Description

[Detailed description of the device]

[0001]

[Industrial applications]

 This invention relates to a folding simple scaffold used at a construction site.

[0002]

[Prior art]

 Until now, for example, a scaffold as shown in FIG. 6 has been used. That is, using a stepladder or a horse, a scaffolding board was placed on the scaffolding board, and then the scaffolding board and the stepladder or the horse were fixed with a steel wire board or the like to form the scaffolding.

[0003]

[Problems to be solved by the device]

 The scaffold shown in FIG. 6 has the following drawbacks. Since the scaffolding board is placed on a stepladder or horse and fixed with iron wires, etc., if the fixation is not sufficient, there is a risk of the scaffolding rattling or falling off during work, causing a fall. In addition, since it is necessary to place a stepladder and a horse on top of which a scaffolding board is placed and fix it with iron wires, there is a drawback that it is troublesome to brush and move.

[0004]

[Means for Solving the Problems]

 In order to solve this problem, we devised a scaffold that integrates the stepladder and the scaffold and incorporates a folding mechanism. That is, the stepladder and the scaffolding are connected by a connecting hardware, the leg is flexibly built inside the scaffolding board of the scaffolding, and the leg is pulled out from the scaffolding board for use at the construction site.

[0005]

[Action]

 With this device, the scaffolding and moving can be done easily, and the scaffolding can be easily assembled on site. In the present invention, the stepping part and the scaffolding part are integrated, and the stepping part and the scaffolding part are flexibly connected by a hinge or the like. In addition, legs are flexibly incorporated inside the scaffolding plate of the scaffolding, and this leg constitutes one leg as a scaffolding for field work. When using it, raise the legs built into the scaffolding board and support and fix it with the support material.

[0006]

【Example】

 An embodiment of this invention will be described with reference to FIGS. FIG. 1 is a perspective view showing an assembled state of the present invention, and FIGS. 2 and 3 are a side view and a plan view of the assembled state. FIG. 4 is a side view showing a folded state. The upper end 12 of the stepladder 11 and one end 21A of the scaffolding plate 21 of the scaffolding part 2 are flexibly connected by a connecting fitting such as a hinge 18. The leg 31 connected to the scaffolding part 2 is flexibly attached to the other end 21B of the scaffolding plate 21 and is stored in the scaffolding plate 21 in advance.

At the time of working at a high place on a construction site, the folded simple scaffolding of FIG. 4 is carried into the site and assembled in the following order. First, the connecting part 17 between the stepping part 11 and the scaffolding part 2 is spread out through the hinges 18 so that the upper end part 12 of the stepping part 11 and the scaffolding plate 21 of the scaffolding part 2 are substantially horizontal. Then, the leg 31 is pulled out from the scaffolding plate 21, and is pulled down until the scaffolding plate 21 and the leg are substantially at right angles. As a result, the scaffolding plate 21 is kept substantially horizontal with both ends supported by the stepladder 11 and the legs 31.

Further, in order to fix both feet of the stepping part 11, the upper end supporting part 13 and the intermediate supporting part 14 are pushed out and completely fixed, and the supporting part 22 on the scaffolding part supports and fixes the stepping part 11 and the scaffolding plate 21. Then, the legs 31 and the scaffolding plate 21 are supported and fixed by the scaffolding plate side support member 23. This completes the assembly of the simple scaffold.

When the construction site for work at high places is long horizontally, two sets of simple scaffolds can be combined and used. FIG. 5 shows the usage state. The leg 31 of the simple scaffold on the A side and the leg 31 of the simple scaffold on the B side are connected and fixed by the connecting members 32 and 33 which are attached to the upper and lower portions of the leg 31 in advance. This makes it possible to perform work at heights that are twice as long as the length of work that can be performed with a single simple scaffolding, and improve the efficiency of on-site work.

[0010]

[Effect of device]

 In the present invention, the stepladder and the scaffold are integrated, and they are flexibly connected by a connecting metal fitting such as a hinge, and the legs are flexibly built inside the scaffolding plate of the scaffold. It can be loaded into a construction site in a folded storage state and assembled as a unit at a required place. Therefore, the labor and time for paying and moving can be greatly reduced. In addition, since the scaffolding part, the scaffolding plate and the legs are integrally configured, it is possible to prevent a fall accident at the time of working at a high place due to the scaffolding plate being dislocated or displaced.

[0012] Further, since two folding simple scaffolds can be connected and fixed through the legs, it is possible to efficiently perform work at a height that is twice as long as the work that can be performed by a single simple scaffold.
