PROBLEM TO BE SOLVED: To provide a new improved prefabricated scaffolding that can prevent a fall of a handrail member, and to provide the handrail member.SOLUTION: The prefabricated scaffolding includes: a plurality of stages of vertical frames juxtaposed spaced from each other by a first length; scaffolding boards for connecting the two adjacent vertical frames; and a handrail member having connection parts on both sides in a longitudinal direction and connected to the two adjacent vertical frames by the connection parts. A connected position of the handrail member and the vertical frame is a position higher by a second length than the scaffolding board, and a length from the connection part on one side of the handrail member to the other side end is not shorter than the length of a hypotenuse of a right-angled triangle having a side with the first length and a side with the second length. |
