いる。The reference display 6 may be formed by forming a reference groove 6 'as shown in FIG. 1 or may be formed with reference lines as shown in FIG. When the groove 6 ′ is formed and configured, the water thread 8 can be passed through the reference groove 6 ′ to be fitted, so that it is immediately understood whether the position of the anchor bolts 1 juxtaposed on the upper surface of the foundation is appropriate or not. The position of the anchor bolt 1 can be easily corrected (adjusted by hitting with a hammer). FIG. 2 shows a case where guide pieces 7 are provided vertically at every other three sides at the lower end of the hexagonal cylinder 3.
