Description

Die Erfindung betrifft eine Verankerungseinrichtung zum Stabilisieren von Bewegungen im Gelände, im Fels oder im Lockergestein, in Bauwerken und dgl. gemäss Oberbegriff des Anspruches 1.The invention relates to an anchoring device for stabilizing movements in terrain, in rock or in loose rock, in structures and the like. According to the preamble of claim 1.

In der EP-A-1 564 369 und der entsprechenden US-A-2005/0191138 (Fig. 12) ist eine Verankerungseinrichtung dieser Art gezeigt und beschrieben, die als Felsanker zum Stabilisieren eines ausgebrochenen Tunnels ausgebildet ist. Der Ankerstab diese Felsankers ist am einen Ende im Fels oder im Lockergestein verankert. Am andern Ende wirkt der Ankerstab auf eine erste Stahlscheibe ein, die auf einem Stauchkörper aus einem kompressiblen Material aufliegt und als Kraftübertragungselement dient. Der Stauchkörper enthält in ein Bindemittel eingebettete, bei einer bestimmten Druckbelastung zusammendrückbare Partikel sowie Verstärkungselemente und stützt sich über eine zweite Stahlscheibe an der Wand des Tunnels ab. Auf den, den Stauchkörper durchdringenden Ankerstab wirkende Zugkräfte werden über die erste Stahlscheibe auf den Stauchkörper übertragen. Überschreitet dabei die auf den Stauchkörper einwirkende Druckbelastung einen bestimmten Wert, so wird der Stauchkörper verformt. Der zylindrische Stauchkörper und die ebenfalls zylindrische erste Stahlscheibe haben denselben Durchmesser. Das bedeutet ,dass die Auflagefläche, mit der die erste Stahlscheibe auf der Stirnfläche des Stauchkörpers aufliegt, gleich gross ist wie die Stirnfläche des Stauchkörpers.In the EP-A-1 564 369 and the corresponding US-A-2005/0191138 (Figure 12) there is shown and described an anchoring device of this type, which is designed as a rock bolt for stabilizing a broken tunnel. The anchor rod of this rock anchor is anchored at one end in the rock or in loose rock. At the other end of the anchor rod acts on a first steel disc, which rests on a compression body made of a compressible material and serves as a power transmission element. The compression body contains embedded in a binder, compressible under a certain pressure load particles and reinforcing elements and is supported by a second steel disc on the wall of the tunnel. Tensile forces acting on the upset body of the anchorage rod are transferred to the compression body via the first steel disc. If the pressure load acting on the compression body exceeds a certain value, then the compression body is deformed. The cylindrical compression body and the likewise cylindrical first steel disc have the same diameter. This means that the bearing surface, with which the first steel disc rests on the end face of the compression body, is the same size as the end face of the compression body.

Erfolgt bei diesem Felsanker das Einleiten der Zugkräfte auf die erste Stahlscheibe durch den Ankerstab nicht in Richtung der Symmetrieachse des Stauchkörpers, so wird der Stauchkörper nicht zentrisch belastet, d.h. die auf den Stauchkörper wirkende Druckbelastung ist über dessen Stirnfläche ungleichmässig. Das hat ein zunehmendes Abdrehen oder seitliches Kippen des Stauchkörpers zur Folge, was zu einem vorzeitigen Versagen führt und ein Ersetzen des Felsankers erforderlich macht. Dasselbe trifft zu, wenn im Material des Stauchkörpers herstellungsbedingte Schwachstellen oder andere Inhomogenitäten vorhanden sind.If, in the case of this rock bolt, the introduction of the tensile forces onto the first steel disk by the anchor rod does not take place in the direction of the symmetry axis of the compression body, then the compression body is not centrically loaded, i. the compressive load acting on the compression body is uneven over its end face. This results in an increasing twisting or lateral tilting of the compression body, which leads to premature failure and requires replacement of the rock bolt. The same applies if manufacturing-related weak points or other inhomogeneities are present in the material of the compression body.

