Abstract:
The present invention provides a steel strand anchoring structure enabling safe dismantlement, the steel strand anchoring structure being installed on the end portion of a steel strand (100) of a concrete structure and comprising: an anchor member main body (200) of which one end is opened and the other end has formed thereon a stopping protrusion (210) having a center hole (230); a fixer (300) which has a hollow (310) formed therein and is installed on the stopping protrusion (210) by being inserted in the one end of the anchor member main body (200); a sleeve (400) which has a hollow (410) formed therein and of which one end is inserted in the hole (230) so as to be coupled to the other end of the hollow (310); a protective cap (500) which fixes the end portion of a steel strand (100) which has passed through the hollow (410) and the hollow (310) in order; a buffering material (600) which is an elastic material for impact absorption and has formed on the other end thereof an insertion hole (610) in which the protective cap (500) is inserted; and a cap (700) which is coupled to the one end of the anchor member main body (200) in a state where the buffering material (600) is inserted in the anchor member main body (200), wherein, even when the steel strand (100) is cut during the dismantlement of a concrete structure, the buffering material (600) absorbs the impact from the release of tensile force.
