Description

Die Erfindung betrifft eine Verbindungsanordnung zwischen einzelnen Teilen eines bewehrten Rammpfahles, bestehend aus an den Stirnseiten der Rammpfahlteile zumindest an deren Eckbereichen anzuordnenden, schwalbenschwanzförmig hinterschnittene Nuten aufweisenden Verbindungsbeschlägen und aus in zwei spiegelbildlich angeordnete Verbindungsbeschläge zweier aufeinanderfolgender Rammpfahlteile einschlagbaren, annähernd doppelschwalbenschwanzförmig ausgeführten Verbindungskörpern.The invention relates to a connection arrangement between individual parts of a reinforced ram pile, consisting of connection fittings to be arranged on the end faces of the ram pile parts, at least at their corner areas, with dovetail-shaped undercut grooves, and of connecting dowel tails which can be driven into two mirror-image-arranged connection fittings of two successive ram pile parts.

Es sind bereits verschiedene Ausführungen von Verbindungsanordnungen bekannt geworden, bei denen jedoch stets enge Herstellungstoleranzen sowohl für die Verbindungsbeschläge als auch für die Verbindungskörper gegeben waren.Various designs of connection arrangements have already become known, in which, however, there were always close manufacturing tolerances both for the connection fittings and for the connection bodies.

Bei einer bekannten Anordnung (EP-A-12254) ragen bogenförmige Abschnitte der Bewehrung in Einbuchtungen an den Stirnseiten der Rammpfahlteile hinein, wobei ein U-förmiger Bügel als Verbindungskörper eingesetzt ist. Es bedarf hier einer sehr genauen Festlegung der Armierungsteile und auch einer sehr genauen Ausbildung der U-förmigen Verbindungsbügel, um eine ausreichende Spannkraft beim Einsetzen des Bügels zu erzielen.In a known arrangement (EP-A-12254), arc-shaped sections of the reinforcement protrude into indentations on the end faces of the ram pile parts, a U-shaped bracket being used as the connecting body. It requires a very precise definition of the reinforcement parts and also a very precise design of the U-shaped connecting bracket in order to achieve a sufficient clamping force when inserting the bracket.

Bei einer anderen bekannten Pfahlverbindung (DE-B-2424245) werden in schwalbenschwanzförmige Nuten Verbindungskörper eingesetzt, welche dann annähernd doppelschwalbenschwanzförmig ausgeführt sind. Diese Doppelschwalbenschwanzform ergibt sich durch das Aneinanderstoßen der Pfahlteile, so daß jeweils zwei Verbindungsbeschläge praktisch spiegelbildlich einander zugeordnet sind. Diese Nuten sind nach innen keilförmig verengt, wobei auch der Verbindungskörper keilförmig ausgebildet ist. Nach dem Einschlagen dieses keilförmigen Verbindungskörpers kann eine Lippe umgebogen werden, um ein Herausgleiten des keilförmigen Verbindungskörpers zu verhindern. Je nach dem, ob nun die Nut exakt in den Toleranzgrenzen gefertigt ist oder auch der Verbindungskörper, kann der Verbindungskörper mehr oder weniger weit in die Nut eingeschlagen werden, so daß die umschlagbare Lippe wohl ein Herausgleiten des Verbindungskörpers verhindert, nicht aber ein Festlegen desselben ermöglicht. Die Verbindung wird dann wohl in jedem Fall aufrecht erhalten, doch kann es zu gegenseitigen Bewegungen der Enden der Pfahlteile kommen, was schlußendlich auch zu einer Beschädigung der Beschlagteile führen kann.In another known pile connection (DE-B-2424245), connecting bodies are used in dovetail-shaped grooves, which are then approximately double-dovetail-shaped. This double dovetail shape results from the abutting of the pile parts, so that two connecting fittings are assigned to each other practically in mirror image. These grooves are narrowed in a wedge shape, the connecting body also being wedge-shaped. After driving in this wedge-shaped connecting body, a lip can be bent over to prevent the wedge-shaped connecting body from sliding out. Depending on whether the groove is made exactly within the tolerance limits or also the connecting body, the connecting body can be driven more or less far into the groove, so that the foldable lip prevents the connecting body from sliding out, but does not allow it to be fixed . The connection will then be maintained in any case, but there may be mutual movement of the ends of the pile parts, which may ultimately lead to damage to the fitting parts.

