Description

Die Erfindung bezieht sich auf ein Montagegerüst für Schalungen für Rundbauten aus Beton od. dgl. mit einem horizontal ausgerichteten annähernd ringförmigen polygonalen Rahmen für ein Arbeitspodium mit einem Obergurt und einem Untergurt, die mittels Fachwerkstreben verbunden sind, der auf vorzugsweise drei säulenartigen Trägern höhenversetzbar lagert.The invention relates to an assembly scaffold for formwork for round buildings made of concrete or the like. With a horizontally oriented approximately ring-shaped polygonal frame for a work platform with an upper chord and a lower chord, which are connected by means of truss struts, which are supported on three pillar-like supports that can be displaced in height.

Es ist eine Vorrichtung zur Errichtung vorzugsweise umfanggeschlossener-Bauten, wie Silos, Schwimmbecken, Faultürmen od. dgl. aus gießfähigen Werkstoffen, beispielsweise Beton, bekannt, bei der eine höhenverstellbare Arbeitsplattform vorgesehen ist. Diese Arbeitsplattform ist auf drei-verlängerbaren Rohren gelagert, wobei ein ringförmiger Gitterträger montiert ist und an diesem ringförmigen Gitterträger sind strahlenförmige nach außen oder nach innen ragende Träger montiert, an denen die äußere und innere Schalhaut aufgehängt ist. Die Arbeitsplattform wird im Laufe des Baufortschrittes zusammen mit den daran hängenden Schalhäuten nach dem Erhärten des vergossenen Betons hochgezogen.A device for the construction of preferably closed buildings, such as silos, swimming pools, digestion towers or the like, made of pourable materials, for example concrete, is known, in which a height-adjustable working platform is provided. This work platform is mounted on three extendable tubes, an annular lattice girder being mounted, and on this annular lattice girder are mounted radiating outwardly or inwardly projecting girders on which the outer and inner formlining is suspended. As the construction progresses, the work platform, along with the formwork skins attached to it, is hoisted after the poured concrete has hardened.

Ein Nachteil der bekannten Arbeitsplattform ist darin zu sehen, daß für jeden Arbeitsdurchmesser eine eigene Arbeitsplattform zur Verfügung stehen muß.A disadvantage of the known work platform is the fact that a separate work platform must be available for each working diameter.

Aufgabe der Erfindung ist es, ein Montagegerüst der genannten Art zu schaffen, bei dem die Arbeitsplattform verschiedenen Gebäudedurchmessern angepaßt werden kann.The object of the invention is to provide an assembly frame of the type mentioned, in which the work platform can be adapted to different building diameters.

Dies wird erfindungsgemäß dadurch erreicht, daß der polygonale Rahmen an den Eckpunkten winkelverstellbar ist, und daß vorzugsweise jeder Rahmenabschnitt des polygonalen Rahmens zwischen zwei Eckpunkten ein separater Teil ist, der mit den angrenzenden Rahmenabschnitten lösbar verbunden, vorzugsweise verschraubt ist.This is achieved according to the invention in that the polygonal frame is angularly adjustable at the corner points, and that preferably each frame section of the polygonal frame between two corner points is a separate part which is detachably connected, preferably screwed, to the adjacent frame sections.

Vorteilhaft ist vorgesehen, daß die Ober- und Untergurtabschnitte der Rahmenabschnitte an den Verbindungsstellen gabelartig mit zwei Verbindungsstegen versehen sind, die in Montagelage im Wechsel a, b, a, b, aneinander anliegen.It is advantageously provided that the upper and lower flange sections of the frame sections are provided in a fork-like manner at the connection points with two connecting webs which, in the mounting position, alternately abut a, b, a, b.

