Abstract
Description
Aufzugsmontageanker mit einem Anhängeabschnitt zum Anhängen von Schäkeln, Haken, Seilen oder dergleichen und mindestens einem Verankerungsabschnitt zum Eingiessen in eine Betondecke.Elevator assembly anchor with a trailer section for attaching shackles, hooks, ropes or the like and at least one anchoring section for pouring into a concrete pavement.
In Aufzug-Maschinenräumen oder im Schachtkopfbereich von Aufzugsschächten müssen zum Anhängen von Montageplattformen zur Montage oder Wartung des Aufzuges in der Decke des Schachtes Lastanker angebracht werden, welche Lasten von mehreren Tonnen halten können. Für diese Anwendung sind lastgeprüfte Aufzugsmontageanker bekannt. Ein Beispiel für einen solchen Aufzugsmontageanker ist eine vormontierte Kombination aus einem Wellenanker (Verankerungsabschnitt) und einer Seilöse (Anhängeabschnitt). Der Wellenanker wird in die Decke des Aufzugsschachtes einbetoniert und das Anhängen von Schäkeln, Haken, Seilen oder dergleichen geschieht über die Seilöse im Schachtkopfbereich. Um Tragfähigkeiten von bis zu 4 Tonnen zu erreichen, muss ein solcher Wellenanker eine Länge von etwa 30 cm aufweisen. Die Seilöse ragt gemäss einem solchen Aufzugsmontageanker bis zu 25 cm in den Schachtkopfbereich hinein. Eine solche Konstruktion braucht eine Deckenstärke von mindestens 30 cm. Für geringere Deckenstärken, bei denen nicht beliebig viel Platz für die Verankerung vorhanden ist, sind auch kleinere Varianten bekannt. Solche kleinere Varianten sind aber nur für geringere Lasten geprüft und zugelassen.In elevator machinery rooms or in the shaft head area of elevator shafts, load anchors must be mounted in the ceiling of the shaft for attaching mounting platforms for mounting or maintaining the elevator, which can hold loads of several tons. Load-tested lift mounting anchors are known for this application. An example of such a lift mounting anchor is a preassembled combination of a shaft anchor (anchoring section) and a cable eye (attachment section). The wave anchor is concreted in the ceiling of the elevator shaft and the attachment of shackles, hooks, ropes or the like is done via the cable eye in the shaft head area. In order to achieve load capacities of up to 4 tons, such a wave anchor must have a length of about 30 cm. The cable eye protrudes up to 25 cm into the shaft head area according to such an elevator assembly anchor. Such a construction needs a ceiling thickness of at least 30 cm. For smaller ceilings, where there is not an arbitrary amount of space for anchoring, even smaller variants are known. Such smaller variants are tested and approved only for lower loads.
Gegenstand der Erfindung ist es, eine Vorrichtung der eingangs genannten Art anzugeben, bei der der Anhängeabschnitt nicht den für den Aufzug verwendbaren Platz beansprucht und die dennoch eine Tragfähigkeit für Lasten von mehreren Tonnen aufweist.The invention is to provide a device of the type mentioned, in which the appendage section does not claim the usable space for the elevator and yet has a capacity for loads of several tons.
Erfindungsgemäss wird dies bei einer solchen Vorrichtung dadurch erreicht, dass der Anhängeabschnitt in einem Aussparungskörper angeordnet ist, der ebenfalls zum Eingiessen in die Betondecke angrenzend an deren untere Schalung vorgesehen ist und der in der Betondecke nach dem Entschalen einen den Anhängeabschnitt umgebenden Hohlraum angrenzend an die Unterseite der Decke erzeugt.According to the invention, this is achieved in such a device in that the attachment portion is arranged in a recess body which is also provided for pouring into the concrete floor adjacent to the lower formwork and which in the concrete ceiling after demoulding a cavity surrounding the attachment portion adjacent to the underside the ceiling generated.
Die Erfindung hat demnach den Vorteil, dass der Aufzugsmontageanker nicht in den Schachtkopfbereich vorstösst und dabei den Platz beansprucht, welcher sonst für den Aufzug verwendet werden kann.The invention therefore has the advantage that the elevator assembly anchor does not project into the shaft head area and thereby takes up the space which can otherwise be used for the elevator.
Gemäss einer ersten bevorzugten Ausführungsform ist der erfindungsgemässe Aussparungskörper länglich ausgebildet und weist eine Länge von 12 - 25 cm, vorzugsweise 15 - 20 cm, eine Breite von 5 - 10 cm, vorzugsweise 6 - 8 cm, und eine Höhe von 4 - 10 cm, vorzugsweise 5 - 7 cm, auf. Eine längliche Form des Aussparungskörper erleichtert das Anhängen von Schäkeln, Haken, Seilen oder dergleichen. Der Aussparungskörper kann aus formstabilem Schaumstoff oder dergleichen bestehen, welcher nach der Montage durch zB. Auskratzten entfernt werden kann. Der Aussparungskörper kann auch schalenförmig mit einer Wandung aus Blech oder Kunststoff ausgebildet sein. Weiter kann der Aussparungskörper mit Mitteln zum Annageln auf der Schalung der Betondecke versehen sein.According to a first preferred embodiment, the recess body according to the invention is elongated and has a length of 12 to 25 cm, preferably 15 to 20 cm, a width of 5 to 10 cm, preferably 6 to 8 cm, and a height of 4 to 10 cm. preferably 5 - 7 cm, on. An elongate shape of the recess body facilitates the attachment of shackles, hooks, ropes or the like. The recess body may consist of dimensionally stable foam or the like, which after assembly by eg. Scraping can be removed. The recess body may also be formed shell-shaped with a wall of sheet metal or plastic. Further, the recess body may be provided with means for nailing on the formwork of the concrete ceiling.
