ELONGATION LENGTH MEASUREMENT DEVICE
To provide an elongation length measurement device allowing detection of displacement of a tip position of a PC steel bar without removing a tension device.SOLUTION: An elongation length measurement device 1 is provided to a PC tension device 3, wherein the PC tension device 3 comprises: a fixation nut 21 attached on a projecting part 7a of the PC steel bar 7; a tension rod 11 to which a tip part 7b of the PC steel bar 7 is inserted and attached; and a hydraulic jack 13 for applying force to the tension rod 11, and applies tension force to the PC steel bar 7, and wherein the elongation length measurement device 1 measures an elongation length of the PC steel bar 7. The elongation length measurement device 1 comprises: a measurement rod that is slidably inserted to the tension rod 11, is biased so that its one end is abutted to a right end surface 7c of the PC steel bar 7, and includes a part exposed out of the tension rod 11; and a displacement acquisition part for acquiring displacement of the exposed part of the measurement rod.SELECTED DRAWING: Figure 2
【課題】ＰＣ鋼棒の先端位置の変位量を、緊張装置を取り外さずに検知可能にする伸長量計測装置を提供する。【解決手段】伸長量計測装置１は、ＰＣ鋼棒７の突出部分７ａに装着される定着用ナット２１と、ＰＣ鋼棒７の先端部７ｂが挿入され取付けられるテンションロッド１１と、テンションロッド１１に力を付与する油圧ジャッキ１３と、を有しＰＣ鋼棒７に緊張力を付与するＰＣ緊張装置３に設けられ、ＰＣ鋼棒７の伸長量を計測する。伸長量計測装置１は、テンションロッド１１に対してスライド可能に挿通されるとともに付勢力を受けて一端がＰＣ鋼棒７の右端面７ｃに突当てられており、テンションロッド１１の外に露出した露出部分を含む測定用ロッドと、測定用ロッドの露出部分の変位量を取得する変位量取得部と、を備える。【選択図】図２
