ツト部材６が埋込まれている。Next, a pair of arc-shaped PC pillars 2 are assembled into an arch shape at the site, and the two sets of arc-shaped PC pillars 2 are assembled diagonally across each other as shown in FIGS. 1 and 3. Then, by inserting the PC steel material 7 into the duct 4 with the four arc-shaped PC pillars 2 arranged diagonally, the arc-shaped PC columns 2 forming a pair are formed.
Connect the upper end part of C column 2, and concrete 8 at the top.
After compacting and solidifying, the PC steel materials 7 are tensioned and joined together to form a concrete framework 10 consisting of two arch-shaped PC columns 9. In this case, the concrete framework 10
The lower end 11 of each arc-shaped PC column 2 is made of foundation concrete 12
embedded and fixed. This concrete framework 10
A plurality of PC columns are arranged in parallel in the longitudinal direction of a road, etc., and arch-shaped PC pillars 9A serving as entrances and exits are installed at the front and rear. This arch-shaped PC column 9A is provided with a plurality of through holes 5 and a nut member 6. Further, the arch-shaped PC columns 9A at the front and rear ends and the top of the concrete frame 10 are connected by a beam material 13, and wires 14 are inserted into each of the through holes 5, and both ends of the wires are fixed to the front and rear arch-shaped PC columns 9A. It is fixed via member 15. Further, nut members 6 are embedded in both sides of the upper surface of the foundation concrete 12.
