Abstract: An orthogonal framework for the fabrication of modular buildings includes a plurality of hub members formed to fit in the ends of vertical hollow post members including base hubs for securing the lower end of a hollow post to a foundation and/or base beams or shear panels, terminal hubs for securing the top ends of a post upper beam members and/or the upper ends of shear panels, and intermediate tubes for securing the ends of two vertically aligned posts together and/or to support beams for the building. The hubs are hollow and have press nuts mounted on their inner surfaces to allow the terminals to be bolted to the posts, beams and shear panels in a large variety of beam and post combinations to form modular buildings in various configurations.

Abstract: An orthogonal framework including L shaped brackets connected to a hollow support tube by bolts and press nuts with the short leg of the brackets against the tube and the long legs extending therefrom and a pair of beams bolted to the long legs of the brackets provides an exceptionally strong framework made of exceptionally light structural elements which can be readily mass produced and assembled.
