Description

Die Erfindung bezieht sich auf einen Anker der im Oberbegriff des Anspruchs 1 genannten Art.The invention relates to an anchor in the preamble of claim 1 Art.

Derartige Anker dienen zur Fixierung von zwei Bauteilen aneinander, beispielsweise bei einem Schalenmauerwerk zur Fixierung der beiden Mauerwerkschalen, zwischen denen ein Zwischenraum gebildet ist, in welchem in der Regel eine Wärmedämmschicht angeordnet wird.Such anchors are used to fix two components to each other, for example in a shell masonry Fixing the two masonry shells, between which one Intermediate space is formed, in which usually one Thermal insulation layer is arranged.

Infolge von Temperaturänderungen, beispielsweise Erwärmung im Sommer und Abkühlung im Winter, sowie Verformungen, beispielsweise Schwund durch Austrocknen und Quellen durch Feuchtigkeit, unterliegt die äussere Mauerwerkschale, nachfolgend auch Aussenschale genannt, Längenänderungen. Deshalb sollen derartige Anker zur Vermeidung von Biegezug- und Zwängsspannungen, welche zu Rissbildungen führen, nachgiebig sein, um Vertikal- und Horizontalbewegungen parallel zur Wandebene zuzulassen. Hingegen sollen derartige Anker zur Aufnahme von Winddruck und Windsog keine Bewegungen senkrecht zur Wandebene zulassen.As a result of temperature changes, for example heating in summer and cooling in winter, as well as deformations, for example shrinkage due to drying out and swelling Moisture, is subject to the outer masonry shell, hereinafter also called outer shell, changes in length. Therefore, such anchors should be used to avoid and constraining stresses that lead to crack formation, be compliant to vertical and horizontal movements allow parallel to the wall level. On the contrary such anchors for taking up wind pressure and wind suction do not allow movements perpendicular to the wall plane.

Zu diesem Zweck weist ein aus der DE-A1-41 29 032 bekannter Anker relativ zueinander bewegliche Verankerungsglieder auf, die gegenüberliegend in den beiden Mauerwerkschalen eingedübelt oder eingemauert werden. Die Beweglichkeit wird durch ein speziell ausgebildetes Verbindungsglied erzielt, welches die Verankerungsglieder miteinander verbindet. Dabei sind die Verankerungsglieder zwar drehbar, jedoch unlösbar am Ankerkopf befestigt. For this purpose, a known from DE-A1-41 29 032 Anchoring members movable relative to each other on, the opposite in the two masonry shells be pegged or walled in. The agility will achieved by a specially designed connecting link, which connects the anchoring members together. The anchoring members are rotatable, however permanently attached to the anchor head.

Solche durch die Unlösbarkeit einstückig ausgebildeten Anker lassen sich wegen des Ankerkopfes nur erschwert exakt rechtwinklig zum Mauerwerk einbauen. Auch ist es praktisch unmöglich, solche Anker nachträglich im rechten Winkel zu justieren.Such one-piece formed by the insolubility Anchors are difficult to exact because of the anchor head Install at right angles to the masonry. It is also practical impossible to retrofit such anchors at right angles adjust.

Ferner weisen aus den CH-Patentschriften CH-A-565 908 und CH-A-643 024 bekannte Anker sowie auch andere handelsübliche Draht- und Luftschichtanker die gleiche Problematik auf.Furthermore, from CH patents CH-A-565 908 and CH-A-643 024 known anchors as well as other commercially available Wire and air layer anchors present the same problem.

Ein rechtwinkliger Einbau senkrecht zur Wandebene ist jedoch bei allen bekannten Arten von Ankern für die Funktionstüchtigkeit eines Zweischalenmauerwerks unabdingbare Voraussetzung. Beispielsweise würden wahllos schräg nach oben oder unten geneigte oder hingebogene Anker, welche sich gegenseitig sperren, zu Zwängsspannungen führen. Solche Anker sind entweder funktionsuntüchtig oder praktisch wirkungslos. Es entstehen dadurch relativ starre Verbindungen, welche ein zwängsfreies Bewegen der Aussenschale verhindern. Der in den letzten Jahren infolge dickerer Wärmedämmschichten grösser gewählte Abstand zwischen den Mauerwerkschalen erhöht das genannte Problem erheblich. Die Tauglichkeit der heute bekannten Anker bezüglich des vorgesehenen planmässigen Einbaues ist dadurch fraglich.A right-angled installation is perpendicular to the wall plane however, for all known types of anchors for functionality of a two-shell masonry indispensable Requirement. For example, would randomly slant after Anchors inclined or bent up or down, which lock each other, lead to constraint tensions. Such anchors are either inoperative or practical ineffective. This creates relatively rigid Connections that require an unrestricted movement of the outer shell prevent. The one in recent years due to thicker Thermal insulation layers larger selected distance between the masonry shells significantly increases the problem mentioned. The suitability of the anchors known today regarding the scheduled installation is questionable.

