Description

Die vorliegende Erfindung bezieht sich auf eine Vorrichtung zum Verbinden von zwei durch eine Fuge getrennten Bauteilen, insbesondere aus Beton, die zur Aufnahme von in einer Richtung und/oder ihrer Gegenrichtung wirkenden Querkräfte geeignet ist, umfassend einen Dorn, dessen einer Bereich im ersten Bauteil einsetzbar ist, und eine Hülse, die im zweiten Bauteil einsetzbar ist, und die der Aufnahme des anderen Bereichs des Dorns dient, mit am Dorn und an der Hülse angebrachten Verstärkungselementen, die jeweils eine gegen die Fuge gerichtete erste Platte aufweisen, an welcher an einander gegenüberliegenden Seiten Bügelbereiche angebracht sind, die sich von der Fuge weg erstrecken, und die erste Platte eine Öffnung aufweist, durch welche jeweils der Dorn bzw. die Hülse hindurch geführt ist, und der Raum zwischen der ersten Platte und den Bügelbereichen durch eine Füllmasse ausgefüllt ist.The present invention relates to a device for connecting two components separated by a joint, in particular of concrete, which is suitable for receiving transverse forces acting in one direction and / or in the opposite direction, comprising a mandrel whose one region can be inserted in the first component is, and a sleeve which is insertable in the second member, and which serves to receive the other portion of the mandrel, with reinforcing elements mounted on the mandrel and on the sleeve, each having a facing against the joint first plate, on which at opposite Side bracket portions are mounted, which extend away from the joint, and the first plate has an opening through which each of the mandrel and the sleeve is guided, and the space between the first plate and the strap portions is filled by a filling material.

Wenn im Hoch- und Tiefbau Bauteile wie Dachplatten, Bodenplatten, Decken, Wände, Stützmauern und so weiter miteinander verbunden werden sollen, ist es erforderlich, zwischen den miteinander zu verbindenden Bauteilen Fugen vorzusehen. Diese Bauteile bestehen üblicherweise aus Beton, es können aber auch andere entsprechende geeignete Materialien eingesetzt werden. Diese Fugen sind erforderlich, damit Dehnungen der Bauteile bei Temperaturschwankungen sowie Schwind- und Kriecheinflüssen ausgeglichen werden können. Gleichzeitig sollen diese Bauteile aber derart miteinander verbunden werden, dass Querkräfte vom einen Bauteil auf den anderen übertragen werden können, ohne die oben beschriebenen Dehnungen zu beeinträchtigen. Hierbei werden vielfach Dorn-Hülsen-Verbindungen gewählt, der Dornteil wird in einem ersten Bauteil so angeordnet, dass der eine Endbereich des Dorns aus dem betreffenden Bauteil vorsteht, dieser vorstehende Endbereich des Dorns dringt in eine Hülse ein, die im anderen Bauteil angeordnet ist. Über diese Dorn-Hülsen-Verbindung können die zwischen dem Bauteilen auftretenden Querkräfte optimal übertragen werden, der Dorn ist in der Hülse längsverschiebbar gehalten, wodurch die Dehnungen der Bauteile ausgeglichen werden können. Die Hülse
kann auch in bekannter Weise so ausgebildet sein, dass auch geringe seitliche Verschiebungen des Dornes in der Hülse ermöglicht werden.If in civil engineering components such as roof panels, floor panels, ceilings, walls, retaining walls and so on are to be connected to each other, it is necessary to provide joints between the components to be joined. These components are usually made of concrete, but other appropriate suitable materials can be used. These joints are required so that expansions of the components can be compensated for temperature fluctuations and shrinkage and creep. At the same time, however, these components should be connected to one another in such a way that lateral forces can be transmitted from one component to the other without impairing the expansions described above. In this case, multiple mandrel-sleeve connections are selected, the mandrel part is arranged in a first component so that the one end region of the mandrel protrudes from the relevant component, this protruding end portion of the mandrel penetrates into a sleeve which is arranged in the other component. About this mandrel-sleeve connection occurring between the components transverse forces can be optimally transmitted, the mandrel is held longitudinally displaceable in the sleeve, whereby the expansions of the components can be compensated. The sleeve
can also be designed in a known manner so that even small lateral displacements of the mandrel are made possible in the sleeve.

