Modular integral floor construction for vehicle body

A vehicle body comprising

• a top wall,
• a pair of opposite side walls extending downwardly from said top wall, and
• a bottom wall extending between said opposite side walls, said bottom wall including an upper surface, and a plurality of laterally extending modular floor panels adhesively bonded to one another in adjoining series relation to form joints between adjoining ones of said floor panels, each of said floor panels including a panel pultrusion, said panel pultrusion being formed as an integrally molded one-piece hollow member, said panel pultrusion being made of a composite material, said composite material including a filamentary material, and a resin binder material, and said panel pultrusion including a floor section, said floor section including vertically spaced apart upper and lower sheet members, said upper sheet member including an upwardly facing surface forming a portion of said upper surface, a plurality of vertically extending webs interconnecting said upper and lower sheet members, said webs separating said panel pultrusion into separate interior compartments, and said webs including a pair of opposite end webs, and a central web intermediate said opposite end webs, said central web having a thicker cross-section than the remaining ones of said webs, and each of said webs including a portion of said filamentary material, said portion of said filamentary material in said webs being predominantly oriented in a horizontal direction, means for interfitting said floor section with the floor section of an adjoining one of said floor panels to form one of said joints, and means for reinforcing said floor section against bending moments applied to said panel pultrusion as a result of downwardly directed forces on said upper surface, said means for reinforcing said floor section including a reinforcing section extending downwardly from said lower sheet member, said reinforcing section being horizontally offset from said central web toward one of said joints to reinforce said one joint against bending moments resulting from downwardly directed forces on said upper surface, and said reinforcing member including a pair of leg members each extending downwardly from said lower sheet member, one of said leg members forming a downward extension of said central web, and the other of said leg members forming a downward extension of one of said end webs, and a base member parallel to said sheet members and spaced below said lower sheet member, said base member interconnecting said pair of leg members, and an insulating material filling said compartments.
