Description

Verfahren und Vorrichtung zumMethod and device for Demontieren von DeckenschalungenDisassembly of slab formwork

Die Erfindung betrifft ein Verfahren zum Demontieren von aus mehreren insbesondere randseitig zusammensetzbaren Schaltafeln bestehenden Schaltafeleinheiten von Deckenschalungen, die mit einem Hebezeug untergriffen, aus dem Verbund der Deckenschalung gelöst, abgelassen geschwenkt, und abgesetzt werden. Die Erfindung betrifft ferner eine Vorrichtung zum Ausschalen von Decken, insbesondere zur Durchführung des genannten Verfahrens, mit einem Hebezeug mit einem höhenverstellbaren Arm od. dgl., an dessen freiem Ende eine schwenkbare Halterung zum Erfassen von aus mehreren Schaltafeln besthendene Schaltafeleinheiten angeordnet ist.The invention relates to a method for disassembling formwork units consisting of a plurality of formwork panels, which can be assembled in particular at the edges, from ceiling formworks, which are accessed with a hoist, released from the composite formwork of the ceiling formwork, pivoted down, and set down. The invention further relates to a device for stripping ceilings, in particular for carrying out the above-mentioned method, with a hoist with a height-adjustable arm or the like. At the free end of which a pivotable holder for detecting shuttering panel units consisting of a plurality of shuttering panels is arranged.

Aus der DE-A- 17 59 423 ist bereits ein Verfahren und ein Gerät zum Ausschalen von Schalungen von Betondecken bekannt, bei dem ein Ausschalgerät Schalungsteile erfaßt, absenkt und in eine Schräglage kippt, damit dann das gesamte Gerät durch Türöffnungen in Freie gefahren werden kann. Dabei besteht jedoch das Problem, daß nur relativ kleine Einheiten von Schaltafeln erfaßt werden können, damit diese noch durch eine Türe passen und in ihrer Schräglage gehandhabt, insbesondere demontiert werden können. Ferner ist das Gerät als vertikal in der Länge veränderbarer Mast ausgebildet, der an seinem Ende eine Halterung für die Schaltafeln aufweist. Ein solcher über oft beträchtliche Höhen in Längsrichtung ausfahrbarer Stützmast ist nicht nur schwierig herstellbar, sondern an den Gleitflächen der ineinander schiebbaren Teleskopstangen auch empfindlich.From DE-A-17 59 423 a method and a device for striking formwork of concrete ceilings is already known, in which a stripping device detects formwork parts, lowers and tilts into an inclined position so that the entire device can then be moved into the open through door openings . However, there is the problem that only relatively small units of formwork panels can be detected so that they still fit through a door and can be handled, particularly disassembled, in their inclined position. Furthermore, the device is designed as a vertically variable length mast, which has a holder for the formwork panels at its end. Such a support mast, which can often be extended in the longitudinal direction over considerable heights, is not only difficult to manufacture, but is also sensitive on the sliding surfaces of the telescopic rods which can be pushed into one another.

Darüber hinaus sind aufwendige Arbeitszylinder und/oder Spindeln erforderlich, um eine entsprechend große Höhenverstellung erzielen zu können. Gleichzeitig muß diese vertikal in ihrer Längsrichtung ausfahrbare Stütze sehr stabil sein, wenn genügend große Schalungsteile erfaßt und sogar verkippt werden können sollen, ohne daß die empfindlichen, gegeneinander geführten Teile der längsverstellbaren Stütze darunter leiden. Vor allem ist jedoch die Demontage einer schräg stehenden Schalwand problematisch und auch gefährlich. Andererseits ist ohne weitere Hilfsmittel ein völliges Ablegen der an der höhenverstellbaren Stütze befestigten Schalungsteile nicht möglich, weil diese Stütze in eingefahrenem Zustand eine Mindesthöhe hat.In addition, complex working cylinders and / or spindles are required in order to achieve a correspondingly large height adjustment. At the same time, this support, which can be extended vertically in its longitudinal direction, must be very stable if sufficiently large formwork parts are to be able to be gripped and even tilted without the sensitive, mutually guided parts of the longitudinally adjustable support suffering. Above all, dismantling an inclined formwork wall is problematic and also dangerous. On the other hand, it is not possible to completely put down the formwork parts fastened to the height-adjustable support without further aids, because this support has a minimum height when retracted.

