Furthermore a pole which is particularly suitable for the pole construction according to the invention, together with a corresponding foundation element, are described. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Mastkonstruktion.The invention relates to a mast construction.

Durch die DE-A-20 14 345 ist eine Mastkonstruktion bekannt, bei der der Mast mit seinem Fuß auf einen Gründungskörper überlappend aufschiebbar ist. Im Mastfuß ist ein Aufsetzstab eingesetzt, durch den die Überlappungslänge von Mastfuß und Gründungskörper begrenzbar ist. Nach dem Aufstecken des Mastes auf den Gründungskörper wird der Mast auf nicht näher beschriebene Weise durch Pendeln um seinen Aufsetzstab ausgerichtet. Das Ausrichten des Mastes kann auf bekannte Weise z.B. mittels eines speziellen hydraulischen Masteinrichtgerätes oder mit einem Stellbock erfolgen. Bei dem Masteinrichtgerät handelt es sich um einen Bagger mit hydraulischer Zange, die den Mastkörper greift. Der Stellbock ist als Zweibein-Konstruktion ausgeführt, dessen Schellen den Mastkörper umfassen und dessen Klauen an den Schienen befestigt sind. Der Mastkörper ist so gegen die Schiene abgesteift. Die Ausrichtung des Mastes erfolgt durch Verstellen der Spannschlösser in den Beinen des Stellbockes. Anschließend wird der Zwischenraum zwischen Gründungskörper und Mastfuß vergossen. Der Einsatz des Masteinrichtgerätes erfordert schnell bindenden Mörtel, der jedoch in wärmeren Zonen, z.B. Südeuropa, nicht verwendet werden kann. Bei einer Mastausrichtung durch Stellböcke kann zwar auf schnellbindenden Mörtel verzichtet werden, während des Abbindens ist jedoch darauf zu achten, daß möglichst keine Vibrationen von den Schienen über die Zweibein-Konstruktion auf die Mastkonstruktion übertragen werden, da sonst unter Umständen dauernde Schäden an der ausgehärteten Mörtelfüllung auftreten können.From DE-A-20 14 345 a mast construction is known in which the mast can be pushed overlapping with its foot on a foundation body. A support rod is used in the mast base, which can be used to limit the overlap length of the mast base and foundation body. After placing the mast on the foundation body, the mast is aligned in a manner not described in more detail by swinging around its mounting rod. The mast can be aligned in a known manner, for example by means of a special hydraulic mast set-up device or using an adjusting block. The mast set-up device is an excavator with hydraulic tongs that grips the mast body. The jack is designed as a bipod construction, the clamps encompass the mast body and the claws are attached to the rails. The mast body is braced against the rail. The mast is aligned by adjusting the turnbuckles in the legs of the trestle. Then the space between the foundation body and mast base is poured. The use of the mast set-up device requires fast-setting mortar, which, however, cannot be used in warmer zones, e.g. southern Europe. If the mast is aligned using jacks, quick-setting mortar can be dispensed with, but during setting it is important to ensure that no vibrations are transmitted from the rails to the mast structure via the bipod construction, since otherwise permanent damage to the hardened mortar filling may occur may occur.

Durch das DE-U-1 769 593 ist ein Mastsockel aus Schleuderbeton für profilierte Beleuchtungsmasten bekannt, dessen zylindrischer Innenraum Nuten enthält. In diese Nuten sind die Kanten des eingesteckten Mastes mit Spiel geführt. Die Ausrichtung des Mastes erfolgt durch am Umfang des Sockels verteilt angeordnete Stellschrauben. In der inneren Wandung des Mastsockels sind Anschläge zur Begrenzung der Einstecktiefe des Mastes angeordnet. Diese Anschläge sind vorzugsweise in Form einer senkrecht zur Mastachse liegenden festen Scheibe mit einer mittigen Öffnung für elektrische Anschlußleitungen ausgebildet.From DE-U-1 769 593 a mast base made of centrifugal concrete for profiled lighting masts is known, the cylindrical interior of which contains grooves. The edges of the inserted mast are guided with play in these grooves. The mast is aligned using set screws distributed around the circumference of the base. Stops to limit the insertion depth of the mast are arranged in the inner wall of the mast base. These stops are preferably designed in the form of a fixed disc lying perpendicular to the mast axis with a central opening for electrical connecting lines.

