MANUFACTURING METHOD OF PRESTRESSED CONCRETE MEMBER AND PRESTRESSED CONCRETE MEMBER
To improve workability of tendon.SOLUTION: A manufacturing method of prestressed concrete members includes a tendon tensioning process of spirally twisting and tensioning an outer tendon 20 and an inner tendon 30 in less than half a turn, and a concrete member forming process of introducing prestress on a concrete member 12 by casting concrete around the outer tendon 20 and the inner tendon 30 so that the outer tendon 20 and the inner tendon 30 are fixed to the formed concrete member 12.SELECTED DRAWING: Figure 1
【課題】本発明は、緊張材の施工性を向上することを目的とする。【解決手段】プレストレスコンクリート部材の製造方法は、外側緊張材２０及び内側緊張材３０を半回転未満で螺旋状に捩って緊張させる緊張材緊張工程と、外側緊張材２０及び内側緊張材３０の周囲にコンクリートを打設し、形成されたコンクリート部材１２に外側緊張材２０及び内側緊張材３０を定着させて当該コンクリート部材１２にプレストレスを導入するコンクリート部材形成工程と、を備える。【選択図】図１
