The invention relates to the technical field of railway vehicles, and provides a side top sectional material, a railway vehicle body and a railway vehicle. The side top sectional material comprises aside top body and an equipment mounting part, the side top body comprises an outer side skin and an inner side skin, and the inner side skin is provided with a first mounting groove; the equipment mounting part comprises a mounting transverse bar and a connecting longitudinal bar, a first end of the mounting transverse bar is connected to the outer side skin, a second end of the mounting transverse bar penetrates through the inner side skin and extends in the direction away from the outer side skin, a first end of the connecting longitudinal bar is connected to the second end of the mounting transverse bar, and a second end of the connecting longitudinal bar is connected to the first mounting groove. According to the side top sectional material, the installation stability of a side door mechanism and a side wall plate is improved, the structural strength and rigidity of the side top sectional material are improved, door area deformation is effectively prevented, and compared with the prior art, the influence of welding deformation and welding defects on the side top sectional material is reduced.
本发明涉及轨道车辆技术领域,提供一种侧顶型材、轨道车辆车体及轨道车辆。该侧顶型材包括侧顶本体和设备安装部,侧顶本体包括外侧蒙皮和内侧蒙皮,内侧蒙皮设有第一安装槽;设备安装部包括安装横筋和连接纵筋,安装横筋的第一端与外侧蒙皮连接,安装横筋的第二端穿过内侧蒙皮朝远离外侧蒙皮的方向延伸设置,连接纵筋的第一端与安装横筋的第二端连接,连接纵筋的第二端与第一安装槽连接。本发明提供的侧顶型材,不仅提高了侧门机构以及侧墙板的安装稳定性,而且提高了侧顶型材的结构强度和刚度,有效防止门区变形,与现有技术相比,减少了焊接变形和焊接缺陷对侧顶型材的影响。
