[Industrial applications]

 This invention relates to an assembly scaffolding device. More specifically, the present invention has a simple structure that is useful for interior work on the interior ceiling surface, where the scaffolding area and its height can be easily adjusted, and not only its assembly and disassembly, but also the change of its layout position. Assembling scaffolding device.

[0002]

[Prior art and its problems]

 Conventionally, in interior work such as ceilings and upper wall surfaces of buildings such as buildings, the required height is set each time, and a number of slender scaffold plates such as iron or aluminum, stepladders, rubber bands are brought to the construction site. , The required work scaffolds are assembled on the spot by the manual labor of the workers. The height and width of the scaffold are appropriately changed as necessary in consideration of the work content and the height of the worker's back so that the worker can work easily.

On the scaffold thus assembled, materials necessary for ceiling work and the like, for example, a ceiling finishing material such as a steel base material for construction, a plaster board for foundation, and a Rockwell decorative board are manually worked. Then, the worker rides on the scaffolding and performs the ceiling work to mount it. Moreover, the work floor height and required space differ for each work such as assembling the ceiling groundwork, wiring and piping the equipment inside the ceiling, attaching the ceiling board, and installing equipment, and each scaffold is assembled. When the interior work is completed, the scaffolds are dismantled, the dismantled scaffolding materials are transported to the next place, and the scaffolds are assembled manually by workers again.

[0004] As described above, installation of scaffolding is very troublesome in normal ceiling interior construction work, and labor and time are very large. There were also restrictions on the safety of installation work, dismantling and transportation work. There was a great risk of manual work, which was a problem in scaffolding assembly. On the other hand, recently, iron pipes, swivel wheels, and scaffolding boards are brought to the site to assemble them to create a mobile scaffolding. A hand-operated ceiling work assembly scaffold that expands this and combines it into a relatively wide scaffold is also beginning to be used.

However, even in these improved scaffolds, for example, in the case of a scaffolding device assembled by assembling a dedicated iron pipe, due to its structure, there is little flexibility in changing the height position, and the assembly or assembly is difficult. It does not significantly reduce the labor and time required for disassembly. Also, in the case of an assembly-type scaffolding with free wheels, a large scaffolding area can be formed relatively easily by combining these, but since each scaffolding is not connected, a large amount of scaffolding is needed. It is difficult to move with the materials of.

The present invention has been made in view of the circumstances as described above, and it is possible to eliminate the drawbacks of the conventional scaffolding device, to easily form a scaffolding of a desired size, and to improve the working flexibility. It is an object of the present invention to provide an assembly scaffolding device having a simple structure, which is excellent in safety and safety, and can be easily moved not only in its assembly and disassembly, but also in its disposition position.

[0007]

[Means for Solving the Problems]

 In order to solve the above problems, the present invention comprises a scaffolding plate having an end locking portion, and a supporting leg unit having a supporting means of this scaffolding plate and a detachable mutual joint means, which can be combined and connected. Provided is an assembly scaffolding device. Also, in this invention, the supporting leg unit is composed of a taper-shaped leg portion having free wheels, a height-adjustable support column, and a horizontal crosspiece having joint means at both ends, and the end locking of the scaffold plate. The portion is formed of a hook-shaped body that is locked to the horizontal rail of the support leg unit, and further, the joint means at both ends of the horizontal rail is composed of a bent piece having a hollow portion and a disk-shaped protrusion. Is also a preferred embodiment.

[0008]

[Action]

 In the assembled scaffolding device of the present invention, a plurality of supporting leg units are arranged in parallel, and another supporting leg unit is arranged in series to each of these supporting leg units via respective joint means so as to face each other. Lock the scaffolding board between the supporting leg units. Therefore, a scaffold of a desired size can be assembled quickly and easily. Further, the dismantling and transportation after dismantling are easy.

Further, in a preferred mode of the assembly scaffolding device of the present invention, since the height of the support leg unit is adjustable, the height can be adjusted in advance to obtain a desired height according to the work purpose. The scaffold can be assembled. Also, the free wheels of the support leg unit can also collectively move freely in any direction in the assembled state.

【Example】

 Hereinafter, embodiments will be described with reference to the accompanying drawings, and the assembled scaffolding device of the present invention will be described in more detail. FIG. 1 is a perspective view illustrating a supporting leg unit, which is one of the constituent members of the present invention.

As illustrated in FIG. 1, the supporting leg unit (1) used in the present invention has a pair of supporting legs (2) and both ends fixed to a column (3) of these supporting legs (2). It consists of a horizontal rail (4). Of these, the support leg (2) has, for example, a tubular holding member (7) fixed to a Taber-shaped leg portion (6) having a pair of free wheels (5), and a column (3) is fixed to the holding member (7). ) Can be freely inserted and fixed, so that the horizontal rail (4) can be set at any height.

On the other hand, the horizontal rail (4) has joint means (8a) (8b) at both ends thereof. These joint means (8a) and (8b) are, for example, as shown in the perspective view of the main part in FIG. 2, one joint means (8a) is a bent piece having a hollow part, and in this hollow part, The disc-shaped projection, which is the other joint means (8b) of the other support leg unit (1), is inserted from above or below and connected. It should be noted that by making one joint step (8b) such a disc-shaped protrusion, it is not necessary to strictly match the vertical positions of the joint means (8a) (8b) when connecting the joint means (8a) (8b). Also, instead of lifting one of the supporting leg units (1), tilt the supporting leg unit (1) to the side and place the tilted supporting leg unit (1) upright with the joint steps (8a, 8b) aligned. It is also possible to connect these while making them. Moreover, such a disc-shaped projection has an advantage that rattling does not occur at the time of connection because the two points on the circumferential surface of the joint means (8a) are always in contact with the hollow portion.

FIG. 3 is an exploded perspective view showing an example of assembling the scaffold plate, which is another component of the present invention, and the scaffold plate and the supporting leg unit. As illustrated in FIG. 3, the scaffolding plate (9) used in the present invention has end engaging portions (10) made of, for example, hook-shaped bodies on both end edge surfaces thereof, and these end engaging members are engaged. The stoppers (10) are locked to the cross rails (4) of the two support leg units (1) arranged to face each other to form a scaffold.

FIG. 4 is a perspective view showing an embodiment of the assembly scaffolding device of the present invention assembled in this manner. For example, in the case of the assembled scaffolding device shown in FIG. 4, the two supporting leg units (1) connected by the respective joint means (8a) (8b) are made to face each other by the respective horizontal rails (4). Are arranged in three rows, and the scaffolding board (9) is bridged over these cross rails (4) to form a scaffolding of a desired size.

In the scaffolding device of the present invention assembled in this manner, all the constituent members are connected to each other, so that foot scenes are not separated. Therefore, the degree of work freedom and safety are extremely good. Further, even when the installation place is moved by the free wheel (5) of the support leg unit (1), the material etc. can be moved while being placed on the scaffold.

Of course, the present invention is not limited to the above examples, and it goes without saying that various modes are possible in terms of the shape and the detailed structure of each component.
