The wall construction includes a sheet-like panel reinforced with vertical stiffeners. The panel and the stiffeners are made of nonmetallic material and the stiffeners are adhesively bonded to the panel. The stiffeners each include an outwardly facing surface having a generally parabolic shape. ## Claims ### Claim 1 A vehicle body comprising top, bottom, and opposite side walls interconnected to form a box-like structure, said side walls including a plurality of skin members, each of said plurality of skin members having edges, said skin members being arranged in edge to edge relation and being respectively adhesively bonded to one another to form a sheet-like side wall panel; and a plurality of stiffeners for reinforcing said sheet-like side wall panel, each of said plurality of stiffeners having a rib member including a side portion being adhesively bonded to one of said skin members and having a crown portion spaced from said skin member, said side portion of each of said rib members being relatively deflectable and said crown portion of each of said rib members being relatively stiff, and each of said stiffeners being made of a nonmetallic material. ### Claim 2 (depends on 1) A vehicle body as set forth in claim 1 wherein said nonmetallic material is a thermoplastic material. ### Claim 3 (depends on 1) A vehicle body as set forth in claim 1 wherein each of said rib members defines an extended pocket, and wherein each of said plurality of stiffeners includes a reinforcing member, said reinforcing member of each of said stiffeners being insertable into said pocket of said rib member thereof. ### Claim 4 (depends on 1) A vehicle body as set forth in claim 1 wherein each of said rib members includes opposite inner and outer surfaces, each of said rib members being made of a nonmetallic material, and wherein each stiffener includes a reinforcing member supported on said inner surface of said rib member of each of said stiffeners, said reinforcing members being made of a nonmetallic material that is different from said nonmetallic material of which said rib members are made. ### Claim 5 (depends on 1) A vehicle body as set forth in claim 1 wherein each of said skin members overlaps another of said skin members to form a lap joint, and wherein one of said stiffeners is positioned in straddling relation over said lap joint. ### Claim 6 (depends on 1) A vehicle body as set forth in claim 1 wherein each of said stiffeners includes an inner surface, and an outer surface having an arcuate outer surface portion. ### Claim 7 (depends on 1) A vehicle body as set forth in claim 1 wherein each of said stiffeners includes means for reinforcing said crown portion of each of said rib members. ### Claim 8 (depends on 7) A vehicle body as set forth in claim 7 wherein said means for reinforcing said crown portion of each of said rib members includes a reinforcing member made of a nonmetallic material. ### Claim 9 A vehicle body comprising top, bottom, and opposite side walls interconnected to form a box-like structure, said side walls including a plurality of skin members, each of said plurality of skin members having edges, said skin members being arranged in edge to edge relation and being respectively adhesively bonded to one another to form a sheet-like side wall panel; and a plurality of stiffeners for reinforcing said sheet-like side wall panel, said stiffeners being adhesively bonded to said skin members, and each of said stiffeners being made of a nonmetallic material, wherein each of said stiffeners has a parabolically shaped outer surface. ### Claim 10 A vehicle body comprising top, bottom, and opposite side walls interconnected to form a box-like structure, said side walls including a plurality of skin members, each of said plurality of skin members having edges, said skin members being arranged in edge to edge relation and being respectively adhesively bonded to one another to form a sheet-like side wall panel; and a plurality of stiffeners for reinforcing said sheet-like side wall panel, said stiffeners being adhesively bonded to said skin members, and each of said stiffeners being made of a nonmetallic material wherein each of said stiffeners includes a flattened outer surface portion and arcuate surface portions, each of said arcuate surface portions of each of said stiffeners extending from said flattened surface portion thereof toward one of said side walls of said box-like structure, and said arcuate surface portions and said flattened outer surface portion of each of said stiffeners combining to provide each of said stiffeners with a parabolic outer surface. ### Claim 11 An intermodal container comprising a top wall including a plurality of lock-receiving connectors, a bottom wall including a plurality of lock-receiving connectors, and a side wall extending vertically between said top and bottom walls, said side wall including a side panel having an interior surface and an exterior surface, said side panel being made of a nonmetallic material, and said side wall including a plurality of stiffeners, each of said stiffeners being adhesively bonded to said exterior surface of said side panel, wherein each of said stiffeners includes a vertically extending rib member having an outer surface which is parabolically shaped when viewed in cross section taken along a horizontal plane. ### Claim 12 An intermodal container comprising a top wall including a plurality of lock-receiving connectors, a bottom wall including a plurality of lock-receiving connectors, and a side wall extending vertically between said top and bottom walls, said side wall including a side panel having an interior surface and an exterior surface, said side panel being made of a nonmetallic material, and said side wall including a plurality of stiffeners, each of said stiffeners being adhesively bonded to said exterior surface of said side panel, wherein each of said stiffeners includes a vertically extending rib member having an inner surface and a pair of opposed projections extending from said inner surface, said projections defining therebetween a vertically extending interior pocket, and wherein each of said stiffeners includes a reinforcing member which is supported on said inner surface of said rib member and which is insertable into said interior pocket. ### Claim 13 A vehicle body comprising a top wall, a bottom wall, and a side wall interconnecting said top and bottom walls, said side wall including an upper rail made of a nonmetallic material, a lower rail made of a nonmetallic material, a plurality of sheet-like members being made of a nonmetallic material and being adhesively bonded together to form a side panel, said side panel being adhesively bonded to said upper rail and being adhesively bonded to said lower rail, and a plurality of stiffeners adhesively bonded to said sheet-like members to reinforce said side panel, each of said stiffeners being made of a nonmetallic material and each of said stiffeners including a side portion extending from one of said sheet-like members and including a crown portion spaced from said one of said sheet-like members, said side portion of said stiffeners being deflectable relative to said sheet-like members and to said crown portions. ### Claim 14 (depends on 13) A vehicle body as set forth in claim 13 wherein each of said sheet-like members overlaps another of said sheet-like members to form a lap joint therebetween, and wherein one of said stiffeners is positioned in straddling relation over each of said lap joint. ### Claim 15 (depends on 13) A vehicle body as set forth in claim 13 wherein said upper rail of said side wall includes an inwardly extending flange, and wherein said top wall includes a roof bow made of nonmetallic material, said roof bow being supported by said inwardly directed flange of said upper rail, and a roof panel. ### Claim 16 (depends on 13) A vehicle body as set forth in claim 13 wherein said lower rail of said side wall is Z-shaped, includes an inwardly extending upper flange, and includes an outwardly extending lower flange which extends outwardly beyond said stiffeners. ### Claim 17 (depends on 16) A vehicle body as set forth in claim 16 wherein said bottom wall includes a crossmember supported by said lower rail of said side wall, and a floor section supported on said crossmember, said floor section overlapping said upper flange of said lower rail.
