【Example】

 FIG. 1 is a partially omitted front view of a mobile scaffold showing an embodiment of the present invention, and FIG. 2 is a plan view thereof. In both figures, 1 is a scaffold, which is a pair of building frames 3 and 3'standing along a wall surface 2 of the building at a predetermined interval, and a stage 4 which is vertically movable between these building frames. It is equipped with Since the building frames 3 and 3'have the same structure except that they are symmetrical, the structure of the building frame 3 will be described below, and the description of the structure of the building frame 3'is the same. Will be omitted by adding a dash.

The building frame 3 has four pillars 5, and a plurality of stages of cloth frames 6 with plates are provided between the pillars at predetermined intervals. A stairway 7 is installed in the half of each plate-equipped cloth frame 6 so that an operator can move between the lower plate-shaped cloth frame 6 and the upper plate-shaped cloth frame 6.

Both ends of the stage 4 are suspended by wires with a suspending tool (not shown), and the suspending tool is attached to a hoist 11 provided on the top of the building frame 3 via a chain 12, and the hoist 11 is By pushing a switch (not shown) installed on the ground, it can be raised and lowered while maintaining a horizontal state. A guide rail 14 is provided upright on the stage side of the building frame 3, and guides the front and rear surfaces of both ends of the stage 4 when moving up and down. 23 is a handrail of stage 4.

In FIG. 2, reference numerals 25 and 25 ′ are wall connecting members that connect the building frame 3 and the wall surface 2 of the building, and each wall connecting member 25, 25 and 25 ′, 25 ′ has a pair of reinforcing members 33, 33 is substantially X-shaped when seen in a plan view, and the intersecting portions are connected and fixed by hinge pins (not shown).

On the back surface of the stage 4, slide members 35 are housed in a box 36 at predetermined intervals in the length direction, and are arranged so as to be slidable in the horizontal direction toward the wall surface 2 (FIG. 3). A cushion member 37 is attached to the tip of the slide member 35. A plurality of narrow strips of light weight iron plates 38 are attached to the tip of the slide member 35 and are joined together in a partially overlapped manner. The slide member 35 is slid toward the wall surface 2. When it is extended, the iron plate 38 located on the stage 4 is gradually dragged to cover the gap between the stage 4 and the wall surface 2 as shown in FIG. The iron plate 38 is divided into a plurality of pieces in the lengthwise direction of the stage 4, and it is possible to use not only all but any ones as needed. A stopper pin 40 is provided at a position where the slide member 35 is extended to a predetermined length, and is inserted into a hole (not shown) provided in the slide member 35 from a hole of a fixing member (not shown) so that the slide member 35 can move back to the box 36. I try not to.

Next, the operation of the above embodiment will be described. For example, when performing work such as painting on the wall surface 2 on the stage 4, the worker first slides the slide member 35 from the state housed in the box 36 toward the wall surface 2 and extends the tip of the slide member 35 before the work. The cushion material 37 is positioned so as to contact the wall surface 2. By the extension of the slide member 35, the iron plate 38 connected at the tip is gradually dragged from the stage 4, and covers the gap between the stage 4 and the wall surface 2. After that, the stopper pin 40 is inserted into the hole of the slide member 35 so that the slide member 35 does not suddenly come back to the box 36. As a result, the pre-work is completed and the work such as painting is to be performed. However, the excess paint of the paint sprayed on the wall surface 2 by the worker above the position where there is the gap may bounce off the wall surface 2 or work. Even if a tool used by a person falls carelessly or a part of the wall surface 2 falls, it is caught by the iron plate 38 covering the gap. When the work is completed, the worker reverses the above work, pulls out the retaining pin 40, and then causes the slide member 35 to back and accommodate it in the box 36.

FIG. 4 shows another embodiment of the covering body which replaces the iron plate 38. FIG. 4A shows a cloth or a net 42 whose tip is attached to the tip of the slide member 35 like the iron plate 38. Also in this case, when the slide member 35 is slid toward the wall surface 2 and stretched, the cloth or the net 42 is gradually dragged from the wound state on the front portion of the stage 4 on the wall surface 2 side, for example. And cover the gap between the stage 4 and the wall surface 2. In (B), a fiber reinforced plastic (FRP) plate 44 is slidably provided on the back surface of the stage 4. Further, in (C), a rigid urethane foam plate 46 is slidably provided on the back surface of the stage 4. The FRP plate 44 of (B) and the urethane foam plate 46 of (C) are not connected to each other like the iron plate 38, but are made of one plate. Further, in these cases, the slide member 35 and the like are unnecessary.

[Effect of the device]

 According to the first aspect of the present invention, the cover is provided on the stage so as to cover the gap between the stage and the wall surface of the building and receives the falling object so as to be slidable toward the wall surface of the building. It is possible to effectively prevent tools used by workers, a part of the wall surface of the building, excess paint, etc. from falling through the gap. Therefore, it is much safer than the conventional one. The invention of claim 2 can prevent the wall surface from being damaged by the cushion material when the covering is slid toward the wall surface and extended. According to the invention of claim 3, any one of a lightweight iron plate, a cloth, a net, a fiber reinforced plastic plate, and a rigid urethane foam plate can be selected as the cover. The invention of claim 4 can use only the covering at the wall surface position required, which is particularly effective when the stage is long.
