Description
Gegenstand der Hauptpatentanmeldung B 52 916 VIa/5 c ist ein Verfahren zum Befestigen von Ankerstangen beim Ankerausbau von Grubenräumen od. dgl. in ihren Bohrlöchern über einen Kunststoffkörper, der aus einem kalt härtbaren Kunststoffmaterial gebildet ist.The subject of the main patent application B 52 916 VIa / 5 c is a method for attaching Anchor rods in the anchor removal of pit spaces or the like in their boreholes via a plastic body, which is formed from a cold-curable plastic material.
Gemäß dem grundsätzlichen Merkmal der Hauptpatentanmeldung werden die durch ihre Mischung miteinander das erhärtende Kunststoffmaterial ergebenden Komponenten in voneinander getrennten Abteilen der Patrone in das Bohrlochtiefste eingebracht und dort nach Zerstören der Patrone und Drehen der Ankerstange gemischt.In accordance with the basic feature of the main patent application, the with each other the hardening plastic material resulting components in separate from each other Dividing the cartridge into the deepest borehole and there after destroying the cartridge and Rotating the anchor rod mixed.
Dieses Mischen erfolgt gemäß der vorzugsweisen Ausführungsform des Verfahrens nach der Hauptpatentanmeldung durch Eindrehen der in ihrem Endbereich als Mischschnecke ausgebildeten, d. h. mit entsprechendem Gewinde versehenen Ankerstange in die hierdurch zerstörte, in voneinander getrennten Abteilen die Komponenten enthaltende Patrone.This mixing takes place according to the preferred embodiment of the method according to the main patent application by screwing in the end area designed as a mixing screw, d. H. with corresponding thread provided anchor rod into the thereby destroyed, separated from each other Divide the cartridge containing the components.
Durch die Erfindung wird ein für die Durchführung des vorstehend gekennzeichneten Verfahrens besonders geeigneter Anker geschaffen, der es vermöge seiner neuartigen Ausbildung ermöglicht, das Verfahren nach der Hauptpatentanmeldung in der jeweils technisch vorteilhaftesten Weise durchzuführen, insbesondere den zwischen dem Ankerkopf und der Bohrlochwandung verbleibenden Raum unabhängig vom Bohrlochdurchmesser so zu bemessen, daß er zuverlässig von dem Patroneninhalt bzw. der aus diesem hergestellten Mischung der Komponenten ausgefüllt wird und gegebenenfalls die Verkleblänge des Ankers den wechselnden Gebirgsverhältnissen anzupassen. The invention makes one for carrying out the method characterized above special suitable anchor created, which by virtue of its novel design, enables the process to carry out according to the main patent application in the most technically advantageous manner, in particular the space remaining between the anchor head and the borehole wall independently to be dimensioned from the borehole diameter so that it is reliable from the cartridge contents or the this prepared mixture of components is filled and optionally the bonding length of the Ankers to adapt to the changing mountain conditions.
Das wird gemäß der Erfindung dadurch erreicht, daß der mit dem als Mischschnecke wirkenden Gewinde versehene Ankerkopf in bei Spreizankern bekannter Weise auswechselbar an einer genormten Ankerstange, die für alle vorkommenden Verhältnisse unverändert bleibt, angebracht, vorzugsweise über ein Gewinde mit Kupplung oder sonstige reversibel wirkende Verbindungselemente mit der Ankerstange verbunden ist.This is achieved according to the invention in that the thread acting as a mixing screw provided anchor head in a known manner with expansion anchors exchangeable on a standardized Anchor rod, which remains unchanged for all conditions that occur, attached, preferably via a Thread with coupling or other reversible connecting elements connected to the anchor rod is.
Ein in bekannter Weise den mit dem Kunststoff auszufüllenden Raum im Bohrlochtiefsten abdichtender Ring ist an dem auswechselbaren Ankerkopf angebracht.In a known manner, the space to be filled with the plastic in the deepest part of the borehole is sealed Ring is attached to the replaceable anchor head.
Der von der Ankerstange trennbare Kopfteil ist immer kürzer als die halbe Länge des gesamten Ankers und wird nach der Länge der vorgesehenen Klebfläche im Bohrlochtiefsten bemessen, die je nach den Gebirgsverhältnissen 30 bis 50 cm beträgt.The head section, which can be separated from the anchor rod, is always shorter than half the length of the entire length Anchor and is measured according to the length of the intended adhesive surface in the deepest part of the borehole, which depends on the mountain conditions is 30 to 50 cm.

