Description

[Detailed description of the invention] [Purpose of the invention] (Industrial application field) The present invention relates to a work scaffold used for construction work.

(Prior Art) Since the outer wall surface of a building is constantly exposed to the external environment, it is easily contaminated by the effects of wind, rain, heat, etc.

Therefore, it is necessary to regularly clean and repair the exterior wall surface, and when performing these tasks, scaffolding for repair work is erected around the outer periphery of the building.

As conventional general work scaffolding, main scaffolding, frame scaffolding, gondola scaffolding, etc. are known. This scaffolding or framework scaffolding is constructed from the ground to surround the entire building. In addition, gondola scaffolding suspends a gondola that serves as a work floor from the roof of a building, and moves it as the work area moves.

By the way, although the above-mentioned scaffolds and framework scaffolds have excellent workability, they require considerable effort and expense to assemble and dismantle, and a height of approximately 501 mm is considered to be the safety limit. Moreover, since it encloses the entire outer periphery of the building, it has the disadvantage that, especially in the case of renovation work on the exterior walls of an existing building, it blocks sunlight from entering each residential room, giving residents a significant sense of pressure.

On the other hand, gondola scaffolding is suitable for high-rise buildings whose height is difficult to accommodate with regular scaffolding or frame scaffolding, and it also has relatively little impact on residents.

However, this gondola scaffolding has the fate of having to move the gondola many times as the work area moves, and therefore is inferior to the above-mentioned main scaffolding, framework scaffolding, etc. in terms of workability. In addition, gondola scaffolding tends to sway due to the wind and has the disadvantage that it is inferior to regular scaffolding, frame scaffolding, etc. in terms of safety.

(Problems to be Solved by the Invention) As described above, conventional work scaffolds, especially work scaffolds of the type suspended from the roof of a building via cables such as wire robes, are different from main scaffolds and frame scaffolds. In comparison, the workability was inferior, and there was a problem in that the shaking caused by wind etc. caused workers to feel uneasy.

The present invention was made to solve such problems,
The aim is to provide a work scaffold that can expand the work area and reduce lateral sway caused by wind, etc. while taking advantage of the advantages of gondola scaffolding.

[Structure of the invention]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the work scaffold of the present invention has a plurality of projecting beams attached to the top of the building, and is capable of being raised and lowered from each projecting beam via cables. It is characterized in that the hanging scaffold is hung in such a manner that it extends over at least two adjacent sides of the peripheral wall of the building.

(Function) The working scaffold of the present invention has a suspended scaffold that can be raised and lowered from the top of a building and is suspended in such a manner that it spans at least two adjacent sides of the peripheral wall of the building. When suspended across two adjacent sides of a peripheral wall of a building, it is possible to suppress lateral sway due to wind, etc. in some directions to the extent that it does not pose a safety problem at all.

Furthermore, by increasing the number of sides of the building's surrounding wall that the hanging scaffold straddles, such as the 3rd and 4th sides of the building's surrounding wall, and eventually surrounding the entire perimeter of the building with the hanging scaffold, the sway of the scaffolding is reduced. can be suppressed in all directions to an extent that poses no safety problem. Moreover, the work area for each suspended scaffold movement position is expanded, and work efficiency is improved.

(Example) Embodiments of the present invention will be described below with reference to the drawings.

Fig. 1 is a sectional view for explaining the structure of a working scaffold according to an embodiment of the present invention, Fig. 2 is a perspective view showing the entire working scaffold of Fig. 1, and Fig. 3 is an elevational view of Fig. 2. It is a diagram.

As shown in these figures, the work scaffold of this embodiment is suspended from a plurality of support beams 10 attached so that their tips protrude from the wall surface of the building 1 on the roof of the building 1 via hanging wire lobes 20. A suspended scaffold 30 is hung in such a manner that it straddles two adjacent sides of the peripheral wall surface of the building 1.

Each of the above-mentioned support beams 10 is temporarily fixed to, for example, a rosette provided on the roof of the building 1 at approximately equal intervals. Two hanging wire lobes 20 are tied to each support beam 10, and the lower ends of each hanging wire lobes 20 are tied to the frame 31 of the hanging scaffold 30 via hoists 32 and 33, respectively. . In addition, all the hoisting machines 32.33 provided on the suspended scaffolding 30 are interlocked, and these hoisting machines 32.3
3 can be operated by remote control from the rooftop, the ground, or indoors. The hanging scaffold 30 is designed to move up and down along the wall surface of the building 1 while maintaining a generally horizontal state as a whole.

Further, this hanging scaffold 30 is surrounded by a frame 34 using metal vibrators or the like, including the ceiling part, except for the side of the building 1, and the outside of this frame 34 is covered with a curing net 35. This prevents the scaffolding from falling from the hanging scaffold 30 and allows offerings during rain or snowfall. Further, guide rollers 36 are attached to the pedestal 31 of the suspended scaffold 30 for smoothly raising and lowering the scaffold 30 along the wall surface of the building 1.

Now, the feature of the work scaffold of this embodiment is that, as mentioned above, the suspended scaffold 30 is suspended from the roof of the building 1 in such a manner that it straddles two adjacent sides of the peripheral wall of the building 1. It is in.

This makes it possible to suppress the horizontal shaking of the suspended scaffolding 30 due to wind or the like in some directions to the extent that it does not pose any safety problems.

Furthermore, hang scaffolding 3 on the 3rd and 4th sides of the surrounding wall surface.
By increasing the side of the wall that 0 straddles and finally surrounding the entire perimeter of the building 1 with the hanging scaffold 30, the hanging scaffold 30
It is possible to suppress the lateral shaking in all directions to the extent that it does not pose any safety problems. In addition, by configuring the suspended scaffolds 30 to be connected long horizontally in this way, the work area at one movement position of the suspended scaffolds 30 is expanded, and furthermore, the entire circumference of the building 1 is surrounded by the suspended scaffolds 30. This makes it possible to perform work on a floor-by-floor basis.

Although the suspended scaffolding 30 of the above-described embodiment is provided with only one level of work floor, it may be provided with multiple levels. Furthermore, in the present embodiment described above, the hoisting machines 32 and 33 for raising and lowering the suspended scaffolding 30 were provided on the side of the suspended scaffolding 30.
Of course, it may be provided on the support beam 10 side.

Furthermore, the lifting and lowering operations of the hanging scaffold 30 may be performed by a worker riding on the hanging scaffold 30.

[Effects of the Invention] As explained above, according to the work scaffold of the present invention, it is possible to expand the work area and reduce lateral sway due to wind and the like while taking advantage of the advantages of the gondola scaffold.
