Abstract

一种侧墙上边梁，其特点是：侧墙上边梁本体为连续通长整体成型的不等边槽型的构件。本实用新型提高了强度、刚度，制造工艺简单，生产效率高，达到了国际通用技术标准的要求，提高了国产铁路客车的技术水平和等级。

Description

侧墙上边梁
技术领域：
本实用新型涉及铁路主型客车车体冷弯型钢，尤其是涉及一种侧墙上边梁。
背景技术：
按照国际铁路权威性动车组和客车车体强度、刚度设计标准要求，车体钢结构除了能够承受沿车钩缓冲装置纵向中心线作用的1500kN纵向压缩载荷外，还须在车顶与侧墙结合处能够承受300kN的纵向压缩载荷。而传统侧墙上边梁是分段压型后再拼接组焊成角形，因而不具备满足上述车体强度设计要求的能力，而且制造工艺复杂，生产效率低。
发明内容：
本实用新型所要解决的技术问题是提供一种结构强度、刚度水平高、制造工艺简单、生产效率高的侧墙上边梁，以克服背景技术存在的缺陷。
本实用新型的技术方案是：包括侧墙上边梁本体，侧墙上边梁本体为连续通长整体成型的不等边槽形构件。
本实用新型侧墙上边梁为整体成型且连续通长的不等边槽形的构件，因此，提高了强度、刚度，达到了国际通用技术标准的要求，提高了国产铁路客车的技术水平和等级。
附图说明：
附图是本实用新型的结构示意图。
具体实施方式：
参照附图，本实用新型包括侧墙上边梁本体1，侧墙上边梁本体1为连续通长整体成型且的不等边槽形构件。