In der US-A-3,224,202 ist eine Verankerungseinrichtung offenbart, bei der auf der Unterseite einer Platte eine Füllschicht angeordnet ist, die zwischen der Platte und dem Untergrund, z.B. einem Dach, liegt. Diese Füllschicht hat die Aufgabe, bei einem unregelmässigen Profil des Untergrunds dafür zu sorgen, dass zwischen der Platte und dem Untergrund ein enger Kontakt besteht. Die Füllschicht besteht aus einer plastisch deformierbaren Masse, die ein inkompressibles, nicht deformierbares körniges Material (z. B. Sand) und ein deformierbares Bindemittel aus Kunststoff (z. B. Bitumen) aufweist. Bei einer Belastung dieser Füllschicht wird diese plastisch verformt. Das bedeutet, dass bei einer Belastung das Volumen dieser Füllschicht im wesentlichen unverändert bleibt, während deren Form eine Änderung erfährt. Das körnige Material (Sand) ist zwar nicht zusammendrückbar, doch verformt sich das plastische Bindemittel. Bei dieser Verankerungseinrichtung spielt die Grösse der Fläche, mit der die Platte auf der Füllschicht aufliegt, im Vergleich zur Grösse dieser Füllschicht keine entscheidende Rolle.In the US-A-3,224,202 An anchoring device is disclosed in which on the underside of a plate, a filling layer is disposed, which lies between the plate and the substrate, such as a roof. This filling layer has the task of ensuring, with an irregular profile of the substrate, that there is a close contact between the plate and the substrate. The filling layer consists of a plastically deformable mass which comprises an incompressible, non-deformable granular material (eg sand) and a deformable plastic binder (eg bitumen). When loaded, this filling layer is plastically deformed. This means that under a load, the volume of this filling layer remains substantially unchanged, while the shape undergoes a change. The granular material (sand) is not compressible, but deforms the plastic binder. In this anchoring device, the size of the surface with which the plate rests on the filling layer, in comparison to the size of this filling layer does not play a decisive role.

Der vorliegenden Erfindung liegt nun die Aufgabe zugrunde, eine Verankerungseinrichtung der eingangs genannten Art zu schaffen, bei der es auch bei einer nicht symmetrischen Druckbelastung des Stauchkörpers bzw. bei herstellungsbedingten Inhomogenitäten nicht zu einer Verkürzung der Einsatzdauer kommt.The present invention is based on the object to provide an anchoring device of the type mentioned, in which there is no shortening of the service life even with a non-symmetrical pressure load of the compression body or in production-related inhomogeneities.

Diese Aufgabe wird erfindungsgemäss mit einer Verankerungsvorrichtung mit den Merkmalen des Anspruches 1 gelöst.This object is achieved according to the invention with an anchoring device having the features of claim 1.

Da die Kraftübertragungsplatte nur auf einem Teil der Stirnfläche des Stauchkörpers aufliegt, wird bei einer Druckbelastung, die einen bestimmten Wert übersteigt, nur ein innen liegender Bereich des Stauchkörpers zusammen gedrückt, während der aussen liegende Bereich des Stauchkörpers nicht oder nur unwesentlich verformt wird. Deshalb kippt oder verdreht sich der Stauchkörper auch bei einer nicht symmetrischen Belastung und bei Inhomogenitäten, z.B. Schwachstellen, im Material nicht.Since the force transmission plate rests only on a part of the end face of the compression body, at a pressure load exceeding a certain value, only an inner region of the compression body is pressed together, while the outer region of the compression body is not or only slightly deformed. Therefore, the upsetting body tilts or twists even with non-symmetrical loading and inhomogeneities, e.g. Weak points, not in the material.

