To provide a simply-structured jack-up tool capable of eliminating the necessity of bringing-in or recovery for each replacing work of a vibration-proof member.SOLUTION: The jack-up tool is provided with, for example, a first screw member, a second screw member, and a support plate. The first screw member can be disposed on an upper surface of a frame member that supports a floor member of an elevator with a vibration-proof member therebetween. The second screw member can be engaged with the first screw member and can abut against a lower surface of the floor member. The support plate can turn with the first screw member as a pivot, and can be engaged with one of the vibration-proof member, the floor member, and the frame member.SELECTED DRAWING: Figure 6
【課題】防振部材の交換作業ごとの持ち込みや回収を不要にできるシンプルな構造のジャッキアップ治具を提供する。【解決手段】実施形態のジャッキアップ治具は、例えば、第1ねじ部材と、第2ねじ部材と、支持プレートと、を備える。第1ねじ部材は、エレベータの床部材を防振部材を挟んで支持するフレーム部材の上面に配置可能である。第2ねじ部材は、第1ねじ部材と螺合可能で床部材の下面に当接可能である。支持プレートは、第1ねじ部材を旋回軸として旋回可能で、防振部材、床部材、フレーム部材のいずれかと係合可能である。【選択図】図6
