Abstract
A lightweight, strong, economically-manufactured, and safely transportable modular unified floor assembly includes a lengthwise wooden girder beam formed with male and female ends to facilitate cooperative integration thereby to another similar floor assembly. In another aspect of the invention, the floor assembly is manufactured with a stairwell opening of selected size and at a selected location. The floor assembly even with a stairwell opening according to this invention is strong enough to be transported comfortably and safely from its point of manufacture to the site at which it is to be located for use.
Claims20
A modular unified floor assembly having a longitudinal axis, comprising:
- longitudinal first interior beam means, parallel to the longitudinal axis, for providing interior support;
- longitudinal second interior beam means, parallel to the longitudinal axis and located on an opposite side thereof relative to said first interior beam means, for providing interior support;
- exterior longitudinal rail means, disposed parallel to the longitudinal axis for providing longitudinal support and defining a first longitudinal perimeter portion of the floor assembly;
- a longitudinal girder beam, disposed parallel to the longitudinal axis and on an opposite side of the floor assembly relative to the rail means, for providing longitudinal support and defining a second longitudinal perimeter portion of the floor assembly, the girder beam having numerous openings formed to accommodate utility elements within the floor assembly and to reduce weight;
- and
- a plurality of transverse truss means each connected to said rail means at a first end, to said girder beam at a second end, and to said first and second interior beam means respectively intermediate said first and second ends.
