FRACTURED ZONE POSSIBLE AT TENSION EXPANDED GROUND PRESSURE TYPE ANCHOR

摘要

PURPOSE: An expanded ground pressure type anchor for enabling tensioning in a fractured zone is provided to reduce construction costs by reducing the length of the anchor. CONSTITUTION: An expanded ground pressure type anchor for enabling tensioning in a fractured zone comprises a body(10), an expanded body(40), a cap(50), and a hitting bar(60). The body has a fastening groove(11), in which an anchor body(20) is fastened, and an insertion groove, in which the expanded body is inserted. The expanded body is fastened to the front end of the body. The cap is fastened to the front end of the body and has a center insertion hole(51). The hitting bar has a backing plate(61) and an insertion protrusion(52) inserted into the insertion groove(43) of the expanded body.
