PURPOSE:To provide a cutting device for cutting a reinforced concrete structure by wire sawing whose setting work is facilitated. CONSTITUTION:A rod 7 extending sideways is fixed to a mounting base 1 fixed to the side surface of a reinforced concrete structure 3, a rack 8 is laid along the rod 7, and an arm 13 is orthogonally fixed thereto. A self-traveling base 9 rotatably installed to the rod 7 has a pinion rotated by a motor 11 and geared with the rack 8, and a cable driving pulley 12. A pair of guide pulleys 14 are mounted on one side of the arm 13 with the rod 7 between, and one guide pulley 14 on the other side. A cutting cable 15 is laid over the pair of guide pulleys 14 in S-shape. Thus, cutting work can be performed only by laying the cutting cable 15 after mounting the mounting base 1 on the reinforced concrete structure 3, and regulation of the direction and position of each pulley for centering is not required. |
