In general, when the construction, renovation, and cleaning of the building to install a work scaffold that can work according to the height, the operator can step on the installed work scaffold to climb on it to perform the necessary work.

Article 439 of the Regulation on Industrial Safety and Health Act, Industrial Safety Standards, requires employers to install work scaffolding by assembling scaffolding, etc., when a worker is at risk of falling while working at a place of more than 2 meters. Doing.

The working scaffold is normally installed so that both sides are securely supported by scaffolds installed at regular intervals on the outer wall side of the structure. The horizontal members in the horizontal form are fixed with a plurality of hooks, and the braces are installed in the diagonal direction between the vertical members and the horizontal members to sufficiently endure the lateral forces acting in the horizontal direction.

The working scaffold that is hung between the horizontal members of the scaffold has a hook that has an open shape at the bottom of both sides of the scaffold frame formed of a rectangular cross section, and an anti-slip protrusion on the front side of the scaffold to prevent the worker from slipping. It is configured to form drainage grooves to prevent rain or rain.

The working scaffold, which is caught between the two ends by horizontal hooks, is installed in such a way that it extends in the horizontal direction along the horizontal members.

In general, the essential function that the working scaffold constituting the scaffold as described above is safety, and other ease of installation and dismantling, mobility of logistics is required.

In general, the working scaffold has a width of 30 ~ 50 ㎝ in the form of an elongated plate is formed with irregularities and holes for light weight and slipping, and drain holes are formed to prevent slipping in rain water.

Hanging hooks are attached to both sides of the working scaffold, and the working scaffold can be fixed by mounting the working scaffold on the bar installed on the outer wall of the building.

Looking at the conventional hook is a support piece for fixing the hook-type hook portion and the footrest is used to be fixed to the working footrest using a total of four support pieces to each corner portion of the working footrest.

However, the conventional hook has a safety problem that is released in the event of a sudden impact load from the top or impact from the bottom to the top.

Therefore, in recent years, the working scaffolding is fixed to the scaffold by hook-shaped hooks, such a working scaffolding hook is fixed to the side end of the working scaffold, and the open end is formed at the other end, It is composed of a main hook fixed to two pins on one side of the opening and a secondary hook formed with a vertical hole and a horizontal hole to be rotatable on the two pins.

Therefore, when fastening the hook to the scaffold frame and installing the work scaffold on the scaffold, the auxiliary hook of the hook is rotated so that the opening of the main hook is opened to the maximum so that the scaffold frame is seated in the opening. The auxiliary hook was rotated again so that the structural frame of the scaffold was not detached, so that the hook could be easily installed on the scaffold.

And, when removing the working hook from the scaffolding and dismantling the working scaffold from the scaffold frame, the auxiliary hook of the working hook is rotated again to open the opening of the main hook to the maximum, and then lifting the working scaffold By separating the hooks from the structural frame, it was possible to dismantle the platform.

At this time, in order to lift the working scaffold to the upper part, it may be possible only by lifting the working scaffold with the other hand while holding the auxiliary hook with one hand, so that at least two persons to separate and dismantle the working scaffold from the scaffold. This could be possible only by lifting the working platform at the same time while holding the auxiliary hook in a group.

Accordingly, there is a lot of inconvenience in dismantling the scaffolding of the scaffold from the scaffolding and the cost increases as a lot of manpower is mobilized, there was a problem that is not economic.

In addition, two or more workers should be separated and dismantled as described above. On the site, one person, not two or more workers, separates and dismantles the work by forcibly tearing away the material by force. There was a problem that breakage occurs frequently.

On the other hand, since the work scaffold is installed in various places of the construction site and serves as a convenient passage for the construction site workers to transport various construction materials, the scaffold frame is bent or twisted due to the frequent movement of workers and other extensions and the weight of materials. There is a problem that workers feel anxiety when moving the work platform due to difficulty in maintaining the horizontal level, and in order to improve these problems, the work platform is thickened or two or three reinforcing bars are installed. .

In addition, there is a gap between the working scaffolds in order to continuously connect the working scaffolds which are installed in a continuous form in the horizontal direction along the horizontal materials by hanging both ends between the horizontal members by the hooks. Problems such as falling accidents caused by falling objects such as falling wheels of mobile equipment or falling of work tools, sand, nails, etc. There was.
