29 – Skeleton

The staircase is possible to be the playground for children, so a slide is combined into the staircase. Morphologically, inspired by the whale skeleton, the staircase is not only the mimicry of organic form but shows the order and firmness of the skeleton. Structurally, two concrete ring beams running through the staircase support the cantilevered steps and the slide. Seventeen identical precast units are adopted that reduce the complexity of the production, minimize the cost and increase the feasibility. The components are locked together by the convex and concave joint and connected by two concrete beams. Materially, Ultra-High-Performance Concrete is chosen as the main material.
