Description

Die Erfindung betrifft einen Luftschichtanker für zweischaliges Mauerwerk aus Außenschale, Luftschicht und Innenschale mit einem langgestreckten Mittelabschnitt zum Überbrücken der Luftschicht, einen gefaltetem Abschnitt zum Einmauern in die Außenschale des Mauerwerkes und einem flachen Abschnitt zum Einmauern in die Innenschale des Mauerwerkes.The invention relates to an air layer anchor for clam shell masonry of outer shell, air layer and inner shell with an elongated central portion for bridging the air layer, a folded section for walling into the outer shell of the masonry and a flat section for walling into the inner shell of the masonry.

Solche Luftschichtanker sind zum Beispiel aus der DE 37 175 63 C2 (dort als "Hohlmaueranker" bezeichnet) und der DE 297 18 804 U1 bekannt. Von letzterem Luftschichtanker geht die vorliegende Neuerung aus.Such air layer anchors are for example from DE 37 175 63 C2 (referred to as "hollow wall anchor") and the DE 297 18 804 U1 known. From the latter air layer anchor the present innovation goes out.

Beim Stand der Technik nach dem DE 297 18 804 U1 weist der gefaltete Abschnitt an seinen beiden seitlichen Kanten Ausnehmungen zur Aufnahme von Mörtel auf. Bei diesem Stand der Technik ist der in der vorliegenden Anmeldung als "gefalteter Abschnitt" bezeichnete Teil des Luftschichtankers als "zweiter flacher Endabschnitt bezeichnet. Den Einbau des Luftschichtankers mit den genannten Abschnitten in das zweischalige Mauerwerk zeigt zum Beispiel dieses deutsche Gebrauchsmuster.In the prior art after the DE 297 18 804 U1 For example, the folded portion has recesses for receiving mortar on its two lateral edges. In this prior art, the part of the air layer anchor referred to as "folded section" in the present application is referred to as the "second flat end section." For example, this German utility model shows the installation of the air layer anchor with said sections into the two-shell masonry.

Der Erfindung liegt die Aufgabe zugrunde, einen Luftschichtanker der eingangs genannten Art so weiterzuentwickeln, dass mit geringem Herstellungsaufwand, insbesondere hinsichtlich des Materials und der Werkzeuge, ein stabiler und im Baubetrieb gut handhabbarer Luftschichtanker zur Verfügung steht.The invention has for its object to further develop an air-layer anchor of the type mentioned so that with low manufacturing costs, especially in terms of material and tools, a stable and well-manageable in construction operation air layer anchor is available.

Ein diese Aufgabe lösender Luftschichtanker ist im Patentanspruch 1 beschrieben. Der flache Abschnitt wird üblicherweise in die Innenschale des Mauerwerkes eingemauert, während der gefaltete Abschnitt in die Außenschale eingefügt ist.A solving this task air-layer anchor is described in claim 1. The flat portion is usually walled into the inner shell of the masonry, while the folded portion is inserted into the outer shell.

Bevorzugte Ausgestaltungen der Erfindung werden in den abhängigen Ansprüchen definiert.Preferred embodiments of the invention are defined in the dependent claims.

Insgesamt ist der Luftschichtanker in Übereinstimmung mit dem oben genannten Stand der Technik nach dem DE 297 18 804 U1 aus einem einzigen Stück Flachstahl (Stahlblech) geformt, wobei das Stück Stahlblech im Mittelabschnitt rund gebogen und im gefalteten Abschnitt flach gefalzt ist, d.h. die beiden Kanten des langgestreckten Stahlbleches werden in diesem Bereich nach innen geschlagen, sodass sie sich etwa in der Mitte berühren und flach gepresst. In diesem gefalteten Abschnitt sind, in Übereinstimmung mit dem oben genannten Stand der Technik, bevorzugt an den Seitenrändern Ausnehmungen vorgesehen, in die zur besseren Verankerung Mörtel oder Kleber oder dergleichen eingreift.Overall, the air layer anchor in accordance with the above-mentioned prior art after DE 297 18 804 U1 formed from a single piece of flat steel (sheet steel), wherein the piece of sheet steel in the middle section is bent round and folded flat in the folded section, ie the two edges of the elongated steel sheet are struck in this area inward, so that they touch approximately in the middle and pressed flat. In this folded portion, recesses are preferably provided on the side edges, in accordance with the above-mentioned prior art, in which engages for better anchoring mortar or adhesive or the like.

Gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ist im flachen Abschnitt, der üblicherweise in die Innenschale des Mauerwerkes eingemauert wird, eine sich quer zur Längsrichtung des Ankers erstreckende vierte Sicke ausgeformt, und zwar nahe der Auffaltung, mit der der runde Mittelabschnitt in den flachen Abschnitt übergeht, sodass im Bereich dieser Sicke der Anker leicht und ohne Bruchgefahr abgewinkelt werden kann. Ein so abgewinkelt in den Mörtel eingelegter Luftschichtanker kann nicht mehr herunterfallen, bevor die nächste Steinlage aufgesetzt wird. Auch bei nicht in gleicher Höhe liegenden Fugen von Außenschale und Innenschale ist diese leichte Biegbarkeit an der genannten Sicke von Vorteil.According to a further preferred embodiment of the invention is in the flat portion, which is usually walled into the inner shell of the masonry, a transversely extending to the longitudinal direction of the armature fourth bead formed, close to the unfolding, with the round center section merges into the flat portion so that in the region of this bead, the anchor can be angled easily and without risk of breakage. An air-layer anchor so angled into the mortar can no longer fall down before the next stone layer is put on. Even with not lying at the same height joints of outer shell and inner shell of this flexibility is easy to bend on the said bead.

Gemäß einer weiteren Ausgestaltung der Erfindung, sind zumindest im flachen Abschnitt des Ankers Sicken in U-Form ausgebildet, wobei die Basis des "U" dem runden Mittelabschnitt zugekehrt ist.According to a further embodiment of the invention, beads are formed in a U-shape at least in the flat portion of the armature, wherein the base of the "U" is facing the round central portion.

Gemäß der Erfindung wird der Bereich der Auffaltung vom Mittelabschnitt in den flachen Abschnitt durch eine erste Sicke verstärkt, die zum Beispiel "V"-förmig ist, wobei bevorzugt noch eine kurze dritte Sicke zentral und in Richtung der Längsachse des Luftschichtankers vorgesehen ist, die insbesondere in den Basisabschnitt der oben genannten "U"-förmigen Sicke übergehen kann.According to the invention, the area of the folding from the middle section into the flat section is reinforced by a first bead, which is for example "V" -shaped, whereby preferably a short third bead is provided centrally and in the direction of the longitudinal axis of the air layer anchor, in particular in the base portion of the above-mentioned "U" -shaped bead can go over.

Eine weitere Verstärkung der Stabilität des abgeflachten Abschnittes kann durch Abwinklung von dessen Seitenrändern erreicht werden.Further enhancement of the stability of the flattened portion can be achieved by bending its side edges.

Der gefaltete Abschnitt ist bevorzugt an seinem Ende zugespitzt, damit zum Beispiel ein Dämmstoff leichter auf den Luftschichtanker geschoben werden kann. Der gefaltete Abschnitt kann, wie oben ausgeführt ist, seitlich halbkreisförmige Ausnehmungen aufweisen, die bevorzugt zueinander auf beiden Seiten versetzt sind, wobei gemäß einer weiteren bevorzugten Ausgestaltung der Erfindung ein Bereich des gefalteten Abschnittes im Bereich von z.B. 1 bis 2 cm zur Verbesserung der Stabilität ohne Randausnehmungen gelassen wird. Auch kann in diesem Bereich zur weiteren Förderung der Stabilität eine zentrale Sicke vorgesehen sein, zum Beispiel durch Eindrücken einer Vertiefung an der Nahtstelle zwischen den beiden umgebogenen, aneinander anstoßenden Kanten des Stahlbleches.The folded portion is preferably tapered at its end, so that, for example, an insulating material can be easily pushed onto the air layer anchor. The folded portion may, as stated above, have laterally semicircular recesses which are preferably offset from one another on both sides, and according to a further preferred embodiment of the invention a portion of the folded portion is in the range of e.g. 1 to 2 cm is left to improve stability without Randausnehmungen. Also, in this area to further promote the stability of a central bead may be provided, for example by pressing a depression at the interface between the two bent, abutting edges of the steel sheet.

