Precast Concrete Lintels
 

COMPOSITE LINTELS
These lintels utilise the composite action of the concrete and brick/blockwork together to provide their load-bearing capacities as shown in the table overleaf.

Three courses of brickwork are equivalent to two courses of blockwork. As the brickwork mortar matures, lintels of over 1200mm spans should be propped at 1200mm centres. bearings at each end must be at least 150mm. A damp-proof course, when used, must be strong and plastic enough to avoid cracking and be placed so as not to break the lintel/blockwork bond. ideally the d.p.c. should not be included in the composite wall joist at all, but if essential then it should be only tucked in 30mm.

NON-COMPOSITE LINTELS
Where a higher load-bearing capacity is required, or there is insufficient brickwork above to allow adequate composite action, non-composite lintels are the solution.

No propping is necessary during construction and also wall plates, trusses and floor joists can be accommodated as directly imposed load in accordance with the table overleaf. bearings at each end must be at least 150mm and for lintels of over 3 metres, 200mm long bearings are recommended.

Non-composite 215mm x 100mm lintels must be installed with the triangle of reinforcement in the bottom the lintel.

The table above is for safe working, uniformly distributed loads applied to the composite construction in kN/m exclusive of self weight of brickwork within the construction and the weight of the lintel. The design is based on the brickwork having a limiting crushing strength
of 10.4 N/mm2.
