摘要： An assembly-type car body (11) and a rail vehicle. A roof (1), an underframe (2), side roofs (3) and side walls (4) of the assembly-type car body (11) are separately formed by assembling double-layer pultruded profiles, and each double-layer pultruded profile comprises an outer plate, an inner plate and cavities formed by separating an interlayer between the outer plate and the inner plate using ribs; the upper edge and the lower edge of each side roof (3) are respectively connected to an edge of the roof (1) and the upper edge of a side wall (4) by means of lapping joints, and the lower edge of each side wall (4) is connected to an edge of the underframe (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 a plug joint, and the lower edge of the side wall connector (5) is connected to an edge of the underframe (2) by means of a push-to-connect joint (5-1).