Gemäß der Erfindung ist eine zweite Sicke vorgesehen, die sich vom zylinderförmigen Mittelabschnitt über seinen Übergang bis in den gefalteten Abschnitt des Ankers erstreckt, d.h. diese Sicke ist sowohl im zylinderförmigen Mittelabschnitt, dem Übergang von diesem Abschnitt in den gefalteten Abschnitt und im gefalteten Abschnitt selbst ausgebildet. Hierdurch wird die Stabilität in diesem kritischen Übergangsbereich besonders gefördert.According to the invention a second bead is provided which extends from the cylindrical central portion via its transition to the folded portion of the anchor, i. this bead is formed both in the cylindrical central portion, the transition from this portion into the folded portion and in the folded portion itself. As a result, the stability in this critical transition region is particularly encouraged.

Eine weitere bevorzugte Ausgestaltung der Erfindung sieht vor, dass zur weiteren Förderung der Stabilität des insoweit besonders kritischen gefalteten Abschnittes dieser über einen Bereich von zum Beispiel 20 bis 40% seiner Längserstreckung, insbesondere 25 bis 35% seiner Längserstreckung, an den Seitenrändern keine Ausnehmungen aufweist.A further preferred embodiment of the invention provides that for further promotion of the stability of the so far particularly critical folded portion of this over a range of, for example, 20 to 40% of its longitudinal extent, in particular 25 to 35% of its longitudinal extent, at the side edges has no recesses.

Die beiden vorstehend genannten Maßnahmen führen dazu, dass der Anker eine sehr gute Steifigkeit aufweist, und zwar auch dann, wenn der Anker insgesamt relativ lang ist.The two measures mentioned above mean that the armature has a very good rigidity, even if the armature as a whole is relatively long.

Der vorstehend genannte Bereich des gefalteten Abschnittes ohne seitliche Aussparungen ermöglicht auch den Ausgleich von Toleranzen, die beim Hochziehen eines Klinkermauerwerkes auftreten können.
Nachfolgend wird ein Ausführungsbeispiel der Erfindung anhand der Zeichnung näher beschrieben.The above-mentioned area of the folded section without lateral recesses also makes it possible to compensate for tolerances that can occur when pulling up a brickwork.
An embodiment of the invention will be described in more detail with reference to the drawing.

Der Luftschichtanker 10 ist in Figur 1 in einer Seitenansicht dargestellt, d.h. in einer Ansicht in horizontaler Richtung, bezogen auf den Einbauzustand des Luftschichtankers in einem Mauerwerk. Ein doppelschaliges Mauerwerk mit Innenschale und Außenschale ist als solches gut bekannt und zum Beispiel im eingangs genannten Stand der Technik näher beschrieben ( DE 297 18 804 U1 ). Danach wird zum Beispiel der flache Abschnitt 14 des Luftschichtankers 10 in die Fugen einer Innenwand eingelegt und ein gefalteter Abschnitt 16 in die Fugen einer Außenschale des Mauerwerkes (nicht gezeigt). Der runde Mittelabschnitt 12 des Luftschichtankers überbrückt dann den Luftspalt zwischen Innenschale und Außenschale des Mauerwerkes.The air layer anchor 10 is in FIG. 1 shown in a side view, ie in a view in the horizontal direction, based on the installation state of the air layer anchor in a masonry. A double-shell masonry with inner shell and outer shell is well known as such and described in more detail, for example, in the aforementioned prior art ( DE 297 18 804 U1 ). Thereafter, for example, the flat portion 14 of the air layer anchor 10 is inserted into the joints of an inner wall and a folded portion 16 in the joints of an outer shell of the masonry (not shown). The round central portion 12 of the air layer anchor then bridges the air gap between the inner shell and outer shell of the masonry.

