PROBLEM TO BE SOLVED: To provide a method for manufacturing a railroad vehicle structure by which hanging bolt fixation for internal rigging is achieved by a simple structure.SOLUTION: A rigging structure forming step of fixing bolts 12 for rigging interior components 14 to a flat plate 13 includes: a bolt preparation step of preparing the bolts 12 including a head 21 of a substantially-rectangular shape, an engaged stage 22 formed at a bottom face side of the head 21 and a screw 23 protruded to the engaged stage 22; a flat plate preparation step of preparing the flat plate 13 having a long hole 32 with width allowing the head 21 to pass through the long hole 32; and a bolt engaging step of passing the head 21 of the bolt 12 through the long hole 32 from a rear side of a protrusion 31, rotating a direction of the head 21, pulling the bolt to a screw 23 side while hooking the head 21 to an edge 32a of the long hole 32, and deforming the protrusion 31 to an opposite side of the flat plate 13 to make the edge 32a of the long hole 32 engaged with the engaged stage 22 of the bolt 12.
【課題】簡単な構成で内艤装の吊ボルト固定を実現できる鉄道車両構体の製造方法を提供することを目的とする。【解決手段】平板13に内装品14を艤装するためのボルト12を固定する艤装構造形成工程において、艤装構造形成工程は、略直方体形状をなす頭部21と、頭部21の底面側に形成された係合段部22と、係合段部22に突設されたネジ部23とを有するボルト12を準備するボルト準備工程と、頭部21が通過可能な幅の長孔32が設けられた平板13を準備する平板準備工程と、凸部31の裏側からボルト12の頭部21を長孔32に通し、頭部21の向きを回転させ、頭部21を長孔32の縁32aに引っ掛けた状態でボルトをネジ部23側に引っ張ることによって凸部31を平板13の反対側に変形させ、長孔32の縁32aをボルト12の係合段部22に係合させるボルト係合工程とを備える。【選択図】図2
