B. an einer z. B. vertikalen Stütze z. B. aus Beton oder Stahl oder Holz einer Bautragkonstruktion angeordneten, vorzugsweise vertikal ausgerichteten Ankerschiene. Die Erfindung betrifft außerdem ein Porenbetonwandplattensystem aufweisend die Zuglaschen.The invention relates to an anchoring element of a stamped sheet metal part for an anchoring device in the form of a so-called pull tab for attachment of aerated concrete wall panels to one on a supporting part, for. B. at a z. B. vertical support z. B. concrete or steel or wood of a Bautragkonstruktion arranged, preferably vertically aligned anchor rail. The invention also relates to an aerated concrete wall panel system comprising the pull tabs.

Wandbauplatten aus Porenbeton weisen z. B. folgende Abmessungen auf: Dicke 125 bis > 250 mm, Breite 500 bis 750 mm, Länge 5000 bis > 7500 mm. Sie werden vor den Stützen einer Bautragkonstruktion hauptsächlich durch Winddruck- und -sogkräfte beansprucht, die von der Verankerungsvorrichtung in die Stützen eingeleitet werden müssen. Dazu werden unter anderem Verankerungselemente verwendet, die in bauseitig vorgegebene Ankerschienen eingehängt werden. Damit werden die Windlasten aufgenommen, die als Zugkräfte rechtwinklig zur Wandplattenebene wirken. Druckkräfte werden über direkten Kontakt zwischen Wandbauplatte und Tragkonstruktion abgeleitet.Wall panels made of aerated concrete have z. B. the following dimensions: thickness 125 to> 250 mm, width 500 to 750 mm, length 5000 to> 7500 mm. They are claimed before the supports of a Bautragkonstruktion mainly by Winddruck- and -sogkräfte that must be initiated by the anchoring device in the supports. For this purpose, among other anchoring elements are used, which are mounted in the field specified anchor channels. Thus, the wind loads are absorbed, which act as tensile forces perpendicular to the wall plate level. Compressive forces are derived via direct contact between the wallboard and the supporting structure.

Aus dem Gebrauchsmuster G 92 15 457 U1 ist eine Zuglasche bekannt, die als einstückiges Blechstanzteil ausgebildet ist und einen in einer Ankerschiene einsetzbaren Ankerkopf, einen sich an den Ankerkopf anschließenden schräg zur Plattenebene verlaufenden Verbindungssteg und ein sich an den Verbindungssteg anschließendes Nagelblech mit trapezförmigem Grundriss aufweist. Im Nagelblech sind kreisrunde Durchgangslöcher für den Durchgriff von in eine Porenbetonwandbauplatte einzutreibenden Nägeln z. B. Hohlnägeln vorgesehen, wie sie z. B. im Gebrauchsmuster G 92 15 458 U1 beschrieben werden.From the utility model G 92 15 457 U1 a pull tab is known, which is designed as a one-piece stamped sheet metal part and can be used in an anchor rail anchor head, an adjoining the anchor head obliquely to the plane of the plate connecting web and a subsequent to the connecting web nail plate with trapezoidal plan. In the nail plate are circular through holes for the penetration of to be recovered in a cellular concrete wallboard nails z. B. hollow nails provided as z. B. in the utility model G 92 15 458 U1 to be discribed.

In das Nagelblech ist eine Versteifungssicke eingebracht und die Nagellöcher sind ebenfalls gesickt. Außerdem ist der Nagelkopf umgefaltet.In the nail plate, a stiffening bead is introduced and the nail holes are also beaded. In addition, the nail head is folded.

Die bekannte einstückige Ausgestaltung eines Verankerungselements soll vorbekannte zweistückige Ausgestaltungen einer zuglasche verbessern, bei der lediglich der Ankerkopf mit dem Verbindungssteg einstückig und das Nagelblech als separates mit dem Verbindungssteg zu koppelndes Blechstanzteil ausgebildet sind.The known one-piece design of an anchoring element is intended to improve previously known two-piece embodiments of a zuglasche, in which only the anchor head with the connecting web in one piece and the nail plate are designed as separate with the connecting web to be punched sheet metal stamping.

