Description

Die Erfindung betrifft eine Hebe- und Transportvorrichtung für schwere Lasten, wie Betonfertigteile, die an einer Krafteinleitungsfläche des Betonfertigteils angreift, und die einen Kupplungskopf mit einer durchgehenden Öffnung beinhaltet, deren Durchgriffsöffnung im wesentlichen in einer vertikalen Aufstell- und Transportebene und parallel zur Krafteinleitungsfläche liegt sowie ein Schäkel, das mit seinem unteren Anschlußende diese Öffnung kettengliedartig durchgreift, so daß die Ebene des Anschlußendes im wesentlichen in der Aufstell- und Transportebene liegt.The invention relates to a lifting and transport device for heavy loads, such as prefabricated concrete parts, which engages a force introduction surface of the precast concrete element and which includes a coupling head with a through opening, the passage opening of which lies essentially in a vertical installation and transport plane and parallel to the force introduction surface, and also a shackle which, with its lower connecting end, extends through this opening in the manner of a chain link, so that the plane of the connecting end lies essentially in the installation and transport plane.

Eine derartige Vorrichtung ist aus der DE-C-2720148 (Figur 1) bekannt. Bei dieser vorbekannten Vorrichtung verbreitert sich das Schäkel nach oben hin, wobei es an seinem unteren Teil eine Durchgriffsöffnung aufweist, so daß das kettengliedartige Eingreifen in den Kupplungskopf entsteht.Such a device is known from DE-C-2720148 (Figure 1). In this previously known device, the shackle widens upward, and has a through opening on its lower part, so that the chain link-like engagement in the coupling head is produced.

Es hat sich in der Praxis gezeigt, daß bei einer derartigen Ausbildung des Schäkels Schwierigkeiten insbesondere beim Aufstellen eines liegenden Betonfertigteils, also bei parallel zur Stirnseite des Fertigteils zeigender Zugrichtung, auftreten können. Insbesondere bei tiefstmöglicher Verankerung des Ankers im Betonfertigteil und dementsprechend tiefem Eintauchen des Kupplungskopfes in die entsprechende Ausnehmung im Betonfertigteil kann es vorkommen, daß die Schmalseite des Schäkels an die Stirnseite des Betonfertigteils anstößt und dort Beschädigungen hervorruft. Diese Gefahr wird noch vergrößert, wenn das Betonfertigteil an der Stirnseite herausragende Nasen oder Rippen aufweist, wie dies beispielsweise bei Decken- oder Wandelementen gebräuchlich ist. Hierbei kann es beim Manövrieren des Betonfertigteils durch entsprechende Schwenkbewegungen des Schäkels zu einem Abplatzen dieser besonders exponierten Bereiche des Betonfertigteils kommen. Diese Schwierigkeiten nehmen erfahrungsgemäß mit abnehmender Dicke des Betonfertigteils zu, da der für die Schwenkbewegungen des Schäkels zur Verfügung stehende Raum auf ein Minimum schrumpft.It has been shown in practice that with such a design of the shackle, difficulties can arise, in particular when erecting a horizontal precast element, that is to say with the direction of pull pointing parallel to the end face of the precast element. Particularly when the anchor is anchored as deeply as possible in the precast concrete element and accordingly the plunger head is deeply immersed in the corresponding recess in the precast concrete element, it may happen that the narrow side of the shackle abuts the end face of the precast concrete element and causes damage there. This danger is further increased if the precast concrete part has protruding noses or ribs on the end face, as is customary, for example, in the case of ceiling or wall elements. When the precast element is maneuvered, corresponding swiveling movements of the shackle can cause these particularly exposed areas of the precast element to flake off. Experience has shown that these difficulties increase with decreasing thickness of the precast concrete part, since the space available for the pivoting movements of the shackle shrinks to a minimum.

Aufgabe der Erfindung ist es, den Kraftangriffspunkt möglichst nahe an die Fläche, über die die Kraft von der Hebe- und Transportvorrichtung eingeleitet wird, heranzurücken und beim Handhaben des Betonteils diese Fläche nicht zu beschädigen.The object of the invention is to move the force application point as close as possible to the surface over which the force is applied by the lifting and transport device and not to damage this surface when handling the concrete part.