In der Fig. 1 ist im Längsschnitt und rein schematisch eine erste Ausführungsform einer Verankerungseinrichtung 1 gezeigt, die beim vorliegenden Ausführungsbeispiel zum Stabilisieren eines im Untertagebau ausgebrochenen Hohlraumes, z. B. eines Tunnels, dient. Die Verankerungseinrichtung 1 weist ein Zugglied 2 auf, das mit dem in der Fig. 1 nicht gezeigten Ende 2a auf an sich bekannte Weise im Baugrund 3, d.h. im vorliegenden Fall im Gebirge, verankert ist. An seinem andern, freien Ende 2b wirkt das Zugglied 2 über einen Ankerkopf 4, der im vorliegenden Ausführungsbeispiel als Mutter ausgebildet ist, auf eine Kraftübertragungsplatte 5 (Ankerplatte) ein, die auf einer Stirnfläche 6a eines zylindrischen Stauchkörpers 6 aufliegt. Dieser Stauchkörper 6 stützt sich seinerseits an der Wand 7 des zu sichernden Tunnels ab. Das Zugglied 2 erstreckt sich durch einen Durchlass 8 im Stauchkörper 6 hindurch und durchsetzt den Stauchkörper 6. Dieser Durchlass 8 verläuft koaxial zur Symmetrieachse A des Stauchkörpers 6. Das Zugglied 2 kann auf an sich bekannte Weise aus einem Einzelstab oder einem Litzenbündel bestehen.In the Fig. 1 is a longitudinal section and purely schematically shows a first embodiment of an anchoring device 1, which in the present embodiment for stabilizing a broken hole in the underground cavity, z. B. a tunnel serves. The anchoring device 1 has a tension member 2, with the in the Fig. 1 not shown end 2a in a known manner in the ground 3, that is anchored in the present case in the mountains. At its other, free end 2b, the tension member 2 acts via an anchor head 4, which is formed in the present embodiment as a nut on a force transmission plate 5 (anchor plate), which rests on an end face 6a of a cylindrical compression body 6. This compression body 6 is in turn supported on the wall 7 of the tunnel to be secured. The tension member 2 extends through a passage 8 in the compression body 6 and passes through the compression body 6. This passage 8 extends coaxially to the axis of symmetry A of the compression body 6. The tension member 2 may consist of a single rod or a strand bundle in a known per se.

Der Stauchkörper 6 besteht aus einem kompressiblen Material und entspricht im Aufbau und der Wirkungsweise dem in der vorstehend erwähnten EP-A- 1 564 369 beschriebenen Stauchkörper. Dementsprechend besteht der Stauchkörper 6 aus bei einer bestimmten Druckbelastung sich verformenden, d.h. zusammendrückbaren, Partikeln sowie Verstärkungselementen, die in ein Bindemittel, z.B. Zement oder Kunststoff (Kunstharz), eingebettet sind. Vorzugsweise sind diese Partikel Blähglaspartikel, z.B. Blähglasgranulat. Unter Umständen können auch Partikel aus einem andern geeigneten Material, z.B. aus Kunststoff oder Stahlschaum, verwendet werden. Die Verstärkungselemente bestehen vorzugsweise aus Stahl, können aber auch aus Kunststoff oder Glas sein. Dabei werden Verstärkungselemente in der Form von Fasern, Gittern, Netzen, Stäben oder Platten mit oder ohne Öffnungen verwendet. Eine mögliche Zusammensetzung des Gemisches, aus dem der Stauchkörper 6 besteht, ist in der bereits erwähnten EP-A- 1 564 369 angegeben.The compression body 6 is made of a compressible material and corresponds in construction and the operation in the above-mentioned EP-A-1 564 369 described compression body. Accordingly, the compression body 6 consists of deforming at a certain pressure load, ie compressible, particles and reinforcing elements, which are embedded in a binder, such as cement or plastic (synthetic resin). Preferably, these particles are expanded glass particles, eg expanded glass granules. Under certain circumstances, particles of another suitable material, such as plastic or steel foam, can be used. The reinforcing elements are preferably made of steel, but may also be made of plastic or glass. In this case, reinforcing elements in the form of fibers, meshes, nets, rods or plates with or without openings are used. A possible composition of the mixture of which the compression body 6 consists is already mentioned EP-A-1 564 369 specified.

Der Stauchkörper 6 kann auch mit mindestens einem platten- oder gitterförmigen Bewehrungselement versehen sein, das quer und vorzugsweise rechtwinklig zur Belastungsrichtung, d.h. zur Symmetrieachse A, verläuft. Dieses Bewehrungselement, das eine hohe mechanische Festigkeit aufweist, kann in das Grundmaterial (Bindemittel) des Stauchkörpers 6 eingebettet sein.The upsetting body 6 may also be provided with at least one plate or grid-shaped reinforcing element which is transversely and preferably at right angles to the direction of loading, i. to the axis of symmetry A, runs. This reinforcing element, which has a high mechanical strength, may be embedded in the base material (binder) of the compression body 6.