Bei derartigen Verbindungen von Bauteilen wirken insbesondere am Fugenrand hohe Belastungen auf die Dorn-Hülse-Verbindung. Entsprechend wird der den Dorn und die Hülse in diesen Bereichen umgebende Beton ebenfalls sehr stark belastet. Um zu vermeiden, dass in diesen Bereichen, die die höchsten Belastungspitzen aufweisen, der Beton am Fugenrand ausbrechen kann, sind der Dorn und die Hülse in diesem Bereich jeweils mit einer Platte ausgestattet, die zusätzlich mit in die Bauteile hineinragenden Bügelbereichen versehen sind. Mit diesen vorzugsweise aus Stahl ausgebildeten Platten mit Bügelbereichen soll erreicht werden, dass die auf den Bauteil zu übertragenden Kräfte möglichst verteilt über einen grösseren Bereich des Betons verteilt werden. Entsprechend wird erreicht, dass der Bruchwiderstand des Betons in diesem Bereich verbessert werden kann. Eine derartige Vorrichtung ist beispielsweise dem Dokument EP 0 773 324 B1 entnehmbar. Um zu vermeiden, dass derartige Vorrichtungen korrodieren können, müssen diese aus nicht rostenden Materialien hergestellt werden. Derartige Materialien haben einen entsprechenden höheren Preis.In such compounds of components act particularly at the joint edge high loads on the mandrel-sleeve connection. Accordingly, the concrete surrounding the mandrel and the sleeve in these areas is also very heavily loaded. In order to avoid that in these areas, which have the highest load peaks, the concrete can break out at the joint edge, the mandrel and the sleeve in this area are each equipped with a plate, which are additionally provided with projecting into the components bracket areas. With these preferably made of steel plates with ironing areas to be achieved that the forces to be transmitted to the component distributed as possible over a larger area of the concrete to be distributed. Accordingly, it is achieved that the fracture resistance of the concrete in this area can be improved. Such a device is for example the document EP 0 773 324 B1 removable. To prevent such devices from corroding, they must be made of stainless materials. Such materials have a corresponding higher price.

Die Aufgabe der vorliegenden Erfindung besteht nun darin, eine Vorrichtung zum Verbinden von zwei durch eine Fuge getrennten Bauteilen zu schaffen, bei welchen die Materialkosten möglichst gering gehalten werden können, und welche eine optimale Halterung in den entsprechenden Bauteilen und eine optimale Kraftübertragung auf die entsprechenden Bauteile und umgekehrt ermöglichen.The object of the present invention is therefore to provide a device for connecting two components separated by a joint, in which the material costs can be kept as low as possible, and which optimal support in the corresponding components and optimal power transmission to the corresponding components and vice versa.

Erfindungsgemäss erfolgt die Lösung dieser Aufgabe dadurch, dass mindestens die beiden Seitenflächen der Füllmasse, die durch die erste Platte und die Bügelbereiche begrenzt sind, mit Vorsprüngen und Vertiefungen versehen sind, die in die Füllmasse eingeformt sind und dass die Füllmasse (7) eine hochfeste mörtelartige Masse ist.According to the invention, the solution of this object is achieved in that at least the two side surfaces of the filling material, which are bounded by the first plate and the strap portions are provided with projections and depressions, which are molded into the filling compound and that the filling compound (7) is a high-strength mortar-like Mass is.

