摘要： PROBLEM TO BE SOLVED: To secure expected quality and the safety of work while work efficiency is maintained when a plurality of bidirectional pretension members arranged in series are produced simultaneously.
SOLUTION: A plurality of the bidirectional pretension members 100 are produced by using a manufacturing bed in which a vertical cross-sectional shape in the transverse direction is set approximately in a U-shape. In each of a plurality of places in the longitudinal direction, a plurality of auxiliary PC steel materials 60 are arranged to penetrate a side wall 10B in the transverse direction in relation to one side wall 10B. Prestress is introduced in advance into each auxiliary PC steel material 60. The fixing of one end of each of a plurality of the transverse PC steel materials 104 to the side wall 10B is carried out by connecting one end of each transverse steel material 104 with the protrusion 60a from the inside surface of the side wall 10B of each auxiliary PC steel material 60. In this way, the length L2 of a part of each transverse PC steel material 104 which is shrunk by the release of tension is shortened to make the displacement D2 of a concrete member 106 small enough.
