Description
Halteanker zum Verbinden zweier durch eine Dämmschicht getrennter Betonplatten sowie aus wenigstens diesen Teilen gebildete Holding anchor for connecting two separated by an insulating layer concrete slabs and at least these parts formed
B etonplatteneinheit B flat panel unit
Die Erfindung betrifft einen Halteanker zum Verbinden zweier durch eine Dämmschicht getrennter, mit Bewehrungsstäben durchsetzter Betonplatten, die zusammen eine Betonplatteneinheit bilden, wobei der Halteanker aus einem Flachstahl besteht und U-förmig so gestaltet ist, so dass zwei durch einen Verbindungsabschnitt verbundene Schenkel gebildet sind, die an ihren freien Enden eine Spitze aufweisen und wobei an jedem Schenkel mindestens ein zur Aufnahme eines Bewehrungsstabes geeigneter Durchbruch vorgesehen ist. The invention relates to a retaining anchor for connecting two concrete slabs separated by an insulating layer, which together form a concrete slab unit, wherein the retaining anchor consists of a flat steel and is U-shaped so that two legs connected by a connecting section are formed, which have a tip at their free ends and at least one suitable for receiving a reinforcing bar breakthrough is provided on each leg.
Die Erfindung betrifft ferner eine Betonplatteneinheit, die aus den eben genannten Bauteilen gebildet ist. The invention further relates to a concrete slab unit, which is formed from the above-mentioned components.
Halteanker werden zu Herstellung von Betonplatteneinheiten verwendet. Letztere wiederum finden Anwendung im Baubereich. Retaining anchors are used to make concrete slab units. The latter in turn are used in the construction sector.
Die DE 10 2005 017 964 AI beschreibt einen Halteanker der eingangs genannten Art sowie dessen Verwendung. Solche Halteanker dienen dazu, zwei durch eine Dämmschicht getrennte Betonplatten zu verbinden. Die Verbindung erfolgt bei der Herstellung der Betonplatteneinheiten, also zu einem Zeitpunkt, in dem die Betonplatten gegossen werden. In der Praxis sind derartige Betonplatteneinheiten verschiedensten Kräften ausgesetzt. Druck-, Zug-, Biege- und Scherkräfte wirken auf die Betonplatten ein und es gilt, diese Kräfte aufzufangen, zumal die zwischen den Betonplatten angeordnete Dämmschicht nur wenig zur Beherrschung dieser Kräfte beitragen kann. Neben den in den Betonplatten verwendeten Bewehrungsstäben haben vor allem die Halteanker wichtige Funktionen zu erfüllen, die sich nicht nur darin erschöpfen, beide Betonplatten zusammen zu halten. DE 10 2005 017 964 AI describes a retaining anchor of the type mentioned and its use. Such retaining anchors serve to connect two concrete slabs separated by an insulating layer. The connection takes place in the production of concrete slab units, ie at a time when the concrete slabs are poured. In practice, such concrete slab units are subjected to a wide variety of forces. Compressive, tensile, bending and shear forces act on the concrete slabs and it is important to absorb these forces, especially since the insulating layer arranged between the concrete slabs can only contribute little to the control of these forces. In addition to the reinforcing bars used in the concrete slabs, especially the holding anchors have important functions to fulfill, which are not only exhaustive in holding both concrete slabs together.
