PRESTRESS INTRODUCTION UNIT
To provide a prestress introduction unit capable of smoothly releasing a reaction force in a reaction force body.SOLUTION: A prestress introduction unit 1 according to the present invention comprises a PC steel bar 2, anchor plates 3a, 3b, cylindrical reaction force members 4a, 4b, and a reaction force release mechanism 5. The reaction force release mechanism 5 includes: wedge-shaped members 11a, 11b; sandwiching members 12, 13 sandwiching the wedge-shaped members from the sides; and two sets of bolts 14 and nuts 15 interconnecting the sandwiching members. By rotating each nut 15 in a loosening direction, the bolts 14, the nuts 15 and the sandwiching members 12, 13 relatively move the wedge-shaped members 11a, 11b so that the overall dimensions of the wedge-shaped members along a material axis 10 are shortened.SELECTED DRAWING: Figure 3
【課題】反力体における反力解放をスムーズに行うことが可能なプレストレス導入ユニットを提供する。【解決手段】本発明に係るプレストレス導入ユニット１は、ＰＣ鋼棒２と定着板３ａ，３ｂと筒状反力部材４ａ，４ｂと反力解放機構５とを備える。反力解放機構５は、楔状部材１１ａ，１１ｂと該楔状部材を側方から挟み込む挟み込み部材１２，１３と該挟み込み部材を相互に連結する２組のボルト１４及びナット１５とを備える。ボルト１４、ナット１５及び挟み込み部材１２，１３は、各ナット１５を緩み方向に回すことで、材軸１０に沿った楔状部材１１ａ，１１ｂの全体寸法が短くなるように該楔状部材を相対移動させるようになっている。【選択図】 図３