Diese Aufgabe wird dadurch gelöst, daß das Anschlußende etwa in Form eines Ringes ausgebildet ist, und daß die Dicke des Schäkels zumindest in der Ringebene und wenigstens über den an den Ring anschließenden und der Krafteinleitungsfläche des Betonfertigteils unmittelbar gegenüberliegenden Teil geringer ist als der Ringdurchmesser, so daß selbst bei zur Krafteinleitungsfläche paralleler Zugrichtung der Kraft an der Öffnung das ringförmige Anschlußende des Schäkels in eine Aussparung des Betonfertigteils bis zu einer Tiefe eintauchen kann, bei der der Angriffspunkt des Anschlußendes am Kupplungskopf innerhalb eines Bereiches liegt, der geringer ist als der Außenradius des ringförmigen Anschlußendes.This object is achieved in that the connection end is approximately in the form of a ring, and that the thickness of the shackle is at least in the ring plane and at least over the part immediately adjacent to the ring and the force application surface of the precast concrete part less than the ring diameter, so that even with the direction of force parallel to the force of the force at the opening, the annular connection end of the shackle can be immersed in a recess in the precast concrete to a depth at which the point of engagement of the connection end on the coupling head is within a range which is less than the outer radius of the annular Connecting end.

Durch diese Ausgestaltung des Schäkels weist dieses in der beim Aufstellen eines Betonfertigteiles entscheidenden Ankerebene nur eine sehr geringe Ausdehnung auf, so daß ein Anstoßen oder Anschlagen an das Betonfertigteil auch dann ausgeschlossen ist, wenn die Zugrichtung parallel zur Stirnfläche des Betonfertigteils liegt.Due to this configuration of the shackle, this has only a very small extension in the anchor plane that is decisive when setting up a precast concrete element, so that bumping or striking against the precast concrete element is also ruled out if the pulling direction is parallel to the end face of the precast concrete element.

Hierbei kann der Anker tiefer im Beton liegen. Daraus resultiert ein größerer Ausbruchkegel und somit eine wesentlich bessere Verankerung im Beton, was insbesondere beim Drehen und Wenden unter Last von Bedeutung ist.The anchor can lie deeper in the concrete. This results in a larger excavation cone and thus a much better anchorage in the concrete, which is particularly important when turning and turning under load.

Außerdem kann beim späteren Verguß der Aussparung mit Beton eine wesentlich höhere Betonüberdeckung und somit ein verbesserter Korrosionsschutz der Anker erreicht werden.In addition, when the recess is later potted with concrete, a significantly higher concrete coverage and thus improved corrosion protection of the anchors can be achieved.

Die erfindungsgemäße Ausgestaltung des Schäkels gewährleistet auch, daß bei Verschwenkungen des Schäkels gegen eine möglicherweise am Rand des Betonfertigteils sitzende Rippe bis zu einem gewissen Winkel keine Berührung mit diesem exponierten Bereich des Betonfertigteils stattfindet, was im praktischen Einsatz wesentlich ist. Auch bei derartigen speziellen Betonfertigteilen ist somit ein Schwenkwinkel von mehr als 90° gewährleistet.The design of the shackle according to the invention also ensures that when the shackle is pivoted against a rib possibly sitting at the edge of the precast concrete element, there is no contact with this exposed area of the precast concrete element, which is essential in practical use. Even with such special precast concrete parts, a swivel angle of more than 90 ° is guaranteed.

