Description

Klettervorrichtung, insbesondere für ein Klettergerüst  Climbing device, in particular for a climbing frame
Die Erfindung bezieht sich auf eine Selbstklettervorrichtung insbesondere für ein Klettergerüst mit mindestens einem Linearantrieb, der zwischen mindestens einer Verschiebekonsole und mindestens einer in Verschieberichtung verlaufenden Tragschiene eine Relativbewegung erzeugt, insbesondere wenn der Linearantrieb abwechslungsweise einen Gerüstabschnitt und nach dessen Befestigung an der Wand und Lösen der Befestigung der Tragschiene diese um einen Arbeitsabschnitt verschiebt. The invention relates to a self-climbing device, in particular for a climbing frame with at least one linear drive, which generates a relative movement between at least one sliding bracket and at least one support rail running in the sliding direction, in particular if the linear drive alternately has a scaffolding section and after its attachment to the wall and loosening the attachment the mounting rail moves this by a working section.
Der Gerüstabschnitt hat beim Klettern keine direkte Verbindung zum Boden, auch wird kein Kran benötigt, wenn an dem Gerüst ein Linearantrieb, z.B. ein hydraulischer Antrieb vorgesehen ist, der im einen Arbeitsschritt den Gerüstabschnitt an der Tragschiene und im andern Arbeitsschritt die Tragschiene relativ zu dem Gerüstabschnitt anhebt. The scaffold section has no direct connection to the ground when climbing, and no crane is required if a linear drive, e.g. a hydraulic drive is provided which lifts the scaffold section on the support rail in one work step and the support rail in the other work step relative to the scaffold section.
Bei bekannten Selbstklettervorrichtungen, die z.B. in der EP 373 617 A2 beschrieben sind, ist die Tragschiene als Zahn stange ausgebildet und die Relativbewegung wird durch Eingriff von Hebeln in diese Zahnstange erzeugt. Es sind Steuervorrichtungen und Sicherheitsvorrichtungen für den Fall vorgesehen, daß aus irgend einem Grund die Relativbewegung zwischen Tragschiene und Gerüstteil gestört wird. Bekannte Steuer- und Sicherheitsvorrichtungen weisen elektronische Teile und Sensoren auf, die die Relativbewegung zwischen Tragschiene und Gerüstteil überwachen und mit Hilfe einer aufwendigen Konstruktion notfalls die Relativbewegung beenden. In the case of known self-climbing devices, which are described, for example, in EP 373 617 A2, the mounting rail is a tooth rod formed and the relative movement is generated by engagement of levers in this rack. Control devices and safety devices are provided in the event that the relative movement between the mounting rail and the scaffolding part is disturbed for some reason. Known control and safety devices have electronic parts and sensors which monitor the relative movement between the mounting rail and the scaffold part and, if necessary, terminate the relative movement with the aid of a complex construction.
Der Erfindung liegt die Aufgabe zugrunde, bei derartigen Selbstklettervorrichtungen den Antrieb einfacher und sicherer zu gestalten. The invention is based, to make the drive easier and safer in such self-climbing devices the task.
Diese Aufgabe wird gemäß der Erfindung dadurch gelöst, daß die Verbindung zwischen dem Linearantrieb und der Tragschiene durch im Abstand voneinander angeordnete Kletterköpfe hergestellt ist, die mindestens ein schwenkbares, nach Art einer Sperrklinke wirkendes Sperrglied aufweisen, daß in der bei einer Relativbewegung zwischen Tragschiene und Kletterkopf durchlaufenen Bahn des Sperrgliedes an der Tragschiene mit diesem zusammenarbeitende Sperrnocken vorgesehen sind, und daß das Sperrglied bei der Relativbewegung in einer Richtung über den Sperrnocken hinweggehoben wird, in der anderen Bewegungsrichtung aber auf die Sperrnocke aufläuft, sodaß der eine Kletterkopf diese Relativbewegung sperrend mit der Tragschiene formschlüssig verbunden ist, während am anderen Kletterkopf eine die Sperrnocken überwindende Relativbewegung stattfindet. This object is achieved according to the invention in that the connection between the linear drive and the mounting rail is made by spaced apart climbing heads, which have at least one pivotable, acting in the manner of a pawl locking member that in a relative movement between the mounting rail and climbing head traversed path of the locking member on the mounting rail with this cooperating locking cams are provided, and that the locking member is lifted during the relative movement in one direction over the locking cam, but runs in the other direction of movement on the locking cam, so that the climbing head blocks this relative movement with the mounting rail is positively connected, while on the other climbing head there is a relative movement overcoming the locking cams.
Die erfindungsgemäße Vorrichtung hat den Vorteil, daß sie ohne elektrische oder elektronische Bauteile und Schalter auskommt, die die Ursache einer Störung sein können, insbesondere aber daß ein den Anforderungen und Belastungen angepaßter Klinkenantrieb vorgesehen ist, der kaum störanfällig ist und daher größtmögliche Sicherheit gewährleistet. The device according to the invention has the advantage that it has no electrical or electronic components and switches that can be the cause of a malfunction, but in particular that a ratchet drive adapted to the requirements and loads is provided, which is hardly susceptible to malfunction and therefore ensures the greatest possible safety.
Die Erfindung eignet sich beispielsweise für eine Selbstklettervorrichtung, bei der sich die Schiene über die volle Höhe der gesamten Bewegung erstreckt, beispielsweise für Aufzüge oder dergleichen. Soll dagegen die Vorrichtung für ein Klettergerüst verwendet werden, bei dem Tragschiene und Gerüstteil abwechslungsweise angehoben werden, die Höhe der Tragschiene also etwas größer als zwei mal die Höhe eines Arbeitsabschnittes beträgt, so muß die erfindungsgemäße Vorrichtung nicht nur in einer Bewegungsrichtung, sondern auch in der umgekehrten Bewegungsrichtung voll funktionsfähig sein. Bei einer Ausführungsform der Erfindung weisen daher die Kletterköpfe in zwei gegenläufigen Bewegungsrichtungen wirksame Sperrglieder auf. The invention is suitable, for example, for a self-climbing device in which the rail extends over the full height of the entire movement, for example for lifts or the like. If, on the other hand, the device is to be used for a climbing scaffold in which the mounting rail and scaffold part are raised alternately, i.e. the height of the mounting rail is somewhat greater than twice the height of a working section, the device according to the invention must not only in one direction of movement, but also in that reverse direction of movement to be fully functional. In one embodiment of the invention, the climbing heads therefore have locking members that are effective in two opposite directions of movement.
