  The present invention serves as a staircase, a ladder, and a scaffolding board suitable for use in building roofs, general house roof construction, repair work, hill slope work, other general construction and civil engineering work, etc. It relates to a multi-purpose stage that can be used for various purposes.

  Generally, when building or repairing a roof of a building or a general house, if the roof has a slope of an arbitrary angle, it is difficult for an operator to walk vertically and horizontally along the roof surface. The posture becomes unstable, the workability is poor, and in the worst case, there is a risk that the worker falls and falls to the ground.

  Therefore, as shown in Patent Document 1, a roof that prevents a worker from falling or falling to the ground during work while walking on the roof surface can be performed safely and prevent personal injury. Construction scaffolds have been developed.

This roof construction scaffolding includes an angle-adjustable rigid trap placed vertically on the roof surface in accordance with the slope of the roof surface, and an angle-adjustable handrail raised on one or both sides of the trap. The scaffolding plate is horizontally coupled to the side of the tarp via an adjustable scaffolding plate support bracket, and the handrail is erected on one side or both sides of the scaffolding plate. An operator walks and works.
