ABSTRACT:
A towable unified floor frame assembly derives lengthwise strength from two elongate I-beams disposed symmetrically about a longitudinal axis. The I-beams are separated by a plurality of angle-sectioned metal cross members welded therebetween. A plurality of trusses, corresponding in number and location to the metal cross members, is disposed to support an outer perimeter and a floor thereabove. Each truss incorporates upwardly inclined bracing elements located outwardly of the I-beams connected to flat metal connecting elements individually unified to the I-beams, preferably by welding. A waterproof and dirt-excluding cover entirely covers the underneath of the floor frame assembly. Heating and ventilating ducts, power and telephone wires, water and waste pipes, thermal insulation and the like, are installed within the floor frame assembly. The entire floor frame assembly, and any superstructure built thereon, may be readily towed to a selected location on a plurality of wheels detachably mounted to brackets provided underneath the I-beams, a towing force being applied by a forwardly disposed detachable towing hitch. The floor frame assembly and its superstructure to rest on the wheels and a jack supporting the towing hitch or, optionally, may be supported underneath the I-beams by externally provided support elements.
