Description

Die Erfindung betrifft ein Überbrückungselement zum Überbrücken eines Abstandes zwischen zwei Betonleitwänden. Ferner betrifft die Erfindung ein Fahrbahnbegrenzungselement, das zwischen in einem Abstand zueinander angeordneten Betonleitwänden ein erfindungsgemäßes Überbrückungselement aufweist.The invention relates to a bridging element for bridging a distance between two concrete Leitwänden. Furthermore, the invention relates to a roadway boundary element, which has an inventive bridging element between at a distance from each other arranged concrete guide walls.

Zur Fahrbahnbegrenzung ist das Vorsehen von Betonleitwänden bekannt. Hierbei handelt es sich üblicherweise um im Querschnitt gestuft ausgebildete Betonelemente, die in Längsrichtung mit Bewehrungselementen wie Drahtseilen versehen sind. Derartige Betonleitwände sind beispielsweise in DE 101 45 647 und DE 10 2005 030 412 beschrieben. Üblicherweise werden Betonleitwände unmittelbar vor Ort aus Ortbeton hergestellt. Insbesondere bei der Anordnung von Betonleitwänden auf bereits bestehenden Fahrbahnen, aber auch bei Neubauten, besteht die Problematik, dass Schachtabdeckungen wie Gullideckel oder dergleichen nach Fertigstellung der Betonleitwand unter dieser angeordnet wären. Die Schachtabdeckungen müssen jedoch zu regelmäßigen Wartungsarbeiten und dergleichen zugänglich sein. Andererseits muss ferner gewährleistet sein, dass der durch die Betonleitwand erzielte Schutz, d.h. das Zurückhalten von Kraftfahrzeugen im Fall eines Aufpralls, auch in dem Bereich der Schachtabdeckung gewährleistet ist. Hierzu ist es erforderlich die beiden Betonleitwände, die in einem Abstand zueinander angeordnet sind, über ein Element miteinander zu verbinden, durch das die Kräfte entsprechend aufgenommen und in die Betonleitwände eingeleitet werden können. Entsprechende Elemente sind unabhängig von dem Vorhandensein von Schachtabdeckungen auch dann erforderlich, wenn zwei in einem Abstand zueinander angeordnete Betonleitwände sicher miteinander verbunden werden sollen.For roadway limitation, the provision of Betonleitwänden is known. These are usually stepped in cross-section concrete elements, which are provided in the longitudinal direction with reinforcing elements such as wire ropes. Such concrete guide walls are for example in DE 101 45 647 and DE 10 2005 030 412 described. Concrete guide walls are usually produced directly on site from in-situ concrete. In particular, in the arrangement of Betonleitwänden on existing lanes, but also in new buildings, there is the problem that manhole covers such as Gullideckel or the like would be placed under this after completion of the concrete wall. However, the manhole covers must be accessible for regular maintenance and the like. On the other hand, it must also be ensured that the protection achieved by the concrete guide wall, ie the retention of motor vehicles in the event of an impact, is also ensured in the area of the manhole cover. For this purpose, it is necessary to connect the two concrete guide walls, which are arranged at a distance from one another, via an element, by which the forces are correspondingly received and introduced into the concrete guide walls can be. Corresponding elements are also required, regardless of the presence of manhole covers, when two concrete guide walls arranged at a distance from one another are to be securely connected to one another.

Aufgabe der Erfindung ist es, ein Überbrückungselement zum Überbrücken eines Abstandes zwischen zwei Betonleiwänden, sowie ein entsprechendes Fahrbahnbegrenzungselement zu schaffen, mit dem bei hoher Anfahrsicherheit die beiden beabstandeten Betonleitwände miteinander verbunden werden können.The object of the invention is to provide a bridging element for bridging a distance between two Betonleiwänden, as well as a corresponding roadway boundary element, with the two spaced concrete guide walls can be connected to each other at high starting safety.

Die Lösung der Aufgabe erfolgt durch ein Überbrückungselement gemäß Anspruch 1 bzw. ein Fahrbahnbegrenzungselement gemäß Anspruch 13.The object is achieved by a bridging element according to claim 1 or a roadway limiting element according to claim 13.