Ferner behindern unförmige Verbindungsanker das fachgerechte und möglichst kältebrückenfreie Einbringen des Wärmedämmstoffes.Furthermore, bulky connecting anchors hinder the professional and, if possible, the thermal insulation material is brought in without cold bridges.

Ein Anker gemäss dem Oberbegriff des Anspruchs 1 ist aus der US-A-4 746 069 bekannt. Bei diesem Anker ist ein erstes Verankerungsglied mit einem einen Führungsschlitz aufweisenden Verbindungsmittel lösbar verbunden. Ein zweites Verankerungsglied ist an seinem rechtwinklig zur Längserstreckung abgewinkelten Ende u-förmig ausgebildet und mit dem freien Schenkel des u-förmigen Teils in den Führungsschlitz des Verbindungsmittels einschiebbar. In Richtung des freien Schenkels sind die beiden Verankerungsglieder relativ zueinander verschiebbar. Nachteilig ist an diesem bekannten Anker, dass seine beiden Verankerungsglieder mit ihren Achsen zueinander versetzt angeordnet sind, also nicht miteinander fluchten. Ferner ist es nachteilig, dass zum Zusammenfügen eine Querbewegung in bezug auf ihre Achserstreckung erforderlich ist. Der Achsversatz und oder ein Schrägeinbau ergibt bei durch Winddruck erzeugten Kräften eine Knickbeanspruchung in der Kraftübertragung auf die Stützmauer. Durch die Knickbeanspruchung können die beanspruchten Teile deformiert werden, so dass der Anker seinen Zweck nicht mehr erfüllen kann.An anchor according to the preamble of claim 1 is out U.S.-A-4,746,069. There is a first one with this anchor Anchoring member with a guide slot Lanyards releasably connected. A second Anchoring member is at right angles to its longitudinal extent angled end u-shaped and with the free leg of the U-shaped part in the guide slot the connecting means can be inserted. In the direction of the free leg are the two anchoring members slidable relative to each other. The disadvantage of this known anchor that its two anchoring links with their axes are staggered, so not cursing with each other. It is also disadvantageous that to put together a transverse movement with respect to their Axis extension is required. The axis offset and or inclined installation results in wind pressure Force a kink load in the power transmission the retaining wall. Due to the buckling stress, the stressed parts are deformed so that the anchor can no longer serve its purpose.

Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Anker zu schaffen, der keine auf Knick beanspruchten Teile aufweist und der sich exakt rechtwinklig zum Mauerwerk befestigen und justieren lässt. Ferner soll er einen einwandfreien ankerumschliessenden Einbau des Wärmedämmstoffes ermöglichen.The invention is therefore based on the object To create anchors that have no stressed parts and which is exactly perpendicular to the masonry can be attached and adjusted. Furthermore, he should be one perfect anchor-enclosing installation of the thermal insulation material enable.

Die gestellte Aufgabe wird erfindungsgemäss durch die im Anspruch 1 angegebenen Merkmale gelöst.According to the invention, the object is achieved by the Features specified claim 1 solved.

Der erfindungsgemässen Lösung liegt ein zweiteilig ausgebildeter Anker zugrunde, bei welchem vorerst das von seinem Verbindungsmittel gelöste stangenförmige Verankerungsglied in der inneren Mauerwerkschale rechtwinklig verankert und justiert wird und anschliessend nach einem problemlosen Überstülpen des Wärmedämmstoffes die Befestigung des Ankerkopfes - bestehend aus einem Profilkörper und dem zweiten Verankerungsglied - erfolgt.The solution according to the invention is a two-part solution Based on anchor, for the time being that of his Connecting means loosened rod-shaped anchoring member anchored at right angles in the inner masonry shell and is adjusted and then after a problem-free Slip the thermal insulation over the fastening of the Anchor head - consisting of a profile body and the second anchoring link - done.

