たり収まらず上記と同様の弊害がある。To solve this problem, the present applicant has previously filed Japanese Patent Application No. 1-165659 (Japanese Patent Application Laid-Open No. 3-33324).
As shown in FIG. 6, a spacer plate 4 'is disposed in a fool hole 3 of the base 2 into which the anchor bolt 1 is inserted, and the anchor bolt 1 is inserted into a hole eccentrically provided in the spacer plate 4'. Then, the seat plate 5 'is placed on the spacer plate 4', and the nut 6 is screwed onto the anchor bolt 1 on the seat plate 5 '. In this case, since the spacer plate 4 'is provided, the bending of the seat plate 5' can be prevented. However, since the separate spacer plate 4 'is used, there is a problem that the number of parts increases, and concrete adheres to the root of the anchor bolt 1. In this case, there is a problem that the spacer plate 4 'does not fit tightly and the nut 6 is not properly tightened. Japanese Patent Application Laid-Open No. Hei 2-13642 discloses an apparatus without increasing the number of parts. This is because the seat plate and the spacer plate are integrated, so that the number of parts does not increase. However, if concrete adheres to the root of the anchor bolt 1, the spacer plate does not fit exactly into the stupid hole, and has the same adverse effect as above. .

るにある。The present invention has been made in view of the above description, and the object of the present invention is not only to be able to absorb the variation in the position of the anchor bolt, but also to prevent the seat plate from being bent. It is an object of the present invention to provide a base mounting structure capable of stably tightening, reducing the number of parts, and preventing defects due to concrete adhesion to anchor bolts.

The anchor bolt 1 erected on the foundation 7 is attached to the base 2
The annular spacer portion 4 provided on the back surface of the seat plate 5 larger than the fool hole 3 is fitted into the fool hole 3 and the height of the spacer portion 4 is made shallower than the depth of the fool hole 3. A gap S is provided between the lower end of the spacer portion 4 and the upper surface of the base 7, and the anchor bolt 1 is inserted into the bolt through hole 8 provided eccentrically with respect to the annular spacer portion 4, and It is characterized in that the nut 6 is screwed into the anchor bolt 1 [Operation] The anchor bolt 1 is inserted through the fool hole 3 so that it is possible to absorb the variation in the position of the anchor bolt 1 and attach it. Since the spacer portion 4 is accommodated in the fool hole 3, bending of the seat plate 5 can be prevented. Since the spacer portion 4 is provided integrally with the seat plate 5, the number of components can be reduced. Further, since there is a gap S between the lower end of the spacer portion 4 and the upper end of the foundation 7, even if concrete adheres to the base portion of the anchor bolt 1, it can be avoided, and a tightening failure when the nut 6 is tightened can be eliminated. .

動かないように確実に固定できる。[Example] The foundation 7 is formed of concrete, and the anchor bolt 1 is protruded upward from the upper surface. As shown in FIG. 1, the base 2 is formed in an L shape by a horizontal piece 2a and a vertical piece 2b. An oblong hole 3 is drilled in the horizontal piece 2a of the base 2 so as to correspond to the position of the anchor bolt 1.
An anchor bolt 1 is inserted through an assembling hole 3 placed on the upper surface of the device. The seat plate 5 is formed in a disk shape as shown in FIG. 3, and an annular spacer portion 4 is integrally provided on the lower surface of the seat plate 5. The diameter of the seat plate 5 is larger than the minor axis of the oval hole 3. The spacer part 4 is the same as or slightly smaller than the minor axis. The seat plate 5 is provided with bolt through holes 8 eccentric to the annular spacer portion 4. The height of the spacer portion 4 is lower than the depth of the fool hole 3. The seat plate 5 is arranged on the horizontal piece 2 a of the base 2, the anchor bolt 1 is inserted into the bolt through hole 8, and the spacer plate 4 is fitted into the fool hole 3 by appropriately rotating the seat plate 5.
At this time, a gap S is formed between the lower end of the spacer portion 4 and the upper surface of the foundation 1, and even if there is a concrete attachment portion 10 at the base of the anchor bolt 1, it can be avoided. With the seat plate 5 placed thereon, the nut 6 is screwed into the anchor bolt 1 and tightened to hold down and fix the seat plate 5. At this time, since the spacer portion 4 is provided on the back of the seat plate 5, the seat plate 5 can be tightened with a constant force without bending. In the state where the base 2 is attached, even if a horizontal force as shown in P of FIG.
Since the spacer portion 4 is locked on the base 2, the base 2 can be reliably fixed so as not to move under the force.

The seat plate 5 is formed in a disk shape, an escape cavity 12 is provided below the vertical piece 2b of the base 2, and the escape cavity 12 is reinforced by a rib 13. This prevents the seat plate 5 from hitting the vertical piece 2b of the base 2 regardless of the direction in which the seat plate 5 is rotated due to the displacement of the anchor bolt 1.

る。[Effects of the Invention] In the present invention, as described above, the anchor bolt is inserted into the stupid hole of the base, and the nut is screwed and fixed to the anchor bolt via the seat plate. Of course, it can be attached and absorbed with holes, so the spacer under the seat plate is fitted into the fool hole, so when the nut is tightened, the seat plate is prevented from bending and with a fixed fastening force It can be securely attached, and the bolt holes are eccentric with respect to the spacer, so even if the position of the anchor bolt is misaligned, the seat plate can be rotated to fit the spacer into the stupid hole. The spacer part can be adjusted by adjusting the spacer part, and the spacer part is provided integrally with the seat plate, so that the number of parts can be reduced without increasing the number of extra parts. The spacer can be securely mounted so that the base does not move even if it is added, and the height of the spacer is made shallower than the depth of the fool hole, so that the lower end of the spacer and the upper surface of the base Since there is a gap between the anchor bolts, even if the base of the anchor bolt has a base concrete adhesion part, the spacer part does not hit and the spacer part can be securely inserted in the fool hole and the nut is securely tightened And can be securely fastened.
