RAILROAD BOXCAR SIDE WALL ASSEMBLY

摘要

A railroad boxcar has side wall assemblies that extend between the door fra me posts to the end walls of the car. The side wall assemblies has a set of vertical side posts mounted on pitched spacing to the outside of the wall sheet assemblies between the door frames and the end walls. The wall sheet assemblies include a numbe r of sheets lying in a common plane. The sheets abut along their edges. The adjoining sheets are welded at the seam between the adjoining edges. Rigid deformation s can be formed in the side wall sheets themselves between the vertical posts to provide local reinforcement to discourage local rippling and warping in the side wall sheets. The edges of adjacent sheets can be outwardly formed, and the weld made along an outwardly protruding ridge. Lateral stiffeners, in the nature of stringers, can be mounted between the tapered vertical stiffeners.
