DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, the present invention will be described with reference to the drawings. FIG. 1 is a front view showing an apparatus for dismantling a tower-like structure according to the present invention, FIG. 2 is a side view of FIG. 1, and FIG. 3 is a sectional view taken along line AA of FIG. Tower-like structure 1 such as a chimney to be dismantled
0, a mast 1 that is vertical in parallel with the tower structure 10
Build 2 on the ground. The two masts 12 are constructed on the opposite side of the tower-like structure 10 by 180 degrees. Mast 12
Is, for example, a prism having four columns and a height of 1.8 m.
A large number of mast blocks 14 are connected to each other.

[0008] A number of mast blocks 14 to mast 12
A mast height adjusting device 16 is known as a device for constructing a mast height. The mast height adjusting device 16 holds the mast 12 by holding means (not shown) and lifts the mast 12 upward.
The height of the mast 12 is increased by connecting and fixing a new mast block 14 to the mast block 14 at the lowermost end of the mast 2 by a conventionally known connecting means (not shown). In addition, the mast 12 is held by holding means (not shown), lifted upward, and the connecting means between the mast block 14 at the lowermost end of the mast 12 and the mast block 14 thereon is removed, so that the height of the mast 12 is reduced. It is to lower.

In the present invention, the heights of the two masts 12 are the same, and the heights thereof are slightly lower than the height of the tower-like structure 10. Then, on the two masts 12, the two masts 12 are connected, and a scaffold 18 that goes around the tower-like structure 10 is constructed and fixed. On this scaffold 18, a sturdy column 20 is arranged on the vertical line of each mast 12.

On the uppermost surface of the scaffold 18 (FIG. 3), a fixing base 22 is provided on each pillar 20.
The crusher 24 is fixed on the. The crusher 24 can be operated by a remote controller from a location remote from the crusher 24 by wire or wirelessly. The crusher 2
4 has an arm 26 and crushing means 28 attached to the free end of the arm 26. The crusher 24 may be any type of equipment as long as it breaks and dismantles the tower-like structure 16. As shown in FIG. 1, a jack base 30 as a fixing means is provided between the scaffold 18 and the outer wall of the tower-like structure 10.
And the tower-like structure 10 are fixed. In addition, mast 1
2 and the outer wall of the tower-like structure 10.
May be provided.

Next, the disassembly work will be described. Since the crusher 24 is directly supported by the mast 12 (column 20), the heavy crusher 24 can be positioned at the same height as the tower-like structure 16. Then, the upper part of the tower-like structure 10 is crushed by a predetermined height by the crusher 24 fixed to the scaffold 18. It is desirable that the crushing height is, for example, about the same as the height of one mast block 14. The crushed dismantled waste material is dropped into the internal space of the tower-like structure 16, and the dropped dismantled waste material is discharged from the inside of the tower-like structure 16 to the outside by a known method.

In this crushing operation, since the operator operates the crusher 24 from a position remote from the crusher 24 by a remote controller, the operator needs to directly crush the tower-like structure 10 with a conventional breaker. And the incidence of accidents during work can be greatly reduced. In addition, compared to the conventional work in which all of the dismantling work is performed manually, all of the work can be performed by mechanical work using the crusher 24, thereby greatly improving work efficiency and greatly reducing work time. Can be. Furthermore, since the worker does not directly crush the tower-like structure with the breaker, occupational diseases caused by the vibration of the breaker can be prevented. In this crushing work, if the height of the tower-like structure 10 is high, it is very difficult and costly to assemble a conventional high scaffold surrounding the periphery of the tower-like structure 10. In contrast, in the present invention, constructing the mast 12 and assembling the low-height scaffold 18 at the end of the mast 12 is simple and inexpensive. In addition, since the scaffold 18 and the tower-like structure 10 are fixed by the jack base 30,
Even if an excessive load such as a bending moment is applied to the crusher 24, the load does not shake the scaffold 18.

After the upper portion of the tower 10 is crushed by a predetermined height, the jack base 30 is operated to release the fixed state between the scaffold 18 and the tower 10. Then, one mast block 1 at the lower end from each of the two masts 12
4 is removed, and the height of the scaffold 18 and the crusher 24 is reduced by a predetermined height. Thereafter, the jack base 30 is operated to fix the scaffold 18 and the tower-like structure 10, and the upper part of the tower-like structure 10 is crushed to a predetermined height by the crusher 24 in the same manner as described above. As described above, every time the crusher 24 crushes the predetermined height of the upper part of the tower-like structure 10, if the mast 12 is lowered, only the crusher 24 replaces human power and the high tower-like structure is used. 10 can be dismantled.

Although two masts 12 are used in the embodiment shown in FIG. 1, one mast may be used. Next, an embodiment using one mast will be described with reference to FIGS. 4 to 6, the same reference numerals as those in FIGS. 1 to 3 indicate the same members. As shown in FIG. 4, the number of masts 12 is one, and a scaffold 32 that goes around the tower-like structure 10 around the one mast 12 is fixed. In this scaffold 32, a sturdy pillar 20 is arranged on the same vertical line as the mast 12. On the uppermost surface of the scaffold 18 (FIG. 5), a fixing table 22 is provided on the column 20, and the crusher 24 is fixed on the fixing table 22.

As shown in FIG. 4, the lower frame 34 constituting the lower portion of the scaffold 32 has two extended portions 36 extending from the mast 12 in the direction opposite to the tower-like structure 10.
(FIGS. 4 and 6). These two extensions 3
6 is located on the opposite side with respect to the position of the mast 12, as shown in FIG. Weights 38 are fixed to the free ends of the two extended portions 36. That is, the scaffold 32 and the two weights 3
The center of gravity with 8 is set on the vertical line of the mast 12. As shown in FIGS. 4 and 6, a jack base 30 is provided between the scaffold 32 and the outer surface of the tower-like structure 10, and the scaffold 32 and the tower-like structure 10 are fixed by the jack base 30. Also, as shown in FIG.
A jack base 30 may be provided between the base 2 and the tower-like structure 10.

The dismantling operation when one mast 12 is used is the same as that when two masts 12 are used.
The description is omitted. Tower-shaped structure 10 with a large diameter or width
It is more preferable to use two masts 12. However, by using one mast 12 for the tower-like structure 10 having a small diameter or width, the operation time and operation cost can be further reduced. In the above embodiment, the case where the number of the masts 12 is one and the case where the number of the masts 12 is two have been described, but three or more masts 12 may be used.

[0017]

As described above, according to the method for dismantling a tower-like structure according to the present invention, a mast is constructed at substantially the same height as the tower-like structure, and a crusher is directly supported on the mast. Therefore, the upper part of the tower-like structure can be crushed by the crusher. Therefore, since the worker can perform the crushing operation of the tower-like structure by the crusher by operating the remote controller, the incidence of accidents during the work can be significantly reduced. Further, as compared with the conventional work in which all of the disassembly work is performed manually, all of the work can be performed as mechanical work, work efficiency can be greatly improved, and work time can be significantly reduced. Furthermore, since the worker does not directly crush the tower-like structure with the breaker, occupational diseases caused by the vibration of the breaker can be prevented. Moreover, by constructing a mast and assembling a low-height scaffold at the end of the mast, the working time and cost can be significantly reduced as compared to a conventional tall scaffold. . Furthermore, when crushing the tower-like structure by the crusher, the scaffold and the tower-like structure are fixed by the jack base, which prevents the scaffold from wobbling and hinders the operation of the crusher. There is no.
