Description

Technisches GebietTechnical area

Die Erfindung betrifft eine Anordnung zur Befestigung von Pfosten für Schutzwände auf Bauwerken oder Fundamenten.The invention relates to an arrangement for fixing posts for protective walls on structures or foundations.

Stand der TechnikState of the art

Beim Bau von Schutzwänden beispielsweise Lärmschutz-, Windschutz-, Blendschutz-, Schallschutzwänden oder dgl. werden auf Bauwerken oder Fundamenten in der Regel Einbauelemente einbetoniert oder nach Betonage der Bauwerke bzw. Fundamente Gewindestäbe durchgeankert oder auch eingeklebt. Die Schutzwände sind je nach Umgebungsbedingungen teilweise hohen Belastungen ausgesetzt, wobei nicht nur Wind und Sturm erhebliche Kräfte auf die Wandelemente und die Pfosten, an denen diese aufgenommen sind, ausüben. Durch vorbeifahrende Züge oder Kraftfahrzeuge, insbesondere des Güterverkehrs werden hohe dynamische Lasten in Form von Druck- und Sogwirkung über die Wand in die Einbauelemente und somit in die Bauwerke bzw. Fundamente eingeleitet. So haben z. B. Untersuchungen an Hochgeschwindigkeitsstrecken der Deutschen Bahn gezeigt, dass es hier zu einer hochgradigen dynamischen Belastung kommt, die großen Einfluss auf die Dauerhaftigkeit des Bauwerkes hat. Eine Schiefstellung der Verankerungselemente wirkt sich auf die Dauerhaftigkeit der Verbindung in erheblichem Maße negativ aus. Da die Einbringung der Einbauelemente ein handwerklicher Vorgang ist und daher hinsichtlich der Genauigkeiten den Bedingungen der Baustelle unterworfen ist, kann eine ausreichende Reduzierung der Schiefstellung der Einbauelemente bei der Montage nicht sichergestellt werden. In der Offenlegungsschrift DE 20 2007 002 395 U1 ist die Befestigung eines Pfostens auf einem Betonbauteil mittels einer Schraubverbindung beschrieben. Zwischen Fußplatte des Pfostens und der Mutter bzw. Schraube ist eine Keilsicherungsscheibe als Zwischenlage angeordnet, die Verschraubung ist mit Vorspannung angezogen. Damit können Montageungenauigkeiten jedoch nicht geeignet eliminiert werden, auch die Vorspannung der Verschraubung ist nicht für extreme dynamische Einwirkungen geeignet. Dies ist für die extremen dynamischen Beanspruchungen im Bereich der Hochgeschwindigkeitsstrecken der Bahn noch verbesserungsfähig, um eine noch größere Dauerhaftigkeit der Bauwerke zu gewährleisten.In the construction of protective walls, for example, noise protection, wind protection, anti-glare, sound insulation walls or the like. Embedded concrete elements or concreted by concrete constructions of the structures or foundations threaded rods or glued on buildings or foundations in the rule. Depending on the environmental conditions, the protective walls are sometimes subjected to high loads, with not only wind and storm exerting considerable forces on the wall elements and the posts on which they are accommodated. By passing trains or motor vehicles, especially goods traffic high dynamic loads in the form of pressure and suction effect on the wall in the mounting elements and thus in the structures or foundations are initiated. So z. B. Investigations on high-speed lines of Deutsche Bahn shown that there is a high-grade dynamic load, which has a major impact on the durability of the building. An inclination of the anchoring elements has a significant negative effect on the durability of the connection. Since the introduction of the installation elements is a manual process and therefore subject to the conditions of the construction site in terms of accuracy, can a sufficient Reduction of the misalignment of the mounting elements during assembly can not be ensured. In the published patent application DE 20 2007 002 395 U1 the attachment of a post on a concrete component by means of a screw connection is described. Between the foot plate of the post and the nut or screw a wedge lock washer is arranged as an intermediate layer, the screw is tightened with bias. This assembly inaccuracies, however, can not be properly eliminated, even the bias of the screw is not suitable for extreme dynamic effects. This can still be improved for the extreme dynamic stresses in the area of the high-speed rail lines in order to ensure even greater durability of the structures.