Die Erfindung hat sich zur Aufgabe gestellt, eine Verbindungsanordnung der eingangs genannten Art zu schaffen, bei welcher unabhängig von Fertigungstoleranzen eine exakte, feste Verbindung zwischen den Rammpfahlteilen erreicht werden kann.The invention has for its object to provide a connection arrangement of the type mentioned, in which an exact, firm connection between the ram pile parts can be achieved regardless of manufacturing tolerances.

Erfindungsgemäß gelingt dies dadurch, daß die schwalbenschwanzförmigen Nuten in den Verbindungsbeschlägen in Einschlagrichtung des Verbindungskörpers gesehen keilförmig erweitert ausgebildet sind und der Verbindungskörper korrespondierend dazu verlaufende Außenflächen aufweist, und daß der Verbindungskörper entlang einer. Längsvertikalebene in zwei Keilkörper getrennt ist, welche in entgegengesetzten Richtungen keilförmig verjüngt ausgebildet und in ihrer Endlage verriegelbar sind.This is achieved according to the invention in that the dovetail-shaped grooves in the connecting fittings are widened in a wedge shape as seen in the direction of impact of the connecting body and the connecting body has corresponding outer surfaces and that the connecting body runs along a. Longitudinal vertical plane is separated into two wedge bodies, which are tapered in opposite directions and can be locked in their end position.

Unabhängig von eventuellen Fertigungstoleranzen kann eine solcher Verbindungskörper eine ordnungsgemäß feste Verbindung zwischen aufeinanderfolgenden Rammpfahlteilen bewerkstelligen. Nach dem Einsetzen eines der beiden Keilkörper kann der zweite Keilkörper von außen eingeschlagen werden, so daß sich die beiden Keilkörper gegeneinander und an den Begrenzungsflächen der schwalbenschwanzförmigen Nut anpressen. Nach dem endgültigen Einschlagen dieser Keilkörper und einem Verriegeln derselben ist ein Lösen nicht mehr möglich, da sich die Nuten an ihren innenliegenden Enden ja erweitern, so daß ein Herausgleiten des gesamten Verbindungskörpers nicht möglicht ist. Auch durch Erschütterungen kann sich eine solche Verbindungsanordnung nicht lösen.Irrespective of any manufacturing tolerances, such a connecting body can achieve a properly firm connection between successive ram pile parts. After inserting one of the two wedge bodies, the second wedge body can be driven in from the outside, so that the two wedge bodies press against one another and against the boundary surfaces of the dovetail-shaped groove. After these wedge bodies have been finally driven in and locked, loosening is no longer possible, since the grooves widen at their inner ends, so that the entire connecting body cannot slide out. Such a connection arrangement cannot be released even by vibrations.

Die erfindungsgemäße Verbindungsanordnung ist gerade bei dem sehr rauhen Baustellenbetrieb besonders günstig einzusetzen, da durch entsprechend starkes Einschlagen sogar noch eine Verbesserung der Haltekraft erreicht wird.The connection arrangement according to the invention can be used particularly inexpensively, especially in the very rough construction site operation, since an improvement in the holding force is even achieved by correspondingly strong driving.

