JACK DEVICE
To provide a jack device that easily and accurately detects the amount of its own sinking amount.SOLUTION: A jack device 11 comprises: a jack main body 2 arranged between a building 91 and a ground 92 and consisting of a lower part 21 having a placement surface 211 placed on a ground surface 921, and an upper part 22 having a support surface 221 to be raised and lowered relative to the lower part 21 to support the building 91; and a sensor unit 3 held in a base 31 attached to the lower part 21 of the jack main body 2 and is equipped with a downward vertical distance detection unit 32 that irradiates a laser beam to the ground surface 921, at a predetermined position B less susceptible to fluctuations of the ground surface 921 due to the jack main body 2, and measures a vertical distance from the predetermined position B to a laser beam emitting position. A sunk amount is detected by comparing vertical distances before jacking up or down and after jacking up or down.SELECTED DRAWING: Figure 1
【課題】自身のめり込み量を簡単、正確に検出するジャッキ装置を提供する。【解決手段】本発明のジャッキ装置１１は、建造物９１と地盤９２との間に配置され地盤の表面９２１に載置される被載置面２１１を持つ下方部２１と下方部２１に対して昇降し建造物９１を支える支持面２２１を持つ上方部２２からなるジャッキ本体２と、ジャッキ本体２の下方部２１に取り付けられる基部３１に保持されジャッキ本体２による地盤表面９２１の変動を受けにくい地盤表面９２１の所定位置Ｂに対してレーザー光を照射して所定位置Ｂからレーザー光発射位置までの垂直距離を測定する下方垂直距離検出部３２を備えるセンサー部３と、を有し、ジャッキアップ又はダウン前とジャッキアップ又はダウン後の垂直距離を比較することでめり込み量を検出することを特徴とする。【選択図】図１
