Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Verbinden und zur Aufnahme von Querkräften von zwei durch eine Fuge getrennten Bauteilen, insbesondere aus Beton, gemäss dem Oberbegriff des Patentanspruches 1.The present invention relates to a device for connecting and absorbing transverse forces of two components separated by a joint, in particular made of concrete, according to the preamble of patent claim 1.

Derartige Vorrichtungen werden zur Verbindung von Bauteilen des Hoch- und Tiefbaues wie Dachplatten, Bodenplatten, Decken, Wände, Träger, Stützen, Stützmauern oder Teilen hiervon miteinander oder mit anderen Bauteilen verwendet. Diese Bauteile sind in den meisten Fällen aus Beton gefertigt, es sind aber auch andere Materialien denkbar. Hierzu wird der Hülsenteil in einem der zu verbindenden Bauteile, der Dornteil im damit zu verbindenden Bauteil derart angeordnet, dass der Dorn aus dem betreffenden Bauteil vorsteht und im Endzustand in die im anderen Bauteil angeordnete Hülse eindringt. Dadurch können die zwischen den Bauteilen auftretenden Querkräfte übertragen werden. Neben der Möglichkeit, quer zur Längsachse erhebliche Kräfte aufzunehmen, muss der Dorn in der Hülse längs frei verschieblich sein und bleiben, damit sich die Bauteile unter dem Einfluss unterschiedlicher Temperaturen sowie auch in Folge von Schwind- und Kriecheinflüssen zwangslos ausdehnen und zusammenziehen können.Such devices are used to connect building and civil engineering components such as roof panels, floor panels, ceilings, walls, beams, supports, retaining walls or parts thereof with each other or with other components. In most cases, these components are made of concrete, but other materials are also conceivable. For this purpose, the sleeve part is arranged in one of the components to be connected, the mandrel part in the component to be connected in such a way that the mandrel protrudes from the relevant component and in the final state penetrates into the sleeve arranged in the other component. As a result, the transverse forces occurring between the components can be transmitted. In addition to the possibility of absorbing considerable forces transversely to the longitudinal axis, the mandrel in the sleeve must be freely movable and remain longitudinally so that the components can expand and contract under the influence of different temperatures and also as a result of shrinkage and creep influences.

Das Hauptproblem bei derartigen Vorrichtungen zur Verbindung von Bauteilen, beispielsweise aus Beton, sind die sehr hohen lokalen Betonpressungen unter dem Stahldorn am Fugenrand. Hierbei besteht die Gefahr des Ausbrechens des Betons am Fugenrand, womit eine akute Gefährdung der Tragsicherheit der Dornkonstruktion auftreten kann. Um diese Betonpressungen in zulässigen Grenzen zu halten, müsste bei einer einfachen Dorn-Hülsen-Anordnung zur Verbindung von zwei Bauteilen eine grosse Zahl von Dornen und Hülsen angeordnet werden. Da die Dorne und Hülsen aus einem korrosionsfesten Material, beziehungsweise aus einem korrosionsgeschützten Material bestehen müssen, wird eine derartige Lösung teuer, wobei auch der Arbeitsaufwand zum Verlegen dieser Dorne und Hülsen gross ist.The main problem with such devices for connecting components, for example made of concrete, are the very high local concrete pressures under the steel mandrel at the edge of the joint. There is a risk of the concrete breaking out at the edge of the joint, which can lead to an acute risk to the structural safety of the mandrel construction. In order to keep these concrete pressures within permissible limits, a large number of mandrels and sleeves would have to be arranged in a simple mandrel-sleeve arrangement for connecting two components. Since the mandrels and sleeves must consist of a corrosion-resistant material or a corrosion-protected material, such a solution becomes expensive, and the work involved in laying these mandrels and sleeves is also great.