Aus der DE-B-2617866 ist eine Anschlagvorrichtung für Betonfertigteile bekannt, bei der ein Schäkel ein Trägerteil 13 kettengliedartig durchgreift. Hierbei besteht das Schäkel aus einem Schäkelkörper (Anschlagöse 16) und einer den Schäkelkörper gegenüber dem Betonfertigteil abstützenden Schraubenfeder 27, die den Schäkelkörper federnd in einer etwa senkrecht aus der Anschlageinrichtung herausragenden Stellung halten soll. Zwar weist auch bei dieser vorbekannten Vorrichtung das Anschlußende des Schäkeikörpers die Form eines Ringes auf und der Schäkelkörper ist über einen Teil seiner Gesamtlänge gegenüber dem Ringdurchmesser verjüngt, jedoch hat diese Formgebung des Schäkelkörpers (Ösenteil 16) auf die Funktion der Anschlagvorrichtung keine Auswirkungen ; sie dient lediglich dazu, einen weit genug vom Gehäuse 11 weg gelegenen Abstützbereich für die Spiralfeder 27 zu schaffen.From DE-B-2617866 a stop device for precast concrete parts is known, in which a shackle passes through a carrier part 13 like a chain link. Here, the shackle consists of a shackle body (lifting eye 16) and a coil spring 27 which supports the shackle body with respect to the precast concrete part and which is intended to hold the shackle body resiliently in a position which projects approximately perpendicularly from the stop device. In this known device, too, the connecting end of the shackle body has the shape of a ring and the shackle body is tapered over part of its entire length relative to the ring diameter, but this shape of the shackle body (eyelet part 16) has no effect on the function of the stop device; it merely serves to create a support area for the coil spring 27 which is located far enough away from the housing 11.

Der Kraftangriffspunkt des Schäkelkörpers am Kupplungskopf liegt relativ weit von der Oberfläche der Seite entfernt, an der die Anschlageinrichtung angreift, außerdem benutzt die vorbekannte Anschlageinrichtung ein relativ voluminöses Gehäuse 11, das im Betonfertigteil untergebracht werden muß. Insbesondere bei der Verwendung der vorbekannten Anschlagvorrichtung zum Heben und Transportieren von schmalen Betonfertigteilen kommt daher nur eine Anordnung in Frage, wie sie in Figur 2 der vorbekannten Druckschrift dargestellt ist, da in dieser Ebene die Schmalseite des Gehäuses 11 liegt. Hierbei ist der mögliche Schwenkwinkel beim Anheben aber ausschließlich durch die große Behinderung durch die Schraubenfeder 27 gegeben, da es bei einer Aufstellbewegung in der Ebene der Figur 2 der vorbekannten Druckschrift auf die Formgebung des Schäkelkörpers 16 in der dazu senkrechten Ebene ohnehin nicht ankommt.The point of force application of the shackle body to the coupling head is relatively far from the surface of the side on which the stop device acts, and the known stop device also uses a relatively voluminous housing 11 which has to be accommodated in the precast concrete part. In particular, when using the previously known stop device for lifting and transporting narrow precast concrete parts, only one arrangement is possible, as shown in FIG. 2 of the previously known pressure Scripture is shown, since the narrow side of the housing 11 is in this plane. Here, the possible swiveling angle when lifting is given solely by the large impediment caused by the helical spring 27, since the shape of the shackle body 16 in the plane perpendicular to it does not matter in any case during a set-up movement in the plane of FIG. 2 of the previously known document.

Die Formgebung des Schäkelkörpers 16 bei der DE-B-2617866 hat folglich keine Bedeutung für die Funktion dieser vorbekannten Anschlageinrichtung bei der Behandlung von Betonfertigteilen, insbesondere dünnen Betonfertigteilen, die oben definierte Aufgabenstellung der Erfindung ist mit der vorbekannten Anordnung nicht lösbar.The shape of the shackle body 16 in DE-B-2617866 is consequently of no importance for the function of this known anchor device in the treatment of precast concrete parts, in particular thin precast concrete parts, the object of the invention defined above cannot be solved with the known arrangement.