Bei einer Ausführungsform der Erfindung weisen die Kletterköpfe ein schwenkbares Steuerglied und ein schwenkbares Sperrglied auf und es ist in der bei einer Ralativbewegung zwischen Tragschiene und Kletterkopf durchlaufenen Bahn des Steuergliedes an der Tragschiene eine Steuerkurve vorgesehen. Das Steuerglied und das Sperrglied sind so miteinander kuppelbar, daß das Sperrglied von der Steuerkurve bei der Relativbewegung in einer Richtung über den Sperrnocken hinweggehoben wird, in der anderen Bewegungsrichtung aber auf die Sperrnocke aufläuft. Dies hat den Vorteil, daß das In one embodiment of the invention, the climbing heads have a pivotable control member and a pivotable locking member, and a control curve is provided on the support rail in the path of the control member which is traversed during a ralative movement between the mounting rail and the climbing head. The control member and the locking member can be coupled to one another in such a way that the locking member is lifted away from the control cam during the relative movement in one direction over the locking cam, but runs into the locking cam in the other direction of movement. This has the advantage that the
Sperrglied formschlüssig in Eingriff gehalten wird, so daß hierzu auch keine Feder erforderlich ist, die ebenfalls die Ursache einer Störung sein kann. Diese Ausführungsform kann dahingehend weiter ausgebildet sein, daß das Steuerglied und das Sperrglied in mindestens zwei verschiedenen Winkelstellungen zueinander kuppelbar sind, wobei die eine Winkelstellung z.B. dem Anheben einer Verschiebekonsole, die andere Winkelstellung dem Anheben der Tragschiene zugeordnet ist. Locking member is held in a form-fitting manner, so that no spring is required for this, which can also be the cause of a fault. This embodiment can be further developed in such a way that the control member and the locking member can be coupled to one another in at least two different angular positions, one angular position being associated, for example, with the lifting of a sliding bracket, the other angular position with the lifting of the mounting rail.
Dadurch wird gewährleistet, daß bei jeder Relativbewegung das Sperrglied in die Bahn der Sperrnocken eingreift und dort formschlüssig gehalten ist, nämlich durch die Eingriffsbewegung, die von der Steuerkurve über das Steuerglied auf das Sperrglied übertragen ist. Dadurch kann z.B. die Verschiebekonsole nicht nur abschnittweise auf der Tragschiene nach oben verfahren werden, sondern in gleicher Weise auch abschnittsweise abgesenkt werden. This ensures that with each relative movement the locking member engages in the path of the locking cams and is held there in a form-fitting manner, namely by the engagement movement which is transmitted from the control cam via the control member to the locking member. This can e.g. the sliding bracket is not only moved upwards in sections on the mounting rail, but is also lowered in sections in the same way.
Die Kupplung zwischen Sperrglied und Steuerglied kann beliebig ausgebildet sein. The coupling between the locking member and the control member can be of any design.
Bei einer Ausführungsform der Erfindung sind das Sperrglied und das Steuerglied um eine gemeinsame Achse drehbar angeordnet. Dies ermöglicht eine besonders einfache Kupplung zwischen diesen beiden Gliedern, beispielsweise durch in beiden Gliedern befindliche Löcher, die sowohl in einer Kupplungsstellung, als auch in einer anderen Kupplungsstellung fluchten und durch die ein Bolzen hindurchgesteckt werden kann, so daß die Kupplung formschlüssig arbeitet. In one embodiment of the invention, the locking member and the control member are arranged rotatably about a common axis. This enables a particularly simple coupling between these two links, for example through holes in both links, which are aligned both in a coupling position and in another coupling position and through which a bolt can be inserted, so that the coupling works in a form-fitting manner.
Bei einer Ausführungsform der Erfindung sind Sperrglied und Steuerglied scheibenförmig ausgebildet und nebeneinander angeordnet. In one embodiment of the invention, the locking member and control member are disc-shaped and arranged next to one another.
Diese Ausführungsform der Erfindung kann dahingehend weiter ausgebildet sein, daß eines der beiden Glieder einen kreissegmentförmigen Rand aufweist und daß die Kupplung einen an dem einen der beiden Glieder befestigten in radialer Richtung beweglichen Bolzen aufweist, der mit am Rand des anderen Teiles angeordneten Rasten zusammenarbeitet. This embodiment of the invention can go further in that regard be formed that one of the two links has a circular segment-shaped edge and that the coupling has a radially movable bolt attached to one of the two links, which cooperates with detents arranged on the edge of the other part.
Das Steuerglied und die Steuerkurve können in vielfacher Weise ausgebildet sein, wesentlich ist nur, daß Steuerglied und Steuerkurve eine genaue Bewegung von der Steuerkurve formschlüssig auf das Sperrglied übertragen. The control member and the control cam can be designed in many ways, the only essential thing is that the control member and control cam transmit a precise movement from the control cam in a form-fitting manner to the locking member.
Bei einer Ausführungsform der Erfindung weist das Sperrglied zwei radial zur Schwenkachse sich erstreckende Arme auf, in einen Kupplungsstellung ragt der eine Arm und in der anderen Kupplungsstellung der andere Arm in die Bahn der Sperrnocken hinein. In one embodiment of the invention, the locking member has two arms extending radially to the pivot axis, one arm projects into a coupling position and the other arm projects into the path of the locking cams in the other coupling position.
Bei einer Ausführungsform der Erfindung weist auch das Steuerglied zwei radial zur Schwenkachse sich erstreckende Arme auf, von denen einer mit der Steuerkurve zusammenarbeitet. In one embodiment of the invention, the control member also has two arms extending radially to the pivot axis, one of which cooperates with the control cam.
Die Steuerkurve kann beliebig ausgebildet sein, beispielsweise aus einer kontinuierlichen Kurvenlinie bestehen. Bei einer Ausführungsform der Erfindung weist die Steuerkurve jedoch einzelne, über die Länge der Tragschiene verteilt angeordnete Kurvenstücke auf, die an der Stelle, die dem tiefsten Eingriff des Sperrgliedes in die Bahn der Sperrnocken entspricht, einen parallel zur Bewegungsrichtung verlaufenden Abschnitt aufweisen. The control curve can be of any design, for example consist of a continuous curve line. In one embodiment of the invention, however, the control cam has individual curve pieces which are arranged distributed over the length of the mounting rail and which have a section running parallel to the direction of movement at the point which corresponds to the deepest engagement of the locking member in the path of the locking cams.