Eine Möglichkeit, die Betonpressungen in zulässigen Grenzen zu halten, besteht darin, dass durch Anordnen eines massiven Lagerkörpers zwischen dem Dorn bzw. der Hülse und dem umgebenden Beton die auftretende Kraft über eine grössere Oberfläche auf den Beton übertragen wird. Derartige Lagerkörper sind beispielsweise in der US-A-2 194 718 dargestellt. Da die hier gezeigten Lagerkörper insbesondere versteift wurden, treten druckseitig immer noch örtlich hohe Betonpressungen auf, da die Einleitung der Kraft nicht optimal ist.One way to keep the concrete pressures within permissible limits is that by arranging a solid bearing body between the mandrel or the sleeve and the surrounding concrete, the force occurring is transmitted to the concrete over a larger surface. Such bearing bodies are shown for example in US-A-2 194 718. Since the bearing bodies shown here have been stiffened in particular, high concrete pressures still occur on the pressure side, since the introduction of the force is not optimal.

In der EP-B-0 032 105 sind ebenfalls entsprechende massive Lagerkörper gezeigt, die gegenüber dem Dorn bzw. der Hülse elastisch nachgiebiger sind, wodurch die auftretenden Spitzenwerte der Betonpressung verkleinert werden und die Querkräfte gleichmässiger übertragen werden können.EP-B-0 032 105 also shows corresponding solid bearing bodies which are elastically more flexible with respect to the mandrel or the sleeve, as a result of which the peak values of the concrete pressure which occur are reduced and the transverse forces can be transmitted more uniformly.

Die Aufgabe der Erfindung besteht nun darin, die extrem hohen Pressungen des Materials der entsprechenden Bauteile unter dem Dorn und der Hülse am Fugenrand weiter zu verkleinern.The object of the invention is now to further reduce the extremely high pressures of the material of the corresponding components under the mandrel and the sleeve at the edge of the joint.

Erfindungsgemäss erfolgt die Lösung dieser Aufgabe durch die in der Kennzeichnung des Anspruchs 1 angegebenen Merkmale.According to the invention, this object is achieved by the features specified in the characterizing part of claim 1.

Durch diese Ausgestaltung der Halterung des Dorns und der Hülse wird eine direkte Entlastung des Dorns und der Hülse vor dem Eintritt in den Bauteil erreicht. Diese Entlastung erfolgt über die am Fugenrand angeordnete flanschartige Scheibe, wobei die von dieser Scheibe aufgenommene Kraft in die mit der Scheibe verbundene Platte übergeleitet und von dieser in das diese umgebende Material, beispielsweise in den Beton übertragen wird.This configuration of the holder for the mandrel and the sleeve results in a direct relief of the mandrel and the sleeve before it enters the component. This relief takes place via the flange-like disc arranged at the joint edge, the force absorbed by this disc being transferred into the plate connected to the disc and being transmitted by the latter into the material surrounding it, for example into the concrete.

Durch diese erfindungsgemässe Anordnung wird für die Kraftübertragung ein sehr grosser Bereich des umgebenden Materials der Bauteile, beispielsweise des Betons, einbezogen, wodurch ein wesentlich grösserer Bruchwiderstand des Materials der Bauteile erreichbar ist.By means of this arrangement according to the invention, a very large area of the surrounding material of the components, for example the concrete, is included for the power transmission, as a result of which a significantly greater breaking resistance of the material of the components can be achieved.

Eine einfache und kostengünstige Herstellung der Vorrichtung wird erreicht, indem die flanschartige Scheibe und die Platte von Dorn- und Hülsen-anordnung aus einem Stück gebildet werden, was beispielsweise durch Abkantung eines Flachprofils erreicht wird.A simple and inexpensive manufacture of the device is achieved by the flange-like disk and the plate of mandrel and sleeve arrangement be formed from one piece, which is achieved for example by folding a flat profile.

In vorteilhafter Weise kann der in den Bauteil hineinragende Endbereich der Platte einen umgebogenen Teil aufweisen, wodurch die Verankerung der Platte im Bauteil verbessert wird.The end region of the plate projecting into the component can advantageously have a bent part, as a result of which the anchoring of the plate in the component is improved.

Zur weiteren Verbesserung der Verankerung kann der von der flanschförmigen Scheibe abgewandte Endbereich der Platte mit dem in den entsprechenden Bauteil hineinragenden Bereich der Hülse bzw. des Dorns verbunden sein, was beispielsweise über einen Steg erreicht werden kann.To further improve the anchoring, the end region of the plate facing away from the flange-shaped disk can be connected to the region of the sleeve or the mandrel projecting into the corresponding component, which can be achieved, for example, via a web.

