On the upper part of the temporary scaffold 54, a lower curing member 57 is provided in the lateral direction, and by the lower curing member 57, at least the lower ends of the left and right side elevation curing nets 53 and 53 and the lower end of the rear elevation curing net 56 are formed. The part surrounded by the building 11 is covered. As the lower curing member 57, any member such as a curing sheet or a wooden board can be used as long as it is a member capable of suppressing the scattering of paint or the like. The lower curing member 57 may not be provided depending on the situation.

The upper ends of the side elevation curing net 53 and the rear elevation curing net 56 are adapted to move up and down following the elevation of the gondola body 2.

Next, a working method using the gondola body 2 will be described.

First, as shown in FIG. 15, the mounting brackets 16 and 50 are attached to the outer wall surface 11a of the building 11 by an arbitrary method, and the guide wire 17 is attached to the mounting bracket 16 to attach the curing net to the mounting bracket 50. Attach the guide wire 51 for the curing net.

Next, with the gondola body 2 located at the lowermost position, the upper ends of the left and right side elevation curing nets 53, 53 and the upper ends of the rear elevation curing nets 56 are attached to the gondola body 2, and then the gondola body 2 is attached. While raising the part 2 by the raising and lowering wire 15 and the driving part 14, the engaging metal fittings 55 of the side raising and lowering curing net 53 are sequentially attached from the lower end side to the curing wire guide wire 51 at appropriate intervals. ..

Next, with the gondola main body 2 in the highest position, the axial lengths of the elastic members 20 and 24 are adjusted with respect to the outer wall surface 11a of the building 11 excluding the bay window portion 11b. As shown in FIG. 12, the rotating member 22d of the expandable members 20 and 24 is brought into contact with the outer wall surface 11a, and the separation distance of the gondola body 2 from the outer wall surface 11a is adjusted to be a desired distance L1.

Further, the engagement member 30 is engaged with the guide wire 17 as shown in FIGS. 1 and 6, and the distance adjusting member 40 applies tension to the engagement member 30 to the gondola body 2 side. , The gondola body 2 is urged toward the guide wire 17, that is, the outer wall surface 11a side of the building 11.

In addition, while adjusting the length of the lower side scatter suppressing member 41 in the front-rear direction, the hair-like member 47 having a desired length is attached to the upper side scatter suppressing member 45, so that the lower side scatter suppressing member 41 and the upper side scatter suppressing member 45 are attached. The tip portion is brought into contact with the outer wall surface 11a.

Next, in the working space 60 of the gondola main body 2, as shown in FIG. 2, the worker 10 performs cleaning, repairing, painting, etc. of the outer wall surface 11a of the building 11 and the like.

Next, the engagement between the lock portion 31e of the hook member 31 of the engaging member 30 and the holding portion 32b of the retaining member 32 is released as shown in FIG. 7, and the retaining member 32 is rotated about the rotating shaft 31c. By rotating the hook member 31 to release the engagement between the engagement member 30 and the guide wire 17 held under pressure, the hook portion 31a is hooked on the guide wire 17 and is driven by the drive unit 14. After lowering the gondola main body 2 by a predetermined distance, the engaging member 30 and the guide wire 17 are engaged with each other by an operation opposite to the above, and the gondola main body 2 is prevented from moving downward. Then, the outer wall surface 11a of the building 11 is cleaned, repaired, and painted.

Even when the gondola main body 2 descends, tension is applied to the engagement member 30 toward the gondola main body 2 side, 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 maintain a predetermined distance between the gondola main body 2 and the outer wall surface 11a, so that the gondola main body 2 can be stably lowered.

In this way, cleaning, repairing, painting, and the like of the outer wall surface 11a of the building 11 are performed as needed while sequentially lowering the gondola body 2.