Das Dokument DE4330765A1 offenbart die Merkmale des Oberbegriffs des Anspruchs 1. Aufgabe der Erfindung
Aufgabe der Erfindung ist es, für den Fall der extrem hohen Anforderungen der Hochgeschwindigkeitsstrecken eine Anordnung zur Befestigung von Pfosten zu schaffen, durch welche die negativen Einflüsse der Schiefstellung von Einbauelementen und auch der starken Wechselspannungen in den Befestigungselementen infolge der hochgradig dynamischen Einwirkungen auf die Dauerhaftigkeit ausgeschlossen oder zumindest reduziert werden.
Darstellung der Erfindung
Diese Aufgabe wird durch eine Anordnung zur Befestigung von Pfosten für Schutzwände mit den Merkmalen des Anspruchs 1 gelöst.
Der negative Einfluss der Schiefstellung der Einbauelemente auf die Dauerhaftigkeit der Befestigung ist auf die Tatsache zurückzuführen, dass durch die schief gestellten Gewindebolzen eine exzentrische Lasteinleitung entsteht, welche als Biegebeanspruchung auf die Gewindebolzen wirkt und damit eine zusätzliche Belastung darstellt. Die Ausgleichsvorrichtung, die erfindungsgemäß eine Kegelpfanne und eine Kugelscheibe umfasst, ermöglicht es, Schiefstellungen der Gewindebolzen an den Einbauelementen auszugleichen und damit die Last zentrisch, d.h. in Richtung der Längsachse des Gewindebolzens einzuleiten. In der Regel können Winkelabweichungen bis zu 3° ausgeglichen werden. Darüber hinaus entsteht durch die wiederkehrende hohe dynamische Belastung auf das Befestigungsdetail eine Wechselwirkung zwischen Be- und Entlastung, die häufig mit einem Vorzeichenwechsel der Spannungen im Verankerungselement einher geht. Durch Aufbringen einer definierten Vorspannung auf die Verankerung kann die Verformung der Verbindung - und damit eine zusätzliche Abweichung des Pfostens aus der Solllage mit den zugehörigen Effekten - und die Spannungssituation im Element verändert werden, so dass hinsichtlich der Betriebsfestigkeit und damit der Dauerhaftigkeit der Verankerungsverbindung eine deutliche Verbesserung erzielt wird. Zur Sicherstellung des erforderlichen Vorspannniveaus der Verbindung werden bei der Bemessung relevante Einflussfaktoren über den Zeitraum der Nutzung berücksichtigt und die Vorspannkraft entsprechend berechnet und an der Schraubverbindung festgelegt. Dennoch besteht zusätzlich über die gesamte Nutzungsdauer die Möglichkeit, die Anordnung nachzuspannen.
Zur Realisierung der Vorspannung ist eine freie Länge des Verankerungsstabes erforderlich, in der diesem eine unbehinderte Vordehnung aufgezwungen werden kann. Hierfür wird erfindungsgemäß oberhalb der Einbindung in den Beton des Bauwerkes der Verankerungsstab mit einem Werkstoff umgeben, der den Kraftschluss zwischen dem Verankerungsstab und dem Vergussmaterial, das zwischen Fußplatte und Bauwerksbeton eingebaut ist, verhindert. In der Fußplatte ist dies geometrisch durch eine entsprechende Größe der Durchbohrungen / Löcher in der Platte sichergestellt.
In einer Variante der Erfindung - der durchgängigen Durchankerung des Betonbauwerkes, bei der keine Krafteinleitung über eine Verankerungslänge in das Bauwerk durch Verbund zwischen Verankerungsstab und Beton erforderlich ist - kann die freie Dehnlänge im Bauteil liegen. Hier ist der Einbau eines Hüllrohres, das mit geeignetem Material verfüllt ist, eine Alternative zur reinen Ummantelung des Verankerungsstabes.
Der Ummantelungswerkstoff muss ausrreichend dehnfähig sein, um die Längenänderung des Verankerungselementes im Zuge der Vorspannung nicht zu behindern. Es hat sich gezeigt, dass bestimmte Bitumensorten sehr geeignet sind. Vorgespannte Verbindungen bedürfen eines besonderen Augenmerkes hinsichtlich des Korrosionsschutzes. Somit ergibt sich an den Ummantelungswerkstoff eine weitere Anforderung: er muss den Korrosionsschutz sicherstellen. In der Regel sind die Verankerungselemente verzinkt / vorbehandelt, so dass es zu keiner Materialunverträglichkeit zwischen Legierung und Ummantelungswerkstoff kommen darf. Auch eine Beständigkeit gegenüber dem umgebenden Werkstoff Mörtel und dessen alkalischen Eigenschaften ist notwendig. Weiter ist eine hohe Diffusionsdichtigkeit gefordert, die auch den dynamischen Beanspruchungen (Vibrationen) standhält. Hierfür sind besonders Materialien geeignet, die - wie Bitumen - zwar bei dauerhafter Krafteinwirkung kriechen, bei kurzfristiger Krafteinwirkung hingegen elastisch reagieren.
Hinsichtlich der Korrosionsthematik - vor allem der Spannungsrisskorrosion in vorgespanntem Stahl - hat es sich überraschenderweise als vorteilhaft gezeigt, den Verankerungsstab in einer geringeren Festigkeitsklasse - die mit einer geringeren Empfindlichkeit hinsichtlich der wasserstoffinduzierten Spannungsrisskorrosion einhergeht - als die Mutter auszubilden: besonders eine Werkstoffwahl mit der Werkstoff-Festigkeitskennzeichnung 8 (verzinkter Feinkornbaustahl) oder der Werkstoffnummer 1.4571 (nichtrostender Stahl) für den Gewindestab, der Werkstoffnummer 1.4571 (nichtrostender Stahl) für Kugelscheibe und Kegelpfanne und der Werkstoffkennnummer 1.4401, Festigkeitskennzeichnung 10 (verzinkter Feinkornbaustahl) für die Mutter (System HV, werkseitig geschmiert) hat sich als vorteilhaft erwiesen. Die Werkstoffkennnummern beziehen sich auf in Europa übliche Bezeichnungen, im außereuropäischen Ausland sind analoge Werkstoffe zu verwenden.The document DE4330765A1 discloses the features of the preamble of claim 1. object of the invention