Das erfindungsgemäße Überbrückungselement zum Überbrücken eines Abstandes zwischen zwei benachbarten Betonleitwänden ist insbesondere zur Überbrückung im Bereich von Abdeckungen eines Schachts oder dergleichen geeignet. Das Überbrückungselement weist erfindungsgemäß zwei Kupplungsvorrichtungen auf. Jede Kupplungsvorrichtung ist hierbei mit einer der beiden Betonleitwände derart verbunden, dass die Kupplungsvorrichtung mit den in der Betonleitwand vorgesehenen Bewehrungselementen zur Kraftübertragung verbindbar ist. Die Verbindung mit den Bewehrungselementen ist erfindungsgemäß wichtig, da bei einem Aufprall die Kraft insbesondere durch die Bewehrungselemente übertragen bzw. aufgenommen wird. Die beiden mit den aus den Betonleitwänden ragenden Bewehrungselementen verbundenen Kupplungsvorrichtungen sind zur Kraftübertragung durch ein Verbindungselement miteinander verbunden. Das insbesondere aus Stahl-Bauteilen hergestellte Verbindungselement dient zur Übertragung von Kräften zwischen den beiden Kupplungsvorrichtungen. Durch Vorsehen des erfindungsgemäßen Überbrückungselements wird die durch einen Aufprall beispielsweise kurz vor dem Ende einer Betonleitwand in diese eingeleitete Kraft über die mit der Betonleitwand verbundenen Kupplungsvorrichtung in das Verbindungselement und von dem Verbindungselement über die zweite Kupplungsvorrichtung in die anschließende Betonleitwand übertragen. Ohne das Vorsehen des erfindungsgemäßen Überbrückungselements bestünde die Gefahr, dass ein Fahrzeug kurz vor dem Ende der beiden Betonleitwände gegen diese prallt, die Betonleitwand seitlich, d.h. quer zu ihrer Längsrichtung verschoben wird und das Fahrzeug sodann frontal gegen die Stirnseite der benachbarten Betonleitwand prallt. Hierbei können schwere Unfälle erfolgen. Diese Gefahr ist durch die Erfindung erheblich reduziert.The bridging element according to the invention for bridging a distance between two adjacent concrete guide walls is particularly suitable for bridging in the region of covers of a shaft or the like. The bridging element has two coupling devices according to the invention. Each coupling device is in this case connected to one of the two concrete guide walls in such a way that the coupling device can be connected to the reinforcement elements provided in the concrete guide wall for power transmission. The connection with the reinforcing elements is important according to the invention, since in a collision the force is transmitted or absorbed in particular by the reinforcing elements. The two associated with the protruding from the Betonleitwänden reinforcing elements coupling devices are connected together for power transmission by a connecting element. The connecting element, in particular made of steel components, serves to transmit forces between the two coupling devices. By providing the bridging element according to the invention, the force introduced by an impact, for example, shortly before the end of a concrete guide wall, is connected to the force which is connected to the concrete guide wall Coupling device in the connecting element and transmitted from the connecting element via the second coupling device in the subsequent concrete guide. Without the provision of the bridging element according to the invention there would be the danger that a vehicle collides against the latter just before the end of the two concrete guide walls, the concrete guide wall is displaced laterally, ie transversely to its longitudinal direction, and the vehicle then collides head-on against the front side of the adjacent concrete guide wall. This can lead to serious accidents. This danger is considerably reduced by the invention.

Vorzugsweise weist jede der beiden Kupplungsvorrichtungen mehrere Kupplungselemente auf. Die einzelnen Kupplungselemente sind hierbei jeweils mit einem der Bewehrungselemente, wie einem Bewehrungsstab, zur Kraftübertragung verbunden. Diese erfolgt beispielsweise durch speziell ausgebildete Muffen. Diese werden vorzugsweise über auf die Bewehrungsstäbe aufgeschnittene Gewinde mit den Bewehrungselementen verbunden.Preferably, each of the two coupling devices has a plurality of coupling elements. The individual coupling elements are each connected to one of the reinforcing elements, such as a reinforcing bar, for power transmission. This is done for example by specially trained sleeves. These are preferably connected via cut on the reinforcing bars thread with the reinforcing elements.

