The embodiment of the application relates to the technical field of railway vehicles, in particular to a connecting structure of a side wall stand column and an underframe boundary beam, a vehicle body and a railway vehicle. The connecting structure comprises a side wall stand column, a bottom frame edge beam and a connecting piece welded to the side, close to the arc-shaped face, of the bottom frame edge beam. The connecting piece is used for enhancing the connecting strength between the side wall stand column and the bottom frame edge beam. One part of the bottom end face of the side wall stand column is welded to the top face of the bottom frame edge beam, and the other part of the bottom end face of the side wall stand column is welded to the connecting piece. According to the connecting structure, the connecting piece is additionally arranged between the side wall stand column and the underframe boundary beam; the length of a weld joint between the underframe boundary beam and theside wall stand column can be increased through the connecting piece, so that connecting strength between the side wall stand column and the underframe boundary beam is improved, and a problem that the connecting strength of the existing vehicle body is reduced because the side wall stand column and the underframe boundary beam cannot be welded at the arc of the underframe boundary beam can be solved.
本申请实施例涉及轨道车辆技术领域,具体地,涉及一种侧墙立柱与底架边梁的连接结构、车体及轨道车辆。该连接结构包括侧墙立柱、底架边梁、焊接于所述底架边梁靠近所述弧形面一侧的连接件,所述连接件用于增强所述侧墙立柱和所述底架边梁之间的连接强度;所述侧墙立柱的一部分底端面焊接连接于所述底架边梁的顶面、且另一部分底端面焊接连接于所述连接件;该连接结构在侧墙立柱和底架边梁之间增设有连接件,通过连接件能够增加底架边梁与侧墙立柱之间的焊缝长度,进而提高侧墙立柱与底架边梁之间的连接强度,能够解决现有车体因侧墙立柱与底架边梁在底架边梁的圆弧处无法焊接而降低连接强度的问题。
