Description

[Detailed description of the invention] The invention consists of a hanging frame, a horizontal rod, a joint rod,
The present invention relates to a scaffolding device that is equipped with a scaffolding board and that can easily and safely form a scaffold below the horizontal members of a frame structure.

When a frame structure of a building is erected, scaffolding is often provided below the horizontal members for bolting, painting, and passage. Conventionally, this kind of scaffolding has been constructed by circling and suspending a chain around a horizontal member with the end heights aligned, and then horizontal members such as steel pipes are spanned over the chain, and then scaffolding boards are erected between the horizontal members. However, since it uses a chain,
It is necessary to span horizontal members at both ends of the chain at the same time, which results in poor work efficiency such as the need for multiple workers, and furthermore, the chain and horizontal members are prone to slipping, which poses a danger to the scaffolding work. Furthermore, since chains are used, pitching, rolling, etc. are likely to occur, making it difficult to form a stable scaffold.

The present invention aims to provide a scaffolding device (hereinafter referred to as the device) that can solve these problems, and one embodiment thereof will be described below based on the drawings.

In the drawings, the device 1 of the present invention includes a hanging frame 2,
The hanging frame 2 comprises long horizontal rods 3, 3, a connecting rod 4, and a scaffolding board 5, and side rods 10, 10 hang down at an incline slightly spreading downward on both sides of a base rod 9 that straddles the upper flange of a horizontal member 7 of the framework structure A, for example made of H-shaped steel, and the lower ends of the side rods 10 are provided with hook portions 11, 11 that are bent inwardly into an approximately U-shape, and the hanging frame 2 is formed by bending a steel bar. In addition, at the corner between the base rod 9 and the side rod 10, both side edges of the upper flange of the horizontal member 7 are welded to the corner, with anti-sway pieces 12, 12 made of angle iron located at the inside corner perpendicular to the base rod 9. Therefore, by attaching the hanging frame 2 to the horizontal member 7, it is possible to regulate not only the lateral movement perpendicular to the horizontal member 7, but also the longitudinal, i.e., vertical, movement of the hanging frame 2, and the hanging frame 2 is juxtaposed to the horizontal member 7 at an appropriate interval.

The horizontal rods 3 are made of long steel pipes that can be fitted into the hook portions 11, and are located on each side of the hanging frames 2 that are juxtaposed, and each hook portion 1 is arranged in a straight line parallel to the horizontal member 7.
The horizontal rods 3 and 3 are arranged horizontally and in parallel by being spanned between the rods 1 and 11, respectively. joint rod 4
The locking portions 16, 16 are formed by bending a flat plate at both ends of the horizontal rod 14 into an inverted U shape into which the horizontal rod 3 can be inserted.
The horizontal rods 3, 3 can be connected by the locking portions 16 engaging with the horizontal rods 3, respectively, and the connecting rods 4 are arranged in a plurality in parallel between the horizontal rods 3, 3. By providing this, the scaffolding board 5 can be placed on the horizontal beam 14. The scaffolding board 5 is a bent body of a plate or steel plate, and includes a protruding piece 17 into which the horizontal rod 14 can be inserted,
17 is swollen on its lower surface.

However, in the scaffolding device 1 of the present invention, as described above, the hanging frames 2 are arranged side by side on the horizontal member 7, and the horizontal rods 3, 3, which are spanned over the hook portions 11 on each side thereof, are connected by the joint rods 4. On the other hand, the scaffolding device 1 is formed by placing the scaffolding board 5 on the horizontal beam 14, and the hanging frame 2 is provided with anti-swaying pieces 12 to prevent vertical shaking and Hanging frame 2
Since it is made of bar steel, there is no inclination or positional shift of the hanging frame 2 even when the horizontal rods 3 are sequentially attached to each hook 11, and the scaffolding device 1 can be assembled by a single worker. sell.

As described above, the scaffolding device of the present invention includes a hanging frame, a horizontal rod, a joint rod, and a scaffolding board, and can be easily and quickly used under the horizontal members of a frame structure using a conventional chain. Unlike scaffolding, one worker can safely assemble the scaffolding.
Efficiency and safety can be improved in erection work of frame structures, such as bolting work of horizontal members. In addition, in the scaffolding device of the present invention, it is possible to further reduce slippage with the horizontal rod by attaching a friction material such as rubber to the hook portion, the locking portion, etc. The scaffolding device of the present invention can be modified in various ways, such as by forming a recessed portion and using a so-called clamp that is fixed by clamping pressure as a locking portion.
