Abstract

Anker, insbesondere Gebirgsanker, mit einem Zugglied (3), das mit einer Mehrzahl einzelner Einzelzugglieder (5), insbesondere aus Stahl, aufgebaut ist, einer Injektonsleitung (15), zumindest zum Bohrlochgrund, für erhärtendes Material, z. B. Zementmörtel, reaktive Kunststoffmischung, einer das Zugglied (3) umgebenden äußeren Umhüllung (10), mit einer Außenfläche, die einen erhöhten Widerstand gegen Verschiebung in Längsrichtung des Zuggliedes, insbesondere einen wellen- oder mäanderförmigen Längsschnitt, z. B. von einem auf der äußeren Umhüllung geformten Rundgewinde, aufweist und gegebenenfalls einem am Gebirge od. dgl. im oberen Kopfbereich des Ankers vorgesehenen Ankerkopf, und wobei am bohrlochgrundseitigen Ende der äußeren Umhüllung (10) das Zugglied (3) an dieser angreifbar ist, und wobei das Zugglied (3) am bohrlochgrundseitigen Ende einen angeformten Endteil (9) trägt, der an der äußeren Umhüllung (10), insbesondere am Stirnende derselben, abstützbar ist und daß der Endteil (9) mit der äußeren Umhüllung (10), insbesondere über ein gummielastisches Hüllstück (11, 13), fluiddicht verbunden ist.Anchors, in particular rock anchors, with a tension member (3), the with a plurality of individual single tension members (5), in particular made of steel, an injection line (15), at least to the bottom of the borehole, for hardening material, e.g. B. cement mortar, reactive plastic mixture, one surrounding the tension member (3) outer wrapper (10), with an outer surface that is raised Resistance to longitudinal displacement of the Tension member, especially a wave or meandering Longitudinal section, e.g. B. from one on the outer wrapper shaped round thread, and possibly an am Mountains or the like provided in the upper head area of the anchor Anchor head, and being at the bottom of the borehole end of the outer Envelope (10) the tension member (3) is vulnerable to this, and the tension member (3) at the end of the borehole base integrally molded end part (9) on the outer casing (10), in particular at the end of the same, can be supported and that the End part (9) with the outer casing (10), in particular via a rubber-elastic sleeve (11, 13), fluid-tight connection.
