Description

Die Erfindung betrifft eine Vorrichtung zur Verankerung von Kappen am Überbau von Bauwerken der im Oberbegriff des Anspruchs 1 angegebenen Gattung.The invention relates to a device for anchoring caps on the superstructure of buildings of the type specified in the preamble of claim 1.

In der DIN 18195 und der Vorschrift "BMV RIZ (Kap 14)" sind die technischen Anforderungen zur Verankerung von Kappen am Überbau von Bauwerken, insbesondere Brücken, festgelegt. Zur Verankerung dienen hauptsächlich Telleranker, die in den Beton des Überbaus eingebettet sind und jeweils einen Flansch aufweisen, der mit der Oberkante des Betons bündig ist. Darüber wird eine Dichtungsschicht aufgebracht, die sich in Längsrichtung durchgehend über den Überbau erstreckt. Jedem einbetonierten Flansch ist ein Losflansch zugeordnet, der unter Zwischenlage der Dichtungsschicht mittels einer Schraube an dem einbetonierten Flansch angeschraubt wird.DIN 18195 and the "BMV RIZ (Chapter 14)" stipulate the technical requirements for anchoring caps on the superstructure of structures, in particular bridges. For anchorage serve mainly plate anchors, which are embedded in the concrete of the superstructure and each having a flange which is flush with the upper edge of the concrete. In addition, a sealing layer is applied, which extends continuously over the superstructure in the longitudinal direction. Each concreted flange is associated with a loose flange, which is screwed with the interposition of the sealing layer by means of a screw on the cast-in flange.

Die Telleranker werden entsprechend der gestellten Anforderungen in einem Abstand bis zu 2,5 m voneinander angeordnet. Nachdem alle Telleranker gesetzt sind, wird der Kappenbeton gegossen, wobei innerhalb des Bauraums der Kappe eine geeignete Armierung vorgesehen ist. Auf die Kappe und den Überbau, beispielsweise der Überbau einer Brücke, wirken erhebliche Temperaturänderungen, wobei eine unterschiedliche Wärmeausdehnung von Kappe und Überbau auftritt. Da die bekannten Telleranker als starre Elemente den horizontalen Kräften bei unterschiedlicher Dehnung von Kappe und Überbau keinen Ausgleich gestatten, kann dies zu erheblichen Schäden des Bauwerks führen, die insbesondere an den Kappen auftreten.The plate anchors are arranged according to the requirements at a distance of up to 2.5 m from each other. After all plate anchors are set, the cap concrete is poured, wherein within the space of the cap a suitable reinforcement is provided. On the cap and the superstructure, for example, the superstructure of a bridge, act significant temperature changes, with a different thermal expansion of the cap and superstructure occurs. Since the known plate anchors as rigid elements the horizontal forces at different Stretching of the cap and superstructure allow no compensation, this can lead to significant damage to the structure, which occur in particular on the caps.

Der Erfindung liegt die Aufgabe zugrunde, eine Vorrichtung zur Verankerung von Kappen am Überbau von Bauwerken der gattungsgemäßen Art zu schaffen, die günstig herstellbar ist und durch die eine Einwirkung von horizontalen Kräften auf die Verankerungsmittel vermieden wird.The invention has for its object to provide a device for anchoring caps on the superstructure of buildings of the generic type, which is inexpensive to manufacture and by the action of horizontal forces on the anchoring means is avoided.

Diese Aufgabe wird durch eine Vorrichtung mit den Merkmalen des Anspruchs 1 gelöst.This object is achieved by a device having the features of claim 1.

Durch die erfindungsgemäße Anordnung eines Verformungskörpers, der den Ankerschaft umgibt, können horizontale Kräfte richtungsunabhängig kompensiert werden. Auch beim Einbau des Ankers mit dem Verformungskörper muss nicht auf eine bestimmte Ausrichtung geachtet werden, was die Montage vereinfacht.The inventive arrangement of a deformation body surrounding the armature shaft, horizontal forces can be compensated direction independent. Also, when installing the armature with the deformation body does not have to pay attention to a specific orientation, which simplifies installation.

