Abstract

A spacer, such as is used, for example, for transmitting tensile force between a building wall and a wall element, for example a facade, placed in front of it, consists of a bar-shaped or band-shaped element made of spring material. Starting from one end of the spacer, this element is bent over a portion forming a part length of this spacer, in such a way that this portion projects in different directions radially above the longitudinal extension of the element. The spacer can be knocked with the abovementioned portion into a bore of the building wall, this portion then being held in the bore of the building wall by a clamping fit. A part length of the spacer projecting beyond the building wall is tied into the wall element placed in front of it. This provides in an especially simple way a bond between the building wall and preceding wall element which absorbs tensile forces. <IMAGE>

Description

Die Erfindung bezieht sich auf eine Verbindung zwischen zwei Gebäudeelementen unter Verwendung von Luftschichtankern gemäß Oberbegriff Patentanspruch 1 oder 3. Weiterhin bezieht sich die Erfindung auch auf einen Luftschichtanker zur Verwendung bei einer solchen Gebäudeverbindung gemäß Oberbegriff Patentanspruch 5 oder 6.The invention relates to a connection between two building elements using air-layer anchors according to the preamble of claim 1 or 3. Furthermore, the invention also relates to an air-layer anchor for use in such a building connection according to the preamble of claim 5 or 6.

Verbindungen zwischen Gebäudeelementen, beispielsweise zwischen einer Gebäudewand und einem vorgestellten Wandelement, z.B. einer Fassade sind bekannt. Zur Anbindung des vorgestellten Wandelementes, insbesondere auch zur Zugkraftübertragung werden sogenannte Luftschichtanker verwendet.Connections between building elements, for example between a building wall and a wall element presented, e.g. a facade are known. So-called air-layer anchors are used to connect the wall element presented, in particular also for the transmission of tensile force.

Speziell bekannt ist eine Verbindung zwischen Gebäudeelementen, bei der die Luftschichtanker jeweils von einem bandförmigen Element aus Federstahl gebildet sind (Siehe CH-A-643 024). Jeder als Federanker ausgebildete Luftschichtanker ist dabei an den beiden Enden gewellt und im mittleren Abschnitt verdrillt ausgeführt. Die beiden Enden jedes Luftschichtankers werden in jeweils einem der beiden Gebäudeelemente durch Einmörteln verankert. Diese Art der Verankerung ist relativ aufwendig und setzt insbesondere auch voraus, daß das Erstellen der beiden Gebäudeelemente gleichzeitig erfolgt, zumindest jedoch beim Erstellen eines der beiden Gebäudeelemente dort die Feder- bzw. Luftschichtanker bereits vorbereitet werden.A connection between building elements is particularly known, in which the air-layer anchors are each formed by a band-shaped element made of spring steel (see CH-A-643 024). Each air-layer anchor designed as a spring anchor is corrugated at both ends and is twisted in the middle section. The two ends of each air layer anchor are anchored in one of the two building elements by mortaring. This type of anchoring is relatively complex and in particular also presupposes that the two building elements are created simultaneously, but at least when the one of the two building elements is created, the spring or air-layer anchors are already prepared there.

Durch den verdrillten mittleren Abschnitt ist jeder Luftschichtanker axial federnd und daher auch nicht als axial einschlagbares Element ausgebildet.Due to the twisted middle section, each air layer anchor is axially resilient and therefore not designed as an axially impactable element.

Bekannt ist weiterhin eine Dübelverbindung zwischen Bauteilen aus spröden Stoffen (DE-C-915 732) und dabei konkret zwischen Platten und Randleisten. Für die Verbindung zwischen zwei Gebäudeelementen ist diese bekannte Dübelverbindung weder vorgesehen, noch geeignet.Also known is a dowel connection between components made of brittle substances (DE-C-915 732) and specifically between plates and edge strips. This known dowel connection is neither provided nor suitable for the connection between two building elements.

Aufgabe der Erfindung ist es, eine vereinfachte Verbindung zwischen zwei Gebäudeelementen sowie einen hierfür geeigneten Luftschichtanker aufzuzeigen.The object of the invention is to demonstrate a simplified connection between two building elements and a suitable air layer anchor.