Diese Ausführungsform kann dahingehend weiter ausgebildet sein, daß die Länge dieses parallel zur Bewegungsrichtung verlaufenden Abschnittes der Kurvenstücke etwa dem Abstand zwischen den Punkten entspricht, mit denen die Arme des Steuergliedes in einer Winkelstellung an einem Kurvenstück aufliegen, so daß in einer Winkelstellung beide Arme des Steuergliedes auf diesem geraden Abschnitt aufliegen. This embodiment can be further developed such that the length of this section of the curve pieces running parallel to the direction of movement is approximately the distance between the points with which the arms of the control element rest in an angular position on a curve piece, so that in an angular position both arms of the control element rest on this straight section.
Der erfindungsgemäße Kletterkopf kann sowohl bei Gerüsten verwendet werden, bei denen ein Abschnitt eines Gerüstes, der Arbeitsbühnen enthalten kann, durch eine in seiner Mitte angeordnete Selbstklettervorrichtung angehoben wird, als auch bei Gerüsten, bei denen der bewegliche Gerüstabschnitt durch zwei oder mehrere Klettervorrichtungen angehoben wird, die im Gleichlauf arbeiten. Auch können die Kletterköpfe bei anderen Hebevorrichtungen vorgesehen sein, beispielsweise bei Lastenaufzügen, bei denen die Tragschiene sich nicht nur über zwei übereinander verlaufende Arbeitsstellungen, sondern über die volle Höhe erstreckt, die eine Verschiebekonsole durchlaufen soll, beispielsweise bei Lastenaufzügen für vielgeschossige Materiallager. Auch können die erfindungsgemäßen Kletterköpfe bei schräg verlaufenden Aufzügen oder dergleichen vorgesehen sein, wo eine durch eine Steuerkurve erfolgende Zwangssteuerung von wahlweise im Eingriff stehende Sperrgliedern bei Hebevorrichtungen vorteilhaft ist. The climbing head according to the invention can be used both in the case of scaffolds in which a section of a scaffold, which can contain working platforms, is raised by a self-climbing device arranged in its center, and in the case of scaffolds in which the movable scaffold section is lifted by two or more climbing devices, that work in sync. The climbing heads can also be provided in other lifting devices, for example in freight elevators, in which the mounting rail not only extends over two working positions running one above the other, but over the full height that a sliding bracket is to pass through, for example in freight elevators for multi-storey material stores. The climbing heads according to the invention can also be provided in the case of inclined lifts or the like, where a positive control of optionally interlocking locking members in lifting devices, which is effected by means of a control curve, is advantageous.

Bei der in der Zeichnung dargestellten Ausführungsform sind in dem bereits betonierten Abschnitt einer Bauwerkswand 1 mehrere Verankerungsbolzen einbetoniert. In den im Abstand der Höhe eines Betonierabschnittes übereinander angeordneten Verankerungsbolzen 2 und 3 sind Gerüstschuhe 4 und 5 befestigt, in denen eine Tragschiene 6 höhenverschieb- und feststellbar geführt ist, die einen I-förmigen Querschnitt aufweist. Der Gerüstschuh 4 führt lediglich die Schiene 6, wogegen der Gerüstschuh 5 außerdem noch Befestigungsvorrichtungen aufweist, mit denen das als Ganzes mit 7 bezeichnete Klettergerüst an der Wand 1 befestigt werden kann. Das Klettergerüst 7 weist eine Arbeitsbühne 8 auf, die an ihrem wandseitigen Ende eine Verschiebekonsole 9 aufweist, in der die Tragschiene 6 geführt ist und die in die Befestigungsvorrichtungen des Gerüstschuhes 5 eingehängt und gesichert werden kann. Auf der Arbeitsbühne 8 sind ein oder mehrere stockwerkhohe Schalelemente 10 rechtwinklig zur Wand 1 verschiebbar geführt. In the embodiment shown in the drawing, several anchoring bolts are concreted into the section of a building wall 1 that has already been concreted. In the anchoring bolts 2 and 3, which are arranged one above the other at the height of a concreting section, scaffold shoes 4 and 5 are fastened, in which a mounting rail 6, which has an I-shaped cross section, is guided so as to be vertically displaceable and lockable. The scaffolding shoe 4 only guides the rail 6, whereas the scaffolding shoe 5 also has fastening devices with which the climbing frame designated as a whole as 7 can be fastened to the wall 1. The climbing frame 7 has a working platform 8, which has a sliding bracket 9 at its wall-side end, in which the mounting rail 6 is guided and which can be hooked into the fastening devices of the scaffolding shoe 5 and secured. On the work platform 8, one or more floor-to-ceiling formwork elements 10 are slidably guided at right angles to the wall 1.
Fig. 1 zeigt das Schalelement 10 in der Stellung, in der der nächste Betonierabschnitt betoniert werden kann (die übliche Bewehrung ist nicht gezeichnet). Oberhalb der Arbeitsbühne 8 ist noch eine Vorlaufbühne 11 im Klettergerüst 7 gezeichnet, unterhalb der Arbeitsbühne 8 eine Nachlaufbühne 12. Bei der dargestellten Ausführungsform erfolgt das Klettern des Klettergerüstes 7 in den nächsten Betonierabschnitt in mehreren Schritten, weil ein für das Anheben des Klettergerüstes 7 vorgesehener Linearantrieb 13 bei der dargestellten Ausführungsform durch einen hydraulischen Zylinder verwirklicht ist, dessen Hub wesentlich kleiner als die Stockwerkhöhe ist. Als Linearantrieb kann jedoch ein Spindelantrieb, können Ketten- oder Riementriebe, Zahnstangenantriebe oder sonstige Vorrichtungen vorgesehen sein, die einen sehr viel größeren Hub ermöglichen, beispielsweise einen Hub, der in einem Arbeitsschritt das Klettergerüst 7 um die volle Höhe eines Betonierabschnittes, also beispielsweise um eine Geschoßhöhe anhebt . Fig. 1 shows the formwork element 10 in the position in which the next concreting section can be concreted (the usual reinforcement is not shown). Above the work platform 8 a leading platform 11 is also drawn in the climbing frame 7, a trailing platform 12 below the working platform 8. In the embodiment shown, the climbing frame 7 climbs into the next concreting section in several steps, because a linear drive 13 provided for lifting the climbing frame 7 is shown in the illustrated embodiment Embodiment is realized by a hydraulic cylinder, the stroke of which is significantly smaller than the floor height. However, a spindle drive, chain or belt drives, rack and pinion drives or other devices can be provided as the linear drive, which enable a much larger stroke, for example a stroke which in one work step climbs the climbing frame 7 by the full height of a concreting section, for example by one Floor height rises.
