摘要

In a structure of an anchor body (1), a deformed sheath made of steel (21) and having a tubular body whose peripheral wall presents an irregular configuration (26)is inserted in an excavated bore (2). At least one tension material (3) is inserted in the deformed sheath (21). A plurality of steel pipes (22) are covered on at least an end portion of an outer peripheral wall of the deformed sheath (21) or are inserted in at least an end portion of an inner peripheral wall of the deformed sheath (21), to reinforce the same. A hardener (5) is poured into the excavated bore (2) and a space (8) within the deformed sheath (21), to form a fastening section. A method of constructing the anchor body is also disclosed.