When the gondola main body 2 is lowered, as shown in FIG. 4, when the engaging member 30 is located in the vicinity of the fitting 16, the one engaging member 30A located above and the guide wire 17 are positioned. After releasing the holding pressure between the two, the one engaging member 30A is removed from the guide wire 17, and one engaging member 30A is attached to the fitting 16 and the other with the universal joint 37 as the center, as shown in FIG. The engaging member 30B is rotated so as to be positioned below the engaging member 30B. As a result, the one engagement member 30A can ride over the mounting member 16. It should be noted that while the holding pressure between the one engagement member 30A and the guide wire 17 is released, the other engagement member 30B maintains the state where the guide wire 17 is held under the pressure. After that, the one engagement member 30A is engaged with the guide wire 17.

Further, when the gondola main body 2 is lowered and the other engagement member 30B is located in the vicinity of the attachment fitting 16, the other engagement member 30B and the guide wire 17 are treated like the one engagement member 30A. After releasing the holding pressure of the other, the other engaging member 30B is removed from the guide wire 17, and the other engaging member 30B is rotated around the universal joint 37 in the downward direction, and the fitting 16 and one of the The guide wire 17 positioned below the engaging member 30A is engaged. As a result, the other engaging member 30B can ride over the mounting member 16. While the holding pressure between the other engaging member 30B and the guide wire 17 is released, the one engaging member 30A and the guide wire 17 maintain the holding pressure.

As described above, while the engagement state between the one engagement member 30A (30B) and the guide wire 17 is released, the other engagement member 30B (30A) holds the guide wire 17 under pressure. By maintaining the state, it is possible to prevent the gondola main body 2 from being inadvertently moved downward.

Further, 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 for curing. Since the plurality of engaging fittings 55 provided on the side elevation curing net 53 are attached to the net guide wire 51, when the gondola body 2 is lowered, as shown in FIG. The side elevating and lowering curing net 53 is folded and accumulated on the upper part of the curing net mounting bracket 50 located nearby.

Therefore, after appropriately removing the engaging metal fitting 55 of the side elevation curing net 53 from the curing net guide wire 51, the engaging metal fitting 55 is attached to the curing net guide wire 51 located below the curing net mounting metal fitting 50. The accumulated side elevation curing net 53 can be moved downward to eliminate the accumulated state.

As the gondola main body 2 is located in a lower level than the high level of the building 11, the amount of the side elevating and lowering curing net 53 accumulated on the upper portion of the curing net mounting bracket 50 increases. Therefore, by increasing the vertical interval between the curing net mounting brackets 50 attached to the outer wall surface 11a of the building 11 toward the lower part of the building 11, the curing net mounting brackets 50 can be integrated on the upper portion of the curing net mounting bracket 50. The amount of the side elevation curing net 53 can be increased toward the lower side of the building 11, and the number of times of eliminating the accumulation state can be reduced. Even if the vertical spacing of the mounting bracket 50 for the curing net is made wider toward the lower side of the building 11, the swaying movement of the lower side of the guide wire 51 for the curing net in the left and right directions is small, and the splash of paint or the like is small. There is little effect on the dispersion control of

When the curing net mounting bracket 50 is configured by a hook or the like so that the curing net guide wire 51 can be removed from the predetermined curing net mounting bracket 50 attached to the outer wall surface 11a, the curing net can be removed. By simply removing the curing net guide wire 51 from the mounting bracket 50, the engagement bracket 55 of the side elevation curing net 53 is moved by its own weight from the position of the curing net mounting bracket 50 along the curing net guide wire 51. May be moved to the lower side to cancel the accumulation state.

Further, as shown in FIG. 8, in the case where there is no bay window 11b and the outer wall surface 11a that faces the gondola main body 2 is one flat surface, the lower side structural members 41a, 41b in the lower side scatter suppressing member 41, The lengths of 41c in the front-back direction (XX direction) are all adjusted to the same length. Since the lower scattering restraint member 41 can rotate in the vertical direction about the rotation shaft 44, the tip end portion of the lower scattering restraint member 41 contacts the outer side surface of the building 11 by its own weight, and the gap can be reduced. The paint and the like can be prevented from scattering below the lower scattering suppressing member 41.

