Standard floor joists are usually 2 by 10 or 2 by 12 dimensional boards installed on edge.

Floor slab thickness uk.

Kiln dried softwood joists typically span up to about 4 5m between structural walls or steel beams. Minimum thickness of concrete structural elements based on aci 318 14 irc 2009 is 456 2000 and ubc 1997 is presented. As span and load increase so does the slab thickness. The term floor slab usually refers to a floor that has been formed using concrete and generally steel reinforcement and may form part of the structure of a building.

I would also suggest wet under floor heating if your looking to heat the place. This can prove more economic than hollow block construction in low rise buildings up to four storeys high. It may form the floor of a basement at ground level or at upper levels. Hope that helps gareth.

Just remember to add some extra concrete to your total order because running short is not an option. The floor joists comprise the bulk of the floor thickness. An intermediate wall with a small foundation may be needed to reduce the span and keep the thickness of the floor joists to a minimum. Would be much cheaper than radiators and gives the added possibility of solar heating.

Minimum thickness of concrete slab beam column foundation and other structural members is selected to meet the design requirements as per standard codes. Floor structure options for first floors. A solid concrete floor slab can be used to act as a membrane supported on columns without beams. Slab thickness tolerances has long been a point of contention between contractors and specifiers.

The floors are suspended concrete and an inspection by an engineer recently when the foundations were exposed revealed that the suspended concrete floor under my flat was between 27 to 30cm and showed a surface crack and eventual chip in the surface of the slab.

Design process includes proper assumption of structural element sizes and then check. Typically a project specification will reference aci 301 specifications for structural concrete which in turn references aci 117 specifications for tolerances for concrete construction and materials. The timber floor joists should be sized correctly depending on their span length between supports and are normally laid across the shortest span from wall to wall with a gap underneath.

His inspection showed that the other flats had a concrete slab of 35 5 to 40 5cm. Can t remember the exact name of them.