Am unteren Ende des Hydraulikantriebes 13 befindet sich an seiner Kolbenstange 16 ein Kletterkopf 14, der mit der Tragschiene 6 zusammenarbeitet. Am oberen Ende des Hydraulikantriebes 13 befindet sich ein Kletterkopf 15, der ebenfalls mit der Tragschiene 6 zusammenarbeitet, an dem aber auch die Verschiebekonsole 9 befestigt ist. At the lower end of the hydraulic drive 13 there is a climbing head 14 on its piston rod 16 which cooperates with the mounting rail 6. At the upper end of the hydraulic drive 13 there is a climbing head 15, which also cooperates with the mounting rail 6, but to which the sliding bracket 9 is also attached.
Sobald in der in Fig. 1 dargestellten Stellung der an die Schalelemente 10 angrenzende Abschnitt der Betonwand betoniert ist, werden die Schalelemente 10 nach Abbinden des Betons zurückgefahren. In diesem frisch betonierten Abschnitt sind Verankerungsbolzen 17 bereits einbetoniert, die zur Befestigung von Gerüstschuhen dienen können. As soon as the section of the concrete wall adjoining the formwork elements 10 is concreted in the position shown in FIG. 1, the formwork elements 10 are retracted after the concrete has set. In this freshly concreted section, anchoring bolts 17 are already concreted in, which can be used to fasten scaffolding shoes.
In den Fig. 3 bis 5 sind die Kletterköpfe 14 und 15 näher erläutert. Der Kletterkopf weist ein Gehäuse 18 auf, das einen Schenkel 19 des I-Profiles der Tragschiene 6 umgreift. Auf der von der Wand 1 abgewandten Stirnfläche 20 des I-Pro- files sind in der Längsmittelebene der Schiene 6 im Abstand voneinander Sperrnocken 21, 29 angeordnet, deren in Bewegungsrichtung weisende Seitenflächen rechtwinklig zu der Stirnfläche 20 verlaufen. In der Bahn dieser Sperrnocken 21, 29 befindet sich ein Sperrglied 24, das um einen Bolzen 25 im Gehäuse 18 schwenkbar gelagert ist und das zwei radiale Arme 26 und 27 aufweist, von denen je einer je nach der Drehstellung des Sperrgliedes 24 auf dem Bolzen 25 bei einer Relativbewegung zwischen der Tragschiene 6 und dem Kletterkopf 14 an der Stirnfläche 22 des oberen Sperrnockens 21 oder aber, wie in Fig. 2 dargestellt bei Bewegung des oberen Kletterkopfes nach oben, an der Stirnfläche 28 des nächst unteren Sperrnockens 29 zur Anlage kommt. 3 to 5, the climbing heads 14 and 15 are explained in more detail. The climbing head has a housing 18 which encompasses one leg 19 of the I-profile of the mounting rail 6. On the end face 20 of the I-profile facing away from the wall 1, locking cams 21, 29 are arranged in the longitudinal center plane of the rail 6 at a distance from one another, the side faces of which point in the direction of movement run at right angles to the end face 20. In the path of these locking cams 21, 29 there is a locking member 24 which is pivotally mounted about a bolt 25 in the housing 18 and which has two radial arms 26 and 27, one of which depending on the rotational position of the locking member 24 on the bolt 25 when there is a relative movement between the mounting rail 6 and the climbing head 14 on the end face 22 of the upper locking cam 21 or, as shown in FIG. 2 when the upper climbing head moves upward, the end face 28 of the next lower locking cam 29 comes to rest.
In einem Abstand seitlich neben den Sperrnocken 21 und 28 befinden sich im Abstand voneinander und über die Länge der Tragschiene 6 verteilt Kurvenstücke 30, deren in Richtung der Relativbewegung gewandte Seitenflächen Anlaufkurven 31 und 32 aufweisen. Die der Tragschiene 6 abgewandte Fläche 33 verläuft parallel zur Stirnfläche 20. Die Kurvenstücke 30 und die Sperrnocken 21, 29 sind zueinander in der Höhe versetzt auf der Tragschiene angeordnet. At a distance laterally next to the locking cams 21 and 28 are spaced apart from one another and distributed over the length of the mounting rail 6, curve pieces 30, the side surfaces of which, in the direction of the relative movement, have run-up curves 31 and 32. The surface 33 facing away from the mounting rail 6 runs parallel to the end face 20. The curve pieces 30 and the locking cams 21, 29 are offset in height from one another on the mounting rail.
In der Bahn dieser Kurvenstücke 30 weist der Kletterkopf 14 ein um den Bolzen 25 schwenkbar gelagertes Steuerglied 34 auf, das ebenfalls zwei radial sich erstreckende Arme 35 und 36 aufweist. In einer Mittelstellung, die in Fig. 2 und 3 gezeigt ist, gleiten die beiden Arme 35 und 36 über die Fläche 33 hinweg. Die Fläche 33 ist so lang, daß beide Arme 35 und 36 gleichzeitig an der Fläche 33 anliegen können. In the path of these curve pieces 30, the climbing head 14 has a control member 34 which is pivotally mounted about the pin 25 and which likewise has two radially extending arms 35 and 36. In a central position, which is shown in FIGS. 2 and 3, the two arms 35 and 36 slide over the surface 33. The surface 33 is so long that both arms 35 and 36 can abut the surface 33 at the same time.
Das Sperrglied 24 und das Steuerglied 34 sind plattenförmig ausgebildet, sie sind nebeneinander auf dem Bolzen 25 unabhängig voneinander drehbar gelagert . Auf einem der Tragschiene 6 abgewandten Teil des Steuergliedes 34 ist in einer Verlängerung 37 ein Kupplungsbolzen 38 längsverschiebbar gelagert, dessen dem Sperrglied 24 zugewandtes inneres Ende 39 mit Rasten 40 zusammenarbeitet, die am Umfang des Sperrgliedes 24 ausgespart sind. Das Ende 39 des Kupplungsbolzens 38 wird mittels einer nicht gezeichneten Druckfeder gegen den Rand des Sperrgliedes 24 gedrückt. Am Bolzen 25 angreifende Gabelenden 42 und 44 gehören zu einem Befestigungsteil, mit dem die Kolbenstange 16 mit dem unteren Kletterkopf 14 bzw. die Verschiebekonsole 9 der Arbeitsbühne 8 bzw. der mit ihr verbundene Hydraulikzylinder mit dem oberen Kletterklopf 15 verbunden ist . The locking member 24 and the control member 34 are plate-shaped formed, they are rotatably mounted on the pin 25 independently of each other. On a part of the control member 34 facing away from the mounting rail 6, a coupling bolt 38 is mounted in a longitudinally displaceable manner in an extension 37, the inner end 39 of the inner member 39 facing the locking member 24 cooperating with catches 40 which are recessed on the circumference of the locking member 24. The end 39 of the coupling pin 38 is pressed against the edge of the locking member 24 by means of a compression spring, not shown. Fork ends 42 and 44 engaging the bolt 25 belong to a fastening part with which the piston rod 16 is connected to the lower climbing head 14 or the displacement bracket 9 of the working platform 8 or the hydraulic cylinder connected to it with the upper climbing knock 15.
