WALL AND LOGISTICS TRACK CONSTRUCTION FOR A REFRIGERATED VEHICLE

摘要

An insulated and logistics track construction for the side and end walls of a refrigerated vehicle includes an exterior metal sheet attached to a plurality of vertical posts that are horizontally spaced. An interior sheet of fiber reinforced plastic (FRP) is spaced from the exterior sheet and attached to the vertical posts by a logistics track attached to each post with the FRP interior sheet captured between the logistics track and post. The logistics track is shorter than the posts, thereby leaving portions of the FRP interior sheet above and below the logistics tracks unattached and unrestrained by the posts. A mandrel with vertical tubes is positioned adjacent the FRP interior sheet while foam is introduced between the exterior sheet and interior sheet and the pressure of the foam forces the FRP interior sheet to create a flat inner surface between the vertically extending logistics tracks with the logistics tracks recessed below the flat inner surface and to create a corrugated shape in the surface of the FRP interior sheet above and below the logistics tracks.
