The engaging member 30 is rotated with respect to the hooking member 31 to release the state in which the engagement between the engaging member 30 and the guide wire 17 is held under pressure. After the gondola main body 2 is lowered by a predetermined distance, the engaging member 30 is engaged with the guide wire 17 by the operation opposite to the above, thereby suppressing the gondola main body 2 from moving downward. Then, the outer wall surface 11a of the building 11 is cleaned, repaired, painted, and the like.

Even when the gondola main body 2 descends, a tension toward the gondola main body 2 is applied to the engaging member 30, and the gondola main body 2 is urged toward the outer wall surface 11a of the building 11 and expands and contracts. The members 20 and 24 keep the gondola main body 2 separated from the outer wall surface 11a by a predetermined distance, so that the gondola main body 2 can be stably lowered.

In this way, while the gondola body 2 is sequentially lowered, the outer wall surface 11a of the building 11, etc. is washed, repaired, painted, etc., as needed.

When the gondola main body 2 is lowered and the engaging member 30 is positioned in the vicinity of the mounting bracket 16 as shown in FIG. 5, one engaging member 30A is removed from the guide wire 17, and the one engaging member 30A is connected to the fitting 16 and the other as shown in FIG. is rotated so as to be positioned below the engaging member 30B. As a result, one engaging member 30A can climb over the mounting bracket 16. As shown in FIG. It should be noted that while the holding of the guide wire 17 and the engaging member 30A is released, the holding of the guide wire 17 by the engaging member 30B is maintained. After that, one engaging member 30A is engaged with the guide wire 17 .

Further, when the gondola main body 2 is lowered and the other engaging member 30B is positioned in the vicinity of the mounting bracket 16, the other engaging member 30B and the guide wire 17 are separated in the same manner as the one engaging member 30A. After releasing the clamping and holding with, the other engaging member 30B is removed from the guide wire 17, the other engaging member 30B is rotated downward about the universal joint 37, and the mounting bracket 16 and one of the It is engaged with the guide wire 17 located below the engaging member 30A. As a result, the other engaging member 30B can climb over the mounting bracket 16. As shown in FIG. While the other engaging member 30B and the guide wire 17 are released from the clamping force, the one engaging member 30A and the guide wire 17 maintain the clamping condition.

As described above, when the engagement state between one engaging member 30A (30B) and the guide wire 17 is released, the other engaging member 30B (30A) clamps and holds the guide wire 17. By maintaining the state, it is possible to suppress the gondola main body 2 from inadvertently moving downward.

In addition, a plurality of curing net mounting brackets 50 are attached to the outer wall surface 11a of the building 11 at appropriate intervals in the vertical direction, and a curing net guide wire 51 is inserted through the curing net mounting brackets 50 to prevent curing. Since a plurality of engaging fittings 55 provided on the side elevation curing net 53 are attached to the net guide wire 51, when the gondola main body 2 is lowered, the lower end of the gondola main body 2 moves downward as shown in FIG. The side elevating protection net 53 is folded and accumulated on the upper part of the protection net mounting bracket 50 located nearby.

For this reason, after removing the engaging metal fittings 55 of the side elevating curing net 53 from the curing net guide wire 51 as appropriate, attach them to the curing net guide wire 51 positioned below the curing net mounting bracket 50 . , the accumulated side elevating curing net 53 can be moved downward to eliminate the accumulated state.

As the gondola main body 2 is located in a lower floor than a high floor of the building 11, the amount of the side elevating curing net 53 accumulated above the mounting bracket 50 for the curing net increases. Therefore, by increasing the mutual vertical spacing of the mounting brackets 50 for the curing net attached to the outer wall surface 11a of the building 11 toward the lower part of the building 11, the mounting brackets 50 for the curing net can be accumulated on the upper part. The amount of the side elevating curing net 53 can be increased toward the lower side of the building 11, and the number of times of canceling the accumulated state can be reduced. In addition, even if the vertical interval of the curing net mounting bracket 50 is widened toward the lower side of the building 11, the lower side of the curing net guide wire 51 does not sway in the horizontal direction, and the splash of paint or the like does not occur. has little effect on scattering suppression.

If the protective net mounting bracket 50 is configured by a hook or the like so that the protective net guide wire 51 can be detached from the protective net mounting bracket 50 attached to the outer wall surface 11a, the protective net can be removed. Only by removing the guide wire 51 for the curing net from the mounting bracket 50, the engaging metal fitting 55 of the side elevation curing net 53 is moved along the guide wire 51 for the curing net from the position of the mounting bracket 50 for the curing net by its own weight. may also be moved downward to eliminate the accumulated state.

Further, as shown in FIG. 8, when there is no bay window portion 11b and the outer wall surface 11a facing the gondola main body portion 2 is a single plane, the lower constituent members 41a, 41b, The length in the front-rear direction (XX direction) of 41c is adjusted to be the same length. Since the lower scattering suppression member 41 can rotate in the vertical direction around the rotating shaft 44, the tip of the lower scattering suppression member 41 contacts the outer surface of the building 11 by its own weight, and the gap can be reduced. , the scattering of paint or the like below the lower scattering suppression member 41 can be suppressed.

