FLAT CEILING SLABS
The Bass Beams type 1045 and 1055 are prestressed beams with a flat ceiling composite concrete slab. The soffit can either be painted or skimmed to provide a smooth flat ceiling. The Beams are economically and efficiently crane erected on either brickwork or steel and are used as a permanent shutter requiring only to be propped once at the mid span.
The amount of in-situ concrete and additional reinforcing is dependent on the load requirements, but will be less than that of a conventional slab, due to the inherent strengths of the prestressed Bass Beams.
A minimum of 0.15% of the final cross section must however always be provided to comply with the minimum requirements of the design codes.
An engineering design of the composite slab is very versatile and additional reinforcing can be placed on the erected beams to cater for specific loads and the depth of the insitu concrete can be varied to meet different loading or span requirements.
The increasing demand for housing and insufficient land to accommodate the demand required, determine the need for a suspended slab system. With the Flat Slab by Bass Beams one meets the various requirements, for example: Flat Soffit, accommodation in the minimum space, fast and efficient erecting; therefore time saving as well.
The demand for housing ensures that concrete slabs will continue to be in demand for years to come, particularly in the growth of township / suburban areas and the trend towards duplexes and tenement housing.
Erection of Flat Slab
- Minimum bearing - 100m unless otherwise specified by engineer.
- Minimum screed 70mm 30MPa unless otherwise specified by engineer.
- Reinforcing BRC mesh.
- Propped once at the mid span.
- Electrical conducting can be laid on top of Flat Slab and covered with the required screeding.
- Prop removed once topping reached MPa requirement.