Further, as shown in FIG. 9, when there is a bay window portion 11b and the outer surface of the building 11 is uneven, the front-back direction of the lower structural body 41b in the lower scattering restraint member 41 located in the bay window portion 11b ( The length in the X-X direction) is adjusted so that there is almost no gap between the lower structural body 41b and the window part 11b. In addition, you may make it adjust the length of the front-back direction (XX direction) of the lower side structures 41a and 41c located in the both sides of the window part 11b.

As described above, in the case of adjusting the length in the front-rear direction (XX direction) of the central lower configuration body 41b of the lower scattering restraint member 41, the lower scattering restraint member 41 with respect to the gondola main body 2 is adjusted. The angle is almost constant. Even when the distance between the gondola main body 2 and the outer wall surface 11a is changed due to the influence of wind or the like on the outer side of the building 11, the lower scattering suppressing member 41 rotates in the vertical direction about the rotation shaft 44. Since it can move, the tip end portion of the lower scattering suppressing member 41 contacts the outer surface of the building 11 by its own weight, and the gap can be reduced.

Further, as described above, when the lengths of the left and right lower constituents 41a and 41c in the lower scattering suppressing member 41 in the front-rear direction (XX direction) are adjusted, the lower scattering suppressing member 41 rotates. Since it can be rotated in the vertical direction about the shaft 44, as shown in FIGS. 12 and 13, it is possible to follow the presence or absence of the bay window portion 11b while changing the angle of the lower scattering restraint member 41 with respect to the gondola body portion 2. In addition, even when the distance between the gondola main body 2 and the outer wall surface 11a is changed due to the influence of wind or the like on the outer side of the building 11, the tip of the lower scattering restraint member 41 is always outside the building 11. The gap can be reduced by abutting on the side surface.

Further, as shown in FIG. 10, when there is no bay window portion 11b and the outer wall surface 11c that faces the gondola body portion 2 is one flat surface, the bristles used for the upper constituents 46a to 46h of the upper scattering suppressing member 45. The lengths of the member 47 in the front-rear direction (XX direction) are all substantially the same. As a result, the upper scattering suppressing member 45 can be rotated in the vertical direction about the rotation shaft 48, so that the tip end of the upper scattering suppressing member 45 can be brought into contact with the outer surface of the building 11 by its own weight. It is possible to prevent the paint and the like from being scattered below the scattering suppressing member 45. Further, since the upper side 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 coating material and the like are prevented from scattering downward than the lower side scattering suppressing member 41. Can be suppressed more.

Further, as shown in FIG. 11, when the outer surface of the building 11 has irregularities such as the window part 11b, as shown in FIG. 11, the attachment member 46 in the upper scattering restraint member 45 located in the window part 11b. With respect to the upper constituents 46c to 46f, the bristle member 47 is replaced with a member whose length is such that the tip of the bristle member 47 abuts the exit window portion 11b. In addition, with respect to the upper structural bodies 46a, 46b, 46g, 46h located on both sides of the bay window portion 11b, the bristle members 47 are replaced with those having different lengths in the front-rear direction (XX direction). Good.

As described above, when replacing the hairy member 47 used in the front-back direction (XX direction) of the central upper constituents 46c to 46f in the upper scattering suppressing member 45, the gondola main body 2 of the upper scattering suppressing member 45 is replaced. The angle with respect to is approximately constant. Even when the distance between the gondola main body 2 and the outer wall surface 11a is changed due to the influence of wind or the like on the outer side of the building 11, the upper scattering suppressing member 45 rotates about the rotation shaft 48 in the vertical direction. Therefore, the tip end of the upper scattering suppressing member 45 can be brought into contact with the outer side surface of the building 11 by its own weight.