The object of the invention is to provide in the case of extremely high demands of high-speed lines an arrangement for attachment of posts, by which excluded the negative influences of misalignment of mounting elements and the strong AC voltages in the fasteners due to the highly dynamic effects on the durability or at least reduced.
Presentation of the invention
This object is achieved by an arrangement for fastening posts for protective walls with the features of claim 1.
The negative influence of the misalignment of the mounting elements on the durability of the attachment is due to the fact that caused by the skewed threaded bolt an eccentric load introduction, which acts as a bending stress on the threaded bolt and thus represents an additional burden. The compensation device, which according to the invention comprises a conical socket and a spherical disk, makes it possible to compensate misalignments of the threaded bolts on the installation elements and thus to initiate the load centrally, ie in the direction of the longitudinal axis of the threaded bolt. As a rule, angle deviations of up to 3 ° can be compensated. In addition, due to the recurrent high dynamic load on the fastening detail, an interaction between loading and unloading, which is often accompanied by a change of sign of the stresses in the anchoring element. By applying a defined preload to the anchorage can the deformation of the compound - and thus an additional deviation of the post from the desired position with the associated effects - and the voltage situation in the element are changed, so that in terms of durability and thus the durability of the anchoring connection a significant improvement is achieved. To ensure the required preload level of the connection, the relevant influencing factors over the period of use are taken into account in the design and the preload force is calculated accordingly and determined at the screw connection. Nevertheless, there is also the option of restoring the arrangement over the entire service life.
To realize the bias, a free length of the anchoring rod is required, in which an unrestricted pre-strain can be imposed. For this purpose, according to the invention surrounded above the involvement in the concrete of the structure of the anchoring rod with a material that prevents the frictional connection between the anchoring rod and the potting material that is installed between the base plate and structural concrete. In the footplate, this is geometrically ensured by a corresponding size of the holes / holes in the plate.
In a variant of the invention - the continuous anchoring of the concrete structure, in which no force is required over an anchoring length in the building by bonding between anchoring rod and concrete - can be the free stretch length in the component. Here is the installation of a cladding tube, which is filled with suitable material, an alternative to the pure sheathing of the anchoring rod.
The sheathing material must be sufficiently extensible so as not to hinder the change in length of the anchoring element in the course of the prestressing. It has been shown that certain types of bitumen are very suitable. Prestressed connections require special attention with regard to corrosion protection. This results in a further requirement for the cladding material: it must ensure corrosion protection. As a rule, the anchoring elements are galvanized / pretreated, so that there must be no material incompatibility between the alloy and the cladding material. Also, a resistance to the surrounding material mortar and its alkaline properties is necessary. Furthermore, a high degree of diffusion-tightness is required, which also withstands the dynamic stresses (vibrations). For this purpose, especially materials are suitable, which - like Bitumen - while creeping with constant force, react elastically with short-term force.
With regard to the corrosion issue - especially the stress corrosion cracking in toughened steel - it has surprisingly been found advantageous to design the anchoring rod in a lower strength class - which is associated with a lower sensitivity with respect to hydrogen-induced stress corrosion cracking than the mother: in particular a choice of material with the material Strength marking 8 (galvanized fine grain steel) or material number 1.4571 (stainless steel) for the threaded rod, material number 1.4571 (stainless steel) for spherical disc and conical socket and material number 1.4401, strength marking 10 (galvanized fine grain structural steel) for the nut (HV system, factory lubricated) has proven to be advantageous. The material identification numbers refer to common names in Europe, while analogous materials are to be used in non-European countries.