Gemäß einer bevorzugten Ausgestaltung der Erfindung ist der Anker ein Bolzen, der zumindest an seinem dem Ankerkopf abgewandten Ende einen Gewindeabschnitt aufweist. Ein solcher Bolzen ist ein kostengünstiges Standardbauteil, das sich auf einfache Weise in der Ankeraufnahme befestigen lässt. Vorzugsweise ist an dem Anker ein Spannelement angeordnet, das zum Spannen des Loslagers gegen die Dichtschicht vorgesehen ist. Besonders einfach und kostengünstig ist dabei, dass das Spannelement eine auf dem Gewindeabschnitt des Bolzens angeordnete Mutter ist. Damit lässt sich die Spannkraft, mit der das Loslager gegen die Dichtschicht beaufschlagt wird, genau einstellen.According to a preferred embodiment of the invention, the armature is a bolt which has a threaded portion at least at its end facing away from the anchor head. Such a bolt is a low-cost standard component that can be easily attached in the anchor receptacle. Preferably, a clamping element is arranged on the armature, which is provided for clamping the movable bearing against the sealing layer. Particularly simple and inexpensive is that the clamping element is a nut arranged on the threaded portion of the bolt. This allows the clamping force with which the floating bearing is acted upon against the sealing layer, set exactly.

Um die Zahl der notwendigen Einzelteile zu reduzieren, ist es zweckmäßig, dass der Ankerkopf einstückig mit dem Ankerschaft ausgeführt ist. Dabei ist der Ankerkopf vorzugsweise als Sechskant ausgeführt, so dass gängige Werkzeuge zu dessen Montage benutzt werden können. Alternativ zur einstückigen Ausführung ist es jedoch auch möglich, dass der Anker eine Gewindestange ist, an deren äußerem Ende als Ankerkopf eine Mutter angeordnet ist. Eine solche Ausführung hat den Vorteil, dass auf den bereits montierten Ankerschaft der Verformungskörper aufgesteckt werden kann und danach die als Ankerkopf dienende Mutter aufgeschraubt wird.In order to reduce the number of necessary items, it is expedient that the anchor head is made in one piece with the anchor shaft. In this case, the anchor head is preferably designed as a hexagon, so that common tools can be used for its assembly. As an alternative to the one-piece design, however, it is also possible that the armature is a threaded rod, at the outer end of which a nut is arranged as the anchor head. Such a design has the advantage that can be plugged onto the already mounted anchor shank of the deformation body and then the serving as an anchor head nut is screwed.

Es ist weiterhin von Vorteil, dass am Ankerkopf eine Ankerplatte angeordnet ist, die an einer radialen Fläche des Verformungskörpers anliegt und einen größeren Durchmesser aufweist als das diesem zugewandten Ende des Verformungskörpers. Damit ergibt sich zwischen der Ankerplatte und dem Loslager ein Abschnitt, in den der Beton eindringen kann, so dass in vertikaler Richtung eine große Verankerungskraft gegeben ist. Die Ankerplatte weist eine derart große Öffnung, bezogen auf den Ankerschaft, auf, dass die Ankerplatte quer zum Ankerschaft begrenzt verschieblich ist. Bei einer horizontalen Bewegung des Betons der Kappe wird somit auch die Ankerplatte verschoben, so weit dies die Öffnung in der Ankerplatte gestattet.It is also advantageous that an anchor plate is arranged on the anchor head, which bears against a radial surface of the deformation body and has a larger diameter than the end facing the deformation of the body. This results between the anchor plate and the floating bearing a section into which the concrete can penetrate, so that in the vertical direction is given a large anchoring force. The anchor plate has such a large opening, with respect to the armature shaft, that the armature plate is displaceable transversely to the armature shaft. In a horizontal movement of the concrete of the cap thus also the anchor plate is moved, as far as this allows the opening in the anchor plate.

Um die Ankerplatte bei der Montage auf einfache Weise zentrisch zu positionieren, ist es vorteilhaft, dass der Verformungskörper an seiner.dem Ankerkopf zugewandten Stirnseite einen axialen Vorsprung aufweist und dieser Vorsprung in die Öffnung der Ankerplatte greift. Um eine mögliche Differenz der Querschnitte von Ankerkopf und Öffnung in der Ankerplatte zu überbrücken, ist zwischen der Ankerplatte und dem Ankerkopf eine Zwischenscheibe angeordnet, deren Außendurchmesser mindestens das 1,3fache, vorzugsweise etwa das 1,5fache des Durchmessers der Öffnung der Ankerplatte beträgt. Der Innendurchmesser der Zwischenscheibe ist dem Durchmesser des Ankerschaftes angepasst.In order to position the anchor plate in a simple manner during assembly in a simple manner, it is advantageous that the deformation body has an axial projection on its end face facing the anchor head, and this projection engages in the opening of the anchor plate. In order to bridge a possible difference in the cross sections of anchor head and opening in the anchor plate is between the anchor plate and the anchor head arranged an intermediate disc whose outer diameter is at least 1.3 times, preferably about 1.5 times the diameter of the opening of the anchor plate. The inner diameter of the washer is adapted to the diameter of the armature shaft.