Die Herstellung von Betonplatteneinheiten unter Verwendung von Halteankern erfolgt mit Hilfe entsprechender Vorrichtungen. Tätigkeiten von Hand sind allerdings, trotz maschineller Unterstützung, dennoch erforderlich. Ein Teil dieser manuellen Tätigkeit besteht im Anordnen und Setzen der Halteanker innerhalb der genannten Vorrichtungen. Bei der Herstellung der Betonplatteneinheiten ist es wünschenswert, die Halteanker exakt senkrecht zu setzen. Dies gelingt jedoch nicht immer. Manuelle Ungenauigkeiten sowie das Eingießen des Betonmörtels in die Vorrichtungen können bewirken, dass die Halteanker durchaus leicht schrägt angeordnet sind und in dieser Lage verbleibend letztendlich einbetoniert werden. Manche Halteanker durchdringen somit die zwischen den beiden Betonplatten angeordnete Dämmschicht in etwas schräger Lage. Während bei auftretenden, zwischen den beiden Betonplatten wirkenden Zugkräften auch leicht schräg einbetonierte Halteanker zuverlässig wirken, kann es beim Auftreten von Druckkräften oder Scherkräften Probleme geben. Ein schädliches gegenläufiges oder auch parallelogrammartiges Bewegen der beiden Betonplatten kann sich durchaus dann einstellen, wenn die Materialdicke der aus Flachstahl gebildeten Halteanker zu gering ist. Umgekehrt will man wiederum aus Kostengründen die Materialdicke der Halteanker so gering als möglich halten. The production of concrete slab units using retaining anchors is carried out by means of appropriate devices. Activities by hand however, despite machine assistance, they are still required. Part of this manual activity is the placing and setting of the retaining anchors within said devices. In the manufacture of the concrete slab units, it is desirable to set the holding anchor exactly vertical. However, this does not always succeed. Manual inaccuracies as well as the pouring of the concrete mortar into the devices can cause the retaining anchors to be arranged slightly obliquely and ultimately be embedded in this layer. Some retaining anchors penetrate thus arranged between the two concrete slabs insulation layer in a slightly oblique position. While occurring when acting between the two concrete slabs tensile forces also slightly obliquely cast anchor anchor act reliably, there may be problems in the presence of compressive forces or shear forces. A damaging counter-rotating or parallelogram-like movement of the two concrete slabs can quite well adjust if the material thickness of the retaining anchor formed from flat steel is too low. Conversely, one wants to keep the material thickness of the holding anchor as low as possible again for cost reasons.
Ausgehend von diesem Sachverhalt besteht die Aufgabe der Erfindung darin, einen Halteanker der hier vorliegenden Art so weiter zu entwickeln, dass die Kosten für dessen Herstellung niedrig bleiben und dass dennoch eine größere Sicherheit derart erreicht wird, dass die eben beschriebenen, insbesondere bei Druck-, Biege- und Scherkräften auftretenden Probleme vermieden werden. Based on this fact, the object of the invention is to develop a retaining anchor of the present type so that the cost of its production remain low and yet greater security is achieved such that the just described, especially in printing, Bending and shearing forces occurring problems can be avoided.
Ebenso gilt es, eine Betonplatteneinheit der hier vorliegenden Art so zu gestalten, dass sich die vorab beschriebenen Probleme nicht einstellen können. Likewise, it is necessary to design a concrete slab unit of the present type such that the problems described above can not be established.
Die Lösung der Aufgabe bezüglich des Halteankers ist im kennzeichnenden Teil des Anspruches 1 beschrieben. Die Lösung der Aufgabe, bezogen auf die Betonplatteneinheit, findet sich im kennzeichnenden Teil des Anspruches 8. The solution of the problem with respect to the retaining anchor is described in the characterizing part of claim 1. The solution of the problem, based on the concrete slab unit, can be found in the characterizing part of claim 8.
Der Vorteil der für den Halteanker vorgeschlagenen Lösung besteht darin, dass durch das Einbringen von wenigstens einer Erhöhung pro Schenkel die Biegefestigkeit der Schenkel entscheidend erhöht wird. Bei auftretenden Druckkräften, welche versuchen, die beiden Betonplatten gegeneinander zu drücken, wird die Gefahr einer im Bereich der Dämmschicht zu befürchtenden Knickung der beiden Schenkel erheblich reduziert. The advantage of the solution proposed for the retaining anchor is that the bending strength of the legs is decisively increased by the introduction of at least one elevation per leg. When pressure forces occur, which try to press the two concrete slabs against each other, the risk of fear in the insulating layer to be feared buckling of the two legs is significantly reduced.
Bei zwischen den beiden Betonplatten auftretenden Scherkräften wiederum wird die Gefahr einer im Bereich der Dämmschicht stattfindenden Biegung der Schenkel der Halteanker ebenfalls entscheidend vermindert. When occurring between the two concrete slabs shear forces in turn, the risk of taking place in the region of the insulating layer bending the legs of the retaining anchor is also significantly reduced.