Eine vorteilhafte Ausgestaltung der Erfindung besteht darin, dass bezüglich des Dorns oder der Hülse zur Platte eine symmetrisch angeordnete zweite Platte an der flanschförmigen Scheibe angebracht ist, die in vorteilhafter Weise die gleichen Abmessungen aufweist wie die Platte. Dadurch können allfällig wechselnde Kraftrichtungen am gleichen Bauteil optimal aufgenommen werden, zusätzlich wird vermieden, dass auf einer Baustelle die erfindungsgemässe Vorrichtung falsch montiert werden kann, indem beispielsweise die Platte auf die ,,falsche" Seite des Dorns bzw. der Hülse zu liegen kommt.An advantageous embodiment of the invention consists in that, with respect to the mandrel or the sleeve relative to the plate, a symmetrically arranged second plate is attached to the flange-shaped disk, which advantageously has the same dimensions as the plate. As a result, any changing directions of force on the same component can be optimally absorbed; in addition, it is avoided that the device according to the invention can be incorrectly installed on a construction site, for example by the plate coming to rest on the “wrong” side of the mandrel or sleeve.

Weitere vorteilhafte Ausgestaltungen der Erfindung ergeben sich aus den weiteren abhängigen Ansprüchen.Further advantageous embodiments of the invention result from the further dependent claims.

Ausführungsformen der erfindungsgemässen Vorrichtung werden nachfolgend anhand der beiliegenden Zeichnung beispielhaft näher erläutert.Embodiments of the device according to the invention are explained in more detail below by way of example with reference to the accompanying drawing.

In Fig. 1 und Fig. 2 ist jeweils ein Ausschnitt eines ersten Bauteils 1 und eines zweiten Bauteils 2 dargestellt. Die Bauteile 1 und 2, die beispielsweise aus Beton bestehen, sind durch eine Fuge 3 voneinander getrennt. Im ersten Bauteil 1 ist ein Endbereich 4 eines Dorns 5 eingelassen. Im zweiten Bauteil 2 ist eine im wesentlichen rohrförmige Hülse 6 eingelassen, in welche der andere Endbereich 7 des Dorns 5 eindringt. Durch diese Verbindung der beiden Bauteile 1 und 2 können sich diese in Längsachsenrichtung des Dorns 5 bzw. der Hülse 6 relativ zueinander bewegen, beispielsweise zur Aufnahme von Wärmeausdehnungen, während sie quer zum Dorn 5 bzw. der Hülse 6 fix gehalten sind.1 and FIG. 2 each show a section of a first component 1 and a second component 2. The components 1 and 2, which consist for example of concrete, are separated from one another by a joint 3. An end region 4 of a mandrel 5 is embedded in the first component 1. In the second component 2 there is an essentially tubular sleeve 6 into which the other end region 7 of the mandrel 5 penetrates. As a result of this connection of the two components 1 and 2, they can move relative to one another in the longitudinal axis direction of the mandrel 5 or the sleeve 6, for example to absorb thermal expansions, while they are held transversely to the mandrel 5 or the sleeve 6.

Jeweils an den die Fuge 3 bildenden Randbereichen der Bauteile 1 und 2 ist eine flanschartige Scheibe 8 bzw. 9 angeordnet. Diese flanschartigen Scheiben 8 und 9 stehen jeweils rechtwinklig zu Dorn 5 bzw. Hülse 7. Die flanschartige Scheibe 8 wird vom Dorn 5 durchdrungen und ist mit diesem fest verbunden, was beispielsweise durch Verschweissung erfolgt. Die flanschartige Scheibe 9 wird ihrerseits durch die Hülse 6 durchdrungen und ist mit dieser ebenfalls fest verbunden.A flange-like disk 8 or 9 is arranged on the edge regions of the components 1 and 2 forming the joint 3. These flange-like disks 8 and 9 are each perpendicular to the mandrel 5 or sleeve 7. The flange-like disk 8 is penetrated by the mandrel 5 and is firmly connected to it, which is done, for example, by welding. The flange-like disc 9 is in turn penetrated by the sleeve 6 and is also firmly connected to it.

