To provide built-up temporary stairs that are easy to assemble and disassemble with a small number of parts, can be installed and recovered in a short time, and can be disassembled for transportation and storage when not in use.SOLUTION: Stairs have left and right main body frames 12a and 12b that are detachably fixed to a scaffold post 13 by a pivotable clamps 14 at the ends, and a plurality of treads 15 that are detachably attached between the main body frames 12a and 12b, each of the main frame 12a and 12b has parallel upper 16a and 16b and lower 17a and 17b, and a plurality of connecting pieces 18 rotatably connected at one end and the other end to the inner part of the upper 16a and 16b and lower 17a and 17b, each treads 15 has a thread body 21 that has a rectangular shape from a plane view and a mounting portion 25 disposed in the lower part of the center of each short side, a tread plate mounting portion 23 is formed in which each mounting portion 25 is detachably attached in the center of the longitudinal direction of each connecting piece 18 to support each tread plate 15 horizontally.SELECTED DRAWING: Figure 1
【課題】部品点数が少なく組立及び分解が容易で、短時間で設置及び回収を行うことができ、使用時以外は分解して搬送及び保管が可能な組立式仮設階段を提供する。【解決手段】先側の回動可能なクランプ部１４により足場の支柱１３に着脱可能に固定される左右の本体フレーム１２ａ、１２ｂと、本体フレーム１２ａ、１２ｂの間に着脱可能に装着される複数の踏み板１５を有し、各本体フレーム１２ａ、１２ｂは平行配置された上辺部１６ａ、１６ｂ及び下辺部１７ａ、１７ｂと、一端側及び他端側が上辺部１６ａ、１６ｂ及び下辺部１７ａ、１７ｂの内側部に回動可能に連結された複数の連結片１８を有し、各踏み板１５は平面視して長方形状の踏み板本体２１と、その各短辺の中央下部に設けられた装着部２５を有し、各連結片１８の長手方向の中央部に各装着部２５が着脱可能に装着されて各踏み板１５を水平に支持する踏み板取付部２３が形成されている。【選択図】図１
