Description

Die Erfindung betrifft ein Klettergerüst zum Einschalen zu betonierender Wände, mit einem an dem bereits betonierten Teil der Wand lösbar anzubringenden Rahmen, der eine obere Arbeitsbühne aufweist, über der eine Schalplatte schwenkbar und aus der Arbeitsposition zurückstellbar angebracht ist.The invention relates to a climbing frame for encasing walls to be concreted, with a frame which can be releasably attached to the already concreted part of the wall and which has an upper work platform above which a formwork plate can be pivoted and can be reset from the working position.

Klettergerüste werden zum Errichten hoher Bauwerke wie Sendetürme, Kühltürme, Brückenpfeiler und dergleichen verwendet. Zum Einschalen wird das Klettergerüst zunächst an den bereits fertiggestellten obersten Teil des Betonbauwerkes mittels dort vorgesehener Verankerungselemente lösbar angehängt. Sind die Bewehrungsarbeiten des zu betonierenden nächsten Teiles oder Abschnittes des Bauwerkes beendet, wird die über der obersten Arbeitsbühne angeordnete Schalplatte in die Betriebsposition gebracht, in der die an der Schalplatte befindliche Schalhaut mit der Oberfläche des bereits fertig-gestellten Teiles des Betonbauwerkes fluchtet. In dieser Position wird die Schalplatte festgestellt, woraufhin betoniert werden kann. Nach Verfestigen des Betons wird die Schalplatte aus der Betriebsposition zurückbewegt, bevor das Klettergerüst einen Abschnitt höher gesetzt wird. Befindet sich die Schalplatte in der zurückgestellten Position, kann die Oberfläche der Schalhaut gereinigt und für den nächsten Betoniervorgang vorbereitet werden.Climbing frames are used to erect tall structures such as transmission towers, cooling towers, bridge pillars and the like. To form the formwork, the climbing frame is first detachably attached to the already completed uppermost part of the concrete structure by means of anchoring elements provided there. When the reinforcement work of the next part or section of the structure to be concreted is finished, the formwork panel arranged above the uppermost work platform is brought into the operating position in which the formwork skin on the formwork panel is flush with the surface of the already completed part of the concrete structure. In this position, the formwork panel is fixed, whereupon it is concreted can. After the concrete has solidified, the formwork sheet is moved back from the operating position before the climbing frame is set one section higher. If the formwork sheet is in the reset position, the surface of the formwork skin can be cleaned and prepared for the next concreting process.

Es ist bekannt, die Schalplatte auf einem Fahrgestell anzuordnen, das sich auf parallelen Trägern der oberen Arbeitsbühne des Rahmens abstützt. Hierbei ruht die Last der Schalplatte auf den Trägern der oberen Arbeitsbühne, die entsprechend der jeweiligen Position der Schalplatte an unterschiedlichen Stellen am stärksten belastet werden, so daß großereBiegemomente im Rahmen nicht zu vermeiden sind. Ein weiterer Nachteil besteht darin, daß der Druck des frisch gegossenen Betons die Schalplatte von der Wand wegzudrücken trachtet, so daß die Schalplatte bzw. deren Fahrgestell sehr sorgfältig in der Betriebsposition verriegelt werden muß.It is known to arrange the formwork panel on a chassis which is supported on parallel supports of the upper work platform of the frame. The formwork plate rests on the supports of the upper work platform, which are subjected to the greatest loads at different points depending on the respective position of the formwork plate, so that larger bending moments in the frame cannot be avoided. Another disadvantage is that the pressure of the freshly poured concrete tries to push the formwork panel away from the wall, so that the formwork panel or its chassis must be locked very carefully in the operating position.