Verankerungsvorrichtungen mit solchen Verankerungselementen sind für hohe Halterungskräfte bis z. B. 2,25 kN pro Verbindungselement vorgesehen.Anchoring devices with such anchoring elements are for high retention forces to z. B. 2.25 kN per connector provided.

Für geringere Haltekräfte, z. B. zwischen 0,70 und 1,15 kN pro Verankerungselement, werden einstückige Zuglaschen verwendet, die lediglich einen Ankerkopf und einen schräg zur Plattenebene verlaufenden Nagelsteg aufweisen.For lower holding forces, z. B. between 0.70 and 1.15 kN per anchoring element, one-piece pull tabs are used, which have only one anchor head and an angle extending to the plane of the board nail ridge.

Die bekannte einstückige Zuglasche für hohe Halterungskräfte erfordert insbesondere wegen der speziellen Raumform des Nagelblechs und des Ankerkopfs relativ viel Blechmaterial, und es fällt bei der Herstellung relativ viel Blechabfallmaterial an. Als Blechmaterial muss in der Regel Edelstahlblech verwendet werden, das teuer ist. Außerdem ist die Kraftübertragung, die im Nagelblech über die Nägel stattfindet, nicht optimal. Hinzu kommt, dass zusätzlich Sicken in das Nagelblech eingeformt werden müssen und Umfaltungen im Ankerkopf erforderlich sind.The well-known one-piece pull tab for high support forces requires a relatively large amount of sheet material, in particular because of the special spatial shape of the nail plate and the anchor head, and it is produced in the production of relatively much sheet metal waste material. As a sheet metal usually stainless steel sheet must be used, which is expensive. In addition, the power transmission that takes place in the nail plate on the nails, not optimal. In addition, in addition beads must be formed in the nail plate and folds in the anchor head are required.

Aufgabe der Erfindung ist, eine einstückige zuglasche und ein Wandplattensystem mit der Zuglasche zu schaffen, die eine unkomplizierte Raumform aufweist und materialsparend und abfallarm herstellbar ist, gleichwohl aber die vorbestimmten hohen Halterungskräfte in der Verankerungsvorrichtung weiterleiten kann, einfach in ein Wandplattensystem einbaubar ist und hohe Windlasten übertragen kann.The object of the invention is to provide a one-piece zuglasche and a wall plate system with the pull tab, which has a simple spatial form and material saving and low-waste produced, but nevertheless can pass on the predetermined high support forces in the anchoring device, is easy to install in a wall plate system and high wind loads can transfer.

Diese Aufgabe wird durch die Merkmale des Anspruchs 1 und 21 gelöst. Vorteilhafte Weiterbildungen der Erfindung werden in den Unteransprüchen gekennzeichnet.This object is solved by the features of claims 1 and 21. Advantageous developments of the invention are characterized in the subclaims.

Durch die neue Raumform der Zuglasche, insbesondere in Verbindung mit der besonderen Anordnung der Nagelöcher, gelingt es, eine Zuglasche zur Verfügung zu stellen, die hohe Haltekräfte bis zu 25 kN übertragen kann, wobei die einfache Raumform zudem relativ wenig Blechmaterial erfordert und einfach und materialsparend und abfallarm ausstanzbar ist.The new spatial form of the pull tab, especially in conjunction with the special arrangement of Nagelöcher, it is possible to provide a pull tab available that can transmit high holding forces up to 25 kN, the simple spatial form also requires relatively little sheet material and easy and material-saving and is punched out low waste.

B. transverse center region of the end faces 11 of the support members 12, 12 a is in the longitudinal direction of the support elements vertically extending, undercut C-profile anchor rail 10, z. B. made of metal, for. B. embedded in the case of the concrete column or welded in the case of the double-T-beam, the vertical opening slot opens at the surface of the end faces 11. The anchor rail 10 may also be outside on end faces 11 of the column, or z. As a square steel prop, or a wooden beam construction may be arranged.

Gegen die Stirnseite 11 sind für eine sog. Mittelverankerung zwei vertikal ausgerichtete Porenbetonplatten 6, 7 gesetzt, wobei sich die Fuge 8 zwischen den beiden Platten 6, 7 in der Quermitte der Ankerschiene 10 und damit auch in der Quermitte der Tragelemente 12, 12a befindet.Against the end face 11, two vertically oriented aerated concrete slabs 6, 7 are set for a so-called.

