Abstract
Description
Die Erfindung betrifft einen Gerüstmast mit mindestens zwei Profilstäben, die auf Ecken eines den Querschnitt des Gerüstmastes bildenden Dreiecks oder Vierecks angeordnet sind, wobei je zwei Profilstäbe mit je einem Verbindungsblech oder mit je zwei Verbindungsblechen verbunden sind, die je eine Seite des Dreiecks oder Vierecks bilden.The invention relates to a scaffold mast with at least two profile bars, those on corners of a cross section of the scaffolding mast Triangles or quadrilaterals are arranged, two profile bars each are connected to one connecting plate or two connecting plates, each of which forms one side of the triangle or quadrangle.
Ein solcher Gerätemast ist beispielsweise aus DE 88 16 101 U1 bekannt.Such a device mast is known for example from DE 88 16 101 U1.
Es ist weiterhin ein leichter Antennen-Abspannmast bekannt, der aus drei Profilstäben besteht, die miteinander so verbunden sind, daß sie im Querschnitt ein gleichseitiges Dreieck bilden. Die Profilstäbe sind untereinander gleich ausgebildet. Einer dieser Profilstäbe besteht aus einem Blech, an dessen einer Seite eine kreiszylindrische Verstärkung und an dessen anderer Seite ein seitlich offener Rohrabschnitt vorgesehen ist. Dabei nimmt der seitlich offene Rohrabschnitt des einen Profilstabes die zylindrische Verstärkung des benachbarten Profilstabes auf. Dieser bekannte Antennen-Abspannmast besteht somit aus standardisierten speziell gepreßten Profilen.There is also known a light antenna mast, which consists of three There are profile bars that are connected to each other so that they are in the Cross-section form an equilateral triangle. The profile bars are equally trained among themselves. One of these profile bars exists from a sheet, on one side a circular cylindrical reinforcement and on the other side a pipe section open on the side is provided. The pipe section that is open at the side takes one of the profile bars the cylindrical reinforcement of the neighboring Profile bar on. This well-known antenna mast thus consists of standardized specially pressed profiles.
Der Erfindung liegt die Aufgabe zugrunde, einen Gerüstmast der einleitend genannten Art zu schaffen, bei dem die Breite und/oder die Dicke der Verbindungsbleche unterschiedlich ausgebildet sein können bzw. kann und somit statisch individuell auslegbare Gerüstmasten realisierbar sind.The invention has for its object a scaffolding mast to create the type mentioned, in which the width and / or the thickness of the connecting plates may be different can or can and therefore statically individually designed scaffolding masts are realizable.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß an dem Innenbereich eines jeden Profilstabes je zwei Nuten vorgesehen sind und daß abgewinkelte Kanten des Verbindungsbleches in diese Nuten eingesteckt und an der Einsteckstelle befestigt sind.This object is achieved in that the Inside of each profile bar two grooves are provided and that angled edges of the connecting plate inserted into these grooves and are attached to the insertion point.
Auf diese Weise gelangt man zu einem Gerüstmast, der wegen der unterschiedlichen Breite und/oder Dicke der Bleche entsprechend unterschiedlich realisiert werden kann. Es ist somit möglich, einen Gerüstmast zu schaffen, bei dem speziell für die Ecken und andere wichtige Verbindungslinien Profilstäbe zu pressen sind, die auch mit zusätzlichen Funktionsmöglichkeiten ausgestattet werden können, zum Beispiel mit Führungen für Rollen, Aufnahmeteilen für andere mechanische Komponenten und dgl.. Außerdem besteht die Möglichkeit, Bleche ggf. auch unterschiedlicher Dicke aufnehmen zu können, die über die um ggf. 90° zur Zugrichtung des Bleches verdrehte Aufnahmenuten nur noch mit vergleichsweise geringem Aufwand zu verschweißen sind. Über die unterschiedliche Breite und/oder Dicke der Bleche sind somit statisch individuell auslegbare Träger oder Stützen realisierbar.In this way you get to a scaffolding mast, because of the different width and / or thickness of the sheets accordingly can be realized differently. It is therefore possible to have one To create scaffolding mast, especially for the corners and others important connecting lines to press profile bars that are also with additional functions can be equipped, for example with guides for rollers, receiving parts for others mechanical components and the like. There is also the possibility of To be able to accommodate sheets of different thicknesses if necessary, which is rotated by possibly 90 ° to the sheet's direction of pull Recording grooves only with comparatively little effort are welded. About the different width and / or thickness the sheets are thus statically individually designed supports or Supports can be realized.
Bei weiten Abständen zwischen zwei Profilstäben, die durch ein statisch belastetes Blech überbrückt werden müssen, besteht üblicherweise die Gefahr der Blechbeulung. Dem wird bei großen Spannweiten zwischen den Profilstäben durch entsprechende Formgebung des Bleches entgegengewirkt, indem beispielsweise das Blech mit Kantungen oder Sicken versehen oder als quer zur Trägerachse verlaufendes Wellenprofil ausgelegt wird. Bei weiten Abständen zwischen den Profilstäben und nur geringer statischer Belastung des Tragprofiles können in den Blechen auch Ausstanzungen zur Gewichtsreduzierung eingebracht sein.In the case of wide distances between two profile bars, which are separated by a static loaded sheet must usually be bridged the danger of buckling. That will be the case with large spans between the profile bars by appropriate shaping of the Sheet metal counteracted, for example by the sheet with folds or beads or as transverse to the support axis Wave profile is designed. With wide distances between the profile bars and only a small static load on the support profile can also punch holes in the sheets to reduce weight be introduced.
Bei den bekannten Stützen und Trägern aus gepreßten Profilstäben ist die Form der Profilstäbe unveränderbar festgelegt, so daß eine Verkettung speziell gepreßter Profile zwangsweise eine entsprechend konstruierte Form ergibt. Abweichungen von dieser vorher konstruktiv festgelegten Form und damit Abweichungen von den statischen Gegebenheiten sind bei dem bekannten Gerüstmast nicht möglich.In the known supports and beams made of pressed profile bars the shape of the profile bars is fixed so that a Linking of specially pressed profiles inevitably leads to a corresponding constructed form results. Deviations from this before constructively determined form and thus deviations from the static There are no circumstances with the known scaffolding mast possible.
In Ausgestaltung der Erfindung können als Profilstäbe Aluminium-Strangpreßprofile vorgesehen sein. Es ist auch möglich, Profilstäbe aus Stahl in Form von Hohl- oder Walzprofilen oder dgl. vorzusehen. Des weiteren können die in die Nuten eingesetzten Verbindungsbleche mit den Profilstäben verschweißt sein. Die Profilstäbe können gleich oder ungleich ausgebildet sein.In an embodiment of the invention, extruded aluminum profiles can be used as profile bars be provided. It is also possible to use profile bars made of steel in the form of hollow or rolled profiles or the like. Furthermore, the connecting plates used in the grooves be welded to the profile bars. The profile bars can be the same or different.
Des weiteren empfiehlt es sich, daß die Profilstäbe untereinander gleich oder ungleich ausgebildet sind.Furthermore, it is recommended that the profile bars be one below the other are the same or different.
Zweckmäßig ist an wenigstens einem Profilstab ein längs des Profilstabes in Längsrichtung des Gerüstmastes selbstfahrbarer Schlitten angeordnet.It is expedient to have at least one profile bar along the profile bar carriage self-propelled in the longitudinal direction of the scaffolding mast arranged.
Es empfiehlt sich, die Verbindungsbleche entsprechend ihrer statischen Belastungen auszubilden. It is recommended to use the connecting plates according to their static Train loads.
