Abstract

The present invention discloses a sidewall structure of a hopper car, including: an integrally formed upper side beam (1), an integral sidewall panel (2), an integrally formed lower side beam (3) and a lower sidewall (4), wherein the upper side beam (1) is riveted with the integral sidewall panel (2) at the lower side; the sidewall panel (2) is riveted with the integrally formed lower side beam (3) at the lower side; the sidewall panel is of a panel-column structure in which the wall panel is integrated with a side column, and the side column is arranged at the inner side of the car body; the lower side beam (3) is riveted with the lower sidewall (4) at the lower side. According to the sidewall structure of the hopper car provided by the present invention, because of the sidewall panel with the integrally built-in side columns, the strength reduction resulting from rivet holes is avoided, the increased weight and cost resulting from rivets are avoided as well, and since the side columns are built-in, the spaces between the side columns are utilized to increase the volume of the car body.
