Embodiment 1 An embodiment will be described below with reference to the drawings. <B> Working stage (FIGS. 1 to 3 and 13) The working stage 1 is attached to the external scaffold 7 as shown in FIG. 1 during the construction work so that, for example, the construction material is taken into the body. Provisionally. The work stage 1 mainly includes a frame body 2 that holds the floor plate, an inverted U-shaped claw portion 21 attached to a side portion of the frame body 2, a side handrail 3, a front handrail 4, and the like. The formwork 2 is provided with a reinforcing material 23.

As a method of attaching the work stage 1,
Lift it up with a crane or the like, put the inverted U-shaped claw portion 21 on the pipe beam 71 of the external scaffold 7, and use the stay 5 for the pedestal 7 of the external scaffold 7.
Hang it on 4 and fix it. The outer scaffold 7 is fixed to the wall 73 by a wall joint 72. The inverted U-shaped claw portion 21 is attached to the horizontal pipe beam 71 of the wall joint 72. Further, the stay 5 is attached to the pedestal 74 of the horizontal external scaffold 7 of the wall joint. By mounting in this way, even if a load is applied to the work stage, the work stage can be safely fixed to the external scaffold 7.

A plan view of the work stage 1 attached to the outer scaffold 7 is shown in FIG. 2, and a front view thereof is shown in FIG. The inverted U-shaped claw portion 21 is fixed to the pipe beam 71 of the outer scaffold 7 at four places. A reinforcing body is attached inside the frame body 2 to reinforce the frame body 2. The stay 5 is held by a pedestal 74 one step above the pipe beam 71 to which the inverted U-shaped claw portion 21 is attached. Alternatively, the stay 5 may be held by the stanchion 74 at the lower portion of the first stage to support the frame body 2 from below. Alternatively, instead of the stay 5, the hanging wire 6 may be held by the pedestal 74 at the upper part of the two steps. The stay 5 and the hanging wire 6 are the work stage 1
It functions as a holding material for holding. Stay 4
Has a configuration as shown in FIG. 5, and is fixed to the pedestal 74 by the clamp 51. The suspension wire 6 has a structure as shown in FIG. 6, has a turnbuckle 61, and is fixed to a pedestal 74 by a shackle 62. For convenience of description, the floor plate placed on the frame 2 is omitted. Although not shown, it is preferable to surround the upper part of the periphery of the frame body 2 with a plate to prevent an object placed on the floor from falling.

<B> Inverted U-shaped claw portion (FIG. 4) The inverted U-shaped claw portion 21 is fixed to the frame body 2 as shown in FIG. The inverted U-shaped claw portion 21 has a shape that can be easily attached to the pipe beam 71 and, as a safety measure, is provided with an external stopper metal fitting 22 so as not to come off from the pipe beam 71.

<C> Handrail (FIGS. 7 to 12) The work stage 1 is provided with a front handrail 4 and two side handrails 3 and is attached to the frame body 2 in consideration of work safety. . These handrails are foldably attached for better transportability.

As a folding method, first, the side handrail 3 is pulled up (see FIGS. 7 to 8) and folded to the front handrail 4 side. The pillar 31 of the side handrail 3 is detachably attached to the pillar holding portion 25 fixed to the frame body 2 as shown in FIG. 10 (enlarged view of A in FIG. 7). Further, the other column 31 of the side handrail 3 is attached via the front handrail 4 and the rotary sliding portion 32 as shown in FIG. 11 (enlarged view of B in FIG. 7). Therefore, the side handrail 3
Can be pulled up with respect to the frame body 2 and separated, and pulled up with respect to the front handrail 4 and can be rotated and folded toward the front handrail 4 side.

The front handrail 4 is raised with respect to the formwork,
It can be folded to the mold side (see FIGS. 8 to 9). As shown in FIG. 12 (enlarged view of C in FIG. 7), the support column 41 of the front handrail 4 is slidably and bendably attached to the supporting and retaining section fixed to the frame body 2 through the movable retaining section 42. Has been. The movable holding portion 42 has a long hole 43, is fixed to the pillar 41 of the front handrail 4, and the pillar holding portion 25 has a pin portion 44 that engages with the long hole 43. With this configuration, the front handrail 4 is pulled upward with respect to the frame body 2 and can be folded to the frame body 2 side when separated from the support holding portion.

FIG. 9 shows the state of the folded work stage. This state allows the work stages to be stacked on top of each other, which facilitates transportation. On this occasion,
The leg members 24 can be stably stacked on top.

<D> Mounting position of work stage (see FIG. 1)
3) The work stage was attached to the outer scaffold 7, the bending moment generated in the outer scaffold 7 was measured, and the position at which the work stage was safely attached was obtained. As shown in FIG. 13, the frame body 2 needs to be fixed to the pipe beam 71 which is horizontal to the position where the wall joint 72 is attached. The suspension stay 5 or the suspension wire 6 which is a holding material for holding the frame body 2 also needs to be fixed to the pedestal 74 corresponding to the wall joint 72 (FIG. 1).
3 (a)-(b)). In addition, the stay 5 that holds the frame body 2 from below also needs to be attached to the pedestal 74 corresponding to the wall joint 72 (see FIG. 13C).

[0015]

According to the present invention, the following effects can be obtained. <B> The work stage can be safely and efficiently fixed to the external scaffold by hooking the inverted U-shaped claw portion attached to the frame body on the pipe beam. <B> Since the handrail of the work stage is of a folding type, it is easy to assemble, disassemble, and carry. <C> The strength of the work stage can be obtained by setting the attachment position of the work stage to the wall joint position of the external scaffold.
