摘要： PROBLEM TO BE SOLVED: To provide a structurally simple segment gap adjusting device of a shield machine, which enables assembly of a segment to be easily and efficiently carried out by preventing mutual interference between the existing segment and the segment built into a last part of a segment ring. SOLUTION: A front end of a cylindrical casing is pivoted on one end of a segment end expanding/contracting cylinder 21 which expands/contracts in a radial direction of a tunnel, and a back end of the cylindrical casing is supported on a shield body 1 so as to be freely swingable over a prescribed distance in the radial direction of the tunnel via a trunnion coupling part. A segment end holding cylinder 23 inside the cylindrical casing 22 is extended to make free ends of the opposed segments S held from above and below by a holding member 24. Consequently, an end of an upper segment, which falls for contraction in an inside direction of the tunnel due to self-weight, can be expanded in the radial direction of the tunnel, and an end of the other upper segment, which falls in an outside direction of the tunnel due to self-weight, can be made smaller in diameter in the radial direction of the tunnel.

摘要： PROBLEM TO BE SOLVED: To provide a segment erector device which allows operations for conveying and assembling various types of segments to be smoothly and efficiently conducted without reference to the shape and height of a tunnel pit or the shape and number of division of the segment not only by bringing about simplification and downsizing of a structure but also by enabling miniaturization of the device. SOLUTION: An operating means (9) provided in a revolving superstructure (3a) is composed of a composite operating mechanism constituted by combining a link driving cylinder (12), a parallel link mechanism (13) which is coupled to the cylinder (12) and can move up and down, and an ascent/descent cylinder (11) which is coupled to the mechanism (13) and can move up and down independently of the mechanism (13). A central axis (1) of revolution of the revolving superstructure (3a) can be disposed in such a manner as to be deflected upward with respect to a central axis (1') of a tunnel, so as to enable securement of a lower space of the revolving superstructure (3a), which has the largest space required during the holding and assembly of the segment, and enable securement of a segment holding space, which is the smallest space required for the assembly of the segment, above the revolving superstructure (3a).

摘要： PROBLEM TO BE SOLVED: To obtain a joint fitting which can increase connection strength when a member to be connected is connected. SOLUTION: This joint metal for connecting the member to be connected comprises: a female joint 1 having an anchor part 6 continuously provided on the side of a joint part 5 having a fitting hole 4 formed in a jointing surface 3 facing a front side; and a male joint 2 having an anchor part 11 continuously provided on the side of a joint 10 in which a fitting protrusion 9 capable of being fitted into the fitting hole 4 formed in the joint part 5 of the female joint 1 is protrusively formed on a jointing surface 8 facing the front side. The joint fitting is formed in such a shape that the joining surfaces 3 and 8 of the joint parts 5 and 10 of the female and male joints 1 and 2 are parallel to axial centers of the anchor parts 6 and 11, and that the anchor parts 6 and 11 are bent in a cranked manner to the jointing surfaces 3 and 8 with respect to the joint parts 5 and 10, so that the jointing surfaces 3 and 8 of the joint parts 5 and 10 can correspond to the axial centers of the anchor parts 6 and 11. When the fitting protrusion 9 of the male joint 2 is fitted into the fitting hole 4 formed in the jointing surface 3 of the female joint 1 so that the jointing surfaces 3 and 8 of the female and male joints can be joined to each other, the axial center of the anchor part 6 of the female joint 1 corresponds to that of the anchor part 11 of the male joint 2.
