Description
Bewehrungsanker mit Bewehrungshalter für die Schubbewehrung von Stahlbetonplatten oder -balkenReinforcement anchor with reinforcement holder for shear reinforcement of reinforced concrete slabs or beams
Die Erfindung betrifft einen Bewehrungsanker mit Bewehrungshalter für die Schubbewehrung von Stahlbetonplatten oder -balken, wobei der Bewehrungsanker einen sich im Einbauzustand senkrecht zur Platten- oder Balkenebene erstreckenden länglichen Ankerschaft aufweist, der an mindestens einem Ende mit einem scheibenförmigen Ankerkopf versehen ist.The invention relates to a reinforcement anchor with a reinforcement holder for the shear reinforcement of reinforced concrete slabs or beams, wherein the reinforcement anchor has an elongated anchor shaft extending perpendicular to the plate or beam plane in the installed state, which is provided at least at one end with a disk-shaped anchor head.
Derartige Bewehrungsanker dienen dazu, die in Stahlbetonplatten oder -balken auftretenden Schubbeanspruchungen aufzunehmen. Hierzu wirken die über die Stahlbetonplatten oder -balken verteilten, insbesondere aber im Bereich der Einleitung von Stützlasten angeordneten Bewehrungsanker mit einer Biege- und Druckbewehrung der Stahlbetonplatte zusammen. Diese Bewehrungslagen bestehen aus parallel zu einer Platten¬ oder Balkenebene verlaufenden Bewehrungsstäben, mit denen die Bewehrungsanker formschlüssig verbunden werden müssen.Such reinforcement anchors serve to absorb the shear stresses occurring in reinforced concrete slabs or beams. For this purpose, the reinforcement anchors distributed over the reinforced concrete slabs or beams, but particularly arranged in the area of the introduction of supporting loads, interact with a bending and pressure reinforcement of the reinforced concrete slab. These reinforcement layers consist of reinforcement bars running parallel to a slab or beam plane, with which the reinforcement anchors must be connected in a form-fitting manner.
Zu diesem Zweck greifen die scheibenförmigen Ankerköpfe der Bewehrungsanker um die Druckbewehrungslage und um die Biegebewehrungslage der Stahlbetonplatte. Es ist wichtig, daß diese räumliche Zuordnung der Bewehrungsanker und der Bewehrungslagen auch beim Einbringen des Betons erhalten bleiben muß, da anderenfalls keine ausreichende BewehrungsWirkung erzielt wird. Zur Abstützung einer Bewehrungslage in der vorgegebenen Entfernung zu einer anderen ist es bekannt, zwischen den beiden Bewehrungslagen Bewehrungskörbe oder ähnliche Abstandshalter einzusetzen. Dadurch wird die eine Bewehrungslage in einer solchen Entfernung gehalten, daß die Ankerköpfe der Bewehrungsanker über diese Bewehrungsläge hinausragen.For this purpose, the disc-shaped anchor heads of the reinforcement anchors grip around the pressure reinforcement layer and around the bending reinforcement layer of the reinforced concrete slab. It is important that this spatial assignment of the reinforcement anchors and the reinforcement layers must also be maintained when the concrete is being placed, otherwise the reinforcement effect will not be sufficient. To support one reinforcement layer at the specified distance from another, it is known to use reinforcement cages or similar spacers between the two reinforcement layers. As a result, the one reinforcement layer is held at a distance such that the anchor heads of the reinforcement anchors protrude beyond this reinforcement layer.
Um eine ausreichende und angestrebte formschlüssige Verbindung der Ankerköpfe mit den Bewehrungsstäben dieser Bewehrungsläge zu erzielen, ist es darüberhinaus aber erforderlich, daß die Bewehrungsstäbe an der Innenfläche des scheibenförmigen Ankerkopfes anliegen; mit anderen Worten, die scheibenförmigen Ankerköpfe müssen die Bewehrungsstäbe der Bewehrungsläge übergreifen. Sinn dieser formschlüssigen Verbindung ist es, die Sicherung einer möglichst großen statisch nutzbaren Dicke der Stahlbetonplatte zu erzielen.In order to achieve a sufficient and desired positive connection of the anchor heads with the reinforcement bars of this reinforcement layer, it is also necessary that the reinforcement bars rest on the inner surface of the disk-shaped anchor head; in other words, the disc-shaped anchor heads must overlap the reinforcement bars of the reinforcement layer. The purpose of this form-fitting connection is to ensure the greatest possible statically usable thickness of the reinforced concrete slab.
