Description

  The present invention relates to a scaffold device on an inclined roof on which various building members or members such as photovoltaic power generation panels can be safely and efficiently attached and constructed on a metal inclined roof.

  Conventionally, a ladder is simply installed along a slope in a construction for attaching various members for construction or a member such as a photovoltaic power generation panel on a metal sloped roof. In this case, a light member can be safely installed. However, in the case of a member having a relatively large area or a member having a heavy weight, there is a serious disadvantage that a mere inclined ladder is dangerous.

  Further, in Patent Document 1 (Japanese Patent Laid-Open No. 8-218582), a roof scaffold is disclosed. On a roof surface that is a concave surface, serial ladders 11, 12, 13 along the roof surface are disclosed. Are provided in two rows, the scaffolding plate support device 2 is provided at a desired position, and the scaffolding plate 7 is temporarily installed between the two scaffolding plate support devices 2 and 2 on the left and right sides. In Patent Document 1, there are many drawbacks such as many constituent members, complicated and troublesome operation. Further, in Patent Document 2 (Japanese Patent Application Laid-Open No. 10-131444), a ladder device including a connecting member 23 having a ladder-like flexibility, a step member 22 (stepping platform), and a stepping plate 51 is quite complicated. There were also problems such as construction taking time.
