Abstract
The invention comprises a two-part support member for curtain walls capable of withstanding the extreme loads required for extra-large walls with minimal deformation comprising two independently extrudable components, each of which may be produced on standard extruders and attachment means that holds the extrudable components together. The sections fit together in such a way that inevitable deformations that occur during production are taken into account and corrected for. Due to the hitherto unattainable stiffness values that this combination of components may reach, extra-large curtain walls mounting and supporting is achieved that was otherwise unattainable. The cross sectional area of the sections is relatively small allowing for lightweight members to be extruded that use a minimum of material.
Claims9
A support member for curtain walls comprising a front holding cap and a back support section, wherein said back support section is comprised of:
- (a) a first support member component and a second support member component forming a multi-component support section, wherein, said first and said second support member components fit one another and are locked together, wherein said first support member component has a first flange and a second flange, and wherein said second support member component has a third flange and a fourth flange, wherein when said first and said second support member components are locked together, said first flange and said third flange interlock and said second flange and said fourth flange interlock;
- (b) an attachment means that holds said first and second support member components in compression, said attachment means is a threaded fastener inserted through a support member component in a parallel manner to the support member length, and screwed in compression into a threaded section in the other support member component;
- (c) wherein said support member allows for increased values of moment of inertia and stiffness to be reached, enabling the support of extra-large curtain walls with a minimum of deformation.