Gemäß einer weiteren zweckmäßigen Ausgestaltung ist vorgesehen, dass der Verformungskörper an seinem dem Loslager benachbarten Ende eine radiale Erweiterung aufweist und den Außenumfang des Loslagers umschließt. Auf diese Weise ist auch auf der Höhe des Loslagers eine horizontale Bewegung des Betons der Kappe möglich, ohne den Anker zu beeinträchtigen. Der Verformungskörper besteht vorzugsweise aus einem Hartschaumstoff, insbesondere Polystyrol. Ein derartiges Material bietet ausreichende Formsteifigkeit beim Einbringen des Betons zur Herstellung der Kappe. Erst im Fall einer relativen Verschiebung der Kappe, bei der wesentlich größere Kräfte auftreten, erfolgt eine Verformung des Materials.According to a further expedient embodiment, it is provided that the deformation body has a radial extension at its end adjacent to the floating bearing and surrounds the outer circumference of the movable bearing. In this way, a horizontal movement of the concrete of the cap is also possible at the height of the movable bearing, without affecting the anchor. The deformation body is preferably made of a rigid foam, in particular polystyrene. Such a material provides sufficient stiffness in the introduction of the concrete for the production of the cap. Only in the case of a relative displacement of the cap, occur at the much larger forces, there is a deformation of the material.

Zur einfachen Montage des Ankers umfasst die Ankeraufnahme bevorzugt eine einbetonierte Hülse mit einem Innengewinde. Die Hülse ist zweckmäßigerweise mit einem einbetonierten Verankerungselement versehen, das an seinem der Hülse abgewandten Ende einen Kopf aufweist. Der Kopf dient dabei zur Erhöhung der Zugkraft in Längsrichtung des Ankers und sichert damit die Ankeraufnahme im Beton des Überbaus. Zur einfachen Verbindung des Verankerungselementes mit der Hülse weist das Verankerungselement einen Gewindeabschnitt auf, der in die Hülse geschraubt ist. Alternativ hierzu kann das Verankerungselement in einen Hülsenabschnitt ragen, wobei dieser Hülsenabschnitt mit dem Verankerungselement auf andere Weise fest verbunden, beispielsweise verpresst ist. Zur Lagesicherung des Verankerungselementes mit der Hülse beim Betonieren des Überbaus ist die Hülse mit einem Montageelement versehen, das mit einbetoniert wird.For easy installation of the anchor, the anchor receptacle preferably comprises a cast-in sleeve with an internal thread. The sleeve is expediently provided with a cast-in anchoring element which has a head at its end facing away from the sleeve. The head serves to increase the tensile force in the longitudinal direction of the anchor and thus secures the anchor seat in the concrete of the superstructure. For easy connection of the anchoring element with the sleeve, the anchoring element has a threaded portion which is screwed into the sleeve. Alternatively, the anchoring element protrude into a sleeve portion, said sleeve portion with the anchoring element firmly connected in other ways, for example, is pressed. To secure the position of the anchoring element with the sleeve during concreting the Superstructure, the sleeve is provided with a mounting element, which is embedded in concrete.

Für den Fall, dass an einem bereits fertigen Überbau noch zusätzliche Anker angeordnet werden sollen oder für den Fall von Sanierungsarbeiten ist es zweckmäßig, dass die Ankeraufnahme einen Dübel mit einer Gewindehülse umfasst. Ein solcher Dübel kann in eine Bohrung im Beton des Überbaus eingesetzt werden.In the event that additional anchors are to be arranged on an already completed superstructure or in the case of remedial work, it is expedient that the anchor receptacle comprises a dowel with a threaded sleeve. Such a dowel can be used in a hole in the concrete of the superstructure.