Zur Lösung dieser Aufgabe ist eine Verbindung zwischen zwei Gebäudeteilen entsprechend dem kennzeichenden Teil des Patentanspruches 1 oder 3 sowie ein Luftschichtanker entsprechend dem kennzeichnenden Teil des Patentanspruches 5 bzw. 6 ausgebildet.To solve this problem, a connection between two parts of the building is formed according to the characterizing part of claim 1 or 3 and an air layer anchor according to the characterizing part of claim 5 or 6.

Bei der Realisierung der erfindungsgemäßen Verbindung, beispielsweise bei der Errichtung eines Wandelementes vor einem bestehenden Baukörper (Wand usw.) wird unter Verwendung des erfindungsgemäßen Luftschichtankers so vorgegangen, daß in den bestehenden Baukörper Bohrungen eingebracht werden, in die dann die als einschlagbare Elemente ausgebildeten Luftschichtanker mit ihrem einen Ende voraus so eingeschlagen werden, daß sie mit den wellenartigen Bereichen gegen die Innenfläche der betreffenden Bohrung federnd angedrückt anliegen, so daß der Luftschichtanker in der betreffenden Bohrung durch die wellenartigen Bereiche ohne Verwendung von Dübeln in dem bereits bestehenden Baukörper durch Klemmsitz verankert sind. Mit ihren über den Baukörper vorstehenden anderen Enden werden die Luftschichtanker dann in das zu errichtende, vorgesetzte Wandelement eingebettet.When realizing the connection according to the invention, for example when erecting a wall element in front of an existing structure (wall, etc.), the air-layer anchor according to the invention is used in such a way that holes are drilled in the existing structure, into which the air-layer anchors designed as foldable elements are then inserted one end ahead are driven in such a way that they resiliently press against the inner surface of the hole in question with the wave-like areas, so that the air-layer anchor is anchored in the hole in question through the wave-like areas without the use of dowels in the existing structure by means of a clamp fit. With their other ends projecting above the structure, the air-layer anchors are then embedded in the wall element to be erected.

Bei der Erfindung ist es nicht erforderlich, die Luftschichtanker bereits beim Erstellen desjenigen Baukörpers vorzusehen, vor dem das vorgesetzte Wandelement errichtet werden soll. Vielmehr kann bei der Erfindung das Verankern der Luftschichtanker in den bereits bestehenden Baukörper erst dann erfolgen, wenn das vorgesetzte Wandelement tatsächlich errichtet wird.In the invention, it is not necessary to provide the air-layer anchors already when creating the structure in front of which the front wall element is to be erected. Rather, the anchoring of the invention Air-layer anchors in the existing building only take place when the front wall element is actually erected.

Bei der Erfindung sind auch keine zusätzlichen Dübel zur Verankerung des Luftschichtankers erforderlich. Die zur Verankerung eines Luftschichtankers dienende Bohrung kann somit bei vorgegebenen Querschnitt des Luftschichtankers wesentlich kleiner gewählt werden, als dies beispielsweise bei einer Dübelbefestigung der Fall wäre.In the invention, no additional dowels are required for anchoring the air layer anchor. The bore serving for anchoring an air layer anchor can thus be chosen to be substantially smaller for a given cross section of the air layer anchor than would be the case, for example, with a dowel attachment.

Der Federstahl ist so gewählt, daß er eine ausreichende Verankerung sicherstellt. Der Federstahl ist bevorzugt ein nicht rostender Stahl. Im einfachsten Fall ist der erfindungsgemäße Luftschichtanker aus einer Länge eines Drahtes aus Federstahl hergestellt. Besteht der Luftschichtanker aus einem bandförmigen Material, so ist dessen Breite höchstens gleich, bevorzugt jedoch etwas kleiner als der Durchmesser der zur Verankerung dienenden Bohrungen.The spring steel is selected so that it ensures adequate anchoring. The spring steel is preferably a stainless steel. In the simplest case, the air layer anchor according to the invention is made from a length of wire made of spring steel. If the air-layer anchor consists of a band-shaped material, its width is at most the same, but is preferably somewhat smaller than the diameter of the bores used for anchoring.

