Vehicle body of assembly type and railway vehicle

Abstract

A self-assembly body (11) and a railway vehicle. A roof (1), a lower frame (2), side roofs (3), and side walls (4) of the self-assembly body (11) are formed separately by assembling double-layer pultruded profiles, each double-layer pultruded profile comprising an outer plate, an inner plate, and cavities formed by separating an intermediate layer between the outer plate and the inner plate by means of ribs; the upper edge and lower edge of each side roof (3) are respectively connected to an edge of the roof (1) and to the upper edge of a side wall (4) by means of overlapping joints, and the lower edge of each side wall (4) is connected to an edge of the lower frame (2) by means of a side wall connector (5);Each side wall connector (5) is a double-layer pultruded profile unit; the upper edge of the side wall connector (5) is connected to the lower edge of the side wall (4) by means of a plug joint, and the lower edge of the side wall connector (5) is connected to an edge of the lower frame (2) by means of a snap-on connection joint (5-1).