Um die Dichtheit der Anordnung im Bereich des Ankerabschnitts am vorderen Ende der Ankeraufnahme zu erhöhen, ist es vorteilhaft, dass unter dem Loslager zwischen der Dichtschicht und dem Überbau eine Lagerplatte angeordnet ist, deren Durchmesser ≥ dem Durchmesser des Loslagers ist. Diese Lagerplatte besitzt eine zentrische Öffnung, die auf den Außendurchmesser des Ankerschaftes abgestimmt ist. Durch die auf das Loslager wirkende Spannkraft wird bewirkt, dass das Material der Lagerplatte den Ankerschaft dichtend umschließt. Außerdem wird verhindert, dass die Dichtschicht durch Unebenheiten an der Betonoberfläche zerstört wird. Die Dicke der Lagerplatte beträgt zwischen 2 mm und 10 mm, vorzugsweise 3 mm. Die Lagerplatte besteht vorzugsweise aus einem polymerisierten Chloropren-Kautschuk. Alternativ hierzu kann unter dem Loslager zwischen der Dichtschicht und dem Überbau eine Dichtung aus einem bituminösen Material angeordnet sein.In order to increase the tightness of the arrangement in the region of the anchor portion at the front end of the anchor receptacle, it is advantageous that under the movable bearing between the sealing layer and the superstructure, a bearing plate is arranged whose diameter is ≥ the diameter of the movable bearing. This bearing plate has a central opening which is matched to the outer diameter of the armature shaft. By acting on the floating bearing clamping force causes the material of the bearing plate enclosing the armature shaft sealing. In addition, it is prevented that the sealing layer is destroyed by unevenness on the concrete surface. The thickness of the bearing plate is between 2 mm and 10 mm, preferably 3 mm. The bearing plate is preferably made of a polymerized chloroprene rubber. Alternatively, under the floating bearing between the sealing layer and the superstructure, a seal made of a bituminous material may be arranged.

An dem Gewindeabschnitt 19 ist auch eine als Spannelement 23 dienende Mutter angeordnet. Auf diese Weise kann eine vorbestimmte Kraft, mit der das Loslager 20 die Dichtschicht 21 belastet, eingestellt werden. Wie sich aus der Darstellung in Fig. 2 auch ergibt, ist der Durchmesser der Lagerplatte 22 etwas größer als der Durchmesser des Loslagers 20.Before the in Fig. 2 shown concrete the cap 2 is poured, a sealing layer 21 are applied to the top of the superstructure 1 and anchor 9 set. Between the sealing layer 21 and the upper side of the superstructure 1 8 bearing plates 22 may be arranged in the region of the sleeve 11 of the anchor receptacle, which consist for example of a polymerized chloroprene rubber. Such a bearing plate is for example between 2 mm and 10 mm thick, preferably the thickness is 3 mm. On the sealing layer 21 is located above the bearing plate 22, a floating bearing 20 with a central bore through which a threaded portion 19 of the armature 9 projects, wherein the armature 9 is screwed by means of this threaded portion 19 in the sleeve 11. At the threaded portion 19 and serving as a clamping element 23 nut is arranged. In this way, a predetermined force with which the floating bearing 20, the sealing layer 21 loaded, can be adjusted. As can be seen from the illustration in Fig. 2 Also, the diameter of the bearing plate 22 is slightly larger than the diameter of the movable bearing 20th

Der Anker 9 weist am oberen Ende des Ankerschaftes 17 einen Ankerkopf 18 auf, wobei es sich dabei um den Sechskantkopf einer handelsüblichen Schraube handelt. Der Ankerschaft 17 ist von einem Verformungskörper 10 umgeben, der einen hülsenförmigen Abschnitt 24 sowie eine radiale Erweiterung 25 und einen ringförmigen Abschnitt 26 umfasst. Die radiale Erweiterung 25 und der ringförmige Abschnitt 26 decken das Loslager 20 komplett ab und schließen dieses gemeinsam mit der darunter befindlichen Dichtschicht 21 ein. An dem oberen Ende des hülsenförmigen Abschnitts 24 befindet sich ein Vorsprung 27, so dass die Stirnseite des Verformungskörpers 10 einen Absatz bildet, an dem eine Ankerplatte 28 anliegt. Die Ankerplatte 28 weist eine Öffnung 29 auf, die wesentlich größer ist als der Durchmesser des Ankerschaftes 17, wobei der Vorsprung 27 dafür sorgt, dass die Ankerplatte 28 so positioniert ist, dass der Rand der Öffnung 29 überall den gleichen Abstand zum Ankerschaft 17 aufweist.The armature 9 has at the upper end of the armature shaft 17 an anchor head 18, which is the hexagonal head of a commercially available screw. The armature shaft 17 is surrounded by a deformation body 10, which comprises a sleeve-shaped portion 24 and a radial extension 25 and an annular portion 26. The radial extension 25 and the annular portion 26 cover the floating bearing 20 completely and include this together with the underlying sealing layer 21 a. At the upper end of the sleeve-shaped Section 24 is a projection 27, so that the end face of the deformation body 10 forms a shoulder on which an anchor plate 28 rests. The anchor plate 28 has an opening 29 which is substantially larger than the diameter of the armature shaft 17, wherein the projection 27 ensures that the anchor plate 28 is positioned so that the edge of the opening 29 has the same distance to the armature shaft 17 everywhere.