Weiterbildungen der Erfindung sind Gegenstand der Unteransprüche.Developments of the invention are the subject of the dependent claims.

Die Erfindung wird im folgenden anhand der Figuren an Ausführungsbeispielen näher erläutert. Es zeigen:

The invention is explained in more detail below with reference to the figures using exemplary embodiments. Show it:
Fig. 1
in partial representation and in cross section, a building wall and a building facade in front together with an air layer anchor according to the invention;
Fig. 2
a representation similar to FIG. 1, but together with a further embodiment of the air layer anchor according to the invention.

In der Figur 1 ist 1 eine Gebäudeaußenmauer, die beispielsweise aus Beton hergestellt ist. An der Außenseite der Gebäudemauer 1 ist eine Vorsatz-Mauer bzw. Fassade 2 vorgesehen, die beispielsweise aus Klinker- oder Mauersteinen durch Aufmauern unter Verwendung von Mörtel hergestellt ist. Um vor allem die notwenige Zugkraftübertragung zwischen der Gebäudemauer 1 und der Fassade 2 zu erreichen, ist eine Vielzahl von Luftschichtankern 3 vorgesehen, von denen jeder, jeweils mit einer Teillänge, d.h. mit der in der Figur 1 linken Teillänge in der Geäudemauer 1 verankert und mit der über die der Fassade 2 zugewendete Seite der Gebäudewand 1 vorstehenden Länge im Mörtelbett der Fassade 2 eingebettet ist. Der Luftschichtanker 3 ist bei der dargestellten Ausführungsform von einem stabförmigen Element 4, d. h. von einer Länge eines Drahtes aus Federstahl, bevorzugt aus nicht rostendem Stahl mit Federstahleigenschaften gebildet, wobei dieses Element 4 ausgehend von dem in der Figur 1 linken Ende einen geradlinig verlaufenden Teilabschnitt 4ʹ, daran anschließend einen wellenartig gebogenen Teilabschnitt 4ʺ und daran anschließend einen wiederum geradlinig verlaufenden Teilabschnitt 4‴ aufweist, dessen Länge bei der dargestellten Ausführungsform größer ist als die Längen der Teilabschnitte 4ʹ und 4ʺ, aber auch größer ist als die Summen der Längen der Teilabschnitte 4ʹ und 4ʺ. Die beiden Teillängen 4ʹ und 4‴, die auch die beiden Enden des Luftschichtankers 3 bilden, liegen mit ihren Längserstreckungen achsgleich miteinander und bilden mit ihren Längserstreckungen die Längsachse L des Luftschichtankers 3.In FIG. 1, 1 is an outer wall of the building, which is made of concrete, for example. On the outside of the building wall 1, a facing wall or facade 2 is provided, which is produced, for example, from clinker bricks or masonry stones by bricking up using mortar. In order to achieve above all the necessary transmission of tractive force between the building wall 1 and the facade 2, a large number of air-layer anchors 3 are provided, each of which is anchored in the building wall 1 and each with a partial length, ie with the partial length on the left in FIG the length projecting over the side of the building wall 1 facing the facade 2 is embedded in the mortar bed of the facade 2. The air layer anchor 3 is formed in the illustrated embodiment from a rod-shaped element 4, ie from a length of wire made of spring steel, preferably of stainless steel with spring steel properties, this element 4 starting from the left end in FIG. 1, a rectilinear section 4 ' , followed by a wave-like curved section 4ʺ and then a straight section 4‴, the length of which in the illustrated embodiment is greater than the lengths of the sections 4ʹ and 4ʺ, but also greater than the sum of the lengths of the sections 4ʹ and 4ʺ. The two partial lengths 4ʹ and 4 ‴, which also form the two ends of the air-layer anchor 3, lie with their longitudinal extensions coaxially with one another and form the longitudinal axis L of the air-layer anchor 3 with their longitudinal extensions.