Durch die Ausbildung des zweiten Verankerungsgliedes als Ankerplatte wird der Kontakt zwischen dieser und dem Profilkörper auf ein Minimum beschränkt, so dass eine möglichst grosse Wärmedämmung zwischen den Verankerungsgliedern erzielt wird. Ferner lassen sich die Verankerungsglieder bei der erfindungsgemässe Ausführung in Achsrichtung zusammenfügen.By designing the second anchor member as Anchor plate is the contact between this and the Profile body limited to a minimum, so that as possible large thermal insulation between the anchoring members is achieved. Furthermore, the anchoring members can be in the embodiment according to the invention in the axial direction put together.

Die abhängigen Ansprüche beschreiben bevorzugte Ausführungsformen der Erfindung.The dependent claims describe preferred embodiments the invention.

Anhand der Zeichnung wird ein Ausführungsbeispiel der Erfindung näher erläutert. Es zeigen:

Aus der Stirnansicht nach Fig. 2 ist ersichtlich, dass ein Profilkörper 10 als Führungselement einen Führungsschlitz 12 bzw. ein Langloch aufweist, in welchem eine Ankerplatte 14 als Verankerungsglied in Längsrichtung 16A zum Führungsschlitz 12 und zu einem Teil auch in Querrichtung 16B verschiebbar geführt ist.From the front view according to FIG. 2 it can be seen that a profile body 10 as a guide element has a guide slot 12 or an elongated hole, in which an anchor plate 14 as an anchoring member is slidably guided in the longitudinal direction 16A to the guide slot 12 and in part also in the transverse direction 16B .

Aus der Seitenansicht nach Fig. 1 geht hervor, dass am Profilkörper 10 eine Mutter 18 angeschweisst ist, in welche eine Ankerstange 20 bzw. ein Ankerbolzen als Verankerungsglied mittels eines Gewindes 22 eingeschraubt ist. Die verkürzt dargestellte Ankerstange 20 weist an ihrem vom Profilkörper 10 entfernten Ende Befestigungsmittel in Form eines Gewindes 24 auf. Damit kann die Ankerstange 20 im Mauerwerk eingedübelt oder eingemauert werden. Das Gewinde 24 kann beispielsweise auch ein Holzgewinde sein, um die Ankerstange 20 damit in einen für ein solches Gewinde bestimmten, im Mauerwerk eingelassenen Dübel einzuschrauben. Selbstverständlich ist es auch möglich, andersartige Befestigungsmittel vorzusehen, beispielsweise in Form einer Steinschraube. Auch die Befestigung der Ankerstange 20 am Profilkörper 10 kann mit anderen Mitteln als mit einer angeschweissten Mutter erfolgen, jedoch vorzugsweise unter Einhaltung einer relativen Verdrehbarkeit. Die Ankerplatte 14 und der Profilkörper 10 bilden zusammen den Ankerkopf.1 shows that a nut 18 is welded onto the profile body 10 , into which an anchor rod 20 or an anchor bolt is screwed as an anchoring member by means of a thread 22 . The shortened anchor rod 20 has fastening means in the form of a thread 24 at its end remote from the profile body 10 . This allows the anchor rod 20 to be dowelled or walled in. The thread 24 can also be a wood thread, for example, in order to screw the anchor rod 20 into a dowel intended for such a thread and embedded in the masonry. Of course, it is also possible to provide different types of fastening means, for example in the form of a stone screw. The anchor rod 20 can also be fastened to the profile body 10 using other means than with a welded-on nut, but preferably while maintaining a relative rotatability. The anchor plate 14 and the profile body 10 together form the anchor head.

Vorzugsweise ist die Länge der Ankerstange 20 derart zu bemessen, dass diese die Wärmedämmschicht durchdringt und der Ankerkopf 10 an die Wärmedämmschicht angrenzt. Damit lässt sich eine Aussparung in der Wärmedämmschicht für den Ankerkopf 10 vermeiden. The length of the anchor rod 20 is preferably dimensioned such that it penetrates the thermal insulation layer and the anchor head 10 adjoins the thermal insulation layer. A cutout in the thermal insulation layer for the anchor head 10 can thus be avoided.

