Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is located at the lowest end of a folding type unit such as a folding type scaffolding unit or a staircase unit at a construction site, and the folding type unit is stable and self-supporting. The present invention relates to a foldable base unit.

[0002]

2. Description of the Related Art The applicant has made various developments as a folding scaffolding unit / staircase unit at a construction site. For example, "scaffolding unit", "folding staircase unit" filed on February 28, 1991, May 2, 1991
"Folding scaffolding unit", "Folding stair unit" filed on 7th patent, "Folding scaffolding unit" filed on July 16, 1991, etc.

[0003] These are used as standing foldable scaffolds or stairs at a construction site by erected four or four or more building sites.

[0004]

However, when the ground on which the building is erected is sloping or soft, the erected scaffolding unit or the staircase unit itself is inclined and the folding unit is used. The work could be dangerous. In addition, when the folding unit has a large inclination, the unit cannot be used.

On the other hand, in order to avoid such a situation, it is troublesome to pour concrete or the like only at a position where a folding unit such as a scaffolding unit or a stair unit is erected to form a foundation, which causes a delay in the construction period. It was.

Therefore, the present invention was created in order to solve the above-mentioned problems, and in the construction work, for example, the foldable scaffolding unit or staircase unit is located at the lowermost end of the foldable unit. The unit can be stably self-supporting, can be folded by itself, is compactly stored and easy to move, and is also a foldable type that is positioned between the foldable unit and the jack base. The purpose is to provide a base unit.

[0007]

That is, a base frame 3 having a pair of left and right rear buildings 1, 2 and horizontal members 4, 5 are horizontally swingably connected to the rear buildings 1, 2, respectively. Front side constructions 6 and 7 are connected to the horizontal members 4 and 5, and a pair of left and right side frames 8 and 9 are provided inside the base frame 3 so as to be freely foldable. Since the unit main body 11 is composed of the bottom frame 10 that is connected and swings vertically from the horizontal position, the unit main body 11 can be folded with one touch. Therefore, dismantling and withdrawal work is extremely easy. Further, since all the constituent parts are connected to the base frame body 3, there is an advantage that constituent parts can be prevented from being lost and the storage management is easy.

Further, since the front side frame 13 which swings vertically from the horizontal position and stands upright on the front side constructions 6 and 7 is attached to the open side edge of the bottom frame 10, the unit main body 1
1. The overall robustness can be sufficiently ensured. Therefore, if the unit body 11 is installed at a predetermined position, the unit body 11
Other folding scaffolding units or staircase units can be connected on top of them for safe use. In addition, the scaffolding unit or the staircase unit can be used promptly without the need to pour concrete or the like into the position where the scaffolding unit or the staircase unit is erected in order to stably erect the scaffolding unit or staircase unit.

On the other hand, if a plurality of unit main bodies 11 are arranged side by side and connected by the connecting body 24 and the jack base connecting body 35, the length of the present invention for stably erecting the scaffolding unit and the staircase unit can be constructed, for example. It can be arbitrarily set according to the size of the building.

In addition, the connecting body 24 includes a connecting base portion 25,
Inserted from above into the connection holes 23 formed at the upper ends of the building sites 1, 2, 6 and 7 which are located below the connection base portion 25 and which form one unit body 11 and the other unit body 11 which are juxtaposed. The two connecting pipes 26 and the connecting base 25, which are located above the connecting base 25, are inserted into the connecting holes B formed at the lower end of the building A that constitutes another folding scaffolding unit or staircase unit from below. When it consists of two connecting pipes 27,
The plurality of unit main bodies 11 can be easily and reliably connected.

In addition, at the lower end of each of the building bases 2.1, 7 and 6 which constitute the connecting base and one unit main body located above the connecting base and arranged side by side in the lateral direction, and the other unit main body. Two connecting pipes inserted from below into the drilled connecting holes 36 and a jack base 34 located below the connecting base.
When the jack base coupling body 35 including a coupling pipe that is coupled to the unit body 11 is used, the plurality of unit bodies 11 can be reliably coupled and the height of the coupled unit bodies 11 can be arbitrarily adjusted by the jack base 34.

In addition to the above, according to the present invention, the base frame 3 and the base frame 3 are provided.
A pair of left and right side frames 8 and 9 that are foldable inside the unit form a self-standing unit body 11, which is extremely simple in structure, and thus is preferable for mass production, and the product can be provided at low cost. It has various industrially beneficial effects.
