The invention discloses a novel integrated car body side framework which is in left-right symmetry. The integrated body side framework is characterized in that two symmetrical surfaces form an integrated body by carrying out spot welding on the two symmetrical surfaces after integrated stamping, and an inner cavity is filled with a fireproof and heat-insulated foaming material. The integrated car body side framework comprises a post A, a front supporting beam, a doorsill beam and a post C which are connected into a whole; the post A is formed by splicing two stamped single-surface arc steel plates through spot welding, the cross section of the post A is of an asymmetric 8-shaped structure, the L-shaped upper end surface is connected with a roof through sheet metal adhesive, and the L-shaped lower end surface is used for clamping an adhesive tape and sealing a car door; the front supporting beam and the post A are formed into an integrated stamping piece. Compared with products in the same type, the weight is reduced by about 25%-30%, welding equipment and welding personnel are not excessively required, and batch welding production can be easily realized.