Im Bereich seines Umfanges 6b ist der Stauchkörper 6 mit einer Bewehrung 9 versehen, die verhindern soll, dass bei einer Druckbelastung des Stauchkörpers 6 Material in einer Richtung quer zur Belastungsrichtung verdrängt werden kann. Der Stauchkörper 6 soll somit bei einer Druckbelastung keine oder höchstens eine sehr geringe Verformung in einer Richtung quer zur Symmetrieachse A erfahren können. Beim gezeigten Ausführungsbeispiel besteht die Bewehrung 9 aus Stahldrähten oder Stahlbändern 10, die ringförmig oder spiralförmig verlaufend in Umfangsrichtung des Stauchkörpers 6 in diesen eingelegt sind. Es ist auch möglich, diese Stahldrähte oder Stahlbänder ring- oder spiralförmig auf der Aussenseite des Stauchkörpers 6 um diesen herum zu spannen. Die Bewehrung kann auch durch einen zylindrischen Mantel aus einem zugfesten Material, der den Stauchkörper 6 auf dessen Aussenseite umgibt, gebildet werden.In the region of its circumference 6b of the compression body 6 is provided with a reinforcement 9, which is to prevent that at a pressure load of the compression body 6 material in one Direction can be displaced transversely to the loading direction. The compression body 6 should therefore be able to experience no or at most a very small deformation in a direction transverse to the axis of symmetry A at a pressure load. In the illustrated embodiment, the reinforcement 9 is made of steel wires or steel strips 10, which are annular or spirally extending in the circumferential direction of the compression body 6 inserted into this. It is also possible, these steel wires or steel bands ring or spirally on the outside of the compression body 6 to stretch around it. The reinforcement can also be formed by a cylindrical shell of a tensile material surrounding the compression body 6 on the outside thereof.

Wie die Fig. 1 zeigt ist der Durchmesser D1 der Kraftübertragungsplatte 5 kleiner als der Durchmesser D2 des Stauchkörpers 6. Das bedeutet, dass die Auflagefläche 11, mit der die Kraftübertragungsplatte 5 an der Stirnfläche 6a des Stauchkörpers anliegt, kleiner ist als diese Stirnfläche 6a.As the Fig. 1 shows that the diameter D1 of the power transmission plate 5 is smaller than the diameter D2 of the compression body 6. That means that the support surface 11, with which the force transmission plate 5 abuts against the end face 6a of the compression body, is smaller than this end face 6a.

Anhand der Fig. 1 und 2 wird nachfolgend die Wirkungsweise der Verankerungseinrichtung 1 erläutert.Based on Fig. 1 and 2 the mode of operation of the anchoring device 1 will be explained below.

In Fig. 1 ist der Zustand dargestellt, bei dem der Stauchkörper 6 der auf ihn einwirkenden Druckbelastung noch standhalten kann und demzufolge noch kein Zusammendrücken des Stauchkörpers 6 stattfindet. Bei Bewegungen im Baugrund 3 erhöht sich die Zugkraft im Zugglied 2, die auf die Kraftübertragungsplatte 5 übertragen wird. Überschreitet nun die von der Kraftübertragungsplatte 5 auf den Stauchkörper 6 übertragene Druckbelastung einen bestimmten Wert, so wird der Stauchkörper 6 verformt und im Bereich unterhalb der Kraftübertragungsplatte 5 zusammengedrückt. Auf diese Weise wird das Zugorgan 2 nicht überbeansprucht. Dieser Verformungsvorgang des Stauchkörpers 6 ist in der früher erwähnten EP-A- 1 564 369 im Zusammenhang mit den Fig. 3 - 5 ausführlicher beschrieben. Wie in der Fig. 2 gezeigt dringt dabei die Kraftübertragungsplatte 5 in den Stauchkörper 6 ein. Unterhalb der Kraftübertragungsplatte 5 bildet sich ein Stauchbereich 12, in dem das Material des Stauchkörpers 6 zusammengedrückt wird. Im diesen Stauchbereich 12 umgebenden Bereich 13 des Stauchkörpers 6, insbesondere im Bereich seines Umfanges 6b, erfolgt kein Zusammendrücken des Materials, d.h. das Material in diesem Bereich 13 behält seine ursprüngliche Festigkeit bei. Das hat zur Folge, dass der Stauchkörper 6 auch bei einer nicht symmetrischen Belastung oder bei Schwachstellen im Material stabil bleibt und nicht dazu neigt, nach der Seite umzukippen.In Fig. 1 is shown the state in which the compression body 6 of the pressure load acting on it can still withstand and therefore no compression of the compression body 6 takes place. When moving in the ground 3, the tensile force increases in the tension member 2, which is transmitted to the power transmission plate 5. If the pressure load transmitted by the force transmission plate 5 to the compression body 6 exceeds a specific value, then the compression body 6 is deformed and in the region below the pressure Power transmission plate 5 compressed. In this way, the tension member 2 is not overstressed. This deformation process of the compression body 6 is in the earlier mentioned EP-A-1 564 369 in connection with the Fig. 3-5 described in more detail. Like in the Fig. 2 shown penetrates the power transmission plate 5 in the compression body 6 a. Below the force transmission plate 5 forms a compression region 12, in which the material of the compression body 6 is compressed. In this area 12 surrounding area 13 of the compression body 6, in particular in the region of its circumference 6b, there is no compression of the material, ie, the material in this area 13 retains its original strength. This has the consequence that the compression body 6 remains stable even with a non-symmetrical load or weak points in the material and does not tend to tip over to the side.

