FIELD: transport.
SUBSTANCE: invention relates to railway transport. Body (1) of isothermic freight car includes side (3) and frontal walls, roof (5), floor (6) of multilayer structure with bottom, through centre sill, side, longitudinal, frontal, centre and lateral beams, top covering and insulation material in gaps between frame members, bottom and top covering. Side frame beams are made of angular profile the horizontal shoulder of which is connected with bottom and outside cladding of side wall, and vertical shoulder is fitted in insulation layer limited by interior and exterior claddings offside wall. Intermediate longitudinal beams are rigidly connected with floor top covering, rest on heat-insulating pads installed on lateral frame beams and are connected with intermediate longitudinal and lateral beams where heat-insulating gaskets are placed between connections.
EFFECT: invention improves body thermotechnical characteristics and reduces its metal consumption.
