After the grout pad has dried and solidified, the anchor bolt 85 is once removed, the leg plate 40 is removed, and the grout pad form 87 is removed. Grout pad 88
The state of adhesion to the floor B and the state of molding are checked, and if there is an abnormality (for example, if the air bubbles are above a predetermined value or if the adhesion to the floor B is weak), the ground pad 88 is broken and removed. Then, the grout pad mold 87 is placed again, and the non-shrinkable flowable grout material is injected to form the grout pad 88. When it is confirmed that there is no abnormality in the grout pad 88, the leg plate 40 is attached to the grout pad 8.
8 and a suitable liner shim 90 is inserted between the leg plate 40 and the grout pad 88 for fine adjustment of the height and the like of the leg plate 40, as shown in FIG. Fix with.

On the other hand, a method of fixing the leg plate 40 by the packer method will be described with reference to FIG. As shown in FIG. 8, first, floor B is chipped, and mortar 92 is provided thereon. Before the mortar 92 solidifies, the mortar 92
A packer iron plate 91 whose upper surface has been processed is placed on the upper part of the mortar, and the mortar 92 is dried and solidified in that state.