Der Luftschichtanker ist insgesamt aus einem einzigen Stück Flachstahl geformt. Der Flachstahl hat beim Ausführungsbeispiel eine Stärke von zum Beispiel 0,5 bis 0,6 mm. Dies ist dann auch die Stärke des Luftschichtankers im Bereich des flachen Abschnittes 14.The air layer anchor is formed overall from a single piece of flat steel. The flat steel in the embodiment has a thickness of, for example, 0.5 to 0.6 mm. This is then also the strength of the air layer anchor in the region of the flat section 14.

Insgesamt hat ein Luftschichtanker gemäß dem Ausführungsbeispiel zum Beispiel eine Länge von 36 cm. Die Breite im Bereich des flachen Abschnittes 14 kann 1,8 cm betragen und der Durchmesser im Bereich des kreiszylinderförmigen runden Abschnittes 12, in den das Stück Flachstahl gebogen ist, beträgt zum Beispiel etwa 0,6 cm. Das Stück Flachstahl ist im Bereich des gefalteten Abschnittes 16 bis zum Mittellinie gefaltet, sodass sich die Kanten an einer Nahtlinie 42 berühren (vgl. Figur 4), sodass die Breite des gefalteten Abschnittes 16 beim dargestellten Ausführungsbeispiel etwa 0,9 cm beträgt (die Zeichnungen sind also nicht maßstabsgerecht).Overall, an air layer anchor according to the embodiment, for example, a length of 36 cm. The width in the region of the flat portion 14 may be 1.8 cm and the diameter in the region of the circular cylindrical round portion 12, in which the piece of flat steel is bent, is for example about 0.6 cm. The piece of flat steel is folded in the region of the folded portion 16 to the center line, so that the edges on a seam line 42 touch (see. FIG. 4 ), so that the width of the folded portion 16 in the illustrated embodiment is about 0.9 cm (the drawings are therefore not to scale).

Gemäß Figur 2 geht der runde Mittelabschnitt 12 entlang einer Auffaltung 18 in den flachen Abschnitt 14 über. Im flachen Abschnitt 14 sind auf der Achse mehrere Löcher 20 in das Blech eingestanzt zur besseren Verankerung im Mörtel, Kleber oder dergleichen. Die beiden Seitenränder 22, 24 des flachen Abschnittes 14 sind leicht abgewinkelt, vgl. Figur 5. Der Mittelstreifen 26 des flachen Abschnittes 14 ist plan, vgl. ebenfalls Figur 5.According to FIG. 2 the round center section 12 merges along a fold 18 into the flat section 14. In the flat portion 14 a plurality of holes 20 are punched in the sheet for better anchoring in the mortar, adhesive or the like on the axis. The two side edges 22, 24 of the flat portion 14 are slightly angled, cf. FIG. 5 , The central strip 26 of the flat portion 14 is flat, cf. also FIG. 5 ,

Weiterhin zeigt Figur 2 im Bereich der Auffaltung 18 und im flachen Abschnitt 14 eine Reihe von Sicken 28-36, nämlich zwei Sicken (Vertiefungen) 30, 32, die sich parallel zur Längsrichtung des Ankers erstrecken, und zwar etwa zwischen der Mittelachse und den Rändern. Die beiden Sicken 30, 32 werden durch eine quer verlaufende Sicke 28 miteinander verbunden, sodass insgesamt die Sicken 28, 30, 32 eine "U"-Form bilden.Further shows FIG. 2 in the region of the fold 18 and in the flat portion 14 a series of beads 28-36, namely two beads (recesses) 30, 32 which extend parallel to the longitudinal direction of the armature, approximately between the central axis and the edges. The two beads 30, 32 are connected by a transverse bead 28 with each other, so that a total of the beads 28, 30, 32 form a "U" shape.