Durch das Anbringen von Vorsprüngen und Vertiefungen mindestens an den beiden Seitenflächen der Füllmasse wird eine optimale Verankerung dieser so gebildeten Verstärkungselemente im entsprechenden Bauteil erreicht. Die Übertragung der Querkräfte vom Dorn bzw. der Hülse auf den entsprechenden Bauteil bzw. umgekehrt kann dadurch in optimaler Weise unterstützt werden. Durch die entsprechende Ausgestaltung der Verstärkungselemente am Dorn und an der Hülse kann die erste Platte eine geringere Dicke aufweisen, entsprechend können die Bügelbereiche eine geringere Dicke aufweisen, wodurch Material eingespart und die Materialkosten reduziert werden können. Indem die Füllmasse eine hochfeste mörtelartige Masse ist, kann einerseits die gewünschte Festigkeit erreicht werden, andererseits kann diese mörtelartige Masse in entsprechend um den Dorn bzw. die Hülse angelegte Formen eingegossen werden und danach aushärten.By attaching projections and depressions at least on the two side surfaces of the filling compound is an optimal anchorage achieved this reinforcing elements formed in the corresponding component. The transmission of the transverse forces from the mandrel or the sleeve to the corresponding component or vice versa can thereby be optimally supported. Due to the corresponding design of the reinforcing elements on the mandrel and on the sleeve, the first plate may have a smaller thickness, accordingly, the ironing regions may have a smaller thickness, whereby material can be saved and the material costs can be reduced. By the filling material is a high-strength mortar-like mass, on the one hand, the desired strength can be achieved, on the other hand, this mortar-like mass can be poured into correspondingly applied around the mandrel or the sleeve shapes and then cure.

In vorteilhafter Weise weisen die Seitenflächen der Füllmasse eine konkave Wölbung auf. Damit wird erreicht, dass die Verankerung im Material der Bauteile zusätzlich verbessert wird, durch die konkaven Wölbungen erhält man zusätzlich eine formschlüssige Verbindung der Verstärkungselemente mit den Bauteilen.Advantageously, the side surfaces of the filling compound on a concave curvature. This ensures that the anchoring in the material of the components is additionally improved by the concave curvatures obtained in addition a positive connection of the reinforcing elements with the components.

In vorteilhafter Weise sind die Vorsprünge und Vertiefungen als Rippen und Rillen ausgebildet, die im Wesentlichen parallel zu den Bügelbereichen verlaufen. Mit diesen Rippen und Rillen wird die Übertragung der Querkräfte vom Dorn und Hülse auf die Bauteile und umgekehrt zusätzlich verbessert, die die Kräfte aufnehmenden Flächenbereiche werden vergrössert.Advantageously, the projections and recesses are formed as ribs and grooves which extend substantially parallel to the strap portions. With these ribs and grooves, the transmission of transverse forces from the mandrel and sleeve on the components and vice versa is additionally improved, the forces receiving surface areas are increased.

In vorteilhafter Weise weisen die Rippen und Rillen einen dreieckförmigen Querschnitt auf, die Kräfteübertragung wird dadurch optimal.Advantageously, the ribs and grooves have a triangular cross-section, the transmission of forces is thereby optimal.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass der Scheitelwinkel der dreieckförmigen Querschnitte der Rippen und Rillen etwa 60° bis 120° beträgt. Hierdurch werden die die Kraft aufnehmenden Flächen der Rippen und Rillen eine optimale Neigung aufweisen, um die Querkräfte möglichst gut aufnehmen zu können.A further advantageous embodiment of the invention is that the apex angle of the triangular cross-sections of the ribs and grooves is about 60 ° to 120 °. As a result, the force-receiving surfaces of the ribs and grooves will have an optimal inclination to absorb the lateral forces as well as possible.

In vorteilhafter Weise ist der Scheitelwinkel der dreieckförmigen Querschnitte der Rippen und Rillen einer Seitenfläche unterschiedlich gross, wodurch auch Querkräfte, die unterschiedliche Richtungen aufweisen können, optimal aufgenommen werden können.Advantageously, the vertex angle of the triangular cross-sections of the ribs and grooves of a side surface is different in size, whereby also transverse forces, which may have different directions, can be optimally absorbed.

