と言う欠点があった。In FIGS. 1 to 3, a plurality of male shag rugs 2 are attached and pushed to the outer surface of the reactor containment vessel 1 by bath welding, and a female shag 4 is attached to the base plate 3 in accordance with one rule outside of the mail shag 2. The base grate 3 is installed here and there, and several foundation bolts 5 are embedded and fixed in the A6 wall 6 next to the reactor. As shown in Fig. 4, the conventional base plate 3 and female shaft 4 are installed by cutting a double hole on both ends of the mail shaft 20, and opening a play hole in the female shaft 7 by inserting the hole 7 from the play hole +11U. Insert the screws to secure gaps a and b, and then tighten the screws (not shown) in the reactor-to-next connecting wall 6.
The reactor was fixed with shaped steel, etc., and the bolts 7 were removed.
Concrete was being poured for the next shielding wall 6. In the method described above, it is difficult to screw in the bolts 7 because the maymail shag 4 is installed inside the base plate 3, and even when removing the bolts 7, in addition to the above-mentioned reasons, the reinforcing bars are The drawback was that it was not easy to do because it was placed vertically and horizontally.
本発明の目的は、上記従来技術の欠点を無くしギャップ

Next, the fixing bolt 9 is inserted into the hole in the gap adjustment bolt 8, and is screwed into the threaded portion of the mail shag lug 2 to be fixed. As shown in FIGS. 6 and 7, the gap adjustment bolt 8 is made of a medium beam with a conical head, and the tip is conical so that it can easily fit into the hole in the mail shroud 2. The lower outer diameter part has a threaded shape. The fixing bolt 9 has a conical shape at the bottom of the head shown in FIG. 6, and the tip is notched in order to fix the base grate 3. As mentioned above, the weight of the base plate 3 assembled by the gear adjustment port 8 and fixing bolt 9 is transmitted and supported from the threaded portion to the conical portion and the threaded portion.