Dabei ist die Ausgestaltung des Ankerkopfs 2 jeweils dem Querschnittsprofil der Ankerschiene 10 angepasst. Im dargestellten Beispiel weist der Ankerkopf eine an sich bekannte sog. Hammerkopfform auf, wobei das Eingriffsteil des Ankerkopfs 2, das innerhalb der Ankerschiene 10 lagert, über einen schmaleren Anbindungssteg 13 mit der breiteren Zuglasche 1 in Verbindung steht.Essential is the spatial shape of the pull tab 1 or 1 ', which ensures that high holding forces can be transmitted.

Der Krümmungsradius r des Bogenstegs 16 beträgt 120 bis 150 mm, insbesondere 130 bis 140 mm.The radius of curvature r of the sheet web 16 is 120 to 150 mm, in particular 130 to 140 mm.

Vorzugsweise liegen die Löcher 3 in der Quermitte des Ankerblechstegs 14 angeordnet und zwar zweckmäßigerweise in einem Abstand von mindestens 60 mm, vorzugsweise in einem Abstand zwischen 60 und 80 mm, insbesondere zwischen 60 und 65 mm.Preferably, the holes 3 are arranged in the transverse center of the anchor plate web 14 and that expediently at a distance of at least 60 mm, preferably at a distance between 60 and 80 mm, in particular between 60 and 65 mm.

Nach einer besonderen Ausführungsform der Erfindung sind auch im Bogenblechsteg 16 Löcher 3' vorgesehen, zweckmäßigerweise im gleichen Abstand voneinander wie die Löcher 3 im Ankerblechsteg 14, wobei vorzugsweise ein Loch 3' im Bogenscheitel angeordnet ist.According to a particular embodiment of the invention 16 holes 3 'are provided in the sheet metal web, expediently at the same distance from each other as the holes 3 in the anchor plate web 14, wherein preferably a hole 3' is arranged in the apex of the bow.

Nach einer weiteren Ausführungsform der Erfindung ist vorgesehen, dass eine Gruppe von z. B. drei Löchern 3 im Bogenblechsteg 16 und eine Gruppe von z. B. drei Löchern 3 im Ankerblechsteg 14 angeordnet ist, wobei der Abstand zwischen den Gruppen z. B. zwischen 90 und 120 mm, insbesondere zwischen 100 und 110 mm liegt. Die Löcher 3, 3' sind zweckmäßigerweise kreisrund und haben vorzugsweise einen Durchmesser von 8 bis 12 mm, insbesondere von 9 bis 11 mm.According to a further embodiment of the invention it is provided that a group of z. B. three holes 3 in the sheet metal web 16 and a group of z. B. three holes 3 is arranged in the anchor plate web 14, wherein the distance between the groups z. B. between 90 and 120 mm, in particular between 100 and 110 mm. The holes 3, 3 'are expediently circular and preferably have a diameter of 8 to 12 mm, in particular from 9 to 11 mm.

Durch diese Anordnung der Löcher und die Verwendung von Hohlnägeln, die in die Löcher passen, wird erreicht, dass diese Kraftübertragungsstellen gleichmäßig belastet werden und keine Spaltung infolge zu dicht benachbarter Nägel auftritt.By this arrangement of the holes and the use of hollow nails, which fit into the holes, it is achieved that these power transmission points are evenly loaded and no cleavage occurs as a result of too closely adjacent nails.

Zwischen dem Ankerkopf 2 und dem ersten Loch 3' im Bogenblechsteg 16 ist zweckmäßigerweise ein Abstand von mindestens 150 mm, insbesondere von 150 bis 200 mm vorgesehen.Between the anchor head 2 and the first hole 3 'in the sheet metal web 16, a distance of at least 150 mm, in particular from 150 to 200 mm is expediently provided.