In vorteilhafter Weise sind die der ersten Platte abgewandten Endbereiche der Bügelbereiche mit Umbiegungen versehen, wodurch eine optimale Verbindung zwischen Platte und Bügelbereiche und der eingeschlossenen Füllmasse erreicht wird.Advantageously, the first plate facing away from the end portions of the strap portions are provided with bends, whereby an optimum connection between the plate and strap portions and the enclosed filling material is achieved.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass die zwischen den beiden Umbiegungen durch die Füllmasse gebildete Rückfläche ebenfalls mit Vorsprüngen und Vertiefungen versehen ist und die Rückfläche ebenfalls eine konkave Wölbung aufweist. Hierdurch wird die Verankerung des Verstärkungselements im Bauteil zusätzlich verbessert.A further advantageous embodiment of the invention is that the rear surface formed by the filler between the two bends is also provided with projections and depressions and the rear surface also has a concave curvature. As a result, the anchoring of the reinforcing element in the component is additionally improved.

Eine weitere vorteilhafte Ausgestaltung der Erfindung besteht darin, dass die Endbereiche der einander gegenüberliegenden Umbiegungen aneinander stossen und miteinander verbunden sind und den Dorn bzw. die Hülse umschliessen. Hierdurch wird erreicht, dass die Füllmasse optimal umschlossen ist.A further advantageous embodiment of the invention is that the end portions of the opposing bends abut each other and are connected to each other and enclose the mandrel or the sleeve. This ensures that the filling material is optimally enclosed.

Die Endbereiche der einander gegenüberliegenden Umbiegungen können einander auch überlappen und mit Durchbrüchen versehen sein, durch welche der Dorn bzw. die Hülse hindurchragen, dadurch wird es nicht erforderlich, die Umbiegungen zusätzlich miteinander zu verbinden.The end portions of the opposing bends may also overlap each other and be provided with openings through which the mandrel or the sleeve protrude, thereby it is not necessary to additionally connect the bends with each other.

In vorteilhafter Weise sind in die Bügelbereiche Spannbolzen eingesetzt, welche die beiden Bügelbereiche und die Füllmasse durchdringen und dadurch eine Verstärkung erreicht werden kann.Advantageously, clamping bolts are used in the ironing areas, which penetrate the two ironing areas and the filling compound and thus gain can be achieved.

These ribs 12 and grooves 13 may, for example, have a triangular cross-section, this triangular-shaped cross-section may be of different size, other shapes may also be used, as will be described later.

Die zwischen den Umbiegungen 6 der beiden Bügelbereiche 5 bestehende Rückfläche 14 der Füllmasse 7 kann ebenfalls eine konkave Wölbung 9 aufweisen, auch hier können Vorsprünge 10 und Vertiefungen 11 vorgesehen sein, die in vorteilhafter Weise der Form der Vorsprünge 10 und Vertiefungen 11 der Seitenflächen 8 entsprechen.The existing between the bends 6 of the two bracket portions 5 back surface 14 of the filling material 7 may also have a concave curvature 9, also here projections 10 and recesses 11 may be provided, which correspond advantageously to the shape of the projections 10 and recesses 11 of the side surfaces 8 ,

In die Verstärkungselemente 3 können zusätzlich noch Spannbolzen 16 eingesetzt werden, welche jeweils die Bügelbereiche 5 und die Füllmasse 7 durchdringen, die später noch im Detail beschrieben werden.In the reinforcing elements 3 clamping bolts 16 can additionally be used, which respectively penetrate the bracket portions 5 and the filling compound 7, which will be described later in detail.

In bekannter, nicht dargestellter Weise werden die so ausgebildeten Dorne 1 und Hülsen 2 in die miteinander zu verbindenden Bauteile eingesetzt. Hierbei wird die jeweilige Hülse 2 an der Verschalung des einen zu bildenden Bauteils befestigt, wozu an der ersten Platte 4 Nagellöcher 15 vorgesehen sind. Dieser Bauteil wird dann ausbetoniert, nach dem Aushärten wird die Verschalung entfernt, danach wird der zweite Bauteil erstellt, hierzu werden in die Hülsen 2 die Dorne 1 eingeschoben, der entsprechende Bauteil wird dann ebenfalls ausbetoniert, dadurch erhält man über die Dorne und die Hülsen eine optimale Verbindung der beiden Bauteile. Die ersten Platten 4 sind in den entsprechenden Bauteilen jeweils bündig an den die Fuge bildenden Flächen angeordnet.In a known, not shown manner, the thus formed mandrels 1 and 2 sleeves are inserted into the components to be joined together. Here, the respective sleeve 2 is attached to the casing of a component to be formed, for which purpose nail holes 15 are provided on the first plate. This component is then concreted, after curing, the casing is removed, then the second component is created for this purpose, the mandrels 1 are inserted into the sleeves 2, the corresponding component is then also concreted, thereby obtained on the mandrels and the sleeves one optimal connection of the two components. The first plates 4 are arranged in the respective components in each case flush with the surfaces forming the joint.

