部材の連結装置。 In the tunnel lining body, a pin member having a cap screw at the tip is buried in each of the opposing sides in the circumferential direction of the tunnel and the side in the axial direction of the tunnel, and The other lining has the tip protruding from the side surface of the lining, and the tip of the pin member is formed into a tapered part, and the pin member is adjacent to the lining. Insert it into the pin member insertion hole provided on each side of the body so as to face the bolt operation space formed on the back side of the pin member insertion hole,
Further, a bolt is screwed into the cap screw of the pin member from the bolt operation space on the other lining body side to tighten both lining bodies, and the pin in the circumferential direction of the lining body is tightened. A device for connecting precast members, characterized in that the member insertion hole is formed in a long hole shape in the direction of the shaft axis.
