The embodiment of the invention provides a floor device and a railway vehicle. The floor device comprises: a bottom plate assembly which is used for providing support for a vehicle body; a heat insulation layer which is used for insulating heat above and below the vehicle body; a built-in floor which is used for providing support for personnel and equipment in the vehicle; the bottom plate assembly, the heat insulation layer and the built-in floor are sequentially arranged from bottom to top; a ground beam which is fixedly connected with the bottom plate assembly, wherein the ground beam is arranged below the built-in floor for supporting; an auxiliary supporting assembly which is fixed to the two sides of the bottom plate assembly in the width direction and is used for being fixedly connected with side walls of the vehicle body so as to provide deformation-resistant rigidity for the bottom plate assembly. According to the floor device and the railway vehicle, the auxiliary supporting assembly is arranged on the two sides of the bottom plate assembly in the width direction and are fixedly connected with the side walls of the vehicle body, so that the rigidity of the bottom plate assembly is increased, a bending deformation of the bottom plate assembly at high temperature can be restrained, and the bearing performance of the floor device at high temperature is effectively improved; time is won for evacuation or escape of passengers.

    本申请实施例中提供了一种地板装置及轨道车辆,包括:底板组件,用于为车体提供支撑;隔热层,用于隔绝车体上方和车体下方的热量;内装地板,用于为车内人员及设备提供支撑,底板组件、隔热层、内装地板自下至上依次设置;地梁,与底板组件固定连接,地梁设于内装地板的下方进行支撑;固定于底板组件宽度方向的两侧的辅助支撑组件,用于与车体侧墙固定连接,以为底板组件提供抗变形刚度。应用地板装置及轨道车辆,在底板组件的宽度方向的两侧设置辅助支撑组件,辅助支撑组件与车体侧墙固定连接,增加底板组件的刚度以对底板组件在高温下的弯曲变形进行抑制,有效提高地板装置在高温下承重性能;为乘客疏散或逃生争取时间。