Der obere Kletterkopf 15 (Fig. 5) unterscheidet sich von dem unteren Kletterkopf 14 lediglich dadurch, daß der Bolzen 25 im Kletterkopf 14 lediglich in den beiden äußeren seitlichen Gehäusewangen 41 gelagert ist, wogegen beim oberen Kletterkopf 15 zwischen den Gehäusewangen 41 und dem Sperrglied 24 noch zwei Gehäusezwischenwände 43 vorgesehen sind, die zusätzlich die auf die Verschiebekonsole 9 übertragene Last des Gerüstes auf das Sperrglied 24 und die Tragschiene 6 bzw. den Gerüstschuh 5 ableiten. The upper climbing head 15 (FIG. 5) differs from the lower climbing head 14 only in that the bolt 25 in the climbing head 14 is only supported in the two outer lateral housing cheeks 41, whereas in the upper climbing head 15 between the housing cheeks 41 and the locking member 24 two intermediate walls 43 are also provided, which additionally derive the load of the scaffold transmitted to the sliding bracket 9 onto the locking member 24 and the mounting rail 6 or the scaffold shoe 5.
Ein Rastbolzen 46 ist in dem Gehäuse 18 längsverschiebbar gelagert. Er weist an seinem vorderen Ende eine federbelastete Kugel auf, die in Vertiefungen am Rand des Sperrgliedes 24 rastend eingreift und hält die durch den Kupplungs- bolzen 38 starr miteinander verbundenen Steuerglied und Sperrglied mit einer geringen Kraft in einer bestimmten Drehlage, die diese Glieder z.B. beim Überfahren einer A locking pin 46 is mounted in the housing 18 so as to be longitudinally displaceable. It has at its front end a spring-loaded ball which engages in recesses on the edge of the locking member 24 and holds the control member and locking member rigidly connected by the coupling bolt 38 with a small force in a certain rotational position, which these members e.g. when driving over one
Sperrnocke 29 und eines Kurvenstückes 30 einnehmen. Soll das Klettergerüst aus der in Fig. 1 dargestellten Stellung angehoben werden, so wird zunächst die Befestigung der Transportschiene 6 in den Gerüstschuhen 4 und 5 gelöst, wogegen die mit der Arbeitsbühne 8 verbundene Verschiebekonsole 9 in dem Gerüstschuh 5 befestigt bleibt. Wird nun der Hydraulikzylinder 13 angetrieben, so wird der am unteren Ende der Kolbenstange 16 befestigte Kletterkopf 14, der in die Tragschiene 6 eingreift, zusammen mit dieser so weit nach oben geschoben, wie es der Hub des Hydraulikzylinders 13 erlaubt . Dabei gleitet die Tragschiene 6 durch den Kletterkopf 15, der diese Bewegung der Tragschiene 6 freigibt, wogegen der Arm 26 des Sperrgliedes 24 im unteren Kletterkopf 14 hinter eine Sperrnocke greift und so die Tragschiene 6 nach oben mitnimmt. Hierauf wird die Tragschiene 6 in den Gerüst- schuhen 4 und 5 wieder befestigt und die Kolbenstange 16 wieder ausgefahren, wobei der Arm 26 des Sperrgliedes 24 in seiner Bahn befindliche Sperrnocken 21 überfährt und in der unteren Endstellung der Kolbenstange 16 wieder einen Sperrnocken untergreift . Hierauf wird die Tragschiene 6 wieder von der Wand gelöst und beim nächsten Einziehen der Kolbenstange 16 in den Hydraulikzylinder 13 wieder in Hublänge angehoben. Dieses Arbeitsspiel wiederholt sich so oft, bis die Tragschiene 16 um einen Betonierabschnitt angehoben ist und dabei in weiter oben in der Wand angeordneten Befestigungsteilen befestigt ist. Bei einem 3 m hohen Betonierabschnitt und einem Hub des Hydraulikzylinders von 60 cm wiederholt sich dieses zum Anheben der Tragschiene dienende Arbeitsspiel 5 mal. Nun steht in der in Fig. 1 gewählten Darstellung die Tragschiene 6 mit ihrem unteren Ende im Bereich des Gerüstschuhes 4 und ragt mit ihrem oberen Ende so weit über den Gerüstschuh 5 nach oben hinaus, daß das Klettergerüst 7 an der an der Wand befestigten Tragschiene 6 um einen Beto- nierabschnitt nach oben verschoben werden kann. Take locking cam 29 and a curve piece 30. If the climbing frame is to be raised from the position shown in FIG. 1, the fastening of the transport rail 6 in the scaffold shoes 4 and 5 is first released, whereas the sliding bracket 9 connected to the work platform 8 remains fixed in the scaffold shoe 5. If the hydraulic cylinder 13 is now driven, the climbing head 14, which is attached to the lower end of the piston rod 16 and engages in the mounting rail 6, is pushed together with the mounting rail 6 as far as the stroke of the hydraulic cylinder 13 permits. The mounting rail 6 slides through the climbing head 15, which releases this movement of the mounting rail 6, whereas the arm 26 of the locking member 24 in the lower climbing head 14 engages behind a locking cam and thus takes the mounting rail 6 upwards. The mounting rail 6 is then reattached in the frame shoes 4 and 5 and the piston rod 16 is extended again, the arm 26 of the locking member 24 running over locking cams 21 in its path and engaging under a locking cam again in the lower end position of the piston rod 16. Thereupon, the mounting rail 6 is detached from the wall and the stroke length is raised again the next time the piston rod 16 is pulled into the hydraulic cylinder 13. This work cycle is repeated until the mounting rail 16 is raised by a concreting section and is thereby fastened in fastening parts arranged further up in the wall. With a 3 m high concreting section and a stroke of the hydraulic cylinder of 60 cm, this working cycle for lifting the mounting rail is repeated 5 times. Now, in the illustration selected in FIG. 1, the support rail 6 stands with its lower end in the area of the scaffolding shoe 4 and projects with its upper end so far above the scaffolding shoe 5 that the climbing frame 7 on the mounting rail 6 fastened to the wall for a concrete nier section can be moved up.