Der Erfindung liegt die Aufgabe zugrunde, ein verbessertes Klettergerüst zum Einschalen zu betonierender Wände zu schaffen, bei dem die Schalplatte keine . Biegemomente auf den Rahmen ausübt und in der Betriebsposition mit ihrem Gewicht gegen die zu betonierende Wand drückt.The invention has for its object to provide an improved climbing frame for formwork walls to be concreted, in which the formwork panel none. Exerts bending moments on the frame and in the operating position presses their weight against the wall to be concreted.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Schalplatte auf am Rahmen schwenkbar gelagerten, etwa senkrecht stehenden Stützen ruht. Auf diese Weise kann die Schalplatte so am Rahmen gelagert werden, daß ihr Gewicht etwa zentral in den Rahmen eingeleitet wird. Dadurch ergibt sich der weitere Vorteil, daß die Schalplatte beim Verstellen über einen Kreisbogen bewegt wird und dementsprechend einen Totpunkt überwinden muß, der sich zwischen ihrer Betriebsposition und der zurückgestellten Position befindet, so daß das Gewicht der Schalplatte sowohl in der Betriebsposition als auch in der zurückgestellten Position in die dabei erreichbare Extremstellung wirkt, so daß die Schalplatte also mit ihrem Gewicht in der Betriebsposition gegen den zu betonierenden Wandabschnitt drückt. Dementsprechend braucht die Schalplatte in der Betriebsposition nicht so fest wie bisher gesichert zu werden, weil ihr Gewicht dem Druck des frischen Betons entgegenwirkt. In der zurückgestellten Position braucht die Schalplatte nicht verriegelt zu werden, weil sie sich nicht unabsichtlich aus dieser Position in die Betriebsposition bewegt, wie dies bei Abstützung auf einem Fahrgestell der Fall sein Könnte.This object is achieved in that the formwork plate rests on pivotally mounted, approximately vertical supports on the frame. In this way the formwork panel can be stored on the frame so that its weight is introduced approximately centrally into the frame. This has the further advantage that the formwork plate is moved over a circular arc during adjustment and accordingly has to overcome a dead center located between its operating position and the reset position, so that the weight of the formwork plate both in the operating position and in the reset position Position acts in the extreme position that can be reached, so that the formwork panel presses with its weight in the operating position against the wall section to be concreted. Accordingly, the formwork panel does not need to be secured as firmly in the operating position as before, because its weight counteracts the pressure of the fresh concrete. In the reset position, the formwork plate does not need to be locked because it does not inadvertently move from this position into the operating position, as might be the case when it is supported on a chassis.

Vorzugsweise sind die die Schalplatte tragenden Stützen unterhalb der oberen Arbeitsbühne am Rahmen angelenkt, so daß die Abstützung der Schalplatte im Bereich oder nahe des Schwerpunktes des Rahmens erfolgen kann.Preferably, the supports carrying the formwork panel are hinged to the frame below the upper work platform, so that the formwork panel can be supported in the region or near the center of gravity of the frame.

Zusätzlich können die Stützen mittels Streben an horizontalen Trägern des Rahmens geführt sein, wobei jede Strebe mit einem Ende an das obere Ende einer Stütze und mit dem anderen Ende an einen Schlitten angelenkt sein kann, der auf einem Träger verschiebbar sitzt. Dieser Schlitten kann auf einem Träger der oberen Arbeitsbühne sitzen. Bei dieser Ausführungsform der Erfindung ist die Stütze also zusätzlich mit einem horizontal verstellbaren Schlitten verbunden, der eine zusätzliche Abstützung bildet, damit die Schalplatte beim Verstellen nicht kippt. Außerdem dient der Schlitten als Stellelement für die Schalplatte.In addition, the supports can be guided by means of struts on horizontal supports of the frame, each strut being articulated at one end to the upper end of a support and at the other end to a slide can be that slidably sits on a carrier. This sledge can sit on a carrier of the upper work platform. In this embodiment of the invention, the support is therefore additionally connected to a horizontally adjustable slide, which forms an additional support, so that the formwork plate does not tip over during adjustment. The slide also serves as an actuator for the formwork panel.

Die Schalplatte ist vorzugsweise höheneinstellbar auf den Stützen gelagert, um Schrägstellungen ausgleichen bzw. vermeiden zu können.The formwork panel is preferably mounted on the supports in such a way that it can be adjusted in height in order to compensate for or avoid inclined positions.