Gemäß einer Ausgestaltung der Erfindung umfasst das Einbauelement mindestens vier Anker, die mittels Querverbindungsstäben zu einer Baueinheit zusammengesetzt sind. Dadurch braucht vor dem Gießen des Betons des Bauwerkes oder Fundamentes lediglich ein Einbauelement positioniert zu werden, an dem alle für die Befestigung des Pfostens erforderlichen Gewindeabschnitte ausgebildet sind. Alternativ dazu ist es auch möglich, dass mehrere - mindestens vier - Einbauelemente, die lediglich jeweils einzelne Anker umfassen, vorgesehen sind. Eine solche Anordnung ist dann zu bevorzugen, wenn die Einbauelemente durch Verkleben im Betonkörper befestigt oder durch vollständiges Durchankern des Betonkörpers verankert werden sollen.According to one embodiment of the invention, the mounting element comprises at least four anchors, which are assembled by means of cross connection bars to form a structural unit. As a result, only one installation element needs to be positioned before casting the concrete of the structure or foundation, on which all threaded sections required for the attachment of the post are formed. Alternatively, it is also possible that a plurality of - at least four - installation elements, which only each comprise individual anchors, are provided. Such an arrangement is to be preferred if the installation elements are to be fastened by gluing in the concrete body or anchored by complete anchoring of the concrete body.

