Installation & construction Notes
1. Longspan Lintels supply Kwiklin beams in matched pairs in standard lengths of 5,4m, 6,45m, 7,5m or 8,55m cut into lengths as required.
2. The supporting columns must be constructed (Use min quality 7 MPa bricks and blocks) as directed by engineer. Structure must be well cured, sound and level before placing beams. (Non shrink grout can be used to level up and bond top brickwork if necessary).
3. Set up secure scaffold and heavy duty boards to accommodate required lifting crew for placing manually. Longer beams may require a crane or lifting tackle which can be provided.
4. Beams must be lifted with two slings on a spreader bar when using a crane or tackle.
5. Set up and line up the two Kwiklin beams
Tap the required number of laminating galvanised steel bushes.
Using locating saddles clipped onto the bushes, set reinforcing in place as required by engineer.
Caulk the gap between the beams or tie up a shutter board when creating a wider beam (260/280mm wall applications)
Set-up single prop in centre of beam assembly.
Cast 40 MPa concrete into beam (16 litres required per running meter)
6. Steel imbedded in supporting column brickwork should be secured through the joint in the Kwiklins and tied in by the concrete infill in the bearer beam to create a connected structure.
7. Where practical, it is advisable to place the first course of brickwork immediately above the Kwiklin assembly as a header course.
8. Subsequent course to be laid with galvanised brickforce in the mortar joints.
9. Alternatively, the strength of the beam can be further increased by integrating reinforcing up through the upper brickwork constructed as a cavity wall so as to admit further reinforced concrete infill between the leaves.
10. Hoop iron can also be wrapped around reinforcing bar and passed up through the brickwork to secure the roof rafters, before casting concrete beam infill.

Notes
1. The tables satisfy SABS 0100 - Latest revision
2. Calculations for table prepared by MR. Colin Dunn - Endecon PE Trust (Eng. Reg.)
3. Kwiklins can be further reinforced by intergrating reinforcing to the upper brickwork constructed so as to admit concrete infill between leaves.
4. Kwiklins spanning 6m clear with concrete infill and steel reinforcing, will carry 10 courses of brickwork without sagging. It is advisable to fit a temporary prop under the centre of the Kwiklin assemble during construction when time does not permit for infill concrete or brickwork to set.
5. Kwiklins must be applied under supervision and specifications of a professional engineer.
6. Kwiklins sets are produced in standard lengths of 5.4m, 6.45m, 7.5m and 8.55m and can be cut to special order lengths.
7. Mass 51kg per meter per single beam.
