FIELD: mechanical engineering.
SUBSTANCE: proposed expansion anchor contains main member driven into drilled hole and provided with expansion section expanding in direction of anchor driving. Main member of anchor is provided with through hole. Expansion anchor contains also expansion bushing fitted for sliding along axis on expansion section and expanding in process of displacement. Expansion bushing encloses expansion section from front side in direction of driving in of expansion anchor and overlaps through hole in main member. Displacement of expansion bushing is done by impact loading along axis.
EFFECT: low cost, simple design, ease of manufacture, provision of residual property for further expansion.
