[Detailed description of the device]

[0001]

BACKGROUND OF THE INVENTION The present invention is an air mat scaffold having a novel structure. More specifically, it is an air mat scaffold that can be used for multiple purposes such as an internal scaffold in a building, a safety mat instead of a net, and a temporary stage for an event.

[0002]

2. Description of the Related Art Heretofore, in this type, the following has been done. Conventional temporary scaffolds are made of iron and can be assembled with many parts.

[0003]

The problems described in the prior art have the following problems. 1. Conventional temporary scaffolds, temporary stages, etc., use a steel plate walking board as a round pipe of a steel pipe, are mainly used as external scaffolds, and are assembled by a large number of parts, which is poor in workability. In addition, the weight is heavy, labor is required for transportation and assembly, and only a man can perform the construction. 2. In addition, since the external scaffolding is built up even in high-rise areas such as at the construction site, the floor finishing material is damaged, or the base material such as walls and ceilings, finishing materials, openings, and frames are used during assembly, removal, and transportation. Materials and doors are often scratched and dirty. Therefore, it is necessary to protect it with a curing sheet or curing veneer. However, at present, it is impossible to protect scratches.

3. It takes labor and time to assemble and remove,
A truck is required for transportation, and construction costs are high. 4. The temporary scaffolding requires labor and time, requires a truck for transportation, and construction costs are high. 5. Temporary scaffolding assembled by simply placing a step board on a stepladder in a normal room is poor in safety and work efficiency on the temporary scaffolding is poor. 6. It is dangerous to work with ladders at high places such as crossing and painting work in finishing work, and temporary scaffolding is required again for safety. That is, in the case of a normal ceiling height (H = 2400 mm or so), since the step board is placed on the stepladder as a scaffold, the stability is poor and the work efficiency on the step board is poor. 7. Accidents often occur when using temporary scaffolding or walking boards, such as when building a building.

The operation will be described together with the effects.

[0015]

Since the present invention is constructed as described above, it has the following effects. 1. The air mat body 2 enormous by a compressor or an original compressor that a construction worker such as a carpenter always uses is laid on the floor inside the building site, and it is connected to the front, rear, left, right, and up and down to perform ceiling work etc. inside the building. A foothold can be easily secured. In this case, by spreading the upper surface mat 3 set to a certain size on the upper portion (top end portion) of the air mat bodies that are continuously provided, the feet of the worker can be stabilized and the work efficiency can be improved. In this case, the conventional walk board 5 and control panel may be used. Reference numeral 6 is a curing sheet, and 7 is a stairway which is formed by a compressor or the like to be enormous like the air mat body.

2. For horizontal connection in a plane, a male or female planar adhesive tape provided at a corner of each air mat body 2 can be adhered to easily and surely form a temporary scaffold even in a space having a large floor area. it can. Further, the vertical connection is performed by adhering a male sheet-shaped adhesive tape 2E1 on the upper surface 2E of each air mat body 2 and a female sheet-shaped adhesive tape 2F1 on the lower surface 2F, and assembling them three-dimensionally, and at a high place such as a blow-through. Can be used as a temporary scaffold. For this reason, temporary scaffolding that enables safe and speedy work such as assembling base materials for walls and ceilings at high places, applying finishing materials, painting, and the like becomes possible, and workability at the site is improved. 3. When used as an internal scaffold at a construction site, it does not damage the finishing material, so no special curing sheet or curing veneer is required. Further, the scaffolding assembly (on-site assembly by iron pedestal, wood), the curing sheet, and the curing veneer, which have many conventional problems (non-safety, scratches, construction speed), become unnecessary.

4. Since it is easy to inject air with the compressor that is always used at the construction site, the scaffolding installation work as a temporary work can be completed speedily, saving labor. Further, since the air bleeding can be completed quickly, the scaffold disassembly work can be completed very easily. After air is discharged, it is small and lightweight, so it can be transported by passenger car or wagon without the need for a large truck. in this case,
After discharging the air, the upper surface mat 3 can be set in the folded state for easy storage and transportation. 5. In case of a dangerous situation such as when the building is overwhelmed, the air mat body 2 alone is used on the floor instead of the conventional safety net to prevent the danger of dropping. 6. These can be used not only for woodwork, but also for construction of heavy structures and civil works, and can contribute to the safety of human life.
