To provide a floor structure of a railway vehicle which inhibits corrosion caused by electric corrosion and achieves a certain level of fire resistance without increasing the vehicle weight.SOLUTION: A floor structure 1 of a railway vehicle includes: an underframe member 10 which is provided on a lower surface with an exterior device hanging groove 12 and made of aluminum; a heat shielding part 40A disposed below the underframe member 10 and formed by heat shielding plates 40 made of stainless steel; and a floor plate 44 disposed on the underframe member 10. The heat shielding part 40A is joined at a contact portion contacting with the underframe member 10 and a heat-resistant seal material fills gaps of the heat shielding part 40A. In the floor structure 1 of the railway vehicle, water does not enter gaps between the underframe member 10 and the heat shielding plates 40 and thus corrosion of the underframe member 10 caused by electric corrosion can be inhibited.SELECTED DRAWING: Figure 1
【課題】車両重量を増やすことなく、また、電蝕による腐食を抑制し、一定の耐火性能を有する鉄道車両の床構造を提供する。【解決手段】下面に外部機器の吊り溝12が設けられたアルミ製の台枠形材10と、前記台枠形材10の下方に配置される複数のステンレス製の遮熱板40からなる遮熱部40Aと、前記台枠形材10の上方に配置される床板44とを有し、前記遮熱部40Aは前記台枠形材10との接触箇所が接合され、前記遮熱部40Aの隙間には耐熱性シール材が充填されていることを特徴とする鉄道車両の床構造1は、台枠形材10と遮熱板40の間に水が入り込まないので、電蝕での台枠形材10の腐食を抑制することができる。【選択図】図1