Davon ausgehend, dass der zweite Bauteil 2 ein Stützelement ist und der erste Bauteil 1 ein Brückenelement, wirkt die auf den Beton des Bauteils 2 zu übertragende Reaktionskraft von der Hülse 6 in Fig. 1 in Richtung des Pfeiles B, während die auf den Beton des Bauteils 1 zu übertragende Reaktionskraft des Dornes 5 in Richtung des Pfeiles A wirkt. Demzufolge ist in Fig. 1 für die Hülse 6 die druckbelastete Seite 11 unten, während für den Dorn 5 die druckbelastete Seite 10 oben ist.Assuming that the second component 2 is a support element and the first component 1 is a bridge element, the reaction force to be transmitted to the concrete of the component 2 acts from the sleeve 6 in FIG. 1 in the direction of arrow B, while that on the concrete of the Component 1 to be transmitted reaction force of the mandrel 5 acts in the direction of arrow A. Accordingly, in FIG. 1 the pressure-loaded side 11 is below for the sleeve 6, while the pressure-loaded side 10 is above for the mandrel 5.

An den beiden flanschartigen Scheiben 8 und 9 ist jeweils eine Platte 12 bzw. 13 angebracht, die in den jeweiligen Bauteil 1 bzw. 2 hineinragt. Die beiden Platten 12 und 13 sind parallel zum Dorn 5 und der Hülse 6 ausgerichtet. Die Platten 12 und 13 kommen so in den jeweiligen Bauteil 1 bzw. 2 zu liegen, dass sie der druckbelasteten Seite 10 des Dorns 5 bzw. der druckbelasteten Seite 11 der Hülse 6 gegenüberliegend sind. Die Platten 12 und 13 sind jeweils vom Dorn 5 bzw. der Hülse 6 beabstandet angeordnet.A plate 12 or 13 is attached to each of the two flange-like disks 8 and 9, which protrudes into the respective component 1 or 2. The two plates 12 and 13 are aligned parallel to the mandrel 5 and the sleeve 6. The plates 12 and 13 come to lie in the respective component 1 or 2 in such a way that they are opposite the pressure-loaded side 10 of the mandrel 5 or the pressure-loaded side 11 of the sleeve 6. The plates 12 and 13 are each spaced from the mandrel 5 and the sleeve 6, respectively.

Mit dieser Anordnung wird durch die flanschartige Scheibe 8 die Spitzenbelastung, die am fugenseitigen Rand des Bauteiles 1 auftritt, aufgenommen und über die Platte 12 in vorteilhafter Weise auf den Beton des Bauteiles 1 übertragen. Dadurch werden übermässige örtliche Betonpressungen des Bauteiles 1 insbesondere im fugenseitigen Randbereich vermieden. In derselben Weise erfolgt die Uebertragung der Spitzenbelastung am fugenseitigen Rand des Bauteiles 2 über die flanschartige Scheibe 9 auf die Platte 13 und von dieser auf den Beton. Dadurch kann die Gefahr von Ausbrechungen des Betons am Fugenrand vermieden werden.With this arrangement, the peak load that occurs at the joint-side edge of the component 1 is absorbed by the flange-like disc 8 and is advantageously transmitted to the concrete of the component 1 via the plate 12. As a result, excessive local concrete pressures of the component 1 are avoided, in particular in the edge region on the joint side. In the same way, the transfer of the peak load on the joint-side edge of the component 2 takes place via the flange-like disk 9 to the plate 13 and from this to the concrete. This avoids the risk of the concrete breaking out at the edge of the joint.

Je nach Dimensionen und der Grösse der zu übertragenden Kräfte können Dorn 5 und Hülse 6, flanschartige Scheiben 8 und 9, Platten 12 und 13 und deren Abstand vom Dorn 5 bzw. Hülse 6 entsprechend dimensioniert werden.Depending on the dimensions and the size of the forces to be transmitted, mandrel 5 and sleeve 6, flange-like disks 8 and 9, plates 12 and 13 and their distance from the mandrel 5 or sleeve 6 can be dimensioned accordingly.

