The riveting center sill structure comprises a traction beam and a middle truss girder, the traction beam comprises two layers of webs, the distance between the inner webs is 350 mm, and the distance between the outer webs is equal to the width of the middle truss girder; the middle truss girder comprises a triangular stable structure formed by inclined struts and vertical struts, a middle truss girder upper cover plate and a middle truss girder lower cover plate, the middle truss girder upper cover plate is in lap joint with the top of the traction beam, and the middle truss girder lower cover plate is in lap joint with the bottom of the traction beam; the middle truss beam upper cover plate and the top of the traction beam, the middle truss beam lower cover plate and the bottom of the traction beam, and the traction beam connecting stand columns and the middle truss beam connecting stand columns are fastened through riveting. The modular assembly mode is adopted, the requirements of vehicles with different lengths are met, installation is convenient, and transition between the traction beam and the fish-bellied sill is smooth.

    本发明涉及一种铆接中梁结构,包括牵引梁和中部桁架梁,牵引梁包括两层腹板,内腹板间距350mm,外腹板间距与中部桁架梁等宽;中部桁架梁包括斜撑、立撑形成三角形稳定结构,中部桁架梁上盖板和中部桁架梁下盖板,中部桁架梁上盖板搭接在牵引梁的顶部,中部桁架梁下盖板搭接在牵引梁的底部,并且,中部桁架梁上盖板与牵引梁的顶部、中部桁架梁下盖板与牵引梁的底部、牵引梁连接立柱与中部桁架梁连接立柱分别通过铆接紧固。本发明模块化组装模式,适应不同长度车辆要求,安装方便并且牵引梁和鱼腹梁之间过度顺畅。