Das den Luftschichtanker 3 bildende Element 4 ist im Bereich des Teilabschnittes 4ʺ so geformt, daß in diesem Teilabschnitt ausgehend vom Teilabschnitt 4ʹ in Längsrichtung L aufeinanderfolgend insgesamt drei halbwellenartige Bereiche 5, 6 und 7 gebildet sind, an denen das Element 4 in jeweils entgegengesetzter Richtung über die Längsachse L wegsteht, und zwar derart, daß in der Zeichenebene der Figur 1 der Bereich 5 nach oben , der sich hieran anschließende Bereich 6 nach unten und der daran anschließende Bereich 7 wieder nach oben über die Längsachse L wegstehen. Alle halbwellenartigen Bereiche 5, 6 und 7 liegen in einer gemeinsamen Ebene, die die Zeichenebene der Figur 1 bildet und auch die Längsachse L einschließt.The element 4 forming the air-layer anchor 3 is shaped in the region of the section 4ʺ so that in this section, starting from the section 4ʹ in the longitudinal direction L, a total of three half-wave-like areas 5, 6 and 7 are formed, at which the element 4 is in the opposite direction the longitudinal axis L protrudes in such a way that in the drawing plane of FIG. 1 the area 5 projects upwards, the region 6 adjoining it downwards and the adjoining area 7 again projects upwards over the longitudinal axis L. All half-wave-like areas 5, 6 and 7 lie in a common plane which forms the plane of the drawing in FIG. 1 and also includes the longitudinal axis L.

Zur Verankerung des Luftschichtankers 3 in der Gebäudewand 1 ist in diese eine zur Fassade 2 hin offene Bohrung 8 eingebracht, die einen Durchmesser D sowie eine Länge bzw. Tiefe T aufweist. Der Durchmesser D der Bohrung 8 ist kleiner als der Abstand, den die am weitesten außen liegenden Punkte (Maximas) zweier aufeinanderfolgender Bereiche 5 - 7 in Richtung senkrecht zur Längsachse L voneinader besitzen, d. h. also kleiner als die Summe der Abstände, die die äußeren Punkte (Maximas) der Bereiche 5 und 6 bzw. 6 und 7 von der Längsachse L aufweisen. Die Tiefe T der Bohrung 8 ist etwas größer als der Abstand, den der am weitesten außen liegende Punkt des Bereiches 7 von dem freien Ende des Teilabschnittes 4ʹ in Richtung der Längsachse L aufweist. Durch die beschriebene Ausbildung sowie durch die Herstellung aus Federstahl bzw. aus federndem nicht rostendem Stahl kann der Luftschichtanker 3 mit dem Teilabschnitt 4ʹ voraus in die Bohrung 8 eingesetzt und in diese mit Hilfe eines geeigneten Werkzeugs (z. B. Hammer) eingeschlagen werden, so daß der Luftschichtanker 3 dann mit seinem wellenartig gebogenen Teilabschnitt 4ʺ in der Bohrung 8 durch Klemmsitz zuverlässig dadurch verankert ist, daß die Bereiche 5 - 7 federn bzw. angepresst gegen die Innenfläche der Bohrung anliegen, und zwar an einem inneren, von dem Bereich 5 und einem äußeren, von dem Bereich 7 gebildeten Anlagepunkt auf der einen Seite der Achse der Bohrung und auf der anderen Seite dieser Achse an einem dazwischenliegenden, vom Bereich 6 gebildeten Anlagepunkt, der gegenüber den beiden vorgenannten Anlagepunkten bezogen auf die Achse der Bohrung 8 um 180° versetzt ist. Bei in dieser Weise in der Gebäudewand 1 verankerten Luftschichtanker 3 liegt dessen Längsachse L in etwa achsgleich mit der Achse der Bohrung 8.For anchoring the air-layer anchor 3 in the building wall 1, a hole 8, which is open toward the facade 2 and has a diameter D and a length or depth T, is introduced into the wall 1. The diameter D of the bore 8 is smaller than the distance that the outermost points (maximas) of two successive areas 5 - 7 have in the direction perpendicular to the longitudinal axis L of each other, that is to say smaller than the sum of the distances between the outer points (Maximas) of areas 5 and 6 or 6 and 7 from the longitudinal axis L. The depth T of the bore 8 is somewhat greater than the distance which the outermost point of the region 7 has from the free end of the section 4 'in the direction of the longitudinal axis L. Due to the described design and the manufacture of spring steel or resilient stainless steel, the air-layer anchor 3 can be inserted with the partial section 4ʹ ahead into the bore 8 and hammered into it with the aid of a suitable tool (e.g. hammer) that the air-layer anchor 3 is then anchored reliably with its wave-like bent section 4ʺ in the bore 8 by a clamp fit in that the areas 5 - 7 resiliently or pressed against the inner surface of the bore, to an inner, from the area 5 and an outer contact point formed by the region 7 on one side of the axis of the Bore and on the other side of this axis at an intermediate contact point formed by the area 6, which is offset by 180 ° relative to the two aforementioned contact points with respect to the axis of the bore 8. In the case of air layer anchors 3 anchored in the building wall 1 in this way, its longitudinal axis L lies approximately coaxially with the axis of the bore 8.

