There was a problem that would be.

本発明は、かかる状況に鑑みてなされたものであり、側構体の外板から車両幅方向外方に樋が突出することがなく、鉄道車両の外観を向上させることができる鉄道車両構体を提供することを目的とする。   The present invention has been made in view of such a situation, and provides a railway vehicle structure that can improve the appearance of the railway vehicle without protruding a ridge from the outer plate of the side structure outward in the vehicle width direction. The purpose is to do.

前記目的を達成するため、本発明に係る鉄道車両構体は、鉄道車両の側面を構成する一対の側構体と、鉄道車両の屋根を構成する屋根構体と、を備えるものであって、側構体は、略垂直に立ち上がるように形成された側外板と、側外板の車両内部側に配置されて車両長手方向に延在し側外板の上端より所定寸法下方に取り付けられた梁部材と、を有し、側外板及び梁部材により樋載置部が形成される。屋根構体は、屋根頂部から車両幅方向両端部になるに従って漸次下方に傾斜するように形成された屋根外板を有し、屋根外板の車両幅方向両端部が折曲されることにより略水平に延在する水平部と前記水平部から略垂直に立ち上がる垂直部とを有する樋が形成される。そして、側構体の樋載置部に屋根構体の樋が載置された状態で、側外板と樋の垂直部とがスポット溶接により締結されることにより、側構体と屋根構体とが結合されてなるものである。   In order to achieve the above object, a railway vehicle structure according to the present invention comprises a pair of side structures constituting the side surface of a railway vehicle, and a roof structure constituting a roof of the railway vehicle. A side outer plate formed so as to rise substantially vertically; a beam member disposed on the vehicle inner side of the side outer plate and extending in the vehicle longitudinal direction and attached below the upper end of the side outer plate by a predetermined dimension; The saddle placement portion is formed by the side outer plate and the beam member. The roof structure has a roof outer plate formed so as to be gradually inclined downward from the roof top to both ends in the vehicle width direction, and is substantially horizontal by bending both ends in the vehicle width direction of the roof outer plate. A ridge having a horizontal portion extending in a vertical direction and a vertical portion rising substantially vertically from the horizontal portion is formed. Then, the side structure and the roof structure are coupled by spot welding the side outer plate and the vertical part of the fence in a state where the roof structure is mounted on the side structure mounting section.

Since it is attached, the bending rigidity of the structure can be further increased.

また、本発明に係る鉄道車両構体において、梁部材のフランジ部の一方を側外板と樋の垂直部との間に挟持させ、側外板と梁部材のフランジ部と樋の垂直部とをスポット溶接により締結することもできる。   In the railway vehicle structure according to the present invention, one of the flange portions of the beam member is sandwiched between the side outer plate and the vertical portion of the eaves, and the side outer plate, the flange portion of the beam member, and the vertical portion of the eaves are combined. It can also be fastened by spot welding.