Dadurch können an jedem Eckpunkt die Rahmenabschnitte getrennt werden und durch Einsetzen eines weiteren Rahmenabschnittes bzw. durch Einsetzen mehrerer Rahmenabschnitte kann der Durchmesser des Rahmens beliebig erweitert werden, wie er durch Herausnehmen von Rahmenabschnitten verringert werden kann. Durch Verstellen der Winkel an den restlichen Eckpunkten kann der polygonartige Rahmen dem kontinuierlichen Kreisverlauf angepaßt werden.As a result, the frame sections can be separated at each corner point, and by inserting a further frame section or by inserting several frame sections, the diameter of the frame can be expanded as desired, as can be reduced by removing frame sections. By adjusting the angles at the remaining corner points, the polygonal frame can be adapted to the continuous circle.

Ein weiterer Nachteil der bekannten Montagegerüste ist, daß die als Tragsäulen dienenden verlängerbaren Rohre innerhalb des Ringes der Arbeitsplattform angeordnet sind und das Versetzen der Arbeitsplattform bzw. das Lösen und ihr Befestigen an den Führungsrohren eine zeitaufwendige und gefährliche Arbeit ist, da dies nur unterhalb des Arbeitspodiums erfolgen kann.Another disadvantage of the known assembly scaffolds is that the extendable tubes serving as support columns are arranged within the ring of the work platform and the relocation of the work platform or the loosening and fastening to the guide tubes is a time-consuming and dangerous work, since this is only below the work platform can be done.

Es ist eine weitere Aufgabe der Erfindung, ein Montagegerüst zu schaffen, das diesen Nachteil nicht aufweist.It is a further object of the invention to provide an assembly frame which does not have this disadvantage.

Dies wird erfindungsgemäß dadurch erreicht, daß die Rahmenabschnitte mit ihrer Außenseite an den Trägern anliegen und mit diesen verbunden sind.This is achieved in that the Frame sections rest with their outside on the carriers and are connected to them.

Vorteilhaft ist vorgesehen, daß die zwei Verbindungsstege an einem Ende der Ober- bzw. Untergurtabschnitte im Winkel zur Längsachse des Obergurt- bzw. Untergurtabschnittes liegen. Dies macht es möglich, bei der Herstellung der Rahmenabschnitte mit tragbaren Toleranzen zu arbeiten.It is advantageously provided that the two connecting webs lie at one end of the upper and lower chord sections at an angle to the longitudinal axis of the upper chord and lower chord sections. This makes it possible to work with portable tolerances in the manufacture of the frame sections.

Ein Ausführungsbeispiel der Erfindung sieht vor, daß die Verbindungsstege mit Löchern für Verbindungsschrauben versehen sind, die zumindestens zum Teil auf einem Kreisbogen liegen. Teilweise sind diese Löcher Langlöcher. Vorteilhaft befindet sich jeweils ein Loch neben dem Zirkelpunkt des Kreisbogens.An embodiment of the invention provides that the connecting webs are provided with holes for connecting screws, which are at least partially on an arc. Some of these holes are elongated holes. A hole is advantageously located next to the circular point of the circular arc.

Ein weiteres Ausführungsbeispiel sieht vor, daß die Verbindungsstege am anderen Ende der Ober- bzw. Untergurtabschnitte in einen inneren und einen äußeren Stegteil, die sich an den beiden Seiten des Ober- bzw. Untergurtabschnittes-befinden, geteilt sind.A further embodiment provides that the connecting webs at the other end of the upper or lower chord into an inner and an outer web portion, located at both sides of the upper or Untergurtabschnittes - are, are divided.

Nachstehend wird ein Ausführungsbeispiel der Erfindung anhand der Figuren der beiliegenden Zeichnungen eingehend beschrieben.An exemplary embodiment of the invention is described in detail below with reference to the figures in the accompanying drawings.

