Graphical Construction Glossary >> Concrete and Concreting. >> >> Concrete Suspended Slab
Suspended concrete slabs are the basis of multi storey building construction apart from small structures of two or three floors that may used timber and some pre-cast concrete materials.
The photo above shows a small residential slab that uses a cheap and efficient method of forming the slab using a propriety system (Bondek)of galvanised roll formed sheets that are left in place after the concrete is poured. The Bondek sheets not only make the formwork simple but they also provide strength to the slab so reducing the need for reinforcing steel. Quite possibly the slab above uses only one layer of weld-mesh to reinforced the slab.
The main method of constructing a suspended slab is to use ply sheets on timber with plenty of supports. Here is a page with some details of suspended slab formwork.