Um eine lange Lebensdauer von Dorn und Hülse erreichen zu können, sind diese sowie die entsprechenden Teile der Verstärkungselemente aus einem korrosionsbeständigen Material gebildet, beispielsweise nicht rostender Stahl, selbstverständlich können aber auch andere geeignete Materialien eingesetzt werden.In order to achieve a long life of mandrel and sleeve, these and the corresponding parts of the reinforcing elements are formed of a corrosion-resistant material, such as stainless steel, but of course other suitable materials can be used.

Die in Figur 2 dargestellte zweite Ausführungsform der erfindungsgemässen Vorrichtung zum Verbinden von zwei durch eine Fuge getrennten Bauteilen ist identisch aufgebaut, wie die in Figur 1 dargestellte erste Ausführungsform, der einzige Unterschied besteht darin, dass die Rippen 12 und Rillen 13 in dieser zweiten Ausführungsform einen grösseren dreieckförmigen Querschnitt aufweisen, als diejenigen in der ersten Ausführungsform. Zusätzlich ist der Scheitelwinkel dieser dreieckförmigen Querschnittform, wie später noch im Detail beschrieben wird, ebenfalls grösser.In the FIG. 2 illustrated second embodiment of the inventive device for connecting two components separated by a joint is constructed identically, as in FIG. 1 illustrated first embodiment, the only difference is that the ribs 12 and grooves 13 in this second embodiment have a larger triangular cross-section than those in the first embodiment. In addition, the apex angle of this triangular cross-sectional shape, as described later in detail, is also larger.

Aus Figur 3 ist eine dritte Ausführungsform der erfindungsgemässen Vorrichtung zum Verbinden von zwei durch eine Fuge getrennten Bauteile ersichtlich, bei welchen die dreieckförmige Querschnittform der Rippen und Rillen gegenüber der in Figur 2 dargestellten zweiten Ausführungsform eine grössere Höhe aufweisen. Zudem ist hier auch die Rückfläche 14 des Dornes 1 ersichtlich, die in identischer Weise ausgebildet ist, wie die Rückfläche 14 der Hülse 2.Out FIG. 3 is a third embodiment of the inventive device for connecting two separated by a joint components visible, in which the triangular cross-sectional shape of the ribs and grooves relative to the in FIG. 2 illustrated second embodiment have a greater height. In addition, here the rear surface 14 of the mandrel 1 can be seen, which is formed in an identical manner, as the rear surface 14 of the sleeve. 2