An der Außenseite oder der Innenseite der Muffen können Gewinde vorgesehen sein, so dass die Muffen mit einer Mutter oder Schraube verbunden werden können. Geeignete Muffen sind beispielsweise Lenton Kombinationsmuffen S13, für Betonstahldurchmesser 16 mm der Firma ERICO International Corporation.Threads may be provided on the outside or inside of the sleeves so that the sleeves can be connected to a nut or screw. Suitable sleeves are, for example, Lenton combination sleeves S13, for reinforcing steel diameter 16 mm from ERICO International Corporation.

Bei einer weiteren geeigneten Ausführungsform der Muffen werden diese ebenfalls beispielsweise durch ein auf die Bewehrungsstäbe aufgeschnittenes Gewinde mit diesen verbunden. Die Muffen selber sind an der von den Bewehrungselementen weg weisenden Seite angefasst, so dass auf gute Weise ein Verschweißen möglich ist. Es handelt sich hierbei beispielsweise um Muffen LENTON Anschweißmuffen, Typ C12.In a further suitable embodiment of the sleeves, these are also connected, for example, by a cut onto the reinforcing bars thread with these. The sleeves themselves are touched on the facing away from the reinforcing elements side, so that in a good way welding is possible. These are, for example, sleeves LENTON weld-on sockets, type C12.

Die einzelnen Kupplungselemente sind jeweils über ein gemeinsames Halteelement miteinander verbunden. Es bestehen somit zwei Halteelemente, die jeweils mit den Kupplungselementen der einen bzw. der anderen Betonleitwand verbunden sind. Die beispielsweise fünf Bewehrungsstäbe einer Betonleitwand sind somit über das Halteelement miteinander verbunden.The individual coupling elements are each connected to one another via a common holding element. There are thus two holding elements, which are each connected to the coupling elements of one or the other concrete guide. The example, five reinforcing bars a Betonleitwand are thus connected to each other via the holding element.

Um möglichst hohe Kräfte von den einzelnen Kupplungselementen auf das Halteelement übertragen zu können, weisen die Kupplungselemente in bevorzugter Ausführungsform ein Kopfelement auf, wobei bei dieser Ausführungsform vorzugsweise die LENTON Kombinationsmuffen, Typ S13 verwendet werden. Das Kopfelement dient zur Kraftübertragung von den Kupplungselementen auf das Halteteil. Hierzu ist das Kopfelement vorzugsweise auf einer Innenseite des jeweiligen Halteelements, d.h. auf den beiden aufeinander zu weisenden Seiten des Halteelements angeordnet. Ein Aufprall eines Fahrzeugs bewirkt ein Ziehen an den Bewehrungselementen. Diese Zugkräfte werden über das Kopfteil sodann unmittelbar in das Halteteil eingebracht.In order to be able to transmit as high forces as possible from the individual coupling elements to the retaining element, the coupling elements in a preferred embodiment have a head element, in which embodiment the LENTON combination sleeves type S13 are preferably used. The head element serves to transmit power from the coupling elements to the holding part. For this purpose, the head element is preferably on an inner side of the respective holding element, i. arranged on the two mutually facing sides of the holding element. A collision of a vehicle causes a pulling on the reinforcing elements. These tensile forces are then introduced directly into the holding part via the head part.

Das Kopfteil wird hierbei vorzugsweise mit dem freien Ende der Bewehrungselemente bzw. den mit den Bewehrungselementen verbundenen Kupplungselementen verbunden. In besonders bevorzugter Ausführungsform sind die Kupplungselemente hierbei hülsenförmig ausgebildet und beispielsweise durch Verschrauben oder Verschweißen mit den Enden der Bewehrungselemente fest verbunden. Hierzu werden die insbesondere stabförmigen Bewehrungselemente zumindest teilweise in die Hülse eingesteckt bzw. eingeschraubt. Weiter ist es bevorzugt, dass die Hülsen ein Außen- oder Innengewinde aufweisen. Es ist sodann möglich als Kopfteil eine Mutter oder Schraube vorzusehen.The head part is in this case preferably connected to the free end of the reinforcing elements or the coupling elements connected to the reinforcing elements. In a particularly preferred embodiment, the coupling elements are in this case sleeve-shaped and firmly connected, for example, by screwing or welding to the ends of the reinforcing elements. For this purpose, the particular rod-shaped reinforcing elements are at least partially inserted or screwed into the sleeve. Further, it is preferred that the sleeves have an external or internal thread. It is then possible to provide a nut or screw as the head part.