Außer den oben erläuterten Vorteilen hinsichtlich der Anpassungsmöglichkeit des zu verklebenden Teils des Ankers an dem Umfang des Bohrlochdurchmessers und zweckentsprechende Bemessungsmöglichkeit der wirksamen Klebfläche wird durch diese Ausbildung des Ankers der auch bei an sich bekannten mit Spreizkopf versehenen mechanisch im Bohrloch befestigten Ankern mit von der Ankerstange trennbaren Kopf vorhandene Vorteil erzielt, daß, nachdem der Anker seine Aufgabe erfüllt hat, der genormte Teil der Ankerstange durch Herausschrauben derselben geraubt und dann erneut versetzt werden kann.In addition to the above-mentioned advantages in terms of adaptability of the to be bonded portion of the armature on the periphery of the borehole diameter and appropriate dimensioning possibility of effective adhesion area is through this formation of the anchor of the well in known per se with spreading head is provided mechanically in the drilled hole be strengthened anchors with the anchor rod separable head achieved advantage that, after the anchor has fulfilled its task, the standardized part of the anchor rod can be stolen by unscrewing the same and then relocated again.
Ein weiterer Vorteil der Erfindung besteht darin, daß der Kopf des Ankers aus einem anderen Material als der genormte Teil, der im allgemeinen aus Stahl besteht, z. B. aus einem gegebenenfalls mit Glasfasern armierten Kunststoff, wie z. B. Polyesterharz, Phenolharz od. dgl., hergestellt werden kann.Another advantage of the invention is that the head of the anchor is made of a different material as the standardized part, which is generally made of steel, e.g. B. from an optionally with glass fibers reinforced plastic, such as B. polyester resin, phenolic resin or the like. Can be produced.
Die Herstellung des Kopfes aus Kunststoff mit den die Schneckenpreßwirkung hervorrufenden Gewindegängen ist nach den Methoden der Kunststoff industrie wesentlich einfacher als die sonst notwendige Bearbeitung eines Stahlkörpers. Außerdem ergibt das Verkleben des Kunststoffkörpers mit dem Gebirge über die Kunstharzmischung eine weitere Verbesserung der Befestigung zwischen Ankerkopf und Gebirge.The production of the head from plastic with the threads causing the screw compression effect according to the methods of the plastics industry is much easier than the otherwise necessary processing a steel body. In addition, the gluing of the plastic body with the mountain results The synthetic resin mixture further improves the fastening between the anchor head and the rock.
Es ist auch möglich, die genormte Ankerstange selbst aus einem Kunstharzkörper von hinreichender Zugfestigkeit herzustellen.It is also possible to use the standardized anchor rod itself from a synthetic resin body of sufficient Establish tensile strength.

In der Abbildung ist ein Anker gemäß der Erfindung in Seitenansicht dargestellt. Er besteht aus einem Kopf 1 und der genormten Stange 2, die reversibel mit dem Ankerkopf über ein Gewinde 3 verbunden ist.In the figure, an anchor according to the invention is shown in side view. It consists of a head 1 and the standardized rod 2, which are reversibly connected to the anchor head via a thread 3 is.
Mit 4 ist das die Schneckenpreßwirkung hervorrufende gewinde des Ankerkopfes bezeichnet. Der mit Gewinde versehene Teil ist nach unten, d. h. nach der Bohrlochmündung zu, durch den in eine Nut 5 eingesetzten Dichtring 6 abgeschlossen.With 4 is the screw pressing effect causing thread of the anchor head. The threaded part is downward, i. H. after the borehole mouth closed by the sealing ring 6 inserted into a groove 5.
Das untere Ende der Ankerstange 2 ist mit Gewinde versehen, welches dem in der üblichen Weise mittels Bodenplatte und Mutter erfolgenden Verspannen des Ankers gegen das Gebirge dient. Die Ankerstange endet in einem Vierkant 8, an welchem die Vorrichtung zu ihrem Eindrehen und gegebenenfalls Herausschrauben angreift.The lower end of the anchor rod 2 is threaded, which in the usual way by means of the base plate and nut bracing of the anchor against the mountain is used. The anchor rod ends in a square 8 on which the device can be screwed in and if necessary Unscrew attacks.