Die Fig. 1 zeigt schematisch einen Vertikalschnitt durch ein erfindungsgemäßes Montagegerüst und die dazugehörige Schalung, die Fig. 2 zeigt eine schematisch gehaltene Draufsicht, die Fig. 3 zeigt schaubildlich eine Seitenansicht auf einen Abschnitt des erfindungsgemäßen Arbeitspodiums, die Fig. 4 zeigt eine Seitenansicht auf einen Rahmenabschnitt, die Fig. 5 zeigt eine Draufsicht auf einen Rahmenabschnitt, die Fig. 6 zeigt die Details A, B der Fig. 4 und zwar bei aneinanderliegenden Enden der Rahmenabschnitte, die Fig. 7 zeigt einen Schnitt entlang der Linie C-C der Fig. 6, die Fig. 8 zeigt die -Verbindung von Rahmen und Träger im Horizontalschnitt, die Fig. 9 zeigt schematisch das Ineinandergreifen der Abschnitte des Ober-und des Untergurtes, die Fig. 10 zeigt eire Draufsicht auf ein weiteres Ausführungsbeispiel eines Rahmenabschnittes, und die Fig. 11 zeigt eine Seitenansicht eines derartigen Rahmenabschnittes.1 schematically shows a vertical section through an assembly scaffold according to the invention and the associated formwork, FIG. 2 shows a schematically held top view, FIG. 3 shows a side view of a section of the working platform according to the invention, and FIG. 4 shows a side view a frame section, FIG. 5 shows a plan view of a frame section, FIG. 6 shows the details A, B of FIG. 4, namely when the ends of the frame abut one another FIG. 7 shows a section along the line CC of FIG. 6, FIG. 8 shows the connection of frame and carrier in horizontal section, FIG. 9 shows schematically the interlocking of the sections of the upper and lower chord, FIG. 10 shows a top view of a further exemplary embodiment of a frame section, and FIG. 11 shows a side view of such a frame section.

In Fig. 1 ist die in Herstellung befindliche Mauer mit 1 bezeichnet. Unmittelbar an der Mauer 1 liegt innen und außen die Schalhaut 2 an, die beispielsweise aus Stahl, Leichtmetall oder auch von Holz oder Kunststoff gebildet wird.In Fig. 1, the wall under construction is designated 1. Immediately against the wall 1, the formlining 2 lies inside and outside, which is formed, for example, from steel, light metal or also from wood or plastic.

Die Stahlprofilträger 3 des Schalungsgerüstes werden von äußeren polygonalen Ringen 4 gehalten bzw. sind mit diesen verschraubt.The steel profile beams 3 of the formwork scaffold are held by outer polygonal rings 4 or are screwed to them.

Wie aus der Fig. 2 ersichtlich, besteht jeder äußere oder innere Ring 4 aus Ringabschnitten 8, die an den Ekken 9 gelenkig miteinander verbunden sind.As can be seen from FIG. 2, each outer or inner ring 4 consists of ring sections 8 which are articulated to one another at the corners 9.

Aus Stabilitätsgründen wird jeder Ringabschnitt 8 vorzugsweise von einem Doppel-T-Träger gebildet. Es könnte jedoch auch ein Vierkantrohr zum Einsatz kommen, jedoch bietet der Doppel-T-Träger Vorteile im Hinblick auf ein schnelleres Fixieren, nachdem der Ring 4 einem neuen Durchmesser angepaßt wurde.For reasons of stability, each ring section 8 is preferably formed by a double T-beam. However, a square tube could also be used, but the double-T support offers advantages in terms of faster fixing after the ring 4 has been adapted to a new diameter.

An den Eckpunkten 9 kann die Gelenkverbindung entweder durch eine Achse oder durch Verbiegen des unteren Parallelsteges des Doppel-T-Trägers erfolgen.At the corner points 9, the articulated connection can be made either by an axis or by bending the lower parallel web of the double-T beam.

Die Innenschalung ist im Prinzip gleich aufgebaut wie die Außenschalung. Auf die Schalhaut 2 folgen die stehenden Stahlprofile 3, die von polygonen Ringen 4 gehalten werden.The inner formwork is basically the same as the outer formwork. The formwork skin 2 is followed by the standing steel profiles 3, which are held by polygonal rings 4.

