PRESSURE MEASUREMENT DEVICE

To provide a judgment index (confirmation means) for pressure (adhesion) by interposing it between a pressing member such as a bag and a pressed member such as a steel shoring.SOLUTION: The present invention is a pressure measurement device interposed between a pressing member P and a pressed member D. The pressure measurement device is a pressure sensing sheet member 1. The pressure sensing sheet member 1 is integrally sealed such that a top sheet S and a back sheet B have a housing space 2 therein. The housing space 2 is formed by a pressed space 21, a liquid inflow space 22, and a partition 23 that partitions both spaces 21 and 22. The pressed space 21 is filled with a colored liquid C. When a pressure equal to or higher than a set value is applied from the pressing member P to the pressed space 21, the partition 23 breaks and the colored liquid C in the pressed space 21 flows into the liquid inflow space 22. The pressure measurement device may include a pressure detection sheet member and a pressure adjustment member 9.SELECTED DRAWING: Figure 1 【課題】袋体等の押圧部材と鋼製支保工等の被押圧部材との間に介在させることにより、圧力（密着性）の判断指標（確認手段）を提供する。【解決手段】押圧部材Ｐと被押圧部材Ｄとの間に介在される圧力測定装置であって、前記圧力測定装置は、圧力検知シート部材１であり、前記圧力検知シート部材１は、表面シートＳと裏面シートＢとが内部に収容空間２を有するように一体にシールされ、前記収容空間２は、被押圧空間部２１と液体流入空間部２２と両空間部２１、２２を仕切る仕切り部２３とで形成され、前記被押圧空間部２１には着色液Ｃが充填され、前記押圧部材Ｐから前記被押圧空間部２１に設定値以上の圧力が作用すると前記仕切り部２３が破断して前記被押圧空間部２１内の前記着色液Ｃが前記液体流入空間部２２へ流れ込む構成とされている。前記圧力測定装置は、圧力検知シート部材と圧力調整部材９とで構成される場合もある。【選択図】図１
