PROBLEM TO BE SOLVED: To provide a method for manufacturing a PC wall material using a simple apparatus at a low cost, which can manufacture a PC wall material using a conventional stressed abut and introduce the predetermined prestress to the end part thereof. SOLUTION: A PC steel material is constructed between stressed abuts 27 with a PC steel material 13 having a screw 23 for fixing by a nut, and a screwed PC steel material 13 is allowed to penetrat a PC steel material inserting hole 21 in fixing plates 15 positioned at a predetermined interval, the plates being workable as a form and a fixing plate, whereby the material is fixed on the stressed abut 27. Then, the screwed PC steel material 13 is stressed, concrete 14 is introduced between the both fixing plates 15, and a fixing nut 24 set forth in the PC steel material is tightly fixed to the fixing plates 15 before stress of the screwed PC steel material 13 is released. Finally, stress of the PC steel material 13 is released after curing concrete. COPYRIGHT: (C)2005,JPO&NCIPI
