Verbindungselemente sind an den Enden der quaderförmigen Module der Turmelemente und des wenigstens einen Obergurts und an wenigstens drei Seiten der Adaptermodule vorgesehen. Die Verbindungselemente sind auf einfache Weise als mit Löchern versehene Laschen ausgebildet, wobei ein Teil der Verbindungselemente als Doppellasche ausgebildet und die Anordnung der Verbindungselemente an den Modulen so getroffen sein kann, dass im zusammengesetzten Zustand zweier Module eine Einzellasche des einen zwischen die beiden Laschen einer Doppellasche des anderen Moduls greift und ein gemeinsamer Schraubbolzen in die fluchtenden Löcher der eine Verbindungsanordnung darstellenden Laschen gesteckt ist.Connecting elements are provided at the ends of the cuboid modules of the tower elements and the at least one upper flange and on at least three sides of the adapter modules. The connecting elements are designed in a simple manner as tabs provided with holes, with some of the connecting elements being designed as double tabs and the arrangement of the connecting elements on the modules such that when two modules are assembled, a single tab of one is between the two tabs of a double tab of the other module engages and a common screw bolt is inserted into the aligned holes of the tabs constituting a connecting arrangement.

Die laschenförmigen Verbindungselemente sind an den Ecken der stirnseitigen Begrenzungsflächen der Module derart angebracht, dass die jeweils diagonal paarweise einander gegenüberliegenden Laschen einer Verbindung zwischen zwei Modulen sich zueinander parallelen Ebenen erstrecken und die Ebenen des einen Paares gegenüber den Ebenen des anderen Paares um 90° versetzt angeordnet sind. Auf diese Weise können auf die Module einwirkende Seitenkräfte besser aufgefangen werden.The tab-shaped connecting elements are attached to the corners of the front-side boundary surfaces of the modules in such a way that the tabs of a connection between two modules, diagonally opposite in pairs, extend planes parallel to one another and the planes of one pair are offset by 90 ° relative to the planes of the other pair are. In this way, the side forces acting on the modules can be better absorbed.

Die Module des zumindest einen Obergurtes können mit einer zusätzlichen Komponente versehen sein, wobei die Komponenten der Module sich in montiertem Zustand derselben zu einer in Längsrichtung des Obergurts verlaufenden begehbaren Fläche ergänzen, die mit einer Absturzsicherung versehen ist. Die für ein Turmelement vorgesehenen Module können ebenfalls mit einer zusätzlichen Komponente versehen sein, wobei diese Komponenten in montiertem Zustand des Turmelementes zu sich zu einem vertikalen Steiggang mit Rückenschutz und Ruheplattformen ergänzen.The modules of the at least one upper chord can be provided with an additional component, the components of the modules complementing each other in the assembled state of the same to form a walk-on area which runs in the longitudinal direction of the upper chord and is provided with a fall protection device. The Modules provided for a tower element can also be provided with an additional component, these components supplementing each other in the assembled state of the tower element to form a vertical access passage with back protection and resting platforms.