Gemäss einer ersten bevorzugten Ausführungsform wird der Anhängeabschnitt durch einen Stab gebildet, weicher an zwei Stellen durch die Wandung des erfindungsgemässen Aussparungskörpers in den umgebenden Beton hineinreicht und dabei zwei Verankerungsabschnitte bildet. Der Stab kann vorzugsweise im Bereich des Anhängeabschnitts nach unten gebogen sein, um ein Anhängen von Schäkeln, Haken, Seilen oder dergleichen zu erleichtern. Um einen höheren Ausbruchwiderstand des Aufzugsmontageankers im Beton zu erreichen, kann der Stab im Bereich wenigstens eines Verankerungsabschnittes hochgezogen sein. Eine solche bevorzugte Ausführungsform hat den Vorteil, dass Anhänge- und Verankerungsabschnitt aus einem Stab gebildet werden. Eine solche erfindungsgemässe Vorrichtung ist leicht herzustellen und kann fest mit dem Aussparungskörper verbunden werden, um eine Montage auf der Schalung zu erleichtern.According to a first preferred embodiment, the attachment section is formed by a rod, which extends at two points through the wall of the recess body according to the invention into the surrounding concrete and thereby forms two anchoring sections. The rod may preferably be bent downwardly in the region of the attachment portion to facilitate attachment of shackles, hooks, ropes or the like. In order to achieve a higher breakout resistance of the lift mounting anchor in the concrete, the rod can in the area at least be pulled up an anchorage section. Such a preferred embodiment has the advantage that the attachment and anchoring sections are formed from a rod. Such an inventive device is easy to manufacture and can be firmly connected to the recess body to facilitate mounting on the formwork.
Gemäss einer zweiten Ausführungsform umfasst der Verankerungsabschnitt eine über dem Aussparungskörper liegende Metallplatte, welche durch die Wandung des Aussparungskörpers hindurch mit dem Anhängeabschnitt verbunden ist. Der Anhängeabschnitt kann die Form einer Öse oder Schlaufe aufweisen und kommt in der oben beschriebenen Aussparung zu liegen. Zur Lastverteilung kann die Metallplatte auf mindestens einer Seite über den Bereich der Aussparung hinausreichen. Zur weiteren Lastverteilung kann mindestens ein Stab an der Metallplatte befestigt sein. Dieser Stab reicht, vorzugsweise auf beiden Seiten, 25 - 50 cm über die Metallplatte hinaus.According to a second embodiment, the anchoring portion comprises a metal plate lying above the recess body, which is connected to the attachment portion through the wall of the recess body. The appendage portion may be in the form of an eyelet or loop and come to lie in the recess described above. For load distribution, the metal plate may extend beyond the region of the recess on at least one side. For further load distribution, at least one rod may be attached to the metal plate. This bar extends, preferably on both sides, 25 - 50 cm beyond the metal plate.
Gemäss einer dritten Ausführungsform umfasst der Verankerungsabschnitt einen Wellenanker, der sich im Beton über dem Aussparungskörper befindet und welcher durch die Wandung des Aussparungskörpers hindurch mit dem Anhängeabschnitt verbunden ist. Der Anhängeabschnitt kann die Form einer Öse oder Schlaufe aufweisen und kommt in der oben beschriebenen Aussparung zu liegen.According to a third embodiment, the anchoring portion comprises a wave anchor which is located in the concrete above the recess body and which is connected through the wall of the recess body with the appendage portion. The appendage portion may be in the form of an eyelet or loop and come to lie in the recess described above.
Vorzugsweise kann der Anhängeabschnitt in allen Ausführungsformen asymmetrisch zur Längsachse der Aussparung angebracht sein, um ein Anhängen von Schäkeln, Haken, Seilen oder dergleichen zu erleichtern.Preferably, in all embodiments, the attachment portion may be mounted asymmetrically to the longitudinal axis of the recess to facilitate attachment of shackles, hooks, ropes, or the like.

Die Ausführungsform von
Die vorbeschriebene erste Ausführungsform hat den Vorteil, dass Anhänge- und Verankerungsabschnitt 6a, 6b durch ein und denselben Stab 6 gebildet werden, was die Herstellung des Aufzugsmontageankers vereinfacht. Die Verankerungsabschnitte 6b können beliebig weit in die Betondecke 3 hineinragen. Somit kann ein sehr hoher Ausbruchwiderstand erreicht werden, was das Tragen von Lasten von mehreren Tonnen ermöglicht. Da die Verankerung waagrecht und nicht senkrecht, wie bei herkömmlichen Aufzugsmontageankem, in die Decke hineingeführt wird, kann diese Ausführungsform auch in Betondecken von geringerer Stärke verwendet werden und trotzdem Lasten von mehreren Tonnen tragen.The above-described first embodiment has the advantage that attachment and anchoring
