FRICTION BOLT AND EXPANSION ADAPTOR FOR SAID ANCHOR

摘要

A friction tube anchor has a tube (1) which can be expanded under the action of a pressurized medium and which is attached to a casing (6). The casing (6) is screwed into a section (13) of a casing-like sleeve (7) which is provided with a thread and is sealed by ring packing (11) relative to the inside of the section (13). The casing-like sleeve (7) has another section (14) which is provided with a thread and in which selectively either another expandable tube (1), or an adapter for feeding the pressurized medium for expanding the tube (1), or a fastening bolt, for example an eye bolt, can be screwed.
