Plastic Formwork System for Waffle Slab Ceilings "Skydome"
SKYDOME
"Sky Dome" is a formwork system for creating waffle-shaped ceilings, which helps reduce slab weight and prevents structural failure during earthquakes due to its T-shaped rib cross-section.
The "Sky Dome" is a modular formwork system designed to create a dome-shaped concrete ceiling with a waffle pattern. This shape allows for a reduction in slab weight and improves seismic resistance through robust T-shaped rib cross-sections, enabling the construction of large-span structural frameworks with minimal columns and beams. Additionally, the waffle-shaped dome structure reduces and attenuates reverberation within the dome, providing excellent acoustic performance. * Unique visual effects created by the ceiling shape * Five types of formwork heights (dome depths): 200, 250, 300, 350, and 400 mm * Material: ABS resin * A ceiling formwork system that can be reused over 100 times * No tools required, making the work easy, quick, and cost-effective due to reduced use of concrete and steel * Easy demolding without the need for release agents * Simple cleaning with high-pressure water washing

Applications/Examples of results
This is a plastic formwork system for dome-shaped ceiling slabs in buildings. The formwork is supported from below by poles to create a vaulted ceiling space. The Sky Dome was adopted for the construction of the 4,500 square meter bidirectional lightweight slab of the multipurpose building "Le Nuage," designed by Philippe Starck in Montpellier, France.
