HIGH-STRENGTH ANCHOR HAVING MANY ANCHORING BLADES CAPABLE OF MAXIMIZING THE FIXING STRENGTH ON THE GROUND

摘要

PURPOSE: A high-strength anchor having many anchoring blades is provided to reduce the cost and period of construction by shortening the whole length of an anchor and the perforating length of a grouting hole by reinforcing anchor strength, and to prevent the trouble caused by invading the adjacent land. CONSTITUTION: The high-strength anchor having many anchoring blades contains: an anchor body(10) having a cylindrical base(11) and many anchoring blades(15) spread radially by a torsion spring; an anchorage(30) coupled to the base of the anchor body(10) and provided with many through holes for letting steel wires(50) pass through; a spacer member(20) installed on the same axle as the central shaft of the anchor body(10) to spread each anchoring blade(15) outward, provided with many steel wire holes(23) formed along the axial direction of the anchor body(10) and connected with the anchorage(30) by a spring; and an anchoring wedge(35) anchored to the through hole of the anchorage(30) to fix the steel wire.
