Description
Die Erfindung bezieht sich auf eine Vorrichtung zum Ankuppeln des mit Aussengewinde versehenen Proximalendes eines Schraubinjektionsankers an ein ebenfalls mit Aussengewinde versehenes Ende eines Verlängerungsrohrs, welche Vorrichtung eine Kupplungsbuchse enthält, deren Enden mit entsprechendem Innengewinde versehen sind. Eine derartige Vorrichtung ist aus der WO-A-9115656 bekannt.The invention relates to a device for Coupling the proximal end with external thread a screw injection anchor to an also with external thread provided end of an extension tube, which Device contains a coupling sleeve, the ends of which corresponding internal thread are provided. Such a device is known from WO-A-9115656.
Bei Schraubinjektionsankern handelt es sich um ein Rohr oder eine Hohlstange, das (die) wenigstens am Distalende mit einem Schraubenflügel versehen ist und das (die) drehend in den Boden hineingebracht wird. Während und/oder nach dem Eintreiben des Ankers wird durch den Hohlraum des Rohres oder der Stange ein hydraulischer Mörtel eingebracht, der durch in der Rohrwandung vorhandene Löcher in die zwischen den Schraubenflügelwindungen eingeschlossene Bodenmasse injektiert wird mit dem Zweck diese Bodenmasse zu verfestigen.Screw injection anchors are one Pipe or a hollow rod, at least at the distal end is provided with a screw wing and that (which) is rotated into the ground. While and / or after the anchor has been driven in by the Hydraulic cavity of the pipe or rod Mortar introduced by the existing in the pipe wall Holes in the between the screw wing turns enclosed soil mass is injected with the purpose to solidify this soil mass.
Derartige Schraubinjektionsanker werden in grossem Masstab zum Verankern von bodenabstützenden und/oder wasserhaltenden Bauten, zur Bodenverankerung von gegen "Auftreiben" zu sichernden Betonbauten und dergleichen verwendet.Such screw injection anchors are large Scale for anchoring floor-supporting and / or water-retaining structures, for ground anchoring against "Exposure" to be secured concrete buildings and the like used.
In Abhängigkeit der Tiefe, bis auf welche der Anker eingetrieben werden muss, wird eine grössere oder kleinere Anzahl von Verlängerungsrohren verwendet.Depending on the depth to which the anchor must be driven in, becomes larger or smaller Number of extension tubes used.
Die anfangs beschriebene Kupplungsbuchse ist ein bekanntes, einfaches, billiges und wirksames Mittel zum Verbinden des eigentlichen Ankerkörpers mit einem Verlängerungsrohr und auch zum gegenseitigen Kuppeln von Verlängerungsrohren.The coupling bush described at the beginning is a known, simple, cheap and effective means of Connect the actual anchor body with an extension tube and also for the mutual coupling of Extension tubes.
Beim Einschrauben des Ankers in den Boden, zu dem im Allgemeinen ein sehr grosses Drehmoment ausgeübt werden muss, drehen sich der Ankerkörper und das Verlängerungsrohr in der Regel so fest in die Kupplungsbuchsen, dass das Losdrehen eines einmal in den Boden eingetriebenen Verlängerungsrohres, ohne zugleicherzeit auch die tieferliegenden Verlängerungsrohre zu Lösen, schwer wird.When screwing the anchor into the ground to which the Generally a very large torque can be exerted the anchor body and the extension tube rotate usually so tight in the coupling bushings that the loosening of a once driven into the ground Extension tube, without the lower ones at the same time It becomes difficult to loosen extension tubes.
Letzteres ist z.B. ein Problem, wenn es sich handelt um das gegen "Auftreiben" Verankern von Betonbauten, wie unter der Erdoberkannte anzubringenden Betonsohlen. In einem derartigen Fall muss ein von der Erdoberkannte eingetriebener Anker bis auf die Tiefe des zu verankernden Betonwerkes abgekürzt werden und zwar vor dem Ausgraben der für die Herstellung des Betonwerkes benötigte Baugrube. Dazu wird in der Regel von jedem Anker das zuletzt eingebrachte Verlängerungsrohr weggenommen.The latter is e.g. a problem if it is to prevent the "floating" of concrete structures, such as concrete soles to be installed under the ground level. In In such a case, one must driven anchor to the depth of the anchor Concrete plant are abbreviated before excavation the construction pit required for the manufacture of the concrete plant. This is usually the last of each anchor inserted extension tube removed.
