To provide a scaffold having a height and a scaffold dimension allowing an evacuee to easily get over a guard rail, observing the construction limit of a roadway in a normal time, and facilitating evacuation from the roadway side to the roadside in evacuation.SOLUTION: A climbing scaffold 3 is provided with a roadway side scaffold 3a, a roadway side scaffold 3b, and a handrail support 4, and is supported by a U-shaped support member 30 mounted in parallel to a beam 22 on the roadside of the column 21 of a guard rail 2 and in a cantilever state on the column at the lower position of the beam. The roadway side scaffold is rotatably connected to the U-shaped support member and is, in normal times, stored in a lower space of the beam by a middle folding rotation part 3123 of a diagonal member 312, and when retreating, the middle folding rotation part of the diagonal member is extended and fixed to form the roadway side scaffold at a lower position of the beam on the roadway side. The roadway side scaffold is fixed to the U-shaped support member at a position below the beam, and the handrail struts are fixed to the U-shaped support member and formed on both outer sides of the roadway side scaffold.SELECTED DRAWING: Figure 1
【課題】退避者が容易にガードレールを乗り越えられる高さと足場寸法を有し、通常時は車道の建築限界を遵守し、退避時は車道側から路側側への避難が容易な足場を提供する。【解決手段】乗り越え足場３は、車道側足場３ａと、路側側足場３ｂと、手摺支柱４と、を備え、ガードレール２の支柱２１の路側側にビーム２２に平行にかつビームの下方位置において支柱に片持ち状態で取付けられたコ字状支持部材３０により、支持されている。車道側足場は、コ字状支持部材に回動可能に連結され、通常時には、斜材部材３１２の中折れ回動部３１２３により、ビームの下方空間に収容され、退避に際しては、斜材部材の中折れ回動部を伸展固定して、車道側にビームの下方位置にて車道側足場を形成する。路側側足場はコ字状支持部材に、ビームの下方位置にて固定され、手摺支柱はコ字状支持部材に固定されて、車道側足場の両外側に形成される。【選択図】図１
