Structural section

Abstract

This specification discloses an improved structural section for use as a beam or rafter and comprising two similarly profiled metal sections joined together so that their profiles define a central box-section and a plurality of spaced stiffener members located within the box-section to render the box-section substantially rigid. The box-section may be of any preferred shape. For example, two metal sections with V-shaped profiles may define a central square box-section or two metal sections with trapezoidal shaped profiles may define a generally hexagonal box-section. The specification also discloses the use of a connector plate for transferring horizontal loads applied to the section to the box-section and comprising a cut-out on one side of the plate having a shape corresponding to the profile in one of the metal sections. The plate is shaped to engage the top of the section to positively locate the plate in position. The section is adapted for use with a column having a spigot shaped correspondingly to the box-section for insertion therein.