Hierauf werden die Kletterköpfe 14 und 15 umgestellt, sodaß sich der Kletterkopf 14 auf einem der Sperrnocken 21, 29 der nun feststehenden Tragschiene 6 abstützt. Hierauf wird die Befestigung der Verschiebekonsole 9 in dem Gerüstschuh 5 gelöst und der Hydraulikzylinder 13 ausgefahren, wobei der obere Kletterkopf 15, der entlang der Tragschiene 6 nun nach oben gleitet, die Verschiebekonsole 9 und damit auch den Hydraulikzylinder 13 mit nach oben nimmt. Ist die Kolbenstange 16 ausgefahren, so wird die Verschiebekonsole 9 und damit auch das Klettergerüst 7 an der Wand befestigt und hierauf die Kolbenstange 16 wieder in den Zylinder 13 leer eingefahren, wobei der nun nach der Umstellung der Kletterköpfe in die Tragschiene 6 und damit in die Bahn der Sperrnocken 21, 29 eingreifende Arm 27 des Sperrgliedes 24 wegen dessen glatter Unterfläche 45 über die Sperrnocken 21, 29 hinweggleiten. The climbing heads 14 and 15 are then changed over so that the climbing head 14 is supported on one of the locking cams 21, 29 of the now fixed mounting rail 6. Then the attachment of the sliding bracket 9 in the scaffold shoe 5 is released and the hydraulic cylinder 13 is extended, the upper climbing head 15, which now slides along the mounting rail 6, taking the sliding bracket 9 and thus also the hydraulic cylinder 13 upward. If the piston rod 16 is extended, the sliding bracket 9 and thus also the climbing frame 7 are attached to the wall and then the piston rod 16 is retracted empty into the cylinder 13, the now after the conversion of the climbing heads into the mounting rail 6 and thus into the Path of the locking cams 21, 29 engaging arm 27 of the locking member 24 because of its smooth lower surface 45 slide over the locking cams 21, 29.
Ist die Kolbenstange 16 vollständig eingefahren, so wird die Befestigung der Verschiebekonsole 9 wieder gelöst, wobei sich das Gerüst über die sich an Sperrnocken abstützenden Arme 27 der Sperrglieder 24 in den Kletterköpfen 14 und 15 abstützt. Hierauf wird die Kolbenstange 16 wieder ausgefahren und damit die Verschiebekonsole 9, das Gerüst und der Hydraulikzylinder 13 um eine Hublänge nach oben geschoben, wobei der in die Bahn der Sperrnocken 21, 29 eingreifende Arm 27 des Sperrgliedes 24 des oberen Kletterkopfes 15 mit der ebenen Unterfläche 45 des Sperrgliedes 24 über die If the piston rod 16 is completely retracted, the attachment of the sliding bracket 9 is released again, the frame being supported in the climbing heads 14 and 15 by the arms 27 of the locking members 24 supported on locking cams. Then the piston rod 16 is extended again and thus the sliding bracket 9, the scaffolding and the hydraulic cylinder 13 are pushed up by a stroke length, the arm 27 of the locking member 24 of the upper climbing head 15 engaging in the path of the locking cams 21, 29 with the flat lower surface 45 of the locking member 24 on the
Sperrnocken hinweggleitet . Locking cam slides away.
Dieses Arbeitsspiel wird so lange fortgesetzt, bis die Arbeitsbühne 8 um einen Betonierabschnitt hochgehoben ist, wo- nach dann nach den Bewehrungsarbeiten und anderen vorbereitenden Arbeiten die Schalelemente 10 wieder in die Schalebene vorgefahren und dort befestigt werden und dieser Abschnitt betoniert werden kann. This work cycle is continued until the work platform 8 is raised by a concreting section, where after then after the reinforcement work and other preparatory work, the formwork elements 10 are moved back into the formwork level and fastened there and this section can be concreted.
Im folgenden werden die einzelnen Arbeitsschritte näher erläutert. The individual work steps are explained in more detail below.
Bei der in Fig. 2 dargestellten Stellung von Sperrglied 24 und Steuerglied 25, die durch den Eingriff des Kupplungsbolzens 38 in die in Fig. 5 oberste Raste 40 des Sperrgliedes 24 bestimmt ist, liegt der Arm 35 des Steuergliedes 34 noch auf der oberen Fläche 33 des Kurvenstückes 30 auf und der Arm 27 des Sperrgliedes 24 liegt durch den Arm 35 zwangsgeführt an der Stirnfläche 20 des Schenkels 19 der Tragschiene 6 an. In dieser Stellung ist die Tragschiene 6 in den Gerüstschuhen 4 und 5 befestigt, die Befestigung der Verschiebekonsole 9 an dem Gerüstschuh 5 ist jedoch gelöst, so daß sich die Verschiebekonsole 9 längs der Tragschiene 6 verschieben kann. Bei dieser Darstellung nach Fig. 2 ist vorausgesetzt, daß die Tragschiene 6 bereits in einem vorhergehenden Arbeitsschritt über die in Fig. 1 dargestellte Stellung nach oben hochgefahren worden ist. Wird nun der Hydraulikzylinder 13 beaufschlagt, so wird in der in Fig. 2 und 5 dargestellten Stellung der Kletterkopf 14 noch ein kleines Stück nach unten bewegt, bis der Arm 27 des Sperrgliedes 24 an der oberen Stirnfläche 23 des Sperrnockens 29 zur Anlage kommt und dort den unteren Kletterkopf 14 abstützt. Im weiteren Verlauf wird, da die Tragschiene 6 starr mit der Wand verbunden ist, der Hydraulikzylinder 13 in Richtung des Pfeiles 44 nach oben gefahren, wobei er den oberen Kletterkopf 15 und die mit ihm verbundene Verschiebekonsole längs der Tragschiene 6 nach oben verschiebt. Die Stellung von Sperrglied 24 und Steuerglied 34 ist im Kletterkopf 15 die gleiche wie im Kletterkopf 14, da auch im Kletterkopf 15 der Kupplungsbolzen 38 in die gleiche Raste 40 des Sperrgliedes 24 eingreift. Zwar kommt bei dieser Aufwärtsbewegung die ebene Unterfläche 45 des Sperrgliedes 24 zu einer schrägen Anlage an den nächsthöheren Sperrnocken, jedoch kann der obere Kletterkopf 15 diesen Sperrnocken überfahren, weil sich, wie man dies in Fig. 2 bezüglich des Sperrnockens 21 entnehmen kann, das Sperrglied 24 im Gegenuhrzeigersinn etwas dreht, bis der Arm 27 über die obere Fläche des Sperrnockens 21 hinweggleiten kann. Bei dieser Drehbewegung stört das Steuerglied 34 nicht, weil sein Arm 35 wegen des Höhenversatzes von Sperrnocke und Kurvenstück das betreffende Kurvenstück 30 bereits verlassen hat und daher das Steuerglied 34 diese Drehbewegung mitmachen kann. Bei dieser