Abstract

The device has a cantilever arm attached to the edge of the platform and welded to the stub mast. The arm has two relatively mutually stiffened, vertically separate cantilever arm plates, preferably of steel with openings for the stub mast. The edges of the cantilever arm plates are fixed to the outer surface of the stub mast, especially by welding.

Description

Die Erfindung bezieht sich auf eine Vorrichtung zur verwindungssteifen Befesti­ gung eines Antennen-Trägerrohrs an der Plattform eines Antennenmastes, mit einem am Rand der Plattform befestigten, mit dem Trägerrohr verschweißten Kragarm.The invention relates to a device for torsionally rigid fastening supply of an antenna support tube on the platform of an antenna mast, with one attached to the edge of the platform, welded to the support tube Cantilever.

Derartige Vorrichtungen, bei denen die Antenne unter Verwendung eines Träger­ rohrs gehaltert ist und nicht direkt am Rand der Plattform unmittelbar befestigt wird, haben einmal den Zweck, die häufig nicht biegesteifen Stabantennen durch Verstrebung an den Trägerrohren zu versteifen und zum anderen dienen solche Trägerrohre auch dazu, Antennenschüsseln in größeren Abständen zur Plattform, also beispielsweise einige Meter oberhalb der Plattform positionieren zu können. Dabei ergibt sich die Schwierigkeit, dass an der Verschweißung des Antennen- Trägerrohrs mit dem in der Praxis meist als Rechteckrohr ausgebildeten Kragarm ein Steifigkeitssprung auftritt, so dass angesichts der hohen Winddrucke, die auf solchen Bauwerken lasten und der daraus resultieren den hohen und ständig wech­ selnden Kräfte eins erhebliche Gefahr besteht, dass die Schweißnähte auf Dauer nicht halten und im Extremfall die Antennen abstürzen können.Such devices, in which the antenna using a carrier is supported and not directly attached to the edge of the platform once have the purpose to pass through the often non-rigid rod antennas To brace struts on the support tubes and on the other hand serve such Carrier tubes also to antenna dishes at greater distances from the platform, So for example to be able to position a few meters above the platform. The difficulty arises here that the welding of the antenna Carrier tube with the cantilever arm, which is usually designed as a rectangular tube in practice a stiffness jump occurs, so given the high wind pressures that are on such structures are burdensome and the resulting high and constantly changing selseling forces there is a significant risk that the welds in the long run cannot hold and in extreme cases the antennas can fall.

Der Erfindung liegt daher die Aufgabe zugrunde, eine Vorrichtung der eingangs genannten Art dahingehend auszugestalten, dass eine sichere dauerhafte, auch hohen Belastungen standhaltende Befestigung der Antennen-Trägerrohre an der Plattform eines Antennenmastes möglich ist.The invention is therefore based on the object of a device at the outset mentioned type in such a way that a safe permanent, too the antenna carrier tubes can withstand high loads Platform of an antenna mast is possible.

Zur Lösung dieser Aufgabe ist erfindungsgemäß vorgesehen, dass der Kragarm zwei gegeneinander versteifte vertikal beabstandete Kragarm-Platten, vorzugs­ weise aus Stahl, umfasst, die das Trägerrohr aufnehmende Ausnehmungen auf­ weisen, deren Randkanten mit der Außenfläche des Trägerrohrs fest verbunden, insbesondere verschweißt sind. Durch diese Aufnahme des Trägerrohrs in den beiden miteinander fluchtenden Ausnehmungen der Kragarm-Platten ist der Stei­ figkeitssprung, wie er durch das stumpfe Anschweißen eines Rechteckrohrs ent­ steht, vollständig vermieden. Obgleich es prinzipiell möglich wäre, wird man dabei allerdings in der Praxis meist nicht eine Lösung wählen, bei der der Kragarm als Rechteckrohr mit einer solch großen Breite ausgebildet ist, dass das Trägerrohr in eine durchgehende Bohrung eingesteckt werden kann.To achieve this object, the cantilever is provided according to the invention two mutually stiffened vertically spaced cantilever plates, preferably example made of steel, comprises the recesses receiving the carrier tube have, whose edge edges are firmly connected to the outer surface of the support tube, in particular are welded. Through this inclusion of the support tube in the the two aligned recesses of the cantilever plates is the Stei leap in ability, such as the butt welding of a rectangular tube is completely avoided. Although it would be possible in principle, you will  in practice, however, usually do not choose a solution in which the cantilever is used as Rectangular tube is formed with such a large width that the carrier tube in a through hole can be inserted.

Bevorzugt hat sich eine Konstruktion als geeignet erwiesen, bei der die Kragarm- Platten durch eine mittige Längs- und eine gleichzeitig zur Befestigung an der Plattform dienende stirnseitige Querversteifungsplatte gegeneinander verstrebt sind, wobei die Längsversteifungsplatte längs ihrer vier Kanten mit den anliegen­ den Bauteilen verschweißt sein soll. Bei dieser Konstruktion hat es sich darüber hinaus als zweckmäßig erwiesen, die Längsversteifungsplatte mit abgeschrägten Ecken zu versehen, was das Zusammenfügen der Bauteile und die unabhängige Setzung der Schweißnähte erleichtert.A construction in which the cantilever Panels by a central longitudinal and one at the same time for attachment to the Frontal cross-bracing plate serving as a strut braced against each other are, the longitudinal stiffening plate lying along its four edges with the the components should be welded. With this construction, it was about also proven to be useful, the longitudinal stiffening plate with beveled To provide corners, which is the assembly of the components and the independent Settling of the weld seams made easier.
