ト的にも高価なものとなつていた。(Prior Art) Traditionally, in various building construction projects, when carrying out ceiling covering, wall finishing, and various other interior work in concrete stairwells,
Constructing and installing simple scaffolding. An example of this is a structure in which scaffolding boards are strung between stepladders set on the floor, or a framework in which pipes are assembled from above the floor and scaffolding boards are also spanned between them. However, even though such temporary scaffolding can be safely installed on a horizontal floor surface such as a landing, it is easy to topple over the stairs because it is sloped in steps. It was extremely dangerous. Not only that, but because it is set and framed on the floor, it obstructs the passage of workers.
There were also problems in bringing in and taking out various equipment, and in general, installing and dismantling them was troublesome, the workability was poor, and the cost was high.

This has a double-tubular structure with an expandable inner tube and an outer tube, with a male thread at the upper end that screws into the insert, and a clamp fitting at the lower end to hold the base pipe of the scaffold. The mutual length adjustment and fixation of the inner and outer tubes was accomplished by inserting locking bolts into respective adjustment holes.

It is suspended and supported along the vertical direction by being screwed and fixed to an insert I buried and exposed in a ceiling slab C in a concrete stairwell in various building constructions. This hanging member 1 is telescopic and has a clamp fitting 24 at the lower end, and allows pipes of different sizes to be slidably fitted into a double structure, and a predetermined fitting is achieved. By fixing at the length position, the overall length is set and the support height position from the ceiling slab C is maintained. Normally, staircases with a height of around 4m are constructed so that the length can be adjusted within the range of 1.5 to 2m.
Of course, it is not limited to this.

な調整を簡易迅速に行なえる。 Specifically, an upper connecting pipe 6 is attached to the upper end of the cylindrical main body 2.
An anchor bolt 11 screwed to the insert I is slidably connected to the upper connecting pipe 6, and a lower connecting pipe 18 is screwed to the lower end of the cylindrical body 2. The lower connecting pipe 18 is rotatably connected to a clamp fitting 24 for gripping a cloth board support member 30, which will be described later. As shown in the drawings, an upper connecting pipe 6 and a lower connecting pipe 18 having a smaller diameter than the cylindrical main body 2 are fitted into the upper and lower ends of a large diameter cylindrical main body 2 in a double-tubular shape. Adjustment and fixation of the fitting length between the cylindrical body 2 and the upper connecting pipe 6 are performed using one through hole 3 drilled in the upper end of the cylindrical body 2 and a plurality of through holes bored in the upper connecting pipe 6. 7
This is done by aligning the upper connecting bolts 4 through the through holes 3 and 7 with the nuts 5. By doing this, the approximate length of the entire hanging member 1 can be adjusted. possible. On the other hand, the fitting length between the cylindrical body 2 and the lower connecting pipe 18 can be adjusted and fixed by welding and fixing the through hole 13 bored at the lower end of the cylindrical body 2 and the upper end of the lower connecting pipe 18 by internal fitting. A retractable bolt 1 is inserted into the cylindrical body 2 and screwed into the retractable nut 17 so as to be freely retractable.
The lower connecting bolt 14 inserted through the head of the lower connecting bolt 14 is fixed with a nut 15, and by rotating the lower connecting pipe 18, the lower connecting bolt 14 is inserted and retracted from the cylindrical body 2 by screw feeding means using the advance/retreat bolt 16 and the feed nut 17. By doing so, the length of the entire hanging member 1 can be finely adjusted. In particular, the clamp fitting 24 located at the lower end after connection to the insert I
Fine adjustment of the height position of the cloth plate support member 30 to be held by the cloth board support member 30 can be easily and quickly performed.

ねじ送り作用を常時円滑なものとさせる。 The anchor bolt 11 also has a fixing bolt 9 inserted into the nut 10, which is inserted through a through hole 8 formed at the upper end of the upper connecting pipe 6 and a swing ring 11A formed at the rear end of the anchor bolt 11 itself. By stopping it, it is connected to the upper connecting pipe 6, and the swing ring 11A
By being able to swing freely at any position, when fixed to the insert I, the hanging member 1 itself can be suspended vertically or at an angle. In addition, 12 in the figure is a cap, and the anchor bolt 11 at the upper end opening of the upper connecting pipe 6 is
This prevents dust and other substances from entering the cylindrical body 2 when it is suspended, and in particular, it keeps the screw feeding action of both the reciprocating bolt 16 and the feed nut 17 smooth at all times. Make it worth it.

Moreover, since the scaffolding itself according to the present invention is made up of a basic combination of the hanging member 1, the cloth plate support member 30, and the cloth plate member 40, it is extremely difficult to carry it to a temporary construction site, assemble it, and furthermore dismantle it and carry it out after use. It is easy to use, and the various structural frame members used are lightweight, and their connection and assembly are simplified, so compared to conventional scaffolding of this type, it does not require specialized workers. Assembling and disassembling work time can be cut in half, resulting in significant savings in construction costs. In addition, since it is a hanging structure, there is no need for a support construction member below the cloth board member 40, and a large space is secured as it is, which can be used as a passageway for passage of workers and for loading and unloading various equipment. Helpful and furthermore,
It is also possible to proceed with floor construction at the same time.

Since it has a clamp fitting 24 at the lower end, it can be firmly suspended from the ceiling slab C, and can sufficiently support the loads of the cloth board support member 30 and cloth board member 40, as well as workers and others. The height positions of the cloth plate support member 30 and the cloth plate member 40 for securing a working space can be freely adjusted and set, and in particular, the screw feeding means 16,
17 allows for fine adjustment of the length, making it highly versatile in the field.
