摘要： PROBLEM TO BE SOLVED: To assure the safety of human lives and facilities without collapsing a shield tunnel even if the displacement of a fault occurs due to an probable earthquake in the future in the shield tunnel passing the fault with a fault fracture zone. SOLUTION: In a segment ring structure forming the primary lining part of the shield tunnel, the ring structure is constructed by connecting segments 14. In segment rings 12 adjacent to each other, the segments 14 are arranged staggered by shifting inter-segment joints 5 to each other so as to form a primary lining part body in which the ring structures adjacent to each other reinforce each other. The inter-ring joints of the segment rings 12 are formed of inter-ring joints 16 with a high rigidity and a high strength and inter-ring joints 15 with a rigidity lower than that of the inter-ring joints alternately combined with each other in the longitudinal direction of the tunnel with all the periphery of the tunnel taken as a unit.

摘要： PROBLEM TO BE SOLVED: To provide a fire-resistive covering structure in a tunnel, easy in installing and removing a fire-resistive covering member to a tunnel primary lining body, capable of absorbing the expansion of a metallic panel in a fire, and superior in an appearance.
SOLUTION: In this fire-resistive covering structure in the tunnel, the fire-resistive covering structure is used inside the primary lining body of the tunnel; and is composed of a joint plate provided with at least two joining pins, the fire-resistive covering member joined with a panel part heat insulating material, by exposing a peripheral joint part of the metallic panel, to the back face side of the metallic panel, and a peripheral directional and shaft directional support metal fitting. A large number of joint plates are fixed at a prescribed interval to the primary lining body of the tunnel by an anchor bolt. The fire-resistive covering member constitutes the joint part, by making contact the mutual adjacent panel part heat insulating materials, and is fixed to the joint plates via the joining pins, by the peripheral directional and shaft directional support metal fitting overlapping on an end part of the metallic panel, by covering the joint part.

摘要： PURPOSE:To raise the efficiency of fireproof covering work for steel framed structures by a method in which a covering-forming thin steel plate formed by bonding a thin steel plate with a heat-expandible fireproof film by adhesive is doubled with a steel framed structure and moulded into various forms. CONSTITUTION:A covering-forming thin steel plate 2a Consisting of a thin steel plate 4 and a heat-expandible fireproof film 5 is bonded through adhesive 6 to the surface of H-steel 1 as a column material. The plate 2a having various shapes such as oblong or grooved forms to match the surface of forms of steel framed structures to be covered is produced in factory in advance. The plates 2a, 2b, 3a, and 3b are attached to the outside of the web and flange of H-steel 1 as a column material on construction site. The fireproof covering work for steel framed structures can thus be efficiently attained at low cost on construction site.