Um die Einbauelemente besonders gut mit dem Beton zu verbinden, ist es vorteilhaft, dass die Anker einen Abschnitt aus einem Rippenstahl - hier hat sich der übliche Baustahl Bst 500S als ausreichend erwiesen - aufweisen. Der Gewindeabschnitt zum Aufschrauben der Befestigungsmutter ist in der Regel am Anker angeformt und somit einstückig mit diesem ausgeführt. Alternativ dazu ist es jedoch auch möglich, dass der Gewindeabschnitt durch einen Gewindebolzen gebildet ist, der in eine Gewindebohrung eines am Anker ausgebildeten Hülsenabschnitts eingeschraubt ist.In order to connect the installation elements particularly well with the concrete, it is advantageous that the anchor has a section of a ribbed steel - here, the usual structural steel Bst 500S has been found to be sufficient. The threaded portion for screwing the fastening nut is usually formed on the anchor and thus designed in one piece with this. Alternatively, however, it is also possible that the threaded portion is formed by a threaded bolt which is screwed into a threaded bore of an armature formed on the sleeve portion.

Zur Ausrichtung der Fußplatte dahingehend, dass der Pfosten in der Solllage - meistens der Vertikalen - ausgerichtet ist, wird vorgeschlagen, dass zwischen der Fußplatte und dem Betonkörper ein Abstandselement angeordnet ist, das sich vorzugsweise in einem Flächenschwerpunkt der Fußplatte befindet. Der Raum zwischen Fußplatte und Betonkörper um dieses Abstandselement herum wird mit einer Schicht aus einem schwindarmen Mörtel oder einer anderen geeigneten Vergussmasse gefüllt.To align the footplate to the effect that the post is oriented in the desired position, usually the vertical, it is proposed that a spacing element be arranged between the footplate and the concrete body, which is preferably located in a centroid of the footplate. The space between the foot plate and concrete body around this spacer is filled with a layer of low-shrink mortar or other suitable potting compound.

Überraschenderweise zeigte sich, dass ohne zusätzliche Bitumenbeschichtung der Korrosionsschutz durch ansonsten bewährte Verzinkung unter diesen Randbedingungen (fehlende Belüftung, Vorspannung) nicht ausreicht.In the Fig. 1 to 3 is a section of a concrete structure 1 - for example, the cap area of a bridge - shown. The prefabricated installation element is preferably embedded in the concrete body 1 or durchge anchored, but it is also possible to attach this by gluing. On the concrete body 1 is a post 3, which is preferably made of steel and is provided with a foot plate 4, which serves to be fastened to the mounting element. On this attachment will be discussed in more detail below. At the post 3, the protective walls are attached.
Fig. 1 shows a built-in at least four anchors 5 built-in part, each anchor 5 a concrete to be anchored portion 6, for example a ribbed steel (BSt 500S) and a threaded portion of stainless steel 7 includes. The anchors 5 are arranged substantially parallel and joined together via steel connecting rods 2 to form a structural unit with a defined spatial configuration, in particular welded together. The installation element shown is poured in the course of building construction in the concrete body 1, with the post mounting galvanized threaded bolt 8 or threaded bolt made of stainless steel 8 'are screwed into the threaded portion of stainless steel 7. Alternatively, threaded bolts 8 'can already be welded to the installation element in advance. The galvanized threaded bolt 8 is above the Bauwerksbetons 1 - in the mortar layer 13, the foot plate 4 and the conical-spherical disk system 9, 10 - provided with a Bitumendickbeschichtung 15 to ensure the free preload length and corrosion protection. Surprisingly, it was found that without additional bituminous coating, the corrosion protection by otherwise proven galvanizing under these boundary conditions (lack of ventilation, preload) is insufficient.

In Fig. 2 ist ein Schnitt durch eine in einem Betonkörper 1 gehaltene Vorrichtung mit einem daran befestigten Pfosten 3 gezeigt. Dabei sind mehrere einzelne Einbauelemente 5 im Betonkörper 1 verankert, beispielsweise durch Verklebung befestigt. In der Schnittdarstellung sind lediglich zwei der mindestens vier Einbauelemente 5 zu sehen. Jeder Anker 5 besteht aus einem längeren Abschnitt aus Betonstahl BSt 500S 6 zur Verankerung im Betonkörper 1 und einem Gewindeabschnitt aus Edelstahl 8', der aus dem Betonkörper 1 herausragt. Im Bereich des Mörtelbettes 13 wird eine Bitumendickbeschichtung 15 angebracht, die den kraftschlüssigen Verbund zwischen Gewinde 8' und Mörtelbett 13 verhindert. Der Gewindebolzen 8' aus Edelstahl bedarf keines weiteren Korrosionsschutzes - so dass auf die Bitumendickbeschichtung 15 im Bereich der Fußplatte 4 und des Kegelpfannen-Kugelscheiben-Systems 9, 10 verzichtet werden kann.In Fig. 2 is a section through a held in a concrete body 1 device with an attached post 3 shown. Several individual mounting elements 5 are anchored in the concrete body 1, for example, fixed by gluing. In the sectional view, only two of the at least four mounting elements 5 can be seen. Each anchor 5 consists of a longer section of reinforcing steel BSt 500S 6 for anchoring in the concrete body 1 and a threaded portion made of stainless steel 8 ', which protrudes from the concrete body 1. In the area of the mortar bed 13 a Bitumendickbeschichtung 15 is attached, which prevents the frictional bond between thread 8 'and mortar bed 13. The threaded bolt 8 'made of stainless steel requires no further corrosion protection - so that can be dispensed with the Bitumendickbeschichtung 15 in the footplate 4 and the conical-spherical-disc system 9, 10.

