[0001]
[Industrial application fields]
The present invention relates to a scaffold device suitable for the use of a framework scaffold.
[0002]
[Prior art]
As this type of conventional framework scaffold, for example, what is disclosed in Japanese Utility Model Laid-Open No. 4-129256 is known.
[0003]
As shown in FIG. 14, this framework scaffold is composed of a frame 3 made up of building frames 1, 1 that are continuously inserted in the vertical direction, and a horizontal frame 2 that is installed between the building frames 1, 1. Then, after arranging a large number of the frame bodies 3, the scaffolding plates 4, 4 are constructed on the horizontal member 2 via hooks, and the baseboards 5, 5 are arranged on both sides of each scaffolding plate 4, 4. The baseboards 5 and 5 are connected to the building frames 1 and 1 which also serve as an upper handrail by a wire or the like.
[0004]
[Problems to be solved by the invention]
The above-mentioned conventional scaffold using the scaffold board has the following problems.
[0005]
First, since the scaffolding plates 4 and 4 are usually formed to be elongated in order to reduce the weight, even if a plurality of, for example, two scaffolding plates 4 and 4 are arranged side by side on the horizontal member 2, A gap L is inevitably formed between the scaffold plates 4 and 4 and the baseboards 5 and 5.
[0006]
For this reason, there is a risk that nails, bolts, tools, small building materials, etc. on the scaffolding plates 4 and 4 may fall downward through the gap L.
[0007]
Secondly, the scaffolding plates 4 and 4 are continuously arranged in the longitudinal direction. In this case, each of the scaffolding plates 4 and 4 hooks the horizontal member 2 with hooks protruding from both front and rear ends. For this reason, a gap corresponding to the width of the two hooks is formed between the scaffolding plates 4 and 4 adjacent to the front and rear, and the tool on the scaffolding plate may fall downward from this gap in the same manner as described above. There is.
[0008]
Therefore, a first object of the present invention is to provide a scaffold device in which no gap is generated on both the left and right sides of the scaffold plate.
[0009]
A second object of the present invention is to provide a scaffold device in which a gap is not generated between adjacent plate bodies when a plurality of scaffold plates are connected in the front-rear direction.
[0010]