Anhebebewegung des Gerüstes 7 stützt sich dieses auf dem unteren Kletterkopf 14 und über den an der Sperrnocke 29 anliegenden Arm 27 auf der Tragschiene 6 ab, die wie erwähnt, bei dieser Bewegung in den Gerüstschuhen 4 und 5 und damit in der Wand 1 befestigt ist. In the position of the locking member 24 and control member 25 shown in FIG. 2, which is determined by the engagement of the coupling pin 38 in the top catch 40 of the locking member 24 in FIG. 5, the arm 35 of the control member 34 is still on the upper surface 33 of the curve piece 30 and the arm 27 of the locking member 24 is positively guided by the arm 35 against the end face 20 of the leg 19 of the mounting rail 6. In this position, the mounting rail 6 is fastened in the scaffold shoes 4 and 5, but the attachment of the sliding bracket 9 to the scaffolding shoe 5 is released, so that the sliding bracket 9 can move along the mounting rail 6. 2 it is assumed that the mounting rail 6 has already been raised in a previous step above the position shown in FIG. 1. If the hydraulic cylinder 13 is now acted upon, in the position shown in FIGS. 2 and 5 the climbing head 14 is moved a little further downward until the arm 27 of the locking member 24 comes to rest against the upper end face 23 of the locking cam 29 and there supports the lower climbing head 14. In the further course, since the mounting rail 6 is rigidly connected to the wall, the hydraulic cylinder 13 is moved upward in the direction of the arrow 44, wherein it moves the upper climbing head 15 and the displacement console connected to it upwards along the mounting rail 6. The position of Locking member 24 and control member 34 is the same in climbing head 15 as in climbing head 14, since coupling pin 38 engages in the same catch 40 of locking member 24 in climbing head 15 as well. During this upward movement, the flat lower surface 45 of the locking member 24 comes to an oblique contact with the next higher locking cam, but the upper climbing head 15 can drive over this locking cam because, as can be seen in FIG. 2 with regard to the locking cam 21, the locking member 24 rotates slightly counterclockwise until the arm 27 can slide over the upper surface of the locking cam 21. During this rotary movement, the control member 34 does not interfere because its arm 35 has already left the relevant curve piece 30 because of the height offset of the locking cam and curve piece and therefore the control member 34 can take part in this rotary movement. During this lifting movement of the scaffold 7, it is supported on the lower climbing head 14 and via the arm 27 resting on the locking cam 29 on the mounting rail 6, which, as mentioned, is fastened in this way in the scaffolding shoes 4 and 5 and thus in the wall 1 is.
Ist diese Bewegung abgeschlossen, so wird die Verschiebekonsole 9 an dem nächsthöheren Gerüstschuh eingehängt und befestigt. Die Kolbenstange 16 wird nun in den beim vorhergehenden Arbeitsschritt mit dem Kletterkopf angehobenen Hydraulikzylinder 13 eingefahren. Bei diesem Leerhub überfährt der untere Kleterkopf 14 in der gleichen Weise wie zuvor der obere Kletterkopf 15 die Sperrnocken. Dann wird die Verschiebekonsole wieder von der Wand 1 gelöst, sodaß beim Wiederausfahren der Kolbenstange die Verschiebekonsole, abgestützt auf den unteren Kletterkopf 14, wieder um die Hublänge angehoben wird. Hat das Gerüst nach mehreren Arbeits- schritten seine obere Endlage erreicht und ist es an der Wand befestigt, so werden die Sperrglieder 24 gegenüber der Steuerscheibe 35 durch Lösen des Kupplungsbolzens 38 so verdreht, daß der Kupplungsbolzen 38 nunmehr in die in Fig. 5 unterste Raste 40 des Sperrgliedes 24 eingreift. Dadurch wird in der in Fig. 3 dargestellten Stellung der Arm 36 des Steuergliedes 34 im Uhrzeigersinn nach unten geführt, so daß dieser beim Auflaufen auf die Anlauffläche 31 des nächsten Kurvenstückes 30 die miteinander gekuppelten Scheiben des Sperrgliedes 24 und Steuergliedes 34 im Gegenuhrzeigersinn verschwenkt, so daß der Arm 26 an die Stirnfläche 20 der Tragschiene 6 geführt wird und beim weiteren Hochfahren des unteren Kletterkopfes 14 zur Anlage an eine Stirnfläche 22 des Sperrnockens gelangt, und beim weiteren Hochziehen des Kletterkopfes 14 die Tragschiene 6 mit nach oben nimmt. Das obere Ende des Hydraulikzylinders 13 ist dabei über den oberen Kletterkopf 15 und die Verschiebekonsole 9 starr mit der Wand verbunden. When this movement is complete, the sliding bracket 9 is attached to the next higher scaffold shoe and fastened. The piston rod 16 is now moved into the hydraulic cylinder 13 raised in the previous work step with the climbing head. During this idle stroke, the lower climbing head 14 passes over the locking cams in the same way as the upper climbing head 15 previously. Then the sliding bracket is released from the wall 1 again, so that when the piston rod is extended again, the sliding bracket, supported on the lower climbing head 14, is raised again by the stroke length. Has the scaffold reached its upper end position after several work steps and is it at the Fastened to the wall, the locking members 24 are rotated relative to the control disk 35 by loosening the coupling bolt 38 such that the coupling bolt 38 now engages in the bottom catch 40 of the locking member 24 in FIG. 5. Characterized in the position shown in Fig. 3, the arm 36 of the control member 34 is guided clockwise downward, so that this pivots the coupled disks of the locking member 24 and control member 34 in the counterclockwise direction when approaching the contact surface 31 of the next curve piece 30, so that the arm 26 is guided to the end face 20 of the mounting rail 6 and comes to rest against an end face 22 of the locking cam when the lower climbing head 14 is raised, and takes the mounting rail 6 with it when the climbing head 14 is raised further. The upper end of the hydraulic cylinder 13 is rigidly connected to the wall via the upper climbing head 15 and the sliding bracket 9.
