The invention provides an upper-layer floor structure of a double-layer train. The upper-layer floor structure comprises an upper skin, a lower skin, a frame and a plurality of square tubes, wherein the frame is arranged between the upper skin and the lower skin and comprises an outer frame arranged in the circumferential direction and used for sealing the edges of the upper skin and the lower skin, a plurality of cross beams and a plurality of longitudinal beams, wherein the cross beams and the longitudinal beams are arranged in the outer frame in a crossed mode. The square tubes are vertically arranged in a cavity formed by the upper skin, the lower skin and the frame, so that the overall compression resistance is improved. Compared with the prior art, the invention has the following beneficial effects. According to the double-layer train upper-layer floor structure provided by the invention, firstly, a traditional metal material floor is replaced with a fiber composite material floor, so that the self-weight is reduced while the strength is increased; secondly, the overall pressure resistance is improved by arranging the square pipes inside; and finally, the effects of sound insulation and shock absorption are achieved by arranging the multiple square pipes into a honeycomb structure.
本发明提供了双层列车上层地板结构,包括由纤维复合材料制成的上蒙皮、下蒙皮、框架和方管;所述框架设置在所述上蒙皮和所述下蒙皮之间,所述框架包括设置在周向且对所述上蒙皮和所述下蒙皮封边的外框以及交叉设置在所述外框内的若干横梁和纵梁;若干所述方管竖直设置在所述上蒙皮、下蒙皮和所述框架形成的空腔内,以增大整体抗压性能。与现有技术相比,本发明的有益效果在于,本发明提供的双层列车上层地板结构首先通过将传统金属材质地板替换成纤维复合材料地板,在增大强度的同时降低自身重量,其次,通过在内部设置方形管提高整体抗压能力,最后,通过将若干方形管排布成蜂窝结构,达到隔音减震的效果。