Zum Verstellen des Schlittens ist nach einem weiteren Merkmal der Erfindung dieser mit wenigstens einer Rast und vorzugsweise mit mehreren Rasten versehen, in die ein schwenkbar am Rahmen gelagerter Hebel einrückbar ist. Außerdem kann der Schlitten mit einer Fußraste versehen sein. Zum Verstellen des Schlittens und damit der Schalplatte wird der Hebel in eine Rast eingerückt und dann verschwenkt, wodurch der Schlitten auf dem betreffenden Träger des Rahmens verschoben wird. Die Fußtaste ist zweckmäßig so ausgebildet, daß sie zum Lösen betätigt werden muß und sich feststellt, wenn sie nicht betätigt wird. Zum Umsetzen des Hebels in eine andere Rast oder überhaupt zum Anhalten des Schlittens braucht die Bedienungsperson die Fußraste nur loszulassen, wodurch sie sofort wirksam wird und den Schlitten anhält. Soll der Schlitten weiter bewegt werden, muß man lediglich erneut auf die Fußraste treten.To adjust the slide, according to a further feature of the invention, it is provided with at least one catch and preferably with a plurality of catches into which a lever which is pivotably mounted on the frame can be inserted. The carriage can also be provided with a footrest. To adjust the slide and thus the formwork plate, the lever is engaged in a detent and then pivoted, whereby the slide is moved on the relevant carrier of the frame. The foot switch is expediently designed so that it must be operated to release it and is determined when it is not operated. To move the lever to another stop or to stop the slide at all, the operator only needs to let go of the footrest, which will take effect immediately and stop the slide. If the carriage is to be moved further, you only have to step on the footrest again.

Nach einem weiteren Merkmal der Erfindung ist der Schlitten mit zwei in seiner Verschieberichtung spannbaren Federn versehen, von denen eine am Ende der Vorschiebebewegung und die andere am Ende der Rückschiebebewegung vom Schlitten gespannt wird. Auf diese Weise kann die Anfangsbewegung des Schlittens und damit der Schalplatte durch Federkraft unterstützt werden, während am Ende des Verstellweges die Bewegung durch das Spannen der eingesetzten Feder abgebremst wird.According to a further feature of the invention, the slide is provided with two springs which can be tensioned in its direction of displacement, one of which is tensioned by the slide at the end of the advancing movement and the other at the end of the pushing-back movement. In this way, the initial movement of the slide and thus the formwork plate can be supported by spring force, while at the end of the adjustment path the movement is braked by tensioning the spring used.

Durch die Erfindung wird ein Klettergerüst geschaffen, bei dem die Schalplatte besonders vorteilhaft abgestützt und auch einfach zu verstellen ist, hingegen in den beiden vorgesehenen Extremstellungen wenigstens teilweise aufgrund ihres Gewichtes gehalten wird.The invention creates a climbing frame in which the formwork panel is supported in a particularly advantageous manner and is also easy to adjust, on the other hand it is held at least in part in the two intended extreme positions due to its weight.

In der Zeichnung ist ein Ausführungsbeispiel des erfindungsgemäßen Klettergerüstes in Seitenansicht in der Betriebsposition an einem bereits betonierten Wandabschnitt hängend schematisch dargestellt.In the drawing, an embodiment of the climbing frame according to the invention is schematically shown in a side view in the operating position hanging from an already concreted wall section.