Die Figuren 4 und 5 zeigen eine Seitenansicht bzw. eine Ansicht von oben auf die dritte Ausführungsform der erfindungsgemässen Vorrichtung zum Verbinden von zwei durch eine Fuge getrennten Bauteilen, wie sie in Figur 3 dargestellt ist. Hierbei ist insbesondere ersichtlich, wie die Spannbolzen 16 in die Verstärkungselemente 3 eingesetzt sind. Diese Spannbolzen 16 durchdringen jeweils die Bügelbereiche 5 und Füllmasse 7, diese Spannbolzen 16 verhindern, dass die Bügelbereiche 5 gegebenenfalls auseinander gespreizt werden könnten, wodurch der Widerstand dieser Verstärkungselemente 3 verbessert werden kann. In einfacher Weise können diese Spannbolzen 16 durch eine Sechskantschraube mit aufgesetzter Mutter gebildet sein, was eine besonders kostengünstige Lösung ergibt. Ebenfalls ersichtlich aus diesen beiden Figuren ist, dass jeweils in der ersten Platte 4 von Dorn 1 und Hülse 2 eine Öffnung 18 angebracht ist, durch welche der Dorn 1 bzw. die Hülse 2 hindurchragen und in welchen Öffnungen der Dorn1 bzw. die Hülse 2 befestigt sind, beispielsweise durch Verschweissung.The FIGS. 4 and 5 show a side view and a top view of the third embodiment of the inventive device for connecting two separated by a joint components, as shown in FIG FIG. 3 is shown. It can be seen in particular how the clamping bolts 16 are inserted into the reinforcing elements 3. These clamping bolts 16 respectively penetrate the ironing regions 5 and filling compound 7, these clamping bolts 16 prevent the ironing regions 5 from possibly being spread apart, as a result of which the resistance of these reinforcing elements 3 can be improved. In a simple way, these clamping bolts 16 may be formed by a hexagon bolt with attached nut, resulting in a particularly cost-effective solution. Also apparent from these two figures is that in each case in the first plate 4 of the mandrel 1 and sleeve 2, an opening 18 is mounted, through which protrude the mandrel 1 and the sleeve 2 and in which openings the Dorn1 and the sleeve 2 attached are, for example, by welding.

Figur 6 zeigt eine andere Ausführungsform eines Verstärkungselementes 3, das hier auf eine Hülse 2 aufgesetzt ist, selbstverständlich könnte dieses Verstärkungselement 3 auch auf einen Dorn aufgesetzt werden. Dieses Verstärkungselement 3 umfasst wiederum eine erste Platte 4, die mit den entsprechenden Bügelbereichen 5 ausgestattet ist. Die Umbiegungen 6 weisen eine grössere Länge auf, sodass sie aneinander stossen. Die aneinander stossenden Bereiche dieser Umbiegungen 6 sind miteinander verbunden, beispielsweise durch eine Verschweissung. In den durch die erste Platte, die Bügelbereiche und die Umbiegungen gebildeten Raum ist wiederum die Füllmasse 7 eingebracht, die Seitenflächen 8 dieser Füllmasse 7 sind in gleicher Weise ausgebildet, wie die Seitenfläche der vorgängig beschriebenen Ausführungsformen der erfindungsgemässen Vorrichtung. Die erste Platte 4, die Bügelbereiche 5 und die Umbiegungen 6 bilden somit eine geschlossene Schlaufe, wodurch eine optimale Festigkeit des so gebildeten Verstärkungselementes 3 erreicht werden kann. Die in Figur 6 dargestellten Spannbolzen 16 könnten weggelassen werden. FIG. 6 shows another embodiment of a reinforcing element 3, which is placed here on a sleeve 2, of course, this reinforcing element 3 could also be placed on a mandrel. This reinforcing element 3 in turn comprises a first plate 4, which is equipped with the corresponding bracket portions 5. The bends 6 have a greater length, so they collide. The abutting areas of these bends 6 are connected to each other, for example by a weld. The filling compound 7 is in turn introduced into the space formed by the first plate, the stirrup regions and the bends, the side surfaces 8 of this filling compound 7 are formed in the same way as the side surface of the previously described embodiments of the device according to the invention. The first plate 4, the bracket portions 5 and the bends 6 thus form a closed loop, whereby an optimal strength of the reinforcing element 3 thus formed can be achieved. In the FIG. 6 illustrated clamping bolt 16 could be omitted.

