Abstract

The pole (1) has a base plate (3) for mounting on a subsurface at a lower end of the pole. The base plate includes a ring-shaped chamber that is upwardly aligned to the pole and made up of steel. The chamber includes a concave contour in a corner region of the base plate that includes a central ring-shaped opening i.e. elongated hole, in the corner region of the base plate. A longitudinal axis of an elongated hole is approximately diagonal to adjacent edges of the base plate, where the thickness of the base plate is of 10 millimeters.

Description

Die Erfindung betrifft einen Mast, insbesondere einen Beleuchtungs-, Antennen-oder Leitungsmast, der an seinem unteren Ende eine Fußplatte zur Verankerung auf einem Untergrund aufweist.The invention relates to a mast, in particular a lighting, antenna or pylon, which has at its lower end a foot plate for anchoring to a substrate.

Derartige Masten besitzen an ihrem oberen Ende eine Beleuchtungseinrichtung oder einen Träger, zum Beispiel für Stromleitungen. Die auf den Mast einwirkenden Windlasten verursachen ein Biegemoment und gegebenenfalls ein Torsionsmoment, diese Momente müssen über die Fußplatte in den Untergrund abgetragen werden. Die Befestigung der Fußplatte auf dem Untergrund erfolgt herkömmlicherweise über Schrauben, die zum Beispiel in ein Betonfundament geschraubt sind. Das Biegemoment ruft in der Fußplatte Zug- und Druckkräfte hervor, sodass die Fußplatte vergleichsweise massiv dimensioniert werden muss, um den auftretenden Windlasten zu widerstehen. In der Praxis wurden die Fußplatten üblicher Lichtmasten zum Beispiel mit einer Dicke von 20 mm hergestellt, sodass der Materialverbrauch vergleichsweise hoch ist.Such masts have at their upper end a lighting device or a carrier, for example for power lines. The wind loads acting on the mast cause a bending moment and possibly a torsional moment, these moments must be removed via the footplate into the ground. The attachment of the base plate on the ground is conventionally carried out by screws, which are screwed, for example, in a concrete foundation. The bending moment causes tensile and compressive forces in the footplate, so that the footplate has to be comparatively massively dimensioned in order to withstand the occurring wind loads. In practice, the foot plates of conventional light poles were made, for example, with a thickness of 20 mm, so that the material consumption is comparatively high.

Der Erfindung liegt daher die Aufgabe zugrunde, einen Mast anzugeben, bei dem der Materialverbrauch verringert ist.The invention is therefore based on the object to provide a mast, in which the material consumption is reduced.

Zur Lösung dieser Aufgabe ist bei einem Mast der eingangs genannten Art erfindungsgemäß vorgesehen, dass die Fußplatte eine aufwärts zum Mast gerichtete, im Wesentlichen kreisförmige Wölbung aufweist.To solve this problem, it is provided according to the invention in a mast of the type mentioned, that the base plate has an upwardly directed to the mast, substantially circular curvature.

Durch die erfindungsgemäß vorgesehene Wölbung in der Fußplatte kann diese wesentliche höhere Belastungen im Vergleich zu einer herkömmlichen, ebenen Fußplatte aufnehmen. Konsequenterweise kann die Dicke der Fußplatte bei konstanten Lasten verringert werden im Vergleich zu einer ebenen Fußplatte.By virtue of the curvature provided in the foot plate according to the invention, it can absorb substantially higher loads in comparison with a conventional, flat foot plate. Consequently, the thickness of the footplate at constant loads can be reduced compared to a flat footplate.

Gemäß einer Weiterbildung der Erfindung kann es vorgesehen sein, dass die Wölbung in den Eckbereichen der Fußplatte eine konkave Kontur aufweist. Durch diese entgegengesetzt zu der kreisförmigen Kontur der Wölbung gerichtete Form wird eine höhere Belastbarkeit der Fußplatte erreicht, zusätzlich ergibt sich im Eckbereich eine größere Auflagefläche für ein Befestigungsmittel wie eine Schraube.According to one embodiment of the invention, it may be provided that the curvature has a concave contour in the corner regions of the base plate. By this opposite to the circular contour of the curvature directed form a higher load capacity of the base plate is achieved, in addition, results in the corner of a larger bearing surface for a fastener such as a screw.

