Description

[Detailed description of the invention] (Industrial application field) The present invention relates to an assembly scaffolding device.

More specifically, the present invention provides a self-propelled assembly system that is useful for indoor ceiling interior work, etc., and that allows easy adjustment of the area and height of the scaffolding, as well as easy assembly and disassembly, as well as easy change of placement position. It is installed between scaffolding equipment.

(Conventional technology and its problems) Conventionally, in the interior work of ceilings, upper walls, etc. of buildings and other buildings, the necessary height was set each time, and elongated scaffolding boards made of steel or aluminum, stepladders, etc. A large number of rubber bands are brought to the construction site, and workers manually assemble the necessary scaffolding on the spot. The height and width of the scaffolding are changed as necessary to make it easier for workers to work, taking into account the work content, the height of the workers, etc.

On top of the thus assembled scaffolding, materials necessary for ceiling work, such as ceiling finishing materials such as architectural steel base material, base plasterboard, and Rozukuwel decorative board, are placed by hand. The staff climbs onto the scaffolding and performs ceiling work to install the scaffolding.

In addition, the height of the work floor and the required space are important for assembling the ceiling base, wiring and piping for equipment in the ceiling layer, attaching ceiling panels, and installing equipment, all of which involve assembling scaffolding. Once the interior work is completed, the scaffolding is dismantled, the dismantled scaffolding materials are transported to the next location, and the scaffolding is reassembled manually by workers.

As described above, in ordinary ceiling interior work, etc., installing scaffolding is extremely troublesome and consumes a large amount of labor and time. There were also constraints on ensuring safety during installation work, dismantling and transportation work. Manual work was also highly dangerous, which posed a challenge when assembling scaffolding.

On the other hand, recently, iron pipes, swivel wheels, and scaffolding boards have been brought to the site to create movable scaffolding, and scaffolds such as sectional table tennis tables with swivel wheels have been brought to the site to be assembled and moved. Hand-operated ceiling work assembly scaffolds, which can be expanded and combined to create relatively wide scaffolds, are also beginning to be used.

However, even in the case of these improved scaffolds, there is little freedom in changing the height position due to their structure, and workers have to move the assembled scaffolds manually, so there is not much space on top of the assembled scaffolds. It is not possible to store large quantities of materials.

In addition, with the aim of overcoming the above-mentioned drawbacks of conventional work scaffolding, indoor traveling type work carts have begun to appear.

However, although this indoor work trolley has the advantage of allowing workers to ride on it and move up and down, it is only used for installing air conditioning ducts, piping, and lighting equipment. In local work such as
In addition, the materials handled were limited to lightweight and small-sized items. This was a natural thing to do from the perspective of ensuring flexibility in running and raising and lowering. However, for construction work such as interior work on large ceiling surfaces, it is not possible to use indoor work carts, which are designed for local work and can only handle lightweight and small-sized materials.

In this way, until now, a large work area was required for the work of removing steel base materials, pasting base ceiling boards, pasting finishing boards, etc., which require the largest amount of work in interior work such as indoor ceilings. However, a scaffold that can load the necessary materials and move on its own, has a large degree of freedom of work, is easy to install, is easy to operate, and has excellent safety has not yet been realized.

This invention was made in view of the above-mentioned circumstances, and it eliminates the drawbacks of conventional scaffolding, allows easy adjustment of the scaffolding area and height, has excellent work freedom, and is easy to assemble and dismantle. Of course, distribution! The purpose of the present invention is to provide a self-propelled assembly scaffolding device that is easy to change its position and has excellent safety.

(Means for Solving the Problems) The present invention solves the above-mentioned problems by providing a drive truck having a stage that can be raised and lowered and driven by a power source, and a stage height adjustable and free wheels.
