TENSION FORCE INTRODUCTION METHOD FOR TENSION MEMBER
PROBLEM TO BE SOLVED: To provide a tension force introduction method for a tension member which can prevent entry of a degradation factor from an end part of the tension member.SOLUTION: A method of introducing a tension force of a tension member to a tension member of a prestressed concrete has: a tension member disposing step of disposing a first tension member 3 and a second tension member 4 constituting the tension member so as to face each other coaxially; a space-containing concrete member forming step for forming a space-containing concrete member 21 having space 51 for exposing mutually opposed end portions of the first tension member 3 and the second tension member 4, while the first tension member 3 and the second tension member 4 are inserted and fixed in such a manner that end portions thereof separated from each other are not exposed; a tension force introducing step for introducing a tension force in directions approaching each of the first tension member 3 and the second tension member 4 exposed in the space after the space-containing concrete member forming step; and a tension member connecting step for connecting the first tension member 3 and the second tension member 4 to which the tension is introduced, after the tension force introducing step.SELECTED DRAWING: Figure 4
【課題】緊張材の端部から劣化因子が侵入することを抑制できる緊張材の緊張力導入方法を提供する。【解決手段】プレストレスコンクリートの緊張材に緊張力を導入する緊張材の緊張力導入方法において、緊張材を構成する第１緊張材３と第２緊張材４とを対向させて同軸に配置する緊張材配置工程と、第１緊張材３および第２緊張材４の互いに離間する端部側が露出しないように挿入されて固定されるとともに、第１緊張材３および第２緊張材４の互いに対向する端部側をそれぞれ露出させる空部を有する空部有コンクリート部材２１を形成する空部有コンクリート部材形成工程と、空部有コンクリート部材形成工程の後に、空部５１に露出した第１緊張材３および第２緊張材４それぞれに互いに近接する方向の緊張力を導入する緊張力導入工程と、緊張力導入工程の後に、緊張力が導入された第１緊張材３と第２緊張材４とを接続する緊張材接続工程と、を有する。【選択図】図４