Um die Verschiebbarkeit der Ankerplatte 14 in Pfeilrichtungen 16A im Profilkörper 10 zu verdeutlichen, ist der Profilkörper im Längsschnitt dargestellt, in welchem der Führungsschlitz 12 ersichtlich ist.In order to clarify the displaceability of the anchor plate 14 in the arrow directions 16A in the profile body 10 , the profile body is shown in longitudinal section, in which the guide slot 12 can be seen.

Aus der Draufsicht nach Fig. 3 geht hervor, dass der Profilkörper 10 im Querschnitt rechteckig ist. In den Innenraum 26 des Profilkörpers 10 greift die Ankerplatte 14 mit einem als Eingriffselement zum Führungsschlitz 12 dienenden Führungsansatz 28 ein. Dieser ist einstückig an der Ankerplatte 14 angeformt und breiter als der Führungsschlitz 12. Zur Ausbildung des Führungsansatzes 28 weist die Ankerplatte 14 auf beiden Seiten Einschnitte 30 auf, so dass sie schlüsselartig durch Drehen in den Führungsschlitz 12 eingesetzt werden kann.3 shows that the profile body 10 is rectangular in cross section. The anchor plate 14 engages in the interior 26 of the profile body 10 with a guide projection 28 serving as an engagement element for the guide slot 12 . This is integrally formed on the anchor plate 14 and wider than the guide slot 12 . To form the guide projection 28 , the anchor plate 14 has incisions 30 on both sides, so that it can be inserted into the guide slot 12 in a key-like manner by turning.

Ein zwischen den Einschnitten 30 gebildeter Steg 31 (Fig. 2) ist schmäler als der Führungsschlitz in seiner Breite, so dass die Ankerplatte 14 in eingesetzter Stellung nicht nur in Längsrichtung 16A zum Führungsschlitz 12, sondern auch in Querrichtung 16B relativ zu diesem, also rechtwinklig zur Achse der Verankerungsglieder 14, 20 verschiebbar ist. Durch die Ausbildung der Schlitze 30 ist die Ankerplatte 14 jedoch im wesentlichen in Achsrichtung zu den Verankerungsgliedern 14, 20 unverschiebbar.A web 31 (FIG. 2) formed between the incisions 30 is narrower in width than the guide slot, so that the anchor plate 14 in the inserted position not only in the longitudinal direction 16A to the guide slot 12 , but also in the transverse direction 16B relative thereto , that is to say at right angles is displaceable to the axis of the anchoring members 14 , 20 . Due to the formation of the slots 30 , the anchor plate 14 is essentially immovable in the axial direction to the anchoring members 14 , 20 .

Ein in den Figuren 4 und 5 dargestellter Klemmkörper 32 wird von einer der beiden offenen Seiten in den Profilkörper 10 eingesetzt, bevor die Ankerplatte 14 mit ihrem Führungsansatz 28 durch den Führungsschlitz 12 eingeführt wird. Beim Einführen der Ankerplatte 14 wird durch ihren Führungsansatz 28 eine Vertiefung 34 in den Klemmkörper 32 geprägt. Beim nachfolgenden schlüsselartigen Drehen der Ankerplatte 14 im Profilkörper 10 wird der Klemmkörper 32 mitgedreht. Er ist derart bemessen, dass er eine leichte Klemmwirkung im Profilkörper 10 ausübt, so dass die Ankerplatte 14 vor dem Einbau des Ankers im Profilkörper 10 gegen Herausfallen gesichert ist.A clamping body 32 shown in FIGS. 4 and 5 is inserted into the profile body 10 from one of the two open sides before the anchor plate 14 with its guide projection 28 is inserted through the guide slot 12 . When the anchor plate 14 is inserted, an indentation 34 is formed in the clamping body 32 by its guide projection 28 . During the subsequent key-like rotation of the anchor plate 14 in the profile body 10 , the clamping body 32 is also rotated. It is dimensioned such that it exerts a slight clamping effect in the profile body 10 , so that the anchor plate 14 is secured against falling out before the anchor is installed in the profile body 10 .

Der zur besseren Übersicht in den Figuren 1 und 3 nicht dargestellte Klemmkörper 32 besteht vorzugsweise aus einem geschäumten Kunststoff, der auch unter dem Markennamen Styropor bekannt ist. Alternativ zur vorstehend beschriebenen Ausführung ist es auch möglich, den Profilkörper 10 bei eingesetzter Ankerplatte 14 mit einem derartigen Kunststoff auszuschäumen.The clamping body 32, which is not shown in FIGS. 1 and 3 for a better overview, preferably consists of a foamed plastic, which is also known under the brand name styrofoam. As an alternative to the embodiment described above, it is also possible to foam the profile body 10 with such a plastic when the anchor plate 14 is inserted.