Wie bereits erwähnt verhindert die Bewehrung 9, dass bei einer Druckbelastung des Stauchkörpers 6, wie sie in der Fig. 2 dargestellt ist, Material nach der Seite ausweichen kann. Die Bewehrung 9 hält den Stauchkörper 6 zusammen.As already mentioned prevents the reinforcement 9, that at a pressure load of the compression body 6, as in the Fig. 2 is shown, can dodge material to the side. The reinforcement 9 holds the compression body 6 together.

Beim in der Fig. 3 gezeigten weiteren Ausführungsbeispiel einer Verankerungseinrichtung 1' liegt der anhand der Fig. 1 und 2 beschriebene Stauchkörper 6 nicht direkt an der Tunnelwand 7 an, sondern liegt auf einem zweiten Stauchkörper 14 auf, der sich an der Tunnelwand 7 abstützt. Dieser zweite Stauchkörper 14 besteht aus dem gleichen Material wie der erste Stauchkörper 6 und ist zu letzterem koaxial angeordnet. Der zweite Stauchkörper 14 weist ebenfalls einen Durchlass 15 auf, durch den das Zugglied 2 hindurch verläuft. Dieser Durchlass 15 hat einen grösseren Durchmesser als der Durchlass 8 im oberen Stauchkörper 6. Das bei einer Druckbelastung im oberen Stauchkörper 6 zusammengedrückte, verdichtete Material (Stauchbereich 12 in Fig. 2) kann in diesen erweiterten Durchlass 15 im unteren Stauchkörper 14 ausweichen.When in the Fig. 3 shown further embodiment of an anchoring device 1 'is based on the Fig. 1 and 2 described upsetting body 6 is not directly on the tunnel wall 7, but rests on a second compression body 14 which is supported on the tunnel wall 7. This second compression body 14 is made of the same material as the first compression body 6 and is arranged coaxially to the latter. The second compression body 14 also has a passage 15 through which the tension member 2 passes. This passage 15 has a larger diameter than the passage 8 in the upper compression body 6. The at a pressure load in the upper Compression body 6 compressed, compressed material (compression area 12 in Fig. 2 ) can escape into this enlarged passage 15 in the lower compression body 14.

Gleich wie der erste Stauchkörper 6 ist auch der zweite Stauchkörper 14 im Bereich seines Umfanges 14a mit einer Bewehrung 16 versehen, die ein seitliches Ausweichen des Materials verhindern soll. Diese Bewehrung wird ebenfalls durch Stahldrähte oder Stahlbänder 17 gebildet, die ringförmig oder spiralförmig verlaufend in Umfangsrichtung des zweiten Stauchkörpers 14 in diesen eingelegt sind. Gleich wie beim ersten Stauchkörper 6 ist es auch möglich, diese Stahldrähte oder Stahlbänder ring- oder spiralförmig auf der Aussenseite des zweiten Stauchkörpers 14 um diesen herum zu spannen. Die Bewehrung kann auch beim zweiten Stauchkörper 14 durch einen zylindrischen Mantel aus einem zugfesten Material, der den zweiten Stauchkörper 14 auf dessen Aussenseite umgibt, gebildet werden.Like the first compression body 6 and the second compression body 14 is provided in the region of its circumference 14a with a reinforcement 16 which is intended to prevent lateral deflection of the material. This reinforcement is also formed by steel wires or steel strips 17, which are inserted annularly or spirally extending in the circumferential direction of the second compression body 14 in this. As with the first compression body 6, it is also possible to tension these steel wires or steel bands in a ring or spiral shape on the outside of the second compression body 14 around it. The reinforcement can also be formed in the second compression body 14 by a cylindrical shell of a tensile material surrounding the second compression body 14 on the outside thereof.