Es besteht deshalb die Aufgabe, ein Verfahren und eine Vorrichtung der eingangs erwähnten Art zu schaffen, mit der das Ausschalen von Deckenschalungen einerseits schnell und sicher durchgeführt werden kann, bei dem also der Vorteil gewahrt bleibt, größere, aus Schaltafeln zusammengesetzte Schalungsteile von der Decke abzunehmen, mit dem aber außerdem eine einfache und ungefährliche Demontage dieser Schalungsteile möglich ist.It is therefore the task of creating a method and a device of the type mentioned at the beginning with which the formwork can be carried out quickly and safely on the one hand, while maintaining the advantage of removing larger formwork parts composed of formwork panels from the ceiling , with which simple and harmless disassembly of these formwork parts is possible.

Zur Lösung dieser Aufgabe besteht das erfindungsgemäße Verfahren darin, daß die Schaltafeleinheiten nach dem Ablösen aus der Deckenschalung teilweise, mindestens um die Hälfte ihrer parallel zu einer Schwenkachse verlaufenden Ausdehnung, abgesenkt und mit ihrer Unterseite nach oben gewendet und danach endgültig abgelegt werden. Nunmehr können sie an ihrer nach oben gerichteten Rückseite demontiert werden, wobei keinerlei Schwerkraft, Stützkräfte od. dgl. an der Schaltafeleinheit mehr wirksam ist. Auch besteht keine Gefahr für die Person, die die Demontage durchführt, da die Schaltafeln bereits am Boden liegen.To achieve this object, the method according to the invention consists in the fact that the shuttering units are partially lowered after being removed from the slab formwork, at least by half of their extent parallel to a pivot axis, and are turned upside down and then finally deposited. Now they can be dismantled on their upward rear side, whereby no gravity, supporting forces or the like is any longer effective on the formwork panel unit. There is also no danger to the person performing the disassembly, since the formwork panels are already on the floor.

Eine Vorrichtung zum Ausschalen von Decken, insbesondere zur Durchführung des vorerwähnten Verfahrens mit einem Hebezeug mit einem höhenverstellbaren Arm od. dgl., an dessen freiem Ende eine schwenkbare Halterung zum Erfassen von aus mehreren Schaltafeln bestehenden Schaltafeleinheiten angeordnet ist, kann erfindungsgemäß dadurch gekennzeichnet sein, daß der höhenverstellbare Arm als schwenkbarer Auslegerarm ausgebildet ist und die Halterung für die Schaltafeleinheiten ihrerseits schwenkbar gelagert ist. Mit einem solchen Auslegerarm läßt sich einerseits sehr leicht eine große Höhe überbrücken, andererseits braucht dieser Arm jedoch für das Absenken nicht in seiner Längsrichtung verstellt zu werden, so daß er keine entsprechend aufwendigen Maschinenteile, Führungen u. dgl. enthalten muß. Auch lassen sich solche Auslegerarme genügend steif ausbilden, um die entsprechenden Gewichte handhaben zu können, während gleichzeitig durch die einseitige Schwenklagerung eines solchen Auslegerarmes z. B. in einer mittleren Position unterhalb des freien Endes genügend Platz für die erfindungsgemäße Umwendebewegung geschaffen wird, die an einem vertikal bleibenden Stützarm nicht gegeben ist.A device for stripping ceilings, in particular for carrying out the above-mentioned method with a hoist with a height-adjustable arm or the like, on the free end of which a pivotable holder is arranged for detecting formwork units consisting of several formwork panels, can be characterized according to the invention in that the height-adjustable arm is designed as a pivotable cantilever arm and the holder for the panel units is in turn pivotally mounted. With such a cantilever arm it is very easy to bridge a great height, on the other hand, however, this arm does not need to be adjusted in its longitudinal direction for lowering, so that it does not have any correspondingly complex machine parts, guides and the like. Like. Must contain. Also, such cantilever arms can be designed to be sufficiently rigid to be able to handle the corresponding weights, while, at the same time, due to the one-sided pivot bearing of such a cantilever arm. B. enough space for the reversing movement according to the invention is created in a middle position below the free end, which is not given on a vertical support arm.

