In the construction of a building, it is desirable that not only the entire construction period but also the construction period of each part is as short as possible. In particular, the stairway structure makes it impossible to pass through that part during construction, which hinders the progress of other construction. Therefore, it is strongly required to shorten the construction period on site as much as possible. In addition, since the removed formwork cannot be diverted and will be incinerated, if the formwork used for stair construction can be reduced even a little, part of the formwork removal work can be omitted and the construction period can be shortened. Not only can they contribute, but they can be useful for resource conservation.
