That is, the support frame 210 fixes the third connection bracket 218 to one side of the pillar frame 110 , and a plurality of first support bars 212 are configured on the other side of the third connection bracket 218 . The intermediate support bar 216 is fixed between the plurality of first support bars 212 by a fourth connection bracket 219 to exert a reinforcing force, and the end of the first support bar 212 is By fixing the second support bar 214 to the part, the frame of the support frame 210 is formed.

Then, the footrest 260 is fixed on the support frame 210 .

At this time, since an opening is formed on one side of the footrest 260, the door unit 230 is mounted on the opening to ensure that the operator enters and exits the work space, and any fall of the operator through the opening is prevented. to prevent

That is, the door part 230 fixes the door rail 238 to one side of the first support bar 212 in which the opening is formed with the rail fixing bracket 239 .

Then, by inserting a plurality of casters 234 fixed to the lower end of the opening and closing plate 232 spaced apart from each other into the door rail 238, the opening and closing plate 232 is transported along the door rail 238, The opening of the footrest 260 is opened and closed by the opening/closing plate 232 .

In addition, the safety handrail 220 is configured above the support frame 210 on which the door part 230 is mounted.

The safety handrail 220 fastens a fifth connection bracket 225 to one side of the first support bar 212 of the support frame 210, and is fixed in the support frame 210 by the fifth connection bracket 225. A plurality of vertical frames 221 having a height are fixed, and the first to third frame frames 222, 223, and 224 are sequentially formed from the bottom to the top at regular intervals along the longitudinal direction of the vertical frame 221. It is fixed by the sixth connection bracket (226).

Then, a plurality of handrails 228 are fixed between the first and second frame frames 222 and 223 by fastening means to form a working space.

In addition, in order to strengthen the reinforcing force for the support frame 210 and the safety handrail 220, an upper reinforcing rib 240 is formed between the upper end of the pillar frame 110 and the safety handrail 220, and the pillar A lower reinforcing rib 250 is formed between the lower end of the frame 110 and the supporting frame 210 .

On the other hand, when the plurality of working space units 20 are formed on the pillar 10 , the door units 230 configured in each of the plurality of working space units 20 are not positioned on the same axis, but are configured alternately. It is preferable to

What has been described above is only one embodiment for implementing the prefabricated aerial work platform, and the present invention is not limited to the above embodiment. Those of ordinary skill in the art to which the present invention pertains will understand that various modifications can be made without departing from the gist of the present invention.