Die Polygonringe 4, die vorzugsweise wie bei der Au- ßenschalung höhenverstellbar sind, haben bei der Innenschalung auch den entstehenden Ringdruck aufzunehmen, so daß sie in entsprechender Anzahl und Stärke vorgesehen sein müssen.The polygon 4 rings, which are preferably such as .beta. at the Au enschalung are adjustable in height have to include also the resulting annular pressure at the inner formwork, so that they must be provided in appropriate number and strength.

Im Inneren der Ringe 4 der Innenschalung sind die drei säulenartigen Träger 5 für die Arbeitsplattform 6 vorgesehen, die den polygonalen kreisringförmigen Rahmen 16 tragen. Dieser ist ein Fachwerk, bestehend aus einem Obergurt 17, einem Untergurt 18 und vertikalen und schrägen Streben 19, 20.Inside the rings 4 of the inner formwork, the three columnar supports 5 are provided for the work platform 6, which support the polygonal annular frame 16. This is a framework consisting of an upper flange 17, a lower flange 18 and vertical and oblique struts 19, 20.

Der Rahmen 16 wird dabei von separaten Rahmenabschnitten 16' gebildet. Jeder Rahmenabschnitt 16' weist neben einer statisch tragenden vertikalen Strebe 19 eine Hilfsstrebe 21 auf. Im Ausführungsbeispiel werden die Obergurtabschnitte 17' und die Untergurtabschnitte 18' von Vierkantrohren gebildet, ebenso wie die Vertikalverstrebungen 19 und die schrägen Verstrebungen 20. Es könnte jedoch auch ein anderes Profil, beispielsweise ein Doppel-T-Profil, das die notwendige Knicksteifigkeit aufweist, verwendet werden.The frame 16 is formed by separate frame sections 16 '. In addition to a statically supporting vertical strut 19, each frame section 16 ′ has an auxiliary strut 21. In the exemplary embodiment, the upper chord sections 17 'and the lower chord sections 18' are formed by square tubes, as are the vertical struts 19 and the oblique struts 20. However, a different profile, for example a double-T profile, which has the necessary buckling rigidity, could also be used will.

Der Rahmen 16 wird von miteinander verschraubten Rahmenabschnitten 16' gebildet. Jeder Obergurtabschnitt 17' und jeder Untergurtabschnitt 18' ist an seinen beiden Enden mit Verbindungsstegen 22, 23 versehen, die, wie aus der Fig. 9 ersichtlich, im Wechsel aneinandergreifen, sodaß jeweils ein Verbindungssteg 22 an einem Verbindungssteg 23 in der gleichen Folge anliegt.The frame 16 is formed by screwed together frame sections 16 '. Each upper chord section 17 'and each lower chord section 18' is provided at its two ends with connecting webs 22, 23 which, as can be seen in FIG. 9, engage in alternation, so that in each case one connecting web 22 abuts a connecting web 23 in the same sequence.

Die einzelnen Rahmensegmente 16' sind an den Verbindungsstegen 22, 23 miteinander verschraubt.The individual frame segments 16 'are screwed together at the connecting webs 22, 23.

Wie aus der Fig. 5 ersichtlich, sind die Verbindungsstege 22 im Winkel zur Längsachse des Ober- oder Untergurtabschnittes 17', 18' angeordnet und die Verbindungsstege 23 sind geteilt und es befindet sich je ein Teil auf jeder Seite des Ober- bzw. Untergurtabschnittes 17, 18.As can be seen from FIG. 5, the connecting webs 22 are arranged at an angle to the longitudinal axis of the upper or lower belt section 17 ', 18' and the connecting webs 23 are divided and there is a part on each side of the upper and lower chord sections 17, 18.

Jeder Verbindungssteg 22, 23 ist mit Löchern 24, 25 versehen, durch die die Verbindungsschrauben ragen, wobei ein Teil der Löcher Langlöcher 25 sind und diese sich auf einem Kreisbogen befinden, in dessen Zirkelpunkt ebenfalls ein Befestigungsloch 24 ist.Each connecting web 22, 23 is provided with holes 24, 25 through which the connecting screws protrude, some of the holes being elongated holes 25 and these being on an arc of a circle, in the circle point of which there is also a fastening hole 24.