Zur Montage werden in besonders bevorzugter Ausführungsform die mit Kupplungselementen versehenen Bewehrungselemente durch in Längsrichtung der Betonleitwände verlaufende Öffnungen, wie Durchgangsbohrungen der Halteelemente, gesteckt. Sodann wird auf der Innenseite des jeweiligen Halteelements das Kopfteil wie die Mutter mit dem Kupplungselement verbunden.For mounting in a particularly preferred embodiment, the reinforcing elements provided with coupling elements by extending in the longitudinal direction of the concrete guide openings, such as through holes Retaining elements, inserted. Then, the head part as the mother is connected to the coupling element on the inside of the respective holding element.

Bei einer weiteren bevorzugten Ausführungsform, bei der insbesondere die LENTON Anschweißmuffen, Typ C12 verwendet werden, erfolgt ein Verbinden, insbesondere Verschweißen der Kupplungselemente mit einer Außenseite des Halteelements. Besonders bevorzugt ist es bei dieser Ausführungsform, dass die Enden der Bewehrungselemente zusammen mit den Muffen innerhalb der Betonleitwand angeordnet werden bzw. einbetoniert werden. Auch die Außenseite des Halteelements ist hierbei vorzugsweise innerhalb der Betonleitwand angeordnet. Die Außenseite des Halteelements liegt somit entweder an der Stirnseite der Betonleitwand an oder ragt etwas in diese hinein. Dies hat den Vorteil, dass die verwendeten Muffen nicht aus korrosionsfreiem Material, wie V2A-Stahl, hergestellt sein müssen. Aufgrund des Einbetonierens der Muffe ist diese vor Korrosion geschützt.In a further preferred embodiment, in which in particular the LENTON weld-on sleeves, type C12 are used, there is a connection, in particular welding of the coupling elements to an outer side of the retaining element. It is particularly preferred in this embodiment, that the ends of the reinforcing elements are arranged together with the sleeves within the Betonleitwand or be concreted. The outside of the retaining element is hereby preferably arranged within the concrete guide wall. The outside of the retaining element is thus either on the front side of the Betonleitwand or protrudes slightly into it. This has the advantage that the sleeves used must not be made of corrosion-free material, such as V2A steel. Due to the Einbetonierens the sleeve is protected from corrosion.

In einer besonders bevorzugten Ausführungsform erfolgt das Verbinden des Verbindungselements mit den beiden Halteelementen an der Kupplungsvorrichtung. Hierzu weist das Verbindungselement jeweils ein Kraftübertragungselement auf, das mit dem jeweiligen Halteelement verbunden ist. Bei dem Kraftübertragungselement kann es sich um einen quer zur Längsrichtung verlaufenden Ansatz handeln, so dass das Verbindungselement das Halteelement teilweise umgreift.In a particularly preferred embodiment, the connection of the connecting element with the two holding elements takes place on the coupling device. For this purpose, the connecting element in each case has a force transmission element, which is connected to the respective holding element. The force transmission element can be a shoulder running transversely to the longitudinal direction, so that the connection element partially surrounds the retaining element.

Da die Montage hierdurch erheblich vereinfacht und hohe Kräfte aufgenommen werden können, handelt es sich bei den Kraftübertragungselementen in bevorzugter Ausführungsform um Stifte, insbesondere um Schrauben. Die stiftförmigen Kraftübertragungselemente werden hierbei in Öffnungen des Halteelements, die insbesondere quer zur Längsachse verlaufen, eingesteckt und beispielsweise durch Muttern fixiert.Since the assembly can thereby be considerably simplified and high forces can be absorbed, the force transmission elements in a preferred embodiment are pins, in particular screws. The pin-shaped force transmission elements are in this case inserted into openings of the holding element, which extend in particular transversely to the longitudinal axis, and fixed, for example by nuts.

Bevorzugt ist es, dass das Verbindungselement mindestens zweiteilig ausgebildet ist. Insbesondere weist das Verbindungselement zwei einander gegenüberliegende plattenförmige Verbindungsteile auf. Diese werden zur Verbindung an die beiden Außenseiten der Halteelemente angelegt und über die Kraftübertragungselemente, wie quer zur Längsrichtung angeordnete Schrauben, verbunden.It is preferred that the connecting element is formed at least in two parts. In particular, the connecting element has two opposing plate-shaped connecting parts. These are applied for connection to the two outer sides of the holding elements and connected via the power transmission elements, such as arranged transversely to the longitudinal direction screws.