Diese erforderliche formschlüssige Verbindung und räumliche Zuordnung der Bewehrungsanker und der zugehörigen Bewehrungsläge kann bisher nur dadurch sichergestellt werden, daß die Bewehrungsstäbe der einen Bewehrungsläge mit den Bewehrungsankern mittels Rödeldraht verbunden werden, der einen Bewehrungshalter bildet. Die Anbringung solcher Bewehrungshalter aus Rödeldraht ist aber verhältnismäßig umständlich und zeitaufwendig. Da die scheibenförmigen Ankerköpfe üblicherweise rund sind, findet der Rödeldraht am Ankerkopf keinen Halt; es ist vielmehr nur möglich, den Bewehrungsstab mit dem Ankerschaft zu verbinden. Dadurch verbleibt zwischen dem Bewehrungsstab und der Innenfläche des Ankerkopfs ein Spalt, der eine direkte formschlüssige Kraftübertragung in diesem Bereich durch direkte Berührung des BügeIschenkels und der Innenfläche des Ankerkopfes verhindert. Aufgabe der Erfindung ist es daher, einen Bewehrungsanker mit Bewehrungshalter der eingangs genannten Gattung zu schaffen, der in einem einfachen Arbeitsgang eine sichere und formschlüssige Verbindung der Bewehrungsanker mit den Bewehrungsstäben ermöglicht.This required positive connection and spatial assignment of the reinforcement anchors and the associated reinforcement layer can only be ensured so far by connecting the reinforcement bars of the one reinforcement layer to the reinforcement anchors using a wire rod, which forms a reinforcement holder. The attachment of such reinforcement brackets made of tubular wire is relatively cumbersome and time-consuming. Since the disk-shaped anchor heads are usually round, the tie wire cannot be held on the anchor head; it is only possible to connect the reinforcement bar to the anchor shaft. This leaves a gap between the reinforcing bar and the inner surface of the anchor head, which prevents direct positive force transmission in this area by direct contact of the bow leg and the inner surface of the anchor head. The object of the invention is therefore to provide a reinforcement anchor with a reinforcement holder of the type mentioned at the outset, which enables a secure and positive connection of the reinforcement anchors to the reinforcement bars in a simple operation.
Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß der Ankerkopf in seiner Stirnfläche eine Haltebohrung aufweist und daß der Bewehrungshalter ein federnder Drahtbügel ist, der mit einem oberen Bügelschenkel an der Stirnfläche des Ankerkopfes liegt und mit einem Haltevorsprung in die Haltebohrung eingreift und mit einem seitlichen Bügelschenkel hakenförmig einen an der Innenfläche des Ankerkopfes und am Ankerschaft anliegenden Bewehrungsstab umgreift.This object is achieved in that the anchor head has a holding hole in its end face and that the reinforcement holder is a resilient wire bracket which lies with an upper bracket leg on the end face of the anchor head and engages with a retaining projection in the retaining hole and hook-shaped with a lateral bracket leg encompasses a reinforcing bar lying on the inner surface of the anchor head and on the anchor shaft.
Der federnde Drahtbügel, der bei der Herstellung der Bewehrung mit einem einfachen und raschen Bewegungsablauf über den Ankerkopf und den zugeordneten Bewehrungsstab eingerastet wird, drückt den Bewehrungsstab federnd in den zwischen der Innenfläche des Ankerkopfes und dem Ankerschaft gebildeten Winkel. Dort wird der Bewehrungsstab auch während des Betonierens sicher gehalten. In der fertiggestellten Stahlbetonplatte liegt der Ankerkopf mit seiner Innenfläche daher unmittelbar am Bewehrungsstab an, wodurch eine direkte formschlüssige Kraftübertragung sichergestellt ist.The resilient wire bracket, which snaps into place during the manufacture of the reinforcement with a simple and rapid movement of the anchor head and the associated reinforcement bar, resiliently presses the reinforcement bar into the angle formed between the inner surface of the anchor head and the anchor shaft. There the reinforcement bar is held securely even during concreting. In the finished reinforced concrete slab, the anchor head lies with its inner surface directly on the reinforcing bar, which ensures direct positive force transmission.
Vorzugsweise ist die Haltebohrung zentrisch in der Stirnfläche des Ankerkopfes angeordnet. Dadurch wird erreicht, daß der Bewehrungshalter sich nach jeder beliebigen Seite erstrecken kann.The holding bore is preferably arranged centrally in the end face of the anchor head. This ensures that the reinforcement holder can extend to any side.
Da mehrere Bewehrungshalter mit ihren Haltevorsprüngen in dieselbe Haltebohrung eingreifen können, können erforderlichenfalls mehrere Bewehrungshalter an einem Ankerkopf angebracht werden. Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Since several reinforcement holders can engage with their holding projections in the same holding hole, if necessary, several reinforcement holders can be attached to one anchor head. Further advantageous embodiments of the inventive concept are the subject of further subclaims.

Fig. 1 einen Bewehrungsanker für die Schubbewehrung von Stahlbetonplatten mit zwei BewehrungsStäben aus zwei getrennten Bewehrungslagen undFig. 1 is a reinforcement anchor for the shear reinforcement of reinforced concrete slabs with two reinforcement bars from two separate reinforcement layers and
Fig. 2 den bei der Anordnung nach Fig. 1 verwendeten Bewehrungshalter.Fig. 2 shows the reinforcement holder used in the arrangement according to Fig. 1.