Zwischen dem Ankerkopf 18 und der Ankerplatte 28 befindet sich eine Zwischenscheibe 30, deren äußerer Durchmesser größer ist als der Querschnitt der Öffnung 29. Über dem Kopf 18 und der Zwischenscheibe 30 befindet sich ein Dichtelement 31, das auf der Oberseite der Ankerplatte 28 aufliegt und das Eindringen von Feuchtigkeit zwischen dem Ankerschaft 17 und dem Verformungskörper 10 verhindert. Um den Beton der Kappe entsprechend zu bewehren, sind in Längs- und Querrichtung verlaufende Bewehrungsstäbe 32 vorgesehen.Between the anchor head 18 and the anchor plate 28 is an intermediate disc 30 whose outer diameter is greater than the cross section of the opening 29. About the head 18 and the washer 30 is a sealing element 31 which rests on the top of the anchor plate 28 and the Ingress of moisture between the armature shaft 17 and the deformation body 10 prevented. In order to reinforce the concrete of the cap accordingly, extending in the longitudinal and transverse reinforcing bars 32 are provided.

Sofern Kräfte in horizontaler Richtung auf die Kappe 2 relativ zur Lage des Überbaus 1 einwirken, so wird der Verformungskörper 10 aufgrund seiner begrenzten Festigkeit auf der Seite zusammengedrückt, auf der die Kraft einwirkt, so dass eine Verschiebung der Kappe 2 möglich ist, ohne dass auf den Anker 9 nennenswerte Kräfte in Scherrichtung auftreten. Auch das Loslager 20 behält seine Lage bei, da hier der ringförmige Abschnitt 26 verformt wird. Ebenso kann die Ankerplatte 28 begrenzt in horizontaler Richtung verschoben werden, und zwar in dem Maße des Abstandes zwischen der Innenwandung der Öffnung 29 und dem Ankerschaft 17. Die jeweiligen Dimensionen des Verformungskörpers 10 werden unter Berücksichtigung der zu erwartenden relativen Bewegungen zwischen dem Überbau 1 und der Kappe 2 festgelegt.If forces acting in a horizontal direction on the cap 2 relative to the position of the superstructure 1, the deformation body 10 is compressed due to its limited strength on the side on which the force acts, so that a displacement of the cap 2 is possible without on the armature 9 significant forces occur in the shear direction. Also, the floating bearing 20 retains its location, since here the annular portion 26 is deformed. Likewise, the anchor plate 28 can be displaced limited in the horizontal direction, in the extent of the distance between the inner wall of the opening 29 and the armature shaft 17. The respective dimensions of the deformation body 10 are taking into account the expected relative movements between the superstructure 1 and Cap 2 set.

In Fig. 3 ist eine Ausführungsvariante zu Fig. 2 gezeigt, die sich lediglich bezüglich der Ankeraufnahme 8 von der zuvor beschriebenen Ausführung unterscheidet. Wie aus Fig. 3 ersichtlich ist, weist die Hülse 11 unterhalb des Montageelementes 16 einen Abschnitt 35 auf, durch den sich das Verankerungselement 33 erstreckt. Zur Verbindung der Hülse 11 mit dem Verankerungselement 33 wird der Abschnitt 35 mit dem Schaft des Verankerungselementes 33 verpresst. An seinem äußeren Ende weist das Verankerungselement 33 einen tellerförmigen Kopf 34 auf, der dazu beiträgt, die Haltekraft im Überbau zu erhöhen. Alle übrigen Teile in Fig. 3 stimmen mit denjenigen der Fig. 2 überein, so dass für gleiche Teile die selben Bezugzeichen verwendet sind.In Fig. 3 is a variant to Fig. 2 shown, which differs only with respect to the anchor seat 8 from the previously described embodiment. How out Fig. 3 it can be seen, the sleeve 11 below the mounting member 16 has a portion 35 through which the anchoring element 33 extends. To connect the sleeve 11 with the anchoring element 33, the portion 35 is pressed with the shank of the anchoring element 33. At its outer end, the anchoring element 33 has a plate-shaped head 34, which helps to increase the holding force in the superstructure. All remaining parts in Fig. 3 agree with those of Fig. 2 match, so that the same reference numerals are used for the same parts.