In montiertem Zustand erfolgt bei einem Aufprall somit die Übertragung von Zugkräften über die Bewehrungselemente in die Kupplungselemente. Von den Kupplungselementen, insbesondere den Kopfteilen der Kupplungselemente, erfolgt eine Übertragung der Kraft auf die Innenseite des jeweiligen Halteelements. Von dem Halteelement wird die Kraft insbesondere über die Kraftübertragungselemente, wie quer angeordnete Schrauben, auf das Verbindungselement übertragen. Von diesem erfolgt die Kraftübertragung sodann in umgekehrter Reihenfolge wieder in die Bewehrungselemente der anderen Betonleitwand.When mounted, the transmission of tensile forces on the reinforcing elements in the coupling elements takes place in an impact. Of the coupling elements, in particular the head parts of the coupling elements, there is a transfer of force to the inside of the respective holding element. Of the retaining element, the force is transmitted in particular via the power transmission elements, such as transversely arranged screws, on the connecting element. From this, the power transmission then takes place in reverse order again in the reinforcing elements of the other Betonleitwand.

Ferner betrifft die Erfindung ein Fahrbahnbegrenzungselement mit zwei in einem Abstand zueinander angeordneten Betonleitwänden. Der in Längsrichtung bestehende Abstand zwischen den beiden Betonleitwänden wird durch das vorstehend beschriebene Überbrückungselement überbrückt. Um eine weiterhin möglichst stufenfreie Außenseite zu gewährleisten und im Fall eines Aufpralls eines Kraftfahrzeugs ein möglichst gutes Ableiten zu ermöglichen, ist in bevorzugter Ausführungsform eine Abdeckhaube vorgesehen. Die Abdeckhaube liegt in ihren beiden Endbereichen auf den Endbereichen der beiden Betonleitwände auf. Vorzugsweise sind die Betonleitwände an ihren Enden abgefräst bzw. weisen eine Abstufung auf. Die Tiefe der Stufe entspricht im Wesentlichen der Dicke des Materials der Abdeckhaube, so dass eine durchgehende, im Wesentlichen ebene Oberseite verwirklicht ist. Die Außenkontur der Abdeckhaube entspricht vorzugweise der Außenkontur der Betonleitwände.Furthermore, the invention relates to a roadway boundary element with two spaced apart Betonleitwänden. The longitudinal distance between the two Betonleitwänden is bridged by the bridging element described above. In order to ensure an as possible stepless as possible outside and in the event of an impact of a motor vehicle to allow the best possible derivation, a cover is provided in a preferred embodiment. The cover lies in its two end regions on the end regions of the two concrete guide walls. Preferably, the Betonleitwände are milled off at their ends or have a gradation. The depth of the step substantially corresponds to the thickness of the material of the cover, so that a continuous, substantially flat top is realized. The outer contour of the cover preferably corresponds to the outer contour of the concrete guide walls.

Die Abdeckhaube kann beispielsweise über Schrauben und Dübel mit den Enden der Betonleitwände im Bereich der Überdeckung verbunden werden. Zusätzlich oder anstelle dieser Verbindung kann eine Verbindung der Abdeckhaube mit dem Verbindungselement erfolgen. Hierzu weist das Verbindungselement beispielsweise an seiner Oberseite ein im Wesentlichen eine horizontale Oberseite ausbildendes Zwischenelement auf. Auf diesem Zwischenelement kann die Abdeckhaube aufliegen und verschraubt werden. Ein weiteres Zwischenelement kann an der Unterseite des Verbindungselements vorgesehen sein. Hierbei kann es sich insbesondere um ein entsprechend abgewinkeltes Blechteil handeln, das einerseits mit dem Verbindungselement durch Verschrauben oder dergleichen verbunden ist und andererseits an einer Innenseite der Abdeckhaube anliegt, wobei auch in diesem Bereich beispielsweise durch Verschrauben eine Verbindung erfolgen kann.The cover can be connected, for example via screws and dowels with the ends of the concrete guide walls in the overlap. In addition to or instead of this connection, a connection of the cover can be made with the connecting element. For this purpose, the connecting element, for example, on its upper side on a substantially horizontal upper surface forming intermediate element. On this intermediate element, the cover can rest and be screwed. Another intermediate element may be provided on the underside of the connecting element. This may in particular be a correspondingly angled sheet metal part, which is connected on the one hand with the connecting element by screwing or the like and on the other hand rests against an inner side of the cover, wherein in this area, for example by screwing a connection can be made.