Zur besseren Verankerung der Platten 12 und 13 im Beton der Bauteile 1 und 2 weist jeweils der in den Bauteil 1 bzw. 2 hineinragende Endbereich der Platten 12 und 13 einen umgebogenen Teil 14 bzw. 15 auf.For better anchoring of the plates 12 and 13 in the concrete of the components 1 and 2, the end region of the plates 12 and 13 projecting into the component 1 and 2 has a bent part 14 and 15, respectively.

Fig. 3 zeigt eine einfache und günstig herstellbare Ausführungsform eines Dorns 5 mit flanschartiger Scheibe 8 und Platte 12, wobei flanschartige Scheibe 8 und Platte 12 in einfacher Weise durch einmalige Abkantung eines Flachprofils erreicht wird.Fig. 3 shows a simple and inexpensive to manufacture embodiment of a mandrel 5 with flange-like disc 8 and plate 12, flange-like disc 8 and plate 12 being achieved in a simple manner by one-time folding of a flat profile.

Im in Fig. 4 dargestellten Ausführungsbeispiel ist die flanschartige Scheibe 8 und die Platte 12 in gleicher Weise ausgebildet wie in Fig. 3, wobei der Endbereich der Platte 12 nochmals abgewinkelt ist, wodurch ein Steg 16 gebildet wird, der wie die flanschartige Scheibe 8 vom Dorn 5 durchdrungen wird. Mit dieser Ausgestaltung wird eine gute Verankerung insbesondere der Platte 12 im Beton des Bauteils erreicht.In the embodiment shown in FIG. 4, the flange-like disc 8 and the plate 12 are designed in the same way as in FIG. 3, the end region of the plate 12 being angled again, as a result of which a web 16 is formed which, like the flange-like disc 8, Thorn 5 is penetrated. With this configuration, good anchoring, in particular of the plate 12, is achieved in the concrete of the component.

Die in den Fig. 5 bis 7 dargestellten Ausführungsformen zeigen den gleichen Aufbau wie die Ausgestaltungsform nach Fig. 3, bestehend aus flanschartiger Scheibe 8, Platte 12 und Dorn 5, wobei zusätzliche Verankerungselemente 17 vorgesehen sind, welche in der Ausgestaltungsform nach Fig. 5 als Armierungsstäbe 18 ausgebildet sind, die mit der Platte 12 fest verbunden sind, in der Ausgestaltungsform gemäss Fig. 6 aus Verankerungsbolzen 19 bestehen, die senkrecht auf der Platte 12 befestigt sind und die in der Ausgestaltungsform nach Fig. 7 aus Armierungsbügeln 20 gebildet sind, die jeweils an der Platte 12 und an der flanschartigen Scheibe 8 befestigt sind. Mit diesen Vorkehrungen wird eine bessere Verankerung im Beton des jeweiligen Bauteils erreicht.The embodiments shown in FIGS. 5 to 7 show the same structure as the embodiment according to FIG. 3, consisting of flange-like disk 8, plate 12 and mandrel 5, additional anchoring elements 17 being provided, which in the embodiment according to FIG Reinforcing rods 18 are formed, which are fixedly connected to the plate 12, in the embodiment according to FIG. 6 consist of anchoring bolts 19 which are fastened vertically on the plate 12 and which are formed in the embodiment according to FIG. 7 from reinforcing brackets 20 which are each attached to the plate 12 and to the flange-like disk 8. With these precautions, better anchoring in the concrete of the respective component is achieved.

Selbstverständlich sind alle in den Fig. 3 bis 7 dargestellten Ausführungsformen in identischer Weise auch für die Ausgestaltung der Hülse 6 verwendbar.Of course, all of the embodiments shown in FIGS. 3 to 7 can also be used in an identical manner for the configuration of the sleeve 6.

