Description

Die Erfindung betrifft einen Anker zum Transportieren und Manipulieren von Schwerlasten, insbesondere Betonfertigteilen, mittels eines Hebe­zeuges, bestehend aus einem Ankerbolzen und einem Ankerkopf sowie gege­benenfalls einem verbreiterten Ankerfuß.The invention relates to an anchor for transporting and manipulating heavy loads, in particular precast concrete parts, by means of a lifting device, consisting of an anchor bolt and an anchor head and optionally a widened anchor base.

Solche Anker werden vielfach verwendet und zwar im Zusammenhang mit Manipulier- und Hebevorrichtungen, wie sie beispielsweise aus den AT-­PSen 283 691 und 358 788 bekannt sind.Such anchors are widely used in connection with manipulation and lifting devices, as are known for example from AT-PSs 283 691 and 358 788.

Ziel der Erfindung ist es, einen solchen Anker dahingehend zu verbessern, daß eine bessere Einleitung der Kräfte in die Schwerlast, insbesondere die Betonfertigteile, erfolgt und daß vor allem eine bessere Aufnahme der Spaltzugkräfte beim Aufstellen und eine Vermeidung von Abplatzungen er­reicht wird. Dies ist insbesondere bei dünnen Betonfertigteilen, bei niedriger Betonfestigkeit, bei Leichtbeton sowie bei Leca-, Schlacken- und Schlammbeton od.dgl. wesentlich.The aim of the invention is to improve such an anchor in such a way that a better introduction of the forces into the heavy load, in particular the prefabricated concrete parts, and that, above all, a better absorption of the splitting tensile forces during installation and avoidance of flaking is achieved. This is particularly the case with thin precast concrete parts, with low concrete strength, with lightweight concrete as well as with leca, slag and sludge concrete or the like. essential.

Dies wird bei dem eingangs näher bezeichneten Anker erfindungsgemäß dadurch erreicht, daß der Ankerbolzen in seinem an den Ankerkopf an­schließenden Drittel seiner Längserstreckung mit einer an sich bekannten Verdickung von der ungefähren Form eines Zylinders versehen ist, wobei die Achse dieses Zylinders etwa senkrecht zur Ankerbolzen-Achse angeordnet und dieser Zylinder in Richtung seiner Achse mit einem vorzugsweise kreisrunden Querloch versehen ist.This is achieved according to the invention in the anchor specified at the outset in that the anchor bolt is provided in its third of its longitudinal extension adjoining the anchor head with a known thickening of the approximate shape of a cylinder, the axis of this cylinder being approximately perpendicular to the anchor bolt axis arranged and this cylinder is provided in the direction of its axis with a preferably circular transverse hole.
