摘要： PROBLEM TO BE SOLVED: To easily assemble shield segments of which the dimensional precision of joints can be made course in some extent and as a result, the production cost of the segments can be reduced and further, a protrusion type joint can be pushed in a recess type joint with a weak force. SOLUTION: This shield segment is constituted of a segment body 4, a protrusion type joint 5 having a protruded side engagement face 5A, installed in the axial direction of a tunnel at one joint face of the circumferential direction of the tunnel in the segment body 4, and a recess type joint 6 having a recessed side engagement face 6A, installed in the axial direction of the tunnel at the other joint face of the circumferential direction of the tunnel in the segment body 4. The one protruded side engagement face 5A is mutually engaged with the other recessed side engagement face 6A of the segment body 4 to use them for a tunnel shielding method through which mutual segment bodies 4 can be connected. In this case, the engagement faces 5A, 6A are mutually connected by not the whole plane contact of the full length of a joint hardware of the engagement face but the partial contact thereof.

摘要： PROBLEM TO BE SOLVED: To absorb the position error of male and female fittings at the time of an assembly work, and prevent the appearance of a gap between both fittings by forming a projection streak on both sides of a buried fitting to clamp a dovetail web part, regarding a joint between dovetailed segments. SOLUTION: The breadthwise butt ends of segments have a buried fitting made of a male fitting 2A of T-shaped cross section and another buried fitting made of a female fitting 3 of C-shaped cross section respectively for mutual engagement and coupling. Projection streaks 2b and 2c are formed at both sides of the lower surface of a flange 2a as the tensile load acting surface of the male fitting 2A, and formed as the initial support point part where a tensile load acts. The deformation of the flange 2a is thereby facilitated until the occurrence of the prescribed displacement from a tensile displacement start point, upon the exposure of the flange 2a to an initial load as the tensile load, thereby reducing the apparent tensile rigidity of a joint 31. As a result, even if a proper positional relationship is not set between the male fitting 2A and the female fitting 3, tension is absorbed at the time of the coupling and engagement thereof, and the appearance of a gap between the male fitting 2A and the female fitting 3 is prevented.

摘要： PROBLEM TO BE SOLVED: To make a tunnel rigid in lining the interior wall of the tunnel using hexagonal segments by forming the segments so that joints between pieces of the segments are joined together into a spiral shape relative to the direction of the axis of the tunnel. SOLUTION: Segments 20 that are hexagonal, long plates are used, with three pairs of opposite sides 22a to 22f of each plate made parallel to one another. The sides 22a, 22d on the side between rings are held parallel and at equal distances to a diagonal 26 connecting a pair of corners 24b, 24e together, the adjacent two sides 22b, 22c are made to have different lengths via a pair of opposite corners 24b, 24e, and angles α, β are both set to range from not less than 90 to not more than 180 degrees. The plate is curved about the axis of the tunnel which is parallel to a line that orthogonally intersects the sides 22a, 22d on the side between the rings. The interior wall of the tunnel is lined with the segments 20, and joints on the side of the spaces between pieces of the segments 20 are formed into a spiral shape about the axis of the tunnel. Thus rigidity as a ring can be enhanced.

摘要： PROBLEM TO BE SOLVED: To increase the working bearing pressure, and to restrict the stress relaxation in comparison with a buffer material 5 made of the conventional rubber material while utilizing an advantage of a rubber material 9, and to secure the adhesive force between the rubber and a steel material in comparison with a case of using a layered rubber as a buffer material for a vibration isolation device. SOLUTION: A shaped body having a large modulus of elasticity such as a steel pipe 11 is integrally embedded in a rubber material 9. An intermediate modulus of elasticity between those of the rubber material and the steel pipe is obtained as a whole, and a working bearing pressure can be increased. Quantity of usage of the rubber can be reduced, and the stress relaxation can be restricted. A vibration control device having a function equal to the conventional layered rubber can be obtained by embedding plural concentrical ring-like steel pipes (not shown in a figure in usually) in the rubber material. In this case, since the steel pipe is embedded in the rubber material and has a large elastic force, peeling thereof from the rubber material is prevented, and adhesion is secured.

摘要： PROBLEM TO BE SOLVED: To perform connection between rings and pieces with ease and high strength by shifting a web frame shift to both flange frames, and forming a connection mechanism comprising complementary recess part and bump part on the connection surface. SOLUTION: A cylindrical multi-split arcuate steel shell 10 is formed by covering with skin plates 5 and 6 the outside of a web frame 9 having a beam web of a segment piece formed into a polygonal frame. Next, connection is effected by taking the webs in the direction of thickness of the steel shell 10 as connection surfaces between the rings and the pieces. In these shield segments, two pieces of substantially the same contoured flange frames 7, 8 are disposed along both the sides thereof in the circumferential direction of the web frame 9. Then, the web frame 9 is integrally connected in shifting relation with respect to both flanges 7, 8, and a connection mechanism consisting of complementary recess part and bump part is formed on the connection surface. By connecting the connection mechanism, connection is made with ease between the rings and the pieces.

摘要： PROBLEM TO BE SOLVED: To make it possible to easily connect lining members comprising a plurality of steel segments along the inner wall of a tunnel when supporting the inner walls of the tunnel. SOLUTION: H-section steel is used for girders 5 and 7 constituting steel segments as lining member 1. One of the tips of this U-shape formed by the H-section is butted thereby creating a state where the lining members are located adjacently. At the same time, other end of a fitting member 3 welded to one of the two U-shapes is fitted to the other U-shape. By this fitting, the coupling of the lining member 1 can be performed easily and strongly.

摘要： PROBLEM TO BE SOLVED: To provide a damper displaced by a compressive force and having the characteristics of an elasto-plastic body.
SOLUTION: In this shock absorbing damper, when a load is applied for compression, to the damping material filled in a clearance between a cylinder and a piston slidably inserted into the cylinder through the piston, the displacement of the damping material increases in proportion to the load. After the load reaches a specified load, the damping material flows through a clearance provided in the cylinder. While the damping material is flowing, the displacement increases by an amount equivalent to a reduction in the clearance to keep the load constant.
