Abstract
Description
Die vorliegende Patentanmeldung betrifft ein Verankerungselement zur Verankerung in einem Bohrloch in einem Untergrund, der im Oberbegriff des Patentanspruchs 1 genannten Art.The present patent application relates to an anchoring element for anchoring in a borehole in a subsurface, referred to in the preamble of claim 1. Art.
Bei derartigen Verankerungselementen ist es aus der US 4,655,645 bekannt, einen Zweikomponentenmörtel über das manuell oder maschinell in Drehung versetzte Verankerungselement zu mischen. Dazu weist das Verankerungselement ein, am hinteren und zentralen Bereich des Schaftes angeordnetes Mischelement auf, dass simultan mit dem Verankerungselement in Drehung versetzt werden kann und hierzu mit diesem fest verbunden ist. In der Anwendung wird zunächst eine Patrone mit einen Zweikomponentenmörtel in ein Bohrloch eingeführt, und dann das Verankerungselement in das Bohrloch eingeschraubt. Mit dem bohrlochseitigen Ende des Verankerungselements wird beim Erreichen der Patrone diese zunächst zerstört, so dass die Komponenten des Mörtels aus dieser austreten und bei einem weiteren Eindrehen des Verankerungselements am Schaft entlang in Richtung der Bohrlochmündung migrieren, wo sie über das sich mitdrehende Mischelement vermengt werden.In such anchoring elements, it is known from US 4,655,645 to mix a two-component mortar on the manually or mechanically rotated in the anchoring element. For this purpose, the anchoring element, arranged on the rear and central portion of the shaft mixing element that can be simultaneously set in rotation with the anchoring element and is firmly connected thereto. In use, a cartridge having a two-component mortar is first introduced into a borehole, and then the anchoring element is screwed into the borehole. With the borehole-side end of the anchoring element, upon reaching the cartridge, the latter is first destroyed, so that the components of the mortar emerge from this and migrate further along the shaft in the direction of the borehole mouth as the anchoring element is screwed in, where they are mixed via the rotating mixing element.
Von Nachteil ist dabei, dass für das Mischen der Komponenten des Mörtels das Verankerungselement aktiv gedreht werden muss, was sehr zeitaufwändig sein kann. Dieses ist insbesondere dann von Nachteil, wenn das Verankerungselement bereits durch ein einfaches Einschlagen in das Bohrloch in demselben verankert werden soll, wie dies bei modernen Systemen der Fall ist.The disadvantage here is that for the mixing of the components of the mortar, the anchoring element must be actively rotated, which can be very time consuming. This is particularly disadvantageous if the anchoring element should already be anchored in the same by a simple hammering into the well, as is the case in modern systems.
Die Aufgabe der vorliegenden Erfindung liegt daher darin, ein Verankerungselement der vorgenannten Art zu entwickeln, das die vorgenannten Nachteile vermeidet. Dieses wird erfindungsgemäss durch die in Anspruch 1 genannten Massnahmen erreicht, denen folgende besondere Bedeutung zukommt.The object of the present invention is therefore to develop an anchoring element of the aforementioned type, which avoids the aforementioned disadvantages. This is achieved according to the invention by the measures mentioned in claim 1, which have the following special significance.
Demnach liegt die Besonderheit des erfindungsgemässen Verankeruogselements darin, am Verankerungsteil einen automatischen Antrieb für das oder die Mischelemente vorzusehen, der über ein Auslösemittel aktivierbar ist. Ferner ist ein kraftspeicher für Bewegungsenergie vorgesehen, der als Antrieb für das oder die Mischelemente fungiert, bzw. diesen mit Energie versorgt. Der Kraftspeicher kann bereits bei der Produktion des Verankerungselements "geladen" und über das Auslösemittel, das gleichzeitig auch als Sicherungsmittel dient, vor einer Vorzeitigen Abgabe der gespeicherten Bewegungsenergie geschützt werden. Das Verankerungsmittel ist für den Anwender also direkt Einsatzbereit. Für den Anwender ergibt sich durch diese Massnahme eine erhebliche Zeitersparnis, da er nicht mehr wie bisher mit einem Zusatzgerät, wie z. B. mit einer an den Lastangriffsteil des Verankerungselements angekoppelten Bohrmaschine eine Drehbewegung auf die Mischelemente induzieren braucht, um ein Durchmischen des Mehrkomponentenmörtels zu erreichen.
