The invention relates to the technical field of high-speed rails, and particularly discloses a high-speed rail roof structure. The high-speed rail roof structure comprises an end top assembly; the endtop assembly comprises end top top channel steel, a left end top bent beam, a right end top bent beam, an end top channel steel assembly and an end top plate. The left end top bent beam is welded onthe outer wall of one side of the end top top channel steel; the right end top bent beam is welded to the outer wall of the other side, away from the left end top bent beam, of the end top top steel channel, the end top steel channel assembly comprises a connecting block and an end top lower plate, and steel channel blocks distributed at equal intervals are welded to the outer wall of the bottom of the end top steel channel and the outer wall of the top of the end top lower plate. The high-speed rail roof structure has the beneficial effects that the top plate and the low fixed plate can achieve the heat insulation effect on high temperature generated by sunlight on the roof, the situation that the temperature in the vehicle rises too fast after the carriage roof is exposed to the sun canbe avoided, the use amount of cold air can be reduced, more cold air is saved, the end top stand columns can be fixed conveniently through the multiple steel channel blocks, and the bearing capacity of the roof can be improved through the multiple end top stand columns.

    本发明涉及高铁技术领域,具体是一种高铁车顶结构,包括端顶组件,端顶组件包括端顶顶部槽钢、左端顶弯梁、右端顶弯梁、端顶槽钢组件和端顶板,左端顶弯梁焊接在端顶顶部槽钢一侧的外壁上,且右端顶弯梁焊接在端顶顶部槽钢远离左端顶弯梁另一侧的外壁上,端顶槽钢组件包括连接块和端顶下板,端顶顶部槽钢底部的外壁上和端顶下板顶部的外壁上均焊接有呈等距离结构分布的槽钢块。本发明的有益效果:顶板和低昂定下板能够对阳光对车顶产生的高温具有隔热的作用,能够变免车厢顶暴晒后车内部的温度升高过快,能够减少冷气的使用量,更加节省,多个槽钢块方便对端顶立柱进行固定,多个端顶立柱能够增加车顶的承受力。