Um das Einschlagen des Luftschichtankers 3 in die Bohrung 8 zu vereinfachen, kann der Bereich 5 so ausgebildet sein, daß dessen maximaler Abstand von der Längsachse L bei noch nicht in die Bohrung 8 eingebrachtem Luftschichtanker 3 etwas kleiner ist als der entsprechende Abstand des Bereiches 6.In order to simplify the driving of the air layer anchor 3 into the bore 8, the region 5 can be designed such that its maximum distance from the longitudinal axis L when the air layer anchor 3 is not yet introduced into the bore 8 is somewhat smaller than the corresponding distance of the region 6.

Bei einer praktischen Ausbildung beträgt der Durchmesser D der Bohrung 8 etwa 5mm, während die Tiefe T der Bohrung 8 in der Größenordnung von 40mm liegt. Hierbei können Zugkräfte bis zu 200kg über den Luftschichtanker 3 zwischen der Gebäudewand 3 und Fassade 2 übertragen werden.In a practical embodiment, the diameter D of the bore 8 is approximately 5 mm, while the depth T of the bore 8 is of the order of 40 mm. Here tensile forces up to 200kg can be transmitted via the air layer anchor 3 between the building wall 3 and facade 2.

Die Vorteile des Luftschichtankers 3 bestehn vor allem darin, daß die bisher notwendige Dübelbefestigung des Luftschichtankers an der Gebäudewand 1 entfällt, wodurch ein wesentlich kleiner Durchmesser D für die Bohrung 8 (5mm anstelle von 8mm) ausreichend ist und sich auch eine Vereinfachung der Verankerung des Luftschichtankers 3 in der Gebäudemauer 1 sowie eine höhere Zuverlässigkeit und Lebensdauer für diese Verankerung ergeben. Weiterhin läßt sich durch den Luftschichtanker 3 auch eine im Vergleich zu bekannten Luftschichtankern wesentlich verbesserte Zugkraftübertragung erreichen.The advantages of the air-layer anchor 3 consist primarily in the fact that the previously required dowel fastening of the air-layer anchor to the building wall 1 is no longer required, which means that a much smaller diameter D is sufficient for the bore 8 (5 mm instead of 8 mm) and also simplifies the anchoring of the air-layer anchor 3 in the building wall 1 as well as a higher reliability and service life for this anchoring. Furthermore, the air layer anchor 3 can also achieve a significantly improved tensile force transmission compared to known air layer anchors.