Die Biegefestigkeit des Halteankers lässt sich in zweckmäßiger Weise noch steigern, wenn die Erhöhungen von den Schenkeln aus in den Verbindungs- abschnitt weiter geführt sind. Dadurch ist ein sicheres und lagegenaues Einschlagen des Halteankers in eine Dämmschicht garantiert. The flexural strength of the retaining anchor can be increased in a useful manner, if the elevations from the thighs continue in the connection section. As a result, a safe and accurate impact of the retaining anchor is guaranteed in an insulating layer.
Die vorgeschlagene Lösung erlaubt es, die bisher in der Praxis gewählte Materialdicke bei den Halteankern beizubehalten und dennoch eine größere Stabilität zu erzielen. The proposed solution makes it possible to maintain the previously chosen in practice material thickness in the retaining anchors and still achieve greater stability.
Bezüglich der Betonplatteneinheit besteht der entscheidende Vorteil darin, dass die bei den Schenkeln der Halteanker berücksichtigte Erhöhung in beide Betonplatten weitergeführt ist. Diese Erhöhungen befinden sich also nicht nur im Bereich der Dämmschicht, sondern sie werden mit ihren Endabschnitten in die Betonplatten weiter geführt und in die beiden Betonplatten mit eingegossen. Dadurch lassen sich neben den Zugkräften vor allen Dingen die auftretenden Druck-, Biege- und Scherkräfte viel besser beherrschen als bisher möglich. With regard to the concrete slab unit, the decisive advantage is that the increase taken into account in the legs of the retaining anchors is continued in both concrete slabs. These elevations are thus not only in the area of the insulating layer, but they are continued with their end sections in the concrete slabs and poured into the two concrete slabs with. As a result, in addition to the tensile forces, above all, the pressure, bending and shearing forces that occur can be controlled much better than previously possible.

In die nachfolgende Beschreibung lassen sich alle technischen Merkmale übertragen, die in der DE 10 2005 017 964 AI beschrieben sind. Diese Merkmale, zu denen z. B. die Spitzen der Schenkel nebst ihrer Durchstechfunktion oder die Durchbrüche zur Aufnahme von Bewehrungsstäben gehö- ren, werden deshalb hier nicht erneut beschrieben. Alle nachfolgenden Angaben beziehen sich ausschließlich auf die Lösungen der beiden gestellten Aufgaben. In the following description, all technical features can be transferred, which are described in DE 10 2005 017 964 AI. These features, which z. As the tips of the legs together with their piercing function or the openings for receiving reinforcing bars gehö- ren, therefore, will not be described again here. All subsequent information refers exclusively to the solutions of the two tasks.
Der in den Figuren 1 und 2 dargestellte Halteanker 1 besteht aus Flachstahl oder aus Flachmaterial. In Vorderansicht betrachtet ist der Halteanker 1 U- förmig gestaltet. Seine beiden Schenkel 3 sind durch einen Verbindungsabschnitt 2 miteinander verbunden. Der Verbindungsabschnitt 2 kann anstelle eines horizontal verlaufenden Zwischenabschnittes auch halbkreisförmig oder dachförmig ausgebildet sein. Es sind am Halteanker 1 oben und unten Durchbrüche 13 zur wahlweisen Aufnahme von Bewehrungsstäben 22 eingezeichnet, siehe Fig. 5. Beide Schenkel 3 weisen je eine nach außen gerichtete (in der Zeichnung nach rechts und nach links strebende) Erhöhung 14 auf. Die Erhöhungen 14 befinden sich an je einer Schenkelaußenfläche 4. The retaining anchor 1 shown in Figures 1 and 2 consists of flat steel or flat material. Seen in front view, the retaining anchor 1 is U-shaped. His two legs 3 are connected by a connecting portion 2 with each other. The connecting section 2 may also be semicircular or roof-shaped instead of a horizontally extending intermediate section. There are on the anchor anchor 1 at the top and bottom openings 13 for selectively receiving reinforcing bars 22 shown, see Fig. 5. Both legs 3 each have an outwardly directed (in the drawing to the right and to the left aspiring) increase 14. The elevations 14 are located on each leg outer surface. 4
