REFRACTORY PANEL FOR TUNNEL AND FIRE RESISTIVE COVERING STRUCTURE IN TUNNEL

摘要

PROBLEM TO BE SOLVED: To provide a refractory panel which exposes a heat insulating material from an interval between the refractory panel per se and an adjacent metallic plate due to thermal expansion even if an in-tunnel fire breaks out, prevents high-temperature gas generated by the fire from directly touching at the refractory heat insulating material, and prevents the high-temperature fire and the high-temperature gas from intruding into a porous body of the heat insulating material.;SOLUTION: The refractory panel 1 for the tunnel, is for use on an inner side of a primary lining body 4 mounted in a shield tunnel or the like, and formed of steel reinforced concrete, iron, or a complex body consisting of steel reinforced concrete and iron. The refractory panel 1 is formed of the heat insulating material 3 including a metallic plate 2 covering a surface on the side of a tunnel internal space. According to the refractory panel 1, the periphery of the metallic plate 2 of the refractory panel is overlapped on the periphery of the metallic plate 2 of another refractory panel adjacent to the refractory panel concerned.;COPYRIGHT: (C)2002,JPO
