Description

Technisches GebietTechnical area

Die Erfindung betrifft ein Baugerüst, das durch Stangen, Längs- und Querbalken, Gerüstbelag, Geländer und Windverband gebildet ist.The invention relates to a scaffolding, which is formed by rods, longitudinal and transverse beams, scaffold deck, railing and wind band.

Bisheriger Stand der TechnikPrevious state of the art

Aus einer Mehrzahl von Patentschriften sind Modularsysteme bekannt, deren miteinander verbundene Elemente ein Gerüsttragwerk bilden. DE 820963 beschreibt ein Gerüst mit den Merkmalen des Oberbegriffs des Anspruchs 1. Weiterhin gibt es bekannte Gerüstsysteme, die aus komplexen Teilen - am häufigsten aus Rahmen bestehen. Die bekannten Modular- und Rahmengerüste werden aus Stahl oder verschiedenen Legierungen hergestellt. Die Praxis hat längst auf Holzgerüst verzichtet und dessen Entwicklung wurde eingestellt.From a plurality of patents, modular systems are known whose interconnected elements form a scaffold structure. DE 820963 describes a scaffold with the features of the preamble of claim 1. Furthermore, there are known scaffolding systems that consist of complex parts - most often made of frames. The known modular and frame scaffolds are made of steel or different alloys. The practice has long since renounced wooden scaffolding and its development has been discontinued.

Nachteilig an den gegenwärtig hergestellten und benutzten Modular- und Rahmengerüsten ist ihr relativ hoher Anschaffungspreis. Deren nötige Variabilität verlangt eine große Zahl von Elementen und Zusatzteilen, was den Preis weiter erhöht. Wenn diese Gerüste aus Stahl hergestellt sind, ist der Aufbau infolge deren Gewichts ziemlich anstrengend.A disadvantage of the currently produced and used modular and frameworks is their relatively high purchase price. Their necessary variability requires a large number of elements and additional parts, which further increases the price. If these frames are made of steel, the structure is quite tiring due to their weight.

Der Erfindung liegt daher die Aufgabe zu Grunde, ein Baugerüst zu entwerfen, das die Nachteile der bekannten Lösungen wesentlich beschränkt.The invention is therefore based on the object to design a scaffolding that substantially limits the disadvantages of the known solutions.
