Abstract
A perimeter frame used in a construction of floors or roofs of buildings, including three superior radial sub-frames, three inferior radial sub-frames, and six non-perpendicularly interconnecting top hat sub-frames, wherein each superior radial sub-frame is located between a pair of inferior radial sub-frames such that there is a 60° angle between the first and second longitudinal axes of any two adjacent radial sub-frames, and wherein the innermost blunt end portions of the superior radial sub-frames are interconnected to define a primary hexagon structure at a centre of the perimeter frame, and the innermost blunt end portions of the inferior radial sub-frames are connected to a converging region of adjoining surfaces of each adjacent pair of superior radial sub-frames to define a secondary hexagon structure around the primary hexagon structure, and wherein the overhang end portions and the outermost blunt end portions define six corners of a hexagonal perimeter frame.
