Definitions

  • the invention relates generally to vehicle bodies such as trailer or truck bodies, intermodal shipping containers, and the like, and more particularly to floor constructions used with those vehicle bodies.
  • a known floor construction for a vehicle body such as a trailer body or intermodal shipping container, includes hardwood floor boards supported on metallic crossmembers that extend laterally between lower metal side rails and that are secured to the side rails with fasteners. The floor boards are screwed in place on the crossmembers .
  • An example of the foregoing floor construction is provided in U.S. Patent No. 4,703,948 issued November 3, 1987 to Ehrlich. Wooden floor boards are becoming increasingly expensive and are harder to obtain due to the shrinking availability of suitable hardwoods worldwide. Floors made of wood are also susceptible to leakage due to expansion/contraction of the floor boards. Additionally, the considerable amount of metal used in conventional floor constructions adds significantly to the overall weight of the vehicle body and presents maintenance problems due to corrosion.
  • Insulated or refrigerated floor constructions also include floor boards or sections ultimately supported on steel crossmembers secured to the metal side rails with fasteners.
  • the hardwood flooring is often replaced with "T" duct metal floor sections that provide for air circulation beneath the cargo.
  • U.S. Patent No. 5,054,843 issued October 8, 1991 to Gray illustrates a sandwich floor structure supported on lateral I-beam crossmembers.
  • the sandwich floor structure includes metal stringers and insulating foam sandwiched between an underpan and a "T" duct floor section.
  • U.S. Patent No. 3,453,839 issued July 8, 1969 to Sabin illustrates an intermodal container intended to provide improved air circulation around cargo.
  • the floor construction of that container includes longitudinally extending I-beams that support a sandwich floor structure including wooden stringers and insulating material sandwiched between a subpan and an inverted "T" duct floor section.
  • the floor constructions illustrated in the Gray and Sabin patents are, like the aforementioned floor construction using wooden floor boards, somewhat heavy.
  • the floor constructions of Gray and Sabin are also susceptible to a degree of corrosion due to their use of metal components and present potential leak sites associated with fasteners and seams.
  • That container includes a floor constructed of laterally extending panels or sheets supported by lateral ribs. The sheets and the ribs are pultruded of fiber- reinforced plastic composite material and are adhesively bonded to the side walls.
  • That floor construction provides weight savings since metal crossmembers and fasteners are avoided. That construction also avoids leaks associated with fasteners since fasteners are replaced in large measure with adhesive material to provide sealed joints.
  • the invention provides a vehicle body including an improved lightweight floor assembly that is sealed against leaks and that is structurally capable of withstanding the loads encountered during a life of rigorous service.
  • the floor assembly is made substantially entirely of lightweight non-metallic material, and the components of the floor assembly are interconnected with adhesive bonds that seal the floor assembly against leaks. Any potential use of fasteners to replace or supplement sealed adhesive bonds in certain locations occurs in areas that are outside the vehicle body envelope so as not to risk compromising the integrity of the sealed interior of the vehicle body.
  • the vehicle body is also designed to provide sealed joints at the interfaces of the floor and the side, front and rear walls of the vehicle body.
  • the floor assembly includes a floor section having a substantially continuous, sheet-like panel supported by longitudinally extending beams or reinforcing members which are preferably formed integrally with sections of the sheet-like panel.
  • the sheet-like panel interfaces with the longitudinal lower rails at double lap adhesive joints that provide double bonds and seals between the floor section and side walls to insure a structurally sound and sealed floor assembly.
  • the floor section includes floor panel members that each include a sheet-like panel section and reinforcing members extending downwardly from the panel section.
  • the floor panel members are adhesively bonded together and are made of fiber- reinforced plastic composite material and formed via an automated manufacturing process such as pultrusion.
  • the reinforcing members preferably have an enlarged lower cross-section to resist bending moments resulting from downwardly directed loads on the floor and to provide a larger bonding surface.
  • the reinforcing members each have an inverted "T" shape.
  • the floor assembly also includes lateral crossmembers that extend between the lower rails of the vehicle body and that are adhesively bonded thereto with the aid of shear clips and/or that are attached thereto via fasteners.
  • the crossmembers are also preferably formed of fiber-reinforced plastic composite material via pultrusion and have an enlarged upper surface for bonding to the enlarged lower portion of the longitudinally extending reinforcing members in the floor section.
  • the invention provides a lightweight vehicle body, such as an intermodal shipping container, including a sealed, weathertight bottom wall or floor assembly that extends between the opposite side walls of the vehicle body.
  • the floor assembly includes a floor section constructed of longitudinally extending pultruded floor panel members made of fiber-reinforced plastic composite material.
  • the floor panel members each include a sheet-like panel section and integral longitudinal reinforcing members that extend downwardly from the panel section and that each have an inverted "T" shape.
  • the panel sections of the floor panels overlap and are adhesively bonded to one another to form a sheet-like panel that has sealed, fastenerless longitudinal joints and that provides a planar cargo supporting surface.
  • the sheet-like panel overlaps and is adhesively bonded to the lower rails of the vehicle body (which are preferably also pultruded of fiber-reinforced plastic composite material) to provide sealed, fastenerless interfaces between the floor assembly and the side walls.
  • the floor assembly also includes lateral crossmembers extending between the lower rails for supporting the floor section.
  • the crossmembers are also preferably formed of fiber- reinforced plastic composite material via pultrusion and are adhesively bonded to the lower rails with the aid of shear clips (or fasteners in some embodiments).