In Seitenansicht gemäß Fig. 2 dargestellt erkennt man einen der beiden Schenkel 3, die nach unten in einer Spitze 17 enden. Die Funktion beider Spitzen 17 ist bekannt. Die Spitzen 17 sind pfeilförmig gestaltet. Mittig ist an beiden Schenkeln 3 die Erhöhung 14 angeordnet, die bis in die Spitze reichen kann. Die Erhöhung 14 ragt im Beispiel aus der Bildebene heraus. Der Querschnitt der Erhöhung 14 nebst Querschnitt des dargestellten Schenkels 3 ist anhand der angefügten Detailskizze ersichtlich. Die Erhöhung 14 ist als eine in den Schenkel 3 eingeprägte Sicke 15 gestaltet. Beide Schenkel 3 weisen die Sicke 15 auf. Es kann pro Schenkel 3 mehr als eine, die Form einer Sicke 15 aufweisende Erhöhung 14 vorgesehen sein. 2 shows one of the two legs 3, which end in a tip 17 down. The function of both tips 17 is known. The tips 17 are designed arrow-shaped. In the middle of the two legs 3, the increase 14 is arranged, which may extend to the top. The increase 14 protrudes in the example out of the picture plane. The cross section of the elevation 14 together with the cross section of the illustrated leg 3 can be seen on the attached detailed sketch. The increase 14 is designed as a embossed into the leg 3 bead 15. Both Leg 3 have the bead 15. It can be provided per leg 3 more than one, the shape of a bead 15 having 14 increase.
Der in den Figuren 3 und 4 dargestellte Halteanker 1 besteht, wie bereits aus den Figuren 1 und 2 ersichtlich, ebenfalls aus Flachstahl oder Flachmaterial, z. B. aus dickerem Blech. Der in Vorderansicht gezeichnete Halteanker 1 ist ebenfalls U-förmig gestaltet. Er weist zwei Schenkel 3 auf, die durch den Verbindungsabschnitt 2 verbunden sind. Es sind wieder die bereits erwähnten Durchbrüche 13 vorgesehen. An den Schenkelaußenflächen 4 sind Er- höhungen 14 angeformt. The holding anchor 1 shown in Figures 3 and 4 consists, as already apparent from Figures 1 and 2, also made of flat steel or sheet, for. B. from thicker sheet. The drawn in front view retaining anchor 1 is also designed U-shaped. It has two legs 3, which are connected by the connecting portion 2. There are again the aforementioned breakthroughs 13 are provided. At the leg outer surfaces 4 elevations 14 are formed.
In Seitenansicht betrachtet erkennt man wieder einen der beiden Schenkel 3 sowie zwei Erhöhungen 14, die aus der Bildebene heraus ragen. Die freien Enden 6 der Schenkel 3 enden, wie schon vorab gezeigt, wieder in einer Spitze 17. Die beiden Erhöhungen 14 pro Schenkel 3 sind an je einem Rand 7 der Schenkel 3 angeformt, so dass im Bereich der beiden Erhöhungen 14, zusammen mit dem Rücken 8 eines jeden Schenkels, je ein U- förmiger Querschnitt gebildet ist, siehe angefügte Detailansicht. Die beiden zur Spitze 17 gerichteten Endbereiche 16 der Erhöhungen 14 pro Schenkel 3 sind zur Spitze 17 hin bevorzugt schräg zum Rücken 8 zulaufend ausgebildet. Diese Art der Gestaltung ist empfehlenswert, um bei der Herstellung einer Betonplatteneinheit 18 das bekannte Durchstechen der Dämmschicht 21 zu erleichtern, siehe Fig. 5. Seen in side view, one recognizes again one of the two legs 3 and two elevations 14, which protrude out of the image plane. The free ends 6 of the legs 3 ends, as already shown, again in a tip 17. The two elevations 14 per leg 3 are formed on each edge 7 of the legs 3, so that in the region of the two elevations 14, together with the Back 8 of each leg, a U-shaped cross section is formed, see attached detail view. The two end portions 16, directed towards the tip 17, of the elevations 14 per leg 3 are preferably tapered towards the tip 8 towards the tip 17. This type of design is recommended in order to facilitate the known piercing of the insulating layer 21 in the manufacture of a concrete slab unit 18, see FIG. 5.