Der zusammen mit der erfindungsgemäßen Zuglasche 1 zu verwendende Hohlnagel 4 ist in einer bevorzugten Ausführungsform in Fig. 3 dargestellt. Dieser Hohlnagel 4 besteht aus einem eingerollten Blechstreifen aus rostfreiem Stahl, z. B. Edelstahl, und weist einen sich über seine gesamte Länge erstreckenden, etwas offen stehenden Längsschlitz 5 auf. Der Nagelkopf besteht aus einer trichterförmigen Aufweitung des Nagelschafts. Der Durchmesser des Hohlnagels 4 ist gleich groß oder geringfügig größer als der Durchmesser der Löcher 3, 3', so dass der Hohlnagel 4 nach dem Einschlagen spielfrei bzw. passend in dem zugehörigen Loch 3, 3' sitzt, wodurch eine gute Kraftübertragung zwischen jedem Hohlnagel 4 und dem zugehörigen Loch 3, 3' gewährleistet ist.The hollow nail 4 to be used together with the pull tab 1 according to the invention is in a preferred embodiment in FIG Fig. 3 shown. This hollow nail 4 consists of a rolled sheet metal strip made of stainless steel, for. As stainless steel, and has a extending over its entire length, slightly open longitudinal slot 5. The nail head consists of a funnel-shaped widening of the nail shaft. The diameter of the hollow nail 4 is equal to or slightly larger than the diameter of the holes 3, 3 ', so that the hollow nail 4 after driving seated fit or in the associated hole 3, 3', whereby a good power transmission between each hollow nail 4 and the associated hole 3, 3 'is guaranteed.

Um das Einführen des Hohlnagels 4 in ein Loch 3, 3' zu erleichtern, ist das untere Ende des Hohlnagels 4 etwas kleiner als der Lochdurchmesser (nicht dargestellt). Durch den offenen Längsschlitz 5 wird erreicht, dass sich der Hohlnagel beim Einschlagen in das Loch im Durchmesser etwas verkleinern kann und immer passend im Loch 3, 3' sitzt. Die Verwendung von Hohlnägeln 4 mit rundem Querschnitt hat den Vorteil, dass der Nagel in jeder senkrecht zur Nagelachse verlaufenden Kraftrichtung gleichgroße Kräfte übertragen kann. Damit die Korrosionsbeständigkeit der Zuglasche 1 gewährleistet ist, sollte diese z. B. aus rostfreiem Stahlblech, insbesondere aus Edelstahl bestehen. Um an Blechmaterial einzusparen und eine möglichst kostengünstige Herstellung der Zuglasche 1 zu ermöglichen, ist es vorteilhaft, wenn die Zuglasche 1 parallel liegend aus einem Blechband mit einer Breite von z. B. 500 mm ausgestanzt wird. Die erfindungsgemäße Raumform der Zuglasche 1 ermöglicht in überraschender Weise auch, einen aus Fig. 4 erkennbaren Stanzplan zu verwenden, der eine sehr abfallarme Stanzung aus einem Blechband ermöglicht.In order to facilitate the insertion of the hollow nail 4 in a hole 3, 3 ', the lower end of the hollow nail 4 is slightly smaller than the hole diameter (not shown). Through the open longitudinal slot 5 ensures that the hollow nail when driving into the hole in diameter can reduce slightly and always fits in the hole 3, 3 'sits. The use of hollow nails 4 with a round cross-section has the advantage that the nail can transmit equally large forces in any direction perpendicular to the axis of the nail force. Thus, the corrosion resistance of the pull tab 1 is guaranteed, this z. B. stainless steel sheet, in particular made of stainless steel. In order to save on sheet metal and to enable the most cost-effective production of the pull tab 1, it is advantageous if the pull tab 1 lying in parallel from a metal strip with a width of z. B. 500 mm is punched out. The spatial form of the pull tab 1 according to the invention also makes it possible in a surprising manner to make one Fig. 4 recognizable punching plan to use, which allows a very low-waste punching from a sheet metal strip.

