PROBLEM TO BE SOLVED: To connect wall panels of different height to each other without requiring any spacer. SOLUTION: A pulling block 180 of which mounting height can be varied is installed on a high wall panel, and a pulling surface 192 overlapped with upward wedge surface 80 of a wedge block mounted onto a low wall panel or other posts is formed on the lower surface of the pulling block 180. Also a pulling bar shaft 96 of which lower end is screwed is inserted into the pulling block 180 and tightened so as to closely attract the wedge surfaces 192 and 80 to each other and connect the adjacent wall panels of different height at a height difference. |
