The embodiment of the invention provides a supporting structure of the two-layer floor of a double-layer train and a double-layer train. The supporting structure comprises a plurality of fixing seats,a plurality of supporting seats, and supporting beams; the fixing seats are fixed at intervals along the side wall cross beam of the double-layer train; the supporting seats are fixed to the side wall stand columns of the double-layer train respectively; each supporting seat is fixed to one corresponding side wall stand column; and the supporting beams are used for fixedly connecting the fixing seats and the supporting seats and fixing the two-layer floor. The double-layer train comprises the supporting structure of the double-layer floor of the double-layer train. With the supporting structure and the double-layer train adopted, the technical problem of low flatness of the side wall of the train body due to the large welding and fixing area of the supporting structure of the two-layer floor of the double-layer train and the side wall of a train body is solved.
本申请实施例中提供了一种双层列车二层地板的支撑结构和双层列车。支撑结构包括:多个固定座,各个所述固定座用于沿所述双层列车的侧墙横梁间隔的固定;多个支撑座,各个所述支撑座用于与所述双层列车的侧墙立柱固定,且一个所述支撑座用于与一个所述侧墙立柱固定;支撑梁,用于固定连接各个所述固定座和各个所述支撑座,且用于固定所述二层地板。双层列车包括上述双层列车二层地板的支撑结构。本申请实施例解决了双层列车二层地板的支撑结构和车体侧墙的焊接固定面积大导致的车体侧墙的平面度较低的技术问题。
