkt und aus dem Geländerstab 50.1 ausgehängt wird. Dann wird die Vorrichtung 10 über die Übergreifungseinheit 18 in den Geländerstab 70.1 der unteren Gerüstetage 70 eingehängt und nach innen verschwenkt, wobei die Bedienperson 100 mit dem Fuß das obere Querschlittenprofil betätigt und nach Erreichen der Endposition loslässt, so dass die Untergreifungseinheit 16 den Querriegel 50.2 der momentanen Gerüstetage 50 untergreifen kann.When the leading railing device 10 is displaced in the opposite direction-for example when the scaffolding is being dismantled-the operator 100 proceeds in the opposite direction, in which first the sub-gripping unit 16 is displaced downwards, the device 10 is pivoted outwards and unhooked from the railing bar 50.1 becomes. Then the device 10 is suspended via the overlapping unit 18 in the railing rod 70.1 of the lower scaffolding 70 and pivoted inwards, the operator 100 with the foot actuates the upper cross slide profile and releases after reaching the end position, so that the sub-gripping unit 16 the crossbar 50.2 of current equipment days 50 can take.
