FIG. 1 is a cross-sectional view of a pretensioned precast concrete column 1 (hereinafter, simply referred to as a column) of the present invention.
A prestress is given in advance by the tendon 3 inserted in the axial direction. The pillar 1 is formed to have a length that can be transported by land transportation, and is used by being continuously connected at the site.

And six side wires 5. Further, the tension member 3 is not limited to the core wire 4 and the side wire 5 covered as described above, and may be a bare stranded wire or a single wire in which each wire is not covered, or may be a PC steel rod. .
【０００８】次にこの柱の製造方法について説明する。

スを付与することができる。Next, a method of manufacturing the pillar will be described.
First, as shown in FIG. 4, wiring is performed by penetrating the tension member 3 into a mold 6 arranged on a straight line at appropriate intervals.
After the tension member 3 is tensioned and fixed, the fixing tool 7 is installed on the tension member 3 near the formwork 6 with the wedge 7a. Even if the tension member is tensioned and the wedge 7a comes out of the fixing hole 7b,
By hitting the fixing device 7 from the inside, the fixing device 7 or the wedge 7a is brought into contact with the side surface of the mold 6 (FIGS. 5 and 6). Thereby, prestress can be applied to both ends of the column 1.

れる。After the tension member 3 is tensioned and fixed, concrete 8 is poured into a formwork 6 as shown in FIG. 7 and the tension member 3 is cut after it is hardened. The column 1 pre-stressed is manufactured.
【００１０】このプレストレスを付与する方法は、前記

【００１１】またこの柱１の製造方法として、３本の柱
１を一度に製造したが、これは勿論３本に限定されるも