Aufgabe der vorliegenden Erfindung ist es, eine Mastkonstruktion zu schaffen, bei der der Mast auf einfache Weise, insbesondere unabhängig von Hilfsgeräten, auf seinem Gründungskörper fixierbar ist.The object of the present invention is to provide a mast construction in which the mast can be fixed on its foundation body in a simple manner, in particular independently of auxiliary devices.

Die Aufgabe wird erfindungsgemäß durch die im Anspruch 1 angegebenen Merkmale gelöst. Vorteilhafte Ausgestaltungen sind in den Unteransprüchen beschrieben.The object is achieved by the features specified in claim 1. Advantageous configurations are described in the subclaims.

Durch die erfindungsgemäße Mastkonstruktion ist ein Mast mit einem nach unten offenen Fuß nach dem Aufschieben auf einen Gründungskörper durch einen Anschlag in seiner Höhenlage festgelegt und kann dann ohne Hilfsgeräte, wie z.B. Masteinrichtgeräte oder Stellböcke, auf dem Gründungskörper fixiert werden. Die fixierte Ausrichtung des Mastes erfolgt mittels einer radialen Abstandshaltevorrichtung, durch die der relative Abstand zwischen dem Innenmantel des Mastfußes und dem Außenmantel des Gründungskörpers festgelegt wird. Die erfindungsgemäße Mastkonstruktion kann sowohl bei Oberleitungsmasten, die im allgemeinen eine Überlotung (bei geradem Schienenverlauf von den Schienen weggeneigt) erfordern, als auch bei Freileitungsmasten, bei denen keine Überlotung erfolgt, angewandt werden. Darüber hinaus kann der Mast selbst als Hohl- oder als Vollkörper ausgebildet sein sowie aus verschiedenen Materialien bestehen und beliebige Querschnitte aufweisen. Auch bei einer Ausführung des Mastes als Vollkörper muß der Mastfuß jedoch als nach unten offener Mantel ausgebildet sein.By means of the mast construction according to the invention, a mast with a foot that is open at the bottom is fixed in height by a stop after being pushed onto a foundation body and can then be fixed on the foundation body without auxiliary devices, such as mast set-up devices or trestles. The mast is fixed in position by means of a radial spacing device, by means of which the relative distance between the inner jacket of the mast base and the outer jacket of the foundation body is determined. The mast construction according to the invention can be used both for overhead line masts, which are generally over-soldered (with a straight track of the rails tilted away), as well as for overhead line pylons where no over-soldering takes place. In addition, the mast itself can be designed as a hollow or solid body, can consist of different materials and can have any cross sections. Even if the mast is designed as a full body, the mast base must, however, be designed as an open jacket.

Durch die Verwendung von radial festen Abstandselementen wird der relative Mindestabstand zwischen Außenmantel des Gründungskörpers und Innenmantel des Mastfußes festgelegt. Durch die zusätzliche Verwendung von radial verstellbaren Abstandselementen wird der Mast in seine Sollage ausgerichtet.The use of radially fixed spacing elements defines the relative minimum distance between the outer jacket of the foundation body and the inner jacket of the mast base. Due to the additional use of radially adjustable spacer elements, the mast is aligned in its target position.

Da erfindungsgemäß alle radial verstellbaren Abstandselemente oberhalb oder unterhalb aller radial festen Abstandselemente angeordnet sind, erfolgt die Ausrichtung des Mastes ausschließlich in einer Schnittebene, die nicht notwendigerweise horizontal liegen muß. Damit ist bei der erfindungsgemäßen Mastkonstruktion das Ausrichten des Mastes besonders genau und einfach möglich.Since, according to the invention, all radially adjustable spacer elements are arranged above or below all radially fixed spacer elements, the mast is aligned exclusively in a sectional plane which does not necessarily have to be horizontal. With the mast construction according to the invention, the alignment of the mast is particularly precise and simple.