In den Fig. 8 und 9 ist ein weiteres Ausführungsbeispiel der erfindungsgemässen Vorrichtung dargestellt. Wie bei den vorhergehend beschriebenen Ausführungsformen ist ein Dorn 5 und eine Hülse 6 im ersten Bauteil 1 bzw. im zweiten Bauteil 2, die beide durch eine Fuge 3 getrennt sind, eingelassen. Der Dorn 5 dringt hierbei in die Hülse 6 ein. Dorn und Hülse weisen eine flanschartige Scheibe 8 bzw. 9 auf, an welcher jeweils, wie vorgängig beschrieben, eine Platte 12 bzw. 13 angebracht ist. Die Platte 12 und die Platte 13 sind jeweils über einen Steg 16 mit dem hinteren Bereich des Dorns 5 bzw. der Hülse 6 verbunden.8 and 9 show a further exemplary embodiment of the device according to the invention. As in the previously described embodiments, a mandrel 5 and a sleeve 6 are embedded in the first component 1 and in the second component 2, both of which are separated by a joint 3. The mandrel 5 penetrates into the sleeve 6. The mandrel and sleeve have a flange-like disk 8 or 9, on which, as described above, a plate 12 or 13 is attached. The plate 12 and the plate 13 are each connected to the rear region of the mandrel 5 or the sleeve 6 via a web 16.

Bezüglich der Dornachse bzw. Hülsenachse ist symmetrisch zur Platte 12 bzw. 13 jeweils eine zweite Platte 21 bzw. 22 an der flanschartigen Scheibe 8 bzw. 9 angebracht. Der der flanschartigen Scheibe 8 bzw. 9 abgewandte Endbereich dieser zweiten Platte 21 bzw. 22 ist ebenfalls über einen Steg 23 mit dem Dorn 5 bzw. der Hülse 6 verbunden. Die flanschartige Scheibe 8, die Platte 12, Steg 16, zweite Platte 21 und Steg 23 können in einfacher und kostengünstiger Weise durch entsprechende Abbiegungen aus einem Flachprofil hergestellt werden. Entsprechendes gilt für die hülsenseitige Anordnung.With regard to the mandrel axis or sleeve axis, a second plate 21 or 22 is attached to the flange-like disk 8 or 9 symmetrically to the plate 12 or 13. The end region of this second plate 21 or 22 facing away from the flange-like disk 8 or 9 is likewise connected to the mandrel 5 or the sleeve 6 via a web 23. The flange-like disc 8, the plate 12, the web 16, the second plate 21 and the web 23 can be produced in a simple and inexpensive manner by means of appropriate bends from a flat profile. The same applies to the arrangement on the sleeve side.

Durch die symmetrische Anordnung einer zweiten Platte 21 bzw. 22 zur Platte 12 bzw. 13 ist insbesondere bei Montagearbeiten das Risiko gering, dass die erfindungsgemässen Vorrichtungen ,,verkehrt" im entsprechenden Bauteil angeordnet werden, was insbesondere bei den vorhergehenden Ausführungsbeispielen erfolgen könnte, wodurch natürlich deren angestrebte Wirkungsweise verloren gehen würde.Due to the symmetrical arrangement of a second plate 21 or 22 relative to plate 12 or 13, the risk is low, in particular during assembly work, that the devices according to the invention are arranged "wrongly" in the corresponding component, which could be done in particular in the previous exemplary embodiments, which of course means the desired mode of action would be lost.

Wie insbesondere auch aus Fig. 9 ersichtlich ist, weisen die Platte 12 und 13 und die zweiten Platten 21 und 22 an den seitlichen Rändern jeweils eine Ausnehmung 24 auf, die von der entsprechenden flanschförmigen Scheibe 8 bzw. 9 jeweils den gleich grossen Abstand aufweisen. In diese Ausnehmungen 24 kommen jeweils die Grundstege 25 eines Verankerungsbügels 26 zu liegen, wobei diese durch Klemmwirkung gehalten sind und im einbetonierten Zustand eine feste Verbindung entsteht.As can also be seen in particular from FIG. 9, the plates 12 and 13 and the second plates 21 and 22 each have a recess 24 on the lateral edges, which are each at the same distance from the corresponding flange-shaped disc 8 and 9, respectively. The base webs 25 of an anchoring bracket 26 each come to lie in these recesses 24, these being held by a clamping action and a solid connection being produced in the concreted-in state.