Aus der US-A-3 640 555 ist eine Kupplungsvorrichtung bekannt, bei der zur vereinfachten Halterung von tragbaren Handwerkzeugen das zu betätigende Werkzeug mit einem Gegengewicht verbindbar ist. Diese Kupplungseinrichtung besteht aus einer Öse 16 am Handwerkzeug, in die ein ringförmiges Kupplungsglied B klauenartig eingreifen kann. Dieses Kupplungsglied B ist über einen speziellen Mechanismus mit einem schäkelähnlichen Kupplungsglied A kuppelbar, von dem aus ein Seilzug zum Gegengewicht führt. Diese vorbekannte Vorrichtung dient zum sicheren Halten des Handwerkzeuges ohne die Gefahr einer unbeabsichtigten Entkoppelung, seine Funktion ist insoweit als « statisch zu bezeichnen, da die Wirkungslinie dieser Kupplungsvorrichtung grundsätzlich die Vertikale ist, auf Besonderheiten des gehaltenen Bauteils, des Handwerkzeuges, kommt es hierbei nicht an, insbesondere spielen Fragen der Krafteinleitung und des Kraftangriffspunktes von dieser Kupplungseinrichtung in das gehaltene Handwerkzeug erkennbar keine Rolle.From US-A-3 640 555 a coupling device is known in which the tool to be actuated can be connected to a counterweight in order to simplify holding of portable hand tools. This coupling device consists of an eyelet 16 on the hand tool, into which an annular coupling member B can engage like a claw. This coupling element B can be coupled via a special mechanism to a shackle-like coupling element A, from which a cable pull leads to the counterweight. This known device is used to hold the hand tool securely without the risk of unintentional decoupling, its function can be described as "static", since the line of action of this coupling device is basically the vertical, special features of the component being held, the hand tool, are not important here , In particular, questions of the introduction of force and the point of force application from this coupling device into the hand tool held recognizably play no role.

Eine vorteilhafte Ausgestaltung der Erfindung sieht vor, daß das Schäkel zweiteilig ausgebildet ist, wobei der ringförmige Endbereich durch ein Ösenteil und der anschließende Bereich durch ein Anschlußteil gebildet ist, die so kraftschlüssig miteinander verbunden sind, daß ihre Ebenen maximaler Ausdehnung senkrecht aufeinander stehen.An advantageous embodiment of the invention provides that the shackle is formed in two parts, the annular end region being formed by an eyelet part and the adjoining region being formed by a connecting part which are connected to one another in a force-locking manner such that their planes of maximum extension are perpendicular to one another.

Der Grundgedanke dieser Ausbildung besteht darin, die für das Anschlußteil erforderliche statische Belastbarkeit dadurch sicherzustellen, daß die maximale Ausdehnung des Anschlußteils in der Ebene liegt, in der sie am wenigsten stört, nämlich in Aufstellposition der erfindungsgemäßen Vorrichtung in der zur Stirnseite des Betonfertigteils parallelen Ebene.The basic idea of this design is to ensure the static load-bearing capacity required for the connecting part by ensuring that the maximum extent of the connecting part lies in the plane in which it is least disturbing, namely in the installation position of the device according to the invention in the plane parallel to the end face of the precast concrete part.

In weiterer Ausgestaltung ist vorgesehen, daß das Anschlußteil einen am Ösenteil angeformten Ansatz gabelartig übergreift und mit diesem verschweißt ist.In a further embodiment it is provided that the connecting part engages over a projection which is formed on the eyelet part and is welded to it.

Diese Lösung ermöglicht eine konstruktiv einfache Realisierung und sichert die statische Belastbarkeit des Schäkels im Übergangsbereich zwischen Ösenteil und Anschlußteil.This solution enables a structurally simple implementation and ensures the static load capacity of the shackle in the transition area between the eyelet part and the connecting part.

Weitere Ausgestaltungen sind weiteren Unteransprüchen zu entnehmen.Further refinements can be found in further subclaims.

Dieser Kupplungskopf weist eine zentrale Öffnung 21 zum Durchgriff des Schäkels 10 auf, sowie an seiner Unterseite einen radialen Schlitz, mit dem er einen im Betonfertigteil verankerten Anker 30 übergreift und mittels eines bogenförmigen, durch eine Öffnung im Anker führbaren Riegels festhält.This coupling head has a central opening 21 for the shackle 10 to pass through, and on its underside a radial slot with which it engages over an anchor 30 anchored in the prefabricated concrete part and holds it by means of an arcuate bolt which can be guided through an opening in the anchor.