Das Errichten des Gerüstes gemäß der Erfindung kann in der Weise erfolgen, dass zunächst auf dem Boden der aus den quaderförmigen Modulen und den Adaptermodulen zusammengesetzte Obergurt montiert wird, der dann mittels wenigstens einer Hubeinrichtung um eine Wegstrecke angehoben wird, welche die Anordnung jeweils eines für die Turmelemente vorgesehenen Moduls in einer Position ermöglicht, in welcher es mit dem Obergurt durch Befestigung an dem jeweiligen dafür vorgesehenen Adaptermodul verbunden wird. Dies kann auf dem Boden unter Verwendung z.B. von kleinen Montagegerüsten geschehen, deren Höhe die Länge eines quaderförmigen Moduls nicht zu übersteigen braucht. Nach Anbringen des ersten quaderförmigen Moduls am Adaptermodul des Obergurtes wird letzteres in weiterer Folge mit den jeweils bereits montierten Modulen für die Turmelemente schrittweise um eine entsprechende Distanz angehoben, um so jeweils nacheinander weitere Module für die Turmelemente anzubringen und das Gerüst zu komplettieren und dann das Gerüst mit den Turmelementen auf entsprechend vorbereitete Fundamentelemente aufzusetzen und mit diesen zu verbinden.The erection of the scaffolding according to the invention can be done in such a way that the upper chord composed of the cuboid modules and the adapter modules is first mounted on the floor, which is then raised by means of at least one lifting device by a distance, which the arrangement in each case one for the Tower elements provided module allows in a position in which it is connected to the top belt by fastening to the respective adapter module provided. This can be done on the floor using, for example, small assembly scaffolding whose height does not need to exceed the length of a cuboid module. After the first cuboid module has been attached to the adapter module of the top chord, the latter is then connected to the modules that have already been installed for the tower elements gradually increased by a corresponding distance in order to attach further modules for the tower elements one after the other and to complete the scaffolding and then to place the scaffolding with the tower elements on appropriately prepared foundation elements and connect them to them.

Die Länge der quaderförmigen Module wird im Allgemeinen so bemessen sein, dass es ohne aufwendige Maßnahmen möglich ist, die Module für die Turmelemente jeweils bodennah zu montieren, sodass ein Betreten des Gerüstes während der Montage nicht unbedingt erforderlich ist. Im Allgemeinen wird ein kleines Arbeitsgerüst ausreichen, um das jeweils nächste Modul am zu komplettierenden Turmelement anzuhängen.The length of the cuboid modules will generally be dimensioned so that it is possible to assemble the modules for the tower elements close to the ground without complex measures, so that it is not absolutely necessary to step onto the scaffolding during assembly. In general, a small scaffold will be sufficient to attach the next module to the tower element to be completed.

Die Anzahl der Turmelemente wird von der Länge des Obergurtes und gegebenenfalls auch von der Tragfähigkeit des jeweils einzusetzenden wenigstens einen Hubelementes abhängen. Letzteres gilt auch für die maximale Höhe des zu errichtenden Gerüstes, wobei dessen Standfähigkeit im Bedarfsfall durch Abspannseile gesichert werden kann.The number of tower elements will depend on the length of the upper chord and possibly also on the load-bearing capacity of the at least one lifting element to be used. The latter also applies to the maximum height of the scaffolding to be erected, whereby its stability can be secured by guy ropes if necessary.

Die drei in Figur 1 dargestellten Gerüste weisen insoweit denselben Grundaufbau auf, als die jeweils mit einem Obergurt 12, zwei Turmelementen 14 und zwei Fundamentelementen 16 versehen sind. Auf letzteren sind die Turmelemente 14 aufgesetzt.The three in Figure 1 The frameworks shown have the same basic structure in that they are each provided with an upper chord 12, two tower elements 14 and two foundation elements 16. The tower elements 14 are placed on the latter.