Eine im ganzen mit 1 bezeichnete Vorrichtung dient zum Ausschalen und mindestens zum Vorbereiten der Demontage von Schaltafeln 2 einer Deckenschalung, wobei vermieden werden soll, daß in gefährlicher Weise in großer Höhe die einzelnen Schaltafeln aus dem Schalungsverbund gelöst werden müssen.A device designated as a whole with 1 is used for stripping and at least for preparing the dismantling of formwork panels 2 of a slab formwork, whereby it should be avoided that the individual formwork panels must be released from the formwork assembly in a dangerous manner at great heights.

Die erfindungsgemäße Vorrichtung 1 weist einen schwenkbaren und somit mit seinem freien Ende 3 in der Höhe verstellbaren Auslegerarm 4 auf, der an seinem freien Ende 3 eine ihrerseits schwenkbar gelagerte Halterung 5 für die Schaltafeln 2 hat. In Fig. 1 und 4 ist angedeutetet wie eine aus mehreren Schaltafeln 2 bestehende Schaltafeleinheid an dieser Halterung 5 befestigt ist.The device 1 according to the invention has a pivotable cantilever arm 4, which is therefore adjustable in height with its free end 3, and which has a holder 5 for the control panels 2, which in turn is pivotably mounted on its free end 3. 1 and 4 it is indicated how a formwork consisting of several formwork panels 2 is attached to this holder 5.

Zum Ausschalen kann der Auslegerarm 4 senkrecht oder nahezu senkrecht gestellt werden, während die Halterung 5 ihre etwa horizontale Position behält und einen Schalungsbereich untergreifen kann. Nun können hier Kupplungen oder sonstige Befestigungsmittel betätigt werden, wonach die zu lösende Schaltafeleinheit an ihren Rändern von der übrigen Schalung getrennt wird. Dazu sind im Vergleich zu den insgesamt vorhandenen Verbindungsstellen der Schaltafeln 2 nur relativ wenige Verbindungen in größerer Höhe zu lösen. Danach kann die gesamte Schaltafeleinheit durch Abwärtsschwenken des Auslegerarmes 4 zunächst teilweise abgesenkt werden und zwar mindestens um die Hälfte ihrer parallel zu der Schwenkachse 6 des Auslegerarmes 4 verlaufenden Ausdehnung. Im Ausführungsbeispiel gemäß Fig. 1 und 2 kann dann in dieser Stellung die schwenkbare Halterung 5 unabhängig von dem Auslegerarm 4 um etwa 180° umgewendet werden, so daß die Unterseite der Schaltafeln 2 nach oben gekehrt ist. Danach kann die Schaltafeleinheit durch weiteres Absenken des Auslegerarmes 4 endgültig abgelegt und an der nach oben gerichteten Rückseite demontiert werden. Ein großer Teil der Demontage findet also in ungefährlicher Position am Boden statt.To remove the formwork, the cantilever arm 4 can be placed vertically or almost vertically, while the holder 5 maintains its approximately horizontal position and can reach under a formwork area. Now couplings or other fasteners can be actuated, after which the formwork panel unit to be released is separated at its edges from the rest of the formwork. For this purpose, in comparison to the total connection points of the formwork panels 2, only relatively few connections have to be made at a greater height. Thereafter, the entire formwork panel unit can first be partially lowered by pivoting the cantilever arm 4 downward, namely by at least half of its extent parallel to the pivot axis 6 of the cantilever arm 4. In the exemplary embodiment according to FIGS. 1 and 2, the pivotable holder 5 can then be turned around in this position independently of the extension arm 4 by approximately 180 °, so that the underside of the control panels 2 is turned upwards. Then the formwork panel unit can be finally put down by further lowering the cantilever arm 4 and dismantled on the upward-facing rear side. A large part of the disassembly takes place in a safe position on the floor.

Beim Ausführungsbeispiel nach Fig. 1 und 2 ist also vorgesehen, daß die aus mehreren Schaltafeln 2 bestehende Schaltafeleinheit unmittelbar an dem Hebezeug 1 nach einer Teilabsenkung gewendet und dann endgültig abgesenkt werden. Dabei ist die Halterung 5 als Haltekopf od. dgl. des Auslegerarmes 4 um wenigstens 180° gegenüber einer horizontalen Position schwenkbar, um die gewünschte vollständige Umwendung durchführen zu können. Die Schwenkachse 6 des Auslegerarmes 4 und die des Haltekopfes 5 sind dabei im Ausführungsbeispiel parallel angeordnet. Denkbar wäre jedoch auch, daß der Haltekopf 5 um eine Achse umgewendet werden kann, die etwa in Richtung des Auslegerarmes 4 verläuft.In the embodiment according to FIGS. 1 and 2 it is therefore provided that the formwork unit consisting of several formwork panels 2 is turned directly on the hoist 1 after a partial lowering and then finally lowered. The holder 5 as a holding head or the like. The cantilever arm 4 is pivotable by at least 180 ° relative to a horizontal position in order to be able to carry out the desired complete reversal. The pivot axis 6 of the cantilever arm 4 and that of the holding head 5 are arranged in parallel in the exemplary embodiment. However, it would also be conceivable that the holding head 5 can be turned around an axis which extends approximately in the direction of the cantilever arm 4.