Da sowohl die Abdeckhaube als auch das Verbindungselement in bevorzugter Ausführungsform durch lösbare Fixierelemente gehalten ist, ist beispielsweise eine Schachtabdeckung auf einfache Weise durch entsprechende Demontage zugänglich.Since both the cover and the connecting element is held in a preferred embodiment by releasable fixing elements, for example, a manhole cover is easily accessible by appropriate disassembly.

Nachfolgend wird die Erfindung anhand bevorzugter Ausführungsformen unter Bezugnahme auf die anliegenden Zeichnungen näher erläutert.The invention will be explained in more detail below with reference to preferred embodiments with reference to the accompanying drawings.

Das erfindungsgemäße Übergangselement ist in den Figuren 1 und 2 dargestellt. Hierbei ist das Übergangselement mit einer ersten Betonleitwand 10 und einer zweiten Betonleitwand 12 verbunden. Eine Abdeckhaube 14 (Fig. 4 und 5) des Fahrbahnbegrenzungselements ist in Fig. 1 und 2 nicht dargestellt.The transition element according to the invention is in the FIGS. 1 and 2 shown. Here, the transition element is connected to a first concrete guide wall 10 and a second concrete guide wall 12. A cover 14 ( 4 and 5 ) of the roadway boundary element is in Fig. 1 and 2 not shown.

In den beiden Betonleitwänden 10, 12 sind jeweils fünf sich in Längsrichtung 16 erstreckende Bewehrungsstäbe 18 vorgesehen. Die beiden Betonleitwände 10, 12 weisen einen Abstand a zueinander auf, wobei die Bewehrungselemente 18 aus den Stirnseiten 20 hervorragen. Zwischen den beiden Stirnseiten 20, d.h. zwischen den beiden Betonleitwänden 10, 12 ist beispielsweise eine Schachtabdeckung 22 vorgesehen, die zugänglich sein muss.In the two Betonleitwänden 10, 12 five each extending in the longitudinal direction 16 reinforcing rods 18 are provided. The two concrete guide walls 10, 12 have a distance a from each other, wherein the reinforcing elements 18 protrude from the end faces 20. Between the two end faces 20, i. between the two Betonleitwänden 10, 12, for example, a manhole cover 22 is provided, which must be accessible.

Zur Verbindung der Bewehrungselemente 18 sind die Bewehrungselemente 18 jeweils mit einer Kupplungsvorrichtung 24 verbunden. Die beiden Kupplungsvorrichtungen 24 sind sodann mit einem Verbindungselement 26 verbunden.To connect the reinforcing elements 18, the reinforcing elements 18 are each connected to a coupling device 24. The two coupling devices 24 are then connected to a connecting element 26.

Die beiden Kupplungsvorrichtungen 24 weisen mehrere Kupplungselemente 28 auf, wobei in der dargestellten bevorzugten Ausführungsform das Kupplungselement 28 eine Hülse 30 aufweist, die beispielsweise durch Verschweißen oder Verquetschen mit dem jeweiligen Bewehrungselement 18 verbunden ist. Hierbei ragt das Bewehrungselement 18 in die Hülse 30 hinein. Die Hülse 30 weist ein Innengewinde auf, in das zur Ausbildung eines Kopfteils des Kupplungselements 28 eine Schraube 32 eingeschraubt ist.The two coupling devices 24 have a plurality of coupling elements 28, wherein in the illustrated preferred embodiment, the coupling element 28 has a sleeve 30, for example, by welding or crimping with the respective reinforcing element 18th connected is. In this case, the reinforcing element 18 projects into the sleeve 30. The sleeve 30 has an internal thread into which a screw 32 is screwed in to form a head part of the coupling element 28.