In der Figur 2 sind wiederum die Gebäudeaußenwand 1 sowie die Fassade 2 teilweise im Querschnitt wiedergegeben und zwar zusammen mit einem Luftschichtanker 3ʹ, der von einem stabförmigen Element 9, d.h. von einer Länge eines Drahtes aus Federstahl, bevorzugt aus nichtrostendem Stahl mit Federeigenschaften gebildet ist, wobei dieses Element 9 ausgehend von dem in der Figur 2 linken Ende einen geradlinig verlaufenden Teilabschnitt 9ʹ, der in der Fassade 2 (z.B. in einer Mörtelfuge dieser Fassade) verankert ist und demnach dem Teilabschnitt 4‴ des Luftschichtankers 3 entspricht, daran anschließend eine ebenfalls geradlinig verlaufenden Teilabschnitt 9ʺ, der an seinem, das in der Figur 2 linke Ende des Luftschichtankers 3ʹ bildenden Ende über einen Übergangsbereich 9‴ in einen Teilabschnitt 9ʹ‴ übergeht. An dem Übergangsbereich 9‴ ist das Element 9 bzw. der dieses Element bildende Draht um ca. 180° derart umgebogen, daß dieser Draht dann anschließend im Teilabschnitt 9ʹ‴ in Richtung auf den Teilabschnitt 9ʹ bzw. das dortige rechte Ende des Luftschichtankers 3ʹ zurückgeführt ist. Während die Teilabschnitte 9ʹ und 9ʺ in der Längsachse L des Luftschichtankers 3ʹ liegen bzw. diese Längsachse bilden, ist der Teilabschnitt 9ʹ‴ derart gebogen, daß er den Teilabschnitt 9ʺ wendel- oder schraubenartig umschließt.In FIG. 2, the outer wall 1 of the building and the facade 2 are again partially shown in cross-section, together with an air-layer anchor 3ʹ, which is formed by a rod-shaped element 9, ie a length of wire made of spring steel, preferably of stainless steel with spring properties, this element 9 starting from the left end in FIG. 2 a straight line running section 9ʹ, which is anchored in the facade 2 (e.g. in a mortar joint of this facade) and accordingly corresponds to the section 4 ‴ of the air-layer anchor 3, followed by a likewise straight-line section 9ʺ, which at its left end in Figure 2 of the air layer anchor 3ʹ forming end passes over a transition region 9 ‴ in a section 9abschnitt ‴. At the transition region 9 ‴, the element 9 or the wire forming this element is bent over by approximately 180 ° such that this wire is then returned in the partial section 9abschnitt ʹ in the direction of the partial section 9ʹ or the right end there of the air layer anchor 3ank . While the sections 9ʹ and 9ʺ lie in the longitudinal axis L of the air layer anchor 3ʹ or form this longitudinal axis, the section 9ʹ ‴ is bent such that it encloses the section 9ʺ helically or helically.

Zum Verankern des Luftschichtankers 3 in der Gebäudewand 1 wird dieser mit seinem vom Übergangsbereich 9‴ gebildeten Ende voraus in die in der Gebäudewand 1 vorgesehene Bohrung 8 eingeschlagen, wobei der Durchmesser D dieser Bohrung 8 etwas kleiner ist als der Außendurchmesser, den der Luftschichtanker 3ʹ im Bereich des Teilabschnittes 9ʹ‴ besitzt, so daß der Luftschichtanker 3ʹ mit seinem Teilabschnitt 9ʹ‴ federnd gegen die Innenfläche der Bohrung 8 anliegt und dadurch in dieser Bohrung durch Klemmsitz sicher verankert ist. Bei in der Bohrung 8 verankertem Luftschichtanker 3ʹ sind von dieser Bohrung 8 die Teilabschnitte 9ʺ und 9ʹ‴ sowie der Übergangsbereich 9‴ aufgenommen.For anchoring the air-layer anchor 3 in the building wall 1, this end with its end formed by the transition region 9 ‴ is driven into the hole 8 provided in the building wall 1, the diameter D of this hole 8 being slightly smaller than the outside diameter that the air-layer anchor 3 'im Area of the section 9ʹ ‴ has, so that the air layer anchor 3ʹ rests with its section 9ʹ ‴ resiliently against the inner surface of the bore 8 and is thereby securely anchored in this bore by a clamp fit. When the air-layer anchor 3 ver is anchored in the bore 8, the subsections 9ʺ and 9ʹ ‴ and the transition region 9 ‴ are received by this bore 8.