Es ist leicht ersichtlich, daß durch Lösen der Verbindungsschrauben zwischen drei Rahmensegmenten 16' eins oder mehrere Rahmensegmente 16' aus dem Rahmen 16 herausgenommen werden können, worauf durch anschließendes Winkelverstellen an den Eckpunkten des polygonalen Ringes der Rahmen 16 auf einen kleineren Durchmesser eingestellt werden kann.It is easy to see that one or more frame segments 16 'can be removed from the frame 16 by loosening the connecting screws between three frame segments 16', whereupon the frame 16 can be adjusted to a smaller diameter by subsequent angular adjustment at the corner points of the polygonal ring.

Ebenso ist es möglich, den Rahmen 16 an einer Verbindungsstelle zwischen zwei Rahmenabschnitten 16' zu öffnen und neue Rahmenabschnitte 16' einzusetzen, um den Rahmen zu vergrößern.It is also possible to open the frame 16 at a connection point between two frame sections 16 'and to insert new frame sections 16' in order to enlarge the frame.

Wie insbesondere aus den Fig. 2 und 8 ersichtlich, liegen die säulenartigen Träger 5, die Doppel-T-Träger sind, außen an einem Rahmenabschnitt 16' des Rahmens 16 an. Dieser Rahmenabschnitt 16' hat an seinem Obergurtabschnitt 17' Haltemittel 26, die einen Steg 5' des Doppel-T-Trägers 5 umfassen und über die der Obergurtabschnitt 17' mit dem Steg 5' verbunden, beispielsweise mit diesem verschraubt ist. Der zweite Steg 5" des Doppel-T-Profiles des Trägers 5 ist in ähnlicher oder gleicher Weise mit den Ringen 4 des Schalungsgerüstes verbunden. Auch hier kann die Verbindung beispielsweise durch Verschrauben erfolgen.As can be seen in particular from FIGS. 2 and 8, the columnar supports 5, which are double-T supports, bear against the outside of a frame section 16 ′ of the frame 16. This frame section 16 'has on its upper chord section 17' holding means 26 which comprise a web 5 'of the double-T beam 5 and via which the upper chord section 17' is connected to the web 5 ', for example screwed to it. The second web 5 "of the double-T profile of the beam 5 is connected in a similar or identical manner to the rings 4 of the formwork framework. Here too, the connection can be made, for example, by screwing.

Dadurch, daß die Träger 5 seitlich sowohl am Rahmen 16 als auch an den Ringen 4 anliegen, bilden das Schalungsgerüst und das Arbeitsgerüst eine Einheit. Es wird das Arbeitsgerüst im Schalungsgerüst vertikal geführt. Mit dieser Anordnung wird auch erreicht, daß die Befestigung des Arbeitspodiums nicht unterhalb des Arbeitspodiums vorgenommen werden muß. Des weiteren können die Träger 5 direkt an der Betonwand gegen Ausknicken gesichert werden, was die ansonsten notwendigen gefährlichen Arbeiten unterhalb des Arbeitspodiums überflüssig macht.Characterized in that the supports 5 lie laterally on both the frame 16 and the rings 4, the formwork scaffold and the work scaffold form a unit. The work scaffold is guided vertically in the formwork scaffold. With the This arrangement also ensures that the mounting of the work platform does not have to be made below the work platform. Furthermore, the beams 5 can be secured against buckling directly on the concrete wall, which makes the otherwise necessary dangerous work below the work platform unnecessary.

Um die statische Belastbarkeit des Rahmens 26 zu erhöhen kann (wie in den Fig. 10 und 11 gezeigt) jeder Rahmenabschnitt 16' als dreidimensionales Fachwerk ausgeführt sein.In order to increase the static load-bearing capacity of the frame 26 (as shown in FIGS. 10 and 11), each frame section 16 'can be designed as a three-dimensional framework.

Vorteilhaft sind die Rahmenabschnitte 16' in Draufsicht trapezförmig.The frame sections 16 'are advantageously trapezoidal in plan view.