In bekannter Weise weist das Anschlußteil 12 ein Auge 12c zur Befestigung eines Seiles, Kranhakens oder ähnlichem auf.The shackle 10 consists of an annular eyelet part 11 which extends through the coupling head 20 and a connecting part 12, the lower end of which is fork-shaped; the two fork ends 12a, 12b overlap a shoulder 11a on the eyelet part 11, both parts are welded together in their adjacent areas. In a known manner, the connecting part 12 has an eye 12c for fastening a rope, crane hook or the like.

Durch dieses Aufeinanderstecken der beiden Bauteile, Ösenteil 11 und Anschlußteil 12 erstreckt sich das Ösenteil 11 in einer Ebene, die senkrecht zur Hauptausdehnungsebene des Anschlußteils 12 liegt. Die beiden Teile sind also sozusagen um 90° gegeneinander versetzt aufeinander gesteckt und verschweißt.By plugging the two components, eyelet part 11 and connecting part 12 onto one another, the eyelet part 11 extends in a plane that is perpendicular to the main plane of expansion of the connecting part 12. The two parts are thus, so to speak, staggered and welded at 90 ° to one another.

Die Figur 3 zeigt, welche praktischen Vorteile diese Ausbildung hat: Das Betonfertigteil 40 mit Anker 30 liegt horizontal auf einer Ebene und das Schäkel 10 greift parallel zur Stirnseite des Betonfertigteils 40 am Kupplungskopf 20 an (Angriffspunkt A). Durch die ringförmige Ausbildung des Ösenteils 11 kann dieses in eine entsprechend dimensionierte Aussparung 40b des Betonfertigteils 40 eintauchen, so daß der Abstand a des Angriffspunktes A von der stirnseitigen Oberfläche des Betonfertigteils 40 auf ein Minimum reduziert ist. Durch die erfindungsgemäße Gestaltung des Schäkels ergibt sich damit auch eine Vergrößerung der Betonüberdeckung des Ankers 30 um das Maß b gegenüber dem Einsatz des vorbekannten Schäkels.FIG. 3 shows the practical advantages of this design: the precast concrete part 40 with anchor 30 lies horizontally on one level and the shackle 10 engages the coupling head 20 parallel to the end face of the precast concrete part 40 (point of application A). Due to the ring-shaped design of the eyelet part 11, the latter can be immersed in a correspondingly dimensioned recess 40b of the precast concrete part 40, so that the distance a of the point of application A from the front surface of the precast concrete part 40 is reduced to a minimum. The inventive design of the shackle also results in an increase in the concrete coverage of the anchor 30 by the dimension b compared to the use of the previously known shackle.

Figur 4 zeigt die räumliche Zuordnung der beteiligten Bauteile beim Transport der Fertigteilplatte 40, der Anker 30 und die Betonfertigteilplatte 40 hängen hier vertikal am Schäkel 10. Durch den um das Maß b gegenüber der bekannten Lösung tiefer sitzenden Anker 30 liegt hier beim Transport der Fertigteilplatte 40 der Kraftangriffspunkt A etwa in der Stirnfläche des Betonfertigteils 40. Es ist nun ohne weiteres zu erkennen, daß beim Transport und Aufstellen des Betonfertigteils 40 oder sonstigen Manipulationen Verschwenkungen des Schäkels 10 auftreten können, ohne daß dadurch die vorspringende Rippe 40a beschädigt wird.Figure 4 shows the spatial assignment of the components involved in the transport of the finished part plate 40, the anchor 30 and the precast concrete slab 40 hang here vertically on the shackle 10. Because of the anchor 30, which is lower by dimension b than the known solution, the force application point A is located approximately in the end face of the precast concrete 40 during transport of the precast slab 40. It it can now be readily seen that during transport and installation of the precast concrete element 40 or other manipulations, the shackle 10 can pivot without damaging the projecting rib 40a.

