Abstract

The light has a casing extending longitudinally. It can be turned about its longitudinal axis to different positions. The light (10) has at least two different technical lighting systems, independent of each other, so that by turning the light about its longitudinal axis (25), the beam direction from the lamps (21, 22) can be varied. It may be in the form of a ceiling fitting, possibly a suspended one. With the light turned to one position, the lamp of one system shines downwards and that of the other shines upwards. The other position is 180 degrees different and reverses the direction of the lamps.

Description

Die Erfindung betrifft einen Stahlrohrmast und ein Verfahren zur Erneuerung eines Stahlrohrmastes mit rundem Querschnitt, bei dem am oberen Ende mindestens eine Leuchte angebracht ist und im Inneren Stromversorgungsskabel verlaufen, bei dem ein Abklemmen des im Inneren des Mastes verlaufenden Stromversorgungskabels und ein Vorinstallieren von Leuchte und Kabel im neuen Mast sowie ein Verfüllen des Raumes zwischen den im Erdreich verbliebenen Reststücks des alten Mastes und neuen Mast mit einem Füllstoff und Verfestigen des Materials erfolgt.The invention relates to a tubular steel mast and a method for renewal of a tubular steel pole with a round cross-section, with the one at the top End at least one lamp is attached and power cable inside run, in which a pinching of the inside of the mast running power supply cable and a pre-installation of light and cables in the new mast and a filling of the space between the Soil remaining pieces of the old mast and new mast with a filler and solidifying the material.

Stahlrohrmaste unterliegen einem Verschleiß durch Korrosion, so daß nach einer Reihe von Jahren eine Erneuerung der Masten erforderlich ist. Die Korrosion kann durch Korrosionsschutzmittel wie Farbanstriche oder Verzinken und dergleichen zwar vermindert, aber nicht vermieden werden. Dabei treten die Korrosionserscheinungen in besonders starken Maße an der Austrittsstelle des Mastes aus dem Erdreich auf. Dies wird verursacht durch die Bildung von chemischen Lokalelemente. Steel tube masts are subject to wear due to corrosion, so that after A renewal of the masts is required for a number of years. The Corrosion can be caused by anti-corrosion agents such as paint or Galvanizing and the like may be reduced, but not avoided. The signs of corrosion occur particularly strongly on the Exit point of the mast from the ground. This is caused by the formation of local chemical elements.

Zur Erneuerung der verschlissenen Masten werden diese ausgegraben und durch einen neuen Mast ersetzt. Da die Masten in einem Betonfundament verankert sind, ist das Ausgraben des Mastes ein sehr arbeits- und zeitaufwendiger Prozess, bei dem der um den Mastbereich vorhandene Straßenbelag entfernt und anschließend wieder erneuert werden muss.To renew the worn masts, they are dug up and replaced by a new mast. Because the masts are in a concrete foundation are anchored, digging the mast is a very laborious and time-consuming process Process in which the road surface around the mast area removed and then replaced again.

In der Regel ist durch den Mast ein elektrisches Kabel geführt, das zum Beispiel zur Versorgung von Straßenbeleuchtungen erforderlich ist.
Beim Ausgraben des zu ersetzenden Mastes wird dieses Kabel häufig beschädigt, wodurch weitere aufwendige Reparaturarbeiten entstehen.As a rule, an electrical cable is routed through the mast, which is required, for example, to supply street lighting.
When digging out the mast to be replaced, this cable is often damaged, resulting in further complex repair work.

