| The supporting structure for the glass stairs and the elevator in the UP position. Note the elevator's supporting hydraulic piston. On the right side, you can see the lower edge of the stairway's glass sidewall. The stairs are supported by connections to the elevator glass wall (on the inside of the spiral), and the glass sidewall (on the outside). In turn, the sidewall is supported by arched-shaped glass pieces attached to the elevator wall, the floor, and the ground-floor platform. |
