【Example】

 An aerial work platform according to an embodiment of the present invention will be described below with reference to the drawings.

As shown in FIG. 1, the aerial work platform 1 of the present embodiment comprises post members 4 attached to the side surfaces of a scaffolding plate 2, and handrails 5 attached to the post members 4.

As shown in FIGS. 2 and 3, the post member 4 has a cylindrical socket 8 into which the lower end portion of the handrail 5 is inserted, and an engaging portion which engages with the scaffold plate 2 at an appropriate position. And 10 are provided.

As shown in FIG. 3, the engaging portion 10 is sandwiched between plate-like members 12 and 13 fixed in parallel between the upper portions of two side plates 11 and the plate-like members 12 and 13. Nut 15 and a bolt 16 penetrating the plate-shaped members 12 and 13 and screwed into the nut 15, a knob 17 fixed to the tip of the bolt 16 for rotating the bolt 16, and a bolt 16 of the bolt 16. A moving member 18 that is attached so as to be movable in the axial direction of the bolt 16 from the head side, and a fixed plate 19 that is fixed to the lower part of the side plate 11 and holds the peripheral edge of the scaffold plate 2 between the moving member 18. And a locking piece 14 that is welded to the moving member 18 and locks the moving member 18 to the bolt 16.

As shown in FIG. 1, the handrail 5 has a small-diameter pipe 5b inserted into a large-diameter pipe 5a so that the handrail 5 can expand and contract in the width direction. When the handrail 5 is moved along the scaffolding plate 2, the handrail 5 can be expanded and contracted correspondingly.

According to the aerial work platform 1 of this embodiment, the post member 4 is provided with the engaging portion 10 thereof facing the scaffold plate 2, and the peripheral edge of the scaffold plate 2 is composed of the fixed plate 19 and the movable member 18. By sandwiching and rotating the knob 17 to project the bolt 15, the peripheral edge of the scaffolding plate 2 is held between the fixed plate 19 and the movable member 18. The lower end of the handrail 5 is mounted and attached to the socket 8 of the post member 4. Here, when the structure interferes with the handrail 5, the post member 4 is moved along the scaffolding plate 2 so that the handrail 5 does not interfere with the structure, and the movable member 18 and the fixed plate 19 of the post member 4 are moved again. The scaffolding board 2 is clamped by and the post member 4 is attached to an arbitrary position of the scaffolding board 2. Therefore, even if it is necessary to move the position of the handrail 5 due to the relationship with the structure, the handrail 5 can be attached at an appropriate position without forming a gap through which a person can pass. As a result, it is possible to greatly improve the safety of high-place work in the field of building construction.

Next, another embodiment of the present invention will be described with reference to FIG. This is a post member 25 in which a convex strip 21 is formed on the side surface of the scaffolding plate 20, a socket 22 is formed in the upper portion, and a leg portion (engaging portion) 23 having a U-shaped cross section is formed in the lower portion. The legs 23 are attached so as to straddle the ridge 21. A bolt 24 is screwed through the side surface of the leg portion 23.

In this structure, the bolt 24 is loosened, the leg portion 23 is moved along the ridge 21 of the scaffolding plate 20, and the bolt 24 is screwed in at an appropriate position to fix the leg portion 23, Insert the lower end of the handrail 5 into the socket 22. Therefore, the leg portion 23 can be moved according to the relationship with the structure, and it is possible to prevent a gap between the structure and the handrail 5 from being able to pass by a person.

Next, still another embodiment of the present invention will be described with reference to FIG. In this structure, a reinforcing portion 31 is formed along the length direction of the scaffolding plate 30, and a plurality of through holes (recesses) 32 are formed in the reinforcing portion 31 at intervals along which the person cannot pass. Are formed. Further, a socket 34 into which the lower end portion of the handrail 5 is inserted is formed, a leg portion (engaging portion) 33 is formed in the lower portion, and a side portion engages with the peripheral edge portion of the through hole 32. A post member 36 having a flange portion 35 is attached by inserting the leg portion 33 into the through hole 32.

Also in this case, when it is necessary to move the handrail 5 due to the interaction of the structures, the post member 36 is removed from the through hole 32, and a suitable one of the plurality of through holes 32 is provided. Transfer to the through hole 32. Since the through-holes 31 are provided at intervals so that humans cannot pass through them, there is no space for humans to pass between the handrails and the structure even if they are moved.

In each of the above-described embodiments, the sockets 8, 22, 34 and the lower portion of the handrail 5 are formed of square pipes. However, at least the lower portion of the handrail 5 has a circular outer peripheral surface. It goes without saying that pipes may be used and correspondingly round pipes may be used for the sockets 8, 22, 34.

[0020]

[Effect of the device]

 As described above, according to the aerial work platform according to claim 1 of the present invention, a post member is attached to the scaffold plate, and a handrail is attached to the post member. According to the aerial work platform according to claim 2 of the present invention, the scaffold plate is formed with a ridge, and the post member is provided. The engaging portion of the present invention comprises a leg portion having a U-shaped cross-section that straddles the ridge, and according to the aerial work platform described in claim 3 of the present invention, the scaffolding plate is provided with an interval where humans cannot pass. Since the plurality of recesses are formed and the engaging portion of the post member is composed of the leg portion into which the recess is inserted, the post member can be engaged and attached at an appropriate position of the scaffolding plate, and thus the structure Even if the handrails are moved due to the relationship with objects, there is no space for humans to pass through. Therefore, it is possible to improve safety in high-place work.