An der Basissicke 28 "der U"-Form erstreckt sich axial etwa mittig eine weitere kurze Sicke 34 hinein in die Auffaltung 18. Weiterhin wird die Auffaltung 18 durch eine "V"-förmige Sicke 36 weiter stabilisiert.At the base bead 28 "of the U" shape extends axially approximately centrally another short bead 34 into the fold 18. Furthermore, the fold 18 is further stabilized by a "V" shaped bead 36.

Die genannten Sicken 28-36 können zum Beispiel eine Tiefe von bis zum 1 mm aufweisen.The mentioned beads 28-36 may, for example, have a depth of up to 1 mm.

Im Bereich, wo die Auffaltung 18 in den flachen Abschnitt 14 übergeht sind auf beiden Seiten Ausnehmungen 44 vorgesehen, sodass die Abwinklung der Ränder 22, 24 erleichtert ist.In the area where the fold 18 merges into the flat portion 14 recesses 44 are provided on both sides, so that the bending of the edges 22, 24 is facilitated.

An der quer zur Längsrichtung des Ankers verlaufenden Sicke 28 lässt sich der runde Mittelabschnitt 12 leicht in Bezug auf den flachen Abschnitt 14 abwinkeln.At the transverse to the longitudinal direction of the armature extending bead 28, the circular central portion 12 can be angled slightly with respect to the flat portion 14.

Der gefaltete Abschnitt 16 hat an seinen beiden Rändern zueinander versetzte ("auf Lücke" stehende) Ausnehmungen 40 in Halbkreisform zur besseren Verankerung im Mörtel oder Kleber oder dergleichen. Im Bereich der Naht 42 zwischen den aneinander anstoßenden umgelegten Kanten des Stückes Stahlblech ist eine Sicke 46 eingepresst, und zwar so, dass die Ausbauchung der Sicke auf derjenigen Seite des gefalteten Abschnittes liegt, die keine Naht aufweist (in Figur 4 also wäre die Ausbauchung nach unten gerichtet).The folded portion 16 has at its two edges staggered ("gap" standing) recesses 40 in a semicircular shape for better anchoring in mortar or adhesive or the like. In the region of the seam 42 between the abutting folded edges of the piece of sheet steel, a bead 46 is pressed in such a way that the bulge of the bead lies on that side of the folded portion which has no seam (in FIG. 4 so the bulge would be directed downwards).

Wie Figur 2 weiter zeigt, erstrecken sich die seitlichen Ausnehmungen 40 im gefalteten Abschnitt 16 nicht ganz bis zum runden Abschnitt 12, vielmehr ist ein Bereich von zum Beispiel 1,5 bis 2,2 cm frei von Ausnehmungen in den Rändern. Dadurch wird der gefaltete Abschnitt in diesem Bereich stabiler und der Luftschichtanker ist bei unterschiedlichen Mauerwerken mit unterschiedlichen Abmessungen verwendbar.As FIG. 2 Further, the side recesses 40 in the folded portion 16 do not extend all the way to the round portion 12, but a range of, for example, 1.5 to 2.2 cm is free from recesses in the edges. As a result, the folded portion becomes more stable in this area and the air layer anchor can be used for different masonry with different dimensions.

Der Übergang vom runden Mittelabschnitt 12 in den gefalteten Abschnitt 16 ist relativ "weich", d.h. der Krümmungsradius des Bleches an der Stelle 48 ist relativ groß, zum Beispiel 10 cm oder größer.The transition from the round central portion 12 to the folded portion 16 is relatively "soft", i. the radius of curvature of the sheet at location 48 is relatively large, for example 10 cm or greater.
