Suspended Concrete Floor Slab Section Detail

To form this type of slab requires temporary beams columns and plywood as floor supports for the concrete.

Suspended concrete floor slab section detail. Suspended slabs are made of concrete and steel mesh the same as a ground slab. They are normally pre fabricated offsite and transported by truck. See section 1 2 for relevant work by these and other committees. The suspended reinforced concrete slab is tied into the external capping beam at floor level.

Added rooms can use slab on ground or suspended slabs. 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. Pour compact and finishing concrete floor slab4. Concrete floor slab construction process includes erection of formwork placement of reinforcement pouring compacting and finishing concrete and lastly removal of formwork and curing of concrete slab.

Suspended floors are also used when the water table is high or when aggressive chemicals are present in the soil that may attack the concrete slab. The design of slabs on ground should conform to the recommendations of aci 360r. The slab is constructed on well compacted granular fill crushed stone or marl. Refer to aci 223 for procedures for the design and construction of shrinkage compensating concrete slabs on ground.

Back to garage foundation. Construction details excavation construction started with the removal of topsoil and excavation for footings. Detail 5 is an option where the garage floor is built as suspended concrete slab for parking while below is a living space or storage. The design of suspended floors should conform to requirements of aci 318 and aci 421 1r.

Some slabs have hollow channels running through them these hollow core slabs are used to help reduce weight and also to allow cabling and piping to be run through the slab. Contents concrete floor slab construction process1. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Concrete slab floor construction was often used for internal garages or lower levels of split level houses with suspended floors used for other parts of the house.

This slab design can only work for a slab clear span of 14 feet which is only good for one car garage 2 cars if parked behind the other not side by side. 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. In such application the suspended slab can be concrete slab on metal deck formed concrete slab or precast concrete deck. Renovations can often incorporate concrete slabs even when the original building does not.

Assemble and erect formwork for slab2. Prepare and place reinforcement for slab3. The top steel reinforcement is important. The mesh reinforcement in the slab is placed in the top with 1 covers.