Obergurt 12 und Turmelemente 14 sind im Wesentlichen aus quaderförmigen Modulen 18 zusammengesetzt, von denen eines in Figur 3 dargestellt ist. Jedes der Module ist als Stabwerk ausgebildet und mit vier parallelen in Längsrichtung verlaufenden Stäben 20 versehen, die am jeweiligen Ende des Quaders durch vier Querstäbe miteinander verbunden sind. Die Längsstäbe 20 weisen eine merklich größere Länge auf als die Querstäbe, sodass bei dem in den Zeichnungen dargestellten Ausführungsbeispiel an wenigstens zwei gegenüberliegenden Seiten 24, 26 des Moduls eine Diagonalstrebe 28 angebracht ist. In Figur 3 ist eine Anordnung dargestellt, bei welcher auf jeder der beiden Seiten Streben 28 vorgesehen sind, die jeweils von einem Ende des Moduls ausgehen und sich in einer das Modul hälftig unterteilenden Ebene treffen und dort am gegenüberliegenden Längsstab angebracht sind. Weiterhin ist eine weitere in dieser Ebene verlaufende Diagonalstrebe in der Strebe 30 vorgesehen. Die Anzahl und Anordnung dieser Streben hängt von den jeweiligen Gegebenheiten ab, insbesondere auch von der Länge der Module, die allgemein zum Beispiel etwa zwei Meter betragen kann.The top chord 12 and tower elements 14 are essentially composed of cuboid modules 18, one of which is shown in FIG Figure 3 is shown. Each of the modules is designed as a framework and provided with four parallel rods 20 running in the longitudinal direction, which are connected to one another at the respective end of the cuboid by four transverse rods. The longitudinal rods 20 have a significantly greater length than the transverse rods, so that in the exemplary embodiment shown in the drawings, a diagonal strut 28 is attached to at least two opposite sides 24, 26 of the module. In Figure 3 an arrangement is shown in which struts 28 are provided on each of the two sides, each extending from one end of the module and meeting in a plane dividing the module in half and being attached there to the opposite longitudinal rod. Furthermore, another diagonal strut running in this plane is provided in the strut 30. The number and arrangement of these struts depends on the particular circumstances, in particular also on the length of the modules, which can generally be about two meters, for example.

Die Verbindung zwischen Obergurt 12 und dem jeweiligen Turmelement 14 erfolgt unter Verwendung eines Adaptermoduls 32, welches aus Stäben 34 mit derselben Länge zusammengesetzt ist und somit die Form eines Würfels aufweist (Figur 4). Die Flächen des Würfels entsprechen bezüglich Dimensionen und Form den Stirnflächen 27 der quaderförmigen Module. Weil die quaderförmigen Module von Obergurt und Turmelementen zumindest bezüglich ihrer Querschnittsform und -größe übereinstimmen, können somit sowohl die an das jeweilige Adaptermoduls 32 angrenzenden Module 18 des Obergurtes 12 als auch die entsprechenden Module der Turmelemente 14 mit dem Adaptermodul verbunden werden, wie dies insbesondere aus Figur 2 ersichtlich ist. Das Adaptermodul 32 ist an zwei seiner einander gegenüberliegenden Flächen mit jeweils einem quaderförmigen Modul 18 verbunden. An einer weiteren, zu den beiden vorgenannten Flächen der senkrechten Fläche, die das Adaptermodul unterseitig begrenzt, ist jeweils das oberste quaderförmige Modul für das jeweilige Turmelementes 14 angebracht.The connection between the upper chord 12 and the respective tower element 14 is made using an adapter module 32, which is composed of rods 34 of the same length and thus has the shape of a cube ( Figure 4 ). The surfaces of the cube correspond in terms of dimensions and shape to the end faces 27 of the cuboid modules. Because at least the cuboid modules of the top chord and tower elements coincide with regard to their cross-sectional shape and size, both the modules 18 of the upper chord 12 adjoining the respective adapter module 32 and the corresponding modules of the tower elements 14 can thus be connected to the adapter module, as shown in particular from Figure 2 can be seen. The adapter module 32 is connected to a cuboid module 18 on two of its opposite surfaces. The uppermost cuboid module for the respective tower element 14 is attached to a further, to the two aforementioned surfaces of the vertical surface that delimits the adapter module on the underside.

Zur Herstellung der Verbindungen zwischen den einzelnen Modulen sind die quaderförmigen Module zumindest an ihren stirnseitigen Flächen mit Verbindungelementen versehen. Entsprechende Verbindungselemente befinden sich an wenigstens zwei aneinander gegenüberliegenden Flächen des Adaptermoduls 32 und wenigstens einer dazu senkrechten Fläche, die in montiertem Zustand des Gerüstes sich an der Unterseite des Adaptermoduls 32 befindet.To produce the connections between the individual modules, the cuboid modules are provided with connection elements at least on their end faces. Corresponding connecting elements are located on at least two mutually opposite surfaces of the adapter module 32 and at least one surface perpendicular thereto, which is located on the underside of the adapter module 32 in the assembled state of the frame.

