PRESTRESSED MEMBER MANUFACTURING METHOD AND PRESTRESSED MEMBER
PROBLEM TO BE SOLVED: To provide a prestressed member manufacturing method and a prestressed member in which a sealing material is prevented from being damaged in manufacturing.SOLUTION: A prestressed member manufacturing method includes: a step of disposing a tensioner 3 to a tensioner insertion hole 20 formed in a beam body 2; a step of shielding a gap between an inner surface of the tensioner insertion hole 20 and the tensioner 3 with a sealing material 5; a step of inserting a tensioner 3 to a temporary anchor plate 7 and installing the temporary anchor plate 7 in the end face of the concrete member 2; a step of introducing a tensioning force into a tensioner 3; a step of introducing prestress into the beam body 2 through the temporary anchor plate 7 by releasing the tensioning force of the tensioner 3; and a step of filling a filler 4 in the tensioner insertion hole 20. An enlarged diameter part 21 having a depth not less than the length of the sealing material 5 is formed in the end of the tensioner insertion hole 20, and the sealing material 5 is installed in the center side of the beam body 2 from the enlarged diameter part 21.
【課題】製造時のシール材の損傷を防止することを可能としたプレストレスト部材の製造方法およびプレストレスト部材を提供する。【解決手段】梁本体２に形成された緊張材挿入孔２０に緊張材３を配設する工程と、緊張材挿入孔２０の内面と緊張材３との隙間をシール材５で遮蔽する工程と、緊張材３を仮定着板７に挿通するとともにコンクリート部材２の端面に仮定着板７を設置する工程と、緊張材３に緊張力を導入する工程と、緊張材３の緊張力を開放することで仮定着板７を介して梁本体２にプレストレスを導入する工程と、緊張材挿入孔２０内に充填材４を充填する工程とを備えるプレストレスト部材の製造方法であって、緊張材挿入孔２０の端部にシール材５の長さ以上の奥行きを有した拡径部２１を形成しておき、拡径部２１よりも梁本体２の中央側にシール５材を設置する。【選択図】図１