In addition, as described above, when the bristles 47 used for the upper constituents 46a, 46b, 46g, 46h are replaced, the upper scattering restraint member 45 can rotate in the up-down direction about the rotation axis, and therefore, FIG. , As shown in FIG. 13, while changing the angle of the upper scattering restraint member 45 with respect to the gondola main body 2, it is possible to follow the presence or absence of the bay window portion 11b, and the fine irregularities on the outside of the building 11 and the influence of wind and the like. Thus, even when the distance between the gondola main body 2 and the outer wall surface 11a is changed, the tip end portion of the upper scattering suppressing member 45 can be always brought into contact with the outer surface of the building 11.

Other than above the gondola body 2, it is surrounded by the outer wall surface 11a, the side elevation curing nets 53, 53, the rear elevation 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 gondola body 2 is covered in a U shape with side elevation curing nets 53, 53 and a rear elevation curing net 56 to form a side elevation curing net 53, 53 and a rear elevation curing net. By extending 56 below the lower end of the gondola main body 2 to the lower end of the building 11, the main window 2 is protected by the main body 2 without interfering with the bay window 11b and the curing nets 53, 56. It can go up and down with.

The downward scattering of the paint or the like 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.

In this way, painting or the like is performed up to the lower end of the building 11.

The work gondola device 1 according to the first embodiment has the above-described structure and configuration, and thus exhibits the following actions and effects in addition to the above description.

The fittings 16 are attached to the outer wall surface 11a of the building 11 at appropriate intervals in the vertical direction, and the guide wire 17 is inserted into the insertion hole 16a of the fitting 16 so as to be stretched. Even if the combined engaging member 30 is pulled toward the gondola body 2 by the distance adjusting member 40, the guide wire 17 is less likely to bend and the position of the guide wire 17 is stable in all of the lower layers to the upper layers of the building 11. The gondola body 2 can be stably biased toward the building 11 side.

In addition, two engaging members 30A and 30B are provided on each of the left and right sides of the gondola main body 2, and the guide wire 17 is always attached to the engaging member 30A (30B) except when the gondola main body 2 is moved up and down. Since it is possible to maintain the state in which the pressure is held, it is possible to prevent the gondola main body 2 from being inadvertently moved downward.

Further, the distance adjusting member 40 urges the gondola main body 2 toward the outer wall surface 11a of the building 11 and causes the elastic members 20 and 24 to contact the rotating member 22d with the outer wall surface 11a, and the elastic member 20. , 24 are expanded and contracted to adjust the distance between the gondola body 2 and the outer wall surface 11a excluding the window 11b to be a predetermined distance L1. A substantially constant pressing force can be maintained against the wall surface 11a.

In addition, the elastic members 20 and 24 have a biasing portion 22c that biases the tip end of the elastic portion 22 toward the front side (the outer wall surface 11a side), so that the elastic members 20 and 24 are stretched and contracted to form the gondola main body portion. When the guide wire 17 is deflected due to small irregularities in the outer wall surface 11a, wind, or the like after the distance between the outer wall surface 11a and the outer wall surface 11a other than the second window portion 11b is adjusted to be the predetermined distance L1. Moreover, the biasing portion 22c can absorb the deviation, and the distance between the gondola body 2 and the outer wall surface 11a excluding the window portion 11b can be kept substantially constant.

Further, since the elastic members 20 and 24 are provided at the four corners of the gondola main body 2, the position of the gondola main body 2 with respect to the outer wall surface 11a can be stabilized.

Further, the tip portions of the elastic members 20 and 24 are urged toward the outer wall surface 11a by the urging portion 22c, and the turning member 22d is provided at the tip portion, so that the gondola main body 2 is agitated by the wind. In such a case, it is possible to reduce the risk that the gondola main body 2 damages the building 11.

The upper ends of the side elevation curing nets 53 and 53 and the upper ends of the rear elevation curing nets 56 are fixed to the upper end of the gondola main body 2, and the upper ends of the side elevation curing net 53 and the rear elevation curing net 56 are fixed.