In SE - B - 500 645 ist eine Anordnung zur Montage eines Lichtmastes beschrieben, bei der der Lichtmast in einem älteren Mast montiert wird, wobei ein hülsenförmiges Zentrierteil in den älteren Mast eingesetzt wird. Das Zentrierteil weist axial angeordnete Rippen mit dazwischenliegenden Gelenkteilen auf.
Mit dieser Anordnung kann zwar das an einem altem Mast vorhandene Montagefundament genutzt werden. Die Verwendung eines speziellen Zentrierteiles ist jedoch sehr aufwendig und erfordert zusätzliche Sicherungsmaßnahmen.SE-B-500 645 describes an arrangement for mounting a light mast, in which the light mast is mounted in an older mast, a sleeve-shaped centering part being inserted into the older mast. The centering part has axially arranged ribs with intermediate joint parts.
With this arrangement, the mounting foundation existing on an old mast can be used. However, the use of a special centering part is very complex and requires additional security measures.

Ferner sind nach WO - A - 97 39212 und WO - A - 93 20312 Anordnungen und Verfahren zur Reparatur eines Mastes bekannt, bei denen der zu montierende Mast mit Hilfe eines zusätzlichen rohrförmigen Teiles im Fundament befestigt wird.Furthermore, according to WO-A-97 39212 and WO-A-93 20312 there are arrangements and methods for repairing a mast known in which the mounting mast with the help of an additional tubular part in the Foundation is attached.

Weiter ist in DE - A - 15 59 137 eine Mastanordnung angegeben, die aus zwei am Fußende ineinander gesteckten Schäften besteht, welche mittels in einem der Schäfte eingeschraubten und sich im gleichachsigen Bohrungen im anderem Schaft abstützenden Schrauben befestigt sind.Furthermore, in DE-A-15 59 137 a mast arrangement is specified which consists of consists of two shafts inserted into each other at the foot end, one of the shafts screwed in and in the same axis bores in other shaft supporting screws are attached.

Bei dem im Stand der Technik bekannten Anordnungen ist nachteilig, dass aufwendige zusätzliche Anordnungen zur Befestigung des Mastes erforderlich sind, die eine komplizierte und kostenaufwendige Montage erfordern.A disadvantage of the arrangements known in the prior art is that complex additional arrangements for fastening the mast required are that require a complicated and costly assembly.

Der Erfindung liegt die Aufgabe zugrunde, einen Mast anzugeben, mit dem eine Erneuerung eines vorhandenen Mastes in einfacher und kostengünstiger Weise ermöglicht wird.The invention has for its object to provide a mast with which a renewal of an existing mast in a simple and inexpensive way Way is made possible.

Erfindungsgemäß gelingt die Lösung mit den in den Patentansprüchen 1 und 4 angegebenen Merkmalen.According to the invention, the solution to those in claims 1 and 4 specified characteristics.

Vorteilhafte Ausgestaltungen des erfindungsgemäßen Stahlrohrmastes sind in den Unteransprüchen angegeben.Advantageous configurations of the tubular steel mast according to the invention are specified in the subclaims.

Bei der Erfindung ist das Erdstück des neuen Mastes so konstruiert, daß es in das im Erdreich verbleibende Erdstück des alten Mastes hineingeschoben werden kann.In the invention, the base of the new mast is designed so that it pushed into the soil of the old mast remaining in the ground can be.

Die Erfindung zeichnet sich durch eine Reihe von Vorteilen aus.The invention is characterized by a number of advantages.

Bei der Erneuerung eines Mastes nach dem erfindungsgemäßen Verfahren ist es nicht erforderlich, ein Fundament zu entfemen und ein neues anzubringen. Damit entfallen auch die sonst notwendigen Arbeiten zur Entfernung des Straßenbelages und zur Anbringung von neuen Belägen. Dies führt zu erheblichen Kosteneinsparungen sowie zu Zeiteinsparungen bei der Sanierung verschlissener Beleuchtungsanlagen. Das arbeitsaufwendige Ausgraben des alten Mastes entfällt, es ist lediglich erforderlich, den alten Mast an der Austrittsstelle aus dem Erdreich zu trennen. Die vorhandene Elektroinstallation kann wieder verwendet werden, da keine Beschädigungen durch das Ausgraben auftreten können.When renewing a mast using the method according to the invention it is not necessary to remove a foundation and install a new one. This also eliminates the otherwise necessary removal work of the road surface and for the application of new coverings. this leads to considerable cost savings as well as time savings during renovation worn lighting systems. The laborious digging the old mast is no longer required, it is only necessary to attach the old mast to the Separate exit point from the ground. The existing electrical installation can be used again since no damage caused by the Digging can occur.

