From the gap 74, the recess 26, the grooves 28, the sleeve joints 22, and the other passages 24. With the injection of the grout material, the air in each sleeve joint 22 is pushed out of the column main body 16 through the corresponding passage 24, and the air in the gap 74 passes through the groove 28, the sleeve joint 22 and the passage 24. The air in the recess 26 is pushed out of the column main body portion 16 and the air in the recess 26 is removed by the gap 74, the groove 28, and the sleeve joint 2.
2 and the passage 24 are pushed out of the column main body 16. Therefore, the grout material is used for each passage 24 and the recess 2
