摘要： PROBLEM TO BE SOLVED: To easily fit a joining fitting provided on the joining end face of a segment to a form. SOLUTION: A locking mechanism 22 for locking a joining fitting 3 to be fitted to an end plate 21 is provided on the end plate 21 of a form for forming the joining end face of a segment. The locking mechanism 22 is formed by a rod 24 passed through a hole 23 formed in the end plate 21 to be rotatably supported, a plate-like locking member 25 which is provided on the tip of the rod 24 and thinner than the gap between the locking piece parts 5 of the joining fitting 3, and a gripping part 26 provided on the rear end part of the rod 24 on the back side of the end plate 21. With the locking member 25 made horizontal, the joining fitting 3 is pressed to the end plate 21 with the locking member 25 passed between the locking piece parts 5. The gripping part 26 is held to turn the rod 24 in about 90-degree arc, the locking member 25 is turned, the locking part 25a of the locking member 25 is disposed on the locking surface 9 side of the locking piece part 5 of the joining fitting 3 and locked, and the joining fitting 3 is fitted to the end plate 21 by the locking force.

摘要： PROBLEM TO BE SOLVED: To easily fit a joining fitting provided on the joining end surface of a segment to a form. SOLUTION: A hole 22 is formed in an end plate 21 of a form for forming a joining end surface of a segment. A fitting screw hole 24 is formed in a locking piece part 5 of a joining fitting 3 provided on the joining end surface of the segment. With the joining fitting 3 disposed in a fixed position of the end plate 21, a fitting screw 23 is inserted from the hole 22 formed in the end plate 21, and screw-engaged with the fitting screw hole 24 of the joining fitting 3, whereby the joining fitting 3 is fitted to the end plate 21 by fastening force. A foaming material 25 is put in the engagement space 8 of the joining fitting 3.

摘要： PROBLEM TO BE SOLVED: To join segments mutually, easily and surely in the tunnel peripheral direction. SOLUTION: C-shaped sectional joint metals 2 with a pair of locking sections 5 formed in a hooked shape are installed at the joint end faces 1a of the segments 1. Engaging sections 6 formed at both end sections of a connecting fitting 3 are inserted into engaging spaces 7 between the locking sections 5 of each joint metal 2 under the state, in which the joint end faces 1a of the segments 1 are abutted mutually, and the joint metals 2 are clamped mutually. The joint metals 2 are arranged at places slightly pulled in from the joint end faces 1a of the segments 1.