In der Praxis kommt es nunmehr vor, dass das zuletzt eingebrachte Verlängerungsrohr fester als ein zuvor eingebrachte Verlängerungsrohr sitzt, sodass das von der Erdoberkannte Ausnehmen des zuletzt eingebrachten Verlängerungsrohres nicht möglich ist, ohne dabei zugleicherzeit ein zuvor eingebrachtes Verlängerungsrohr mitzunehmen. In einem solchem Fall muss an der betreffenden Stelle gegraben werden um die letzte Kupplungsbuchse "blosszulegen".In practice it now happens that the last inserted extension tube firmer than a previously inserted Extension tube sits, so that from the top of the earth Removing the last extension tube inserted is not possible without at the same time to take a previously inserted extension tube with you. In Such a case must be dug at the location concerned to "expose" the last coupling bush.
Die Erfindung beabsichtigt nunmehr für solche Fälle eine billige und wirksame Lösung zu bieten, ohne damit die Wirksamkeit beim Eintreiben zu beeinträchtigen.The invention now intends for such cases to offer a cheap and effective solution without sacrificing the Impact effectiveness in driving.
Insbesondere wird beabsichtigt, eine Vorrichtung zum Ankuppln eines letzten Verlängerungsrohres zu schaffen, welche sich unter allen Umständen leichter als die herkommliche Kupplungsbuchse lösen lässt und welche weiterhin in genügendem Masse leckdicht ist und den Kostpreis des Ankers nicht oder kaum beeinträchtigt.In particular, it is intended to provide a device for To create a last extension tube, which is easier than the conventional one under all circumstances Coupling bush can be released and which still is leakproof to a sufficient extent and the cost price of the Anchor not affected or hardly affected.
Erfindungsgemäss wird dieser Zweck erreicht mit einer gattungsgemässen Vorrichtung, welche dadurch gekennzeichnet ist, dass die Kupplungsbuchse mit einer zweiten Kupplungsbuchse zusammenarbeitet, deren eine Hälfte der ersten Kupplungsbuchse ähnlich ist und deren zweite Hälfte in der Weise erweitert und ausgeführt ist, dass sie dichtend über ein Endteil der ersten Kupplungsbuchse passt, wobei die erweiterte Kupplungsbuchsenhälfte mit mindestens einem, vom Stirnrand derselben ausgehenden Bajonettschlitz versehen ist, welcher mit einem an einer Stelle zwischen den Enden der ersten Kupplungsbuchse radial nach aussen ragenden Zapfen zusammenarbeitet.According to the invention, this purpose is achieved with a Generic device, which is characterized is that the coupling bush with a second coupling bush works together, one half of which first coupling bush is similar and the second half is expanded and executed in such a way that it is sealing fits over an end part of the first coupling bush, the extended coupling bushing half with at least a bayonet slot starting from the front edge of the same is provided, which with a at a point between the ends of the first coupling bush radially outwards protruding spigot works together.
Die erfindungsgemäss vorgeschlagene Kupplungsvorrichtung ist also tatsächlich eine Kombination von zwei Kupplungsbuchsen. Im Gebrauch bleibt die eine Kupplungsbuchse, welche etwa der üblichen Kupplungsbuchse entspricht, als verlorener Teil im Boden sitzten, genau wie dies für die herkommliche Buchse gilt, während die zweite Kupplungsbuchse mit ihrem erweiterten und mit einem Bajonettschlitz versehenen Ende unter den Umständen, wofür die erfindungsgemässe Vorrichtung bestimmt ist, zurückgewonnen wird und somit mehrmalig benützt werden kann.The coupling device proposed according to the invention is actually a combination of two Coupling bushes. One coupling socket remains in use, which corresponds approximately to the usual coupling bush, sitting in the floor as a lost part, just like this applies to the traditional socket, while the second Coupling socket with its extended and with a bayonet slot provided end under the circumstances for which the device according to the invention is recovered and can therefore be used several times.
Zu bemerken ist, dass aus der Amerikanischen Patentschrift US 3 664 444 A ein aus mehreren Längsabschnitten zusammengesetzter Erdbohrer bekannt ist, wobei je zwei Längsabschnitte mit einer Innenbuchse und einer Aussenbuchse ineinanderstecken und wobei ein an der Innenumfangsfläche der Aussenbuchse vorgesehener Keil in einem an der Aussenumgangsfläche der Innenbuchse vorgesehenen Bajonetschlitz eingreift. Wesentlich dabei ist die Verwendung eines Sicherungskeiles, mit Hilfe dessen die beiden Abschnitte fest miteinander verbunden werden. Eine unter der Erdoberkante liegende Verbindung zwischen zwei Bohrerabschnitte lässt sich nicht einfach nach Art eines Bajonettverschlusses lösen.It should be noted that from the American patent US 3 664 444 A one of several longitudinal sections composite earth drill is known, two each Longitudinal sections with an inner bush and an outer bush plug into each other with one on the inner circumferential surface the wedge provided in one the outer circumferential surface of the inner socket Bayonet slot engages. The use is essential a safety wedge, with the help of which the two Sections are firmly connected. One under the connection between two drill sections located above the ground cannot simply be like a bayonet lock to solve.
