する自昇式型枠装置。(1) Consists of a lifting jacking device whose lower part is removably attached to an existing concrete wall and a formwork attached to the upper part of the jacking device. After concrete is poured into the formwork and hardened, The operations of extending the jacking device to raise the formwork, then removing the lower fixing fitting of the jacking device to shorten the jacking device, and fixing the lower part of the jacking device to a new existing concrete section are repeated. In a self-lifting formwork device for sequentially pouring concrete upward, the upper part of the lifting jack device is connected to the formwork via a cross frame, and one end of the cross frame is separated. A self-lifting formwork device, characterized in that it is connected to a mold jack so that the formwork moves parallel to a concrete placement surface when the mold release jack expands and contracts. （２）前記上昇用ジヤツキ装置が前記クロスフレームの