In Fig. 3 ist ein Hebezeug dargestellt, bei dem der Haltekopf 5 von einem zumindest zweiholmigen Auslegerarm 4 a getragen ist, dessen beide Holme 7 parallele Schwenkachsen aufweisen und beim Verschwenken des gesamten Armes 4 a zu einer Parallelversetzung des Haltekopfes 5 führen.In Fig. 3, a hoist is shown in which the holding head 5 is carried by an at least two-arm boom 4 a, the two bars 7 have parallel pivot axes and lead to a parallel displacement of the holding head 5 when pivoting the entire arm 4 a.

In beiden Ausführungsbeispielen sind für den Auslegerarm 4 bzw. 4 a und den Haltekopf 5 Schwenkmittel in Form von Arbeitszylindern 8 vorgesehen, die aber auch als Hubspindeln ausgebildet sein können. Im Ausführungsbeispiel gemäß Fig. 1 sind dabei die Schwenkmittel für den Auslegenarm 4 einerseits und den Haltekopf 5 andererseits unabhängig voneinander betätigbar, während im Ausführungsbeispiel nach Fig. 3 die Betätigung des Auslegerarmes 4 a selbsttätig über die Koppelung 9 der beiden Holme 7 zu einer entsprechenden Gegenverschwenkung des Haltekopfes 5 führt, wodurch dieser die erwähnte Parallel-Position beibehält.In both exemplary embodiments, pivoting means in the form of working cylinders 8 are provided for the cantilever arm 4 or 4 a and the holding head 5, but these can also be designed as lifting spindles. In the embodiment shown in FIG. 1, the pivoting means for the extension arm 4 on the one hand and the holding head 5 on the other hand can be actuated independently of one another, while in the embodiment according to FIG of the holding head 5 leads, whereby this maintains the aforementioned parallel position.

Beim Ausführungsbeispiel nach Fig. 3 ist eine Anpassung an unterschiedliche Höhen schwierig und kann zweckmäßigerweise durch einen an dem Haltekopf 5 höhenverstellbar anbringbaren Aufsetztisch 5 b bewerkstelligt werden. Demgegenüber ist im Ausführungsbeispiel nach Fig. 1 eine einfacherere Anpaßbarkeit dadurch möglich, daß der Auslegrarm 4 in seiner Länge verstellbar, insbesondere teleskopartig ausziehbar ist. Gegenüber einem vertikalen, zum Erreichen der Decke teleskopartig ausfahrbaren Stützarm braucht diese Verlängerungsmöglichkeit jedoch nicht mit derartig sorgfältigen Toleranzen und vor allem nicht mit Antriebsmitteln versehen zu sein. Vielmehr können ineinandergesteckte Rohrstücke mit Querlochungen 10 und entsprechenden Querbolzen Verwendung finden, so daß insgesamt eine sehr einfach aufgebaute Vorrichtung entsteht, bei der dennoch auf einfache Weise unterschiedlich große Höhen berücksichtigt werden können. Zusätzlich kann der Haltekopf 5 mit seiner zentralen Stütze 5 a beispielsweise über ein Gewinde 11 höhenverstellbar an einem Ansatz 12 des Schwenklagers 13 am freien Ende 3 des Auslegerarmes 4 angreifen. Dadurch können innerhalb der Abstände der Lochungen 10 liegende Höhenanpassungen durchgeführt werden.In the exemplary embodiment according to FIG. 3, adaptation to different heights is difficult and can expediently be accomplished by a mounting table 5 b which can be attached to the holding head 5 in a height-adjustable manner. In contrast, in the exemplary embodiment according to FIG. 1, simpler adaptability is possible in that the extension arm 4 is adjustable in length, in particular can be extended telescopically. Compared to a vertical support arm that can be extended telescopically to reach the ceiling, this extension option need not be provided with such careful tolerances and, above all, not with drive means. Rather, nested pieces of pipe with cross holes 10 and corresponding cross bolts can be used, so that overall a very simple device is created, in which heights of different sizes can be taken into account in a simple manner. In addition, the holding head 5 can engage with its central support 5 a, for example by means of a thread 11 adjustable in height, on a shoulder 12 of the pivot bearing 13 at the free end 3 of the cantilever arm 4. As a result, height adjustments lying within the spacings of the perforations 10 can be carried out.

