PURPOSE:To exactly join unit walls by a method in which prior to the arrangement of supporting materials, a protective tool covering joint iron bars is inserted into the space on the joint iron bar side, a trench for the adjacent unit walls is excavated, and then the protective tool is removed out. CONSTITUTION:An iron bar cage 11 is fixed to one side of a partition steel plate 10, and an assembly 13 through which a joint iron bar 12 is thrust from the other side is set in a trench 9. The flange 6 of a protective tool 1 is inserted into the space on the joint iron bar 12 along a guide 16 to cover the iron bar 12, and a supporting material 17, e.g. gravel, etc., is packed into the space on the iron gar 12 side. Concrete is placed into the space on the iron bar cage 11 while preventing the leak of concrete by a sheet 14 to form an unit wall 18. Another trench 19 for the adjacent unit wall is excavated, soil and gravel 17 are taken out, and the protective tool 1 is removed. |
