How to Choose a Floor Structure | Homebuilding & Renovating27 Jun 2016 ... suspended concrete flooring systems were originally developed as a means of overcoming ground problems such as unstable sloping sites, where it made sense to bridge deep gaps rather than fill them. Today ... The pre-cast reinforced concrete beams are laid in rows in a similar fashion to traditional timber joists, with their ends resting on the inner leaf of the main walls over the damp-proof course (DPC). ... hollow Core Ground floors An Even Quicker Solution.

Precast Concrete Composite Flooring, Suspended Concrete FloorThe dense nature of the product eliminates possible fire spread through hollow cores. Precast concrete floor units have a special shear key detail on the long edge. This joint is designed to receive the insitu screed without additional shuttering to the soffit. suspended concrete floors constructed with ACP's composite flooring can be designed to eliminate additional ceiling finishes in many cases. A smooth soffit finish to the precast floor is a benefit of the wet cast system and is suitable to ...

Concrete slab - WikipediaThe first is the question of insulating a floor slab. In older buildings, concrete slabs cast directly on the ground can drain heat from a room. In modern construction, concrete slabs are usually cast above a layer of insulation such as expanded polystyrene, and the slab may contain underfloor heating pipes. However, there are still uses for a slab that is not insulated , typically in outbuildings which are not heated or cooled to room temperature. In those cases, casting the slab directly onto a ...
