Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a method for raising and lowering a scaffolding stage, and in particular,
The present invention relates to a method for raising and lowering a scaffolding stage that can be positioned at any position on the vertical surface of a building or the wall surface of a structure such as the belly of a ship. .

[Conventional technology]

Scaffolding stages are installed horizontally along the wall of a structure at arbitrary positions and used as material storage areas, worker walkways, or work scaffolding, and are installed at appropriate height intervals on the wall of the structure. Although it is desirable to have multiple stages of scaffolding, installing multiple stages of scaffolding not only increases the number of temporary materials and is uneconomical, but also increases the cost of constructing the structure. There is.

Therefore, a scaffolding stage that can be fixed at a desired height position and transferred to another height position has been proposed, and as a method of raising and lowering the scaffolding stage, a winch mechanism equipped on the scaffolding stage is used to fix the scaffolding stage. A method has been proposed in which a wire used as a hanging member is wound up and raised and lowered.

However, when a small number of workers of one or two races perform short-term work on the wall surface of a structure at different heights, and the scaffolding stage is raised and lowered each time, the scaffolding stage is generally long. Considering that the materials are heavy and heavy, it is necessary to frequently make various arrangements to prevent materials from falling during transportation, and security control of the surrounding area is frequently required during transportation. , there are many extremely inconvenient points.

Therefore, in recent years, a single scaffolding stage has been fixed in a predetermined position for a relatively long period of time and used as a material storage area or a walkway for workers. Various desired operations will be carried out using gondolas, which serve as work scaffolds that can be moved up and down. The method of moving the gondola is to raise and lower the gondola by winding up a wire serving as a hanging member of the gondola using a winch mechanism installed in the gondola.

[Problem that the invention seeks to solve]

However, according to the above-mentioned proposal, a winch mechanism equipped on the scaffolding stage is used, especially when raising and lowering the scaffolding stage, as described above.

As the scaffolding stage is fixed in a fixed position for a relatively long period of time, equipping the scaffolding stage with a winch mechanism that is used only for raising and lowering the stage increases the weight of the scaffolding stage and reduces the material cost. Inconveniences may arise, such as reducing the allowable range of loading weight for workers and workers, reducing the effective space for walkways, etc., and causing problems such as the winch mechanism not operating properly if left unused for a long period of time. There is also the fear that inconveniences may arise.

Therefore, in view of the above-mentioned circumstances, the present invention provides a new method for raising and lowering a scaffolding stage, which allows the scaffolding stage to be positioned at any position on the wall surface of a structure without equipping the scaffolding stage with a winch mechanism. The purpose is to

[Means for solving problems]

In order to solve the above-mentioned problems, the configuration of the present invention is such that when a scaffolding stage extending horizontally along the wall of a structure is raised and lowered, the scaffolding stage is connected to a gondola movably disposed above the scaffolding stage. It moves in the vertical direction, and when the scaffolding stage is fixed, it is suspended by an appropriate hanging member whose upper end is connected to the top end of the structure, and is separated from the gondola. This is what I did.

〔Example〕

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The method according to the present invention will be explained below based on the best embodiment shown in the drawings.

Figure 1 is a perspective view showing a situation in which a scaffolding stage 1 is horizontally extended along an outer wall surface BK, which is a wall surface, of a building A, which is a construction, by the method of the present invention. ? Figure 2 is a longitudinal sectional view thereof.

And this? As shown in Figure 1 and Figure 2, the scaffolding stage 1 has connectors 5, 6 attached to the lower part of wires 3, 4 whose upper ends are fastened to a support arm 2 fixed to the top C of the building A. It is connected and suspended. Further, above the scaffold stage 1, a gondola 7 is connected by a winch mechanism 10 to the lower part of a wire 9 whose upper end is fastened to another support arm 8 fixed to the top C of the building A. It is suspended.

The scaffolding stage 1 is installed horizontally along the width of the outer wall surface B of the building A by the wire 3.4 at an arbitrary height position, so that the upper surface of the scaffolding stage 1 is It can be used as a material storage area or a walkway for workers, and the bottom surface can be used as a security roof for people entering and exiting Building A or passing under scaffolding stage 1. That is.

Further, the gondola 7 is suspended from the top C of the building A by the wire 9 as described above, and operates the winch mechanism 10 equipped on the gondola 7 to wind up the wire 9. This provides a work scaffold that is movable vertically along the length of the exterior wall of building A, thereby allowing workers to enter the top surface and perform various tasks on exterior wall B. be.

It is sufficient that the support arm 2 is formed so as to suspend the scaffold stage 1 below and not settle in a predetermined position, but in this embodiment, the support arm 2 is As shown, the attachment for fixing the support arm 2 to the top end C of the building A consists of a section 11, and the arm section 12 projects horizontally from the section 11. The portion 11 is formed to be detachably attached to a desired position on the top end C of the building A, and the attachment is performed by attaching the one to the tip portion of the portion 11, that is, the base end portion of the arm portion 120. The wire 3 is fastened thereto, and the other wire 4 is fastened to the distal end portion of the arm portion 12.