Figur 5 zeigt eine Weiterbildung, die darin besteht, daß das Ösenteil 11 und das Anschlußteil 12 lösbar miteinander verbunden sind. Hierzu ist das Ösenteil 11 durch geeignete Warmverformung derart ausgebildet, daß der Ansatz 11 a an seinem oberen Ende aus zwei halbzylindrischen Teilen besteht, auf die ein Gewinde aufgeschnitten wird.Figure 5 shows a development which consists in the fact that the eyelet part 11 and the connecting part 12 are detachably connected to each other. For this purpose, the eyelet part 11 is formed by suitable hot deformation such that the projection 11 a at its upper end consists of two semi-cylindrical parts, on which a thread is cut.

Korrespondierend dazu weist das Anschlußteil 12 anstelle der beiden Gabelenden 12a, 12b an seinem unteren Ende einen Hohlzylinder auf, in den ein Innengewinde 12b eingeschnitten ist.Correspondingly, instead of the two fork ends 12a, 12b, the connecting part 12 has a hollow cylinder at its lower end, into which an internal thread 12b is cut.

Durch diese konstruktiven Ausgestaltungen ergeben sich nunmehr vielfältige Möglichkeiten, insofern, als durch eine Art Bausatzsystem durch verschiedene Formen von Ösenteil 11 und Anschlußteil 12 individuell verschiedene Schäkeiformen aufgebaut werden können, die insbesondere auf speziell geformte Betonfertigteile oder beispielsweise « schwierig » liegende Anker angepaßt sind.These constructive designs now result in a wide range of possibilities, insofar as different types of shackle shapes can be built up individually using a type of kit system using different shapes of eyelet part 11 and connecting part 12, which are particularly adapted to specially shaped precast concrete parts or, for example, “difficult” anchors.

Figur 5 zeigt ein erstes Ausführungsbeispiel, bei dem ein Anschlußteil 12 in « konventioneller » Formgebung über eine Gewindehülse 13 und eine Schraube 14 mit dem Östenteil 11 verbunden ist. Über eine Bohrung in der Gewindehülse 13 kann die Schraube 14 festgesetzt werden. Diese Variante ist insbesondere dann sinnvoll, wenn eine möglichst große Bewegungsfreiheit des Schäkels nach allen Richtungen gegeben sein soll, da der durch die Gewindehülse 13 gebildete schlanke, lange .Hals des Ösenteils 11 praktisch nicht störend in Erscheinung treten kann.FIG. 5 shows a first exemplary embodiment in which a connecting part 12 is connected to the eyelet part 11 in a “conventional” shape via a threaded sleeve 13 and a screw 14. The screw 14 can be fixed via a bore in the threaded sleeve 13. This variant is particularly useful when the shackle should be as free as possible in all directions, since the slim, long neck of the eyelet part 11 formed by the threaded sleeve 13 can practically not be a nuisance.

Eine zweite Variante zeigen die Figuren 6 und 7, hierbei ist auf die Zwischenschaltung einer Gewindehülse verzichtet, das Ösenteil 11 ist direkt in das Innengewinde 12b des Anschlußteils 12 eingeschraubt. Bei diesem Ausführungsbeispiel ist das Anschlußteil 12 hinsichtlich seiner Formgebung ähnlich ausgebildet wie das Ösenteil 11, insbesondere weist es eine vergleichbar ausgestaltete Öse auf, durch die ein Seil 15 durchgelegt werden kann. Ein derart ausgebildetes Schäkel stellt damit praktisch ein Doppelgelenk dar mit einem Maximum an allseitiger Gelenkigkeit und Beweglichkeit.A second variant is shown in FIGS. 6 and 7, in which case a threaded sleeve is not interposed, the eyelet part 11 is screwed directly into the internal thread 12b of the connecting part 12. In this embodiment, the shape of the connecting part 12 is similar to that of the eyelet part 11, in particular it has a comparable eyelet through which a rope 15 can be put. A shackle designed in this way thus practically represents a double joint with maximum flexibility and mobility on all sides.