Die Wirkungsweise bei der Ausführungsform gemäss Fig. 3 bei einer einen bestimmten Wert übersteigenden Druckbelastung ist dieselbe wie anhand der Fig. 1 und 2 beschrieben.The mode of action in the embodiment according to Fig. 3 at a pressure exceeding a certain value is the same as based on the Fig. 1 and 2 described.

In den Fig. 4 und 5 sind mögliche Anwendungsgebiete der vorstehend anhand der Fig. 1 - 3 beschriebenen Verankerungseinrichtungen 1, 1' dargestellt.In the Fig. 4 and 5 are possible applications of the above with reference to the Fig. 1-3 described anchoring devices 1, 1 'shown.

Die Fig. 4 zeigt rein schematisch einen Querschnitt durch einen im Untertagbau ausgebrochenen Hohlraum 18, z.B. einen Tunnel oder eine Kaverne, wobei die Bodenplatte aus Beton und eine allfällige Betonauskleidung nicht dargestellt sind. So kann die mit 1a bezeichnete Verankerungseinrichtung zum Stabilisieren von Bewegungen in der Wand 18a des ausgebrochenen Hohlraumes 18 bei druckhaftem Gebirge Verwendung finden. Die erfindungsgemässe Verankerungseinrichtung kann auch zur Stabilisierung von Bewegungen des Bodens oder der Sohle 19 des ausgebrochenen Hohlraumes 18 bei quellfähigem oder druckhaftem Gebirge verwendet werden (Auftriebssicherung), wie das durch die in Fig.4 mit 1b bezeichneten Verankerungseinrichtungen dargestellt ist.The Fig. 4 shows purely schematically a cross section through an excavated in the underground cavity 18, for example, a tunnel or a cavern, wherein the bottom plate made of concrete and a possible concrete lining are not shown. Thus, the anchoring means indicated at 1a can stabilize movements in the wall 18a of the excavated cavity 18 at pressure mountains are used. The anchoring device according to the invention can also be used for stabilizing movements of the bottom or the sole 19 of the excavated cavity 18 in the case of swellable or pressurized mountains (buoyancy protection), as is provided by the in FIGS Figure 4 1b is shown anchoring devices.

Ein weiteres Anwendungsgebiet für eine erfindungsgemässe Verankerungseinrichtung ist die Sicherung bei Hangbewegungen (Fig. 5). In dieser Fig. 5 dienen mehrere Verankerungseinrichtungen 1c, deren Zugstäbe 2 mit den Enden 2a im Hangmaterial 20 (z.B. Fels oder Lockergestein) verankert sind, dazu, einen rutschgefährdeten Hangbereich 21 zu stabilisieren.Another field of application for an anchoring device according to the invention is securing in the case of slope movements ( Fig. 5 ). In this Fig. 5 serve several anchoring devices 1c, the tension rods 2 are anchored to the ends 2a in the slope material 20 (eg rock or unconsolidated rock), to stabilize a non-slip slope area 21.

Die Kraftübertragungsplatte 5 kann auch eine andere als eine zylindrische Form haben und z.B. quadratisch oder mehreckig ausgebildet sein. Wichtig ist dabei, dass die Auflagefläche der Kraftübertragungsplatte 5, d.h. die Belastungsfläche, mit der letztere auf der Stirnfläche 6a des Stauchkörpers 6 aufliegt, kleiner ist als diese Stirnfläche 6a des Stauchkörpers 6. Vorzugsweise ist die Kraftübertragungsplatte 5 symmetrisch bezüglich der Belastungsachse, d.h. der Symmetrieachse A des Stauchkörpers 6, ausgebildet.The power transmission plate 5 may also have a shape other than a cylindrical shape and e.g. be formed square or polygonal. It is important that the bearing surface of the power transmission plate 5, i. the load surface with which the latter rests on the end face 6a of the compression body 6 is smaller than this end face 6a of the compression body 6. Preferably, the force transmission plate 5 is symmetrical with respect to the loading axis, i. the symmetry axis A of the compression body 6, formed.

Es versteht sich, dass die anhand der Fig. 1 - 3 beschriebene Verankerungseinrichtung 1, 1' sich noch für den Einsatz in andern als den erwähnten Gebieten eignet.It is understood that the basis of the Fig. 1-3 described anchoring device 1, 1 'is still suitable for use in other than the mentioned areas.
