Abstract (en)
A tool simple in structure is provided for uniformly disposing an anchor wedge. The tool can dispose the segments of the wedge without staggering them circumferentially or axially relative to each other to grip a PC steel member, and can prevent nonuniform application of additional stress on the PC steel member. The tool comprises a tubular part 10 and protruding parts 20, which are formed on one end of the part 10. The tubular part 10 surrounds a PC steel member (PC steel strand 100). Each protruding part 20 is inserted into the space between two adjacent wedge segments, which grip the PC steel member, to dispose the segments circumferentially at regular intervals. By inserting each protruding part 20 into the space between two adjacent wedge segments, it is possible to dispose the segments circumferentially at regular intervals.
