Description

[Detailed description of the invention] [Prior art] This invention relates to the improvement of scaffold boards for work scaffolds that are temporarily installed during the construction of structures, by eliminating protrusions and gaps on the floor boards and making it possible to check the locking state of the hooks. This is designed to be easy and improve safety.

[Conventional technology]

Scaffolding for work is often temporarily erected when constructing structures, including construction structures.

This work scaffolding is constructed by creating a scaffolding frame by combining steel bars and pipes, and then passing scaffolding boards over the horizontal scaffolding frame.

Such work scaffolding needs to be removed after the structure is completed, so it is required to be easy to temporarily set up and remove, and to be safe.

For this reason, the scaffolding board on which workers work is provided with two mounting hooks 3 welded to each end of the floorboard 2, as shown in FIG. 3, and these mounting hooks 3 are attached to the scaffold frame 4. It can be easily fixed by hanging it.

[Problem that the invention attempts to solve]

However, in the conventional scaffold board 1, as shown in FIG. 4, the mounting hook 3 attached to the end of the floor board 2 protrudes above the floor surface of the floor board 2, and the amount of protrusion H is considerable. It has become a value.

Therefore, when trying to move to the next scaffolding board 1, it is easy to trip and is very dangerous.

In addition, when the scaffolding boards 1 are arranged in succession, a gap B is created between the adjacent scaffolding boards 1 by the amount of the mounting hook 3, which is not only higher but also creates a space, so that if you step on it, Not only is this extremely dangerous, but there is also a high risk of small parts such as tools falling.

Furthermore, when transporting for construction or transporting after removal, the scaffolding boards 1 are stacked, but in this case, the mounting hooks 3
The overhang of the container is so large that efficient transportation is not possible.

This idea was made in view of the prior art, and is a temporary structure that does not create protrusions or gaps between adjacent scaffolding boards, makes it easy to check the locked state of the hook, is safe, and is easy to transport. The idea is to provide a scaffolding board.

[Means for solving problems]

In order to solve the above problem, the temporary scaffolding board of this invention has hooks that can be hung on the scaffolding frame attached to both ends of the floorboard, which will serve as the work floor, so that the upper ends do not protrude from the floorboard, and The cover plate that covers the hook is constructed of a mesh steel plate that is flush with the floor plate and allows confirmation of the locked state of the hook.

[Effect]

By attaching hooks to the floorboards that make up the temporary scaffolding so that they do not overhang upward, the working floor surface is made flat.Furthermore, a mesh steel plate cover is placed on top of the hooks to make it easy to check the locking status of the hooks. Set up a board,
The gap formed by the hook is closed to prevent it from falling.

〔Example〕

An embodiment of this invention will be described in detail below with reference to the drawings.

FIG. 1 is a partial perspective view of one embodiment of the temporary scaffolding board of this invention.

This temporary scaffolding board 10 includes a floorboard 11 that serves as a working floor surface for workers to stand on and work on, and is made of a steel plate or the like and reinforced with ribs or the like.

Two mounting hooks 12 are welded to each end of the floor plate 11, but as shown in FIG. At the same time, the mounting positions of the hooks 12 are slightly shifted in the width direction between one end and the other end so as not to interfere with the hooks 12 of the adjacent temporary scaffolding board 10.

In addition, a cover plate 13 is welded to the end of the floor plate 11 to cover the upper part of the hook 12, and has a length up to the center of the scaffolding frame 4 on which the hook 12 is hung.
It is designed not to interfere with the cover plate 13 of the adjacent temporary scaffolding board 10. As this cover plate 13,
A mesh steel plate with mesh-like holes is used, and the state of engagement of the hook 12 to the scaffolding frame 4 can be confirmed from above using the mesh portion.

The temporary scaffolding board 10 constructed as described above is attached by hooking the hooks 12 between the horizontal scaffolding frames 4.

In this state, the hook 12 does not protrude beyond the floorboard 11, so the worker will not trip over it when walking. Since the cover plate 13 is attached to cover this hook 12 portion, a floor surface is formed without any gaps, and it is possible to prevent tripping or parts from falling during work.

In addition, in this temporary scaffolding board 10, the hook 12
Since the hooks do not protrude beyond the floorboard 11, it is easy to stack them for transportation, etc., and the hooks 12 do not interfere with each other.

[Effect of idea]

As specifically explained above with one embodiment, according to the temporary scaffolding board of this invention, hooks are attached to both ends of the floorboard so that the upper ends do not protrude from the floorboard, and the hook portions are covered with a board. Since it is covered, the hook part becomes a flat surface that is the same as the floor surface, which prevents workers from tripping.
Since the floor surface is formed with no gaps, there is no chance of tripping or falling objects, improving safety.

Furthermore, when transporting temporary scaffolding boards, the hooks do not protrude above the floorboards, so they can be easily stacked and the transport efficiency is high.

Furthermore, since the upper part of the hook is covered with a cover plate made of a mesh steel plate, the locked state of the hook 12 to the scaffolding frame 4 can be confirmed from above using the mesh part, and the work can be performed more safely.

Claims (1)

[Scope of utility model registration request] Hooks that can be hung on the scaffolding frame are attached to both ends of the floorboard that will serve as the work surface so that the upper ends do not protrude from the floorboard, and a cover plate that covers this hook is placed on the same plane as the floorboard so that the hooks are locked.
