ABSTRACT:
An anchoring member is inserted into an anchoring hole in a support structure and has transverse dimensions smaller than those of the anchoring hole, and is supported with clearance in such anchoring hole by means of a cap member of ring-shaped configuration which surrounds the anchoring member at the trailing end thereof and closes the open end of the clearance. The anchoring member is of a tubular configuration and is closed at its leading end, an aperture communicating the interior of the anchoring member with the clearance. A body of hardenable material is introduced into the clearance through the aperture and by means of a shielding arrangement accommodated in the interior of the tubular anchoring member and communicating with the aperture. At least a portion of the ring-shaped cap member is at least translucent so that the introduction of the hardenable material into the clearance can be monitored therethrough. A depression, preferably an annular groove, is visible through the translucent portion and has such dimensions that, due to its viscosity, the hardenable material will not be able to penetrate into the depression until after the pressure in the clearance has exceeded a value indicative of the completion of the clearance-filling process. A small-sized opening communicates the clearance with the exterior of the cap member and allows air to escape from the clearance during the clearance-filling operation, while preventing the hardenable material from escaping therethrough until the pressure of the hardenable material has reached a predetermined level.