Bei der in den FIG 1 und 4 gezeigten erfindungsgemäßen Mastkonstruktion wird für die Gründung eines Mastes 1 zunächst ein Gründungskörper 2, der einen Außenmantel 16 aufweist und vorzugsweise als Gründungsrohr ausgebildet ist, in das Erdreich eingerammt. Nach der Schaffung eines dem Platzbedarf des Mastes 1 entsprechenden Freiraumes wird der Mast 1 mit seinem nach unten offenen hohlen Fuß 3, der einen Innenmantel 15 aufweist, auf das Gründungsrohr 2 überlappend aufgeschoben. Zur Begrenzung der Überlappungslänge und damit zur Festlegung des Mastes 1 in seiner Höhenlage weist gemäß FIG 1 das Gründungsrohr 2 zwei sich radial nach außen erstreckende axiale Anschlagselemente 4 auf, die einander gegenüberliegend am Außenmantel 16 des Gründungsrohres 2 angeordnet sind. In FIG 4 ist als axialer Anschlag zur Festlegung der Höhenlage des Mastes 1 ein Aufsetzstab 13 vorgesehen, der im Mastfuß 3 angeordnet ist.In the mast construction according to the invention shown in FIGS. 1 and 4, a foundation body 2, which has an outer jacket 16 and is preferably designed as a foundation tube, is first rammed into the ground for the foundation of a mast 1. After creating a space corresponding to the space required by the mast 1, the mast 1 with its hollow base 3, which is open at the bottom and has an inner jacket 15, is pushed onto the foundation tube 2 in an overlapping manner. In order to limit the length of overlap and thus to fix the mast 1 in its vertical position, according to FIG. 1, the foundation tube 2 has two axial stop elements which extend radially outwards 4, which are arranged opposite one another on the outer jacket 16 of the foundation tube 2. In FIG. 4, an attachment rod 13 is provided as an axial stop for fixing the height of the mast 1, which is arranged in the mast base 3.

Die fixierte Ausrichtung des Mastes 1 erfolgt mittels einer radialen Abstandshaltevorrichtung, durch die der relative Abstand zwischen Innenmantel 15 des Mastfußes 3 und Außenmantel 16 des Gründungsrohres 2 festgelegt wird. In vorteilhafter Weise umfaßt die erfindungsgemäße Abstandshaltevorrichtung radial feste und radial verstellbare Abstandselemente. Die radial verstellbaren Abstandselemente sind als Einstellschrauben 8 ausgebildet und über Gewindebuchsen 9 im Mastfuß 3 geführt. Sie können entweder oberhalb (FIG 1) oder unterhalb (FIG 4) der radial festen Abstandselemente angeordnet sein. Die beiden radial festen Abstandselemente sind in dem in FIG 1 dargestellten Ausführungsbeispiel als sich in axialer Richtung erstreckende, keilförmige Rippen 5 ausgebildet. Zusätzlich zu den beiden keilförmigen Rippen 5 sind zwei Mindestabstandselemente 6 vorgesehen. Sowohl die keilförmigen Rippen 5 als auch die Mindestabstandselemente 6 sind am Außenmantel 16 des Gründungsrohres 2 angeordnet. Die Basisbreite der keilförmigen Rippen 5 entspricht mindestens der lichten Weite zwischen dem Außenmantel 16 des Gründungsrohres 2 und dem Innenmantel 15 des Mastfußes 3. Die Mindestabstandselemente 6 sind als gerade Kreiszylinder ausgebildet und verlaufen parallel zu den keilförmigen Rippen 5. Der Durchmesser der Mindestabstandselemente 6 ist hierbei kleiner als die lichte Weite zwischen Außenmantel 16 des Gründungsrohres 2 und Innenmantel 15 des Mastfußes 3. Durch die spezielle Ausgestaltung der Mindestabstandselemente wird der Spielraum zum Neigen des Mastes 1 vergrößert und damit das Überloten des Mastes 1 vereinfacht. Darüber hinaus wird sichergestellt, daß ein nahezu vollständiges Umfließen des Gründungsrohres 2 mit Zementmörtel möglich ist.The fixed orientation of the mast 1 takes place by means of a radial spacing device, by means of which the relative distance between the inner jacket 15 of the mast base 3 and the outer jacket 16 of the foundation tube 2 is determined. The spacer device according to the invention advantageously comprises radially fixed and radially adjustable spacer elements. The radially adjustable spacer elements are designed as adjusting screws 8 and guided via threaded bushings 9 in the mast base 3. They can be arranged either above (FIG. 1) or below (FIG. 4) the radially fixed spacer elements. In the exemplary embodiment shown in FIG. 1, the two radially fixed spacer elements are designed as wedge-shaped ribs 5 which extend in the axial direction. In addition to the two wedge-shaped ribs 5, two minimum spacing elements 6 are provided. Both the wedge-shaped ribs 5 and the minimum spacing elements 6 are arranged on the outer jacket 16 of the foundation tube 2. The base width of the wedge-shaped ribs 5 corresponds at least to the clear width between the outer jacket 16 of the foundation tube 2 and the inner jacket 15 of the mast base 3. The minimum spacing elements 6 are designed as straight circular cylinders and run parallel to the wedge-shaped ribs 5. The diameter of the minimum spacing elements 6 is here smaller than the clear width between the outer jacket 16 of the foundation tube 2 and the inner jacket 15 of the mast base 3. The special design of the minimum spacing elements increases the scope for tilting the mast 1 and thus simplifies over-soldering of the mast 1. In addition, it is ensured that an almost complete flow around the foundation pipe 2 with cement mortar is possible.

