Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a self-propelled moving scaffold. More specifically, the present invention relates to a temporary scaffold that is useful for finishing works such as ceilings inside buildings, has excellent workability, and is easy to assemble and relocate.

(Conventional technology and its issues) Traditionally, at finishing work sites such as ceilings inside buildings under construction, portable stepladders and scaffolding materials were assembled on site and fixed to the stepladder with rubber bands, etc. Temporary scaffolding has been constructed using methods such as: In either case, these methods require that the temporary scaffold be moved manually after the specified work is completed, and in the case of the method of fixing the scaffolding materials to a stepladder, a relatively wide temporary scaffold is required. Although scaffolding could be erected, it had to be dismantled and reassembled at another location after the designated work was completed.

Manual movement, transportation, and repeated disassembly and assembly of scaffolding were extremely troublesome, and the effort and expense involved was enormous. Also, such transportation, disassembly, and assembly at construction sites was dangerous.

In order to solve this problem, a small, indoor-use elevated work vehicle that can be raised and lowered has been developed and is beginning to be used at actual construction sites. This aerial work vehicle was originally developed for work such as installing highway lighting, telephone lines, and power transmission lines, but has been adapted for indoor use. It is characterized by being moved by power rather than by human power, with excellent flexibility in selecting temporary locations, and by easy height adjustment.

However, these aerial work vehicles are small, the range in which workers can move is extremely limited, and the size and amount of materials that can be loaded are severely limited. It can only be used for installing equipment, etc. or for local repair work.

Work such as finishing ceiling surfaces at construction sites requires work to cover the entire surface of a wide ceiling surface, so there is a problem that aerial work vehicles with restricted movement of work tools cannot be used in practice. there were.

This invention was made in view of the above-mentioned circumstances, and it overcomes the drawbacks of conventional temporary scaffolds such as movable assembly scaffolds or aerial work vehicles, and saves the labor and expense of transporting, dismantling, and assembling scaffolds. The purpose of the present invention is to provide a new temporary scaffolding that can greatly reduce the number of workers, provide greater freedom of action for workers, have excellent work efficiency, and is easy to assemble and relocate.

(Means for Solving the Problems) The present invention solves the above problems by providing a self-propelled mobile cart having a lifting device, and support legs at the ends that can be loaded onto the cart and can be connected in a plane. To provide a self-propelled mobile scaffold consisting of a plurality of panels that can be freely installed vertically, the panels connected in a plane being supported by an elevating device of a self-propelled mobile cart, and being movable.

The self-propelled trolley is movable using power from a battery or the like, and its lifting device allows the floor surface of the trolley to be raised and lowered. These operations may be controlled remotely. Also, the height of the support legs that can be freely hung from the panel edge may be adjusted freely. With the support legs hanging from the section and the elevating floor surface of the self-propelled trolley,
I support this.

The entire surface of the connected panels serves as scaffolding for workers.

The number of panels to be connected may be determined depending on the size of the construction site, etc.

Hereinafter, the self-propelled mobile scaffolding of the present invention will be explained in more detail by showing examples.

First, Figure 1 shows a self-propelled mobile trolley (1) with a panel <2
〉 is loaded and transported to the work site.

This mobile trolley (1), which runs on wheels (3), is loaded with panels (2) and a storage box (4).For example, the size of this mobile trolley (1) is 90mm.
0 ma, length 2000 m+, height 500 tm,
Panel (2) size is medium 900fi, length 2000m
It is made of aluminum alloy, resin, lightweight steel plate, etc., and is 100 m tall, and nine of these can be loaded.

The storage box (4) also houses the support legs that are installed vertically on these panels and the safety handrails that are installed around the scaffolding. panel(
2) and this storage box (4) are loaded using a moving trolley (1).
It is fixed via side plates (5) and fixing bands (6) on both sides of the. In addition, the moving trolley (1) is operated using a remote switch (7). It can be moved forward, backward, left and right, and also in right angle directions. Of course, it is not limited to these examples. .

FIG. 2 illustrates the ascending and descending states of the mobile cart (1). The above-mentioned panels (2) and the like are loaded on a floor surface (8) which can be raised and lowered hydraulically, mechanically, or electrically. For example, this mobile trolley (1) has the ability to lift objects weighing 1000 kg, and the maximum height of the floor surface (8) is 1000 kg.
500+mm, which is sufficient to handle work with ceiling heights up to 3000 ohm.

FIG. 3 shows a state in which the aluminum alloy panel (2) illustrated in FIG. 1 is assembled and supported on the movable trolley (1) in a planar connection.

In this example, nine panels (2) are connected.

This connection can be easily made using simple fixing fittings. The ends of the panels (2) may be fitted into each other or may have a locking structure.

At the edge of the panel (2), support legs (9) whose height is manually adjustable are vertically disposed on the peripheral edge, and a movable wheel M (10) is attached to the lower end.

In this state, it forms a self-propelled scaffold with a diameter of 2,700 mm, a length of 6,000 + m, and a floor height of 1,500 m.

Movement is possible by operating a remote switch (7) by a worker on this scaffold.

There is no need to dismantle, transport, and assemble scaffolding, let alone transport it manually.

The connection of the panels (2) can be configured as follows, for example, depending on the size of the space at the work site.

Number of panels: 2 Scaffold dimensions: width 900B x length 4000m Number of panels
Dimensions of 3 scaffolds: width 900m + length 6000m Number of panels 6 scaffolding dimensions: width 1800m x length 6000m In addition, the third
Scaffolding consisting of 9 panels (2) of the size shown in the figure
When the platforms are connected, it becomes a scaffold with a width of 5,400w and a length of 6,000m+, which can be used at any work site.

When forming a scaffold with a large area, the planar connected panels (2) are supported by a plurality of movable carts (1),
It can also be moved.

When moving the scaffold, the panel (2) is lifted and moved by the lifting device of the moving cart (1) until the free wheel (10) at the lower end of the support leg (9) shown in Figure 3 is slightly above the floor. can be done.

By doing this, the supporting legs (9) can move smoothly without getting caught on the floor.

A safety mechanism or a sensor mechanism may be attached to the movable trolley (1) for these elevations and movements.

For example, in the example shown in Figure 3, the weight of panel (2) is 3.
If the weight of the support leg <9> is 8kt, the total weight will be approximately 40kg, including the safety handrail (11>) attached to the connecting panel (2>).
It will be about 0 kg. Ceiling board gypsum board 200 for this
Even if 1,401 qr of kg and two workers are added, the maximum load of the mobile cart (1) is 10,001 qr or less, which can be sufficiently supported.

Of course, the present invention is not limited to the above examples, and it goes without saying that various shapes and structures are possible.

(Effects of the Invention) As explained in detail above, this invention provides a temporary scaffolding that has excellent workability, is easy to assemble and relocate, can be expected to significantly improve safety and save labor, and is economical. provided.