Das Klettergerüst hat einen Rahmen 1 mit senkrechten Trägern 2, horizontalen Trägern 3, 4 und 5 und zwischen diesen angebrachten Diagonalstreben 6 und 7. Auf den obersten Trägern 3 ist eine obere Arbeitsbühne 8 und auf den untersten Trägern 5 eine untere Arbeitsbühne 9 vorgesehen. Die obersten Träger 3 sind mittels einer Konsole 10 lösbar an jeweils einen Halter 11 angehängt, der in den bereits fertiggestellten Wandabschnitt 12 einbetoniert ist. Die darunter befindlichen Träger 4 und5 stützen sich gegen Kanthölzer 13 und 14 ab, welche auf dem bereits betonierten Wandabschnitt 12 angeordnet sind.The climbing frame has a frame 1 with vertical supports 2, horizontal supports 3, 4 and 5 and diagonal braces 6 and 7 attached between them. An upper work platform 8 is provided on the uppermost supports 3 and a lower work platform 9 is provided on the lowest supports 5. The uppermost beams 3 are detachably attached to a holder 11 by means of a bracket 10, which is concreted into the already completed wall section 12. The supports 4 and 5 below are supported against squared timbers 13 and 14, which are arranged on the already concreted wall section 12.

Zwischen den nebeneinander liegenden Trägern 3 bzw. 5 sind querverlaufende Kanthölzer 15 bzw. 16 angeordnet, welche die Querverbindung des Klettergerüstes herstellen und zum Abstützen der Arbeitsbühnen 8 bzw.'9 dienen. In der Seitenansicht der Zeichnung ist jeweils nur einer der Träger 3, 4 und 5 zu erkennen, weil die anderen, parallel dazu liegenden Träger ebenso wie weitere Stützen 2 verdeckt sind.Transverse squared timbers 15 and 16 are arranged between the supports 3 and 5 lying next to one another, which produce the cross connection of the climbing frame and serve to support the working platforms 8 and 9. In the side view of the drawing, only one of the beams 3, 4 and 5 can be seen in each case, because the other beams lying parallel thereto, as well as further supports 2, are covered.

Die obere Arbeitsbühne 8 steht nach hinten über die senkrechten Stützen 2 des Rahmens 1 über und ist mit diesem überstehenden Ende mittels Streben 17 abgestützt. Zur rückwärtigen Begrenzung der oberen Arbeitsbühne 8 ist ein Geländer 18 vorgesehen. Oberhalb der oberen Arbeitsbühne 8 ist am Rahmen eine Schalplatte 19 mit an ihrer Vorderseite befindlicher Schalhaut 20 angeordnet. Die Schalplatte 19 ruht mittels zwei Stellschrauben 21, von denen in der Zeichnung nur eine zu erkennen ist, höheneinstellbar auf zwei etwa senkrecht verlaufenden Stützen 22, die mit ihrem unteren Ende jeweils an einen der mittleren Träger 4 des Rahmens 1 angelenkt sind. Der Anlenkpunkt 23 liegt zwischen den Enden des betreffenden Trägers 4 und kann so gelegt werden, daß er sich im Bereich des Schwerpunktes des Rahmens 1 befindet.The upper working platform 8 projects over the vertical supports 2 of the frame 1 and is supported with this projecting end by means of struts 17. A railing 18 is provided for the rearward limitation of the upper working platform 8. Above the upper work platform 8, a formwork plate 19 with formwork skin 20 located on its front is arranged on the frame. The formwork plate 19 rests by means of two set screws 21, of which only one can be seen in the drawing, adjustable in height on two approximately vertically extending supports 22, each of which is hinged at its lower end to one of the central supports 4 of the frame 1. The articulation point 23 lies between the ends of the carrier 4 in question and can be placed in such a way that it is in the region of the center of gravity of the frame 1.

Am oberen Ende jeder Stütze 22 ist ein Kopfstück 24 vorgesehen, mit dem die Stellschraube 21 gelenkig verbunden ist, so daß eine Gelenkverbindung zwischen der Schalplatte 19 und den diese tragenden Stützen 22 gegeben ist.At the upper end of each support 22, a head piece 24 is provided, with which the set screw 21 is articulated, so that an articulated connection between the Formwork panel 19 and the supports 22 which support it.