Weitere erfindungsgemäße Merkmale und besondere Vorteile werden in der nachstehenden Beschreibung anhand der Zeichnungen noch näher erläutert. Es zeigen : Fig. 1 eine mit Verbindungsbeschlägen ausgestattete Abdeckkappe für einen Rammpfahlteil in der Ansicht von unten, also von der Pfahlseite her gesehen, teilweise geschnitten dargestellt; Fig. 2 einen Schnitt nach der Linie I-I in Fig. 1 ; Fig. 3 einen Schnitt nach der Linie 11-11 in Fig. 1 ; Fig. 4 eine Frontansicht zweier Verbindungsbeschläge zweier aneinanderstoßender Rammpfahlteile ; Fig. 5 eine Draufsicht auf einen Verbindungskörper, teilweise aufgeschnitten dargestellt ; Fig. 6 eine Seitenansicht in Pfeilrichtung 111 gemäß Fig. 5 gesehen ; Fig. 7 einen Schnitt nach der Linie IV-IV in Fig. 5.Further features according to the invention and special advantages are explained in more detail in the following description with reference to the drawings. 1 shows a cover cap equipped with connecting fittings for a ram pile part in a view from below, that is to say seen from the pile side, partly in section; Fig. 2 is a section along the line I-I in Fig. 1; 3 shows a section along the line 11-11 in Fig. 1. 4 shows a front view of two connecting fittings of two abutting ram pile parts; Figure 5 is a plan view of a connecting body, shown partially cut away. FIG. 6 shows a side view in the direction of arrow 111 according to FIG. 5; 7 shows a section along the line IV-IV in FIG. 5.

Die Verbindungsanordnung besteht im wesentlichen aus Beschlagteilen 1, die an den Stirnseiten der Rammpfahlteile zumindest an deren Eckbereichen angeordnet sind sowie aus Verbindungskörpern 2. Beim gezeigten Beispiel sind die Verbindungsbeschläge 1 an den Ecken einer kappenartigen Abdeckung 3 für die Pfahlenden integriert. Es wäre auch möglich, diese Verbindungsbeschläge 1 über Stege miteinander zu verbinden oder aber auch einfach einzeln in den Ecken im Bereich der Stirnseiten der Rammpfahlteile einzubetten.The connection arrangement essentially consists of fitting parts 1, which are arranged on the end faces of the ram pile parts at least at their corner regions, and of connecting bodies 2. In the example shown, the connecting fittings 1 are integrated at the corners of a cap-like cover 3 for the pile ends. It would also be possible to connect these connecting fittings 1 to one another via webs, or else simply to embed them individually in the corners in the region of the end faces of the ram pile parts.

Im Bereich der Verbindungsbeschläge sind Zugelemente 4 befestigt, die in den Beton des Rammpfahlteiles hineinragen. Über eine Gewindeverbindung 5 werden die Zugelemente 4 mit den Verbindungsbeschlägen 1 bzw. der kappenförmigen Abdeckung 3 fest verbunden.In the area of the connecting fittings, tension elements 4 are fastened, which protrude into the concrete of the ram pile part. About a Ge wind connection 5, the tension elements 4 are firmly connected to the connection fittings 1 or the cap-shaped cover 3.

Die Verbindungsbeschläge weisen eine schwalbenschwanzförmig hinterschnittene Nut 6 auf, so daß sich bei Aneinanderreihen von Rammpfahlteilen durch spiegelbildlich aufeinanderfolgende Verbindungsbeschläge 1 doppelschwalbenschwanzförmige Öffnungen ergeben, wie dies der Fig. 4 entnommen werden kann. Der Verbindungskörper 2 ist deshalb ebenfalls doppelschwalbenschwanzförmig ausgeführt und wird zur Verbindung von aufeinanderfolgenden Rammpfahlteilen in die von den Nuten 6 gebildete Öffnung eingeführt.The connecting fittings have a dovetail-shaped undercut groove 6, so that double rows of dovetail-shaped openings result when rows of ram pile parts are juxtaposed by mirror-inverted connecting fittings 1, as can be seen in FIG. 4. The connecting body 2 is therefore also designed in the form of a double dovetail and is inserted into the opening formed by the grooves 6 in order to connect successive ram pile parts.

Die schwalbenschwanzförmigen Nuten 6 in den Verbindungsbeschlägen 1 sind in Einschlagrichtung des Verbindungskörpers 2 gesehen keilförmig erweitert ausgebildet. Die Nut 6 wird also im inneren Bereich des Verbindungsbeschlages weiter.The dovetail-shaped grooves 6 in the connecting fittings 1 are widened in a wedge shape as seen in the direction of impact of the connecting body 2. The groove 6 thus continues in the inner area of the connecting fitting.

