ンクリート壁の両側から立て掛けていたため、固定して
も不安定であった。また、壁の上端部では安定した平面
部を構築することが難しかった。However, since the ladder is leaned against both sides of the concrete wall as in the prior art, it is unstable even if the ladder is fixed. In addition, it was difficult to construct a stable plane at the upper end of the wall.
【０００５】また、地中梁やケーソンは壁間の面積が狭
かったり、梯子の掛止角度が限定され、場所によっては
安全に使用できない課題があった。[0005] In addition, underground beams and caissons have a problem that the area between the walls is small or the angle at which the ladder is hooked is limited, so that they cannot be used safely in some places.
【０００６】また、垂直に近い角度で梯子を掛止する場
合も、踏み部分が踏み棒では作業者が不安定になり危険
性が高いという問題点があった。[0006] Also, when the ladder is hung at an angle close to the vertical, there is also a problem that the worker becomes unstable when the stepping portion is a treadle and the danger is high.

かった。In particular, when installing a ladder in a narrow and limited space such as a construction site such as an underground beam or a caisson, it is necessary to suspend the ladder at a right angle, and a gentle slope allows a worker to work safely. Various subtle angles have been required, such as when it is desired to use. Therefore, in such a construction site, conventionally, it was necessary to use a plurality of ladders in order to improve safety.
