Abstract
Die Erfindung betrifft einen Spreizanker (1) aus Metall zur Befestigung eines Bauteils (2) an einem Untergrund (3). Der Spreizanker (1) weist ein Ankergrundteil (4) mit Befestigungsmitteln (5) und mehreren im Durchmesser reduzierten, sich konisch in Einbringrichtung des Spreizankers (1) erweiternden Spreizabschnitten (6) auf, auf die jeweils eine Spreizhülse (8) axial verschiebbar aufgesetzt ist. Um einen derartigen Spreizanker zu schaffen, der bei gleicher Leistungsfähigkeit geringere Herstellkosten aufweist, schlägt die Erfindung vor, dass die Spreizhülsen (8) durch einen Steg (9) zu einem einstückigen Spreizhülsenverband (10) verbunden sind und die Spreizabschnitte (6) mit den Stegen korrespondierende Ausnehmungen (15) aufweisen.The invention relates to an expansion anchor (1) made of metal for fastening a component (2) to a substrate (3). The expansion anchor (1) has an anchor base (4) with fastening means (5) and a plurality of reduced diameter, conically in the insertion direction of the expansion anchor (1) expanding expansion sections (6), on each of which an expansion sleeve (8) is mounted axially displaceable , In order to provide such an expansion anchor, which has lower production costs with the same performance, the invention proposes that the expansion sleeves (8) are connected by a web (9) to a one-piece expansion sleeve dressing (10) and the spreading sections (6) with the webs have corresponding recesses (15).
Description
Die Erfindung betrifft einen Spreizanker aus Metall mit den Merkmalen des Oberbegriffs des Anspruchs 1.The The invention relates to a metal expansion anchor with the features of the preamble of claim 1.

Der Erfindung liegt daher die Aufgabe zu Grunde, einen Spreizanker der eingangs genannten Art zu schaffen, der bei gleicher Leistungsfähigkeit geringere Herstellkosten aufweist.Of the The invention is therefore based on the object, an expansion anchor of to create the aforementioned type, the lower the same performance Has manufacturing costs.
Diese Aufgabe wird erfindungsgemäß durch den Spreizanker mit den Merkmalen des Anspruchs 1 gelöst. Bei dem erfindungsgemäßen Spreizanker sind die Spreizhülsen durch einen Steg zu einem einstückigen Spreizhülsenverband verbunden. Die Spreizabschnitte weisen mit den Stegen korrespondierende Ausnehmungen auf.This The object is achieved by the Expansible anchor solved with the features of claim 1. at the expansion anchor according to the invention are the expansion sleeves through a bridge to a one-piece Spreizhülsenverband connected. The spreading sections have corresponding to the webs Recesses on.
Hierdurch können sämtliche Spreizhülsen eines Spreizankers gemeinsam als ein Teil hergestellt und montiert werden, was die Herstellung erheblich günstiger macht. Vorzugsweise wird dieser Spreizhülsenverband als ein Stanzbiegeteil ausgeführt. Um den Spreizhülsen dennoch die Möglichkeit zu geben, unabhängig voneinander zu verspreizen, sieht eine bevorzugte Ausführungsform der Erfindung vor, dass jeder Steg eine Schwächung aufweist. An dieser Schwächung kann der Steg gelängt oder verkürzt werden. Dies ist wichtig, damit die Spreizhülsen beispielsweise bei einer unregelmäßigen Bohrlochwandung, bei Versagen eines Spreizabschnitts durch einen dynamischen Riss im Untergrund oder dgl. individuell verspreizen können und somit die Traglast durch die anderen Spreizabschnitte übernommen wird.hereby can all expansion sleeves an expansion anchor made and assembled together as a part which makes the production considerably cheaper. Preferably becomes this expansion sleeve bandage executed as a stamped and bent part. To the expansion sleeves nevertheless the possibility to give, independently to brace each other, sees a preferred embodiment the invention that each web has a weakening. At this weakening can the bridge lengthened or shortened. This is important so that the expansion sleeves, for example, at a irregular borehole wall, in case of failure of a spreading section by a dynamic crack in the underground or the like can individually spreader and Thus, the load is taken over by the other spreading sections.
Ein optimiertes Tragverhalten des Spreizankers wird erreicht, wenn die maximalen Spreizwege der einzelnen Spreizhülsen von Spreizhülse zu Spreizhülse in Einbringrichtung des Spreizankers kleiner werden. Hierdurch wird erreicht, dass beim Setzen des Spreizankers die dem Bohrlochgrund nächste Spreizhülse am meisten verspreizt wird, während die anderen entgegen der Einbringrichtung immer weniger verspreizt werden. Im Gegensatz zu einer gleichmäßigen Verspreizung wird hierdurch erreicht, dass bei einem Lastangriff an den Befestigungsmitteln des Ankergrundteils die Krafteinleitung in den Untergrund nicht vorwiegend an der dem Bohrlochgrund abgewandten Spreizhülse in geringer Bohrlochtiefe erfolgt, sondern die Krafteinleitung gleichmäßiger über alle Spreizhülsen verteilt wird. Hierdurch werden insbesondere auch Spannungsspitzen an einer einzelnen Spreizhülse vermieden.On optimized bearing behavior of the expansion anchor is achieved when the maximum expansion paths of the individual expansion sleeves from expansion sleeve to expansion sleeve in the direction of insertion of the expansion anchor become smaller. This ensures that when setting the expansion anchor, the expansion sleeve closest to the bottom of the hole is spread while the other less and less spread contrary to the direction of insertion become. In contrast to a uniform spreading is thereby achieved that during a load attack on the fasteners the anchor base the force into the ground not predominantly on the side facing away from the borehole spreader in low hole depth takes place, but the force is distributed evenly over all expansion sleeves becomes. As a result, in particular, voltage spikes on a single expansion sleeve avoided.
Zur Ausgestaltung dieser unterschiedlichen Spreizwege ist durch Variation unterschiedlicher Maße, wie der Längen und Durchmesser der reduzierten und sich erweiternden Teile der Spreizabschnitte oder der Spreizhülsen, möglich. Um eine möglichst einfache Geometrie zu erhalten, sieht eine bevorzugte Ausführungsform vor, dass lediglich die Längen der im Durchmesser reduzierten Teile der Spreizabschnitte in Einbringrichtung des Spreizankers abnimmt, während die anderen Maße unverändert bleiben.to Design of these different Spreizwege is by variation different dimensions, like the lengths and diameter of the reduced and widening parts of the Spreader sections or the expansion sleeves, possible. To get as simple as possible To obtain geometry, sees a preferred embodiment that only the lengths of the reduced in diameter parts of the expansion sections in the direction of insertion of the expansion anchor decreases while the other dimensions unchanged stay.
Die Erfindung wird nachfolgend anhand eines in der Zeichnung dargestellten Ausführungsbeispiels näher erläutert. Es zeigen:The Invention will now be described with reference to a drawing embodiment explained in more detail. It demonstrate:
