で引き上げ、そして、柱型枠の上方からコンクリートを
注入してコンクリートを打設するようにしていた。(Prior Art) Conventionally, when constructing columns for an RC super high-rise system, a scaffold is assembled to the upper part of the column formwork, a hose is pulled up to above the column formwork, and concrete is fed from above the column formwork. It was pouring and pouring concrete.
（発明が解決しようとする問題点） ところが、鉄筋コンクリート建築の柱型枠内には多数の
鉄筋が埋め込まれており、場合によっては鉄骨も埋め込