Es ist zweckmäßig, die Breite der Spitze 17, siehe Fig. 4, geringfügig größer zu wählen als die übrige Breite der Schenkel 3. Die daraus sich ergebende Breitendifferenz ist in der Zeichnung durch die beiden Maße a verdeutlicht. Beim Durchstechen der Dämmschicht 21 macht die breitere Spitze 17 den Weg frei für den beim Durchstechvorgang nachfolgenden Rücken 8 des Halteankers 1. Beim Durchstechen der Dämmschicht 21 nutzt der Rücken 8 den bereits durch die Spitze 17 hergestellten Freiraum. Den Weg frei ste- chen müssen jetzt nur noch die beiden Erhöhungen 14 der Schenkel 3. Der nach unten gerichtete schräge Verlauf der Erhöhungen 14 erleichtert dieses zusätzliche Durchstechen des Halteankers 1. Auch beim Ausführungsbeispiel gemäß den Figuren 1 und 2 kann die Spitzen breiter sein als die übrige Breite der Schenkel 3. It is expedient to choose the width of the tip 17, see Fig. 4, slightly larger than the remaining width of the legs 3. The resulting difference in width is illustrated in the drawing by the two dimensions a. When piercing the insulating layer 21, the wider tip 17 clears the way for the subsequent piercing process back 8 of the retaining anchor 1. When piercing the insulating layer 21 uses the back 8 already produced by the top 17 space. Now only the two elevations 14 of the legs 3 have to clear the way. The downward sloping course of the elevations 14 facilitates this additional puncturing of the retaining anchor 1. Also in the embodiment according to FIGS. 1 and 2, the tips can be wider than the remaining width of the legs 3.
Fig. 5 zeigt in einer Schnittdarstellung einen Teil einer Betonplatteneinheit 18. Der dargestellte Halteanker 1 beinhaltet vergleichsweise beide Lösungen, die in den Figuren 1 bis 4 beschrieben sind. Die Zeichnung zeigt einen Teil einer ersten Betonplatte 19 und einen Teil einer zweiten Betonplatte 20, wobei zwischen beiden Betonplatten 19 und 20 in bekannter Weise eine Dämmschicht 21, beispielsweise aus dem Material„Polystyrol" bestehend, angeordnet ist. Die Zeichnung zeigt den Halteanker 1, bei dem der links dargestellte Schenkel 3 die in den Figuren 1 und 2 beschriebene Lösung zeigt, während der in der Zeichnung rechts dargestellte Schenkel 3 die in den Figuren 3 und 4 vorgeschlagene Lösung offenbart. Bei einer gebrauchsfertigen Betonplatteneinheit 18 beansprucht der mindestens eine Halteanker 1 beide Betonplatten 19, 20 sowie die Dämmschicht 21. Der obere Bereich 12 des Halteankers 1, in dem der Verbindungsabschnitt 2 angeordnet ist, befindet sich zusammen mit einem oberen Bereich 9 der beiden Schenkel 3 in der im Beispiel oben liegenden zweiten Betonplatte 20. In der Dämmschicht 21 ist der Zwischenabschnitt 10 der beiden Schenkel 3 mit einem Teil der Erhöhungen 14 angeordnet. Der untere Bereich 11 der beiden Schenkel 3, der auch die Spitzen 17 der Schenkel 3 aufweist, befindet sich in der im Beispiel unten liegenden ersten Betonplatte 19. Erfindungswesentlich ist nun, dass sich die Erhöhungen 14 der beiden Schenkel 3 in der zweiten Betonplatte 20, in der Dämmschicht 21 und in der ersten Betonplatte 19 befinden. Jede Erhöhung 14 erstreckt sich somit über die Dicke der Dämmschicht 21 hinaus und endet in den beiden Betonplatten 19 und 20. Eine Arretierung der Erhöhungen 14 erfolgt somit in den beiden Betonplatten 19 und 20. Anhand der Zeichnung ergibt sich schlüssig, dass die Erhöhungen 14 im Bereich der Dämmschicht 21 somit entscheidend dazu beitragen, hö- here Druck-, Biege- und Scherkräfte schadlos aufzunehmen, ohne dass die Materialdicke des Halteankers 1 zwingend erhöht werden muß. Durch die Erhöhungen 14 erhöht sich somit das auf die