Fig. 3 zeigt einen Schnitt mit einer Variante, bei der der Betonkörper 1 komplett durchankert wird. In nachträglich hergestellten Bohrlöchern werden verzinkte Gewindestäbe 8, die mit einer Bitumendickbeschichtung 15 versehen sind, eingebracht und an Bauteilober- und -unterseite mit einer Anordnung von Ausgleichsvorrichtung 9, 10 und Muttern 11, 12 vorgespannt. Fig. 3 shows a section with a variant in which the concrete body 1 is completely durchankert. In subsequently produced wells galvanized threaded rods 8, which are provided with a Bitumendickbeschichtung 15, introduced and biased on Bauteilober- and -unterseite with an array of balancing device 9, 10 and nuts 11, 12.

Der Pfosten 3 in Fig. 3 besitzt wie in Fig. 1 und 2 eine Fußplatte 4, die mit Bohrungen versehen ist, durch die sich die Gewindeabschnitte 8, 8' der Anker 5 erstrecken. Unter der Fußplatte 3 befindet sich ein Abstandselement 14, beispielsweise ein Kunststoff-Distanzklotz, wobei das Abstandselement 14 mindestens annähernd im Flächenschwerpunkt der Fußplatte 4 angeordnet ist. Um das Abstandselement 14 herum ist der zwischen dem Betonkörper 1 und der Fußplatte 4 gebildete Raum mit einer Schicht aus Mörtel oder Vergussmasse 13 gefüllt.The post 3 in Fig. 3 owns as in Fig. 1 and 2 a foot plate 4 which is provided with holes through which the threaded portions 8, 8 'of the armature 5 extend. Below the foot plate 3 is a spacer element 14, for example a plastic spacer block, wherein the spacer element 14 is arranged at least approximately in the centroid of the base plate 4. Around the spacer 14 around the space formed between the concrete body 1 and the base plate 4 is filled with a layer of mortar or grout 13.

Auf die Gewindeabschnitte 8, 8' der Anker 5 sind unter Zwischenschaltung von je einer Ausgleichsvorrichtung 9, 10 verzinkte Muttern 11 aus hochfestem Stahl aufgeschraubt, mittels derer die Fußplatte 4 gegen den Betonkörper 1 bzw. die Ausgleichsschicht 13 (vor-)gespannt ist. Eine zusätzliche Sicherung gegen Lösen dieser Verbindung erfolgt mit einer Verlier-Sicherungsmutter 12 aus nichtrostendem Stahl.On the threaded portions 8, 8 'of the armature 5 are screwed with the interposition of a compensating device 9, 10 galvanized nuts 11 made of high-strength steel, by means of which the base plate 4 against the concrete body 1 and the compensation layer 13 (pre-) stretched. An additional safeguard against loosening this connection is made with a loss-locking nut 12 made of stainless steel.