Bei beiden Ausführungsbeispielen erkennt man, daß der schwenkbare Auslegerarm 4 bzw. 4 a an einem im Ausführungsbeispiel jeweils verfahrbaren Gestell 14 gelagert ist, wobei dieses verfahrbare Gestell 14 lenkbare, vorzugsweise mit Nachlauf versehene Räder 15 aufweisen kann. Dadurch ist nach dem Abnehmen einer Schaltafeleinheit auch eine Ortsveränderung möglich, um die Schaltafeleinheit für die Demontage an einen möglichst günstigen Ort zu bringen. Darüber hinaus ergibt sich so die Möglichkeit, die abgenommene Schaltafeleinheit zu einem anderen Bereich einer Baustelle zu bringen und ohne Demontage gleich wieder als Deckenschalungs-Teil zu verwenden.In both exemplary embodiments, it can be seen that the pivotable cantilever arm 4 or 4 a is mounted on a frame 14 which is respectively movable in the exemplary embodiment, this movable frame 14 having steerable wheels 15, preferably provided with caster. As a result, after removing a formwork panel unit, a change of location is also possible in order to move the formwork panel unit to a place that is as favorable as possible for disassembly bring. In addition, there is the possibility of taking the removed formwork panel unit to another area of a construction site and of using it as part of the ceiling formwork again without dismantling.

Im übrigen sei erwähnt, daß mit Hilfe der erfindungsgemäßen Vorrichtung 1 auch das Einschalen von Decken unter Umständen dadurch erleichtert werden kann, daß größere Schaltafeleinheit am Boden montiert und dann mit der Vorrichtung 1 erfaßt, umgewendet und in ihre Position gebracht werden können.Moreover, it should be mentioned that with the help of the device 1 according to the invention, the shuttering of ceilings can be facilitated under certain circumstances by mounting larger panel units on the floor and then using the device 1 to detect them, turn them over and bring them into position.

Zu der Vorrichtung 1 gemäß dem Ausfuhrungsbeispiel nach Fig. 3 gehört erfindungsgemäß und nach einem Merkmal der Erfindung von eigener schutzwürdiger Bedeutung eine in den Fig. 4 bis 6 näher dargestellte Wendevorrichtung 16, die im Bereich des abschwenbarn Auslegerarmes 4 a angeordnet wird und Auflager bzw. Aufnahmeöffnungen 17 für an den Schaltafeleinheiten 2 anbringbare Schwenkbolzen 18 hat. Eines der Auflager 17 und ein Schwenkbolzen 18 sind dabei in Fig. 6 gesondert dargestellt.The device 1 according to the exemplary embodiment according to FIG. 3 includes, according to the invention and according to a feature of the invention of its own worthy protection, a turning device 16 shown in FIGS. 4 to 6, which is arranged in the region of the swing-out arm 4 a and supports or Has receiving openings 17 for pivot pins 18 attachable to the panel units 2. One of the supports 17 and a pivot pin 18 are shown separately in FIG. 6.

Diese ebenfalls zur Erfindung gehörige Wendevorrichtung 16, auf der auch Schaltafeleinheiten 2 mit Hilfe einer Vorrichtung 1 gemäß den Fig. 1 und 2 abgelegt werden kann, ist durch ein aus zwei unabhängigen Teilen bestehendes Gerüst gebildet, welches mit einem Fahrgestell 19 mit vorzugsweise lenkbaren Rädern 20 versehen ist. Somit kann eine Schaltafeleinheit 2 nach dem Absetzen in dieser Wendevorrichtung 16 ebenfalls an einen anderen Ort übergeführt und dort endgültig demontiert oder einer neuen Verwendung zugeführt werden.This turning device 16, which is also part of the invention and on which formwork panel units 2 can also be placed with the aid of a device 1 according to FIGS. 1 and 2, is formed by a scaffold consisting of two independent parts, which has a chassis 19 with preferably steerable wheels 20 is provided. Thus, after being set down in this turning device 16, a formwork panel unit 2 can also be transferred to another location and finally dismantled there or be used again.

