What is concrete ground floor?
A solid ground floor consists of a layer of concrete, which in the case of a domestic building will be the surface layer brought up to ground floor level with hardcore filling under it. The advantage of a solid ground floor is the elimination of dry rot and other problems normally associated with hollow joisted floors.
How are concrete floors supported?
Supports for floors are typically beams, columns or walls. In situ concrete reinforced suspended floors can be designed to span one-way or two-ways between supports. Such floors can be designed and constructed to have a continuously flat soffit.
What is the minimum concrete floor slab thickness when supported on the ground?
1.3 Minimum thickness of Slab on the ground UBC recommends minimum thickness of Concrete floor slabs supported directly on the ground to be 89mm, whereas BCGBC4010A – Apply structural principles to residential low-rise constructions determined minimum thickness to be 100mm.
What is a supported floor?
Ground-supported concrete floors are used in many types of building, ranging from simple houses through to schools, factories, and very large warehouses. As the floor type name implies, any loads imposed on the concrete floor are carried directly and fairly uniformly by the ground under the floor.
What is the purpose of a concrete floor slab?
Simply, a floor slab functions to distribute without deformation or cracking, the loads applied to it to the weaker sub-grade below, in the case of a ground bearing slab, or to the piles supporting it if designed as a suspended ground slab, and to provide a suitable wearing surface upon which the operations in the …
Do I need DPM on concrete floor?
Do I need a DPM under laminate flooring? Simply put yes. In order to prevent damp rising through the concrete floor and causing issues, a DPM should be used under all final floor types including wood flooring, laminate, vinyl and floor tiles.
Do I need steel in my concrete floor?
Concrete that carries heavy loads (such as footings, foundation walls and columns) almost always requires reinforcing steel. Not all concrete work requires reinforcing though. Concrete projects such as pathways, some driveways and small shed or playhouse floors, generally do not require any steel reinforcing at all.
What is the difference between ground floor and suspended floor?
A suspended floor is a ground floor with a void underneath the structure. Unlike standard ground floor construction, suspended floors are not sitting directly on the ground. This allows air flow and ventilation to prevent the mould and dry rot that would otherwise occur over damp ground.
What do floor joists sit on?
At the foundation level, floor joists rest directly on a sill that is treated with preservative so that contact with the foundation will not promote termites or rot. Their exact construction and connection with the wall studs depend on the method of framing that is utilized.
When to use a ground supported concrete floor?
Ground-supported concrete floors are used in many types of building, ranging from simple houses through to schools, factories, and very large warehouses. As the floor type name implies, any loads imposed on the concrete floor are carried directly and fairly uniformly by the ground under the floor.
What are the different types of concrete floors?
Concrete floors can either be: Basement or ground floors – the concrete slab is directly supported onto a construction which may involve hardcore, blinding and other materials . Suspended ground floors – where the slab is supported on beams and/or loadbearing sleeper walls and is not in direct contact with the ground .
What can concrete floor slabs be used for?
A solid concrete floor slab can be used to act as a ‘ membrane ‘ supported on columns without beams. This can prove more economic than hollow block construction in low-rise buildings up to four storeys -high. As span and load increase so does the slab thickness. Two-way spanning slabs may be used for higher loads and longer spans.
What is the construction process for a concrete floor?
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. 1. Assemble and Erect Formwork for Slab 2. Prepare and Place Reinforcement for Slab 3. Pour, Compact and Finishing Concrete Floor Slab
