COUPLER OF PC STEEL INTRODUCING PRESTRESS IN PRETENSION METHOD
To provide a pretension method causing no lowering of productivity and yield deterioration of an excessive length part, when introducing prestress into a concrete member.SOLUTION: A coupler 10 connecting PC steel materials with each other includes a first connection part 100 for connecting a first PC steel 30 being an excessive length part, a second connection part 200 for connecting a second PC steel 20 being a manufacturing section, and an adjusting part 300 with one end along the axial direction of the PC steel connected to the first connection part 100, the other end along the axial direction of the PC steel connected to the second connection part 200, for adjusting the length along the axial direction from the first connection part 100 to the second connection part 200. The adjusting part 300 includes a hollow PC steel bar 340 and a solid PC steel bar 330 changing the axial length by changing the insertion length into the hollow PC steel bar 340.SELECTED DRAWING: Figure 2
【課題】プレテンション方式においてコンクリート部材にプレストレスを導入する場合に、生産性を低下させず余長部の歩留りを悪化させない。【解決手段】ＰＣ鋼材どうしを接続する接続具１０は、余長部である第１のＰＣ鋼材３０が接続される第１の接続部１００と、製造部である第２のＰＣ鋼材２０が接続される第２の接続部２００と、ＰＣ鋼材の軸方向に沿った一端が第１の接続部１００に接続され、ＰＣ鋼材の軸方向に沿った他端が第２の接続部２００に接続され、第１の接続部１００から第２の接続部２００までの軸方向に沿った長さを調整する調整部３００とを含む。調整部３００は、中空ＰＣ鋼棒３４０とこの中空ＰＣ鋼棒３４０に挿入される長さを変更することにより軸方向の長さが変更される中実ＰＣ鋼棒３３０とを含む。【選択図】図２
