Tower Hollow Construction Cutaways.
Mouseover alternates views.
We have explored a hollow construction for the stone covered portion of the pylons; as opposed to the concrete core, while the glass portion and light placements are constructed in the same manner as Design One.
Four angle cross-section spars form the frame; with thin polished flat bars welded to their upper extremities and extending above the steel/glass interface into the glass portion for stability.
A steel interface shelf forms the upper surface of the frame and supports the glass.
A silicone pad upon the interface shelf cushions the glass structure and allows for different coefficients of expansion.
The frame is sheathed in perforated steel; allowing a secure, flat surface upon which to afix the stone veneer.