Beim Erstellen von Bauteilen aus Beton werden die Hülsenelemente an den entsprechenden Schalungswänden befestigt. Hierzu ist an der flanschartigen Scheibe 9 eine Befestigungseinrichtung 27 angebracht, die in Form eines Flachprofils ausgebildet ist, das mit Löchern, beispielsweise zur Befestigung an der Schalungswand mit Nägeln ausgestattet ist. Die vordere und die hintere Oeffnung der Hülse 6 können durch Abdeckungen verschlossen werden, damit vermieden wird, dass Beton bzw. Zementmilch in den Innenteil der Hülse gelangt. Danach kann der Bauteil 2 betoniert werden. Nach dem Abbinden des Betons erfolgt das Ausschalen des Bauteils 2. Der angrenzende Bauteil 1 wird in einer nachfolgenden Etappe erstellt. Dabei werden nach dem Schalen die zugehörigen Dorne 5 der Dornelemente in die einbetonierten Hülsen 6 der Hülsenelemente gesteckt, wozu die entsprechenden Abdeckungen der Hülse abgenommen werden. Gleichzeitig wird in der Regel die Fugenisolation erstellt, wonach das Verlegen der Bewehrung und das Betonieren des Bauteils 1 erfolgt.When creating components from concrete, the sleeve elements are attached to the corresponding formwork walls. For this purpose, a fastening device 27 is attached to the flange-like disc 9, which is designed in the form of a flat profile which is equipped with holes, for example for fastening to the formwork wall with nails. The front and the rear opening of the sleeve 6 can be closed by covers in order to avoid that concrete or cement milk gets into the inner part of the sleeve. The component 2 can then be concreted. After this Setting of the concrete is carried out by striking the component 2. The adjacent component 1 is created in a subsequent stage. After forming, the associated mandrels 5 of the mandrel elements are inserted into the concreted-in sleeves 6 of the sleeve elements, for which purpose the corresponding covers of the sleeve are removed. At the same time, the joint insulation is usually created, after which the reinforcement is laid and the component 1 is concreted.

Damit während des Betonierens in den Dornelementen bzw. den Hülsenelementen keine Luft eingeschlossen wird, können in den Platten 12 und 13 und in den zweiten Platten 21 und 22 Oeffnungen 28 vorgesehen sein.So that no air is trapped in the mandrel elements or sleeve elements during concreting, openings 28 can be provided in the plates 12 and 13 and in the second plates 21 and 22.

Je nach Anwendung können, wie bereits vorgängig beschrieben wurde, die Dornelemente und die Hülsenelemente entsprechend dimensioniert sein. Dies bezieht sich ebenfalls auf die flanschartigen Scheiben und die Platten. Dorn und Hülse können praktisch einen beliebigen übereinstimmenden Querschnitt aufweisen, der Dorn kann einen Hohlquerschnitt aufweisen oder einen hybriden Querschnitt aus mehreren Werkstoffen aufweisen. Die Materialwahl erfolgt ebenfalls in Abhängigkeit der Anwendung, wobei in vorteilhafter Weise korrosionsbeständige Stähle verwendet werden.Depending on the application, as already described above, the mandrel elements and the sleeve elements can be dimensioned accordingly. This also applies to the flange-like disks and the plates. The mandrel and the sleeve can practically have any matching cross-section, the mandrel can have a hollow cross-section or a hybrid cross-section made of several materials. The choice of material also depends on the application, with corrosion-resistant steels being used in an advantageous manner.

Mit dieser erfindungsgemässen Vorrichtung kann eine sichere Verbindung und Aufnahme von Querkräften von zwei Bauteilen erreicht werden. Hierbei können, wegen der günstigen Krafteinleitung, die Bauteile eine geringere Dicke aufweisen, insbesondere kann die Platte 12 bzw. 13 jeweils sehr nahe an der Oberfläche des entsprechenden Bauteils angeordnet sein. Wegen der grösseren Bruchsicherheit des Betons kann auch die Anzahl der erfindungsgemässen Vorrichtungen reduziert werden.With this device according to the invention, a secure connection and absorption of transverse forces from two components can be achieved. Because of the favorable introduction of force, the components can have a smaller thickness, in particular the plate 12 or 13 can be arranged very close to the surface of the corresponding component. Because of the greater break resistance of the concrete, the number of devices according to the invention can also be reduced.
