METHOD FOR PRODUCING PRE-STRESSED CONCRETE
To provide means, when a non-metallic rope is applied as a tendon used for pre-stressed concrete, capable of more suitably introducing tensile force.SOLUTION: A method for producing pre-stressed concrete obtained by arranging a tendon 10 of a multi-row constitution at the inside of a flask A by stretching the tendon 10 made of a non-metallic rope while being folded at the outside of the flask, at least has: a step (A) of fixing an end part of the tendon 10 to a tensile force introduction tool 30; and a step (B) of providing a protective face for damage prevention on a surface of the tendon 10 regardless of before and after the introduction of tensile force to the tendon 10.SELECTED DRAWING: Figure 1
【課題】プレストレスコンクリートに用いる緊張材として非金属製ロープを適用した場合において、より好適に緊張力を導入可能な手段を提供すること。【解決手段】非金属製ロープからなる緊張材１０を型枠外で折り返しながら張設することで、型枠Ａ内に複数列構成の緊張材１０を配置してなるプレストレストコンクリートの製造方法であり、（Ａ）緊張材１０の端部を、緊張力導入具３０に定着する工程と、（Ｂ）緊張材１０に対する緊張力の導入の前後を問わずに、緊張材１０の表面に損傷防止用の保護面を設ける工程と、を少なくとも有する。【選択図】図１