Bei auf den Luftschichtanker 3ʹ in Längsrichtung L wirkenden Zugkräften zwischen der Gebäudewand 1 und der Fassade 2 (Pfeil A) verkrallt sich nicht nur das dem Übergangsbereich 9‴ entfernt liegende freie Ende 10 des Teilabschnittes 9ʹ‴ an der Wandung der Bohrung 8 im Material der Gebäudewand 1, sondern hierbei werden auf den wendelartig gebogenen Teilabschnitt 9ʹ‴ auch Kräfte ausgeübt, die im Sinne eines Vergrößerns des Außendurchmessers dieses wendelartigen Teilbereichs 9ʹ‴ wirken und damit die Verankerung des Luftschichtankers 3ʹ in der Bohrung 8 noch erhöhen, so daß sich für den Luftschichtanker 3ʹ eine besonders zuverlässige Verankerung in der Gebäudewand 1 ergibt, die (Verankerung) insbesondere auch bei wechselnden, vom Luftschichtanker 3ʹ übertragenen Lasten nicht verlorengeht.In the case of tensile forces acting on the air layer anchor 3 Längs in the longitudinal direction L between the building wall 1 and the facade 2 (arrow A), not only the free end 10 of the section 9ʹ lieg which is located away from the transition area 9‴ is clawed against the wall of the bore 8 in the material of the building wall 1, but in this case forces are also exerted on the helically curved section 9ʹ ‴, which act in the sense of increasing the outer diameter of this helical section 9ʹ ‴ and thus anchoring the Air layer anchor 3ʹ in the hole 8 still increase, so that there is a particularly reliable anchoring in the building wall 1 for the air layer anchor 3ʹ, which (anchoring) is not lost, especially with changing loads transmitted by the air layer anchor 3ʹ.

Vereinfacht kann der Luftschichtanker 3ʹ auch so ausgebildet sein, daß der Teilabschnitt 9ʹ‴ ähnlich dem Teilabschnitt 4ʺ des Luftschichtankers 3 wellenartig gebogen ist und dann den Bereichen 5, 6 und 7 des Luftschichtankers 3 entsprechende Bereiche 11, 12 und 13 bildet, mit denen der Teilabschnitt 9ʹ‴ zusätzlich zu dem Ende 10 gegen die Innenfläche der Bohrung 8 federnd anliegt. Der wellenförmige Teilabschnitt 9ʹ‴ ist dann seitlich von dem Teilabschnitt 9ʺ vorgesehen. Auch bei dieser Ausführung wirken Zugkräfte zwischen der Gebäudewand 1 und der Fassade 2 (Pfeil A) im Sinne einer Vergrößerung der Wellung des Teilabschnittes 9ʹ‴ und führen damit zu einer noch festeren Verankerung des Luftschichtankers 3 in der Bohrung 8.Simplified, the air-layer anchor 3ʹ can also be designed such that the section 9ʹ ‴, like the section 4ʺ of the air-layer anchor 3, is curved in a wave-like manner and then forms the areas 5, 6 and 7 of the air-layer anchor 3 with corresponding areas 11, 12 and 13 with which the section 9ʹ ‴ rests resiliently against the inner surface of the bore 8 in addition to the end 10. The wavy section 9ʹ ‴ is then provided laterally from the section 9ʺ. In this embodiment, too, tensile forces act between the building wall 1 and the facade 2 (arrow A) in the sense of increasing the corrugation of the partial section 9ʹ ʹ and thus lead to an even firmer anchoring of the air layer anchor 3 in the bore 8.

Die Erfindung wurde voranstehand an Ausführungsbeispielen beschrieben. Es versteht sich, daß weitere Änderungen sowie Abwandlungen möglich sind, ohne daß dadurch der der Erfindung zugrundeliegende Erfindungsgedanke verlassen wird. Insbesondere ist die Anwendung des Luftschichtankers gemäß der Erfindung nicht auf die Verankerung von Fassaden beschränkt, sondern dieser kann grundsätzlich überall dort eingesetzt werden, wo vor einer Wand ein weiteres Bauteil errichtet werden soll, welches mit dieser Wand zur Aufnahme von Zugkräften verbunden werden muß.The invention has been described above using exemplary embodiments. It goes without saying that further changes and modifications are possible without thereby departing from the inventive idea on which the invention is based. In particular, the use of the air-layer anchor according to the invention is not limited to anchoring facades, but can basically be used wherever another component is to be erected in front of a wall, which must be connected to this wall to absorb tensile forces.
