In doing so, the tension member 10 and the wedge body (not shown) must be separated. To implement this, a rotational force and an external force are applied to the tension member 10, and the tow body (not shown) and the wedge body (not shown) are screwed. As they are coupled and moved, a separation space (not shown) is formed between the wedge body (not shown) and the coupled tension member 10, and by applying an external force again, the tension member 10 is easily installed on the ground or the building 60 can be withdrawn.

Referring to FIG. 6, to explain this in more detail, FIG. 6(a) shows that the gripping part 20 and the tension member 10 of the tension member removing device 1 are not coupled, and the tension member 10 is not connected to the ground or the building ( 60) is shown, and FIG. 6(b) is, after the tension member removing device 1 and the tension member 10 are coupled by the gripping part 20, they are fixed by the fastening member 22 This shows that the tension member removing device 1 applies an external force and a rotational force to the tension member 10 .

6( a ) shows the first time that the holding part 20 and the tension member 10 of the tension member removing device 1 are not coupled, and the tension member 10 is exposed to the outside of the ground or the building 60 . state is indicated.

In the initial state, as shown in FIG. 6(b) , the tension member 10 is inserted into the first hollow S1 of the gripping body 21 of the tension member removing device 1 to be fastened. The position may be fixed at a predetermined position by the member 22 .

Here, in order to separate the tension member 10 and the wedge body (not shown), the tension member 10 receives an external force from the external device 50 connected to the connection part 40 from the gripping part 20 . It is applied in the direction of the ground or the building 60 , and rotational force by the driving unit 30 may be applied.

Therefore, by the external force and the rotational force, the wedge body (not shown) is screwed with the traction body (not shown) and moved while the wedge body (not shown) is spaced apart between the tension member 10 coupled to the wedge body (not shown). U.S. city) may be formed.

At this time, the tension member 10 receives the external force by the external device 50 from the ground or the building 60 in the direction of the gripping part 20, and through the separation space (not shown), FIG. 6(c) As shown in , it can be easily withdrawn.

In this case, the tension member 10 is easily drawn out by the tension member removing device 1 instead of using an external force of the operator.