So kann der Anwender beispielsweise zunächst eine Folien- oder Glaspatrone, die wenigstens zwei pastöse Reaktionskomponenten enthält, in ein vorgefertigtes Bohrloch einbringen. Das Verankerungselement, wie z. B. eine aktiv mischende Ankerstange wird dann in das Bohrloch eingeschoben und z. B. mittels eines Hammers bis auf den Bohrlochboden eingetrieben. Dabei wird die Mörtelpatrone zerstört und es treten die Reaktionskomponenten ins Bohrloch aus, wo sie sich verteilen. Das Auslösemittel, wie z. B. ein Sperrstift, ein Sicherungsring etc. kann danach entfernt werden, so dass das oder die Mischelemente in über den automatischen Antrieb in eine Mischbewegung versetzt wird, die eine Durchmischung der Reaktionskomponenten bewirkt.Accordingly, the peculiarity of the anchoring element according to the invention lies in providing on the anchoring part an automatic drive for the mixing element (s) which can be activated via a triggering means. Furthermore, an energy accumulator for kinetic energy is provided, which acts as a drive for the mixing elements or supplies them with energy. The energy storage device can already be "charged" during the production of the anchoring element and protected against premature release of the stored kinetic energy via the triggering means, which at the same time also serves as securing means. The anchoring means is therefore ready for use directly for the user. For the user results from this measure a considerable time savings, since he is no longer with an additional device such. B. with a coupled to the load application part of the anchoring element drill a rotary motion on the mixing elements needs to achieve a thorough mixing of the multi-component mortar.
For example, the user can first introduce a foil or glass cartridge containing at least two pasty reaction components into a prefabricated borehole. The anchoring element, such as. B. an actively mixing anchor rod is then inserted into the wellbore and z. B. driven by a hammer down to the bottom of the hole. In the process, the mortar cartridge is destroyed and the reaction components emerge into the borehole, where they spread out. The triggering agent, such as. B. a locking pin, a retaining ring, etc., can be removed afterwards, so that the mixing element or elements is placed in over the automatic drive in a mixing movement, which causes a mixing of the reaction components.
Gemäss Anspruch 2 kann der oder jeder Speicher bzw. Kraftspeicher, als Federlement ausgeführt sein, das bereits bei der Produktion des Verankerungselements vorgespannt wird, und mit einem Ende am Verankerungsteil und mit seinem anderen Ende an dem oder den Mischelementen festgelegt ist. Das Festlegen an dem oder den Mischelementen kann dabei unmittelbar, oder mittelbar unter Zwischenschaltung eines oder mehrerer weiterer Bauteile erfolgen. Durch diese Massnahme ist eine sehr einfache Ausgestaltung des automatischen Antriebs möglich. Die Federelemente können z. B. Spiral- oder Schraubenfedern sein.According to
Gemäss Anspruch 5 kann es von Vorteil sein, wenn das Verankerungsteil des Verankerungsmittels umfänglich von einer Mischhülse umgeben ist, an der das oder die Mischelemente angeordnet sind. Durch diese Massnahme wird eine gleichmässige Verteilung der Mischwirkung des Antriebs auf die Komponenten des Mörtels erreicht. Von Vorteil kann es ebenfalls sein, wenn an dem bohrlochseitigen Ende des Verankerungsteils ein Verankerungsmittel angeordnet ist, mit dem das Verankerungsteil relativ drehfest im Bohrloch fixiert werden kann.According to
Auf der Oberfläche der Mischhülse oder in deren Wand können so z. B. rippen-, buckel-, noppen- oder schaufelförmige etc. Mischelemente angeordnet oder eingelassen sein. Die Mischelemente können z. B. aber auch als einfache Durchbrüche jeglicher Geometrie in der Wand der Mischhülse ausgebildet sein.On the surface of the mixing sleeve or in the wall can be such. B. ribbed, humpback, knobbed or paddle-shaped etc. mixing elements may be arranged or recessed. The mixing elements can z. B. but also be designed as simple breakthroughs of any geometry in the wall of the mixing sleeve.
