Concrete Slab Concrete Floor Construction Detail

In most cases the slab thickness is designed as an unreinforced concrete section.

Concrete slab concrete floor construction detail.

Pour compact and finishing concrete floor slab4. In this article we discuss the construction process thickness and cost of garage floor slab. Quality floor construction includes good subgrade compaction even thickness slabs low slump concrete straight bulkhead lines and control cuts spaced 24 to 30 times the slab thickness. Contents construction of garage floor slab1.

Floor slab design floors are designed as slabs on grade. 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. A concrete slab is a common structural element of modern buildings consisting of a flat horizontal surface made of cast concrete. Assemble and erect formwork for slab2.

Common mistakes in concrete floor slab construction can be avoided with proper base preparation mix design placement finishing and curing. Proper proportioning of the concrete mix joint design and performance and the slab thickness. Floor performance is influenced by. Prepare and place reinforcement for slab3.

Reinforcing is added to control shrinkage cracking and maximize the distance between designed joints. The slab thickness depends on the type of loads on the floor slab. Ground bearing concrete floor slabs should be at least 100mm thick including monolithic screed where appropriate. Contents concrete floor slab construction process1.

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. Construction details excavation construction started with the removal of topsoil and excavation for footings. 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. Footings were designed in accordance with the nzs 1900 model building.
