Is a drive motor provided with the drive pulleys 2a and 2b, and is a motor for rotating the diamond wire 5. This diamond wire 5 has five diamond pulleys 3a, 3b, 3c, 3d, 3e,
Each of the pulleys is fixed to a pulley support pipe Y while being wound by two wire locking rollers 4a and 4b. Among these pulleys, the diamond pulley 3a is installed so as to be able to move up and down,
This is provided for lifting the diamond wire 5 upward.

[0010] The device of the present invention is a pulley sliding pipe R
The slide poles 6 and 6 are attached to the apparatus so that the apparatus main body is slidably moved left and right. This sliding is
By lifting the diamond pulley 3a, the diamond wiper 5 is pulled upward and simultaneously slid inward. That is, since the cut portions W of the concrete columns H are sequentially cut, it is necessary to pull the diamond wire 5 little by little.
7 is an anchor, 8 is a safety cover, and 9a and 9b are feed motors.

Next, a method of using the concrete member cutting apparatus according to the present invention will be described. First, as shown in FIG. 1, the main body of the apparatus of the present invention shown in FIG. 3 is disposed at a location of a concrete pillar H to be cut, and a diamond wire 5 is wound around the concrete pillar H. Next, when the drive motors 1a and 1b are operated (the operation means is not shown), the concrete columns H are sequentially cut (in a dotted line state) via the diamond wires 5. This cutting can be performed by sequentially lifting the diamond pulley 3a. By such an operation, the concrete pillar H can cut the cut concrete pillar like a concrete pillar cut portion G as shown in FIG. In addition, 10 is a diamond core.

[0012]

The main structure of the present invention is that in a method of cutting a concrete structure using a wire saw, a diamond wire is wound around members such as desired cut concrete pillars and walls and is linked to a drive motor. This is a method of cutting concrete members by a diamond wire saw that cuts members such as concrete columns and walls by driving a diamond pulley attached to the diamond wire saw through a driving pulley.
