The invention relates to the technical field of railway vehicles, in particular to a double-skin splicing structure and a double-skin splicing vehicle body. The double-skin splicing structure comprises a first double-skin unit and a second double-skin unit, the first double-skin unit and the second double-skin unit are spliced, a closed groove is formed in the splicing position, a reinforcing piece is arranged in the closed groove, the sides, close to a carriage, of the first skin unit and the second skin unit are riveted with the reinforcers through rivets. Carbon fiber flitch plates are adhered to a first notch and a second notch, so that the strength of the splicing position is enhanced, the flame resistance of the vehicle body is enhanced, and the safety performance of the vehicle body is greatly improved; the double skins adopt composite materials and hollow structures, so that the overall weight of the vehicle body is reduced, the sound insulation and heat insulation performance of the vehicle body is improved, and the impact resistance and the impact resilience deformation resistance are enhanced; and through the design of the double-skin splicing structure, the double-skin forming process is simple, the double-skin production efficiency is improved, and the cost is reduced.
本发明涉及轨道车辆技术领域,尤其涉及一种双蒙皮的拼接结构及双蒙皮拼接车身,包括:第一双蒙皮单元和第二双蒙皮单元,第一双蒙皮单元和第二双蒙皮单元拼接,且在拼接处形成封闭槽,在封闭槽内设有加强件,第一蒙皮单元和第二蒙皮单元靠近车厢一侧通过铆钉与加强件铆接。通过第一凹口和第二凹口处胶粘碳纤维贴板,增强了拼接处的强度,增强了车身的抗阻燃性能,大大提高了车体的安全性能;双蒙皮采用复合材料及空心结构,降低车身的整体重量,提高了车身的隔音、隔热性能,增强了抗冲击性和抗冲击回弹变形能力;本发明通过双蒙皮拼接结构设计,使双蒙皮成型工艺简单,提高了双蒙皮生产效率,降低成本。
