Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a work stage used at a construction site or the like.

[Conventional technology]

In the finishing work of construction, a lot of work at high places in the room is required due to construction of the ceiling base, installation of the ceiling board, and other painting work.

Therefore, a working stage is used.
As shown in the figure, 1 in the figure is a caster 2 with a brake at the lower end.
The columns 1 are connected to each other by the horizontal connecting members 3a, 3b, 3c in upper and lower stages to form the stage frame 4.

The stage frames 4 are arranged side by side at intervals and are connected by cross braces 5, and further, a stage cloth plate (scaffolding plate) 6 is bridged between the uppermost horizontal connecting members 3c.

This stage cloth plate (scaffolding plate) 6 is the same as the cloth plate used in a normal frame scaffold, and has a hook at the end thereof, and the hook is hooked on the lateral connecting member 3c to be locked.

By the way, it is desirable that the height of the stage cloth plate 6 can be changed due to the difference in working place and the height of the worker.

Therefore, in the example of FIG. 7, the support column 1 is an extendable support column formed by connecting the inner tube and the outer tube, and the entire stage frame 4 is vertically extended and contracted.

In such a work stage, the casters 2, the stage frame 4, the cross braces 5, and the stage cloth plate 6 can be separated from each other. When used, the members are assembled into a stage, and when not used, the members are assembled. Separate and store.

If the support column 1 is a telescopic column, the inner tube and the outer tube will be fixed with the insertion pin, but since strength instability remains, this is not used as the telescopic column, and the horizontal connecting member 3a, 3b, 3c
If the width of the stage cloth plate 6 is wide enough to be hung from a plurality of stage cloth plates 6 (for example, 3 pieces), and the stage cloth plates 6 are laid one by one from the horizontal connecting members 3a in the lower step, This stage cloth plate 6 is arranged in a stepwise manner and can be adapted to several heights.

To do this, the lower row of lateral ties 3a are located higher.

[Problems to be solved by the device]

As shown in FIG. 7, in the case where each member is stored separately, it takes time and labor for assembling and disassembling, and management of the separated members is troublesome.

Therefore, as in Japanese Patent Application No. 2-27456, stage frame 4
There is also one that connects each other with a stretchable tie and shrinks this tie when not in use so that they overlap, but this stretchable tie interferes with the lower step of the stage frame 4. The stage cloth plate 6 cannot be hung on the horizontal connecting members 3a and 3b.

The object of the present invention is to eliminate the inconvenience of the above-mentioned conventional example, and even when a stage cloth plate is hung over a plurality of connecting members in a stepwise manner, it can be folded easily and reasonably, and can be stored and assembled. It is to provide a work stage that can be performed easily.

[Means for Solving the Problems]

In order to achieve the above-mentioned object, the present invention forms a stage frame by connecting columns to each other with a plurality of upper and lower horizontal connecting members, and transfers the stage frames that are arranged in parallel with each other to the horizontal connecting members. In the work stage that is connected by a plate, the horizontal connecting material has a width that allows a plurality of stage cloth plates to be lined up and hung.
The stage frame has a plurality of upper and lower horizontal connecting members, one end of which is fixedly coupled to one of the columns, and the other end of which is rotated with respect to the other column via a hinge bracket provided on the column. The stanchions that are freely pin-connected and rotatably connected to this horizontal connecting member are fixedly connected with the connecting beam member at the lower part between the stage frames, and the upper part is one end of the stage cloth plate that is hung between them. From the other side end of the stage cloth plate is detachably supported by the uppermost horizontal connecting member. Further, a bracket is provided, and the pin connecting portion of the hinge bracket to the horizontal connecting member is located outside the surface of the stage cloth plate when the vertically arranged stage cloth plate is hung over the columns of the left and right stage frames. To project horizontally from the column It is an gist and.

[Action]

According to the present invention, the stage frame can be folded into a double door type door with a pillar that pivotally connects with a horizontal tie member as an axis. Is fixedly connected with each other, and is fixedly connected at one end in the longitudinal direction of the stage cloth plate at the upper portion, but this stage cloth plate is connected by a pin and is projected from the other one end. When the pin is removed from the pin receiving bracket provided on the lateral connecting member, the pin is rotated in the vertical direction.

Therefore, tilt the stage cloth plate slightly upward with the connecting pin connection as the axis, and remove the pin on the other side from the pin receiving bracket,
In addition, the stage frame can be folded vertically when the stage frame is pushed slightly outward with the support post pivotally connected to the horizontal tie as an axis.

In this way, the stage cloth plate can be folded first, and then the stage frame can be folded inward so as to overlap with the stage cloth plate about the pillar that pivotally connects the stage frame and the lateral connecting member.

Further, in addition to the above-mentioned action, other stage cloth plates are vertically aligned with the stage cloth plate that has been previously folded, and are vertically stretched between the lateral connecting members of the stage frame and the columns that are rotatably connected to each other. However, even when a plurality of stage cloth plates are stored vertically side by side in this way, the pin connection part of the hinge bracket provided with the columns to the horizontal connecting member is located outside the surface of the stage cloth plate. The stage frame can be folded inward so as to be overlapped with these stage cloth plates, and the stage cloth plates removed from the lateral tie members can all be housed inside to bring the whole into a compact state.