Zur Befestigung der Module aneinander sind diese mit Befestigungsmitteln versehen, die als Laschen ausgebildet sind. An den quaderförmigen Modulen ist die Anordnung so getroffen, dass an jeder Stirnseite an den vier Ecken derselben abwechselnd Einzellaschen 36 und Doppellaschen 38 vorgesehen sind, wobei die Doppellaschen parallel zueinander und in einem Abstand voneinander angeordnet sind, derart, dass zwischen die beiden Laschen einer Doppellasche 38 eines Moduls einer Einzellasche eines benachbarten Moduls einsteckbar ist. Alle Laschen sind mit einem Loch versehen, wobei die Löcher aller Laschen in der Verbindungsposition miteinander fluchten, sodass sie einen Schraubenbolzen oder ein anderes geeignetes Verbindungsmittel aufnehmen können, um die Laschen beider benachbarten Module und damit die Module miteinander zu verbinden. Dabei ist die Anordnung so getroffen, dass die Laschen eines ersten Paares diagonal einander gegenüberliegender Verbindungen zu den Laschen der beiden anderen einander diagonal gegenüberliegenden Verbindungen um 90° um eine Achse verschwenkt angeordnet sind, welche parallel zu den Längsstäben 20 des jeweiligen Moduls verläuft, wie dies auch mit Draufsicht der Figur 5 erkennen lässt.To fasten the modules to one another, they are provided with fastening means that are designed as tabs. The arrangement of the cuboid modules is such that alternating single tabs 36 and double tabs 38 are provided on each end face at the four corners thereof, the double tabs being arranged parallel to one another and at a distance from one another, such that between the two tabs of a double tab 38 of a module of a single tab of an adjacent module can be inserted. All brackets are provided with a hole, the holes of all brackets being aligned with one another in the connection position so that they can receive a screw bolt or other suitable connecting means in order to connect the brackets of both adjacent modules and thus the modules to one another connect to. The arrangement is such that the tabs of a first pair of diagonally opposite connections to the tabs of the two other diagonally opposite connections are arranged pivoted by 90 ° about an axis which runs parallel to the longitudinal bars 20 of the respective module, like this also with top view of the Figure 5 reveals.

Die Adaptermodule 32 sind in entsprechender Weise mit derartigen Verbindungslaschen versehen mit dem Unterschied, dass diese sich nicht nur an zwei gegenüberliegenden Seiten 12 zur Verbindung mit den Modulen 18 des Obergurtes vorgesehen sind, sondern auch wenigstens an einer dritten Seite, die in montiertem Zustand der Teile nach unten, also dem zugehörigen Turmelement zugekehrt ist. Bei dem in der Zeichnung dargestellten Ausführungsbeispiel ist auch die Seite mit Verbindungslaschen versehen, welche im montierten Zustand nach oben gekehrt ist, also der unteren Seite gegenüberliegt. Dadurch kann die Handhabung des Adaptermoduls bei der Montage vereinfacht werden.The adapter modules 32 are provided in a corresponding manner with such connecting straps, with the difference that they are not only provided on two opposite sides 12 for connection to the modules 18 of the upper chord, but also at least on a third side, which is in the assembled state of the parts down, so facing the associated tower element. In the embodiment shown in the drawing, the side is also provided with connecting straps which, in the assembled state, is turned upwards, that is, opposite the lower side. This can simplify the handling of the adapter module during assembly.