Um eine ordnungsgemäße Verbindung zu erreichen, ist dann eine Zweiteilung des Verbindungskörpers 2 erforderlich, da dieser ja mit korrespondierend zu den Außenbegrenzungen der Nut 6 verlaufenden Außenflächen versehen sein muß. Der Verbindungskörper 2 ist daher entlang einer Längsvertikalebene in zwei Keilkörper 7 und 8 getrennt, welche in entgegengesetzten Richtungen keilförmig verjüngt ausgebildet sind. Dadurch ist es möglich, diese beiden Keilkörper 7 und 8 aufeinanderfolgend in die Nuten 6 einzubringen und entsprechend zu verspannen.In order to achieve a proper connection, a division of the connecting body 2 is then necessary, since this must be provided with outer surfaces corresponding to the outer boundaries of the groove 6. The connecting body 2 is therefore separated along a longitudinal vertical plane into two wedge bodies 7 and 8, which are tapered in opposite directions. This makes it possible to successively introduce these two wedge bodies 7 and 8 into the grooves 6 and to brace them accordingly.

Dabei ist es von besonderer Bedeutung, daß durch den zweiten einzusetzenden Keilkörper die erforderliche Verspannung und der Anzug des Keilkörpers erreicht wird. Es ist daher der Keilwinkel a des ersten Keilkörpers 7 größer als der Keilwinkel β der Nut 6. Ferner ist der Keilwinkel y des zweiten Keilkörpers 8 kleiner als der Keilwinkel β der Nut 6 im Verbindungsbeschlag 1. Zweckmäßigerweise wird der Keilwinkel a des ersten Keilkörpers 7 nur geringfügig größer sein als der Keilwinkel β der Nut 6 im Verbindungsbeschlag 1, so daß sich für die Ausbildung des Keilkörpers 8 und somit auch für das Einschlagen desselben ein relativ flacher Winkel ergibt. Es kann dadurch das Anzugsmoment beim Einschlagen des zweiten Keilkörpers 8 wesentlich verbessert werden.It is particularly important that the required tension and the tightening of the wedge body is achieved by the second wedge body to be used. The wedge angle a of the first wedge body 7 is therefore greater than the wedge angle β of the groove 6. Furthermore, the wedge angle y of the second wedge body 8 is smaller than the wedge angle β of the groove 6 in the connecting fitting 1. The wedge angle a of the first wedge body 7 is expediently only be slightly larger than the wedge angle β of the groove 6 in the connecting fitting 1, so that there is a relatively flat angle for the formation of the wedge body 8 and thus also for the turning of the same. The tightening torque when driving in the second wedge body 8 can thereby be significantly improved.

Der erste Keilkörper 7 mit dem größeren Keilwinkel α wird also mit dem dickeren Ende voran in die Nut 6 im Verbindungsbeschlag 1 eingesetzt, wobei dadurch in den zwischen dem ersten Keilkörper 7 und der gegenüberliegenden Nutbegrenzungsfläche verbleibenden Raum der zweite Keilkörper 8 mit dem schmaleren Ende voran eingetrieben werden kann. Es wird dadurch ein rasches und sicheres Festlegen des gesamten Verbindungskörpers 2 erreicht.The first wedge body 7 with the larger wedge angle α is thus inserted with the thicker end first into the groove 6 in the connecting fitting 1, whereby the second wedge body 8 with the narrower end is driven into the space remaining between the first wedge body 7 and the opposite groove boundary surface can be. A quick and secure fixing of the entire connecting body 2 is thereby achieved.