Die neue Verankerungsvorrichtung ist wirtschaftlich herstellbar, da für die Zuglasche selbst verhältnismäßig dünnes Blech verwendet werden kann. Desgleichen sind aus Blech bestehende Hohlnägel kostengünstig herstellbar. Der Montageaufwand ist verhältnismäßig gering, da jeweils nur der Ankerkopf in die Ankerschiene eingehängt werden muss und dann einige Hohlnägel z. B. 6, eingeschlagen werden müssen. Die Anordnung der Löcher ist so gewählt, dass die Hohlnägel gleichmäßig belastet werden und auch keine Spaltwirkung infolge zu dicht benachbarter Nägel auftritt. Die Hohlnägel gewährleisten infolge ihres runden, d. h. symmetrischen Querschnitts eine gleichmäßige Kraftübertragung vom Zuglaschenblech auf die Porenbetonplatte und umgekehrt. Eine gleichmäßige Kraftübertragung von der Zuglasche auf die Hohlnägel wird auch dadurch gewährleistet, dass diese passend in den Löchern der zuglasche sitzen.The new anchoring device can be produced economically, since relatively thin sheet metal can be used for the pull tab itself. Likewise, existing hollow metal nails are inexpensive to produce. The assembly effort is relatively low, since only the anchor head must be hung in the anchor rail and then some hollow nails z. B. 6, must be taken. The arrangement of the holes is chosen so that the hollow nails are loaded evenly and also no splitting effect as a result of too closely adjacent nails. The hollow nails ensure due to their round, d. H. Symmetrical cross section, a uniform force transmission from the pull tab plate on the aerated concrete plate and vice versa. A uniform power transmission from the pull tab on the hollow nails is also ensured by the fact that they fit snugly in the holes of zuglasche.

Vor der Montage von Porenbetonplatten vor vertikalen Stützen bzw. Tragelementen einer Bautragkonstruktion werden Ankerschienen 10 mit einem einseitig offenen hinterschnittenen Profil, z. B. C-Profil, in üblicherweise an oder in Begrenzungsflächen 11 der Stützen 12, 12a befestigt. Dies kann je nach der Art der Stütze durch Eingießen, z. B. in Beton, durch Anschweißen an Stahlstützen oder auch durch Anschrauben an Stahl-, Beton- oder Holzkonstruktionen erfolgen. Der Ankerkopf 2 weist eine dem jeweiligen Profil der Ankerschiene 10 angepasste Form, z. B. Hammerkopfform, auf. Nachdem eine Porenbetonplatte vor zwei beabstandete Stützen 12 gesetzt ist, wird eine zuglasche 1 mit dem Ankerkopf 2 in eine vertikale Lage gebracht, so dass der Ankerkopf 2 in den Schlitz der Ankerschiene eingreift. Durch Verdrehen um 90° wird die Zuglasche in eine horizontale Lage gebracht, wobei sich der Ankerkopf in der Ankerschiene 10 verriegelt. Die Ankerplatte wird in horizontaler Lage auf die obere bei Vorhandensein von Federn 18 gegebenenfalls vorher abgeflachte horizontale Stirnseitenoberfläche 9 bzw. Schmalseitenoberfläche der vertikal angeordneten Porenbetonwandplatte aufgelegt, und es werden dann nacheinander Hohlnägel 4 in die sechs Löcher 3, 3' der Zuglasche 1 eingeschlagen. Derselbe Vorgang wird am anderen Ende der Porenbetonplatte vorgenommen, und damit ist die eigentliche Montage beendet.Before the assembly of aerated concrete panels in front of vertical supports or support elements of a building support structure anchor channels 10 with a one-sided open undercut profile, z. B. C-profile, usually attached to or in boundary surfaces 11 of the supports 12, 12 a. This can, depending on the type of support by pouring, z. B. in concrete, by welding to steel columns or by screwing to steel, concrete or wooden structures. The anchor head 2 has a shape adapted to the respective profile of the anchor rail 10 form, for. B. hammerhead shape, on. After an aerated concrete plate is placed in front of two spaced supports 12, a zuglasche 1 is brought to the anchor head 2 in a vertical position, so that the anchor head 2 engages in the slot of the anchor rail. By turning by 90 °, the pull tab is brought into a horizontal position, wherein the anchor head locks in the anchor rail 10. The anchor plate is in a horizontal position on the upper in the presence of springs 18 optionally previously flattened horizontal end surface 9 or narrow side surface of the vertical arranged aerated concrete wall plate placed, and then successively hollow nails 4 in the six holes 3, 3 'of the pull tab 1 are taken. The same process is performed at the other end of the aerated concrete slab, and thus the actual assembly is completed.