Um die einzelnen Kupplungselemente 28 der jeweiligen Kupplungsvorrichtung 24 miteinander zu verbinden, ist jeweils ein Halteelement 34 vorgesehen, bei dem es sich im Wesentlichen um ein quaderförmiges Bauteil handelt. Das Halteelement 34 weist in Längsrichtung 16 verlaufende Durchgangsbohrungen 36 auf, wobei jede Durchgangsbohrung 36 einem Kupplungselement 28 zugeordnet ist.To connect the individual coupling elements 28 of the respective coupling device 24 with each other, a holding element 34 is provided, which is essentially a cuboid component. The holding element 34 has through bores 36 extending in the longitudinal direction 16, each throughbore 36 being associated with a coupling element 28.

Bei einer weiteren alternativen Ausführungsform (Fig. 3) sind dieselben und ähnliche Bauteile entsprechend der ersten Ausführungsform (Fig. 1 und 2) mit denselben Bezugszeichen gekennzeichnet.In a further alternative embodiment ( Fig. 3 ) are the same and similar components according to the first embodiment ( Fig. 1 and 2 ) are identified by the same reference numerals.

Der wesentliche Unterschied der beiden Ausführungsformen besteht in der Ausgestaltung der verwendeten Muffen. Die Muffen bzw. Kupplungselemente 29 werden wie vorstehend anhand der Muffe 28 beschrieben mit den Enden der Bewehrungselemente 18 beispielsweise durch Verschweißen verbunden. Die Muffen 18 weisen jedoch kein Innengewinde auf, so dass ein Verbinden über eine Schraubverbindung mit den Halteelementen 34 erfolgen kann. Vielmehr werden die Muffen 29 durch Verschweißen mit Außenseiten 31 eines Halteelements 33 verbunden. Das Halteelement 33 ist im Querschnitt entsprechend dem Halteelement 34 U-förmig, wobei der geschlossene Teil jedoch in Richtung der Betonleitwand 12 weist. Ein wesentlicher Aspekt der in Fig. 3 dargestellten Ausführungsform besteht darin, dass eine Schweißnaht 35, mit der die Muffen 29 an der Außenseite 31 des Halteelements 33 verschweißt sind, innerhalb der Betonleitwand 12 angeordnet sind. Auch die Stirnseite 31 des Halteelements 33 ist in bevorzugter Ausführungsform innerhalb der Betonleitwand 12 angeordnet oder liegt zumindest an einer Stirnseite 37 der Betonleitwand 12 an.The main difference between the two embodiments is the design of the sleeves used. The sleeves or coupling elements 29 are as described above with reference to the sleeve 28 connected to the ends of the reinforcing elements 18, for example by welding. However, the sleeves 18 have no internal thread, so that a connection can be made via a screw connection with the holding elements 34. Rather, the sleeves 29 are connected by welding to outer sides 31 of a holding element 33. The holding element 33 is U-shaped in cross section corresponding to the holding element 34, wherein the closed part, however, points in the direction of the concrete guide wall 12. An essential aspect of in Fig. 3 illustrated embodiment is that a weld seam 35, with which the sleeves 29 are welded to the outside 31 of the holding member 33, are disposed within the concrete guide wall 12. Also, the end face 31 of the holding element 33 is arranged in a preferred embodiment within the Betonleitwand 12 or is at least at one end face 37 of the concrete guide 12 at.

Die Befestigung des Halteelements 33 mit den Verbindungselementen 38 erfolgt, wie vorstehend anhand der ersten Ausführungsform beschrieben, über Schrauben 42.The fastening of the retaining element 33 with the connecting elements 38 takes place, as described above with reference to the first embodiment, via screws 42.

Zur Montage werden zunächst die Bewehrungselemente 18 mit den Hülsen 30 verbunden. Sodann werden die im ersten Ausführungsbeispiel fünf Bewehrungselemente bzw. die fünf mit diesen verbundenen Hülsen 30 (Fig. 2) durch die Öffnungen 36 des entsprechenden Haltelements 34 geschoben. Sodann werden die Schrauben 32 in die Hülsen 30 geschraubt. Je nachdem wie weit die Schrauben 32 in die Hülsen 30 geschraubt sind, kann ein Längenausgleich bzw. ein Ausgleich von Toleranzen erfolgen. Dies ist insbesondere zu der nachfolgend beschriebenen Montage des Verbindungselements 26 wichtig.For assembly, first the reinforcing elements 18 are connected to the sleeves 30. Then, in the first embodiment, five reinforcing elements or the five associated with these sleeves 30 (FIG. Fig. 2 ) is pushed through the openings 36 of the corresponding holding element 34. Then, the screws 32 are screwed into the sleeves 30. Depending on how far the screws 32 are screwed into the sleeves 30, a length compensation or compensation of tolerances can take place. This is particularly important for the assembly of the connecting element 26 described below.