Bei einer Verschiebung der Ankerplatte 14 relativ zur Ankerstange 20 in Pfeilrichtungen 16A, also in Längsrichtung zum Führungsschlitz 12 wird der Klemmkörper 32 im Profilkörper 10 mitverschoben. Eine solche Verschiebung ist möglich, da der Profilkörper 10 in Längsrichtung zu seinem Profil offen ist. Eine Verschiebung in Pfeilrichtungen 16B, also quer zur Längserstreckung des Führungsschlitzes 12, ist ebenfalls möglich, da die Einschnitte 30 in der Ankerplatte 14 ein Spiel im Führungsschlitz 12 ermöglichen. Dabei erweitert der Führungsansatz 28 die Vertiefung 34 im Klemmkörper 32.When the anchor plate 14 is displaced relative to the anchor rod 20 in the arrow directions 16A , that is to say in the longitudinal direction to the guide slot 12 , the clamping body 32 is also displaced in the profile body 10 . Such a shift is possible because the profile body 10 is open to its profile in the longitudinal direction. A displacement in the arrow directions 16B , that is to say transversely to the longitudinal extent of the guide slot 12 , is also possible since the incisions 30 in the anchor plate 14 allow play in the guide slot 12 . The guide extension 28 extends the recess 34 in the clamping body 32 .

Die beiden Verankerungsglieder 14, 20 sind derart bemessen, dass sie an ihren Berührungsflächen eine möglichst kleine metallische Wärmebrücke zwischen Innen- und Aussenschale bilden.The two anchoring members 14 , 20 are dimensioned such that they form the smallest possible metallic thermal bridge between the inner and outer shell on their contact surfaces.

Als Befestigungsmittel zum Einmauern weist die Ankerplatte 14 gemäss Fig. 3 Löcher 36 auf. The anchor plate 14 according to FIG. 3 has holes 36 as fastening means for walling in.

Eine Mehrzahl von Ankern der vorstehend beschriebenen Art dient zum Verankern der beiden Mauerteile aneinander, wobei eine Verschiebung des einen Mauerteils relativ zum anderen keine Abstandsänderung bewirkt, da diese Anker eine parallele Verschiebung quer zu ihrer Achsrichtung ermöglichen. Damit werden Rissbildungen im Mauerwerk infolge Biegezugspannungen vermieden.A plurality of anchors of the type described above serves to anchor the two wall parts to each other, whereby a displacement of one part of the wall relative to the other no change in distance, because these anchors are parallel Allow displacement transverse to their axis direction. This will cause cracks in the masonry due to bending tensile stresses avoided.

Zwischen den beiden Mauerteilen ist durch den erfindungsgemässen Anker jedoch in bezug auf deren Abstand voneinander eine starre Verankerung gewährleistet. Dies ist beispielsweise bei Windkräften wichtig, indem der äussere Mauerteil am inneren abgestützt und verankert ist. Ein federelastischer Anker, wie beispielsweise aus der CH-Patentschrift 441 679 bekannt, kann eine solche Aufgabe nicht erfüllen.Between the two parts of the wall is by the inventive Anchors, however, in terms of their distance from each other rigid anchoring guaranteed. This is important for wind power, for example, by the outer Wall part is supported and anchored on the inside. A spring-elastic anchor, such as from the CH patent 441 679 known, can be such a task not meet.

Eine Ankeranordnung mit einer starren Ankerkonsole und einem beweglichen Ankerkopf, welcher in unmittelbarer Nähe des verschiebbaren Bauteils montiert ist, gewährleistet auch die geforderte zwängsfreie Bewegung der Aussenschale. Im Gegensatz zu den bekannten Ankern treten in den hier beschriebenen Ankergliedern keine Biegebeanspruchungen auf.An anchor arrangement with a rigid anchor bracket and a movable anchor head, which is in the immediate vicinity of the slidable component is guaranteed also the required free movement of the outer shell. In contrast to the well-known anchors occur in the here described anchor members no bending stresses.

