摘要： The invention relates to an expansion anchor (10) in the form of a frame anchor which can be expanded by the insertion of a conical expansion body (14), using an adjusting screw. If a borehole becomes enlarged, in order to achieve further expansion, an anchor sleeve (12) is configured for the expansion anchor (10), comprising a peripheral groove as an extensible point and/or predetermined separation point (18) which allows an axial extension and/or a separation of the anchor sleeve (12). A rear section of the anchor sleeve (12), together with the adjusting screw therein and the expansion body (14) can be axially displaced in relation to a front section of the anchor sleeve (12), using the extensible and/or predetermined separation point (18). The expansion body (14) is thereby drawn deeper into the front section of the anchor sleeve (12), further expanding said anchor sleeve.

摘要： The invention relates to an expansion bolt (10) for anchoring in a cylindrical borehole (40). According to the invention, the expansion bolt (10) is configured with a tubular bolt base part (12) to which a hollow conical expansion section (22) is moulded by forming. An expansion sleeve (14) that is bent from a sheet is placed on said expansion section. The expansion bolt (10) is anchored in the borehole (40) by the axial displacement of the expansion sleeve (14) on the expansion section (22). The expansion bolt (10) expands further if the borehole (40) expands, for example as a result of cracking.