As mentioned above, when attempting to raise and lower the scaffolding stage 1 suspended from the top C of the building A by the wires 3 and 4, first,
The gondola 7 is lowered to the top surface of the scaffold stage 1 or near the top surface. After the gondola 7 has descended to a desired height position, the gondola 7 is temporarily stopped moving up and down at that height position, and the scaffold stage 1 is connected to the gondola 7. The gondola 7 and the scaffolding stage 1 can be connected arbitrarily, but in this embodiment, the upper end is connected to the handrail part of the gondola 7 at 5k, as shown in the lower half of Figure 2. This is done by connecting the lower end of a hanging material 13 such as a wire or chain to an appropriate position on the scaffolding stage 1.

After connecting the lowered gondola 7 and the scaffolding stage 1 as described above, the scaffolding stage 1 and each wire 3.
4 is released, the scaffolding stage 1 is suspended from the gondola 7, and the winch mechanism 10 equipped on the gondola 7 is activated to suspend the gondola 7. The scaffolding stage 1 will be raised and lowered by winding the wire 90 held thereon.

If the scaffolding stage 1 is to be extended to a new height position, after confirming that the scaffolding stage 1 has reached the desired height position, The scaffolding stage 1 is connected to the hanging wires 3 and 4 using connectors 5 and 6, and the connection with the gondola 7 is released. As a result, the scaffolding stage 1 can be used as a material storage area or a worker's walkway at a new height. Further, the gondola 7 is separated from the scaffolding stage 1, and is able to move up and down independently and with its own blade, and is used as a work scaffold for various desired operations.

In addition, when the scaffolding stage 1 connected to the gondola 7 is to be removed from the outer wall surface B of the building A, the gondola 7 is lowered and the scaffolding stage 1 is placed on the ground surface etc. After confirming that, the descent of the gondola 7 is stopped, and the connection between the scaffolding stage 1 and the gondola 7 is released. As a result, the scaffolding stage 1 is removed from the outer wall surface B of the building A, and can be transported to another destination.

Further, the gondola 7 separated from the scaffold stage 1 is provided as a work scaffold for various operations on the outer wall surface B of the building A, if necessary.

As described above, the scaffolding stage 1 extended to the outer wall surface B of the building A is raised, lowered, and fixed. An embodiment of the scaffolding stage 1 that is most suitable for use will be briefly described below.

That is, as shown in Figure 4, the scaffolding stage 1 is
A sub-corridor 21 is attached to both ends of the corridor so that it can be moved in and out, and by moving the sub-corridor 21 in and out of the main corridor 20, the length of the entire corridor can be expanded or contracted. The main hallway 20 has a scaffold board 23 between a pair of dense members 22, and the sub-corridor 21 has a scaffold board 25 between a pair of dense members 24, and the dense member 24 is connected to the surgical member 22 of the main hallway 20. It is inserted into the body so that it can be freely moved in and out. Furthermore, a handrail 26 and a handrail 27 are attached to the main corridor 20 and the sub-corridor 21, respectively. The handrail 26 is configured to form a frame by integrally connecting a cross member 29 to a column 28 whose lower end is attached to the dense member 22 in a foldable manner. It is inserted in a socket 30 fixed to 22. Then, when the handrail 26 is lifted upward so as to raise the lower end of the column 28, it becomes possible to fold it in the lateral direction of the scaffolding stage 1 so as to place it on the scaffolding board 23 of the main hallway 200. A lower end of the support column 28 and a socket 30 are formed at the bottom. In addition, the handrail 27 of the sub-corridor 21 has its lower end connected to the girder member 2.
A support 31 attached to the frame member 4 so that it can be folded freely holds an extensible horizontal member 32 such as a chain, and the lower end of the support 31 is inserted into a socket 33 fixed to the girder member 24. . The cross member 32 has one end locked to the support 31 and the other end connected to the end of the handrail 26 of the main hallway 20.

Therefore, if the sub-corridor 21 is entered or exited from the end of the main corridor 20, the entire length of the corridor can be expanded or contracted, and if the handrail 26 is pulled up, it can be stacked on the scaffolding board 23 of the main corridor 20. It can be folded. In addition, the handrail 27 in the sub-corridor 21 can be folded, so the scaffolding stage 1 has a compact structure, which is convenient for handling such as transportation, and is convenient for construction. External wall surface B of object A
When extending to the main corridor 2, the sub-corridor 21 is separated from the main corridor 2 so as not to create a gap with other adjacent scaffolding stages 1.
It can be extended from 0, and has the effect of improving safety as a walkway for workers and preventing dangers such as materials placed on the top surface from falling downward.

〔Effect of the invention〕

As described above, according to the present invention, the scaffolding stage can be raised, lowered, and fixed without requiring equipment such as a winch, so that when the scaffolding stage is used as a material storage area or a worker's walkway, the overall weight of the scaffolding stage can be reduced. It is possible to obtain a scaffolding stage that does not have the inconvenience of increasing the allowable range of the live load, or reducing the effective space for storage space or walkway space.

Furthermore, if the scaffolding stage is formed to be extendable and foldable, it can be raised and lowered without causing any obstruction to the neighboring scaffolding stages, and It also has the advantage of covering gaps and the like that occur between stages and other scaffolding stages, thereby preventing workers, materials, etc. from falling downward.