Der erfindungsgemässe Anker verhindert eine Durchfeuchtung des Wärmedämmstoffes, da eventuell eindringendes Regenwasser, welches an der Innenseite der Aussenschale abläuft, am Ankerkopf abtropfen kann.The anchor according to the invention prevents moisture penetration of the thermal insulation material, as rainwater may penetrate, which runs on the inside of the outer shell, can drip on the anchor head.

Anstelle der im Ausführungsbeispiel beschriebenen Verankerungsglieder in Form von Ankerstange 20 und Ankerplatte 14 ist es auch möglich, beiderseits Verankerungsstangen oder Verankerungsplatten anzuordnen.Instead of the anchoring members described in the exemplary embodiment in the form of anchor rod 20 and anchor plate 14 , it is also possible to arrange anchoring rods or anchoring plates on both sides.

Der Führungsschlitz 12 kann anstelle in einem Profilkörper kann auch im Verankerungsglied selbst angeordnet sein.The guide slot 12 can also be arranged in the anchoring member itself instead of in a profile body.

Es ist auch denkbar, den Führungsansatz anstelle an einer Ankerplatte an einer Ankerstange auszubilden oder zu befestigen. Der Profilkörper kann auch einen einerends oder beiderends offenen Führungsschlitz aufweisen, um das Einsetzen eines Führungsansatzes zu ermöglichen, der anders als im Ausführungsbeispiel geformt ist, beispielsweise als Kugel oder Scheibe.It is also conceivable to use the leadership approach instead of one Form or attach anchor plate to an anchor rod. The profile body can also be one end or have open guide slots at both ends to the Enabling a leadership approach that is different than is shaped in the embodiment, for example as Bullet or disc.

Der beschriebene Anker ermöglicht mit der einfach ausgebildeten Stabform des starren Ankerbolzens einen planmässig horizontalen Einbau bzw. einen Einbau rechtwinklig zur Wandebene, so dass auch Zwängsspannungen vermieden und Windkräfte problemlos auf die tragenden Innenbauteile übertragen werden können.The anchor described allows with the simply trained Rigid anchor bolt rod shape on schedule horizontal installation or an installation perpendicular to Wall level, so that constraining stresses are avoided and Wind forces easily on the load-bearing interior components can be transferred.

Beim Einbau des Ankers ist darauf zu achten, dass die beiden Verankerungsglieder nicht nur rechtwinklig, sondern auch zueinander zentriert werden. Aus den Figuren 1 und 3 geht hervor, dass die Ankerstange 20 und die Ankerplatte 14 derart angeordnet sind, dass sie miteinander fluchten, also axial zueinander ausgerichtet sind. Dadurch ist gewährleistet, dass bei durch Winddruck erzeugten Kräften keine Biege- bzw. Knickbeanspruchungen auftreten können.When installing the anchor, make sure that the two anchoring links are not only centered at right angles, but also in relation to each other. It can be seen from FIGS. 1 and 3 that the anchor rod 20 and the anchor plate 14 are arranged such that they are aligned with one another, that is to say they are axially aligned with one another. This ensures that no bending or buckling stresses can occur under forces generated by wind pressure.

Durch den erfindungsgemässen Anker wird eine Nacharbeit an der Wärmedämmschicht vermieden, da diese lediglich von der Ankerstange durchdrungen wird. Reworking is carried out by the anchor according to the invention the thermal insulation layer avoided, since this is only from the Anchor rod is penetrated.

Die gerade Ankerstange gewährleistet, dass durch ungehindertes Anlegen einer Winkellehre ein exakt zur Wandebene senkrechter Einbau möglich ist. Durch eine kontrollierbare Montage wird eine Schräglage vermieden.The straight anchor rod ensures that by unimpeded Apply an angle gauge exactly to the wall level vertical installation is possible. Through a controllable Installation prevents an inclined position.

Wenn die Ankerstange im Profilkörper 10 drehbar ist, kann auf eine Drehbarkeit der Ankerplatte 14 im Profilkörper 10 verzichtet werden.If the anchor rod in the profile body 10 can be rotated, the anchor plate 14 can be dispensed with in the profile body 10 .

Der erfindungsgemässe Anker verhindert einerseits Rissbildungen im Mauerwerk und ermöglicht andererseits die Verwendung relativ dünner Aussenschalen.The anchor according to the invention prevents crack formation on the one hand in the masonry and on the other hand allows use relatively thin outer shells.