Schenkel 3 bezogene Widerstandsmoment auf einfache Weise. Jede Betonplatteneinheit 18 weist we- nigstens einen Halteanker 1 auf. Jede Betonplatte 19, 20 ist gewöhnlich mit Bewehrungsstäben 22 durchsetzt, die üblicherweise kreuzweise angeordnet sind. Wie bereits erwähnt, lassen die in den Halteankern 1 vorgesehenen Durchbrüche 13 ein Durchführen von Bewehrungsstäben 22 durch die Hal- teanker 1 hindurch zu. Es bleibt dem jeweiligen Anwendungsfall überlassen, ob und in welcher Anzahl Bewehrungsstäbe 22 durch die Halteanker 1 hindurchzuführen sind. Die Betonplatteneinheit 18 kann noch weitere, für die hier vorliegende Erfindung unwesentliche Teile aufweisen. Bei Dämmschichten 21 mit relativ großer Härte oder Steifigkeit kann das beschriebene Durchstechen der Halteanker 1 dazu führen, dass die Schenkel 3 bei etwas ungenauem Aufsetzen auf eine Dämmschicht 21 unkontrolliert zur Seite ausweichen und die Halteanker 1 verbogen werden. Dieses Ausweichen oder Verbiegen lässt sich verhindern, indem man jede von einem Schenkel 3 ausgehende Erhöhung 14 zumindest ein Stück weit in den Verbindungsabschnitt 2 weiter führt und im Verbindungsabschnitt 2 enden lässt. Jede Erhöhung 14 besitzt dann, bezogen auf Fig. 1 und 2, oder auf Fig. 3 und 4, eine rechtwinklige Form. Es ist auch möglich, anstelle von zwei Erhöhungen 14 nur noch eine einzige Erhöhung 14 vorzusehen, die von einem der beiden Schenkel 3 ausgehend, und den Verbindungsabschnitt 2 komplett beanspruchend, zum anderen, also zweiten Schenkel 3 geführt ist. Diese einzige Erhöhung 14 weist dann einen U-förmigen Umriss auf, vgl. Fig. 1 und Fig. 3. Es ist bei allen eben beschriebenen Ausführungsbeispielen möglich, auf die nahe des Verbindungsabschnittes 2 gelegenen Durchbrüche 13 zu verzichten, falls dies die Anzahl der erforderlichen Bewehrungsstäbe 22 zulässt. Auch können die eben genannten Durchbrüche 13 durch die wenigstens eine Erhöhung 14 hindurchgeführt sein. Fig. 5 shows a sectional view of a part of a concrete slab unit 18. The holding anchor 1 shown includes comparatively both solutions, which are described in Figures 1 to 4. The drawing shows a part of a first concrete slab 19 and a part of a second concrete slab 20, wherein an insulating layer 21, for example of the material "polystyrene", is arranged in known manner between both concrete slabs 19 and 20. The drawing shows the slack anchor 1, in which the leg 3 shown on the left shows the solution described in Figures 1 and 2, while the leg 3 shown on the right in the drawing reveals the solution proposed in Figures 3 and 4. In a ready-to-use concrete plate unit 18, the at least one retaining anchor 1 claims both Concrete plates 19, 20 and the insulating layer 21. The upper portion 12 of the retaining anchor 1, in which the connecting portion 2 is arranged, is located together with an upper portion 9 of the two legs 3 in the example lying above the second concrete slab 20. In the insulating layer 21 is the intermediate portion 10 of the two legs 3 with a part of the elevations 14 ang The lower area 11 of the two legs 3, which also has the tips 17 of the legs 3, is located in the first concrete slab 19 lying below in the example. It is now essential to the invention that the elevations 14 of the two legs 3 are in the second concrete slab 20, in the insulating layer 21 and in the first concrete slab 19. Each increase 14 thus extends beyond the thickness of the insulating layer 21 and ends in the two concrete slabs 19 and 20. A locking of the elevations 14 thus takes place in the two concrete slabs 19 and 20. Referring to the drawing, it is conclusive that the elevations 14 in