    Der Lichtmast besteht aus einem Mastoberteil 1, welches entsprechend den Erfordernissen in Form, Lichtpunkthöhe und Mastkopfausbildung konstruiert worden ist. Das Erdstück 2 des neuen Mastes, welches in das im Erdreich verbleibende Reststück 7 des verschlissenen Mastes hineinpasst, wird in geeigneter Weise mit diesem Mastoberteil 1 verbunden. Danach wird der Mast in das im Erdreich verbleibende Reststück 7 des alten Mastes eingesetzt.The light pole consists of a mast top 1, which according to the Requirements in terms of shape, mounting height and mast head design has been. The base 2 of the new mast, which in the Soil remaining piece 7 of the worn mast fits into it, is connected in a suitable manner with this mast top 1. After that the mast in the remaining piece 7 of the old mast remaining in the ground used.

    Bei der in Figur 1 dargestellten zweiteiligen Ausführung besteht der Mast aus einem Mastoberteil 1, und dem Erdstück 2. Im dargestellten Beispiel ist das Erdstück 2 mit Punktschweißverbindungen 6 an dem Mastoberteil 1 befestigt. Das Erdstück 2 weist im unterem Bereich einen Kabeleinführungsschlitz 3 auf, damit es über das seitlich in den unteren Teil des Mastes eingeführte Stromversorgungskabel 4 geschoben werden kann. Der Schlitz ist mit abgerundeten Kanten versehen, um eine Beschädigung des Stromversorgungskabels 4 bei der Montage zu vermeiden. Das Erdstück 2 ist im Durchmesser so gestaltet, daß es in das im Erdreich verbliebene Reststück 7 des zu erneuernden Mastes eingeschoben werden kann.In the two-part embodiment shown in Figure 1, the mast is made from a mast top 1, and the base 2. In the example shown the base 2 with spot welds 6 on the mast top 1 attached. The base 2 has a cable entry slot in the lower area 3 so that it is inserted laterally into the lower part of the mast Power cable 4 can be pushed. The slot is with rounded edges to prevent damage to the power supply cable 4 to avoid during assembly. The base 2 is in diameter designed so that it remains in the remaining piece of soil 7 of the renewing mast can be inserted.

    Figur 2 erläutert eine Ausführungsform, bei der Mast einteilig gestaltet ist. Hierbei weist dieser im unterem Bereich, der sich im Erdreich befindet, einen geringeren Durchmesser auf als das oberhalb des Erdreiches angeordnete Mastoberteil 1. Die Durchmesserverringerung ist dabei so dimensioniert, daß der Außendurchmesser des neuen Mastes in seinem unteren Bereich geringer als der Innendurchmesser des zu erneuernden Mastes ausgeführt ist und daß sich die Außendurchmesser des zu erneuernden Mastes im Bereich über der Erdoberkante 10 und der Außendurchmesser des im Erdreich verbliebenen Reststücks 7 des zu erneuernden Mastes entsprechen. Dadurch kann der neue Mast einerseits problemlos in das im Erdreich verbliebene Reststück 7 des alten Mastes eingefügt werden und andererseits die Last von diesem Unterteil aufgenommen werden. Der feste Sitz und die exakte Position des neuen Mastes im Reststück 7 des alten Mastes wird durch einen hierbei als Füllmaterial 8 dienenden Füllstoff erreicht.Figure 2 illustrates an embodiment in which the mast is designed in one piece. This has one in the lower area, which is located in the ground smaller diameter than that arranged above the ground Mast upper part 1. The diameter reduction is dimensioned so that the outer diameter of the new mast is lower in its lower area than the inside diameter of the mast to be replaced and that the outside diameter of the mast to be renewed in the area above Upper edge 10 and the outer diameter of the remaining in the soil Corresponding remaining piece 7 of the mast to be renewed. This allows the new mast on the one hand without problems in the remaining piece 7 in the ground of the old mast and on the other hand the load of this Lower part can be included. The tight fit and the exact position of the new mast in the remnant 7 of the old mast is here by a Filler 8 serving filler reached.

