ならないという問題がある。Such a work scaffold is a temporary structure, and it is necessary to quickly install and remove the work scaffold at the start and end of construction. However, in a conventional work scaffold, a pair of frames and a brace are connected by a thumbscrew, etc., so turning work of these thumbscrews is troublesome, and it takes time to install or remove at a construction site or the like. There is a problem that it takes. In addition, conventional work scaffolds include frame, scaffolding board,
Since these members are disassembled into braces or the like, it is necessary to store these members individually, and there is a problem that a wide accommodation space must be secured.

折り曲げ可能となっていることを特徴とする。The work scaffold of the present invention is a work scaffold used as a temporary floor or aisle of a worker, and is a pair of frame bodies which are installed upright and are bridged between these frame bodies. The scaffolding plate and the connecting means for connecting the pair of frame bodies are formed, and both ends of the connecting means are rotatably connected to the pair of frame bodies and can be bent midway in the longitudinal direction. It is characterized in that.

なる。In the present invention as described above, since the pair of frame members which are erected to face each other are connected by the connecting means, they can be used as work scaffolds only by bridging the scaffold plate on the upper part of these frame members. Become. Since this eliminates the need for braces, the work of attaching and detaching the braces at the construction site is omitted, and the work scaffolds can be easily assembled and disassembled. Also, the connecting means is
Since both ends are rotatably connected to each frame and can be bent in the middle, when the frame is not used as a work scaffold, by bending this connecting means, the frames can be placed close to each other. It becomes possible to do. As a result, the frame body and the connecting means are made compact, so that a large accommodating space as in the conventional case is unnecessary.

なるため、取扱性も向上する。When the frame body is vertically expandable and contractible and the connecting means is longitudinally expandable and contractable, the frame body and the connecting means are made more compact by bringing them into a contracted state. Therefore, the storage space can be further reduced. Further, when at least one of the frame body of the pair of frame bodies and the scaffold plate is provided with an attachment means, the scaffold plate is attached to the frame body to form the scaffold plate. There is no need to secure a separate storage space, and the work scaffold is integrated as a whole, which improves handling.

In this figure, the connecting means 12 is rotatable in the vertical direction on any one of the pair of outer cylinder frames 14A of the pair of outer cylinder frames 14A facing each other in the pair of main frames 14 arranged to face each other. It is connected. In such an embodiment, in addition to the effect of the above-described embodiment, the strength of the load in the vertical direction is increased because the connecting means is erected.

スペースを削減できるという効果もある。As described above, the working scaffold according to the present invention is formed by connecting a pair of frame bodies which are opposed to each other by a connecting means, and a scaffold plate is laid over the upper portions of these frame bodies. Therefore, there is an effect that assembling and disassembling of the work scaffold can be easily performed only by detaching and attaching the scaffold plate. Further, since both ends of the connecting means are rotatably connected to the respective frame bodies and can be bent midway in the longitudinal direction, after the dismantling, the connecting means are bent so that the frame body and the connecting means can be bent. And are also compact, which has the effect of reducing the storage space.