Area of the insulating layer 21 thus contribute significantly to absorb higher pressure, bending and shear forces without damage, without the material thickness of the retaining anchor 1 must be increased mandatory. As a result of the elevations 14, the resistance moment, which relates to the legs 3, increases in a simple manner. Each concrete slab unit 18 has at least one retaining anchor 1 on. Each concrete slab 19, 20 is usually interspersed with reinforcing bars 22, which are usually arranged crosswise. As already mentioned, the openings 13 provided in the retaining anchors 1 allow the reinforcing rods 22 to be passed through the retaining anchors 1. It is left to the particular application, whether and in what number reinforcing bars 22 are passed through the retaining anchor 1. The concrete slab unit 18 may have other, for the present invention insubstantial parts. In insulating layers 21 with relatively high hardness or stiffness described piercing of the retaining anchor 1 can cause the leg 3 dodge in an inaccurate touch on an insulating layer 21 uncontrolled to the side and the retaining anchor 1 are bent. This deflection or bending can be prevented by passing each of a leg 3 outgoing increase 14 at least a little further into the connecting portion 2 and ends in the connecting portion 2. Each elevation 14 then has a rectangular shape with reference to FIGS. 1 and 2, or to FIGS. 3 and 4. It is also possible to provide instead of two elevations 14 only a single increase 14, starting from one of the two legs 3, and the connecting portion 2 completely claimant, to the other, ie second leg 3 is guided. This single elevation 14 then has a U-shaped outline, cf. Fig. 1 and Fig. 3. It is possible in all the embodiments just described to dispense with the located near the connecting portion 2 openings 13, if this allows the number of required reinforcing bars 22. Also, the above-mentioned openings 13 may be passed through the at least one increase 14.
Die wenigstens eine Erhöhung 14 pro Schenkel 3 kann anstelle an der Schenkelaußenfläche 4 eines jeden Schenkels 3, wie vorab beschrieben, auch durchaus an der Schenkelinnenfläche 5 eines jeden Schenkels 3 angeordnet sein. Gleiches gilt auch, wenn sich die wenigstens eine Erhöhung zumindest teilweise im Verbindungsabschnitt 2 befindet. Die wenigstens eine Erhöhung 14 ist dann entweder an der Außenseite oder an der Innensei- te des Verbindungsabschnittes 2 angeordnet. Während bei den in Fig. 1 bis Fig. 4 beschriebenen Ausfuhrungsbeispielen die Erhöhungen 14 an den Schenkeln 3 spiegelbildlich voneinander weggerichtet sind, sind an den Schenkelinnenflächen befindliche Erhöhungen 14 spiegelbildlich zueinan- der gerichtet. The at least one elevation 14 per leg 3 can also be arranged on the leg inner surface 5 of each leg 3 instead of on the leg outer surface 4 of each leg 3, as described above. The same applies if the at least one increase is at least partially in the connecting section 2. The at least one elevation 14 is then either on the outside or on the inside. te of the connecting portion 2 is arranged. While in the exemplary embodiments described in FIGS. 1 to 4, the elevations 14 on the legs 3 are directed mirror-inverted from one another, elevations 14 located on the leg inner surfaces are directed mirror-inverted toward one another.
Alle bis hierher beschriebenen technischen Merkmale lassen sich im Sinne einer zweckmäßigen Ausgestaltung der hier vorliegenden Erfindung untereinander variieren. All technical features described so far can be varied among each other in terms of an expedient embodiment of the present invention.