Bei der zweiten Ausführungsform (Fig. 3), bei der verschweißbare Hülsen 29 verwendet werden, erfolgt ein Verschweißen der im dargestellten Ausführungsbeispiel fünf Hülsen 29 mit der Außenseite 31 des Halteelements 33.In the second embodiment ( Fig. 3 ), are used in the weldable sleeves 29, welding takes place in the illustrated embodiment, five sleeves 29 with the outside 31 of the holding member 33rd

Das Verbindungselement 26 weist zwei einander gegenüberliegende plattenförmige Verbindungsteile 38 (Fig. 2 oder 3) auf. Im dargestellten Ausführungsbeispiel handelt es sich bei den Verbindungsteilen 38 um ebene Platten, die an Außenseiten 40 der beiden Halteelemente 34 anliegen. Zur Verbindung der beiden Verbindungsteile 38 mit den Halteelementen 34 sind Kraftübertragungselemente 42 vorgesehen, bei denen es sich im dargestellten Ausführungsbeispiel um Schrauben handelt. Durch die Schrauben 42 erfolgt eine Kraftübertragung von den Halteelementen 34 auf die Verbindungsteile 38.The connecting element 26 has two mutually opposite plate-shaped connecting parts 38 (FIG. Fig. 2 or 3 ) on. In the illustrated embodiment, the connecting parts 38 are flat plates which abut against outer sides 40 of the two holding elements 34. To connect the two connecting parts 38 with the holding elements 34, power transmission elements 42 are provided, which are screws in the illustrated embodiment. By means of the screws 42, a force is transmitted from the holding elements 34 to the connecting parts 38.

Die beiden Verbindungsteile 38 sind im Querschnitt im Wesentlichen C-förmig ausgebildet (Fig. 5). Hierbei bilden die beiden in Fig. 4 oberen Ansätze 44 eine horizontale Auflage für die Haube 14. Die Haube 14 kann sodann über Schrauben an den Ansätzen 44 befestigt werden.The two connecting parts 38 are formed in cross-section substantially C-shaped ( Fig. 5 ). Here are the two in Fig. 4 upper lugs 44 a horizontal support for the hood 14. The hood 14 can then be secured by screws on the lugs 44.

An den unteren Ansätzen 44 der Verbindungsteile 38 ist ein ebenfalls aus Stahlblech oder dergleichen hergestelltes Zwischenteil 46 vorgesehen. Dieses ist im Querschnitt ebenfalls C-förmig ausgebildet und weist in Fig. 4 nach oben weisende Ansätze auf. Diese Ansätze sind parallel zu den Innenseiten der beiden Seitenteile 48 der Haube 14. An diesen Ansätzen kann über Schrauben 50 (Fig. 4) die Haube 14 befestigt werden. Die Haube 14 wird in bevorzugter Ausführungsform von oben aufgesetzt und sodann wie vorstehend beschrieben mit dem Verbindungselement 26 verschraubt. Um einen stufenfreien Übergang zwischen der Außenseite der beiden Betonleitwände 10, 12 und der Haube 14 zu gewährleisten, weisen die beiden Betonelemente 10, 12 in ihren Endbereichen eine Abstufung 52 (Fig. 1) auf. Die Abstufung 52 ist von der Haube 14 überdeckt (Fig. 4).At the lower lugs 44 of the connecting parts 38, an intermediate part 46, likewise made of sheet steel or the like, is provided. This is also C-shaped in cross section and has in Fig. 4 upward pointing approaches. These lugs are parallel to the insides of the two side parts 48 of the hood 14. These approaches can be done via screws 50 (FIG. Fig. 4 ) the hood 14 are attached. The hood 14 is placed in a preferred embodiment from above and then screwed as described above with the connecting element 26. In order to ensure a smooth transition between the outside of the two concrete guide walls 10, 12 and the hood 14, the two concrete elements 10, 12 in their end regions a gradation 52 (FIG. Fig. 1 ) on. The gradation 52 is covered by the hood 14 ( Fig. 4 ).