An das Kopfstück 22 ist das eine Ende einer Strebe 25 angelenkt, deren anderes Ende mit einem Bock 26 gelenkig verbunden ist, der sich am hinteren Ende eines. Schlittens 27 befindet, welcher auf .dem obersten Träger 3 in Längsrichtung desselben verschiebbar ruht. An den Bock 26 ist außerdem das untere Ende einer Diagonalstrebe 28 angelenkt, deren nicht dargestelltes oberes Ende an der Rückseite der nur teilweise in der Zeichnung gezeigten Schalplatte 19 angebracht ist.One end of a strut 25 is articulated to the head piece 22, the other end of which is connected in an articulated manner to a bracket 26 which is located at the rear end of a strut. Carriage 27 is located, which rests on the uppermost carrier 3 in the longitudinal direction of the same. The lower end of a diagonal strut 28 is also articulated to the bracket 26, the upper end, not shown, of which is attached to the rear of the formwork panel 19 which is only partially shown in the drawing.

Jeder Träger 3 besteht aus zwei parallelen U-Profilen, die im Abstand voneinander angeordnet und im mittleren Bereich mittels Querplatten 29 und 30 untereinander verbunden sind. Der Schlitten 27 weist eine auf der Oberseite des Trägers 3 aufliegende und die beiden U-Profile überbrückende Platte 31 auf, an deren Unterseite zwei zwischen die U-Profile ragende Zungen 32 und 33 angebracht sind. Zwischen diesen Zungen32 und 33 erstreckt sich eine Stange 34, auf der zwei Druckfedern 35 und 36 sitzen, die mit einem Ende jeweils an einer der Zungen 32 bzw. 33 befestigt sind. Mit dem anderen Ende kann die Druckfeder 35 in Anlage an die Querplatte 29 und die Druckfeder 36 in Anlage an die Querplatte 30 kommen. In der dargestellten Position des Schlittens 27 liegt die Druckfeder 35 an der Querplatte 29 an und ist zwischen dieser und der Zunge 32 zusammengedrückt, während die Druckfeder 36 entspannt ist, weil sie nicht mit der Querplatte 30 in Kontakt steht, Wird der Schlitten hingegen in die andere Position zurückgestellt, in der die Schalplatte 19 aus der Arbeitsposition ausgerückt ist, kommt die Druckfeder 36 mit der Querplatte 30 in Kontakt und wird zwischen dieser und der Zunge 33. zusammengedrückt, während die Druckfeder 35 nicht mehr in Kontakt mit der Querplatte 29 steht, sondern entspannt ist. In jeder der beiden Endstellungen des Schlittens 27 und damit der Schalplatte 19 ist also eine der beiden Druckfedern 35 und 36 zusammengedrückt und damit vorgespannt, während die andere Druckfeder entspannt ist.Each carrier 3 consists of two parallel U-profiles which are arranged at a distance from one another and are connected to one another in the central region by means of transverse plates 29 and 30. The carriage 27 has a plate 31 resting on the upper side of the carrier 3 and bridging the two U-profiles, on the underside of which two tongues 32 and 33 projecting between the U-profiles are attached. A rod 34 extends between these tongues 32 and 33, on which two compression springs 35 and 36 are seated, each of which is attached at one end to one of the tongues 32 and 33, respectively. With the other end, the compression spring 35 can come into contact with the cross plate 29 and the compression spring 36 can come into contact with the cross plate 30. In the illustrated position of the carriage 27, the compression spring 35 bears against the cross plate 29 and is compressed between the latter and the tongue 32, while the compression spring 36 is relaxed because it is not with the cross plate 30 is in contact, however, the carriage is returned to the other position in which the formwork plate 19 is disengaged from the working position, the compression spring 36 comes into contact with the cross plate 30 and is compressed between the latter and the tongue 33rd while the Compression spring 35 is no longer in contact with the cross plate 29, but is relaxed. In each of the two end positions of the slide 27 and thus the formwork plate 19, one of the two compression springs 35 and 36 is thus compressed and thus preloaded, while the other compression spring is relaxed.

