Description

[Detailed Description of the Invention] [Industrial field of application] The present invention relates to a steel scaffolding plate installed along the periphery of a builder.

[Prior Art] For scaffolding plates for construction, a plurality of single scaffolding plates each having a reinforcing edge formed by bending both sides of a thin steel plate are arranged in parallel, and both longitudinal ends thereof are bent into a substantially U shape. It is inserted into the frame and fixed by spot welding.

After dismantling the scaffolds with the completion of the construction work, these scaffolding plates for construction are prepared for the next work by removing the deposits such as concrete and paint adhered to the scaffolding plates during the construction work with a keren machine. I am trying.

[Problems to be solved by the invention] However, since this kind of keren machine removes adhered substances by giving an impact to the surface of the scaffolding board, the scaffolding board is placed on a carrier device and sent to the keren machine for removal. When performing the work, the spot welds for fixing the scaffold plate and the frame may be disengaged by the impact of the scraper machine, and the scaffold plate may be separated and the scaffold plate may drop from the transport device. In this way, if the scaffolding plate falls out of the transport device, it will hinder the operation of the scaffolding machine, and the scaffolding board must be removed by temporarily stopping the scaffolding machine, which requires time and labor and the operating efficiency of the scaffolding machine. Will be reduced.

In view of the above points, the present invention has been devised so that the scaffolding board does not come apart when the scaffolding board is impacted by the scaffolding work even if the spot welding between the scaffolding board alone and the frame comes off. The purpose is to propose.

[Means for Solving the Problems] In order to achieve the above-mentioned object, the present invention appropriately arranges a plurality of scaffolding plates arranged in parallel at the upper surface of a frame body that is bent in a substantially U-shape to fix both ends of the scaffolding plate. Provided is a scaffolding board for construction characterized in that a holding piece is formed by cutting it off with, and the upper edge of the scaffolding board alone is fitted into a gap between the upper surface part of the frame body and the holding piece to fix the frame body. It is something to do.

[Operation] In the construction scaffolding according to the present invention, a holding piece cut off at an appropriate interval is formed on the upper surface of the frame body, and the upper end of the scaffolding board is placed in the gap between the upper surface portion of the frame body and the holding piece. Since the frame body is fixed by inserting the edge, even if the spot welding between the scaffold plate and the frame body comes off due to an impact by the keren machine, the scaffold plate itself does not come apart.

[Embodiment] An embodiment of the present invention will be described below with reference to the drawings.

The scaffolding plate 1 for construction has a plurality of scaffolding plate units 3 each having a reinforcing edge 2 formed by bending both sides of a thin steel plate cut to an appropriate length in parallel and forming a substantially U-shape at both ends in the longitudinal direction. The formed frame 4 is fitted and fixed by spot welding or the like. Further, on the side surface of the frame body 4, a hooking metal fitting 5 for hanging between the horizontal members of the pipe scaffold is fixed.

On the upper surface portion 4a of the frame body 4, there are formed holding pieces 6 which are cut off at appropriate intervals along the longitudinal direction of the frame body 4.
As shown in FIG. 3, the holding piece 6 is formed by bending the latching metal 5 side by pressing and cutting off the scaffolding plate single body 3 side so that the gap between the holding piece 6 and the upper surface 4a of the frame body 4 is reduced. The thickness of the scaffolding plate alone 3 is set to be approximately the same.

When fixing the frame body 4 to the scaffolding plate single body 3, the frame body 4
The scaffolding plate single body 3 and the frame body 4 after the upper surface end edge 3a of the scaffolding plate single body 3 is inserted into the gap between the upper surface part 4a of the
Is fixed by spot welding.

In this embodiment, the steel plate on the upper surface portion 4a of the frame body 4 is cut off to form the holding piece 6. However, the deformation of the holding piece 4 within the scope of the present invention is included in the present invention. is there.

Then, when the scaffolding board with the adhered matter such as concrete or paint is passed through the keren machine to remove the adhered matter,
Even if the spot welding between the scaffolding plate single body 3 and the frame body 4 is released due to the impact, the upper surface edges 3a at both ends of the scaffolding plate single body 3 are held by the upper surface portion 4a of the frame body 4 and the holding piece 6. The scaffolding board does not fall apart.

[Effects of the Invention] As described above, in the scaffolding board 1 for construction according to the present invention,
The scaffolding plate 6 in which the upper surface edges 4a of the frame body 4 and the upper surface portion 4a of the frame body 4 are cut off from the upper surface edges 3a at both ends of the scaffolding plate single body 3
Since the scaffolding board is held between the scaffolding board and the scaffolding board, the scaffolding board single body 3 does not fall apart even if the spot welding comes off due to the impact of the keeling machine. The operating efficiency of the machine can be improved.
