Ultra-lite building system

Abstract

An ultra-lite building system comprising a building constructed with base plates, wall panels composed of plastic core columns and foam surrounding the core columns, a plastic header assembly, plastic and foam joists and plastic or metal studs extending between said foam wall panels.

AI Technical Summary

Benefits of technology

[0019] It is, therefore, a general object of the invention to provide an ultra-lite building system operable to utilize the foam matrix itself, in combination with an adhesion to a fully encapsulated rigid sheet or membrane, for the prime purpose of laterally bracing said membrane to support high compressive axial load with minimum material expenditure. By volume, in the present invention the system is greater than 50% air, by which is created a structural matrix that laterally braces an axial-loaded membrane to produce ultimate strength. Therein, structural performance is maximized with minimum material.

[0020] It is further object of the present invention to provide a high strength but extremely light weight axial load-bearing structural foam core panels where the strength to weight ration can exceed 1000 to 1.

Problems solved by technology

Further, U.S. Pat. No. 5,448,862 discloses a prefabricated formed plastic staircase where vertical slots are provided for the insertion of reinforcing steel rods meant for embedment in concrete beams below the surface to provide stiffening for the overall structure but no assistance to the function loading on the tread surfaces.

And while such diaphragm rigidity may have been accomplished, the end product results are limited to purposes of rigid building enclosure rather than as the main building structural supporting elements.

As more pressure is applied, the wire will strain and begin to buckle and eventually bend or break at the point of compressive tensile failure.

The tendency of the wire to buckle is, however, somewhat restrained by forces generated as the wire bows and compresses the surrounding foam in the direction of bowing, but there is no support for the wire on the side opposite the direction of bowing and the wire will eventually rupture the compressed foam and fail as described above.