Die Fig. 4 zeigt eine perspektivische Darstellung eines Schnittes durch einen in einer Ankeraufnahme im Überbau befestigten Anker, das heißt im Zustand vor dem Betonieren der Kappe. Wie aus Fig. 4 ersichtlich ist, befindet sich in dem Überbau 1 eine Ankeraufnahme 8, die aus einer Hülse 36 und einem Gewindebolzen 37 mit endseitigem Kopf 38 besteht.

Auf der Dichtschicht 21 liegt das Loslager 20, durch dessen zentrische Öffnung ein als Gewindebolzen ausgeführter Ankerschaft 40 ragt, der in die Hülse 36 eingeschraubt ist. Der Ankerschaft 40 sowie das Loslager 20 sind von einem Verformungskörper 10 umgeben, der in etwa die gleiche Gestalt aufweist, wie derjenige in den Fig. 2 und 3. Am oberen Ende des Verformungskörpers 10 befindet sich die Ankerplatte 28, die von einem Ankerkopf 41 zur Anlage an dem Verformungskörper 10 gebracht wird.The Fig. 4 shows a perspective view of a section through an anchored in an anchor mount in the superstructure anchor, that is in the state before concreting the cap. How out Fig. 4 it can be seen, is located in the superstructure 1 an anchor receptacle 8, which consists of a sleeve 36 and a threaded bolt 37 with end-side head 38. On the top 39 of the superstructure 1 is already in Fig. 2 and 3 bearing plate 22 shown, over which the sealing layer 21 extends. On the sealing layer 21 is the movable bearing 20, through whose central opening designed as a threaded bolt anchor shaft 40 projects, which is screwed into the sleeve 36. The armature shaft 40 and the movable bearing 20 are surrounded by a deformation body 10, which has approximately the same shape as that in the Fig. 2 and 3 , At the upper end of the deformation body 10 is the anchor plate 28, which is brought by an anchor head 41 for abutment against the deformation body 10.

Die Fig. 5 zeigt eine Ausführungsvariante zu Fig. 4, bei der in dem Überbau 1 eine vertikale Bohrung 42 eingebracht ist. Diese vertikale Bohrung 42 dient zur Aufnahme eines Dübels 43, dessen der Oberseite 39 benachbarter Abschnitt als Hülse 44 ausgebildet ist und der an seinem weiter innen liegenden Abschnitt mit radial nach außen gerichteten Verformungen 45 in dem Überbau 1 gehalten wird. Wie bereits zu Fig. 4 beschrieben, befindet sich an der Oberseite 39 des Überbaus 1 die Lagerplatte 22, die den Ankerschaft 40 dichtend umschließt, und darüber erstreckt sich die Dichtschicht 21. Auf der Dichtschicht 21 liegt das Loslager 20, das von dem Spannelement 23 gegen die Dichtschicht 21 belastet wird. Der Verformungskörper 10 entspricht von der Form und Konsistenz demjenigen zu Fig. 4. Bei dem Ankerschaft 40 in Fig. 5 ist am oberen Ende des Gewindes eine Mutter 46 aufgeschraubt, die die Ankerplatte 28 in Anlage an dem Verformungskörper 10 hält.The Fig. 5 shows an alternative embodiment Fig. 4 in which in the superstructure 1, a vertical bore 42 is introduced. This vertical bore 42 serves to receive a dowel 43 whose upper side 39 of the adjacent section is designed as a sleeve 44 and which is held at its further inner section with radially outwardly directed deformations 45 in the superstructure 1. As already too Fig. 4 described, located at the top 39 of the superstructure 1, the bearing plate 22 which surrounds the armature shaft 40 sealingly, and above the sealing layer extends 21. On the sealing layer 21 is the floating bearing 20, which is loaded by the clamping element 23 against the sealing layer 21 , The deformation body 10 corresponds to the shape and consistency of that Fig. 4 , In the armature shaft 40 in Fig. 5 at the upper end of the thread, a nut 46 is screwed, which holds the anchor plate 28 in abutment against the deformation body 10.
