  Further, the diameter of the rod portion 5 is 10 mm, the diameter of the flange portion 16 is 34 mm, and the inner diameter of the hollow hole portion 13 in which the slit portion 20 of the fixing sleeve member 21 is provided and the blade portion 32 is formed is 13 mm. The fixing force adjusting member 12 is set to have a length of 20 mm, the diameter X of the maximum diameter portion and the diameter Y of the outer diameter portion of the fixing sleeve member 21 are both 19 mm, and the minimum diameter of the fixing force adjusting member 12 is set. The diameter Z of the part was set to 11 mm.

  Thereafter, the head 3 of the bolt member 2 is swung and rotated in a certain direction manually or using a mechanical device using appropriate swiveling means such as a spanner or a wrench. Generated by the second screw portion 8 of the fixing force adjusting member 12 and the cylindrical support portion 23 screwed together with the first screw portion 4 by the rotation of the first screw portion 4 provided in the portion. Due to the synergistic effect with the reaction force, the fixing force adjusting member 12 slides and moves on the rod portion 5 in the direction of the flange portion 16 of the fixing sleeve member 21 in the non-rotating state. 6 is deformed outward by the tapered portion 11 of the fixing force adjusting member 12, and as a result, the blade-like portion 32 is formed inside the hole portion 31, as shown in FIG. Part strongly pressed against the, it the securing sleeve member 21 by will be fixed to the hole 31.

FIG. 9 shows the detailed state at that time in correspondence with FIG.
In other words, in the present invention, the rod portion 5 of the bolt member 2 used as an anchor bolt includes the vicinity of the flange portion of the fixing sleeve member 21 and the internal hollow hole portion 9 of the fixing force adjusting member 12. The two are firmly fixed and held.

The above-described method of using or fixing the locking device 1 of the present invention can be applied not only to the road surface but also to the wall surface of a structure such as a building.
8 and FIG. 9 in the present invention, the locking device 1 shown in FIGS. 8 and 9 has a manhole portion arranged in a blindfolded manner with a concrete pavement layer or an asphalt pavement layer particularly during road construction. In this case, when opening the manhole by cutting and breaking the pavement material around the manhole, the concrete pavement or asphalt pavement is cut while turning a predetermined large road cutting cutter around the manhole in a circle. It can be used as the center of rotation of the cutter during processing.

  In such a usage mode, as shown in FIG. 10, a metal cross has four reinforcing foot portions 41 to 44, and a bolt made of a rod portion 5 forming the anchor portion at the center thereof.
