MANUFACTURING METHOD, AND PRECAST AND PRESTRESSED CONCRETE BEAM MEMBER

摘要

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