Da bei dem in FIG 1 und 2 dargestellten Ausführungsbeispiel der Mast 1 und das Gründungsrohr 2 einen kreisförmigen Querschnitt aufweisen, sind für eine fixierte Ausrichtung des Mastes 1 lediglich zwei gegenüberliegende keilförmige Rippen 5 und zwei, um 90° zu den Rippen 5 versetzt angeordnete Mindestabstandselemente 6 sowie drei Einstellschrauben 8 erforderlich. Wie in FIG 2 gezeigt, liegt hierbei eine der Einstellschrauben vorzugsweise in der Ebene der Überlotungsachse, in der auch die beiden Mindestabstandselemente 6 liegen; die beiden anderen Einstellschrauben sind überlotungsseitig etwa in einem Winkel von 90° zueinander symmetrisch zur Ebene der Überlotungsachse angeordnet.Since the mast 1 and the foundation tube 2 have a circular cross section in the exemplary embodiment shown in FIGS and three adjusting screws 8 required. As shown in FIG. 2, one of the adjusting screws preferably lies in the plane of the soldering axis in which the two minimum spacing elements 6 are also located; the two other adjusting screws are arranged on the soldering side at an angle of approximately 90 ° to one another symmetrically to the plane of the soldering axis.

In vorteilhafter Weise ist in dem in FIG 1 und 2 dargestellten Ausführungsbeispiel jeweils eines der sich radial nach außen erstreckenden axialen Anschlagselemente 4 Bestandteil einer der keilförmigen Rippen 5. Eine keilförmige Rippe 5 und ein axiales Anschlagselement 4 bilden also jeweils ein L-förmiges Abstandselement 7.In the exemplary embodiment shown in FIGS. 1 and 2, one of the radially outwardly extending axial stop elements 4 is advantageously part of one of the wedge-shaped ribs 5. A wedge-shaped rib 5 and an axial stop element 4 therefore each form an L-shaped spacer element 7.

Für eine nochmals vereinfachte vertikale Ausrichtung des Mastes 1 sind die Auflageflächen 10 der axialen Anschlagselemente 4 quer zu ihrer Erstreckungsrichtung gewölbt ausgebildet. Durch derart gewölbte Auflageflächen läßt sich der Mast 1 sehr genau in seiner vertikalen Lage ausrichten. Darüber hinaus wird ein Verkanten des Mastfußes 3 auf der Auflagefläche 10 und damit Abplatzungen am Mastfuß 3 zuverlässig verhindert.For a further simplified vertical alignment of the mast 1, the contact surfaces 10 of the axial stop elements 4 are arched transversely to their direction of extension. Through such curved bearing surfaces, the mast 1 can be aligned very precisely in its vertical position. In addition, tilting of the mast base 3 on the support surface 10 and thus flaking on the mast base 3 is reliably prevented.

