13をケース20内へ押し嵌入する。Next, the connection operation will be described. A connection pin 13 is screwed to the nut 8 at a connection site. One connecting member 1 faces the other connecting member 2 so that the connecting pin 13 faces the case 20. Then, one connecting member 1 is moved to the other connecting member 2, and the connecting pin 13 is pushed into the case 20.

する。At the time of insertion, the connecting pin 13 is guided into the insertion hole 20a by the engagement between the tapered portion 16b and the guide surface 22. At this time, when the connecting pin 13 and the case 20 are slightly eccentric, the adjusting member 9 made of an elastic material is present on the outer peripheral portion of the nut 8 and the outer peripheral portion of the anchor bar 5 is provided by the gap holding pipe 10. Void 1
2, the connecting pin 13 moves in the diameter direction, that is, toward the axis of the case 20, and the connecting pin 13 and the axis of the case 20 match even in the eccentric state as described above, The connecting pin 13 is securely fitted into the case 20.

相互に係止する。この係合状態において、両連結部材
1、2が相互に最接近した接合状態となる。When one connecting member 1 is further moved, the connecting pin 13 is reduced in diameter by the split groove 19 and slides into the insertion hole 20a to enter. When the connecting pin 13 is further advanced, the taper plug 25 is fitted into the hole 18, the connecting pin 13 is expanded in diameter, the locking flange 16a is fitted into the locking groove 23, and the locking surface 16c is formed. Face the locking surface 23a of the locking groove 23 and lock each other. In this engaged state, the two connecting members 1 and 2 are in the joined state in which they are closest to each other.

ピン13が縮径して抜け外れることが確実に防止され、
両連結部材1、2の相互の連結が確実に保持される。By locking as described above, the connecting pin 13 is prevented from coming off and the connecting members 1 and 2 are connected to each other. Also, if the connecting pin 13 moves in the disengagement direction, the frictional resistance between the connecting pin 13 and the main body 25a of the tapered plug 25 increases the friction between the temporary fixing portion 25c of the tapered plug 25 and the connecting plate 24. By being larger than the resistance, the temporary fixing portion 25c slides with respect to the connecting plate 24, and the tapered plug 25 moves with the connecting pin 13,
Diameter deformation of the connecting pin 13 is prevented. Therefore, it is reliably prevented that the connecting pin 13 is reduced in diameter and comes off.
The mutual connection between the two connecting members 1 and 2 is securely held.

容易になる。In this buried state, a gap is formed between the gap holding pipe and the anchor bar, and the presence of the adjusting member made of an elastic material and the seat member made of the elastic material allows the tip of the anchor bar to move. It can move in its diameter direction. Therefore, even if the connecting pin is slightly eccentric from the predetermined position before the connection, the connection can be performed, and the connecting operation is facilitated.
