Abstract

The present invention provides an internal fixer for an anchor having a releasable tensioning steel wire. The internal fixer of the present invention includes a first outer body (10), which is provided with a tube coupling hole (11), a body seating hole (13) and a wedge receiving body support means; and a wedge receiving body (30), which is seated in the body seating hole (13) and has a conical wedge seating hole (31), into which separated wedge bodies (41) are seated. The internal fixer further includes a wedge unit (40), which is seated in the wedge seating hole (31) of the wedge receiving body (30) and comprises the three separated wedge bodies (41); and a second outer body (20), which supports and covers both the wedge receiving body (30), which is seated in the body seating hole (13), and the wedge unit (40), which is placed in the wedge seating hole (31).

Description

TECHNICAL FIELD[0001]The present invention relates, in general, to internal fixers for anchors having releasable tensioning steel wires and, more particularly, to an internal fixer for an anchor having a releasable tensioning steel wire in which, when the tensioning steel wire is tensioned, a wedge receiving body along with separated wedge bodies is moved in the direction in which the tensioning steel wire is tensioned, and is fastened, so that the space required for movement of a wedge unit when the tensile force is removed is ensured, and in which only the separated wedge bodies are moved backwards by repulsive force generated when the tensile force is removing from the tensioning steel wire in the fixed state of the wedge receiving body, or by both the force of striking the tensioning steel wire inwards and the restoring force of a spring, and they are separated in the diameter direction, so that the tensioning steel wire can be easily and reliably removed.BACKGROUND ART[0002]Gen...
