Concrete Ground Floor Slab Detail

There are three general types of ground floor construction.

Concrete ground floor slab detail.

Aci 302 1r provides guidelines and recommendations on. The ground floor is made up of suspended concrete slab or beam and block floor supported by the external and internal load bearing walls which transfer the loads to the foundations below. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Wearing concrete slab the floor slab that contains either a square fabric mesh or fibres.

Concrete slab ground floors in a solid or ground bearing because it is continuously supported by the ground across its whole area concrete floor the choice of insulation position relative to the concrete slab is commonly linked to the building s heating system. Conventional concrete has high embodied energy. Both pre cast concrete planks or slabs can be used as well as cast in situ reinforced slabs along with beam and block systems. Concrete slab floors come in many forms and can be used to provide great thermal comfort and lifestyle advantages.

Steel reinforced slabs typically between 100 and 500 mm thick are most often used to construct floors and ceilings while thinner mud slabs may be used for exterior paving see below in many domestic and industrial buildings a thick concrete slab supported on. A typical way of constructing a solid floor would be to provide a base of hardcore with sand blinding with a layer of concrete over that. Joints in ground bearing slabs tend to be present for two reasons. In 1978 nzs 3604 became the standard for slab on ground floors.

Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate. We would like to show you a description here but the site won t allow us. They can be insulated both underneath and on the edges. Ground bearing floors shall be of adequate strength and durability and use concrete mixed and reinforced as necessary to support floor loads safely and resist chemical and frost action.

Integral or separate slab construction was typically. In terms of the buildability most floor slabs have joints within them due to the limits of how much concrete can be poured in a day. For design of slabs on ground with the exception of highway and airport pavements parking lots and mat foundations. 1 2 2 aci committee 302develops recommendations for construction of slab on ground and suspended slab floors for industrial commercial and institutional buildings.
