ABSTRACT:
An anchor sleeve for a composite anchor is threaded in its inside surface and is anchored by at least one of an organic and inorganic mortar in a borehole formed in a concrete tie for rails or in a similar receiving material. The inside threaded sleeve (2) forms a load engagement means for an attachment member and is located in a trailing end region of the sleeve. The sleeve has two concentrically and consecutively arranged sealing elements (7, 9) at an opposite leading end of the sleeve and the sealing elements close off the leading end of the sleeve in a liquid-type manner. The sealing elements (7, 9) can be consecutively displaced out of sealing engagement at the leading end of the sleeve (2). In addition, a method for corrosion resistant anchorages employs the anchor sleeve.