Die in Fig. 1 und 2 nicht näher beschriebene Befestigung der Fußplatte 4 auf dem Betonkörper 1 erfolgt ebenso mit Muttern 11, 12 an Gewindeabschnitten 8, 8' der Anker 5 unter Zwischenschaltung von Ausgleichsvorrichtungen 9, 10, wie dies in Fig. 3 angegeben ist. Die Ausgleichsvorrichtung 9, 10, die später noch näher erläutert wird, ermöglicht es - innerhalb bestimmter Grenzen -, durch Schiefstellung bedingte Winkelabweichungen von den Längsachsen der Anker auszugleichen. Dadurch wird eine zentrische Lasteinleitung der von der beim Spannen der Mutter 11 auf dem Gewindeabschnitt 8, 8' erzeugten Spannkraft in den Anker 5 erreicht. Eine durch handwerkliche Tätigkeit auf der Baustelle bei der Fertigung des Betonbauwerks bzw. Betonkörpers 1 bedingte Winkelabweichung α ist in Fig. 5 dargestellt.In the Fig. 1 and 2 unspecified attachment of the base plate 4 on the concrete body 1 is also done with nuts 11, 12 at threaded portions 8, 8 'of the armature 5 with the interposition of balancing devices 9, 10, as in Fig. 3 is specified. The compensation device 9, 10, which will be explained in more detail later, makes it possible - within certain limits - to compensate for skewed angle deviations from the longitudinal axes of the anchor. As a result, a centric load introduction of the clamping force generated by the clamping of the nut 11 on the threaded portion 8, 8 'in the armature 5 is achieved. An angle deviation α caused by manual work on the construction site in the production of the concrete structure or concrete body 1 is in Fig. 5 shown.

Die Einbauelemente 5 bestehen vorzugsweise aus Edelstahl oder verzinktem Stahl und werden im Beton eingegossen oder verklebt bzw ggf. durchgeankert. Anschließend wird der Pfosten 3 mit seiner Fußplatte 4 aufgesetzt, so dass der Gewindeabschnitt 8, 8' jedes Ankers 5 durch entsprechende Bohrungen der Fußplatte 4 geführt wird. Im Falle der Ausführung mit Verzinkung ist der Gewindeabschnitt 8 zusätzlich mit einer Bitumendickbeschichtung 15 versehen. Zur Aufrechterhaltung eines für die Ausrichtung des Pfostens 3 erforderlichen Abstands wird unter der Fußplatte 4 das Abstandselement 14 platziert, und zwar möglichst im Flächenschwerpunkt der Fußplatte 4.The mounting elements 5 are preferably made of stainless steel or galvanized steel and are cast or glued in the concrete or possibly durchgeankert. Subsequently, the post 3 is placed with its base plate 4, so that the threaded portion 8, 8 'of each armature 5 is guided by corresponding holes in the base plate 4. In the case of the embodiment with galvanizing the threaded portion 8 is additionally provided with a Bitumendickbeschichtung 15. To maintain a required for the alignment of the post 3 distance the spacer 14 is placed under the base plate 4, if possible in the centroid of the base plate. 4

Alternativ ist das Abstandselement 14 bereits fest unterhalb der Fußplatte 4 angebracht, so dass eine zusätzliche Justierung zum Flächenschwerpunkt entfällt und auch die Gefahr eines Verrutschens des Abstandselementes 14 beim Aufstellen des Pfostens 3 nicht mehr besteht.
Der Pfosten 3 kann somit bezüglich seiner Längsachse in jede beliebige Richtung verschwenkt werden, um eine exakte Ausrichtung zur Solllage zu erreichen. Es folgt eine Zwischensicherung mit den Muttern 11. Sodann wird um das Abstandselement 14 herum der Freiraum zwischen Fußplatte 4 und dem Betonkörper 1 mit einer Vergussmasse oder Mörtel verfüllt, wodurch sich die Schicht 13 ergibt. Nach dem Aushärten der Verguss-Schicht 13 werden die Muttern 11 gelöst und der Bereich des verzinkten Gewindestabes 8 im Anschluss an die bereits bestehende Beschichtung 15 bis unter das Kegelpfannen-Kugelscheiben-Systems 9, 10 mit Bitumen beschichtet. Unter Zwischenfügung der Ausgleichsvorrichtung 9, 10 werden die hochfesten, verzinkten Muttern 11 erneut aufgeschraubt und vorgespannt. Abschließend wird zur zusätzlichen Sicherung der Verbindung die Verlier-Sicherungsmutter 12 angebracht.Alternatively, the spacer element 14 is already fixedly mounted below the base plate 4, so that an additional adjustment to the centroid and eliminates the risk of slippage of the spacer 14 during installation of the post 3 no longer exists.
The post 3 can thus be pivoted with respect to its longitudinal axis in any direction in order to achieve an exact alignment with the desired position. Then follows an intermediate securing with the nuts 11. Then, around the spacer 14 around the space between the base plate 4 and the concrete body 1 is filled with a potting compound or mortar, whereby the layer 13 results. After hardening of the potting layer 13, the nuts 11 are loosened and the area of the galvanized threaded rod 8, following the coating 15 already existing, is coated with bitumen under the conical-cup-spherical disk system 9, 10. With the interposition of the compensating device 9, 10, the high-strength, galvanized nuts 11 are screwed and prestressed again. Finally, the loss-locking nut 12 is attached to additional security of the connection.

