PROBLEM TO BE SOLVED: To provide a PC frame body reducing the constitution members and securing a quality of the joints. SOLUTION: A PC unit 18 includes two member-connection parts 20, 22 arranged in substantially T-shaped upper and lower parts formed at the upper and lower ends of a vertical material 16. Upper and lower horizontal material pieces 12a, 14a made by dividing the upper and lower horizontal materials are integrally formed in both ends of the vertical material 16, to form a substantially I-shape When forming a frame body 10, the PC unit 18 is arranged so that the piece side 12a is positioned at the upper part and other PC units 18 are installed adjacent thereto. Other PC units 18 are arranged upside down so as to position the piece side 12a in the lower side. As the mutual ends of the upper and lower horizontal material pieces 12a, 14a face each other in a pair of PC units 18, the mutual ends are moved in the thrust direction to connect theses through a joint 24 and by repeating the same operation a rigid shaped PC frame body 10 with a required length can be constructed.