    Der Austausch eines zu erneuernden Lichtmastes erfolgt im wesentlichen mit den in den Figuren 3 bis 6 dargestellten vier Schritten.The replacement of a light pole to be renewed essentially takes place with the four steps shown in Figures 3 to 6.

    Als Voraussetzung zur Erneuerung wird zunächst die statische Festigkeit des alten Fundamentes überprüft.
    In dem in Figur 3 gezeigten ersten Schritt wird der zu ersetzende Mast für die Demontage vorbereitet. Die gesamte Anlage wird hierzu zunächst vom Stromnetz getrennt. Danach wird der Mast gegen Umkippen gesichert. Hierzu wird durch Anbringen einer Sicherung am Mastkopf, was zweckmäßigerweise mit einer Spezialvorrichtung und einem Kran erfolgt. Das Stromversorgungskabel wird am Kabelkasten getrennt und in das im Erdreich verbliebene Reststück des Mastes zurückgeschoben.    As a prerequisite for renewal, the static strength of the old foundation is first checked.
    In the first step shown in Figure 3, the mast to be replaced is prepared for disassembly. For this purpose, the entire system is first disconnected from the power grid. The mast is then secured against tipping over. This is done by attaching a fuse to the mast head, which is conveniently done with a special device and a crane. The power supply cable is disconnected at the cable box and pushed back into the remaining part of the mast that remains in the ground.

    In dem sich anschließenden zweiten Schritt gemäß Figur 4 wird der Mast entfernt. In manchen Fällen ist es hierzu zweckmäßig, den zu entfernenden Mast in einer Tiefe von ca. 20 cm freizulegen, damit die Trennstelle unterhalb der Erdoberkante liegt. Es ist jedoch auch ohne weiters möglich, den Mast oberhalb der Erdoberkante abzuschneiden, z.B. um die Straßenoberfläche nicht zu beschädigen. Der Mast wird danach mit Hilfe eines Spezialwerkzeuges vom Erdstück getrennt. Hierbei wird er mit der oben beschriebenen Halterung von einem Kran gehalten und nach dem Abschneiden seitlich abgelegt.
    Um Beschädigungen des Stromversorgungskabels 3 zu vermeiden, werden die Ränder gratfrei geschliffen, so daß sie eine saubere Schnittkante aufweisen. In dieser Bearbeitungsphase ist das Erdstück des zu ersetzenden Mastes freigelegt. Ein besonderer Vorteil des erfindungsgemäßen Verfahrens ist, daß das sich im Erdreich befindende Reststück des auszuwechselnden Mastes dort verbleiben kann und als Hülse zur Befestigung für den neuen Mast verwendet werden kann. Der sich im Inneren dieses Maststückes ergebende Hohlraum wird freigeräumt und gesäubert. Die Durchtrittsstelle, in der das Erdkabel in den Mast eintritt, ist damit gut sichtbar und kann markiert werden. Für eine komplikationsfreie Montage ist die exakte Ausrichtung des neuen Mastes wichtig. Der Kabeleinführungsschlitz 3 des Erdstückes muss genau über den Kabelausgangsloch des alten Mastes eingeführt werden. Die Enden der Kabeleinführung sind abgerundet um das Kabel 4 nicht zu beschädigen. Zur Erhöhung der Sicherheit gegen Beschädigungen des Kabels 4 ist es vorteilhaft, dieses mit einer Schutzhülle aus Kunststoff, z.B. mit einem Flexrohr, zu versehen Die Schutzhülle kann gegebenenfalls nach Beendigung der Maßnahme wieder entfernt und erneut verwendet werden.    In the subsequent second step according to FIG. 4, the mast is removed. In some cases it is useful to expose the mast to be removed at a depth of approx. 20 cm so that the separation point is below the top of the earth. However, it is also easily possible to cut the mast above the top of the earth, for example in order not to damage the road surface. The mast is then separated from the ground using a special tool. Here it is held by a crane using the bracket described above and placed laterally after being cut off.
    In order to avoid damage to the power supply cable 3, the edges are ground without burrs so that they have a clean cutting edge. In this processing phase, the base of the mast to be replaced is exposed. A particular advantage of the method according to the invention is that the remaining piece of the mast to be replaced can remain there in the ground and can be used as a sleeve for fastening the new mast. The cavity that arises inside this mast piece is cleared and cleaned. The passage point at which the underground cable enters the mast is thus clearly visible and can be marked. The exact alignment of the new mast is important for complication-free assembly. The cable entry slot 3 of the base must be inserted exactly over the cable exit hole of the old mast. The ends of the cable entry are rounded so as not to damage the cable 4. In order to increase the security against damage to the cable 4, it is advantageous to provide it with a protective cover made of plastic, for example with a flexible tube.