Die Fig. 4 zeigt einen einzelnen Anker 5, der einen Abschnitt 6 aus BSt 500S zur Verankerung im Beton und einen Gewindeabschnitt 8, 8' - entweder mit Feuerverzinkung oder aus nichtrostendem Stahl - zum Aufschrauben der Muttern 11, 12 umfasst. Der Abschnitt 6 ist zumindest über einen Teil seiner Längserstreckung als Rippenstahl ausgeführt, um einen möglichst guten Formschluss mit dem Beton oder Kleber zu erreichen.The Fig. 4 shows a single anchor 5 comprising a section 6 of BSt 500S for anchoring in concrete and a threaded portion 8, 8 '- either hot dip galvanized or stainless steel - for screwing the nuts 11, 12 comprises. The section 6 is designed at least over part of its longitudinal extent as a ribbed steel in order to achieve the best possible positive connection with the concrete or adhesive.

In Fig. 5 ist die Ausgleichsvorrichtung 9, 10 im Schnitt dargestellt, wobei die Ausgleichsvorrichtung 9, 10 eine Kegelpfanne 9 und eine darauf gelagerte Kugelscheibe 10 umfasst. Diese Bauteile sind bezüglich ihrer Form in DIN 6319 festgelegt. In der Darstellung ist durch die Ausgleichsvorrichtung 9, 10 der Gewindebolzen 8 geführt, dessen Längsachse LA2 um den Winkel α geneigt zur Systemachse verläuft. Auf die mit dem Pfosten 3 in Fig. 1, 2 und 3 ausgerichtete Fußplatte 4 wird die Kegelpfanne 9 aufgelegt, deren Achse LA1 parallel zur Systemachse des Pfostens verläuft. Um die Neigung des Gewindeabschnitts 8 auszugleichen, ist die Kugelscheibe 10 auf der Kegelpfanne 9 verschwenkt, so dass die Längsachse LA2 der Kugelscheibe identisch mit der Längsachse LA1 des Gewindeabschnitts 8 des Ankers ist. Durch die verschwenkte Kugelscheibe 9 wird eine parallel zur Spannfläche der Sechskantmutter 11 verlaufende Krafteinleitungsfläche bereitgestellt, so dass die Lastaufnahme genau in Längsrichtung der Anker 5 des Einbauelementes gewährleistet ist. Der Winkel zwischen den Längsachsen LA1 und LA2 ist mit α bezeichnet.In Fig. 5 the compensation device 9, 10 is shown in section, wherein the compensation device 9, 10 comprises a conical socket 9 and a ball disc 10 mounted thereon. These components are defined with respect to their shape in DIN 6319. In the illustration, the threaded bolt 8 is guided by the compensating device 9, 10, whose longitudinal axis LA2 is inclined by the angle α to the system axis. On the with the post 3 in Fig. 1, 2 and 3 Aligned foot plate 4, the cone socket 9 is placed, whose axis LA1 runs parallel to the system axis of the post. To compensate for the inclination of the threaded portion 8, the spherical disk 10 is pivoted on the conical socket 9, so that the longitudinal axis LA2 of the spherical disk is identical to the longitudinal axis LA1 of the threaded portion 8 of the armature. Due to the pivoted-up spherical disk 9, a force introduction surface extending parallel to the clamping surface of the hexagonal nut 11 is provided, so that the load absorption is exactly in the longitudinal direction the anchor 5 of the mounting element is guaranteed. The angle between the longitudinal axes LA1 and LA2 is denoted by α.