Figur 7 zeigt wiederum ein Verstärkungselement 3, das auf eine Hülse 2 aufgesetzt ist, welches aber selbstverständlich auch auf einen Dorn 1 aufgesetzt werden könnte. Dieses Verstärkungselement 3 ist gleich aufgebaut, wie die Ausführungsform, die in Figur 6 beschrieben worden ist, der Unterschied besteht darin, dass die Umbiegungen 6 eine grössere Länge aufweisen, sodass sie einander überlappen. Die Verbindung dieser beiden Umbiegungen 6 wird durch die Hülse 2 erreicht, die durch entsprechend in den überlappenden Bereichen der Umbiegungen 6 angebrachten Öffnungen 7 fixiert sind. Somit erhält man auch hier im Prinzip eine durch die erste Platte 4, die beiden Bügelbereiche 5 und die einander überlappenden Umbiegungen 6 eine geschlossene Schlaufe mit den bereits zu Figur 6 erwähnten Vorteilen. FIG. 7 again shows a reinforcing element 3, which is placed on a sleeve 2, but which of course also on a mandrel. 1 could be put on. This reinforcing element 3 has the same structure as the embodiment shown in FIG FIG. 6 has been described, the difference is that the bends 6 have a greater length, so that they overlap each other. The connection of these two bends 6 is achieved by the sleeve 2, which are fixed by correspondingly mounted in the overlapping areas of the bends 6 openings 7. Thus, one obtains in this case, in principle, by the first plate 4, the two strap portions 5 and the overlapping bends 6 a closed loop with the already to FIG. 6 mentioned advantages.

In den Figuren 8 bis 11 ist jeweils ein Verstärkungselement 3 dargestellt, das auf eine Hülse 2 aufgesetzt ist. Selbstverständlich könnten diese Verstärkungselemente 3 auch auf einen Dorn aufgesetzt werden. Diese Verstärkungselemente 3 weisen, wie vorgängig beschrieben worden ist, eine Füllmasse 7 auf, durch welche die Seitenflächen 8 gebildet werden. Wie bereits vorgängig beschrieben worden ist, sind diese Seitenflächen 8 beispielsweise mit Rippen 12 und Rillen 13 ausgestattet.In the FIGS. 8 to 11 In each case, a reinforcing element 3 is shown, which is placed on a sleeve 2. Of course, these reinforcing elements 3 could also be placed on a mandrel. These reinforcing elements 3, as has been described previously, a filling compound 7, through which the side surfaces 8 are formed. As has already been described above, these side surfaces 8 are equipped, for example, with ribs 12 and grooves 13.

Figur 8 zeigt Rippen 12, die einen dreieckförmigen Querschnitt aufweisen. Der Scheitelwinkel α dieser dreieckförmigen Querschnitte beträgt hier etwa 60°, die Seitenflächen 8 weisen eine relativ geringe konkave Wölbung 9 auf. FIG. 8 shows ribs 12 which have a triangular cross-section. The apex angle α of this triangular cross-sections is here about 60 °, the side surfaces 8 have a relatively small concave curvature 9.

In Figur 9 weisen die Rippen 12 ebenfalls einen dreieckförmigen Querschnitt auf, im Gegensatz zum in Figur 8 dargestellten Beispiel sind diese Rippen kleiner ausgebildet, der Scheitelwinkel α beträgt ebenfalls etwa 60°, die Seitenflächen 8 weisen eine grössere konkave Wölbung 9 auf, als im Beispiel gemäss Figur 8.In FIG. 9 The ribs 12 also have a triangular cross section, in contrast to in FIG. 8 illustrated example, these ribs are formed smaller, the apex angle α is also about 60 °, the side surfaces 8 have a larger concave curvature 9, as in the example according to FIG. 8 ,

Im Beispiel gemäss Figur 10 weisen die Rippen 12 ebenfalls einen dreieckförmigen Querschnitt auf, der Scheitelwinkel α beträgt hier aber etwa 90°. Die Seitenflächen 8 weisen eine relativ grosse konkave Wölbung 9 auf.In the example according to FIG. 10 the ribs 12 also have a triangular cross-section, the apex angle α is here but about 90 °. The side surfaces 8 have a relatively large concave curvature 9.

Figur 11 zeigt ein Beispiel, bei welchen die Rippen 12 eine gewölbte Oberfläche aufweisen. Die Seitenflächen 8 weisen wiederum eine relativ grosse konkave Wölbung 9 auf. FIG. 11 shows an example in which the ribs 12 have a curved surface. The side surfaces 8 in turn have a relatively large concave curvature 9.

