Claims

[Claims for Utility Model Registration] A ladder for wall work that is installed on a wall and used as a scaffold for working on the wall, which is placed astride the upper end surface of the wall, It has a top base equipped with a running means that can run along the end surface, and a bar for resting the feet of the work tool, and is connected to each other via connecting parts provided at the upper and lower ends to form a ladder. and a plurality of ladder units that are suspended along the wall by connecting a connecting portion at the upper end to a connecting portion provided at a side of the top base, and a ladder unit through which the worker can pass through. A plate-like scaffolding plate is hinged and placed on a frame body which has a large size and is detachably connected to the ladder unit, and is pivotable up and down so as to open and close the inside of the frame body. The connecting portion between the ladder units and the connecting portion between the top base and the ladder unit are provided with a connecting piece provided at the lower end of the top base and the ladder unit, and a connecting piece provided at the upper end of the ladder unit. A ladder for wall work, characterized in that it is comprised of a connecting piece that is removably engaged with the unit by rotating the unit up and down, so that the ladder unit cannot fall off when the ladder unit is suspended.
