MANUFACTURING METHOD, AND PRECAST AND PRESTRESSED CONCRETE BEAM MEMBER
PROBLEM TO BE SOLVED: To enable cost reduction when warping of a PCaPC beam member is reduced.SOLUTION: A method of manufacturing a precast and prestressed concrete beam member comprising a tendon extended in a beam axis direction on a lower end side with respect to the center of a cross-section of the member includes the steps of: arranging an adjustment member extended in the beam axis direction on an upper end side with respect to the center of the cross-section of the member; and introducing a tensile force into the adjustment member independently of the tendon so as to reduce warping caused in the beam member by a tensioning force introduced into member concrete of the beam member by the tendon.SELECTED DRAWING: Figure 3
【課題】ＰＣａＰＣ梁部材の反りを低減するにあたり、低コスト化を可能とすること。【解決手段】部材断面中央よりも下端側において梁軸方向に延びる緊張材を備えたプレキャストプレストレストコンクリート梁部材の製造方法であって、部材断面中央よりも上端側において梁軸方向に延びる調整材を配置する工程と、前記緊張材により前記梁部材の部材コンクリートに導入される緊張力によって前記梁部材に生じる反りを低減するように、前記緊張材とは独立して前記調整材に張力を導入する工程と、を含む。【選択図】図３
