HEAT RESISTANT FLOOR STRUCTURE FOR ROLLING STOCK

摘要

PROBLEM TO BE SOLVED: To provide heat resistant floor structure for rolling stock, that can obtain sufficient heat resistance even with strict restrictions on the whole thickness of floor structure. SOLUTION: A laminated body 3 comprising a metallic sheet 31 with a low fusing point and heat resistant insulating material 32 (33) is interposed between a floor structural member 1 and a floor panel 2 disposed on the floor surface. Heat from the outside is therefore dispersed to the whole area of the metallic sheet 31 using high heat conductivity of the metallic sheet 31 with the low fusing point, and heat transmission to the floor panel 2 is suppressed by heat absorption due to the fusion of the metallic sheet 31 with the low fusing point.