Der in Fig. 1 gezeigte Bewehrungsanker 1 weist einen länglichen Ankerschaft 2 auf, der sich im Einbauzustand senkrecht zur Plattenebene der zu bewehrenden (nicht dargestellten) Stahlbetonplatte oder eines Balkens erstreckt. An seinen beiden Enden hat der zylindrische, stabförmige Ankerschaft 2 jeweils einen scheibenförmigen Ankerkopf 3, der vorzugsweise einstückig angestaucht ist. Beim dargestellten Ausführungsbeispiel ist der Ankerkopf 3 jeweils kreisförmig.The reinforcement anchor 1 shown in FIG. 1 has an elongated anchor shaft 2 which, in the installed state, extends perpendicular to the plate plane of the reinforced concrete plate (not shown) or a beam to be reinforced. At both ends, the cylindrical, rod-shaped anchor shaft 2 has a disk-shaped anchor head 3, which is preferably upset in one piece. In the illustrated embodiment, the anchor head 3 is circular.
Ein parallel zur Plattenebene verlaufender Bewehrungsstab 4 einer ersten Bewehrungsläge der Stahlbetonplatte liegt an der Innenseite des unteren Ankerkopfes 3 und am Ankerschaft 2 an. Ein Bewehrungsstab 5 einer zweiten Bewehrungslage der Stahlbetonplatte liegt an der Innenseite 3a des oberen Ankerkopfes 3 und am Ankerschaft 2 an. Der Bewehrungsstab 5 wird in dieser Lage durch einen aus einem federnden Drahtbügel bestehenden Bewehrungshalter 6 gehalten. Der eine, obere Bügelschenkel 7 des Bewehrungshalters 6 liegt an der oberen Stirnfläche 3b des Ankerkopfes 3 an und verläuft dort angenähert radial. Am oberen Bügelschenkel 7 ist eine im wesentlichen U-förmige Lasche 8 ausgebildet, die als Haltevorsprung in eine Haltebohrung 9 in der Stirnfläche 3b des Ankerkopfes 3 greift. Die Haltebohrung 9 ist zentrisch in der Stirnfläche 3b angeordnet. An die U-förmige Lasche 8 schließt sich ein an der Stirnfläche 3b des Ankerkopfes 3 anliegender Endabschnitt 10 des Bügelschenkels 7 an.A reinforcement bar 4 of a first reinforcement layer of the reinforced concrete slab running parallel to the plane of the plate rests on the inside of the lower anchor head 3 and on the anchor shaft 2. A reinforcement bar 5 of a second reinforcement layer of the reinforced concrete slab lies against the inside 3a of the upper anchor head 3 and against the anchor shaft 2. The reinforcement bar 5 is held in this position by a reinforcement holder 6 consisting of a resilient wire bracket. The one, upper stirrup leg 7 of the reinforcement holder 6 lies on the upper end face 3b of the anchor head 3 and runs approximately radially there. A substantially U-shaped tab 8 is formed on the upper bracket leg 7 and engages as a holding projection in a holding hole 9 in the end face 3 b of the anchor head 3. The holding hole 9 is arranged centrally in the end face 3b. The U-shaped tab 8 is adjoined by an end section 10 of the stirrup leg 7 which bears against the end face 3b of the anchor head 3.
Am oberen Rand des Ankerkopfes 3 ist der den Bewehrungshalter 6 bildende Drahtbügel nach unten umgebogen und bildet einen seitlichen Bügelschenkel 11, der den Bewehrungsstab 5 umgreift und in seiner Lage hält.At the upper edge of the anchor head 3, the wire bracket forming the reinforcement holder 6 is bent downward and forms a lateral bracket leg 11 which engages around the reinforcement bar 5 and holds it in position.
Der seitliche Bügelschenkel 11 weist einen kreisbogenförmigen Endabschnitt 12 auf, dessen Radius angenähert gleich dem Radius des umgriffenen Bewehrungsstabes 5 ist. Dieser kreisbogenförmige Endabschnitt umgreift den Bewehrungsstab 5 nur teilweise; vorzugsweise erstreckt sich der Endabschnitt über einen Kreisbogen von etwa 130° bis etwa 160°.The side bracket leg 11 has an arcuate end section 12, the radius of which is approximately equal to the radius of the encompassing reinforcing bar 5. This circular arc-shaped end section only partially surrounds the reinforcing bar 5; the end section preferably extends over a circular arc from approximately 130 ° to approximately 160 °.
Der Bewehrungsstab 4 der anderen Bewehrungsläge kann in entsprechender Weise mit einem Bewehrungshalter 6 befestigt werden, wie er einzeln in Fig. 2 dargestellt ist. The reinforcement bar 4 of the other reinforcement layer can be fastened in a corresponding manner with a reinforcement holder 6, as is shown individually in FIG. 2.