Bei den in Figur 8 bis Figur 11 dargestellten Beispielen zur Ausgestaltung der Rippen und Rillen sind die jeweiligen Rückflächen entsprechend den Seitenflächen ausgebildet. Selbstverständlich muss dies aber nicht zwingend der Fall sein.At the in FIG. 8 to FIG. 11 Examples shown for the design of the ribs and grooves, the respective rear surfaces are formed corresponding to the side surfaces. Of course, this does not necessarily have to be the case.

In den in Figur 8 bis Figur 11 gezeigten Beispielen zur Ausgestaltung der Rippen und Rillen weisen die Rippen über die gesamten Seitenflächen und Rückflächen jeweils eine identische Form und Grösse auf. Dies muss aber nicht so sein, beispielsweise können über die Seitenflächen 8 und die jeweilige Rückfläche Rippen mit unterschiedlichen Querschnittformen und gegebenenfalls unterschiedlichen Scheitelwinkeln eingesetzt werden.In the in FIG. 8 to FIG. 11 As shown in the examples of the embodiment of the ribs and grooves, the ribs have an identical shape and size over the entire side surfaces and rear surfaces. However, this need not be so, for example, ribs with different cross-sectional shapes and optionally different vertex angles can be used over the side surfaces 8 and the respective rear surface.

Durch die Vorsprünge und Vertiefungen, die an den durch die Füllmasse gebildeten Seitenflächen und gegebenenfalls der Rückfläche des Verstärkungselementes angebracht sind, wird eine optimale Verankerung dieser Verstärkungselemente in den jeweiligen Bauteilen erhalten. Ein Teil der wirksamen Querkräfte können durch die Flächenbereiche, die durch die Flanken der Vorsprünge und Vertiefungen gebildet werden, in optimaler Weise übertragen werden, besonders optimal ist diese Übertragung bei den Ausführungsbeispielen, bei denen die Vorsprünge als Rippen und die Vertiefungen als Rillen ausgebildet sind. Selbstverständlich wird ein Hauptteil der wirksamen Querkräfte über die Bügelbereiche übertragen. Eine zusätzliche Verbesserung der Verankerung und der Übertragung der Kräfte wird durch das Anbringen von konkaven Wölbungen der Seitenflächen und gegebenenfalls der Rückfläche erhalten. Die Grösse der Vorsprünge und Vertiefungen, die Winkel, die die entsprechenden Flächen der Flanken aufweisen, die Formgebung der Vorsprünge und Vertiefungen und die Wahl der Stärke der konkaven Wölbungen der Seitenflächen und gegebenenfalls der Rückfläche können in optimaler Weise an die Einsatzart und beispielsweise an das Material, aus welchem die Bauteile gebildet werden, angepasst werden.By the projections and depressions, which are attached to the side surfaces formed by the filling compound and optionally the rear surface of the reinforcing element, an optimal anchoring of these reinforcing elements is obtained in the respective components. A portion of the effective lateral forces can be transmitted in an optimum manner by the surface regions which are formed by the flanks of the projections and depressions, this transfer is particularly optimal in the embodiments in which the projections are formed as ribs and the depressions as grooves. Of course, a majority of the effective transverse forces will be transmitted through the strap sections. An additional improvement in the anchoring and the transmission of forces is obtained by the attachment of concave curvatures of the side surfaces and optionally the back surface. The size of the projections and depressions, the angles that have the corresponding surfaces of the flanks, the shape of the projections and depressions and the choice of the strength of the concave curvatures of the side surfaces and optionally the back surface can optimally on the Einsatzart and for example on the material , from which the components are formed, to be adapted.

Durch die Verbundbauweise der Verstärkungselemente und die optimale Ausgestaltung der Form und dadurch der optimalen Kraftübertragung kann die Dicke der ersten Platte und der Bügelbereiche sowie der Umbiegungen minimal gehalten werden, sodass hier Einsparungen an Material erreicht werden können, was sich insbesondere bei der Verwendung von nicht rostendem Stahl entsprechend auf den Preis auswirkt.Due to the composite construction of the reinforcing elements and the optimum design of the shape and thus the optimal power transmission, the thickness of the first plate and the strap portions and the bends can be kept to a minimum, so here savings of material can be achieved, which is particularly in the use of stainless Steel accordingly affects the price.
