Suspended Concrete Floor Slab Section Detail

Assemble and erect formwork for slab2.

Suspended concrete floor slab section detail. 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. The suspended reinforced concrete slab is tied into the external capping beam at floor level. They are normally pre fabricated offsite and transported by truck. The slab is constructed on well compacted granular fill crushed stone or marl.

Added rooms can use slab on ground or suspended slabs. 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.

The design of suspended floors should conform to requirements of aci 318 and aci 421 1r. In such application the suspended slab can be concrete slab on metal deck formed concrete slab or precast concrete deck. Prepare and place reinforcement for slab3.

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. Construction details excavation construction started with the removal of topsoil and excavation for footings. To form this type of slab requires temporary beams columns and plywood as floor supports for the concrete. The mesh reinforcement in the slab is placed in the top with 1 covers.