Darüber hinaus läßt sich so die Wendevorrichtung 16 selbst ebenso wie das Hebezeug der Vorrichtung 1 leicht an die unterschiedlichen Stellen anpassen, an denen Ausschal- oder eventuell Einschalarbeiten durchgeführt werden müssen.In addition, the turning device 16 itself as well as the lifting device of the device 1 can be easily adapted to the different locations at which stripping or possibly stripping work must be carried out.

Zu der erfindungsgemäßen Vorrichtung gehört die in Fig. 6 deutlich dargestellte, an den Schaltafelrändern der zu handhabenden Schaltafeleinheit 2 anbringbare Schiene 21 mit einem von den Schaltafeln 2 parallel zur Schalhaut abstehenden Bolzen 18, wobei jeweils an zwei einander gegenüberliegenden Rändern solche Schienen 21 mit Bolzen 18 anzubringen sind, die dann in entsprechende Aufnahmeöffnungen bzw. Auflager 17 der Wendevorrichtung 16 passen. Werden beispielsweise zwei derartige Wendevorrichtungen 16 einander gegenübergestellt, können die voneinander wegragenden Bolzen 18 in die entsprechenden Auflager 17 eingelegt werden, so daß danach die Wendung der Schaltafeleinheit erfolgen kann. Die an den Schaltafeln 2 anbringbaren Schwenkbolzen 18 haben dabei an ihrem freien Ende einen Kopf 21 a, der die Stirnseite der Aufnahmeöffnungen 17 in Gebrauchsstellung hintergreifen kann. Dies wird anhand der Fig. 6 in Verbindung mit Fig. 4 deutlich, wo im oberen Bereich in gestrichelter Darstellung die Anordnung einer eingehängten Schaltafeleinheit 2 angedeutet ist.The device according to the invention includes the rail 21, clearly shown in FIG. 6, which can be attached to the panel edges of the panel unit 2 to be handled, with a bolt 18 projecting from the panel 2 parallel to the formlining, such rails 21 with bolts 18 each at two opposite edges are to be attached, which then fit into corresponding receiving openings or supports 17 of the turning device 16. If, for example, two such turning devices 16 are juxtaposed, the bolts 18 projecting from one another can be inserted into the corresponding supports 17, so that the panel unit can then be turned. The pivot pins 18 which can be attached to the formwork panels 2 have at their free end a head 21 a which can engage behind the end face of the receiving openings 17 in the use position. This becomes clear on the basis of FIG. 6 in connection with FIG. 4, where the arrangement of a suspended formwork panel unit 2 is indicated in the upper area in dashed lines.

Die Schwenkbolzen 18 können an ihrem Kopf 21 a und/oder an ihrem dem Kopf abgewandten Bereich 22 einen zu dem Auflager 17 gerichteten Konus aufweisen, der beim Einsetzen eine selbsttätige Zentrierung zwischen dem Bolzen 18 und der Wendevorrichtung 16 bewirkt. Auch dabei ist es vorteilhaft, daß die beiden gemeinsam eine Schaltafeleinheit aufnehmenden Wendevorrichtungen 16 fahrbar sind, weil sie den von dem Konus und der Schwerkraft ausgeübten Kräften gut folgen können.The pivot pins 18 can have on their head 21 a and / or on their area 22 facing away from the head a cone directed towards the support 17, which causes an automatic centering between the pin 18 and the turning device 16 when inserted. Here, too, it is advantageous that the two turning devices 16, which together receive a formwork panel unit, are mobile, because they can follow the forces exerted by the cone and gravity well.