Besonders wesentlich ist noch, daß die Keilkörper 7 und 8 in ihrer Endlage verriegelbar sind. Dies kann natürlich durch irgendwelche umbiegbare Laschen od. dgl. erfolgen. Besonders vorteilhaft ist es jedoch, wenn diese gegenseitige Fixierung allein zwischen den beiden Keilkörpern 7 und 8 erfolgt, wie dies beim gezeigten Beispiel dargestellt ist. Der erste Keilkörper 7 weist hier an seinem äußeren, schmaleren Ende eine Lasche 9, einen Fortsatz od. dgl. auf, welche bzw. welcher in Richtung zum zweiten Keilkörper 8 umschlagbar ist. Durch dieses Umschlagen wird . nicht nur eine Fixierung erreicht, sondern infolge der Schlagbewegung in Pfeilrichtung 10 wird der Keilkörper 8 zusätzlich noch weiter in die Nut 6 eingeschlagen, ohne daß dabei der Keilkörper 7 herausgezogen werden könnte. Nach dem Umschlagen der Lasche 9 wird eine Fixierung des gesamten Verbindungskörpers 2 erreicht, die praktisch nicht lösbar ist, zumindest aber durch Erschütterungen od. dgl. keinesfalls gelockert werden kann. Durch das Umbiegen der Lasche 9 wird wieder ein in sich kompakter Gesamtverbindungskörper 2 geschaffen, welcher ja durch die Erweiterung im Innern des Verbindungsbeschlages nicht aus dieser Stellung herausführen kann. Derjenige Keilkörper 8, welcher an sich herausgleiten könnte, ist jedoch durch diese umgebogene Lasche 9 entsprechend fixiert.It is also particularly important that the wedge bodies 7 and 8 can be locked in their end position. This can of course be done by any bendable tabs or the like. However, it is particularly advantageous if this mutual fixation takes place solely between the two wedge bodies 7 and 8, as is shown in the example shown. The first wedge body 7 here has at its outer, narrower end a tab 9, an extension or the like, which can be turned over in the direction of the second wedge body 8. By turning this over. not only a fixation is achieved, but as a result of the striking movement in the direction of arrow 10, the wedge body 8 is additionally driven into the groove 6 without the wedge body 7 being able to be pulled out. After the flap 9 has been turned over, the entire connecting body 2 is fixed, which is practically impossible to solve, but at least cannot be loosened by vibrations or the like. By bending the tab 9, a compact overall connecting body 2 is again created, which cannot extend out of this position due to the expansion inside the connecting fitting. The wedge body 8, which could slide out itself, is however fixed accordingly by this bent tab 9.

Damit durch unscharfe Kanten in den Nuten 6 keine Behinderung auftritt, ist zweckmäßigerweise an den doppeischwalbenschwanzförmigen Außenflächen der beiden Keilkörper 7 und 8 am Übergang der beiden Schrägflächen eine Nut 11 herausgearbeitet.In order that no obstruction occurs due to blurred edges in the grooves 6, a groove 11 is expediently worked out on the double-swallowtail-shaped outer surfaces of the two wedge bodies 7 and 8 at the transition of the two inclined surfaces.

Durch die erfindungsgemäßen Maßnahmen wird eine konstruktiv einfache, aber sicher wirkende Verbindung für Rammpfahlteile geschaffen.The measures according to the invention create a structurally simple but safe-acting connection for ram pile parts.

In den Eckbereichen der Abdeckung 3, also im Bereich der Verbindungsbeschläge 1, ist eine schräg abfallende Abschlußwand 15 vorgesehen (Fig. 3), die einen Druck auf den anschließenden Beton ausüben kann (bei Belastung und auch beim Einschlagen der Rammpfahlteile). Es ist durch die schräg abfallende Abschlußwand 15 stets ein Druck Richtung Pfahlzentrum gegeben, so daß keine Betonteile ausbrechen können, wie dies z. B. bei ebener Abschlußwand und bei Anordnung von Versteifungsrippen usw. der Fall ist.In the corner areas of the cover 3, that is to say in the area of the connecting fittings 1, an obliquely sloping end wall 15 is provided (FIG. 3), which can exert pressure on the subsequent concrete (under load and also when the ram pile parts are driven in). There is always a pressure towards the pile center through the sloping end wall 15, so that no concrete parts can break out, as z. B. with a flat end wall and with the arrangement of stiffening ribs, etc. the case.
