A concrete base 51 is laid, and first and second concrete panel units 1 and 21 are placed thereon. Next, the first concrete panel unit 1 is joined from three directions adjacent to the second concrete panel unit 21 (see FIG. 5). At this time, the first, second, and third joint end faces 24, 24 of the second concrete panel unit 21
The first concrete panel unit 1 engages with the engaging portions 5a of the first joint end face 4a of the first concrete panel unit 1 with the respective engaging portions 25 of the first concrete panel unit 1 and the first concrete panel unit 21 with the walls 30a and 30b of the first concrete panel unit 21. The panel unit 1 is joined to the wall 10. When the first and second concrete panel units 1 and 21 are installed, the through holes 15 and 3
A bolt 53 is screwed onto a nut 52 fixed to the nut 5, and the bolt 53 is rotated to adjust the front, rear, left and right levels of the base 2 (see FIG. 6).

Then, until the wall of a predetermined length is obtained, the first
Adjacent to the concrete panel unit 1, a similar first
The concrete panel unit 1 is joined. That is, the engaging portions 5a, 5b of the first and second joint end surfaces 4a, 4b are wedge-engaged, and the wall portions 10 of the first concrete panel units 1, 1 are joined together. Hereinafter, the first concrete panel unit 1 and the second concrete panel unit 2
