To provide an expansion/contraction guide member for a shoring, an expansion/contraction device for the shoring, an expansion/contraction shoring, a method of expansion/contraction of the expansion/contraction device for the shoring, and an expansion/contraction method of the shoring, which can be easily applied to vents of various shapes, can use a general-purpose jack, and can be constituted at a low cost.SOLUTION: An expansion/contraction guide member 12 for shoring is provided with a jack 30 capable of being extended/contracted in a fixed direction and is constituted so as to be extended/contracted in the fixed direction by the extension/contraction of the attached jack 30; the extension/contraction guide member 12 for shoring has a main body part 12A, which can extend/contract in the fixed direction, having a mounting part for mounting a jack 30; and a lock mechanism 16, which is provided in the main body part 12A and can switch between a restriction for preventing the main body part 12A from contracted below a predetermined length in the fixed direction and the release of the restriction, and the locking mechanism 16 allows repositioning of the load in the direction of contraction of the jack 30 between the jack 30 and the main body part 12A.SELECTED DRAWING: Figure 1
【課題】様々な形状のベントに適用させやすく、また、汎用型のジャッキが使用可能で低コストに構成することができる支保工用伸縮ガイド部材、支保工用伸縮装置、伸縮支保工、支保工用伸縮装置の伸縮方法および支保工の伸縮方法を提供する。【解決手段】一定方向に伸縮可能なジャッキ30が取り付けられ、取り付けられたジャッキ30の伸縮により前記一定方向に伸縮可能に構成された支保工用伸縮ガイド部材12であって、支保工用伸縮ガイド部材12は、ジャッキ30を取り付ける取り付け部を有する前記一定方向に伸縮可能な本体部12Aと、本体部12Aに設けられ、本体部12Aが前記一定方向に所定長さ以下に収縮しないようにする制限と前記制限の解除を切り替え可能なロック機構16と、を有し、ロック機構16によりジャッキ30と本体部12Aとの間でジャッキ30の収縮方向の荷重の盛り替えを可能にした。【選択図】図1
