Next, the oval bolt 7 is inserted into the bolt hole 2 of the receiving frame 1, and its tip is inserted into the anchor bolt 12, which has the same inner diameter as the long outer diameter of the bolt 7, which has been buried in the concrete pipe 8 in advance. The anti-rotation washer 5 is mounted on the receiving frame 1 adjacent to the locking protrusion 3 of the receiving frame 1 by screwing and fixing and inserting the oval bolt 7 into the oval bolt hole 6. , furthermore, a bolt 7 is attached to the head of the oval bolt 7.
The anti-rotation washer 5 and the receiving frame 1 are tightened to the concrete pipe 8 by screwing together a nut 10 having the same inner diameter as the long outer diameter of the concrete pipe 8, thereby assembling the entire structure.

。In the figure, 11 is a concrete pipe 8 around the adjustment washer 9.
This is mortar filled in the gap between the frame 1 and the frame 1. Kusaku
As mentioned above, in the method according to the present invention, since the oval bolt is inserted into the oval bolt hole of the anti-rotation washer,
Its rotation is prevented by the washer, and the washer stands up on the upper surface of the receiving frame! Since the bolt and nut are adjacent to the protrusion and are prevented from rotating by this protrusion, the bolt and nut will not rotate even when the vibration of a car etc. occurs. By fixing the bolt to the bolt using a known method, it is possible to easily prevent the bolt from rotating, and this completely prevents the bolt and nut from loosening, which previously would have been caused by the rotation of the bolt. It is possible to completely prevent the receiving frame and the manhole cover fitted to the receiving frame from loosening and coming off.