Die Auflager bzw. Aufnahmeöffnungen 17 der Wendevorrichtungen 16 sind höhenverstellbar und vorzugsweise mittels Arbeitszylindern 23 einstellbar und festlegbar. Um dabei mit einem relativ kleinen Hub an dem Arbeitszylinder 23 auszukommen, ist im Ausführungsbeispiel vorgesehen, daß die Auflager 17 für die Schwenkbolzen 18 der Wendevorrichtungen 16 in einem Wendegestell 24 höhenverstellbar geführt sind und daß an diesen Auflagern 17 Zugelemente 25, insbesondere Ketten angreifen, die über ein oberes Umlenkrad 28 zu dem bewegbaren Teil, nämlich der Kolbenstange 27 des Arbeitszylinders 23 führen. Wird nun dieser Arbeitszylinder betätigt, ergibt sich gegenüber seinem Hub praktisch eine Verdoppelung der Hebelewegung bzw. die Auflager 17 können auch unter die höchste Position der Kolbenstange bis zum Boden abgesenkt werden. Die Kette 25, die in mittlerer Höhe beispielsweise an einer Platte 28 verankert ist, hängt dann in eingefahrener Position des Arbeitszylinders über das entsprechend nun tief stehende Umlenkrad 26 nach unten.The supports or receiving openings 17 of the turning devices 16 are height-adjustable and preferably adjustable and fixable by means of working cylinders 23. In order to get by with a relatively small stroke on the working cylinder 23, it is provided in the exemplary embodiment that the supports 17 for the pivot bolts 18 of the turning devices 16 are guided such that they can be adjusted in height in a turning frame 24 and that 17 tension elements 25, in particular chains, act on these supports Lead via an upper deflection wheel 28 to the movable part, namely the piston rod 27 of the working cylinder 23. If this working cylinder is now actuated, the stroke movement is practically doubled compared to its stroke, and the supports 17 can also be lowered to the floor below the highest position of the piston rod. The chain 25, which is anchored at a medium height, for example, to a plate 28, then hangs downward in the retracted position of the working cylinder via the correspondingly now lower deflection wheel 26.

Die Arbeitszylinder 23 und auch 8 der Wendevorrichtungen 16 und der schwenkbare Auslegerarm 4 können dabei mit einer Handpumpe betätigbar sein, so daß die ganze Vorrichtung unabhängig von irgendwelchen Kraftanschlüssen wird.The working cylinders 23 and also 8 of the turning devices 16 and the pivotable cantilever arm 4 can be actuated with a hand pump, so that the entire device is independent of any power connections.

Um eine Schaltafeleinheit 2 auf zwei Wendevorrichtungen 16 bequem absetzen zu können und gleichzeitig den konstruktiven Aufwand, aber auch den Platzbedarf für diese Wendevorrichtungen 16 so gering wie möglich zu halten, bestehen die Wendevorrichtungen 16 im Ausführungsbeispiel aus zwei spiegelsymmetrisch zueinander aufstellbaren, unabhängig voneinander bewegbaren Gerüsten, die zueinander gerichtete Füße 29 od. dgl. Auflager mit den Rädern 20 aufweisen, die unter den Auslegerarm 4 oder 4 a des Hebezeuges 1 passen. Dabei sind diese Füße 29 niedriger als es z. B. ein Kantholz od. dgl. ist, so daß parallel zu diesen Auflagerfüßen 29 Kanthölzer gelegt werden können, auf denen dann die von diesen Wendevorrichtungen 16 erfaßte Schaltafeleinheit 2 nach dem Umwenden endgültig abgelegt werden kann. Die Wendevorrichtungen 16 können dann beidseitig herausgezogen und weggefahren und einer weiteren Verwendung zugeführt werden. Bei Benutzung solcher Wendevorrichtungen 16 werden also die Schaltafeleinheiten 2 mit dem Hebezeug 1 zunächst auf diesen Wendevorrichtungen 16 abgelegt, auf diesen gewendet und dann endgültig abgesenkt. Dabei kann die Wendung selbst praktisch von Hand erfolgen, weil die Schaltafeleinheiten aufgrund der mittig angeordneten Bolzen 18 sehr leicht gedreht werden können. Die Befestigung der Bolzen 18 kann mit Hilfe schlüssellochartiger Lochungen 30 erfolgen, die zu entsprechenden Lochungen an den stirnseitigen Rändern der Schaltafeln 2 passen und den Einsatz derselben Befestigungselemente erlauben, mit denen die Schaltafeln 2 auch untereinander gekuppelt werden können.In order to be able to conveniently place a formwork panel unit 2 on two turning devices 16 and at the same time to keep the design effort, but also the space requirement for these turning devices 16 as low as possible, the turning devices 16 in the exemplary embodiment consist of two scaffolds which can be set up in mirror symmetry and can be moved independently of one another, the facing feet 29 or the like. Bearings with the wheels 20 which fit under the cantilever arm 4 or 4 a of the hoist 1. These feet 29 are lower than z. B. a squared timber or the like. So that 29 squared lumber can be placed parallel to these support feet, on which the formwork unit 2 detected by these turning devices 16 can be finally deposited after turning. The turning devices 16 can then be pulled out on both sides and moved away and used for further use. When using such turning devices 16 so Panel units 2 with the hoist 1 first placed on these turning devices 16, turned on them and then finally lowered. The turn itself can be done practically by hand because the formwork units can be rotated very easily due to the centrally arranged bolts 18. The bolts 18 can be fastened with the aid of keyhole-type perforations 30 which match corresponding perforations on the front edges of the formwork panels 2 and allow the use of the same fastening elements with which the formwork panels 2 can also be coupled to one another.