Zum Verstellen des Schlittens 27 ist ein Handhebel 37 vorgesehen, der an einem unterhalb des Trägers 3 befindlichen Gelenk 38 schwenkbar gelagert ist, Auf der Oberseite der Platte 31 des Schlittens 27 sind mehrere seitlich überstehende Bleche 39 befestigt, beispielsweise angeschweißt, zwischen denen sich als Rasten dienende Zwischenraume 40 befinden, in die der Handhebel 37 von außen eingerückt werden kann, Zum Verstellen des Schlittens 27 wird der Handhebel 37 in der einen oder anderen Richtung verschwenkt und ggfs, von einem Zwischenraum 40 zum nächsten umgesetzt, falls der mit einer Rast erzielbare Verschiebeweg nicht ausreicht, Eine nicht dargestellte Fußbremse dient zum Anhalten des Schlittens, beispielsweise wenn der Handhebel 37 umgesetzt wird, und gibt den Schlitten für Bewegungen nur frei, wenn sie betätigt, d.h. also getreten wird.To adjust the slide 27, a hand lever 37 is provided, which is pivotably mounted on a joint 38 located below the carrier 3. On the top of the plate 31 of the slide 27, a plurality of laterally projecting sheets 39 are fastened, for example welded, between which there are catches Serving spaces 40 are in which the hand lever 37 can be inserted from the outside. To adjust the slide 27, the hand lever 37 is pivoted in one direction or the other and, if necessary, moved from one space 40 to the next, if the displacement path achievable with a rest not sufficient, a foot brake, not shown, is used to stop the slide, for example when the hand lever 37 is moved, and only releases the slide for movements when it is actuated, ie is kicked.

Der Bock 26 ist auf der Oberseite der Platte 31 des Schlittens 27 angebracht. Im Bereich des Bockes 26 sind am Schlitten 27 Rollen 41 gelagert, welche unter den Träger 3 bzw. seine beiden U-Profile greifen, so daß ein Abheben des Schlittens 27 vom Träger 3 verhindert wird.The bracket 26 is attached to the top of the plate 31 of the carriage 27. In the area of the bracket 26, rollers 41 are mounted on the carriage 27, which engage under the carrier 3 or its two U-profiles, so that lifting of the carriage 27 from the carrier 3 is prevented.

Die Längen der Stützen 22, der Streben 25 und der Diagonalstreben 28 werden nach der Montage nicht mehr verändert. Dementsprechend wird die Schalplatte 19 beim Verstellen der Schlitten 27 auf einem Kreisbogen um den Anlenkpunkt 23 bewegt, dessen Scheitelpunkt senkrecht über dem Anlenkpunkt 23 liegt. Beim Verstellen aus der in der Zeichnung dargestellten Betriebsposition wird die Schalplatte 19 zunächst angehoben und, nachdem sie über den Anlenkpunkt 23 hinweggegangen ist, wieder abgesenkt. Somit drückt das Gewicht der Schalplatte 19 in der Betriebsposition gegen den zu betonierenden Wandabschnitt und in der rückgestellten Position in Rückstellrichtung. Die in den Federn 35 und 36 gespeicherten Kräfte erleichtern die Verstellbewegungen der Schalplatte zu Beginn jedes Verstellvorganges, so daß für das Anheben der Schalplatte 19 bis in den Scheitelpunkt des Bewegungskreises keine übermäßig hohen Kräfte benötigt werden.The lengths of the supports 22, the struts 25 and the diagonal struts 28 are no longer changed after assembly. Accordingly, the formwork plate 19 is moved when adjusting the slide 27 on a circular arc around the articulation point 23, the apex of which is perpendicular to the articulation point 23. When adjusting from the operating position shown in the drawing, the formwork panel 19 is first raised and, after it has passed over the articulation point 23, lowered again. Thus, the weight of the formwork panel 19 in the operating position presses against the wall section to be concreted and in the reset position in the reset direction. The forces stored in the springs 35 and 36 facilitate the adjustment movements of the formwork plate at the beginning of each adjustment process, so that no excessively high forces are required for lifting the formwork plate 19 up to the apex of the movement circle.
