DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a scaffolding device used as a work floor for work at heights, for example, for high-rise buildings and glass window cleaning.

[0002]

2. Description of the Related Art In recent years, a scaffolding device of this type has been constructed in which a building and a fabric are formed as a frame unit along a wall surface of a building by using a steel pipe and a fastener, and are assembled by being braced around the building unit. It has been known.

[0003]

However, in the case of the conventional scaffolding device, a strong scaffold must be framed for safety before construction of the building, and the scaffolding device must be disassembled upon completion of the construction. In addition, the labor has become enormous, and it can be said that such work is wasteful, so that there is an inconvenience that the working cost has to be increased.

[0004]

A main frame member connected to the main frame member, a lifting member provided on the main frame member so as to be movable up and down, and a lifting
A rack provided on the main frame member in a vertical direction,
Attached to the main shaft of the elevating motor, meshable with the rack
Noh pinion, respectively on the left and right sides of the elevating member projecting from the water <br/> horizontal direction, fixed scaffold and extendable telescopic scaffold
Member made of a material , and a handrail erected on the member
In scaffolding apparatus characterized by being configured a wood.

[0005]

[Function] A grounding underframe is carried into a construction site and set in a predetermined position, and the frame members are stacked and connected to form a main frame member, which is then lifted.
The elevating member is moved up and down along the main frame member through the rack and the pinion by the drive of the elevating motor to arrange the scaffold member at an appropriate height, and project from the left and right sides of the elevating member respectively.
Extend and retract the scaffolding material of the installed scaffold member, set it to an appropriate length, and move the handrail material on the scaffolding member while raising and lowering the elevating member.
You will be working at heights while using it.

[0006]

1 to 6 show an embodiment of the present invention. Reference numeral 1 denotes a grounding frame, which is provided with a moving wheel 2 and a trigger 3.

Reference numeral 4 denotes a main frame member. In FIG.
It is composed of three frame members 5 each having a rectangular frame shape having a frame structure with a height of 3 m. The lowermost frame member 5 is attached to the center of the grounding frame 4, and usually one frame member 5 is mounted on the frame member 5. Are stacked to form a 6 m main frame member 4, or as shown in FIG. 1, two frame members 5 are stacked and bolted together to form a 9 m main frame member 4.
May be formed.

Reference numeral 6 denotes an elevating member, which in this case is formed in a rectangular frame shape having a frame structure so as to surround the main frame member 4, and the elevating member 6 can be raised and lowered along the main frame member 4 by a guide roll 7. The two lifting motors 8 are attached to the vertical position of the lifting member 6, the pinion 9 is mounted on the main shaft of the lifting motor 8, and the rack 10 is mounted on each of the frame members 5 in the up-down direction and placed. The lifting member 6 can be moved up and down and stopped by engagement of the pinion 9 and the rack 10 by the drive of the drive 8.

Reference numeral 11 denotes a scaffold member. In this case, the scaffold member is formed on both sides of the elevating member 6 so as to extend in the horizontal direction, and comprises a fixed scaffold material 12 and a telescopic scaffold material 13. A rectangular frame-shaped telescopic scaffold 1 having a frame structure and inserted into the fixed scaffold 12 and formed in a frame shape.
3 is attached so as to be able to expand and contract by a bearing mechanism not shown,
A floor plate 14 such as a lath plate is formed on the upper surfaces of the fixed scaffold 12 and the telescopic scaffold 13, and the telescopic scaffold 13 is configured to be capable of expanding and contracting and stopping by a telescopic mechanism 15 including an electric winch or a manual winch.

Reference numeral 16 denotes a handrail, which is a fixed scaffold 12
And standing on the telescopic scaffold 13.

Reference numeral 17 denotes a scaffold plate, and the supporting pipe frame 1 is provided on the fixed scaffold 12 and the telescopic scaffold 13 on the wall side of the building W.
The scaffold plate 17 is mounted on the supporting pipe frame 18 in a state flush with the floor plate 14.

Reference numeral 19 denotes a support member,
Similarly to the above, the main frame member 4 is formed in a rectangular frame shape having a frame structure by surrounding the main frame member 4, and a support member 19 is provided so as to be able to move up and down along the main frame member 4 by a guide roll 20. Two elevating motors 21 are mounted, and a pinion 22 is mounted on the main shaft of the elevating motor 21, and the pinion 2 is mounted on the rack 10 mounted on each of the frame members 5.
2 and the pinion 2 is
The support member 19 is configured to be able to move up and down and stop by engagement of the rack 2 with the rack 10.

Reference numeral 23 denotes a crane mechanism. In this case, the body 24 is attached to the support member 19 so as to be able to turn around a turning shaft 26 by a turning motor 25, and an elevating arm 27 is mounted on the body 24 by an elevating winch 28. A hanging winch 30 for raising and lowering the hanging hook 29 is attached as much as possible.

In this embodiment, the grounding frame 1 is carried into a construction site and fixed at a predetermined position, and the lifting member 6 is moved up and down along the main frame member 4 in this state. The scaffold member 11 is disposed at a suitable height according to the work site of the building W and is moved up and down, and the scaffold member 11 is expanded and contracted to an appropriate length. In this state, work at a high place can be performed on the scaffold member 11. At the same time, the crane mechanism 23 can perform a crane operation for materials and the like.

Thus, the height of the scaffolding member 11 can be set at an arbitrary height according to the work site of the building W by raising and lowering the elevating member 6, and the scaffolding member 11 can be expanded and contracted to extend the building W. The length can be set appropriately according to the work site, and the work efficiency can be improved accordingly.
The assembling and disassembling operations are facilitated, and the operation costs can be reduced.

The present invention is not limited to the above-described embodiment. For example, the structure and the like of the main frame member 4, the elevating member 6 and the like can be appropriately designed and changed.

[0017]

According to the present invention, as described above, the drive of the elevating motor is controlled.
Stack frame members via rack and pinion by movement
Bound along the main frame member comprising by elevating the elevating member can be installed at any height according to the height of the scaffolding member to the work site, and each of the horizontal direction on the left and right sides of the elevating member
To be set appropriately lengths depending on the work site by stretching the stretchable scaffold projecting scaffold member, on the scaffold member can perform aerial work while using the handrail material in this state, only that The work efficiency can be improved, and the assembling and disassembling work can be easily performed as in the related art, and the working cost can be reduced.

As described above, the intended purpose can be sufficiently achieved.