Insgesamt ergibt sich ein Verfahren und eine Vorrichtung, mit der vor allem Deckenschalungen demontiert werden können, wobei in vorteilhafter Weise ein großer Teil der Demontage auf den flachen Boden verlagert werden kann, so daß das Auseinandernehmen dieser Schaltafeln 2 ungefährlich und einfach ist. Dabei begnügt sich die erfindungsgemäße Vorrichtung nicht damit, Schaltafein aus größerer Höhe abzusenken und zu kippen, sondern sie erlaubt aufgrund der speziellen Ausbildung der Vorrichtung ein völliges Umwenden, wodurch die Befestigungsstellen nach dem Ablegen gut zugänglich sind, aber keine Stützkräfte, Halterungen od. dgl. mehr erforderlich sind, da die Schaltafeln ungefährlich flach auf dem Boden liegen.Overall, there is a method and a device with which, above all, ceiling formwork can be dismantled, with a large part of the dismantling advantageously being able to be shifted onto the flat floor, so that the dismantling of these formwork panels 2 is harmless and simple. The device according to the invention is not satisfied with lowering and tilting the switchboard from a greater height, but rather, due to the special design of the device, allows it to be completely turned around, as a result of which the attachment points are easily accessible after being put down, but no supporting forces, holders or the like. more are required, since the formwork panels lie safely on the floor.

Durch die Verwendung eines schwenkbaren Auslegerarmes bzw. einer Wendevorrichtung werden dabei scheinbar widersinnige Forderungen gleichzeitig erfüllt, einerseits möglichst große Schaltafeleinheiten absenken zu können, diese aber dennoch völlig umwenden und ablegen zu können, um sie in einer ungefährlichen Position am Boden auseinandernehmen zu können.By using a swiveling boom arm or a turning device, apparently contradictory requirements are met at the same time, on the one hand to be able to lower formwork units that are as large as possible, but to be able to completely turn them over and put them down so that they can be taken apart in a safe position on the floor.

Ein großer Vorteil der erfindungsgemäßen Vorrichtung besteht auch darin, daß mit Hilfe der schwenkbaren Halterung 5 auch Schaltafeln von einer geschalten Wand abgenommen oder an dieser angebracht werden können, wobei dann die Halterung gegenüber der Darstellung in Fig. 1 um 90° verschwenkt anzuwenden ist. Darüber hinaus können bei solchen Schalungen, bei denen Schaltafeln wahlweise für Decken und für Wände geeignet sind, die Schaltafeln unmittelbar von der Wand abgenommen und in den Bereich der Decke gehoben werden. Somit wird mit der erfindungsgemäßen Vorrichtung nicht nur das Aus- und Einschalen von Decken, sondern auch von insbesondere relativ hohen Wänden vereinfacht und die oberen Schaltafeln einer Wandung können sofort umgesetzt werden, um eine darüber befindliche Decke zu schalen.A great advantage of the device according to the invention is also that, with the aid of the pivotable holder 5, switchboards can also be removed from or attached to a switched wall, the holder then being used pivoted by 90 ° with respect to the illustration in FIG. 1. In addition, in the case of formwork in which formwork panels are optionally suitable for ceilings and walls, the formwork panels can be removed directly from the wall and lifted into the area of the ceiling. Thus, the device according to the invention not only simplifies the removal and removal of formwork from ceilings, but also, in particular, relatively high walls, and the upper formwork panels of a wall can be immediately implemented in order to form a ceiling located above it.
