Summary:The utility model discloses a heat and sound insulation structure for a stainless steel underframe of an urban rail vehicle, which is provided with a corrugated floor (9) positioned on the lower side. A heat-insulation fiber blanket (2), an aluminum cellular floor (3) and floor cloth (1) are sequentially arranged on the corrugated floor (9). The heat and sound insulation structure is characterized in that a static damping sound insulation blanket (7) is arranged between the corrugated floor (9) and the heat insulation fiber blanket (2), and heat insulation fiber materials are filled in wave troughs of the corrugated floor (9). The heat and sound insulation structure is better in heat and sound insulation effects, leads passengers to feel comfortable, sufficiently uses a space of the corrugated floor, is convenient in laying and saves time and labor.
