Ultra-lite modular composite building system

A lightweight, wall panel component for a modular building, said wall panel component comprising:

• an elongated membrane configured, in cross-section, as a series of flat sections and alternate hollow tubular sections interconnected in series and extending continuously from one end to the other end of said wall panel component;
• and
• a structural foam bonded to, encapsulating and laterally bracing said elongated membrane, said elongated membrane, laterally braced by said structural foam forming a primary support structure operable for carrying a vertical load of a building, wherein said hollow tubular sections of the elongated membrane enhance the membrane's resistance to buckling under vertical load and the extremities of said elongated membrane of said wall panel component top and bottom edges expose said structural foam and said elongated membrane ends including the hollow tubular sections which are operable to receive a connected series of hollow dowels to facilitate an interconnection of both vertically and horizontally aligned building components as well as pass-through of utilities after erection of panel components to form a building frame.

A lightweight, wall panel component for a modular building, said wall panel component having a first end and a second end, a first edge and a second edge and opposing generally flat wall surfaces, said wall panel component comprising:

• an elongated membrane extending straight, and without longitudinal bending, between said first end of said wall panel component and said second end of said wall panel component and being configured, in cross-section, having at least one flat section and at least one hollow, tubular, column section, said flat section being interconnected with said hollow, tubular, column section;
• and
• a structural foam forming said opposing generally flat wall surfaces and being bonded to, encapsulating and laterally bracing said elongated membrane, said elongated membrane being laterally braced, by said structural foam and said elongated membrane forming a primary support structure operable for carrying a vertical load of a building, wherein said at least one hollow tubular section of the elongated membrane enhances the membrane's resistance to buckling under vertical load.

A floor system as defined in claim wherein:

• the floor beam is comprised of a rigid hollow tube with continuous rigid vertically aligned plates two of which are located at opposite side external tangent points of said tube and a central one of which bisects the tube and projects above and below its perimeter, the entirety of rigid vertically aligned plates and the rigid hollow tube is encapsulated by, bonded to and laterally braced by the expanded polymeric foam with bisected hollow tubular openings exposed at opposite ends of the hollow tube and foam matrix composite to facilitate both structural connection purposes and pass-through of utilities.