Bei dem erfindungsgemäßen Mast kann es vorgesehen sein, dass die Fußplatte in den Eckbereichen als Langlöcher ausgebildete Öffnungen aufweist. Durch die als Langlöcher ausgebildeten Öffnungen können Einbautoleranzen leichter ausgeglichen werden, wodurch die Montage des Masts erleichtert wird.In the mast according to the invention, it may be provided that the base plate has openings formed in the corner areas as slots. By designed as slots holes installation tolerances can be easily compensated, whereby the assembly of the mast is facilitated.

Gemäß einer bevorzugten Weiterbildung der Erfindung kann es vorgesehen sein, dass die Längsachse eines Langlochs näherungsweise diagonal zu den benachbarten Kanten der Fußplatte verläuft. Die Langlöcher sind so außerhalb der Wölbung angeordnet, dass die Längsachse der Langlöcher senkrecht zum Radius der kreisförmigen Wölbung verläuft.According to a preferred embodiment of the invention, it may be provided that the longitudinal axis of a slot extends approximately diagonally to the adjacent edges of the base plate. The oblong holes are arranged outside the curvature such that the longitudinal axis of the oblong holes runs perpendicular to the radius of the circular curvature.

Eine noch höhere Materialersparnis kann erzielt werden, wenn die Fußplatte des erfindungsgemäßen Masts eine zentrale kreisförmige Öffnung aufweist. Der Durchmesser dieser Öffnung kann beispielsweise etwa ein Drittel der Seitenlänge der Fußplatte betragen.An even higher material savings can be achieved if the base plate of the mast according to the invention has a central circular opening. The diameter of this opening may be, for example, about one third of the side length of the foot plate.

Bei dem erfindungsgemäßen Mast kann die Fußplatte eine Dicke von 8 bis 12 mm, insbesondere 10 mm, aufweisen. Diese Dicke gilt für normale Masten, die beispielsweise als Lichtmast verwendet werden, in Abhängigkeit des beabsichtigten Einsatzzwecks und der auftretenden Lasten kann die Dicke der Fußplatte angepasst werden, sie liegt jedoch in jedem Fall wesentlich unterhalb der Dicke einer herkömmlichen, ebenen Fußplatte.In the mast according to the invention, the base plate may have a thickness of 8 to 12 mm, in particular 10 mm. This thickness applies to normal masts, which are used, for example, as a light pole, depending on the intended use and the loads occurring, the thickness of the base plate can be adjusted, but it is in any case substantially below the thickness of a conventional, flat base plate.

Es liegt auch im Rahmen der Erfindung, dass die Wölbung der Fußplatte des erfindungsgemäßen Masts einen Biegeradius aufweist, der näherungsweise dem Zweifachen der Dicke der Fußplatte entspricht. Durch den vorgesehenen vergleichsweise großen Biegeradius erhöht sich die Belastbarkeit der Fußplatte. Bei einer bevorzugten Ausführungsform des erfindungsgemäßen Masts kann es vorgesehen sein, dass der Biegeradius 16 bis 24 mm, insbesondere 20 mm, beträgt.It is also within the scope of the invention that the curvature of the base plate of the mast according to the invention has a bending radius which corresponds approximately to twice the thickness of the base plate. The provided comparatively large bending radius increases the load capacity of the foot plate. In a preferred embodiment of the mast according to the invention it can be provided that the bending radius is 16 to 24 mm, in particular 20 mm.

Die Fußplatte des erfindungsgemäßen Masts besteht vorzugsweise aus Stahl, sie kann auch eine Korrosionsschutzschicht aufweisen, die durch Verzinken aufgebracht ist, alternativ kann die Fußplatte auch eine Lackschicht aufweisen. Die Fußplatte ist mit dem Mast vorzugsweise verschweißt.The base plate of the mast according to the invention is preferably made of steel, it may also have a corrosion protection layer which is applied by galvanizing, alternatively, the foot plate may also have a lacquer layer. The footplate is preferably welded to the mast.

