摘要： PROBLEM TO BE SOLVED: To solve a problem in a PC steel material wherein the breakage of the PC steel material due to rusting cannot be completely prevented.
SOLUTION: Sheaths 1 and 1 in which the PC steel material is inserted are connected to each other through a heat-shrinkable sheet 2. Next, the sheaths 1 are disposed so that the bent-up angle of the PC steel material in a PC beam becomes 20° or less. Also, the sheaths 1 are disposed so that the fixing of the PC steel material is performed on the vertical plane or lower surface of the PC beam. Namely, vertical tightening is ceased to prevent rain water from entering between a beam concrete and a post-filled concrete and prevent those portions less allowing grout to enter therein from occurring.