Ist die Kolbenstange 16 eingefahren, so wird in dieser neuen Stellung die Tragschiene 6 wieder in entsprechenden Gerüst- schuhen an der Wand befestigt und die Kolbenstange 16 leer (d. h. ohne Last) ausgefahren. Es wiederholt sich dann der eben beschriebene Arbeitsschritt zum Anheben der Tragschiene . If the piston rod 16 is retracted, in this new position the mounting rail 6 is again fastened to the wall in appropriate framework shoes and the piston rod 16 is extended empty (ie without load). The step just described for lifting the mounting rail is then repeated.
Soll das Gerüst wieder angehoben werden, werden die Kupplungen in den Kletterköpfen wieder gelöst und Sperrglied 24 und Steuerglied 34 so gegeneinander geschwenkt, daß der Kupplungsbolzen 38 nunmehr wieder in die in Fig. 3 oberste Raste 40 einrastet, so daß die beiden Glieder wieder die in Fig. 3 dargestellte Stellung zueinander einnehmen. Dann wird die Verschiebekonsole 9 von dem Gerüstschuh gelöst, in dem sie bis jetzt befestigt war und ein neues Arbeitsspiel durch Be- aufschlagen des Zylinders 13 eingeleitet, bei dem sich wieder der untere Kletterkopf an der nunmehr in der Wand befestigten Tragschiene abstützt und den oberen Kletterkopf 15 samt dem Gerüst 7 nach oben schiebt. If the scaffold is to be raised again, the clutches in the climbing heads are loosened again and the locking member 24 and control member 34 are pivoted against one another in such a way that the coupling bolt 38 now engages again in the top catch 40 in FIG. 3, so that the two members again in Fig. 3 take position to each other. Then the sliding bracket 9 is detached from the scaffold shoe in which it was previously attached and a new work cycle by loading opening of the cylinder 13 initiated, in which the lower climbing head is again supported on the mounting rail now fastened in the wall and pushes the upper climbing head 15 together with the scaffold 7 upwards.
Soll die Tragschiene 6 und hierauf das Gerüst 7 abgesenkt werden, so wird bei an der Wand befestigtem Kletterkopf 15 die Kupplung in den Kletterköpfen so gestellt, daß der Kupplungsbolzen 38 in die unterste Raste eingreift und damit der Arm 26 des Sperrgliedes 24 im Gegenuhrzeigersinn verschwenkt, so daß dieser an einer unteren Stirnfläche 22 zum Eingriff kommt, sobald die Tragschiene 6 von Ihren Gerüstschuhen zur Abwärtsbewegung freigegeben ist. Dann bewegt sich die Tragschiene 6 beim Ausfahren der Kolbenstange 16 mit dem unteren Kletterkopf 14 nach unten. Hierauf wird die Tragschiene 6 wiederum an der Wand befestigt und nach einem Leerhub dieser Arbeitsschritt wiederholt. Befindet sich die Tragschiene 6 in ihrer unteren Endstellung, wird die Kupplung in den Kletterköpfen wieder umgestellt, der obere Kletterkopf 15 von der Wand gelöst und die Kolbenstange 16 wieder eingefahren, wobei sich das mit dem oberen Kletterkopf 15 verbundene Gerüst 7 um den Hub des Hydraulikzylinders 13 absenkt. If the support rail 6 and then the scaffold 7 are to be lowered, the coupling in the climbing heads is set with the climbing head 15 attached to the wall so that the coupling pin 38 engages in the lowest notch and thus the arm 26 of the locking member 24 pivots counterclockwise. so that this comes into engagement on a lower end face 22 as soon as the support rail 6 is released from your scaffold shoes for the downward movement. Then the support rail 6 moves downward when the piston rod 16 is extended with the lower climbing head 14. Thereupon, the mounting rail 6 is in turn fastened to the wall and this work step is repeated after an idle stroke. If the mounting rail 6 is in its lower end position, the clutch in the climbing heads is switched over again, the upper climbing head 15 is detached from the wall and the piston rod 16 is retracted, the frame 7 connected to the upper climbing head 15 being moved by the stroke of the hydraulic cylinder 13 lowers.
Man könnte selbstverständlich nach dem ersten Anhebeschritt die Verschiebekonsole 9 auch an einem Verankerungsbolzen in der Wand befestigen. Dann aber müßte man bei einem Hub von 60 cm alle 60 Zentimeter in der Höhe einen Verankerungsbolzen in der Wand vorsehen, was man vermeidet, wenn in diesen Zwischenschritten die Verschiebekonsole 9 nur an der Tragschiene 6 befestigt wird. Ein Verankerungsbolzen wird hierbei nur im Abstand einer Stockwerkshöhe benötigt, in dessen Gerüstschuh dann das Klettergerüst 7 in seiner angehobenen Endstellung eingehängt wird und an dem die Transportschiene 6 befestigt wird, wenn diese in die angehobene Stellung nachgeführt wird, was im vorliegenden Beispiel ebenfalls in einzelnen Schritten in Größe des Hubes des Hydraulikzylinders 13 erfolgt. Of course, after the first lifting step, the sliding bracket 9 could also be attached to an anchoring bolt in the wall. But then you would have to provide an anchoring bolt in the wall at a stroke of 60 cm every 60 centimeters in height, which is avoided if the sliding bracket 9 is only attached to the mounting rail 6 in these intermediate steps. An anchoring bolt is only required at a distance of one floor height, in the scaffold shoe of which the climbing frame 7 is then raised End position is hooked and to which the transport rail 6 is fastened when it is tracked into the raised position, which in the present example also takes place in individual steps in the size of the stroke of the hydraulic cylinder 13.
Greifen an einem Schalungsabschnitt mehrere derartige Hebevorrichtungen an, so sind die hydraulischen Zylinder 13 durch eine an sich bekannte Vorrichtung miteinander verbunden, die einen exakten Gleichlauf der Hydraulikzylinder 13 gewährleistet. If several such lifting devices act on one formwork section, the hydraulic cylinders 13 are connected to one another by a device known per se, which ensures exact synchronization of the hydraulic cylinders 13.
Selbstverständlich kann die Erfindung auch bei Ausführungsformen verwirklicht sein, bei denen ein Linearantrieb verwendet wird, dessen Hub so groß wie der Betonabschnitt ist. Dann entfallen lediglich die Arbeitsschritte zwischen dem Umstellen der Kupplungen in den Kletterköpfen. Of course, the invention can also be implemented in embodiments in which a linear drive is used, the stroke of which is as large as the concrete section. Then only the work steps between changing the couplings in the climbing heads are omitted.
