環状の足場９を昇降自在に懸吊するようにした。The first figure shows an example in which the chimney protection curtain of the present invention is used for repairing a chimney, and numeral 1 in the figure indicates the chimney. At the top 1a of the chimney 1, a support 2 made of H steel materials assembled in a parallel cross shape is placed and fixed. An annular frame 5 is suspended such that it can be raised and lowered. A protective curtain 6 made of a disaster prevention mesh sheet is suspended from the annular frame 5. In this embodiment, a steel annular scaffold 9 is suspended by lobes 8 via a suspension fulcrum 7 consisting of a pulley provided on the support body 2 so as to be able to rise and fall freely.

護幕６で覆われる煙突部分を足場９上で補修作業する。To explain the assembly and disassembly of the chimney protection screen,
For example, first, the support body 2 is placed and fixed on the top 1a of the chimney 1, and the annular frame 5, which is vertically suspended by the lobes 4 via the suspension fulcrum 3, is lowered to the ground. Further, the annular scaffold 9, which is suspended by the lobes 8 via the suspension fulcrum 7 so as to be able to rise and fall freely, is left on the ground. Then, one sheet of protective curtain 6 is attached to the annular frame 5 on the ground, and the annular frame 5 is lifted by one sheet, and the annular scaffold 9 is lowered to the ground while covering the lower part of the chimney 1. Repair work is performed on the chimney above, and then one additional sheet of the protective curtain 6 is added, and then the annular frame 5 is lifted by one sheet of the protective curtain 6, and the annular scaffold 9 is attached to one of the protective curtains 6. The sheet is lifted up, and the chimney part covered by the protective curtain 6 is repaired on the scaffold 9.

足場９を取り外して防護幕の解体作業を終了する。The repair work of the chimney 1 is completed by repeating the addition and lifting of sheets of the protective screen 6 and the annular scaffolding 9 lifted by the amount of the protective screen 6 that has been lifted. When the repair work is completed, the entire chimney 1 will be covered by the protective curtain 6. After the work is completed, if the cover with the protective screen 6 is no longer necessary, lower the annular frame 5, remove the protective screen 6, and remove the support 2, the annular frame 5, and the annular scaffolding 9 from the chimney 1. The dismantling work of the protective curtain will be completed.

Alternatively, the annular scaffold 9 may be suspended from the annular frame 5 via, for example, lobes, and the annular frame 5 may be lifted.
Alternatively, when the annular scaffold 9 is lifted, the annular scaffold 9 is also lifted at the same time,
Alternatively, it may be hung.

防護幕の解体作業を終了する。Next, to explain how to assemble and dismantle the chimney protective curtain during chimney dismantling work using the chimney protective curtain, first, the support 2 formed in a cross-shaped structure is attached to the top 1a of the chimney 1. The annular frame 5, which is placed and fixed and suspended by a lobe 4 via a suspension fulcrum 3 so as to be able to rise and fall, is lowered to the ground. Further, the annular scaffold 9, which is suspended by the lobes 8 via the suspension fulcrum 7 so as to be able to rise and fall freely, is left on the ground. Then, one sheet of the protective curtain 6 is attached to the annular frame 5 on the ground in the same manner as in the embodiment described above, and the annular frame 5 is lifted one sheet at a time, so that the entire chimney 1 is covered with the protective curtain 6. Make it. Next, the circular scaffold 9
is lifted to a predetermined position of the chimney 1 to be dismantled, and the chimney part except the lower part of the support 2 which is placed and fixed on the top la of the chimney 1 using the annular scaffold 9 is dismantled from the top 1a. The chimney 1 is cut to a predetermined size to form four concave cut portions 10 in the chimney 1 as shown in FIGS. 2 and 3. Subsequently, as shown in the third figure, a moving device 11 for the support body 2, such as a hydraulic jack, is placed and fixed on the uncut top portion 1a of the chimney 1, and the moving device 11 is operated to move the top portion 1a of the chimney 1. The support 2, annular frame 5, annular scaffold 9, etc. placed on the holder are cut while being gently rotated in the side direction (arrow A) from the position shown by the solid line in Fig. 3 to the position shown by the imaginary line. After moving the support body 2 to the concave cut section 10 of the chimney 1, the support body 2 is placed and fixed in the concave cut section 10 of the chimney 1, and then the uncut portion of the chimney 1 is moved so that the top of the chimney 1 is almost flat throughout. Cut it so that it looks like this. Next, the annular scaffold 9 is lowered by a predetermined dimension, and the chimney 1 is cut by the predetermined dimension using the lowered annular scaffold 9. Such a support 2
The dismantling work of the chimney 1 is completed by repeating the movement and placement and fixation of the support body 2, and the annular scaffold 9 lowered each time the support body 2 is moved and placed and fixed. After the dismantling work is completed, the support 2, the annular frame 5, and the annular scaffold 9 are lowered to the ground.
The annular frame 5 and the annular scaffold 9 are removed from the support 2 to complete the dismantling work of the protective screen.