Weitere Vorteile und Einzelheiten der Erfindung werden nachfolgend anhand eines Ausführungsbeispiels unter Bezugnahme auf die Zeichnungen erläutert. Die Zeichnungen sind schematische Darstellungen und zeigen:

Further advantages and details of the invention will be explained below with reference to an embodiment with reference to the drawings. The drawings are schematic representations and show:

a plan view of a foot plate of in Fig. 1 masts shown;
Fig. 3
a section through the in Fig. 2 foot plate shown along the line III-III; and
Fig. 4
a section through the in Fig. 2 foot plate shown along the line IV-IV.

Der in Fig. 1 gezeigte Mast 1 besteht im Wesentlichen aus einem Mastkörper 2, der an seinem unteren Ende eine Fußplatte 3 aufweist. Der konische Mastkörper 2 und die Fußplatte 3 sind miteinander verschweißt. An dem oberen, nicht dargestellten Ende des Masts 1 befindet sich eine Beleuchtungseinrichtung, sodass der Mast 1 als Lichtmast verwendet werden kann.The in Fig. 1 Mast 1 shown essentially consists of a mast body 2, which has a base plate 3 at its lower end. The conical mast body 2 and the base plate 3 are welded together. At the upper, not shown end of the mast 1 is a lighting device, so that the mast 1 can be used as a light pole.

Die in Fig. 2 in einer Draufsicht gezeigte Fußplatte 3 weist eine quadratische Grundform auf. Die Fußplatte 3 besitzt eine aufwärts, zum Mastkörper 2 gerichtete Wölbung 4, an die sich eine ringförmige ebene Fläche 5 anschließt, die von der Wölbung 4 umgeben ist. Nach der Herstellung der Fußplatte 3 wird diese mit dem Mastkörper 2 auf der Fläche 5 verschweißt. Die ebene Fläche 5 weist eine zentrale, kreisförmige Öffnung 6 auf.In the Fig. 2 Foot plate 3 shown in a plan view has a square basic shape. The base plate 3 has an upwards, directed to the mast body 2 buckle 4, to which an annular flat surface 5 connects, which is surrounded by the curvature 4. After the preparation of the base plate 3, this is with the Mast body 2 welded to the surface 5. The flat surface 5 has a central, circular opening 6.

In den Eckbereichen der Fußplatte 3 befindet sich jeweils ein Langloch 7, dessen Längsachse im Wesentlichen senkrecht zum Radius der Wölbung 4 verläuft.In the corner regions of the base plate 3 is in each case a slot 7 whose longitudinal axis is substantially perpendicular to the radius of the curvature 4.

Die Wölbung 4 weist in den Eckbereichen der Fußplatte 3 eine konkave Kontur 8 auf, die entgegengesetzt zu der Kontur der Wölbung 4 nach außen gekrümmt ist. Durch die konkave Kontur 8 wird der für ein Befestigungsmittel zur Verfügung stehende Raum im Bereich des Langlochs 7 vergrößert. Daneben wirkt sich die konkave Kontur 8 vorteilhaft auf die Belastbarkeit der Fußplatte 3 aus, die die Zug-und Druckkräfte abträgt, die über den Mastkörper 2 eingeleitet werden.The curvature 4 has in the corner regions of the base plate 3 a concave contour 8, which is opposite to the contour of the curvature 4 curved outward. The concave contour 8 increases the space available for a fastening means in the area of the oblong hole 7. In addition, the concave contour 8 has an advantageous effect on the load capacity of the base plate 3, which removes the tensile and compressive forces which are introduced via the mast body 2.

In dem dargestellten Ausführungsbeispiel ist die Fußplatte 3 aus Stahl hergestellt und verzinkt, sie weist eine Dicke von 10 mm auf. Die Wölbung 4 der Fußplatte 3 weist einen Biegeradius auf, der dem Zweifachen der Dicke der Fußplatte 3 entspricht, in dem dargestellten Ausführungsbeispiel beträgt der Biegeradius 20 mm.In the illustrated embodiment, the base plate 3 is made of steel and galvanized, it has a thickness of 10 mm. The curvature 4 of the foot plate 3 has a bending radius which corresponds to twice the thickness of the base plate 3, in the illustrated embodiment, the bending radius is 20 mm.