Bei der in FIG 4 dargestellten Mastkonstruktion sind als radial feste Abstandselemente drei flexible Abstandshalter 14 vorgesehen, die oberhalb der Einstellschrauben 8 angeordnet sind. Die Einstellschrauben 8 sind wiederum wie in FIG 2 beschrieben in bzw. zur Ebene der Überlotungsachse angeordnet. Die flexiblen Abstandshalter 14 sind auf das Gründungsrohr 2 aufsteckbar und erstrecken sich in Richtung der Längsachse des Gründungsrohres 2. Sie weisen eine vorgespannte radiale Ausformung auf, die um ein vorgegebenes Maß größer ist als die lichte Weite zwischen Außenmantel 16 des Gründungsrohres 2 und Innenmantel 15 des Mastfußes 3. Beim Aufschieben des Mastes 1 auf sein Gründungsrohr 2 führt dieses Übermaß zu einer Klemmwirkung, durch die der relative Abstand zwischen Innenmantel 15 des Mastfußes 3 und Außenmantel 16 des Gründungsrohres 2 festgelegt wird. Bei der Verwendung von wenigstens drei flexiblen Abstandshaltern 14 sind, im Gegensatz zu dem in den FIG 1-3 gezeigten Ausführungsbeispiel, keine Mindestabstandselemente 6 erforderlich.In the mast construction shown in FIG. 4, three flexible spacers 14 are provided as radially fixed spacing elements, which are arranged above the adjusting screws 8. The adjusting screws 8 are in turn arranged as described in FIG. 2 in or to the plane of the soldering axis. The flexible spacers 14 can be plugged onto the foundation tube 2 and extend in the direction of the longitudinal axis of the foundation tube 2. They have a prestressed radial shape, which is a predetermined amount larger than the clear width between the outer jacket 16 of the foundation tube 2 and the inner jacket 15 of the mast base 3. When pushing the mast 1 onto its foundation tube 2, this excess leads to a Clamping effect by which the relative distance between the inner jacket 15 of the mast base 3 and the outer jacket 16 of the foundation tube 2 is determined. When using at least three flexible spacers 14, in contrast to the exemplary embodiment shown in FIGS. 1-3, no minimum spacing elements 6 are required.

Nach dem fixierten Ausrichten des Mastes 1 durch die Einstellschrauben 8 wird durch eine oberhalb der Überlappung von Mastfuß 3 und Gründungsrohr 2 angeordnete Vergußöffnung 11 eine erhärtende Masse - bei einem Betonmast und einem Gründungsrohr aus Stahl, z.B. Zementmörtel entsprechender Konsistenz - von oben in den Raum zwischen Mast 1 und Gründungsrohr 2 gefüllt. Durch einen Außenrüttler kann der eingefüllte Mörtel anschließend verdichtet werden. Zusätzlich zum Raum zwischen Mast 1 und Gründungsrohr 2 kann auch das Gründungsrohr 2 selbst mit Zementmörtel oder dergleichen ausgefüllt werden. Man erhält damit eine nochmals verbesserte Stabilität der gesamten Mastkonstruktion.After the fixed alignment of the mast 1 by means of the adjusting screws 8, a hardening mass is placed through a casting opening 11 arranged above the overlap of the mast base 3 and the foundation tube 2 - in the case of a concrete mast and a foundation tube made of steel, e.g. Cement mortar of appropriate consistency - filled from above into the space between mast 1 and foundation pipe 2. The filled mortar can then be compacted using an external vibrator. In addition to the space between the mast 1 and the foundation tube 2, the foundation tube 2 itself can also be filled with cement mortar or the like. The stability of the entire mast construction is improved even further.