Further, as shown in FIG. 9, when there is a bay window portion 11b and the outer surface of the building 11 has unevenness, the front-rear direction ( XX direction) so that there is almost no gap between the lower structure 41b and the bay window portion 11b. It should be noted that the lengths in the front-rear direction (XX direction) of the lower components 41a and 41c located on both sides of the bay window portion 11b may be adjusted.

As described above, when adjusting the length of the central lower component 41b of the lower scattering suppression member 41 in the front-rear direction (XX direction), The angle becomes substantially constant. Even if the distance between the gondola main body 2 and the outer wall surface 11a changes due to fine irregularities on the outside of the building 11 or the effect of wind, the lower scattering suppression member 41 rotates vertically around the rotation shaft 44. Since it can move, the tip part of the lower scattering suppression member 41 abuts on the outer surface of the building 11 by its own weight, and the gap can be reduced.

Further, as described above, when adjusting the length of the left and right lower constituents 41a and 41c in the lower scattering suppression member 41 in the front-rear direction (XX direction), the lower scattering suppression member 41 rotates. Since it can rotate vertically about the shaft 44, as shown in FIGS. 12 and 13, the lower scattering suppression member 41 can follow the presence or absence of the bay window portion 11b while changing the angle with respect to the gondola main body portion 2. In addition, even if the distance between the gondola main body 2 and the outer wall surface 11a changes due to fine irregularities on the outside of the building 11 or the effect of wind, etc., the tip of the lower scattering suppression member 41 is always kept outside the building 11. The gap can be reduced by contacting the side surface.

Further, as shown in FIG. 10, when there is no bay window portion 11b and the outer wall surface 11c facing the gondola main body portion 2 is a single plane, the hairs used for the upper constituents 46a to 46h in the upper scattering suppression member 45 The lengths of the shaped members 47 in the front-rear direction (XX direction) are all substantially the same. As a result, the upper scattering suppressing member 45 can rotate vertically around the rotating shaft 48, so that the tip of the upper scattering suppressing member 45 can be brought into contact with the outer surface of the building 11 by its own weight. Scattering of paint or the like below the scattering suppression member 45 can be suppressed. Further, since the upper scattering suppressing member 45 is composed of a large number of hair-like members 47, it can follow fine irregularities and the like, so that the lower scattering suppressing member 41 can prevent downward scattering of the paint or the like. more controllable.

Further, as shown in FIG. 11, when the outer surface of the building 11 has irregularities such as the bay window portion 11b, as shown in FIG. The hair-like member 47 is replaced with a hair-like member 47 having a length such that the tip thereof contacts the bay window portion 11b. The hair-like members 47 having different lengths in the front-rear direction (XX direction) are attached to the upper structures 46a, 46b, 46g, and 46h located on both sides of the bay window portion 11b. good too.

As described above, when replacing the hair-like members 47 used in the front-rear direction (XX direction) of the central upper constituents 46c to 46f in the upper scattering suppression member 45, the gondola main body 2 of the upper scattering suppression member 45 becomes substantially constant. Even when the distance between the gondola main body 2 and the outer wall surface 11a changes due to fine unevenness on the outside of the building 11 or the influence of wind, the upper scattering suppression member 45 rotates vertically around the rotation shaft 48. Therefore, the tip of the upper scattering suppression member 45 can be brought into contact with the outer surface of the building 11 by its own weight.

Further, as described above, when the hair-like members 47 used for the upper components 46a, 46b, 46g, and 46h are replaced, the upper scattering suppressing member 45 can rotate vertically about the rotation shaft. , As shown in FIG. 13, while changing the angle of the upper scattering suppression member 45 with respect to the gondola main body 2, it is possible to follow according to the presence or absence of the bay window 11b, and the fine unevenness on the outside of the building 11, the influence of the wind, etc. Therefore, even when the distance between the gondola main body 2 and the outer wall surface 11a changes, the tip of the upper scattering suppression member 45 can always be brought into contact with the outer surface of the building 11 .

Except for the upper part of the gondola main body 2, it is surrounded by the outer wall surface 11a, the side elevating curing nets 53, 53, the rear elevating curing net 56, and the lower curing member 57, so that the scattering of paint etc. to the outside can be suppressed. .

As shown in FIG. 15, the circumferential direction of the gondola main body 2 is covered with side elevating curing nets 53, 53 and a rear elevating curing net 56 in a U-shape. 56 is below the lower end of the gondola body 2 and extends to the lower end of the building 11, so that the bay window 11b and the curing nets 53, 56 do not interfere with each other. can go up and down with

Splashing of paint or the like downward from the gondola body 2 is triple-suppressed by the lower scattering suppressing member 41 , the upper scattering suppressing member 45 , and the lower curing member 57 .