    In dem in Figur 5 gezeigten, sich anschließenden dritten Schritt erfolgt das Aufstellen des neuen Mastes. Hierzu wird der Mast zunächst vorinstalliert, indem er mit der Leuchte und dem Stromzuführungskabel versehen wird. Danach erfolgt das Ausrichten. Mit Hilfe des Kranes und der daran angebrachten Hilfsvorrichtung wird er in der erforderliche Höhen- und Drehlage positioniert und langsam in die von alten Mast noch vorhandene Erdhülse bis zu einer vorgesehenen Markierung, mit der die erforderliche Höhenpostion gekennzeichnet wurde, eingeschoben.
    Danach wird der Mast in die genaue vertikale Position gebracht und der freie Raum zwischen Erdhülse und neuem Mast sowie der Innenraum des Mastunterteiles mit einem geeignetem Füllstoff, vorzugsweise mit Quarzsand, aufgefüllt und verfestigt. Als Verfüllmasse können Sand, Mörtel, Magerbeton, Kunststoffe oder sonstige handelsübliche Baumaterialien verwendet werden.
    Bei Bedarf kann der Mast im Bereich des Erdübergangs mit einen Schutzanstrich oder einer Mastkaschierung versehen werden.    In the subsequent third step shown in FIG. 5, the new mast is set up. For this purpose, the mast is first pre-installed by providing it with the lamp and the power supply cable. Then the alignment takes place. With the help of the crane and the auxiliary device attached to it, it is positioned in the required height and rotation position and slowly inserted into the earth sleeve still present from the old mast up to a designated mark with which the required height position was identified.
    The mast is then brought into the exact vertical position and the free space between the ground sleeve and the new mast as well as the interior of the lower mast part is filled with a suitable filler, preferably with quartz sand, and solidified. Sand, mortar, lean concrete, plastics or other commercially available building materials can be used as backfill.
    If necessary, the mast can be provided with a protective coating or mast lamination in the area of the ground transition.

    Figur 6 erläutert den abschließenden vierten Schritt zur Komplettierung des Mastes. Das vorhandene Erdkabel kann wieder am Kabelanschlußkasten 5 angeschlossen und die Anlage freigeschaltet werden. Gegebenenfalls wird noch eine Angleichung des Mastbereiches an die Umgebung, z.B. durch Pflasterarbeiten, vorgenommen. Figure 6 explains the final fourth step to complete the Mastes. The existing underground cable can be connected to the cable junction box 5 connected and the system activated. If necessary another adjustment of the mast area to the environment, e.g. by Paving, made.