Die beiden Turmelemente 14 sind auf jeweils einem Fundamentelement 41 (Figur 5) aufgesetzt, welches aus zwei Längsträgern, zum Beispiel Doppel-T-Trägern 42 und einigen diese Längsträger verbindenden Querträgern 44 besteht und auf dem das Gerüst aufnehmenden Boden angeordnet und gegebenenfalls verankert ist. Die Fundamentelemente 41 können in Abhängigkeit von der Beschaffenheit des Bodens, auf welchem sie aufgesetzt sind unterseitig mit Fortsätzen oder dergleichen versehen sein, die eine gegebenenfalls erforderliche Sicherung gegen Verschieben bewirken. Die in der Mitte befindlichen Querträger 44 sind ebenfalls mit Einzellaschen 36 und Doppellaschen 38 entsprechend der Anbringung der Laschen an dem quaderförmigen Modul derart versehen, dass das untere Ende des jeweils untersten Moduls des Turmelementes mit dem Fundamentelement 41 in der beschriebenen Weise verbunden werden kann. Insbesondere Figur 5 der Zeichnung lässt erkennen, wie die Laschen der Verbindungen gegeneinander versetzt angeordnet sind, derart, dass seitliche Kräfte besser aufgefangen werden können. Eine - gegebenenfalls zusätzliche - Sicherung jedes Fundamentelements kann gegebenenfalls zusätzlich durch an den beiden Enden desselben aufgelegte Gewichte 45, beispielsweise Betonelemente erfolgen, die oberseitig mit einer Öse 52 der gleichen versehen sind, damit sie mit einem Hubelement in die gewünschte Position gebracht bzw. aus dieser entfernt werden können.The two tower elements 14 are each on a foundation element 41 ( Figure 5 ), which consists of two longitudinal beams, for example double-T beams 42 and some cross beams 44 connecting these longitudinal beams and is arranged and optionally anchored on the floor receiving the scaffolding. The foundation elements 41 can, depending on the nature of the ground on which they are placed, be provided with extensions or the like on the underside, which provide a safeguard against displacement that may be required. The cross members 44 located in the middle are also provided with single straps 36 and double straps 38 corresponding to the attachment of the straps to the cuboid module in such a way that the lower end of the respective lowermost module of the tower element is connected to the foundation element 41 in the manner described can be. Especially Figure 5 The drawing shows how the tabs of the connections are offset from one another in such a way that lateral forces can be better absorbed. An - possibly additional - securing of each foundation element can also be done by means of weights 45, for example concrete elements, placed on both ends of the same, which are provided with an eyelet 52 of the same on the top so that they can be brought into the desired position with a lifting element or out of this can be removed.

Das in Figur 1c) dargestellte Gerüst ist entlang dem Obergurt mit einer Arbeitsplattform 46 versehen, der ein Geländer 48 zugeordnet ist. Die Module des Obergurts, sowie die Adaptermodule sind mit entsprechenden zusätzlichen Komponenten versehen, die sich im montierten Zustand der Module zu dieser Arbeitsplattform in dem oder den Geländer(n) ergänzen. Das rechte Turmelement des Gerüstes gemäß Figur 1c ist mit einem vertikalen Steiggang mit Rückenschutz und Ruheplattformen versehen. Die Module dieses Turmelementes sind mit entsprechenden Komponenten versehen sind, die sich zu dem Steiggang usw. ergänzen.This in Figure 1c ) The frame shown is provided along the top chord with a work platform 46 to which a railing 48 is assigned. The modules of the upper chord and the adapter modules are provided with corresponding additional components which, when the modules are installed, complement each other to form this work platform in the railing (s). The right tower element of the scaffolding according to Figure 1c is provided with a vertical climb with back protection and resting platforms. The modules of this tower element are provided with corresponding components that complement each other to the climbing gear, etc.

Das Gerüst gemäß Figur 1a ist aufgrund seiner größeren Höhe mit Abspannseilen 54 gesichert.The scaffolding according to Figure 1a is secured with guy ropes 54 due to its greater height.

Das Gerüst gemäß der Erfindung kann auch mehr als zwei Turmelemente aufweisen.The framework according to the invention can also have more than two tower elements.

Es besteht natürlich die Möglichkeit, zwei oder mehr Gerüste der vorbeschriebenen Art nebeneinander aufzubauen, beispielsweise zu beiden Seiten einer Straße oder dergleichen, um über die Straße geführte Hochspannungsleitungen abzuspannen.There is of course the possibility of building two or more scaffolding of the type described above next to one another, for example on both sides of a street or the like, in order to tension high-voltage lines running across the street.
