The invention relates to the technical field of railway vehicles, and particularly discloses a layering structure of a special-shaped double-cavity pultrusion beam, which comprises a first cavity layering area, a second cavity layering area, an upper skin layering area and a lower skin layering area. Wherein the second cavity layer laying area is adjacently arranged on one side of the first cavity layer laying area; the upper skin layer laying area is laid above the first cavity layer laying area and the second cavity layer laying area, and the two sides of the upper skin layer laying area extend towards the outer sides of the first cavity layer laying area and the second cavity layer laying area respectively; the lower skin layer laying area is laid below the first cavity layer laying area and the second cavity layer laying area, and the two sides of the lower skin layer laying area extend towards the outer side of the first cavity layer laying area and the outer side of the second cavity layer laying area respectively. The layering structure provided by the invention is suitable for pultrusion process molding, so that pultrusion molding of the structural beam body becomes possible. The invention further discloses a railway vehicle and a laying implementation method of the special-shaped double-cavity pultrusion beam, and the technical effects are also achieved.

    本发明涉及轨道车辆技术领域,具体公开了一种异型双腔拉挤梁的铺层结构,包括第一腔体铺层区、第二腔体铺层区、上蒙皮铺层区和下蒙皮铺层区。其中,第二腔体铺层区相邻设于第一腔体铺层区的一侧;上蒙皮铺层区铺设于第一腔体铺层区和第二腔体铺层区的上方,且上蒙皮铺层区的两侧分别向第一腔体铺层区和第二腔体铺层区的外侧延伸;下蒙皮铺层区铺设于第一腔体铺层区和第二腔体铺层区的下方,且下蒙皮铺层区的两侧分别向第一腔体铺层区和第二腔体铺层区的外侧延伸。本发明提供的铺层结构,适用于拉挤工艺成型,使得该结构梁体采用拉挤成型成为可能。本发明还公开了一种轨道车辆和异型双腔拉挤梁的铺层实现方法,同样具有上述技术效果。
